In some instances, grinding control logic and the like for grinding machines well known to those skilled in the art have not been described in detail in order to facilitate highlighting the subject matter of the present utility model.

The utility model is described below with reference to at least a portion of fig. 1-29.

In one possible embodiment, the present utility model provides a grinding machine production line capable of realizing single-machine automatic production of multiple grinding machines, and the grinding machine production line 100 mainly comprises a production line main body, for example, the production line main body may include (but is not limited to) a control end configured at an operation site, an acquisition end (such as a visual signal, an acoustic signal and the like) capable of acquiring grinding operations at the site, a central control end capable of analyzing and controlling the grinding operations at the site, a reminding end capable of sending signals such as voice/alarm and the like if necessary, and the like. The production line body is provided with a plurality of single machines (grinding assemblies), and on the basis of this, it is expected that the plurality of single machines simultaneously grind a silicon rod (ground square rod) group (group including a plurality of silicon rods) to be processed or select a part thereof to grind a corresponding number of silicon rod groups. Such as a plurality of stand-alone machines removably disposed on the grinding machine production line, thereby flexibly adjusting the scale of the grinding machine production line and performing operations such as replacement of the stand-alone machines or maintenance after removal. The configuration of the plurality of single units, the grinding operation mode, and the mode of arrangement thereof in the production line main body may be the same or different. Illustratively, the production line body has a plurality of grinding stations, each configured with a single machine (multiple machines may be configured where desired). The structural form, the available machining precision and the like of the single machines corresponding to different grinding stations can be the same or different, for example, one or a plurality of single machines are mainly used for machining silicon rods with more severe grinding requirements, so that the single machines corresponding to the corresponding stations are required to have higher machining precision.

In one possible embodiment, in the grinding machine production line of the present utility model, for any one grinding unit (unit capable of performing a complete grinding operation), it mainly includes a grinding assembly 1 as a single unit, a transfer mechanism 2 shared by a plurality of single units, and a loading and unloading assembly shared by a plurality of single units, wherein the transfer mechanism 2 mainly includes a gantry assembly 21 mainly including a base support portion 211, a gantry 212 provided on the base support portion, and a moving assembly 23 mainly including a lateral moving assembly 221 capable of moving the gripper assembly 23 in a longitudinal direction of the gantry, and a longitudinal moving assembly 222 capable of moving the gripper assembly 23 in a vertical direction, the gripper assembly 23 being capable of gripping and gripping the silicon rod and the gripper assembly 23 being provided to the moving assembly so as to achieve movement of the silicon rod in different dimensions by means of the moving assembly. The feeding and discharging assembly mainly comprises a feeding assembly 31 and a discharging assembly 32, a silicon rod (square rod formed after edge peeling) which is subjected to square cutting enters the production line body through the feeding assembly, and a silicon rod (usually comprising side and edge grinding) which is subjected to grinding leaves the grinding machine production line body through the discharging assembly.

As for the grinding operation for any one grinding unit, in the case of clamping the silicon rod on the clamping jaw assembly (clamping jaw assembly tightly clamping the silicon rod), the transfer of the wool rod from the feeding assembly to the grinding assembly corresponding to the grinding unit, the transfer of the finished rod from the grinding assembly to the discharging assembly and the like can be realized by means of the moving assembly.

In this example, the production line body has four grinding stations 101 (including four stations as in this example) provided along the length direction of the gantry, each of which is provided with one grinding module 1 as a single unit, and a robot (a part of the moving module other than the part of the structure of the traverse module 221) including the moving module 22, the gripper modules 23, and the like in the transfer mechanism 2 is capable of traveling along the gantry, and any one of the grinding modules and the transfer mechanism constitutes a functionally complete grinding unit. Obviously, the number of grinding stations, the relative positional relationship among the stations and the like are just one specific form of the main body of the production line, and obviously, the scale and specific construction mode of the main body of the production line can be flexibly determined according to actual requirements by a person skilled in the art. The portal frame comprises a plurality of parallel portal frames, one transfer mechanism is arranged for each portal frame, another portal frame extends along the direction perpendicular to the portal frame and can be provided with a plurality of grinding stations along the travelling direction of the other portal frame, and the like.

In one possible implementation, multiple single machines share one feeding assembly and one discharging assembly, and similar feeding and discharging control logic is adopted for the single machines. It is obvious that the structure of the feeding/discharging component can be adjusted according to actual requirements, for example, the method can include, but is not limited to, configuring a plurality of feeding components and discharging components for a plurality of single machines, such as configuring one feeding component and one discharging component for one or a plurality of single machines according to azimuth, priority, product model, attribute of silicon rods to be ground (such as specificity or importance degree of a certain batch of products, etc.), and for example, additionally configuring a single feeding component and one discharging component for a plurality of single machines along the length direction of the gantry frame, wherein a plurality of single machines share one feeding component and one discharging component, but configuring separate feeding/discharging control logic for one or a plurality of single machines (such as also according to the azimuth, priority, product model, attribute of silicon rods to be ground, etc.).

Taking a group of feeding components and a group of discharging components as an example, the transfer mechanism of the grinding machine production line is mainly used for realizing transfer between the silicon rod to be ground and the ground silicon rod among the feeding components, the grinding components and the discharging components, and performing corresponding butt joint, adjustment and other works on a feeding station corresponding to the feeding components, a discharging station corresponding to the discharging components and a grinding station corresponding to the grinding components, such as transferring the silicon rod to be ground among the feeding components and the grinding components (feeding operation), transferring the ground silicon rod among the grinding components and the discharging components (discharging operation), performing corresponding butt joint operation (such as alignment of a clamping position and the feeding/discharging components, clamping/loosening of the silicon rod in the clamping position) between the feeding/discharging components and the two, and performing joint operation such as material taking, discharging and the like on the area between the feeding/discharging components and the two.

In this example, the manipulator including clamping jaw assembly etc. in the transfer mechanism can walk on the portal frame along the direction between material loading subassembly, unloading subassembly and the different grinding stations, realizes the motion demand of manipulator walking, along the width direction of portal frame between material loading subassembly and the unloading subassembly (like in the length direction that corresponds to the grinding machine production line, can be called length direction) through the cooperation of manipulator and portal frame. And the movement of the clamping jaw assembly along the vertical direction, which is realized by the mechanical arm, can meet the movement requirement of the silicon rod approaching/separating from the grinding station along the vertical direction. In practice, the corresponding number of single grinding machines can be calculated according to the logic beats of the group control system of the grinding machine production line, so that the grinding operation and the loading and unloading operation of the silicon rod needle on the single grinding machine/the grinding machine production line can be realized through the walking of the manipulator on the portal frame and the lifting movement of the silicon rod realized by the manipulator. For example, the group control system can be combined with the number of silicon rods to be ground, the equipment state of a single grinding machine, the state of a manipulator and the like to match a proper single machine for the silicon rods or silicon rod groups to be ground currently and provide a control strategy for specific grinding operation.

The working mode of the grinding machine production line is that the manipulator starts the silicon rod to be ground from the feeding station corresponding to the feeding assembly according to the control instruction of the group control system, and the silicon rod is conveyed to a preset target position which can be connected with a single grinding machine of a target grinding station through the cooperation between the walking of the manipulator along the length direction and the width direction of the portal frame, and the target position is usually above the grinding assembly in the corresponding grinding station. In the case of delivering the silicon rod to the target position, the group control system reconfirms state information of the single grinding machine corresponding to the current delivery job, such as state information including, but not limited to, in-operation, in-debug, in-maintenance, in-fault processing, standby, and the like, based on, for example, equipment management information, and the like. After the grinding operation comprising the side surface and the edge is finished on the silicon rod by the single machine of the grinding machine, the silicon rod is firstly lifted to the upper part of the grinding component by the manipulator, and then the grinded square rod is transported to a blanking station corresponding to the blanking component through a blanking travelling path.

It can be seen that in the grinding production line of the present utility model, the functional area mainly includes a feeding station corresponding to the feeding assembly, a grinding area corresponding to a plurality of single machines (including a plurality of grinding stations), and a discharging station corresponding to the discharging assembly. Based on this, by means of the transfer mechanism, a switching of the silicon rod between different grinding stations can be achieved, an accurate butt joint between the silicon rod and any one of the grinding stations.

Based on this, the silicon rod which has been opened can be transported to the loading station of the loading assembly by means of the cantilever crane assembly 4. In the case that the feeding/discharging assembly cannot be abutted to the production line of the grinding machine, the feeding/discharging can be realized by means of a cantilever crane assembly in a manual operation mode.

The blanking component can be directly connected with the downstream process end of a grinder such as a slicing machine for slicing a silicon rod. For example, the structure of the slicing machine may be a slicing operation line including a plurality of slicing machines, and in a typical case, a degumming workshop is disposed at a downstream side of the slicing machine, and the degumming workshop mainly performs degumming treatment on silicon rods (silicon wafer groups) bonded to a wafer support and subjected to slicing operation.

Obviously, the structure is a specific structural form capable of realizing bar transmission when the sampling inspection is performed on the silicon rod, and a person skilled in the art can flexibly adjust the related driving transmission adjusting structure according to actual requirements, for example, the synchronous belt and the synchronous wheel can be matched and adjusted into a mode of matching a belt with a belt pulley, matching a guide rail with a lead screw, matching a guide rail with a gear/rack, matching a cylinder with a guide rail and the like.

When the sampling inspection assembly is connected with the blanking assembly and the preset sampling inspection condition is met, the clamping jaw assembly clamps the finished square rod which is ground to the blanking table of the blanking assembly, the finished square rod which reaches the blanking table can be transferred to the sampling inspection table by reversing the driving part of the blanking table, and sampling inspection can be performed on the current finished silicon rod based on the finished square rod. After the sampling inspection is finished, assuming that the sampling inspection of the finished square bar is qualified, the finished square bar can be transferred to a blanking table of the blanking assembly again through a sampling inspection table by enabling a sampling inspection table driving part to rotate forwards, and the finished square bar can be directly transferred to a blanking conveying line of the blanking assembly.

In one possible embodiment, the production line body is provided with a blow-drying assembly 6, such as a blow-drying assembly disposed between the blanking table assembly 321 and the blanking conveying line 322 of the blanking assembly 31. Based on this, when detecting that there is finished square rod to transfer to unloading transfer chain by the unloading platform, reduce the unloading speed of unloading transfer chain for finished silicon rod slowly passes through the subassembly that weathers, thereby weathers the residual water stain on finished square rod surface.

In one possible embodiment, the blow-drying assembly 6 mainly includes a blow-drying substrate, the blow-drying substrate includes a support frame 61, and a mounting portion 62 (such as a mounting plate) is provided on the support frame 61, and the mounting plate can be connected to the blanking assembly at a position corresponding to a position between the blanking table assembly and the blanking conveying line. Be provided with the manger plate subassembly on the support frame, the manger plate subassembly includes the relative first manger plate portion 631 (such as manger plate box etc.) and the second manger plate portion 632 that set up, and first manger plate portion and second manger plate portion form the space that allows the finished product silicon rod to pass through, are provided with manger plate brush 64 in the position that is close to the top between first manger plate portion and the second manger plate portion. The supporting frame 61 is provided with an air knife assembly 65 in the space surrounded by the first water blocking portion and the second water blocking portion, and the air knife assembly can blow air to the surface of the finished silicon rod when the finished silicon rod passes through the space formed by the first water blocking portion and the second water blocking portion.

If in order to guarantee that the surface of finished silicon rod can be dried fully, can all be provided with the air knife subassembly at bottom, lateral part and the top of support frame, for example the support frame is the structure of cuboid roughly, is close to the bottom/lateral part of support frame and corresponds, be close to or be on a parallel with the position of edge and be provided with the air knife subassembly, is close to the position of middle part (manger plate brush) at the support top to guarantee can all-round weather finished square rod.

In one possible embodiment, the blow-drying assembly 6 includes an air inlet assembly 66 and an air path assembly (not shown) from which air can pass through the air path assembly to the air knife assembly to blow-dry the surface of the finished silicon rod. In this example, the air inlet subassembly sets up in the below (bottom outside) of manger plate subassembly, and the wind knife tackle spare has all been arranged to the inside upper and lower left and right sides of weather subassembly, can guarantee to weather the finished product square bar all-round.

Obviously, the structure is only one specific structural form when the silicon rod is dried, and a person skilled in the art can flexibly adjust related structures according to actual requirements, for example, the structure can be realized by replacing the air knife assembly with other structural forms such as a nozzle, integrally forming the water retaining box, the mounting plate and the supporting frame, and the like.

In one possible embodiment, the production line body is provided with an abnormal workpiece collection assembly 7, such as an abnormal workpiece collection assembly, which is also provided in an area of the production line body that can be engaged with the blanking station. Based on this, the silicon rods that are inspected by the inspection component or that are determined directly to be unacceptable can be collected (and transported), thereby ensuring the sustainability of the grinding operation.

In one possible embodiment, the abnormal work piece collection assembly 7 basically includes an abnormal work piece collection base including a positioning assembly and a guide wheel assembly and an abnormal work piece collection trolley 71. The positioning assembly comprises a photoelectric switch 72, a limit switch 73, a rotary air cylinder 74 and the like, wherein the photoelectric switch 72 can detect whether a collection position 711 of the abnormal workpiece collection trolley is provided with a material (silicon rod), the limit switch 73 is used for detecting whether the abnormal workpiece collection trolley is pushed in place, and the rotary air cylinder 74 is used for hooking the abnormal workpiece collection trolley under the condition that the abnormal workpiece collection trolley is pushed in place so as to prevent the abnormal workpiece collection trolley from moving relative to an abnormal workpiece collection substrate after being positioned.

In one possible embodiment, the abnormal workpiece collecting matrix includes a guide wheel assembly 75, and the abnormal workpiece collecting trolley enters the abnormal workpiece collecting matrix along the guide wheel assembly and is pushed to the positioning assembly, when the front end of the abnormal workpiece collecting trolley contacts the limit switch 73, the rotary cylinder hooks the abnormal workpiece collecting trolley according to the feedback signal of the limit switch to prevent the abnormal workpiece collecting trolley from moving again, so that the positioning of the abnormal workpiece collecting trolley is completed.

It is obvious that the above abnormal workpiece collection assembly is only an exemplary description, and a person skilled in the art can adopt a suitable structure to collect abnormal silicon rods according to actual requirements, so as to ensure the sustainability of the production line of the grinding machine.

In the running process of the grinding machine production line, when abnormal silicon rods appear in any link, the abnormal silicon rods can be clamped to an empty collecting position of the abnormal workpiece collecting trolley through the transfer mechanism. If the grinding machine production line has an abnormal rod detection function, the abnormal rod can be directly clamped to the abnormal rod collection assembly through the clamping jaw assembly under the condition of detecting the abnormal rod. The abnormal workpiece collecting assembly 7 judges whether materials exist on each collecting position of the abnormal workpiece collecting trolley according to feedback signals of the photoelectric switch. When the abnormal workpiece collection trolley is full of materials (silicon rods are collected on each collection position), the abnormal workpiece collection trolley with full materials can be removed.

It can be seen that in this example, a plurality of single machines of the grinding machine production line share a group of feeding components, a group of discharging components and a group of sampling inspection components, so that the utilization rate of the feeding and discharging components is improved, the whole occupied area of the equipment of the grinding machine production line is saved, and the cost of the production line is reduced. It should be understood that the foregoing manner in which the loading and unloading assembly, the sampling inspection assembly and the abnormal workpiece collection assembly form the production line of the grinding machine is merely an exemplary description, and those skilled in the art can flexibly arrange the loading/unloading station, the sampling inspection station and the abnormal workpiece collection station corresponding to the loading and unloading assembly, the sampling inspection assembly and the abnormal workpiece collection assembly according to actual requirements. For example, the installation positions of the corresponding functional components can be flexibly adjusted according to the production requirements of different sites. The portal frame is provided with a walking path which is approximately L-shaped, and the walking path can comprise, for example and without limitation, adding an upper/lower material station, a sampling inspection station and/or an abnormal workpiece collecting station at the joint of the L-shaped structure, integrating the sampling inspection station and the abnormal workpiece collecting station to a certain extent, and the like.

[ Portal frame Assembly ]

In one possible embodiment, the gantry assembly 21 includes a base support portion 211 and a gantry 212, in which case the base support portion 211 includes a gantry frame with a gantry column disposed thereon, the gantry 212 includes a main end and a sub-end disposed thereon in parallel, and a reinforcing structure such as a connection rib 213 is further disposed between the main end and the sub-end to make the integrity of the gantry assembly better and thus make the structure more stable. The gantry assembly primarily serves as a support and provides an installation/motion environment for the moving assembly.

Lateral movement component of movement component

In one possible embodiment, the lateral movement assembly 221 includes a lateral movement drive member, a lateral movement transmission mechanism, and a lateral movement guide assembly. As in the present example, the traverse driving member is a traverse driving motor 2211, the traverse transmission mechanism is a traverse rack and pinion mechanism 2212, one of the two gantry frames (main end) is provided with a driving motor (and a traverse transmission mechanism, a traverse guide mechanism, etc.) and thus is called a main end and the other is not provided with a driving mechanism and thus is called a sub end. As in the present example, the lateral movement transmission mechanism is a rack and pinion mechanism, and it is obvious that other transmission members/transmission mechanisms such as a screw nut mechanism, a belt mechanism, a chain mechanism, etc. may be employed according to actual needs.

The lateral movement assembly 221 also serves as a support for the longitudinal movement assembly while allowing the jaw assembly 23 to traverse along the length of the gantry. Because structures such as clamping jaw assemblies, silicon rods and the like are also arranged on the transverse moving assembly, the weight born by the transverse moving assembly is large when the transverse moving assembly plays a supporting role. To ensure reliability of the supporting action, in one possible embodiment, the traverse guide assembly comprises a traverse hard rail 22131, traverse guide wheels 22132 capable of traveling on the traverse hard rail 22131, and traverse bearing wheels 22133 mainly for bearing the weight of the traverse guide assembly, and the weight is mainly borne by the bearing wheels during the process of the traverse guide assembly for bearing the weight. For example, the transverse moving hard rail can be replaced by other guide rail structures such as guide rails, optical axes and the like which can ensure transmission precision according to actual requirements.

In one possible embodiment, the moving assembly 22 includes a sliding table 223, the clamping jaw assembly 23 is disposed on the sliding table, and the lateral movement driving motor drives the sliding table to move on the lateral movement hard rail through the lateral movement rack and pinion mechanism, so that the sliding table drives the clamping jaw assembly to move along the portal frame. Therefore, the accurate movement of the sliding table and the clamping jaw assembly arranged on the sliding table along the portal frame can be realized through the servo control of the transverse movement driving motor. If can be provided with limit detection switch respectively in the slip table along its sideslip direction's both sides to guarantee that the slip table can accurately remove in its effective stroke.

In one possible embodiment, the lateral movement guide wheels 22132 of the lateral movement assembly 221 are disposed on the side (lower side) adjacent to the lateral movement hard rail 22131, and the lateral movement bearing wheels 22133 are disposed on the side (upper side) adjacent to the sliding table 223, so that the main bearing action can be shared by the bearing wheels. Such a construction enables better bearing reliability than in the case of a weight integral against a slide in a rail-slide assembly, for example.

In one possible embodiment, the sliding table 223 is provided with a lateral movement guide assembly mounting portion near the end of the gantry, and the aforementioned lateral movement guide wheels 22132 and lateral movement bearing wheels 22133 are provided on the lateral movement guide assembly mounting portion. Such as lateral movement guide wheels 22132 include two riding on lateral movement hard rail 22131, one of which acts as a reference wheel and the other as an adjustment wheel. In response to the direction of movement of the traversing assembly, the roll direction of the traversing weight wheels 22133 coincides with the traversing direction (the length direction of the gantry), i.e., the axis of the traversing guide wheels 22132 (vertical direction) is generally perpendicular to the axis of the traversing weight wheels 22133 (horizontal direction). To better ensure bearing reliability, a plurality of lateral movement load bearing wheels 22133 may be provided on the lateral movement guide assembly mounting portion. Illustratively, one or a set (e.g., a pair) of laterally displaced load bearing wheels 22133 are provided at each of the four corners of the laterally displaced guide assembly mounting portion. Taking the example of the transverse moving weight wheels 22133 including a pair, the pair of transverse moving weight wheels 22133 may be aligned in the width direction or the length direction of the gantry.

Longitudinal movement component of movement component

In one possible embodiment, the longitudinal movement assembly 222 includes a longitudinal movement slide 2221 (located between the primary and secondary ends and slidably coupled to the slide), a longitudinal movement drive component, in this example a longitudinal movement drive motor 2222, and a longitudinal movement transmission mechanism, in this example a longitudinal movement rack and pinion mechanism 2223, which may also be a motor, a motor-driven reducer, or other drive/drive mechanism, and may also be a sprocket-and-chain mechanism, a lead screw-nut mechanism, or the like. The longitudinal movement rack and pinion mechanism comprises a longitudinal movement gear and a longitudinal movement rack, wherein the longitudinal movement gear is in driving connection with a longitudinal movement driving motor, the longitudinal movement rack is arranged on a longitudinal movement sliding seat, and the longitudinal movement driving motor is arranged on the sliding table and accordingly enables the sliding table to generate relative movement with the longitudinal movement sliding seat along the vertical direction. Under the limitation of the transverse moving assembly, the sliding table cannot move along the vertical direction, so that the sliding seat can move along the vertical direction by moving longitudinally. Based on the above, the longitudinally moving driving motor can drive the longitudinally moving sliding seat and the clamping jaw assembly arranged on the longitudinally moving sliding seat to move along the vertical direction through the longitudinally moving gear rack mechanism. Therefore, accurate movement of the sliding table in the longitudinal movement direction can be realized through servo control of the longitudinal movement driving motor. Such a structure can effectively save the layout space of the longitudinal movement assembly including the longitudinal movement rack and pinion mechanism by transmitting the power from the longitudinal movement drive motor through the engagement of the longitudinal movement rack and pinion.

In one possible embodiment, a longitudinal movement guide assembly is further provided on the longitudinal movement slide 2221, for example, the longitudinal movement guide assembly includes a longitudinal movement linear guide 2224 to ensure stability of the longitudinal movement process. If the cross section of the longitudinally moving sliding seat is approximately rectangular, a longitudinally moving linear guide rail is respectively arranged at a position close to each edge of the rectangle, so that the four longitudinally moving linear guide rails are used, and the sliding table can obtain better stability when moving along the longitudinal moving direction relative to the longitudinally moving sliding seat. Wherein four longitudinally movable linear guides are located on three of the faces of the longitudinally movable carriage to prevent over-positioning problems. The longitudinally movable rack is fixedly arranged between the two longitudinally movable linear guide rails.

In one possible embodiment, the longitudinal movement driving motor is disposed on the sliding table 223 in such a manner that a longitudinal movement driving motor installation component 2231 is disposed on the sliding table 223, for example, the longitudinal movement driving motor installation component is an annular supporting structure capable of being sleeved on the outer side of the longitudinal movement sliding seat, for example, a guide groove capable of being matched with the two pairs of longitudinal movement linear guide rails is disposed on the inner side of the annular supporting structure, and the longitudinal movement driving motor is disposed on the longitudinal movement driving motor installation frame. If the annular supporting structure includes a vertical portion and a lateral portion extending outward from the bottom of the vertical portion, the lateral portion is fixed to the upper surface of the sliding table 223 by means of a fastener such as a screw, for example, a reinforcing structure such as a reinforcing plate may be added between the vertical portion and the lateral portion in order to secure the strength of the annular supporting structure. It is obvious that a person skilled in the art can determine the structural form of the longitudinally moving driving motor mounting part and the assembly relation with the sliding table and the longitudinally moving driving motor according to actual requirements, and the longitudinally moving driving motor mounting part can be a supporting frame, a U-shaped structure with one side in the circumferential direction being an open side, and the like.

[ Clamping jaw Assembly ]

In one possible embodiment, the jaw assembly 23 includes a fixed jaw assembly 231 and an adjusting jaw assembly 232 disposed along the axial direction of the silicon rod, the main functions of the jaw assembly including:

1) The silicon rod may be clamped in two poses, as in this example, the jaw assembly may be used to clamp the silicon rod in a 45 ° face V-clamp and in a 0 ° face conventional clamp. If the V-shaped clamping is carried out on the silicon rod during feeding, the conventional vertical clamping is carried out on the silicon rod during discharging. Obviously, the clamping modes can be exchanged or any one of the same clamping modes can be adopted according to actual requirements.

2) The fixed clamping jaw assembly and the adjusting clamping jaw assembly can generate relative motion along the axial direction of the silicon rod so as to realize reliable clamping of the silicon rods with different sizes. The relative motion therein includes two cases:

One is that a single action of the adjustment jaw assembly (the fixed jaw assembly being in a first state in which the fixed jaw assembly is relatively stationary and only the adjustment jaw assembly is moved closer to/further from the fixed jaw assembly) can be achieved by the switching assembly.

The other is linkage between the fixed clamping jaw assembly and the adjusting clamping jaw assembly (the fixed clamping jaw assembly is in a second state, and the fixed clamping jaw assembly and the adjusting clamping jaw assembly are relatively static and can synchronously generate motion along the axial direction of the silicon rod).

3) The fine adjustment of the axis of the silicon rod can be realized by adjusting the internal adjustment of the clamping jaw assembly, so that the accurate clamping requirement of the silicon rod (wool rod) from the feeding assembly is better met, and the feeding deviation of the wool rod can be effectively compensated.

4) The center alignment of the silicon rod can be better realized in a 45-degree material grabbing mode from the feeding assembly. Specifically, in the process of grabbing and clamping the silicon rod at 45 degrees in the feeding process, the function of aligning the silicon rod is achieved, so that a structure corresponding to alignment is not required to be additionally arranged, an alignment step is omitted, and on the premise that the reliability of the position and the posture of the silicon rod can be guaranteed, the structure is simplified, and the operation efficiency is improved.

In one possible embodiment, the clamping jaw assembly 23 mainly includes a clamping jaw base (such as a fixing seat, etc.) 230, and a fixing clamping jaw assembly 231 and an adjusting clamping jaw assembly 232 are disposed on the clamping jaw base, and the fixing clamping jaw assembly and the adjusting clamping jaw assembly can cooperate to form a clamping space for clamping the silicon rod. Wherein the jaw base is provided with a jaw traverse mechanism 233 by means of which the fixed jaw assembly and the adjusting jaw assembly can be brought into relative movement towards/away from each other.

In one possible embodiment, the jaw lateral movement mechanism 233 includes a jaw lateral movement drive motor 2331 and a jaw lateral movement gear chain mechanism 2332, the jaw lateral movement drive motor is in driving connection with a gear of the jaw lateral movement gear chain mechanism to drive a chain meshed with the gear to move along an axis direction thereof, the chain is provided with a first mounting position 2331 and a second mounting position 2332 along an axis thereof, the fixed jaw assembly can be arranged at the first mounting position, and the adjustment jaw assembly is fixedly arranged at the second mounting position and can thus move along with the movement of the chain. The first/second mounting location includes a mounting base fixed to the chain, and the mounting bases corresponding to the first/second mounting location may be the same or different, and it is apparent to those skilled in the art that the specific structural form of the mounting base and the manner and location of fixing to the chain may be flexibly selected according to actual requirements.

In one possible embodiment, the jaw traversing mechanism is provided with a set of switch assemblies 2334 at positions corresponding to the first mounting locations, by means of which the fixed jaw assembly can be switched to the first state, in particular in a state of being fixed to the first mounting locations, in case it is desired that the fixed jaw assembly moves together with the adjusting jaw assembly. The fixed jaw assembly may be switched to the second state by means of the switching assembly without the fixed jaw assembly moving with the adjusting jaw assembly, in particular, with the fixed jaw assembly in a state in which the fixed constraint relationship with the first mounting position is released. In this way, through the cooperation of switching component, clamping jaw lateral shifting gear chain mechanism and set up in clamping jaw lateral shifting gear chain mechanism's mount pad for fixed clamping jaw subassembly can switch between first state and second state, based on this, hopefully makes fixed clamping jaw subassembly and adjustment clamping jaw subassembly can satisfy the demand of silicon rod in the transportation process better, like to the silicon rod of same size, can adjust clamping position in a flexible way according to actual conditions. For silicon rods of different sizes, a clamping position more adapted to the silicon rod can be found.

In one possible embodiment, the switching assembly 2334 includes a switching driving component, such as in this example, the switching driving component is an air cylinder 2341, and the power output end of the air cylinder is connected with the pressing block 23342, so, in the case that the power output end of the air cylinder is pushed out downwards, the pressing block can be pushed to move downwards, so that the pressing block is abutted to the first mounting position or is abutted to the fixed clamping jaw assembly on the first mounting position (directly abutted or indirectly abutted to the fixed clamping jaw assembly), and the fixed clamping jaw assembly is locked with the chain. Thus, the fixed clamping jaw assembly and the adjusting clamping jaw assembly can move along with the movement of the chain. Correspondingly, when the position of the fixed clamping jaw assembly is required to be relatively fixed (the fixed clamping jaw assembly does not move along with the movement of the chain), the adjusting clamping jaw assembly can approach to the fixed clamping jaw assembly along with the movement of the chain, and the power output end of the air cylinder is retracted upwards, so that the compression block is separated from the first mounting position or the fixed clamping jaw assembly arranged on the first mounting position. As in the present example, the switch assembly 2334 includes a mounting rack 23343 disposed at a position corresponding to the first mounting position of the fixed jaw assembly, and the mounting seat, the air cylinder, the pressing block and the fixed jaw assembly corresponding to the first mounting position are disposed on the mounting rack, such as a reset structure including a reset spring 23344 may be disposed between the mounting rack and the transfer mechanism, so that after the fixed jaw assembly is separated from the chain, the structure including the fixed jaw assembly disposed on the mounting rack returns to the set position of the transfer mechanism under the action of the reset spring. For example, the reset structure can be other structural forms such as a power cylinder, a linear module comprising a motor and the like which can provide a pulling force along a set direction, and obviously, on the premise of no interference, a person skilled in the art can determine the specific orientation of the transfer mechanism corresponding to the returned set position according to the actual situation.

It will be appreciated that the above structure is only one exemplary description of the switching assembly, and those skilled in the art may determine the structural form, the first state, the second state, the switching manner therebetween, and the like of the switching assembly according to actual requirements. For example, the constraint relation between the pressing block and the first mounting position can be changed from abutting to other matching relations such as splicing, meshing, joggling and the like, and the switching driving component can be changed from a cylinder to other power cylinders such as a hydraulic cylinder, an electric cylinder and the like or a linear module with the same function. Besides the assembly of the air cylinder and the compression block, any type of clutch device can be reasonably modified to be used as the switching assembly of the utility model.

Fixed jaw assembly of jaw assembly (first jaw assembly, enabling horizontal fine tuning but not longitudinal fine tuning for silicon rod axis)

In one possible embodiment, the stationary jaw assembly 231 basically includes a stationary jaw base 2311 (e.g., a connection base, etc.), a stationary jaw drive member, a stationary jaw drive mechanism and a stationary jaw set. In this example, the fixed jaw driving component is a fixed jaw driving motor 2312, the fixed jaw transmission mechanism is a fixed jaw screw nut mechanism 2313, where the fixed jaw group includes a first fixed jaw 23141 and a second fixed jaw 23142, such as a connecting seat with a fixed jaw base body having a substantially U-shaped structure, a screw rod of the fixed jaw screw nut mechanism is disposed between two vertical portions of the connecting seat, the fixed jaw driving motor is disposed on a transverse portion of the connecting seat, two threaded sections with opposite rotation directions are disposed on the screw rod of the fixed jaw screw nut mechanism, and the first fixed jaw and the second fixed jaw are respectively fixedly connected to two nuts of the fixed jaw screw nut mechanism that are matched with the two threaded sections. Based on the above, the fixed clamping jaw driving motor drives the screw rod in the fixed clamping jaw screw nut mechanism to rotate, so that the (first and second) fixed clamping jaws can move in the directions approaching to/separating from each other at the same time, and the centering and clamping function of the silicon rod is completed. In addition, when the feeding clamping is completed through the fixed clamping jaw driving motor, the section size of the silicon rod can be directly calculated according to the clamping jaw driving motor, and the beat of the feeding transferring link is saved.

It will be appreciated that the fixed jaw drive motor and fixed jaw lead screw nut mechanism are merely exemplary descriptions of one manner of effecting relative movement between the first/second fixed jaws, and that one skilled in the art may make a reasonable selection of fixed jaw drive components/transmissions based on actual needs, such as changing the fixed jaw drive motor to a rotational module capable of effecting movement without changing the drive transmission form, changing the fixed jaw lead screw nut mechanism to a rack and pinion pair, configuring a set of fixed jaw lead screw nut mechanisms for each of the two fixed jaws (the two fixed jaws may be moved relatively independently), etc. In the case of adjustment of the drive transmission form, the fixed jaw drive motor can be changed to a power cylinder (such as a cylinder, an electric cylinder, a hydraulic cylinder and the like) and other linear modules, and the fixed jaw screw nut mechanism can be correspondingly changed to other component forms capable of realizing corresponding transmission, and the like.

In one possible embodiment, the first and second fixing jaws 23141 and 23142 have first and second clamping positions 23151 and 23152, respectively, on clamping portions facing each other and thus enable a first clamping space to be formed therebetween by a pair of first clamping positions and a second clamping space to be formed therebetween by a pair of second clamping positions, wherein the first clamping space is capable of clamping a silicon rod of 45 ° face (first posture, V-shaped clamping, or inclined clamping), and the second clamping space is capable of clamping a silicon rod of 0 ° face (second posture, vertical clamping, or 0 ° conventional clamping). Therefore, the clamping of the silicon rod with two postures can be realized through the same set of fixed clamping jaw assembly. In this example, the first clamping space is mainly used for clamping a silicon rod (blank rod) before grinding operation in a V-shaped clamping manner, and the second clamping space is mainly used for clamping a silicon rod (finished rod) after grinding operation in a vertical clamping manner, and the first clamping space is located below the second clamping space.

In the case where vertical clamping is required, the two fixed jaws are moved close to each other until they come into close abutment with the sides of the silicon rod to clamp the silicon rod. In the case of silicon rods of the same specification (size), in the case where V-shaped clamping is required, it is necessary to move the two fixed jaws further toward each other so that the silicon rods can be clamped in the V-shaped clamping. Compared with the vertical clamping mode, the V-shaped clamping mode can achieve coincidence of the diagonal line of the silicon rod and the center of the first clamping space, so that under the condition of V-shaped clamping, the centering operation of the silicon rod can be completed in the clamping process. In addition, the cross-sectional dimension of the silicon rod can be accurately calculated according to the opening and closing distance between the two fixed clamping jaws.

In one possible embodiment, the fixed jaw assembly 231 further comprises a falling prevention assembly 2316, so that the falling prevention assembly is added, because the clamping stability of the silicon rod is mainly ensured by virtue of the friction force between the pair of vertical clamping and attaching surfaces corresponding to the second clamping space and the pair of vertical side surfaces of the silicon rod in the case of vertically clamping the silicon rod with the 0 DEG surface of the fixed jaw assembly 231, and when the silicon rod is fed, for example, the vertical clamping is adopted, for example, because the surface of the silicon rod after being processed by grinding operation is very smooth (the friction coefficient is very small), therefore, if the friction force between the clamping and attaching surfaces and the side surfaces of the silicon rod is insufficient, the risk of sliding the rod or even falling off the rod may exist. Therefore, through the cooperation of the second clamping space and the anti-falling assembly, the clamping reliability under the vertical clamping condition is ensured.

In one possible embodiment, referring to the positional relationship in which the first holding space is located below the second holding space in this example, the fall arrest assembly may be disposed at a position where the two fixed jaws are located close to below. Therefore, when the silicon rod is clamped in a vertical clamping mode, a certain auxiliary supporting force can be provided for the silicon rod through the anti-falling assembly, so that the silicon rod can be reliably clamped in the second clamping space, such as the anti-falling assembly can be used for supporting the clamping reliability of the clamping jaw assembly during the process of clamping the silicon rod in the vertical clamping mode.

In one possible embodiment, the fall arrest assembly 2316 includes a pair of pivotally disposed fall arrest hooks 23161 corresponding to the pair of stationary jaws, such that the fall arrest hooks can provide a certain supplemental compression and/or holding force by rotating the fall arrest hooks when the silicon rod is clamped in a vertical grip by the pair of stationary jaws. Illustratively, the fall arrest unhook includes first and second angularly disposed hooks 231611 and 231612, the junction of the first and second hooks 231611 and 231612 being pivotally connected to the respective first or second fixed jaws. When the silicon rod is clamped by the pair of fixing clamping jaws in a vertical clamping manner, the anti-falling unhook is rotated relative to the corresponding first fixing clamping jaw or second fixing clamping jaw to a state that the end of the first hook portion is abutted to the side wall of the silicon rod, and the chamfer surface (the narrow surface formed after chamfering the edge) between the bottom surface and the side surface of the bar is abutted to the wall of the second hook portion. If the second hook is substantially strip-shaped, a wall is understood to mean that the strip-shaped structure has a narrower face (or line) in the direction of the chamfer between the bottom and side faces facing the bar. In the case where the wall portion of the second hook portion abuts against the chamfer between the bottom surface and the side surface of the bar, the pressure-receiving area is substantially in line contact or line contact having a width (which may be referred to as narrow-surface contact), so that the second hook portion can be used to hook the lower portion of the silicon rod in an auxiliary manner. Through the dual guarantee of lateral part increase clamp force and bottom increase bearing force, can guarantee the centre gripping stability of silicon rod when being by vertical centre gripping effectively to reliability and security when snatching the operation through the second clamping position of fixed clamping jaw subassembly have been guaranteed effectively.

In the blanking process, vertical clamping is taken as an example, and because the silicon rod clamped at the moment is a finished rod with the surface precision reaching the standard through grinding operation, for example, in order to prevent the side surface and chamfer surface of the finished rod from being scratched and other problems, buffer structures such as a polyurethane layer and the like can be arranged at least at the end part of the first hook part and the side part of the second hook part.

It is obvious that the structural form, the number and the pivoting arrangement of the anti-falling unhooking device are only exemplary, and a person skilled in the art can flexibly change the anti-falling unhooking device according to actual requirements, for example, the end part of the first hook part is provided with a multi-claw structure (similar to an octopus), a deformable structure (such as silica gel and the like) to better realize the abutting of the anti-falling unhooking device and a silicon rod, the side part of the second hook part is outwards concave, and the end part of the second hook part is provided with a structure similar to the first unhooking device, so that a bearing force can be provided in a double-end supporting manner, the anti-falling unhooking device only comprises the first hook part or the second hook part, the angle between the first hook part and the second hook part can be fixed or adjusted, and the anti-falling unhooking hook can be pivoted to the first fixed claw or the second fixed claw, and can be arranged at any reasonable position capable of realizing the rotation of the anti-falling unhooking device without interference and without interference of other parts.

In one possible embodiment, the fall arrest assembly 2316 further includes a fall arrest reset assembly 23162, such as a reset spring, for example, one end of the reset spring is disposed at the corresponding first fixed jaw or second fixed jaw, and the other end is connected to a reasonable position of the fall arrest unhooking hook, such as the outer side of the second hook portion, so that the fall arrest unhooking hook can be in a state of not interfering with the clamping operation of the first clamping space under the action of the reset spring without operating the fall arrest assembly. Obviously, besides the return spring, any method can be adopted to ensure the position reliability of the anti-falling unhooking hook in the non-working state, such as various types of springs, structural components capable of providing tensile force, and the like, and the position reliability of the anti-falling unhooking hook in the non-working state can be realized by extending a protrusion on the fixed clamping jaw.

As in the case of a 0 deg. conventional clamping of a silicon rod, the silicon rod is already in a horizontal position through the previous process, at which time the first holding jaw 23141 and the second holding jaw 23142 are first brought to the desired clamping position by axial movement (synchronous movement or relative movement) depending on the size of the silicon rod. Thereafter, the pair of first holding jaw 23141 and second holding jaw 23142 are brought close to each other to clamp the silicon rod. After the silicon rod is clamped, the anti-falling assembly is rotated by a certain angle, so that the first hook part and the second hook part are in a working state, and the operation of conventional clamping at 0 DEG can be completed. When blanking is required, the pair of clamping jaws of the first fixed clamping jaw 23141 and the second fixed clamping jaw 23142 move to two sides to loosen the silicon rod, and the pair of anti-falling unhooks return to the initial position without interference with the clamping jaw assembly under the action of the anti-falling reset assembly.

In addition, a pair of rotatable anti-falling unhook is just an exemplary description of anti-falling components, and a person skilled in the art can select any reasonable structural form according to actual requirements to ensure the clamping stability of the second clamping space, such as an abutting structure capable of moving in a telescopic manner along the clamping direction is arranged on two clamping surfaces of the second clamping space, and a tightening structure capable of providing upward bearing force for the silicon rod is arranged outside.

Furthermore, although the present example is described as having the fall arrest assembly assist only when the second clamping space is in the operative state, it should be apparent that the fall arrest assembly may also be made to provide some assist when necessary in the case where the first clamping space is in the operative state.

Adjusting jaw assembly of jaw assembly (second jaw assembly, which enables horizontal and longitudinal fine adjustments to the axis of the silicon rod), longitudinal fine adjustments to the axis of the silicon rod are achieved by the first adjusting assembly

In one possible embodiment, adjustment jaw assembly 232 generally includes an adjustment jaw base 232 (e.g., a connection block, etc.) and an adjustment jaw set disposed on the adjustment jaw base. The adjusting jaw set includes a first adjusting jaw 23221 and a second adjusting jaw 23222, which are similar to the first/second fixing jaw in structure and function in this example, mainly form a first clamping space and a second clamping space through cooperation between a pair of jaws and complete V-shaped clamping and vertical clamping of the silicon rod.

The aforementioned fixed jaw set differs in that the adjusting jaw assembly further comprises a first adjusting assembly (longitudinal fine adjustment) for effecting movement of the two adjusting jaws in the vertical direction.

In one possible embodiment, the first adjusting jaw and the second adjusting jaw are provided with a set of first adjusting assemblies by means of which a movement of the first/second adjusting jaw in its longitudinal direction (vertical direction) can be achieved.

In one possible embodiment, the first adjustment assembly includes a second adjustment driving motor 23231 (a first adjustment driving component), a first adjustment cam 23232 (a first adjustment transmission mechanism) and a first adjustment guiding structure 23233, a connecting bracket of the adjustment jaw base body has a reserved space, a power output shaft of the first adjustment driving motor is in driving connection with the first adjustment cam, the cam is freely accommodated in the reserved space and is abutted to the connecting bracket (such as in line contact or narrow surface contact), and the first adjustment guiding structure is disposed on the bracket main body of the adjustment jaw base body and only allows the first/second adjustment jaw to move along the vertical direction. In this example, the reserved space is a round hole, the first adjusting cam is abutted with the connecting support corresponding to the position of the round hole near the top, if the first adjusting guiding structure is a first adjusting linear sliding rail, a groove-shaped structure matched with the first adjusting linear sliding rail is correspondingly arranged on the connecting support of the adjusting clamping jaw base body, if the reserved space can also be in other structural forms such as a square hole or a groove with an open bottom side, and the first adjusting guiding structure can also be in other structures such as an optical axis. In this way, under the driving action of the first adjusting driving motor, the first adjusting cam is abutted with the position, close to the top, of the reserved space, so that the connecting support of the adjusting clamping jaw base body is driven to move in the vertical direction, and therefore the first adjusting clamping jaw and the second adjusting clamping jaw are driven to move (the first adjusting clamping jaw is connected with the first adjusting linear guide rail of the connecting support arranged on the adjusting clamping jaw base body), and meanwhile, due to the constraint of the first adjusting guide structure, the first adjusting clamping jaw and the second adjusting clamping jaw can achieve fine adjustment of the position of the first adjusting clamping jaw and the second adjusting clamping jaw along the longitudinal direction.

Therefore, when the axis of the silicon rod in the clamping state is slightly deviated from the horizontal direction (an included angle is formed between the axis of the silicon rod and the horizontal plane), the two adjusting jaws of the adjusting jaw assembly can be driven by the second adjusting assembly to synchronously move along the longitudinal direction, so that a certain height difference is generated between the clamping position of the fixed jaw assembly and the clamping position corresponding to the adjusting jaw assembly, and the deviation of the central axis relative to the horizontal plane can be effectively restrained.

It will be appreciated that the foregoing description of the configuration of the first adjustment assembly is merely exemplary, and that a person skilled in the art may make flexible modifications thereto, such as modification of the cam to an eccentric shaft or other eccentric configuration, according to actual needs. Further, one first adjusting member may be provided for each of the first and second adjusting jaws, or the first adjusting members of both may be partially shared, or the like. And, can also adopt other drive transmission forms to realize under the prerequisite that can realize the lifting of direction of height, can change driving motor into power jar, sharp module, rotation module etc. for example, can change the cam into screw nut mechanism, worm gear pair, rack and pinion mechanism, sprocket chain mechanism etc.. The power cylinder drives a pair of connecting blocks with inclined planes to move, lifting wheels capable of rolling along the inclined planes of the connecting blocks are respectively arranged on the inclined planes of the connecting blocks, and the wheel shafts of the lifting wheels are arranged on the connecting support for adjusting the clamping jaw base body.

In one possible embodiment, the clamping jaw assembly 23 further comprises a second adjusting assembly based on the fixed clamping jaw assembly and the adjusting clamping jaw assembly, wherein the fixed clamping jaw assembly and the adjusting clamping jaw assembly share a set of second adjusting assemblies, and the second adjusting assembly has the function of enabling the axis of the silicon rod to coincide with the ideal position by integrally rotating the silicon rod and related structures such as the fixed clamping jaw assembly, the adjusting clamping jaw assembly and the like when the axis of the silicon rod is offset left and right in a horizontal plane. Therefore, the second adjusting assembly ensures the clamping precision of the axis of the silicon rod in the horizontal plane mainly by carrying out integral transverse micro-rotation on the fixed clamping jaw assembly and the adjusting clamping jaw assembly.

In one possible embodiment, the second adjustment assembly includes a second adjustment drive component, such as a second adjustment drive motor 23241 in this example, and a second adjustment drive mechanism, including a second adjustment cam 23242, pivotally coupled between the bottom of the longitudinally movable slide 2221 of the longitudinally movable assembly 222 and the jaw base 230 of the jaw assembly 23, such that the position of the silicon rod axis sandwiched between the fixed and adjustable jaw assemblies in the horizontal plane can be fine-tuned by a small amount of rotation of the jaw base 230 and the fixed/adjustable jaw assemblies disposed thereon relative to the longitudinally movable slide 2221.

In one possible embodiment, the longitudinally movable slide 2221 is pivotally connected to the jaw base 230 by a second adjustment center of rotation assembly, such as in this example, comprising a cross roller bearing 23243, the bottom of the longitudinally movable slide 2221 being provided with a second adjustment link member 22211, such as a second adjustment link member being generally a web, the cross roller bearing 23243 being disposed between the web and the jaw base, a second adjustment drive motor 23241 being secured to a side of the jaw base 230 corresponding to the adjustment jaw assembly 232, a second adjustment aperture 222111 being provided on the web that is engageable with a second adjustment cam, the outer edge of the second adjustment cam being capable of abutting against the aperture wall of the second adjustment aperture. In this way, when the axis of the silicon rod has a certain deviation in the horizontal plane, the second adjustment driving motor 23241 drives the second adjustment cam to rotate in the second adjustment hole, and the longitudinal moving slide 2221 cannot rotate under the limitation of the sliding table, so that the micro-rotation of the clamping jaw base 230 relative to the longitudinal moving slide 2221 can be realized. Based on the micro-rotation, the pose of the axis of the silicon rod in the horizontal plane can be finely adjusted, and on the basis, the clamping precision of the axis of the silicon rod in the horizontal plane is hopefully realized.

It should be understood that the foregoing structural form of the second adjusting assembly is merely an exemplary description, and those skilled in the art may flexibly change the structural form according to actual needs, for example, the second adjusting transmission mechanism may be any other eccentric structure, or may be any structure capable of realizing pivot connection, such as a screw-nut mechanism, a worm gear mechanism, a rack-and-pinion mechanism, a sprocket-and-chain mechanism, etc., the second adjusting driving component may be any form of rotation module, a power cylinder (such as an air cylinder, a hydraulic cylinder, an electric cylinder, etc.), any form of linear module, etc., and the second adjusting rotation center component may be any structure capable of realizing pivot connection, such as a rotating shaft, a turntable, etc.

Furthermore, although in the present example the second adjustment drive motor and the second adjustment cam are provided on the side close to the adjustment jaw assembly, it is obvious that the second adjustment drive/transmission structure may be provided on the side close to the fixed jaw assembly or on both sides. Of course, in the case that the pivoting is possible, the second adjustment driving/transmitting structure may be directly disposed at a position close to the second adjustment rotation center assembly, for example, the second adjustment driving/transmitting structure is a rotation structure/module, and the second adjustment rotation structure/module directly drives the second adjustment rotation center assembly to rotate.

It can be seen that in a preferred embodiment of the present utility model, by the arrangement of the aforementioned first adjustment assembly, a longitudinal fine adjustment of the axis of the silicon rod in the vertical direction can be achieved. Through the setting of second adjustment subassembly, clamping jaw base member and set up the whole micro-rotation of fixed/adjustment clamping jaw subassembly on the clamping jaw base member, can realize the fine setting of the axis position of silicon rod in the horizontal plane. Specifically, if the central axis of the silicon rod is offset in the vertical direction when the silicon rod is clamped, the silicon rod can be realized by driving the first adjusting cam to rotate relative to the sliding table through the first adjusting assembly. If the central axis of the silicon rod is deviated in the horizontal plane when the silicon rod is clamped, the silicon rod can be realized by driving the second adjusting cam to rotate relative to the sliding table through the second adjusting assembly. The synchronous movement of the silicon rod toward the direction capable of suppressing the offset ensures the positional accuracy of the silicon rod in the horizontal direction.

It should be noted that, in the description of the present embodiment, the adjusting jaw assembly is configured with the first adjusting assembly alone, the fixing jaw assembly and the adjusting jaw assembly share the second adjusting assembly, and since the second adjusting driving component/driving mechanism of the second adjusting assembly is configured at a side close to the adjusting jaw, for convenience of description, the jaw assembly for implementing the clamping of the silicon rod will be described after being divided into the fixing jaw assembly and the adjusting jaw assembly. In practice, however, the fixed jaw assembly also participates in fine tuning of the silicon rod axis in the horizontal plane. The adjusting object of the first adjusting component is an adjusting clamping jaw component, and the adjusting object pair of the second adjusting component comprises a fixed clamping jaw component, an adjusting clamping jaw component, a clamping jaw base body and the like.

In one possible implementation mode, the first adjusting clamping jaw and the second adjusting clamping jaw are respectively provided with a correlation photoelectric switch at two sides along the axial direction of the silicon rod, and the two correlation photoelectric switches are mainly used for measuring the length of the silicon rod before feeding. The determination of the length of the silicon rod will be described below with respect to a pair of opposed photoelectric switches (referred to as a first pair of photoelectric switches and a second pair of photoelectric switches, respectively) disposed in the first adjustment jaw.

The process of clamping the silicon rod through the fixed clamping jaw assembly and the adjusting clamping jaw assembly is generally that the fixed clamping jaw assembly clamps one side of the silicon rod, and then the adjusting clamping jaw assembly starts from an initial clamping position of the silicon rod and moves along the length direction of the silicon rod. The distance from the initial clamping position of the known adjusting clamping jaw assembly to the front end (left side) of the silicon rod is a, the distance from the first pair of photoelectric switches on the left side to the center of the first adjusting clamping jaw is n, and the distance from the second pair of photoelectric switches on the right side to the center of the first adjusting clamping jaw is m.

Based on this, for a silicon rod with a larger length, the first/second correlation photoelectric switch can receive signals, so that the first/second adjustment clamping jaw can move along the axis direction of the silicon rod until the second correlation photoelectric switch on the right side cannot receive signals, and at this time, the length l=a+m+x of the silicon rod can be determined according to the detected distance x of the first/second adjustment clamping jaw moving rightwards. For a silicon rod with a smaller length, the first opposite-shooting photoelectric switch on the left can receive signals, the second opposite-shooting photoelectric switch on the right can not receive signals, and the first/second adjusting clamping jaw can move along the axis direction of the silicon rod until the first opposite-shooting photoelectric switch on the left can not receive signals. At this time, the length l=a+x-n of the silicon rod can be determined according to the detected distance x by which the first/second adjustment jaw moves rightward.

Based on the above structure, in one possible embodiment, for any one grinding unit in the grinding machine production line of the present utility model, the main operation of the transfer mechanism 2 includes four steps of V-shaped grabbing wool stick, V-shaped feeding, 0 ° grabbing finished product stick, and 0 ° placing finished product stick (blanking).

1. V-shaped grabbing wool stick:

In one possible embodiment, in the case that the transfer mechanism is ready to perform feeding clamping on the wool rod to be ground, the sliding table moves horizontally along the portal frame by means of the transverse moving component, so that the clamping jaw component arranged on the sliding table is driven to move above the feeding component, the clamping jaw component moves downwards to a feeding clamping position capable of grabbing the V-shaped wool rod placed on the feeding component by means of the longitudinal moving component, and the clamping jaw component is fixed/adjusted to release the first clamping space so as to smoothly clamp the silicon rod on the basis.

The conventional clamping process is that the two fixing clamping jaws of the fixing clamping jaw assembly are firstly used for clamping the silicon rod by using the first clamping space corresponding to the V-shaped clamping, and the silicon rod can be centered while being clamped because the first clamping space and the silicon rod at the moment have the matched V-shaped posture. In the case where the clamping operation of the fixed jaw assembly has been completed, the adjusting jaw assembly is moved in the length direction of the silicon rod (the fixed jaw assembly is brought into the second state by means of the switching assembly) to the set position and the bar is clamped by bringing the two adjusting jaws close to each other. In this process, the length of the silicon rod can be measured by two pairs of correlation photoelectric switches arranged on the adjusting clamping jaw assembly.

In the case that the posture of the silicon rod in the clamping state is slightly deviated, the position of the silicon rod can be adjusted by adjusting the clamping jaw assembly. In particular, if there is a certain displacement (lateral deviation) between the central axis of the silicon rod and the ideal position (vertical plane) when it is clamped, such deviation can be suppressed/eliminated by the first adjustment assembly. And if the silicon rod is clamped with a certain angle (longitudinal deviation) between its central axis and the horizontal plane, such deviation can be suppressed/eliminated by the second adjustment assembly.

2. V-shaped feeding:

After the silicon rod is clamped, the longitudinal moving assembly drives the clamping jaw assembly clamping the silicon rod to vertically move upwards, and the sliding table comprising the longitudinal moving assembly and the clamping jaw assembly moves along the portal frame through the transverse moving assembly so as to reach the position above the clamping position corresponding to the grinding assembly. On the basis, the clamping jaw assembly clamping the silicon rod vertically moves downwards through the longitudinal moving assembly to reach the clamping position of the grinding assembly. When the clamping assembly of the grinding assembly starts to clamp the silicon rod, potential energy of the clamping jaw assembly is removed, so that the clamping jaw assembly can move along with the movement of the silicon rod. After the clamping assembly of the grinding assembly clamps the silicon rod steady, the fixed and adjusting jaw assemblies of the jaw assembly are released from each other, thereby releasing the first clamping space (the jaw assemblies release the silicon rod).

After the clamping jaw assembly releases the constraint on the silicon rod, the clamping jaw assembly can be driven to a certain position which does not interfere with grinding through the transverse moving assembly and the longitudinal moving assembly, for example, the clamping jaw assembly can be a position corresponding to other grinding stations or a certain designated position (such as a position close to the end of a portal frame or a position still located at the current grinding station but not interfering with grinding operation (such as a waiting grinding position) on the silicon rod through the grinding assembly, and the grinding operation for the side and the edge can be performed on the silicon rod through the grinding assembly.

3. 0 Degree grabbing finished product bar:

After the grinding operation of the silicon rod is finished, the finished product rod with the surface precision reaching the standard can be obtained. At this time, (the second clamping space of) the clamping jaw assembly is moved to the post-grinding clamping position of the silicon rod by the lateral movement assembly and the longitudinal movement assembly. On this basis, the fixed jaw assembly and the adjusting jaw assembly of the jaw assembly are brought close to each other and grip the finished rod in a conventional clamping manner of 0 °. At this time, the two pairs of falling-preventing unhooks of the falling-preventing assembly are pivoted to a posture capable of providing auxiliary pressing force/supporting force for the finished product rod so as to prevent the phenomenon that the silicon rod with the standard surface precision is like a sliding rod, even a unhooking rod and the like.

After the silicon rod is grabbed, the clamping jaw assembly moves vertically upwards through the longitudinal moving assembly, and the clamping jaw assembly comprising the longitudinal moving assembly and the sliding table moves to a blanking position corresponding to the blanking assembly through the transverse moving assembly.

4. 0-Degree blanking:

After the clamping jaw assembly moves vertically downwards to a discharging position corresponding to the discharging assembly through the longitudinal moving assembly, the fixed clamping jaw assembly and the adjusting clamping jaw assembly of the clamping jaw assembly are loosened, and the two pairs of anti-falling unhooking hooks on the adjusting clamping jaw assembly are pivoted and loosened, so that the second clamping space is released. At this time, the silicon rod can fall onto the blanking table of the blanking assembly, so that one complete operation is completed. Such as may be engaged by an AGV or the like with the blanking assembly to transport the finished rod to a location such as a station of a slicer corresponding to a downstream process.

And then, the clamping jaw assembly comprising the sliding table and the longitudinal moving assembly can be moved to the feeding position of the grinding production line again, and the second feeding grabbing is prepared.

In a specific embodiment, in the grinding machine production line of the present utility model, the operation flow for any grinding operation generally includes the following steps:

S1, placing a silicon rod (a wool rod to be processed) on a feeding assembly.

S2, starting the transverse moving assembly, and transversely transferring the clamping jaw assembly to a feeding position corresponding to the feeding assembly.

S3, the fixed clamping jaw assembly and the adjusting clamping jaw assembly of the clamping jaw assembly are opened to a position capable of freely accommodating the silicon rod, and a pair of clamping jaws of the fixed clamping jaw assembly and the adjusting clamping jaw assembly are opened to the maximum position.

S4, enabling the clamping jaw assembly to clamp the silicon rod tightly. During this time, in order to secure the clamping accuracy, it may be necessary to fine-tune the posture of the silicon rod by the first/second adjustment assembly.

S5, starting the longitudinal moving assembly, and enabling the clamping jaw assembly to upwards grab the silicon rod.

S6, starting the transverse moving assembly, and transversely moving the clamping jaw assembly to a grinding station (located above a grinding processing area) corresponding to the grinding assembly.

S7, starting the longitudinal moving assembly, and after the clamping jaw assembly moves downwards to a position corresponding to the clamping assembly, returning upwards to a waiting state. At this time, the silicon rod can be ground at the current grinding station.

And S8, after the grinding operation is finished, starting the longitudinal moving assembly, and enabling the clamping jaw assembly to move downwards to the position of the grinding assembly and clamp the silicon rod. Thereafter, the jaw assembly is moved upwardly to a blankable state without interference from the grinding assembly.

S9, starting the transverse moving assembly, and enabling the clamping jaw assembly to transversely move to a blanking position corresponding to the blanking assembly.

S10, the fixed clamping jaw assembly and the adjusting clamping jaw assembly of the clamping jaw assembly loosen the silicon rod, so that the silicon rod is transferred to a blanking station of the blanking assembly.

In one possible embodiment, in the grinding machine production line of the present utility model, the feeding assembly and the discharging assembly are located on the same side (left side in the drawing) of the gantry assembly. Thus, the integration level of the grinder production line is improved. In addition, under the condition that the cantilever crane assembly is configured for the grinding machine production line, auxiliary operation aiming at the feeding link and the discharging link can be realized by only configuring one set of cantilever crane assembly, the cost is saved on the premise of ensuring complete functions, and the occupied space corresponding to the cantilever crane assembly is also reduced.

To this end, a single, transport-containing grinding operation in the grinding machine line is completed with respect to the individual silicon rods.

Based on similar logic, a plurality of grinding stations of the grinding machine production line can be in a working state, for example, after the transfer mechanism finishes the feeding operation of the first grinding station, the transfer mechanism can finish the discharging operation of the second grinding station, the feeding operation of the third grinding station, the waiting state and the like.

Clamping assembly and grinding operation mode of reciprocating motion of clamping assembly and grinding assembly

The prior grinding machine mainly comprises a horizontal grinding machine and a vertical grinding machine, wherein the horizontal grinding machine mainly comprises a movable sliding table capable of moving along the length direction of a silicon rod, a clamping assembly arranged on the movable sliding table and capable of clamping the silicon rod, and a grinding assembly capable of grinding the silicon rod. Based on the structure, the prior grinding machine has the working flow that the clamping assembly clamps the silicon rod (the clamping assembly usually comprises a movable chuck and a fixed chuck, the movable chuck moves relative to the fixed chuck to clamp the silicon rod), and the clamping assembly clamping the silicon rod is driven to slide on the movable sliding table, so that the grinding assembly with relatively fixed position along the length direction of the silicon rod can grind the side surface and the chamfer of the whole length range of the silicon rod along with the sliding of the clamping assembly, thereby completing the grinding operation of the silicon rod. Taking a workpiece to be machined as a silicon rod as an example, the process of grinding the silicon rod is generally that firstly, the cut silicon rod (the rough rod) is fixed to a feeding device, after the gesture of the silicon rod is initially adjusted, the silicon rod is conveyed between two chucks of a feeding sliding table device, and the silicon rod is conveyed to a position corresponding to a grinding assembly through the movement of the feeding sliding table device along the axial direction (feeding direction) of the silicon rod. On the basis of this, by bringing the grinding assembly close to the silicon rod and reciprocating the silicon rod in the feed direction, a corresponding grinding operation can be performed on one set of the faces to be ground or on one pair of edges of the silicon rod. Thereafter, by rotating the silicon rod to a second set of faces to be sharpened or another pair of edges, and so on, the blank rod may be machined into a finished rod by a grinding machine as previously described.

It can be seen that the current horizontal grinding machines perform their grinding operations mainly with a reciprocating motion in the feed direction that depends on the silicon rod. Because the reciprocating motion of the silicon rod needs a larger moving stroke, the linear operation corresponding to the larger moving stroke has a certain influence on the precision of the silicon rod after grinding (such as the influence of the straightness of the linear guide rail matched with the linear motion direction on the precision of the silicon rod is larger, etc.), and the influence can bring larger grinding allowance, and the grinding precision of the silicon rod does not reach the standard. Accordingly, the inventors have made intensive analyses and studies and have proposed a grinding machine as a single grinding machine for a grinding machine production line, in which a grinding machine is operated in such a manner that a grinding unit for grinding a silicon rod while the silicon rod is stationary reciprocates in the axial direction of the silicon rod during grinding of the silicon rod by the single grinding machine.

Unlike prior art grinding machines, the grinding machine of the present utility model employs a clamping assembly 18 (typically comprising a fixed chuck and a movable chuck, or both of which are movable chucks) that moves the grinding assembly 1 along the length of the silicon rod 8 in a relatively fixed position after clamping the silicon rod. In particular, the movement of the grinding assembly during the grinding operation of the silicon rod includes a rotational movement as well as a linear movement along the length of the silicon rod. The grinding assembly generally comprises a rough grinding wheel and a fine grinding wheel, and the rotating motion mainly grinds the surface of the silicon rod through the rotation of the rough grinding wheel and the fine grinding wheel under the condition that certain cutting depth and cutting force are ensured along the radial direction of the silicon rod. The chamfering between the side surface of the silicon rod and the adjacent side surface can be ground along with the linear motion of the grinding component along the length direction of the silicon rod. The grinding assembly is linearly moved along the length direction of the silicon rod in an exemplary manner, wherein the grinding machine comprises a sliding table mechanism, and the grinding assemblies arranged in pairs are slidably arranged on the sliding table mechanism, so that the grinding assemblies can move along the length direction of the silicon rod under the action of corresponding driving transmission components.

In one possible embodiment, the grinding assembly 1 mainly comprises a finishing wheel 11 for finishing a silicon rod and a rough grinding wheel 12 for rough grinding a silicon rod. In the utility model, the rough grinding wheel and the fine grinding wheel are positioned at the same station in a concentric manner, and the rough grinding wheel is freely accommodated in a reserved space formed inside the fine grinding wheel. Therefore, the grinding assembly can realize the rough grinding and fine grinding operation of the silicon rod at the same station.

In one possible embodiment, the grinding assembly further comprises a composite shaft comprising a bearing housing 13, in which a first drive shaft (shaft sleeve) 14 comprising a cylindrical structure and a second drive shaft 15 (inner shaft) accommodated in the cylindrical structure are connected to the fine grinding wheel for driving the fine grinding wheel in case of rotation of the shaft sleeve, and the second drive shaft is connected to the coarse grinding wheel for driving the coarse grinding wheel in case of rotation of the second drive shaft. The first transmission shaft and the second transmission shaft are connected through the guide flat key, so that the driving parts such as a motor and the like can drive the first transmission shaft and the second transmission shaft to synchronously rotate. The motor 16 is illustratively connected to the rear end of the compound shaft by a pulley mechanism 17 and thus drives the first and second drive shafts in synchronous rotation.

In a possible embodiment, the grinding assembly 1 further comprises a clamping assembly 18 located at the grinding station, the movable clamping head of which can move relative to the fixed clamping head, so that after clamping the silicon rod to be ground clamped by the clamping assembly, the grinding operation is performed on the silicon rod by the cooperation of the rough grinding wheel and the finish grinding wheel.

Based on the above, the switching between the rough grinding operation and the fine grinding operation can be realized by mainly providing a mechanism for realizing the expansion and contraction of the second transmission shaft corresponding to the rough grinding wheel. Specifically, the silicon rod is extended relative to the finish grinding wheel in the case where the rough grinding operation is required, and is retracted (space reserved) relative to the finish grinding wheel in the case where the finish grinding operation is required. One way of achieving the switching between the rough grinding operation and the finish grinding operation of the rough grinding wheel is to provide the telescopic mechanism with a spring, and the second transmission shaft is in a retracted state relative to the finish grinding wheel under the action of the pre-tightening force of the spring. In this way, when the fine grinding operation is required for the silicon rod, the state of no external force is maintained. In the case of the need for rough grinding of the silicon rod, the rough grinding wheel associated with the spring is extended out of the fine grinding wheel by applying an external force to the spring. If external force can be applied to the gland which is propped against the rear end of the bearing box through external force mechanisms such as a power cylinder, a linear module or a driving transmission mechanism which can realize telescopic movement, the spring is deformed under the action of the external force, and therefore the rough grinding wheel stretches out.

Compared with the mode that stations of the rough grinding wheel and the fine grinding wheel are arranged separately, the grinding assembly integrates and integrates the rough grinding wheel and the fine grinding wheel on the same station by means of the bearing box, namely, each grinding station of a grinding machine production line can realize rough grinding operation and fine grinding operation on a silicon rod at the same time only by reserving the same station area, the structure is more compact, and the installation space of the grinding assembly is greatly reduced. Corresponding to the concentrated arrangement of the rough grinding wheel and the fine grinding wheel in the same station area, each grinding station reduces the supporting mechanism of one set of grinding assembly, thereby saving the number of parts and reducing the equipment cost of the grinding machine production line.
