What Is Laser Cleaning Machine Working Principle
The principle of laser rust removal is to use the characteristics of high energy density, controllable direction, and strong convergence ability of the laser beam to destroy the bonding force between rust and the substrate, or to directly vaporize pollutants for rust removal.
Specifically, the beam emitted by the laser is absorbed by the pollution layer on the surface to be treated. The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), producing shock waves. Shock waves cause pollutants to break into fragments and be removed. The width of the light pulse must be short enough to avoid heat accumulation that can damage the treated surface. Experiments have shown that when there are oxides on the metal surface, plasma is generated on the metal surface.
Laser Cleaning Machine Main Components
There are currently three main types of laser rust removal cleaning equipment.
- Machine tool fixed equipment, using assembly line operation. Features: The machine is relatively large, with high power and efficiency.
- Handheld fiber laser cleaning machine. Features: Weighing around 150 kilograms, flexible operation of longer fiber optic cables, high cost-effectiveness, low rust removal cost, widely used.
- Small backpack style. Features: Portable, flexible in application, weighing 10-20 kilograms, high in price, and low in cost-effectiveness.
Although their external performance varies, their basic mechanisms can be divided into several systems: laser system, cold water system, control system, output system, and auxiliary system. For the most widely used handheld fiber laser rust removal machine, the main components are divided into laser, chiller, output head, and control system. They can be independently matched just like the CPU, memory module, and display of a desktop computer. A laser is like a computer CPU, a chiller is like a computer fan for cooling, an output head is like a display, and a control system is like a computer system.
Control System of Laser Rust Removal Machine
The core of laser rust removal and cleaning machine is still the control system, and the quality of the control system determines the performance and intelligence level of the machine. The main functions of the control system include:
- Control the operation of various laser cleaning systems.
- Monitor various parameters such as water temperature, laser temperature, humidity, vibration, power on, etc., with a complete alarm system and protective devices.
- Adjust output parameters such as power, scanning speed, scanning width, real-time display, and data recording. Advanced controllers also have remote communication capabilities.
Auxiliary Systems Of Laser Cleaning Machine
In addition, the laser rust removal machine also has some auxiliary systems.
- The alarm system, regardless of any abnormalities in the machine, will first stop operation, then issue an alarm, and only resume operation after solving the problem. Whether the temperature is too high or a component is damaged, it will issue an alarm, and it also has functions such as water interruption, short point, overcurrent, overheating, and leakage protection.
- Recycling system. When a laser rust removal machine is operating, it generally does not need to be processed. When multiple laser rust removal machines are operating simultaneously, especially when removing paint or working in enclosed spaces, a dust recovery system is required. A device similar to a vacuum cleaner can be used to handle the cleaned dust.
- Mobile system. During the operation of a laser rust removal machine, it is often accompanied by the movement of the machine. Generally speaking, the laser rust removal machine has a fiber optic cable of 2-20 meters, but different mobile systems will be used according to different usage scenarios. Mobile systems are mainly divided into handheld mobile, robotic arm control, or 3D displacement platforms. The handheld head is characterized by easy operation but poor uniformity, high requirements for operators, and attention to personnel safety. The robotic arm fixes the laser head on the robotic arm and uses it to clean and remove rust. It has high stability in operation, uniform scanning, but poor flexibility, and many blind spots cannot be cleaned. In actual homework, a combination of robotic arms and handheld devices is mainly used. The three-dimensional displacement platform can achieve x-y-z three-axis cleaning by fixing the cleaning head, which is suitable for regular surface cleaning with high efficiency. At the same time, it can also be cleaned by using the method of laser beam not moving butmoving the object to be cleaned.
Additional Configurations Of Laser Cleaning Machine
In addition to these systems, there are additional devices.
- Liquid spraying device, mainly used in wet cleaning equipment, sprays a certain amount of liquid on the object to be cleaned according to actual needs. Wet laser cleaning has unique uses, such as in paint removal, the efficiency of wet cleaning is 2-3 times that of dry cleaning.
- Monitoring device, real-time monitoring effect, whether it meets expectations, monitoring device is divided into two types: observation window and signal detection device. The observation window roughly observes the effect, and the signal detection is relatively fine, including vibration signals, spectral signals, and acoustic signal lights.
Laser Rust Removal Machine VS. Traditional Rust Removal Machine
Laser Rust Removal Machine Advantages
Compared with traditional rust removal methods, such as sheet metal deburring machine, laser rust removal machines have multiple significant advantages.
- Efficiency: Laser rust removal machines stand out with their high-speed rust removal ability. The laser beam can concentrate high energy on the metal surface in a very short time, causing the rust layer to quickly vaporize or peel off, greatly improving the rust removal efficiency. In contrast, traditional rust removal methods such as manual rust removal and sandblasting rust removal not only take longer, but also may have uneven rust removal effects, which can easily leave residual rust marks.
- Accuracy: The laser rust removal machine adopts a high-precision laser beam, which can accurately irradiate the rusted area and remove the rust layer without causing damage to the object itself. This non-contact rust removal method can maintain the smoothness of the metal surface and avoid surface scratches or damage that traditional rust removal methods may bring.
- Green and environmentally friendly: The laser rust removal machine does not require the use of any chemical agents or cleaning liquids during the rust removal process, and does not produce pollutants such as wastewater and exhaust gas, meeting environmental requirements. In addition, rust removal waste is mainly composed of solid powder, which is small in size, easy to store, and recyclable, further reducing environmental pollution.
- High safety: The laser rust removal machine does not produce noise and vibration during operation, reducing the impact on the operator. Meanwhile, due to its non-contact rust removal method, it reduces the potential safety hazards in traditional rust removal methods, such as sparks and splashes.
- Multi-functionality: In addition to the rust removal function, the laser rust removal machine can also perform various operations such as cleaning and marking, meeting different process requirements. This versatility makes laser rust removal machines more widely applicable in the field of metal processing.
- High degree of automation: The laser rust removal machine can be paired with robots to achieve long-distance operation, which can clean complex workpiece parts and reduce the accident rate of cleaning operations in some dangerous scenarios. This highly automated operating method not only improves work efficiency, but also reduces manual labor intensity.
- Low consumables consumption and low maintenance costs: Although the light source of the laser rust removal machine consumes quickly, compared with other traditional rust removal methods, its overall consumables consumption is lower. At the same time, the maintenance cost of laser rust removal machine is relatively low, which reduces the usage cost.
Fiber Laser Cleaning Machine Disadvantages
Although laser rust removal machines have many advantages, there are still the following shortcomings in practice.
- High price: Compared to traditional mechanical rust removal equipment, laser rust removal machines are more expensive and require significant investment.
