AI Technical Summary
When the coating machine breaks during lithium battery production, the traditional method requires shutting down the oven temperature and air frequency system to wait for it to cool down, resulting in low production efficiency and oven temperature fluctuations, which affect battery performance.
The system employs a tape-receiving mechanism, including a tape-receiving clamp, a conveyor chain, a servo motor, and a conveyor sprocket. By quickly removing and securing the broken tape inside the oven, the oven temperature system is not shut down. The broken tape is then passed through the oven by the servo motor-driven chain.
It shortens the tape breakage processing time, avoids temperature fluctuations, improves production efficiency, ensures a stable environment inside the oven, and reduces the possibility of safety accidents.

[0002] In the production process of lithium batteries, the coating process is a very critical link. It involves uniformly coating active materials, conductive agents and the like on a substrate to form an electrode sheet, which is an important guarantee for the performance of lithium batteries. The oven is a necessary process after coating, which is responsible for drying and curing the coated electrode sheet to ensure the stable performance of the electrode sheet and meet the requirements of subsequent processing.
[0003] However, the coating machine in the production process of lithium batteries often encounters the problem of belt breakage. Once the belt breaks, not only will it cause the sudden interruption of the production line, seriously affecting the production efficiency, but also it may cause great disturbance to the temperature and air frequency control in the oven. Traditionally, the way to handle such a broken belt is to immediately shut down the temperature and air frequency system of the oven, wait for the oven temperature to completely cool down to a safe range, and then enter the oven for threading operation to pass the foil through the oven again.
