Abstract: Based on the problem of bump and scratch in the trial production of a sample vehicle, this paper conducts a process verification analysis on how to reduce the causes of bump and scratch in the assembly process from the aspects of field process, process equipment, supplier management, logistics transfer in the production workshop. By optimizing the production site environment, promoting standardized operations, updating the production line tooling equipment, and improving the training of operators, it can effectively prevent the occurrence of vehicle bumps and scratches, ensure product quality, reduce rework and repair costs, improve production efficiency, and provide improvement direction for the later vehicle assembly and transport process to achieve the goal of no bumps and scratches.
