Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a winding device for winding a wire around a toroidal 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 the diameter 1
It is impossible to wind the wire into a hollow hole with a diameter of less than mm.
The wire diameter for winding the video head is 0.03mm to 0.05mm.
The holes are extremely thin, with hole dimensions as small as 0.25 mm x 0.3 mm, making it technically difficult to automate the process, and the process had to be done by hand or using simple jigs and tools.

Therefore, we proposed the following device as a device that can automatically perform this difficult winding process (Japanese Patent Application No. 1983-
No. 999999). That is, a wire is passed through the winding hole of the toroidal core from above using a winding chuck, and the wire that protrudes from the core is grasped by the drawer chuck and pulled out downward.The drawn wire is grasped again by the winding chuck and attached to the core. The process of winding the wire and passing it through the winding hole in the core is repeated. However, the core may not be inserted smoothly into the minute winding hole due to a shift in the tip position due to the bending of the wire. Therefore, each time the wire is wound, the position of the tip of the wire is recognized using a television camera, and the position of the core is corrected according to the deviation before threading. As described above, since a recognition process is required every time, there is a problem that the winding tact becomes long.

Furthermore, conventionally, in each winding cycle, when the wire is taken out from the winding chuck and replaced from the drawer chuck, the wire is cut to a predetermined length from the winding chuck. This is due to the following reason. In other words, the wire used to wind the wire in the winding hole is a very thin wire with low rigidity, but once the wire is gripped by the pull-out chuck, it may bend, and if it is gripped repeatedly, the tip of the wire may be damaged due to fatigue. This is to prevent the tip from slipping and causing variations in the length of the tip, making it impossible to thread the wire through. The wire is cut using scissor-like cutters. However, when cutting with scissors, the wire ends up escaping toward the tip of the scissors, causing the wire to bend and causing variations in the position of the tip of the wire after cutting. As a result, it may become impossible to thread the wire, and the above-mentioned recognition is required each time.

OBJECTS OF THE INVENTION An object of the present invention is to provide a winding device that can reduce the number of times the tip position is recognized by cutting the wire so that variations in the tip position are reduced in each winding cycle.

Structure of the Invention The wire winding device of the present invention includes a fixed blade having a wire guide section with a wire cutting means opened in a V-shape, and a wire rod that is pulled to the bottom of the V-shaped wire guide section of the fixed blade. It is constructed with a blade that can be cut using the same method.

In this way, the wire is pulled up to the bottom of the V-shaped wire guide section and cut by the movable blade, so the wire is cut while being restrained at the bottom so that it cannot escape in any direction. That will happen. Therefore, the position of the tip of the wire rod after cutting is always the same as the bottom position. Therefore, even if the operation of recognizing the tip position of the wire and correcting the positional deviation of the core is omitted, the wire can be inserted reliably.

are installed side by side. These supply chucks 92
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 there.

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.

At one winding position of 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. 26 shows an outline of 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. 25, 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 to the top of the jig 88 (the state shown by the chain line in FIG. 25). 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 2. 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. 25 and waits.

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, the center position of the winding hole 3 of the core 1 is read with the TV camera 8 and stored. When the core holder reaches the winding position, winding is performed. During winding, the core 1 is reversed once as described below, but in order to take out the core 1 after winding is in the same state as the initially supplied core 1, the core holder 12 is turned over. 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. 27, 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. 28A. Next, as shown in FIG. 27 or FIG. 28B, 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. 19B) 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. 27 or FIG. 28C, 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 held by the drawer chuck 30, and the winding chuck 18 is turned over. 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. 27, the wire rod 2 is wound over one winding position (FIG. 1C) of the winding hole 3 of the core 1 by repeating the winding operation 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, as shown in FIG. 27 and FIG. Then, 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. At this time, since the initial direction of the wire supply and the direction of the tip of the wire rod 2 are different, the wire supply gripping and cutting device 60 is provided with two cutting elements 63 and 64 and gripping elements 61 and 62. The winding chuck 18, which grips the other end of the wire 2, moves toward the position where the tip of the wire 2 is recognized.
At this time, the winding chuck 18 moves below the core 1 in a circular manner so that the wire 2 is not wound around the core 1 unnecessarily. When the recognition position is reached, the 27th
As shown in the figure and FIG. 28E, the tip of the wire 2 is recognized and the winding operation begins. At this time, the difference from the operation on the one end side described above is that the wire rod 2 is attached to the winding bobbin 5.
3, 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 is brought into contact with the wire processing hole 4 of the core 1 and sucked in by the suction pipe 15, as described above, and the winding of the other end is completed.

Winding operation: Figure 29 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 21 and 22) 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. This recognition and correction operation is carried out by the above-mentioned line supply gripping and cutting device 6.
This is only when the wire rod 2 is brought from 0 with the winding chuck 18 and when the wire is inserted for the second time.
Not done at other times. The winding chuck 18 is rotated by a winding chuck rotating pulse motor 20 so that it stops at an accurate position each time. When rotated by 180 degrees, the tip of the wire rod 2 held by the winding chuck 18 will point downward in the vertical direction, and will align with the center of the winding hole 3 of the core 1 or the vertical line at the target position through which the wire rod 2 will pass. . 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. Wiring position C
As shown in FIG. 30, 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 with the drawer chuck 30. While gripping the tip, 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 previously removed by the winding chuck up and down drive unit 22. The set amount is lowered in the vertical direction, and the winding chuck 18 is lowered by the winding chuck front and rear drive unit 25.
After moving forward to a position where the wire rod 2 can be gripped, the winding chuck 18 is closed, the wire rod 2 is gripped, and the gripping/cutting position D is reached. At the regripping/cutting position D, as shown in FIG. 29, 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, as shown in FIG. The wire is cut to the minimum length and always accurately 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 rod 2 is connected to a winding chuck vertical drive section 22 and a winding chuck rotation drive section 1.
9, the winding chuck 18 is raised and rotated vertically from the regripping/cutting position D to the recognition position A. At this time, tension is applied by pushing the wire 2 with the tension separator 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 ( 23) to the rear. 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 moves back and forth, but at the same time as this movement, the first guide member 80 moves forward as a second stage operation to the position where it could not move forward 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. 24. 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.

Although the overall operation is completed above, the recognition/correction and the operation of the cutter device 37 will be described in further detail.

The tip position of the wire rod 2 is recognized at the recognition position A by the TV camera 8, and the amount of positional deviation is corrected by the XY moving table 14 equipped with the core holding part 12. The wire rod 2 is brought from the device 60 by the winding chuck 18 and the wire is inserted for the first time, and the wire is first cut by the cutter device 37 and the wire is inserted for the second time. do not have. From the third time onwards, the winding chuck 18 is not stopped at the recognition position A, but is allowed to pass through as it is. Therefore, the winding tact is shortened, and for example, the time required for winding one core 1 can be reduced by 20 to 30%. In the first line insertion and the second line insertion, the tip position of the wire rod 2 is not accurately determined and requires recognition and correction. However, if the precision of the cutter device 37 is ensured so that the tip position of the wire rod 2 after cutting is kept constant, the position of the tip of the wire rod 2 when it is first cut is recognized and the position of the core 1 is corrected. If this is done, the line insertion can be performed from the third time onward in almost the same way as the second time.

The cutter device 37 moves forward until the wire 2 enters the V-shaped wire guide portion 40a of the fixed blade 40, as shown in FIGS. 30A and 30B, and then, as shown in FIGS.
As shown in D, the movable blade 43 is a V-shaped wire guide part 4.
The wire 2 is pulled up to the angular bottom of 0a, and the wire 2 is cut here. Therefore, unlike the conventional case where a scissor-shaped cutter is used, the wire rod 2 is cut while being restrained so that it cannot escape in any direction. Therefore, the position of the tip end of the wire rod 2 after cutting is always constant at the bottom of the V-shaped wire rod guide portion 40a. Therefore, even if the recognition of the wire tip position for each winding is omitted as described above, the wire can be inserted reliably.

In the above embodiment, after the first two wire ends are recognized for the winding on one side of the core 1, the wire ends are not recognized until the end of the winding.
For example, the wire tip may be recognized and corrected once every few times to ensure wire insertion. Further, the first two wire tip recognitions may be unnecessary if the size of the core hole is large or by precisely adjusting the cutting position of the wire tip. Furthermore, although the blade having the V-shaped wire guide portion is a fixed blade and the retracting blade is a movable blade, both may be movable or vice versa.

Effects of the Invention The winding device of the present invention has the advantage that there is little variation in the position of the tip of the cut wire, and the number of times the tip position is recognized can be reduced.
