Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for automatically manufacturing a closed loop work, especially a short ring for a rotary transformer.

[0002]

2. Description of the Related Art A rotary transformer is widely used as a means for transferring a signal between a rotary magnetic head of a rotary magnetic head device applied to a video tape recorder, a digital audio tape recorder, etc. and a recording / reproducing amplifier. It is used. FIG. 15 is a schematic diagram showing an application example of a rotary transformer to a rotary magnetic head device. In FIG. 15, reference numeral 300 is a stator, and the rotor 301 is rotatably assembled to the stator 300. The rotor 301 has a head chip 302, and is rotated about an axis L by driving a motor (not shown). The rotary transformer is composed of a core 310 on which coils 311 and 312 are mounted and a core 313 on which coils 314 and 315 are mounted. Such a core 310 is attached to the stator 300, and its coils 311 and 312 are guided to an external circuit. On the other hand, the core 313 is attached to the rotor 301 so as to face the core 310, and its coils 314 and 315 are electrically connected to the head chip 302. As a result, the coils 311 and 314, 312 and 3
Reference numeral 15 is magnetically coupled so that signals are transmitted between the head chip 302 and an external circuit. In such a rotary transformer, as shown in the figure, the short ring usually consists of a closed loop of one turn, and the short rings 320 and 321 are the cores 310 and 31.
The third short ring grooves 310a and 313a are inserted into the short ring grooves 310a and 313a to block the magnetic coupling between the coils 311 and 312, 314 and 315, and to prevent noise generation.

Conventionally, the manufacturing of the short rings 320 and 321 of the rotary transformer and the insertion work into the cores 310 and 313 have been performed as follows. That is, after the short rings 320 and 321 are manufactured through a wire winding process and the like, the manufactured short rings 320 and 321 are manufactured.
Stock once. Then, the stocked short rings 320, 321 are manually conveyed to the next insertion step, and in the insertion step, the short rings 320, 321 are
321 cores 310, 313 manually with a fixed setup.
The insertion work of pushing into the short ring grooves 310a and 313a was performed.

[0004]

However, the following problems have been encountered in the manufacture of the conventional short ring described above. That is, the manufactured short rings 320, 321
After stocking once, the process is moved to the inserting process, so that the short ring manufacturing work and the inserting work are separate processes, and it takes a long time to assemble the rotary transformer. In addition, in the insertion process, the short ring 320,
Since the work of inserting the 321 by pushing the 321 into the short ring grooves 310a and 313a is performed, the short rings 320 and 321 are deformed or the short rings 320 and 321 are not sufficiently pushed into the short ring grooves 310a and 313a. There was a situation that it was not installed on the machine, and there was a quality problem.

Further, in the conventional welding of the winding joint portion of the short ring of the rotary transformer, there is a problem that the amplitude of the tip of the welder changes and the finished state is not constant. Further, since the conventional cutting of the wire rod after welding uses a push-cut type cutter, the portion remaining from the joint tends to be long, the wire rod is crushed, or the cut surface shape is not constant,
There was a problem that the upper wire and the lower wire could not be cut at the same time. In particular, if the remaining portion of the wire rod that cannot be completely cut from the joint portion is long, the electrical characteristics when assembled in a rotary transformer are adversely affected, and it becomes difficult to insert the core into the groove in a later step.

An object of the present invention is to solve the above problems by providing a winding device capable of automatically producing a closed loop work, especially a short ring for a rotary transformer.

The wire rod joining portion 100b of the wire rod 100 can be welded by sandwiching it with 0a and applying pressure, and then applying torsional vibration to the horn 23. In this way, the horn 23 is caused to generate not the linear vibration but the torsional vibration, so that the vibration transmission force is stabilized and the efficiency is improved.

Further, as shown in FIG. 7, tooth-shaped unevenness 24a is formed on the horn tip portion 24 of such a welder 21. Further, tooth-shaped irregularities 10a1 are also formed on the outer surface of the anvil 10a with which the wire-bonding portion 100b contacts. Thereby, the wire rod joining portion 100b of the winding body sandwiched between the horn tip portion 24 and the anvil 10a.

In FIG. 12, reference numeral 202 is a core jig for mounting the core 201, which is vertically moved by an actuator 203. Further, reference numerals 50 and 51 are laser sensors attached to a fixed portion (not shown). These laser sensors 50 and 51 detect the presence or absence of a short ring of the mold 10 and send the detection signal to the control device 5. It is a sensor that sends out.

In FIG. 1, the control device 5 is a device for operating the above-mentioned mechanisms in a fixed procedure. Specifically, as will be described later, each mechanism is operated in the order of winding process A to conveyance and insertion process D, and the conveyance and conveyance of the core 201 to the insertion position I by the conveyor 200 and the insertion mechanism 4 are performed.

When the short ring 100e is in the mold 10, the core 201 on the conveyor 200 is lifted up integrally with the core jig 202 by the actuator 203, and as shown by the chain double-dashed line in FIG. Is positioned directly below the mold 10, and the subsequent insertion work is performed.

That is, as shown in FIG.
The actuator 44 drives the pusher 43 with the center pin 10b inserted in the center hole of the core 201. As a result, as shown in FIG. 13B, the arm 10g of the ejector 10c is pushed down by the pusher 43, and the ring press portion 10e is pushed out downward.

As described above, according to the winding device of this embodiment, after the short ring 100e is manufactured by the winding mechanism 1, the welding mechanism 2 and the cutting mechanism 3, the short ring 10e is formed.
Since the short ring 100e can be continuously conveyed and inserted by the conveying / inserting mechanism 4 without stocking 0e, the rotary transformer can be assembled in a short time, and as a result, the productivity can be improved. It is possible to improve. Further, the short ring 100e is automatically produced by the winding mechanism 1, the welding mechanism 2, and the cutting mechanism 3, and the produced short ring 100e is automatically produced by the transporting and inserting mechanism 4 in the short ring groove 2 of the core 201.
