In the past two years, shared bikes have gone from 0 to 100, and red, orange, yellow, green, blue, and purple have gathered together. As long as we just search with our mobile phone, all kinds of bicycle sharing apps can fill the screen. It can be seen that shared bikes have successfully entered an explosive growth period, and shared bikes such as Mobike, ofo, and Xiaolan have gradually entered our lives. Their emergence quickly resolved the headache of the "last mile" and was called "the last perfect piece of urban traffic" by the media.
However, while the number of bikes has soared, shared bikes are also facing many problems. In the process of user renting, scanning the QR code to obtain the smart lock password to pick up the car is the mode currently adopted by most shared bikes. But after the emergence of bicycle sharing in various cities, the QR code was damaged.
As a renting family, I deeply powerless that after the QR code of a shared bicycle is destroyed, we ca n’t borrow it at all. Such bikes are owned by some people. For situations like this, the official company had a brilliant idea, and mark a laser QR code on the shared bicycle, recorded the owner's information in the QR code,then bikes will be easy to find.
The reason why laser two-dimensional code marking can help police guard against theft is that the laser-marked text and graphics are not only clear and fine, but also cannot be easily erased, modified. It can effectively prevent qr codes on shareing bikes from being scratched and damaged.
According to industry experts, laser marking mainly uses a high-energy-density laser to locally irradiate the workpiece, so that the surface material is vaporized or a chemical reaction of color changes occurs, leaving a permanent marking method. Laser marking can print a variety of characters, patterns, etc., and has a small heat affected area, fine processing, low cost, easy operation, and no pollution.
For many years, Sino-Galvo Tech. has worked in the field of metal laser processing with deep technical experience. The general-purpose fiber laser marking machine launched by it uses international high-quality fiber lasers and is widely used in electronic components and hardware tools, electrical products, consumer goods, sensors, automotive parts, can mark various fine and complex patterns on the surface of the product.
