Abstract: The wrong-hole problem of automation assembly is one of the fault problems that often occur during the production process of automobiles, and the causes of it are complicated and diverse. This article takes the automatic assembly of the subframe wrong-hole faults in the industrialized trial stage of S-new model in a certain company as an example. The troubleshooting process in the actual production process is summarized. It mainly detailed analyzes the reasons for the wrong-hole when the subframe is automatically assembled from the aspect of the coating process and the white body structure, and by means of benchmarking analysis method, effective improvement measures for structural optimization are put forward to solve the problem of wrong-hole problem of automatically assembled, so as to solve the practical problem. It is hoped that through this case sharing, it can provide practical experience and useful ideas for automated technical personnel in the automotive industry, and reduce the incidence of automatic assembly wrong-hole.

Key words: subframe; assembly wrong-hole; the size of the Y-direction opening; process ability verification; open structure; closed structure
