ABSTRACT:
A plurality of main and sub-chucks are used in a manner wherein the main chucks are used to pick up objects from a first tray, to move the objects to a second tray, and to place them in the second tray in exactly the desired positions. A floating mechanism allows the main chucks to slide from side to side while the sub-chucks are released. The sub-chucks are arranged to grasp a fixed centering structure and to center the main chucks in exactly the required positions for the precision placement of the objects. During the operations wherein the objects are picked up from the first tray, the sub-chucks are released so that during the pickup operation, the main chucks may center on the objects which are being picked up. After the objects are grasped, the sub-chucks are closed to re-center the main chucks in exactly the positions required for accurate placement.
