Embedded flexible assembly system for Car Latch based on laser identification

Car Latch (CL) has very complex mechanical structure, requiring strict technological process, and it is difficult to realize automatic manufacturing. In allusion to above problem, a kind of embedded flexible assembly system (FAS) for CL based on laser identification (LAI) has been put forward according to wide investigation and analysis for current CL assembly technology. In this paper, FAS idea is firstly brought into CL manufacturing. So kinds of CL can be assembled according to different production demands and flexibility of this system can be fully presented. CL structure and its technological processes are analyzed. By the introduction of LAI, Latch piece location and key outline identification problems are resolved in process of its assembly. Embedded micro process unit (EMPU) acts as a main controller, and closed loop control system, which has abundant control functions is implemented to realize control task for the whole assembly process. The idea of modularization is adopted, and that makes this system have strong augmentability and multiplexing ability to meet different assembly demands. A number of industry field experiments proved that this system locates exactly, runs stably, and increases the production efficiency of CL.
