The first coil winding unit 100 forms the first coil part 12 on the winding axis 120 and the second coil winding unit 200 forms the first coil winding part 120 on the winding axis 120. In this embodiment, In order to wind the first coil part 12 to be wound on the winding shaft 120 and the second coil part 14 to be wound on the winding shaft 120 with the same winding, The rotation speed of the rotation shaft 212 of the two-coil winding unit 200 is rotated twice faster than the rotation speed of the winding shaft 120 of the first coil winding unit 100. [

On the other hand, in order to wind the first coil part 12 wound on the winding shaft 120 and the second coil part 14 wound on the winding shaft 120 with different winding windings, the second coil winding unit 200, The rotational speed of the rotating shaft 212 of the first coil winding unit 100 is rotated at a rotational speed faster than the rotational speed of the winding shaft 120 of the first coil winding unit 100,

The tension control unit 400 provides a pulling force to the wire 1 clamped to the wire clamp 330 to apply a constant tension to the wire 1. [

When a tension is applied to the wire 1 clamped to the wire clamp 330, the large surface of the wire 1 is brought into close contact with the winding shaft 120 and the wire 1 is brought into close contact with the winding shaft 120 The electric wire 1 is wound on the winding shaft 120 by the winding shaft 120 being rotated so that the first coil portion 12 of the two-stage coil 10 shown in Fig. 3 is formed.

If no tension is applied to the wire 1 clamped to the wire clamp 330, it may not be in close contact with the surface of the wire 1 and the winding shaft 120. If the electric wire 1 is not in close contact with the winding shaft 120, the electric wire 1 is not wound on the winding shaft 120 even if the winding shaft 120 is rotated.

On the other hand, when a tension suitable to the type and specification of the electric wire 1 clamped to the electric wire clamp 330 is not applied to the electric wire 1, the electric wire 1 is cut off due to the tension or the electric wire 1 is not correctly wound have.

The tension control unit 500 continues to provide the traction force to the wire clamp 330 even when the transport unit 320 transports the transport block 310 and the wire clamp 330 so that the transport unit 320 can move The wire 1 clamped to the wire clamp 330 is wound on the winding shaft 120 so that the wire 1 clamped to the wire clamp 330 can be uniformly tensioned It is possible to prevent the occurrence of winding defects of the first coil part 12 during the formation of the one coil part 12.

When the winding shaft 120 is rotated so that the first coil portion 12 which is a part of the two-stage coil 10 is formed on the surface of the winding shaft 120, The rotation shaft 212 of the coil winding unit 200 is rotated at a second rotation speed that is faster than the first rotation speed of the winding shaft 120 simultaneously with the rotation of the winding shaft 120, The electric wire 1 provided from the bobbin 610 is wound on the upper portion of the first coil portion 12 of the winding shaft 120 to form the second coil portion 14. (Step S30)

At this time, the winding shaft 120 is rotated at a first rotational speed along the clockwise direction, and the rotational axis 212 of the second coil winding unit 200 is rotated clockwise by twice the first rotational speed of the winding shaft 120 The first coil portion 12 and the second coil portion 14 are wound in the same winding direction.

On the other hand, when the winding shaft 120 is rotated at the first rotation speed and the rotation axis 212 of the second coil winding unit 200 is rotating faster than the first rotation speed and slower than twice, When rotated at the rotating speed, the first coil part 12 and the second coil part 14 are wound in different winding directions.

After the two-stage coil 10 having the first coil part 12 and the second coil part 14 formed on the winding axis 120 is formed and the end of the second coil part 14 is cut, (10) is discharged from the winding shaft (120), and the end of the cut wire (1) is clamped to the wire clamp (330) again.

On the other hand, the winding axis 120 of the first coil winding unit 100 and the rotation axis 212 of the second coil winding unit 200 are rotated in the clockwise direction to have the first and second coil sections 12, When the two-stage coil 10 is formed, the electric wire 1, which is provided from the bobbin and passes through the rotation axis 212 of the second coil winding unit 200, Twisted.

When the two-stage coil 10 is again formed on the winding shaft 120 to untwist the electric wire 1, the winding shaft 120 of the first coil winding unit 100 and the winding shaft 120 of the second coil winding unit 200 The first and second coil portions 12 and 14 are formed while rotating the rotary shaft 212 in the counterclockwise direction opposite to the clockwise direction to excessively twist the electric wire 1 to thereby cause a manufacturing defect such as breakage of the electric wire 1 Can be prevented.

As described above in detail, when forming the two-stage coil having the first and second coil portions on one winding axis, the electric wire clamped by the electric wire clamped by the worker does not hold the end of the electric wire cut manually by the operator So that the productivity can be further improved. In addition, when the tension control unit coupled to the wire clamp applies a predetermined tension to the wire clamped to the wire clamp, the wire is broken due to excessive tension applied to the wire during the winding of the wire on the winding axis, And the quality of the product can be further improved.
