auto winding machines

When it comes to the production of cylindrical cells, precision is key. Winding machines play a pivotal role in this process, ensuring that each cell is wound to exact specifications. At Yinghe, we understand the importance of these machines in battery manufacturing, so we’ve developed our auto winding machine to deliver efficiency and reliability in every operation. Let’s dive into how you can test these machines for performance and reliability to ensure your production line runs smoothly. 

Performance Testing for Optimal Efficiency

One of the primary factors to test is the performance of the winding machine. The Yinghe auto winding machine boasts an impressive efficiency of 40PPM for 21700 cells. This level of productivity is crucial for manufacturers looking to maximize output. To test its performance, we focus on running the machine continuously for extended periods (24-hour operation) and checking whether it can consistently maintain this rate without issues. We also measure how well it handles variations in material thickness and the quality of the wound cells.

Ensuring High Yield and Minimal Defects

Another critical test for winding machines is the yield rate. A machine like the auto winding machine from Yinghe guarantees a yield rate of ≥99.8%. This translates to fewer defective units and lower waste, which are crucial for maintaining profitability. During testing, we monitor for defects such as uneven winding, poor tab welding, and dimensional inconsistencies. We also use CCD systems to inspect the appearance of each wound cell. These checks help us ensure the machine delivers high-quality output consistently.

Reliability Under Continuous Operation

The reliability of a winding machine is essential for uninterrupted production. The Yinghe auto winding machine is designed for non-stop 24-hour operation. Testing its reliability involves running the machine under full load for long durations to simulate real-world conditions. We assess how well the machine performs after several hours of continuous use, checking for any operational malfunctions or performance dips. Additionally, we check how effectively the system handles minor deviations in material handling and whether the automatic deviation correction functions are responsive and accurate.

Conclusion

In the world of battery manufacturing, the performance and reliability of your winding machine are paramount. At Yinghe, we ensure that our auto winding machines are designed for high efficiency, minimal defects, and optimal long-term performance. Through comprehensive testing, we guarantee that our machines meet the high standards required in the production of 21700 cylindrical cells. With Yinghe, you can trust that your production line will be running at peak efficiency, producing top-quality cells day in and day out.

#34 What are the key steps to integrate winding machines into production lines?

In the ever-evolving world of battery production, the winding machine plays a crucial role in the efficiency and quality of cylindrical cell manufacturing. These machines are responsible for the precise process of winding anode, cathode, and separator materials into a compact structure. The integration of a battery winding machine into the production line involves several strategic steps to ensure that the entire process runs smoothly and meets production goals. Here at Yinghe, we understand how essential it is to incorporate the latest technology for optimizing manufacturing processes. 

Ensuring Equipment Compatibility with Existing Systems

The first and foremost step is to ensure that the winding machine is compatible with the existing systems in the production line. This involves assessing the capacity, speed, and mechanical design of the new machine to make sure it aligns with the rest of the equipment. Yinghe’s battery winding machine models, such as the YHRCW-18/21-3, are designed with flexibility in mind. These machines can handle cylindrical cells with diameters ranging from φ18 to φ21 mm and heights between 40 mm to 70 mm, making them ideal for integration into diverse production environments. The key is to ensure that all equipment communicates seamlessly and the winding machine fits into the workflow without causing any disruption.

Calibration and Adjustment for Maximum Efficiency

After confirming compatibility, the next step is calibration. At Yinghe, we focus on adjusting the settings of the battery winding machine to achieve maximum efficiency. This includes setting the proper tension, speed, and alignment for the winding process. For example, our YHRCW-18/21-3 model operates at an impressive efficiency of 40 PPM, with a qualification rate of ≥99.8%. Calibration ensures that the winding machine produces high-quality cells consistently, reducing the risk of defects and improving the overall yield rate. During this step, precise ultrasonic welding and taping are applied to the cathode and anode tabs, followed by automated defect detection and dimensional measurements.

Streamlining the Workflow and Automation

Once the winding machine is calibrated, integrating it into the automated workflow is the next key step. This is where Yinghe excels in providing cutting-edge solutions. Our machines are equipped with advanced features such as CCD surface defect detection, diameter measurement, and short-circuit testing. These automated processes ensure that each cylindrical cell meets stringent quality standards. After the winding process, cells are automatically transferred to the ATC system for tray loading, significantly reducing manual handling and increasing the overall throughput. This automation streamlines the production process, reduces human error, and increases efficiency.

Conclusion

Incorporating a battery winding machine like the ones we offer at Yinghe is a transformative step for any battery manufacturer looking to optimize their production line. With models like the YHRCW-18/21-3, manufacturers can enjoy high efficiency, minimal defects, and streamlined automation. By ensuring compatibility, calibrating for optimal performance, and integrating automation, the winding machine plays a key role in enhancing production capabilities. At Yinghe, we are dedicated to helping our partners create the best possible battery manufacturing processes, ensuring both high-quality output and operational efficiency.
