絶縁被覆された導体と、当該絶縁被覆された導体が配置される導体配置部を有するコイル部品本体とを有するコイル部品の製造方法としては、例えば、絶縁被覆された導体の当該絶縁被覆の剥離と、当該絶縁被覆が剥離された導体の導体配置部への配置とを一連の流れで行う製造方法及び製造装置が知られている。 As a method of manufacturing a coil component having an insulation-coated conductor and a coil component body having a conductor placement portion on which the insulation-coated conductor is disposed, for example, peeling of the insulation coating of the insulation-coated conductor A manufacturing method and a manufacturing apparatus are known in which a conductor from which the insulating coating is peeled is arranged in a series of flows on a conductor arrangement portion.

特開２００４−１５８５４８号公報（特許文献１）にはこのようなコイル部品の製造方法及び製造装置が記載されている。先素材ボビンに巻回された絶縁被覆導線は先素材ボビンから繰り出され、皮膜剥離機構により所定の間隔をおいて部分的に絶縁被覆が剥離される。部分的に絶縁被覆が剥離された導線は線送り機構により送られ、巻軸において巻取られて空芯コイルが形成される。

The insulation coated conductor wound around the previous material bobbin is fed out from the previous material bobbin, and the insulation coating is partially peeled at a predetermined interval by the film peeling mechanism.

しかし、従来のコイル部品の製造方法、製造装置では、上述のように絶縁被覆を剥離する皮膜剥離機構と空芯コイルを形成する部分との間に線送り機構が配置されて絶縁被覆導線が送られており、皮膜剥離機構と空芯コイルを形成する部分との間の物理的距離が大きく、また、絶縁被覆導線が皮膜剥離機構から空芯コイルを形成する部分へと送られるまでの時間が長かった。また、線送り機構よりも絶縁被覆導線が送られてくる上流側において絶縁被覆導線が剥離されるため、剥離された絶縁被覆の粕が導線に付着し、当該粕が線送り機構を通過するときに線送り機構に付着し堆積する。これらのことから、コイルにおける所定の位置に絶縁被覆が剥離された部分である剥離部を高い精度で配置することは困難であった。 However, in the conventional coil component manufacturing method and manufacturing apparatus, as described above, the wire feeding mechanism is disposed between the film peeling mechanism for peeling the insulating coating and the portion for forming the air-core coil, and the insulating coated conductor is fed. The physical distance between the film peeling mechanism and the part forming the air core coil is large, and the time until the insulation-coated conductor is sent from the film peeling mechanism to the part forming the air core coil is large. It was long. Also, since the insulated coated conductor is peeled off upstream of the wire feeding mechanism where the insulated coated conductor is sent, the peeled insulation coated wrinkles adhere to the conducting wire, and the wrinkles pass through the wire feeding mechanism Adheres to the wire feed mechanism and accumulates. For these reasons, it has been difficult to place the peeling portion, which is a portion where the insulating coating is peeled, at a predetermined position in the coil with high accuracy.

特に、絶縁被覆導線が細く絶縁被覆導線が微小なコア等のコイル部品本体上の所定の位置に配置される場合には、当該絶縁被覆が剥離された箇所たる剥離部を高い精度でコイル部品本体上の所定の位置に配置させる必要があるが、このような場合に上述したコイル部品の製造方法、製造装置を使用してコイル部品を製造することは困難であった。 In particular, when the insulation-coated conductor is thin and the insulation-coated conductor is disposed at a predetermined position on the coil component body such as a fine core, the peeling part which is the part where the insulation coating has been separated is highly accurate. In this case, it is difficult to manufacture the coil component by using the above-described method and apparatus for manufacturing the coil component.

First, the coil component will be described with reference to FIGS. The coil component is a common mode filter manufactured by a coil component manufacturing method and a coil component manufacturing apparatus, which will be described later. The coil component 1 includes a drum type core 2 and a drum type core 2 as shown in FIG. The plate-like core 20 is placed so as to cover the core portion.

ドラムタイプコア２は、長手方向に直交する断面が略長方形の巻芯部３と、巻芯部３の長手方向両端に設けられ略同一形状の鍔部４、４とを有して構成されている。巻芯部３には、２本の導線７、８が巻回されている。以下、ドラムタイプコア２の両側に位置している鍔部４は同一形状であるため、特に明記しない限り片側のみで説明する。また、巻芯部３の長手方向をｘ軸方向、巻芯部３の幅方向をｙ軸方向、ｘ軸方向とｙ軸方向とに直交する方向をｚ軸方向と定義して説明する。ドラムタイプコアはコイル部品本体に相当する。 The drum-type core 2 includes a core portion 3 having a substantially rectangular cross section perpendicular to the longitudinal direction, and flanges 4 and 4 that are provided at both ends in the longitudinal direction of the core portion 3 and have substantially the same shape. Yes. Two conducting wires 7 and 8 are wound around the core portion 3. Hereinafter, since the flanges 4 positioned on both sides of the drum type core 2 have the same shape, only one side will be described unless otherwise specified. The longitudinal direction of the core part 3 is defined as the x-axis direction, the width direction of the core part 3 is defined as the y-axis direction, and the direction orthogonal to the x-axis direction and the y-axis direction is defined as the z-axis direction. The drum type core corresponds to the coil component body.

一対の鍔部４は、Ｘ軸方向における巻芯部３の両端に巻芯部３と一体的に設けられている。鍔部４は略直方体形状をなしており、６つの面４Ａ〜４Ｆを有している。頂面４Ａと底面４Ｂとは、Ｚ軸方向において互いに対向している。第１の側面４Ｃと第２の側面４Ｄとは、Ｙ軸方向において互いに対向している。また、外端面４Ｅと第一規制面４Ｆとは、Ｘ軸方向において互いに対向している。また鍔部４は、第一規制面４Ｆの側に、後述の傾斜面９と傾斜面１０とを有している。 The pair of flange portions 4 are provided integrally with the core portion 3 at both ends of the core portion 3 in the X-axis direction.

The first side surface 4C and the second side surface 4D face each other in the Y-axis direction. Further, the outer end surface 4E and the first restriction surface 4F are opposed to each other in the X-axis direction. Moreover, the collar part 4 has the below-mentioned inclined surface 9 and the inclined surface 10 in the 1st regulation surface 4F side.

第一規制面４Ｆは、巻芯部３側に位置する面である。この第一規制面４Ｆは、ドラムタイプコア２上に板状コア２０が載置され、板状コア２０がｘ軸方向に移動させられようとしたとき、後述する第一凸部２１と当接することにより、板状コア２０のｘ軸方向の動きを規制する役割を果たす。 The first restriction surface 4F is a surface located on the core part 3 side.

コア支持部１０１０は、図３に示されるように、ドラムタイプコア２の一方の鍔部４−１を保持することができるように構成されている。また、コア支持部１０１０は図示せぬ回転装置により支持されており、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を回転軸として回転するように構成されている。導線７、８をドラムタイプコア２の巻芯部３に巻回するときに、ドラムタイプコア２をコア支持部１０１０で支持した状態で回転することにより、ドラムタイプコア２も巻芯部３の軸心を回転軸として回転し、ノズル１０２０から繰出される導線７、８が巻芯部３に巻回される。コア支持部１０１０は本体支持部に相当する。図示せぬ回転装置は巻回手段に相当する。 The core support part 1010 is comprised so that the one collar part 4-1 of the drum type core 2 can be hold | maintained as FIG. 3 shows. The core support portion 1010 is supported by a rotating device (not shown) and is configured to rotate about the axis of the core portion 3 of the drum type core 2 supported by the core support portion 1010 as a rotation axis. . When the conducting wires 7 and 8 are wound around the core portion 3 of the drum type core 2, the drum type core 2 is also rotated by the core support portion 1010 while the drum type core 2 is supported by the core support portion 1010. The lead wires 7 and 8 fed out from the nozzle 1020 are wound around the core portion 3 by rotating around the axis. The core support portion 1010 corresponds to a main body support portion. A rotating device (not shown) corresponds to the winding means.

コア支持部１０１０には、図３に示されるように、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向へ指向する一対の第１導線位置決め柱１０１１、１０１２が設けられている。一対の第１導線位置決め柱１０１１、１０１２は、コア支持部１０１０に支持されたドラムタイプコア２の頂面４Ａ（図１）に垂直をなす方向へ平行に延出しており、後述のようにノズル１０２０から繰出された導線７、８が掛けられて、ドラムタイプコア２に対して導線７、８が位置決めされるように構成されている。 As shown in FIG. 3, the core support portion 1010 has a pair of first conductor positioning members oriented in a direction perpendicular to the axial direction of the core portion 3 of the drum type core 2 supported by the core support portion 1010.

Therefore, when the nozzle 1020 is moved as will be described later, since one ends of the conducting wires 7 and 8 are fixed, the conducting wires 7 and 8 are respectively fed out from the nozzle 1020 as the nozzle 1020 moves.

ノズル１０２０は１本設けられており、その先端から導線７、８を繰出し可能に構成されている。ノズル１０２０は、図示せぬノズル駆動手段に支持されており、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心に垂直な方向に指向した状態を維持しながら、３次元空間内を任意の方向へ移動可能である。また、ノズル１０２０は、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心に垂直な仮想平面上において回動可能である。ノズル１０２０は導体支持部に相当する。図示せぬノズル駆動装置は図示せぬ制御装置に接続されており、相対移動手段に相当する。 One nozzle 1020 is provided, and is configured such that the conducting wires 7 and 8 can be fed from the tip.

Ultrasonic vibration is performed in a state in which a later-described peeling portion 7 h serving as a connecting portion disposed on the four metal terminals 5 and 6 is sandwiched. As a result, solid phase diffusion occurs between the peeling portion 7h of the conductors 7 and 8 and the metal terminals 5 and 6, and the conductors 7 and 8 and the metal terminals 5 and 6 are electrically joined. Yes. More specifically, the drum type core 2 is fixed to the anvil 1032, and the conducting wires 7 and 8 vibrate in synchronization with the horn 1031. When the oxide film and dirt on the bonding interface are removed at the initial stage of vibration and the oscillation time or energy set in advance is reached, the electrical connection between the conductors 7 and 8 and the metal terminals 5 and 6 is completed.

また、アンビル１０３２の近傍であってドラムタイプコア２の鍔部４−２に関して反巻芯部側には、ドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向へ指向する一対の第２導線位置決め柱１０３４、１０３５が設けられている。一対の第２導線位置決め柱１０３４、１０３５は、コア支持部１０１０に支持されたドラムタイプコア２の頂面４Ａに垂直をなす方向へ平行に延出しており、後述のようにノズル１０２０から繰出された導線７、８が掛けられて、ドラムタイプコア２に対して導線７、８が位置決めされるように構成されている。第２導線位置決め柱１０３４、１０３５は、その軸方向へ移動可能であり、導線７、８が掛けられるとき以外はドラムタイプコア２から後退（図２２の下方へ下降）し、巻芯部３への導線７、８の巻回の妨げとならないように構成されている。 In addition, a pair oriented in the direction perpendicular to the axial direction of the core part 3 of the drum type core 2 on the side opposite to the winding core part 4-2 of the drum type core 2 near the anvil 1032.

The pair of second conductor positioning columns 1034 and 1035 extends in parallel to a direction perpendicular to the top surface 4A of the drum type core 2 supported by the core support portion 1010, and is fed out from the nozzle 1020 as described later. The conducting wires 7 and 8 are hung and the conducting wires 7 and 8 are positioned with respect to the drum type core 2.

As a result, the portion of the conductive wire 7 where the later-described peeling portion 7h is formed is arranged in the vicinity of the metal terminal 6 where the peeling portion 7h is arranged. This step corresponds to the nearest position arrangement step. The metal terminal 6 corresponds to a conductor placement portion.

次に、図示せぬレーザ部を導線７の一部であってコア支持部１０１０近傍の部分に対向する位置へ移動させ、図５に示されるように、導線７の一部であってコア支持部１０１０近傍の部分、即ち金属端子６の直近位置の部分に対してレーザ部からレーザ１００２を照射する。すると絶縁被覆がレーザ１００２のエネルギーを吸収し、絶縁被覆の表面温度が上昇する。そして絶縁被覆表面が熱溶融し、絶縁被覆内部が熱伝導溶融し、絶縁被覆が蒸発し気発する。このようなレーザ照射によるメカニズムにより、当該導線７の一部に絶縁被覆が導線７の周方向の略半分剥離された半剥離部７ｇを形成する。次に、図６、図７に示されるように、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を回転軸としてコア支持部１０１０を１８０°回転させると共に、ノズル１０２０をコア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向に指向させた状態を維持しながら、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を中心としてノズル１０２０を回動させる。このようにコア支持部１０１０を回転させている最中に、図６に示されるように、クランプ１０１３に固定されている導線７の部分であってクランプ１０１３よりも反ドラムタイプコア２側の部分をカッター１０３３が切断する。 Next, the laser unit (not shown) is moved to a position that is a part of the conductive wire 7 and faces a portion in the vicinity of the core support portion 1010, and as shown in FIG. Laser 1002 is irradiated from the laser unit to a portion in the vicinity of portion 1010, that is, a portion in the immediate vicinity of metal terminal 6. Then, the insulating coating absorbs the energy of the laser 1002, and the surface temperature of the insulating coating increases. Then, the surface of the insulating coating is melted by heat, the inside of the insulating coating is thermally conductively melted, and the insulating coating is evaporated and vaporized. By such a mechanism by laser irradiation, a semi-peeled portion 7g is formed on a part of the conducting wire 7 by separating the insulating coating substantially half in the circumferential direction of the conducting wire 7. Next, as shown in FIGS. 6 and 7, the core support portion 1010 is rotated 180 ° about the axis of the core portion 3 of the drum type core 2 supported by the core support portion 1010 as a rotation axis, and the nozzle The drum type core 2 supported by the core support portion 1010 while maintaining the state in which 1020 is oriented in the direction perpendicular to the axial direction of the core portion 3 of the drum type core 2 supported by the core support portion 1010 The nozzle 1020 is rotated around the axis of the core portion 3 of the core. During the rotation of the core support portion 1010 in this way, as shown in FIG. 6, the portion of the conducting wire 7 fixed to the clamp 1013 and the portion on the side opposite to the drum type core 2 from the clamp 1013 Is cut by the cutter 1033.

次に、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向であって鍔部４の頂面に平行な方向へレーザ部を移動させ、鍔部４の頂面４Ａに垂直の方向から見てコア支持部１０１０上方を通過させ、レーザ部をコア支持部１０１０からオフセットした位置に配置する。このとき、導線７の半剥離部７ｇの絶縁被覆が残っている部分にレーザ部が対向する。次に、図８に示されるように導線７の半剥離部７ｇの絶縁被覆が残っている部分、即ち金属端子６の直近位置の部分に対してレーザ部からレーザ１００２を照射し、半剥離部７ｇにおいて残っている絶縁被覆を剥離して、導線７の周方向の全周にわたり絶縁被覆が剥離された剥離部７ｈを形成する。剥離部７ｈを形成するレーザ照射のメカニズムは、半剥離部７ｇを形成する際のレーザ照射によるメカニズムと同様である。半剥離部７ｇを形成する工程及び剥離部７ｈを形成する工程は剥離工程に相当する。 Next, the laser part is moved in a direction perpendicular to the axial center direction of the core part 3 of the drum type core 2 supported by the core support part 1010 and parallel to the top surface of the collar part 4. When viewed from the direction perpendicular to the top surface 4 </ b> A of the part 4, the upper part of the core support part 1010 is passed, and the laser part is arranged at a position offset from the core support part 1010. At this time, the laser part faces the part where the insulation coating of the semi-separated part 7g of the conductive wire 7 remains. Next, as shown in FIG. 8, a laser 1002 is irradiated from the laser unit to a portion where the insulation coating of the semi-peeled portion 7g of the conductive wire 7 remains, that is, a portion nearest to the metal terminal 6, and the semi-peeled portion The remaining insulation coating is peeled off at 7 g to form a peeling portion 7 h where the insulation coating is peeled off over the entire circumference in the circumferential direction of the conductor 7. The mechanism of laser irradiation for forming the peeling portion 7h is the same as the mechanism by laser irradiation when forming the semi-peeling portion 7g. The process of forming the semi-peeling part 7g and the process of forming the peeling part 7h correspond to a peeling process.

次に、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を回転軸として、図６、図７において回転させた方向と反対の方向へコア支持部１０１０を１８０°回転させて原点位置とすると共に、ノズル１０２０をコア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向に指向させた状態を維持しながら、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を中心として図６、図７において回動させた方向と反対の方向へノズル１０２０を回動させ、図９に示される状態とする。このとき、剥離部７ｈと金属端子６との相対的な位置関係は変わっておらず、実質的には次に行われる導体配置部配置工程が剥離工程の直後に行われる。 Next, with the axis of the core 3 of the drum type core 2 supported by the core support 1010 as the rotation axis, the core support 1010 is rotated 180 ° in the direction opposite to the direction rotated in FIGS. Rotating to the origin position and maintaining the state in which the nozzle 1020 is oriented in a direction perpendicular to the axial direction of the core 3 of the drum type core 2 supported by the core support 1010, while supporting the core The nozzle 1020 is rotated in the direction opposite to the direction rotated in FIGS. 6 and 7 around the axis of the core 3 of the drum type core 2 supported by the portion 1010, and the state shown in FIG. And At this time, the relative positional relationship between the peeling portion 7h and the metal terminal 6 is not changed, and the conductor placement portion placement step to be performed next is performed immediately after the peeling step.

次に、図１０に示されるように、ノズル１０２０を移動させて導線７を第１導線位置決め柱１０１１に掛け、鍔部４の頂面に垂直の方向から見てノズル１０２０の先端を鍔部４の頂面４Ａ上に位置する金属端子６の部分を通過させ傾斜面９上方を通過させる。そしてノズル１０２０の先端を図１０の鉛直下方へ移動させ、ノズル１０２０の先端を図１０の上下方向において巻芯部３の上面と略同じ位置に配置させ、鍔部４の頂面４Ａに垂直の方向から見て巻芯部３からオフセットした位置とする。このことにより剥離部７ｈは鍔部４の金属端子６上に配置される。この工程は導体配置部配置工程に相当する。 Next, as shown in FIG. 10, the nozzle 1020 is moved so that the conducting wire 7 is hung on the first conducting wire positioning column 1011, and the tip of the nozzle 1020 is seen from the direction perpendicular to the top surface of the flange 4. The portion of the metal terminal 6 located on the top surface 4A is passed through and above the inclined surface 9 is passed. Then, the tip of the nozzle 1020 is moved vertically downward in FIG. 10, the tip of the nozzle 1020 is disposed at substantially the same position as the upper surface of the core portion 3 in the vertical direction in FIG. 10, and is perpendicular to the top surface 4A of the flange portion 4. The position is offset from the core portion 3 when viewed from the direction. Accordingly, the peeling portion 7 h is disposed on the metal terminal 6 of the flange portion 4. This step corresponds to a conductor placement portion placement step.

次に、図１１乃至図１５に示されるように、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を回転軸としてドラムタイプコア２とコア支持部１０１０とを回転させながら、ノズル１０２０をドラムタイプコア２の巻芯部３の軸方向へ移動させて、巻芯部３全体にわたって導線７を巻回する。そしてドラムタイプコア２とコア支持部１０１０とが原点位置から１８０°回転した位置となったときに回転を停止させる。 Next, as shown in FIGS. 11 to 15, the drum type core 2 and the core support portion 1010 are rotated about the axis of the core portion 3 of the drum type core 2 supported by the core support portion 1010 as a rotation axis. Then, the nozzle 1020 is moved in the axial direction of the core part 3 of the drum type core 2 to wind the conductor 7 over the entire core part 3. Then, the rotation is stopped when the drum type core 2 and the core support portion 1010 are rotated 180 degrees from the origin position.

次に、図１６に示されるように、ノズル１０２０の先端を回動軸としてノズル１０２０を９０°回動させ、ノズル１０２０内の導線７とノズル１０２０から繰出された導線７とが一直線状となるようにする。そして、ノズル１０２０をドラムタイプコア２から離間させる。このことにより、剥離部７ｈが形成される導線７の部分が、当該剥離部７ｈが配置される金属端子５の近傍位置に配置される。この工程は直近位置配置工程に相当する。また、金属端子５は導体配置部に相当する。このとき、ノズル１０２０内の導線７とノズル１０２０から繰出された導線７とが一直線状となっているため、ノズル１０２０をドラムタイプコア２から離間させる際に導線７の絶縁被覆が損傷したり導線７中の銅線自体が損傷したりすることを防止することができる。 Next, as shown in FIG. 16, the nozzle 1020 is rotated 90 ° about the tip of the nozzle 1020 as a rotation axis, and the conducting wire 7 in the nozzle 1020 and the conducting wire 7 fed out from the nozzle 1020 are in a straight line. Like that. Then, the nozzle 1020 is separated from the drum type core 2. Thereby, the part of the conducting wire 7 where the peeling part 7h is formed is arranged in the vicinity of the metal terminal 5 where the peeling part 7h is arranged. This step corresponds to the nearest position arrangement step. The metal terminal 5 corresponds to a conductor placement portion. At this time, since the conducting wire 7 in the nozzle 1020 and the conducting wire 7 drawn out from the nozzle 1020 are in a straight line, the insulation coating of the conducting wire 7 is damaged or separated when the nozzle 1020 is separated from the drum type core 2. 7 can be prevented from being damaged.

次に、レーザ部を導線７の一部であってドラムタイプコア２近傍の部分に対向する位置へ移動させ、図１８に示されるように、導線７の一部であってドラムタイプコア２の金属端子５の直近位置の部分に対してレーザ部からレーザ１００２を照射し、当該導線７の一部に絶縁被覆が導線７の周方向の略半分剥離された半剥離部７ｇを形成する。 Next, the laser part is moved to a position that is a part of the conductive wire 7 and faces a portion in the vicinity of the drum type core 2, and as shown in FIG. A laser part 100g is irradiated from the laser part to the part at the nearest position of the metal terminal 5 to form a semi-peeled part 7g in which a part of the conducting wire 7 has an insulating coating peeled substantially half in the circumferential direction of the conducting wire 7.

次に、更に、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を回転軸としてコア支持部１０１０を１８０°回転させると共に、ノズル１０２０をコア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向に指向させた状態を維持しながら、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心を中心としてノズル１０２０を回動させて、図１９に示される状態とする。 Next, the core support portion 1010 is rotated 180 ° about the axis of the core portion 3 of the drum type core 2 supported by the core support portion 1010 as a rotation axis, and the nozzle 1020 is supported by the core support portion 1010. The axis of the core part 3 of the drum type core 2 supported by the core support part 1010 is maintained while maintaining the state oriented in the direction perpendicular to the axis direction of the core part 3 of the drum type core 2. The nozzle 1020 is rotated about the center to obtain the state shown in FIG.

次に、コア支持部１０１０に支持されたドラムタイプコア２の巻芯部３の軸心方向に垂直をなす方向であって鍔部４の頂面に平行な方向へレーザ部を移動させ、鍔部４の頂面に垂直の方向から見てドラムタイプコア２上方を通過させ、レーザ部をドラムタイプコア２からオフセットした位置に配置する。このとき、導線７の半剥離部７ｇの絶縁被覆が残っている部分にレーザ部が対向する。次に、図２０に示されるように導線７の半剥離部７ｇの絶縁被覆が残っている部分、即ち金属端子５の直近位置の部分に対してレーザ部からレーザ１００２を照射し、半剥離部７ｇにおいて残っている絶縁被覆を剥離して、導線７の周方向の全周にわたり絶縁被覆が剥離された剥離部７ｈを形成する。 Next, the laser part is moved in a direction perpendicular to the axial center direction of the core part 3 of the drum type core 2 supported by the core support part 1010 and parallel to the top surface of the collar part 4. When viewed from a direction perpendicular to the top surface of the part 4, the drum type core 2 is passed above, and the laser part is arranged at a position offset from the drum type core 2. At this time, the laser part faces the part where the insulation coating of the semi-separated part 7g of the conductive wire 7 remains. Next, as shown in FIG. 20, the laser 1002 is irradiated from the laser unit to the part where the insulation coating of the semi-separated part 7g of the conductive wire 7 remains, that is, the part immediately adjacent to the metal terminal 5, and the semi-separated part The remaining insulation coating is peeled off at 7 g to form a peeling portion 7 h where the insulation coating is peeled off over the entire circumference in the circumferential direction of the conductor 7.

次に、図２１に示されるように、アンビル１０３２をドラムタイプコア２に接近させてゆき、アンビル１０３２の上面をドラムタイプコア２の一対の鍔部４の底面４Ｂに当接させる。また、第２導線位置決め柱１０３４、１０３５をその軸方向へ移動させ、アンビル１０３２の近傍へ移動させる。このとき、剥離部７ｈと金属端子５との相対的に位置関係は変わっておらず、実質的には次に行われる導体配置部配置工程が剥離工程の直後に行われる。そして、ノズル１０２０を移動させて導線７を第２導線位置決め柱１０３４に掛けることにより、導線７の剥離部７ｈを鍔部４の金属端子５上に配置させる。この工程は導体配置部配置工程に相当する。 Next, as shown in FIG. 21, the anvil 1032 is moved closer to the drum type core 2, and the upper surface of the anvil 1032 is brought into contact with the bottom surfaces 4 </ b> B of the pair of flange portions 4 of the drum type core 2. Further, the second conducting wire positioning columns 1034 and 1035 are moved in the axial direction thereof and are moved to the vicinity of the anvil 1032. At this time, the relative positional relationship between the peeling portion 7h and the metal terminal 5 is not changed, and the conductor placement portion placement step to be performed next is performed immediately after the peeling step. And the peeling part 7h of the conducting wire 7 is arrange | positioned on the metal terminal 5 of the collar part 4 by moving the nozzle 1020 and hanging the conducting wire 7 on the 2nd conducting wire positioning column 1034. This step corresponds to a conductor placement portion placement step.

次に、ホーン１０３１の最下端面を、導線７の剥離部７ｈが配置された金属端子６、５上にそれぞれ順に当接させて、ホーン１０３１とアンビル１０３２とで、ドラムタイプコア２の鍔部４−１と鍔部４−２の金属端子６、５上に配置された継線部となる剥離部７ｈとを挟持し超音波振動させる。このことにより導線７の剥離部７ｈと金属端子５、６との間にそれぞれ固相拡散が起こり、導線７と金属端子５、６とが電気的に接合される。 Next, the lowermost end surface of the horn 1031 is brought into contact with the metal terminals 6 and 5 on which the peeling portions 7h of the conductive wires 7 are arranged in order, and the horn 1031 and the anvil 1032 are used to form a flange portion of the drum type core 2. 4-1 and the peeling part 7h used as the connection part arrange | positioned on the metal terminals 6 and 5 of the collar part 4-2 are clamped, and it ultrasonically vibrates. As a result, solid phase diffusion occurs between the peeled portion 7 h of the conductive wire 7 and the metal terminals 5 and 6, respectively, and the conductive wire 7 and the metal terminals 5 and 6 are electrically joined.

次に、カッター１０３３をドラムタイプコア２の鍔部４−１、４−２近傍の位置へ順に移動させてゆき、鍔部４−１、４−２の金属端子６、５近傍の位置であって導線７の一端部及び他端部となる箇所の近傍位置をそれぞれ切断する。以上が１本目の導線７をドラムタイプコア２の巻芯部３に対して巻回し、金属端子５、６に継線する工程である。 Next, the cutter 1033 is sequentially moved to positions near the flanges 4-1 and 4-2 of the drum type core 2, and the positions near the metal terminals 6 and 5 of the flanges 4-1 and 4-2. Then, the positions near the one end and the other end of the conducting wire 7 are cut. The above is the step of winding the first conductor 7 around the core portion 3 of the drum type core 2 and connecting it to the metal terminals 5 and 6.

そして、次に２本目の導線８を１本目の導線７と同様にして、１本目の導線７が巻回されたドラムタイプコア２の巻芯部３上に巻回し、鍔部４−１の金属端子５と鍔部４−２の金属端子６とに継線する。２本目の導線８をドラムタイプコア２の巻芯部３に対して巻回し、金属端子５、６に継線する工程では、第１導線位置決め柱１０１１、第２導線位置決め柱１０３４に代えて第１導線位置決め柱１０１２、第２導線位置決め柱１０３５が用いられる。そして、導線８の剥離部が鍔部４−１の金属端子５に配置された後に、巻芯部３に導線８が巻回され、その後に、導線８の剥離部が鍔部４−１の金属端子５に配置され、導線８の剥離部が鍔部４−１の金属端子５、鍔部４−２の金属端子６に継線される。これら以外については、１本目の導線７をドラムタイプコア２に対して巻回し、金属端子５、６に継線する工程と同様であるため、説明を省略する。以上の工程を経てコイル部品１が製造される。 Then, the second conductor 8 is wound on the core 3 of the drum type core 2 around which the first conductor 7 is wound in the same manner as the first conductor 7, It connects to the metal terminal 5 and the metal terminal 6 of the collar part 4-2. In the step of winding the second conductive wire 8 around the core portion 3 of the drum type core 2 and connecting it to the metal terminals 5 and 6, the first conductive wire positioning column 1011 and the second conductive wire positioning column 1034 are replaced with the first conductive wire positioning column 1011. A first conducting wire positioning column 1012 and a second conducting wire positioning column 1035 are used. And after the peeling part of the conducting wire 8 is arrange | positioned at the metal terminal 5 of the collar part 4-1, the conducting wire 8 is wound around the winding core part 3, and the peeling part of the conducting wire 8 is after that of the collar part 4-1. It arrange | positions at the metal terminal 5, and the peeling part of the conducting wire 8 is connected to the metal terminal 5 of the collar part 4-1, and the metal terminal 6 of the collar part 4-2. Except for these, the first conductor 7 is wound around the drum type core 2 and is connected to the metal terminals 5 and 6, and thus the description thereof is omitted. The coil component 1 is manufactured through the above steps.

上述のようにコイル部品の製造方法は、ドラムタイプコア２の金属端子５、６の直近位置に導線７、８の一部を配置させる直近位置配置工程と、金属端子５、６の直近位置に配置された導線７、８の一部の絶縁被覆を剥離して剥離部７ｈを形成する剥離工程と、剥離工程の直後に導線７、８の剥離部７ｈを金属端子５、６に配置させる導体配置部配置工程とを有し、また、コイル部品の製造装置１００１の図示せぬ制御装置は、ドラムタイプコア２の金属端子５、６の直近位置に導線７、８の一部を配置させるように図示せぬノズル駆動装置、図示せぬレーザ駆動装置を制御し、導線７、８の一部を金属端子５、６の直近位置に配置させているときに導線７、８の一部の絶縁被覆を剥離して剥離部７ｈを形成するようにレーザ部を制御し、導線７、８の一部の絶縁被覆を剥離した直後に剥離部７ｈをドラムタイプコア２の金属端子５、６に配置させるように図示せぬノズル駆動装置、図示せぬレーザ駆動装置を制御するため、金属端子５、６から物理的距離の離れた場所において予め導線の一部を剥離して剥離部を形成しておいて、他の様々な工程を経た後に導体配置部たる金属端子に剥離部を配置させる場合と比較して、導体配置部たる金属端子５、６に配置する導体７、８の一部に対して高い位置精度で絶縁被覆を剥離することができる。 As described above, the manufacturing method of the coil component includes the nearest position placement step of placing a part of the conductors 7 and 8 at the nearest position of the metal terminals 5 and 6 of the drum type core 2, and the nearest position of the metal terminals 5 and 6. A stripping process for stripping a portion of the insulation coating of the disposed conductors 7 and 8 to form a stripped portion 7h, and a conductor for placing the stripped portion 7h of the conductors 7 and 8 on the metal terminals 5 and 6 immediately after the stripping step And a control device (not shown) of the coil component manufacturing apparatus 1001 arranges a part of the conductors 7 and 8 at a position closest to the metal terminals 5 and 6 of the drum type core 2. The nozzle drive device (not shown) and the laser drive device (not shown) are controlled so that a part of the conductors 7 and 8 is insulated when a part of the conductors 7 and 8 is arranged at a position closest to the metal terminals 5 and 6. The laser part is controlled so that the coating is peeled to form the peeling part 7h. In order to control a nozzle driving device (not shown) and a laser driving device (not shown) so that the peeling portion 7 h is arranged on the metal terminals 5 and 6 of the drum type core 2 immediately after peeling off a part of the insulation coatings 7 and 8. A part of the conducting wire is peeled off in advance at a physical distance from the metal terminals 5 and 6 to form a peeled part, and after various other processes, the peeled part is formed on the metal terminal as the conductor placement part. As compared with the case where the conductor is disposed, the insulating coating can be peeled off with high positional accuracy with respect to a part of the conductors 7 and 8 disposed on the metal terminals 5 and 6 which are conductor placement portions.

本発明によるコイル部品の製造方法及びコイル部品の製造装置は、上述した実施の形態に限定されず、特許請求の範囲に記載した範囲で種々の変形や改良が可能である。例えば、剥離部７ｈが設けられる位置は、本実施の形態において剥離部７ｈが設けられた位置に限定されない。図２４、図２５に示されるように、コイル部品１０１のドラムタイプコア２の導線７、８の継線部間、例えば、導線７、８の引出部７ｃ、８ｃの途中や、巻芯部３に巻回されている導線８の巻回部７ａ、８ａに剥離部７ｈを継線部７ｂ、８ｂと不連続に形成して、当該剥離部７ｈに図示せぬ導線等を電気的に接続可能としてもよい。この場合にはドラムタイプコア２の巻芯部３は導体配置部に相当する。 Production equipment preparation and coil component of the coil component according to the present invention is not limited to the above embodiments, and various changes and modifications within the scope of the claimed. For example, the position where the peeling portion 7h is provided is not limited to the position where the peeling portion 7h is provided in the present embodiment. 24 and 25, between the connecting portions of the conductors 7 and 8 of the drum type core 2 of the coil component 101, for example, in the middle of the lead portions 7c and 8c of the conductors 7 and 8, or the core portion 3 A stripping portion 7h is formed discontinuously with the connecting portions 7b and 8b in the winding portions 7a and 8a of the conducting wire 8 wound on the wire 8, and a lead wire (not shown) can be electrically connected to the stripping portion 7h. It is good. In this case, the core part 3 of the drum type core 2 corresponds to a conductor arrangement part.

この場合コイル部品の製造方法では、本実施の形態における図５、図８に示されるレーザ剥離の工程で１本目の導線７に対して互いに不連続な位置関係となるように２箇所ずつ絶縁被覆を剥離するようにし、また、２本目の導線８に対しても同様に絶縁被覆を剥離する。また、２本目の導線８をドラムタイプコア２の巻芯部３に巻回している途中で、図５〜図９に示されるようなレーザ剥離の工程を巻芯部３の直近位置の部分に対して互いに不連続な位置関係となるように２回行って剥離部７ｈを形成すればよい。剥離部７ｈが形成された直後に剥離部７ｈを巻芯部３に配置する。このようなコイル部品１０１は、例えば中間タップを必要とするトランス等に用いられる。 In this case, in the coil component manufacturing method, insulation coating is provided at two locations so as to be discontinuous with respect to the first conductor 7 in the laser peeling process shown in FIGS. 5 and 8 in the present embodiment. The insulating coating is also peeled off from the second conductor 8 in the same manner. Further, while the second conductor 8 is being wound around the core part 3 of the drum type core 2, a laser peeling process as shown in FIGS. On the other hand, the peeling portion 7h may be formed by performing twice so as to have a discontinuous positional relationship with each other. Immediately after the peeling portion 7 h is formed, the peeling portion 7 h is disposed on the core portion 3. Such a coil component 101 is used in, for example, a transformer that requires an intermediate tap.

このようなコイル部品の製造方法により、たとえばトランス等のコイル部品の導線の中間点において電気的接続可能な接続ポイントを容易かつ高精度に形成することができる。このため、トランス等のコイル部品の設計の自由度を広げることができ、新しいコイル部品を生み出すことができる。 By such a method for manufacturing a coil component, for example, a connection point that can be electrically connected at an intermediate point of a conducting wire of a coil component such as a transformer can be easily and accurately formed. For this reason, the freedom degree of design of coil components, such as a transformer, can be expanded, and a new coil component can be produced.

また、コイル部品の製造装置１００１は、ドラムタイプコア２の巻芯部３の軸心を回転軸としてドラムタイプコア２を回転させることにより導線７、８を巻芯部３に巻回させるいわゆるスピンドル巻線装置を有していたが、これに代えてノズル１０２０をドラムタイプコア２の周囲において旋回させて巻芯部３に導線７、８を巻回させるフライヤ巻線装置を有していてもよい。 In addition, the coil component manufacturing apparatus 1001 is a so-called spindle that winds the conducting wires 7 and 8 around the core portion 3 by rotating the drum type core 2 around the axis of the core portion 3 of the drum type core 2 as a rotation axis. Although it has a winding device, instead of this, it has a flyer winding device that turns the nozzle 1020 around the drum type core 2 to wind the conductors 7 and 8 around the core portion 3. Good.

また、導線７、８の金属端子５、６への継線方法は本実施の形態による方法に限定されない。例えば、熱圧着やレーザ溶接によって電気的に接続して継線してもよい。 Moreover, the connecting method of the conducting wires 7 and 8 to the metal terminals 5 and 6 is not limited to the method according to the present embodiment. For example, electrical connection may be established by thermocompression bonding or laser welding.
