[0002] The quality of the electric vehicle frame, the skeleton of the entire electric vehicle, is directly related to the personal safety of the user. Therefore, the design and manufacturing of the frame has become the most important production and processing link for electric vehicle manufacturers.

[0003] After the frame is cast, in order to improve its corrosion resistance, some corrosion-resistant paint is usually sprayed on the frame. In the actual production process, after the spraying robot sprays the frame, some unsprayed areas will be left on the frame, which requires rework, which is time-consuming.

[0004] In the existing technology, the spray filling mechanism for electric vehicle frames has poor portability, and when spraying and filling the electric vehicle frames, the paint produced by the spraying is easily dispersed in the air, which is inconvenient to recover. The dispersed paint not only causes great harm to the workers' health, but also causes great waste. Therefore, we have introduced a spray filling mechanism for electric vehicle frames.
