Many people don’t know much about laser marking machines, so they don’t know what industries they will be used in, and they don’t know if the machine will be used in their own industries. In fact, laser marking machines are widely used and conceptually useful Laser marking machine can be used when marking.

The so-called fiber laser marking machine means that the marking machine uses laser source. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), and maintenance-free. It is mainly composed of lasers source, Galvo head and Control board. The marking machine adopts fiber laser has beam quality. Its output center is 1064nm. The whole lifetime is about 100,000 hours, which is longer than other types of laser markers.The electro-optical conversion efficiency is more than 28%, which has a great advantage over other types of laser marking machines with a conversion efficiency of 2%-10%. It has outstanding performance in energy saving and environmental protection.

Machine Features

1. It can process a variety of metal and non-metal materials. Especially for high hardness, high melting point, brittle materials, marking is more advantageous.

2. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.

3. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.

4. High processing efficiency, computer control, easy to realize automation.

Application field

Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, 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, and mass production line operations.

Future advantage

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

(2) The glass fiber does not need to have a strict phase matching for the incident pump light as a crystal. This is because the non-uniform broadening caused by the Stark splitting of the glass matrix results in a wider absorption band;

(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) The output laser has many wavelengths: this is because the energy levels of rare earth ions are very rich and there are so many kinds of rare earth ions;

(5) Tunability: Due to the wide energy level of rare earth ions and the wide fluorescence spectrum of glass fiber.

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

(7) The fiber is exported, so that the laser can be easily qualified for various multi-dimensional and arbitrary space processing applications, making the design of the mechanical system very simple.

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

(9) No need for thermoelectric cooling and water cooling, just 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. The high power, commercial fiber laser is six kilowatts.

Daily maintenance

When the machine is not working, the power supply of the marking machine and computer should be cut off.

When the machine is not working, cover the field lens lens to prevent dust from polluting the optical lens.

When the machine is working, the circuit is in a high-voltage state. Non-professionals should not overhaul it when it is turned on to avoid electric shock.

Any failure of this machine should immediately cut off the power supply.

When the equipment is used for a long time, dust in the air will be adsorbed on the lower end surface of the focusing lens. The lighter ones will reduce the power of the laser and affect the marking effect; the more serious ones will cause the optical lens to overheat and cause it to burst. When the marking effect is not good, check carefully whether the surface of the focusing lens is contaminated.

If the surface of the focusing lens is contaminated, remove the focusing lens and clean its lower end surface.

Take special care when removing the focusing lens, and be careful not to damage or fall; at the same time, do not touch the surface of the focusing lens with your hands or other objects.

The cleaning method is to mix absolute ethanol (analytical grade) and (analytical grade) in a ratio of 3:1, use long-fiber cotton swabs or lens paper to intrude into the mixture, gently scrub the lower end surface of the focusing lens, Replace the cotton swab or lens paper once.

During the working process of the marking machine, the marking machine shall not be moved to avoid damage to the machine.

Do not cover or place other items on the marking machine, so as not to affect the heat dissipation effect of the machine.
