Description

本発明は、ステータにコイルを形成する巻線機構に関し、特に回転式ノズルを備えるステータコイルの巻線機構に関する。 The present invention relates to a winding mechanism for forming a coil on a stator, and more particularly to a winding mechanism for a stator coil including a rotary nozzle.

従来より、レゾルバの励磁コイルと出力コイルとからなるステータコイルは、巻線機構によりティースに巻回されて形成されている。ステータコイルを形成するマグネットワイヤは、巻線機構の先端部から供給され、ステータの開口部に周方向等間隔に備えられているティースにそれぞれ巻回され、ステータコイルが形成されている。ステータの開口部内にティースが設けられているインナー型のステータでは、開口部内の空間が狭いため、開口部内に挿入されてマグネットワイヤを巻回する機構部は小型である必要がある。また、１つのティースにコイルを形成するのに、マグネットワイヤをティースに何度も巻回しなければならない。そのため、巻線機構と、ステータを保持しながら正逆方向に小刻みに回転させる回転台とをうまく連動させる制御が必要であった。 Conventionally, a stator coil composed of an exciting coil and an output coil of a resolver is formed by being wound around a tooth by a winding mechanism. The magnet wire forming the stator coil is supplied from the tip of the winding mechanism and wound around the openings of the stator at equal intervals in the circumferential direction to form the stator coil. In the inner type stator in which the teeth are provided in the opening of the stator, the space in the opening is narrow, so that the mechanism portion inserted into the opening and winding the magnet wire needs to be small. Also, in order to form a coil on one tooth, the magnet wire must be wound around the tooth many times. Therefore, it is necessary to control the winding mechanism and the turntable that rotates in small steps in the forward and reverse directions while holding the stator.

特許文献１に記載されている巻線機構では、先端からマグネットワイヤが引き出され、環状ステータの中心軸方向に往復動するニードルアームと、ステータを保持し、ティース１つ分の周方向の角度範囲内で小刻みに正転逆転を繰り返す回転台とを連動させて、ティースにコイルを形成するように構成されている。 In the winding mechanism described in Patent Document 1, a magnet wire is pulled out from the tip to hold a needle arm that reciprocates in the central axis direction of the annular stator and a stator, and an angular range in the circumferential direction for one tooth. It is configured to form a coil on the teeth by interlocking with a turntable that repeats forward and reverse rotation in small steps.

しかしながら、上記の巻線機構では、ニードルアームの往復動と、ステータの正逆方向の小刻みの回転との同期制御をする必要があり、制御が複雑となっていた。このような機構において、巻線時間を短縮するために巻線機構の動作を高速化すると、ニードルアームが往復動する構造のため、振動が発生していた。また、高速化するほどマグネットワイヤに係るテンションの変動量が大きくなるため、安定したテンション制御ができなかった。上記理由により、巻線機構の高速化は困難であった。 However, in the above-mentioned winding mechanism, it is necessary to synchronously control the reciprocating movement of the needle arm and the small rotation of the stator in the forward and reverse directions, which makes the control complicated. In such a mechanism, when the operation of the winding mechanism is increased in order to shorten the winding time, vibration is generated due to the structure in which the needle arm reciprocates. Further, as the speed is increased, the amount of fluctuation of the tension related to the magnet wire becomes large, so that stable tension control cannot be performed. For the above reasons, it has been difficult to increase the speed of the winding mechanism.

本発明は、上記の課題を解決するためになされたものであり、ティースにマグネットワイヤを巻回する巻回時間を短縮できる巻線機構を提供することを目的としている。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a winding mechanism capable of shortening the winding time for winding a magnet wire around a tooth.

＜導線巻回方法＞
次に、本巻線機構１００を用いて、ステータ２００にステータコイル２２２を形成する方法を説明する。まず、ステータ２００を図示しない回転台に保持し、巻線機構１００をステータ２００に対しセットする。図３は、巻線機構１００のノズル部材１０Ａが、隣り合う２つのティース２２０、２２０の間のスリット２２１に配置された状態を示している。連結軸８０の中心である第１軸Ｘ−Ｘが巻回するティース２２０の突出方向の中心軸Ｚ−Ｚと一致するように、巻線機構１００を配置する。なお、ステータ２００を固定している回転台は、ステータ２００を保持したまま、ステータ２００の開口部２０１の中心を回転中心に回転できるように構成されている。 <How to wind the wire>
Next, a method of forming the stator coil 222 on the stator 200 by using the winding mechanism 100 will be described. First, the stator 200 is held on a turntable (not shown), and the winding mechanism 100 is set with respect to the stator 200. FIG. 3 shows a state in which the nozzle member 10A of the winding mechanism 100 is arranged in the slit 221 between two adjacent teeth 220 and 220. The winding mechanism 100 is arranged so that the first axis XX, which is the center of the connecting shaft 80, coincides with the central axis ZZ in the protruding direction of the teeth 220 to be wound. The turntable that fixes the stator 200 is configured so that it can rotate around the center of the opening 201 of the stator 200 while holding the stator 200.

次に、巻線機構１００の所定経路に配線されているマグネットワイヤ１を、供給部１２Ａから引き出し、ステータ２００のティース２２０を介して、マグネットワイヤ１の端部を所定箇所に固定する。図４には、巻線機構１００を配線されているマグネットワイヤ１の経路が示されている。マグネットワイヤ１は、図示しない導線供給部材から連結軸８０まで、所定の経路を通って配線されている。図４に示されているとおり、マグネットワイヤ１は、連結軸８０の一端開口部８２、軸中空部８５、及び、他端開口部８４を通り、支持部材の他端部貫通孔４４、及び、一端部貫通孔４２を通って、ノズル部材１０Ａの経由部１４Ａ、及び、供給部１２Ａに配線されている。 Next, the magnet wire 1 wired in the predetermined path of the winding mechanism 100 is pulled out from the supply unit 12A, and the end portion of the magnet wire 1 is fixed at a predetermined position via the teeth 220 of the stator 200. FIG. 4 shows the path of the magnet wire 1 to which the winding mechanism 100 is wired. The magnet wire 1 is wired from a lead wire supply member (not shown) to the connecting shaft 80 through a predetermined path. As shown in FIG. 4, the magnet wire 1 passes through the one end opening 82, the shaft hollow portion 85, and the other end opening 84 of the connecting shaft 80, and passes through the other end through hole 44 of the support member and the other end through hole 44. It is wired to the passage portion 14A and the supply portion 12A of the nozzle member 10A through the through hole 42 at one end.

マグネットワイヤ１の端部がステータの所定箇所に固定された後、巻線機構１００によりマグネットワイヤ１がティース２２０に所定回数巻回されて、ステータコイル２２２が形成される。１つのティース２２０への巻回が完了すると、次に巻回するティースの中心軸Ｚ−Ｚが、第１軸Ｘ−Ｘと一致する位置まで、ステータ２００を固定している回転台が回転する。次に巻回するティース２２０に隣接するスリット２２１にノズル部材１０Ａが配置されて、次に巻回するティース２２０にマグネットワイヤ１の巻回を行う。なお、巻回は、同じ種類のコイルが連続して行なわれる。具体的には、１次励磁コイル、２次励磁コイル、又は、出力コイルごとに連続して巻回するように、同じ種類のステータコイル２２２が形成されるティース２２０が飛び飛びで選択されて、次の巻回を行う。同じ種類のステータコイル２２２ごとに巻回を行い、全てのティース２２０にステータコイル２２２を形成したら、作業を終了する。 After the end of the magnet wire 1 is fixed at a predetermined position on the stator, the magnet wire 1 is wound around the teeth 220 a predetermined number of times by the winding mechanism 100 to form the stator coil 222. When the winding around one tooth 220 is completed, the turntable fixing the stator 200 rotates to a position where the central axis ZZ of the tooth to be wound next coincides with the first axis XX. .. The nozzle member 10A is arranged in the slit 221 adjacent to the tooth 220 to be wound next, and the magnet wire 1 is wound around the tooth 220 to be wound next. The same type of coil is continuously wound. Specifically, the teeth 220 in which the same type of stator coil 222 is formed so as to be continuously wound for each primary exciting coil, secondary exciting coil, or output coil are selected in a discrete manner, and then next. Perform the winding. When the stator coil 222 of the same type is wound and the stator coil 222 is formed on all the teeth 220, the work is completed.

本発明の実施の形態に係る巻線機構１００は、ティース２２０に巻回されるマグネットワイヤ１を引き出し可能に保持し、回転してティース２２０にマグネットワイヤ１を巻回する供給部材１０を備えている。 The winding mechanism 100 according to the embodiment of the present invention includes a supply member 10 that holds the magnet wire 1 wound around the teeth 220 in a drawable manner and rotates to wind the magnet wire 1 around the teeth 220.

したがって、本発明によれば、ティース２２０にマグネットワイヤ１を巻回する巻回時間を短縮することができる。 Therefore, according to the present invention, the winding time for winding the magnet wire 1 around the teeth 220 can be shortened.

本発明の実施の形態に係るステータコイルの巻線機構は、環状のステータコアの内周に複数のティースが形成されているインナー型のステータコアに適用する形態について説明したが、環状のステータコアの外周に複数のティースが形成されているアウター型のステータにも適用可能である。 The winding mechanism of the stator coil according to the embodiment of the present invention has been described as being applied to an inner type stator core in which a plurality of teeth are formed on the inner circumference of the annular stator core.

また、供給部材１０の例として、先端部１１Ａに開口部である供給部１２Ａと、基端部１３Ａに開口部である経由部１４Ａと、供給部１２Ａと経由部１４Ａとを連通する中空部１５Ａと、を有するノズル部材１０Ａを示し、マグネットワイヤ１が中空部１６Ａを通って先端部１１Ａの供給部１２Ａから供給される実施例について説明した。これ以外の実施例として、供給部材１０が中空部１５Ａを有さなくても可能である。例えば、中空部１６を有さない棒状の長手部材の供給部材１０の長手方向における先端部１１等の１ケ所、先端部１１と基端部１３等の２ケ所、又は３ケ所以上の複数個所において、マグネットワイヤ１を引き出し可能に保持できるフック、又は、中心に孔を有するリングを必要数設けられた供給部材１０を備えることも可能である。 Further, as an example of the supply member 10, the hollow portion 15A communicating the supply portion 12A having an opening at the tip portion 11A, the passage portion 14A having an opening at the base end portion 13A, and the supply portion 12A and the passage portion 14A.
