Laser marking machine (lasermarkingmachine) is a laser marking on the surface of a variety of different substances. The effect of marking is to expose the deep matter through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and characters. Laser marking machines are mainly divided into: CO2 laser marking machines , semiconductor laser marking machines , fiber laser marking machines And YAG laser marking machine . At present, laser marking machine is mainly used in some occasions that require more fine and higher precision. Used in electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic keys, building materials, PVC pipes. The following describes the details of several laser marking machines :
Fiber laser marking machine
The principle of fiber laser marking machine : The fiber laser marking machine uses the laser beam to mark the OFweek laser net permanently on the surface of various materials. The effect of marking is to expose deep substances through evaporation of surface substances, or to "etch" traces through the chemical and physical changes of surface substances caused by light energy, or to burn away some substances by light energy, showing the required etching. Various graphics such as patterns, text, and bar codes. The so-called fiber laser marking machine refers to the use of fiber lasers in the marking machine. The fiber laser has the characteristics of small size (no water-cooled device, air-cooled), good quality (primary mode), and maintenance-free. Fiber laser marking machine is mainly composed of fiber laser marking machine , high-speed scanning galvanometer, marking software, industrial computer and cabinet. The fiber laser is the main core component.
Advantages of fiber laser marking machine : Fiber laser marking machine is the most advanced laser marking equipment in the world. It has the characteristics of good beam quality, small size, fast speed, long working life, flexible and convenient installation, and maintenance-free. Widely used in integrated circuit chips, computer accessories, industrial bearings, watches and clocks, electronics and communications products, aerospace devices, various automotive parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs, etc. Field graphics and text marking, and high-volume production line operations.
CO2 laser marking machine Principle: CO2 laser marking machine is a carbon dioxide laser marking machine (CO2 is carbon dioxide). It is a laser galvanometer marking machine using CO2 gas as the working medium. The CO2 laser marking machine is a CO2 laser using CO2 gas as a medium, charging CO2 and other auxiliary gases into a discharge tube, and applying high voltage to the electrode. A glow discharge is generated in the discharge tube, and the gas releases a laser with a wavelength of 10.64um. After the energy is amplified, after scanning by the galvanometer and focusing by the F-Theta mirror, under the control of the computer and the laser marking control card, the image, text, numbers, and lines can be marked on the workpiece according to the user's requirements.
CO2 laser marking machine consists of: CO2 laser marking machine mainly consists of CO2 laser, 10.64 field lens, 10.64 beam expander, CO2 laser power, scanning galvanometer, control computer, laser control card, laser control software, laser machine frame, Laser circulating water system, circuit control system and other components. CO2 laser marking machine main features: using carbon dioxide laser, is a general-purpose model, back focus method, small size, high degree of integration. This machine is suitable for marking most non-metal materials, such as CO2 laser marking machine paper packaging, plastic products, label paper, leather cloth, glass ceramics, resin plastic, bamboo and wood products, PCB boards, etc. The CO2 laser is a gas laser with a wavelength of 10.64um in the far-infrared light band. CO2 gas is used to charge the discharge tube as a medium for generating laser light. When a high voltage is applied to the electrode and a glow discharge is generated in the discharge tube, gas molecules can be released. After the laser is emitted, the laser energy is amplified to form a laser beam for material processing. Semiconductor laser marking machine Principle of semiconductor laser marking machine : semiconductor laser pumped all solid-state laser (DPSSL) laser marking working principle is to use high-power semiconductor quantum well laser instead of gas lamp to pump solid-state crystal for gain medium laser resonance Cavity, so that it can generate lasers with new wavelengths, and lasers with wavelengths such as SHG and THG should be generated using crystal preparation and frequency mixing. Through the design, the entire laser marking process, operating procedures and quality standards have been established from re-inspection of materials, production of parts, process inspection, final assembly and commissioning to final inspection of finished products.
Semiconductor laser marking machine is composed of four systems: optical path system, circuit system, water path system and control system. The optical path system is mainly composed of red light, full reflection, half reflection, module, Q, field lens, beam expander, and scanning. The circuit system is mainly composed of a control circuit (control box), laser power, Q power, and scanning power. The control of OFweek laser network system is mainly composed of scanning galvanometer, computer, control software (board). The waterway system is mainly composed of a water tank and a water pipe, forming a circulating waterway.
Semiconductor laser marking machine advantages: good laser beam mode, high electro-optical conversion efficiency, low power consumption, and maintenance-free; some optoelectronic measurement manufacturers change the light source of the laser in the measurement equipment from the original He-Ne laser to a diode laser to Get the best machine life (He-Ne laser life is generally 10 ^ 4HR, while diode laser life is 10 ^ 5HR, ten times the difference), especially suitable for long-term operation in the field; the switch can be reached instantly, suitable for communication use. In addition, the semiconductor laser marking machine is stable immediately after it is turned on, and it is very suitable to modulate its output with a circuit. For example, the pulse wave modulation method can be used to measure the distance. In the future, this point is absolutely incomparable with semiconductor laser marking machines ); using group III / V in the periodic table, compounds such as gallium arsenide can be used to make diode lasers. When the current passes through the pn interface, It emits various visible lasers and invisible lasers. As long as the semiconductor laser changes the proportion of the combined elements, different energy intervals can be changed. Different energy intervals provide different output wavelengths. Due to the infrared and red wavelengths, it is easy to cooperate with various sensors in communication and measurement. It has a wide range of uses; simple and convenient operation, high marking accuracy; mechanical properties: compact, sturdy, and small.
YAG laser marking machine Among the YAG laser marking machine series, the semiconductor laser marking machine has the highest cost-effective high-end product. With the reduction of manufacturing costs in recent years, it has replaced the lamp pump laser marking machine as the preferred model for laser processing users. The use of semiconductor laser marking machines can greatly save power and consumable costs in subsequent maintenance. , Get better laser marking effect, and can improve equipment reliability and greatly reduce maintenance.
YAG laser marking machine advantages:

Electricity is calculated for one yuan. For one hour of operation, a semiconductor laser marking machine can save 4 yuan in electricity costs per hour compared to a lamp pumped laser marking machine .

The semiconductor laser marking machine is maintenance-free, which greatly increases the stability and reliability of the equipment and reduces the workload of routine maintenance.
5. Other inaccurate savings: The lamp-pumped laser marking machine is bulky and operating noise is large, and the large cold water will generate more heat, especially in the summer in the south, where the ambient temperature is high, and these excess heat will cause Workers' working environment is worse, or more air-conditioning systems are needed to regulate the temperature of the working environment, which increases production costs.
