Coil winding device and method for manufacturing coil
A coil winding device includes a wire rod delivering machine configured to deliver a wire rod through a nozzle, a wire storing jig configured to store the wire rod delivered from the nozzle, a wire-wound member around which the wire rod is wound, a wire-wound-member rotation mechanism configured to rotate the wire-wound member to wind the wire rod delivered from the nozzle around the wire-wound member, and a wire-storing-jig turning mechanism configured to turn the wire storing jig around a rotation axis of the wire-wound member to wind the wire rod delivered from the wire storing jig around the wire-wound member. The rotation axis of the wire-wound member and a wire-storing central axis of the wire storing jig are mutually orthogonal.
1. A coil winding device comprising:
a wire rod delivering machine configured to deliver a wire rod through a nozzle;
a wire storing jig configured to store the wire rod delivered from the nozzle;
a wire-wound member around which the wire rod is wound;
a wire-wound-member rotation mechanism configured to rotate the wire-wound member to wind the wire rod delivered from the nozzle around the wire-wound member; and
a wire-storing-jig turning mechanism configured to turn the wire storing jig around a rotation axis of the wire-wound member to wind the wire rod delivered from the wire storing jig around the wire-wound member, wherein:
the wire rod is a rectangular wire rod whose cross-sectional shape is rectangular, and
the rotation axis of the wire-wound member and a wire-storing central axis of the wire storing jig are mutually orthogonal.
2. The coil winding device according to claim 1 , wherein:
the wire storing of the wire storing jig is performed such that the rectangular wire rod is wound to be curved in a thickness direction, and
the winding of the wire rod around the wire-wound member is a winding over of the rectangular wire in a width direction.
3. A method for manufacturing a coil, comprising:
storing a wire rod delivered from a nozzle in a wire storing jig;
rotating a wire-wound member to wind the wire rod delivered from the nozzle around the wire-wound member; and
turning the wire storing jig around a rotation axis of the wire-wound member to wind the wire rod delivered from the wire storing jig around the wire-wound member, wherein:
the wire rod is a rectangular wire rod whose cross-sectional shape is rectangular, and
the rotation axis of the wire-wound member and a wire-storing central axis of the wire storing jig are mutually orthogonal.
4. The method for manufacturing the coil according to claim 3 , wherein:
the wire storing of the wire storing jig is performed such that the rectangular wire rod is wound to be curved in a thickness direction, and
the winding of the wire rod around the wire-wound member is performed such that the rectangular wire rod is wound over in a width direction.
