The reasons and solutions for excessive vibration or noise of laser marking equipment

Reason

1. Fan speed is too high: The fan device is one of the main factors affecting the noise of the laser marking machine. Too high speed will increase the noise.
2. Unstable fuselage structure: Vibration produces noise, and poor maintenance of the fuselage structure will also cause noise problems.
3. Poor quality of parts: Some parts are of poor material or poor quality, and the friction and friction noise are too loud during operation.
4. Change of laser longitudinal mode: The noise of the fiber laser marking machine mainly comes from the mutual coupling of different longitudinal modes, and the change of the longitudinal mode of the laser will cause noise.

Solution

1. Reduce the fan speed: Use a low-noise fan, or reduce the noise by replacing the fan or adjusting the fan speed. Using a speed regulator is also a good choice.
2. Install a noise protection cover: Installing a noise protection cover on the outside of the body can effectively reduce the noise of the laser marking machine. Choose a material with appropriate thickness, such as soundproof cotton, high-density foam plastic, etc., to cover the main noise source and fan.
3. Replace high-quality parts: Replace fans, heat sinks, operating shafts, support feet, etc. with better quality. These high-quality parts run smoothly, have less friction, and have low noise.
4. Maintain the fuselage structure: Maintain the fuselage structure, such as tightening screws, adding support bridges, etc., to ensure the stability of the fuselage.
5. Regular maintenance: Regularly remove dust, lubricate, replace wearing parts, etc. to ensure the normal operation of the equipment and reduce noise.
6. Reduce the number of longitudinal modes: By adjusting the cavity length, controlling the frequency, etc., the number of longitudinal modes of the laser is suppressed, the amplitude and frequency are kept stable, and thus the noise is reduced.

Maintenance and maintenance recommendations

1. Regularly check the fan and parts: Ensure that the fan is running normally and the parts are of reliable quality.
2. Check the fuselage stability: Regularly check the fuselage structure to ensure that the screws are tightened and the support bridge is stable.
3. Regular maintenance: Including dust removal, lubrication, replacement of wearing parts, etc., to ensure long-term stable operation of the equipment.

Through the above methods, the problem of excessive vibration or noise of laser marking machine equipment can be effectively solved to ensure the normal operation and service life of the equipment.
