[0002] Existing rivet quality inspection technology mainly relies on manual inspection or simple single-point inspection equipment, which has problems such as low inspection efficiency, lack of pertinence, and inability to meet mass production needs. Manual inspection is prone to problems such as fatigue and subjectivity, which makes it difficult to ensure the accuracy and consistency of the inspection results. Traditional single-point inspection equipment can only perform one or several inspections on rivets and cannot comprehensively evaluate the various quality indicators of rivets. With the expansion of the scale of rivet production, the demand for rivet quality inspection is increasing, and there is an urgent need to find more efficient and comprehensive inspection solutions.

[0003] Existing rivet quality inspection equipment mainly focuses on shearing inspection, internal damage inspection and pulling inspection.
