화려한 효과! 강화 필름 절단에 나노초 고체 레이저 적용

5G 기기에 힘입어 2021년 전 세계 스마트폰 출하량은 전년 대비 6.5% 증가한 약 14억 대에 이를 것으로 예상됩니다. 엄청난 수의 휴대폰은 거대한 휴대폰 주변기기 시장을 낳았고 강화 필름도 그 중 하나입니다. 휴대폰에서 가장 취약한 부분은 화면이기 때문에 떨어뜨린 후 약간의 파열 및 누출이 발생하여 외관 및 사용에 영향을 미칩니다. 화면을 보호하기 위한 강화 필름 층.

통계에 따르면 작은 강화 필름 조각은 거대한 시장 기반에서 연간 10억 개 이상 판매될 수 있습니다. 전체 강화 필름 시장 규모는 1000억 위안이며 발전 전망은 매우 객관적이다.

Since the tempered film needs to be very close to the size of the mobile phone screen, especially the many full-screen mobile phones currently on the market, it is also necessary to consider the needs of digging holes in the film, cutting the R angle and the C angle, and the mobile phone models are different. The size of the tempered film is also different.

Diversified cutting requirements have put forward a lot of challenges for tempered film manufacturers. The traditional cutting method is mainly to cut the raw material into a shape suitable for the mobile phone model through a CNC engraving machine, while the receiver, camera and other positions need other equipment for reprocessing, the process is cumbersome and the quality is different.

The industrial-grade nanosecond solid-state laser developed and designed by RFH can cut the tempered film at one time. As we all know, laser processing has the characteristics of high efficiency, less consumables, low cost, and strong adaptability to processing materials, and the cost effect is very obvious in large-scale production. The parameters of this laser are very matched to the cutting needs of tempered film.

One is to output a 355nm ultraviolet laser. The high-energy molecules of ultraviolet photons carried by it can directly make the molecules on the surface of the tempered film material directly detach from the surface of the material. This method has low thermal effect, so ultraviolet laser processing is also called cold processing. Minimize the generation of micro-cracks in the process of cutting tempered film, and most materials have high absorption rate of ultraviolet light, even tempered films made of different raw materials can be easily cut; the second is excellent beam quality (M2 < 1.2) After focusing, the diameter of the spot is small, the cutting effect is finer, the edges are neat and slag-free, and the edge collapse is small. The third is the pulse width (<25ns), such a narrow pulse width has a small heat-affected zone during cutting. Fourth, the high flexibility of laser processing. When cutting the tempered film, you only need to draw a drawing, transmit it to the laser through the program, and complete the process of cutting and digging the tempered film in a very short time, with the repetition of single pulse to 500kHz The frequency makes this industrial-grade nanosecond solid-state laser good and fast in operation, improving the yield rate and helping enterprises reduce costs and increase efficiency.

Nowadays, laser processing has been widely used in the mobile phone industry, such as laser marking and drilling of mobile phone casings, laser cutting of mobile phone screens, metal welding of mobile phone antennas, etc. The refined processing applications provide efficient and fast solutions. When the wave of 5G terminal applications is coming, RFH's industrial-grade nanosecond solid-state lasers will continue to play an important role.
