How to remove oil from the lens of a laser cutting machine

1. In the process of replacement, attention should be paid to the placement, detection and installation of optical lenses to prevent the lenses from damage and pollution. Once a new lens is installed, it should be cleaned regularly.

2. When the laser cuts the material, a large amount of gas and splash will be released on the working surface, which will cause damage to the lens.

3. When contaminants fall on the surface of the lens, they will absorb energy from the laser beam, resulting in a thermal lensing effect. If the lenses have not yet developed thermal stress, they can be removed and cleaned by the operator.

4. During the installation and cleaning of the lens, any bit of sticky, even the nail marks of oil droplets, will improve the absorption rate of the lens and reduce the service life. Therefore, the following precautions must be taken:

1) Never use your bare finger to install the lens. Finger gloves or rubber gloves should be worn.

2) Do not use sharp instruments to avoid scratches on the surface of the lens.

3) When taking the lens, do not touch the film, but hold the edge of the lens.

4) The lenses should be placed in a dry and tidy place for inspection and cleaning. A good workbench should have several layers of cleaning paper towels on the surface and several sheets of cleaning lens tissue.

Users should avoid talking above the lenses and keep food, beverages, and other potential contaminants away from the work environment.

Lenses should be cleaned in a relatively low-risk manner. The following procedure is designed for this purpose and should be used by the user. It is necessary to blow off the floats on the surface of the original with a balloon blow, especially the lenses with tiny particles and flocculent on the surface.

However, do not use compressed air on the production line, as this air can contain oil mist and water droplets, which can further contaminate the lenses.

In the second step, the lens is lightly cleaned with pure acetone. This level of acetone is virtually anhydrous, which reduces the potential for lens contamination.

Cotton balls dipped in acetone must be cleaned under light and moved in a circular motion. Once the swab is dirty, it must be replaced. Cleaning should be done in one go to avoid corrugation.

If the lens has two coated surfaces, such as lenses, each side needs to be cleaned in this way. The first side needs to be placed on a clean layer of lens paper for protection.

If acetone does not remove all the dirt, then use sour vinegar to clean. Sour vinegar is used to remove dirt by dissolving dirt, but it will not cause damage to the optical lens. This sour vinegar can be experimental (diluted to 50% strength) or white vinegar with 6% acetic acid for home use.

The cleaning procedure is the same as acetone cleaning, followed by acetone to remove the acid vinegar and dry the lenses, at which point the cotton balls should be changed frequently to completely absorb the acid and hydrates. Until cleaned.

When contaminants and lens damage cannot be removed by cleaning, especially when the coating burns out due to metal splashes and dirt, the only way to restore good performance is to replace the lenses.

1.The protective lens material is ZNSE (zinc arsenide), so it is brittle and afraid of falling; When disassembling, you must pay attention: do not use too much force, do not collide with hard objects.

2.When cleaning your laser cutter to protect your lenses, be sure to use a clean rag and optical-grade solvent to prevent damage from other contaminants.

3.Due to the relatively small size of most contaminants and surface defects, magnifying equipment is often required when inspecting lenses.

Instead, you can use gloves and special equipment. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers.

4.Whatever method is used to clamp the fiber laser cutter to protect the lens, it should only be clamped along a non-smooth surface, such as the matte edge of the lens edge.

5.The wipe must be moistened with a suitable solvent, not dried. Considering the softness, the available wipes are cotton wipes or coated paper, such as cotton balls, lens paper, cotton swabs, etc.

6.In addition to amplifying equipment, it is sometimes necessary to illuminate optical surfaces with brighter beams to enhance the specular reflection of surface contaminants and defects so that they can be found more easily.

1. Replace the circulating water and clean the water tank: Make sure the laser tube is filled with circulating water before the machine works. The quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, it is necessary to change the circulating water regularly and clean the tank regularly. It's best to do it once a week.

2. Fan cleaning: The long-term use of the fan of this machine will cause the fan to accumulate a large amount of solid dust, which will make the fan produce a lot of noise, which is not conducive to smoke exhaust and deodorization. When the suction power of the fan is insufficient and the exhaust is not smooth, the fan should be cleaned.

3. Lens cleaning: There will be some mirrors and focusing lenses on the machine. The laser light is reflected and focused through these lenses, which are then emitted from the laser hair.

Lenses are susceptible to dust or other contaminants, causing laser loss or lens damage. So wash the lenses every day.

1. Cleaning of the whole machine.

Air Compression Cleaning Method:

Run the laser cutting air compressor for a few minutes until the oil reaches normal temperature; Turn off the laser cutting air compressor, when the internal working pressure is exhausted, open the oil filler cap, pour in the laser cutting air compressor system cleaning agent, and tighten the oil filler cap;

Turn on the laser cutting air compressor for 30 minutes; Drain the old oil and add new oil. Generally, the working temperature of the laser cutting air compressor will drop by about 10 degrees after cleaning.

2. Cooler cleaning.

In China, laser cutting air compressor coolers are generally divided into air-cooled and water-cooled, so different coolers have different cleaning methods.

Air-cooled cooler.

Open the hood to clean the hood, or remove the cooling fan;

Blow off the dust with compressed air and remove the dust from the air hood; If dirty, spray some degreaser before blowing.

When the screw laser cutting air compressor cannot be cleaned by the above method, the cooler must be removed, soaked or sprayed with cleaning solution, and cleaned with a brush (it is strictly forbidden to use a wire brush). Install the cover or cooling fan.

Water-cooled cooler.

Unpack the cooling water inlet and outlet pipes. Inject the cleaning solution to soak or rinse with a pump (backwashing effect is good).

Rinse with clean water and install cooling water inlet and outlet pipes. When the fouling of the oil cooler is serious, it is not ideal to clean it with the above method. You can detach the oil cooler, open the caps at both ends, and remove limescale with a special cleaning brush or other tool.

When the medium side of the cleaning cooler cannot be effectively cooled. The screw laser cutting air compressor needs to clean the oil side as follows:

Dismantle the inlet and outlet pipes;

Immerse in the cleaning solution or rinse with a pump circulation (backwashing is better);

Rinse with clean water;

Dry with dry air or dehydrate with natural dehydrated oil;

Install the inlet and outlet pipes.

The maintenance and maintenance of the laser cutting machine are as follows:

1. The cooling system should be grounded, the water tank and waterway should be cleaned frequently, and the temperature control point of the refrigeration temperature control water tank should be appropriate, otherwise the laser tube will be damaged and condensation, and the power will decrease. The cold water head falls off, the life is greatly shortened, and sometimes it cannot work, resulting in constant pipe changes.

2. The fulcrum of the laser tube installation of the laser cutting machine should be reasonable, and the fulcrum should be at 1 4 places of the total length of the laser tube, otherwise the laser tube spot mode will deteriorate, and sometimes the spot will become several points in a period of time, resulting in the laser power decline and cannot meet the requirements.

3. Water protection should be checked and cleaned frequently, and the cooling water often cannot be flushed with the water protection float switch or the water protection float switch is not reset, and the problem cannot be solved by short-circuit method.

4. The suction device should be checked and cleaned on schedule, and the fan duct should be cleaned. Otherwise, a lot of smoke and dust cannot be discharged, which will quickly pollute the lens and laser tube, so that the mechanical and electronic parts are easily oxidized and cause poor contact.

5. The focusing lens and reflector are inspected, and the frame will heat up after working for a while, and the surface of the lens will be discolored and rusty; Peeling and cracking are the objects to be replaced, especially for many customers with air pumps and air compressors, which cause water accumulation on the focusing lens, so it is necessary to regularly ensure the cleanliness and quality of the lens in the optical path system.

6. The working environment of the laser cutting machine should not be too bad, if the ambient temperature is higher than 30 degrees and lower than 18 degrees, there is too much dust and serious air pollution, so that the machine will be damaged and the failure rate will continue to rise; In a humid environment, it is easy to have problems with electrical accessories.

Directions for use:

1. Dip a cotton swab in the cleaning agent first.

2. Wipe evenly on the mirror surface.

3. Wait for the cleaning agent to evaporate and dry before working.

4. It is harmless to the human body and does not need to take protective measures (except for sensitive**).

5. This product is highly volatile, flammable, volatile and dry within 1 to 3 seconds, without any residual substances, so it has no effect on lenses, optical glass, liquid crystal glass and its frame, coating, paint layer and other materials.

6. Shake it before use, the effect is better (because it is a compound cleaning agent, it is normal to have a little precipitation).
