Method of manufacturing winding-type electronic component
A method of manufacturing a winding-type electronic component using stranded wires which can suppress a disconnection of a winding when a plurality of windings is twisted. The method of manufacturing a winding-type electronic component includes: a preparation step of allowing a chuck to hold a core having a winding core portion ( 14 ) and flange portions; a first step of fixing a portion of each of windings supplied from nozzles (N 1 , N 2 ) to the flange portion; and a second step of twisting the windings by rotating the chuck.
1. A method of manufacturing a winding-type electronic component comprising:
allowing a rotatable chuck to hold a core having a winding core portion extending in a first direction and flange portions respectively provided on opposite ends of the winding core portion in the first direction;
fixing a portion of each of a plurality of windings supplied from a nozzle to one of the flange portions; and
twisting the plurality of windings together by rotating the chuck about a central axis of the winding core portion which is parallel to the first direction before winding the plurality of windings around the winding core portion about the central axis.
2. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the fixing of the portion of each of the plurality of windings is performed by thermally pressure-bonding the plurality of windings to electrodes provided on the flange portions.
3. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the fixing of the portion of each of the plurality of windings is performed by pressing the plurality of windings against the electrodes provided on the flange portions.
4. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the fixing of the portion of each of the plurality of windings is performed by hooking the plurality of windings to corner portions of the flange portions.
5. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the number of the plurality of windings is three or more.
6. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the method comprises twisting the plurality of windings by rotating the chuck without rotating the nozzle.
7. The method of manufacturing a winding-type electronic component according to claim 1 , wherein
the method comprises twisting the plurality of windings together by rotating the chuck while positioning the nozzle at a position in one side with respect to the core in the first direction before winding the plurality of windings around the winding core portion.
8. The method of manufacturing a winding-type electronic component according to claim 1 , wherein the method comprises twisting the plurality of windings together to form one stranded wire by rotating the chuck before winding the one stranded wire around the winding core portion.
