Laser cleaning machine is a device that uses laser technology for cleaning. Its working principle is to use the high energy and high density of the laser beam to evaporate or peel off dirt and impurities from the surface of the object, thereby achieving the purpose of cleaning. The core components of the laser cleaning machine are the laser generator and optical system.
How does a laser cleaning machine work?
The laser generator generates a high-energy laser beam, and the optical system focuses the laser beam onto the surface of the object to form a very small cleaning spot. When the laser beam irradiates the surface of the object, dirt and impurities will absorb the laser energy, produce thermal expansion and thermal decomposition, and thus evaporate or peel off. The cleaning points move across the surface of the object, continuously removing dirt and impurities until the entire surface is cleaned. It can effectively and quickly remove attachments and excess coating from workpieces, and is considered the most effective solution for workpiece cleaning.
High temperature vaporization:The highly concentrated laser beam can generate very high heat energy around the spot, so dirt can be quickly vaporized or peeled off instantly;
Swell and fall off:The scattering of the laser beam is small and the direction is stable. We can adjust the energy density of the laser by controlling the laser beam spot with different diameters, so that the dirt is heated and then changed. When the expansion force of dirt is greater than the adsorption force of dirt to the substrate, detachment and falling will occur.
Shock off:The laser cleaning beam can produce a high-frequency ultrasonic wave on the solid surface, thereby causing mechanical resonance to quickly break and fall off the dirt.
What materials can be cleaned with laser cleaning?
It can be used to remove coatings on metal or glass surfaces and remove paint quickly. It can not only remove all the paint, but also clean the surface paint layer by layer; quickly remove rust and various oxides on metal surfaces; remove grease, resin, and glue. , dust, stains, production residues; metal surface roughening; rust and oil removal of automobile parts before welding, and oxide and stain cleaning after welding; mold cleaning, such as tire molds, electronic molds, food molds; precision parts production Removal of oil stains after processing; rapid cleaning of nuclear power component maintenance; oxide treatment, paint removal, and rust removal during aerospace weapons, ship production or maintenance; metal surface cleaning in small spaces; cultural relic cleaning, rock cleaning, and building exterior surface cleaning .
What are the characteristics of laser cleaning?
Environmental friendly
Environmental friendly:Laser cleaning is a “green” cleaning method that does not require the use of any chemicals or cleaning fluids. The cleaned waste materials are basically solid powder. They are small in size, easy to store, and recyclable. It can easily solve the problems caused by chemical cleaning. Environmental Pollution;
Non contact：Traditional cleaning methods are often contact cleaning, which exerts mechanical force on the surface of the object to be cleaned, damaging the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned and cannot be removed, resulting in secondary pollution. Laser cleaning is non-abrasive and non-abrasive. Contact solves these problems;
Can be automated:Laser can be transmitted through optical fibers and cooperated with robot hands and robots to facilitate long-distance operations and clean parts that are difficult to reach with traditional methods. This can ensure the safety of personnel when used in some dangerous places;
Good cleaning effect:Laser cleaning can remove various types of contaminants from the surface of various materials, achieving a level of cleanliness that conventional cleaning cannot achieve. It can also selectively clean contaminants on the material surface without damaging the material surface;
Efficient:Laser cleaning is highly efficient and saves time;
Low cost of use:Although the initial one-time investment in purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time and has low operating costs.
Compared with traditional cleaning methods such as mechanical, chemical corrosion, and strong impact, laser cleaning technology has the advantages of being more efficient, faster, and lower cost. Not only will it not cause any form of damage to the base material, but in today’s era when the whole world pays attention to environmental protection, the use of laser cleaning machine equipment will not cause pollution to our environment, and will not cause harm to the operator’s body. The future is a major trend in industrial cleaning.
