7 engages with the notch 106 of the winding core 31, and the winding core 31 is pushed down as a result. As a result, the winding core 61 is detached from the coil 105, and after the stator holder 100 is lowered and appropriately pressurized onto the n1 coil, it is heated by the electrode 54 constituting the fusing means 91. The coil group and the stator yoke 1 are configured to be fused together.

Note that on one side of the stator yoke holder 100,
A sliding push 102 and a support pin 104 are attached.

In the multi-pole flat coil manufacturing device that requires 1 force in the configuration described above,
As shown in FIG. 7, first, the table 11 is moved via the reciprocating means 24t of the table 21 to the coil forming position AVC and the winding form holder 33i having the empty winding form 29 thereon.

Then, as shown in FIGS. 6 and 8, the rotation, position, and positioning means 38 of the winding form holder 33
# in the winding form held in! The winding form 29 of the '1st pole is positioned at the winding position C.

When the winding form 29 of the first pole is positioned, the sixth pole
As shown in the figure, the means 47VC for pushing up the winding form 29
The winding form 29 is pushed up, and the winding core 3'1 of the winding form 29 passes through all the holes 90 formed in the coil presser 89 and is raised to a position higher than the upper surface of the coil presser 89.
1 is brought into contact with the fryer side 7 flange 87 of the coil forming portion 84 of the fryer unit red 55 with appropriate pressure and force so as to be in "g" contact.

As shown in FIGS. 6 and 10, the wire 104 is guided to the flyer 70 through the inside of the flyer shaft 59 of the flyer unit 55, and one end of the V-shaped wire 104 is hooked onto the clamper 53. I can't stop it. This wire 104 has a self-melting skin when heated.

Next, as shown in FIG. A6, FIG. 9, and FIG.
Rotation operated through rotation with 9 and movement block 7
The pulse motor 80, the traverse cam 82, the cam follower 83, and the moving block 78, which constitute the drive unit 8, work together to traverse the wire 104 vertically by one pitch equal to the diameter of the wire 104 per rotation. As the flyer 70 is rotated and traversed, the wire 104 is wound around the winding core 31 between the winding flange 6o of the winding former 29 of the first pole and the flyer side flange 87. By repeating the winding, nr=m is set by the flyer side flange 87,
A coil 105 having a height set to r is formed by the winding flange 3o and the flyer side flange 87.

When the coil 105 is formed on the 100 millionth winding form 29, the pushing up means 47 of the winding form 29 is returned, and the coil 105 is
11 at which the winding form 29 having the shape can enter the coil presser 89.
Then, the rotational positioning means 38 of the winding form holder 35 is rotated by one pitch to move the winding form 29 of the second pole n1.
At the same time as the coil 105t is sent to the winding position C, the winding form 29 having the coil 105t formed at the first pole is moved under the coil presser 89 and is pressed so that the coil 105 does not collapse.

After the second pole winding form 29 is set at the winding position C, the coil 105 is formed in the same sequence as the coil 105 was formed on the first pole winding form 29, and this operation is repeated. Therefore, in this embodiment, up to the eighth pole coil 105 is formed, and the end of the winding wire is held by the clamper.

In addition, in the normal case, the above-mentioned winding is the coil 10 of the m1 pole.
5 is clockwise, the coil 105 of the second pole is wound counterclockwise, and so on, alternately in opposite directions.

When the coil 105 is formed on all the winding forms 29 □
.

Then, electricity is applied to the coil group through the electrode 54 constituting a means for fusing the coils together, and the winding start line end and winding end line end of the coil group, and the adjacent coils are fused together by Joule heat.

After the coils are fused together, the reciprocating means 24 for the table 21
Accordingly, the table 21 is moved to transfer the coil group to the welding position BVc between the coil group and the stator yoke 1.

When the coil group moves to the fusion position B and stops,
The stay yoke 1, which is clamped in advance on the stator yoke holder 100 of the means 91 for fusing the coil group and the stator yoke 1, is turned over as the rotating cylinder 98, rotating shaft 99, and stator yoke holder 100 rotate. Cylinder 92, piston rod 93, L-shaped bracket 94,
By lowering the stator yoke holder 100, the stator yoke 1 is placed on the coil group.

This lowering operation of the stator yoke holder 100 engages the stator positioning pin 101 provided on the stator yoke holder 100 with the adjustment screw 108 .

At the same time, push down the guide member 37 and remove this guide part.
Due to the lowering action tIjJ of the second member 37, the protruding member 107 of the guide member 37 engages with the notch 106 of the winding core 51, and as a result, the winding core 31 is pushed down, and when the stator yoke is placed on the coil group, the winding Core 31 is removed from coil 105.

The coils that have been appropriately pressurized in this way are energized again through the electrode 54t in this pressurized state, and
The stator yoke 1 and the coil group formed of the wire material 104 having self-fusion properties are fused. After this fusion, the cylinder 92 for raising and lowering the stator yoke holder 100 is operated to raise the stator yoke holder 100, which has the stator yoke 1 and the coil group fused thereto, and then the stator yoke holder 100 is lifted. The rotary cylinder 98 of the holder 100 is rotated, the stator yoke holder 100 is reversed, and a multipolar flat coil is manufactured.

Note that when the coil group and the stator yoke 1 are fused together, in order to increase the adhesive strength between the two, a heat adhesion film may be laid over the coil group, and the stator yoke 1 may be fused.

Further, in this embodiment, although the electrode 54 is used as the means for fusing the coils and the coil group and the stator yoke 1, the present invention is not limited to this, and hot air may also be used. Furthermore, the specific structure of each part is not limited to that of the illustrated embodiment.
Any structure that can fulfill the intended function may be used.

The present invention has the configuration and operation described above, and according to the present invention, it is possible to form a coil by automatically winding it on a winding form for the required number of poles, and it is not necessary to connect the coils 4 of adjacent coils. It is possible to automatically fuse adjacent coils and the coil group to the stator yoke.Furthermore, since the winding core is removed from the coil when the coil group and stator yoke are fused, the coil Since there is no need to build up a layer on the winding core, it is possible to automatically manufacture multi-pole flat coils with fewer defective products with less man-hours.
