UV laser marking machine logo QR code barcode laser printing

In industrial manufacturing, packaging labels and information labels of various products are inseparable. The most familiar ones are some signs, trademarks, company names, icons, logos and other information. Of course, there are also some labels, barcodes, two-dimensional codes, dates, numbers, characters, numbers, and English that we see on commodities in our daily life. and other information.

The existence of this type of information requires the help of equipment to be designed according to the user's thoughts. The scope is quite broad, but it is precisely because of this that the industry is inextricably linked and promotes the continuous development of society. As one of the types of laser marking equipment, UV laser marking machine is also an indispensable marking equipment in the marking industry, which can help users to mark and identify simple or complex information. indispensable part.

The working principle of the UV laser Leadtech Coding machine is realized by photochemical ablation, that is to say, relying on the high energy of the laser to generate objects or chemical reactions on the surface of the object, and then A pattern that forms a mark. The cold light source is mainly used, the wavelength is only 355nm, the diameter of the focusing spot is smaller, the absorption rate of various materials to ultraviolet light is high, and the thermal influence is also small (negligible), so the marking effect should be more exquisite. ,fine. For the identification information solution of any industry, it can complete the task delicately, and it plays an especially important role in the identification industry.

The wavelength of the fiber laser marking machine is 1064NM, which belongs to infrared light at noon, which is easy to generate high temperature, and some materials will burn The feeling of focus. However, today's fiber laser marking machine is the mainstream of the market in metal material marking, and the fiber laser marking machine on the metal will not cause much change to the metal surface. The UV laser marking machine is suitable for processing almost all materials except copper. Ultraviolet is used in less metal, and the price of ultraviolet marking machine is expensive and the power is relatively low (currently, it is basically 3W and 5W).

The structure of the UV marking machine is the same as that of the fiber laser marking machine. The optical devices of the fiber laser marking machine and the UV marking machine cannot be universal. The wavelength of the laser is 355nm, the wavelength of the fiber laser is 1064nm, and the wavelength of the ultraviolet laser is the wavelength after frequency doubling on the basis of the wavelength of 1064nm through technology. The technical difficulty is higher. Compared with the fiber laser marking, the galvanometer and lens of the ultraviolet marking machine The thickness of the machine coating is different from the material, so it cannot be used universally.
