Abstract
A sensor or switch mechanism is connected to a gripper mechanism and uses a pivotal cam link connected to the driving mechanism of the gripper. A cam slot in the cam link is configured to convert linear reciprocal motion of the driving mechanism of the gripper to amplified rotational motion of the pivotal cam link. A target on the cam link and a stationary sensor positioned proximate to an arc described by the target on rotation of the cam link allows the sensor or switch mechanism to distinguish between the gripper properly gripping a single workpiece and the gripper improperly gripping no workpiece and/or two or more workpieces.
