Laser cleaning technology refers to the use of high energy laser beam to irradiate the surface of the workpiece, so that the surface of the dirt, rust or coating instantaneous evaporation or stripping, so as to achieve a clean process. The laser cleaning mechanism is mainly based on the absorption of laser energy by surface pollutants, or vaporization and volatilization, or instant thermal expansion to overcome the adsorption force of particles on the surface, so that laser cleaning can adapt to the cleaning of various surface dirt, minimal environmental pollution, and can do no damage to the matrix. At present, the method has become a supplement and extension of the traditional cleaning method, and has shown broad application prospects because of its inherent advantages. It has the following characteristics:
(1) No contact, zero damage to the substrate. Because there is no direct physical contact during the cleaning process, there is no physical damage to the workpiece.
(2) Wide applicability, good cleaning effect. The laser has good directivity, can accurately position the workpiece part, so as to carry out selective operation, is not limited by the surface topography of the workpiece, and can adapt to a variety of cleaning objects; The cleaning process can be accurately controlled to achieve the desired cleaning effect.
(3) Easy to use and flexible, easy to operate. Laser cleaning handheld series equipment is not only mobile, but also very convenient to carry, the working head is light, and can be operated for a long time; Automatic cleaning equipment can be installed in the motion platform, robot and other motion mechanism, to achieve stable automatic cleaning, simple operation.
(5) Green environmental protection, cost-effective. Only electricity is consumed in the cleaning process, and the long-term cleaning cost is low.
