Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an air-core coil winding insertion device for winding an air-core coil (high-frequency coil) used in an electric circuit of an electronic tuner and inserting it into a board. Regarding. [Prior art] A conventional air-core coil insertion device is disclosed in Japanese Patent Application Laid-Open No. 17800/1986.
As described in Japanese Patent No. 0, a coil that has been pre-wound into a predetermined shape is positioned in a coil supply section, and from this state, the leads of the coil are chucked from the left and right sides and inserted into the substrate. Additionally, coil winding devices generally wind coils around a winding shaft and then drop the coils in bulk onto a chute installed at the bottom of the winding shaft, and these coils are positioned and chucked by a coil supply section by some means. It is inserted into the board. [Problems to be Solved by the Invention] In the above conventional technology, the winding process and insertion process of the air-core coil are separated, so the wound coil is in a free state, so the loose coils are separated and aligned. There was a reliability problem in separating and arranging the coils because a device was required and flexible coils in particular tend to get tangled, and there was no consideration given to high-density insertion of coils and insertion of multiple types of coils. There were problems such as the chuck interfering with adjacent parts and making it impossible to insert the coil, or the inability to insert a coil with a different lead pitch. An object of the present invention is to provide an air-core coil winding insertion device that can improve the reliability of positioning of wound coils, and can insert coils at high density and insert many types of coils. [Means for Solving the Problems] In order to achieve the above object, the air-core coil winding insertion device according to the present invention separates coils wound with a rough winding pitch and flexible coils with a small wire diameter from a loose state. Considering that aligning the coil leads is very difficult in terms of reliability, the coil leads are clamped and positioned when the wound coil is on the winding shaft, and then the coil leads are removed from the winding shaft. The structure is such that the two coil leads are re-chucked and inserted into the board in this state, and the coil wound around the winding shaft is continuously positioned and inserted into the board without being separated. This is what I did. Furthermore, for insertion into the board, the coil lead is gripped by a pair of chuck claws that slide diagonally from above, making it possible to insert the coil onto the board at high density. Furthermore, the pair of chuck claws are made into a unit so that the unit for each coil lead can be moved in the lead pitch direction, and the winding of the coil is configured to have multiple types of winding shafts installed on an index table for switching. , which allows winding and insertion of various types of coils. [Function] The air-core coil winding insertion device described above positions the wound coil on the winding shaft without breaking it apart, and then inserts the coil lead with the coil removed from the winding shaft. Since the coils are inserted into the board after they are assembled, there is no need to separate and align the coils in bulk, which simplifies the mechanism and eliminates the causes of entanglement between coils and bending of the leads. The reliability of positioning and insertion work is greatly improved. Furthermore, since the coil lead is chucked obliquely from above when inserting the coil, there is no interference between the already inserted coil on the board and the chuck claw, allowing high-density insertion of the coil. Furthermore, by making the pitch of the two sets of chuck claws variable and changing the diameter of each of the four winding shafts, for example, it is possible to deal with a wide variety of coils, and it is possible to wind and insert coils with different winding diameters and numbers of turns. .

The outline of this device will be explained with reference to FIGS. 1 and 2.

In the winding jig section A of FIG. 1, four winding jigs are arranged at 900-degree intervals on an index plate fixed to the output shaft of an intermittent drive device 4 fixed on a base 3. The winding lead forming section B winds the coil 1 shown in FIG. 2 to form the cocoil leads la and lb into a predetermined shape. The lead positioning section C positions and clamps the leads la and lb of the coil 1 on the winding shaft and transfers them to the coil lead clamp jig section. The XY positioning unit D consists of a linear slide, a ball screw, a DC motor, etc. for moving the insertion head E in the XY coordinate directions. The insertion head E grasps the leads la and lb of the coil 1 and inserts them into predetermined substrate holes 2a and 2b. The wire rod delivery section F sends out the wire wound on a reel by a motor. The transport compare section G transports the substrate 2. The coil lead clamp jig part H is the coil lead la.

In the lead positioning section C, after positioning the leads la and 1b of the coil L at a predetermined pitch, the coil 1 is removed from the winding shaft and transferred to the coil lead clamp jig section H. Next, the position where the index plate is rotated 90 degrees is an empty station, and the next 90 degrees rotation brings the coil 1 to the coil delivery position to the insertion head E of the XY positioning unit D.
Here, the insertion head E, which has been moved to just above the coil lead clamp jig part H by the XY positioning unit D, descends, grips the two coil leads la and lb with a pair of chuck claws, and then ascends. After moving to a predetermined position on the board 2, it descends again and inserts the coil leads la and lb into the predetermined holes 2a and 2b of the board 2. After inserting a predetermined amount of coils 1 into the board 2 by repeating the above general procedure,

The process of winding the coil 1 and shaping the coil leads la and lb into a predetermined shape will be explained. First, the winding lead forming mechanism of the winding lead shaped portion B shown in FIG. 6 will be explained. An L plate 31 is fixed on a slide 52 which is fixed on the base 3 in FIG. 6 and is slidably movable. The lower part of the L plate 31 engages with a ball screw 51, and the other end of the ball screw 51 is connected to the rotating shaft of a pulse motor 35 fixed on the base 3. Therefore, pulse motor 3
5, the ball screw 51 rotates and the L plate 3
1 moves in the direction of arrow X-x'. A vertically slidable slider 54 is fixed to the upper part of the L plate 31, and an upper forming arrow 36 is further fixed to the slider 54. The tip of the rod 37a of the cylinder 37 fixed to the upper part of the L plate 31 is fixed to the upper forming arrow 36, and an upper forceter 38 is fixed to the side surface of the upper forming arrow 30. Similarly, L plate 31
A lower or shaped arrow 32 is fixed to the middle part of the gusset via a slider (not shown) so as to be able to slide vertically, and the tip of a rod 33a of a cylinder 33 fixed to the L plate 31 is fixed to the lower end of the lower end. A lower forceter 34 is fixed to the side surface of the arrow 32. Next, the wire rod feeding mechanism of the winding jig or shaping section A of FIG. 6, in which the wire rod is fed from the wire feeding section F, will be explained. A bracket 43 is fixed to a plate 48 which is fixed to a slider 52 which is fixed to the base 3 shown in FIG. A ball screw 49 is rotatably engaged. The rond of the cylinder 47 fixed to the bracket 43 is swingably connected to a lock claw 44, and the lock claw 44 swings about a pin 45 fixed on the bracket 43 as a fulcrum. The L plate 46 is fixed to the bracket 43, and when the lock claw 44 is rotated by the cylinder 47 about the pin 45, the wire 100 is sandwiched between the L plate 46 and the tip of the lock claw 44 and is clamped. By rotating the pulse motor 50 by a predetermined amount in this state, the bracket 43 is sent in the direction of arrow Y-Y' by the rotation of the ball screw 49, and the wire rod 100 is placed at a predetermined position on the winding shaft 22 of the winding jig section A. send to. The nozzle 39 at the fixed position of the winding lead or shaping mechanism normally passes the wire 100, but when winding, the arrow 2
-Move in two directions to regulate line position. On the other hand, a plate 40 is fixed to the side surface of the block 7 of the winding jig in part A of the winding jig shown in FIG. 6, and a lever 42 is rotatably supported on the plate 40 with a pin 41 as a fulcrum. One end of the lever 42 normally maintains a slight gap with the coil presser 21. Next, the operation of the winding lead portion B will be explained with reference to FIGS. 7 to 1l. Figures 7 to 11 are explanatory diagrams of the coil winding and lead forming operations of the winding lead shaped portion B. First, as shown in Fig. 7, the winding lead forming part B of Fig. 6 is
The wire rod 100, which is clamped by the lock claw 44 and the L plate 46 with the pin 45 of the wire feed mechanism as a fulcrum, is passed through the nozzle 39 of the winding lead or shaping mechanism in the Y direction to the winding shaft 22 of the winding jig section A. It is sent to a predetermined position at the top by rotation of the pulse motor 50. Next, as shown in FIG. 8, the upper or lower arrow 36 and lower arrow 32 of the winding lead forming mechanism are connected to the cylinder 37 of FIG. 33, they move in a direction toward each other around the winding shaft 22. Here, an N-shaped groove that escapes the winding shaft 22 is formed in the upper orifice 36 that holds the tip of the wire 100, and a U-shaped groove that escapes the winding shaft 22 is formed in the lower orifice 32. Therefore, the winding start lead 1a is formed by folding the tip end of the wire 100 from the outer periphery of the winding shaft 22 at right angles to the axial direction on the inner surface of the U-shaped groove. At this time, the coil presser 2l of the winding jig part A deflects the compression spring 19 by the action of the lever 42 shown in FIG. Maintains a gap. Further, the upper cutter 38 side of the upper cutter 36 is shaped so that the wire 100 escapes in the direction of the arrow zz' as shown in FIG. After the wire rod 100 shown in FIG. 8 is bent at right angles, the lever 42 shown in FIG. Next, as shown in FIG. 9, the upper forming arrow 36 and the lower forming arrow 32
are returned to their original positions, and at the same time, the lock pawl 44 is swung by the cylinder 47 in the direction of releasing the wire 100, and then returned to its original position in the Y' direction by the pulse motor 50.
In this state, the winding shaft 22 rotates by a predetermined amount to form the coil 1. The rotation of the winding shaft 22 is carried out as described above by the pulse motor 64 and the flange 67 of the winding shaft rotation drive section (2) in FIG. Here, the winding shaft 22 stops at a position where the winding shaft 22 has been wound by a predetermined number of windings plus an angle θ.

Then, as shown in FIG. 10, while the winding shaft 22 is rotating, the L plate 31 is moved by a distance Q in the direction of the arrow X by the pulse motor 35 of the winding lead shaping mechanism shown in FIG.

Therefore, both the upper forming arrow 36 and the lower forming arrow 32 move to a position where the inner surface of the gate-shaped groove having the dimension L, which is opposite to the surface on which the winding start lead 1a is formed, comes into contact with the outer diameter of the coil 1. In this state, operate the upper forming arrow 36 and the lower forming arrow 32 again,
The winding end lead 1b is shaped by bending the end of the coil 1 from the outer circumference of the winding shaft 22 at right angles to the axial direction on the inner surface of the groove. At the same time, the wire 100 is sandwiched between the upper forceter 38 and the lower forceter 34 and cut. Next, as shown in FIG. 11, when the upper or lower arrow 36 and lower arrow 32 return to their original positions, the winding end lead 1b returns by an angle θ due to springback and matches the directional position of the winding start lead 1a. do. In other words, the angle θ is the springback amount, which changes depending on the number of turns of the coil 1 and the wire diameter. Therefore, if this amount of springback is known in advance, replacing it with the amount of rotation of the pulse motor 64 of the winding shaft rotating member shown in Fig. 4 and inputting it to the control section will eliminate the need for parts replacement or adjustment. This can be handled by software. Further, the pulse motor 35 of the winding lead forming section B shown in FIG.
Moving only the dimension shown in Figure 0 can accommodate many different diameters of the winding shaft 22, and if there are many different diameters of the winding shaft 22,
The rotation amount of the pulse motor 35 can be continuously varied by inputting the data so as to control the rotation amount of the pulse motor 35 depending on the diameter. From FIG. 11 onwards, after the winding shaft 22 is rotated so that the coil leads la and lb face the lower forming arrow 32 side at the bottom, the flange 67 and pin 69 rises and the connection with the flange 14 of the winding jig part A is cut off. At the same time, pin 1 is attached to flange 14.
5 engages to restrict rotation of the winding shaft 22.

Next, the entire insertion head is raised by the cylinder 114 of the insertion head section E, and then moved to a predetermined position on the substrate 2 by the XY positioning unit D. Here, the insertion head of the insertion head portion E is lowered again by the cylinder 114, and as shown in FIGS.
As shown in FIG. 1, in the coil chuck state shown in FIG. 28, the coil leads la and lb are inserted into predetermined holes 2a. Insert it into 2b and stop. Thereafter, the cylinder 155 is operated to retract the chuck jaws 150 as shown in FIGS. 30 and 32. Next, by operating the cylinder 144 (FIG. 19), the busher 139 is lowered, and the side guide 140 is also lowered accordingly. From there, the protrusion l49 (FIG. 19) of the side guide 140 is attached to the chuck holder 1.
It hits the stop surface of 34 and stops at the fixed position. Further, when the pusher 139 is lowered, the coils 1 shown in FIGS. 30 and 32 are inserted to the home position. Also, the direction of insertion into the board 2 (
The switching in the XY directions relative to the plane is performed by rotating the shaft 177 via the rack 120 using the cylinder 122 (FIG. 19). Also, the coil lead la, 1
．． If the pitch between b is different, the pulse motor 128
By operating the cam part 125 and rotating the cam part 125, the interval between the pair of chuck holders 134 is changed. As a result, the distance between the pair of chuck jaws 150, side guide 140, and pusher 139 changes simultaneously. According to this embodiment, since the structure is such that the coil is positioned on the winding shaft and delivered to the insertion head without leaving the wound coil free, the coils can be entangled with each other or the coils can The reliability of coil supply is significantly improved without the occurrence of dirt or bending of the coil lead due to friction.

In addition, there are four winding jigs in the winding jig part and the V in the lead positioning part.
It has a structure in which each positioning part has two grooves and can be switched by a coil, and one insertion head part can also continuously vary the distance between a pair of chuck claws by a pulse motor, so it can be used with at least two types of coils. can be inserted continuously or alternately, and is very effective when inserting several types of coils on one board. Also, regarding coil insertion, it is possible to ensure flexible coil insertion by chucking the lead, guiding the side of the coil, and pushing in with a pusher. [Effects of the Invention] According to the present invention, the reliability can be greatly improved because the wound coil is positioned on the winding shaft without being separated, and is then chucked and inserted into the board. The coil lead is chucked diagonally from above and there is no interference with the already inserted coil, allowing for high-density insertion.Furthermore, the winding shaft diameter is changed and the chuck pitch is varied for insertion, allowing for a wide variety of winding diameters and numbers of turns. It has the effect of being able to wind and insert a coil.
