Referring to fig. 1, the application provides a pole piece production device, which comprises an unreeling assembly 10, a production assembly 20 and a pole ear rubberizing assembly 30. The unwind assembly 10 is used to unwind the output pole piece strip a downstream. The slide assembly 20 includes a cutting mechanism 21 and a conveying mechanism 22. The cutting mechanism 21 is arranged downstream of the unreeling assembly 10 for cutting the passing strip of pole pieces a into pole piece pieces C. The conveying mechanism 22 is disposed on the downstream side of the cutting mechanism 21 for receiving the pole piece sheet C cut by the cutting mechanism 21 and conveying the received pole piece sheet C downstream. The tab taping assembly 30 is disposed on the feed path of the conveyor mechanism 22 such that the conveyor mechanism 22 is capable of conveying the pole piece sheet C thereon past the tab taping assembly 30. The tab taping assembly 30 is used to attach tape to the tab of the routed pole piece web C. The pole piece material C may be a positive pole piece of a solid-state battery, and the tab on the pole piece material C is a positive tab. Of course, in other embodiments, the tab piece C may also be a negative electrode piece of a solid-state battery, and the tab on the tab piece C is a negative electrode tab.
In the pole piece flaking device, in the actual use process, the unreeling assembly 10 unreels and outputs the pole piece material belt A to the cutting mechanism 21 of the flaking assembly 20, so that the pole piece material belt A passes through the cutting mechanism 21 and reaches the upstream end of the conveying mechanism 22. The cutting mechanism 21 cuts the routed pole piece strip a to form a pole piece sheet C, which is at least partially positioned on the conveyor mechanism 22. The transport mechanism 22 transports the pole piece web C downstream to the tab taping assembly 30, which tab taping assembly 30 pastes tape onto the tab of the pole piece web C.
So, paste the sticky tape on the utmost point ear of pole piece sheet material C of pole piece sheet device production, consequently when later stacking this pole piece sheet material C to form solid-state battery's electric core, the utmost point ear on this pole piece sheet material C can be through the sticky tape insulating rather than the pole piece sheet material C of adjacent opposite polarity, avoids appearing the short circuit phenomenon, is favorable to improving solid-state battery's security.
In an embodiment of the present application, the slide assembly 20 further includes a first visual inspection mechanism 26. The first visual inspection mechanism 26 is disposed on the feed path of the conveyor mechanism 22 and is upstream of the tab taping assembly 30. In this way, the first visual detection mechanism 26 is utilized to detect the position of the pole piece material C on the conveying mechanism 22, so that the position information of the pole lug on the pole piece material C is obtained, the pole lug rubberizing assembly 30 can adjust the position according to the pole lug position information detected by the first visual detection mechanism 26, so that the pole lug rubberizing assembly 30 can accurately paste the adhesive tape on the pole lug of the pole piece material C when the pole piece material C passes through the pole lug rubberizing assembly 30, and the position accuracy of rubberizing is greatly improved. Alternatively, the first visual detection mechanism 26 may employ a camera.
In particular to the embodiment, the tab-taping assembly 30 includes a motion driving mechanism 31 and a taping mechanism 32 mounted on a driving end of the motion driving mechanism 31. The motion driving mechanism 31 is communicatively connected to the first visual inspection mechanism 26. The motion driving mechanism 31 can drive the rubberizing mechanism 32 to adjust the position according to the tab position information detected by the first visual detection mechanism 26, so that when the pole piece sheet material C passes through the rubberizing mechanism 32, the rubberizing mechanism 32 can accurately paste the adhesive tape on the tab of the pole piece sheet material C.
Further, the motion driving mechanism 31 can drive the rubberizing mechanism 32 to move along a first direction, a second direction and a third direction, and the first direction, the second direction and the third direction are perpendicular to each other. In this way, the movement driving mechanism 31 drives the rubberizing mechanism 32 to move along the first direction, the second direction and the third direction, so that the rubberizing mechanism 32 can perform position adjustment and rubberizing action.
In the embodiment shown in fig. 1, the first direction is a left-right direction, the second direction is a direction perpendicular to the paper surface, and the third direction is an up-down direction. In the actual use process, the conveying mechanism 22 conveys the pole piece sheet material C to the first visual detection mechanism 26, the first visual detection mechanism 26 detects the position of the pole piece sheet material C, so that the position information of the pole lug of the pole piece sheet material C is obtained, then the motion driving mechanism 31 drives the rubberizing mechanism 32 to move along the first direction and the second direction according to the position information of the pole lug detected by the first visual detection mechanism 26, so that the position of the rubberizing mechanism 32 is adjusted, then the conveying mechanism 22 conveys the pole piece sheet material C to the rubberizing mechanism 32, at the moment, the adhesive tape on the rubberizing mechanism 32 is aligned with the pole lug of the pole piece sheet material C in the third direction, and then the motion driving mechanism 31 drives the rubberizing mechanism 32 to move along the third direction and paste the adhesive tape on the pole lug of the pole piece sheet material C.
It should be noted that the number of tab adhesive assemblies 30 is not limited to one. In other embodiments, the number of tab adhesive assemblies 30 may be plural (i.e., two or more), and the motion driving mechanism 31 of each tab adhesive assembly 30 is communicatively connected to the first visual detection mechanism 26. Thus, each tab rubberizing assembly 30 can independently carry out position adjustment and rubberizing, and is beneficial to improving production efficiency.
In the embodiment, each tab adhesive assembly 30 is sequentially disposed along the feeding path of the conveying mechanism 22, where any two adjacent tab adhesive assemblies 30 are a first tab adhesive assembly and a second tab adhesive assembly located downstream of the first tab adhesive assembly. The first visual inspection mechanism 26 is used for performing position detection on the pole piece sheet material C on the conveying mechanism 22.
The motion driving mechanism 31 of the first tab rubberizing assembly is used for driving the rubberizing mechanism 32 to perform position adjustment according to the detection result of the first visual detection mechanism 26 on the nth pole piece sheet material C. When the nth sheet material C is conveyed to the first tab rubberizing assembly, the tab of the nth sheet material C is located below the rubberizing mechanism of the first tab rubberizing assembly, and at this time, the motion driving mechanism 31 of the first tab rubberizing assembly drives the rubberizing mechanism 32 to rubberize the tab of the nth sheet material C, and then drives the rubberizing mechanism 32 to reset.
The motion driving mechanism 31 of the second tab rubberizing assembly is used for driving the rubberizing mechanism 32 to carry out position adjustment according to the detection result of the first visual detection mechanism 26 on the (N+1) th pole piece sheet material C, when the (N+1) th pole piece sheet material C is conveyed to the second tab rubberizing assembly, the pole tab of the (N+1) th pole piece sheet material C is positioned below the rubberizing mechanism of the second tab rubberizing assembly, and at the moment, the motion driving mechanism 31 of the second tab rubberizing assembly drives the rubberizing mechanism 32 to rubberize the pole tab of the (N+1) th pole piece sheet material C and drives the rubberizing mechanism 32 to reset. Therefore, the adjacent two tab rubberizing assemblies 30 can independently carry out position adjustment and rubberizing, and the adjacent two tab rubberizing assemblies 30 sequentially rubberize the tabs on different pole piece sheet materials C, so that mutual interference caused by the fact that the two tabs are relatively close to each other is avoided.
It should be noted that, the rubberizing mechanism 32 includes an adsorption plate, and the adsorption plate can absorb the adhesive tape in a vacuum adsorption manner, and then the absorbed adhesive tape is stuck to the tab of the pole piece sheet material C under the driving action of the motion driving mechanism 31. Of course, other mechanisms may be used for the rubberizing mechanism 32, as long as the rubberizing mechanism can adhere the adhesive tape to the tab of the pole piece sheet material C, and the rubberizing mechanism is not limited herein.
In an embodiment of the present application, the slide assembly 20 further includes a primary drive traction mechanism 23. The main drive traction mechanism 23 is arranged between the downstream of the unreeling assembly 10 and the upstream of the severing mechanism 21 and is arranged close to the severing mechanism 21. The main drive traction mechanism 23 is used for traction of the passing pole piece material belt A to convey to the cutting mechanism 21. In this way, the main driving traction mechanism 23 moves a certain length to the downstream cutting mechanism 21 each time to draw the pole piece material belt a, so that the accurate cutting position of the cutting mechanism 21 each time is ensured, and the length and the size of the pole piece material C formed by cutting the pole piece material belt a are consistent.
In the embodiment, the conveying mechanism 22 is a vacuum belt conveyor, and can convey the pole piece sheet material C downstream and simultaneously fix the pole piece sheet material C by utilizing vacuum adsorption, so that the pole piece sheet material C is prevented from being shifted or even falling relative to a conveying belt in the downstream conveying process. In this way, in actual use, the main drive traction mechanism 23 is used to draw the pole piece material belt a to move a certain distance to the cutting mechanism 21, so that the starting end of the pole piece material belt a reaches the conveying belt of the conveying mechanism 22 and is adsorbed and fixed on the conveying belt, and then the cutting mechanism 21 cuts the pole piece material belt a. At this time, part of the pole piece sheet material C is adsorbed and fixed on the conveying belt of the conveying mechanism 22, and then the conveying belt of the conveying mechanism 22 moves downstream, thereby driving the pole piece sheet material C to move downstream together.
In an embodiment of the present application, the slide assembly 20 further includes a second visual inspection mechanism 27. The second visual detection mechanism 27 is arranged on the conveying path of the conveying mechanism 22 and is located at the upstream of the tab rubberizing assembly 30, so that the pole piece sheet C on the conveying mechanism 22 can pass through the second visual detection mechanism 27 and then pass through the tab rubberizing assembly 30 in the conveying process. Thus, in actual use, the conveying mechanism 22 conveys the pole piece sheet material C sequentially through the second visual inspection mechanism 27 and the tab taping assembly 30. When the conveying mechanism 22 conveys the pole piece sheet material C to the second visual inspection mechanism 27, the second visual inspection mechanism 27 performs surface defect inspection on the pole piece sheet material C. When the conveying mechanism 22 conveys the pole piece sheet material C to the pole tab rubberizing assembly 30, the pole tab rubberizing assembly 30 pastes the adhesive tape onto the pole tab of the pole piece sheet material C. Alternatively, the second visual detection means 27 may each employ a camera.
It should be noted that, the pole piece pieces C having the surface defect detected by the second visual detection mechanism 27 may be removed in the subsequent process, so as to ensure that the pole piece pieces C flowing into the stacking station are pole piece pieces C having acceptable size and surface quality, thereby greatly improving the quality of the solid-state battery.
In particular embodiments, the slide assembly 20 further includes a dust removal mechanism 25, the dust removal mechanism 25 being disposed in the feed path of the conveyor 22, and the dust removal mechanism 25 being located upstream of the tab taping assembly 30. In this way, in actual use, the conveying mechanism 22 is capable of conveying the pole piece sheet material C through the dust removing mechanism 25. When the conveying mechanism 22 conveys the pole piece material C to pass through the dust removing mechanism 25, the dust removing mechanism 25 removes dust on the pole piece material C, so that the surface cleanliness of the pole piece material C is ensured to meet the process requirements.
In particular embodiments, the slide assembly 20 further includes a static and de-ironing pin mechanism 24. The de-static and de-ironing pin mechanism 24 is disposed on the feed path of the feed mechanism 22, and the de-static and de-ironing pin mechanism 24 is located upstream of the tab-taping assembly 30. In this manner, in actual use, the transport mechanism 22 is capable of transporting the pole piece web C through the de-static and de-pinning mechanism 24. When the conveying mechanism 22 conveys the pole piece sheet material C through the static electricity removing and de-pinning mechanism 24, the static electricity removing and de-pinning mechanism 24 performs static electricity removing and de-pinning treatment on the pole piece sheet material C.
Optionally, on the feeding path of the feeding mechanism 22, a static and de-ironing pin removing mechanism 24, a dust removing mechanism 25, a first visual detecting mechanism 26, a second visual detecting mechanism 27 and a tab taping assembly 30 are arranged in this order. That is, the conveying mechanism 22 is capable of conveying the pole piece sheet material C sequentially through the static and de-ironing pin removing mechanism 24, the dust removing mechanism 25, the first visual inspection mechanism 26, the second visual inspection mechanism 27 and the tab rubberizing assembly 30.
In the embodiment of the application, the pole piece preparation device further comprises a cutting assembly 40 and a positioning assembly 50. The cutting assembly 40 and the positioning assembly 50 are both disposed between the downstream of the unwind assembly 10 and the upstream of the primary drive traction mechanism 23 of the pellet assembly 20, with the cutting assembly 40 being located upstream of the positioning assembly 50. The pole piece material belt A unreeled and output by the unreeling assembly 10 sequentially passes through the cutting assembly 40, the positioning assembly 50, the main driving traction mechanism 23 and the cutting mechanism 21. In this way, the cutting assembly 40 is configured to cut the passing pole piece material belt a, so that a positioning notch is formed on the pole piece material belt a. The positioning assembly 50 is used for positioning the pole piece material belt a by utilizing the positioning notch on the pole piece material belt a, so as to ensure that the length dimension of the pole piece material C formed by cutting the pole piece material belt a by the cutting mechanism 21 meets the precision requirement. It should be noted that the positioning notch may be a V-shaped notch, or may be a notch of another shape, which is not limited herein, as long as the positioning assembly 50 is convenient to position the pole piece material belt a.
Optionally, the positioning assembly 50 includes a camera with which the position of the positioning notch on the pole piece web a is detected. When the camera detects that the positioning notch on the pole piece material belt A moves to the preset position, the main drive traction mechanism 23 stops traction of the pole piece material belt A to move downstream, namely, the pole piece material belt A is positioned.
It should be noted that, in some embodiments, the tab is provided on the pole piece material strip a unreeled and output by the unreeling assembly 10, so that the tab die-cutting assembly is not required. In other embodiments, the unreeling assembly 10 unreels the output pole piece material strip A without tabs, and therefore a tab die cutting assembly is required. Specifically, the tab die cutting assembly is disposed between the downstream of the unwind assembly 10 and the upstream of the cutoff assembly 40 for die cutting the routed pole piece web a to form the tab on the pole piece web a. Of course, the tab die cutting assembly may also be disposed between the downstream of the cutting assembly 40 and the upstream of the positioning assembly 50, without limitation.
In an embodiment of the application, the unreeling assembly 10 comprises two unreeling mechanisms 11 and a tape receiving mechanism 12 arranged downstream of the two unreeling mechanisms 11. Each unreeling mechanism 11 can load the pole piece material roll and drive the pole piece material roll to rotate so as to unreel and output the pole piece material belt A to the downstream. In actual use, one of the unwinding mechanisms 11 drives the pole piece material roll thereon to unwind downstream to output the pole piece material strip A, and meanwhile, the other unwinding mechanism 11 loads the pole piece material roll and waits for unwinding. When the unwinding of the pole piece material roll on the unwinding mechanism 11 being unwound is completed, the tape receiving mechanism 12 cuts off the pole piece material tape a passing through, and connects the downstream cut end of the pole piece material tape a with the material tape start end of the pole piece material roll on the unwinding mechanism 11 waiting to be unwound (for example, the connection is achieved by using adhesive tape). At this time, after the one unreeling mechanism 11 which is unreeling changes the pole piece material roll, the state is switched to a state waiting for unreeling, the unreeling mechanism 11 which is waiting for unreeling is switched to a state of unreeling, and the pole piece material belt A is continuously conveyed to the downstream.
After the pole piece material strip a is cut, two cut ends are formed at the fracture, wherein the upstream cut end is located at the upstream and the downstream cut end is located at the downstream. The tape splicing mechanism 12 is used for splicing the downstream cut end of the pole piece material tape A and the starting end of the material tape on the pole piece material roll on the unreeling mechanism 11 waiting for unreeling.
In particular to the embodiment, the unwind assembly 10 further comprises a tension adjustment mechanism disposed between the downstream of the taping mechanism 12 and the upstream of the cutting assembly 40 for tensioning and adjusting the tension of the pole piece web a.
Further, the tension adjusting mechanism includes a first fixed roller 131, a movable roller 133, a second fixed roller 135, and a movement driving member 137. The first fixed passing roller 131 is disposed upstream of the movable passing roller 133, and the second fixed passing roller 135 is disposed downstream of the movable passing roller 133. The first fixed passing roller 131, the movable passing roller 133 and the second fixed passing roller 135 supply the pole piece material tape a to be wound around in sequence. The motion driving piece 137 is in driving connection with the movable roller 133, and is used for driving the movable roller 133 to move relative to the first fixed roller 131 and the second fixed roller 135, so as to drive the pole piece material belt A to be tensioned or loosened, and the purpose of adjusting the tension of the pole piece material belt A is achieved. The moving driving member 137 may be configured to drive the movable roller 133 to move along a straight line, or may be configured to drive the movable roller 133 to swing, so long as the tension of the pole piece material belt a can be adjusted by changing the position of the movable roller 133, which is not limited herein.
In particular to the embodiment, the unwind assembly 10 further comprises a de-skew mechanism 14, the de-skew mechanism 14 being arranged between downstream of the tension adjustment mechanism and upstream of the cutting assembly 40. The deviation correcting mechanism 14 is used for driving the pole piece material belt A to carry out position adjustment along the width direction, so that the position accuracy of the pole piece material belt A passing through the cutting assembly 40, the positioning assembly 50 and the sheet making assembly 20 along the width direction meets the process requirements.
In particular embodiments, the unwind assembly 10 further includes a web buffering mechanism 15, the web buffering mechanism 15 being disposed between the downstream of the de-skew mechanism 14 and the upstream of the cutting assembly 40. The material belt buffering mechanism 15 is used for buffering the material belt A of the pole piece, that is, the material belt A of the pole piece, which is unreeled and output by the unreeling mechanism 11, is buffered in the material belt buffering mechanism 15, and the main driving traction mechanism 23 is used for traction of the material belt A of the pole piece buffered by the material belt buffering mechanism 15. It should be noted that, the material tape buffer mechanism 15 may adopt a relatively mature prior art, so long as it can buffer the pole piece material tape a, and is not limited herein.
Based on the pole piece manufacturing device, the application further provides solid-state battery manufacturing equipment. The solid-state battery manufacturing apparatus comprises a lamination device and a pole piece production device as described in any of the above embodiments. The pole piece flaking device is used for preparing pole piece flakes C by utilizing the pole piece material belt A. Lamination means are used to stack the pole piece webs C to form a solid state battery.
When the electrode sheet material C is a positive electrode sheet, the lamination device is used to stack the electrode sheet material C and a negative electrode sheet to form a solid-state battery. When the pole piece material C is a negative pole piece, the lamination device is used for stacking the pole piece material C and the positive pole piece to form the solid-state battery.
