Description

【０００１】
【発明の属する技術分野】
本発明は板状部品の取り付け用治具に関し、より詳細にはコンパクトディスク（ＣＤ）再生装置の光ピックアップユニットを構成するヨークに板状マグネットを取り付ける際等において使用される板状部品の取り付け用治具に関する。
【０００２】
【従来の技術】
コンパクトディスク（ＣＤ）の裏側にはピットといわれる溝部が円周方向に形成されており、ＣＤ再生装置では、ピックアップユニットに設置されたレーザ光源からのレーザ光が前記ピットに照射されたときの反射光の強度と、前記ピットが形成されていない平坦面に照射されたときの反射光の強度をデジタル信号として読み取り、これによりＣＤに記録されている音楽や映像等の情報を再生する。
【０００３】
しかし、ＣＤをターンテーブル上でＣＤ裏側のピットが左右上下に全くぶれないように回転させるのは難しい。そこで、ＣＤに形成されたピットとレーザ光の光源との距離を常に一定に保つために、光ピックアップユニットの可動部が前記ピットを追尾する機構（トラッキングサーボ機構、フォーカシングサーボ機構）が採用されている。
【０００４】
すなわち、２枚の板状マグネットの間に介装されたボビンと呼ばれる電磁石に電流を流すことにより、前記ボビンを含む光ピックアップユニットの可動部を上下左右に微動させ、これにより所定距離でレーザ光源がピットを追尾するようになっている。
【０００５】
図１３は、前記板状マグネット、及び該板状マグネットを固定するためのヨークを模式的に示した斜視図である。
【０００６】
このヨーク３１は、Ｈ形状の基板３３と、この基板３３上に略平行に立設された２枚の平板３２とから構成されており、構成材料は鉄等の磁性体である。板状マグネット３６は、縦、横が数ｍｍ、厚さが１ｍｍ程度と小さく、ネオジウム等の強力な磁石により構成されている。
【０００７】
従来、このヨーク３１に板状マグネット３６を取り付けるには、ヨーク３１の平板３２の内側に接着剤３５を塗布し、四角柱形状の磁石を切削して作製しておいた板状マグネット３６を、人手により平板３２の内側に接着していた。
【０００８】
【発明が解決しようとする課題】
しかし、板状マグネット３６の磁力は強力であるため、平板３２に取り付ける際、板状マグネット３６同士が引き合って吸着してしまい易く、取り付けが困難であるという課題があった。
【０００９】
また、板状マグネット３６は上記したように非常に小さいため取扱い難く、また、鉄製のヨーク３１に吸着され易いため、平板３２の正確な位置に接着するのが難しいという課題があった。
【００１０】
また、平板３２には、磁極の方向が一定になるように板状マグネット３６を接着しなければならないが、上記切削作業により板状マグネット３６を作製・分離した後は、極性（Ｎ、Ｓ）を判別するのが難しくなるため、磁極の方向を間違えて板状マグネット３６を貼り付け易いという課題もあった。
【００１１】
さらに、板状マグネット３６を正確に平板３２に接着する際、図１４に示したように板状マグネット３６をスライドさせながら接着させる方式も考えられるが、この方式では、平板３２に塗布した接着剤３５が下方におされ、基板３３面等の不必要な部分に付着してしまう。
【００１２】
本発明は上記課題に鑑みなされたものであり、基板上に２枚の平板が立設された金属製部品のこれら平板等に、正確かつ迅速に板状部品を固定することができる板状部品の取り付け用治具を提供することを目的としている。
【００１３】
【課題を解決するための手段及びその効果】
上記目的を達成するために本発明に係る板状部品の取り付け用治具（１）は、対向する２枚の平板が略平行に基板上に立設された金属製部品における前記両平板の内側に、１対の板状部品を固定するための板状部品の取り付け用治具であって、
前記板状部品を挿入するための挿通孔上部と、該挿通孔上部を通過した前記板状部品を前記平板に固定させるために該平板の挿脱が可能なように拡大形成された挿通孔下部とから構成された２つの挿通孔が、上面より下面に略垂直に、かつ互いに平行に形成された取り付け部材と、
把持部と、該把持部から延設され、前記取り付け部材の前記２つの挿通孔に挿入される前記２枚の板状部品を押し込むための長さの異なる２本の押し込み片と、前記把持部に内装され、長い方の押し込み片を下方に付勢する弾性体とを含んで構成された押し込み部材と
を含んで構成されると共に、
前記挿通孔上部の平面視形状が前記板状部品の上面形状と略同一であり、前記挿通孔下部の縦の長さが前記平板の縦の長さと略同一で、横の長さが前記平板の厚さと該平板に塗布する接着剤の厚さと前記板状部品の厚さの合計よりも大きく、高さが前記平板の高さと略同一であることを特徴としている。
【００１４】
上記板状部品の取り付け用治具（１）によれば、前記挿通孔上部の平面視形状が前記板状部品の上面形状と略同一であるので、前記板状部品を前記挿通孔上部に挿入した際に緩い嵌合状態となり、前記板状部品が前記挿通孔上部の中で左右前後に傾くことはない。従って、左右前後に傾くことなく真直ぐに、前記板状部品を前記挿通孔下部へ押し込むことができる。
また、前記挿通孔下部の縦の長さが前記平板の縦の長さと略同一で、高さが前記平板の高さと略同一であるので、前記板状部品の縦の長さが前記平板の縦の長さと略同一であり、高さが前記平板の高さと略同一であれば（すなわち、前記板状部品の縦の長さが前記挿通孔下部及び前記平板の縦の長さと略同一であり、高さが前記挿通孔下部及び前記平板の高さと略同一であれば）、左右前後に傾くことなく真直ぐに前記挿通孔下部にまで押し込められた前記板状部品は前記平板に吸引され、前記挿通孔下部内を前記平板側へ水平方向に平行移動して前記平板に固定される。
従って、前記取り付け部材の前記挿通孔下部を前記平板に位置合わせしておき、板状マグネットのような強磁性体からなる前記板状部品を前記取り付け部材の前記挿通孔上部より挿入し、前記押し込み部材により前記挿通孔下部にまで押し込む操作を行うと、前記挿通孔下部に移動した前記板状部品が金属製の前記平板に磁気的に吸引され、接着剤等が塗布された前記平板に前記板状部品を固定することができる。
【００１５】
このとき、前記押し込み部材が有する前記２本の押し込み片の長さが異なるため、前記板状部品の前記挿通孔中でのお互いの垂直方向の位置（高さ）が異なり、前記板状部品同士の磁気的な吸引力によりお互いが動きにくくなるといった事態は生じない。また、前記押し込み部材の前記把持部には弾性体が内装され、前記長い方の押し込み片の前記把持部から突出する長さが変化するようになっているので、前記長い方の押し込み片による前記板状部品の押し込みが完了すると、前記弾性体が縮んで前記長い方の押し込み片の一部は前記把持部内に収納されて突出長さが短くなり、このため短い方の前記押し込み片により前記板状部品を前記挿通孔下部にまで押し込んで、前記平板に固定することができる。
また、前記把持部に前記弾性体が内装され、前記長い方の押し込み片の前記把持部から突出する長さが変化するようになっているが、前記弾性体は前記長い方の押し込み片を下方に付勢するものであるので、前記長い方の押し込み片による前記板状部品の押し込みが完了するまでは、前記長い方の押し込み片の前記把持部から突出する長さは変化しない。従って、前記板状部品の前記挿通孔中でのお互いの垂直方向の位置（高さ）が同じとならないようにすることができる。
【００１６】
このように、前記取り付け部材の前記金属製部品に位置合わせしておき、前記板状部品を前記押し込み部材を用いて前記挿通孔下部に押し込むという簡単な操作により、前記２枚（１対）の板状部品を前記２枚の平板の内側の正確な位置に、容易かつ迅速に固定することができる。
【００１７】
また本発明に係る板状部品の取り付け用治具（２）は、上記板状部品の取り付け用治具（１）において、前記２つの挿通孔下部の外側壁面間の距離が前記２つの平板の外側対向面間の距離と略同一であることを特徴としている。
【００１８】
上記板状部品の取り付け用治具（２）によれば、前記挿通孔下部は、縦の長さが前記平板の縦の長さと略同一で、高さが前記平板の高さと略同一で、前記２つの挿通孔下部の外側壁面間の距離が前記２つの平板の外側対向面間の距離と略同一であるため、前記金属製部品の前記２枚の平板を前記挿通孔下部に挿入することにより自動的に正確に位置合わせがなされ、前記平板に前記挿通孔下部がしっかりと固定される。
【００２０】
また本発明に係る板状部品の取り付け用治具（３）は、上記板状部品の取り付け用治具（１）又は（２）において、前記２本の押し込み片の長さの差が前記板状部品の高さよりも大きいことを特徴としている。
【００２１】
上記板状部品の取り付け用治具（３）によれば、前記２本の押し込み片の長さの差が前記板状部品の高さよりも大きいので、前記挿通孔に押し込まれた前記２枚の板状部品は水平方向に重なることがなく、前記挿通孔中で前記板状部品同士の磁気的な吸引力は殆ど働かず、前記２枚の板状部品を前記押し込み部材によりスムーズに移動させることができる。
【００２２】
また本発明に係る板状部品の取り付け用治具（４）は、上記板状部品の取り付け用治具（１）〜（３）において、前記取り付け部材に形成された前記２つの挿通孔の上端近傍が拡開していることを特徴としている。
【００２３】
上記板状部品の取り付け用治具（４）によれば、前記取り付け部材に形成された前記２つの挿通孔の上端近傍が拡開しているので、前記上端近傍が前記板状部品の案内部分となり、該板状部品を容易に前記挿通孔上部に挿入することができる。
【００２４】
また本発明に係る板状部品の取り付け用治具（５）は、上記板状部品の取り付け用治具（１）〜（４）において、前記取り付け部材の上面における前記２つの挿通孔の周囲に、傾斜面を有する案内部材が前記傾斜面を前記挿通孔側に向けて配置されていることを特徴としている。
【００２５】
上記板状部品の取り付け用治具（５）によれば、前記２つの挿通孔の周囲に前記案内部材が配置されているので、前記板状部品を容易に前記挿通孔上部に挿入することができる。
【００２６】
また本発明に係る板状部品の取り付け用治具（６）は、上記板状部品の取り付け用治具（１）〜（５）において、前記取り付け部材の側面から前記２つの挿通孔下部のそれぞれの横側壁面に通ずる板状部品検知用貫通孔が形成され、該板状部品検知用貫通孔に接着剤及び前記板状部品を検知するための板状部品検知手段が配設されていることを特徴としている。
【００２７】
上記板状部品の取り付け用治具（６）によれば、前記取り付け部材に前記板状部品検知用貫通孔が形成され、該板状部品検知用貫通孔に前記板状部品検知手段が配設されているので、該板状部品検知手段により前記平板に接着剤が塗布されているか否か、及び前記板状部品が接着されたか否かを容易かつ迅速に判断することができ、前記平板に接着剤が塗布されないまま前記板状部品が取り付けられるといった事態や、前記板状部品が固定されないまま前記金属製部品を前記取り付け部材より外してしまうといった事態の発生を防止することができる。
【００２８】
また本発明に係る板状部品の取り付け用治具（７）は、上記板状部品の取り付け用治具（１）〜（６）において、前記取り付け部材及び前記押し込み部材が非磁性体により構成されていることを特徴としている。
【００２９】
上記板状部品の取り付け用治具（７）によれば、前記取り付け部材及び前記押し込み部材が非磁性体により構成されているので、前記板状部品が強磁性体であっても、前記板状部材が前記取り付け部材の前記挿通孔壁面に吸着されることはなく、前記挿通孔内部で前記板状部品を前記押し込み部材により簡単に移動させることができる。
【００３０】
また本発明に係る板状部品の取り付け用治具（８）は、上記板状部品の取り付け用治具（１）〜（７）において、前記取り付け部材の底部にマグネットが埋設されていることを特徴としている。
【００３１】
上記板状部品の取り付け用治具（８）によれば、前記取り付け部材の底部に前記マグネットが埋設されているので、磁性体よりなる前記金属製部品を前記マグネットで吸着させることによりしっかりと固定することができ、前記金属製部品への挿入不足等による前記板状部品の固定不良の発生を防止することができる。
【００３２】
また本発明に係る板状部品の取り付け用治具（９）は、上記板状部品の取り付け用治具（１）〜（８）において、前記２つの挿通孔下部のそれぞれの外側壁面に通ずるエアー吸引用貫通孔が前記取り付け部材に形成されていることを特徴としている。
【００３３】
上記板状部品の取り付け用治具（９）によれば、前記取り付け部材の前記挿通孔下部に通ずる前記エアー吸引用貫通孔が形成されているので、前記エアー吸引用貫通孔よりエアーを吸引することにより、前記板状部品が強磁性体でない場合でも、前記板状部品を容易に前記平板に固定することができる。
【００３４】
また本発明に係る板状部品の取り付け用治具（１０）は、上記板状部品の取り付け用治具（１）〜（９）において、前記把持部の前記押し込み片が延設された面と反対側の面に、弾性体が巻装された軸部が固定され、該軸部に衝撃吸収部材本体が前記弾性体を介して上下方向に摺動可能に支持され、前記弾性体、前記軸部、及び前記衝撃吸収部材本体を含んで衝撃吸収部材が構成されていることを特徴としている。
【００３５】
上記板状部品の取り付け用治具（１０）によれば、前記把持部に前記弾性体が巻装された軸部を介して前記衝撃吸収部材本体が支持されているので、前記押し込み片により前記板状部品を前記挿通孔下部の下端にまで押し下げた際の、衝撃等による前記板状部品の破損等や、前記金属製部品の損傷等を防止することができる。
【００３６】
また本発明に係る板状部品の取り付け用治具（１１）は、上記板状部品の取り付け用治具（１）〜（１０）において、前記押し込み部材が、弾性体が巻装された２本の軸部を介して前記取り付け部材に上下動可能に支持されていることを特徴としている。
【００３７】
上記板状部品の取り付け用治具（１１）によれば、前記押し込み部材が２本の軸部を介して前記取り付け部材に上下動可能に支持されているので、前記板状部品を前記挿通孔に挿入した後、前記押し込み部材を押し下げる操作を行うのみで、前記板状部品をきわめて容易に前記平板に固定することができる。
【００３８】
また本発明に係る板状部品の取り付け用治具（１２）は、上記板状部品の取り付け用治具（１）〜（１１）において、前記取り付け部材の前記挿通孔に前記板状部品を自動的に供給するための板状部品供給手段が、前記取り付け部材上面に接して配設されると共に、前記板状部品供給手段を構成する板状部品保持容器の上方に、前記押し込み部材と、該押し込み部材を自動的に上下動させるための押し込み部材移動手段とが配設されていることを特徴としている。
【００３９】
また本発明に係る板状部品の取り付け用治具（１３）は、上記板状部品の取り付け用治具（１２）において、前記板状部品供給手段が、前記板状部品を整列状態で保持する前記板状部品保持容器と、該板状部品保持容器に保持された前記板状部品を順次挿通孔直上にまで移動させる板状部品移動手段とからなり、
前記押し込み部材移動手段が、前記取り付け部材に立設されて前記押し込み部材が上下動可能に挿通された２本のガイド棒と、これらガイド棒の上端に固定された板状部材と、該板状部材上に設置され、軸部の先端が前記押し込み部材に固定され、前記軸部の往復運動により前記押し込み部材を上下方向に移動させるピストン機構又はモータ駆動機構とからなることを特徴としている。
【００４０】

【００４１】
また本発明に係る板状部品の取り付け用治具（１４）は、上記板状部品の取り付け用治具（１）〜（１３）において、前記板状部品が板状マグネットであり、金属製部品がディスク再生装置の光ピックアップを構成するヨークであることを特徴としている。

上記板状部品の取り付け用治具（１５）によれば、前記取り付け部材に前記センサ配設用貫通孔が形成され、該センサ配設用貫通孔に前記磁極判定手段が配設されているので、前記挿通孔に前記板状マグネットが挿入されたか否か、及び挿入された前記板状マグネットの磁極の向きを容易に判定することができ、前記板状マグネットが前記平板に固定されないまま前記金属製部品が前記取り付け部材より外されるといった事態や、前記板状マグネットが誤った磁極の向きで前記平板に固定されるといった事態の発生を防止することができる。
【００４５】
【発明の実施の形態】
以下、本発明に係る板状部品の取り付け用治具の実施の形態を図面に基づいて説明する。
【００４６】
実施の形態に係る板状部品の取り付け用治具は、「従来の技術」の欄において説明したディスク再生装置の光ピックアップを構成するヨーク（金属製部品）に立設された平板の内側に板状マグネット（板状部品）を固定する場合に、効果的に使用することができるが、前記板状部品の取り付け用治具の用途は上記した用途に限定されるものではなく、対向する２枚の平板が略平行に基板上に立設された金属製部品であれば、他の部材であっても使用することができる。
【００４７】
図１は、実施の形態（１）に係る板状部品の取り付け用治具、及び板状部品を取り付けるヨーク（金属製部品）を模式的に示した斜視図であり、図２（ａ）及び（ｂ）は前記板状部品の取り付け用治具を使用して板状マグネット（板状部品）をヨーク（金属製部品）に取り付ける際の途中の状態をそれぞれ示した断面図である。
【００４８】
実施の形態（１）に係る板状部品の取り付け用治具１０は、取り付け部材１１と押し込み部材２１とから構成されている。
【００４９】
取り付け部材１１は略直方体形状であり、中央部の薄い中板１２とその左右に配設された本体１３とから構成されており、中板１２を挟んで２つの挿通孔１４（１４ａ、１４ｂ）が上面より下面に略垂直に、かつ互いに平行に形成されており、これら挿通孔１４ａ、１４ｂは板状マグネット３６を挿入するための挿通孔上部１５ａ、１５ｂと、挿通孔上部１５ａ、１５ｂを通過した板状マグネット３６をヨーク３１の平板３２の内側に固定させるため平板３２の挿脱が可能なように拡大形成された直方体形状の挿通孔下部１６ａ、１６ｂとから構成されている。
【００５０】
また、板状マグネット３６が挿通孔上部１５ａ、１５ｂに挿入された際、簡単に挿通孔下部１６ａ、１６ｂまで落ちたり、挿入された状態で左右前後に傾かないように、挿通孔上部１５ａ、１５ｂの形状は平面視において板状マグネット３６の上面と略同一の形状となっている。また、挿通孔下部１６ａ、１６ｂは、縦の長さが平板３２の縦の長さと略同一で、高さが平板３２の高さと略同一であり、２つの挿通孔下部１６ａ、１６ｂの外側壁面１６０ａ、１６０ｂ間の距離が２つの平板３２の外側対向面間の距離と略同一であるように設定されており、図２に示したように２つの平板３２が挿通孔下部１６ａ、１６ｂに嵌合され、自動的に正確に位置合わせがなされる。また、挿通孔下部１６ａ、１６ｂに押し込まれた板状マグネット３６が接着剤３５を切断していかないよう、挿通孔下部１６ａ、１６ｂの横の長さは平板３２の厚さと平板３２に塗布する接着剤の厚さと板状マグネット３６の厚さの合計よりも大きく設定されている。
【００５１】
押し込み部材２１は、把持部２４と、把持部２４から延設され、取り付け部材１１の２つの挿通孔１４に挿入された２枚の板状マグネット３６を押し込むための長さの異なる２本の押し込み片２２、２３と、把持部２４に内装され、長い方の押し込み片２４を下方に付勢する弾性体であるコイルバネ２５とを含んで構成されている。押し込み片２２、２３の長さを異なったものにしているのは、板状マグネット３６が互いに磁気的に引き合うので、挿通孔１４ａ、１４ｂに板状マグネット３６を挿入した際、２枚の板状マグネット３６が挿通孔上部１５ａ、１５ｂにおいて水平方向に重ならないようにするためである。２枚の板状マグネット３６が水平方向に完全に重ならないようにするためには、２つの押し込み片２２、２３の長さの差は、板状マグネット３６の高さよりも大きい方が好ましい。
【００５２】
これら取り付け部材１１や押し込み部材２１は、いずれもアルミニウム、銅、あるいはプラスチック等の非磁性体により構成されているため、板状マグネット３６が吸着することはない。また、挿通孔１４ａ、１４ｂは、本体１３に溝加工を施すことにより形成される。
【００５３】
このように構成された板状部品の取り付け用治具１０を用いて、板状マグネット３６をヨーク３１に立設された平板３２の内側に固定するには、まず、平板３２を取り付け部材１１の挿通孔下部１６ａ、１６ｂに嵌合させて位置合わせをしておき、板状マグネット３６を右側の挿通孔上部１５ａに挿入し、押し込み片２２を用いて挿通孔上部１５ａの内部に押し込む。次に、左側の挿通孔１４ｂにも板状マグネット３６を挿入するが、押し込み片２２、２３の長さが異なるので、２枚の板状マグネット３６は挿通孔上部１５ａ、１５ｂにおいて水平方向に重ならず、板状マグネット３６が互いに磁気的に引き合うことはない。次に、押し込み部材２１により板状マグネット３６を挿通孔下部１６ａ、１６ｂの下端にまで押し込む操作を行うと、全体が挿通孔下部１６ａ、１６ａに移動した板状マグネット３６が水平方向に平行移動して平板３２に磁気的に吸引され、接着剤３５等が塗布された平板３２に固定される。
【００５４】
実施の形態（１）に係る板状部品の取り付け用治具１０によれば、板状マグネット３６の押し込みの際、２本の押し込み片２２、２３の長さが異なるため、押し込まれた板状マグネット３６の挿通孔上部１５ａ、１５ｂにおけるお互いの垂直方向の位置（高さ）が異なり、板状マグネット３６同士の磁気的な吸引力によりお互いが動きにくくなるといった事態は生じず、容易に板状マグネット３６を移動させることができる。また、押し込み部材２１の把持部２４には長い方の押し込み片２２を下方に付勢するコイルバネ２５が内装されているので、長い方の押し込み片２２による板状マグネット３６の押し込みが完了すると、コイルバネ２５が縮んで長い方の押し込み片２２の一部が把持部２４に形成された空洞部２４ａの中に入り込み、外部に突出している部分の長さが短くなり、このため短い方の押し込み片２３により板状マグネット３６を挿通孔下部１６ｂの下端にまで押し込んで、板状マグネット３６を平板３２に固定することができる。
【００５５】
このように、本実施の形態に係る押し込み部材２１を用いて板状マグネット３６を挿通孔下部１６ａ、１６ｂに押し込むという簡単な操作により、２枚（１対）の板状マグネット３６を２枚の平板３２の内側の正確な位置に、容易かつ迅速に固定することができる。
【００５６】
把持部２４に配設された弾性体は、コイルバネ２５に限定されるものではなく、長い方の押し込み片２２を下方に付勢することができる部材であれば、ゴム状弾性体等、他の部材であっても差し支えない。
【００５７】
図３（ａ）は実施の形態（２）に係る板状部品の取り付け用治具を構成する取り付け部材を模式的に示した断面図であり、（ｂ）は平面図である。
【００５８】
この取り付け部材４１には、２つの挿通孔上部４５ａ、４５ｂの上端近傍にその周囲にわたってテーパ部（斜面）４２が形成され、拡開している。挿通孔下部４６ａ、４６ｂは図１、及び図２に示した取り付け部材１１と同様に構成されている。
【００５９】
従って、この取り付け部材４１を用いると、挿通孔上部４５ａ、４５ｂのテーパ部４２が案内部となり、板状マグネット３６を容易に挿通孔上部４５ａ、４５ｂに挿入することができ、その結果、より容易に平板３２に板状マグネット３６を固定することができる。
【００６０】
図４は、実施の形態（３）に係る板状部品の取り付け用治具を構成する取り付け部材を模式的に示した斜視図である。
【００６１】
この取り付け部材５１においては、その上面であって２つの挿通孔１４ａ、１４ｂの周囲に傾斜面５２ａ、５３ａを有する案内部材５２、５３が傾斜面５２ａ、５３ａを挿通孔１４ａ、１４ｂ側に向けて配置されており、その他の部分は、図１及び図２に示した取り付け部材１１と同様に構成されている。
【００６２】
従って、この取り付け部材５１を用いると、挿通孔１４ａ、１４ｂ周囲の傾斜面５２ａ、５２ｂが案内部となり、板状マグネット３６を容易に挿通孔１４ａ、１４ｂに挿入することができ、その結果、より容易に平板３２に板状マグネット３６を固定することができる。

BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped component mounting jig, and more specifically, for mounting a plate-shaped component used when a plate-shaped magnet is mounted on a yoke constituting an optical pickup unit of a compact disc (CD) reproducing apparatus. It relates to a jig.
[0002]
[Prior art]
Grooves called pits are formed in the circumferential direction on the back side of the compact disc (CD). In the CD reproducing apparatus, reflection when the laser light from the laser light source installed in the pickup unit is irradiated onto the pits. The intensity of the light and the intensity of the reflected light when irradiated on the flat surface where the pits are not formed are read as digital signals, thereby reproducing information such as music and video recorded on the CD.
[0003]
However, it is difficult to rotate the CD on the turntable so that the pits on the back side of the CD do not shake left and right and up and down at all. Therefore, in order to keep the distance between the pit formed on the CD and the laser light source constant, a mechanism (tracking servo mechanism, focusing servo mechanism) in which the movable part of the optical pickup unit tracks the pit is adopted. Yes.
[0004]
That is, by passing a current through an electromagnet called a bobbin interposed between two plate magnets, the movable part of the optical pickup unit including the bobbin is finely moved up and down and left and right, thereby a laser light source at a predetermined distance. Has come to track the pit.
[0005]
FIG. 13 is a perspective view schematically showing the plate magnet and a yoke for fixing the plate magnet.
[0006]
The yoke 31 is composed of an H-shaped substrate 33 and two flat plates 32 erected substantially parallel on the substrate 33, and the constituent material is a magnetic material such as iron. The plate-like magnet 36 is as small as several mm in length and width and about 1 mm in thickness, and is composed of a strong magnet such as neodymium.
[0007]
Conventionally, in order to attach the plate-shaped magnet 36 to the yoke 31, the plate-shaped magnet 36 that has been prepared by applying an adhesive 35 to the inside of the flat plate 32 of the yoke 31 and cutting a quadrangular prism-shaped magnet, It was adhered to the inside of the flat plate 32 by hand.
[0008]
[Problems to be solved by the invention]
However, since the magnetic force of the plate-like magnet 36 is strong, there is a problem that when the plate-like magnet 36 is attached to the flat plate 32, the plate-like magnets 36 are attracted and attracted easily, and the attachment is difficult.
[0009]
Further, since the plate magnet 36 is very small as described above, it is difficult to handle, and since it is easily attracted to the iron yoke 31, there is a problem that it is difficult to adhere to the flat plate 32 at an accurate position.
[0010]
Further, the plate magnet 36 must be bonded to the flat plate 32 so that the direction of the magnetic pole is constant. After the plate magnet 36 is produced and separated by the cutting operation, the polarity (N, S) is obtained. Therefore, it is difficult to discriminate the plate magnet 36 from the wrong direction of the magnetic pole.
[0011]
Further, when the plate magnet 36 is accurately bonded to the flat plate 32, a method of bonding the plate magnet 36 while sliding the plate magnet 36 as shown in FIG. 14 is also conceivable. In this method, an adhesive applied to the flat plate 32 is used. 35 is placed below and adheres to unnecessary portions such as the surface of the substrate 33.
[0012]
The present invention has been made in view of the above problems, and a plate-like component capable of accurately and quickly fixing a plate-like component to these flat plates or the like of a metal component in which two flat plates are erected on a substrate. The purpose is to provide a mounting jig.
[0013]
[Means for solving the problems and effects thereof]
  In order to achieve the above object, a plate-shaped component mounting jig (1) according to the present invention includes an inner side of both flat plates in a metal component in which two opposing flat plates are erected on a substrate substantially in parallel. In addition, a jig for mounting plate-like parts for fixing a pair of plate-like parts,
  An upper portion of an insertion hole for inserting the plate-shaped component, and a lower portion of the insertion hole formed so as to be able to insert and remove the flat plate in order to fix the plate-shaped component that has passed through the upper portion of the insertion hole to the flat plate; The two insertion holes formed from the mounting member formed substantially perpendicular to the lower surface from the upper surface and parallel to each other;
  A gripping portion, two pushing pieces having different lengths for pushing in the two plate-like components extending from the gripping portion and inserted into the two insertion holes of the mounting member, and the gripping portion And a pushing member configured to include an elastic body that biases the longer pushing piece downward
  Consists ofAnd
  The shape of the upper portion of the insertion hole in plan view is substantially the same as the shape of the upper surface of the plate-like component, the vertical length of the lower portion of the insertion hole is substantially the same as the vertical length of the flat plate, and the horizontal length is the flat plate. And the thickness of the adhesive applied to the flat plate and the thickness of the plate-like component, and the height is substantially the same as the height of the flat plate.It is characterized by that.
[0014]
  According to the mounting jig (1) for the plate-like component,Since the shape in plan view of the upper portion of the insertion hole is substantially the same as the shape of the upper surface of the plate-like component, the plate-like component is loosely fitted when inserted into the upper portion of the insertion hole, and the plate-like component is inserted into the insertion portion. In the upper part of the hole, it does not tilt left and right. Therefore, the plate-like component can be pushed straight into the lower portion of the insertion hole without tilting back and forth.
  Further, since the vertical length of the lower portion of the insertion hole is substantially the same as the vertical length of the flat plate and the height is substantially the same as the height of the flat plate, the vertical length of the plate-like component is the same as that of the flat plate. If the height is substantially the same as the height of the flat plate (that is, the vertical length of the plate-like component is substantially the same as the vertical length of the lower portion of the insertion hole and the flat plate). If the height is substantially the same as the height of the lower part of the insertion hole and the flat plate), the plate-like component pushed straight down to the lower part of the insertion hole without being inclined left and right and back is sucked by the flat plate, The inside of the lower part of the insertion hole is translated in the horizontal direction toward the flat plate side and fixed to the flat plate.
  Therefore,The lower part of the insertion hole of the attachment member is aligned with the flat plate, the plate-like component made of a ferromagnetic material such as a plate-like magnet is inserted from the upper part of the insertion hole of the attachment member, and the pushing member When an operation of pushing down to the lower portion of the insertion hole is performed, the plate-like component moved to the lower portion of the insertion hole is magnetically attracted to the metal flat plate, and the plate-like component is applied to the flat plate to which an adhesive or the like is applied. Can be fixed.
[0015]
  At this time, since the lengths of the two pushing pieces of the pushing member are different, positions (heights) in the vertical direction in the insertion hole of the plate-like parts are different, and the plate-like parts are different from each other. The magnetic attraction force does not make it difficult for each other to move. In addition, the grip portion of the pushing memberAn elastic body is provided, and the length of the longer pushing piece protruding from the gripping portion is changed.Therefore, when the pushing of the plate-like component by the longer pushing piece is completed, the elastic body contracts and a part of the longer pushing piece is accommodated in the gripping part, and the protruding length is shortened. For this reason, the plate-like component can be pushed down to the lower portion of the insertion hole by the shorter pushing piece and fixed to the flat plate.
  In addition, the elastic body is housed in the gripping portion, and the length of the longer pushing piece protruding from the gripping portion changes, but the elastic body has the longer pushing piece downward. Therefore, the length of the longer pushing piece protruding from the gripping portion does not change until the pushing of the plate-like component by the longer pushing piece is completed. Therefore, it is possible to prevent the vertical positions (heights) of the plate-like components from being the same in the insertion hole.
[0016]
Thus, by aligning with the metal part of the mounting member, and by pushing the plate-like part into the lower part of the insertion hole using the pushing member, the two sheets (one pair) The plate-like component can be easily and quickly fixed at an accurate position inside the two flat plates.
[0017]
  The plate-shaped component mounting jig (2) according to the present invention is the above-described plate-shaped component mounting jig (1), wherein the distance between the outer wall surfaces of the lower portions of the two insertion holes is the distance between the two flat plates. It is characterized by being substantially the same as the distance between the outer facing surfaces.
[0018]
  According to the plate-shaped component mounting jig (2), the insertion hole lower portion has a vertical length substantially the same as a vertical length of the flat plate and a height substantially the same as the flat plate height, Since the distance between the outer wall surfaces of the two insertion hole lower portions is substantially the same as the distance between the outer facing surfaces of the two flat plates, the two flat plates of the metal part are inserted into the lower insertion hole portion. Thus, the positioning is automatically performed accurately, and the lower portion of the insertion hole is firmly fixed to the flat plate.
[0020]
The plate-shaped component mounting jig (3) according to the present invention is the plate-shaped component mounting jig (1) or (2), wherein the difference in length between the two pushing pieces is the plate. It is characterized by being larger than the height of the shaped part.
[0021]
According to the jig (3) for mounting the plate-like component, the difference in length between the two pushing pieces is larger than the height of the plate-like component, so that the two pieces pushed into the insertion hole The plate-like parts do not overlap in the horizontal direction, and the magnetic attraction force between the plate-like parts hardly acts in the insertion hole, and the two plate-like parts are moved smoothly by the pushing member. Can do.
[0022]
The plate-shaped component mounting jig (4) according to the present invention is an upper end of the two insertion holes formed in the mounting member in the plate-shaped component mounting jigs (1) to (3). The feature is that the neighborhood is widened.
[0023]
According to the plate-shaped component mounting jig (4), the vicinity of the upper ends of the two insertion holes formed in the mounting member is widened, so that the vicinity of the upper end is a guide portion of the plate-shaped component. Thus, the plate-like component can be easily inserted into the upper portion of the insertion hole.
[0024]
  Further, the plate-shaped component mounting jig (5) according to the present invention is provided around the two insertion holes on the upper surface of the mounting member in the plate-shaped component mounting jigs (1) to (4). And a guide member having an inclined surface causes the inclined surface toInsertion holeIt is characterized by being arranged toward the side.

A plate-shaped component detection through-hole communicating with the lateral wall surface of the plate-shaped component is formed, and an adhesive and plate-shaped component detection means for detecting the plate-shaped component are disposed in the plate-shaped component detection through-hole. It is characterized by.
[0027]
According to the plate-shaped component mounting jig (6), the plate-shaped component detection through hole is formed in the mounting member, and the plate-shaped component detection means is disposed in the plate-shaped component detection through hole. Therefore, it is possible to easily and quickly determine whether or not an adhesive is applied to the flat plate by the plate-shaped component detecting means, and whether or not the plate-shaped component is bonded. Occurrence of a situation where the plate-like component is attached without applying an adhesive or a situation where the metal component is removed from the attachment member while the plate-like component is not fixed can be prevented.
[0028]
The plate-shaped component mounting jig (7) according to the present invention is the plate-shaped component mounting jig (1) to (6), wherein the mounting member and the pushing member are made of a non-magnetic material. It is characterized by having.
[0029]
According to the plate-shaped component mounting jig (7), since the mounting member and the push-in member are made of a non-magnetic material, even if the plate-shaped component is a ferromagnetic material, The member is not attracted to the wall surface of the insertion hole of the mounting member, and the plate-like component can be easily moved by the pushing member inside the insertion hole.
[0030]

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a plate-shaped component mounting jig according to the present invention will be described below with reference to the drawings.
[0046]
The plate-shaped component mounting jig according to the embodiment is formed on the inner side of a flat plate erected on a yoke (metal component) that constitutes the optical pickup of the disk reproducing device described in the “Prior Art” section. Can be used effectively when fixing plate-shaped magnets (plate-shaped parts), but the use of the jig for mounting plate-shaped parts is not limited to the above-mentioned use, but two sheets facing each other Any other member can be used as long as the flat plate is a metal part erected on the substrate substantially in parallel.
[0047]
FIG. 1 is a perspective view schematically showing a plate-shaped component mounting jig and a yoke (metal component) for mounting a plate-shaped component according to the embodiment (1). (B) is sectional drawing which each showed the state in the middle of attaching a plate-shaped magnet (plate-shaped component) to a yoke (metallic component) using the said jig | tool for attachment of a plate-shaped component.
[0048]
The plate-shaped component attachment jig 10 according to the embodiment (1) is composed of an attachment member 11 and a pushing member 21.
[0049]
The attachment member 11 has a substantially rectangular parallelepiped shape, and is composed of a thin middle plate 12 at the center and a main body 13 disposed on the left and right sides thereof, and two insertion holes 14 (14a, 14b) sandwiching the middle plate 12 therebetween. Are formed substantially perpendicular to the lower surface from the upper surface and parallel to each other. These insertion holes 14a and 14b pass through the insertion hole upper portions 15a and 15b for inserting the plate magnet 36 and the insertion hole upper portions 15a and 15b. In order to fix the plate-shaped magnet 36 inside the flat plate 32 of the yoke 31, it is composed of rectangular parallelepiped insertion hole lower portions 16 a and 16 b that are formed so that the flat plate 32 can be inserted and removed.
[0050]
Further, when the plate-like magnet 36 is inserted into the insertion hole upper portions 15a and 15b, the insertion hole upper portions 15a and 15b are not easily dropped to the insertion hole lower portions 16a and 16b or tilted left and right and back and forth in the inserted state. The shape is substantially the same as the upper surface of the plate magnet 36 in plan view. The insertion hole lower portions 16a and 16b have a vertical length substantially the same as the vertical length of the flat plate 32 and a height substantially the same as the height of the flat plate 32, and the outer wall surfaces of the two insertion hole lower portions 16a and 16b. The distance between 160a and 160b is set to be substantially the same as the distance between the outer facing surfaces of the two flat plates 32. As shown in FIG. 2, the two flat plates 32 fit into the insertion hole lower portions 16a and 16b. Are automatically aligned accurately. In addition, the horizontal length of the insertion hole lower portions 16a and 16b is the thickness of the flat plate 32 and the adhesive applied to the flat plate 32 so that the plate magnet 36 pushed into the lower insertion hole portions 16a and 16b does not cut the adhesive 35. It is set to be larger than the sum of the thickness of the agent and the thickness of the plate magnet 36.
[0051]
The pushing member 21 includes a gripping part 24 and two pushing parts having different lengths for pushing the two plate magnets 36 extending from the gripping part 24 and inserted into the two insertion holes 14 of the mounting member 11. It comprises pieces 22 and 23 and a coil spring 25 that is housed in the gripping portion 24 and is an elastic body that urges the longer pushing piece 24 downward. The reason why the lengths of the push-in pieces 22 and 23 are different is that the plate-like magnets 36 are magnetically attracted to each other, so that when the plate-like magnets 36 are inserted into the insertion holes 14a and 14b, two plate-like pieces are used. This is to prevent the magnet 36 from overlapping in the horizontal direction in the insertion hole upper portions 15a and 15b. In order to prevent the two plate magnets 36 from completely overlapping in the horizontal direction, the difference in length between the two pushing pieces 22 and 23 is preferably larger than the height of the plate magnet 36.
[0052]
Since each of the attachment member 11 and the pushing member 21 is made of a nonmagnetic material such as aluminum, copper, or plastic, the plate magnet 36 is not attracted. Further, the insertion holes 14 a and 14 b are formed by performing groove processing on the main body 13.
[0053]
In order to fix the plate magnet 36 to the inside of the flat plate 32 erected on the yoke 31 using the plate-shaped component mounting jig 10 configured in this way, first, the flat plate 32 is attached to the mounting member 11. The plate-shaped magnet 36 is inserted into the right insertion hole upper portion 15a and fitted into the insertion hole lower portions 16a and 16b, and is pushed into the insertion hole upper portion 15a using the pushing piece 22. Next, the plate-like magnet 36 is inserted into the left insertion hole 14b. However, since the lengths of the pushing pieces 22 and 23 are different, the two plate-like magnets 36 are overlapped in the horizontal direction at the insertion hole upper portions 15a and 15b. In other words, the plate magnets 36 do not attract each other magnetically. Next, when the pusher member 21 is used to push the plate magnet 36 down to the lower ends of the insertion hole lower portions 16a and 16b, the plate magnet 36 that has moved to the insertion hole lower portions 16a and 16a is translated in the horizontal direction. Then, it is magnetically attracted to the flat plate 32 and fixed to the flat plate 32 coated with the adhesive 35 or the like.
[0054]
According to the plate-shaped component mounting jig 10 according to the embodiment (1), when the plate magnet 36 is pushed in, the lengths of the two pushing pieces 22 and 23 are different, so the pushed plate shape. The positions (heights) in the vertical direction of the insertion hole upper portions 15a and 15b of the magnet 36 are different from each other, and it is difficult to move each other due to the magnetic attractive force between the plate magnets 36. The magnet 36 can be moved. Further, since the holding portion 24 of the pushing member 21 is provided with a coil spring 25 for urging the longer pushing piece 22 downward, when the pushing of the plate magnet 36 by the longer pushing piece 22 is completed, the coil spring 25 is shrunk so that a part of the longer pushing piece 22 enters the cavity 24a formed in the gripping portion 24, and the length of the portion protruding to the outside is shortened. Thus, the plate magnet 36 can be pushed to the lower end of the insertion hole lower portion 16 b to fix the plate magnet 36 to the flat plate 32.
[0055]
As described above, two (one pair) of plate magnets 36 are formed by a simple operation of pushing the plate magnet 36 into the insertion hole lower portions 16a and 16b using the pushing member 21 according to the present embodiment. It can be easily and quickly fixed at an accurate position inside the flat plate 32.
[0056]
The elastic body disposed in the grip portion 24 is not limited to the coil spring 25, and any other member such as a rubber-like elastic body can be used as long as it is a member that can bias the longer pushing piece 22 downward. It may be a member.
[0057]
FIG. 3A is a cross-sectional view schematically showing an attachment member constituting the jig for attaching plate-like parts according to the embodiment (2), and FIG. 3B is a plan view.
[0058]
In the attachment member 41, a tapered portion (slope) 42 is formed in the vicinity of the upper ends of the two insertion hole upper portions 45a and 45b so as to expand. The insertion hole lower portions 46a and 46b are configured in the same manner as the attachment member 11 shown in FIGS.
[0059]
Therefore, when this attachment member 41 is used, the tapered portion 42 of the insertion hole upper portions 45a and 45b becomes a guide portion, and the plate magnet 36 can be easily inserted into the insertion hole upper portions 45a and 45b. The plate magnet 36 can be fixed to the flat plate 32.
[0060]
FIG. 4 is a perspective view schematically showing an attachment member constituting the plate-shaped component attachment jig according to the embodiment (3).
[0061]
  In the mounting member 51, the guide members 52 and 53 having the inclined surfaces 52a and 53a around the two insertion holes 14a and 14b on the upper surface thereof are formed into the inclined surfaces 52a and 53a.Insertion holeIt arrange | positions toward 14a, 14b side, and the other part is comprised similarly to the attachment member 11 shown in FIG.1 and FIG.2.
[0062]
Therefore, when this mounting member 51 is used, the inclined surfaces 52a and 52b around the insertion holes 14a and 14b serve as guide portions, and the plate magnet 36 can be easily inserted into the insertion holes 14a and 14b. The plate magnet 36 can be easily fixed to the flat plate 32.
[0063]

In addition, a plate-like component detecting means 63 for detecting the adhesive 35 and the plate-like magnet 36 is disposed. The plate-like component detecting means 63 is composed of a pair of infrared light emitting device 63a and infrared light receiving device 63b. The infrared light received from the infrared light emitting device 63a is received by the infrared light receiving device 63b, and the intensity of the received infrared light. Can be measured. A flat plate 32 constituting the yoke 31 is fitted inside the insertion hole lower portions 16a and 16b, and an adhesive 35 is applied to the inner surface of the flat plate 32. The intensity of the infrared light received by the infrared light receiving device 63b differs between the case where the adhesive 35 is applied to the inner surface of the flat plate 32 and the case where the adhesive 35 is not applied. Therefore, it is possible to determine whether or not the adhesive 35 is applied to the inner surface of the flat plate 32 by measuring the intensity of infrared rays. Further, when the plate magnet 36 is bonded to the inside of the flat plate 32, the infrared light receiving intensity is further greatly changed. It is also possible to determine whether or not the plate magnet 36 is fixed by measuring the infrared light receiving intensity.
[0065]
The plate-shaped component detection means 63 is not limited to the above-described infrared light emitting device 63a and infrared light receiving device 63b, and detects the plate-shaped magnet 36 and the adhesive 35 by an optical method, a method using electromagnetic waves, or the like. Any other device can be used as long as it can be used.
[0066]
When the attachment member 61 according to the embodiment (4) is used, whether or not the adhesive 35 is applied to the flat plate 32 by the plate-like component detecting means 63 and whether or not the plate-like magnet 36 is adhered to the flat plate 32. It is possible to easily and quickly determine whether the plate magnet 36 is attached to the flat plate 32 without the adhesive 35 applied thereto, or the yoke 31 is removed from the attachment member 61 without the plate magnet 36 being fixed. The occurrence of such a situation can be prevented.
[0067]

[0068]
A magnet (metal piece) 72 is embedded in the bottom of the mounting member 71. On the other hand, since the yoke 31 is made of a magnetic material, the flat plate 32 can be firmly fixed to the insertion hole lower portions 16a and 16b by attracting the yoke 31 with the magnet 72, and the insertion of the yoke 31 is insufficient. It is possible to prevent the fixing failure of the plate magnet 36 due to the above.
[0069]
FIG. 7: is sectional drawing which showed typically the attachment member which comprises the jig | tool for attachment of the plate-shaped component which concerns on Embodiment (6).
[0070]

[0071]
Accordingly, the plate magnet 36 is inserted into the insertion hole upper portions 85a and 85b of the mounting member 81, and air is sucked from the air suction through hole 82 while the plate member 36 is pushed into the insertion hole lower portions 86a and 86b by the pushing member 21. By doing so, the plate magnet 36 can be easily fixed to the flat plate 32.
[0072]
Further, by adjusting the dimensions of the insertion hole upper portions 85a and 85b and adjusting the strength of the sucked air, the plate-like magnet 36 inserted into the insertion hole upper portions 85a and 85b is inserted into the insertion hole lower portion 86a by air. , 86b, and then sucked and fixed to the flat plate 32. In this case, the pushing member 21 is not required.
[0073]
In the plate-shaped component mounting jigs according to the above-described embodiments (1) to (5), the plate-shaped magnet 36, which is a ferromagnetic material, is fixed to the flat plate 32 of the yoke 31 made of a magnetic material such as iron. However, if the mounting member 81 having the air suction through-hole 82 as shown in FIG. 7 is used, the plate-like component 36 is not a ferromagnetic plate-like magnet, but a metal. Even when the manufactured part 31 is not a magnetic yoke, the plate-like part 36 can be fixed to the flat plate 32 erected on the metal part 31.
[0074]
