Winding apparatus and coil component manufacturing method

A winding apparatus for a coil component in which wires are wound around a core, the winding apparatus comprising:

• a wire position support including wire route holes in which the wires are inserted;
• a wire feeder that feeds the wires to the wire position support such that tension is applied to the wires;
• a winding driver that orbitally revolves the wire position support around the core such that the wires are wound around the core while twisted;
• and
• a controller that controls the winding driver, such that the controller performs
• first control, in which the core is not rotated but the wire position support is orbitally revolved in a first rotation direction with respect to the core, and
• second control, in which the core is rotated and the wire position support is orbitally revolved in a second rotation direction with respect to the core that is of an opposite direction to the first rotation direction,
• and the controller switches between the first control and the second control based on a predetermined condition,
• wherein in the second control, the controller sets the rotation speed of the core faster than the orbital revolution speed of the wire position support.

A method for manufacturing a coil component in which wires are wound around a core, the coil component manufacturing method comprising:

• a core preparation process of preparing the core;
• a winding starting process of hooking a winding starting end in the wires inserted in wire route holes of a wire position support on an electrode corresponding to the winding starting end in the core while tension is applied to the wires by a wire feeder;
• a winding process of orbitally revolving the wire position support in an opposite direction to a rotation direction of the core while rotating the core, and winding the wires around the core while twisting the wires;
• a winding ending process of hooking a winding ending end in the wires on an electrode corresponding to the winding ending end in the core;
• and
• a fixing process of fixing the winding starting end to the electrode corresponding to the winding starting end in the core, and fixing the winding ending end to the electrode corresponding to the winding ending end in the core,
• such that in the winding process, switching between first control and second control is performed based on a predetermined condition
• the first control, in which the wire position support is orbitally revolved in a first rotation direction and the core is rotated in a second rotation direction that is of an opposite direction to the first rotation direction, and
• the second control, in which the wire position support is orbitally revolved in the second rotation direction and the core is rotated in the first rotation direction.
