What are the cleaning methods for different lenses of laser welding machines? To put it simply, a laser lens is a lens installed on a laser tube, which is used to focus and focus the laser. Divided into focusing mirrors and reflecting mirrors. Laser welding machine is a new welding method, mainly for the welding of thin-walled materials and fine parts, and can complete spot welding, butt welding, stack welding, seal welding, etc. , high aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need for post-welding treatment or simple treatment, high weld quality, no pores, accurate control, concentrated light spots Small, high positioning accuracy, easy to automate.

1. Clean the focusing lens: When disassembling and assembling, be careful not to use excessive force or collide with hard objects. When the equipment is running, ensure that the air pressure is sufficient. The cleaning principle of focusing lenses is to try not to clean them without contamination. If there is contamination, it should be cleaned in time. When cleaning the lens, choose a soft cotton ball made of laboratory-grade paper, dip it in an appropriate amount of acetone or high-purity alcohol, gently rotate it clockwise from the center of the lens, and rub it to the edge. When necessary, both sides of the lens need to be cleaned and wiped carefully.

2. Clean the reflective lens: Remove the lens from the frame; put the lens paper on the mirror surface with the mirror surface facing up; put a few drops of acetone on the lens paper, gently pull the lens paper to lift the mirror surface; repeat the above process until the mirror surface Clean the mirror surface without dirt or residual stains; then place the lens into the lens holder. If you choose a molybdenum mirror as a reflector, it can be used directly after polishing, and the mirror surface can be cleaned with water (soapy water or water containing detergent). However, other coated lenses cannot be washed with water because many coatings dissolve in water and the lenses will be damaged.

3. Lens cleaning: Bend the lens paper into several folds and soak it with a few drops of analytical pure acetone; gently wipe the lens surface with wet lens paper, being careful not to press the lens with your fingers; repeat several times until the lens surface is clean and free of dirt and Blow dry with dry air; if necessary, wet lens paper with a few drops of acetone, roll it into a rod, and gently wipe the surface of the lens to remove heavy dirt drops. It should be noted that acetone can easily absorb moisture from the air and contaminate the acetone itself, so cover the acetone bottle and do not pour the remaining acetone liquid after cleaning back into a new acetone bottle.
