Laser marking machines are currently divided according to laser sources into gas laser sources and solid laser sources. The representative model of the gas laser source is a carbon dioxide laser marking machine, and the representative model of the solid-state laser source is a fiber laser marking machine, and a small part uses purple light and green light.
Fiber laser marking machine
It is mainly composed of three parts: laser, vibrating lens and marking card. The marking machine adopts fiber laser to produce laser. The quality of the beam is good. Its output center is 1064nm and the life of the whole machine is about 100,000 hours. Compared with other types of laser marking The device has a longer life and the electro-optical conversion efficiency is more than 28%. Compared with other types of laser marking machines, the conversion efficiency is 2% -10%. It has great advantages in energy saving and environmental protection.
CO2 laser marking machine
The CO2 laser is a gas laser with a far-infrared light frequency band of 10.64um. The CO2 gas is used to fill the discharge tube as the medium for generating the laser. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube to release the gas molecules After the laser is emitted, the laser energy is amplified to form a laser beam for processing the material.
UV laser marking machine
The ultraviolet laser marking machine is equipped with a deep ultraviolet laser, imported high-speed scanning galvanometer system, etc .; because the ultraviolet laser marking machine has a very small focusing spot and the processing heat affected area is minimal, the ultraviolet laser marking machine can perform ultra-fine marking and special Material marking, UV laser marking machine is the first choice for customers who have higher requirements for marking effect. The ultraviolet laser marking machine has the characteristics of high electro-optical conversion rate, long service life of nonlinear crystal, stable operation of the whole machine, high positioning accuracy, high operating efficiency, and modular design for easy installation and maintenance. In addition, it can be equipped with a two-dimensional automatic working table, which can realize multi-station continuous marking or large-format marking.
