摘要:: 显示板作为高铁系统中信号指示零件，其材料为不锈钢，加工方式主要以喷漆工艺为主，在其表面需要喷涂黄绿色、红橙色和深黑色3种不同颜色面漆且同时满足各部位尺寸、厚度(60～200 mm)及结合力要求。在喷漆过程中零件出现分界线模糊、尺寸超差、外表面有颗粒物和橘皮等质量问题。本文以显示板喷漆工艺质量缺陷改进为目标，通过改进喷漆前处理工艺、优化喷漆工艺流程、工艺参数及设计喷漆工装，使得喷漆表面得到大力改善，并满足距边缘1 mm处不喷漆要求，达到客户验收标准。

Abstract:: Absrtact: As a key indicator part in the high-speed rail system, the display board was made of stainless steel and mainly processed by spray painting. The surface of the display board needed to be sprayed with three different colors of topcoats, yellow-green, red-orange and dark-black, while meeting the requirements of size, thickness ranging from 60 to 200 mm and binding force of each part. However, during the painting process, the parts may have quality issues such as blurred boundary lines, oversized dimensions, particles on the outer surface, and orange peel. In this paper, the improvement of painting process quality defects of display board was taken as the research object. By improving the pre-treatment process of spray painting, optimizing the spray painting process flow, process parameters, and designing spray painting fixtures, the spray painting surface has been greatly improved, meeting the requirement of no spray painting at a distance of 1 mm from the edge and meeting customer acceptance standards
