Abstract
Description
この加工装置であれば、加工テーブル及び移載テーブルの配列方向に沿って延びる共通のトランスファ軸により第1保持機構及び第2保持機構を移動させる構成とし、加工用移動機構により加工機構を水平面においてトランスファ軸に沿った第1方向及び当該第1方向に直交する第2方向それぞれに移動させるので、加工テーブルを第1方向及び第2方向に移動させることなく、加工対象物を加工することができる。このため、加工テーブルをボールねじ機構により移動させることなく、ボールねじ機構を保護するための蛇腹部材及び当該蛇腹部材を保護するためのカバー部材を不要にすることができる。その結果、加工装置の装置構成を簡素化することができる。また、加工テーブルが水平面上において第1方向及び第2方向に移動しない構成となるので、加工テーブルの移動スペース及びその周辺の無駄なスペースを削減することができ、加工装置のフットプリントを低減することができる。
特に本発明では、加工送り方向の前側から加工機構に加工液を噴射する構成において、加工機構に対して加工送り方向の後側に、加工テーブルの上面よりも下側の位置から上方を覆う加工液飛散防止機構を設けているので、加工液の飛散を防止することができる。
加工機構による加工対象物の加工時にシャッタ部材が移動すると、加工液の飛散を確実に防止できない可能性がある。この問題を解決するためには、加工装置は、前記加工機構による前記加工対象物の加工時において前記シャッタ部材を固定する固定部を有していることが望ましい。
ここで、前記固定部は、前記複数の加工テーブルそれぞれに対応して設けられていることが望ましい。この構成であれば、蛇腹部材を1つの加工テーブルに対応した長さにすることができ、縮んだ状態の蛇腹部材の寸法を小さくすることができる。また、各加工テーブルに応じてシャッタ部材を固定し、1つの加工テーブルを蛇腹部材で覆う構成にすることができ、加工していない加工テーブルに対して加工前の加工対象物を搬入することができるし、加工後の加工対象物を搬出することができる等の処理能力を上げることができる。
この構成であれば、シャッタ部材を移動させる移動機構を別途設ける必要がなく、シャッタ部材を移動させる構成を簡略化することができる。
このようにX方向に沿って設けられる一対のX方向ガイドレールが加工テーブルを挟んで設けられるので、一対のX方向ガイドレールのピッチ(間隔)を大きくすることができる。その結果、X方向ガイドレール同士の上下方向の位置ずれが加工に与える影響を小さくすることができる。つまり、加工機構(例えばブレードなどの回転工具)と加工テーブルの直交度のズレを小さくすることができ、加工精度を向上させることができる。また、X方向ガイドレールに従来よりも低スペックのものを用いることができる。
以下に、本発明に係る加工装置の一実施形態について、図面を参照して説明する。なお、以下に示すいずれの図についても、わかりやすくするために、適宜省略し又は誇張して模式的に描かれている。同一の構成要素については、同一の符号を付して説明を適宜省略する。
本実施形態の加工装置100は、加工対象物である封止済基板Wを切断することによって、複数の製品Pに個片化する切断装置である。
2つの切断用テーブル2A、2Bは、X方向、Y方向及びZ方向に固定して設けられている。なお、切断用テーブル2Aは、切断用テーブル2Aの下に設けられた回転機構9Aによってθ方向に回転可能である。また、切断用テーブル2Bは、切断用テーブル2Bの下に設けられた回転機構9Bによってθ方向に回転可能である。
第1保持機構3は、図1に示すように、封止済基板Wを基板供給機構11から切断用テーブル2A、2Bに搬送するために封止済基板Wを保持するものである。この第1保持機構3は、図5及び図6に示すように、封止済基板Wを吸着保持するための複数の吸着部311が設けられた吸着ヘッド31と、当該吸着ヘッド31の吸着部311に接続された真空ポンプ(不図示)とを有している。そして、吸着ヘッド31が、後述する搬送用移動機構7などにより所望の位置に移動されることにより、封止済基板Wを基板供給機構11から切断用テーブル2A、2Bに搬送する。
加工機構である切断機構4は、図1、図2及び図3に示すように、ブレード41A、41B及び2つのスピンドル42A、42Bからなる2つの回転工具40を有するものである。2つのスピンドル42A、42Bは、それらの回転軸がY方向に沿うように設けられており、それらに取り付けられるブレード41A、41Bが互いに対向するように配置される(図3参照)。スピンドル42Aのブレード41A及びスピンドル42Bのブレード41Bは、X方向とZ方向とを含む面内において回転することによって各切断用テーブル2A、2Bに保持された封止済基板Wを切断する。なお、本実施形態の切断装置100には、図4に示すように、ブレード41A、41Bによって発生する摩擦熱を抑えるために加工液である切削水を噴射する切削水供給機構(加工液供給機構)12が設けられている。この切削水供給機構12については、後述する。
本実施形態の移載テーブル5は、図1に示すように、後述する検査部13により検査された複数の製品Pが移されるテーブルである。この移載テーブル5は、いわゆるインデックステーブルといわれるものであり、複数の製品Pを各種トレイ21に仕分けする前に、複数の製品Pが一時的に載置される。また、移載テーブル5は、2つの切断用テーブル2A、2Bと水平面上においてX方向に沿って一列に配置される。移載テーブル5に載置された複数の製品Pは、検査部13による検査結果(良品、不良品など)に応じて、仕分け機構20によって各種トレイ21に仕分けされる。
ここで、検査部13は、図1に示すように、切断用テーブル2A、2Bと移載テーブル5との間に設けられ、第2保持機構6に保持された複数の製品Pを検査するものである。本実施形態の検査部13は、製品Pの反対面を検査する第1検査部131と、製品Pの実装面を検査する第2検査部132とを有している。第1検査部131は、反対面を検査するための光学系を有する撮像カメラであり、第2検査部132は、実装面を検査するための光学系を有する撮像カメラである。なお、第1検査部131及び第2検査部132を共通としても良い。
第2保持機構6は、図1に示すように、複数の製品Pを切断用テーブル2A、2Bから反転機構14に搬送するために複数の製品Pを保持するものである。この第2保持機構6は、図8に示すように、複数の製品Pを吸着保持するための複数の吸着部611が設けられた吸着ヘッド61と、当該吸着ヘッド61の吸着部611に接続された真空ポンプ(不図示)とを有している。そして、吸着ヘッド61が、後述する搬送用移動機構7などにより所望の位置に移動されることにより、複数の製品Pを切断用テーブル2A、2Bから保持テーブル141に搬送する。
搬送用移動機構7は、図1に示すように、第1保持機構3を少なくとも基板供給機構11と切断用テーブル2A、2Bとの間で移動させるとともに、第2保持機構6を少なくとも切断用テーブル2A、2Bと保持テーブル141との間で移動させるものである。
切断用移動機構8は、2つのスピンドル42A、42Bそれぞれを、X方向、Y方向及びZ方向の各方向に直線移動させるものである。
上記の切断用移動機構8において支持体812には、図3、図4、図9~図11に示すように、2つのスピンドル32A、32Bを収容するカバー部材15が設けられている。なお、図2においてカバー部材15は省略している。このカバー部材15は、支持体812においてX方向に沿った一方側(加工送り方向SDを向く側)に設けられており、噴射ノズル121から噴射される切削水が周囲に飛び散らないように切断機構4の2つのスピンドル32A、32Bだけでなく切削水供給機構12の噴射ノズル121を収容するものである。
また、本実施形態の切断装置100は、図1に示すように、封止済基板Wの切断により生じた端材などの加工屑Sを収容する加工屑収容部17をさらに備えている。
また、本発明の切断装置100は、図1及び図5に示すように、切断用テーブル2A、2Bに保持された複数の製品Pの上面側(実装面)をクリーニングする第1クリーニング機構18をさらに備えている。この第1クリーニング機構18は、切断用テーブル2A、2Bに保持された複数の製品Pの上面に洗浄液及び/又は圧縮空気を噴射する噴射ノズル18a(図5参照)によって、製品Pの上面側をクリーニングするものである。
さらに、本発明の切断装置100は、図1に示すように、第2保持機構6に保持された複数の製品Pの下面側(反対面)をクリーニングする第2クリーニング機構19をさらに備えている。この第2クリーニング機構19は、切断用テーブル2Bと検査部13との間に設けられており、第2保持機構6に保持された複数の製品Pの下面に洗浄液及び/又は圧縮空気を噴射することによって、製品Pの下面側をクリーニングする。つまり、第2保持機構6がトランスファ軸71に沿って移動される途中において、第2クリーニング機構19は製品Pの下面側をクリーニングする。
本実施形態では、上述したように、切断機構4の加工送り方向SDは、X方向に沿った一方を向く方向(図3においては紙面上から下に移動する方向、図4においては、紙面右から左に移動する方向)となるように構成されている。
次に、図4の左側の切断用テーブル2Aで封止済基板Wを切断する場合を考えて、切削水飛散防止機構24の動作について、図10~図14を参照して説明する。
次に、切断装置100の動作の一例を説明する。図15には、切断装置10の動作における第1保持機構3の移動経路、及び、第2保持機構6の移動経路を示している。なお、本実施形態においては、切断装置100の動作、例えば封止済基板Wの搬送、封止済基板Wの切断、切削水飛散防止機構24の動作、製品Pの検査など、すべての動作や制御は制御部CTL(図1参照)により行われる。
本実施形態の切断装置100によれば、切断用テーブル2A、2B及び移載テーブル5の配列方向に沿って延びる共通のトランスファ軸71により第1保持機構3及び第2保持機構6を移動させる構成とし、切断用移動機構8により切断機構4を水平面においてトランスファ軸71に沿ったX方向及びX方向に直交するY方向それぞれに移動させるので、切断用テーブル2A、2BをX方向及びY方向に移動させることなく、封止済基板Wを加工することができる。このため、切断用テーブル2A、2Bをボールねじ機構により移動させることなく、ボールねじ機構を保護するための蛇腹部材及び当該蛇腹部材を保護するためのカバー部材を不要にすることができる。その結果、切断装置100の装置構成を簡素化することができる。また、切断用テーブル2A、2BをX方向及びY方向に移動しない構成にすることができ、切断装置100のフットプリントを低減することができる。
