What is the laser engraving machine lens?

The laser engraving machine lens is divided into a reflective lens and a focusing lens, which are used to focus and reflect the laser.

How to adjust the laser engraving machine lens?

The first step: adjust the laser current of the engraving machine to less than 5, so that the laser power is not too strong;

Step 2: Put the dimming paper in front of the first lens, and gently press the test switch by hand (lightly press and release immediately, you can see the spotted laser spot on the dimming paper), and see if the spot falls. On the first lens (preferably in the middle), if the lens can be found, this step is completed. If you can't hit the lens or it is deflected, you need to adjust the position or height of the laser tube to meet the above criteria.

The third step: the optical path adjustment between the first lens and the second lens. First place the laser paper in front of the second lens, push the guide to the position (a) in the figure and click a test switch to see the position of the spot. Next, pull the guide to the position (b) and click the test switch to see if the positions of the two spots coincide. If it is coincident and the spot position is inside the lens, the optical path between the lenses 1 and 2 is correct; if it is not coincident, it needs to be adjusted by adjusting the adjusting screw on the frame behind the lens 1, and the two points are adjusted together.

The fourth step: the adjustment of the optical path between the lenses 2 and 3. First push the laser head to the position (c) in the figure, and put the dimming in front of the small hole of the laser head / press the test switch to look at the light shift, then push the head to the position (d) and press it again. Test the switch to see if the two marks overlap. If the two spots are in the small hole of the laser head, the light path is correct. If it is not the same point, you need to adjust the adjusting screw behind the frame 2 to adjust. The above criteria. Note: The principle of optical path adjustment between lenses 1, 2 and 2, 3 is the same.

The fifth step: the optical path adjustment between the lenses 3 and 4 (one step in the key) first remove the lens, put the glossy paper under the laser head and click the test switch to see if the spot is below the dimming paper. in the middle. If it is exactly the middle, the optical path is positive; if the spot is right, the laser tube is too low; if the spot is left, the laser tube is too high; in both cases, it is necessary to adjust the height of the laser tube to solve. If the spot is inside or outside, you need to adjust the optical path by moving the position of the laser head (there are three screws on the laser head, through which the inside and outside of the laser head can be adjusted).

Step 6: Mount the lens and the adjustment of the light path is completed.

How to adjust the laser engraving machine lens?

The principle of reflection of light, etc., the first time the debugger must follow the instructions, and consult the technical staff if necessary. In addition, the laser has a certain degree of burnability and is invisible, so be sure to pay attention to safety when dimming the road.

How to adjust the laser engraving machine lens?

The only purpose of cleaning the laser engraving machine lens is to remove the contaminants from the lens and not to cause further contamination and damage to the lens. In order to achieve this goal, people should often adopt a relatively low risk approach.

How to clean the laser engraving machine lens?

This step is necessary by first applying an air ball to blow off the float on the surface of the component, especially the lens with tiny particles and flocs on the surface. But don't use compressed air on the production line because it contains oil and water droplets, which will deepen the pollution of the lens.

The second step is to apply a slight cleaning of the lens with acetone (or alcohol, preferably acetone). This grade of acetone is almost anhydrous, which reduces the likelihood of lens contamination.

The acetone on the cotton ball must be cleaned under illumination and circularly moved. Once the cotton swab is dirty, it must be replaced. Cleaning should be done at one time to avoid creating ribs.

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 lens paper for protection.

If acetone does not remove all the dirt, then use acid vinegar to clean. Sour vinegar cleaning uses the dissolution of dirt to achieve the removal of dirt, but does not cause damage to the optical lens. This acid vinegar can be experimental grade (diluted to 50% strength), or 6% acetic acid white vinegar for household use. The cleaning procedure is the same as for acetone cleaning, then acetone is used to remove the vinegar and dry the lens. At this time, the cotton balls are frequently changed to completely absorb the acid and hydrate.

What are the advantages of laser engraving machine lenses for proper cleaning?

When the lens is properly cleaned and operated, its service life and performance will undoubtedly improve significantly. Taking some of the precautions and maintenance measures in this article will ensure that the laser engraving machine will work longer and perform better.

What are the precautions for using laser engraving machine lenses?

1. Never use a bare finger to install the lens. Wear a finger or rubber glove.

2. Do not use sharp instruments to avoid scratching the surface of the lens.

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

4, the lens should be placed in a dry, clean place to detect and clean, there should be several layers of cleaning paper towels or paper wipes, and there are several cleaning lens tissue paper.

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