Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, specifically to a drying device for lithium battery manufacturing. Background Technology

[0002] Drying equipment in lithium battery manufacturing is primarily used to remove moisture from battery materials. This is an essential step in the battery manufacturing process, as moisture has a significant impact on battery performance. Excessive moisture can lead to problems such as electrolyte deterioration, increased internal pressure, high internal resistance, high self-discharge, low capacity, poor cycle life, and even leakage, thus greatly degrading battery performance. Drying equipment provides energy to vaporize and release moisture from wet materials, thereby achieving the purpose of drying. In lithium battery manufacturing, drying equipment typically utilizes technologies such as hot air circulation and vacuum drying to remove moisture. In conclusion, drying equipment plays a crucial role in lithium battery manufacturing. By rationally selecting and optimizing drying equipment and its process parameters, the performance and production efficiency of lithium batteries can be significantly improved, while reducing energy consumption and costs.

[0003] Chinese Patent Publication No. CN221005863U discloses a drying device for lithium battery manufacturing, including a housing. A ventilation opening is provided inside the front side of the housing, and a ventilation hole is provided inside the housing near the ventilation opening. A fan is installed at the bottom of the housing near the ventilation hole, and a discharge hole is provided inside the left side of the housing. This drying device for lithium battery manufacturing, through the arrangement of a feeding pipe, a protruding wheel, a movable rod, a motor body, a movable shaft, an intermittent wheel, a rotating shaft, a connecting column, and a sponge pad, sequentially feeds battery bodies into the feeding pipe. Starting the motor and motor body causes the protruding wheel to rotate, causing one end of the movable rod to disengage from the intermittent wheel. Then, the movable shaft drives the intermittent wheel and the rotating wheel to rotate. Simultaneously, the rotating wheel drives the connecting column to rotate as well. The rotation of the connecting column allows for intermittent separation and feeding of battery bodies, preventing damage or deformation of multiple battery bodies during feeding.

[0004] However, this utility model has the following problems in actual use:

[0005] During use, the lithium battery is placed on the conveyor belt for transmission, making it difficult to air dry the bottom of the lithium battery. This results in incomplete removal of moisture from the bottom of the lithium battery. This uneven drying phenomenon directly affects the overall drying effect of the lithium battery and may even cause subsequent quality problems due to residual moisture at the bottom, reducing the practicality of the device.
