The assembly inspection line includes the assembly process of all rearview mirror parts, such as substrate sub-mirror housing, steering lamp, steering motor, pin shaft, bracket, lens, mirror ring and lens, etc. The product circulation is made between stations through segmented double-speed chain, and all machines in the production line can be withdrawn from the line body and switched to stand-alone state for use. The whole line can meet the production requirements by increasing or decreasing the number of machines, which greatly improves the flexibility of the line body; It can not only adjust the equipment sequence due to the change of process flow, but also leave room for upgrading and optimization for the subsequent line upgrading requirements caused by product compatibility problems. The assembly inspection line has the function of tracing the whole two-dimensional code data; The picture on the right shows a variety of different types of rearview mirror intelligent assembly inspection lines developed according to different customer needs.
