Laser Source
The laser source generates the high-intensity laser beam used for cleaning surfaces. Common types of lasers used in laser cleaning machines include fiber lasers, pulsed lasers, and continuous-wave lasers. The choice of laser source depends on factors such as the type of material being cleaned, the desired cleaning efficiency, and the specific application requirements.

Scanning System
The scanning system directs and controls the movement of the laser beam across the surface to be cleaned. It typically consists of galvanometer mirrors or mirrors mounted on high-speed motors, which deflect the laser beam in a controlled manner to scan the entire surface area. The scanning system allows for precise and uniform cleaning of the target surface.

Optical System
The optical system includes lenses, mirrors, and beam delivery optics that focus and deliver the laser beam to the surface being cleaned. The optical components help shape and control the laser beam's size, intensity, and focus spot size to optimize cleaning performance and efficiency.

Control System
The control system regulates and coordinates the operation of the laser cleaning machine, including laser power, scanning speed, beam trajectory, and other parameters. It may consist of software, controllers, and user interface components that allow operators to set and adjust cleaning parameters according to specific requirements.

Safety Features
Laser cleaning machines are equipped with safety features to protect operators and ensure safe operation. These may include interlocks, safety curtains, laser safety glasses, and warning lights to prevent accidental exposure to laser radiation and maintain a safe working environment.

Cooling System
The laser source and other components of the laser cleaning machine generate heat during operation, so a cooling system is required to dissipate heat and maintain optimal operating temperatures. The cooling system may use air or water cooling techniques to prevent overheating and ensure long-term reliability of the machine.

Fume Extraction System
Laser cleaning can produce vaporized contaminants and debris, so a fume extraction system is often integrated into the machine to remove airborne particles and gases generated during the cleaning process. The fume extraction system helps maintain air quality and prevent the accumulation of hazardous fumes in the workspace.

Motion Control System
Laser cleaning machines may include a motion control system for positioning and moving the workpiece relative to the laser beam. This allows for automated or semi-automated cleaning of large or complex surfaces, such as automotive components, aerospace parts, and machinery.

Types of Laser Cleaning Machine

Handheld Laser Cleaning Machines
Handheld laser cleaners, also called workstations on wheels, are easy to move from one location to another.

Fiber Laser Cleaning Machines
The laser technology removes dirt and impurities on various materials, such as ceramics and metals. It uses focused laser energy to vaporize contaminants like paint, rust, and oil, which is ideal for industrial cleaning. The fiber laser cleaning system is low maintenance and can remove unwanted materials without damaging the surface texture.

Manually Loaded Cleaning Machines
Unlike handheld laser cleaning machines, these devices are 100% safe for operators. You load parts into the device before triggering the cleaning process. Depending on their chosen tool, users might perform other tasks, such as managing fixtures and opening the door. Manual workstations often come with a rotary table, helping you to meet the high throughput requirements. You can install it offline or directly into the production line.

You install these devices directly on conveyors for surface texturing and automating impurities removal before operations. It offers advanced features to manage inconsistencies when processing large parts in areas that need cleaning. Conveyor laser cleaning system is handy in the automotive industry, where manufacturers move different parts during production.

How to Choose Laser Cleaning Machine

Power and Wavelength
The power and wavelength of the laser are crucial factors to consider when selecting a laser cleaning machine. Higher-powered lasers can remove thicker layers of contaminants, while lower-powered lasers are suitable for delicate surfaces. The appropriate wavelength depends on the type of material and contaminant being removed. Consult with the manufacturer to determine the best specifications for your specific application.

Working Area
The working area of the machine refers to the size of the surface that can be cleaned in a single pass. Choose a machine with a larger working area if you need to clean larger surfaces or if you require faster cleaning times.

Portability and Ease of Use
Laser Cleaning Machine offer the advantage of portability, making them suitable for field applications. Consider the weight and ergonomic design of the machine to ensure operator comfort and efficiency.

How to Maintain Laser Cleaning Machine

Optics Maintenance
Irregularly inspect lenses and mirrors for dirt, smudges, or damage. Use a clean, lint-free cloth or soft brush to remove debris. If there is stubborn dirt or residue, please use the appropriate cleaning solution recommended by the manufacturer. Apply the solution to a clean, lint-free cloth and gently wipe the optics, being careful not to scratch or damage them.

Laser Alignment
Follow the manufacturer’s instructions for a laser alignment check. This may involve the use of alignment targets, specialized tools, or software provided by the manufacturer. If misalignment is detected, consult the user manual or contact the manufacturer for specific alignment procedures. Adjust the laser generator according to the recommended guidelines to ensure proper alignment.

Cooling System Maintenance
Check cooling fans or radiators regularly to make sure they are clean and free of dust, debris, or blockages.Remove any dust, debris, or obstructions that may limit cooling efficiency. It is recommended to use compressed air or a soft brush to clean the heat sinks and fans.

Lubrication
Check the owner’s manual for any moving parts that need to be lubricated, such as gears, bearings, or sliders. Use the lubricant specified by the manufacturer and apply in recommended amounts and intervals. Apply lubricant to designated parts according to the manufacturer’s instructions, ensuring even distribution and avoiding over-lubrication, which can attract dirt or impede movement.

Consumables Replacement
Monitor the condition of consumable parts such as filters, protective windows, or laser cleaning nozzles. Refer to the manufacturer’s guidelines for the expected useful life of these consumables and replace them accordingly. Replace filters when clogged or damaged to maintain proper airflow and particle filtration.

Working Principle of Laser Cleaning Machine

01

High Temperature Vaporization

The highly concentrated laser beam can generate very high heat energy around the spot, so dirt can be quickly vaporized or peeled off instantly;

02

Swell and Fall Off

The scattering of the laser beam is small and the direction is stable. We can adjust the energy density of the laser by controlling the laser beam spot with different diameters, so that the dirt is heated and then changed. When the expansion force of dirt is greater than the adsorption force of dirt to the substrate, detachment and falling will occur.

03

Shock Off

The laser cleaning beam can produce a high-frequency ultrasonic wave on the solid surface, thereby causing mechanical resonance to quickly break and fall off the dirt.
