Abstract

<P>PROBLEM TO BE SOLVED: To provide a component feeder and a component mounter which are not dangerous even if unused power supply terminals are exposed and can be fixed/removed without requiring any operation of a power switch, and to provide their electrical connecting method. <P>SOLUTION: When a power supply connector 53 and a power receiving connector 38 are not connected, a power supply switch 58 to a power supply terminal 55 is opened to interrupt the driving current (a) supply, and only a small current (b) passing through R1 is applied thus eliminating dangers. When a component feeder is set to a component mounter, a switch SW 67 interlocked with a lock lever 39 closes to connect the power supply connector 53 automatically with the power receiving connector 38, and a power supply request signal (c) is delivered from a current detecting section 66 when the small current (b) is detected. Upon receiving that signal, the control section 59 of the component mounter 50 closes the power switch 58 to supply the driving current (a) to the component feeder 35. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
本発明は、部品供給装置とこの部品供給装置から電子部品を取り出してプリント基板の所定の位置に搭載する電子部品搭載装置とこれら部品供給装置と部品搭載装置との電気接続方法に関する。
【０００２】
【従来の技術】
従来より、基板ユニット製造ラインの中にあって、チップ状の電子部品をプリント基板の所定の位置に自動搭載する部品搭載装置と、この部品搭載装置に電子部品を供給する例えばテープカセット式の部品供給装置がある。
【０００３】
図５（ａ）　は、部品搭載装置の外観斜視図であり、同図（ｂ）　は、その上下の保護カバーを取り除いて内部の構成を模式的に示す斜視図である。同図（ａ）　に示すように、部品搭載装置１は、天井カバー上の前後に、それぞれＣＲＴディスプレイからなるモニタ装置２と、同じく天井カバー上の左右に、それぞれ稼動状態を報知する警報ランプ３を備えている。また、上部保護カバー４の前部と後部の面には、液晶ディスプレイとタッチ式入力装置からなり外部からの操作により各種の指示を入力することができる小型の表示入力パネル５が配設されている（図の左斜め上方向になる後部の表示入力パネル５は陰になって見えない）。
【０００４】
下部の基台６の上には、中央に、固定と可動の１対の平行する基板案内レール７が同図（ｂ）　に示すプリント基板（以下、単に基板という）８の搬送方向（Ｘ軸方向、図の斜め左下から斜め右上方向）に水平に延在して配設される。これらの基板案内レール７の下部に接して、図には見えないが、ループ状の搬送ベルト（コンベアベルト）が走行可能に配設される。
【０００５】
搬送ベルトは、それぞれ数ミリ幅のベルト脇部を基板案内レール７の下から基板搬送路に覗かせて、不図示のベルト駆動モータにより駆動され、基板搬送方向に走行し、基板８の裏面両側を下から支持しながら装置本体内に部品搭載前の基板８をライン上流側から搬入し、部品搭載済みの基板８を順次ライン下流側に搬出する。この部品搭載装置１内には、常時２枚の基板８が搬入され、位置決めされて、電子部品の搭載が終了するまで固定されている。
【０００６】
基台６の前後には、それぞれ部品供給ステージ９が形成されている（左斜め上方向になる後部の部品供給ステージ９は、同図（ａ）　では陰になって見えない。また同図（ｂ）　では図示を省略している）。部品供給ステージ９には、テープカセット式電子部品供給装置（以下、単に部品供給装置という）１１が、５０個〜７０個と多数配置される。また、部品供給ステージ９の装置内側近傍に撮像カメラ１０が配設されている。
【０００７】
また、基台６の上方には、二本のＸ軸レール１２とこのＸ軸レール１２上にＸ軸方向（図の左斜め下から右斜め上方向）に摺動自在に支持されたＹ軸レール１３とが、それぞれ左右に配置され、それぞれのＹ軸レール１３には、２台の作業ヘッド支持塔１４がＹ軸方向（図の右斜め下から左斜め上方向）に摺動自在に懸架されている。つまりここに示す部品搭載装置１には合計４台の作業ヘッド支持塔１４が配設されている。
【０００８】
各作業ヘッド支持塔１４には、図の例では２個の作業ヘッド１５が上下（Ｚ方向）に昇降自在に且つ３６０度方向（θ方向という）に回転自在に配設されている。すなわち、部品搭載装置１には合計８個の作業ヘッド１５が配設されており、各作業ヘッド１５は、Ｙ軸レール１３によるＸ軸方向への移動、作業ヘッド支持塔１４によるＹ軸方向への移動、及び作業ヘッド１５自身によるＺ軸方向への移動とθ方向への回転により、前後左右上下及び３６０度方向への位置を自在に制御される。これらの作業ヘッド１５は、部品供給装置１１から供給される所定の電子部品を吸着ノズルによって吸着し、その吸着した電子部品を基板８の所定の搭載位置に搭載する。
【０００９】
尚、作業ヘッド支持塔１４には、特には図示しないが、基板８への電子部品搭載位置を確認するための基板面撮像装置が、作業ヘッド１５の近傍に配設されている。また基台６の内部には、特には図示しないが、基板の位置決め装置、基板を２本の基板案内レール７間に固定する基板固定機構、各部を制御するための制御装置、後述するコネクタに電源を供給する電源制御部等が備えられている。
【００１０】
図６は、部品搭載装置の部品供給ステージ上に配設された部品供給装置を一つのみ取り上げて詳しく示す斜視図である。同図に示すように部品供給ステージ９には多数の取り付け固定孔１６が前後に設けられ、これらの取り付け固定孔１６によって部品供給装置１１が部品供給ステージ９に位置固定して配置される。部品供給装置１１には電子部品を収容した部品テープが巻着されているリール１７がリール保持部に保持されている。
【００１１】
この部品搭載装置１は、先ず、部品供給ステージ９に位置固定して配置された部品供給装置１１において、リール１７の部品テープが部品供給口１８まで引き出され、トップテープ１９と収容テープ２１とに分離され、収容テープ２１に収容されている電子部品が部品供給口１８に露出する。この露出した電子部品を、図５（ａ），（ｂ）　に示した部品搭載装置１の作業ヘッド１５が吸着ノズルによって吸着して取り出し、その吸着した電子部品を撮像カメラ１０で画像認識して吸着状態の位置（姿勢）の補正を行って、その電子部品を基板８上に搭載する。
【００１２】
上記分離されたトップテープ１９は巻取リール２２に巻き取られ、電子部品を供給して空になった収容テープ２１は部品供給ステージ９の下方に自由落下して堆積する。
部品供給ステージ９には、部品搭載装置１の大きさや供給される電子部品の大きさにもよるが、通常、５０〜７０個の部品供給装置１１が取り付けられる。つまり前後の部品供給ステージ９を合わせると１００〜１４０個の部品供給装置１１が１台の部品搭載装置１に配設される。
【００１３】
一般に部品供給装置１１は、一番小さいもので部品テープの幅は８ｍｍであり大きいものでは５０ｍｍ幅の部品テープを収容しているものもある。部品供給ステージ９の取り付け固定孔１６は、一番小さい８ｍｍ幅の部品テープを収容する部品供給装置１１を並べて配置できるように形成されている。
【００１４】
旧来は、部品供給装置１１の上述した部品供給口１８に電子部品が供給されるには、部品テープを間歇的に繰り出す部品供給装置１１側のラッチ車のラッチレバーを、部品搭載装置１の作業ヘッド支持塔１４に設けられている突起部で押し込んで、部品テープを繰り出すと共に巻取リール２２を回転させてトップテープ１９を強制的に収容テープ２１から剥ぎ取るということで、電子部品を露出させて部品供給口１８に供給していた。
【００１５】
しかし、これでは電子部品の吸着と基板への搭載が本来の目的である部品搭載装置１の作業ヘッド支持塔１４に、突起部でラッチレバーを押すという、本体の目的から離れた作業をさせる時間を要することになり、その分だけ電子部品を吸着して基板へ搭載するまでの全体の作業時間が長くなり、近年の部品搭載作業の高速化が指向される風潮の中では、作業能率の向上を阻害するという問題を有する部品供給方式であった。
【００１６】
更に、部品テープの幅が５０ｍｍと大型のものになると、作業ヘッド支持塔１４の突起部でラッチレバーを押して大型の部品テープを繰り出すには数回の押し動作が必要となって益々本来の目的外の動作に時間を取られることになって作業能率が低下する。
【００１７】
そこで、部品供給装置１１側にモータを備え、このモータで部品テープの繰り出し駆動と巻取リール２２の回転駆動を行うようにしたものが実用化され出した。この場合、部品供給装置１１側に電源を持つことは実用的でないので、部品搭載装置１の電源を利用し、図６に示すように、部品供給ステージ９の側面に取り付け固定孔１６に対応する数だけの電源供給コネクタ２３を配設し、この電源供給コネクタ２３に部品供給装置１１の電源受給コネクタ２４を接続するようにしたものが実用化されている。
【００１８】
両コネクタは、それぞれ電源端子と信号線端子を備え、コネクタ接続後は電源端子を介して部品搭載装置１の電源から部品供給装置１１へ電力が供給され、信号線端子を介して部品搭載装置の制御部から部品供給装置１１の諸動作が制御される。
【００１９】
【発明が解決しようとする課題】
ところで、部品供給装置１１を部品搭載装置１の部品供給ステージ９に取り付けるとき電源スイッチが入力になったまま電源供給コネクタ２３に電源受給コネクタ２４を接続したり、あるいは部品供給装置１１を部品搭載装置１の部品供給ステージ９から取り外すとき電源スイッチが入力になったまま電源供給コネクタ２３から電源受給コネクタ２４を脱抜すると、コネクタの電源端子間にサージ電圧による放電が発生する場合が多々ある。
【００２０】
このように、放電が発生すると、放電のアークは極めて高温であるから、電源端子を形成している金属接点を溶融して損傷させ、その寿命を短くしてしまうという問題や、放電によるノイズが発生して、まだ稼動中の同じ電源を共有している他の装置に悪影響を与えるなどの問題があって好ましいものではなかった。
【００２１】
また、部品供給ステージ９は常に部品供給装置１１で塞がっているわけではなく、他の形式の部品供給装置が連結されている場合、あるいは製造される基板ユニットの仕様上から、それほど多くの部品供給装置１１を必要としない場合などでは、部品供給ステージ９上には部品供給装置１１の空席が形成される。この部品供給ステージ９の空席の下方側面に形成されている電源供給コネクタ２３は、部品供給装置１１の電源受給コネクタ２４が接続されていないので端子が露出してしまうが、この端子には、家庭内の商業用電源コンセントの場合と同様に常に電源電流が印加されている。
【００２２】
したがって、取り付けネジ等の部品や金属性部材などが落下して、上記のように露出している電源供給コネクタ２３の端子に接触したり、生産従事者が誤って作業中の工具等の金属性部材を接触させたりすると、電源供給コネクタ２３の端子間で短絡が発生し、この場合も、同じ電源を共有している他の部品供給装置などに、一時的な電源電圧の低下やノイズの発生等の悪影響を与えるという問題があった。
【００２３】
従来は、部品供給装置１１の適宜の位置に電源スイッチを配置して、部品供給ステージ９に部品供給装置１１を取り付け、電源供給コネクタ２３に電源受給コネクタ２４を接続してから電源スイッチを入れ、部品供給ステージ９から部品供給装置１１を取り外すときは、電源供給コネクタ２３から電源受給コネクタ２４を脱抜する前に電源スイッチを切るという方法で上記の問題を解消する以外に方法が無かった。
【００２４】
しかし、この方式は、狭い間隔で多数配置される部品供給装置１１の狭い間隙の中で、誤り無く電源スイッチを操作することは面倒であるという不満が残るものであった。
また、部品供給ステージ９の側面に形成されている電源供給コネクタ２３は、部品供給ステージ９に装着された部品供給装置１１の外部方向に突出するリール１７を保持するリール保持部の直下となるため、この電源供給コネクタ２３に部品供給装置１１の電源受給コネクタ２４を接続する場合、その都度、生産従事者は腰を曲げるか、かがみ込んで、リール保持部の下方を覗き込んで電源供給コネクタ２３の位置を確認しながら電源受給コネクタ２４を接続するという作業方式を採ることになる。これがなかなか面倒で且つ労力の要る作業であって能率が低下するという問題もあった。
【００２５】
本発明の課題は、上記従来の実情に鑑み、部品搭載装置に対する部品供給装置の取り付け取り外しの際に生産従事者が部品供給装置の電源スイッチを操作する手数を取り除くとともに、非使用中で外部に露出する電源供給コネクタの端子に何らの不具合も発生しない部品供給装置、部品搭載装置、及びその電気接続方法を提供することである。
【００２６】
【課題を解決するための手段】
以下に、本発明に係わる部品供給装置、部品搭載装置、及びその電気接続方法の構成を述べる。
先ず、請求項１記載の発明の部品搭載装置は、電源と、少なくとも電源供給端子と信号送受信端子とを有する電源供給コネクタと、上記電源と上記電源供給端子との間に電流制限抵抗と並列に接続された電源供給スイッチと、上記電源から上記電源供給端子への駆動電流を、上記電源供給コネクタが外部の電源受給コネクタと非接続のとき遮断し、上記電源供給コネクタが上記電源受給コネクタと接続しているとき通電させるよう上記電源供給スイッチの開閉を制御する電源制御手段と、を備えて構成される。
【００２７】
この部品搭載装置は、例えば請求項２記載のように、上記電源供給コネクタに接続された外部の電源受給コネクタから上記信号送受信端子を介して入力される駆動電流要求信号を検出する信号検出手段を更に備え、上記電源制御部は、上記信号検出手段が上記駆動電流要求信号を検出したとき上記電源供給スイッチを閉路状態に制御するように構成される。
【００２８】
また、上記電源制御部は、例えば請求項３記載のように、上記電源供給コネクタに接続された外部の電源受給コネクタに供給する駆動電流の所定の位置の電位差を監視することにより、上記電源受給コネクタが上記電源供給コネクタから離脱したことを認識し、この認識に基づいて、上記電源供給スイッチを開路状態に制御するように構成される。
【００２９】
次に、請求項４記載の発明の部品供給装置は、少なくとも電源受給端子と信号送受信端子とを有する電源受給コネクタと、該電源受給コネクタと該電源受給コネクタに接続されるべき外部の電源供給コネクタとを自在に接続または離脱させる操作機構と、上記電源受給コネクタに接続された上記電源供給コネクタから上記電源受給コネクタの上記電源受給端子を介して入力される微弱電流を検出し該検出に基づいて自装置への駆動電流を要求する駆動電流要求信号を上記信号送受信端子を介して上記電源供給コネクタへ出力する微弱電流検出兼駆動電流要求手段と、上記操作機構の操作により上記電源受給コネクタと上記電源供給コネクタとが接続されたとき上記操作機構の操作に連動して上記電源受給端子から負荷部への駆動電流受給路を導通させるべく閉路する電源受給スイッチと、を備えて構成される。
【００３０】
この部品供給装置は、例えば請求項５記載のように、上記電源受給コネクタを上記電源供給コネクタから離脱させるべく上記操作機構が操作されたとき該操作機構の操作に連動して、上記電源受給スイッチは開路して上記電源受給端子から負荷部への電源受給路を遮断するように構成される。
【００３１】
そして、請求項６記載の発明の部品供給装置と部品搭載装置の電気接続方法は、部品搭載装置の電源供給コネクタに部品供給装置の電源受給コネクタが接続されていないとき、電流制限回路による微弱電流のみを上記電源供給コネクタの電源供給端子に印加する工程と、上記電源受給コネクタが上記電源供給コネクタに接続されたとき上記部品供給装置から上記電源受給コネクタ及び上記電源供給コネクタを介して上記部品搭載装置に駆動電流の供給を要求する信号を出力する工程と、該駆動電流の供給を要求する信号に基づいて上記部品搭載装置の電源から上記電源供給コネクタ及び電源受給コネクタを介して上記部品供給装置に駆動電流の供給を開始する工程と、を含んで構成される。
【００３２】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しながら説明する。
図１は、一実施の形態における部品搭載装置の制御システムの構成を示すブロック図である。尚、部品搭載装置の外観及び内部のハード構成は、図５（ａ），（ｂ）　に示した部品搭載装置１の構成と、部品供給ステージ９の構成を除いてほぼ同様である。
【００３３】
図１に示すように、本例における部品搭載装置の制御システムは、制御部２５にバス２６を介して接続された撮影部２７、吸着ノズル部２８、コネクタ部２９、記憶部３０、Ｙ軸モータドライバ３１、Ｘ軸モータドライバ３２、Ｚ軸モータドライバ３３、及び回転モータドライバ３４が設けられている。
【００３４】
上記の撮影部２７は、作業ヘッドの吸着ノズル先端の位置補正や吸着ノズルに吸着された電子部品の位置補正を行うために基台側に配設されている撮像カメラや、基板の電子部品搭載位置を確認するために作業ヘッド支持塔側に配設されている撮像カメラを駆動制御する回路である。
【００３５】
また、吸着ノズル部２８は、各作業ヘッド支持塔に支持されている各作業ヘッドの吸着ノズルに連結されている吸引パイプの空気圧を制御する回路である。
コネクタ部２９は、後述する部品供給ステージの電源供給コネクタを介して部品供給装置へ供給する電力の供給制御を行う電源制御部や、制御信号の送受信を行う信号検出部、更には部品供給装置と送受信される信号を制御部２５との間で仲介するＩ／Ｆ（インターフェース）部等からなる回路である。
【００３６】
記憶部３０は、ＲＯＭ（ｒｅａｄ　ｏｎｌｙ　ｍｅｍｏｒｙ）、ＲＡＭ（ｒａｎｄｏｍ　ａｃｃｅｓｓ　ｍｅｍｏｒｙ）、さらには各種のデスク装置ドライバ等を有する回路であり、ＲＯＭには制御部２５に各種の処理を実行させるプログラムが記憶されている。ＲＡＭにはデスク装置から読み込まれた各種のデータ、又は制御部２５が行う各種演算の中間データを一時的に記憶する記憶領域が備えられている。
【００３７】
更に、Ｙ軸モータドライバ３１は、各Ｙ軸レールが支持するＸ軸レールをそれぞれ所望のＹ軸方向に移動駆動するＹ軸モータの駆動回路である。
Ｘ軸モータドライバ３２は、各Ｘ軸レールが支持する作業ヘッド支持塔をそれぞれ所望のＸ軸方向へ移動駆動するＸ軸モータの駆動回路である。
【００３８】
Ｚ軸モータドライバ３３は、各作業ヘッド支持塔に支持される作業ヘッドをそれぞれ所望のＺ軸方向へ昇降駆動させるＺ軸モータの駆動回路である。
そして、回転モータドライバ３４は、各作業ヘッド支持塔に支持される作業ヘッドを、それぞれ所望の３６０度方向へ回転駆動するθ軸モータの駆動回路である。
【００３９】
図２は、上記部品搭載装置の部品供給ステージに着脱自在に装着される部品供給装置の側面図である。同図に示す部品供給装置３５は、テープ式の部品供給装置である。生産従事者は、部品供給装置３５の取っ手３６を持って自在に持ち運び、部品搭載装置の部品供給ステージの所定の箇所に装着する。
【００４０】
装着に際しては、部品供給装置３５の前方（図の左方）下部に設けられた係合レール３７を部品供給ステージに形成されている係合溝に嵌入させて位置決めしながら装着する。装着が完了すると、電源受給コネクタ３８が、後述するように部品搭載装置の部品供給ステージに設けられている電源供給コネクタに自動的に接続されると共に、操作機構としてのロックレバー３９の回動に連動するロック金具４１により部品供給ステージに固定され、且つロックレバー３９の回動に連動する部品供給装置３５の後述する電源受給スイッチが閉じられる。同図に示すロックレバー３９及びロック金具４１の状態は、それぞれ部品供給装置３５を部品供給ステージに装着して固定したときの状態を示している。
【００４１】
この部品供給装置３５は、後端部（図の右方端部）にリール保持部４２を備え、このリール保持部４２に、部品テープを捲着したリール４３を着脱自在に保持できる。リール４３から引き出された部品テープは、装置内部のテープ搬送経路４４を通り抜け、テープへの案内と浮き上がり防止を兼ねるテープ押圧部材４５の下を通って、部品供給口４６まで引き出される。部品供給口４６まで引き出された部品テープは、トップテープと収容テープの上下２枚合わせのテープが剥離されて下部の収容テープ上に電子部品が露出する。この露出した電子部品が部品搭載装置の作業ヘッド先端の吸着ノズルによって吸着されて取り出される。
【００４２】
上下に剥離された上側のトップテープはテープ回収容器４７に回収され、下側の収容テープは部品供給装置３５本体内の排出路を通過して、図の矢印Ａで示すように、外部下方に落下して堆積する。
図３（ａ），（ｂ）　は、上記の部品供給装置３５を、部品搭載装置の部品供給ステージに装着する際の装着方法と電気的接続方法を簡略な模式図で示す図である。尚、同図（ａ），（ｂ）　には、図２に示した構成と同一の構成部分には図２と同一の番号を付与して示している。
【００４３】
先ず、部品供給装置３５を部品搭載装置に装着する際は、同図（ａ）　に示すように、部品供給装置３５の後端（図では右端）上部に設けられているロックレバー３９を支持ピン４８を支点にして、図の矢印Ｂで示すように上後方（図では右上方向）に引き上げて図の時計回り方向に回動させると、これに連動してロック金具４１が図２に示した固定状態から前上方向（図３（ａ）　では左上方向）つまり図３（ａ）　の時計回り方向に回動して持ち上がる。また、同様にロックレバー３９の上記時計回り方向への回動に連動してロック検出スイッチ４９が開路して詳しくは後述する駆動電流受給路を予め遮断する。
【００４４】
図３（ａ）　に示すように、部品搭載装置５０の部品供給ステージ５１には、部品供給装置３５の各装着位置ごとに、部品供給装置３５の係合レール３７に対応する係合溝５２が穿設されており、その係合溝５２の下方側面には電源供給コネクタ５３が配設されている。
【００４５】
上記のように前上方に回動して持ち上がったロック金具４１が、係合溝５２への係合レール３７の進入路を開放していることにより、作業従事者は、係合レール３７の先端を、係合溝５２の手前端部（図の右端部）に容易に差し込むことができる。そして、作業従事者は、そのまま係合レール３７を、同図（ａ）　に示すように、係合溝５２に挿通させながら、同図（ｂ）　に示すように、最終位置まで部品供給装置３５を押し込んでいく。これにより、電源受給コネクタ３８が電源供給コネクタ５３に自動的に接続される。
【００４６】
この後、作業従事者は、図３（ｂ）　に示すように、ロックレバー３９を反時計回り方向へ回動させて倒し込み、これに連動するロック金具４１を反時計回り方向に回動させる。これにより、ロック金具４１の鉤型の先端が部品供給ステージ５１の端部を咥え込むように下面に回り込んで、部品供給ステージ５１に係止し、部品供給装置３５が部品供給ステージ５１に固定される。また、これと同時に上記ロックレバー３９の反時計回り方向への回動に連動してロック検出スイッチ４９が閉路して詳しくは後述する駆動電流受給路を導通させる。
【００４７】
図４（ａ）　は、上記の電源供給コネクタ５３とこれに関わる回路ブロック図及び電源受給コネクタ３８とこれに関わる回路ブロック図であり、同図（ｂ）　は電源供給コネクタ５３に関わる回路ブロック図の電源制御部の内部回路図である。
図４（ａ）　に示すように、部品搭載装置５０は、電源５４と、少なくとも電源供給端子５５と信号送受信端子５６（５６−１、５６−２）とを有する電源供給コネクタ５３と、電源５４と電源供給端子５５との間に電源制御部５７を備えている。電源制御部５７は、同図（ｂ）　に示すように、電源５４と電源供給端子５５との間に並列に接続された電流制限抵抗Ｒ１と電源供給スイッチ５８、及びこの電源供給スイッチ５８の開閉を制御する電源制御手段としての制御部５９とから成る。
【００４８】
上記の電源供給スイッチ５８は、例えばスイッチングＦＥＴ（ｆｉｅｌｄ　ｅｆｆｅｃｔ　ｔｒａｎｓｉｓｔｏｒ）であり、制御部５９によりベースにスイッチ駆動電圧を印加されることにより閉路して電源５４と電源供給端子５５間に駆動電流ａを導通させ、スイッチ駆動電圧の印加を解除されることにより開路して電源５４と電源供給端子５５間の駆動電流ａを遮断する。
【００４９】
他方、電流制限抵抗Ｒ１は、例えば数十Ωの大抵抗値を有する抵抗回路であり、電源供給スイッチ５８が開路して電源供給端子５５への駆動電流ａの供給を遮断しているとき、電流制限抵抗Ｒ１は微弱電流ｂを通過させて、この微弱電流ｂを電源供給端子５５へ供給する。
【００５０】
上記の制御部５９は、電源供給コネクタ５３が外部の電源受給コネクタ３８と非接続のとき、電源供給スイッチ５８が開路して電源５４から電源供給端子５５への駆動電流ａを遮断し、電源供給コネクタ５３が電源受給コネクタ３８と接続しているとき、電源供給スイッチ５８が閉路して電源５４から電源供給端子５５への駆動電流ａを通電させるよう電源供給スイッチ５８を制御する。
【００５１】
上記の制御部５９による電源供給スイッチ５８を閉路させる制御を行うための電源供給コネクタ５３と電源受給コネクタ３８との接続の検知は、電源供給コネクタ５３に電源受給コネクタ３８が接続されてから電源受給コネクタ３８から信号送受信端子５６−１を介して入力される駆動電流要求信号ｃを信号検出手段としての信号検出部６１が検出し、信号検出部６１がこの検出した駆動電流要求信号ｃを制御部５９に通知することによって検知される。
【００５２】
尚、電源供給コネクタ５３に電源受給コネクタ３８が接続された後の、制御信号その他の信号の送受信は、信号送受信端子５６−２を介して行われ、信号送受信端子５６−２には、Ｉ／Ｆ（インターフェース）回路６２を介して部品搭載装置本体側の図１に示した制御部２５が接続されている。また、上記信号検出部６１により検出された駆動電流要求信号ｃは、コネクタ接続完了信号ｄとして制御部２５に通知される。これにより、制御部２５は、部品供給装置３５への制御を開始する。
【００５３】
尚、図４（ａ）　に示す電源制御部５７、信号検出部６１、Ｉ／Ｆ（インターフェース）回路６２、及び接地回路６３は、図１に示すコネクタ部２９を形成している。また、同図（ｂ）　に示す抵抗Ｒ２は、例えば０．０２Ω程度の微小抵抗値を有する抵抗回路であり、電源供給スイッチ５８の閉路初期の突入電流を抑止するために設けられている。
【００５４】
他方、部品供給装置３５は、図４（ａ）　に示すように、少なくとも電源受給端子６４と信号送受信端子６５（６５−１、６５−２）とを有する電源受給コネクタ３８と、電源受給コネクタ３８とこの電源受給コネクタ３８に接続されるべき外部の電源供給コネクタ５３とを自在に接続または離脱させる操作機構としてのロックレバー３９と、微弱電流検出兼駆動電流要求手段としての電圧検出部６６と、上記ロックレバー３９の操作に連動して開閉する電源受給スイッチＳＷ６７と、負荷部電気回路６８を備えている。
【００５５】
電源受給スイッチＳＷ６７は、例えばマイクロスイッチ等であり、特には図示しないが、例えばロックレバー３９の図３（ａ），（ｂ）　に示す支点４８より反対側に例えば９０度の角度で突出してロックレバー３９と一体に形成された連動レバーによってスイッチボタンを押し込まれて閉路し、その押し込みを解除されて開路するスイッチである。
【００５６】
この電源受給スイッチＳＷ６７と電源受給端子６４との中間の分岐点と信号送受信端子６５−１との間に微弱電流検出兼駆動電流要求手段としての電圧検出部６６が配設されている。電源受給コネクタ３８が電源供給コネクタ５３に接続されると、電源制御部５７の同図（ｂ）　に示す抵抗Ｒ１を介して流れる微弱電流ｂが電源供給コネクタ５３の電源供給端子５５及び電源受給コネクタ３８の電源受給端子６４を介して部品供給装置３５の駆動電流受給路７１−１に供給される。
【００５７】
駆動電流受給路７１−１は電源受給端子６４と電源受給スイッチＳＷ６７の入力側端子とを接続している回路であり、途中の分岐点から信号送受信端子６５−１との間に電圧検出部６６が直列に接続されている。電圧検出部６６は、分岐点から流入する部弱電流ｂを検出し、この検出した部弱電流ｂに基づいて駆動電流要求信号ｃを、信号送受信端子６５−１及び電源供給コネクタ５３の信号送受信端子５６−１を介して部品搭載装置５０の信号検出部６１に送信する。
【００５８】
これにより、上述したように、部品搭載装置５０では、信号検出部６１が駆動電流要求信号ｃを検出して、この駆動電流要求信号ｃを制御部５９に通知することによって、電源供給スイッチ５８が閉路し、電源５４からの駆動電流ａが、部品供給装置３５の駆動電流受給路７１−１に供給される。この後、ロックレバー３９が図３（ｂ）　に示す固定側に操作されて、この操作に連動して電源受給スイッチＳＷ６７が閉路する。これにより駆動電流受給路７１−１から駆動電流受給路７１−２に駆動電流ａが流れて、部品供給装置３５の負荷部電気回路６８に駆動電流ａが供給される。
【００５９】
尚、電源受給コネクタ３８が電源供給コネクタ５３に接続された後の、制御信号その他の信号の送受信は、信号送受信端子６５−２を介して行われ、この信号送受信端子６５−２には、Ｉ／Ｆ回路６９を介して部品供給装置３５の負荷部電気回路６８が接続されている。
【００６０】
上記のように部品供給装置３５の負荷部電気回路６８が電源受給スイッチＳＷ６７の閉路によって電源受給端子６４に接続される前に、つまり負荷が電源受給コネクタ３８の電源受給端子６４に接続されていない状態で電源受給コネクタ３８が電源供給コネクタ５３に接続されるので、両コネクタの給電・受給端子間に接続時の接点スパークなどは発生しない。
【００６１】
また、電源受給コネクタ３８と電源供給コネクタ５３との接続が解除されるのは部品供給装置３５が部品搭載装置５０から脱抜されたときである。部品供給装置３５を部品搭載装置５０から脱抜するには、先ず、ロックレバー３９を図３（ａ）　に示す固定解除側に引き起こしてからでないと脱抜は出来ない。ロックレバー３９を固定解除側に引き起こすと、この引き起こしに連動して電源受給スイッチＳＷ６７が開路し、負荷部電気回路６８が駆動電流受給路７１−１から切り離される。
【００６２】
このように電源受給コネクタ３８から負荷部が切り離された状態で、次に部品供給装置３５が部品搭載装置５０から取り外されることによって電源供給コネクタ５３と電源受給コネクタ３８が接続から離脱するので、たとえ両コネクタ間に駆動電流ａが印加されていたとしても、大きな負荷電流が流れていないので、両コネクタの給電・受給端子間に、開放時のサージ電圧によるスパークは発生しない。
【００６３】
本例では、更に、部品搭載装置５０の図４（ｂ）　に示す制御部５９は、突入電流抑止用の抵抗Ｒ２の両端での電圧を常時検出している。制御部５９は、上記のように電源受給スイッチＳＷ６７が開路して、更に部品供給装置３５が部品搭載装置５０から取り外されたことにより駆動電流ａの流れが停止し、抵抗Ｒ２の両端での電圧差が零となったことを検出することにより電源供給コネクタ５３から電源受給コネクタ３８が離脱したことを認識し、この認識に基づいて、電源供給スイッチ５８を開路させ、電源供給端子５５への駆動電流の印加を遮断させる。
【００６４】
これにより、電流制限抵抗Ｒ１を流れる微弱電流ｂのみが電源供給端子５５へ印加されることになり、たとえ接続を解除された電源供給コネクタ５３の端子が外部に露出したままであっても、この端子に、取り付けネジ等の部品や金属性部材などが落下して接触したり、生産従事者が誤って作業中の工具等の金属性部材を接触させたりしても、端子には微弱電流ｂしか流れていないので、このような接触によって他の装置に悪影響を及ぼすような不具合は発生しない。
【００６５】
【発明の効果】
以上説明したように、本発明によれば、電源供給側のコネクタ開放時には給電端子に微弱電流のみを印加し、電源受給側のコネクタが接続されて微弱電流を検出し、この検出による駆動電流要求信号によって初めて駆動電流を給電端子を介して電源受給側のコネクタに供給するので、開放時に端子が外部に露出している電源供給側のコネクタに、取り付けネジ等の部品や金属性部材などが落下して接触したり、生産従事者が誤って作業中の工具等の金属性部材を接触させたりしても、端子には微弱電流しか流れていないので、このような接触が起こっても他の装置に悪影響を及ぼすような不具合が発生しなくなり、作業環境が向上する。
【００６６】
また、部品供給装置を部品搭載装置に装着するだけで、電源供給コネクタの接続が自動的に行われて部品搭載装置から部品供給装置への駆動電源の供給が開始されるので、部品供給装置の取り付け取り外しの際に生産従事者が部品供給装置の電源スイッチを操作する手数を無くなって面倒がなく、これにより作業能率が向上する。

[0002]
[Prior art]

Description of the Related Art Conventionally, a component mounting apparatus that automatically mounts chip-shaped electronic components at predetermined positions on a printed circuit board in a board unit manufacturing line, and a tape cassette type component that supplies the electronic components to the component mounting apparatus, for example. There is a feeding device.
[0003]
FIG. 5A is an external perspective view of the component mounting apparatus, and FIG. 5B is a perspective view schematically showing an internal configuration of the component mounting apparatus by removing upper and lower protective covers. As shown in FIG. 1A, a component mounting apparatus 1 includes a monitor device 2 composed of a CRT display before and after on a ceiling cover, and an alarm lamp 3 for notifying the operation state on the left and right on the ceiling cover, respectively. It has. On the front and rear surfaces of the upper protective cover 4, there are provided small display input panels 5 each comprising a liquid crystal display and a touch-type input device and capable of inputting various instructions by an external operation. (The display input panel 5 at the rear, which is obliquely upward in the figure, is shaded and cannot be seen).
[0004]
On the lower base 6, a pair of fixed and movable parallel board guide rails 7 are provided at the center in the transport direction (X-axis) of a printed board (hereinafter simply referred to as a board) 8 shown in FIG. Direction, from the lower left to the upper right in the figure). Although not visible in the drawing, a loop-shaped transport belt (conveyor belt) is disposed in contact with the lower portions of these board guide rails 7 so as to be able to run.
[0005]
The conveyor belt is driven by a belt drive motor (not shown) to move the belt side portions each having a width of several millimeters from below the substrate guide rail 7 to the substrate transport path, travels in the substrate transport direction, and moves on both sides of the rear surface of the substrate 8. The substrate 8 before mounting components is loaded into the apparatus main body from the upstream side of the line while supporting the components from below, and the substrate 8 on which components are mounted is sequentially transported to the downstream side of the line. Two substrates 8 are always loaded into the component mounting apparatus 1, are positioned, and are fixed until the mounting of the electronic components is completed.
[0006]
A component supply stage 9 is formed before and after the base 6 (the rear component supply stage 9 which is obliquely upward and leftward is not visible in the figure (a). The illustration is omitted in b)). In the component supply stage 9, a large number of 50 to 70 tape cassette type electronic component supply devices (hereinafter, simply referred to as component supply devices) 11 are arranged. In addition, an imaging camera 10 is arranged near the component supply stage 9 inside the apparatus.
[0007]
Above the base 6, two X-axis rails 12 and a Y-axis slidably supported on the X-axis rails 12 in the X-axis direction (from diagonally lower left to upper diagonally right in the figure). Rails 13 are arranged on the left and right, respectively, and two work head support towers 14 are suspended on each Y-axis rail 13 so as to be slidable in the Y-axis direction (from the lower right to the upper left in the figure). Have been. That is, a total of four work head support towers 14 are arranged in the component mounting apparatus 1 shown here.
[0008]
In the example shown in the figure, two work heads 15 are arranged on each work head support tower 14 so as to be able to move up and down vertically (Z direction) and to be rotatable in a 360 degree direction (referred to as θ direction). That is, a total of eight work heads 15 are arranged in the component mounting apparatus 1, and each work head 15 is moved in the X-axis direction by the Y-axis rail 13 and is moved in the Y-axis direction by the work head support tower 14. , The movement in the Z-axis direction by the work head 15 itself, and the rotation in the θ direction, the position in the front-rear, left-right, up-down, and 360-degree directions can be freely controlled. These work heads 15 suction a predetermined electronic component supplied from the component supply device 11 by a suction nozzle, and mount the sucked electronic component at a predetermined mounting position on the substrate 8.
[0009]
Although not particularly shown, a board surface imaging device for confirming the mounting position of the electronic component on the board 8 is arranged in the work head support tower 14 in the vicinity of the work head 15. Although not particularly shown, a substrate positioning device, a substrate fixing mechanism for fixing the substrate between the two substrate guide rails 7, a control device for controlling each part, and a connector to be described later are provided inside the base 6. A power supply controller for supplying power is provided.
[0010]
FIG. 6 is a perspective view showing only one component supply device disposed on the component supply stage of the component mounting device in detail. As shown in the figure, the component supply stage 9 is provided with a number of mounting and fixing holes 16 at the front and rear, and the component supply device 11 is fixedly disposed on the component supply stage 9 by these mounting and fixing holes 16. In the component supply device 11, a reel 17 around which a component tape containing electronic components is wound is held by a reel holding unit.
[0011]
In the component mounting apparatus 1, first, in the component supply device 11 fixedly disposed on the component supply stage 9, the component tape of the reel 17 is pulled out to the component supply port 18, and the component tape is transferred to the top tape 19 and the storage tape 21. The separated electronic components housed in the housing tape 21 are exposed at the component supply port 18. 5A and 5B, the work head 15 of the component mounting apparatus 1 shown in FIGS. 5A and 5B picks up the picked-up electronic component by a suction nozzle, and the picked-up electronic component is image-recognized by the imaging camera 10. The position (posture) of the suction state is corrected, and the electronic component is mounted on the substrate 8.
[0012]
The separated top tape 19 is taken up by a take-up reel 22, and the empty storage tape 21 that has been supplied with the electronic components falls freely below the component supply stage 9 and is deposited.
Usually, 50 to 70 component supply devices 11 are attached to the component supply stage 9, depending on the size of the component mounting device 1 and the size of the supplied electronic components. That is, when the front and rear component supply stages 9 are combined, 100 to 140 component supply devices 11 are arranged in one component mounting device 1.
[0013]
In general, the component supply device 11 has the smallest component tape having a width of 8 mm, and the largest component storage device 11 accommodates a component tape having a width of 50 mm. The attachment fixing hole 16 of the component supply stage 9 is formed so that the component supply devices 11 accommodating the smallest component tape having a width of 8 mm can be arranged side by side.
[0014]
Conventionally, in order to supply the electronic component to the above-described component supply port 18 of the component supply device 11, the latch lever of the latch wheel of the component supply device 11 for intermittently feeding out the component tape is operated by the operation of the component mounting device 1. The electronic component is exposed by pushing in the component tape by pushing it out with the protrusion provided on the head support tower 14 and rotating the take-up reel 22 to forcibly peel off the top tape 19 from the accommodating tape 21. To the component supply port 18.
[0015]
However, in this case, the work head supporting tower 14 of the component mounting apparatus 1, whose primary purpose is to adsorb electronic components and mount them on the substrate, is to push the latch lever with the projection, which is a time required to perform the work away from the purpose of the main body. This increases the overall work time required for electronic components to be sucked and mounted on the board, and in the current trend to speed up component mounting work, improving work efficiency. This is a component supply system having a problem of obstructing the operation.
[0016]
Further, when the width of the component tape is as large as 50 mm, several push operations are required to push out the large component tape by pushing the latch lever with the projection of the work head support tower 14, and the original purpose is further increased. Work efficiency is reduced due to time taken for outside operations.
[0017]
Therefore, a motor has been put to practical use in which a motor is provided on the side of the component supply device 11 and the motor is used to drive the feeding of the component tape and the rotation of the take-up reel 22. In this case, since it is not practical to have a power supply on the component supply device 11 side, the power supply of the component mounting device 1 is used, and as shown in FIG. A number of power supply connectors 23 are provided, and a power supply connector 24 of the component supply device 11 is connected to the power supply connector 23.
[0018]
Each of the connectors has a power supply terminal and a signal line terminal. After the connectors are connected, power is supplied from the power supply of the component mounting apparatus 1 to the component supply apparatus 11 via the power supply terminal, and the power of the component mounting apparatus is connected via the signal line terminal. Various operations of the component supply device 11 are controlled by the control unit.
[0019]
[Problems to be solved by the invention]
By the way, when the component supply device 11 is mounted on the component supply stage 9 of the component mounting device 1, the power supply connector 23 is connected to the power supply connector 24 while the power switch is turned on, or the component supply device 11 is connected to the component mounting device. If the power supply connector 24 is disconnected from the power supply connector 23 while the power switch is turned on when detaching the component supply stage 9 from the first component supply stage 9, discharge due to a surge voltage often occurs between the power supply terminals of the connector.
[0020]
In this way, when a discharge occurs, the arc of the discharge is extremely hot, so that the metal contact forming the power supply terminal is melted and damaged, thereby shortening the life of the metal contact and noise due to the discharge. This is not preferable because it has a problem such as causing adverse effects on other devices which share the same power supply and are still operating.
[0021]
In addition, the component supply stage 9 is not always closed by the component supply device 11, and when a component supply device of another type is connected, or because of the specification of a board unit to be manufactured, so many component supply stages are not provided. In a case where the device 11 is not required, an empty seat of the component supply device 11 is formed on the component supply stage 9. The power supply connector 23 formed on the lower side surface of the vacant seat of the component supply stage 9 has its terminals exposed because the power supply connector 24 of the component supply device 11 is not connected. The power supply current is always applied as in the case of the commercial power outlets inside.
[0022]
Therefore, parts such as mounting screws, metallic members, etc., fall and come in contact with the exposed terminals of the power supply connector 23 as described above, When the members are brought into contact with each other, a short circuit occurs between the terminals of the power supply connector 23. In this case as well, a temporary decrease in the power supply voltage or generation of noise may occur in other component supply devices sharing the same power supply. And other problems.
[0023]
Conventionally, a power switch is disposed at an appropriate position of the component supply device 11, the component supply device 11 is attached to the component supply stage 9, a power supply connector 24 is connected to the power supply connector 23, and then the power switch is turned on. When removing the component supply device 11 from the component supply stage 9, there is no other method than to solve the above problem by turning off the power switch before disconnecting the power supply connector 24 from the power supply connector 23.
[0024]
However, in this method, there is a complaint that it is troublesome to operate the power switch without error in the narrow gap of the component supply devices 11 that are arranged at many small intervals.
In addition, the power supply connector 23 formed on the side surface of the component supply stage 9 is directly below the reel holding unit that holds the reel 17 that protrudes outward from the component supply device 11 mounted on the component supply stage 9. Each time the power supply connector 24 of the component supply device 11 is connected to the power supply connector 23, the production worker bends down or leans down, and looks into the lower part of the reel holding unit to look at the power supply connector 23. The work method of connecting the power receiving connector 24 while confirming the position of the power receiving connector 24 is adopted. This is a troublesome and labor-intensive operation, and there is a problem that efficiency is reduced.
[0025]

When the mounting is completed, the power supply receiving connector 38 is automatically connected to a power supply connector provided on the component supply stage of the component mounting apparatus as described later, and the rotation of the lock lever 39 as an operation mechanism is performed. The power supply switch, which will be described later, of the component supply device 35 that is fixed to the component supply stage by the interlocking lock fitting 41 and that is interlocked with the rotation of the lock lever 39 is closed. The state of the lock lever 39 and the state of the lock fitting 41 shown in the figure show the state when the component supply device 35 is mounted and fixed on the component supply stage, respectively.
[0041]
The component supply device 35 includes a reel holding portion 42 at a rear end portion (right end portion in the drawing), and the reel holding portion 42 can detachably hold a reel 43 on which a component tape is wound. The component tape pulled out from the reel 43 passes through a tape transport path 44 inside the device, passes under a tape pressing member 45 which also serves as a guide to the tape and prevents floating, and is drawn out to a component supply port 46. In the component tape drawn out to the component supply port 46, the upper and lower two tapes of the top tape and the housing tape are peeled off, and the electronic components are exposed on the lower housing tape. The exposed electronic component is sucked and taken out by the suction nozzle at the tip of the work head of the component mounting apparatus.
[0042]
The upper top tape that has been peeled up and down is collected in a tape collection container 47, and the lower accommodation tape passes through a discharge path in the main body of the component supply device 35, and moves outward and downward as indicated by arrow A in the figure. Fall and accumulate.
FIGS. 3A and 3B are schematic diagrams illustrating a mounting method and an electrical connection method when mounting the component supply device 35 on a component supply stage of a component mounting device. 2A and 2B, the same components as those shown in FIG. 2 are denoted by the same reference numerals as those in FIG.
[0043]
First, when the component supply device 35 is mounted on the component mounting device, the lock lever 39 provided on the rear end (right end in the figure) of the component supply device 35 is supported by a support pin as shown in FIG. With the fulcrum 48 as a fulcrum, as shown by an arrow B in the figure, the lock fitting 41 is pulled upward and rearward (upper right in the figure) and rotated clockwise in the figure. From the fixed state, it is rotated upward in the front upper direction (upper left direction in FIG. 3A), that is, clockwise in FIG. Similarly, the lock detection switch 49 is opened in conjunction with the clockwise rotation of the lock lever 39, and a drive current receiving path, which will be described in detail later, is shut off in advance.
[0044]
As shown in FIG. 3A, an engagement groove 52 corresponding to the engagement rail 37 of the component supply device 35 is provided on the component supply stage 51 of the component mounting device 50 for each mounting position of the component supply device 35. A power supply connector 53 is provided on a lower side surface of the engagement groove 52.
[0045]
As described above, since the lock fitting 41 that has been pivoted upward and upward and lifted up has opened the entrance path of the engagement rail 37 into the engagement groove 52, the worker can use the tip of the engagement rail 37. Can be easily inserted into the front end portion (right end portion in the figure) of the engagement groove 52. Then, the worker directly inserts the engaging rail 37 into the engaging groove 52 as shown in FIG. 7A, and then reaches the final position as shown in FIG. Press down. Thus, the power supply connector 38 is automatically connected to the power supply connector 53.
[0046]
Thereafter, as shown in FIG. 3 (b), the worker turns the lock lever 39 in the counterclockwise direction to fall it down, and turns the lock fitting 41 interlocked thereto in the counterclockwise direction. . As a result, the hook-shaped tip of the lock fitting 41 wraps around the lower surface so as to grip the end of the component supply stage 51, locks the component supply stage 51, and the component supply device 35 connects to the component supply stage 51. Fixed. At the same time, the lock detection switch 49 is closed in conjunction with the rotation of the lock lever 39 in the counterclockwise direction, and a drive current receiving path, which will be described in detail later, is made conductive.
[0047]
FIG. 4A is a circuit block diagram of the power supply connector 53 and the related circuit block, and a power supply connector 38 and a circuit block diagram of the related connector. FIG. 4B is a circuit block diagram of the power supply connector 53. FIG. 3 is an internal circuit diagram of a power control unit of FIG.
As shown in FIG. 4A, the component mounting apparatus 50 includes a power supply 54, a power supply connector 53 having at least a power supply terminal 55 and a signal transmission / reception terminal 56 (56-1, 56-2), and a power supply 54. A power control unit 57 is provided between the power supply terminal 55 and the power supply terminal 55. As shown in FIG. 2B, the power supply control unit 57 includes a current limiting resistor R1 and a power supply switch 58 connected in parallel between the power supply 54 and the power supply terminal 55, and opens and closes the power supply switch 58. And a control unit 59 as power control means for controlling the power supply.
[0048]
The power supply switch 58 is, for example, a switching FET (field effect transistor), and is closed when a switch drive voltage is applied to the base by the control unit 59 so that the drive current a is supplied between the power supply 54 and the power supply terminal 55. When the switch is turned on and the application of the switch drive voltage is released, the circuit is opened and the drive current a between the power supply 54 and the power supply terminal 55 is cut off.
[0049]
On the other hand, the current limiting resistor R1 is a resistor circuit having a large resistance value of, for example, several tens of ohms. When the power supply switch 58 is opened and the supply of the drive current a to the power supply terminal 55 is interrupted, The limiting resistor R1 passes the weak current b and supplies the weak current b to the power supply terminal 55.
[0050]
When the power supply connector 53 is not connected to the external power supply receiving connector 38, the control unit 59 opens the power supply switch 58 to cut off the drive current a from the power supply 54 to the power supply terminal 55, and When the connector 53 is connected to the power receiving connector 38, the power supply switch 58 is closed so that the power supply switch 58 is controlled so that the drive current a flows from the power supply 54 to the power supply terminal 55.
[0051]
The connection between the power supply connector 53 and the power supply connector 38 for controlling the power supply switch 58 to be closed by the control unit 59 is detected after the power supply connector 53 is connected to the power supply connector 53. A signal detection unit 61 as a signal detection unit detects a drive current request signal c input from the connector 38 via the signal transmission / reception terminal 56-1, and the signal detection unit 61 converts the detected drive current request signal c to a control unit. It is detected by notifying 59.
[0052]
The transmission and reception of control signals and other signals after the power supply connector 53 is connected to the power supply connector 53 are performed via the signal transmission / reception terminal 56-2. The control unit 25 shown in FIG. 1 on the component mounting apparatus main body side is connected via an F (interface) circuit 62. The drive current request signal c detected by the signal detection unit 61 is notified to the control unit 25 as a connector connection completion signal d. Thus, the control unit 25 starts controlling the component supply device 35.
[0053]
The power control unit 57, signal detection unit 61, I / F (interface) circuit 62, and grounding circuit 63 shown in FIG. 4A form the connector unit 29 shown in FIG. A resistor R2 shown in FIG. 3B is a resistor circuit having a very small resistance value of, for example, about 0.02 Ω, and is provided to suppress an inrush current of the power supply switch 58 at the initial closing of the circuit.
[0054]
On the other hand, as shown in FIG. 4A, the component supply device 35 includes a power receiving connector 38 having at least a power receiving terminal 64 and a signal transmitting / receiving terminal 65 (65-1, 65-2), and a power receiving connector 38. A lock lever 39 as an operation mechanism for freely connecting or disconnecting an external power supply connector 53 to be connected to the power supply connector 38, a voltage detection unit 66 as weak current detection and drive current request means, A power supply switch SW67 that opens and closes in conjunction with the operation of the lock lever 39 and a load electric circuit 68 are provided.
[0055]
The power receiving switch SW67 is, for example, a micro switch, and is not particularly shown. For example, the lock lever 39 protrudes from the fulcrum 48 shown in FIGS. The switch is pushed and closed by an interlocking lever formed integrally with the lever 39, and the pushing is released to open the switch.
[0056]
A voltage detecting section 66 is provided between the power receiving switch SW67 and the power receiving terminal 64 and between the signal transmitting and receiving terminal 65-1 and the signal transmitting / receiving terminal 65-1. When the power supply connector 38 is connected to the power supply connector 53, the weak current b flowing through the resistor R1 shown in FIG. The drive current is supplied to the drive current receiving path 71-1 of the component supply device 35 via the power supply terminal 64 of the power supply 38.
[0057]
The drive current receiving path 71-1 is a circuit connecting the power receiving terminal 64 and the input terminal of the power receiving switch SW67, and a voltage detecting unit 66 is provided between a branch point on the way and the signal transmitting / receiving terminal 65-1. Are connected in series. The voltage detection unit 66 detects a weak current b flowing from the branch point, and sends a drive current request signal c based on the detected weak current b to the signal transmission / reception terminal 65-1 and the signal transmission / reception of the power supply connector 53. The signal is transmitted to the signal detector 61 of the component mounting apparatus 50 via the terminal 56-1.
[0058]
Thus, as described above, in the component mounting apparatus 50, the signal detection unit 61 detects the drive current request signal c, and notifies the control unit 59 of the drive current request signal c. The circuit is closed, and the drive current a from the power supply 54 is supplied to the drive current receiving path 71-1 of the component supply device 35. Thereafter, the lock lever 39 is operated to the fixed side shown in FIG. 3B, and the power receiving switch SW67 is closed in conjunction with this operation. As a result, the drive current a flows from the drive current receiving path 71-1 to the drive current receiving path 71-2, and the drive current a is supplied to the load electrical circuit 68 of the component supply device 35.
[0059]
After the power supply connector 38 is connected to the power supply connector 53, transmission and reception of control signals and other signals are performed via a signal transmission / reception terminal 65-2. The load electric circuit 68 of the component supply device 35 is connected via the / F circuit 69.
[0060]
As described above, before the load electrical circuit 68 of the component supply device 35 is connected to the power receiving terminal 64 by closing the power receiving switch SW67, that is, the load is not connected to the power receiving terminal 64 of the power receiving connector 38. In this state, the power supply connector 38 is connected to the power supply connector 53, so that no contact spark or the like occurs between the power supply / reception terminals of both connectors at the time of connection.
[0061]
The connection between the power supply connector 38 and the power supply connector 53 is released when the component supply device 35 is detached from the component mounting device 50. In order to remove the component supply device 35 from the component mounting device 50, the lock lever 39 must first be raised to the unlocking side shown in FIG. When the lock lever 39 is raised to the unlocking side, the power receiving switch SW67 is opened in conjunction with the lifting, and the load electric circuit 68 is disconnected from the drive current receiving path 71-1.
[0062]
With the load section disconnected from the power receiving connector 38 in this manner, the power supply connector 53 and the power receiving connector 38 are disconnected from the connection by subsequently removing the component supply device 35 from the component mounting device 50. Even if the drive current a is applied between the two connectors, no spark is generated between the power supply / reception terminals of the two connectors due to the surge voltage at the time of opening because no large load current flows.
[0063]
In this example, the control unit 59 of the component mounting apparatus 50 shown in FIG. 4B always detects the voltage across the inrush current suppressing resistor R2. The control unit 59 determines that the flow of the drive current a is stopped by the power supply switch SW67 being opened as described above and the component supply device 35 being further removed from the component mounting device 50, and the voltage at both ends of the resistor R2. By detecting that the difference has become zero, it is recognized that the power supply connector 38 has been detached from the power supply connector 53, and based on this recognition, the power supply switch 58 is opened and the drive to the power supply terminal 55 is performed. Cut off the application of current.
[0064]
As a result, only the weak current b flowing through the current limiting resistor R1 is applied to the power supply terminal 55, and even if the disconnected terminal of the power supply connector 53 remains exposed to the outside, Even if components such as mounting screws or metallic members fall into contact with the terminal, or if a production worker accidentally contacts a metallic member such as a tool that is being worked on, the terminal may have a weak current b. However, such a contact does not cause a problem that adversely affects other devices.
[0065]
【The invention's effect】
As described above, according to the present invention, when the connector on the power supply side is opened, only a weak current is applied to the power supply terminal, the connector on the power supply side is connected, and the weak current is detected. Since the drive current is supplied to the power receiving side connector via the power supply terminal for the first time by the signal, components such as mounting screws and metal members fall into the power supply side connector whose terminal is exposed to the outside when opened. Contact, or if a production worker accidentally contacts a metal member such as a tool that is being worked on, only weak current flows through the terminal. A trouble that adversely affects the device does not occur, and the working environment is improved.
[0066]
Also, simply by attaching the component supply device to the component mounting device, the power supply connector is automatically connected and the drive power supply from the component mounting device to the component supply device is started. This eliminates the need for the production worker to operate the power supply switch of the component supply device when mounting and dismounting the device, thereby reducing the trouble and improving the work efficiency.
