Description

Technical Field

[0001] The utility model belongs to the technical field of automobile production equipment, and in particular relates to an automobile assembly workbench. Background Art

[0002] Cars are an indispensable means of transportation in modern society, and they greatly facilitate human work and life. In recent years, my country's automobile industry has developed rapidly, especially electric vehicle technology has been at the forefront of the world. In the automobile production process, the rear axle needs to be assembled, and its assembly parts are in order, and different operators are required to assemble them according to the assembly process sequence. In traditional assembly production, after the previous assembly work is completed, the rear axle and other parts of the car are sent to the next station by AGV trolleys and other carrying mobile devices. The transportation of the rear axle and other parts of the car in the above-mentioned way requires waiting for loading and unloading, which is time-consuming and labor-intensive, affecting the continuity of automobile assembly production and reducing production efficiency. Although some conveyor belt-type transmission devices can alleviate the problem of assembly process continuity to a certain extent, such equipment is often long, and the supporting parts for the assembly workpieces cannot be automatically circulated and need to be manually handled, which also has a certain impact on production.
