The lunar New Year holiday is over, the processing enterprises have also put into work. After a short holiday, laser cutting machine of the focus lens, reflect lens, lens protection will inevitably be some pollution, such as water pollution and dust pollution and so on. So, your laser lens clean?



New Year new atmosphere, in the New Year, we also need to clean the laser lens, can guarantee the stability of laser cutting machine. As a result, China laser equipment factory group to explain in the laser cutting machine laser lens right cleaning method.



1, take the lenses must wear gloves or rubber gloves, because the hand of the dirt and oil droplets will dirty lenses, cause performance degradation. Pay attention to take the lens right and wrong way, Left, right right error) 。

note:. Don't use any tool to take the lens, such as tweezers.



2, the method of disassembling the lens must use professional tools manufacturer distribution, wipe out the lens method must be used to clean the mirror onto the palm, slight shake, lens on the lens paper, in order to avoid damage.

note: don't put the lenses in rough or hard surface, infrared lens is easy to scrape.





in the first place, with blowing the balloon's blow off of the surface of the original, especially the tiny particles at the surface of the flocculant and content of the lens, this step is necessary. But don't use the compressed air on the production line, because these would contain oil mist and water droplets in the air, it will deepen the pollution of the lens.



the second step application analysis of pure acetone to a slight cleaning lenses. This level of acetone is almost no water, it will reduce the possibility of a lens pollution.
cotton ball dipped in acetone must clean under light lens, and make a circular movement. Cotton swabs with a dirty but, must be replaced. Wash one time to avoid to produce wave. If there are two coating on the surface of the lens, such as lens, in this way, every face needs cleaning. First need to put a layer of clean with protective lens paper. ( If you can't remove dirt in this step, continue to step 3. )



the third step, if acetone cannot remove all the dirt, then use vinegar to clean. Vinegar when cleaning is the use of dissolution of dirt to remove dirt, but won't harm the optical lens. This kind of vinegar can be experimental level ( Diluted to 50% intensity) , or family containing 6% acetic acid with white vinegar. Cleaning procedures and acetone cleaning, and then use acetone to remove vinegar and dry lens, then to frequent in cotton ball to completely absorb acid and hydrate, until clean.



the fourth step, clean the lens of serious pollution (strongly Splash) For those who are jealous of the pollution of the lens, a polishing paste can be used to remove these pollutants. Pour the polishing paste shake, 4 - 5 drops to the cotton ball, polishing paste soon to scratch the surface. Frequently turn the lens, to avoid excessive polishing in one direction. Polishing time control within 30 seconds. Again a new wet cotton ball with distilled water, gently wipe to wash surface of the lens, wet the lens to the whole, as much as possible to remove the residues of polishing paste. Note that don't let the lens surface becomes dry, because it will be hard to remove the remaining polishing paste. Finally with propyl alcohol wet a fluff cotton swabs, gently clean the entire surface, remove residues of polishing paste and propyl alcohol as much as possible. Any time, found that the color change, immediately stop polishing, external membrane layer are corroded.



in the end, is in the sun, the surface of the self-study examination lens on black background. If it is found that there are polishing paste, and continue to clean according to the step. When through washing to remove pollutants and lens injury, especially caused by metal splash and dirt film burn out, to restore the good performance, the only way is to replace the lens.



in addition, the need to stress is that in the process of installation and cleaning lenses, any sticky, even nails seal oil, can make the lens absorption rate, reduce the service life. So, must adopt the following precautions:
1, don't use naked refers to install the lens. Should wear gloves or rubber gloves.
2, do not use sharp instrument so as not to cause the lens surface scrape.
3, shall not come into contact with the membrane layer when you pick up the lens, but took the edge of the lens.
4, the lens should be placed in dry and clean place to detect and clean. A good workbench surface should have several layers of clean paper towel, cotton paper and several cleaning lens.
5, the user should avoid talking over the lens, and let the food, beverage and other potential contaminants from the work environment.

optical lens is an integral part of laser cutting machine, in use process we also want to cherish and pay attention to maintenance, placed, testing, installation must be pay attention to avoid the lens damage and pollution. Is not only a holiday came back clean, work at ordinary times should also pay attention to. Cleaning regularly and accurately, so as to ensure the accuracy of optical lenses and normal use, prolong life.
