摘　　要：针对返厂铝合金模板的清洗,目前行业内采用的主要清洗方式为抛丸清洗和水清洗,但受抛丸清洗和水清洗的技术特性的限制,二者在清洗效果方面均有一定的缺陷。提出一种新思路,即采用激光清洗技术完成返厂铝合金模板的清洗,激光脉冲辐射铝合金模板表面,混凝土残渣和喷涂层颗粒产生高频振动,使其与铝合金分离以达到清洗的效果。应用该方式,可以实现在不影响铝合金模板力学性能和外观质量的情况下,达到完全去污的目的。同时以激光清洗技术为核心,设计一套自动化清洗设备,使清洗过程更加智能、高效。For the cleaning of returned aluminum alloy templates,the main cleaning methods used in the industry are shot blasting and water cleaning,but due to the technical characteristics of shot blasting and water cleaning,both have certain defects in terms of cleaning effect.This paper proposes a new idea,that is,to use laser cleaning technology to clean back-work aluminum alloy templates,laser pulse radiation aluminum alloy template surfaces,high-frequency vibration of concrete residues and spray coating particles,so that they can separate them from aluminum alloy to achieve cleaning effect.Using this method,it can achieve the goal of complete decontamination without affecting the mechanical performance and appearance quality of aluminum alloy templates.At the same time,with laser cleaning technology as the core,an automatic cleaning equipment is designed to make the cleaning process more intelligent and efficient.
