[0002] In the battery manufacturing industry, slurry homogenizers are commonly used in the preparation of battery slurries to facilitate the uniform mixing of electrode materials, conductive agents, binders, and solvents. However, traditional slurry homogenizers have relatively simple stirring structures, which cannot adequately guarantee uniform mixing of the slurry, resulting in poor battery performance consistency. Inability to achieve uniform stirring can easily lead to uneven distribution of components in the slurry, negatively impacting battery production quality, such as unstable battery capacity and significant differences in charge-discharge performance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a battery manufacturing homogenizing device, which solves the technical problem that the stirring structure of traditional homogenizing devices is relatively simple, which cannot fully guarantee the uniform mixing of the slurry, resulting in poor battery performance consistency.

[0004] The purpose and effect of this utility model's battery manufacturing slurry homogenizing device are achieved by the following specific technical means:

[0005] A battery manufacturing homogenizing device includes a base, a stirring assembly and a lifting frame above the base, the stirring assembly being connected to the base via the lifting frame, a stirring tank and a tank cover below the lifting frame, the stirring tank being connected to the tank cover via a magnetic adsorption component, the stirring assembly including a drive motor and a stirring element, the drive motor being installed inside the tank cover, the stirring element being connected to the output shaft of the drive motor, the stirring tank being slidably connected to the base via a sliding component, and a defoaming assembly on one side of the base, the defoaming assembly including a vacuum pump and an ultrasonic transducer, the vacuum pump being connected to a pipe in the tank cover, and the ultrasonic transducer being installed on the stirring element.

[0006] According to a preferred embodiment, the lifting frame comprises two sets of electric push rods and a support plate. The two sets of electric push rods are installed on the top of the base, and the support plate is installed on the movable rods of the two sets of electric push rods.

[0007] According to a preferred embodiment, the defoaming assembly further includes an ultrasonic driver, which is electrically connected to the ultrasonic transducer, and both the ultrasonic driver and the vacuum pump are mounted on the top of the support plate.

[0008] According to a preferred embodiment, the magnetic adsorption component includes an electromagnet and an attraction ring. The electromagnet is disposed on the can lid, and the attraction ring is disposed on the mixing tank. The electromagnet and the attraction ring are magnetically connected. The can lid is mounted on the support plate. The can lid is provided with a positioning post, and the mixing tank is provided with a positioning hole. The positioning post is engaged in the positioning hole.

[0009] According to a preferred embodiment, the stirring component includes a stirring blade and a stirring shaft, the stirring shaft is connected to the output shaft of the drive motor, the stirring blade is installed at the bottom of the stirring shaft, and the ultrasonic transducer is embedded in the stirring shaft.

[0011] According to a preferred embodiment, the sliding member includes a support frame, with casters below the support frame, the mixing tank is mounted on the support frame, and a slide rail is provided on the base, with the support frame slidably connected to the base via the slide rail.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the arrangement of propeller blades, frame blades, and scrapers on the stirring shaft, enables users to achieve uniform mixing of battery slurry. The propeller blades promote the upward and downward circulation of materials, the frame blades expand the mixing range, and the scrapers clean the material from the tank walls, improving the mixing uniformity of the device. During the mixing process, users do not need to worry about material accumulation or insufficient mixing. By observing the mixing status and adjusting parameters such as the mixing speed as needed, the mixing effect can be further optimized, allowing users to obtain a highly uniform battery slurry and improving the device's ability to ensure the quality of the battery slurry.

[0014] 2. When using this device, the user can activate the vacuum pump and ultrasonic driver. The vacuum pump extracts gas from the tank to reduce the pressure, causing air bubbles to escape.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4As shown, this utility model provides a battery manufacturing homogenization device, including a base 11, which provides a stable support foundation for the entire device. A stirring assembly and a lifting frame are located above the base 11. The stirring assembly is connected to the base 11 via the lifting frame, allowing for height adjustment of the stirring assembly to accommodate different stirring needs. Below the lifting frame are a stirring tank 19 and a tank cover 21. The stirring tank 19 is connected to the tank cover 21 via a magnetic adsorption component, ensuring a tight seal during the stirring process and facilitating disassembly. The stirring assembly includes a drive motor 12 and a stirring element. The drive motor 12 is installed inside the tank cover 21, and the stirring element is connected to the output shaft of the drive motor 12. This connection provides power for the stirring process, enabling the stirring element to agitate the materials inside the tank. The mixing tank 19 is slidably connected to the base 11 via a sliding member. This sliding member facilitates the movement of the mixing tank 19, making it convenient for loading, unloading, and individual processing. A defoaming assembly is located on one side of the base 11. This assembly includes a vacuum pump 27 and an ultrasonic transducer 28. The vacuum pump 27 is pipe-connected to the tank cover 21, and the ultrasonic transducer 28 is mounted on the mixing component. The vacuum pump 27 can be an E2M18 model vacuum pump; the ultrasonic transducer 28 can be a KY-100 model ultrasonic transducer. The defoaming assembly eliminates air bubbles generated during mixing, improving the quality of the battery slurry.

[0024] like Figure 2 As shown, the lifting frame consists of two sets of electric push rods 17 and a support plate 18. The two sets of electric push rods 17 are mounted on the top of the base 11, and the support plate 18 is mounted on the movable rods of the two sets of electric push rods 17. By cooperating with the electric push rods 17 and the support plate 18, the lifting height of the support plate 18 can be controlled, thereby adjusting the relative position of the stirring assembly and the stirring tank 19.

[0025] The defoaming assembly also includes an ultrasonic driver 29, which is electrically connected to an ultrasonic transducer 28. This connection allows the ultrasonic transducer 28 to be driven, utilizing the energy of ultrasound to break up bubbles and enhance the defoaming effect. Both the ultrasonic driver 29 and the vacuum pump 27 are mounted on the top of the support plate 18. This mounting arrangement optimizes space utilization and facilitates centralized control and maintenance of the defoaming assembly. The ultrasonic driver 29 can be a US-D10 model.

[0026] The magnetic adsorption component includes an electromagnet 22 and an attraction ring 23. The electromagnet 22 is mounted on the tank cover 21, and the attraction ring 23 is mounted on the mixing tank 19. The electromagnet 22 and the attraction ring 23 are magnetically connected. This magnetic connection allows for connection between the mixing tank 19 and the tank cover 21, while also enabling easy separation when needed. The tank cover 21 is mounted on a support plate 18 and has a positioning post 31. The mixing tank 19 has a positioning hole 32, and the positioning post 31 is engaged within the positioning hole 32. This engagement of the positioning post 31 and the positioning hole 32 ensures proper alignment between the tank cover 21 and the mixing tank 19, guaranteeing the stability of the mixing process and preventing material leakage.

[0027] like Figure 2 , 3 As shown, the mixing component includes a stirring blade 14 and a stirring shaft 13. The stirring shaft 13 is connected to the output shaft of the drive motor 12. The stirring blade 14 is installed at the bottom of the stirring shaft 13. This installation configuration allows the stirring blade 14 to stir the material at the bottom of the tank when the drive motor 12 rotates the stirring shaft 13, promoting mixing. An ultrasonic transducer 28 is embedded within the stirring shaft 13. By embedding the ultrasonic transducer 28 within the stirring shaft 13, ultrasonic waves can be directly applied to the material during mixing, improving defoaming efficiency without occupying additional space.

[0028] The stirring shaft 13 is also equipped with a frame-type paddle 15, on which scrapers 16 are mounted. The combination of the frame-type paddle 15 and scrapers 16 expands the stirring range, while the scrapers 16 scrape off material adhering to the tank wall, resulting in more uniform mixing. The scrapers 16 contact the inner wall of the mixing tank 19, and the frame-type paddle 15 has multiple sets of small holes. The contact between the scrapers 16 and the tank wall, along with the small holes on the frame-type paddle 15, further enhances the cleaning effect on the tank wall and allows the materials to permeate each other during stirring, improving the mixing effect.

[0029] like Figure 2 , 4 As shown, the sliding component includes a support frame 24, with casters 25 positioned below the support frame 24. The support frame 24 and casters 25 provide support for the movement of the mixing tank 19. The mixing tank 19 is mounted on the support frame 24, and a slide rail 26 is provided on the base 11. The support frame 24 is slidably connected to the base 11 via the slide rail 26. The coordinated arrangement of the support frame 24 and the slide rail 26 allows the mixing tank 19 to slide smoothly along the fixed track, facilitating positioning and operation.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In use, place the mixing tank 19 on the support frame 24, aligning the support frame 24 with the slide rail 26 on the base 11. Push the mixing tank 19 to slide it along the slide rail 26 to the desired position. The initial position of the mixing tank 19 on the support frame 24 can be adjusted using the casters 25, facilitating installation and positioning. Simultaneously, check the magnetic adsorption components to ensure that the electromagnet 22 on the tank cover 21 and the attraction ring 23 on the mixing tank 19 are functioning correctly, and that the positioning post 31 on the tank cover 21 engages with the positioning hole 32 on the mixing tank 19, thus connecting the tank cover 21 to the mixing tank 19. The sliding components facilitate the installation, movement, and positioning of the mixing tank 19, ensuring its stable placement within the device. The magnetic adsorption components and positioning structure guarantee the sealing and accuracy of the connection between the mixing tank 19 and the tank cover 21, preventing material leakage during mixing and providing a good foundation for subsequent mixing operations. Then, the drive motor 12 is started, which drives the stirring shaft 13 to rotate. The stirring blades 14 at the bottom of the stirring shaft 13 begin to stir the material at the bottom of the mixing tank 19, promoting initial mixing. Simultaneously, the frame-type blades 15 on the stirring shaft 13 rotate, and the scraper strips 16 on the frame-type blades 15 contact the inner wall of the mixing tank 19, scraping off the material adhering to the tank wall, allowing the material to participate in the stirring more evenly. The small holes on the frame-type blades 15 promote interpenetration between materials, enhancing the mixing effect. The synergistic work of different types of blades improves the uniformity of stirring, ensuring that the components in the battery slurry are fully mixed, which helps to improve the consistency of battery performance.

[0032] According to the stirring requirements, operate the control button to start the two sets of electric push rods 17. The movable rod of the electric push rod 17 rises or falls, driving the support plate 18 and the tank cover 21, drive motor 12 and other components mounted on it to rise and fall together, thereby adjusting the relative position of the stirring assembly and the material in the stirring tank 19. The lifting frame can adjust the height of the stirring assembly to meet the stirring requirements of different amounts of material, and also facilitates the observation, feeding, and unloading of the stirring tank 19 before and after stirring. When bubbles are generated during stirring, the vacuum pump 27 is started. The vacuum pump 27 extracts the gas in the tank through the pipe connected to the tank cover 21, reducing the gas pressure in the tank and making it easier for the bubbles to escape. At the same time, the ultrasonic driver 29 is turned on, driving the ultrasonic transducer 28 embedded in the stirring shaft 13 to work. The ultrasonic transducer 28 emits ultrasonic waves, using the energy of the ultrasonic waves to break the bubbles. The defoaming component uses a physical method to eliminate the bubbles generated during stirring, avoiding the bubbles remaining in the battery slurry and affecting the battery performance, thus improving the quality and stability of the battery slurry. After stirring is completed, first turn off the drive motor 12, vacuum pump 27 and ultrasonic driver 29. Disconnect the power supply to the electromagnet 22 to separate the tank cover 21 from the mixing tank 19, and then raise the tank cover 21 along with the support plate 18. Utilizing the sliding structure of the mixing tank 19, move it to a position easy to clean via the casters 25 and slide rails 26, and clean the interior of the mixing tank 19 and its various components. The arrangement of the components facilitates disassembly and relocation, making cleaning and maintenance easier, helping to keep the device clean, preventing residual materials from affecting the next mixing operation, and extending the device's service life.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
