Method for manufacturing coil component
A method for manufacturing a coil component includes: preparing a wound coil, a first jig and a second jig; disposing the wound coil on the first jig; and pressing the wound coil, wherein the pressing the wound coil includes bringing the first jig and the second jig into contact with each other by a first rotation of the first jig.
1 . A method for manufacturing a coil component, comprising:
preparing a wound coil, a first jig and a second jig;
disposing an entirety of the wound coil on the first jig; and
pressing the wound coil by bringing the first jig and the second jig into contact with each other through a first rotation of the first jig,
wherein the first jig includes a support portion, a core pin formed on the support portion, and first and second pressing portions each having an inner surface, the inner surfaces of the first and second pressing portions of the first jig are opposing each other, while having the core pin interposed in-between the inner surfaces, and
the entirety of the wound coil is wound around along an outer surface of the core pin and disposed between the first pressing portion and the second pressing portion on the support portion and fixed to the core pin.
2 . The method of claim 1 , wherein the wound coil includes a wound portion and a lead-out portion, and
in the pressing the wound coil, the first and second pressing portions move toward the core pin to bring the inner surface of each of the first and second pressing portions into contact with the wound portion, thereby pressing the wound coil in a width direction.
3 . The method of claim 2 , further comprising moving the first jig and the second jig away from each other by a second rotation of the first jig after the pressing the wound coil.
4 . The method of claim 3 , wherein the first rotation of the first jig is performed in a first direction, based on a central axis of the first jig, and
the second rotation of the first jig is performed in a second direction opposite to the first direction, based on the central axis of the first jig.
5 . The method of claim 4 , wherein the first direction is a clockwise direction, and the second direction is a counterclockwise direction.
6 . The method of claim 4 , wherein the first jig further includes first and second contact portions each connected to an outer surface of each of the first and second pressing portions, and
in the bringing the first jig and the second jig into contact with each other by the first rotation of the first jig, the first and second contact portions are in contact with the second jig.
7 . The method of claim 6 , wherein the second jig includes a holder, a rotation portion disposed on the holder, and a bearing disposed on the rotation portion, and
in the bringing the first jig and the second jig into contact with each other by the first rotation of the first jig, the first and second contact portions are in contact with the bearing of the second jig.
8 . The method of claim 7 , wherein the second jig further includes a fix portion fixing the rotation portion to the holder, and
in the bringing the first jig and the second jig into contact with each other by the first rotation of the first jig, the rotation portion is rotated counterclockwise based on the fix portion.
9 . The method of claim 8 , wherein in the bringing the first jig and the second jig into contact with each other by the second rotation of the first jig, the rotation portion is rotated clockwise based on the fix portion.
10 . The method of claim 9 , wherein first and second grooves are respectively formed in the first and second pressing portions,
the first jig includes first and second springs respectively disposed in the first and second grooves, and
the first and second springs are retracted when the first jig performs the first rotation.
11 . The method of claim 10 , wherein in the moving the first jig and the second jig away from each other by the second rotation of the first jig, the retracted first and second springs are relaxed to move the first and second pressing portions away from the wound coil.
12 . The method of claim 3 , wherein the first and second pressing portions each includes a protrusion, and
in the pressing the wound coil, the first and second pressing portions are moved for the protrusion of each of the first and second pressing portions to be in contact with the lead-out portion, thereby pressing the wound coil.
13 . The method of claim 3 , further comprising:
disposing the wound coil in a recess of a tray before the disposing of the entirety of the wound coil on the first jig, and
disposing the wound coil in a recess of a frame after the moving of the first jig and the second jig away from each other by the second rotation of the first jig.
14 . The method of claim 13 , further comprising stacking a magnetic sheet on one surface and another surface of the frame.
15 . The method of claim 14 , further comprising dicing the frame and the magnetic sheet.
16 . The method of claim 1 , wherein the support portion further includes a suction portion to prevent the wound coil from being misaligned or falling off by impact.
17 . The method of claim 16 , wherein the suction portion is connected to an exhaust portion of the first jig to suck air away from the suction portion toward the outside, thereby generating a vacuum state.
18 . The method of claim 1 , wherein the coil wound after the pressing the wound coil has an outer diameter (W A2 ) and an inner diameter (W B2 ) each smaller than an outer diameter (W A1 ) and an inner diameter (W B1 ) of the wound coil before the pressing the wound coil.
19 . A method for manufacturing a coil component, comprising:
preparing a wound coil, a first jig and a second jig;
disposing an entire part of the wound coil on the first jig;
pressing the wound coil by bringing the first jig and the second jig into contact with each other through a first rotation of the first jig; and
moving the first jig and the second jig away from each other by a second rotation of the first jig after the pressing the wound coil;
wherein the first jig includes a support portion, a core pin formed on the support portion, and first and second pressing portions each having an inner surface, the inner surfaces of first and second pressing portions are opposing each other, while having the core pin interposed in-between the inner surfaces, and
the entire part of the wound coil is disposed between the first pressing portion and the second pressing portion on the support portion and fixed to the core pin,
the wound coil includes a wound portion and a lead-out portion,
in the pressing the wound coil, the first and second pressing portions move toward the core pin to bring the inner surface of each of the first and second pressing portions into contact with the wound portion, thereby pressing the wound coil in a width direction,
the first rotation of the first jig is performed in a first direction, based on a central axis of the first jig,
the second rotation of the first jig is performed in a second direction opposite to the first direction, based on the central axis of the first jig,
the first jig further includes first and second contact portions each connected to an outer surface of each of the first and second pressing portions,
in the bringing the first jig and the second jig into contact with each other by the first rotation of the first jig, the first and second contact portions are in contact with the second jig,
the second jig includes a holder, a rotation portion disposed on the holder, and a bearing disposed on the rotation portion, and
in the bringing the first jig and the second jig into contact with each other by the first rotation of the first jig, the first and second contact portions are in contact with the bearing of the second jig.
