An all-round electrophoretic coating device for the production of automobile shells

Abstract

The invention discloses an all-around electrophoretic coating device used for automobile housing production. The all-around electrophoretic coating device comprises a coating workbench, wherein a variable-frequency regulating device, a polar liquid supply device, a coating slot filled with coating paint, a closed loop cleaning device used for cleaning the surface of a coated workpiece, a combineddrying device for the surface of the cleaned workpiece, and a coating clamp body for clamping the workpiece to complete electrophoretic coating are arranged above the coating workbench; a coating solution stirring device and a plurality of anode polar cases of tubular structures are arranged in the coating slot; one end of the closed loop cleaning device is connected with the coating slot; the variable-frequency regulating device is separately connected with one end of the coating solution stirring device, one end of the closed loop cleaning device, one end of the polar liquid supply device and one end of the combined drying device; and two automobile body sensors are arranged in each of the closed loop cleaning device and the combined drying device. The all-around electrophoretic coatingdevice is simple in structure, is simple and convenient to operate, and can realize the efficient, reliable and all-around electrophoretic coating function for the surface of an automobile housing.

Description

technical field [0001] The invention relates to the technical field of automobile shell production, in particular to an all-round electrophoretic coating device used for the production of automobile shells. Background technique [0002] As an important part of the overall structure of the car, the car shell affects the appearance of the car and the performance of the car. The car shell needs to be painted during production. The paint can protect the car from corrosion, enhance the scratch resistance of the car and Pollution resistance of the surface of the car. In addition, various coating colors can also make the car have a certain aesthetic. The existing coating process of the car shell is: pre-paint treatment (degreasing and phosphating)→electrophoretic coating Install primer → apply weld sealant and anti-stone chip coating → apply intermediate coating, inner surface coating with the same color as topcoat and anti-cracking layer → apply topcoat → apply anti-rust wax insid...

AI Technical Summary

Problems solved by technology

[0010] (1) High-power equipment such as paint circulation pumps, cleaning pumps, and polar liquid pumps are used in electrophoresis production. The various pumps used in these equipments usually operate continuously under power frequency conditions, consuming a lot of electricity, making the coating of automobile shells Increased costs;

[0011] (2) After electrophoretic coating on the surface of the car shell, the surface is cleaned with pure water, and the waste water generated by the cleaning is discharged directly, which will not only pollute the environment, but also because some paint will remain on the surface of the car shell, it will directly follow the waste water discharge, it will also cause waste of paint;

[0012] (3) During electrophoretic coating, hooks are often used to directly immerse the car shell into the coating tank filled with paint. In the subsequent process of position transfer of the car shell, it is also done through the hook. This method has The car shell is easy to fall off from the hook, the electrophoretic coating is uneven, etc., so that the quality of the electrophoretic coating on the surface of the car shell cannot be guaranteed
