Description

Technical Field

[0001] The invention relates to the technical field of vehicle frame assembly, in particular to a vehicle frame assembly line with a detection function. Background Art

[0002] When some vehicles are produced in multiple processes, it is often necessary to set up an assembly line. For the assembly line of large vehicles, when the frame is transferred to the assembly line, a mechanized operation method is generally used. For the production of small vehicles, such as motorcycle and electric vehicle assembly lines, when the frame is transferred to the assembly line, it is generally placed in the assembly line by manual lifting.

[0003] At present, in the production process of locomotives (such as bicycles, motorcycles, electric vehicles, etc.), frame coding (i.e. marking numbers), pressing steel bowls, and filling steel bowls with butter are separate and independent processes. After the frame coding process is completed, the staff needs to move the frame to another hydraulic press to press the steel bowl. After completing the steel bowl pressing process, the frame is moved to the subsequent station to fill the steel bowl with butter. This production method has high labor intensity, low efficiency, high labor cost, and sometimes misses the butter in the bearing steel bowl. In addition, in the prior art, since the equipment is not equipped with a frame positioning device, the frame is not accurately positioned on the equipment, which is easy to damage the steel bowl, making the position of the frame number marking inconsistent.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a frame assembly line with a detection function is proposed. Summary of the invention
