Working principle of laser cleaning machine Laser cleaning machine is a kind of equipment that uses laser technology for cleaning. It uses laser beam to directly act on the surface of the object to be cleaned, and through the absorption and transmission of light energy, dirt and debris are completely removed from the surface. Laser cleaning machine has the characteristics of high efficiency, environmental protection, and non-contact, and has been widely used in various fields. The working principle of laser cleaning machine is based on the absorption and photothermal effect of laser. When the laser beam is irradiated on the surface of the object to be cleaned, the laser energy is absorbed by the dirt on the surface of the object. After absorbing the laser energy, these dirt will undergo thermal expansion, rupture or evaporate. The laser beam can directly peel off the dirt from the surface of the object to be cleaned through the photothermal effect. In this way, the laser cleaning machine can achieve a fast and thorough cleaning effect. The laser cleaning machine can clean different types of dirt by adjusting the laser parameters. For example, for the oxide layer on the metal surface, a high energy density laser beam can be used for cleaning. For some vulnerable materials, the laser parameters can be adjusted to make the energy density of the laser beam lower to avoid damage to the material. The laser cleaning machine can also clean objects of different shapes and sizes by controlling the scanning speed and scanning path of the laser beam.
Laser beams can be reflected and focused by lenses, focusing the laser beam onto a smaller area to achieve efficient cleaning. Laser cleaning machines remove dirt from the surface of the object being cleaned through the absorption of laser energy and the photothermal effect. Its high efficiency and environmental protection make it an indispensable and important equipment in the field of modern cleaning. With the continuous development of laser technology, laser cleaning machines will show a broader application prospect in the future.
