ABSTRACT:
A robot pick-up head for an electrical connector with a hollow rivet at each end, comprises a body for attachment to the Z axis shaft of a robot. In the body are a pair of spring loaded pins, one on each side of the Z axis, and between the pins, is a spring loaded vacuum block. The pins terminate in tapered spigots for insertion into the hollow rivets. When the connector is to be picked up, the spigots are inserted into the rivets with the full force of the robot so that if the rivets are initially canted with respect to the connector, the rivets are straightened. The vacuum block then engages the housing of the connector and is evacuated so that the connector is picked up as the robot shaft rises. The loading springs of the vacuum block are softer than those of the pins so that the connector housing is not damaged when it is engaged by the vacuum block.
