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。
この構成であれば、トランスファ軸に沿って移動する第1保持機構を加工用移動機構の上方で移動させることができ、第1保持機構が加工用移動機構と物理的に干渉することを防ぐことができる。また、トランスファ軸に沿って移動する第2保持機構を加工用移動機構の上方で移動させることができ、第2保持機構が加工用移動機構と物理的に干渉することを防ぐことができる。
この構成において、前記複数の加工テーブル及び前記移載テーブルは、水平面上において一列に配置されていることが望ましい。
この構成であれば、共通のトランスファ軸に沿って移動する第1保持機構によって、複数の加工テーブルそれぞれに加工対象物を搬送することができる。また、共通のトランスファ軸に沿って移動する第2保持機構によって複数の加工テーブルそれぞれから移載テーブルに加工後の加工対象物を搬送することができる。また、一方の加工テーブルで加工対象物を処理している際に、他方の加工テーブルにおいて搬送などの別の処理を行うことができる。
この加工の制約を解消するためには、前記加工テーブルは、水平面上において回転可能に構成されていることが望ましい。
このように第1方向に沿って設けられる一対の第1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、一対の第1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、第1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、第1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。
この構成において、共通のトランスファ軸を用いて第1クリーニング機構を移動させる構成にして装置構成を簡素化するためには、前記第1クリーニング機構は、前記第1保持機構とともに前記トランスファ軸に沿って移動可能に構成されていることが望ましい。
この構成において、前記ラックアンドピニオン機構は、前記第1保持機構及び前記第2保持機構に共通のカムラックと、前記第1保持機構及び前記第2保持機構それぞれに設けられ、アクチュエータにより回転するピニオンギアとを有することが望ましい。
この構成であれば、共通のカムラックの長さを変更することにより、第1保持機構及び第2保持機構の移動範囲を任意に設定することができる。
ここで、昇降移動機構は、第1保持機構による加工対象物の受け渡しの際に昇降移動するだけでなく、第1保持機構が加工用移動機構に物理的に干渉しないようにすべく昇降移動する。また、水平移動機構により、第1保持機構により加工対象物を加工テーブルに載置する際に加工対象物を加工テーブルに対して第2方向に沿って位置調整することができる。
この構成であれば、案内シュータが加工テーブルを取り囲む上部開口を有するので、加工テーブルから飛散又は落下した加工屑を取りこぼしにくくなり、加工屑の回収率を一層向上することができる。

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方向それぞれに独立して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9及び図10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、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2つのスピンドル32A、32Bだけでなく噴射ノズル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(リード面)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(パッケージ面)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。
次に、切断装置100の動作の一例を説明する。図11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、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。
なお、本発明は前記実施形態に限られるものではない。
