The auxiliary device comprises an electrophoresis tank, a copper bar, an electric brush, a cable with an insulation layer, a connecting base, a high-temperature cable, an auxiliary anode plate, a vehicle body lifting appliance and the vehicle body; the copper bar is fixed to the side face of the electrophoresis tank and is in insulation connection with the electrophoresis tank, the copper bar is connected with the electric brush, the electric brush, the cable with the insulation layer and the connecting base which are sequentially connected are fixedly mounted on the vehicle body lifting appliance and run along with the vehicle body lifting appliance, and the high-temperature cable is fixedly connected with the auxiliary anode plate and is connected with the connecting base through a connecting part; the auxiliary anode plate is suspended in the vehicle body; according to the device, the electrophoresis quality of the vehicle body can be greatly improved, and the thickness of a paint film is more uniform.

Description

technical field [0001] The invention relates to an auxiliary device, in particular to an auxiliary device inside a vehicle body. Background technique [0002] In the electrophoresis process of the automobile automatic coating production line, cathodic electrophoresis is generally used, that is, the body is connected to the cathode of the electrode, which is negatively charged; the electrophoretic paint is a cathodic ion, which is positively charged. When energized, electrophoresis occurs due to the interaction of positive and negative electrons, and a uniform paint film is formed on the surface of the vehicle body. Now the automobile manufacturing industry commonly uses the electrophoresis method in which the body is directly connected to the electrode. When the body is a large body, especially a closed body, because the internal electric field is shielded, a large number of negative electrons are distributed on the outer wall of the body, and the electrons on the inner wall...
