The invention relates to the field of laser cleaning, in particular to a laser cleaning method for the outer surface of an automobile lampshade. Comprising the following steps: S1, traversing and scanning an automobile lampshade image, and determining an automobile lampshade pollutant area; s2, performing traversal scanning on the pollutant area of the automobile lampshade to obtain a 3D morphology image of pollutants; s3, comparing to obtain an accurate pollutant area; s4, distance signals between all coordinate points of the accurate pollutant area and the pulse laser are measured, the focal length of the pulse laser is adjusted based on the distance signals so that the pulse laser can be gathered on the surface of the automobile lampshade, optimal laser cleaning parameters are determined according to pollutant parameters, and laser cleaning is conducted; s5, the automobile lampshade is blown or sucked; and S6, automobile lampshade pollutant parameters are obtained and compared with all parameters before current cleaning, whether the requirements are met or not is judged, and if not, the step S4 is executed again. In the cleaning process, proper laser cleaning parameters can be automatically selected, automatic focusing is achieved, and the cleaning effect and efficiency are improved.

    本发明涉及激光清洗领域,具体涉及一种汽车灯罩外表面激光清洗方法。包括:步骤S1,遍历扫描汽车灯罩图像,确定汽车灯罩污染物区域;步骤S2,对汽车灯罩污染物区域进行遍历扫描,获得污染物的3D形貌图像;步骤S3,对比得到精确污染物区域;步骤S4,测量精确污染物区域各个坐标点与脉冲激光器之间的距离信号,基于距离信号调整脉冲激光器的焦距使其聚集于汽车灯罩表面,根据污染物参数确定最优激光清洗参数,进行激光清洗;步骤S5,吹扫或吸扫汽车灯罩;步骤S6,获取汽车灯罩污染物参数,与当次清洗前的各参数对比,判断是否满足要求,如果不满足,返回步骤S4。本发明可在清洗过程中自动选取合适的激光清洗参数及自动对焦,提高清洗效果及效率。
