Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a winding device for winding a wire around the core of a video head, a magnetic head for a computer, or the like.

Conventional configuration and its problems Conventionally, a toroidal winding machine has been used to wind wires in hollow holes. A toroidal winding machine winds wire onto a spool in advance, and the spool and shuttle rotate the hollow hole in the material to be wound.
It winds wires, but since the spool and shuttle need to rotate through a hollow hole in the object to be wound, there is a limit when the hollow hole becomes smaller, and there is a limit of 1 mm in diameter.
It is impossible to wind a wire in a hollow hole as shown below. The winding wire for the video head is extremely thin, with a wire diameter of 0.03 mm to 0.05 mm, and the hole size is small, about 0.25 mm x 0.3 mm.
It was technically difficult to automate the process, and the process relied on manual labor or the use of simple jigs and tools.

On the other hand, various winding methods have recently been proposed for difficult winding, but there are still many problems to be solved. One method is to grasp the wire near the tip with a winding chuck, pass it through the winding hole in the core of the magnetic head, pull out the wire with a pull-out chuck, and then grip the wire with the winding chuck. A winding device has been proposed in which the wire is re-wound around the core and passed through the winding hole of the core again.

However, when winding the wire around the core, the tip of the wire is held by the winding chuck, but the other parts are free. Sometimes I can't wrap it. In other words, the wire is wound between the winding hole in the core and the side edge of the core, but the loop-shaped wire in the middle of winding falls to the front side of the core, causing the wire winding hole in the core to connect with the front edge of the core. It may be wrapped between
In addition, as the winding progresses, the gap in the core winding hole becomes smaller, making it difficult to pass the wire through. Therefore, it is necessary to distribute the winding wire at appropriate positions so that the winding position is not concentrated in one place in the hole. However, it is not possible to regulate the winding position in this way. Furthermore, even if an attempt was made to perform aligned winding, the winding positions could not be sequentially shifted, making it impossible to perform aligned winding.

A method using vacuum suction (Japanese Unexamined Patent Publication No. 148812/1983) has been proposed to regulate the winding position, but the regulating effect is insufficient and the winding position cannot be reliably regulated. Further, since a vacuum suction device is required, there is a problem that the structure becomes complicated and the cost increases.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a winding device that can regulate the winding position and has a simple structure.

Composition of the Invention The winding device of the present invention includes a gripping means for gripping a wire, passing it through a winding hole of a toroidal core, and winding it, and a pulling means for pulling out the passed wire. A guide member that can move forward and backward is provided, and a wire guide slit that is perpendicular to the front-rear direction of the core is formed between the tips of the guide member on the wire insertion side of the winding hole of the core.

The guide member on the front side of the core prevents the loop-shaped wire material in the middle of winding from falling forward. Further, the winding position of the wire rod is regulated by the slit between both guide members. The guide member is moved back and forth in order to avoid interference with the gripping means. The core holding means is movable in the longitudinal direction of the core, and this movement shifts the position of the core with respect to the slit to change the winding position.

A belt conveyor 89 is provided along the front edge of the substrate 6, and can transport and position the jig 88 pitch by pitch. Reference numeral 89 denotes a core transfer device, in which a supply chuck 92 and a take-out chuck 93 are attached side by side to a core transfer portion 91 which is attached to a rotation post 90 and rotates. The supply chuck 92 and the take-out chuck 93 can be raised and lowered by raising and lowering cylinders 94 and 95 provided in the core transfer section 91, respectively.

The operation of the above configuration will be explained. First, an outline of the overall operation will be explained.

The core 1 is supplied to the core holding section 12 and held.

The winding chuck 18 is moved horizontally to the wire supply gripping and cutting device 60, and the winding chuck 18 grips the wire 2 and returns it to its original position (origin position or winding position).

At one winding position I of the core 1 (Fig. 1C),
The wire rod 2 is wound with the required number of turns using the winding chuck 18 and the drawer chuck 30.

The core 1 is inverted by the holding part 12, and the wire rod 2 is wound in the required number of turns at the other winding position.

Take out core 1.

FIG. 22 schematically shows the overall operation. Description of this figure will be omitted.

Next, each operation will be explained in detail.

Core supply and take-out operation From the state in which the core transfer section 91 is rotated to the position shown by the solid line in FIG. 21, the take-out chuck 93 is lowered, grips the core 1 with completed winding, and moves up. Next, the core holder 12 is moved by the distance between the supply chuck 92 and the take-out chuck 93, and the supply chuck 92 is lowered to place the unwound core 1 on the core holder 12. This state is the state of the core holding portion 12 shown by the solid line in FIG. Thereafter, the core holding section 12 moves in the Y-axis direction toward the position where winding is to be performed. At the same time, the core transfer section 91 rotates and returns onto the jig 88 (the state shown by the chain line in FIG. 21). Then, the core 1 with completed winding held by the take-out chuck 93 is placed on the jig 88. The supply chuck 92 then descends and picks up a new unwound core 1. When the gripping is completed, and before the winding of the previously supplied core 1 is completed, the core transfer unit 9
1 rotates to the solid line position in FIG. 21 and waits, and the jig 88 is conveyed one pitch by the conveyor 89.

The core holder 12 carrying the aforementioned core 1 and heading toward the winding position temporarily stops at a position that can be recognized by the TV camera 8 along the way. Here, core 1 with TV camera 8
The center position of the winding hole 3 is read and memorized. When the core maintenance part reaches the winding position, winding is performed. During winding, the core 1 is reversed once as described below, but when the winding is completed, the core 1 is in the same state as the initially supplied core 1, so the core holder 12 is Rotate to flip it again. After this, the XY equipped with the core holding part 12
The moving table 14 moves to the position where the core 1 is taken out by the above-mentioned takeout chuck 93.

Wire supply operation, wire end processing operation, etc.: As shown in FIG. 23, the wire rod 2 from the winding bobbin 53 is initially set in the wire supply gripping and cutting device 60 by hand. This state becomes the state shown in FIG. 24A. Next, as shown in FIG. 23 or FIG. 24B, the wire rod 2 is held by the winding chuck 18 (only the tip cross section of the winding chuck 18 is shown in the figure for simplicity), and the wire rod 2 is wound. The wire 2 is cut by the cutting element 63 of the wire supply cutting and gripping device 60 so that the tip of the wire has a predetermined length l (FIG. 15B) from the wire chuck 18. Thereafter, the horizontal, vertical, and rotational movements of the winding chuck 18 are combined to move the tip of the wire 2 to the position recognized by the TV camera 8, and the position of the tip of the wire 2 is recognized and stored. Comparing this recognized wire rod tip position with the position of the winding hole 3 of the core 1 recognized in the core supply process described above,
A difference is calculated in the positional relationship in which the tip of the wire rod 2 passes through the winding hole 3, and the position of the core 1 is corrected by the XY moving table 14. Note that the position where the tip of the wire 2 is recognized is exactly the same as the position where the winding hole 3 of the core 1 is recognized.
Since the core holder 12 moves further after recognizing the winding hole 3, it does not interfere with the winding chuck 18 when recognizing the tip of the wire 2. This allows the TV camera 8 to be shared. Note that until now, the wire 2 remains connected to the wire supply device 52.

Next, as shown in FIG. 23 or FIG. 24C, the winding chuck 18 is reversed, the tip of the wire 2 is passed through the winding hole 3 of the core 1, the tip is grasped with the drawer chuck 30, and the wire is wound. Pull the wire downward to the required length (preset according to the number of turns). When the wire rod 2 is pulled out to the required length, the wire supply gripping and cutting device 60 grips the wire rod 2. This stops the wire from being drawn out from the wire supply device 52.

Thereafter, as shown in FIG. 23, the wire 2 drawn out is repeatedly wound on one winding position (FIG. 1C) of the winding hole 3 of the core 1 for a set number of turns. The winding operation will be explained in detail later. When the set number of turns of the wire is completed, the tip of the wire is exposed to the wire processing hole 4 of the core 1, and the wire rod 2 is sucked by vacuum suction using the suction pipe 15 integrated with the core holding part 12, and one of the windings is finish. In this state, the other end of the wire 2 is still connected to the winding bobbin 53. When one winding is completed, the wire 2 at the other end is placed in the other winding position of the core 1, as shown in FIGS. 23 and 24D.
In order to wind the wire, the core 1 is inverted at the core holder 12, and the winding chuck 18 goes to the wire supply gripping and cutting device 60 to pick up the other end of the wire 2. At this time, the other end of the wire 2 is cut. Furthermore, at this time,
Since the orientation of the tip of the first line feed 2 is different, the line feed gripping and cutting device 60 is divided into two cutting elements 63 and 6.
4 and gripping elements 61 and 62. Winding chuck 18 holding the other end of wire rod 2
moves toward the recognition position of the tip of the wire 2, but at this time, to prevent the wire 2 from wrapping around the core 1 unnecessarily,
The winding chuck 18 moves under the core 1 in a circular manner. When it reaches the recognition position, the tip of the wire 2 is recognized and the winding operation begins, as shown in FIGS. 23 and 24E. At this time, the difference from the operation on the one end side is that the edge of the wire 2 is cut off from the winding bobbin 53 and that the winding hole is not recognized. Since the initial position of the winding hole is stored, that information is used to correct the difference caused by the reversal. When the set number of turns is completed, the tip of the wire 2 faces the wire processing hole 4 of the core 1 and is sucked in by the suction pipe 15, as described above, and the winding of the other end is completed.

Winding operation: Figure 25 shows the continuous operation of the winding chuck 18. Regarding the main states of the winding chuck 18, A is the recognition position, B is the wire threading preparation position, and C is the wire threading preparation position. The wire threading position and D are defined as the regripping/cutting position. The winding chuck 18 passes through states A, B, C, and D and completes one winding. The operation of the line guide (Figures 19 and 20) will not be discussed here.
Details will be explained later. At recognition position A, winding chuck 1
The end of the wire rod 2 held at 8 is read by the recognition TV camera 8, and the amount of positional deviation is corrected by operating the XY moving table 14 on which the core holding section 12 is mounted. Rotate 180° at step 19 to reach wire threading preparation position B. The rotational movement is driven by a pulse motor 20 for rotating the winding chuck so that it stops at the correct position each time. When rotated 180°, the wire 2 held by the winding chuck 18
The tip faces vertically downward and coincides with the center of the winding hole 3 of the core 1 or the vertical line at the target position where the wire 2 is passed. Next, the winding chuck 18 is lowered by the winding chuck vertical drive unit 22, the tip of the wire 2 is passed through the winding hole 3, and the winding chuck 18 reaches the wire passing position C. At the wire threading position C, as shown in FIG. 26, the tip of the wire 2 passes through the winding hole 3 of the core 1 and protrudes below the core 1 to a length that can be grasped by the drawer chuck 30. At the same time, the winding chuck 18 is opened and the wire 2 is released. Next, the drawer chuck 30 grips the wire 2 and lowers it vertically by a preset amount. The drawer chuck vertical drive unit 31 is driven by a pulse motor 33 in order to freely set the amount of movement and to move accurately. When the drawer chuck vertical drive unit 31 is lowered, the wire rod 2 held by the drawer chuck 30 has almost no slack in the vertical direction with respect to the winding hole 3 of the core 1. Next, wire rod 2
The winding chuck 18, which is not gripped and is in an open state, is moved back to a position where it does not interfere with the wire rod 2 and the core 1 by the winding chuck front and rear drive unit 25, and is preliminarily moved by the winding chuck up and down drive unit 22. The set amount is vertically lowered to the regripping and cutting position D, and the winding chuck 18 is moved forward to a position where it can grip the wire 2 by the winding chuck front and rear drive unit 25, and then the winding Close the chuck 18,
Grip the wire 2, re-grip it, and cut it. At the regripping/cutting position D, the winding chuck 18
grips the upper part of the drawer chuck 30 for a certain length. Next, the cutter device 37 is advanced by the cutter front and rear portions 38 to cut the wire 2. The cutting position with the cutter device 37 is between the winding chuck 18 and the drawer chuck 30.
The wire rod 2 is cut from 8 to the minimum length necessary for passing the wire rod 2 through the core 1, and moreover, is always accurately cut so that the length from the winding chuck 18 is constant.

Next, as described above at the regrasping/cutting position D,
The winding chuck 18 holding the wire 2 is connected to a winding chuck vertical drive section 22 and a winding chuck rotation drive section 1.
9, the winding chuck 18 rises and rotates from the regripping/cutting position D to the recognition position A while rising in the vertical direction. At this time, tension is applied by pushing the wire 2 with the tension sesame 78 of the tension device 75, thereby tightening the winding around the core 1 and giving the wire a curl that makes it easy to wind.

In this way, the operation of winding one turn of the wire 2 around the core 1 is completed. This can be achieved by repeating the above operations depending on the required number of windings, but as the winding progresses, the wire 2 is wound around the core 1, and the tip of the wire 2 is cut and a certain length is discarded. becomes shorter. Therefore, the length of the wire 2, which becomes shorter each time one turn of winding progresses, is calculated, and the amount of upward and downward movement of the winding chuck vertical drive unit 22 and drawer chuck drive unit 31 is set according to the number of turns. ing.

Wire guiding operation: In order to recognize the tip of the wire 2 and enable the winding chuck 18 to insert the wire, the first guide member 80 advances diagonally from the front at the same time as the winding chuck 18 rotates 180 degrees, and the winding loop 2a ( (Fig. 19) is pushed backwards. The winding chuck 18 passes the tip of the wire rod 2 through the winding hole and pulls out the drawer chuck 30.
When gripped, the wire rod 2 is released and retreated, but at the same time as this retreat, the first guide member 80 moves forward as a second step to the position where it could not advance due to interference with the winding chuck 18. Simultaneously with this second stage operation, the second guide member 81 moves forward obliquely from above, resulting in the state shown in FIG. 20. When the operations of the first and second guide members 80 and 81 are completed, the guide slit 82 formed between the tips thereof becomes at a distance necessary to guide the wire 2 to a predetermined position. For example, the interval is about twice the outer diameter of the wire 2. Simultaneously with the operation of these guide members 80 and 81, the XY movable table on which the core holding part 12 is mounted is set so that the relationship between the tips of the guide members 80 and 81 and the position of the winding hole 3 of the core 1 is at a predetermined position. 14 moves. When the drawer chuck 30 is lowered, replaced with the winding chuck 18, and raised, the winding has been completed and the first and second guide members 8
0,81 returns.

The entire operation is completed as described above, but the action of the line guide will be further explained with reference to FIGS. 30 and 31. The line guide operates as described above, but provides three functions: First, in the winding operation, when the drawn wire rod 2 is wound by the rise and rotation of the winding chuck 18, the wire rod 2 becomes free, so that the winding loop 2a may fall forward depending on the wire twist. There are cases where the wire cannot be wound at the specified position and the wire is wound as shown at 2a' in FIG. 31, but this can be prevented by regulating it with the first guide member 80 as shown in FIG. 30. can. Next, by restricting the wire rod 2 to be sandwiched between the guide members 80 and 81 by the guide slit 82, the wire rod 2 can be wound accurately at a predetermined position in the winding hole 3 of the core 1. Furthermore, XY
By sequentially moving the movable table 14 in the Q direction (Fig. 30) by the thickness of the wire rod 2 for each winding, the wires can be wound in an array as shown in the figure.
In this case, since the core holding part 12 is fed in pitches, the winding chuck 18, the drawer chuck 30, etc. can remain fixed, which simplifies the structure. Further, the first guide member 80 is
As mentioned above, the winding chuck 18 is advanced in advance to a position where it does not interfere with the winding chuck 18, and after the winding chuck 18 has retreated, it is further advanced, which is a two-step operation. It is possible to advance to the target position in a shorter time than when operating the stroke. Therefore, the wire rod 2 can be guided reliably.

In the above embodiment, the wire tip is recognized and the wire tip is cut in order to improve the reliability of the winding, but if it is not necessary, for example because the core hole is large, it may not be used. It's okay. Further, although the guide operation is performed by an air cylinder, other driving means may be used. In short, the present invention can be applied to any device in which the wire is passed through one of the holes in the core by a gripping means, pulled out to the other by a drawer chuck, and then passed from one of the holes again by the gripping means.

Effects of the Invention The winding device of the present invention has the advantage that the winding device can be regulated and the structure is simple.
