Application of industrial laser cleaning technology

Laser cleaning technology is the use of nanosecond level or picosecond pulse laser irradiation for cleaning the surface of workpiece, the workpiece surface absorb laser energy focus in an instant, to make rapaid increase plasma (Highly ironized unstable gas), the slag, dust, grease, rust stain on the surface of the coating, such as oxidation layer or film gasification or stripping, so as to efficiently remove attachments to clean surface.

Suitable substrate

In the field of industrial applications, laser cleaning object is divided into two parts of the base material and cleaning, and base material mainly include all kinds of metal, semiconductor chips, ceramics, magnetic materials, plastics and optical components such as material layer surface contamination, cleaning the content mainly includes industrial field oriented derusting, paint, oil removal, in addition to the film/slag oxidation layer and clean up resin, rubber, dust etc widely application requirements.

Advantages of laser cleaning

Now.Laser cleaning is widely used in mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method, but in the environmental protection constraints and the requirements of the high precision market, its application is greatly limited. And laser cleaning machine in the industry application advantage is obvious.

1) Automatic production line: The laser cleaning machine can be integrated with CNC machine tools or robots to carry out remote control cleaning, which can realize the automation of equipment, form production line operation and intelligent operation.

2) Setting Accuracy: the optical fiber transmission is used to guide the laser to make it flexible, and the built-in scanning galvanometer is used to control the light spot for high-speed movement, which is convenient for non-contact laser cleaning of corners that are difficult to reach by traditional cleaning methods, such as irregular parts, holes and grooves.

3) No damage: A short time of impact will not make the metal surface warm, and there is no damage to the substrate.

4) Good stability: the pulse laser used in the laser cleaning machine has a long service life, usually up to 100,000 hours, stable quality, good reliability.

5)Environmental protection: There is no need for chemical cleaning agents to produce waste cleaning liquid. Pollutant particles and gases generated in the laser cleaning process can be simply collected and purified through a portable exhaust fan to avoid environmental pollution.

6) Low maintenance cost: there is no consumable material consumption during the use of the laser cleaning machine, and the operating cost is low. In the later stage, the lens only needs to be cleaned or replaced regularly, with low maintenance cost and close to no maintenance.

Application industry

Typical applications of laser cleaning include: die cleaning, industrial rust removal, paint removal and film layer, pre-treatment and post-treatment before welding, ester removal of precision parts, electronic components decontination oxidation layer, cultural relic cleaning, etc. Widely used in metallurgy, mold, automobile, hardware tools, transportation, construction appliances, machinery and other industries.
