Abstract: Beijing Benz front-drive vehicle adopts a combination of gluing and hemming connection technology in the four doors and two covers to connect the inner and outer panels of the covering parts. The hemming glue of the covering part is not only used as a strength connection, but also plays an important role in corrosion prevention, so the main engine factory has a strict assessment of the hemming connection process. This article will introduce the hemming glue painting and hemming process of the cover parts of Beijing Benz front-drive vehicle, and analyze and introduce the solutions based on the problems encountered in the production process. After optimizing the hemming glue painting process and hemming process, the glue cleaning workload is reduced and the production downtime related to it is solved. At the same time, it improves the stability in the production process and improves product quality.
