Application: Automated teach apparatus for robotic systems and method therefor (Patent ID: US20230343626A1)
The patent filed by Azenta Inc. describes an automatic teaching system for a substrate processing apparatus. The system includes a frame with a workpiece load station, a robot transport with a movable arm and end effector, and a machine vision system with fixed and movable imaging sensors. The method involves providing a load jig, imaging targets with the machine vision system, and justifying the movable imaging sensor in a predetermined position relative to the end effector reference location.
The method further includes a controller to move the transport arm, resolve offsets between reference locations, and align targets for teaching positions. The load jig is configured as a mock substrate carrier, and the fixed imaging sensor is positioned to image arm targets for offset resolution. The system allows for precise teaching of the substrate processing apparatus by utilizing multiple imaging sensors, teach positions, and offset resolution techniques to ensure accurate alignment and operation of the system.
