1. The advantages of low manufacturing cost, mature technology, and the flexibility of glass fiber optics in terms of miniaturization and intensification;
2. Glass fiber does not require strict phase matching for incident pump light like crystals, due to the non-uniform broadening caused by Stark splitting of the glass matrix, resulting in a wider absorption band;
3. Glass materials have an extremely low volume to area ratio, fast heat dissipation, and low losses, resulting in high upconversion efficiency and low laser threshold;
4. Multiple output laser wavelengths: This is because rare earth ions have very rich energy levels and a wide variety of rare earth ion types;
5. Tunability: Due to the wide energy levels of rare earth ions and the broad fluorescence spectrum of glass fibers.
Due to the absence of optical lenses in the resonant cavity of fiber lasers, they have the advantages of no adjustment, no maintenance, and high stability, which traditional lasers cannot match.
7. Fiber optic export enables lasers to easily handle various multidimensional and arbitrary spatial processing applications, making the design of mechanical systems very simple.
8. Capable of working in harsh environments, with high tolerance for dust, vibration, shock, humidity, and temperature.
9. No need for thermoelectric cooling or water cooling, only simple air cooling is required.
10. High electro-optical efficiency: With a comprehensive electro-optical efficiency of over 20%, it significantly reduces power consumption during operation and saves operating costs. The high-power, commercially available fiber laser is 6000 watts.
Advantage Analysis
Laser marking machine technology, as a modern precision machining method, has the following advantages compared to traditional machining methods such as corrosion, electrical discharge machining, mechanical engraving, and printing:
1. Using laser as a processing method, there is no processing force between the workpiece, which has the advantages of non-contact, no cutting force, and low thermal impact, ensuring the original accuracy of the workpiece. At the same time, it has a wide adaptability to materials and can produce very fine markings on the surfaces of various materials with excellent durability;
2. Laser has good spatial and temporal control, and has a large degree of freedom in the material, shape, size, and processing environment of the processed object, making it particularly suitable for automated processing and special surface processing. And the processing method is flexible, which can meet the needs of laboratory style single item design and industrial large-scale production;
3. Laser engraving is fine, and the lines can reach the millimeter to micrometer level. It is very difficult to imitate and modify the markings made by laser marking technology, which is extremely important for product anti-counterfeiting;
4. The combination of laser processing system and computer numerical control technology can form efficient automated processing equipment, which can print various texts, symbols, and patterns. It is easy to use software to design and mark patterns, change marking content, and adapt to the requirements of modern production efficiency and fast pace;
5. Laser processing has no pollution sources and is a clean, pollution-free, and highly environmentally friendly processing technology;
one
When the machine is not working, the marking machine and computer power should be cut off.
two
When the machine is not working, cover the field lens to prevent dust from contaminating the optical lens.
three
The circuit of this machine is in a high voltage state during operation. Non professionals should not perform maintenance during startup to avoid electric shock accidents.
four
If any malfunction occurs on this machine, the power should be cut off immediately.
five
Long term use of the equipment will cause dust in the air to adhere to the lower surface of the focusing lens, which can reduce the power of the laser and affect the marking effect; Severe cases can cause the optical lens to absorb excessive heat and explode. When the marking effect is poor, the surface of the focusing lens should be carefully checked for contamination.
six
If the surface of the focusing lens is contaminated, the focusing lens should be removed and its lower surface cleaned.
seven
Be particularly careful when removing the focusing lens, and be careful not to damage or fall it; At the same time, do not touch the mirror surface of the focusing lens with your hands or other objects.
eight
The cleaning method is to mix anhydrous ethanol (analytical grade) with ether (analytical grade) in a ratio of 3:1, and use a long fiber cotton swab or lens paper to infiltrate the mixture. Gently wipe the surface of the lower end of the focusing lens, and replace the cotton swab or lens paper every time it is wiped.
nine
During the operation of the marking machine, do not move it to avoid damaging the machine.
ten
Do not cover the stack or place other items on the marking machine to avoid affecting the heat dissipation effect of the machine.
