Abstract
An end effector assembly and method for robot-enabled manipulation of round objects automates the gripping, rotationally manipulating, loading, and unloading of round objects, like an ophthalmic substrate, to a coating machine subassembly. A lens wheel carries spring-loaded retention pegs that grip and release the round object. Springs selectively generate tension on the retention pegs, causing retention pegs to articulate radially inward or outward, so as to press the round object to the lens wheel, or release the object. A retention peg actuator selectively engages the springs to generate tension and release tension from springs. A processor regulates articulation of the retention peg actuator. A sensor detects the position of the object, whereby at least one position of the round object triggers the sensor to transmit a signal commanding the retention peg actuator to articulate. A human-machine interface transmits command signals and displays positions of the lens wheel and retention pegs.
