摘要
为实现锂电池极柱表面高效清洗,本文开展了MOPA脉冲光纤激光器协同高速振镜(焦距F=254 mm)的激光清洗试验研究。系统探究了激光功率、划线速度、跳转速度及作用时间等参数对锂电池极柱清洗效果的影响,通过观测清洗后极柱的外观色泽、清洁度、清洗效率、表面粗糙度及显微划痕等指标,分析工艺参数与清洗质量的相关性。研究表明,当清洗深度超过10μm时,受功率、划线速度等参数波动影响,极柱外观与清洗深度一致性较差,且存在表面材料损伤风险;而在(3~6)μm清洗深度区间内,极柱表面清洁度高、无明显缺陷,清洗时间可控制在0.82 s以内,能有效去除轻微划痕及表面异物。本研究成果为锂电池极柱及同类产品的激光清洗工艺优化提供了重要参考依据。
To achieve efficient cleaning of lithium battery pole surfaces,this paper conducts a laser cleaning experiment using a MOPA pulsed fiber laser in conjunction with a high-speed galvanometer(focal length F=254 mm).The effects of parameters such as laser power,marking speed,jump speed,and action time on the cleaning effect of lithium battery poles are systematically investigated.By observing indicators including the appearance color,cleanliness,cleaning efficiency,surface roughness,and microscopic scratches of the poles after cleaning,the correlation between process parameters and cleaning quality is analyzed.The research conclusions show that when the cleaning depth exceeds 10μm,affected by fluctuations in parameters such as power and marking speed,the consistency of the pole appearance and cleaning depth is poor,and there is a risk of surface material damage.When the cleaning depth is within the range of(3~6)μm,the pole surface has high cleanliness,no obvious defects,the cleaning time can be controlled within 0.82 s,and it can effectively remove slight scratches and surface foreign matters.The research results provide an important reference for the optimization of laser cleaning processes for lithium battery poles and similar products.
