In modern manufacturing and processing industries, the application of marking and engraving technology is becoming more and more common. Among them, laser marking technology has attracted widespread attention due to its advantages of high precision, high efficiency and environmental protection. As one of the important laser marking equipment, CO2 laser marking machine has become an important tool for marking and processing in many industries. This article will introduce the basic concepts, development history and application of CO2 laser marking machine in various fields to help readers fully understand the charm and potential of this technology.
CO2 laser marking machine is a device that uses CO2 laser for marking and engraving. CO2 laser uses CO2 gas as the main medium, and excites gas molecules through electric current to produce high-energy laser beams. The core principle of this type of laser marking machine is to use the high temperature effect of the laser beam to accurately focus the laser on the surface of the material through a focusing lens, so that the material is locally heated, thereby inducing evaporation, melting, carbonization or chemical reaction, and achieving the effect of marking or engraving.
CO2 laser marking machine is widely used in many fields such as identification, personalized customization, and artistic creation on the production line due to its excellent processing capabilities. Common materials include paper, wood, plastic, leather, etc. Its advantages include high precision, fast processing, and no need for additional processing materials, making laser marking an indispensable part of modern production.
CO2 laser marking machines use the laser beam emitted by CO2 lasers to mark and engrave on the surface of materials. The basic working principle includes the generation of lasers, the transmission and focusing of the beam, and the interaction with the material. The following will explain in detail its working mechanism and the basic steps of the marking process.
- Laser generation:
CO2 lasers are mainly composed of laser media (CO2 gas and other gases such as helium and nitrogen). When current passes through the laser tube, the gas molecules are excited to a high energy state, followed by a radiation transition, releasing laser photons.
Laser photons continuously form gain through reflectors in the laser cavity, and finally generate a laser beam.
- Beam transmission:
The generated laser beam is guided and adjusted by optical elements (such as lenses and mirrors) to ensure that the laser energy can be effectively transmitted to the marking target material.
- Focusing:
A specific focusing lens is used to focus the laser beam to a very small point to achieve high concentration. The focused laser beam has an extremely high energy density and can apply sufficient heat to the surface of the target material.
- Material processing:
The focused laser beam irradiates the surface of the material, and the high temperature generated causes partial melting, evaporation or carbonization of the material, thereby forming a mark or engraving effect on the surface of the material.
Through the above steps, the CO2 laser marking machine can achieve high-precision marking and engraving on various materials, providing good identification and decorative effects for the product. With the continuous development of technology, the application scenarios and effects of laser marking will continue to expand.
