Description

Transformer coil winding device Technical Field The present invention relates to a coil winding apparatus of a transformer, and more particularly, to a coil winding apparatus of a transformer, in which a plurality of windings are simultaneously wound in a certain winding pattern in a bobbin and a certain winding pattern of the windings is induced, thereby preventing phenomena of rapid winding and disordered winding of the windings. Background In general, most transformers are manufactured in a multi-layer (two-layer or multi-layer) structure, wherein a coil of the structure, including primary and secondary windings according to magnetic coupling, is wound in a continuous manner around a circular or flat wire (made of rectangular copper or aluminum). In the case of winding with a rectangular conductor (hereinafter referred to as "rectangular wire"), a current to the conductor generates a large eddy current loss compared with a circular conductor of the same cross-sectional area (hereinafter referred to as "round wire"), and because of the rectangular shape, it is difficult to use a winding machine winding, and thus the operation speed is slow, which has a disadvantage of being relatively unfavorable for insulation. Therefore, in order to overcome the disadvantage of winding with rectangular wire, it is considered to wind with round wire, and when winding with round wire, a semiautomatic winding machine (see, for example, korean registered patent publication No. 20-0452392) may be used, so that the working speed is high, the difference in mass between a skilled worker and an unskilled pine is small, there is an advantage of easy wire supply, and an advantage of a small vortex pointer. But if the cross-sectional area of the round wire is greater than(4Φ), the phenomenon of increased hands of vortex compared to square lines occurs, and normal use of parallel lines occurs, in which case the existing drawbacks of rectangular lines occur. Thus, even if the cross-sectional area is larger than(4Φ) also requires the use of round wires and greatly reduces eddy current hands, e.g., windings consisting of round wires can be separated and connected in parallel. For example, the inventors have implemented arrangements on a trial basis, i.e. with a winding machine pair greater thanThe large area of (4Φ) was rounded as shown in FIG. 1. As shown in fig. 1, in the case of a round wire, in order to reduce eddy current hands, the windings are divided into two in the up-down direction (the longitudinal direction of a bobbin or core (hereinafter referred to as "core")) (1), an upper multi-layer parallel winding (2) and a lower multi-layer parallel winding (3) are arranged in parallel, each parallel winding (2) (3) is wound in multiple layers (at least 2 layers) to ensure a predetermined number of windings, and the number of layers (2) (3) of each parallel winding and the layers of each parallel winding (materials having insulating properties, mica, synthetic resin films, etc. known in the art), and the insulating member 5 can be insulated by intervention. In particular, the insulating member 5 is placed between layers of the upper and lower multi-layer parallel windings (2, 3) to perform an insulating function, respectively, the upper and lower insulating interlayers (5-1, 5-2) and the upper insulation release preventing portions (5-3) (5-4) are composed of a folded structure so that the round wire is not deviated, and is configurable by supporting each side of the upper insulating interlayer (5-1) and the lower insulation release preventing portion (5-5) (5-6) to support each side of the lower insulating interlayer (5-2) so that the round wire is not deviated. However, since one insulating member 5 is provided in each of the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), the length from the lower portion of the core or bobbin (1) to the upper portion of the core or bobbin (1) becomes longer, and the overall size of the transformer increases accordingly. In addition, independent insulating pieces 5 are respectively arranged on the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), and the insulating pieces 5 are also interposed between the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), so that the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3) cannot be wound simultaneously. Of course, it is possible to solve these problems by the technical configuration disclosed in the registered patent 10-2659159 as one way of improving these problems. However, in this registered patent 10-2659159, the size of the transformer can be greatly reduced, and a winding machine can be used to simultaneously winding the upper multi-layer parallel winding and the lower multi-layer parallel winding, which greatly shortens the working time and improves the productivity.
