How to Maintain the Protective Lens of Fiber Laser Cutting Machine

The lens of the protective laser cutting machine is located in the lower part of the centering module, which is susceptible to smoke and dust. It is recommended to clean it once every day. First completely loosen the screws of the protective mirror drawer, pinch the two sides of the protective mirror box drawer with your thumb and index finger, slowly pull out the protective mirror box drawer, being careful not to lose the sealing rings on the upper and lower sides of the drawer, and then seal the drawer opening with adhesive tape. Prevent dust from contaminating the focusing lens. The protective lens is a flat lens, and the sealing ring and the protective lens are released by pressing the lens. When installing the lens, place the lens first, and then press the sealing ring. The collimator lens and the focusing lens are located inside the fiber cutting head. Record the sequence of disassembly when disassembling, and ensure the accuracy of reinstallation.

Precautions for the use of lenses

Do not touch the focusing lens, protective lens, QBH head and other optical surfaces directly with your hands to prevent scratches or corrosion of the lens. If there is oil stains or dust on the lens surface, it will seriously affect the use of the lens, and the lens should be cleaned in time. It is strictly forbidden to clean the surface of the optical lens with water or detergent. The surface of the lens is coated with a special film. If you use these to clean the lens, it will damage the surface of the lens. Do not place the lens in a dark and humid place, as this will age the lens surface. When installing or replacing the reflector, focusing lens and protective lens, do not use too much pressure, otherwise it may cause the deformation of the lens and affect the quality of the beam.

How to install or replace optical lens

Be careful before installing or replacing optical lenses, wear clean clothes, clean your hands with soap or detergent, and wear

Wear light and clean white gloves; it is strictly forbidden to touch the lens with any part of the hand; when taking the lens, take it from the side of the lens.

Touch directly on the coating surface of the lens.

When assembling the lens, do not blow into the lens with your mouth; the lens should be placed steadily on a clean table with a few sheets underneath

Lens professional paper. When taking the lens, you should be as careful as possible to prevent bumps and falls, and it is not allowed to apply any

Power; the lens holder where the lens is installed should be clean, use a clean air spray gun to clean the dust and dirt in the lens holder, and then, the lens

The piece is gently placed in the lens holder.

When the lens is installed on the lens holder, do not use too much force to fix the lens, so as not to deform the lens and affect the quality of the beam.

the amount.

Steps to clean the lens

Different lens cleaning methods are different. When the mirror is flat and there is no lens holder, use lens paper to clean;

When it is a curved or mirrored surface with a lens holder, use a cotton swab to clean it. Specific steps are as follows:

Steps to clean the lens with lens paper: use a clean air spray gun to blow off the dust on the lens surface; use alcohol or lens paper

To clean the surface of the lens, place the clean side of the lens paper flat on the surface of the lens, add 2 to 3 drops of high-purity alcohol or acetone, slowly pull out the lens paper horizontally toward the operator, and repeat the above actions several times Until the lens surface is clean, it is forbidden to apply pressure on the lens paper to prevent scratches. If the lens surface is very dirty, fold the lens paper in half 2 to 3 times and repeat the above steps until the lens surface is clean. Do not use dry lens paper to drag directly on the mirror surface.

Steps to clean the lens with a cotton swab: first use a spray gun to blow off the dust on the mirror surface; then use a clean cotton swab to remove the dirt; use a new

A cotton swab dipped in high-purity alcohol or acetone moves in a circular motion from the center of the lens to scrub the lens. After each week, replace it with another

A clean cotton swab, repeat the above operation until the lens is clean; observe the cleaned lens until there is no dirt on the surface of the lens

Or spots; put the cleaned lens on the lens holder according to the method described above. Prohibited to use used

The cotton swab to operate.

If there are debris that is not easy to remove on the surface of the lens, rubber air can be used to blow the surface of the lens. Clean both sides, clean

After cleaning, reconfirm that there are no residues of the following: detergent, absorbent cotton, foreign matter, impurities. The cleaned lens cannot be exposed to

In the air, install as soon as possible or use a clean sealed container for temporary storage.

Storage of optical lenses

The optical lens is properly stored to keep the quality of the lens intact. The storage environment temperature is 10～30℃. Do not put the lens in a freezer or similar environment, otherwise the lens will be condensed and frosted when taken out, which will damage the lens;

30℃, otherwise it will affect the coating on the lens surface. Keep the lens in the box, the lens should be placed in a vibration-free environment, otherwise it will easily cause the lens to deform, which will affect the performance of the lens.

The installation requirements mentioned above may damage the sensor base module parts and cause the system to fail to work normally.
