5G, the Internet of Things, the era of mobile Internet, the Internet of everything, smart wearable devices represented by AR/VR, TWS wireless Bluetooth headsets, smart bracelets/watches, and their forms are diversified. With the in-depth research and development, the notable feature of these smart wearable devices is that they are developing towards high integration and high precision, and their structures are getting smaller and smaller, making them lighter, thinner and more portable.

New things and new changes are often inseparable from the blessing of scientific and technological power. Known as the "fastest knife" - laser marking technology is widely used in smart wearable devices. It is used for high-precision marking of watch straps, bluetooth headset plastic shells and electronic components. It has high efficiency and is non-contact processing. , does not generate mechanical stress, and protects the material comprehensively.

Laser marking is to use a high-energy density laser beam to act on a local area of ​​the workpiece surface such as mechanical parts and electronic components according to a predetermined trajectory, so that the surface material can be instantly vaporized or chemically changed to change color, showing a certain depth or color. Color graphics, markings last forever without fading or falling off.

The 355nm UV nanosecond laser excels in laser marking applications, and several key factors profoundly affect the marking quality. The first is the laser wavelength. The single-photon energy of 355nm ultraviolet light is high, and the material absorption rate is high. It is more friendly to smart wearable devices that use a large number of plastic materials. It can directly break molecular bonds and has a low degree of thermal influence, which is "cold processing"; Secondly, 355nm ultraviolet light is easier to focus, with high beam quality (M2 < 1.2), and the micron-level spot diameter makes the marking lines more delicate, which is manifested as very narrow line width, high contrast of logos and graphic signs, and more refined visual senses. Compared with traditional marking processes such as silk screen printing, laser marking has high flexibility, easy operation, and faster speed, which can meet the requirements of modern production efficiency and fast pace. The entire marking process has no consumables and no pollution.

In addition, the 3D marking function can also be used to "load" the laser radium engraving process on the smart wearable device, and the 3D marking pattern can be output through computer control, which can carry out precise texture engraving on the appearance of the smart wearable device, making it full of technology and fashion sense. .
