Application scope and industry of laser cleaning

Laser cleaning is divided into automatic laser cleaning equipment and handheld laser cleaning equipment. Automatic laser cleaning equipment is generally combined with conveyor belts, robotic arms, sorting trays, and other devices to form a fully automatic cleaning assembly line; Handheld laser cleaning equipment is mobile and portable. Operators can adjust the direction and angle of laser irradiation by holding the laser head and manually perform cleaning operations.

Based on the light absorption characteristics of materials, laser cleaning can clean most pollutants, including but not limited to the following:

Rust: Rust is one of the most common stains in sheet metal parts. Scattered rusted sheet metal parts require time-consuming and labor-intensive cleaning methods to remove rust. In this case, handheld laser cleaning equipment is used to manually clean the rusted parts, which is both convenient and fast.

Oil stains: Oil stains are the most common stains in molds or mechanical components. After processing, the mold temperature is very high. Traditional cleaning methods require waiting for the removed mold to cool down for several hours before starting to clean. Handheld laser cleaning does not require waiting, and can be carried out immediately on high-temperature molds, saving waiting time.

Dust: Open factory buildings and outdoor machinery are prone to accumulating dust, often mixed with oil stains, making it difficult to clean the foundation. Handheld laser cleaning equipment can easily remove dust, and the collection of scattered dust through gas collection devices can minimize the impact on the health of operators.

Moss: Moss that is difficult to remove often adheres to wooden and stone artifacts. To avoid damage to the artifacts, laser cleaning can be used. By adjusting the pulse width, power, pulse frequency and other parameters of the laser through the controller, the laser can accurately remove stains without harming the cultural relics themselves.

Paint: The outer paint of ships and aircraft often needs to be cleaned and replaced. Traditional cleaning methods can easily cause damage to metal surfaces and pose safety hazards to flight and navigation. For example, using multiple laser cleaning systems can achieve safer and faster cleaning of metal outer paint without damaging the metal substrate, thereby improving safety.

Laser cleaning was initially used for high-end scenarios such as cleaning ancient artifacts and rust removal of precision components. Later, with technological advancements, more advantages of laser cleaning were discovered and gradually expanded to other industries. At present, laser cleaning has a very wide range of applications in many industries such as ships, aerospace, sheet metal, molds, advertising, electronics, etc.
