Chengdu MRJ-laser Technology Co., Ltd. is a technical expert company specializing in laser application. The company is mainly engaged in research and development, production and application of fiber output YAG pulse laser, fiber output semiconductor pulse laser, high power semiconductor continuous laser and laser intelligent equipment.
With the advent of the Industry 4.0 era, some new intelligent industrial products have entered the market, and these new products, without exception, require the use of surface treatment technology, and need to transform the settled capacity into advanced productivity. Laser cleaning technology is a new type of cleaning technology developed rapidly over the past decade. It has gradually replaced traditional surface treatment cleaning processes in many fields due to its many advantages. It can adapt to the cleaning of various surface dirt, minimal environmental pollution, can do without damage to the substrate. At present, this method has become a supplement and extension of the traditional cleaning method, and has shown a broad application prospect due to its inherent many advantages.
Daily industrial products and professional industrial products must use one or more of the surface treatment technologies to achieve the functions required by the product design or market.
In the process of electroplating, phosphating, spraying, welding, packaging and integrated circuit assembly of industrial products, the grease, dust, rust, and residual solvents, adhesives, etc. on the surface must be removed to ensure the quality of the next process. .
Cleaning methods that are widely used in the cleaning industry today include mechanical cleaning methods, chemical cleaning methods, and ultrasonic cleaning methods, but their application is greatly limited due to environmental protection constraints and high-precision market requirements.
The specific reasons are as follows:
First, the mechanical method can not meet the high cleanliness cleaning requirements;
Second, chemical cleaning methods can easily lead to environmental pollution, and the degree of cleanliness obtained is also very limited; especially when the dirt components are complex, multiple cleaning agents must be used to repeatedly clean before they can meet the requirements of surface cleanliness;
Third, the ultrasonic cleaning method, although the cleaning effect is good, but the submicron level of particle cleaning can do nothing. The size of the cleaning tank limits the scope and complexity of the processing parts, and the drying of the workpiece after cleaning is also a major problem.
Laser processing technology takes full advantage of the laser's good directionality, high brightness, and transient nature. It is a special processing technology that uses laser as a processing heat source, including laser welding, laser cutting, laser hole making, and laser surface processing. Because lasers have good monochromaticity, directionality, coherence, and high brightness, laser processing has many advantages over other processing methods, such as no contact, no "cutting force" processing, high hardness, high Brittleness, high melting point material processing, high flexibility, high controllability processing, high precision, high quality, high efficiency processing, etc. After continuous development in recent decades, laser technician technology has formed a relatively systematic and complete technical group, including welding, cutting, hole making, marking, engraving, cladding, surface heat treatment, alloying, cleaning, impact strengthening, and increased manufacturing. And laser micro-nano processing.
