Development status of laser cleaning technology

For daily industrial products and professional industrial products, one or several technologies and processes in surface treatment technology are used to realize the functions required by product design or market.

In the process of electroplating, phosphating, spraying, welding, packaging and integrated circuit assembly of industrial products, it is necessary to remove contaminants such as grease, dust, rust, residual solvents, adhesives and other pollutants on the surface to ensure the quality of the next process. .At present, the cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but their applications are greatly limited under the constraints of environmental protection and the requirements of the high-precision market.

Mechanical methods cannot meet the requirements of high cleanliness cleaning;

The chemical cleaning method is easy to cause environmental pollution, and the cleanliness obtained is also very limited; especially when the dirt composition is complex, multiple cleaning agents must be used for repeated cleaning to meet the surface cleanliness requirements;

Although the ultrasonic cleaning method has a good cleaning effect, it is powerless to sub-micron dirt particles. The size of the cleaning tank limits the scope and complexity of the parts to be machined, and drying of the workpiece after cleaning is also a big issue.

It must be admitted that my country’s manufacturing industry is now in a big but not strong situation, especially in the field of surface treatment technology. Modern manufacturing requires the support of powerful surface treatment technology. The backward production capacity of my country’s surface treatment industry needs to be replaced and filled by advanced technologies and processes. This is an important challenge faced by my country’s manufacturing industry in the process of turning from large to strong. The challenges faced by the surface engineering industry have brought great pressure to the industry, but also brought great opportunities.

With the advent of the era of Industry 4.0, some new smart industrial products have entered the market, and these new products must use surface treatment technology without exception, and it is necessary to convert the settled production capacity into advanced productivity. Laser cleaning technology is a new cleaning technology that has developed rapidly in the past ten years. Due to its many advantages, it is gradually replacing traditional surface treatment cleaning technology in many fields. It can adapt to the cleaning of various surface pollutants, has minimal environmental pollution, and can not damage the substrate. At present, this method has become a supplement and extension of traditional cleaning methods, and has shown broad application prospects due to its many inherent advantages.

Compared with the traditional cleaning process, laser cleaning technology has the following characteristics:

It is a kind of “dry” cleaning, which does not require cleaning fluid or other chemical solutions, and its cleanliness is much higher than that of chemical cleaning processes;

A wide range of decontamination and applicable substrates;

By adjusting the laser process parameters, the contaminants can be effectively removed without damaging the surface of the substrate, and the surface can be restored as new;

Laser cleaning can easily realize automatic operation and reduce labor;

Laser cleaning has high efficiency and saves time;

Laser decontamination equipment can be used for a long time with low operating cost;

Laser cleaning technology is a “green” cleaning process, and the eliminated waste is solid powder, small in size, easy to store, and basically does not pollute the environment.
