Laser cutting machine is a high-tech intelligent equipment which integrates numerical control technology, laser cutting technology and inverter power supply technology. The development of laser cutting technology is based on the common progress of computer control, burning laser pen optics and power electronics. PIC system, belonging to the older board control system, can be integrated into the ordinary computer to run, the use of background software to control the analog signal transmission, the control system, although old, but are fully open system.

Laser cutting machine processing as an advanced means of material cutting, has been more and more accepted by sheet metal producers. With the computer control technology and optical technology continues to progress, people for their processing capacity expectations are getting higher and higher, this expectation is not only able to cut, but also cut well and cut fast expectations. Metal laser cutting machine is a solid fiber module as a source of excitation of the metal laser output of high energy density of the laser beam, and focus on the workpiece surface, so that the workpiece area by the spot light instantaneous melting and gasification, through the computer control CNC machine The system moves the spot position to achieve automatic cutting. It is a set of 3000mw laser pointer technology, numerical control technology, precision machinery technology in one of the high-tech equipment. And can give the answer, of course, can not be separated from the performance of processing machines, while the quality of processed materials also directly affect the effectiveness of the answer.
In general, the shorter the pulse width, it is difficult to obtain high average power, therefore, from this point of view, the short pulse is at the expense of the average power at the expense. In addition, the narrower the pulse width, the greater the spectral width, therefore, the color difference will also affect the processing effect. Followed by the effect of wavelength, for the general material, the wavelength of the etching effect is not significant, only in the transparent material (such as SiO2) when the processing is considered, and should consider the wavelength problem. As mentioned earlier, transparent materials have a strong absorption of ultraviolet light, and for visible and infrared light transmission rate is very high. So it is usually the ultra-fast laser triple frequency light for processing. For tens of femtosecond lasers, the spectral width of 20nm, or even 50nm, so the third frequency efficiency is very low. While the picosecond laser can get a higher triple frequency output.
For a set of laser fine processing system, in addition to the laser, the entire system platform to build, software control is also an important issue. Any one of the shortcomings, are sufficient to affect the performance of the entire system. Laser processing is the use of light energy through the lens after focusing on the focus to achieve a high energy density, by the photothermal effect to the processing. Laser processing does not require tools, processing speed, surface deformation is small, can process a variety of materials. Use a high powered laser pointer beam to perform various materials such as punching, cutting, scribing, welding, heat treatment, etc. Some substances with metastable energy levels absorb light energy at the excitation of extraneous photons so that the number of atoms at high energy level is greater than the number of atoms in the low energy level - the number of particles is reversed, and if there is a beam of light, Energy is equal to the two can be the corresponding difference, then it will produce stimulated radiation, the output of a lot of light energy.
Compared with the CO2 laser, the processing time of the fiber laser is significantly shorter when the power is the same, the processing material and the thickness are the same. In addition, the power consumption of fiber lasers is significantly lower than that of CO2 5000mw green laser. Typically, the efficiency of fiber lasers is greater than 35% (YLS-ECO series lasers are close to 50% efficiency), far greater than CO2 lasers. Easy to use and low maintenance, fiber lasers are ideal for metal cutting solutions.
Through the built-in lidar, send and receive back and forth the laser line, but also inxx navigation within the sweeping robot to accurately locate their own and furniture environment, automatically create a whole house 2D map, lay the foundation for full coverage clean, and through the calculation of Luban calculation, In the establishment of a good map, the initiative 1000mw green laser will be greater than 45 square meters of the region to divide, and clean each area, will insist on bow-type straight line to ensure that the cleaning without missing, consumers do not have to worry about where there is no sweep. In recent years, the frequency of sweeping machines has increased, but most of them have been deliberately avoided by the navigation function of sweeping machines. The reason is that the cost of sweeping machines is increased, but the navigation function of the sweepers has become a necessity Demand, within the sweeping machine with its powerful navigation function, in the future market within the sweeping machine prospects are very impressive.
