ABSTRACT:
A robot tool changer and overload device has first and second separable plates adapted to be respectively connected to a robot arm and to an end of arm tooling device (EOAT) for the robot; a magnet is connected to one of the plates and a steel insert is connected to the other of the plates for providing a magnetic attraction therebetween for holding the first and second plates together; a pair of frustoconical bearing surfaces are formed on the first and second plates at an angle and a depth to interconnect the plates during normal operation and operative to produce pivotal release movement between the plates when an overload force is applied thereto; a flange on one of the plates is adapted to be removably received within a tool cage to cooperate with structure for applying a pneumatic release force between the first and second plates to allow separation therebetween along a Z axis without imposing an overlaod force on the robot arm.
