Classification and application of laser engraving machine

Laser engraving machines are widely used in contemporary industrial production, from wood and paper marking to metal, mobile phone keys, high-end product production and processing, marking and engraving are inseparable from laser engraving machines. With the increase in market demand and adapting to various types of raw materials, laser engraving machines are constantly being updated. my country’s laser engraving machines have also experienced a purely foreign introduction in the early 20th century to independent research and development and production today, and they are developing rapidly.

The popular name of laser engraving machine is generally laser engraving machine, laser engraving machine, laser marking machine, laser engraving machine, etc. But its professional name is called laser marking machine. Laser cutting plotter can be divided into semiconductor laser cutting plotter, YAG laser cutting plotter, CO2 laser cutting plotter, and fiber laser cutting plotter according to the different lasers.

Laser engraving machine (Optilink Laser) was introduced from abroad at the end of the 20th century. The initial laser engraving machine models were only YAG laser engraving machine and CO2 laser marking machine. Around 1998, the number of domestic laser engraving machines reached several hundred, and the laser engraving machines have been slowly accepted by people since then. Later, the semiconductor laser was invented, followed by the semiconductor laser cutting plotter. In the continuous innovation of technology, the fiber laser was invented, and the fiber laser cutting plotter came out. As the market needs water-cooled CO2 laser engraving machine because of its large size, it cannot meet the market, radio frequency water-cooled CO2 radio frequency laser engraving machine should be produced on demand. The semiconductor laser cutting plotter has the largest share in the market. Because of its moderate price, the most widely used.

Two laser marking methods

“Thermal processing” has a high energy density laser beam (it is a concentrated energy flow), irradiated on the surface of the processed material, the surface of the material absorbs the laser energy, and generates a thermal excitation process in the irradiated area, so that the surface of the material (or Coating) temperature rises, causing phenomena such as metamorphosis, melting, ablation, and evaporation.

“Cold working” (ultraviolet) photons with very high load energy can break the chemical bonds in the material (especially organic materials) or the surrounding medium to cause the material to undergo non-thermal process damage. This kind of cold processing has special significance in laser marking processing, because it is not thermal ablation, but cold peeling that does not produce the side effects of “thermal damage” and breaks chemical bonds, so it has no effect on the inner layer and nearby areas of the processed surface. Produce heating or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit thin films of chemical substances on base materials and to cut narrow grooves on semiconductor substrates.

Application of laser cutting plotter in products

CO2 laser marking machine: mainly used for non-metals (wood, acrylic, paper, leather, etc.), at a low price.

Green laser marking machine, UV laser marking machine: mainly used for high-end and ultra-fine IC products. The price is higher, and the product is customized.

Lamp pump YAG laser marking machine: mainly used for low-demand products such as metal and plastic, and the price of laser marking machine is moderate.

Semiconductor side-pumped laser marking machine: The use surface is the same as that of the lamp pumped YAG laser marking machine, but it is more stable and affordable.

Semiconductor end-pumped laser marking machine: the same surface as the lamp pump YAG laser marking machine, stable and power-saving for high-end production, the price is higher.

Fiber laser marking machine: precise marking, power saving, maintenance-free, used in high-end products such as mobile phones and buttons. The price is high.

For different materials, you must choose the corresponding laser engraving machine to get twice the result with half the effort. When using it, pay attention to the correctness of the operation. At the same time, pay attention to the maintenance of the laser engraving machine. Do not start it without water and clean the water tank regularly. Although the principle of laser engraving machine is relatively simple, general obstacles can be self-checked, but it should be noted that once the laser engraving machine is abnormal, be sure to turn off the galvanometer and the key before checking, pay attention to safety first, and encounter problems that cannot be solved. Contact after-sales maintenance in time.
