AI Technical Summary
Technical Problem
Existing stator winding devices face issues with wire loosening during the winding process, particularly due to the movement of the head support shaft, which can cause the wire to become caught or fail to maintain tension effectively.
Method used
A stator manufacturing apparatus with a nozzle that feeds wire around magnetic poles, incorporating a tension device, a cylindrical nozzle holding portion, and a guide member with an R-shaped section to change the wire direction, ensuring tension is maintained and preventing loosening.
Benefits of technology
The apparatus ensures stable wire winding by maintaining tension and preventing slack, improving space utilization and motor efficiency by allowing for quick wire feeding and simplified wire attachment processes.

Abstract
A winding device (100) comprises: a nozzle (11) that is for feeding out a wire (2) while moving relatively to a stator core (10) and that is for winding the fed out wire (2) onto teeth (10b) of the stator core (10); a tensioning device (80) that tensions the wire (2) which is supplied to the nozzle (11); a head support shaft (13) that supports the nozzle (11) and that has a through hole (13a) through which the wire (2) supplied to the nozzle (11) from the tensioning device (80) passes; and a cylindrical guide member (60) that has an R part (63) which changes the direction of the wire (2) guided from the tensioning device (80) to the head support shaft (13), and is provided so as to be incapable of moving coaxially with the head support shaft (13).
