Description

Electrophoresis-free flowing tool for automobile coating process

Technical Field

The utility model belongs to the technical field of car application equipment, concretely relates to car application process is with preventing electrophoresis trickling frock.

Background

In the process of automobile production, electrophoresis on an automobile body is an important part for ensuring surface quality, in the electrophoresis process, electrophoresis flow (also called electrophoresis flow mark) is a common defect, the electrophoresis flow refers to that electrophoresis liquid with a certain solid content is remained at the pressing edge and other parts of an electrophoresis paint film in the process of heating and curing, the electrophoresis liquid flows out from gaps of the pressing edge and other parts and drips on other appearance areas to damage the appearance of the paint film, particularly for white automobile models, the defect is more obvious and is usually also called electrophoresis flow defect, the electrophoresis defect is most frequently generated at the position of a rear cover because the rear cover is opened during heating and curing, the rear cover in an opened state, the left side and the right side of the rear cover are pressed, and the sharp corners of drain holes of the rear cover face downwards, and the remained electrophoresis liquid drips on the surface below along the sharp corners at the two sides of the rear cover at the moment, so as to generate the electrophoresis flow defect, after the electrophoresis flow defect occurs, the flow mark can be removed only by polishing, the polishing of the flow mark can cause the defects of increase of abrasive materials, generation of particles on the surface of paint and the like, and more seriously, the polishing can cause damage of an electrophoresis paint film, a phosphorization layer and even a zinc coating layer, so that the corrosion resistance is reduced, and therefore, the most practical and efficient treatment method is to solve the electrophoresis flow or the electrophoresis flow mark in the production process.

A document entitled "reason and treatment for electrophoretic flow mark generation of a pressed edge" is published in the book No. 1 of volume No. 22 of 2019, which is a journal in China, and the document records a main measure for reducing electrophoretic flow marks in the prior art, namely, edge folding glue is arranged in an edge folding area, an edge folding part is filled with the edge folding glue, or a pressing gap is reduced, so that electrophoretic liquid is prevented from remaining in the edge folding part, or a blowing room is arranged after electrophoresis to blow by compressed air, and certainly, adjustment can be carried out from the aspect of an electrophoresis process, and according to the experimental result of the document, the methods can effectively reduce the generation of electrophoretic flow marks; however, these methods require additional steps to be added to the original process flow for filling or purging with compressed air, which increases the cost and reduces the production efficiency, and meanwhile, if the purging chamber is used, the compressed air in the purging chamber has higher noise and higher humidity, which is not beneficial to the health of workers.
