Fiber laser marking machine is a laser that uses rare-earth-doped glass fiber as the gain medium. Fiber laser marking machine has become a hot topic in laser physics research in recent years. It is unanimously considered as a new generation product that may completely replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: high power density is easily formed in the fiber under the action of the pump light, causing the laser energy level of the laser working material to "populate number inversion", when a positive feedback loop is properly added ( Forming a resonant cavity) can form a laser oscillation output. Fiber laser marking machine uses laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the physical change of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the pattern to be etched , Text, bar code and other types of graphics.
The so-called fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), and maintenance-free.
It is mainly composed of three parts: laser, vibrating lens, and marking card. The laser marking machine that uses fiber laser to produce laser has good beam quality, its output center is 1064nm, and the life of the whole machine is about 100,000 hours. Compared with other types of laser marking The life of the device is longer, and the electro-optical conversion efficiency is more than 28%. Compared with other types of laser marking machines, the conversion efficiency of 2%-10% has a great advantage. It has outstanding performance in energy saving and environmental protection.
1. It can process a variety of metal and non-metal materials. Especially for high hardness, high melting point, brittle materials, marking is more advantageous.
2. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.
3. The laser beam is thin, the processing material consumption is small, and the processing heat-affected zone is small.
4. High processing efficiency, computer control, easy to realize automation.
Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco, and military affairs, etc. Field graphics and text marking, and mass production line operations.
As a cooling device for the fiber laser marking machine, the chiller ensures that the fiber laser marking machine operates normally at a constant temperature. The chiller for fiber laser marking machine is a refrigerated industrial chiller. It has two working modes: constant temperature and intelligent temperature adjustment, and the temperature control accuracy is ±0.1℃.
Fiber lasers are divided into two categories: continuous fiber lasers and pulsed fiber lasers. According to the power size:
1. Continuous 5W, 10W, 20W to 400W, 4000W;
2. Pulse 10W, 15W, 20W, 25W, 30W to 50W.
Fiber laser marking machine is the most advanced laser marking equipment in the world today. It has the characteristics of good beam quality, small size, fast speed, long working life, flexible and convenient installation, and maintenance-free. Fiber laser, the latest international model, the most reliable structure, small size, low power consumption, no high voltage, no need for a huge water cooling system (only about 300W), high beam quality, close to ideal beam, USB interface output control, optical scanning vibration Mirror, laser repetition rate is high, high speed and no distortion.

Many people don’t know much about laser marking machines, so they don’t know what industry they will be used in, and they don’t know whether they will be used in their own industry. In fact, laser marking machines are widely used. Conceptually, The laser marking machine can be used for marking, but the specifics still need to be determined by the material. Some materials only need to be printed and do not need to use the laser, because the laser is for fine marking. The workpiece is a bit overkill, but how to know what product is suitable for laser marking machine, let's give a specific example; in the hardware industry, wrenches, measuring tools, sanitary ware, stainless steel tableware, medical equipment, luggage, leather bags, and gift industries There are also many, such as metal gifts, wooden boxes, USB flash drives, notebooks, metal watch cases, watch bottoms, spectacle frames, instruments and panels in the clock and watch industry, as well as mobile phone shells and electronic components in the packaging industry and the electronic communication industry. Laser marking. So through these we know that laser marking machines have a broad market prospect, and this market has yet to be re-developed and tapped. Therefore, laser marking machine companies should set an example, improve quality, and open up the market. When customers solve problems, they also bring profits, so in the future there will be more room for development and better market prospects. So doing the present and looking to the future is a good start to cater to the market and create performance
