This method helps to improve the energy density and volume utilization rate of the battery, while ensuring a more uniform electrochemical reaction inside the battery.

[0003] The patent with the application number 201721758551.X relates to a lithium-ion battery winding and injection device, especially including a winding machine. In front of the winding machine, there is an injection component for infiltrating the electrolyte into the winding tape of the lithium battery cell. Its winding and injection structure and process are integrated, significantly shortening the technological process of the lithium battery, simplifying the assembly route, and remarkably reducing the production and processing cost of the lithium-ion battery.

However, this device directly winds the positive electrode, negative electrode, and separator, and it is easy to cause the positive electrode, negative electrode, and separator to be not closely attached during winding, affecting its production quality. Therefore, a lithium-ion battery winding and injection device is proposed to solve the above-mentioned problems. Summary of the Invention

A feeding device is fixedly installed on the front side of the main machine table. A guide rod is fixedly connected to the front side of the main machine table. A rolling component is fixedly installed on the front side of the main machine table. A motor is installed on the inner wall of the rolling component. A slicing table is fixedly connected to the front side of the main machine table. A fixing plate is fixedly connected to the front side of the main machine table. A cylinder is fixedly installed on the inner wall of the fixing plate. A cutting component is fixedly installed at the output end of the cylinder. An electric turntable is rotatably installed on the inner wall of the front side of the main machine table. A winding device is rotatably installed on the inner wall of the electric turntable. A voltage stabilizing component is fixedly connected to the front side of the electric turntable. An injection device is fixedly installed on the front side of the main machine table; a flattening mechanism is arranged on the inner wall of the bottom of the cutting component. A guiding mechanism is arranged on the top of the slicing table. A temperature control mechanism is arranged on the front side of the main machine table; the flattening mechanism includes an elastic plunger rod, a pressing plate, a first fixing block, a first connecting rod, a second connecting rod, a second fixing block and a push rod. The elastic plunger rod is fixedly connected to the side of the cutting component away from the fixing plate. The pressing plate is fixedly connected to the bottom end of the elastic plunger rod. The first fixing block is fixedly connected to both sides of the pressing plate. The first connecting rod is rotatably connected to the circumferential surface of the first fixing block. The second connecting rod is rotatably connected to the inner wall of the first connecting rod. The circumferential surface of the second fixing block is in contact with the inner wall of the second connecting rod. The push rod is fixedly connected to the end of the first connecting rod away from the cutting component; after the electrode material is processed, the electrode material passes through the slicing table and then the winding device winds the electrode material. After winding, the cylinder starts to drive the pressing plate to move to press the electrode material on the slicing table, so that the positive and negative electrodes fit better with the separator, thereby improving the overall performance and charge and discharge efficiency of the battery. At the same time, when cutting after pressing down, the movement of the pressing plate drives the push rod to stretch and flatten the electrode material on the slicing table, having better shape and thickness consistency, and can be more easily wound, ensuring the uniformity and consistency of the battery assembly, making the winding better and faster. The end of the second fixing block close to the elastic plunger rod is fixedly connected to both sides of the pressing plate. The side of the first connecting rod close to the pressing plate is in contact with both sides of the cutting component; the side of the second connecting rod close to the cutting component is in contact with the front and back sides of the pressing plate.

[0006] Preferably, the guiding mechanism includes the third fixed block, the L-shaped connecting rod, the slider, the third connecting rod, the guiding plate, the fourth fixed block, the rotating plate, the fifth fixed block, the fourth connecting rod and the rotating cylinder. The third fixed block is fixedly connected to the front and rear sides of the pressing plate. The L-shaped connecting rod is fixedly connected to the bottom of the third fixed block. One end of the L-shaped connecting rod away from the cutting assembly is fixedly connected with an extension block. The slider is slidably connected to the circumferential surface of the extension block of the L-shaped connecting rod. The third connecting rod is fixedly connected to the top of the slider. The guiding plate is fixedly connected to the top end of the third connecting rod. The fourth fixed block is fixedly connected to the inner wall of the guiding plate. The rotating plate is rotatably connected to the circumferential surface of the fourth fixed block. The fifth fixed block is fixedly connected to the inner wall of the rotating plate. The fourth connecting rod is rotatably connected to the circumferential surface of the fifth fixed block. After the electrode material is cut, the air cylinder drives the guiding plate to move to guide the cut electrode material, ensuring that the electrode material maintains a consistent position and alignment during the winding process, thereby reducing non-uniformity in the manufacturing process and improving the overall quality and performance of the battery. After guiding, the guiding plate moves inward and the rotating cylinder moves to squeeze the electrode material on the slicing table, preventing the electrode sheet from bouncing off due to excessive tension after cutting, allowing the electrode material to pass through slowly, making it not easy for the electrode material to fall off or deform during the winding process, enhancing the service life and safety of the battery.

The rotating shaft is fixedly connected to the inner wall of the pulley. The flapping plate is fixedly connected to the circumferential surface of the rotating shaft. The inner wall of the limiting block is in contact with the circumferential surface of the rotating shaft; when the winding device winds the electrode material, the main machine table will start the heater to control the temperature of the wound electrode material, keeping the electrode material winding at a suitable temperature, preventing the electrode material from expanding or contracting due to temperature changes. Temperature control helps to maintain the dimensional stability of the material, thereby ensuring that the electrode material can be evenly adhered during winding, avoiding the generation of bubbles during winding. At the same time, after the temperature is controlled, the air cylinder drives the flapping plate to rotate to reflux the heated hot air, making the temperature control better, reducing production adjustments caused by temperature fluctuations, and improving production efficiency. The circumferential surface of the rotating shaft is rotatably connected to the inner wall of the main machine table, and the top of the limiting block is fixedly connected to the bottom of the slicing table.

After guiding, the guiding plate moves inward and the rotating cylinder moves to squeeze the electrode material on the slicing table, preventing the electrode sheet from bouncing off due to excessive tension after cutting, allowing the electrode material to pass through slowly, making the electrode material not easily fall off or deform during the winding process, and enhancing the service life and safety of the battery.

[0011] 3. The lithium-ion battery winding and liquid injection device, through the coordinated operation among the heater, L-shaped guiding rod, convex block, pulley, rotating shaft, flapping plate and limiting block.

The materials in the feeding device 2 reach the rolling assembly 4 through the guide rod 3. The rolling assembly 4 rotates to drive the pressed electrode material through the slicing table 5. After the electrode material passes through the slicing table 5, the winding device 11 winds the electrode material.
