Abstract: Combines the electrophoretic liquid accumulation defect in the hinge hole of a certain car's front cover that occurred during the actual production and manufacturing process. In the process of solving this problem, the author transformed the actual on-site problem into a mathematical model, and used Python language programming and computer-aided solution to quickly obtain the theoretical probability of the problem occurring. The introduction of this article is a typical case of using digital thinking to solve engineering problems. It has certain reference significance for engineering personnel to analyze and solve problems, and has good reference value for promoting the use of digital thinking by all members of the manufacturing industry.
