Patent number: 11543364Abstract: 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.Type: GrantFiled: May 16, 2019Date of Patent: January 3, 2023Assignee: General Inspection, LLCInventors: Michael G.

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.

Patent number: 11045842Abstract: 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.Type: GrantFiled: May 16, 2019Date of Patent: June 29, 2021Assignee: General Inspection, LLCInventors: Michael G.

Patent number: 10207297Abstract: Method and system for inspecting a manufactured part supported on an optically-transparent window of a rotary actuator at an inspection station are provided. The window rotatably supports the part in a generally vertical orientation at which a bottom end surface of the part has a position and orientation for optical inspection. An illuminator is configured to illuminate the bottom end surface of the part through the window with radiant energy to obtain reflected radiation signals which are reflected off the bottom end surface of the part. The reflected radiation signals travel through the window. A lens and detector assembly is configured to form a bottom image from the reflected radiation signals at a bottom imaging location below the window and is configured to detect the bottom image. The window is made of a material which is substantially transparent to the radiant energy and the reflected radiation signals.Type: GrantFiled: August 4, 2017Date of Patent: February 19, 2019Assignee: GII Inspection, LLCInventors: Michael G.

Patent number: 9370799Abstract: 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.Type: GrantFiled: October 6, 2015Date of Patent: June 21, 2016Assignee: GII ACQUISITION, LLCInventors: Michael G.
