Description

[Detailed description of the invention] This invention relates to an automatic winding machine, and more specifically, a flyer-type automatic winding machine has a lead wire end processing function that mechanically winds the lead portion of a coil terminal around the coil terminal. This relates to the added automatic winding machine.

Conventionally, as in the case of intermediate frequency transformers, most of the process of winding wire around a bobbin using a machine to form a coil and then wrapping the terminal lead portion around the coil terminal was 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 a plurality of tools such as a bin vise and special pliers in the case of a large bottom. Along with the automatic winding of wire rods onto bobbins, attempts have been made to mechanize the process of winding the lead portion onto coil terminals, but in order to deal with the size and thickness of wire rods for transformers, it has been difficult to 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 material around the thin and short coil terminal, so it was not expected to be more efficient than manual work. However, it has not yet been put into practical use.

Furthermore, even if it is mechanized, these processes are separated from winding the wire onto the bobbin, winding the lead part onto the coil terminal, and cutting the remaining part of the wound lead wire. During this time, human intervention had to be made.

This invention aims to eliminate the above-mentioned drawbacks, and its feature is that the amount of rotation in the forward and reverse directions of the servo motor, which is program-controlled by the operating mechanism, is converted into reciprocating momentum to attach the fryer. The flyer mechanism is fixed to the bobbin mounting portion by a transmission mechanism that moves the flyer mechanism forward and backward, and simultaneously rotates one or more flyers of the flyer mechanism in a clockwise or counterclockwise direction using a servo motor that is similarly program-controlled. To provide an automatic wire winding machine having a function of attaching a lead wire to a coil terminal by rotating the wire around a coil terminal protruding in the radial direction and a coil terminal. It is something. An embodiment of this invention shown in the drawings will be described in detail below.

The bobbin attachment part 3 is shown in FIGS. 1 to 3 and 9.
As shown in the figure, there is a line on the outer periphery of the cylindrical member 31 that divides the circumferential surface of the member into a plurality of parts, and a line that corresponds to the axial center position of the fryer mounting shafts 14a to 14d of the fryer mechanism part 1 in the longitudinal direction. At the intersecting position, a flange 32 is attached to which a mounting rod 33 having a screw 331 at one end and a slot 332 for mounting a bobbin mounting jig 34 at the other end can be screwed, as shown in FIG. 9. It is designed so that it can be rotated by a constant angle by an operating mechanism section 5.

The operating mechanism section 5 is composed of the above-mentioned flyer rotation servo motor 26, feed servo motor 27, and a control mechanism section that controls the bobbin mounting section 5 in a program.

The flyer type automatic winding machine of this invention is constructed as described above, and the operation of winding the wire around the bobbin and winding it around the coil terminal using this winding machine will be explained below.

First, as shown in FIGS. 2 and 3, the mounting rod 33 is screwed onto each flange 32, and a slot 332 at the tip of the mounting rod is inserted into the slot 332 selected according to the shape of the bobbin 6 as shown in FIG. Attach a mounting jig 34 with the inserted mounting screws 35, and fit the bobbin into this jig.

Next, as shown in FIGS. 1 to 3 and FIGS. 5a and 5b, the wire a is attached to the guide roller 215a, the shaft hole of the flyer mounting shaft 14a, and the flyer 17 from the bobbin 7 wound with the wire a. It passes through the guide rollers 18 and pipe guides 19. The same procedure is applied to the remaining three same constituent parts. Furthermore, the operator ties the ends of the four wire rods a1 to a4 to the mounting screws 35 of the mounting rod 33.

With the above preparations complete, the operator operates the start button on the operating mechanism section 5.

Then, the fryer rotation servo motor 26
As shown in Figures 0a and 0b, the flyer 17 is rotated slightly counterclockwise to slightly tilt the flyer 17 toward you, and the feed servo motor 27 rotates forward to rotate the flyer mechanism 1 through the mechanism described above. The pipe guide 19 is guided slightly backward to the opposite side of the coil terminal 61 protruding in the radial direction of the bobbin 6. That is, the tip of the pipe guide 19 moves from point P11 to point P12 in FIG. 12.

Next, the fryer rotation servo motor 26 rotates clockwise slightly more than the above rotation amount, and the first
By tilting the pipe guide 19 to the opposite side as shown in Fig. 0c, the position from point P12 in Fig. 12
The tip of the pipe guide 19 moves to point P13.
Next, the feed servo motor 27 is reversed to advance the flyer mechanism 1 by a slight amount via the above-mentioned mechanism, and the tip of the pipe guide 19 is moved in the direction shown in FIG.
As shown in Figure 2, advance from point P13 to point P14. Next, the flyer rotation servo motor 26 rotates a little counterclockwise again to move the tip of the pipe guide 19 from point P14 to point P11 shown in FIG. 10e [same position as FIG. 10a] and FIG. 12. By moving the wire rod a, the wire rod a is twisted around the coil terminal 61 once. Thereafter, this operation is repeated several times to finish tying the wire a to the coil terminal 61 a predetermined number of times.

When this initial winding operation is completed, the feed servo motor 27 rotates normally again, and the flyer mechanism section 1 is moved back through the above-described mechanism to move the pipe guide 1
When the tip of the flyer 9 has been moved from point P11 to point P12 as shown in FIG. 10 f and FIG. The flyer mechanism section 1 is rotated forward and reverse by an effective winding width of 6 to give a traverse motion to wind the wire rod a around the bobbin 6 the required number of times.

When this winding operation is completed, as shown in FIGS. 11a-e and 12, the flyer rotation servo motor 26 and the feed servo motor 27 are connected to the coil terminal 62 side of the bobbin 6 in the same way as in the case of the coil terminal 61 described above. By controlling the program, the tip of the pipe guide 19 of the flyer 17 is adjusted to P21 in Figure 12.
Rotate from point to point P24 and perform the twisting operation at the end of the coil winding.

When the end of this winding operation is completed, 4
After the winding of the wire rod onto each bobbin is completed, the bobbin attaching part 3 is fixed at an angle θ as shown in FIG.
(10°) clockwise and move to the next bobbin 6.
a to 6d are the four fryers 1 of the fryer mechanism section 1
7a to 17d, and in this case, the difference from the previous case is that the starting ends of the wires a1 to a4 to be tied to the coil terminals of the next bobbin are tied to the coil terminals 62 that were tied in the previous operation. Hereinafter, by the same operation as described above, the coil terminal is tied and the bobbin is wound in the same manner, and the above-mentioned operation is applied to the fryer while the bobbin mounting portion 3 is rotated by the angle θ six times, that is, once. Therefore, in the case of the embodiment, winding of the terminal strips onto the 24 (6 x 4) bobbins is completed, and then the connecting wires are cut and the bobbins are removed from the mounting jig 34. good.

During the above-mentioned tying operation to the coil terminal, the bobbin attachment part 3 is lowered by a slight amount in accordance with the rotation speed of the pipe guide 17, and when the tying operation is completed, it is raised again by the above amount, so that the tying will be in the same position. There is no risk of the pipe guide 17 interfering with the crossover wire because it does not get tangled several times.

As mentioned above, this invention converts the amount of rotation in the forward and reverse directions of the servo motor, which is program-controlled by the operating mechanism, into reciprocating momentum, and moves the flyer mechanism, to which the fryer is attached, forward and backward. A transmission mechanism that simultaneously rotates one or more flyers of the flyer mechanism in a clockwise or counterclockwise direction by a servo motor is used to attach wire rods around the bobbin fixed to the bobbin mounting section and the coil terminal protruding in the radial direction. Since the wire is rotated to perform the winding and winding, the winding of the wire to the coil terminal of the bobbin can be done in the same way as the winding of the wire to the bobbin, resulting in a marked improvement in work efficiency and two Since the rotation of the fryer and the amount of movement in the axial direction are controlled by two shafts connected to a servo motor according to a program set in advance in the operating mechanism, the mechanism is simple.
