Stone engraving machine fault points, light path adjustment and maintenance

The fault points of stone engraving machine.

1, laser tube installation of the fulcrum should be reasonable, fulcrum should be in the laser tube length of the 1/4, otherwise it will cause the laser beam spot mode is bad, some work for a period of time to become a few points, the laser power can not meet the requirements, resulting in continuous change tube.

2., cooling system to ground, often clean the water tank and water, refrigeration temperature control water tank temperature control points should be reasonable, otherwise the result of laser tube is easy to be damaged and condensation power decline, tube water head loss, greatly shortened life expectancy, sometimes unable to work, resulting in continuous tube replacement.

3, water protection should always check the cleaning, cooling water often can not flush the water protection float switch or protect the water float switch is not reset, not the short connection method to solve the urgent needs. Cooling water quality is better, aluminum oxide of nozzle is too serious, the use of a period of time to regularly clean water pump and a water pipe, water protection in the dirt, or caused by laser tube burst or cold water head loss.

4, ceiling air device should be checked regularly clean up, the fan duct clean. Otherwise a lot of smoke and dust discharged out, serious quickly pollution lens and the laser tube, the mechanical and electronic components prone to oxidation caused by bad contact.

5, poly lens and mirror examination, work for a moment frames on the fever, rust discoloration of the lens surfaces; stripping cracking are belong to object to change, especially large air pump and air compressor for many customers, so the focusing lens will soon in water, so must time and check the lens (laser tube burring) of the optical system clean and of good quality.

6, the machine working environment can not be too bad, if the environment temperature is higher than 30 degrees, less than 18 degrees, the dust is too much, air pollution is serious, so that the machine is seriously damaged, the failure rate is rising; the wet environment of electrical accessories is easy to issue. So in this special remind customers to improve the working environment and the maintenance of the machine often.

7, power grid power to match. The power supply distribution and contact points of the whole equipment are good (fan, water cooler, laser, laser power supply, computer must be independent power supply).

8, laser tube work current to be reasonable, can not be a long time in the 90-100 intensity work; to rationalize the application of laser and laser energy; optical path system to clean correctly, otherwise the laser tube premature aging and rupture, so the laser machine working time should be adjusted in 50-60%, then according to material to adjust working speed, this is the best laser tube working condition.

9, the bottom plate and the material to be processed, or cause the focal length is not uniform some places do not wear, so that the intensity increase, it will lead to rapid aging of the laser tube.

11, laser power dissipation to open, otherwise a work current of 50% or more temperature rise is high, so that the failure rate of laser power increased. Like the TM series machine can cut off the power supply side, the heat emitted by the directly emitted.

Jiguang stone engraved chapter path regulating method

According to the customers now can't adjust light path of the situation, to help customers better regulation of light path and are now the engraved chapter machine method for adjusting light path and a simple introduction is as follows: purchase a picture disc explain)

The adjustment steps: (first determine the plotter parallel and shell)

(1), the thin double-sided adhesive 6 stacked together, put in the laser exit next to the first reflective mirror, mirror cover, attention must not make contact with the rubber to the surface of the mirror, in order to avoid the pollution of the mirror. Then press the test switch. Play observation laser light whether to play in the middle of the first mirror. If not, then we need to adjust the frame of screw and transferred to the laser shot spots so far in the center of the lens.

(2), the first reflector 6 double-sided adhesive layer on the second reflective mirror, first to the second reflector to push away from the nearest first mirror, press the test switch, make a point on the tape. Then the second mirror to push away from the first reflecting mirror at the far, press the test switch on the tape to play a little. To observe whether the coincidence of two, if not the first mirror adjustment of registration after the adjustment screw, to two points must coincide. (Note: the above two screws adjust the left and right side of the screw adjustment height.)

(3), push the third mirror (i.e., the laser light) to the second mirror, press the test switch, and then put the laser head to the farthest and nearest, observe whether the two points are re merged to adjust.

(4), take a look at the bottom of the laser head under the lens, take a layer of double-sided adhesive to the laser head of the lens hole, press the test switch. To observe whether the laser shot from the middle. If not for the corresponding adjustment, namely from the first mirror and laser began to adjust, after adjusting the lens is installed.

The three mirrors are above the engraving machine, and the four mirror is so and so on.

 

Maintenance of stone engraving machine.

Laser engraving machine in the general power output of the laser, all of the lenses are mostly due to the cause of manufacturing process or by external pollution and other factors to cause the lens to absorb a large specific laser wavelength, as time passes so that the lens shortened, due to the damage caused by the lens and even stop when the situation occurs.

The increase of laser wavelength absorption caused by the lens can cause the reflection of the lens, the refractive index changes, and the laser wavelength is high, which makes the lens center temperature high and the edge temperature is low.

In the use of engraved chapter machine, due to pollution caused by high absorption of lens heat lens effect will produce many problems. The irreversible thermal stress of the lens substrate, the power loss caused by the beam propagation through the lens, the partial movement of the focusing point of light, and the premature damage of the coating layer can cause the lens to be destroyed. For exposure to the air in the lens, we do cleaning, often do not follow the requirements of the lens cleaning and attention matters, literally drawn, the results will cause new pollution and even scratch the lens, causing irreparable damage. So according to many years of experience, it is concluded that no matter which kind of optical lens is the most important, to have a good cleaning habits to carefully clean the lens, you can reduce or eliminate the man-made causes of pollution. Such as fingerprints and spit flowers etc..

As a common sense, when used in military operation of optical system, whether cleaning, disassembly, installation with a finger or medical gloves, to keep follow lens cleaning requirements and matters needing attention, in the cleaning process, only with specified materials, such as optical lens cleaning paper, cotton swab, reagent grade ethanol. Cleaning, removing and installing the lens for any lens will cause the life of the lens to be shortened, or even permanently damaged. So, we need to use common sense to prevent the lens from other causes of pollution, such as the case of moisture, smoke, dust, etc.. In determining the pollution of a lens, we want to use the washing ear ball lens, until the surface no particles is better, do not use the mouth to blow. Because most of the air blowing air, water, etc. will further pollute the lens. If after washing ear ball handling its surface is still contaminated, we must use a special cotton swab dipped in laboratory grade acetone, ethanol to gently wipe. So you can remove most of the pollution thin layer. The pollution of the lens of the laser will cause serious errors in the laser output and data acquisition system. If we can keep the lens clean, it will be extended to the service life of the machine.
