Pretreatment optimization method for paint spraying

Abstract

The invention provides a pretreatment optimization method for paint spraying. The method is realized on the basis of integrated pretreatment combined equipment, and specifically comprises the following steps that (1) the front end of the inlet of the pretreatment combined equipment is hung on a hook function part of a suspension chain by a hanger, and then a part is hung on the hanger; and (2) thepretreatment combined equipment is started, a pretreatment combination chain is started, then under drive from the suspension conveying chain of the integrated pretreatment combined equipment, the part sequentially passes through a front spraying type water washing unit, a first dripping section, a spraying type pickling unit, a second dripping section, a rear first spraying type washing unit, athird dripping section, a rear second spraying type water washing unit, a fourth dripping section, a rear third spraying type water washing unit, a fourth dripping section and a compressed air automatic drying unit, and the pretreatment process is completed. The method is realized on the basis of the pretreatment combined equipment, manual wiping is replaced by the arrangement of the dripping sections, so that the pretreatment efficiency is improved, and through three-time water washing after pickling, surface cleanliness of the part is guaranteed.

Description

technical field [0001] The invention belongs to the field of pretreatment of parts for painting, and relates to a pretreatment optimization method for paint spraying. Background technique [0002] At present, before non-metallic parts are painted, they usually go through the process of pre-washing-pickling-post-washing, specifically: pre-washing equipment, after washing, stand still in the equipment for a period of time, let the parts drop the water on the surface, and manually wipe The surface of the parts; then, carry out pickling, stand still in the equipment for a period of time, let the parts drop the pickling solution on the surface, and manually wipe the acid solution on the surface of the parts; finally, wash the equipment with water, and then manually wipe the surface of the parts after washing. [0003] Since pre-washing, pickling, and post-washing all use separate equipment, manual wiping transition is required between them, resulting in high labor intensity and l...

Problems solved by technology

[0003] Since pre-washing, pickling, and post-washing all use separate equipment, manual wiping transition is required between them, resulting in high labor intensity and low work efficiency, and manual wiping is not easy to clean the surface of parts, and the surface of parts is not clean, which affects the quality of painting of parts
