[0022]
Next, a manufacturing process of the air-core coil will be described with reference to FIG.
A long wire material 10 having an insulating film formed on its surface is supplied and set while being wound on a wire material bobbin 11. The wire material 10 pulled out from the wire material bobbin 11 is guided into the film peeling mechanism 3 by the guide roller 12 under tension while passing through the tension applying mechanism 2.
[0023]
The film peeling mechanism 3 has a plurality of rotary blades 13, which come into contact with the film of the wire material 10, rotate around the central axis of the wire material 10 in the direction of arrow A, and reciprocate in the direction of arrow B. By moving, the film is mechanically peeled to form a film peeling portion 14 having a predetermined length. The length of the wire material 10 from the intermediate point of the film peeling portion 14 to the intermediate point of the next film peeling portion 14 corresponds to the length of the wire material 10 forming one coil.
[0024]
Due to the size of each of the film peeling mechanism 3, the wire feed mechanism 4, and the winding mechanism 5, a wire material corresponding to the length of a plurality of coils between the film peeling mechanism 3 and the winding mechanism 5 10 are stretched, and a plurality of film peeling portions 14 are present between them.
A wire feed mechanism 4 is provided between the film stripping mechanism 3 and the winding mechanism 5, and the wire feed mechanism 4 has a pair of openable and closable grippers 15 a and 15 b for gripping the wire material 10. . The wire material 10 is gripped by the grippers 15a and 15b for the feed mechanism, and the leading end 15 (see FIG. 3) of the wire material 10 is fed to the winding mechanism 5 by a predetermined length. The grippers 15a and 15b for the feed mechanism transfer the wire material 10 by gripping a portion of the wire material 10 where the film peeling portion 14 is not formed, that is, a portion where the film remains.

At the time of winding, as shown in FIG. 3, the front end portion 15 of the wire material 10 is gripped between the winding shaft 17 and the gripper 18 for the winding mechanism, and the feed mechanism grippers 15a and 15b are used to hold a part of the wire material 10 in the middle. To grip. As shown in FIG. 3, the winding shaft 17 and the winding mechanism gripper 18 are rotated together in the direction of arrow C to wind the wire material 10 around the winding shaft 17, and the feed mechanism is synchronized with the movement of the wire material 10. The grippers 15a and 15b are moved to the winding mechanism 5 side.
[0027]
When the wire material 10 is gripped and transported by the grippers 15a and 15b for the feed mechanism, a predetermined tension (tension) is applied to the wire material 10 between the wire feed mechanism 4 and the tension adding mechanism 2, so that the wire material is By rotating the rotary blade 13 in the direction of arrow A with the transfer of the wire 10, the film stripping mechanism 3 is moved toward the winding mechanism 5 by a distance smaller than the moving distance of the wire feed mechanism 4 toward the winding mechanism 5. The film peeling portion 14 can be formed at a predetermined position by a predetermined length.
[0028]
The positions of the feed mechanism grippers 15a and 15b indicated by alternate long and short dash lines in FIG. 3 are the positions at the time when the winding is completed. In this state, the lower blade 20 is moved up and down to cut the wire material 10, and the winding shaft 17 is rotated. The wire material 10 wound above is extracted from the winding shaft 17 to obtain an air-core coil 21 (see FIG. 2). In FIG. 3, an arrow D indicates a reciprocating movement area of the feed mechanism grippers 15a and 15b.
[0029]
The operation sequence at the time of winding is summarized as follows.
(1) Close the grippers 15a and 15b for the feed mechanism,
(2) The feed mechanism grippers 15a and 15b (wire material 10) are fed into the winding mechanism 5 by a predetermined amount,
(3) Close the winding mechanism gripper 18,
(4) The winding shaft 17 and the winding mechanism gripper 18 are rotated to form the air core coil 21, and the feed mechanism grippers 15a and 15b are moved by a length corresponding to one coil, and at the same time,
By rotating the rotary blade 13, a predetermined portion of the wire material 10, a predetermined length of the film is peeled off,
(5) Cutting the air-core coil 21 and the wire material 10 formed by winding,
(6) Open and return the feed mechanism grippers 15a and 15b,
(7) closing the grippers 15a and 15b for the feed mechanism;
Thereafter, by repeating the above operations (1) to (7), coils can be manufactured sequentially.
[0030]
As described above, the film peeling mechanism 3 is driven by the first servomotor (SM1) 6, the wire feed mechanism 4 is driven by the second servomotor (SM2) 7, and the winding mechanism 5 is driven by the third servomotor (SM3) 8. You. These first to third servo motors (SM1) to (SM3) 6 to 8 are controlled by a controller 9.
[0031]
A unit operation amount (a winding amount and a winding speed of the wire material 10) of the third servo motor (SM3) 8 for driving the winding mechanism 5 is detected by the sensor 22 shown in FIG. 1, and based on the detected value. The unit operation amount (the transfer amount and the transfer speed of the wire material 10) of the second servomotor (SM2) 7 for driving the line feed mechanism 4 is initialized. As a result, even when the number of turns of the coil changes, synchronous control can be performed without changing the set value.
[0032]
Alternatively, the external dimensions of the coil can be adjusted by changing the amount of forced transfer of the wire material 10 by the wire feed mechanism 4 to change the amount of wire material wound by the winding shaft 17 having the same diameter. Fine adjustment of the coil inductance is possible by adjusting the external dimensions of the coil.
[0033]
Further, the unit operation amount (winding speed of the wire material 10) of the third servo motor (SM3) 8 for driving the winding mechanism 5 is detected by the sensor 22 shown in FIG. 1, and based on the detected value, the film peeling is performed. The moving amount (peeling length) of the peeling part (rotary blade 13) by the mechanism 3 is controlled. Since the peeling range of the wire material 10 is from the position of the peeling part at the start of the winding to the position of the peeling part at the end of the winding, the operation can be performed by setting these two points.
[0034]
Although not shown, the coil manufacturing apparatus according to the embodiment of the present invention includes a coil mounting mechanism and a mounting position recognizing device, and is configured so that in-line production can be automatically performed in the vicinity of a conveyor through which a work such as a substrate flows. Have been. Each time the produced coil is gripped by the coil mounting mechanism, the mounting position recognition device measures the amount of displacement in the X, Y, and Z directions of the board mounting location on the conveyor, and automatically mounts the coil on the board according to the data. I can do it.
[0035]
In the above embodiment, the case where the air-core coil is manufactured has been described, but the present invention is also applicable to the case of a cored coil.
[0036]
【The invention's effect】
According to the present invention, it is possible to prevent the peeling position from being shifted due to a slight elongation of the wire material or the entrapment of dust at the time of winding, and to forcibly feed the wire so that the peeling position always comes to a predetermined position of the coil. It has the effect of producing and eradicating defective products.
[0037]
In addition, since the winding and the peeling are operated in parallel, there is an effect that the non-operation time of each mechanical unit is reduced and the coil manufacturing time is shortened.
[0038]
Furthermore, by adjusting the amount of wire feed forcibly, the winding amount of the wire with the same diameter of the winding shaft is changed, and the outer shape of the coil is varied, enabling fine adjustment of the electrical characteristics of the coil. I do.
