Process Flow Diagram   III. Product Overview The high vacuum oven is used for moisture removal baking of lithium battery cells and electrode sheets. Compared with conventional ovens, it has advantages of stable performance, high vacuum level, short baking time, excellent dewatering and drying effect, and good pressure retention. It is combined with a dedicated high vacuum unit and cooling system to form an independent baking system, replacing conventional traditional ovens. IV. Working Principle Each machine is capable of continuous cyclic operation; the basic process is as follows: open the door, place the cells or electrode sheets into the oven, then set the heating time, vacuum time, and nitrogen time. The system will automatically perform heating and timed gas exchange according to the preset time parameters, thus finishing the baking process.   V. Product Features High Vacuum Design The internal chamber is made using pressure vessel standard welding process, with high vacuum retention, long durability, and no deformation. Stable Temperature Uniformity Temperature uniformity reaches ±3℃ under constant temperature. Optimized Space Design The internal chamber size can be customized according to the customer’s battery size, improving space utilization efficiency. Precise Temperature Control Temperature is controlled using silicon-controlled rectifier (SSR) + PID mode, with low thermal inertia and good control effect. Heating Method Hot air circulates both inside and outside the chamber, maintaining consistent internal and external chamber temperatures. Heat radiation and heat conduction ensure chamber temperature uniformity. During cooling, heating tubes are shut off, and internal heat is carried away by air circulation, accelerating cooling speed. Sixfold Safety Protection Ensures operational safety and product reliability. Automated Program Control PLC program controls heating, vacuuming, and nitrogen injection. Manual/automatic operation modes can be switched. Automatic timed heating is completed by simply setting heating time, vacuum time, and nitrogen time. The system will automatically perform baking and gas exchange. Internal Airflow Structure Uses magnetofluid circulation with good sealing and high temperature resistance.   VI.

Oven length: 1 section of oven × 1.0 m/section = 1.0 m 9. Oven material: both inside and outside are made of stainless steel 10. Oven temperature: room temperature--150℃ adjustable, temperature control accuracy <±5℃; Process flow The electrode sheet base material placed on the unwinding device enters the swing arm tension system after automatic deviation correction. After adjusting the unwinding tension, it enters the coating head, and the electrode slurry is coated according to the setting procedure of the coating system. The coated wet electrode sheet enters the oven for drying by hot air. The tension of the dried electrode sheet is adjusted by the tension system, and the winding speed is controlled at the same time, so that it is synchronized with the coating speed. The electrode sheet is automatically corrected by the correction system to keep it in the center position, and is wound by the winding device. Device 1. Unwinding mechanism (with automatic deviation correction device) The device is composed of servo unwinding, unwinding shaft with tension control, automatic deviation correction system, etc. The coil is pulled out and enters the swing arm tension device after automatic deviation correction. The device transmits the tension change during operation to the tension controller through the sensor, so as to achieve constant tension. 2. Swing arm tension mechanism The mechanism consists of rollers, position sensors, etc. The swing arm tension system absorbs the temporary changes in the storage space due to acceleration, deceleration, unwinding and starting the reel, and space fluctuations during the coating interval, so that the impact on the coating is minimized. The tension of the substrate is adjusted by the position of the swing arm, so that the substrate maintains a constant tension during the coating process, and the unwinding speed and the coating speed are controlled to keep synchronization. 3. Coating mechanism This machine is controlled by PLC and is equipped with high-tech automation equipment of precision machinery and opto-mechanical integration.
