Semi-automatic off-line coating production line for automobile parts

Abstract

The invention discloses a semi-automatic off-line coating production line for automobile parts. The semi-automatic off-line coating production line comprises a conveying line and a power source for controlling the conveying line to advance and stop; the conveying line sequentially comprises a charging zone, a dust removing zone, a primer leveling zone, a colored paint leveling zone, a varnish leveling zone, a baking zone, a cooling zone and a discharging zone; an off-line primer spraying zone which is not arranged on the conveying line is arranged between the dust removing zone and the primerleveling zone; an off-line colored paint spraying zone which is not arranged on the conveying line is arranged between the primer leveling zone and the colored paint leveling zone; and an off-line varnish spraying zone which is not arranged on the conveying line is arranged between the colored paint leveling zone and the varnish leveling zone. The coating production line has the characteristics ofhigh spraying efficiency and low manufacturing cost, and is automatic in spraying, good in employee operation environment, high in safety, complete in overall function and high in practicability.

Description

technical field [0001] The invention relates to the technical field of surface coating technology for auto parts, more specifically, it relates to a semi-automatic off-line coating production line for auto parts. Background technique [0002] In the existing surface coating process of auto parts, the material is usually loaded first, after dust removal, and then the primer, color paint and varnish are automatically sprayed one by one, and finally the parts are finished by baking and cooling. surface coating operations. [0003] In this process, the parts to be sprayed are placed one by one on the conveyor belt driven by the power source. Due to the requirements of the spraying area, the parts to be sprayed need to be covered with covers to cover the parts that do not need to be painted in this process, but Due to the large number of parts to be sprayed on the conveyor belt, there are also a large number of corresponding covers. The shapes of the covers are mostly non-standa...

AI Technical Summary

Problems solved by technology

[0003] In this process, the parts to be sprayed are placed one by one on the conveyor belt driven by the power source. Due to the requirements of the spraying area, the parts to be sprayed need to be covered with covers to cover the parts that do not need to be painted in this process, but Due to the large number of parts to be sprayed on the conveyor belt, there are also a large number of corresponding covers. The shapes of the covers are mostly non-standard parts with large differences, which require special custom processing, and the manufacturing cost is expensive, which affects the final coating. Product manufacturing cost

[0004] If it is changed to manual spraying by employees, the number of masks used will be reduced. Although the cost of processing masks will be reduced, the degree of automation will be reduced, and the production efficiency of painted products will also be greatly reduced. Moreover, the working environment of employees is poor and the safety is low. poor overall effect
