Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a lead to a coil terminal in an automatic winding machine. The present invention relates to a method for winding coil terminals in an automatic winding machine equipped with a lead wire end processing function for winding coil terminals.

Conventionally, as in the case of intermediate frequency transformers, wire rods are wound around a bobbin using a machine to form a coil, and most of the process of winding the terminal lead part of the coil terminal C is done manually. Regardless of the size of the intermediate frequency transformer, if the intermediate frequency transformer has a large bottom, a plurality of tools such as a bin vise and special pliers are used to attach and cut the lead portion to the coil terminal. Attempts have been made to mechanize the process of winding the lead part onto the coil terminal due to the automatic winding of the wire to the bobbin of M material, but in order to cope with the size of the transformer wire and the thickness of the wire, many types of intermediate frequency Winding the transformer leads around the coil terminals requires a complicated machine structure, and in particular, it was not possible to create a mechanism sufficient to wind the thin wire around the thin and short coil terminals, so it took more than manual work. It has not been put into practical use as the efficiency cannot be expected.

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 lead wire.・The purpose of this invention is to eliminate the above-mentioned drawbacks, and its features are that the flyer is rotated by a servo motor for rotating the flyer, and the winding a second transmission mechanism for moving the first servo motor in the direction toward and away from the bobbin to be installed, and for transmitting power interposed between the flyer and the flyer rotation servo motor; In an automatic wire winding machine that moves up and down with a servo motor, the flyer's pipe guide is moved from one side above the coil terminal of the bobbin to the other by rotating the flyer ear by a certain angle from one side to the other using the servo motor for rotating the flyer. Then, lower the second servo motor (second transmission mechanism part), and then move the rainbow pipe guide to the fryer rotation servo motor in the opposite direction C; below the coil terminal. After the wire is moved in an arc toward the wire side, the second servo motor raises the wire transmission mechanism, and the above operation is repeated a predetermined number of times to attach the wire to the coil terminal. It is an object of the present invention to provide a method for attaching coil terminals in an automatic winding machine.Hereinafter, an embodiment of the present invention shown in the drawings will be described in detail.

This alternating flyer type automatic winding machine is constructed as described above, and the operation of winding the wire and winding it around the coil terminal will be described below.

First, the mounting rod 33 is screwed onto each of the seven flange 32 as shown in FIG. 2 and FIG. 34 with the insertion mounting screw 35, and the bobbin is fitted into this jig.

Next, Figures 1 to 3 and Figures 5 (α) and (b)
As shown in FIG.
The guide roller 18 attached to the layer 17 passes through the vibrator guide 19. The same procedure is applied to the remaining 93 same constituent parts. Furthermore, the handler handles four wires α1 to α
4 is attached to the mounting screw 35 of the mounting rod 33.

In addition, in this case, a plurality of coil terminals 61 of the bobbin 6 attached to the bobbin attaching portion 3 are connected to each other as shown in FIG. 10(α).
〜64, diagonally upper left position P of the coil terminal 61,
The tips of the vibrator guides 19 of the flyers 17α to 17d are positioned in advance. When the preparation is completed as described below and the operator operates the start button of the operating mechanism section 5, the left and right feed servo motor rotates forward according to the numerical value of the operating mechanism section 5 or the program control procedure, and the fryer installation of the fryer mechanism section 1 is performed. Move the axes 14α to 14d to the left by a dimension of 11 and move 7.
The pipe guide 19 attached to the 2-ear is dimension 18.
to the right and bring the pipe guide 19 to position P1 as shown in FIG. 10 (6). Next, the flyer rotation servo motor 26 is rotated in the forward direction so that the pipe guide 19, which is in position P, passes above the coil terminal 61 which protrudes in the axial direction from the end surface of the bobbin 6 on which the wire is to be tied. Position P! Move up to Next, the second feed 9 servo motor 46 rotates forward and the frame members 4 and 2 are vertically lowered by a certain distance. is lowered, and the pipe guide 19, which was in position P, moves to the positions P and t shown in FIG. When the pipe guide 19 is rotated by the dimension ℃, it is in the reverse C position P (the two pipe guides 19 pass through the lower side of the coil terminal 61 and the
It moves to position P4 as shown in Figure 0+d).

Finally, the second feed servo motor 46 is reversed and #4y#42 is raised vertically by a certain amount, contrary to the above, and the pipe guide 19 that was in the bondion P4 is moved as shown in FIG. 10(e). Return to position P1. In this way, the tip of the pipe guide 19 is moved so as to draw a substantially rectangular locus, and the pipe guide 19 is moved to position P as described above.
to Pl, and winding of the wire α around the coil terminal 61 once to a position close to the flange surface of the bobbin 6 is completed. Therefore, as shown in FIG. 10(e) (: while the pipe guide 19 is returning from position P4 to Pl, the control procedure of the operating mechanism section 5 is linked to the forward rotation of the second feed υ servo motor 46. After rotating the first feed servo motor 27 and retracting the flyer mechanism section 1 toward the transmission mechanism section 2 by the diameter of the wire α, the above-mentioned twisting operation is performed, and then the above-mentioned operation according to the control procedure is performed. Do both movements several times (;
The wire α can be attached to the coil terminal 61.

After this work, make sure that the center 0 of the rotation trajectory of the pipe guide 19 is at the center of the bobbin 6 as shown by the chain line in Fig. 10 (α).
．． 47 to change the position of the pipe guide 19 of the fryer 17, the length C of the bobbin 6 is approximately equal to the length C of the flyer mechanism part l by forward rotation of the flyer rotation servo motor 26 and forward and reverse rotation of the first feed servo motor 27. The coil is reciprocated to complete the primary coil by winding it the required number of times while causing the flyer to move in a traversing motion, similar to the winding machine used in the past.

When the second wire material a of the bobbin 6J has been wound a required number of times, the end of the coil is then tied to the coil terminal 62 in the same manner as described above.

Note that the servo motor 47 for the left and right feed ga is not necessarily required, and can be substituted by controlling the rotation angle of the bobbin attachment part 3, and as described above, the rotation of the bobbin attachment part 3 and each servo motor can be used as a substitute. The pipe guide 19 can be positioned with respect to each coil terminal of the bobbin 6.

When this winding end winding operation is completed, winding and winding of the wire material α as a partial coil onto four bobbins at once is completed, and the secondary coil is also wound in the same way. to attach.

Next, the bobbin mounting part 3 is set at the θ angle (60
Q) in the clockwise direction so that the next bobbins 6a to 6d face the four flyers 17α to 17d of the flyer mechanism 1. In this case, the difference from the previous case is that the next bobbin coil of the wires α1 to α4 Since the starting end of the terminal is tied to the coil terminal 64 of the previous four bobbins in the previous operation, the same operation as described above can be performed, and the bobbin attachment part 3 is moved by the angle θ 6 If the bobbin mounting part 3 is rotated, in other words, if the bobbin mounting part 3 is rotated once, the operation command can be issued to the fryer, fryer mechanism part, transmission mechanism part, and bobbin mounting part according to the operating procedure. Therefore, in the case of the embodiment, winding of coils on 24 (6×4) bobbins and winding operations on coil terminals can be performed.

When the coil terminal 64 of the bobbin 6 is attached to the coil terminal 64 of the bobbin 6 by the above-described operation, a wire is generated when the bobbin mounting portion 3 is rotated by 60 degrees.
flanges 3 protruding at equidistant positions in the circumferential direction of 1;
As shown in Fig. 11, a C2 clamping tool 35 is provided in the middle of the bobbin mounting section 31; Cut this crossing p-wire from the coil terminal end.

FIG. 9 (6) shows the relationship between the flyer 17 and the pipe guide 19 for a bobbin whose coil terminal protrudes in the radial direction. This is approximately the same as the case described above.

The pipe guide of the flyer is rotated around the bobbin, and the pipe guide is moved around the coil terminal on a circular locus and on a vertical straight locus to wind it. The wire rods can be attached to the coils and terminals of the bobbin in the same way as winding them to the bobbin, and can be done using the same mechanism without having to remove them, which significantly improves work efficiency. , the flyer for winding the bobbin body can be rotated by reciprocating at a fixed angle, and the coil terminal can be attached to the coil terminal, making it easy and simple to control. It is also possible to reduce the number of parts.
