Error-proof design and application of pre-assembly process
The pre-assembly process of automobile wiring harness manufacturing includes two operation modes: concentrated area pre-assembly according to order batches and product models, and assembly line online pre-assembly. If necessary, there will be mixed applications of the two pre-assembly modes. Since there is basically no automated equipment operation in the pre-assembly process, it is a labor-intensive operation process. Therefore, the application of this process through process error-proof design and tooling error-proof design is the most common. At the same time, the quality of process error-proof design directly affects the assembly line. the final assembly efficiency and the quality of the finished wire harness. In the design process of the pre-installation process card, in addition to considering the time beat and operability of the pre-installation operation, it is more important to consider the process error-proof design of the pre-installation operation. If the sheath is symmetrical and the self-locking feature is not obvious, the threading space or special requirement information must be marked on the pre-assembly process card. If necessary, the photo of the sheath should be attached to the pre-assembly process card to avoid batch threading wrong holes. bit.
