Abstract: Aiming at the production demand of diversified automobile products and flexible models, there are many kinds of error proofing in workshop site. This paper introduces the error proofing methods such as mechanical limit error proofing device, equipment detection reminder and intelli- gent error scanning through examples, which reduce the quality defects of similar parts in proofing site such as misassembly, missing assembly, missing welding and position deviation, and improve the output efficiency of body in white. At the same time, the error proofing of the production line is summarized to provide reference for other enterprises.
