Lasers are currently used in the field of enterprise processing to reach 44.3 percent, and ultraviolet lasers are known for fine processing, becoming one of the major mainstream lasers in fiber lasers. Why can ultraviolet laser be quickly applied in various micro-processing fields? What advantages does it have in the market? What are the unique properties of industrial micro-processing applications? Next, carefully for everyone.
solid ultraviolet laser
Solid-state ultraviolet lasers are divided into xenon lamp pumped ultraviolet lasers, krypton lamp pumped ultraviolet lasers and new laser diode pumped all-solid-state lasers by pumping methods. Generally, the integrated design is adopted, which has the characteristics of small spot, high frequency, reliable performance, strong heat dissipation ability, good beam quality and stable power.
Cold precision machining
Ultraviolet lasers have unique properties, known"Cold"Processing, with shorter wavelength and pulse width and low M2 (beam quality) laser can create a more focused spot, and can maintain the minimum heat affected zone (HAZ), in marking applications, can maximize the maintenance of the object as it is, reduce the damage during processing. Such as glass marking, ceramic engraving, glass punching, soft circuit board cutting and other applications, much processing enterprises love.
Ultraviolet laser is a kind of invisible light, the spot is small (0.07mm), the pulse width is narrow, the speed is fast, the peak output is high, the use of laser high energy laser on the workpiece for local irradiation, so that the surface material gasification or color change of photochemical reaction, so as to leave a permanent mark. High power, high pulse repetition frequency (PRF), pulse shaping and pulse splitting can all contribute to increasing the productivity of micromachining.
Common UV laser marking
In daily life, we will come into contact with all kinds of trademark signs, metal or non-metal, some with words and some with patterns, suchMidea logo, mobile phone Apple logo, keyboard keys, mobile phone keys, cup graphics, pop cans production date, etcAt present, many of these signs are realized by ultraviolet laser marking. The reason is very simple, UV laser marking, fast speed, no consumables, through the optical principle, can be printed on the surface of various substances on the permanent mark, has a great help for anti-counterfeiting.
UV Lasers Market Development
With the rapid development of science and technology, the arrival of the 5G era, especially the rapid development of the 3C industry, the speed of product updates, the requirements for equipment manufacturing are getting higher and higher, the speed is getting faster and faster, the weight is getting lighter and lighter, the price is affordable, and the processing field is becoming more and more extensive, and at the same time it becomes more complex, resulting in the development of miniaturization and precision in the parts manufacturing industry.
At present, the domestic UV laser market is in a stage of rapid development, the country attaches great importance to the development of lasers, around the"Made in China 2025, all the wayDevelopment strategy, the laser industry has been rapid development, the state has also introduced favorable support policies, China's laser market localization probability will be further enhanced.
Application areas
Ultraviolet lasers have the advantages that other lasers do not have, which can limit thermal stress, reduce damage to the workpiece during processing, and maintain the integrity of the workpiece. At present, UV lasers are used in the field of enterprise processing, mainly in four areas, glass technology, ceramic technology, plastic technology, cutting technology.
Glass process
Glass marking can be applied to: wine bottles, seasonings, beverage bottles and other industries of glass bottle packaging, can also be used for glass craft gifts on the manufacturing, crystal marking and so on.
laser cutting
UV laser equipment can be used in many fields of flexible board production, including FPC shape cutting, contour cutting, drilling, covering film window opening, soft and hard joint board uncovering and trimming, mobile phone case cutting, PCB shape cutting, etc.
Plastic Marking
Application scope: most general-purpose plastics and some engineering plastics, such as PP,PE,PBT,PET,PA,ABS,POM,PS,PC,PUS,EVA, etc., can also be used for plastic alloys such as; PC/ABS and other materials, laser marking handwriting is clear and bright, can mark black, white handwriting.
ceramic engraving
Application scope: tableware ceramics, vase ceramics, building supplies, ceramic sanitary ware, tea set ceramics, etc., ultraviolet laser ceramic marking, high peak value, small thermal effect, has natural advantages for similar ceramic fragile products, such as etching, engraving, cutting is not easy to damage the device, the process is precise, and the waste of resources is reduced.
In recent years, the trend of China's ultraviolet laser market has shown a continuous upward trend, which reflects the application and development trend of domestic ultraviolet laser from the side. Radium laser is a focus on laser accessories integration manufacturers, according to the market and user feedback, UV laser market is moving towards higher power, shorter pulse picosecond, femtosecond higher repetition rate direction.
