Laser marking machine is the use of laser beam on the surfaces of different materials on permanent mark. Effect of marking is exposed through the deep material surface material evaporation, so as to cut the exquisite design, logo and text, laser marking machine mainly consists of CO2, laser marking machine semiconductor laser marking machine, laser marking machine, optical fiber and YAG laser marking machine, laser marking machine is mainly used in some of the more precise and higher occasions. Used in electronic components, integrated circuits, electrical appliances, mobile phone communications, hardware, tool accessories, precision instruments, watches, glasses jewelry accessories, auto parts, plastic buttons, building materials, PVC pipe. The following about several kinds of laser marking machine with content (IC):
Fiber laser marking machine
Fiber laser marking machine principle: fiber laser marking machine is the laser beam on the surfaces of different materials on permanent markers used. Effect of marking is exposed deep substance through the surface material evaporation, or by light can cause chemical and physical changes of the surface material "carved out" marks, or burned part the material through the light, showing the required etching patterns, text, and other types of bar code graphics. The fiber laser marking machine is the marking machine is the use of fiber laser, fiber laser has the advantages of small volume (without water cooling, air cooling), light (good quality, maintenance free characteristics of fundamental mode).
Fiber laser marking machine is mainly composed of: fiber laser marking machine is mainly composed of fiber lasers, high-speed scanning galvanometer, marking software, computer cabinet and other components. The fiber laser is the main core components.
Fiber laser marking machine has the advantages of fiber laser marking machine is the most advanced laser marking equipment, with good beam quality, small volume, high speed, long service life, convenient installation and maintenance etc.. Widely used in marking graphics and text fields of integrated circuit chip, computer accessories, industrial bearings, watch, electronic and telecommunication products, aerospace devices, auto parts, household appliances, hardware tools, moulds, wire and cable, food packaging, jewelry, tobacco and military things, and mass production line for the industry.
CO2 laser marking machine
CO2 laser marking machine principle: CO2 laser marking machine which is carbon dioxide laser marking machine (CO2 is carbon dioxide). The laser galvanometer is using CO2 gas as the working medium of the marking machine,.Co2 laser marking machine is CO2 laser with CO2 gas as medium, CO2 and other auxiliary gas into the discharge pipe at high pressure. On the electrode, the glow discharge is generated in the discharge tube, the gas release wavelength of 10.64um laser, the laser energy is amplified by scanning and F - theta mirror focus, control standard control card in the computer and laser, image, text, figures and lines on the workpiece according to the user requirements for marking.
CO2 laser marking machine, CO2 laser marking machine is mainly composed of CO2 lasers, 10.64 mirror, 10.64 beam expander, CO2 laser power, scanning galvanometer, computer control, laser control card, laser control software, laser machine, laser circulating water system and electric control system and other parts.
CO2 laser marking machine main features: use the carbon dioxide laser, is a common type, after focusing, small volume, high degree of integration. It is suitable for the vast number of non metal material marking, such as CO2 laser marking machine, paper packaging, plastic products, paper labels, leather cloth, glass ceramics, plastic, resin bamboo products, PCB plate,.Co2 laser is far infrared wavelength band 10.64um gas lasers, using CO2 gas into the discharge pipe as the lasing medium, when the high voltage on the electrode, the glow discharge is generated in the discharge tube, which can cause the gas molecules released from the laser, the laser energy amplification after the formation of laser beam the processing of materials.
Semiconductor laser marking machine
The principle of the semiconductor laser marking machine, laser diode pumped solid-state laser (DPSSL) is the working principle of laser marking is the use of high power semiconductor quantum well lasers instead of gas lamp pumped solid crystal for laser resonant cavity laser gain medium, so as to generate a new wavelength, in the preparation of frequency mixing cross laser should produce SHG, THG the use of wavelength crystal. Through the design from the incoming retest, the Ministry of equipment production, inspection, assembly and debugging to the finished product inspection of the laser marking process, operating procedures and quality standards established.
Semiconductor laser marking machine: mainly consists of four systems: optical system, circuit system, water system and control system. The optical system is mainly composed of red, full, half, anti anti module, Q, field lens, extender lens, scanning and other components. The circuit system is mainly composed of a control circuit (control box), laser power supply, Q power supply, scanning power supply. The control system is mainly composed of the scanning mirror, computer, control software (board and other components. The waterway system is mainly composed of a water tank, a water pipe, a circulating water).
Semiconductor laser marking machine has the advantages of laser beam mode, high conversion efficiency, low power consumption, maintenance free; some photoelectric measurement equipment manufacturers to measure the laser light from the he - Ne laser into the laser diode, in order to achieve the best life of the machine (He Ne laser average life of 10 4hr diode laser lifetime is 10 ^ - ^ 5hr, a difference of ten times), especially suitable for long time operation; instant can achieve the switching effect, suitable for communication purposes and semiconductor laser marking.
