Oil stains are the dirt formed by the long-term accumulation of oil during the evaporation process. In industrial production, oil stains are generally prone to accumulation. The existing cleaning methods mainly use chemical cleaning, spraying a cleaning agent on the surface of the oil stains, and using a cleaning agent to dissolve and disperse the oil stains. The production cost of the cleaning agent is high, the cleaning time is long, the cleaning cost is relatively high, and it is harmful to the human body. In addition, there is a way of removing oil stains by mechanical friction, which is time-consuming and labor-intensive, and easily damages the surface of the workpiece.

　Laser cleaning equipment is an innovation in the cleaning method of industrial oil stains. It overcomes the shortcomings of traditional cleaning requiring cleaning agents, complicated cleaning processes, and long cleaning hours, and realizes non-toxic and harmless green cleaning. Its specific beneficial effects are:

　　1. Green cleaning: This equipment adopts a "green" cleaning method without the use of any cleaning agent, which can easily solve the problem of environmental pollution caused by chemical cleaning.

　　2. Non-contact cleaning: The traditional cleaning method is often contact cleaning, which has a mechanical force on the surface of the cleaned object, damaging the surface of the object or the cleaning medium adhering to the surface of the cleaned object, which cannot be removed, resulting in secondary pollution. The non-abrasive and non-contact nature of this equipment makes these problems easy to solve.

　　3. Safe operation: Due to the characteristics of light, it can clean parts that are not easily accessible by traditional methods.

　　4. High cleanliness: This equipment can remove various types of contaminants from the surface of various materials, achieving cleanliness that cannot be achieved by conventional cleaning, and can also selectively clean the surface of the material without damaging the surface of the material.

　　5. High cleaning efficiency: Laser cleaning can achieve instant cleaning results, with high efficiency and time savings.

　　6. Low cost: The laser cleaning system can be used stably for a long time, with low maintenance rate and low operating costs.
