[0002] Rearview mirrors reflect the situation behind, to the sides, and below the car, allowing drivers to indirectly see these areas. They act as a "second eye," expanding the driver's field of vision. With the increasing trend of lightweighting in automobiles, carbon fiber materials are widely used in rearview mirror manufacturing due to their advantages of high strength and low weight. The assembly precision of carbon fiber rearview mirrors directly affects the safety performance of automobiles.

[0003] The inspection of carbon fiber rearview mirrors mainly includes the inspection of the external outline dimensions, the position of the connectors, the mirror mounting gap, and the mounting gap between the rearview mirror and the vehicle body. Among these, the connectors are located on the inner surface of the carbon fiber rearview mirror, and the mounting parts that can be used for clamping are also located on the inner surface of the carbon fiber rearview mirror. Under this structure, how to simultaneously meet the requirements of clamping and multiple inspections in one go is a key research direction in the industry, in order to avoid positioning errors caused by multiple clamping.
