Car body electrophoretic coating production line

Abstract

The invention relates to the field of car body coating, in particular to a car body electrophoretic coating production line. The car body electrophoretic coating production line comprises part loadingtransferring equipment, and an outlet of the part loading transferring equipment is connected with an inlet lifter through a conveying chain. The outlet end of the inlet lifter is connected to an electrophoretic coating channel through the conveying chain, and a coating device, a spraying device and an immersion cleaning device are sequentially arranged in the electrophoretic coating channel fromthe inlet end to the outlet end. The outlet end of the electrophoretic coating channel is connected with an outlet lifter through the conveying chain, and an outlet of the outlet lifter is connectedwith part discharging transferring equipment through the conveying chain. The car body electrophoretic coating production line is high in operation stability, high in automation degree and good in coating effect.

Description

technical field [0001] The invention relates to the field of automobile body coating, in particular to an automobile body electrophoretic coating production line. Background technique [0002] Automobile painting is a pyramid in the field of painting. The level of automobile painting represents the highest level of a country's painting. The automobile painting production line is an automated industrial production line for large-scale continuous production. The requirements for the quality of the coating are very high. The mechanized conveying system of the car body is the main artery of the painting production line. The pre-treatment electrophoresis conveying system is an important part of the conveying system of the painting production line. Due to the poor working environment, it needs to withstand acid, alkali and organic solvents. Continuous erosion, continuous and stable operation in a humid, pH environment, has high requirements for conveying equipment. The current pre...

AI Technical Summary

Problems solved by technology

[0003] At present, the accumulative suspension chain conveyor and pendulum chain conveyor equipment mainly have deep cavity air bubbles on the roof or front and rear covers that cannot be electrophoresis coated, the thickness of the electrophoretic film on the roof is relatively thin, electrophoretic particle defects are prone to occur on the roof, and the angle of entry and exit slots 30° or 45°, the equipment occupies a large area, the invalid volume of the tank body is large, resulting in high equipment operating costs, insufficient drainage, resulting in more water, resulting in high chemical and water consumption, and the coating process is not flexible. The chain has the risk of polluting the tank solution; EMS self-propelled hoist conveying equipment has deep cavity bubbles on the roof or front and rear covers that cannot be electrophoretic coated, the thickness of the electrophoretic film on the roof is too thin, electrophoretic particles are prone to defects on the roof, and the drainage is not good. It fully causes problems such as high water consumption, high chemical and water consumption, and limited production capacity (currently only applicable to production lines with a production cycle of less than 3 minutes). Arbitrary adjustments according to needs, no selectivity and flexibility in the process (it can only be operated according to a fixed process route), and the movement part is immersed in the liquid surface with high waterproof requirements, etc.
