The Application Of Laser Cleaning Machine
May 31, 2018

Laser cleaning can be used not only to clean organic contaminants, but also to clean inorganic materials, including metal rust, metal particles, and dust. The following describes some practical applications. These technologies have been very mature and have been widely used.

1. mold cleaning:

Every year, tire manufacturers in the world manufacture hundreds of millions of tires, and the tire molds in the production process must be quickly and reliably cleaned to save downtime. Conventional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, but these methods usually must be cooled in a hot mold for several hours, then moved to the cleaning equipment for cleaning, cleaning takes a long time, and easy to damage the accuracy of the mold Chemical solvents and noise can also cause problems such as safety and environmental protection. The use of laser cleaning methods, because the laser can be transmitted using optical fiber, so it is very flexible in use; because the laser cleaning method can be used to connect the optical fiber to the blind corner of the die or difficult to clean the parts to be cleaned, so easy to use; due to rubber and Without gasification, no toxic gas will be produced, which will affect the safety of the working environment. The technology of laser cleaning tire molds has been widely adopted in the tire industry in Europe and America. Although the initial investment cost is high, the receipts can be quickly obtained by saving standby time, avoiding mold damage, working safety, and saving raw materials. According to the cleaning test performed by the Quantel LASERLASTE laser cleaning system on the production line of Shanghai Shuangqin Trucking Tire Co., it is shown that it is only necessary to clean the mold of a large-scale truck tire online in 2 hours. Compared with conventional cleaning methods, the economic benefits are obvious.

The anti-adhesive elastic film layer on food industry moulds needs to be replaced regularly to ensure hygiene. The use of laser cleaning without chemicals is also particularly suitable for this application.

2. Weapon Equipment Cleaning:

Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select cleaning sites to realize the automation of cleaning. The use of laser cleaning not only has a higher degree of cleanliness than the chemical cleaning process, but also has little damage to the surface of the object. By setting different parameters, Quantel LASERLASTE can also form a dense oxide protective film or molten metal layer on the surface of metal objects. , improve the surface strength and corrosion resistance of the laser. The waste removed does not substantially pollute the environment and can also be operated remotely, effectively reducing the health damage to the operators.

3. removal of aircraft paint:

In Europe, the laser cleaning system has long been used in the aviation industry. After the surface of the aircraft has been repainted after a certain period of time, the original paint must be completely removed before painting. The traditional method of mechanical removal of paint is likely to cause damage to the metal surface of the aircraft, causing hidden dangers to safe flight. If multiple laser cleaning systems are used, the paint on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.

4. Cleaning of external walls of buildings:

With the rapid development of China's economy, more and more skyscrapers have been set up, and the problem of cleaning the external walls of buildings has become increasingly prominent. LASERLASTE laser cleaning system provides good cleaning of external walls of buildings through optical fibers up to 70 meters in length. The solution is that it can effectively clean various kinds of pollutants on stone, metal and glass, and it is much more efficient than conventional cleaning. It can also remove dark spots and stains on various stone materials of buildings. LASERLASTE laser cleaning system has been used to clean building and stone monuments in Shaolin Temple of Shaoshan Mountain. It shows that the use of laser cleaning is very effective in protecting the appearance of ancient buildings.

5. Cleaning in the Electronic Industry

The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, which is particularly suitable for the use of laser deoxidation before circuit board soldering. Component pins must be completely de-oxidized to ensure optimal electrical contact during decontamination. Do not damage the pins yet. Laser cleaning can meet the requirements of use, and the efficiency is very high. Only one laser beam is needed for one pin.

6. Accurate deesterification in the precision machinery industry:

The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and anti-corrosion on the parts, usually by chemical methods, while the chemical cleaning often still has residues. Laser deesterification can completely remove the esters and mineral oil without damaging the surface of the parts. The removal of contaminants is accomplished by shock waves. The explosive vaporization of the thin oxide layer on the surface of the part forms a shock wave, resulting in the removal of contaminants rather than a mechanical interaction. The material is completely deesterified for use in the cleaning of aerospace industrial machinery parts. Oil ester removal in the machining of mechanical parts can also be cleaned by laser.

7. Nuclear power plant reactor pipe cleaning:

The laser cleaning system is also used for the cleaning of pipelines in reactors of nuclear power plants. It uses optical fiber to introduce a high-power laser beam into the reactor and directly removes radioactive dust. The cleaned material is easy to clean. And because it is a long-distance operation, staff safety can be ensured.

In summary, laser cleaning plays an important role in many fields, such as automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building exterior wall cleaning, cultural relics protection, circuit board cleaning, and precision parts. Processing and manufacturing, liquid crystal display cleaning, chewing gum residue removal and other areas can play an important role.
