Description

Technical Field

[0001] This utility model relates to the field of aluminum-nickel electrode tabs, and in particular to a rapid drying device for aluminum-nickel electrode tabs. Background Technology

[0002] The aluminum-nickel tabs are the core components connecting the lithium battery cell to the external circuit. They are made of aluminum strips and nickel strips through welding (such as ultrasonic welding). The cleanliness and dryness of their surfaces directly affect the safety and cycle performance of the battery. During the production process, the tabs need to be dried quickly after cleaning (removing oil and impurities) to avoid moisture residue leading to poor subsequent welding or gas evolution inside the cell. When drying aluminum-nickel tabs, hot air is used to blow them and remove the surface moisture, which is time-consuming and makes it difficult to know whether the drying is complete in time. If the temperature used for drying aluminum-nickel tabs is too high, it can easily damage the aluminum-nickel tabs, resulting in poor drying efficiency. The hot air used for drying is directly discharged, which can easily lead to waste of resources. Therefore, we propose a rapid drying device for aluminum-nickel tabs. Utility Model Content

The second conveying pipe 204 inputs into the interior of the chamber 202 to preheat it. The temperature and humidity sensor 6 monitors the temperature and humidity inside the chamber 202. If the temperature inside the chamber 202 is too high, the first air inlet 101 and the heating plate 102 are closed and the second air inlet 104 is opened. Outside air enters the interior of the chamber 202 through the second air inlet 104, which cools the interior of the chamber 202. The temperature and humidity sensor 6 monitors the humidity of the discharged air. When the humidity in the air decreases, it means that the drying is complete. The cover plate 501 is positioned on top. After the relevant equipment is turned off, the discharge port 203 and the discharge pipe 505 are opened to discharge the aluminum-nickel tabs.
