Abstract
A pick-up head (20) for a robot (2), comprises a body (28) having a plate (30) for attachment to the Z-axis shaft (18) of the robot (2). Two pick-up arms (34), pivotally attached to the body (2) each carry a riveting tool (26). The tools (26) are driven through a working stroke by a piston and cylinder drive unit (52) on the body (2), against the action of return springs (82). The tools (26) are inserted by the robot (2) lowering the pick-up head (20), into rivets at the ends of the leading electrical connector (25') at a pick-up station (21) and are arranged to be releasably secured to the rivets to allow the robot (2) to transfer the connector (24') to a circuit board (19) and to insert projecting ends of the rivets into holes in the board (10). The drive unit (52) is then actuated to cause the tools (26) to expand the projecting ends of the rivets, the tools (26) are released from the rivets, and the pick-up head (20) is raised by the robot (2). The pick-up arms (34) can be pivoted towards or away from each other and then fixed in a given angular position to allow for connector length.
