Abstract:
1. A flat workpiece transport apparatus comprising: a movable arm; and an end effector connected to the arm, the end effector having a movable grip for holding a flat workpiece on the end effector, and having a grip actuator operably connected to the movable grip; the grip actuator having more than one actuation members and a resiliently flexible member connecting the more than one actuation members, each actuation member actuating at least one corresponding grip element of the movable grip to capture or release the workpiece; wherein, pivoting movement of one of the more than one actuation members causes flexure and relaxation of the resiliently flexible member, the flexure and relaxation of the resiliently flexible member effects corresponding pivotal movement of at least another of the more than one actuation members for actuation of the at least one corresponding grip element of the at least another of the more than one actuation members reciprocatively between positions for gripping and releasing the flat workpiece, and wherein the resiliently flexible member is sandwiched by substantially rigid portions of the more than one actuation members.
