WIRE WINDING DEVICE, WIRE WINDING METHOD, AND COIL MANUFACTURING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/235378
Kind Code:
A1
Abstract:
This wire winding device is for winding a wire material around a winding core that rotates via a rotation mechanism, so as to manufacture a coil. The winding core includes a base plate and a plurality of hanging pins erected on the base plate, with circumferential grooves into which the wire material falls being formed respectively in the outer circumferences of the plurality of hanging pins. The rotation mechanism includes a rotating plate capable of freely rotating, a drive mechanism for causing the rotating plate to rotate, and a pair of columnar members erected on the rotating plate so as to sandwich the rotation center. The rotation mechanism also comprises an outer winding core movement mechanism, in which an inner base plate is attached to each leading end of the pair of columnar members, and an outer base plate is provided to each of the columnar members so as to be capable of moving in a rotary axis direction, thereby enabling the outer base plates to be moved.
