Automobile body color register coating process

Abstract

The invention discloses an automobile body color register coating process. By means of the process steps of drawing confirming, automobile body cleaning, point plotting, location, contour line adhesion, polishing, roughening, cleaning, dust removing, shielding, protection, spray coating, shield removing, miscellaneous paint removing, drying and maintaining which are conducted successively, total planning is conducted to coating work by means of drawings before coating work, locating, wire drawing and other process construction processes are accurate and reliable, and the polishing and roughening processes are conducted before an non-color-register area is shielded. Particles produced in a polishing process are effectively prevented from being adsorbed to the shielded part of the non-color-register area, and a total coating effect and coating quality of the automobile body color register coating process are effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicle body spraying, in particular to a color coating process for a vehicle body. Background technique [0002] The over-color coating process is a relatively common vehicle appearance modification process, which can re-coat one or more layers of different coatings on the surface of the existing paint film to change the appearance of the vehicle, thereby providing the daily use of the vehicle. better decorative effect. [0003] During the implementation of the current motor vehicle over-color coating process, although the basic vehicle painting needs can be met after the sequential implementation of punctuation and drawing, masking of non-over-color areas, grinding, spraying, cleaning of paint mist, and baking and shaping, etc., However, since the punctuation and wire drawing process is implemented by human judgment and operation, the positioning accuracy and the controllability of the wiring are poor,...

AI Technical Summary

Problems solved by technology

[0003] At present, in the implementation process of the existing motor vehicle color registration coating process, although the basic vehicle coating needs can be met after the sequential implementation of the punctuation drawing, covering the non-color registration area, grinding, spraying, clearing the paint mist and baking and setting, etc., However, because the punctuation drawing process is carried out by human judgment and operation, the positioning accuracy and controllability of the alignment are poor, which can easily lead to poor spraying quality and spraying effect of the final product, and even require rework in serious cases; at the same time, due to The existing process is to cover the non-colored area first and then polish and remove the dust in the colored area. The particles generated during the grinding process are easily adsorbed to the shade of the non-colored area, which will have an adverse effect on the final product spraying quality.
