The laser lens is an important accessory of the laser welding machine. In order to ensure the laser welding quality, the laser lens needs to be cleaned regularly. Of course, there are different cleaning methods for different types of laser lenses. Today, we have a brief understanding of several lens cleaning methods of the optical fiber laser welding machine.
Cleaning the lens of the optical fiber laser welding machine: bend the lens wiping paper into several folds and soak it with a few drops of dissecting pure acetone; Wipe the lens surface quietly with soaked lens paper, and be careful not to press the lens with your fingers; Repeat several times until the appearance of the lens is clean and there is no dust and residue left on the mirror surface; Dry with dry air; The lens paper wetted with a few drops of acetone can be rolled into a rod, and the lens surface can be quietly wiped to remove heavy stains. It should be noted that acetone is easy to absorb moisture and water from the air and pollute itself, so the acetone bottle should be tightly covered, and the residual acetone liquid after cleaning should not be poured back into the new acetone bottle.
Cleaning of reflector lens of optical fiber laser welding machine: remove the lens from the lens frame; Put the lens paper on the mirror with the mirror facing up; Drop a few drops of acetone on the lens paper, and gently pull the lens paper over the mirror surface; Repeat the above process until the mirror is clean and free of dirt and residue; Install the lens into the mirror base. If molybdenum mirror is selected as reflector, it can be directly used after polishing because it cannot be coated, so it can be cleaned with water (soap water or water containing detergent). However, other coated lenses of the laser welding machine cannot be cleaned with water. Because many coatings are dissolved in water, the lenses will be damaged.
Cleaning of gathering lens of optical fiber laser welding machine: During disassembly, be careful not to use too much force or collide with hard objects During equipment operation, ensure that there is sufficient air pressure. The cleaning principle of collecting lenses is that they should not be cleaned when there is no pollution, and they should be cleaned in time if there is pollution. When cleaning lenses, laboratory grade paper soft cotton balls should be selected, dipped with an appropriate amount of acetone or high-purity alcohol, and quietly rotated clockwise from the center of the lens to the edge. Both sides of the lens need to be cleaned, so you should be careful when wiping.
The above are the cleaning precautions for several different lenses of the optical fiber laser welding machine. The laser beam of the optical fiber laser welding machine is transmitted through the lens. Therefore, in order to ensure the high-quality welding effect. Our daily cleaning of laser lenses is indispensable.
