The repetition accuracy of the UV laser is ±0.1μm, and the spot can reach 10μm after focusing. Compared with the carbon dioxide laser marking machine and the fiber laser marking machine, the marking effect is better, and it can carry out ultra-fine marking and special materials. Therefore, it is especially suitable for food material marking, medical packaging marking, micro-drilling, high-speed division of glass materials and porcelain materials, and complex line marking of silicon wafers and wafers. Wider range of application; small heat affected area, no thermal effect, no material scorching problem; fast marking speed and high efficiency; stable performance, small size and low power consumption of the whole machine. When the optical fiber is made of plastic, the surface of the plastic may foam, and the hand feels a bumpy feeling. Ultraviolet laser marking machine solves this problem very well. Ultraviolet laser marking machine laser processing is cold processing, because the high-energy molecules of ultraviolet photons directly separate the molecules on the metal or non-metallic materials that need to be processed. However, This detachment leads to the separation of molecules and materials. This way of working does not generate heat. Because of the way of working that does not generate heat, the UV laser processing method becomes cold processing, which is also different from traditional fiber lasers.
Ultraviolet laser marking machine is a new type of non-contact processing. The ultraviolet light beam with high energy density emitted by the laser acts on the surface of the silicone material, causing the surface material to vaporize or undergo a chemical reaction of color change, thereby leaving persistence. A marking method of marking is developed by a 355nm ultraviolet laser. The machine adopts the third-order intracavity frequency doubling technology. Compared with the red light, the beam quality is finer. It will not change the material deformation outside the area, and can engrave ultra-fine two-dimensional codes, serial numbers, serial numbers, patterns, texts, LOGOs, etc. on silica gel, plastic, ceramics, and glass.
