Description

この発明は、コア部材のティース部に絶縁シートを装着して巻線を施す巻線装置、及びコイルの巻線方法に関するものである。   The present invention relates to a winding device that attaches an insulating sheet to a tooth portion of a core member to perform winding, and a coil winding method.

従来、固定子鉄心の軸心方向の両端に配設された一対の絶縁端板と固定子鉄心に形成されたスロット内に配設された絶縁シートとを介し、固定子鉄心の歯部に電線を集中巻線する集中巻固定子の巻線方法において、絶縁シートを、この絶縁シートの一端を一方の絶縁端板に形成された段部に押し付けて位置決めする巻線方法及び巻線装置が提案されている（例えば、特許文献１参照）。   Conventionally, electric wires are connected to the teeth of the stator core via a pair of insulating end plates disposed at both ends in the axial direction of the stator core and insulating sheets disposed in slots formed in the stator core. In a concentrated winding stator winding method, a winding method and a winding device for positioning an insulating sheet by pressing one end of the insulating sheet against a step formed on one insulating end plate are proposed. (For example, refer to Patent Document 1).

次に、絶縁シート押圧板１１ａ、１１ｂをＸ−方向に、絶縁シート押圧板１１ａ、１１ｂが、それぞれ、絶縁シート４の外周側絶縁部４ｏｕｔを分割コア５のヨーク部５ｙの周方向側面５ｙｓに押し当てるまで移動させる。これにより、外周側絶縁部４ｏｕｔを分割コア５に固定する（ステップＳ００７：第二絶縁シート固定工程）。FIG. 12 is an enlarged perspective view of a main part of the winding device 100 after the second insulating sheet fixing step.
Next, the insulating sheet pressing plates 11a and 11b are arranged in the X-direction, and the insulating sheet pressing plates 11a and 11b are arranged on the outer peripheral side insulating portion 4out of the insulating sheet 4 on the circumferential side surface 5ys of the yoke portion 5y of the split core 5, respectively. Move until pressed. Thereby, the outer peripheral side insulating part 4out is fixed to the split core 5 (step S007: second insulating sheet fixing step).

次に、フライヤアーム２１を、回転機構２４により、図１２の矢印Ｒ方向に回転させて、分割コア５のティース部５ｔに電線７を巻回してコイルを形成する（ステップＳ００８：巻線工程）。このとき、プッシャ２２の本体と、シート固定部２２ｋとの間には、ベアリング２２ｂを備えるので、シート固定部２２ｋがフライヤアーム２１と共に回転することはない。FIG. 13 is an enlarged perspective view of a main part of the winding device 100 in the winding process.
Next, the flyer arm 21 is rotated in the direction of arrow R in FIG. 12 by the rotation mechanism 24, and the electric wire 7 is wound around the tooth portion 5t of the split core 5 to form a coil (step S008: winding process). . At this time, since the bearing 22b is provided between the main body of the pusher 22 and the seat fixing portion 22k, the seat fixing portion 22k does not rotate together with the flyer arm 21.

図１４は、最終退避工程にある巻線装置１００の要部拡大斜視図である。
巻線工程を終了したら、絶縁シート押圧板１１ａ、１１ｂを僅かにＸ＋方向に移動させた後、Ｚ−方向に移動させ、プッシャ２２を元の位置に退避させて分割コア５に対するコイルの巻線を終了する（ステップＳ００９：最終退避工程）。このとき、折りたたまれていた絶縁シート４の内周側絶縁部４ｉｎは、自然に開いてもとの形状に復帰する。FIG. 14 is an enlarged perspective view of a main part of the winding device 100 in the final retracting process.
When the winding process is completed, the insulating sheet pressing plates 11a and 11b are moved slightly in the X + direction, then moved in the Z− direction, and the pusher 22 is retracted to the original position to wind the coil around the split core 5. Is finished (step S009: final saving step). At this time, the inner peripheral side insulating portion 4in of the folded insulating sheet 4 returns to its original shape even when it is naturally opened.

本発明の実施の形態１に係る巻線装置、及びコイルの巻線方法によれば、絶縁シート４の外周側絶縁部４ｏｕｔと内周側絶縁部４ｉｎを分割コア５に確実に固定して巻線することにより、絶縁シート４のたるみ、歪み、皺を抑制できるためコイルの整列性、占積率を向上できる。また、コイル巻回中にフライヤアーム２１から供給される電線７に絶縁シート４を巻き込むことがないのでコイルの巻線不良率を大幅に低減することができる。   According to the winding device and the coil winding method according to Embodiment 1 of the present invention, the outer peripheral side insulating portion 4out and the inner peripheral side insulating portion 4in of the insulating sheet 4 are securely fixed to the split core 5 and wound. Since the sagging, distortion, and wrinkle of the insulating sheet 4 can be suppressed by performing the wiring, the coil alignment and space factor can be improved. Further, since the insulating sheet 4 is not wound around the electric wire 7 supplied from the flyer arm 21 during coil winding, the coil winding defect rate can be greatly reduced.

実施の形態２．
以下、この発明の実施の形態２に係る巻線装置、及びコイル巻線方法を、実施の形態１と異なる部分を中心に説明する。
図１５は、本実施の形態に係る巻線装置２００の要部拡大上面図である。
絶縁シート押圧板２１１ａ、２１１ｂと、コア固定部３０と、プッシャ２２のシート固定部２２ｋの要部を描いている。Embodiment 2. FIG.
Hereinafter, the winding device and the coil winding method according to the second embodiment of the present invention will be described with a focus on differences from the first embodiment.
FIG. 15 is an enlarged top view of a main part of the winding apparatus 200 according to the present embodiment.
The main parts of the insulating sheet pressing plates 211a and 211b, the core fixing part 30, and the sheet fixing part 22k of the pusher 22 are depicted.

巻線装置２００と、実施の形態１の巻線装置１００との異なる部分は、絶縁シート押圧板２１１ａ、２１１ｂの形状である。図に示すように、絶縁シート押圧板２１１ａ、２１１ｂの分割コア５側の先端Ｓａ、Ｓｂは、分割コア５の周方向側面５ｙｓに沿うように構成されている。これにより、絶縁シート４を分割コア５の周方向側面５ｙｓに密着するように確実に固定することができるので、絶縁シート４に生じる、たるみ、歪み、皺を高度に抑制できる。 A different part between the winding device 200 and the winding device 100 of the first embodiment is the shape of the insulating sheet pressing plates 211a and 211b. As shown in the drawing, the tips Sa and Sb of the insulating sheet pressing plates 211a and 211b on the split core 5 side are configured to be along the circumferential side surface 5ys of the split core 5. Thereby, since the insulating sheet 4 can be reliably fixed so as to be in close contact with the circumferential side surface 5ys of the split core 5, sagging, distortion, and wrinkles generated in the insulating sheet 4 can be highly suppressed.

尚、本発明は、その発明の範囲内において、各実施の形態を自由に組み合わせたり、各実施の形態を適宜、変形、省略することが可能である。   It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
