The sudden outbreak of the epidemic makes wearing masks a necessary habit for our daily life. In this war without gunsmoke, many heroes have made a lot of contributions. In addition to medical staff and people from all walks of life-fighting in the front line of the epidemic, there are also some unsung heroes in the optical field who have been fighting all the time!
Under the huge demand and sales volume of masks, the anti-counterfeiting work of masks is particularly important. Illegal elements have made a fortune through this epidemic, and face masks are rampant in the market.
On the issue of anti-counterfeiting, identification has naturally become a key object. In order to be able to mark the mask properly, a marking machine is needed. Now, it is not the ordinary marking machine that can control it. At this moment, laser processing technology comes out, which strikes the flood of fake masks.
Laser processing technology is a processing technology that uses the characteristics of interaction between the laser beam and material to cut, weld, surface treatment, punch, and micromachining materials (including metal and non-metal). As an advanced manufacturing technology, laser processing has been widely used in automobiles, electronics, electrical appliances, aviation, metallurgy, machinery manufacturing, and other important sectors of the national economy. It plays an increasingly important role in improving product quality, labor productivity, automation, pollution-free, reducing material consumption, and so on.
Laser marking technology
Laser marking technology is one of the biggest application fields of laser processing. Laser marking is a kind of marking method which uses high energy density laser to irradiate the part, vaporize the surface material or change the color, so as to leave a permanent mark.
Laser marking can print all kinds of characters, symbols, and patterns, and the size of characters can be from millimeter to micrometer, which has special significance for anti-counterfeiting of products. After focusing, the laser beam is like a tool, which can remove the surface material by point. The advanced nature is that the marking process is non-contact, and no mechanical extrusion or mechanical stress is generated. Therefore, the processed products will not be damaged. Because the size of the laser focus is small, the heat-affected zone is small and the machining is fine. Therefore, some processes that cannot be realized by conventional methods can be completed.
What kind of information the laser can mark is only related to the content designed in the computer. As long as the system designed in the computer can recognize, the marking machine can accurately restore the design information on the appropriate carrier. So the function of laser marking software determines the function of the laser marking system to a great extent.
Mask laser marking machine
Laser marking machine is widely used in recent years. It is a progress in the development of the times that the machine replaces the artificial. The laser marking machine of mask can operate continuously 24 hours a day, and it can be combined with the assembly line of mask for production and automatic marking. Most of the marks on the mask, such as production date, breathing valve, packaging bag, etc.
The UV laser marking machine can meet these needs. Using the mask laser marking machine instead of inkjet to mark on the mask can speed up the production process, complete the marking within seconds, complete the high automation, and increase the supply and sales volume.
Not only in the marking quality, the production of general masks is a standard assembly line project. Robots can save a lot of time and cost instead of manpower. With the addition of a laser marking machine, the assembly line cooperation is realized in the process of mask marking.
Laser marking machine has a one key processing, as long as the start-up operation can be continuous marking, no need for manual operation, automatic feeding/receiving, automatic flap, automatic marking and other functions, full-automatic positioning makes laser marking machine becomes an important part of the mask assembly line, greatly reducing the burden of the enterprise and promoting the production efficiency.
The laser marking machine is more prominent on the anti-counterfeiting mark. Before the laser marking machine came out in the market, there were ink-jet, printing, and so on in the field of marking machines. These processing features can be printed in a variety of colors, but it is easy to fall off and spread, and it can not be clear.
One way to distinguish the false masks is to look at the marks of the masks. Most of the horizontal false masks are processed with ink-jet. The words printed are not clear enough. Moreover, on this kind of melt-blown cloth, the ink is easy to disperse and will leave dot-like patterns after a long time.
The first mask of the laser marking machine is that the pattern is clear and the color is uniform. If you look carefully, you can not see the phenomenon of burr and lacing, because the ultraviolet light source laser is used. The power of the laser is smaller than that of other lasers, and it will not damage the surface of the melted spray cloth. The focus of the laser is very small. Ultra-precision processing, marking effect is more clear and smooth, giving a very comfortable feeling.
How much is a mask marking machine? According to different marking effects and marking materials, mask laser marking machine can choose to match different power. Some mask marks can use 3W to make clear and beautiful marks, while others need 5W. The power is different and the price is different. The general price range is from 4W to 10W. Varies according to power and configuration.
During the epidemic, these mask laser marking machines have played a very important role in our health and safety.
