Application of Ultraviolet Laser in Industrial Process

 

Lasers are currently used in 44.3% of enterprise processing fields, and ultraviolet lasers are famous for fine processing and become one of the major mainstream lasers of fiber lasers. Why can UV lasers be quickly used in various micromachining fields? What advantages does it have in the market? What are the unique properties for industrial micromachining applications? Next, we will come to you carefully.

 

Solid-state UV lasers

Solid-state UV lasers are divided into xenon lamp pumped UV lasers, krypton lamp pumped UV lasers and new laser diode-pumped all-solid-state lasers according to the pumping method. Generally, the integrated design is adopted, which has the characteristics of small spot, high repetition frequency, reliable performance, strong heat dissipation, good beam quality and stable power.

 

 

Cold + Precision Machining

 

Ultraviolet lasers have unique properties known as "cold" processing, using lasers with shorter wavelengths and pulse widths and lower M2 (beam quality) to create a more focused spot while maintaining a minimal heat-affected zone ( HAZ), in marking applications, it can keep the original object to the greatest extent and reduce damage during processing. Applications such as glass marking, ceramic engraving, glass drilling, and flexible circuit board cutting are favored by processing companies.

 

Ultraviolet laser is a kind of light invisible to the naked eye, with a small spot (0.07mm), narrow pulse width, fast speed and high peak output. The high-energy laser is used to partially irradiate the workpiece, so that the surface material vaporizes or changes color. photochemical reaction, thereby leaving 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, some are metal or non-metal, some use words and some use patterns, such as Midea logo, mobile phone Apple logo, keyboard keys, mobile phone keys, cup pictures and texts , production date of cans, etc. Many of these signs are currently marked by UV lasers. The reason is very simple. Ultraviolet laser marking is fast and has no consumables. Through optical principles, permanent marks can be printed on the surface of various substances, which is of great help to anti-counterfeiting.

 

Ultraviolet Laser 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 product update speed is fast, and the requirements for equipment manufacturing are getting higher and higher. It is becoming more and more extensive and at the same time more complex, resulting in the development of miniaturization and precision in the manufacturing of components.

 

At present, the domestic ultraviolet laser market is in a stage of rapid development, and the country attaches great importance to the development of lasers. Focusing on the development strategy of "Made in China in 2025, One Road, One Belt One Road", the laser industry has developed rapidly, and the country has successively introduced favorable support policies. The probability of localization in the laser market will be further improved.

 

 

Application field

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, ultraviolet lasers are used in the field of enterprise processing, mainly in four fields, glass technology, ceramic technology, plastic technology, and cutting technology.

 

glass craft

 

Glass marking can be applied to: glass bottle packaging in various industries such as wine bottles, seasoning bottles, beverage bottles, etc., and can also be used for the manufacture of glass craft gifts, crystal marking, etc.

 

laser cutting

 

Ultraviolet laser equipment can be used in many fields in the production of flexible boards, including FPC shape cutting, contour cutting, drilling, cover film window opening, flex-rigid board uncovering and trimming, mobile phone case cutting, PCB shape cutting and many more

 

plastic marking

 

Ámbito de aplicación: la mayoría de los plásticos de uso general y algunos plásticos de ingeniería, como PP, PE, PBT, PET, PA, ABS, POM, PS, PC, PUS, EVA, etc., también se pueden usar para aleaciones plásticas como ; PC/ABS y otros materiales, la escritura a mano del marcado láser es clara y brillante, y se puede marcar la escritura a mano en blanco y negro.

 

talla de cerámica

 

Rango de aplicación: vajilla de cerámica, jarrón de cerámica, materiales de construcción, baño de cerámica, juego de té de cerámica, etc., marcado de cerámica con láser UV, alto valor máximo, pequeño efecto térmico, ventajas naturales para productos frágiles de cerámica similares, como grabado, grabado, corte no es fácil de dañar El dispositivo y el proceso son precisos, y se reduce el desperdicio de recursos.
