Working principle of fiber laser cleaning machine
In the manufacturing process, contamination is inevitable. For high-precision workpiece manufacturing, the surface of the workpiece is often attached with sub-micron contamination particles, which are often very tightly attached. Traditional cleaning methods cannot be removed, and the surface cleaning of workpieces with nano-laser irradiation is very effective. Since the cleaning of the workpiece by the laser is non-contact, it is very safe to clean the precision workpiece or its delicate parts, and its accuracy can be guaranteed.
Laser cleaning Traditional cleaning industry has a variety of cleaning methods, most of which use chemical agents and mechanical methods for cleaning. How to find a cleaner, non-destructive cleaning method is a problem we have to consider. Laser cleaning has the characteristics of no grinding, non-contact, no thermal effect, and is suitable for objects of various materials, and is considered to be the most reliable and effective solution. At the same time, laser cleaning can solve problems that cannot be solved by traditional cleaning methods.
So, what is laser cleaning? What are the advantages of laser cleaning? Today, the technical editor will introduce the laser cleaning technology to you.
Analysis of the concept and advantages of laser cleaning:
Conceptual Analysis of Laser Cleaning
The laser cleaning process relies on the properties of laser-generated light pulses, based on photophysical reactions induced by the interaction between high-intensity beams, short-pulse lasers, and the contamination layer. The fast and concentrated pulse strikes with extremely high power and evaporates the residue on the surface.
Laser pulses are ideal for removing organic substances, such as dirt left in tire molds; short-term shocks do not heat the metal surface and damage the substrate. Laser cleaning can not only clean organic pollutants, but also inorganic substances, including metal rust, metal particles, dust, etc.
Analysis of the advantages and characteristics of laser cleaning
Laser cleaning is a “green” cleaning method that does not require the use of any chemicals and cleaning fluids. The cleaned garbage is basically solid powder, small in size, easy to store and recycle, and can easily solve the problems caused by chemical cleaning. Environmental pollution. Under the increasingly strict environment of environmental protection regulations in my country, the traditional cleaning industry has various cleaning methods, and most of them use chemical agents and mechanical methods for cleaning.
Laser cleaning can quickly and cleanly clean or remove surface paint; accurate cleaning and stripping results; no damage to substrates; low cost; noise; requires very little maintenance.
The traditional cleaning method is often contact cleaning, which generates mechanical force on the surface of the object to be cleaned, which damages the surface of the object to be cleaned or the cleaning medium adheres to the surface of the object to be cleaned, which cannot be removed, resulting in secondary pollution. Contact makes these problems easy to fix.
The laser can be transmitted through the optical fiber and cooperate with the manipulator and robot, which can easily realize long-distance operation, and can clean the parts that are difficult to reach by traditional methods. This can ensure the safety of personnel when using in some dangerous places; laser cleaning has high efficiency and saves time. .
Laser cleaning can remove various contaminants on the surface of various materials and achieve cleanliness that cannot be achieved by conventional cleaning. In addition, it can selectively clean the contaminants on the surface of the material without damaging the surface of the material; although the initial investment of the laser cleaning system is high, the cleaning system can be used stably for a long time, and the operating cost is low. Electric bill.
Laser cleaning can not only clean organic pollutants, but also inorganic substances, including metal rust, metal particles, dust, etc. The technology for some practical applications is very mature and widely used. Such as: mold cleaning, weapon equipment cleaning, old aircraft paint cleaning, building exterior wall cleaning, electronics industry cleaning, precision deesterification cleaning in precision machinery industry, nuclear power plant reactor pipeline cleaning, etc.
The above is an analysis of the concept and advantages of laser cleaning. Laser cleaning plays an important role in many fields and is used in automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building exterior wall cleaning, cultural relics protection, circuit board cleaning, precision parts processing and manufacturing, liquid crystal display cleaning, Areas such as chewing gum residue removal can play an important role.
