Patent number: 11162906Abstract: A high-speed method and system for inspecting and sorting a stream of unidentified mixed parts are provided. The system includes a pair of inspection stations each of which includes a vision-based robotic subsystem including a robot configured to pick up a self-supporting part and place the part on a fixtureless rotary stage. A second subsystem optically measures a profile and features of the part during part rotation. A processor is operable to compare the profile and features of the part with the profile and corresponding features of stored templates to identify a matching template. A mechanism including a part sorter directs unidentified parts and parts having an unacceptable geometric dimension or defect to a reject part area and directs identified parts having acceptable geometrical dimensions and no significant defects to good part areas.Type: GrantFiled: May 16, 2019Date of Patent: November 2, 2021Assignee: General Inspection, LLCInventors: Michael G.
