In the field of industrial production, machinery and equipment have been in service for a long time, and a large amount of oil pollution, waste paint layer, rust and carbon deposits have accumulated on the surface of parts and components. The overhaul of the generator set is a very time-consuming and labor-intensive project. Due to the extremely complex large surface of the workpiece, the traditional cleaning process has many disadvantages, and the dead corners cannot be completely cleaned. Due to the extremely small beam size of the laser beam, the dead space of complex workpieces becomes easy. The surface of the workpiece is irradiated with a laser beam to instantly evaporate or peel off the dirt, rust spots, particles or coatings on the surface, so as to achieve a clean process.
Advantages of laser cleaning:
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 agent is required and no cleaning waste liquid is produced. The pollutant particles and gases generated during the laser cleaning process can be simply 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.
Compared with traditional cleaning methods, laser cleaning can achieve fully automated operation. It has the advantages of high work efficiency, low cost, no pollution to the environment, no damage to the substrate and a wide range of materials. It fully conforms to the green and environmentally friendly processing concept and is the most reliable and effective cleaning method at present. Although laser cleaning has not completely replaced traditional cleaning methods at present, as the country's awareness of environmental protection such as energy saving and emission reduction in manufacturing increases, laser cleaning will gradually enter people's lives with its unique advantages.
