3 and 4 are a side view and a front view for explaining the operation of the non-winding low voltage coil winding apparatus according to the embodiment of the present invention.

1 to 4, an unshrouded low-voltage coil winding apparatus 1 (hereinafter, referred to as a winding apparatus) according to an embodiment of the present invention includes a coil bobbin B wound around a coil C used in a transformer, And may be a device for winding the coil C and providing space for winding the coil C and winding lead P or Q.

The parallel rotation shaft 10 may be disposed parallel to the rotation axis B1 of the coil bobbin B for winding the coil C wound around the coil bobbin B.

The parallel rotating shaft 10 may be rotated in one direction so that the coil C wound from the coil bobbin B is wound around the inner diameter determining portion 20 and the space providing portion 30 .

The inner diameter determining portion 20 is a portion of the coil C that is mounted on the parallel rotation shaft 10 and is expanded radially outward about the parallel rotation shaft 10 or folded inward in the radial direction, The inner diameter can be determined.

Specifically, the space providing part 30 includes a mounting part 37 mounted on the parallel rotation shaft 10 and rotated about the parallel rotation axis 10, and a mounting part 37 connected to an end of the mounting part 37, And may have a flat surface 39 providing the plane.

Specifically, the mounting portion 37 is rotated about the parallel rotation axis 10 at a third position (see FIG. 3) arranged parallel to the parallel rotation axis 10, (See FIG.

The movement of the rotation portion 27 from the first position to the second position and the movement of the mounting portion 37 from the third position to the fourth position can be realized at the same time.

The inner diameter determining unit 20 of the winding apparatus 1 according to the embodiment of the present invention includes a first inner diameter determining unit 21 disposed in the longitudinal direction of the parallel rotation shaft 10, An inner diameter determination section 22 and a third inner diameter determination section 23 may be provided.

The first inner diameter determining portion 21 includes a first inner diameter determining portion 211 radially arranged along the outer peripheral surface of the parallel rotating shaft 10, a first inner diameter determining portion 212, 3 inner diameter determination unit 213. [0033]

The first to third inner diameter determining portion 213 includes a first to third turning portions 213a mounted on the parallel rotation axis 10 and rotated about the parallel rotation axis 10, -3 winding portion 213b connected to the end of the third turning portion 213a and providing the bent surface.

The imaginary curved surface connecting the curved surfaces formed by the 1-1 turn portion 211b, the 2-1 turnover portion 221b, and the 1-3 turnover portion 213b forms a circular shape having a certain curvature can do.

The second inner-diameter determining portion 22 includes a second-1 inner-diameter determining portion 221, a second-2 inner-diameter determining portion 20, and a second inner-inner-diameter determining portion 20 radially arranged along the outer peripheral surface of the parallel- And an inner diameter determining unit 20 may be provided.

The 2-1 inner diameter determining portion 221 includes a 2-1 turn portion 221a mounted on the parallel rotation shaft 10 and rotated about the parallel rotation axis 10, And a second winding section 221b connected to an end of the turning section 221a and providing the bent surface.

The rotating direction of the first-first rotating portion 211a, which is rotated with respect to the parallel rotating shaft 10, and the rotating direction of the third-first rotating portion 231a, which is rotated with respect to the parallel rotating shaft 10, Can be different.

This is because the turning direction of the 1-1 -rotating portion 211a with respect to the parallel rotating shaft 10 and the turning direction of the 3-1-turning portion 231a with respect to the parallel rotating shaft 10 So that the turning portion 27 is prevented from being covered by the external force applied in the one direction.

In other words, the external force applied to the rotary part 27 is partially dispersed by making the turning direction of the first-first rotary part 211a different from the turning direction of the third-first rotary part 231a, So that all the turning portions 27 are not covered.

Thus, the coil C wound by the winding apparatus 1 of the present invention can be commercialized while maintaining the predetermined inner diameter and tension.

The space providing unit 30 includes a first space providing unit 31, a second space providing unit 32, and a third space providing unit 32, which are spaced apart from each other along the longitudinal direction of the parallel rotation shaft 10 33 may be provided.

The pivoting direction of the first mounting portion 311 pivoting about the parallel rotation shaft 10 may be different from the pivoting direction of the third mounting portion 331 pivoting about the parallel rotation axis 10. [

This is because the first mounting portion 311 is made to have a coating direction with respect to the parallel rotation axis 10 and a third coating portion 331 with a reference coating direction based on the parallel rotation axis 10, So that the mounting portion 37 is prevented from being covered by the external force applied in the direction.

In other words, the external force applied to the mounting portion 37 is partially dispersed by making the first mounting portion 311 and the third mounting portion 331 different from each other so that all the mounting portions 37 are overlapped .

Thus, the coil C wound by the winding apparatus 1 of the present invention can be commercialized while maintaining the predetermined inner diameter and tension.

5 and 6 are front views for explaining an inner diameter determining portion of a non-winding low voltage coil winding apparatus according to an embodiment of the present invention.

5 and 6, the winding unit 29 of the winding apparatus 1 according to the embodiment of the present invention has the length of the winding unit 29 changed from the rotation unit 27 to the parallel rotation axis 10, The contact area with the coil C that is wound in accordance with the change in the inner diameter of the coil C to be wound according to the separation distance from the coil C can be changed.

More specifically, when the separation distance from the parallel rotation shaft 10 is increased, the winding section 29 has a longer length with respect to the rotation section 27, and the separation distance from the parallel rotation axis 10 The length can be shortened on the basis of the turning portion 27. [

This is because when the winding unit 29 is moved away from the parallel rotary shaft 10 due to the long length of the rotary part 27, that is, when the inner diameter of the winding coil C is increased by the winding device 1, So that the contact area with the winding coil C is widened so as to keep the winding coil C in a circular shape.

In other words, as the inner diameter of the winding coil C becomes larger, it may be difficult to form the winding coil C by the winding portion 29. However, in the present invention, as the inner diameter of the winding coil C becomes larger By making the length of the winding portion 29 longer, the roundness of the winding coil C can be formed more easily.

7 and 8 are front views for explaining a space providing portion of a non-winding low voltage coil winding apparatus according to an embodiment of the present invention.

7 and 8, the plane portion 39 of the winding apparatus 1 according to the embodiment of the present invention is formed such that the length thereof is changed with respect to the mounting portion 37, The size of the plane may be changed according to the size of the planes Q, Q.

More specifically, the plane portion 39 is formed so that the size of the plane of the winding lead P or the winding lead Q, which is mounted on the coil C wound by the winding apparatus 1 of the present invention, The length can be changed with reference to the mounting portion 37 depending on the width of the lead wire and the lead wire lead (P, Q).

9 is a front view for explaining a parallel rotary shaft of a non-winding low-voltage coil winding apparatus according to an embodiment of the present invention.

9, the parallel rotation shaft 10 of the non-winding low-voltage coil winding apparatus 1 according to the embodiment of the present invention is formed such that the coil C wound from the coil bobbin B is wound around the inner- When the coil C wound from the coil bobbin B is wound on the space providing portion 30 in the one direction by rotating the coil bobbin B in the one direction And may be rotated at a second speed V2 that is less than the first speed V1.

Specifically, when the coil C wound from the coil bobbin B is wound around the inner diameter determining portion 20, the coil C is wound around the bent inner portion of the inner diameter determining portion 20, 20 may be wound while maintaining the tension along the curved circular shape of the spatula 20, but when the spatters are wound on the space providing portion 30, they provide a shorter plane than the curved circular shape, It is possible to wind the space providing portion 30 in a state where the tension is not held.

In order to solve this problem, when the coil C wound from the coil bobbin B is wound around the inner diameter determining portion 20, the parallel rotation shaft 10 is rotated When the coil C wound from the coil bobbin B is wound on the space providing portion 30, the parallel rotation shaft 10 is rotated at the first speed V1 ) At a second speed (V2) smaller than the first speed (V2).

For this purpose, it is natural that the rotation axis of the coil bobbin B should be rotated at the same speed as the parallel rotation axis 10.

When the manufacture of the coil C wound by the low-pressure low-voltage coil winding apparatus 1 of the present invention is completed, the rotary section 27 returns from the second position to the first position, and the mounting section 37 May return from the fourth position to the third position.

Thus, the space expanded around the parallel rotary shaft 10 by the rotary part 27 and the mounting part 37 is contracted and is wound around the inner diameter determination part 20 and the space providing part 30 The coil C can be easily separated from the inner diameter determining portion 20 and the space providing portion 30.
