Reference numeral 1 denotes a coil winding device, and a coil winding jig 1
0, a wire nozzle 75, an alcohol tank 80, and the like. The coil winding jig 10 includes a spacer 11,
It comprises a winding core 20, a winding core 30, a winding width regulating jig 40, a winding width adjusting jig 50, and the like. The spacer 11 has a disk shape, and has a square hole 13 through which the winding core 20 is inserted at the center.
Are formed. A shaft 12 (corresponding to a second locking means) on which the wire is locked is provided upright on the outer peripheral portion 14, and both end faces 16 are formed starting from a diameter larger than the diameter of the core 20. A taper portion 15 for guiding a wire is formed so as to increase the diameter. In the present embodiment, the shaft 12 for locking the wire 85 is provided upright on the outer peripheral portion 14 of the spacer 11. However, the present invention is not limited to this. . The spacer 1
1 by simply adjusting the width t or diameter of the coil A90.
And the coil B95 can be changed. For example,
If the diameter of the spacer 11 is reduced, the interval between the coil A90 and the coil B95 is reduced.

The winding core 20 and the winding core 30 are formed in the shape of a square shaft according to the inner diameter of the coil, and the ends 23 and 32 of the winding core 20 and the winding core 30 are respectively formed in grooves 61 of a spindle 60 of the coil winding machine. Fixed. The winding core 20 is formed with a square shaft portion 21 inserted into the square hole 13 of the spacer 11 and an engagement portion 22 with the groove 31 of the winding core 30. The winding width regulating jig 40 has a cylindrical shape, and is formed with a square hole 41 through which the winding core 20 and the winding core 30 are inserted and a round hole 45 engaging with the spindle 60. Further, a screw hole for fixing the fixing screw 44 to the spindle 60 and a screw 46 for fixing the starting end of the wire 85 at the time of coil winding is formed in the outer peripheral portion.
A taper portion 42 (inclined) for wire guidance is formed on the wire 3 so as to increase the diameter from a diameter larger than the diameter of the winding core 20 as a starting point.

The winding width adjusting jig 50 has a disk shape.
A round hole 52 that engages with the spindle 60 is formed at the center. A screw hole for a fixing screw 51 to the spindle 60 is formed in the outer peripheral portion. Wire nozzle 75
(Corresponding to a moving means) is a guide part of the wire 85 which has a thin cylindrical shape. The wire nozzle 75 is installed in a reciprocating mechanism (not shown) that moves left and right in synchronization with the rotation of the spindle.

The alcohol tank 80 is for winding the wire 85 through the alcohol tank at the time of coil winding to soften the fusion coating on the outer peripheral portion of the wire and to bond and fix the wound wires 85 together. Accordingly, a felt or the like containing alcohol can be used without being limited to the alcohol tank 80. The wire 85 has a structure in which a core wire of a conductor is covered with an insulating film and the outer periphery thereof is covered with a fusion film, and is a self-fusing wire widely used in bobbinless coils and the like. At the time of coil winding, the fusion coating of the wire 85 is moistened with alcohol to soften the fusion coating, and the wound wires 85 are adhered and fixed.

Next, a method of adjusting the jig will be described. To change the winding width of the coil from the W dimension to the V dimension, first, the fixing of the fixing screw 44 of the winding width regulating jig (corresponding to the jig portion) 40 is loosened. Next, the winding width regulating jig 40 is moved in the direction of arrow F, and adjustment is required between the end face 53 of the winding width adjusting jig 50 (corresponding to the stopper portion) and the end face 47 of the winding width regulating jig 40. Insert the gap gauge 70 with the dimensions (WV)
With the gap gauge 70 sandwiched between both end surfaces, the fixing screw 44 of the winding width regulating jig 40 is tightened and fixed. Next, the fixing of the fixing screw 51 of the winding width adjusting jig 50 is loosened, the gap gauge 70 is removed, the winding width adjusting jig 50 is moved in the direction of arrow F, and the end face 53 of the winding width adjusting jig 50 is regulated to the winding width. The fixing screw 51 is tightened and fixed in a state of being in close contact with the end face 47 of the jig 40. When changing the winding width of the coil from the V dimension to the W dimension, the coil width is changed in a procedure reverse to the above procedure. As a result, the width can be easily adjusted without performing special processing on the spindle 60 or the like.

Next, the winding operation of the coil will be described. The wire 85 is passed through the alcohol tank 80, the wire 85 is passed through the wire nozzle 75, and the starting end of the wire 85 is connected to the coil A9.
The wire 85 of the 0-side winding width regulating jig 40 is fixed with the screw 46 for fixing. Next, the winding machine is started and the winding jig 1
When 0 is rotated (spindle is rotated), the wire nozzle 75 reciprocates between the coil widths e to f on the coil A90 side in synchronization with the rotation of the winding jig 10 to wind the specified coil A90. . When the winding on the coil A90 ends, the wire nozzle 75 moves in the direction of arrow K, and moves to the winding start position on the coil B95 side. In this state, the wire 85 becomes oblique at the position between the end of winding on the coil A90 side and the tip of the wire nozzle 75. When further rotated, the shaft 12 erected on the outer peripheral portion 14 of the spacer 11
Rotate with 5 hooked. Then, the wire nozzle 75 reciprocates between the coil widths g and h on the coil B95 side in synchronization with the rotation of the winding jig 10 to wind the specified coil B95. When the winding of the coil B95 is completed, the coil winding machine stops.

Next, the wire 85 is cut, the assembled state of the coil winding jig 10 is released (the spindle moves in a direction to move left and right), and the coil A 90 and the coil B 95 are removed from the core 20 and the core 30 and taken out. Thereafter, the above operation is repeated. The removed coil has the wire end portion 92 of the coil A90 and the wire start end portion 96 of the other coil B95 connected to each other, and the spacer 11 is wound at a desired interval between the coil A90 and the coil B95. . When two continuous coils are used, the wire starting end 91 of the coil A90 and the wire terminating end 97 of the other coil B95 are connected to the connecting parts on the other side, respectively.

As described above, according to the present embodiment, the use of the coil winding jig 10 enables a single-axis spindle winding machine to perform winding with two coils connected at a desired interval. This eliminates the need for connection work between coils by soldering or the like, and reduces the number of soldering steps and eliminates the occurrence of defects in the soldered portion, thereby improving the quality of the coil. Further, since the adjustment of the coil width and the change of the coil interval can be easily performed, the effect can be more exerted in multi-product small-quantity production.

In this embodiment, a rectangular tube-shaped coil having a rectangular inner and outer diameter is wound. However, by changing the shape of the winding core, the coil can be wound into a desired shape such as a cylinder.

[0028]

As described above, winding can be performed with a plurality of coils connected at desired intervals. Therefore, the connection work between the coils by soldering or the like becomes unnecessary, and the number of soldering steps is reduced, and the occurrence of defects in the soldered portion is eliminated, so that the quality of the coil can be improved.
