| 摘要 | A method and system for optically inspecting parts are provided wherein the system includes a part transfer subsystem including a transfer mechanism adapted to receive and support a part at a loading station and to transfer the supported part by a split belt conveyor so that the part travels along a first path which extends from the loading station to an inspection station at which the part has a predetermined position and orientation for inspection. An illumination assembly simultaneously illuminates a plurality of exterior side surfaces of the part with a plurality of separate beams of radiation. A telecentric lens and detector assembly forms an optical image of at least a portion of each of the illuminated side surfaces of the part and detects the optical images. A processor processes the detected optical images to obtain a plurality of views of the part which are angularly spaced about the part.In an alternative embodiment the method and system for optically inspecting headed manufactured parts employ an inclined split track to cause the part to traverse an inspection station by gravity feed. The part is inspected for conformity to dimensional and visual standards and sorted under control of a processor based on images of the part obtained from occluded light and reflected light while the part is within the inspection station. | ||||||
