Abstract

PURPOSE:To improve the winding efficiency of a coil by immersing a start wire for one layer of the coil, winding the wire by one turn along a start plate, winding the wire by specified turns in this way, and bonding and fixing pieces of the wire by self-fusion. CONSTITUTION:Self-fusing and fixing wire is used for electric wire. A start wire 10 is stored by a length required for a start flyer 8. The start wire 10 is arranged along a start plate 5. A magnet wire 11 which is the other end of the start wire 10 and is fed through a winding flyer 9 is immersed in a solvent. The winding flyer 9 is rotated. A coil 12 is wound around a winding part 7 in an aligned pattern. At every time the coil 12 is wound around the winding part 7 by one layer, the start wire 10 is immersed in the solvent. The wire is wound by every one turn along the start plate 5. Therefore, the starting lead wire of the coil and the finishing lead wire can be taken out of the upper layer of the coil. In this way, the coil is wound in an aligned and multilayered manner. The coil is made small, and the coil having the excellent winding efficiency is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multilayer coil winding method for use in small motors and the like.

[Prior Art] In recent years, as motors have become smaller and thinner, bobbin-less @flat coils have been required, and in order to improve the efficiency of motors, winding methods with high cross-sectional efficiency of the coils have been required. ing.

A conventional example will be described with reference to the drawings. FIG. 5 schematically shows a conventional winding device. In FIG. 5, a start plate (25) and an end plate (26) are attached to a shaft (24) with a winding part (27) in between. The start plate (25) is provided with a slit (25a) for drawing out the start line (31).
End Brake) (26) is removably removed by 1 inch. Start flyer (28) ζ start line (
30), put the start wire (30) into the slit (25a), rotate the winding flyer (29) to the winding section (27), and then insert the magnet wire (31) into the winding section (27).
are wound in multiple layers in an aligned manner around the coil (32).

Figure 6 shows the start plate (25) and end plate (
2G) shows the upper half of the start flyer (28),
The winding flyer (29) is omitted. Figure 6 (A
), (B), and (C) are the coil (32) in the winding part (27).
Shows the rolled state. After fixing the coil (32) with adhesive, move the start plate (25) and insert the magnet wire (
By providing a gap (-) approximately the same width as the wire diameter of 3I), rotating the start flyer (28) in the opposite direction to the rotation direction of the winding flyer 29), winding it a predetermined number of times, and fixing with adhesive. , forming a coil (21).

[Problems to be Solved by the Invention] However, with the winding method as described above, the coil (32
) After winding, fix the coil (32) with adhesive to prevent it from collapsing, then shift the start brake (25) and install the coil (32).
2), and insert the start line (2) stored in the start flyer (28) into the gap.
30) and required a complicated process of wrapping and fixing with adhesive again.

For this reason, a winding method with good productivity has been sought.

[Means for Solving the Problems] In order to solve the above problem U, an example of the winding method of the present invention will be explained.

Use self-bonding wire as the electric wire, store the start wire (10) to the start flyer (8) to the required length, and connect the start wire
! O) on the start plate (5), and rotate the wire-wound fryer (9) while soaking the magnet wire (II), which is the other end of the start wire (10) and comes out of the wire-wound fryer (9), in the solvent. The coil (12) is wound in alignment on the winding portion (7). Each time the coil (12) is wound around the winding portion (7), the start wire (10) is immersed in a solvent and applied to the start plate (5), and the coil (12) is wound one turn at a time.

[Example of real power] Hereinafter, one embodiment of the present invention will be described based on the drawings.

In figure M2, the winding section (with the start plate (5) and end plate (6) attached to the winding shaft (4)
7), and the end plate (6) is detachably provided.

The magnet wire (11) comes out of the winding flyer (9), has a start wire (10) at its tip, and is connected to the start flyer (8).

Store the start line (10) on the start flyer (8) and transfer the start line (10) to the start flyer (8)
Align the position of the magnet wire (+
1) is immersed in a solvent (lla) and wound onto the winding portion (7) one layer at a time in alignment. Further, the start wire (10) is immersed in a solvent (LOA), aligned with the winding vA section (7) in the - layer, placed on the start plate (5), and wound in turns.

FIG. 3 shows a method of forming a coil (+) by an embodiment of the winding using the winding device of the present invention shown in FIG.

In addition, Fig. 3 (A), (B), and (C) show the start plate (5), end plate (black), coil (
10) shows only the top half, start flyer (8)
and the winding flyer (9) are omitted.

As shown in FIG. 3(A), the coil (12) wraps the magnet wire (11) in one layer in alignment on the winding portion (7), hits the end plate (6), and turns back to wind the second layer. The second layer coil (12) is connected to the start plate (5
) until the start line (10) is aligned with the start plate (5), and the magnet wire (11
) Wrap once in the opposite direction.

As shown in FIG. 3(B), every time the coil (12) is wound one layer, the start wire (10) is aligned with the start plate (5) and the coil (12) is wound once. FIG. 3 <C> is a diagram of the winding completed.

Incidentally, since the start wire and the magnet wire are wound while being soaked in a solvent, the coil can be adhesively fixed without any post-processing, and the coil can be removed by removing the removably provided end plate.

In addition, as a method of taking out the start wire of the coil from the upper layer, by storing a large amount of start wire in the start flyer, the start wire can be wound on top of the windings wound in alignment in the lower layer. , wind the magnet wire one round trip on top of it. There is a method in which the wire is wound alternately one round trip at a time.

[Effects of the Invention] As described above, the present invention improves the start of the coil by winding the start wire once along the start plate each time the coil is wound between the start plate and the end plate. The lead wire and finish wire can be pulled out from the upper layer of the coil.This allows the coil to be wound in multiple layers in an aligned manner, making it possible to supply coils for use in motors, etc., which are compact and have high winding efficiency. It is valid.
