What safety precautions should be paid attention to when operating the UV laser marking machine? The UV laser marking machine uses a solid-state laser as the laser source; scans through a high-speed galvanometer; . The high-speed control software sends control instructions to the laser and the vibrating mirror through the computer, and can mark the designed graphics on the workpiece. So what should be paid attention to when operating the laser marking machine in use?

(2) Key switch, the control panel of the laser is equipped with a key switch, only when the key switch is turned on, the laser can emit light. (3) Laser marking, the technical parameters such as laser output wavelength, power and pulse width are marked on the surface of the laser head, and the danger warning sign is pasted on the front of the laser head. The upper triangular label indicates the direction of laser emission, while the lower strip window shows the laser hazard warning, see Figure 1.

The laser output from the laser of the ultraviolet laser marking machine directly shoots into the human eyes, which will cause serious damage to the eyes and even cause blindness. The most noteworthy thing in the process of using laser is to protect the safety of eyes. In addition to the main beam, there are also small beams at various angles in the vicinity of the laser system.

These beams are formed by the specular reflection of the main beam off various polished surfaces such as lenses, mirrors, and other optical components. Although these beams are very weak compared to the main beam, they can still cause greater damage to the human eye. The laser beam is very strong, it can burn people's skin, burn clothes and paint on the surface, even if it travels a considerable distance, it can still ignite volatile substances, such as organic solvents, etc.

Laser beams can also cause damage to photosensitive elements in optical cameras and LEDs, as well as indirect contact from reflective surfaces. Operators need to keep the following safety precautions in mind during use: 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 lbs Normal01. It is strictly forbidden to open the shell of the laser cavity under any circumstances. 2. For Class 4 laser products, identification plates should be placed near the laser operating area.

3. Reflected light and scattered light are also harmful. Avoid looking directly at the output beam of the laser. 4. Protective goggles must be worn when using the laser (the 355nm band has high reflectivity). 5. The equipment integrator should make the optical path system as closed as possible.

6. One principle must be followed during use: the light path cannot be at the same height as the human eyes. Due to the special nature of the laser beam, compared with the light generated by ordinary light sources, the laser has a certain degree of danger. All laser operators and those working near the laser system must be clearly aware of the dangers of the laser during use.

Only by being familiar with laser equipment and having a full understanding of the coherence and light intensity of laser beams can the safety of laser operators be guaranteed. 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 pt Normal0.
