Abstract
Description
この加工装置であれば、加工用移動機構により加工機構を水平面において互いに直交する第1方向及び第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、加工テーブルを移動させる移動機構を不要にすることができ、装置構成を簡素化するとともに、フットプリントを低減することができる。
また、加工機構を第2方向に移動可能に支持する支持体の移動方向(第1方向)と、保持部を移動させる保持部移動機構の移動方向(第2方向)とが互いに直交するので、支持体を第1方向に移動させて加工機構を加工具交換機構に近づけるとともに、保持部移動機構が加工具保持部を第2方向に移動させて、加工機構の加工具を交換することができる。このように本発明では、加工機構を移動させる加工用移動機構と加工具交換機構の保持部移動機構とを最適な配置にすることができ、加工装置の装置構成を簡素化するとともに、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、トランスファ軸が第1方向に延びているので、トランスファ軸の延伸方向と保持部移動機構の移動方向とは平面視において互いに直交することになる。また、トランスファ軸と支持体とは平面視において互いに直交するとともに、トランスファ軸の延伸方向と支持体の移動方向とは平面視において互いに平行となる。このような関係により加工用移動機構、加工具交換機構及びトランスファ軸を最適に配置できるようになる。
このとき、前記第1保持機構は、前記加工具をドレッシングするためのドレス部材を保持するドレス部材保持部を有することが望ましい。
この構成であれば、加工対象物を保持する第1保持機構がドレス部材を保持するので、別途ドレス部材保持機構を設ける必要がなく、装置構成を簡素化することができる。
ここで、第1方向に沿って複数の加工テーブルが配置されているので、1つの加工用移動機構により複数の加工用テーブルに加工機構を移動させることができる。その結果、装置構成を簡素化することができる。
この構成において、装置のフットプリントを低減するためには、前記ドレス用テーブルは、前記加工テーブルの間に設けられていることが望ましい。
移動レールにより受取ステージを第2方向に移動させて搬送位置に移動させる構成とすることにより、加工装置のフットプリントを低減することができる。具体的には、移動レールにより受取ステージを第2方向に移動させるので、第1保持機構を移動させるトランスファ軸が平面視において互いに直交することになり、加工装置のフットプリントを低減することができる。
この構成において装置構成を簡素化するためには、前記保持部移動機構は、前記移動レールに沿って移動できることが望ましい。
この構成において装置構成を簡素化するためには、前記ドレス部材収容部は、前記移動レールに沿って移動可能に設けられていることが望ましい。
この場合、前記加工具交換機構は、前記ブレードを吸着して保持する前記加工具保持部である第1吸着部と、前記第1吸着部とは別に設けられ、前記フランジを吸着して保持する第2吸着部とを有し、前記フランジにおける前記第2吸着部に吸着される吸着面は、前記スピンドル部の回転軸に直交する平面であることが望ましい。
この構成であれば、第2吸着部によりフランジを安定して吸着保持することができ、保持部移動機構による第2吸着部の移動時にフランジが位置ずれ又は落下するおそれを低減できる。
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、複数の加工品である製品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。
切断機構4は、図1、図2及び図3に示すように、加工具に相当するブレード41A、41B及び2つのスピンドル部42A、42Bからなる2つの回転工具40を有するものである。2つのスピンドル部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)。スピンドル部42Aのブレード41A及びスピンドル部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3及び図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切削水(加工液)を噴射する噴射ノズル121を有する液体供給機構12が設けられている。この噴射ノズル121は、例えば、後述するZ方向移動部83に支持されている。
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。さらに、移載テーブル5は、Y方向に沿って前後に移動可能であり、仕分け機構20まで移動することができる。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の封止面(パッケージ面)を検査する第1検査部131と、製品Pのリード面を検査する第2検査部132とを有している。第1検査部131は、パッケージ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、リード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から移載テーブル5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又は移載テーブル5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つのスピンドル部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。
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9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、後述するブレードの交換、ドレッシングなど、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。
以下に、基板供給機構11の詳細構成について説明する。
基板収容部111に収容された封止済基板Wを押出機構114のプッシュ部材114aにより押して、封止済基板Wの一部を基板収容部111から搬入用ステージ115A側に出す。そして、封止済基板Wの基板収容部111から出た部分を基板移動部116のクリップ部116aで挟み、クリップ部116aをX方向移動部116bによりX方向に移動させて、封止済基板Wを基板収容部111から引き出して搬入用ステージ115Aに載置する。
本実施形態の切断装置100は、図10及び図15に示すように、ブレード41A、41Bを自動的に交換するブレード交換機構24を有している。具体的にブレード交換機構24は、本実施形態では2つのスピンドル部42A、42Bそれぞれからブレード41A、41Bを交換できるものである。そして、ブレード交換機構24は、取り外したブレード41A、41Bを保持したまま、ブレード収容部25にブレード41A、41Bを収容し、新しいブレード41A、41Bを保持して、スピンドル部42A、42Bに搬送して取り付けるものである。なお、ブレード交換機構24は、加工具交換機構に相当する。
基板収容部111にある封止済基板を、押出機構114及び基板移動部116を用いて、受取ステージ115の搬入用ステージ115Aに受け渡す。
基板収容部111にあるハーフカット予定の封止済基板Wを、押出機構114及び基板移動部116を用いて、受取ステージ115の搬入用ステージ115Aに受け渡す。
本実施形態の切断装置100によれば、切断用移動機構8により切断機構4を水平面において互いに直交する第1方向(X方向)及び第2方向(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を移動させる移動機構を不要にすることができ、装置構成を簡素化するとともに、フットプリントを低減することができる。
