Abstract: A method for detecting positions of wafers includes: rotating a rotation table with a wafer thereon in a first direction at a first speed; detecting a contour of the wafer rotating in the first direction at the first speed to provide contour data; rotating the rotation table in a second direction at a second speed when an aiming feature of the wafer passes the detector in the first direction at the first speed; detecting the contour of the wafer rotating in the second direction at the second speed to provide new contour data; and stopping the rotation of the rotation table and the detection of the wafer according to an accumulation of contour data and corresponding rotation angles, to estimate an eccentric position of the wafer and a position of the aiming feature when the aiming feature passes the detector in the second direction at the second speed.

Abstract: A gripper device includes a base and two gripping assemblies, each including a gripping member, a stand, and an elastic member. The gripping member includes a gripping portion and a supporting portion. The stand is movably disposed to the base and includes a connecter and a supporter. The supporting portion is pivotally connected to the supporter at a position between the gripping portion and the connecter so that the gripping member is pivotable relative to the stand. Two opposite ends of the elastic member are respectively connected to the supporting portion and the connecter. When one of the gripping portions touches an object, the gripping member pivots relative to the corresponding stand. Therefore, gripping a target may not be interrupted by interference objects around the target.

Abstract: A method and an apparatus for detecting positions of wafers. A rotation table, on which the wafer with an aiming feature is disposed, rotates in a direction at a faster speed while a detector detects a periphery of the wafer and provides a controller with a detection result. The rotation table rotates in an opposite direction at a slower speed after the aiming feature passes the detector, while the detector detects the periphery of the wafer and provides the controller with a new detection result. A respective detection result corresponds to a rotation angle. When the aiming feature passes the detector again, the rotation table stops rotating, and the controller computes the eccentric position of the wafer and the position of the aiming feature according to the detection results and their rotation angles. Therefore, the time for detection may decrease.

Abstract: A mechanical end-effector changer includes a first connection unit and a second connection unit. The first connection unit has mounted therein multiple movable members and mating elastic members. Subject to the linking relationship between each movable member and the respective elastic member, the first connection unit and the second connection unit can be automatically connected together or detached from each other, facilitating end-effector change.
