<p>A robotic pick up head for use in picking up electrical connectors (25 and 27) having top actuated rivets (176) and being of different lengths, placing them on a circuit board (19) and setting the rivets (176) to secure the connectors (25 or 27) to the board (19), comprises a body (28) having a top plate (30) for connection to the Z axis shaft (18) of a pick and place robot (2). Opposed piston and cylinder drive units (70 and 72) in the body (28) drive a toggle linkage (50, 54) to drive plungers (142) of riveting tools (26), first to cause the tools (26) to grip the rivets (176) when a connector (25 or 27) is to be picked up and then to set the rivets (176) when they have been inserted into holes (H) in the board (19), to secure the connector thereto. The riveting tools (26) are carried by tool holders (90 and 96) one of which is slidable along a rail (88) on the body (28), by a further piston and cylinder drive unit (103), between two end positions to adjust the spacing between the riveting tools (26) for connector length.</p> |
