What Is Laser Cleaning ?
Laser cleaning is a technology that uses a focused laser to act on the surface of a material to rapidly vaporize or peel off the contaminants on the surface, so as to clean the surface of the material. Compared with various traditional physical or chemical cleaning methods, laser cleaning has the characteristics of no contact, no consumables, no pollution, high precision, no damage or small damage, and is an ideal choice for a new generation of industrial cleaning technology.
How Does A Laser Cleaning Machine Work?
The principle of laser cleaning is to use high-frequency high-energy laser pulses to irradiate the surface of the workpiece, and the coating layer can instantly absorb the focused laser energy, so that the oil stains, rust spots or coatings on the surface can be evaporated or peeled off instantly, and the surface attachments or coatings can be removed efficiently at high speed. The cleaning method of the surface coating, while the laser pulse with very short action time, will not harm the metal substrate under the appropriate parameters.
What Are the Features of the Laser Cleaning Machine?
1) Automated assembly line: The laser cleaning machine can be integrated with CNC machine tools or robots to implement remote control and cleaning, which can realize the automation of equipment, form product assembly line operations, and operate intelligently.
2) Accurate positioning: use optical fiber transmission to guide the laser to make it flexible, and control the light spot to move at high speed through the built-in scanning galvanometer, which is convenient for non-contact hard-to-reach parts such as special-shaped parts, holes, and grooves that are difficult to reach by traditional cleaning methods. ground laser cleaning.
3) No damage: A short-term impact will not heat the metal surface and cause no damage to the substrate.
4) Good stability: The pulsed laser used in the laser cleaning machine has a long service life, usually up to 100,000 hours, with stable quality and good reliability.
5) No environmental pollution: no chemical cleaning agents are required and no cleaning waste liquid is generated. The pollutant particles and gases generated during the laser cleaning process can simply be collected and purified by a portable exhaust fan to avoid environmental pollution.
6) Low maintenance cost: no consumables are consumed during the use of the laser cleaning machine, and the operating cost is low. In the later stage, only the lens needs to be cleaned or replaced regularly, and the maintenance cost is low, which is close to maintenance-free.
The Application of the Laser Cleaning Machine
In the field of industrial applications, laser cleaning objects are divided into two parts: substrates and cleaning objects. Substrates mainly include surface contamination layers of various metals, semiconductor wafers, ceramics, magnetic materials, plastics and optical components; cleaning materials mainly include rust removal, paint removal, oil removal, film removal/oxide layer removal for industrial fields And cleaning resin, glue, dust slag and other wide application needs.
Typical applications of laser cleaning include: mold cleaning, industrial rust removal, old paint and film removal, pre-welding and post-weld treatment, ester removal of precision parts, decontamination and oxide layer removal of electronic components, cultural relics cleaning, etc.
Widely used in metallurgy, mold, automobile, hardware tools, transportation, construction appliances, machinery and other industries.
