Anwendung von UV-Lasern in industriellen Prozessen 

 

Laser werden derzeit in 44,3 % der Verarbeitungsbereiche von Unternehmen eingesetzt, und UV-Laser sind berühmt für die Feinbearbeitung und werden zu einem der wichtigsten Mainstream-Laser von Faserlasern. Warum können UV-Laser schnell in verschiedenen Bereichen der Mikrobearbeitung eingesetzt werden? Welche Vorteile hat es auf dem Markt? Was sind die einzigartigen Eigenschaften für industrielle Mikrobearbeitungsanwendungen? Als nächstes kommen wir sorgfältig zu Ihnen.

 

 

Festkörper-UV-Laser

 

UV-Festkörperlaser werden unterteilt in Xenonlampen-gepumpte UV-Laser, Kryptonlampen-gepumpte UV-Laser und neue Laserdioden-gepumpte Festkörperlaser nach dem Pumpverfahren. Im Allgemeinen wird das integrierte Design verwendet, das die Eigenschaften eines kleinen Flecks, einer hohen Wiederholfrequenz, einer zuverlässigen Leistung, einer starken Wärmeableitung, einer guten Strahlqualität und einer stabilen Leistung aufweist.

 

 

Kalt- und Präzisionsbearbeitung

 

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 the optical principle, 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 achieved rapid development, and the country has successively issued 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 opening, flex-rigid board uncovering and trimming, mobile phone case cutting, PCB shape cutting and many more

 

plastic marking

 

Scope of application: 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, The handwriting of laser marking is clear and bright, and black and white handwriting can be marked.

 

ceramic carving

 

Application range: tableware ceramics, vase ceramics, building supplies, ceramic bathroom, tea set ceramics, etc., UV laser ceramic marking, high peak value, small thermal effect, natural advantages for similar ceramic fragile products, such as etching, engraving, cutting is not easy to damage The device and the process are precise, and the waste of resources is reduced.

 

 

In recent years, the trend of my country's ultraviolet laser market has shown a continuous upward trend, which reflects the application and development trend of domestic ultraviolet lasers from the side. RFG Laser is a manufacturer specializing in the integration of laser accessories. According to the feedback from the market and users, the UV laser market is developing towards higher power, shorter pulse picoseconds, and higher femtosecond repetition rates.
