Laser cleaning machine

Laser cleaning machine

Laser cleaning machine is a device that uses a high-energy-density laser beam to act on the surface of the workpiece to remove dirt, rust, coatings and other attachments on the surface. The following is a detailed introduction to it:

1. Working principle

Laser cleaning is based on the principle of interaction between laser and matter. When a high-energy-density laser beam is irradiated on the surface of an object, the surface material will absorb the energy of the laser. For dirt, rust layer, etc., the laser energy causes them to expand, vaporize or vibrate instantly due to heat, thereby separating from the surface of the substrate to achieve the purpose of cleaning. Different attachments and substrates have different characteristics of laser absorption and reflection, which also enables the laser to selectively remove target attachments without damaging the substrate material as much as possible.

2. Advantages

Good cleaning effect: It can accurately remove various pollutants, including oil, rust, paint, oxide layer, etc., can achieve a very high cleanliness standard, and can effectively remove some stubborn stains that are difficult to handle with traditional cleaning methods.

Non-contact cleaning: The laser beam acts on the surface of the object to be cleaned through space without direct contact with the object, avoiding mechanical damage such as scratches and wear caused by the cleaning tool on the surface of the object, which is particularly suitable for cleaning some delicate and fragile parts.

Selective cleaning: The cleaning area and depth can be accurately selected according to the different absorption characteristics of the laser by the attachment and the base material, and only the part that needs to be cleaned is removed, with almost no impact on the surrounding areas that do not need to be cleaned.

Environmentally friendly and pollution-free: The entire cleaning process generally does not require the use of chemical cleaning agents, and does not produce a large amount of pollutants such as chemical waste liquid. It is environmentally friendly and reduces the cost and trouble of subsequent treatment of chemical waste.

High flexibility: The laser cleaning head can be flexibly moved by devices such as robotic arms, which can adapt to the cleaning needs of workpieces of different shapes, sizes and complex structures, and the parameters of the laser can be easily adjusted to cope with different cleaning tasks.

3. Disadvantages

High equipment cost: The research and development and manufacturing of laser cleaning machines involve advanced laser technology, etc., resulting in relatively high purchase costs, which may cause some small enterprises or users with limited budgets to face greater economic pressure when purchasing.

High requirements for operators: Operators are required to have certain laser knowledge and relevant operating skills, and understand laser safety protection regulations to ensure that they can effectively complete the cleaning task during use and ensure the safety of themselves and the surrounding environment.

Relatively limited cleaning efficiency: Although it performs well for some small-area, high-precision cleaning tasks, for large-area, large-volume cleaning work, its cleaning speed may not be as fast as some traditional large-scale cleaning equipment (such as large high-pressure water cleaning equipment, etc.), and it may take a long time to complete the entire cleaning work
