Abstract
A pneumatically actuated, electrically controlled electronic component handling apparatus straightens out the leads of an electronic component, positions and orients the component for engagement by an automatic gripper device, and determines the exact orientation of the component for subsequent testing, assembly or insertion of the component in circuit. As a component exits a vibrating delivery chute, a first pneumatic cylinder places a component stop in position to prevent the exit of additional components from the chute. With the discharged component engaged from above by a second pneumatic cylinder actuated pusher, a third pneumatic cylinder raises a component carriage in engagement with a lower portion of the component. The carriage includes a pair of elongated slots therein having enlarged openings for receiving and straightening a respective component lead inserted therein. A fourth pneumatic cylinder then laterally displaces the carriage to a pick-up point where the component is engaged and removed from the carriage by a robotic gripper. Before removal, an optical senser directs a light beam upon the marked component to determine its relative orientation with respect to the gripper to ensure proper subsequent manipulation of the component. Various optical and electrical sensors are employed to control the sequence of pneumatic operations in the component handling apparatus.
