Application of DPSS solid-state UV laser in enterprise processing field

Lasers are currently used in the processing field of enterprises to reach 44.3%, and ultraviolet lasers are known for their fine processing and become one of the mainstream lasers of fiber lasers. Why can ultraviolet lasers be quickly applied in various micromachining fields? What are its advantages in the market? What are the unique attributes in industrial micromachining applications? Next, I will come carefully for everyone.

Solid-state ultraviolet laser

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

Cold + precision machining

Ultraviolet lasers have unique properties, which are called “cold” processing. Lasers with shorter wavelengths and pulse widths and lower M2 (beam quality) can create a more focused spot and maintain the smallest heat affected zone ( HAZ), in the marking application, it can keep the object as it is to the greatest extent and reduce the damage during processing. Such as glass marking, ceramic carving, glass perforation, flexible circuit board cutting, etc., are very popular among processing companies.

Ultraviolet laser is a kind of light invisible to the naked eye. It has a small spot (0.07mm), narrow pulse width, fast speed, and high peak output. The high-energy laser is used to locally irradiate the workpiece to vaporize the surface material or change the color. The photochemical reaction leaves a permanent mark. High power, high pulse repetition frequency (PRF), pulse shaping and pulse splitting can all contribute to improving the productivity of micromachining.

UV laser market development

In daily life, we will come into contact with a variety of trademark signs, including metal or non-metal, some with text and some with patterns, such as the Midea logo, mobile phone Apple logo, keyboard keys, mobile phone keys, and cup graphics. , Can production date, etc. Many of these marks are currently realized by UV laser marking. The reason is simple. UV laser marking is fast and without consumables. Through optical principles, permanent marks can be printed on the surface of various substances, which is of great help to anti-counterfeiting.

 With the rapid development of science and technology, the arrival of the 5G era, especially the rapid development of the 3C industry, rapid product update, higher and higher requirements for equipment manufacturing, faster and faster speeds, lighter weights, affordable prices, and processing fields It is becoming more and more extensive, and at the same time becoming more complex, leading to the development of miniaturization and precision in the manufacturing of parts and components.

At present, the domestic UV laser market is in a stage of rapid development. The country attaches great importance to the development of lasers. Following the development strategy of “Made in China 2025, One Belt One Road”, the laser industry has developed rapidly, and the country has successively introduced favorable supporting policies. The probability of localization in the laser market will further increase.

Application areas of UV lasers

Ultraviolet lasers have the advantages that other lasers do not have. They 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 enterprise processing fields, mainly in four areas, glass crafts, ceramic crafts, plastic crafts, and cutting crafts.

Glashandwerk: Die Glasmarkierung kann auf die Verpackung von Glasflaschen in verschiedenen Branchen wie Weinflaschen, Gewürzflaschen, Getränkeflaschen usw. aufgebracht werden. Sie kann auch bei der Herstellung von Glashandwerksgeschenken, Kristallmarkierungen usw. verwendet werden.

Laserschneiden: UV-Lasergeräte können in vielen Bereichen bei der Herstellung flexibler Leiterplatten eingesetzt werden, einschließlich FPC-Profilschneiden, Konturschneiden, Bohren, Öffnen von Deckfolien, Freilegen und Beschneiden von Weich- und Hartplatten, Schneiden von Handyhüllen, Schneiden von Leiterplattenformen, usw.

Kunststoffmarkierung: Der Anwendungsbereich umfasst die meisten allgemeinen Kunststoffe und einige technische Kunststoffe wie PP, PE, PBT, PET, PA, ABS, POM, PS, PC, PUS, EVA usw. Es kann auch für Kunststofflegierungen verwendet werden wie zum Beispiel; PC/ABS und andere Materialien, die per Laser markierte Handschrift ist klar und hell, und Schwarz-Weiß-Handschrift kann markiert werden.

Keramisches Schnitzen: Der Anwendungsbereich umfasst Geschirrkeramik, Vasenkeramik, Baubedarf, keramische Sanitärkeramik, Teegeschirrkeramik usw., UV-Laser-Keramikmarkierung, hoher Spitzenwert, geringer thermischer Effekt, hat natürliche Vorteile für ähnliche zerbrechliche Keramikprodukte, wie z da Ätzen, Gravieren und Schneiden das Gerät nicht leicht beschädigen, und der Prozess präzise ist, was die Verschwendung von Ressourcen reduziert.

In den letzten Jahren hat der chinesische UV-Lasermarkt einen kontinuierlichen Aufwärtstrend gezeigt, der den Anwendungs- und Entwicklungstrend einheimischer UV-Laser von der Seite widerspiegelt. Laut Rückmeldungen des Marktes und der Anwender bewegt sich der UV-Lasermarkt in Richtung höherer Leistung, kürzerer Pikosekundenpulse und höherer Wiederholraten im Femtosekundenbereich.
