What Is Fiber Laser Marking Machine?

Fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, using air cooling), good beam quality (fundamental mode), and maintenance-free. It is mainly composed of lasers, Composed of three parts, vibrating lens and marking card, the marking machine uses fiber laser to produce laser, the beam quality is good, its output center is 1064nm, and the life of the whole machine is about 100,000 hours, which is longer than other types of laser marking machines , The electro-optical conversion efficiency is above 28%, which is a great advantage compared to other types of laser marking machines with a conversion efficiency of 2%-10%, and has outstanding performance in energy saving and environmental protection.

Features

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

• It belongs to non-contact processing, no damage to products, no tool wear, and good marking quality.

• The laser beam is thin, the consumption of processing materials is small, and the processing heat-affected zone is small.

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

What Is The Application Of Fiber Laser Engraver?

Widely used in integrated circuit chips, computer accessories, industrial bearings, clocks and 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. Marking of graphics and text in the field, as well as mass production line operations.

What Is The Advantage Of Fibre Laser marking machine?

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

(2) The glass fiber does not need the strict phase matching of 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 an extremely 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 many types of rare earth ions;

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

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

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

(8) Competent for harsh working environments, with high tolerance to dust, vibration, impact, humidity and temperature.

(9) It does not need thermoelectric refrigeration and water cooling, but only simple air cooling.

(10) High electro-optic efficiency: the comprehensive electro-optic efficiency is as high as more than 20%, which greatly saves power consumption during work and saves operating costs. High power, commercially available fiber lasers are six kilowatts.

What is the maintenance of fiber laser?

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

When the machine is not working, cover the lens cover of the field 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 accidents.

If there is any failure of the machine, the power supply should be cut off immediately.

If the equipment is used for a long time, the dust in the air will be adsorbed on the surface of the lower end of the focusing lens. If it is light, it will reduce the power of the laser and affect the marking effect; if it is serious, it will cause the optical lens to overheat and burst. When the marking effect is not good, you should carefully check whether the surface of the focusing mirror is polluted.

If the surface of the focusing lens is polluted, the focusing lens should be removed to clean its lower surface.

Special care should be taken when removing the focusing lens, and be careful not to damage or drop it; at the same time, do not touch the focusing lens surface with hands or other objects.

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

During the working process of the marking machine, do not move the marking machine to avoid damage to the machine.

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