Application of fiber laser marking machine in steel building materials industry

Fiber laser marking machine is the most advanced laser marking equipment in the world today. It has the characteristics of good beam quality, small size, fast speed, long working life, flexible and convenient installation and maintenance-free. Widely used in integrated circuit chips, computer accessories, industrial bearings, clocks, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs, etc. Field graphics and text marking, as well as high-volume production line jobs. The core main component of fiber laser marking machine is fiber laser, which is divided into continuous fiber laser and pulsed fiber laser. According to the power size: continuous 5W, 10W, 20W to 400W, 1000W or more; pulse 10W, 15W, 20W, 25W, 30W to 50W.

Most modern cities are made of steel building materials. Steel building materials have become an indispensable part of our lives. The appearance is more beautiful, and some models and pattern numbers will be marked on it. For its hard materials, the absorption capacity of various light is different, and it is a practical and wise choice to use a fiber laser marking machine to mark it.

As for why the fiber laser marking machine is selected, the reason is that the laser light emitted by the laser can be well absorbed by the steel building materials to form graphic text, which is produced by Wuhan Harmony. The fiber laser marking machine adopts domestic well-known brand lasers, which are certified in quality. They are also equipped with high-speed galvanometer scanning system and professional laser marking machine software, which have more advantages in marking speed and convenient operation.

Because the whole machine adopts modular design and integrated air-cooling setting, the photoelectric conversion efficiency is higher, the beam quality is good, and the lines are more fine. The effect of marking is naturally more excellent, and it is a good choice for marking on metal materials such as steel building materials.

As the representative of the third-generation laser technology, fiber lasers have the following advantages:

(1) The advantages of miniaturization and intensification brought by the low manufacturing cost of glass optical fiber, mature technology and the flexibility of optical fiber;

(2) The glass fiber does not require strict phase matching for the incident pump light like the crystal, which is due to the wide absorption band caused by the non-uniform broadening caused by the Stark splitting of the glass matrix;

(3) The glass material has a very low volume-to-area ratio, fast heat dissipation and low loss, so the up-conversion efficiency is high and the laser threshold is low;

(4) Output Many laser wavelengths: This is because the energy levels of rare earth ions are very rich and there are many types of rare earth ions;

(5) Tunability: due to the wide energy levels of rare earth ions and glass The fluorescence spectrum of optical fiber is broad.

(6) Since there is no optical lens in the resonant cavity of the fiber laser, it has the advantages of adjustment-free, maintenance-free and high stability, which is unmatched by traditional lasers.

(7) The fiber export makes the laser easily competent for various multi-dimensional arbitrary space processing applications, making the design of the mechanical system very simple.

(8) Competent in harsh working environment, with high tolerance to dust, shock, shock, humidity and temperature.

(9) No need for thermoelectric cooling and water cooling, just simple air cooling.

(10) High electro-optical efficiency: The comprehensive electro-optical efficiency is as high as 20% or more, which greatly saves power consumption during work and saves operating costs.

(11) High power, the current commercial fiber laser is six kilowatts.
