Working principle of laser cleaning machine

Some traditional industrial cleaning machines will cause damage to objects during the cleaning process, some have certain limitations, and some have serious environmental pollution. In order to solve these thorny problems, laser cleaning machines came into being. Laser cleaning can not only clean organic contaminants, but also inorganic substances, including metal rust and metal particles. The following describes the cleaning principle of the laser cleaning machine.

Fiber Laser Cleaning MachineWhen there are sub-micron contamination particles on the workpiece surface, these particles are often tightly attached and cannot be removed by conventional cleaning methods, but it is very effective to clean the workpiece surface with laser irradiation. In addition, since the cleaning of the workpiece by the laser is non-contact, it is very safe to clean the precision workpiece or its fine parts, and its accuracy can be guaranteed. Therefore, laser cleaning machines have unique advantages in the cleaning industry.

The principle of laser rust removal is that the rust layer will evaporate instantly under the action of high temperature. After the plasma is separated, due to its high reflectivity, the rust removal part will not be damaged even if it is exposed to the laser. The underlying metal lights up. The laser descaling method is effective and safe, even perfectly cleaning the corners of parts such as letters and bolts. Therefore, it can be easily dealt with whether it is difficult to remove rust or not. Rust has nowhere to hide as long as light can reach it.

Each laser pulse removes a certain thickness of the contamination layer. If the contamination layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important consequence of the two thresholds is clean self-control. Light pulses with an energy density above the first threshold will reject contaminants until they reach the substrate material. However, since its energy density is below the destruction threshold of the substrate material, the substrate is not damaged.

Cleaning application of laser cleaning machine on rubber mold

The cause of the surface contamination of the rubber product mold was determined, and the main adsorption force between the rubber particles on the mold surface and the substrate was determined to be the van der Waals force. The practical application of laser cleaning rubber product mold technology is studied. After using the laser cleaning technology to clean the sealed mold, it is not difficult to see the advantages of the laser cleaning technology. Laser cleaning will be the mainstream of mold cleaning in the future, and laser cleaning technology will definitely play an important role in the mold industry. Jiabang Laser has more than ten years of experience in R&D and production, and is in an industry-leading position in technology and integration. Since its establishment, the company has been focusing on the development of laser technology and the development needs of customers, and is committed to providing every customer with complete material processing solutions.

Traditional chemical cleaning method, high pressure water cleaning method, dry ice method, mechanical grinding, etc. Before using the laser cleaning equipment, the customer also tried to brush the glue layer on the surface of the rubber mold with a wire brush, but the effect was not good. This kind of cleaning has the disadvantages of high labor intensity, low power, low safety factor and high cost. Laser cleaning can solve this problem well. Laser cleaning is the use of high-frequency high-energy laser pulses to irradiate the surface of the workpiece. The coating can instantly absorb the concentrated 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. cleaning method, while the laser pulses with very short action time will not damage the metal substrate under the appropriate parameters.

The laser beam emitted by the laser cleaning machine is irradiated on the surface of the plastic mold, and the impurities on the surface absorb the concentrated laser energy, causing it to evaporate instantly or peel off from the surface of the plastic mold. The laser cleaning equipment is simple to operate, easy to learn and use. In traditional cleaning methods, different personnel operations may cause different cleaning effects. However, by setting certain parameters for laser cleaning, the workpiece can be cleaned, and the cleaning effect is general.
