YC)Tのロボット座標系で表した座標(XC, YC)R Tである。
<ロボット教示の手順>
ロボット10、アライナ20、基板2及びフープ30を使用した教示の手順について、図6を参照しつつ説明する。なお、図6は、アライナ20におけるロボット10や基板2の中心位置等の教示点や動作点を示している。
フープ30内に、基板2の中心が正確になるように配置して収納する。
フープ30内の取出し位置として予め暫定的に設定したフープ位置P0(以下「仮設定されたフープ位置」という。)に基づき、ロボット10により基板2を、フープ30から取り出す。ここで、P0は、基板2を取り出すための仮設定されたフープ位置であるため、ロボット10により基板2の中心位置の把握はなされていない。
回転テーブル21の基準位置(回転テーブルの回転中心)として予め暫定的に設定したアライナ位置Oac(以下、「仮設定されたアライナ位置」という。)に基づき、ロボット10により基板2を、アライナ20の回転テーブル21に搬送し載置する。以下、仮設定されたアライナ位置に基づき回転テーブル21の上に載置された基板2の中心位置を「第一の基板載置位置」といい、A1とし、ロボット座標系における座標を(X1, Y1)Tであらわす。
前記<アライナ>において説明した方法により、すなわち回転テーブル21を回転させてセンサ部23により最長距離Lmax及び/又は最短距離Lminに基づいて、第一の基板載置位置A1におけるトータルオフセット1(Ot1)の大きさ及びその方向(角度)を測定する。
回転テーブル21を回転させて基板2の中心位置を第一の基板載置位置A1に戻す。
回転テーブル21上の基板2をロボットハンド16で把持して、ロボット10を使用して、ロボット座標系において、x軸と平行な方向に予め設定した距離d移動して回転テーブル21上に載置する。この移動後の基板2の中心位置を第二の基板載置位置A2とし、ロボット座標系における座標を(X2, Y2)Tであらわす。なお、本実施形態では、前記ロボット10による基板2の移動方向をx軸と平行な方向としたのは、以下の式の変形や誘導を簡略化するためであって、原理的ないし数学的には、予め設定する距離dが特定できれば、移動方向は任意の方向であって構わない。
前記<アライナ>において説明した方法により、すなわち回転テーブル21を回転させてセンサ部23により最長距離Lmax及び/又は最短距離Lminに基づいて、第二の基板載置位置A2におけるアライナ座標系原点に対する基板2の中心の位置ずれ(ベクトル)(以下「トータルオフセット2」という。)Ot2の大きさ及び方向を測定する。
基板2をロボット10のハンド16で把持して第一の基板載置位置A1に戻す。したがって、このときの基板2の中心位置はA1である。
仮設定されたアライナ位置(Oac)を通りz線に平行な直線のまわりにハンド16を予め設定した角度αだけ回転する。
角度αの回転が終了したら、基板2を回転テーブル21の上に載置する。このときの基板2の中心位置を第三の基板載置位置A3とし、ロボット座標系における座標を(X3, Y3)Tとする。
前記<アライナ>において説明した方法により、すなわち回転テーブル21を回転させてセンサ部23により最長距離Lmax及び/又は最短距離Lminに基づいて、第三の基板載置位置A3の位置における基板中心位置ずれ(トータルオフセット3)Ot3の大きさ及び方向を測定する。
- 教示用治具等を必要とせずに、教示作業が可能となるため、システムが簡素化できるとともに、制御に際してハンド等の情報が不要となり、制御が容易となる。
