With the rapid development of industrial manufacturing and high-end manufacturing in China, new requirements have been put forward for high-precision processing, and the laser manufacturing process has also changed from the original nanosecond laser to ultra-fast lasers such as picoseconds and femtoseconds.

Since 2017, the domestic ultrafast picosecond and femtosecond laser technology has developed rapidly, and its power and stability have been continuously improved, and it has been catching up with the advanced level of Europe and the United States. The localization of ultrafast lasers has broken the foreign monopoly, and the most direct effect is that the purchase cost of ultrafast lasers, which was originally expensive, has been drastically reduced. Before 2017, the price of a 20-watt picosecond laser was more than 1.1 million yuan, resulting in an integrated ultra-fast laser micromachining equipment generally exceeding 2.8 million. The high cost of use limits the large-scale promotion and application of precision laser processing. An important reason. Nowadays, the prices of ultrafast lasers and related core components have dropped significantly, making preparations for large-scale applications of laser micromachining in advance. In terms of cooling ancillary products, a domestic laser precision chiller specially equipped for ultrafast lasers has also been born.

In the past, the news about ultra-fast laser cooling equipment was only heard and not visible. There were many rumors and news about ultra-fast laser cooling equipment in the market. Until October, Teyu Electromechanical officially demonstrated this product to the industry. This is the first time this domestically advanced laser chiller has appeared in the industry.

Domestic ultra-fast laser chiller is of great significance

Today, the power application of ultrafast lasers has been greatly improved, from the original 5-20 watts to 20 watts, 30 watts, and 50 watts. As we all know, the advantage of ultrafast laser applications lies in its non-contact surface and high precision. Therefore, it is widely used in some consumer electronic components micro-manufacturing, refined circuits, film cutting, brittle materials, biomedical and other fields. The high-precision and stable processing effect of ultrafast laser requires strict requirements on its temperature control effect. As the power of the laser increases, the more difficult it is to ensure the accuracy of temperature control, resulting in processing results that are often indistinguishable from each other.

The continuous breakthrough of ultrafast laser technology has put forward higher requirements for ultra-high precision cooling equipment. In the past, high-precision temperature-controlled chillers were an industrial problem. Many previous applications could only find foreign imported products.

The temperature control accuracy of this CWUP-20 AI ultra-fast laser water chiller launched by 　　 Teyu Electromechanical is ±0.1℃, which has reached the leading level in foreign countries, and at the same time filled the technical gap in this subdivision of our country. This product has a small body and a compact design, which can be used in multiple application environments. The water temperature accuracy is not affected by environmental factors, and the temperature control accuracy stability is maintained by itself.

Application expansion of ultra-fast laser glass cutting

In the past few years, the application of ultrafast lasers has expanded from infrared light sources to green and ultraviolet ultrafast light sources, and the scope of application has become more extensive. From silicon wafers, PCB and FPC circuit boards, ceramics, thermal polymer materials, etc., to solar cell grooving and dicing, OLED, HDI and other processing applications, the large-scale application of ultrafast laser micromachining is officially launched now, and the future The development potential is huge.

According to the statistics of the China Electronic Information Industry Association, the revenue of my country's electronics manufacturing industry in 2018 was 10.6 trillion yuan, an increase of 9.0%. Among them, the production of mobile phones, computers, and color TVs in my country accounted for more than 90%, 90%, and 70% of the total global output; the production scale of each link in the photovoltaic industry chain has accounted for more than 50% of the world for many consecutive years, ranking first in the world; Chinese mainland enterprises The display panel shipment area ranks first in the world. In the manufacturing process of these major industries, many micro-cutting, micro-drilling and other processes can be used with ultra-fast lasers. In the future, it will be a process to replace traditional processes to improve efficiency, especially in the past that use mechanical tools and drills. In scenes where the accuracy is not up to the requirements and the damage rate is high, non-contact, ultra-precision laser processing equipment may be used in the future. In the future, consumer electronics manufacturing can bring more than tens of billions of equipment needs to the ultrafast laser micromachining market every year.

Here we focus on the application scenarios of glass and screen. The earliest and most concentrated applications of ultra-fast lasers in industrial applications are around mobile phone parts, from blind holes for cameras, cutting of camera slides, to cutting of bangs and drip grooves on full screens, to cutting of whole glass on mobile phone touch screens. Forming, the application of laser to cell phone glass parts has been very mature.

Using ultra-fast laser to cut glass has higher cutting efficiency than traditional knives, and has a better cutting edge collapse effect, which reduces grinding effort and eliminates the cost of tool wear and replacement. Nowadays, the demand for laser processing of glass for consumer electronics applications continues to develop. In the past two years, sales of smart watches have skyrocketed, and laser cutting such as automotive commercial displays and dashboard camera covers has also expanded rapidly.

In terms of new displays, the flexible AMOLED production line has landed in my country and achieved mass production, leading the development of the global large-size ultra-high-definition display industry. A group of outstanding Chinese companies, such as BOE, TCL China Star, Xingxing Technology, and Tianma Microelectronics, seize more global market shares. In the future, laser technology will also be used in the full-screen cutting of large panels, bringing more opportunities to precision laser micromachining
