[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for processing a winding start end of a rectangular wire coil used for manufacturing a rectangular wire coil as a component of a flat type motor incorporated in, for example, a video camera or a headphone stereo. It is about.

[0002]

2. Description of the Related Art Conventionally, in winding a rectangular wire of this type, as shown in FIG. 21, an adhesive action is produced by heating or a solvent on the peripheral surface of a conductor layer a made of copper foil via an insulating layer b. A width of 0.2 mm or more formed by forming the adhesive layer c in a laminated shape
Using a flat wire W having a thickness of 2.0 mm and a thickness of 20 μm to 200 μm, the flat wire W is sequentially sent from the supply unit to the outer peripheral surface of a winding core having an arbitrary cross-sectional shape, and the winding core is rotated by rotating the main shaft. Then, the flat wire is wound on the outer peripheral surface of the winding core into a flat wound coil shape having a straight line width, as shown in FIG.
So that the production of flat wire coils S formed by the terminal portions W ₁ and outer terminal portions W ₂ among reaching the conductive layer a peeled formed in the arbitrary shape.

[0003]

However, in the case of the above-mentioned conventional structure, as shown in FIG. 22, in the structure of fixing the winding start end of the flat wire to the winding core p and cutting off the starting end,
A wire insertion gap h is formed in the winding core p, and a half-split crumb member m capable of pinching and holding the flat wire W is rotatably mounted in the center thereof. The rectangular wire W is fixed to the winding core p by being clamped by the clamping member m, and the winding core p is wound and rotated in this fixed state, and the flat wire is wound to the winding core p. The winding member is wound around the outer peripheral surface an arbitrary number of times, and then, after winding is completed, as shown in FIG. 23, the clamp member m is rotated within the winding core p, and this rotation causes the edge of the wire insertion gap h to move. The rectangular wire W is cut as a cutting blade k by pulling it.
After the start terminal is cut, the wound rectangular wire coil S is configured to be transferred to an unloader member (not shown), and a clamp member is inserted into the inner hole of the wound rectangular wire coil for the tensile cutting. start terminal of the rectangular wire leading to m is may remain in free protruding, therefore, it is necessary to remove the remaining starting terminal in the inner hole S ₁ of the rectangular wire coil S artificially or mechanically, winding operation Since the clamping member m is incorporated in the winding core p so as to be able to pinch, the winding core p and the clamping member m have a very small shape. It has the disadvantage that it is apt to be complicated and may be damaged and lack the reliability of operation.
