Chapter 1: Overview
1.1 Introduction of fiber laser marking machine
The laser marking machine uses the laser beam to make permanent mark on the surface.
The main effect of laser marking machine is:
1Evaporate the target material surface with laser and show the deep material;
2Cause the physical chemistry reaction to the surface with laser light and "engrave" the
required pattern and text;
3Burn the material with laser, thus show the required pattern and text. The fiber laser
marking machine is mainly composed of: fiber laser, galvanometer (marking head), software control
card, industrial control computer, equipment cabinet, and horizontal stand for work piece, etc.
4Applicable to pipes industry, cables industry, gift industry, electronics industry, packaging
industry, pharmaceutical industry, food and beverage, tobacco and alcohol industry, daily necessities
industry, etc.
1.2 Working principle of fiber laser marking machine
It uses the fiber laser to produce laser and educes the laser with fiber, and then cooperate with
high-speed optical scanning galvanometer for work piece marking. The core component is the fiber
laser.
The fiber laser adopts the rare-earth-doped fiber as the gain medium. The fiber core in the fiber
laser is very thin, so the high power density can be easily formed within the fiber under the action of
pump light, causing the laser-level population inversion of the laser material. Therefore, the
appropriate extra positive feedback circuit can cause the resonant cavity and form the laser
oscillation. In addition, the fiber matrix has wide fluorescence spectra, so the fiber laser is generally
tunable (its wavelength can be adjusted within a certain scope), and mark several colors when
marking (corresponding material).
1.3 The characteristics for fiber laser are as follows:
* BEC-C20 laser marking machine adopts the fiber laser with the service life of 100000h, and the

performance is superior in the world. The beam is high-quality with basic mode output (TEM00),
and the focusing spot diameter is less than 20um. The divergence angle is about 1/4 of the
semiconductor pump. The single line is thinner, so it is more suitable for the fine and precision
marking.
* It has small volume, low power consumption, less than 600W for the complete machine; the
built-in air cooling abandons the heavy water chilling unit, so it covers less area, can be installed
easily, energy-saving and portable.
* Using imported air-cooled laser, the main beam light path is completely enclosed;
* The electro-optic conversion efficiency is high, easy to use without the optical adjustment or
maintenance. The structure is compact with high system integration and less malfunction.
* There is no need for any maintenance, with long service life, can work under bad environment.
* The processing speed is 2-3 times of the traditional marking machine. The optical scanning
galvanometer has good laser repetition frequency without distortion under high speed.
* The fiber laser is equipped with the optical isolator, which can effectively shield the reflected
light, and can be operated in the highlighted high-reflective materials, such as the gold, silver, copper,
aluminum and silicon. The deviation mirror centre is not needed, greatly broadening the application
field. And for different metals, the adjustment of frequency and energy can produce different colors.
* The marking software has powerful function that can be compatible with Coreldraw, AutoCAD
and other software; it supports the PLT, PCX, DXF, BMP, etc., and can directly use SHX, TTF word
stock; it also supports the automatic coding, printing serial number, batch number, date, barcode, QR
code, automatic skipping, etc.; USB interface controls the output.

Chapter 7 Maintenance and preservation
BEC-C20 laser marking machine is mainly composed of electronic devices, precision instruments
and optical devices and it requires a high standard of service environment and daily maintenance.
7.1 Notes for maintenance
* The marking machine and computer should be powered off when the machine doesn’t work.
* The field lens cap should be well capped to prevent the optical lenses from being contaminated
by the dust when the machine doesn’t work.
* The circuit is in a state of high voltage when the machine works, and non-professional personnel
are forbidden to conduct an overhaul at start-up ,which may result in electric shock .
* The power should be immediately cut off if there is any failure of the machine.
* As the devices have been used for a long time, the dust in the air absorbs on the lower-end
surface of the focusing mirror, which may lower the power of the laser and affect the marking effect,
or may even overheat and then crack the optical lenses in serious cases. The surface of the focusing
mirror should be carefully checked whether it is contaminated when the marking has not showed a
good effect.
If the surface of the focusing mirror is contaminated, the lower-end surface of the focusing mirror
should be removed and the cleaned.
Be particularly careful when removing the focusing mirror and take care not to cause any damage to
it. At the same time, do not touch the surface of the focusing mirror by your hands and other objects.
The surface of the focusing mirror should be cleaned as follows: mix ethanol (pure) with ethyl ether
(analytic pure) at a ratio of 3:1, immerse a long fiber cotton or lens tissue into the mixed liquid and
then gently scrub the lower-end surface of the focusing mirror, and the cotton swab or lens tissue
should be changed for the other side.
* Do not move the marking machine when it works, so as not to cause any damage to it.
