摘　　要：针对纯铝设备线夹表面氧化层的清理需求,研究纳秒脉冲激光清洗纯铝设备线夹表面氧化层的工艺。通过不同工艺参数下的对比试验,研究不同功率和光斑叠加率对激光清洗效果和清洗效率的影响。在高效率激光清洗的前提下,通过研究不同重复频率和扫描次数对激光清洗效果的影响,进一步优化纯铝设备线夹表面氧化层激光清洗工艺。结果表明:在高功率、50%的光斑叠加率工艺设定下,氧化污染表面具有良好及高效的清洗效果;在上述基础工艺上,优化重复频率和扫描次数,能进一步提升表面的清洗效果;过高的功率、光斑叠加率及扫描次数,均会造成表面的过清洗。In order to clean the oxide layer on the surface of the wire clamp of pure aluminum equipment, the technology of nanosecond pulsed laser cleaning the oxide layer on the surface of the wire clip of pure aluminum was studied. The influence of different power and spot overlap rate on cleaning effect and efficiency was studied by comparing experiments under different process parameters. Under the premise of high-efficiency laser cleaning, the laser cleaning process of oxide layer on the surface of wire clamp of pure aluminum was optimized by studying the influence of different repetition frequency and scanning times on the laser cleaning. Results show that: with the process setting of high power and 50% spot overlap rate, it has better and efficient cleaning effect. In the pre-foundation process, the surface would have more obvious cleaning effect if it is cleaned with the appropriate repetition frequency and scanning times. When the power is too high, spot overlap rate and scanning times will cause over surface cleaning.
