Fiber laser marking machine
Principle of Fiber Laser Marking Machine : Fiber laser marking machine uses laser beam to mark permanent marks 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
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, so that the gas emits 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 : The working principle of semiconductor laser pumped all-solid-state laser (DPSSL) for laser marking is to use high-power semiconductor quantum well lasers instead of gas lamps to pump solid-state crystals as gain medium laser resonant cavities to produce them. Lasers with new wavelengths produce lasers with wavelengths such as SHG and THG when they are mixed using crystal back-up 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 system is mainly composed of scanning galvanometer, computer and 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. (The He-Ne laser marking machine must be turned on for 30 minutes to be stable. 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 will be caused by the compound. 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 models, 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:
1. Light-saving: The life of semiconductor diode is up to 10,000 hours. Based on eight hours of work per day, it can be used for up to three years without replacing consumables. The life of dysprosium lamps is only a few hundred hours. Maintenance system.
2. Power saving: The power consumption of semiconductor laser marking machine is only about 2KW, while the lamp pump laser marking machine needs about 6KW, that is, the semiconductor laser marking machine can save 4 degrees of electricity per hour, and one degree of electricity per hour according to industrial electricity. 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 .
3. Better marking effect: the laser pumped laser has better monochromaticity, the laser mode is better, the light spot after the laser is focused is smaller, the energy is more concentrated, and a better marking effect can be achieved. The marking machine can make the technological effect that the lamp pump laser marking machine cannot reach.
4. Maintenance-free: The lamp pump laser marking machine needs to be replaced frequently, and the light path must be re-adjusted each time the lamp is changed. 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.
