Abstract
Description
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。
さらに、個片化された加工対象物を保持した第2保持機構を収容ボックスに搬送して、当該第2保持機構から個片化された加工対象物を落下させて収容ボックスに収容するので、従来のトレー収容する構成に比べて、収容スペースを小型化することができる。これによっても、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、前記搬送用移動機構は、前記第2保持機構を、前記加工テーブルから前記乾燥テーブルに移動させ、前記乾燥テーブルから前記収容テーブルに移動させることになる。
この構成であれば、X方向に設けられる一対の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Z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、回転工具(例えばブレード)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。

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100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の乾燥、製品Pの掻き落とし動作など、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及び収容ボックス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を個片化することができる。このため、切断用テーブル2A、2Bをボールねじ機構等により移動させることなく、ボールねじ機構等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。
