Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, and in particular to a rapid dehumidification and drying mechanism for square battery electrode strips. Background Technology

[0002] The square battery electrode strip is the core conductive component of a square lithium battery, mainly divided into positive electrode strip and negative electrode strip. The substrate and main material of the positive and negative electrodes directly determine the energy density, charge and discharge efficiency and cycle life of the square battery. Inside the battery, the positive and negative electrodes are separated by a separator, forming the core area of ​​the electrochemical reaction, which is the key carrier for realizing the storage and release of electrical energy.

[0003] In the production process of square batteries, a dehumidification and drying mechanism is required. This mechanism is a key piece of equipment in the production of square lithium batteries, specifically designed to dry and remove moisture from the electrode strips. Freshly made battery electrode strips will have residual moisture on their surface. This moisture can affect the battery's energy storage capacity, consistency, and even safety. The dehumidification and drying mechanism is a device that can quickly remove the moisture from the electrode strips and dry them. However, existing equipment generates a large amount of water vapor when drying the moisture on the electrode strips, which can damage the equipment. If dehydration is performed, the hot air will be drawn away and needs to be reheated, which increases energy consumption, raises production costs, and results in significant losses. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, hot air is injected through a pipe into the ventilation hole and passes through a uniform air distribution plate. The inner wall of the uniform air distribution plate has multiple dispersion holes, which disperse the hot air and evenly reach the outer shell. This dries the surface moisture of the electrode strip, forming water vapor, which is then drawn into the filter box by a centrifugal fan.

At the same time, the guide roller guides it to pass correctly through ventilation duct one, thus achieving the effect of smoothing out the wrinkles on the electrode strip and facilitating subsequent processing.

[0040] Working principle: First, hot air is injected through the duct from the ventilation hole 17, and flows downward along the ventilation duct 3. It passes through the air distribution plate 4. Because the inner wall of the air distribution plate 4 has multiple dispersion holes 11, the hot air is dispersed and flows downward evenly. Then it reaches the outer shell 1, where the heat dissipates and dries the surface moisture of the electrode strip passing through the outer shell 1, causing it to evaporate into water vapor. Then, due to its weight, it continues to flow downward, passing through the exhaust duct 5 and then through the second ventilation duct 12. It is then sucked in by the centrifugal fan 6 and discharged into the filter box 7. Then, the suction fan 10 in the return pipe 9 rotates and draws in the water vapor. The water vapor passes through the drying plate 8 and is filtered to remove the moisture. Then, it flows through the return pipe 9 back to the ventilation duct 3 to re-dry the electrode strip and circulate. The filtered moisture condenses into water droplets and flows out through the drain pipe 21, achieving the effect of hot air recycling and saving production costs.

[0041] First, the electrode strip enters through the feed inlet 201, passes through the outer casing 1, and exits through the discharge outlet 202. The fixed shaft 203, threaded shaft one 204, and threaded shaft two 205 press the electrode strip in place, fixing it in the middle. The electrode strip continues to move backward for subsequent processing, causing the fixed shaft 203 to rotate. At the same time, threaded shaft one 204 and threaded shaft two 205 rotate, and their surfaces are wrapped with threads. The threads on the surfaces of threaded shaft one 204 and threaded shaft two 205 are wrapped in opposite directions. The electrode strip passes through, causing threaded shaft one 204 and threaded shaft two 205 to rotate, making the threads on the surfaces of threaded shaft one 204 and threaded shaft two 205 rotate in opposite directions, providing a force to move to both sides, smoothing out the wrinkles on the surface of the electrode strip. At the same time, it is guided by the guide roller 208 to pass correctly through the ventilation duct one 3, achieving the effect of smoothing out the wrinkles on the electrode strip and facilitating subsequent processing.
