摘要： A computer-implemented method of automatically generating inspection templates of a plurality of known good fasteners to identify fasteners at an inspection station is provided. The method includes providing a data entry mechanism to provide content needed to identify a plurality of unidentified mixed fasteners. The method also includes storing the content in a database, extracting the content from the database and creating the inspection templates from the extracted content. Each of the templates including a fastener profile and a set of features. Each of the features includes a range of acceptable values. Each of the templates has a fastener identification code associated therewith.

摘要： A sorting system for inspected parts includes a storage assembly, a conveyance system, and a controller. The storage assembly has a plurality of bins configured to receive and store the inspected parts. The conveyance system is configured to deliver the inspected parts to the storage assembly. The controller programmed to, assign part types to each of the plurality of bins. The controller is further programmed to operate the conveyance system to deliver each of the inspected parts to one of the plurality of bins having a matching part type. The controller is further programmed to, in response to a full condition of the storage assembly, empty the inspected parts from a first the plurality of bins.

摘要： A method and system for optically inspecting a manufactured part at a single inspection station having a measurement axis are provided. The system comprises a fixture assembly which includes a rotatable first fixturing component to support a part in a generally vertical orientation and a rotatable second fixturing component mating with and removably connected to the first fixturing component to transmit torque from the first fixturing component to the second fixturing component. The second fixturing component includes a device for holding the part in a generally horizontal orientation and to permit rotation of the horizontally held part about the measurement axis between first and second predetermined angular positions about the axis. The system also comprises an actuator assembly, a backside illumination assembly, a frontside illumination device, a lens and detector assembly and at least one processor to process electrical signals generated by the lens and detector assembly.

摘要： A method and system for inspecting unidentified mixed parts to identify the parts are provided. The system includes an inspection station 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 so that a part axis of the part is substantially centered and aligned with a measurement axis of the inspection station during part rotation. A second subsystem optically measures a profile and features of the self-supporting part during part rotation. A processor is operable to compare the profile and the features of the part to be identified with the profile and corresponding features of stored templates to identify a template which matches the profile and features of the part to be identified and to generate and transmit an identification signal representing a part identification code for the part associated with a matched template.

摘要： 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.
