Document Type and Number:
WIPO Patent Application WO/2021/205951
Kind Code:
A1
Abstract:
A coil manufacturing device comprising: a holding unit (11) having a plane (11A) for holding a coil wire (1); a rotating unit (14) for rotating a spool (13) disposed on a rotating axis (Q); and a pressing unit (15) for causing the relative positions of the spool (13) and the plane (11A) of the holding unit (11) to be moved in a vertical direction (Y) perpendicular to both the plane (11A) of the holding unit (11) and an axial direction (Z) of the rotating unit (14). The pressing unit (15), while causing the relative positions of the plane (11A) of the holding unit (11) and the spool (13) to be changed in the vertical direction (Y) so as to sandwich the coil wire (1) between the plane (11A) of the holding unit (11) and the spool (13), presses the coil wire (1) from the vertical direction (Y) at the plane (11A) of the holding unit (11) and the spool (13), and the rotating unit (14) causes the spool (13) to rotate to wind the coil wire (1) around the spool (13).
