Patent ID: 8213702

Claim:
An automated testing device for fasteners, comprising: a platform; a rotational plate on a top side of said platform; and an uploading member, a guiding member, an optical testing member, and an unloading member, sequentially positioned around said rotational plate along a rotational direction of said rotational plate; wherein said rotational plate is a circular plate made of a metallic material or transparent glass; said uploading member comprises a rail where fasteners to be tested are placed and delivered sequentially in an upright manner to said top side of said rotational plate; said guiding member comprises a shut element having a curved surface above said rotational plate to align said fasteners to be tested along a specific path; said optical testing member comprises at least an image capturing element for obtaining and examining at least a profile image for each fastener to be tested on said path; an unloading member comprises a first unloader and a second unloader positioned sequentially along said rotational direction of said rotational plate which drive substandard and qualified fasteners out of said rotational plate, respectively; said uploading member further comprises an overturning element between an output end of said rail and said top side of said rotational plate; said overturning element comprises a wheel set and a matched horseshoe-like piece; said wheel set comprises an inner wheel and an outer wheel in parallel so that a body section of each fastener to be tested is held between said inner and outer wheel; and a curved passageway between said piece and said wheel set is provided so that a cap section of each fastener to be tested moves along said passageway.
