UBOCNC laser marking machine classification and the characteristics and applications of various models:
First: according to the laser points: a: CO2 laser marking machine, semiconductor laser marking machine, YAG laser marking machine, fiber laser marking machine.
Second: According to the different laser visibility, it is divided into: UV laser marking machine (invisible), green laser marking machine (invisible laser), infrared laser marking machine (visible laser)
Third: According to the laser wavelength: 532nm laser marking machine, 808nm laser marking machine, 1064nm laser marking machine, 10.64um laser marking machine, 266nm laser marking machine. One of the most widely used is 1064nm.
Features and applications of three common UBOCNC laser marking machines:
A. Semiconductor laser marking machine: its light source uses a semiconductor array, so the light-to-light conversion efficiency is very high, reaching more than 40%; the heat loss is low, no need to be equipped with a separate cooling system; the power consumption is low, about 1800W/H. The performance of the whole machine is very stable, and it is a maintenance-free product. The maintenance-free time of the whole machine can reach 15,000 hours, which is equivalent to 10 years of maintenance-free. There is no replacement of krypton lamps and no consumables. It has excellent application characteristics in the field of metal processing, and is suitable for a variety of non-metallic materials, such as ABS, nylon, PES, PVC, etc., and is more suitable for applications that require finer and higher precision. Used in electronic components, plastic buttons, integrated circuits (IC), electrical appliances, mobile communications and other industries.
B. CO2 laser marking machine: It adopts CO2 metal (radio frequency) laser, beam expander focusing optical system and high-speed galvanometer scanner, with stable performance, long life and maintenance-free. The CO2 RF laser is a gas laser with a laser wavelength of 10.64 μm, which belongs to the mid-infrared frequency band. The CO2 laser has relatively large power and relatively high electro-optical conversion rate. Carbon dioxide lasers use CO2 gas as the working substance. Charge CO2 and other auxiliary gases into the discharge tube, when a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, and the gas molecules can release laser light. After expanding and focusing the released laser energy, it can be deflected by the scanning galvanometer for laser processing. It is mainly used in craft gifts, furniture, leather clothing, advertising signs, model making, food packaging, electronic components, pharmaceutical packaging, printing plate making, shell nameplates, etc.
C. Fiber laser marking machine: It uses fiber laser to output laser light, and then realizes the marking function through an ultra-high-speed scanning galvanometer system. Good beam quality, high reliability, long operating life, energy saving, can engrave metal materials and some non-metal materials. It is mainly used in fields that require high depth, smoothness and fineness, such as mobile phone stainless steel trim, clocks, molds, IC, mobile phone buttons and other industries. Bitmap marking can be marked on metal, plastic and other surfaces. Exquisite pictures, and the marking speed is 3~12 times that of the traditional first-generation lamp-pumped marking machine and the second-generation semiconductor marking machine.
