[0002] The vehicle chassis (also known as the chassis) refers to the skeleton structure that bears the weight of the vehicle and connects various components. It not only provides the basic framework of the entire vehicle but also supports important components such as the body, engine, suspension system, and transmission system. For the welding of the new energy vehicle chassis, a full-automatic welding device is usually adopted, which is combined with a welding robot arm and a motion track frame to achieve the full-automatic welding of the vehicle chassis.

[0003] In the existing full-automatic welding device for new energy vehicle chassis, before the welding operation is carried out, it is usually necessary to purge the vehicle chassis to be welded and the workbench to remove the influence of impurities on the welding surface. At the same time, after the welding is completed, it is also necessary to perform secondary purge cleaning on the welded vehicle chassis to avoid the accumulation of welding slag generated by welding on the vehicle chassis. However, due to the large area occupied by the vehicle chassis and the different heights of various structures on the top, there are various blocking surfaces, making it difficult to quickly achieve multi-directional cleaning operations for the current purge cleaning, and the actual cleaning effect is not good.
