【摘要】 为判断激光清洗效果，优化激光清洗工艺参数，对激光清洗效果进行评价就显出重要性。利用1 000 W级激光清洗机进行激光清洗实验，结合实验数据，运用机器视觉技术及表面性能测试技术从宏观和微观两个方面对激光清洗后的效果进行评价，提出清洁度、粗糙度、清洗效率3种评价指标；根据评价指标制定激光清洗效果等级评价体系“Lcq”,基于此体系开发激光清洗效果智能评估系统。测试结果表明：该激光清洗效果等级评价体系客观准确，系统运行稳定，可指导激光清洗设备现场作业，从而更快地调整激光清洗机参数，提高清洗效果。更多还原

【Abstract】 In order to judge the laser cleaning effect, optimize the laser cleaning process parameters, evaluating the laser cleaning effect is important.Laser cleaning experiment was carried out with 1 000 W laser cleaning machine.Combining experimental data, machine vision technology and surface performance testing technology were used to evaluate the effect of laser cleaning from both macro and micro aspects.Three evaluation indexes of cleanliness, roughness and cleaning efficiency were proposed.According to the evaluation index, the laser cleaning effect evaluation criterion “Lcq” was formulated.Based on this system, an intelligent evaluation system for laser cleaning effect was developed.The test results show that the laser cleaning effect rating evaluation system is objective and accurate, the system operation is stable, and the on-site operation of the laser cleaning equipment can be guided, so as to adjust the parameters of the laser cleaning machine faster and improve the cleaning effect.更多还原
