Electrophoresis treatment system of automobile body

Abstract

The invention provides an electrophoresis treatment system of an automobile body. The electrophoresis treatment system comprises a first exhaust channel extending into a closed automobile body part through a vent hole in a closed automobile body part, wherein a hollow buoyancy ball is arranged at one end of the first exhaust channel, and an air storage bag is connected with the other end of the first exhaust channel. According to the scheme, air remained in a dead angle in the closed automobile body part is discharged into the air storage bag by adopting the first exhaust channel, an electrophoresis solution is fully immersed in the closed automobile body part so that the electrophoresis treatment effect is ensured. Meanwhile, the hollow buoyancy playing a role of a life ring can drive the first exhaust channel to continuously move in the closed automobile body part so that the air remained in the narrow dead angle is maximally discharged. Meanwhile, an inner exhaust channel can be melted during subsequent treatment without influencing the subsequent procedure.

Description

technical field [0001] The invention relates to the technical field of electrophoresis treatment of airtight components, in particular to an electrophoresis treatment system for a vehicle body. Background technique [0002] In recent years, with the development of the economy and the progress of the society, automobiles have become more and more popular. At the same time, the competition among various automobile manufacturers has become more and more fierce. High quality and low price are the goals that OEMs are constantly pursuing. Since the existing vehicles use a large number of metal parts, the antirust performance of the vehicle directly affects the service life of the vehicle, and the existing vehicles all need electrophoresis treatment on the body to improve the corrosion resistance. [0003] When the existing car body is subjected to electrophoresis treatment, the car body is immersed in the electrophoretic liquid, but because part of the car body is airtight, the ai...

AI Technical Summary

Problems solved by technology

When performing electrophoresis treatment, it is necessary to figure 1 As shown, the A-pillar cavity is immersed in the electrophoretic fluid 6, but due to the airtight space between the side wall outer panel 1 and the A-pillar reinforcement panel 3, the air 2 cannot be completely discharged, so that the electrophoretic fluid 6 cannot contact the inner wall of the A-pillar cavity. All positions are in contact, and the effect of electrophoresis treatment is not good

And the same problem also exists in the B-pillar cavity, door window frame, C-pillar, door sill, longitudinal beam and other body airtight parts
