Under the current development trend, the market demand for mobile phone functions tends to be diversified, especially in the camera, good shooting, sensitive, deep focusing and other requirements, making three shots four shots began to be popular, and CNC processing shortboard more prominent, laser to replace CNC has become an inevitable trend.
Mobile phone glass camera industry market demand is strong, while fierce competition leads to generally low prices. In the actual production process of the traditional CNC manufacturing process, there are problems such as low processing efficiency and yield, frequent replacement of tool wheels, and harsh processing environment, which make the industry enter the Red Sea.
Ultrafine laser cutting glass principle: Ultrafine laser through the focusing head focused micron beam, with peak power density. When the beam is acted on the glass material, the light intensity of the center of the beam is lower than that of the edge, which makes the refractive index of the center of the material change more than that of the edge, the propagation speed of the beam center is slower than that of the edge, and the nonlinear optical Kerr effect of the beam generates self-focusing, which continues to improve the power density. Until a certain energy threshold is reached, the material produces a low-density plasma that reduces the central refractive index of the material and defocuses the beam. In actual glass cutting, the optimization of the focusing system and focal length enables a repetitive focusing/defocusing process and a stable perforation.
The continuous growth of the laser equipment market capacity, for high-end intelligent manufacturing has brought good momentum, not only in the existing camera industry, display, vehicle, semiconductor and other industries are also in the laser equipment in the blessing of manufacturing improved, the market is also enjoying the huge benefits brought by laser manufacturing. Although affected by the epidemic, the economic system has changed to a certain extent, but this is always temporary, with the good control of the epidemic, laser application will complete the perfect baton to the traditional industry, in the process of high-end intelligent manufacturing, play its unique charm to help technology forward.
