Many people are not very familiar with laser marking machines, so they will not be able to tell what industry they are going to use, and it is unclear whether their industries will use them. In fact, laser marking machines are widely used and, in terms of concepts, are useful. Marking can be used to laser marking machine.

The so-called fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has the characteristics of small volume (no water cooling device, use of air cooling), good beam quality (base mode), and maintenance-free characteristics, mainly by the laser. 、Vibration lens、Marking card consists of three parts, laser marking machine using laser fiber laser production, beam quality is good, its output center is 1064nm, the whole life of about 100,000 hours, compared to other types of laser marker life Long, electro-optical conversion efficiency is more than 28%, compared with other types of laser marking machine 2% -10% of the conversion efficiency has a great advantage in energy-saving environmental protection and other aspects of outstanding performance.

Features

1, can be a variety of metal, non-metallic materials processing. In particular, marking high hardness, high melting point, and brittle materials is more advantageous.

2. Non-contact processing, no damage to the product, no tool wear, and good mark quality.

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

4, high processing efficiency, using computer control, easy to implement automation.

Field of application

Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communications products, aerospace devices, various automotive parts, home appliances, hardware tools, molds, wire and cable, food packaging, jewelry, tobacco and military affairs and many other Field graphics and text markings, as well as mass production line operations.

Future advantages

(1) The advantages of low-cost, mature technology and the availability of optical fibers for miniaturization and intensification brought about by glass fiber;

(2) The glass fiber does not require strict phase matching with the incident pump light like a crystal. This is due to the non-uniform broadening caused by the split of the glass substrate Stark resulting in a wider absorption band;

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

(4) Output laser wavelength is high: This is because rare earth ions are very rich in energy levels and their rare earth ion species;

(5) Tunability: Due to the wide range of rare earth ions and the broad spectrum of fluorescence of glass fibers.

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

(7) Optical fiber derivation enables the laser to easily perform a variety of multi-dimensional arbitrary spatial processing applications, making the mechanical system design very simple.

(8) It is capable of working in a harsh environment and has a high degree of tolerance for dust, vibration, impact, humidity, and temperature.

(9) Without thermoelectric cooling and water cooling, simple air cooling is required.

(10) High electro-optic efficiency: The integrated electro-optical efficiency can be as high as 20% or more, which greatly saves power consumption during operation and saves operating costs. The high-power, commercial fiber laser is six kilowatts.

Routine maintenance

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

When the unit is not working, cover the lens of the field lens to prevent dust from contaminating the optical lens.

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

If any malfunction occurs in this unit, the power should be cut off immediately.

When the equipment is used for a long time, the dust in the air will be absorbed on the lower surface of the focusing lens. The light will reduce the power of the laser and affect the marking effect. In severe cases, the optical lens will absorb the temperature and cause burst. When marking is not effective, carefully inspect the surface of the focusing mirror for contamination.

If the surface of the focusing lens is contaminated, remove the focusing lens to clean the lower surface.

Remove the focusing lens with special care, taking care not to damage or fall; at the same time, do not touch the focusing mirror with your hands or other objects.

The cleaning method is to mix absolute ethanol (analytical purity) and (analytical purity) in a ratio of 3:1, infiltrate the mixture with a long fiber swab or lens paper, and gently scrub the bottom surface of the focusing lens. Each side must be cleaned. Replace the cotton swab or lens paper.

During the operation of the marking machine, the marking machine must not be moved to avoid damaging the machine.

Do not cover the heap or other items on the marking machine to avoid affecting the cooling effect of the machine.
