Description

The present invention relates to a winding for automatically applying a winding to a minute winding hole of a magnetic core used in a magnetic head of a video tape recorder (VTR), for example. Regarding the machine.

[Prior Art] FIG. 17 shows an example of a magnetic head 1 for a VTR, in which a magnetic core 2 in which a pair of half cores 2a and 2b are joined is fixed to the top of a base plate 3 and between the half cores 2a and 2b. A wire 5 is wound around the winding hole 4 formed in. In this magnetic core 2, the winding hole 4 is set to be close to the gap 6 and its size is set to be small, whereby the magnetic characteristics are improved. As a result, the winding hole 4 is located above the winding portion 7 on the side surface of the magnetic head 1, and the winding is inclined so as to descend toward the outside as shown in FIG.

The magnetic head 1 as described above is becoming smaller and smaller due to the higher density of information recording, and in recent years, it is 0.35 × 0.3 mm.
It is required that the winding hole 4 of □ be provided with a winding of 0.01 mmφ about 5 to 10 times. Such work is extremely precise work, which has been conventionally performed manually, but it requires skill and is inefficient, so recently its mechanization has been attempted and various devices have been proposed.

The one described in Japanese Patent Laid-Open No. 61-259515 is an example thereof. This is a rotatable core holding means for holding the core at a predetermined position and a wire insertion for inserting the wire into the winding hole of the core. And a winding means for winding the drawn wire around the outside of the core.

In the winding means, a swivel chuck having an opening / closing claw is slidably installed along a swivel arm that is swivelable about a core holding means along the swivel arm. The one end is held by the above-mentioned turning chuck, and the turning arm is turned to wind the core.

[Problems to be Solved by the Invention] However, in the conventional technique as described above, it is necessary to rotate the revolving arm each time winding is performed, and therefore it takes time to wind the winding arm, and the improvement in efficiency is insufficient. There was a task to be done.

Also, in such a winding device, a holding claw that can be freely opened and closed is provided to hold the wound wire in the wound state, but the abutting portion at this tip can sufficiently hold the wire. However, there was also a problem such as rewinding of the wire.

The invention according to the first aspect is made in view of the above-mentioned circumstances, and a wire pushing device and a wire drawing device are provided on both sides of the magnetic core, respectively. The winding work can be speeded up without turning around, and the guide die can be eccentrically attached to the rotating member to guide the wire on both sides of the magnetic core with one guide die An object of the present invention is to provide a winding machine capable of moving a guide die in accordance with various winding work.

The invention described in claim 2 is made in view of the above circumstances, and in addition to the above effects, the wire wound around the winding hole of the magnetic core is surely pressed without being damaged during the winding step, and the winding step is performed. An object of the present invention is to provide a winding machine capable of smoothing.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention comprises a pair of half cores joined together in the first claim.
A holding base that holds a magnetic core around which a wire is wound around each half core through a winding hole formed between these half cores so as to be rotatable in a horizontal plane, and holding bases on both sides of the holding base. It is installed so that it can be moved back and forth, and it is installed on the opposite side of the pushing device with respect to the holding base, and a pair of pushing devices that push the tip of the wire into the winding hole of the magnetic core by moving forward while gripping the wire. A winding machine for a magnetic head comprising a pair of wire drawing devices, wherein a rotating member is provided in the vicinity of the holding table so as to be movable toward and away from the holding table and rotatable in a horizontal plane. A guide die is attached to the lower part of the member so as to be eccentric with respect to the rotation center of the rotating member, and a guide hole having a taper hole for guiding the tip of the wire to the winding hole is formed in the guide die. The size of the eccentricity of the mounting position of the guide die can be made to be desired by the eccentric rotation of the guide die both in the vicinity of the opening on one side and in the vicinity of the opening on the other side of the winding hole of the magnetic core. It is formed by.

Further, in the invention according to the second aspect, a wire clamp, which comes into contact with the side surface of the magnetic core and prevents the wire wound around the magnetic core from being loosened, can be freely moved toward and away from the magnetic core. A wire holding member having flexibility is attached to the abutting end of the wire clamp.

[Operation] In the winding machine configured as described above, the pushing device on one side is moved forward to guide the wire tip through the guide member into the winding hole, and the pushing device is further moved forward to push the winding hole. ,
After pulling out the tip with the other pulling device, the wire is wound half around the half core when the holder is rotated half a turn. Here, when the tip of the sum is replaced with the pushing device on the other side and the pushing device is moved forward and is pulled out by the pulling device on the one side, the wire is wound around the half core once. By repeating this in sequence, a large number of windings are applied. In the above steps, the winding is performed by rotating the holding table, so that the winding is performed quickly.

The wire once wound is wound and tightened by a pushing device and a drawing device, but when these are loosened, the tightening is not loosened by being held by a wire clamp having a flexible member attached to the tip. Moreover, since the guide die can be eccentrically attached to the rotating member and the wire can be guided on both sides of the magnetic core by one guide die, the holding base for holding the magnetic core can be rotated, and both sides of the holding base can be rotated. When using the winding machine configured to wind the wire around the winding hole of the magnetic core by using the wire pushing-in device and the pulling-out device provided, by rotating the guide die, which side of the winding hole is formed on the magnetic core. One guide die can be used even when passing the wire through. In addition, the guide die is eccentrically attached to the rotating member, and the radius of rotation thereof is extremely small, so that the guide die can be moved quickly, and as a result, the wire pushing device and the wire drawing device are provided on both sides of the holding table. Even in a winding machine in which winding is performed quickly, the movement of the guide die easily follows the winding process.

As will be described later, the winding work is one half core
When moving from 2a to the other half core 2b, both half cores 2
If the connecting wire 5a (see FIG. 18) that connects the windings a and 2b is located in the winding hole 4, it will hinder the subsequent winding work, so connect the connecting wire 5a to the lower end of the winding hole 4. It is to be located in the section.

Furthermore, in addition to the above-mentioned device, this wire winding machine also has a wire feeding device, a device for cutting the wire to an appropriate length, a device for exchanging a wound magnetic core with a new magnetic core, and other accessories. The target device is provided.

Hereinafter, a process of winding a wire with the winding machine configured as described above will be described with reference to FIGS. 12 to 14.

For simplification of the description, the process of supplying the wire 5 and winding start is omitted, and the wire 5 is one half core.
2a will be described starting from a state in which the winding is started from above the winding hole 4 and is wound several times.

The wound wire 5 is pressed by the wire clamp 14 on the side surface of the magnetic core 2 so that the wound portion will not be loosened even if the wire 5 is loosened.

Then, in the state in which the pushing device 50 grips the tip of the wire 5, the guide die 29 in the guide device 20 is attached to the base plate 3.
It is made to stand by above between the pushing device 50 and. Pushing device
After the backward movement of 50, the elevating drive cylinder 36 of the guide device 20 operates to lower the guide die holding member 26 and stop at a predetermined position (see FIG. 12 (a)). In the pushing device 50, the hand guide 62 is directed toward the holding base 10 and the hand clamp 63 holds the wire 5 in a state of being separated by a predetermined distance behind it and stands by, and the drive motor 47 operates in that state. The pushing portion 57 advances toward the holding table 10 ((b) in the figure).
reference). When the pushing portion 57 further advances, the hand guide 62
Is restricted from moving by a stopper provided in the wire guide device 20, and only the hand clamp 63 moves forward to push the wire 5 through the V-shaped groove 73 of the hand guide 62. This allows the tip of the wire to pass through the taper hole 42 of the guide die 29
It is guided to 43, penetrates the guide hole 44, and protrudes to the other side from the winding hole 4 of the magnetic core 2.

On the other side of the magnetic core 2, the drawing device 80 stands by in a predetermined state. That is, the drawer motor substrate 82 is moved forward by the operation of the drive motor 47 (jig cylinder 80 a), the suction cylinder main body 85 is moved forward by the suction cylinder main body 85, and the taper portion 88 of the suction nozzle 86 is moved to the arm of the testion hand 84. The arm 89 is pushed leftward and rightward by engaging with the slope 91 of 89, and the tip of the suction nozzle 86 faces the magnetic core 2 (see FIG. 13A). Then, the pushed wire 5 is sucked by the suction nozzle 86 and is slit.
It is pulled inward from 94 (see Fig. 12 (b) and (c)). In this state, the nozzle cylinder 87 contracts, the arm 89 is closed, and the wire 5 is gripped (see FIGS. 12 (d) and 13 (b)). Wire 5 is a suction nozzle
The position is always kept constant because the arm 86 holds the position evenly in the vertical direction by 86 and is evenly closed from the left and right while being sucked and tensioned.

Thereafter, in the wire guide device 20 and the pushing device 50, the die opening / closing cylinder 41 and the hand opening / closing cylinder 75, respectively.
Is operated to open the guide die 29, the hand guide 62 and the hand clamp 63, and the lifting cylinders 36 and 53 are operated to allow the cylinders to move upward (see FIG. 12 (e)).

At this time, the side surface of the magnetic core 2 is held by the wire clamp 14, and the holding base 10 is tilted by about 45 degrees so that the side on which the wire 5 is held becomes far (Fig. 13 (C), 14th). (See Fig. (A))
82 is retracted, the wire 5 is pulled out from the winding hole 4, a certain tension is applied to the wire 5, and the wire 5 is wound around one surface of the magnetic core 2 (see FIG. 13 (d)). In this step, since the magnetic core 2 is inclined, the wire 5 bends so as to form an obtuse angle at the corner of the winding hole 4, and thus the wire 5 smoothly moves at the corner of the winding hole 4 of the magnetic core 2. The movement of the wire 5 is sufficiently tightened, and the wire 5 is prevented from being rubbed at the corner of the winding hole 4 and broken.

The wire clamp 14 is released while the wire 5 is strained, and the drive shaft 1 of the first wire holding device 100 is released.
01 is rotated, the arm 102 descends to a predetermined position, and presses the wire 5 from above as shown in FIGS. 14 (b) and 15, where the holding table 10 rotates in the reverse direction and rotates approximately 135 degrees. (See Figure 13 (e) (f)). This allows the wire 5
Is wound so as to be inclined so that the outside is low on the surface of the magnetic core 2. At this time, the magnetic core 2 is sequentially tilted while the wire 5 is strained, so that the wire 5 is sufficiently tightened in the same manner as described above. When the magnetic core 2 returns to the reference position, the wire 5 is wound once, and the wire clamp 14 is closed to fix the wound wire 5 to the side portion of the magnetic core 2.

When one winding process is completed as described above, next, winding is performed by the pushing device 50 and the withdrawing device 80 on the side different from the previous one. That is, in FIG. 12 to FIG. 14, in the state in which the left side withdrawing device 80 is retracted, the pushing portion 57 of the left pushing device 50 is brought close to the withdrawing device 80 side with each blade 64, 65 open. , Lowered. By closing the blades 64 and 65, the wire 5 is held by the hand clamp 63 while being guided by the hand guide 62 (see FIG. 14D). Next, the stepping motor 60 of the pushing device 50 is actuated to reverse the pushing portion 57 and the hand guide 62 and the tip of the wire 5 are directed to the holding base 10 (see FIG. 14 (e)). Here, the position switching cylinder 31 of the wire guide device is actuated, the holding portion 28 is reversed, the position of the guide die 29 is moved to the left side, and then lowered, and the guide die 29 is positioned to the left side of the magnetic core 2. The drive motor 47 operates to move the pushing device 50 toward the holding table 10. Hereinafter, the above process is repeated to apply the next winding.

The winding to the magnetic core 2 is the winding hole 4 of one half core 2a.
Starting from the upper end of the wire and moving to the lower end in sequence, if the tightening to the magnetic core 2 in the winding process is sufficiently performed and the tension of the wire 5 is controlled to an appropriate value as described above, the pushing position of the wire 5 is Even if it is not changed, the winding positions are sequentially displaced, and the wires are wound in a state where the wires 5 do not overlap and there is no gap therebetween.

After one half core 2a of the magnetic core 2 is wound a predetermined number of times from top to bottom, the other half core 2b is wound from bottom to top. At this time, as shown in FIG. 16, after the tip of the wire 5 pushed from one side is grasped by the pulling device 80, the second wire pressing device 110
Is activated, the arm portion 112 descends from above and presses the wire 5 downward, and in this state, the wire 5 is pulled out by the pulling-out device 80 to wind the crossover wire 5a that transitions between the half cores 2a, 2b. It should be located at the lower end of the hole 4. This prevents the crossover wire 5a from interfering with the newly pushed wire 5 in the subsequent winding process.

[Effects of the Invention] As described in detail above, the invention of the first aspect is provided with a wire pushing device and a wire drawing device on both sides of the magnetic core, and is close to and away from the holding table in the vicinity of the holding table. A rotary member is provided which is free and rotatable in a horizontal plane, and a guide die is attached to the lower portion of the rotary member so as to be eccentric with respect to the center of rotation of the rotary member, and the tip of the wire is guided to the winding term on the guide die. A guide hole having a taper hole is formed, and the eccentric amount of the mounting position of the guide die is adjusted by eccentric rotation of the guide die to the vicinity of one opening and the other opening of the winding hole of the magnetic core. Since the hole is formed in a desired size, the pushing device on one side is advanced to push the wire into the winding hole, and the tip is pulled out by the pulling device on the other side, and then held. Turn the table half a turn Then, the tip of the wire is carried to the pushing device on the other side and this pushing device is moved forward, and when the holding table is pulled out and grasped on one side by the pulling device, the wire is wound once around the half core. By sequentially repeating this, winding is performed by rotating the holding table, so that winding can be performed more quickly than in the case of rotating the arm holding the wire around the holding table as in the conventional case. In addition, the drive mechanism can be small, and the device can be downsized. Furthermore, since the wire can be guided on both sides of the magnetic core by one guide die by eccentrically attaching the guide die to the rotating member, the holding base for holding the magnetic core can be rotated and the guide die can be attached to both sides of the holding base. When using a winding machine configured to wind a wire around the winding hole of the magnetic core using the wire pushing device and the pulling device provided, by rotating the guide die, which side of the winding hole is formed in the magnetic core winding hole. One guide die can be used even when passing the wire through. Therefore, it is not necessary to install guide dies on both sides of the magnetic core holding table.
There is an effect that the device configuration can be simplified as compared with the case where the devices are provided on both sides.

Further, the guide die is eccentrically attached to the rotating member, and the radius of rotation thereof is small because it does not interfere with the magnetic core around the magnetic core, so that the guide die can be moved quickly. Even if the wire winding machine is equipped with wire push-in and wire-out devices on both sides of the holding table to perform quick winding, the movement of the guide die easily follows the winding process and holds it as a result. Winding work can be performed without obstructing the winding speed of the winding machine configured to have the pushing device and the drawing device on both sides of the table.

According to the second aspect of the invention, the holding base is provided with a wire clamp that abuts against the side surface of the magnetic core to prevent the wire from loosening, and the wire clamp can be opened and closed with respect to the magnetic core. By attaching the wire pressing member having, in addition to the effect obtained by the invention of the first claim,
There is no slack in the winding when the wire is replaced, and the above-described process can be smoothly performed.
Further, since the wire is pressed through the flexible wire pressing member, there is an effect that the coating layer of the wire is not damaged and the wire is less likely to be damaged.
