Description

Technical field:

[0001] The invention belongs to the technical field of automobile production technology, and in particular relates to an automobile painting production technology. Background technique

[0002] Usually, in the painting process of automobile body, the mechanized process of the body has always been the main production artery of the paint shop, and the pre-treatment and electrophoresis conveying equipment need to withstand the continuous erosion of acid, alkali and organic solvent due to the poor working environment. Continuous operation for a long time in a high temperature and high humidity environment has high requirements for the selection of conveying equipment. The traditional process is a set of mechanized conveying procedures that are widely used in the automotive industry for pre-painting treatment and electrophoretic conveying equipment. It has many advantages such as plane conveying, vertical lifting, spreader swing, accumulation storage and so on. ...
