The use of industrial laser cleaning technology
time:2024-07-26  Publisher:Wuhan SC Laser  click:9

Laser cleaning technology is the use of nanosecond or picosecond pulsed laser irradiation to the surface of the workpiece to be cleaned, so that the surface of the workpiece absorbs the focused laser energy in an instant, forming a rapidly expanding plasma (highly ionized unstable gas), so that the surface of the oil, rust, dust, coating, oxidation layer or film layer gasification or stripping, etc. A cleaning method to efficiently remove surface attachments.


Applicable substrate

 

In the field of industrial applications, laser cleaning objects are divided into substrate and cleaning materials in two parts, the substrate is mainly a variety of metals, semiconductor wafers, ceramics, magnetic materials, plastics and optical components and other materials surface pollution layer, cleaning mainly for the industrial field of rust, paint, oil, film/oxide layer and cleaning resin, glue, dust and slag and other widely used needs.


Advantages of laser cleaning

 

At present, the cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but under the constraints of environmental protection and the requirements of the high-precision market, its application is greatly limited. The laser cleaning machine has obvious advantages in various industries.

1) Automated assembly line: Laser cleaning machine can be integrated with CNC machine tools or robots to implement remote control cleaning, which can realize the automation of equipment, forming product assembly line operation and intelligent operation.

 

2) Accurate positioning: The use of optical fiber transmission guide laser to make it flexible, through the built-in scanning mirror to control the spot for high-speed movement, easy to shape parts, holes, grooving and other traditional cleaning methods difficult to reach the corner of the non-contact laser cleaning process.

 

3) No damage: a short time of impact will not warm the metal surface, no damage to the substrate.

 

4) Good stability: The pulsed laser used in laser cleaning machine has a very long service life, usually up to 100,000 hours of service life, stable quality and good reliability.

 

5) No environmental pollution: no chemical cleaning agent does not produce cleaning waste liquid, the pollutant particles and gases generated in the laser cleaning process can be simply collected and purified through the portable exhaust fan to avoid environmental pollution.

 

6) Low maintenance cost: there is no consumable consumption during the use of laser cleaning machine, low operating cost, only need to regularly clean or replace the lens in the later period, low maintenance cost and close to maintenance-free.

 

Application industry

 

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



Wisco Huagong Laser has launched a series of laser cleaning products with different power, efficiency and structure: low power (50-200W) laser cleaning machine, medium power (300-500W) laser cleaning machine, high power (800-1600W) clamping laser cleaning machine.

 

Medium and low power cleaning machine can be customized handheld and clamping, cleaning flexibility, can be cleaned for different dirt, complex parts.


High power clamping laser cleaning machine is suitable for mass production or large objects or large area production environment of efficient equipment, more intelligent, high efficiency, high stability of the production line, can form product assembly line operation.


The whole set of laser cleaning equipment adopts non-standardized design, which can adapt to different places and meet the cleaning needs of different industries and different working conditions. Long-term continuous operation of the laser ensures the stability and service life of the equipment.
