Description

Technical Field

[0002] At present, with the rapid development of the automobile industry, car interiors are receiving more and more attention. A high-quality automobile product must not only ensure the customer's driving safety and power, but also make the customer feel visually comfortable in terms of appearance.

[0003] In the existing assembly line of the cockpit module of the automobile, a fixed structure hanger is used. During the assembly process, due to the wide variety of parts to be assembled, the cockpit module needs to be turned over several times to complete. When assembling with the traditional fixed structure hanger, the assembler can only perform the assembly work by turning his body.
