The use of laser marking machine and how to maintain and maintain it

How to use a portable laser marking machine Although the equipment of the laser marking machine is larger than the traditional equipment, in terms of operating costs, the use of the laser marking machine is much lower. The absorption of the laser marking machine increases with the temperature index Rise and increase, above the unavoidable temperature, the substrate does not consume energy to dissipate the heat it absorbs, the temperature rises, causing the absorption to increase further, and causing a further increase in temperature, so a vicious circle, leading to excessive thermal stress and cracking, The reason for the hint is that the absorption coefficient of the three kinds of information, depending on the temperature, their damage temperature is 70 degrees Celsius, 250 degrees Celsius and 300 degrees Celsius, the ability to withstand heat damage is poor, but it is cheaper, so the thermal distortion is high The common problems in the power laser intake system are only applicable to the carbon dioxide laser system with 100w power, the laser is composed, the laser marking machine is used as a telescope, and the optical path is reversed. Why, where is the reason, thermal deformation is a high-power laser The injection system, it is also the role that the laser marking machine can produce, this is its power, your laser cutting beach needs water to meet the condition that the strength of the river is not very high, generally choose the lens of the photo, the laser marking machine double Spherical reflection grave concentrating county double spherical reflection polygonal light as shown in the figure, it is composed of a convex mirror curvature radius r and one or four mirror curvature radii, the curvature of the two spheres is severe, and the radius ratio of the radii About parallel incident light, the system has no difference in line tertiary balls, and no difference in dispersion in printing. The absorption coefficient of the laser marking machine matrix material to the laser is significantly different, and the absorption coefficient of the laser marking machine is 7 times that of the laser marking machine. The size of part of the light energy, and the matrix absorption and surface absorption and the total light energy absorbed by the two parts are all dissipated through the heat conduction of the matrix. In terms of thermal conductivity, the thermal conductivity is much better. The thermal conductivity is 2.7 times. Which material makes the lens with the higher quality factor of thermal distortion, and the thermal distortion is small? It depends on whether the lens absorbs the laser light mainly from the surface or from the matrix. When the lens absorbs light from the surface When absorption is dominant, the strong absorption of the matrix is ​​not the main heat source, but its high thermal conductivity plays a major role, accelerating heat dissipation, reducing temperature rise, and small thermal distortion. On the contrary, when the absorption of laser by the lens is dominated by matrix absorption, It plays a major role in the small absorption coefficient of the laser, and its thermal distortion quality factor is high. The use of laser processing can ensure the original precision of the workpiece and has wide adaptability to materials. Various metals and some non-metals can make very fine marks on the surface of materials with very good durability.

1. For the overall condition of the equipment, whether the lubrication is normal, whether the mobile phone or strong magnetic objects are close to the vibrating mirror, the current of the laser marking machine should not exceed 20A, and the lens should not be touched with hands or other objects, and whether there is any abnormal noise during the operation of the equipment. 2. Lens cleaning: There are 3 mirrors and 1 focusing mirror on the engraving machine (the No. 1 mirror is located at the emission exit of the laser tube, the No. 2 mirror is located at the left end of the beam, and the No. 3 mirror is located at the fixed part of the laser head. At the top, it is emitted from the laser head after focusing. The lens is easily stained with dust or other pollutants, resulting in loss of laser or damage to the lens. No. 1 and 2 lenses do not need to be removed when cleaning. First, sprinkle the cleaning solution on the cloth, then start from the middle, and rotate outward until it is clean. The No. 3 lens and focusing lens need to be taken out of the frame and wiped in the same way. After wiping, put them back as they are. Cleaning: Clean once a week and replace the water inside the IC automatic laser marking machine. The circulating water inside is not good for the machine if it is too long. The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water. And control the water temperature below 35°C. 3. Regularly clean the F-θFor the protective glass of the lens, wipe it in one direction with a clean cloth dipped in a small amount of alcohol every day.

4. Regularly check the operation status of the fans, and replace the fans that are not operating normally. 5. Regularly clean the mouse and keyboard. 6. Regularly clean the laser fan and air duct dust. When the equipment is powered off, use an air gun to clean along the air duct every week.

7. Before starting the machine every day, carefully check the pressure of the auxiliary gas. If the gas pressure is not enough, check whether there is any leakage in the pipeline. 8. Check whether the buttons are damaged, and check whether the indicator lights are normal. 9. Before processing, check whether the lens of the focusing mirror is stained or not.

10. Before processing, check whether the position of the lifting mechanism is offset. 11. Before processing, check whether the software parameter settings have changed. 12. After the daily work is completed, shut down according to the shutdown procedure, and then turn off the main power supply.

13. After the work is completed, clean up the processing waste in time, clean up the work site, and keep the work site neat and clean.
