Réparation de laser UV industriel à Francfort

Common faults and maintenance methods of Frankfurt Edge UV lasers of Frankfurt Laser Company are as follows:

Défauts courants

Optical path faults:

Déviation du faisceau : en raison d'une installation inexacte des composants optiques, d'une structure mécanique lâche ou d'un impact externe, la direction de transmission du faisceau laser peut être décalée, affectant la précision du traitement.

Degradation of beam quality: Dust, oil, scratches or damage on the surface of optical components will affect the transmission and focusing effect of the laser, such as uneven spot and increased divergence angle.

Power failure:

Unstable power output: Damage to the internal electronic components of the power supply, aging of the filter capacitor or failure of the power control circuit may cause output voltage or current fluctuations, making the laser unstable and the output power fluctuating.

Power failure to start: Damage to the power switch, fuse blown or power module failure will cause the laser to be unable to connect to the power supply and unable to start normally.

Cooling system failure:

Cooling medium leakage: Aging, damage or improper installation of cooling pipes, joints, radiators and other components may cause cooling medium leakage, resulting in reduced cooling effect and increased laser temperature.

Poor cooling effect: Failure of the cooling pump, blockage of the radiator, insufficient cooling medium flow or excessive temperature will cause the laser to be unable to cool effectively, affecting its performance and stability, and even triggering the protection mechanism to stop the laser from working.

Laser medium failure:

Reduced laser output power: After long-term use, the laser medium will age, be damaged, or be affected by factors such as pollution, excessive temperature, and insufficient pump source power, which will cause the output power to decrease and fail to meet the processing requirements.

Control system failure:

Control software failure: The software may freeze, the interface may not respond, and the parameter setting may be wrong, affecting the normal control and operation of the laser.

Hardware control circuit failure: Failure of components such as chips, relays, and sensors in the control circuit will cause the laser to be unable to receive or execute control instructions, resulting in the laser being out of control or working abnormally.

Méthode d'entretien

Contrôle environnemental :

Temperature: Keep the ambient temperature between 20℃-25℃. Too high or too low temperature will affect the performance and stability of the laser.

Humidity: The ambient humidity should be controlled at 40%-60%. Too high humidity can easily cause condensation inside the laser, and too low humidity can easily generate static electricity and damage the laser.

Dust prevention: Keep the working environment clean, reduce dust pollution, and prevent dust from adhering to optical components and affecting laser output.

Optical component cleaning:

Cleaning frequency: Clean the optical components every 1-2 weeks. If there is a lot of dust in the working environment, the cleaning frequency needs to be increased.

Cleaning method: Use a clean non-woven cloth or lens paper, dip in an appropriate amount of anhydrous ethanol or special optical cleaner, and gently wipe from the center to the edge of the optical component to avoid scratches.

Cooling system maintenance:

Water quality management: The cooling system needs to use deionized water or distilled water, and the cooling water should be replaced regularly every 3-6 months to prevent impurities in the water from damaging the cooling system and laser.

Water temperature control: Ensure that the water temperature of the cooling system is between 15℃-25℃. Too high or too low water temperature will affect the heat dissipation effect.

Pipeline inspection: Regularly check whether the cooling system pipeline has water leakage, blockage, etc. If problems are found, they should be repaired or replaced in time.

Power management:

Voltage stability: Use voltage stabilizers and other equipment to ensure stable voltage of laser power supply to avoid excessive voltage fluctuations that may damage the equipment.

Power grounding: Ensure that the laser power supply is well grounded, with a grounding resistance of less than 4 ohms to prevent static electricity and leakage.

Inspection régulière :

Daily inspection: Before starting the machine every day, check whether the appearance of the equipment is damaged, whether the connecting wires are loose, etc.

Regular comprehensive inspection: Check the wear of optical components at regular intervals.
