The first and

second rails

510 and 520 are located below the coupling member, and are spaced apart by a predetermined distance so that the first and

second formas

Next, the first forma 400 is provided to receive the wire from the wire supply member 600 and wind the coil, and includes the first moving part 410, the first frame 420 and the first volume. It includes an attachment 430.

The first movable part 410 is provided to be seated on the rail part 300 and move along the first and

second rails

510 and 520, and the first movable part 410 is installed on the rail. In order to move the part 500 in the rail direction, a separate rail is formed to be slidable on the rail and coupled to one side of the first and

second formas

400 and 500, the first and second formas 400, 500) may be provided, but it is natural that various configurations for transferring the first forma 400 may be used.

The first movable part 410 is the rail part (when the winding ends at the first forma 400, the second forma 500 can be disposed at a coupling position formed at the bottom of the coupling member 200). 200) to move along.

The first frame 420 is rotated by the rotation means 100 and is provided to rotate the coil to be wound around the first winding unit 430 .

The first winding unit 430 is provided to wind the wire supplied from the wire supply member 600 while rotating with the rotational power received from the rotation means 100, and a pair of gripping units ( 432, 434).

While the first forma 400 rotates, the first winding unit 430 receives a wire supply from the wire supply unit 600, and coils are spirally wound around the outer periphery of the gripping units 432 and 434. do.

At this time, the wire supply member 600 gradually descends, so that the coil is sequentially wound from the top to the bottom of the outer periphery of the gripping parts 432 and 434 .

The second forma 500 is provided to continuously wind the coil after the coil is wound on the first forma 400, and the second moving part 510, the second frame 520, It includes two winding parts 530.

second formas

400 and 500, but a plurality of formas having the same configuration as the second forma are further provided on one side of the rail unit 300. It will be taken for granted that it can be formed to facilitate multi-pole winding.

Conventionally, in the case of having a plurality of formas, the coil is wound on the forma located on the upper side and then wound on the forma located on the lower side. A phenomenon that is separated from the rotation axis occurs. At this time, the forma located on the lower side is spaced apart from the central axis and rotates while forming a predetermined rotation radius, and the distance from the wire supply device for supplying the wire changes, resulting in a change in tension of the wire. That is, when the forma located on the lower side is separated from the wire supply device, excessive tension is maintained on the wire and the tension rises. do.

Therefore, the second forma 500 moves the rail part 300 and is coupled to the coupling member 200, thereby winding the coil along the rotational axis of the rotating means 100, thereby maintaining a constant wire tension. There is an effect that can be wound while holding.

After that, as shown in FIG. 2-(b), when the operation of the rotating means 100 stops and the coupling member 200 rises, the coupling with the first forma 400 is released.

Next, in FIG. 2-(c), the first forma 400 moves along the rail part 300 by a predetermined distance, and the second forma 500 moves to a position where it is coupled with the coupling member 200. move

At this time, the guide (not shown) is inserted into the rail part 300 to guide the coupling position, and protrudes to the upper surface of the rail when the first and

second formas

400 and 500 move. The second movable part 510 guides the position so that it can be properly positioned in the coupled position with the coupling member 200 .

That is, by providing the guide (not shown), by guiding the coupling position of the first and

second formas

400 and 500, coupling with the coupling member 200 is facilitated, and the forma is positioned at the correct coupling position. It is to improve productivity and prevent the risk of damage by ensuring that it is located.

Next, as shown in FIG. 2-(d) and FIG. 3-(b), when the second forma 500 is disposed in the coupling position, the coupling member 200 descends and the second forma 500 ), receives rotational power from the rotating means 100, and rotates to wind the coil.

In summary, the first and

second formas

400 and 500 are axially rotated according to the rotation axis of the rotating means 100 and the coupling member 200 to wind the coil, and the first and second formas 400 , 500) can be supplied while maintaining a constant tension to the wire supplied from the wire supply member 600 by rotating and winding at the same position, maintaining a distance within a certain range from the wire supply member 600 .

Therefore, as the rotational axis is changed, the tension of the wire is lowered to prevent the coil winding from being twisted or untwisted, thereby providing a high-quality motor and improving productivity and work efficiency.

Although the embodiments of the present invention have been described with reference to the above and accompanying drawings, those skilled in the art to which the present invention pertains can implement the present invention in other specific forms without changing the technical spirit or essential features. You will understand that there is Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
