Abstract

PURPOSE:To reduce the number of times of recognition of the position of the fore end of a wire material to the requisite minimum and thereby to shorten a time required for winding by a method wherein the position of the fore end of the chucked wire materials is recognized only twice in initial operations and the position of a core is corrected in accordance with the result of recognition. CONSTITUTION:The position of the fore end of a wire material 2 is recognized at a position A of recognition by a TV camera 8, and the amount of positional deviation is compensated by a moving table where on a core holding unit is mounted. This operation of compensation is conducted only twice, that is, at the times when the wire material 2 is brought from a wire supplying-holding- cutting unit by a winding chuck 18 to be inserted initially at the start of winding, and when the second wire insertion is conducted after the material is cut initially by a cutter device, and thereafter said operation is not conducted. On and after the third time, the winding chuck 18 is passed through the position A of recognition without stopping. Consequently, a winding tact is shortened, and thus a time required for winding for one core 1, for instance, can be reduced by 20-30%.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a winding method and apparatus for winding a wire around a toroidal core of a video head, computer magnetic head, or the like.

Conventional structure and its problems Conventionally, a toroidal winding machine has been used for the @ wire to the hollow hole. A toroidal winding machine winds wire by winding the wire onto a pre-tightened spool, and the spool and shuttle rotate a hollow hole in the material to be wound.
Since the spool and shuttle need to rotate through the hollow hole in the object to be wound, there is a limit when the hollow hole becomes small.
It is impossible to wind the wire in a hollow hole with a diameter of 1w5kJ or less.

It is extremely thin due to its age, and the hole size is 0.25 x Q, 3 m.
- It is considered to be small and technically difficult to automate, so it relies on manual labor 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. 57-999999).
In other words, the 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 pull-out chuck and pulled out downward.The drawn-out wire is again grasped by the winding chuck and removed from the core. The process of winding the wire around the core and passing it through the winding hole in the core is repeated. However, due to the tip position shift due to bending of the wire, the core's il [
The wire may not be inserted smoothly into the winding hole. - Therefore, each time the wire is wound, the position of the tip of the wire is recognized with a television camera, and the position of the core is corrected according to the deviation before the wire is threaded through. As described above, since a recognition step is required every time, there is a problem that the winding tact becomes long.

In addition, conventionally, in each winding cycle, J'ζ, winding cha,
When the wire is pulled out from the chuck and replaced by one side, 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 for winding the wire in the winding hole is an ultra-fine wire with low rigidity, but once the wire is gripped by the drawer chuck 7, it may bend, and if it is gripped repeatedly, the tip of the wire may become fatigued. The length of the tip may vary due to damage or slippage, making it impossible to thread the wire through. To prevent this, the 6-wire rod is cut using a scissor-like cutter.

However, when cutting with scissors, the wire ends up escaping to the tip #1III of the scissors, causing a bend in the wire 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 A first object of the invention is to provide a winding method that can reduce the winding time by minimizing the number of times the position of the tip of the wire is recognized.

The second invention is characterized in that there is less variation in the tip position of the wire, and the number of times the tip position is recognized is increased by 9 degrees in each winding cycle.
It is an object of the present invention to provide a winding device that can reduce the number of wires.

Structure of the Invention The wire winding method of the present invention includes inserting a wire into a hole of a core from one side using a gripping means, pulling out the inserted wire with a pulling means, and gripping the pulled-out wire again with the gripping means. The vicinity of the tip of the wire is cut at a predetermined distance from the gripping means, and the wire is again inserted into the hole of the core using the gripping means! ! In the wire method, before the wire is first held by a gripping means and passed through the hole in the core, after the first wire is inserted and the above-mentioned cutting is performed, and before the second @th Φ wire is inserted. In this method, the position of the tip of the wire held by the gripping means is recognized by the recognition means only twice, and the misalignment of the core is corrected according to the recognition results. Recognition and correction are not performed after the third time.

In this way, the winding tact is shortened compared to the case where the recognition is performed only the first two times, compared to the case where the recognition is performed every time. The most υ1 line 1. Twice with n people [With 1 Lineura people, the tip position of the wire cannot be determined accurately, and recognition and correction are necessary. However, from the third time onwards, the accuracy of the cutting means is increased so that the position of the wire end after cutting remains constant, so that the position of the end of the wire remains the same as the second time. Therefore, if recognition and correction are performed the second time, line insertion can be performed from the third time onward without recognition and correction.

The wire winding device of the present invention includes a fixed blade having a V-shaped wire guide portion as a wire cutting means, and a wire rod that is pulled up to the bottom of the V-shaped wire guide portion of the fixed blade and cut. It consists of a movable blade.

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 constant at the bottom position. For this reason, the tip of the wire can be recognized and the positional deviation of the core can be detected by JIl.
Even if the operation is t+L', line insertion can be performed reliably.

■Flip the core 1 with the holding part 12, and turn the other winding← ■-Take out core l.

FIG. 26 schematically shows the overall operation, and the explanation 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 unit 91 is rotated to the position shown by the solid line in FIG. 25, the take-out chuck 93 is lowered, grips the core l 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 l 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 part 12 moves in the Y-axis direction toward the position where winding is performed. At the same time, the core transfer section 91
rotates and returns to the top of the gold smell 88 (as shown by the chain line in FIG. 25! 3).

Then, the winding-completed core l held by the take-out chuck 93 is placed on the jig 88. Then, the supply chuck 92 descends and grips a new unwound core 2. When the gripping is completed, the core transfer section 91 rotates to the solid line position in FIG. 25 and waits before the winding of the previously supplied core I is completed.

Core holding t, L1 with the above-mentioned core 1 placed on top and heading towards the winding position
(No. 12 pauses at a position that can be recognized by the left TV camera. At this point, read the center position of the winding hole 3 of the core l with the left TV camera and store the core holding part at the 0 winding position 1. In other words, during one winding, the core l
is reversed once as described above, but during the take-out operation, core 1 with completed winding is replaced with the initially supplied core l.
In order to obtain the same state as above, the core holder 12 is rotated to invert it again. Thereafter, the XY moving table 14 carrying the core holder 12 moves to the position where the core 1 is taken out by the aforementioned taking-out chuck 93.

Wire supply operation, wire end processing operation, etc.: As shown in Fig. 27, the wire 2 from the winding bobbin 53
The wire is initially safed by hand to the wire supply gripping and cutting device 60. This state becomes the state shown in FIG. 28(A). Next, as shown in Fig. 27 or Fig. 28 (8>), the wire is 2 grasp the
And the tip of the wire is a predetermined length l (first
The wire rod 2 is cut by the cutting element 63 of the wire supply cutting and gripping device 60 as shown in FIG. 9(B)). Thereafter, the horizontal, vertical, and rotational movements of the winding chuck 18 are combined to move the tip of the wire 2 to the recognition position of the TV left camera, and the tip position of the wire 2 is recognized and stored.

This recognized wire rod tip position is compared with the position of the winding hole 3 of the core l recognized in the core supply process described above, and the winding hole 3 is
A difference is calculated in the positional relationship in which the tip of the wire rod 2 passes, and the position of the core l 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 I is recognized. The core holding part 12 is connected to the winding hole 3 by
1& further moves, so it does not interfere with the winding chuck 18 when recognizing the tip of the wire 2. This makes it possible to share the TV left camera. Furthermore, until now,
The wire 2 remains connected to the wire supply device 52.

Next, as shown in FIG. 17 or FIG.
The wire is passed through the winding hole 3, its tip is gripped by the pull-out chuck 30, and the length required for winding (preset according to the number of windings) is pulled out downward. Grip the wire rod 2. This stops the wire from being pulled out from the wire supply device W52.

After this, as shown in Fig. 27 (■), with the wire 2 drawn out, the winding operation is repeated for the set number of turns on one winding position (■) of the winding hole 3 of the core l (Fig. 1c). Details will be explained 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 l, and the wire rod 2 is sucked by vacuum suction using the suction vibrator 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 [phase] and Fig. 2'8 (D), the wire 2 at the other end is wound at the other winding position lb of the core l. , the core l is reversed by the core holding part 12, and the winding chuck 18 moves the wire rod 2 to the wire supply gripping and cutting device 60.
At this time, the other end of the wire rod 2 is cut. At this time, since the direction of the tip of the wire rod 2 is different from the direction of the initial wire supply, the wire supply gripping and cutting device 60 is
63.64 and a gripping element 61.62. The winding chuck 18 grips the other end of the wire rod 2 and moves toward the position where the tip of the wire rod 2 is recognized. Move the circle downwards as if it were a positive image. When the recognition position is reached, Fig. 27 O@ and Fig. 28 (E
), 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 connected to the winding bobbin 53 and that the winding hole is not recognized.The 0 winding hole position memorizes the initial position. Therefore, this information is used to correct the difference caused by inversion. When the set number of turns is completed, the tip of the wire 2 faces the wire processing hole 4 of the core I and is sucked in by the suction pipe 15 in the same manner as described above, and the winding at the other end is completed.

Winding operation: FIG. 29 shows the continuous operation of the winding chuck 18, and the main states of the winding chuck 18 are as follows:
A is the recognition position, B is the wire threading preparation position, and C is the wire threading position! ,
D is defined as the regripping/cutting position. T! line chahuku 18
goes through states A, B, C, and D, and completes the winding. The operation of the line guide (FIGS. 21 and 22) will not be discussed here, but will be described in detail later. In the recognition position IA, the tip of the wire rod 2 held by the winding chuck 18 is read by the recognition TV camera 8, and the amount of positional deviation is measured by the xy
After operating the moving table 14 and making corrections, the winding chuck 18 is rotated by 180 degrees by the winding chuck rotation unit 19 to reach the wire threading preparation position B. This recognition and correction operation is performed by transferring the wire 2 from the wire supply gripping and cutting device 60 to the winding chuck 18.
This is only done when you bring it in and when you insert the line for the second time, and not at other times! In order to stop the rotating operation of the one-wire chuck 18 at an accurate position every time, the tip of the winding chuck is directed downward in the vertical direction, and is aimed at the center of the winding hole 3 of the core l or the target through which the wire 2 is passed. The zero-order winding chuck 18 that coincides with the vertical line of the position is lowered by the winding chuck vertical drive unit 22, and the wire 2 is inserted into the winding hole 3.
The winding chuck 18 reaches the wire threading position WC. At the wire threading position C, as shown in No. 30rjgJ, the tip of the wire 2 passes through the winding hole 3 of the core l and protrudes below the core l by a length that can be gripped by the drawer chuck 30. While gripping the tip of the wire rod 2, the winding chuck 18 opens and releases the wire rod 2.

Next, the drawer chuck 30 grips the wire 2 and lowers it by a preset amount in the vertical direction. 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 descends, the wire rod 2 gripped by the drawer chuck 30 is in a state with almost no slack in the vertical direction to the winding hole 3 of the core l. The winding chuck [8] is in the open state and the wire rod 2 and core 1 are moved by the winding chuck front and rear drive unit 25
The winding chuck vertical drive unit 22 lowers the winding chuck by a preset amount in the vertical direction, and the winding chuck front and rear drive unit 25 moves the winding chuck 1
8 moves forward to r enough to grip the wire 2, closes the winding chuck 18, grips the wire 2, and reaches the regripping/cutting position. 0 Gripping/cutting value! In D, as shown in FIG. 29, the winding chuck I8 grips the upper part of the drawer chuck 30 for a certain length.Then, the cutter device 37 is advanced by the cutter front and rear parts 38 to cut the wire rod 2. do. The cutting position with the cutter device 37 is the 32nd
As shown in the figure, the winding chuck 18 and the drawer chuck 3
0, and is the minimum length necessary for passing the wire 2 from the winding chuck 18 through the 2 aluminum, and moreover, the length from the winding chuck 18 is always accurate and constant. Cut it so that it looks like this.

Next, as described above (, wire rod 2
The winding chuck I8 that grips the winding chuck rotates with the winding chunk vertical drive unit 22! 19, it ascends vertically from the regrasping/cutting position to the recognition position A.
The wire-wound chuck 1B rises and rotates. At this time, tension is applied by pushing the wire 2 with the tension sesame 78 of the tension device ff175, 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 rod 2 around the core l is completed. This can be achieved by repeating the above operation depending on the required number of turns, but as the winding progresses,
The wire rod 2 is wound around the core L, and the tip of the wire rod 2 is cut off and a certain length is discarded, so the length of the wire rod 2 becomes shorter.

Therefore, the length of the wire rod 2, which becomes shorter each time the turn winding progresses, is calculated, and the amount of upward and downward movement of the winding chuck vertical drive section 22 and the drawer chuck drive section 31 is set according to the number of turns. ing.

Wire guiding operation: Since the winding chuck 18 recognizes the tip of the wire 2 and allows the wire to be inserted, the first guide member 80 advances diagonally from the front at the same time as the 180° rotation, and the winding loop 2a ( (Fig. 23) to push it backwards 1
When the winding chuck 18 passes the tip of the wire rod 2 through the winding hole and grips it with the drawer chuck 30, the wire rod 2 is released and moves back and forth. At the same time, the first guide member 80 moves the winding chuck As a second stage operation, the robot advances to a position where it could not advance due to interference with 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, 81 are completed, the guide slit 82 formed between the tips of the first and second guide members 80, 81 has a spacing necessary to guide the wire 2 to a predetermined position. If kept, the distance is about twice the outer diameter of the wire rod 2. Simultaneously with the movement of these guide members 8G and 81, the core holding part 12 is moved in the XY direction so that the relationship between the tips of the guide members 8G and 81 and the position of the winding hole 3 of the core 1 is at a predetermined position. The stand 14 moves. Bow: jQg
When the chuck 30 descends, grasps the winding chaff 18 again, and ascends, the winding has been completed, and the first and second guide members 80 and 81 return to their original positions.

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 by the TV camera 8 at the recognition position ifA, and the positional deviation amount is corrected by the XY moving table 14 equipped with the core holding part 12. The wire rod 2 is transferred from the cutting device 260 to the winding chuck 18
This is done only twice: when the wire is brought in by the cutter device 37 and inserted for the first time, and when the wire is inserted for the second time after the cutter device 37 first cuts it. 7 and 18 do not stop at the recognition position A and are allowed to pass through without stopping. Therefore, the winding tact is shortened, for example, by 1
The time required for winding each core 1 can be reduced by 20 to 30%. Il's first line insertion and second line insertion are
The position of the tip of the wire 2 is not accurately determined and requires recognition and correction. However, if the accuracy of the cuff-coupling device 37 is ensured so that the tip position of the wire rod 2 after cutting is kept constant, the tip position of the wire rod 2 when it is first cut is recognized and the position of the core l is corrected. If this is done, the line insertion can be performed from the third time onwards in almost the same way as the second time.

As shown in FIGS. 30(A) and 30(B), the cutter device 37 has a V-shaped wire guide portion 40a in which the wire 2 has a fixed blade 40.

), the movable blade 43 pulls the wire 2 up to the angular bottom of the V-shaped wire guide portion 40a, and cuts the wire 2 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.

Note that in the above embodiment, the wire tip recognition was not performed on the winding on one side of the core 1 until the end of the winding.
The wire tip may be recognized and corrected at a rate of 100% to ensure reliable wire insertion. In addition, the first two wire tip recognition steps may be unnecessary if the core hole size is large or if the cutting position of the wire tip is precisely adjusted. Although the movable blade is used as a blade and the retracting blade is a movable blade, both may be movable or the above may be reversed.

Effects of the Invention The winding method of the present invention has the advantage that the winding time can be shortened while ensuring wire insertion by performing the necessary minimum recognition of the wire rod tip position 1.

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 position of the tip is recognized can be reduced.
