The laser cleaning technology in the laser cleaning machine refers to the use of high-energy laser beams to irradiate the surface of the workpiece to cause the dirt, rust or coating on the surface to evaporate or peel instantly, which can effectively remove the surface attachments or surface coatings to achieve cleanliness purpose. This technology is often used in industrial manufacturing, and in order to ensure the quality of the product during the production process, it is necessary to remove dirt, grease, dust, rust and other contaminants on the surface of the product. The following is to show you the industry application of laser cleaning machine.
In the process of electroplating, phosphating, spraying, welding, packaging and integrated circuit assembly of industrial products, grease, dust, rust and residual solvents, adhesives and other dirt on the surface must be removed to ensure the quality of the next process . The current cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but their application is greatly restricted under the constraints of environmental protection and the requirements of the high-precision market. The laser cleaning machine has obvious advantages in various industries.
1. Mold cleaning
In the production process, tire mold cleaning must be rapid and reliable to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc. These methods take a long time to clean and easily damage the mold. Since the laser cleaning method can be connected with optical fiber to guide the light to the dead corner of the mold or the part that is not easy to clean, it is more convenient to use, and the rubber will not vaporize, so it will not generate toxic gas and affect the safety of the working environment.
2. Cleaning of old aircraft paint
After the aircraft has been working for a period of time, the surface of the aircraft needs to be repainted, so it is necessary to find a way to remove the old paint. The traditional mechanical paint removal method can easily damage the metal surface of the aircraft and bring hidden dangers to the aircraft. Using the washing machine will not damage the surface.
3. Cleaning of building exterior walls
The exterior walls of many office buildings have cleaning problems. Under normal circumstances, manpower is used to clean the exterior walls, while the laser cleaning system uses optical fibers to clean the exterior walls of the building, so machine cleaning is better than manual cleaning. It is more efficient.
4. Cleaning in the electronics industry
The electronics industry will use lasers to remove oxides, and the electronics industry is suitable for lasers to remove oxides. Before the circuit board is soldered, the component pins must be thoroughly deoxidized to ensure the effect of electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high, only one stitch of laser irradiation.
5. Deesterification cleaning in precision instrument industry
The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and anti-corrosion on the parts, usually using chemical methods, and chemical cleaning often has residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The removal of contaminants is achieved by shock waves. The explosive gasification of the thin oxide layer on the surface of the parts forms a shock wave, which leads to the removal of dirt instead of mechanical interaction. The material is thoroughly deesterified and used for the cleaning of mechanical parts in the aerospace industry. Laser cleaning can also be used to remove oil esters in mechanical parts processing.
6. Pipeline cleaning in nuclear power plant reactor
The laser cleaning system is also used in the cleaning of pipelines in nuclear power plant reactors. It uses optical fibers to introduce high-power laser beams into the reactor to directly remove radioactive dust, and the cleaned materials are easy to clean. And because it is operated remotely, the safety of the staff can be ensured.
