Abstract

A method for manufacturing a coil component that can contribute to prevention of durability degradation of a wire. The method includes winding a plurality of wires, that are supplied from a wire supply source to a nozzle through a tensioner, around a core by revolving the core around the nozzle. Also, during the winding, the core is rotated in a direction same as or opposite to a revolution direction of the core.

First claim

What is claimed is:

1. A method for manufacturing a coil component, the method comprising:
winding wires, supplied from a wire supply source to a nozzle through a tensioner, around a core by revolving the core around the nozzle.

2. The method for manufacturing a coil component according to claim 1 , wherein during the winding, the core is rotated in a direction same as or opposite to a revolution direction of the core.

3. The method for manufacturing a coil component according to claim 2 , wherein during the winding, the core is rotated in the direction same as the revolution direction of the core.

4. The method for manufacturing a coil component according to claim 2 , wherein during the winding, the core is rotated in the direction opposite to the revolution direction of the core.

5. A winding device that manufactures a coil component in which wires are wound around a core, the winding device comprising:
a nozzle in which the wires pulled out from a wire supply source are inserted;
a tensioner configured to adjust tension of the wires inserted in the nozzle;
a holder configured to hold the core;
a revolution driver configured to revolve the core around the nozzle; and
a first controller configured to control the revolution driver to revolve the core around the nozzle, and wind the wires inserted in the nozzle around the core.

6. The winding device according to claim 5 , further comprising:
a rotation driver configured to rotate the core in a direction same as or opposite to a revolution direction of the core as revolved by the revolution driver; and
a second controller configured to control the rotation driver to rotate the core when the first controller controls the revolution driver to revolve the core around the nozzle.

7. The winding device according to claim 6 , wherein:
the second controller is configured to control the rotation driver to rotate the core in the direction same as the revolution direction of the core when the first controller controls the revolution driver to revolve the core around the nozzle.

8. The winding device according to claim 6 , wherein:
the second controller is configured to control the rotation driver to rotate the core in the direction opposite to the revolution direction of the core when the first controller controls the revolution driver to revolve the core around the nozzle.
