AI Technical Summary

Technical Problem

Existing winding devices face issues with scratches and defects due to changes in cross-sectional shape during winding, requiring excessive drawing force and complicating the connection process for start and end terminals, especially with varying stator core shapes and reduced winding lengths.

Method used

A winding device with a shortened pass line configuration, incorporating a shaping unit that forms rectangular wire sections while leaving start and end portions round, and a tension adjustment unit with large diameter tension rollers to prevent slippage and stabilize wire drawing, using an encoder to monitor and control wire length.

Benefits of technology

The device ensures stable winding without defects, reduces slippage, and allows easier connection by positioning start and end terminals correctly, even with varying stator core shapes and shorter winding lengths.

Abstract

To provide a winding device with a short distance of a path line from a molding part for molding a wire to a winding object.SOLUTION: A winding device 10 according to the present invention comprises: a wire supply part 11 for supplying a round-shaped wire; a molding part 12 provided on a downstream side of the wire supply part 11 and molding a shape of the wire into a rectangular shape; a tension adjusting part 13 provided on a downstream side of the molding part 12 and controlling tension during winding; and a winding part 14 provided on a downstream side of the tension adjusting part 13 and winding the wire around a winding object. The molding part 12 does not mold portions of the wire corresponding to start and end terminals of the winding object, and molds the wire corresponding to a wound portion of the winding object. The tension adjusting part 13 comprises a tension roller, and a motor for rotating the tension roller. The tension roller has a grip force for pulling the wire from the molding part 12 without slippage between the roller and the wire.SELECTED DRAWING: Figure 3
