As a key equipment in modern battery manufacturing, the long-term stable operation of the laser welding machine for supercapacitor is crucial to ensuring battery quality and production efficiency. To ensure that the equipment is always in the best working condition, a comprehensive maintenance and maintenance plan needs to be formulated and implemented.
Daily cleaning of the laser welding machine is a basic and indispensable link. After daily shutdown, the metal debris and oil stains on the surface of the equipment and moving parts such as guide rails and lead screws should be cleaned with a dust-free cloth. These impurities may not only affect the normal operation of the equipment, but also have a negative impact on the welding quality. At the same time, the cleaning of the cooling fan filter should not be ignored. It is recommended to do it once a week to prevent dust accumulation from causing poor heat dissipation, which in turn causes equipment overheating.
Lubrication and tightening are key measures to ensure mechanical accuracy. The lubrication of moving parts such as guide rails and bearings should be checked monthly, and lubricated with special high-temperature grease. In addition, it is necessary to use a torque wrench to check the bolts of key parts, such as the laser head fixing screws, to prevent loosening from causing offset and affecting welding accuracy.
Maintenance of the optical system is the core to ensure the quality of laser welding. As the "eye" of the laser, the cleanliness of the lens is crucial. Use professional lens paper to dip in anhydrous ethanol, and gently wipe the focusing lens and protective lens in a single direction. It is strictly forbidden to use ordinary paper towels or wipe repeatedly to avoid scratching the coating layer. The calibration of the optical path should also not be ignored. The coaxiality of the optical path should be checked with a red light indicator every quarter. When the deviation exceeds the specified value, it needs to be recalibrated to ensure the uniform distribution of laser energy. When the lens is irreversibly contaminated or the coating falls off, it should be replaced immediately, and anti-static gloves should be worn during installation to avoid fingerprint contamination.
Maintenance of the cooling system is equally important. The cooling system can effectively control the operating temperature of the laser and other key components to ensure the normal operation of the equipment. Deionized water or special coolant must be used, and the conductivity must be tested regularly to ensure that the water quality is qualified. The water tank should be thoroughly cleaned every six months to prevent scale from clogging the pipeline. At the same time, it is necessary to regularly check whether the water pump is running smoothly and whether there is any leakage in the pipeline. In winter, attention should also be paid to the ambient temperature to avoid freezing and cracking of the cooling water pipeline.
Preventive maintenance is also an important part that cannot be ignored. A detailed maintenance file should be established to record each maintenance time, replacement parts, abnormal phenomena, etc., to form a "health log" for the equipment. By analyzing the alarm code frequency, the equipment parameters can be optimized in a targeted manner, such as reducing the peak power to extend the life of the laser. In addition, the manufacturer should be contacted every year to conduct airtightness testing on the laser resonator, and replace aging sealing rings, cable connectors and other wearing parts.
The long-term maintenance and maintenance of laser welding machine for supercapacitor is not only a technical work, but also a production attitude. Through meticulous maintenance and scientific and reasonable maintenance plans, it can ensure that the equipment is always in the best working condition, providing a solid guarantee for the company's efficient production and product quality.
