How to improve the production efficiency of lithium battery copper foil?

Advanced technology of electro-deposited copper foil machine:

The electro-deposited copper foil machine adopts a number of innovative technologies to comprehensively improve production efficiency, product quality and operational stability. First of all, the components of the machine equipment include online polishing part, cathode roller drive part, anti-oxidation equipment part, winding part, pickling and washing part, etc., to build a complete and efficient production line. The core control system of the equipment adopts the Japanese Mitsubishi or German Lenz system, which ensures the stability and efficiency of the entire production process with its high precision and fast response speed.
The equipment adopts a servo drive system, whose high control accuracy and good feedback performance enable each link of copper foil production to be completed accurately and accurately. The lithium battery copper foil produced by this equipment has a specification range of 3.5~105μm, which is suitable for various standard and customized requirements, providing a wider production choice for major lithium battery manufacturers.

Tension and temperature control optimization technology of electro-deposited copper foil machine

In order to further improve production efficiency and product quality, the electro-deposited copper foil machine has made a lot of optimizations in control. The equipment uses Mitsubishi or Lenz tension control system with an accuracy of up to ±0.3kg, ensuring the tension stability throughout the production process, thereby avoiding possible quality fluctuations in the copper foil production process. At the same time, the temperature control system used can achieve a temperature control accuracy of ±2℃ during the drying and cooling process, and uses OMRON brand fans to achieve stepless adjustment of air volume.
Accurate tension control system: ensuring the consistency of copper foil
Tension control is a crucial link in the production process of copper foil. Too much or too little tension will lead to uneven thickness of copper foil, which in turn affects its performance and quality. The electro-deposited copper foil machine uses Mitsubishi or Lenz tension control system with a tension control accuracy of up to **±0.3kg**. This control accuracy ensures that throughout the production process, whether it is stretching, copper plating or winding of copper foil, the tension can be maintained within a very stable range.
Avoid tension fluctuations: Tension fluctuations are one of the main factors affecting the quality of copper foil. By accurately controlling the tension, the equipment can effectively avoid problems such as uneven stretching, breakage or surface defects of copper foil, thereby improving the overall quality and production efficiency of copper foil.
Improve production stability: During the production process, copper foil needs to go through multiple processes, and the tension requirements of each process may be different. Mitsubishi or Lenz's tension control system automatically adjusts the tension to ensure that the tension in each process is always in an ideal state, reducing the error of manual adjustment and improving the stability of production.
High-precision temperature control system: ensure the stability of the drying and cooling process
The production of copper foil requires not only precise tension control, but also strict temperature control, especially during the drying and cooling process, temperature fluctuations may affect the thickness uniformity and surface smoothness of the copper foil. Therefore, the electro-deposited copper foil machine adopts a precise temperature control system in these two links to ensure that the copper foil can meet the best process requirements at every step in the production process.
Temperature control accuracy: The temperature control system used in the equipment has an accuracy of up to ±2℃, ensuring that the temperature is always maintained within the specified range during the drying and cooling process. Precise temperature control can effectively avoid surface defects of copper foil caused by excessive temperature difference and ensure the uniformity of copper foil.
Air volume adjustment: In addition to temperature control, the equipment also uses OMRON brand fans, providing stepless air volume control. By adjusting the air volume, the drying and cooling speed of the copper foil can be finely adjusted according to different production needs. This flexible air volume adjustment can increase the production speed and further improve production efficiency without affecting the quality of the copper foil.
Comprehensive optimization: improve production efficiency and product quality
Reduce human intervention: Through the high-precision tension and temperature control system, the equipment can automatically adjust the production parameters, reducing the need for human intervention. This not only improves production efficiency, but also reduces the workload of operators and reduces the impact of human operating errors on product quality.
Improve the automation and stability of the production line: These optimizations enable the production line of the electro-deposited copper foil machine to operate in an efficient and stable state, and maintain high product consistency even in large-scale production. The high-precision control system ensures the stable quality of each batch of copper foil products, thereby improving the efficiency of the entire production process.
Improve the surface quality of the copper foil: During the drying and cooling process, the precise temperature control system ensures the flatness and smoothness of the copper foil surface, while the tension control system maintains the thickness consistency of the copper foil. The combination of the two effectively avoids surface defects and improves the overall quality of the copper foil, especially in lithium battery applications.

3M non-woven polishing wheel and intelligent pressure control technology

In the polishing process, the electro-deposited copper foil machine uses a 3M non-woven polishing wheel, which can provide a fine surface polishing effect. The speed of the polishing wheel can reach 0-600 rpm, and supports stepless adjustment, which can flexibly adapt to different production needs. Moreover, through current detection, the equipment can intelligently distinguish the polishing pressure of the polishing wheel, thereby ensuring uniform polishing and improving the surface quality of the copper foil.
Advantages of 3M non-woven polishing wheel
Fine polishing effect: The 3M non-woven polishing wheel is composed of multiple layers of fibers and particles, which can be evenly distributed on the surface of the copper foil, removing tiny surface defects and irregular textures, and ensuring the smoothness and surface quality of the copper foil. Its soft and flexible structure makes the polishing process more delicate, helping to avoid scratches or other surface defects.
Adjustable speed to adapt to different production needs: The speed of the polishing wheel can be adjusted from 0 to 600 rpm, and supports stepless adjustment. This means that the operator can flexibly adjust the speed of the polishing wheel according to the production needs of different batches. Different speeds can adapt to the processing needs of copper foils of different thicknesses or materials, thereby improving production flexibility and efficiency.
Accurate polishing pressure control: Through the current detection system, the electro-deposited copper foil machine can monitor the pressure changes of the polishing wheel in real time. The change in the current signal can reflect the contact pressure between the polishing wheel and the copper foil surface. The equipment uses this data for intelligent control to ensure that the pressure during the polishing process remains stable, thereby avoiding uneven surface or excessive wear caused by too high or too low pressure. Intelligent detection can also ensure that the polishing pressure is evenly distributed and optimize the overall quality of the copper foil surface.
Improve the surface quality of copper foil: Since the speed and pressure of the polishing wheel can be precisely controlled, the surface of the copper foil has very high uniformity and smoothness after polishing. This not only improves the appearance quality of the copper foil, but also reduces the generation of fine defects on the surface of the copper foil, thereby improving its conductivity and reliability in lithium batteries.
Technical details and operability
Current detection and intelligent regulation: Current monitoring is achieved through real-time analysis of the motor load. According to the changes in polishing pressure, the system automatically adjusts the working parameters to ensure that the equipment is always in the best working condition during the polishing process. This not only improves the accuracy of production, but also avoids errors caused by human operation, making the production process more stable and controllable.
Adjustable swing frequency: In addition to speed control, the equipment also provides 0-300 times/minute swing frequency adjustment. Through the swing function, the polishing wheel can make more extensive contact on the copper foil surface, avoiding local excessive wear and further improving the surface uniformity. The stepless swing frequency also provides more flexibility for production.
