【発明の属する技術分野】
本発明は、超小型モータのための一体化ボビンおよびその製造方法に関し、特に、ボビン巻線及びその後工程において自動化を可能とした超小型一体化ボビンに関する。
【0002】
【従来の技術】
図6は従来の分割ボビンを分解して示す斜視図である。
図において、31は内コア、32は内ボビン、33は空芯巻コイル、34は外ボビンである。内コア31の突起部に内ボビン32を挿入し、次に、事前に1本づつ手作業で予備半田した空芯巻コイル33を挿入し、最後に外ボビン34をかぶせる。
その後、図7に横断面図で示す如く、外ボビン34が外れないように輪ゴム41で固定する。そして、外コア36を焼きばめし、輪ゴム41を切断する。
その後、空芯コイル33の予備半田部をピンセットでキバン37に一本づつ合計18本を挿入後、手半田をしてステータクミをしていた。
【0003】
また、本出願人の出願に係るコイル端末固定方法として一体化ボビンを使用したものもある(例えば、特許文献1参照。)。
【0004】
【特許文献1】
特開平8−47194号公報
【0005】
これは、部品点数を少なくすることができるとともに組み立て工数を低減できるようにするもので、そのコイル端末固定方法は、ボビンに巻回したコイルのコイル端末部をボビンのフランジ部に固定したプリント基板の導体部に接続するためのもので、その特徴は、ボビンのフランジ部の端部にコイルを固定する固定溝と固定溝の先端を横切る逃げ溝とを設け、プリント基板の周辺に開口する切欠き溝と切欠き溝の周囲を覆う導体部とを設け、コイル端末部の根元を固定溝に固定してコイル端末部を逃げ溝の上を跨ぐように配置し、プリント基板をフランジ部の端面に取り付けてコイル端末部を切欠き溝に挿入・固定し、切欠き溝の周辺の導体部とコイル端末部とを半田付けするものである。
【0006】
【発明が解決しようとする課題】
以上のように、ここで扱う対象は超小型モータであり、したがってボビンの内側にコイルカラゲを行なうピンを打つスペースが無いため、従来装置では一体ボビン化ができず、内・外2分割のボビン32,34となっている。
また、巻線は事前に融着コイルを使った空芯コイル33を用意する必要がある。
さらに空芯コイル33のため、コイルの予備半田部の固定ができずコイルの予備半田及びキバン半田工程の自動化が出来ないという問題があった。
また、特許文献1記載の固定方法には、フランジ部の端部に固定溝と固定溝の先端を横切る逃げ溝とを設ける工程が必要となり、しかもこの部分での半田づけを確実に行うことが困難であった。
本発明はこれらの課題を解決するもので、一体化ボビンの上に巻線機で巻回でき、コイルの予備半田部の固定およびコイルの予備半田及びキバン半田工程の自動化が出来、固定溝や逃げ溝の設置工程が要らない半田づけの確実に行える一体化ボビンおよびその製造方法を提供することにある。
【0007】
【課題を解決するための手段】
上記問題を解決するため、請求項1記載の一体化ボビンの発明は、モータのコアに設けるためのボビンであって、内ボビンと外ボビンと該内ボビンおよび該外ボビンとを連結する連結部とから成る一体化ボビンにおいて、コイル巻始め用のコイルカラゲ部を前記内コアの内側に張り出した状態で設けたことを特徴とする。
請求項2記載の発明は、請求項1記載の一体化ボビンにおいて、ボビン材料に耐熱性の高い液晶ポリマを使用することを特徴とする。
請求項3記載の発明は、請求項1又は2記載の一体化ボビンにおいて、前記コイルカラゲ部は折り取り可能となっていることを特徴とする。
請求項4記載の一体化ボビンの予備半田づけ方法の発明は、請求項1〜3のいずれか1項記載の一体化ボビンを巻線機に装着し、巻線の巻始めを前記コイルカラゲ部に絡げた後該一体化ボビンに巻線を施し、巻線後前記樹脂製コイルカラゲ部と前記コイルの間に予備半田を可能とするスペースを設け、半田バスに前記一体化ボビンの予備半田部を浸し、予備半田づけを行なうことを特徴とする。
請求項5記載のステータの製造方法の発明は、請求項4記載の方法により予備半田づけされた一体化ボビンを内コアに挿入し、外コアを焼きばめし、次にキバンを前記コイルカラゲ部に挿入し、キバン半田装置により半田を一括で行ない、前記コイルガラゲ部を切断することを特徴とするステータの製造方法。
以上の構成および方法により、コイルカラゲを行なうスペースが確保でき、ボビン材料に耐熱性の高い液晶ポリマを使用し、巻始めコイルカラゲを樹脂製のコイルカラゲ部に変更し、しかも内コアの内側に張り出した状態で設けることで、キバン半田付け工程までコイルの予備半田部を定位置に保持し、自動化を可能とし、部品及び工程の削減によりコストダウンになる。
【0008】
【発明の実施形態】
以下、本発明について、図面に基づいて詳細に説明する。
図1は本発明に係るステータの製造方法により、ステータが組み立てられる途中の状態を示す分解斜視図である。
図において、ボビンは内ボビン2と外ボビン4と内ボビン2と外ボビン4とを連結する連結部5(図2参照)とから構成され、この連結部5の上にコイル3が巻回されている。
2aおよび4aはそれぞれ本発明によって設けられたコイルカラゲ部で、コイル3の一方の端部3aと他端3bがここに絡げられる。ここではコイルカラゲ部2aが9個、コイルカラゲ部4aが9個設けてあり、合計18箇所で各コイル3の端部3a又は3bとの半田づけがなされている。
8はコイル3の端部3aおよび3bを接続するためのキバンで、各コイルカラゲ部2aの9個とコイルカラゲ部4aの9個の各位置に対応したキバンの内側と外側にそれぞれ切り欠き8aと8bとが9個づつあけられている。
そして本発明は、この9個のコイルカラゲ部2aと9個のコイルカラゲ部4aに絡げてあるコイル端子3aと3bとキバン8との一括による迅速で正確な半田付けができる方法を提供するものである。
キバン8は内コア1の側面に例えば接着にて固定される。
6は一体化ボビン(2,3,4)を収容した内コア1を内部に納める空間を備えた外コアで、内コア1と外コア6とは焼きばめで固定される。
【0009】
図2は本発明に係るボビンの斜視図で、(a)はコイル巻回前、(b)はコイル巻回後の各斜視図である。
ボビンは前述のごとく内ボビン2と外ボビン4と内ボビン2と外ボビン4とを連結する連結部5とから構成され、ボビン材料としては、半田の熱に耐える耐熱性の高い液晶ポリマが使用されている。
内ボビン2には本発明によって、樹脂製のコイルカラゲ部2aが上端で内側(内コア1側、図1参照)へ張り出した状態で設けられており、ここに巻始めのコイルを固定する。コイルガラゲ部2aは残しておくとモータ組時にロータと干渉するので、コイルガラゲ部2aは根元で切断可能にしておいて、最終工程で切断される。これによってステータクミの完成となる。
本発明によれば、一方、外ボビン4にもコイルカラゲ部4aを設けており、ここに巻終わりのコイルを固定する。
図2(b)は、以上のようにしてコイルカラゲ部2aおよび4aにコイル端部を絡げて巻回されたコイルを備えたボビンを示している。巻線後、予備半田部であるコイルカラゲ部2a,4aの予備半田を行なう。
【0010】
図3は図2(b)のコイルカラゲ部2a,4aとコイル端部3a、3bとの半田をする予備半田付けを説明する図で、(a)は半田前、(b)半田の最中をそれぞれ示す断面図である。図から判るように、樹脂製コイルカラゲ部2aとコイル3の間に予備半田を可能とするスペースを設け、半田バス10に一体化ボビン1の予備半田部であるコイルカラゲ部2a,4aを浸して、予備半田を行なう。コイルカラゲ部2a,4aの予備半田を終わった後、内コア1に外コア6を焼きばめする。
図4は焼きばめを説明する図で、(a)は内コア1側、(b)は外コア側である。焼きばめはまず外コア6を外コア用受けジグ61で支持した状態で加熱し膨張し、その後内コア1を外コア6の内部空間に挿入し、そのまま冷却することによって固定される。
次に、コイルカラゲ部2a,4aにキバン(図1参照)を挿入する。
キバンを挿入する時、コイルカラゲ部2a,4aの予備半田したコイル3とキバン8は干渉位置にあるが、コイル3がフレキシブルなためスムーズに挿入できる。
このようにして、キバン8が挿入された段階で、キバン8とコイル3との一括半田付けがキバン半田装置により18点の半田を一括で行なわれる。
【0011】
図5はコイルカラゲ部2a,4aとキバン8との本発明による一括半田付けを説明する図で、(a)は半田前、(b)半田の最中をそれぞれ示す断面図である。
図において、2は内ボビン、2aはコイルカラゲ部、3a,3bはコイル端部、4は外ボビン、4aはコイルカラゲ部、6は外コア、8はキバン、9はキバン保持具、10は半田バスである。
図1のキバン8と内コア1と外コア6を全て組み立てた状態で、コイルカラゲ部2aとコイルカラゲ部4aを下向きにしてキバン保持具9の上に載せる。
キバン保持具8には、コイルカラゲ部2aとコイルカラゲ部4aに対応した箇所(ここでは18箇所)に穴があけてあり、半田されるべき部分だけキバン保持具8から半田バス10側に突出して、半田バス10に接触できるようにしている。
図5(a)のように、キバン8を挿入したコア全体をキバン保持具9の上に載せた状態で、そのまま図5(b)のように、コイルカラゲ部2aの先端から半田バス10の中へ沈めていき、キバン8が溶融半田に漬かるまで降下させてストップする。このようにして、18箇所の半田すべき箇所が同時に半田される。
半田終了後は、コイルカラゲ部2aは折り取られ、後にモータ組時のロータとの干渉を防止する。
【0012】
【発明の効果】
以上述べた様に、本発明に係るボビンは耐熱性の高い液晶ポリマ製の一体化ボビンであり、コイル巻始め用のコイルカラゲ部を内コアの内側に張り出した状態で設け、このコイルカラゲ部は折り取り可能となっているので、巻線機によるボビン巻線が可能となり、空芯コイルに比べて、外注巻線費が2/3になり、合わせてボビン部品点数の巻線までのリードタイムの短縮ができる。
