Description
Technical Field
[0001] This utility model belongs to the field of battery production technology, and in particular relates to a rolling device for flexible graphite monopolar plates used in battery production. Background Technology
[0002] In the battery manufacturing industry, the rolling process of flexible graphite monopolar plates plays a decisive role in battery performance and quality. Traditional flexible graphite monopolar plate rolling equipment used in battery production is widely employed by major battery manufacturers. Its main purpose is to improve the physical properties of flexible graphite monopolar plates through rolling operations, such as increasing plate density and flatness, thereby meeting the basic quality requirements of battery production. These traditional devices typically employ relatively simple structural designs and rolling methods to achieve the rolling process of flexible graphite monopolar plates.
[0003] Traditional rolling devices have relatively fixed roller positions and pressure adjustment methods, and lack a feedback mechanism for pressure adjustment. This makes it difficult to flexibly adjust the pressure based on the characteristics of different parts of the flexible graphite monopolar plate and the differences between batches of plates. For example, because the edges and center of the plate may have slight differences in material properties and thickness, the mechanical properties and feedback during the rolling process differ, resulting in varying rolling pressure requirements. However, traditional devices cannot precisely adjust the pressure to address these differences. This leads to unevenness in density and flatness of the rolled plates, severely affecting the overall performance and quality stability of the battery. This is mainly because traditional designs do not fully consider the differences in characteristics of different parts of the electrode plate and the variations in electrode plates from different batches. They also lack an effective mechanism for flexibly adjusting the rolling pressure. In the actual battery production process, the rolling device often needs to work in conjunction with other processing equipment and needs to flexibly adjust the working angle and position of the rolling device according to different production layouts and process requirements. However, traditional rolling devices are usually fixed in a certain position and lack a convenient rotation docking mechanism. This means that when it is necessary to change the working angle or position, operators have to spend a lot of time and manpower to reinstall and debug, which seriously reduces production efficiency and increases production costs.
[0004] To address these issues, we provide a rolling device for flexible graphite monopolar plates used in battery production. Utility Model Content

[0028] Example 2 Please see Figure 1-6Based on Embodiment 1, an annular plate 21 is fixedly connected to the bottom of the horizontal plate 2. A groove 22 is provided at the bottom of the annular plate 21. A slider 23 is slidably connected to the inner wall of the groove 22. The bottom of the slider 23 is fixedly connected to the top of the box 1. The transverse moving part 46 includes a housing 461, which is fixed to the top of the inner cavity of the connecting frame 43.

[0029] Specifically: The arrangement of the annular plate 21, the slide groove 22, and the slider 23 provides stable support and guidance for the rotation of the horizontal plate 2, ensuring that the horizontal plate 2 rotates smoothly under the drive of the rotating docking mechanism 3. This avoids equipment damage or a decrease in rolling accuracy due to unstable rotation, enhancing the stability and reliability of the rotating docking process. The transverse moving part 46, through the combination design of the lead screw 462, the moving sleeve 464, and the second motor 463, can precisely control the transverse movement of the pressure roller 476, allowing the pressure roller 476 to cover different positions of the flexible graphite monopolar plate, further improving the uniformity and comprehensiveness of rolling, ensuring that all parts of the plate are fully and evenly rolled. The slide rod, guide rail, and guide block provide multiple precise guides for the movement of the moving sleeve 464, ensuring that the moving sleeve 464 moves smoothly and accurately on the lead screw 462, effectively improving the working accuracy of the transverse moving part 46, thereby improving the consistency and stability of the rolling effect and reducing the problem of uneven rolling caused by movement deviation. The adjustable rolling part 47, through the electric telescopic rod 472, pressure sensor 474, and pressure roller 463, can achieve the following: The 76 mechanism allows for real-time and precise adjustment of the rolling pressure according to actual needs, and the pressure data is fed back in real time by the pressure sensor 474, enabling precise control of the rolling process. This design effectively improves the rolling quality of flexible graphite monolayers, ensuring that each plate is rolled under appropriate pressure, meeting the stringent quality requirements of battery production. The setting of the limiting hole and limiting rod effectively restricts the movement direction of the connecting frame 43, ensuring the stability of the connecting frame 43 when the hydraulic telescopic rod 42 drives it up and down, thus ensuring the smooth progress of the entire rolling process and avoiding uneven pressure or equipment failure caused by the unstable movement of the connecting frame 43, thereby improving the reliability of the rolling operation. The configuration of the controller and battery provides intelligent control and independent power supply for the equipment, facilitating precise control and management of the equipment, and is unaffected by unstable external power factors. The base plate ensures the stability of the equipment placement, and the inspection plate facilitates the inspection and maintenance of the internal components of the housing 1, reducing the difficulty and cost of equipment maintenance and improving the maintainability and service life of the equipment.
[0030] The working principle of this utility model is as follows: The first motor 31 in the rotating docking mechanism 3 is activated. The output end of the first motor 31 drives the first gear 32 to rotate. The first gear 32 meshes with the second gear 34 at the bottom of the rotating rod 33, causing the rotating rod 33 to rotate under the support of the bearing at the top of the housing 1. Since the top of the rotating rod 33 is fixedly connected to the bottom of the horizontal plate 2, it drives the horizontal plate 2 to rotate around the axis of the rotating rod 33. This rotation action realizes the angle adjustment between the horizontal plate 2 and the housing 1, which not only facilitates the docking of the rolling device with other processing equipment, improving the applicability of the device, but also allows for adjustment of the feeding and unloading angles according to actual production needs, providing a better fit for the upper and lower parts of the machine. The material handling process is convenient. The uniform rolling mechanism 4 is installed on the top of the horizontal plate 2. When it is necessary to roll the flexible graphite monopolar plate, the hydraulic telescopic rod 42 is activated first. The hydraulic telescopic rod 42 extends, driving the connecting frame 43 and the pre-pressure plate 45 connected to both sides of the bottom of the connecting frame 43 by springs 44 to move downwards until the bottom of the pre-pressure plate 45 is in close contact with the flexible graphite monopolar plate placed on the base plate. At this time, the springs 44 and the pre-pressure plate 45 cooperate with the base plate to pre-press and position the flexible graphite monopolar plate, ensuring that the plate is stable in position during the rolling process. Then, the electric telescopic rod 472 is activated. The electric telescopic rod 472 extends, driving the connecting plate 473 and the pre-pressure plate 45 fixed on the base plate to move downwards. The pressure sensor 474, fixing frame 475, and pressure roller 476 at the bottom of the connecting plate 473 move downwards. The pressure roller 476 is located above the pre-pressing plate 45. As the pressure roller 476 moves downwards, it begins to apply pressure to the pre-pressing plate 45, thereby pressurizing the flexible graphite monopolar plate below. The pressure sensor 474 detects the pressure applied to the plate in real time and feeds the pressure data back to the controller to achieve precise control of the rolling pressure. At the same time, the transverse moving component 46 is activated. The second motor 463 in the transverse moving component 46 drives the lead screw 462 to rotate. The moving sleeve 464, which is slidably connected to the lead screw 462, rotates through multiple sliding rods, guide rails, and guide blocks. Under the guidance of the guide, the roller 476 moves laterally along the direction of the lead screw 462. Since the bottom of the moving sleeve 464 is connected to the adjustable rolling element 47, the pressure roller 476 moves laterally and rolls laterally on the pre-pressing plate 45 to achieve uniform rolling of the flexible graphite monopolar plate. In this process, the pre-pressing plate 45 plays the role of dispersing pressure and ensuring that the pressure is evenly distributed on the flexible graphite monopolar plate, thereby improving the rolling quality. In addition, this solution can also roll the current collector graphite coated metal electrode plate. The current collector graphite coated metal electrode plate requires greater pressure when rolling, which can be increased by controlling the stroke of the hydraulic telescopic rod 42 and the electric telescopic rod 472.
