Introduction of fiber laser marking machine

Optical fiber laser marking machine is an advanced laser marking equipment in the world. It has the characteristics of good beam quality, small volume, fast speed, long working life, flexible and convenient installation and maintenance free. Fiber laser, a new type of international, reliable structure, small volume, small power consumption, no high voltage without large water cooling system (only about 300W), high beam quality, close to ideal beam, USB interface output control, optical scanning galvanometer, high repetition frequency of laser, high speed and no distortion.

Fiber laser is an important part of the optical fiber laser marking machine. The research of fiber laser has been started since the end of 1980s. Because it can produce ultra short pulse, it has a very broad application prospect, so the world has shown great enthusiasm for the research of fiber laser. Compared with other types of lasers, fiber lasers have the advantages of high reliability, simple structure, low price and high conversion efficiency.

  

The research of fiber laser has been started since the end of 1980s. Because it can produce ultrashort pulse, it has a very broad application prospect, so countries all over the world have shown great enthusiasm for the research of fiber laser. Compared with other types of lasers, fiber laser has the advantages of high reliability, simple structure, low price and high conversion efficiency. In recent years, fiber laser has become a hot topic in the research of laser physics. It is considered that it is a new generation of products that can completely replace solid-state laser. Fiber laser marking machine uses laser beam to make permanent marks on different material surfaces. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" the trace through the physical change of the surface material caused by the light energy, or to burn off part of the material through the light energy, showing the patterns, words, bar codes and other graphics that need to be etched.

Fiber laser has the characteristics of small volume (without water cooling device, using air cooling), good beam quality (basic mode), maintenance free, etc. fiber laser marking machine is mainly composed of laser, vibrating lens and marking card. The laser marking machine produced by fiber laser has good beam quality, its output center is 1064nm, and the service life of the whole machine is about 100000 hours Compared with other types of laser marking machine, the conversion efficiency of 2% - 10% has a great advantage. It has outstanding performance in energy saving and environmental protection.

Fiber lasers are divided into two categories: CW fiber lasers and pulsed fiber lasers. According to the power size: continuous 5W, 10W, 20W to 400W, 4000W; pulse 10W, 15W, 20W, 25W, 30W to 50W.

The characteristics and advantages of optical fiber laser marking machine: it can process many kinds of metal and non-metallic materials. Especially, it is more advantageous to mark high hardness, high melting point and brittle materials. It belongs to non-contact processing, no damage to products, no tool wear, good marking quality. The laser beam is fine, the material consumption is very small, and the heat affected area is small. The machine is highly efficient, controlled by computer and easy to realize automation. It is widely used for the marking of graphics and words in many fields such as IC chips, computer accessories, industrial bearings, clocks, electronic and communication products, aerospace devices, various automotive parts, household appliances, hardware tools, moulds, wires and cables, food packaging, jewelry, tobacco and military affairs, as well as large-scale production line operations.
