Abstract

A technique is described whereby a pin insertion tool, used in conjunction with the end-of-arm effector of the IBM 7540 robot or similar robots, allows simultaneous insertion of multiple contact pins into printed circuit boards or back panels. Contact pins, when inserted into printed circuit boards or back panels, require significant insertion force, since the circuit pins are swaged into place. The insertion tool, as shown in the figure, when used in conjunction with the end-of-arm effector of the IBM 7540, provides the required force enabling twenty circuit pins to be inserted simultaneously. The twenty pins 10 are loaded by a separate presentation mechanism into inserter 11, which is connected to connecting rod 12 and held in place by locknut 13 to air cylinder 14.

Pin Insertion Tool for Use As a Robotics End-Of-Arm Effector

A technique is described whereby a pin insertion tool, used in conjunction with the end-of-arm effector of the IBM 7540 robot or similar robots, allows simultaneous insertion of multiple contact pins into printed circuit boards or back panels. Contact pins, when inserted into printed circuit boards or back panels, require significant insertion force, since the circuit pins are swaged into place. The insertion tool, as shown in the figure, when used in conjunction with the end- of-arm effector of the IBM 7540, provides the required force enabling twenty circuit pins to be inserted simultaneously. The twenty pins 10 are loaded by a separate presentation mechanism into inserter 11, which is connected to connecting rod 12 and held in place by locknut 13 to air cylinder 14. Front guide 15 and back guide 16 are provided to assure inserter 11 is accurately positioned and perpendicular to the printed circuit board or back panel. Connecting rod 12 is designed so as to allow compliance between the pneumatic cylinders actuating rods of the end-of-arm effector and inserter 11. Mounting plate 17 and adapter 18 are positioned into the robot arm. The tool provides accuracy of pin placement and the required force, rigidity and stability to enable pneumatic cylinder 14 to function without the need of complex bearings and seals.
