Apparatus for producing winding of stator coil

摘要

A stator coil winding is produced by supplying a wire to a winding frame from a nozzle, holding a terminal end of the wire with a holding device, rotating the winding frame with a driving device to wind the wire around the winding frame while the nozzle is moved by a nozzle-moving device parallel to a rotary shaft of the winding frame, holding a terminal end of the wire wound around the winding frame with the holding device after the wire is completely wound around the winding frame, and carrying the completely wound winding frame to a coil insertion jig with a transferring device. The winding frame is separated into winding frame elements at a face orthogonal to the rotary shaft of the winding frame, and the winding frame elements are rotated about a fulcrum in a vicinity of the face to thereby hold the separated winding frame elements so that rotary shafts of the separated winding frame elements are parallel to each other, by a handling mechanism. A coil formed by the wire wound around each separated winding frame is moved to the insertion jig by a coil-moving mechanism, and the transferred coils on the insertion jig are inserted in to a stator core by an insertion device. An apparatus for carrying out the above includes the above devices and mechanisms.
