Apparatus for clinching workpieces to a board

摘要

Apparatus for clinching rivets on electrical connectors to the bottom of a circuit board, comprises a frame in which a shuttle for supporting the board is movable along a rectilinear horizontal path by means of a robot which places the connectors on the board. Two jaw carriages provided with rivet clinching jaws are mounted in the frame beneath the shuttle for movement towards and away from one another by means of cam tracks on the shuttle and cam follower rails on the jaw carriages. The cam tracks are so shaped that the clinching jaws will clinch the rivets where the connectors are placed on the board in longitudinally offset relationship according to the program of the robot. Each jaw carriage has a jaw drive unit thereon which is operated to open and close the jaws according to the robot program.
