How to clean and maintain laser lenses

In the optical path system of the laser cutting machine, the protective lens is consumable, so in order to reduce the use cost as much as possible, the lens should be cleaned in strict accordance with the specifications.

In the process of cleaning and replacement, pay attention to the placement, detection and installation of protective lenses to avoid lens pollution or damage as far as possible.

After the installation of new lenses, the protective lenses shall be inspected regularly and cleaned in time.

How to clean and maintain laser lenses

Lens cleaning

For lens cleaning, different cleaning methods can be adopted according to the pollution level, as follows:

(1) Flexible cleaning for lenses with slight pollution (dust, fiber particles);

Use a blowing airbag or clean air to blow off the pollutants scattered on the lens surface;

Note: avoid using air pipes in the workshop because they usually contain a lot of oil and water. These pollutants will form a harmful absorption layer on the lens surface.

(2) Flexible cleaning for lenses with slight pollution (stains and fingerprints);

Soak an unused special cotton swab with a detergent such as acetone or absolute ethanol, gently wipe the lens surface (do not rub hard), and slowly drag the wet cotton on the lens surface so that the liquid left behind the wet cotton can evaporate immediately so that no trace will be left;

Note: only pure paper cotton swabs (Q-tip brand cotton swabs are recommended) or polyester fiber cotton swabs can be used. Reagent grade acetone and absolute ethanol are recommended for cleaning agents.

(3) Medium intensity cleaning for lenses with moderate contamination (saliva, oil);

Soak an unused cotton swab with 6% distilled white vinegar, wipe the lens surface with slight pressure, wipe the excess distilled vinegar on the lens surface with a clean dry cotton swab, and then soak a cotton swab with acetone to gently wipe the lens surface to remove all acetic acid;

In addition, for seriously polluted or dirty lenses, optical polishing fluid can also be used to remove pollutants on the lens surface. The steps are as follows:

(1) Before using it, shake the polishing liquid container fully, pour out four to five drops of polishing liquid and drop it on the cotton ball.

On the surface of the lens to be cleaned, use the weight of the cotton ball to gently move the cotton ball in a round way (do not press the cotton ball).

Please rotate the lens constantly to avoid excessive polishing in one direction. The time taken to clean the lens should not exceed half a minute. If the color of the lens surface changes in this step, it indicates that the outside of the lens film has been corroded, and the cleaning shall be stopped immediately;

(2) After using the polishing solution, soak an unused cotton swab with distilled water, then gently wipe the lens surface with it, thoroughly wet the lens surface, and remove the residue of the polishing solution as much as possible.

Do not make the lens surface dry, which will increase the difficulty of removing polishing fluid residue;

(3) Quickly wet a pile cotton swab with absolute ethanol, and then use it to gently and thoroughly clean the lens surface.

Cover the whole surface with the head of a cotton swab and remove as much polishing fluid residue as possible;

(4) Wet the pile cotton swab with acetone and clean the lens surface with it to remove all anhydrous ethanol and polishing fluid residues left during the cleaning process.

When performing the final cleaning with acetone, please gently drag the cotton swab on the lens surface to wipe off the original traces until the whole surface is wiped clean.

Make the last wiping action with a cotton swab and move it slowly to ensure that the surface behind the cotton swab can dry immediately, which can eliminate the streaks on the surface. Some types of contamination or damage (such as metal spatter, potholes, etc.) cannot be removed.

If the lens surface has the above pollution or damage and cannot be cleaned and restored, the cleaning shall be abandoned and replaced with a new lens to ensure the cutting quality.

Lens maintenance

The following measures can be taken for daily maintenance:

(1) Before removing the protective lens, ensure that the window around the protective lens of the cutting head is clean, and no fan is allowed to blow in the direction of the cutting head, so as not to bring dust into the cutting head and cause internal pollution when removing the protective lens;

(2) Do not install the lens with bare fingers, but wear powder-free finger covers or rubber/latex gloves;

(3) Do not touch the film and mirror when taking the lens. Hold the edge of the lens and place the lens on the lens wiping paper;

(4) Avoid speaking above the lens and keep all pollutants away from the working environment as far as possible;

(5) When cleaning the lens, try to operate in a dust-free environment (absolute ethanol and other cleaning agents will only dissolve dirt and will not cause lens damage).

How to do the antifreeze maintenance of laser equipment in winter

antifreeze maintenance of laser equipment in winter

The temperature in winter will cause the temperature of the laser and water cooler to be too low, which may cause the pipeline of the water cooler to freeze.

Because the density of ice is less than that of water, the cooling water pipeline will be broken or deformed due to volume expansion inside the water cooler and laser, resulting in significant damage to relevant core components.

Therefore, it is very necessary for enterprises to do a good job in anti-freezing maintenance of laser equipment in winter.

Trick 1: pay attention to drainage

If the water cooler and laser are not used for a long time, it is necessary to check the drainage condition of the equipment to ensure that the water in the water tank, pipeline, water pump and other parts of the water cooler is completely discharged to prevent freezing.

The drainage method is as follows:

(1) Water tank drainage method: open the drainage valve at the lower part of the water tank to drain the water in the water tank. If necessary, tilt the water cooler to a certain angle to make the drainage outlet the lowest point.

(2) Drainage in the pipeline: open the water pipe interface and blow air from the inlet and outlet of low-temperature water and high-temperature water with compressed air until the residual water of the water cooler is blown out. (The pipeline structure shall be subject to the actual situation)

(3) Open the water tank cover and observe whether there is residual water in the water tank. If so, tilt the water cooler slightly to drain the water or suck the water dry with a dry towel.

(4) Drainage of water pump head: there is a drain screw at the lower part of each water pump head. When the water cooler needs to be shut down or transported for a long time, open the drain screw of the pump head to drain the water in the water pump (preferably blow it out with compressed air), and finally tighten the drain screw.

Trick 2: the water cooler does not stop

For the laser equipment in working state, try to ensure that the ambient temperature of the laser is higher than 5℃, so as to meet the normal use conditions of the machine.

If the ambient temperature of the equipment cannot be guaranteed to be higher than 5 ℃, please also ensure that the laser water tank is always in operation.

The constant temperature system of the water tank can keep the laser waterway system at the set temperature of the water tank. (Note: in case of power failure, it shall be found in time)

Trick 3: selection of antifreeze

Fill the water tank with Antifrogen N(ethylene glycol) antifreeze in the proportion of 3:7 (3 is antifreeze and 7 is water).

After adding antifreeze, it can resist the temperature of – 20 ℃ without freezing. (Since the antifreeze is corrosive to a certain extent, please clean the whole water circuit and replace it with normal cooling water after winter)
