Multi-color pattern and character chromatic spraying technology for automobiles

Abstract

The invention discloses a multi-color pattern and character chromatic spraying technology for automobiles. The multi-color pattern and character chromatic spraying technology comprises the following steps: S10, making a hollowed spraying shielding formwork; S20, gluing the hollowed spraying shielding formwork to the surface of a workpiece; S30, separating transferring layers from formwork layers along the cutting lines of the transferring layers, and folding the transferring layers along folding lines until the transferring layers are perpendicular to the formwork layers; S40, removing the transferring layers in a chromatic region; S50, spraying a paint with a corresponding color in each spraying region; S60, drying the sprayed workpiece at low temperature; S70, removing the formwork layers and the transferring layers on the surface of the workpiece; and S80, examining chromatic paint films and trimming flaw parts. Through the steps, the regions with different colors can be separated, and different separated regions are separately sprayed, so that the spraying of multiple colors is carried out through one shielding. Then, through one drying, multi-color pattern and character color chromatography is realized. Multiple problems in the prior art are solved.

Description

technical field [0001] The invention relates to an automobile color registration coating process, in particular to an automobile multicolor graphics and text color registration coating process. Background technique [0002] Chromatic coating process is a relatively common process method for automobile painting, which can spray two or more colors of paint on the same plane to achieve decorative and beautifying effects. The chromatic spraying process requires accurate position, clear and straight boundaries, and no defects such as sawtooth, cracking, and paint accumulation. Multi-color graphic and text registration is one of the most difficult color registration coating processes due to the variety of colors and irregular interface shapes. [0003] At present, the existing multi-color picture-text color registering coating process is no different from the ordinary color registering coating process. They all complete a color after sequentially implementing the processes of dra...

AI Technical Summary

Problems solved by technology

However, multi-color graphic and text color registration has the characteristics of many colors and irregular interface shapes. It is difficult to draw lines and mask, and it is easy to cause defects such as interface blur and displacement. At the same time, the existing process can only spray one color at a time. Multi-color graphic and text registration requires multiple masking, multiple spraying, and multiple dryings, which is inefficient and causes unnecessary waste of materials and energy
