Abstract: The windshield of commercial vehicle cab is not only heavy, but also large in shape. Before the windshield of the company's conventional models is installed on the cab, it is necessary to carry out the sub-assembly of the embedded sealant strip. During this process, employees need to bend over and walk under heavy loads. The intensity is very high and seriously affects the occupational health of employees. This paper mainly expounds that the design team must solve the problem that the windshield sub-assembly operation is labor-intensive and affects the occupational health of employees. By analyzing the job site environment and employee workflow, using technical skills, we proposed design ideas, and finally decided on the design of auxiliary equipment. According to the plan, the team carried out grasping design, controlling design, flipping design and transferring design, as well as 3D testing, motion simulation and functional verification. Through the above methods, the auxiliary equipment was successfully put into the site and recognized by the operating employees. After the auxiliary equipment was put into use, the labor intensity of the windshield assembly operation was completely solved, and the occupational health of employees was guaranteed.
