Introduction：
Battery laser welding machine is a kind of equipment that uses laser technology for welding. It is widely used in the battery manufacturing industry, especially in the production process of lithium batteries. With its high precision, high efficiency and low heat-affected zone, the laser welding machine can meet the high requirements of welding quality, speed and automation in modern battery production. According to different welding needs and process requirements, battery laser welding machines can be classified differently according to laser source, welding method and welding control method.
Laser welder laser source classification
Battery laser welder can be classified according to the laser source used. Common laser source types include solid-state lasers and fiber lasers.
Solid-state laser welder: Solid-state laser welding machines use solid-state lasers as laser sources. Solid-state lasers are usually composed of crystals doped with rare earth elements (such as YAG lasers) or other semiconductor materials. This type of laser welding machine has high energy density, high beam quality and stability, and is suitable for applications with extremely high welding quality requirements. Solid-state laser welding machines can provide a more concentrated laser beam, which can achieve precise and high-quality welding, especially for fine welding of batteries, such as battery internal connecting pieces, lead welding, etc.
Fiber laser welder: Fiber laser welding machines use fiber lasers as laser sources. Fiber lasers use optical fiber to transmit lasers, which can generate high-power and high-efficiency laser beams. They are compact, easy to integrate and highly adaptable. Due to the flexibility and high efficiency of their laser beams, fiber laser welding machines are suitable for battery welding that requires more welding positions, especially battery shell and connecting strip welding in large-scale production.
Laser welder welding method classification
According to different welding methods, battery laser welder can be divided into spot welding machines and wire welding machines.
Spot welding machines: Spot welding machines are mainly used for welding battery connection points. This welding method is usually used to weld the positive and negative plates of the battery or other smaller contact points. Spot welding has a fast speed and low heat input, which can effectively avoid overheating damage to the battery during welding. Spot welding machines are suitable for welding series batteries or parallel batteries. Its advantages are high welding quality, high production efficiency, and accurate welding position.
Wire welding machines: Wire welding machines are mainly used for welding battery connection wires (such as welding battery electrode wires and cable connection wires). Compared with spot welding, wire welding usually requires a slower welding speed, but it can ensure more stable welding quality. It is suitable for long weld connections during battery welding to ensure the strength and durability of the welds. Wire welding machines are often used to connect batteries to external circuits, especially for the production of high-power batteries.
Laser welder welding control classification
According to the different welding control methods, battery laser welder can be divided into manual welding machines and automatic welding machines.
Manual welding machine: Manual welding machines require operators to manually control the welding process, which is suitable for small-batch production, R&D experiments or special occasions with high welding precision requirements. Manual welding machines can be flexibly operated according to the specific requirements of the workpiece, and the operation process is relatively simple, but for large-scale production, the efficiency is low. Manual welding machines are usually equipped with auxiliary equipment such as laser alignment and positioning systems to improve welding quality and operation accuracy.
Automatic welding machine: Automatic welding machines are equipped with automatic control systems, which can realize automatic control of the welding process through preset programs, and are suitable for large-scale industrial production. Automatic welding machines have high welding accuracy and consistency, and can perform continuous welding in a short time to ensure the stability of welding quality. Automatic welding machines realize fully automatic operation through PLC control systems, sensors, visual systems, etc., and can automatically adjust welding parameters, reduce human intervention, and improve production efficiency and quality control
Conclusion
Battery laser welder can be divided into many types according to the laser source, welding method and control mode. Each type of welding machine has its unique advantages and applicable scenarios. Choosing a suitable welding machine not only requires considering the production requirements and welding quality standards of the product, but also comprehensively evaluating production efficiency, automation level and cost factors. Therefore, in the battery production process, the selection of welding equipment plays a vital role in ensuring product quality, improving production efficiency and reducing production costs.
