● Product features

The characteristics of the optical fiber laser marking machine produced by Shenzhen Laser Technology Co., Ltd. have many unique advantages in the application of laser marking. Unlike traditional solid lasers, using crystal rods as laser medium, the laser medium of fiber lasers is very long ytterbium doped double clad fiber and pumped by high-power multimode laser diodes.

1.Excellent beam quality, suitable for precision and precision marking

The beam quality of fiber laser marking machine is much better than that of traditional flash pump and diode pumped solid laser marking machine. It is output for fundamental mode (TEM00) and divergence angle is 1/4 of diode pumped laser. It is especially suitable for high precision and fine marking.

2. compact, convenient handling and portable

The weight and floor area of the optical fiber laser marking machine are 1/10 and 1/4 of the flash lamp pumped solid laser marking machine, which can save space and facilitate the handling. It can adapt to the requirement of frequent change of the processing place, and realize the portability of the product.

3.Laser output power is stable and the reliability of equipment is high

The weight and floor area of the optical fiber laser marking machine are 1/10 and 1/4 of the flash lamp pumped solid laser marking machine, which can save space and facilitate the handling. It can adapt to the requirement of frequent change of the processing place, and realize the portability of the product. The energy fluctuation is less than 2%, which ensures the stable quality of laser marking. The average time of no fault can reach more than 100 thousand hours, which is 200 times and 15 times of flashlamp pump and semi-solid laser marking machine respectively.

4.High efficiency, low energy consumption and cost saving

The electro-optical conversion efficiency is 30%, the device power is only 200~500W, and the daily power consumption is 10 degrees. It is 1/10 of the flash lamp pumped solid-state laser marking machine. The long-term usage can save a lot of energy consumption for the users.

5.The operating software of independent intellectual property rights is easy to operate and powerful

It can mark vector graphics, text, barcode, two-dimensional code and so on. It can be upgraded to online marking, automatic marking date, flight number, batch number and serial number, supporting PLT, PCX, DXF, BMP and other file formats, and directly using SHX and TTF font library.

● System composition of laser marking machine

The YLP-10/20/50 fiber laser marking machine mainly consists of four parts: fiber laser, optical and galvanometer scanning system, computer control system and worktable.

1、Fiber laser

The integrated structure of the fiber laser has no optical pollution and no power coupling loss. The structure is compact and compact, and the air cooling has the high efficiency and reliability that other lasers do not possess.

Excellent beam quality

Because the laser medium of the fiber laser is ytterbium doped double clad fiber, the length of the resonator is long, so the beam quality is very good. The M2 value is 1.2, and the output spot diameter can reach 20 microns. The excellent beam quality ensures that the fiber laser marking machine achieves satisfactory marking effect on various materials, including metal, ceramic, PCB circuit board, coated plastic and glass, etc.

Small size, suitable for bad environment

Because of the excellent flexible winding of the fiber, the laser is designed to be rather small, flexible, compact and small in size. The optical fiber has high surface area / volume ratio, good heat dissipation effect, no need for large water cooling system, simple air cooling, and can work in harsh environment, such as high impact, high vibration, high temperature and dusty condition.

Maintenance free operation

Fiber lasers do not require any maintenance, and of course not include adjusting or cleaning lenses.

2、Optical and vibrating mirror scanning system

Optical system: 1064nm high precision reflection and spotlight system based on vibrating mirror.

Beam expander: a beam of 3 times a beam before the beam is reflected.

Laser correction: choose the He-Ne laser collimating system of 0.6328um to indicate the position of optical axis, indicating that the light is coaxial with the laser. When machining, it can achieve track tracing function and carry out precise counterpoint in time.

Galvanometer is the actuator that makes the laser run according to a predetermined trajectory. It is mainly composed of high precision servo motor, motor drive plate, reflector, F- theta lens and DC power supply.

3、computer control system

Computer configuration P4 or equivalent level processor, anti-jamming computer motherboard, Chinese WindowsXP operating system.

The marking software based on the windows interface has the following:

Graphical operating interface

• CAD graphics that can be invoked in a variety of formats

• a variety of Chinese and English fonts

Direct serial number and bar code editing

• comprehensive laser parameter database

Easy stop control function

• help function
