CONTROL METHOD AND GRIPPER FOR PRECISION MICRO-POSITIONER

摘要

PURPOSE: An air cylinder is mounted to adjust widening of jaws and gripping force, thereby improving accuracy and reducing cost and volume. CONSTITUTION: A gripping device of an accurate position determining device comprises a pair of jaws(15) mounted to a robot wrist portion to grip workpiece(5) and to insert the workpiece into a processing groove(7a) of a lower die(7). An air cylinder(13) is installed between the robot wrist portion and the jaws of right and left side. The air cylinder controls pressure to widen the jaws by repulsive force of the workpiece and the processing groove.
