提出了一种汽车漆面缺陷自动打磨抛光的工艺研究及测试方法,介绍了一种应用到汽车涂装修饰线上的基于工业机器人的打磨抛光自动化系统,通过机器人程序控制前端打磨装备的工艺参数来实现自动磨抛对于漆面缺陷的修复。工艺试验分为前期板材试验和实际产线上连续测试两个步骤,通过控制打磨抛光的正压力、砂纸/抛光垫转速和行进速度等工艺参数,测试漆面材料粗糙度和膜厚等指标来评估工艺质量。研究结果表明此方法可以实现汽车漆面缺陷机器人自动磨抛的工艺参数配方的制定。

A method is proposed to research and test the process parameters for automatic car paint sanding and polishing process.A robot system for automatic sanding and polishing system is introduced to the finishing line of car paint workshop,in which the process control is realized through the control of sanding/polishing tool system by robot programs.The test procedure is divided into two phases:material test in lab and continuous test on production line.The parameters including pressure force on surface,rotation speed of the tool and feedrate of the robot are controlled in the tests and the quality results are evaluated by the finished surface roughness and paint layer thickness.The test results demonstrate that this method can realize the construction of process database for car paint defect automatic repair process.
