At present, most of ring joint toothed chain manufacturers rely on operators to check whether the chain is in short parts or not by naked eyes, and whether the assembled part has defects (such as deformation of an outer sheet, non-riveting of a rivet, left and right eccentricity after riveting and the like), so that the detection method has low automation degree, low detection efficiency, high labor intensity and high labor cost, has the problems of missing detection, wrong detection and the like, and cannot meet the current requirement of mass production. At present, part of chain detection devices are arranged on the market to replace part of manual work, but the detection efficiency is lower, only one chain can be detected, the waiting time of an intermediate action link is long, the detection is carried out after the manual tensioning is needed after the feeding, and the detection precision is not high.
