1. Precautions for the use of lenses
Do not touch the optical surfaces such as focusing lens, protective lens, QBH head, etc. directly with your hands to prevent scratches or corrosion of the mirror surface. If there is oil 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 cause the surface of the lens to age. 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.
2. 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 light and clean white gloves; it is strictly forbidden to touch the lens with any part of your hand; when removing the lens Take it from the side of the lens and do not directly touch 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 pieces of lens professional paper underneath. When taking the lens, you should be careful to prevent bruises and falls, and you are not allowed to apply any force on the coating surface of the lens; the lens holder where the lens is installed should be cleaned, and a clean air spray gun should be used to clean the dust and dirt in the lens holder. Then, gently put the lens into 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, thereby affecting the quality of the beam.
3. Steps to clean the lens
Different lens cleaning methods are different. When the mirror surface is flat and there is no lens holder, use lens paper to clean; when the mirror surface is curved or the mirror surface has a lens holder, clean it with a cotton swab. The 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 surface of the lens; Use alcohol or lens paper to clean the surface of the lens. The clean side of the lens paper should be placed on the surface of the lens and dripped. 2~3 drops of high-purity alcohol or acetone, slowly pull out the lens paper horizontally toward the operator, repeat the above actions several times until the lens surface is clean, do not apply pressure on the lens paper to prevent scratches, such as The mirror surface is very dirty. You can fold the lens paper 2 to 3 times and repeat the above steps until the mirror surface is clean. It is forbidden to drag dry lens paper 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 cotton swab moistened with high-purity alcohol or acetone to move in a circular motion from the center of the lens , Scrub the lens, change another clean cotton swab every week after wiping, repeat the above operation until the lens is clean; observe the cleaned lens until there is no dirt or spot on the surface of the lens; take the cleaned lens according to the above In the method described above, place the lens on the lens holder. It is forbidden to use used cotton swabs for operation.
If there are debris that is not easy to remove on the surface of the lens, you can blow the surface of the lens with rubber air. Clean the front and back sides. After cleaning, reconfirm that there are no residues of the following: detergent, absorbent cotton, foreign matter, and impurities. The cleaned lens should not be exposed to the air. Install it as soon as possible or temporarily store it in a clean sealed container.
4. Storage of optical lens
The optical lens is stored properly 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 easily damaged by condensation and frost when taken out; the storage environment temperature should not be higher than 30℃, otherwise it will affect the coating of 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, thereby affecting the performance of the lens.
5. Replacement of vulnerable parts
The nozzle at the lower end of the cutting head is under the worst conditions and is easily damaged. You can turn it counterclockwise to unscrew and replace it with a new one. After replacement, you must unscrew the nozzle and perform a new capacitor calibration. When replacing the new ceramic body and assembling, you must align the two positioning posts with the positioning hole of the induction seat, and then tighten the pressure ring after the ceramic body is leveled and straightened by hand. After the ceramic body is compressed, the nozzle is tightened. Failure to meet the above installation requirements may damage the sensor base module parts and cause the system to fail to work normally.
