The present invention relates to an automatic wire winding machine that is equipped with a lead wire terminal processing function.

[Prior art] Conventionally, after winding a wire around a bobbin of an intermediate frequency transformer to form a coil, the process of winding the terminal lead portion around the coil terminal has been mostly done manually. Regardless of the size of the intermediate frequency transformer, the process involves attaching and cutting the lead portion to the coil terminal using multiple tools such as a bin vise and special pliers. Attempts have been made to mechanize the process of winding the lead portion onto the coil terminals in conjunction with automatic winding machines for wire rods onto bobbins. In order to wrap the lead part around the coil terminal, the structure of the machine was complicated, and in particular, it was not possible to obtain a mechanism sufficient to wrap the thin wire around the short coil terminal.
It has not been put into practical use because it cannot be expected to be more efficient than manual labor.

[Problems to be solved by the invention] Even if these processes are mechanized, it is difficult to wind the wire around the bobbin, wind the lead part around the coil terminal, and cut the remaining part of the wound lead wire. Each item was processed separately, and manual intervention was required in between.

The processing operation will be explained.

First, as shown in FIG.
The bobbin 35 is attached to the 24 bobbin attachment jigs 33. Next, preparation is completed by passing the wire a from the drum 7 wound with the wire a through the guide roller 215a, the shaft hole of the flyer mounting shaft 12, and the pipe guide 131 attached to the flyer 13. When the start button of the control unit 5 is operated, the servo motor 14 for rotating the fryer is activated as shown in FIG.

The wire material a is moved in a rectangular shape with two sides arcuate and the other two sides linear, and the tip is fixed to the bobbin mounting jig 33 etc., and the wire rod a is attached to the coil terminal 36.

Next, the guide pipe 131 of the flyer 13 is rotated around the bobbin 35, and the wire rod a is wound around the bobbin the required number of times. When this winding operation is completed, the wire rod is attached to the other coil terminal 36 by one of the operations described above again. to provoke.

In this way, the vertical 4
The wire rod A is wound onto each bobbin with exactly the same specifications using four flyers at the same time, and when the winding to the coil terminal is completed, the connecting wire processing section 4 performs processing while the bobbin mounting section 34 rotates 60 degrees. The mechanism section 91 is moved forward by the pair of operating mechanisms 22 and 23, and the wire processing arm 314, which has a forked tip, separates the crossover wire a from the winding of the wire as shown in FIG. 6a. The second coil terminal of the bobbin 35 and the guide pipe 131 of the flyer are reinforced in the fork, and the guide pipe 131 is rotated around the rear side of the coil terminal 36 of the bobbin 35 from the position A shown by the broken line. When the servo motor is rotated in accordance with the control command from the control unit 5, the processing mechanism unit rotates the servo motor in accordance with the control command from the control unit 5, and the gear 3
23, 333 and the support rods 325, 335 move, the wire processing arm 314 descends from the position shown by the broken line to the position shown by the solid line, and moves from the position shown by the coil terminal to the coil terminal position of the next bobbin. Lower the crossover wire that has been brought up to the end of the coil terminal 36 to the bobbin 35, then wrap it around the coil terminal several times using one of the above-mentioned twisting operations, and then wrap it around the bobbin 35 the required number of times. , coil terminal 3 again

Next, as shown in FIGS. 6b and 6c, when the winding of the coil terminal 36 of the bobbin 35 is completed in the same manner as described above, the wire processing arm 31 which is redirecting the crossover wire a
4 is rotated by 90 degrees to 170 degrees by a servo motor 315 to cut the crossover wire a at the end of the coil terminal.
In this operation, since the diameter of the wire a is very small, the coil terminal 36 does not bend during this cutting.

[Effects of the invention] As described above, this invention mounts a plurality of flyers that are mounted on the shaft support frame 11, connected to the servo motor 14 via the transmission shaft 24 of the transmission mechanism section 10, and rotated in a predetermined direction.

It is composed of a control mechanism 3 that programmatically controls the
The amount of rotation in the forward and reverse directions of each servo motor, which is program-controlled by the control unit 5, is converted into reciprocating momentum, respectively, to move the flyer 13 forward and backward, and the servo motors, which are also program-controlled, convert one of the flyers 13 into reciprocating momentum. The wire material a is rotated clockwise or counterclockwise at the same time, and the wire material a is rotated around the bobbin 35 fixed to the bobbin mounting portion 34 and the coil terminal 36 protruding from the bobbin 35. Since it is possible to wind the wire and cut the completed wire from the coil terminal 36, winding the wire to the coil terminal of the bobbin can be done in the same way as winding it to the bobbin, and each part can be operated. Since it is controlled by a program set in advance in the control unit, the mechanism is simple, and it is easy to connect coil terminals to a large number of bobbins arranged in the radial direction of the bobbin mounting part, and to wind the coil terminals around the bobbins. Since the processing of the crossover wire portion is carried out continuously and automatically, it has the effect of significantly improving work efficiency.
