Claim of US Patent No. 10,335,958

1. A robotic end effector quick change coupling apparatus comprising:a robotic manipulator having controllable motion in at least one axis;
a drive motor assembly connected to the robotic manipulator and having a center drive interface;
a coupling component extending from the drive motor assembly and having a magnetic element;
an end effector having a mating coupling component and having a drive connection adapted to removably receive the center drive interface, said mating coupling component concentric with the drive connection and having a mating magnetic element, said magnetic element and mating magnetic element separably engaged by mutual magnetic attraction;
a tool holder incorporating a relief sized to closely receive the profile of the end effector, said tool holder adapted to removably receive and secure said end effector whereby motion of the robotic manipulator in the at least one axis joins or separates the coupling component and the mating coupling component and the robotic manipulator engages or disengages the end effector.
