Laser Marking System is a combination of laser technology and optical, mechanical and electrical integration system of computer technology, today's laser marking technology and computer technology for the development of laser marking machine has brought unprecedented opportunities and challenges

 At present, galvanometer scanning laser marking system, the hardware control circuit is based on ISA bus or PCI bus computers designed to be installed on the computer motherboard or PCI bus, ISA bus expansion slot. This approach allows a computer controlled laser marking machine is limited by the number of units (now most of the situation is a computer controlled laser marking machine 1). In addition, the hardware installed on the computer's motherboard, to the stable operation of the system impact, reducing the laser marking system stability, while also increasing the laser marking machine cost and size.
 
The emergence and development of USB makes the laser marking control circuit from the computer hardware, ISA bus or PCI bus as possible. USB2.0 transfer rate up to 480Mbit / s, fully capable of laser marking of the data transmission rate requirements, and that it can support a single computer connected to 127 devices simultaneously, so that you can use a computer simultaneously controls several laser marking machine without additional charge, and laser marking machine can be sold without the computer, thus reducing the price of laser marking machine.
 
Laser marking machine is now used Nd: YAG lasers are based on krypton or xenon lamp to lamp pumped, the pump efficiency is very low, resulting in the overall efficiency of the laser can only reach 2% to 5%, which means most of the The increase in the pump light is converted into electric power energy. Thus, the laser marking machine is equipped with a large cooling system, its volume can be accounted for 40% of the volume of the entire system.
 
Emerged in recent years, semiconductor laser-pumped solid-state laser, the overall conversion efficiency of up to 20% or more, which can greatly reduce the size of the laser cooling system, which is laser marking machine to the lighter and the direction of creating small conditions. The high-power fiber lasers in recent years, its thermal properties, and conversion efficiency (a semiconductor laser pumped solid state lasers 2 times more), low lasing threshold, tunable range, beam quality, maintenance-free and low cost, production flexibility, and other significant advantages, even for a laser marking to the lighter and more compact direction.
 
More and more people begin to pay attention to laser marking technology and try to find its application in industry, all kinds of new laser marking machine occur one after another, with its unique advantages to replacethe traditional markers, such as: stamping, printing, chemical corrosion, etc. , in a variety of mechanical parts, electronic components, integrated circuits modules, instruments, meters, motor nameplate, tools and even food packaging and other objects on the surface, marking out the Chinese characters, English characters, numbers, graphics, etc., which have made in these areas wide range of applications. Some developed countries have international laser marking technology for industrial processing technology standards, China also attaches great importance to this technology, the State Science and Technology Commission has the technology as the "Eighth Five Torch Plan" for development and promotion. Now it has attracted more and more manufacturers of domestic importance, and will certainly replace the traditional marker technology, to inject new vitality into production. Therefore, including laser cutting machine, laser engraving machine, laser marking machine development potential and broad market prospects are enormous.
