Working principle of laser cleaning machine

A laser cleaning machine is an advanced equipment that uses laser technology for surface cleaning. Its working principle is based on the high energy and high controllability of the laser. The laser beam instantaneously irradiates the surface of the object to excite the pollutants on the target surface, causing them to instantly heat up and evaporate or vaporize, thereby achieving the cleaning effect. The basic steps are as follows:

Absorption and transmission of energy: The laser cleaning machine uses a laser beam of a specific wavelength to irradiate the target surface, and the contaminants on the surface of the object to be cleaned absorb the laser energy. Through the absorption of laser energy, dirt on the target surface becomes affected.
Photothermal effect: Pollutants irradiated by laser receive extremely high energy input in an instant, causing local heating. Reach or even exceed its evaporation or gasification temperature, thereby causing phase change.
Evaporation and gasification: The rising temperature of pollutants causes part or all of them to evaporate or gasify. During this process, the molecules of pollutants break away from the surface of the object under the action of the laser beam and become a gas, thereby removing impurities and dirt originally attached to the surface.
Removal and collection: After laser irradiation, contaminants are released from the target surface in the form of gas. The target surface to be cleaned is exposed, creating a cleaning effect.

Laser cleaning machines achieve efficient cleaning of target surfaces through photothermal effects. Their application fields cover many key industries, providing efficient, environmentally friendly, and accurate solutions for cleaning work.

Application of laser cleaning machines in the manufacturing industry

As an efficient and environmentally friendly cleaning technology, laser cleaning machines have been widely used in the manufacturing industry. Its unique working principle and advantages make it an indispensable tool in various manufacturing processes. The following are the main application areas of laser cleaning machines in manufacturing:

Automobile manufacturing industry

With the continuous development of the automobile manufacturing industry, laser cleaning machines, as an efficient and environmentally friendly cleaning technology, are gradually becoming an important tool in the automobile manufacturing process. Its unique working principle and precise cleaning effect make it play a key role in many aspects.

Car surface cleaning: During the car manufacturing process, various stains, paint spray residues, and other impurities will be attached to the car body surface. Traditional cleaning methods make it difficult to completely remove these contaminants. The laser cleaning machine can accurately remove these contaminants through the action of high-energy laser beams, providing a clean basis for subsequent painting and assembly work.
Engine parts cleaning: During operation, automobile engine parts will be affected by high temperature, high pressure, grease, and other factors, causing dirt to accumulate on the surface of the parts. Laser cleaning machines can be used to clean engine parts, such as cylinder heads, pistons, etc., to keep engine parts in good working condition.
Body painting preparation: In the final stage of automobile manufacturing, laser cleaning machines can also be used to prepare the body for painting. Cleaning the car body surface can ensure that the paint adheres more firmly, improves the uniformity and quality of the paint, and makes the final car look more beautiful.

Electronic Manufacturing

The electronics manufacturing industry has extremely high requirements for cleanliness and precision, so laser cleaning machines play an important role in this field. Its high-energy laser beam and precise control characteristics make it an ideal tool in electronic manufacturing, and its applications cover many aspects:

Semiconductor chip manufacturing: The manufacturing of semiconductor chips requires extremely high surface cleanliness. The laser cleaning machine can efficiently clean the chip surface through a laser beam without damaging the chip. This is crucial to ensure the performance of the chip and reduce the defect rate during the manufacturing process.
Substrate preparation in LED production: In the manufacturing of LEDs (light-emitting diodes), the cleanliness of the substrate surface directly affects the performance of the LED device. Laser cleaning machines can be used to clean the surface of LED substrates, remove contaminants that may affect the luminous effect, and improve the luminous efficiency and stability of LEDs.
Electronic component cleaning: In the manufacturing process of electronic components, the surfaces of various components often need to be rigorously cleaned. Laser cleaning machines can efficiently clean contaminants on the surface of electronic components and prevent the components from being affected by the external environment during use.
Circuit board cleaning: Welding, printing, and other processes on circuit boards are prone to produce residues, which may cause circuit short circuits or signal instability. Laser cleaning machines can efficiently clean circuit board surfaces through precise laser beam control.
Laser etching and area coating: Laser cleaning machines can not only clean surfaces but can also be used to laser etch and remove special coatings covering the surface of electronic devices. For example, in the manufacturing process of integrated circuits, the chip surface needs to be precisely etched and decoated.

Application of laser cleaning in cultural relic protection

Laser cleaning is widely used in cultural relics protection. Its efficient, non-contact, and precise cleaning characteristics make it an important tool in the field of cultural relics protection. The following are the main applications of laser cleaning machines in cultural relics protection:

Ancient building surface cleaning

The surfaces of ancient buildings tend to accumulate dust, stains, and other pollutants, and traditional cleaning methods may cause damage to building materials. Through precise control of high-energy laser beams, laser cleaning machines can remove contaminants on the surface of ancient buildings while protecting the integrity of the building itself and avoiding possible damage caused by traditional cleaning methods.

Sculpture and stone carving cleaning

Sculptures and stone carvings in cultural relics are often corroded by rain, weathering, and pollutants in the air, and require regular cleaning. Laser cleaning machines can accurately remove attachments on the surface of sculptures and stone carvings and restore their original artistic appearance without damaging the details and texture of the sculpture’s surface.

Ceramic and glassware cleaning

Dirt on the surface of ceramic and glass objects is often difficult to completely remove, but laser cleaning machines can clean these objects at a microscopic level, remove attached dust and stains, and restore their original color and luster.

Metal artifact cleaning

Metal cultural relics such as bronzes and copperware may oxidize and rust during long-term use and storage. Laser cleaning machines can efficiently remove oxides from metal surfaces and restore the original luster of metal artifacts while avoiding mechanical scratches that may be caused by traditional cleaning.
