This allows the hot air to contact the lithium battery cells more evenly and efficiently, accelerating moisture evaporation, improving drying efficiency, shortening drying time, and enhancing overall production efficiency. Furthermore, the nozzle is adjustable, allowing for adjustment of the hot air spray angle and intensity via a second control mechanism. This enables flexible adjustment of the hot air spray pattern based on the different specifications, quantities, and drying requirements of the lithium battery cells, ensuring more precise application of hot air to the cells and further optimizing the drying effect. This meets diverse drying process requirements and effectively solves the problems of poor drying effect and low cleanliness in ordinary lithium battery cell drying devices.

[0020] In this embodiment, the air filter 3 has a multi-stage filtration structure, which can sequentially filter large particulate impurities, fine dust and harmful gases in the air, wherein one end of the connector 301 extends into the interior of the drying box 5.

[0021] Specifically, the air filter 3 adopts a multi-stage filtration structure, which can sequentially filter large particulate impurities, fine dust and harmful gases in the air. This can effectively ensure the cleanliness of the air entering the drying chamber 5, avoid impurities and harmful gases from polluting or corroding the lithium battery cells, improve the quality of the drying environment, and ensure the performance and quality of the battery cells after drying.

[0022] In this embodiment, the first control mechanism 4 and the second control mechanism 10 are integrated with a display screen and operation buttons for setting drying parameters and displaying the operating status of the device.

[0023] Specifically, the first control mechanism 4 and the second control mechanism 10 are integrated with display screens and operation buttons. Operators can easily set parameters such as drying temperature, time, and hot air intensity through these interfaces, and at the same time view the operating status of the device in real time, such as current temperature and humidity, working time, etc., which greatly improves the convenience of operation and the ability to monitor the drying process.

[0024] In this embodiment, the temperature and humidity sensor 7 monitors the temperature and humidity inside the drying chamber 5 in real time and feeds the data back to the first control mechanism 4 and the second control mechanism 10. The surface of the drying tray 11 is provided with ventilation holes to facilitate the circulation of hot air inside the drying chamber 5 and improve drying efficiency. The nozzles provided at the bottom of the nozzle assembly 12 are adjustable nozzles, which can adjust the hot air spray angle and intensity through the second control mechanism 10.

[0025] Specifically, the temperature and humidity sensor 7 monitors the temperature and humidity inside the drying chamber 5 in real time and feeds the data back to the first control mechanism 4 and the second control mechanism 10. The control mechanisms adjust the working state of the hot air box 9 in a timely manner based on the feedback data, such as adjusting the hot air temperature and wind speed, to ensure that the temperature and humidity inside the drying chamber are always maintained within the set range, achieving precise temperature and humidity control. This is beneficial for the uniform drying of lithium battery cells and avoids the impact of temperature and humidity fluctuations on the drying effect and cell quality. The surface of the drying tray 11 is provided with ventilation holes to facilitate the circulation of hot air inside the drying chamber 5. The hot air can contact the lithium battery cells more evenly and efficiently, accelerate the evaporation of moisture, improve drying efficiency, shorten drying time, and improve overall production efficiency.

[0026] In summary, this lithium battery cell drying device allows for the following preparation steps when using the main body 1: Open the door 6, place the lithium battery cells to be dried on the drying tray 11, ensuring proper placement of the cells to guarantee sufficient contact with hot air, close the door 6 to ensure the drying chamber 5 is well-sealed, and set the required drying parameters, such as drying temperature, time, and hot air intensity, through the displays and operation buttons of the first control mechanism 4 and the second control mechanism 10. Air filtration: Upon activation of the device via the first control mechanism 4, air first enters the air filter 3, undergoing multi-stage filtration to remove large particles, fine dust, and harmful gases, resulting in clean air. The clean air enters the drying chamber 5 through the connector 301. Temperature and humidity monitoring and feedback: The temperature and humidity sensor 7 monitors the temperature and humidity inside the drying chamber 5 in real time and continuously feeds the monitoring data back to the first control mechanism 4 and the second control mechanism 10. Hot air supply and drying: The hot air box 9 begins operation, generating hot air. The hot air is delivered to the nozzle 12 through the air supply pipe 901 and then sprayed into the drying chamber 5. The operator can adjust the hot air spray angle and intensity of the nozzle 12 through the second control mechanism 10 according to the actual situation, so that the hot air acts evenly on the lithium battery cells on the drying tray 11, removing the moisture on the surface and inside of the cells for drying. During this process, if the temperature and humidity data fed back by the temperature and humidity sensor 7 deviates from the set value, the first control mechanism 4 and the second control mechanism 10 will automatically adjust the working state of the hot air box 9, such as adjusting the heating power and fan speed, to maintain the temperature and humidity stability inside the drying box. Drying completion prompt: When the drying time reaches the preset value, the device automatically stops the hot air supply. At this time, the buzzer 8 sounds a prompt to remind the operator that the drying operation has been completed. Removing the cells: The operator opens the door 6 and removes the dried lithium battery cells from the drying tray 11, completing the entire drying process. Therefore, this utility model is a very practical product and is worth promoting and applying.
