Description

Technical Field

[0001] This utility model relates to the field of sodium-ion battery production technology, and in particular to a pressing device for sodium-ion battery electrodes. Background Technology

[0002] Sodium-ion batteries are rechargeable batteries that primarily rely on the movement of sodium ions between the positive and negative electrodes to function, similar to the working principle of lithium-ion batteries. Sodium-ion batteries have stood out among current new energy storage devices due to their advantages such as high safety, strong thermal stability, and excellent electrochemical performance, and are expected to partially replace or supplement lithium-ion batteries. In the preparation process of sodium-ion battery electrodes, battery electrode coating is required, followed by drying and pressing processes to produce qualified positive / negative electrode sheets.

[0003] As disclosed in patent number CN217641409U, a pressing device for sodium-ion battery electrodes clamps and fixes the battery electrodes by means of a clamping assembly, which prevents the battery electrodes from shifting or deviating, improves the placement stability of the battery electrodes, ensures that the pressure plate has a good pressing effect on the battery electrodes and high pressing efficiency, and greatly reduces the probability of defective sodium-ion batteries.

[0004] The above-mentioned technology has the following drawbacks: when pressing sodium-ion batteries, there are often some particulate impurities left over from the production process on the surface of the sodium-ion batteries. These particulate impurities will have an adverse effect on the sodium-ion batteries during pressing, leaving a significant hidden danger for the future use of the sodium-ion batteries. At the same time, it is impossible to press sodium-ion batteries of different sizes. In order to overcome the shortcomings of the existing technology, we propose a pressing device for sodium-ion battery electrodes. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1-3As shown, a pressing device for sodium-ion battery electrodes includes a main body 1 and a conveying device 2. The conveying device 2 is sleeved inside the main body 1. Two sets of dust collection devices 4 are symmetrically arranged inside the main body 1. A cleaning device 3 is installed above the two sets of dust collection devices 4. A servo motor 8 is installed on the front side of the cleaning device 3. A threaded column 9 is arranged inside the cleaning device 3. A threaded block 10 is arranged on the surface of the threaded column 9. A moving plate 14 is arranged at the lower end of the threaded block 10. A brush strip 15 is attached to the lower surface of the moving plate 14. Two sets of sliding grooves 11 are symmetrically arranged inside the cleaning device 3. A slider 12 is arranged inside the two sets of sliding grooves 11. One end of the two sets of sliders 12 is connected to the threaded block 10 through a connecting long block 13.

[0026] Specifically, the sodium-ion batteries to be pressed are placed on the surface of the conveying device 2. The conveying device 2 conveys multiple sets of sodium-ion batteries at equal distances. When the sodium-ion batteries move to the bottom of the cleaning device 3, the conveying device 2 stops conveying. The servo motor 8 will drive the threaded column 9 to rotate inside the cleaning device 3. When the threaded column 9 rotates, it will drive the moving plate 14 to move inside the cleaning device 3 through the threaded action with the threaded block 10. When the moving plate 14 moves, it will drive the attached brush strip 15 to clean the surface of the sodium-ion batteries, cleaning off the particulate debris on the surface of the sodium-ion batteries to avoid affecting the subsequent pressing.

[0027] Example 2, as Figure 4-5 As shown, a pressing device for sodium-ion battery electrodes is provided. The main body 1 of the device includes a vacuum cleaner 5. The vacuum cleaner 5 is connected to two sets of vacuum devices 4 through vacuum pipes 16. A set of vacuum nets 17 is installed inside each set of vacuum devices 4. A connecting pipe 18 is installed inside the vacuum device 4 and is connected to the vacuum pipes 16. A fixing ring plate 19 is installed on the rear side of the vacuum net 17. The connecting pipe 18 and the fixing ring plate 19 are connected by a connecting plate 20.

[0028] Specifically, the vacuum cleaner 5 absorbs sodium ions and swept-off particulate matter through two sets of suction pipes 16. The swept-off particulate matter enters the space formed by multiple sets of connecting plates 20 through the suction net 17, and then enters the vacuum cleaner 5 through the connecting pipe 18 and the suction pipe 16 for collection, thus facilitating the absorption and collection of particulate matter.

[0029] Example 3, as Figure 6 As shown, a pressing device for sodium-ion battery electrodes is provided. The lower end of the cylinder 6 is fixedly installed with an installation groove 21. The interior of the installation groove 21 is hollow. The upper end of the pressing plate 7 is installed with an installation block 22. The installation block 22 is provided with installation threaded holes 23 around its perimeter. A fixing nut 24 is fitted inside the installation threaded holes 23.

[0030] Specifically, the mounting threaded holes 23 and the mounting groove 21 can be fitted together. At this time, multiple sets of mounting threaded holes 23 will correspond one by one with the mounting holes around the mounting groove 21. Then, multiple sets of fixing nuts 24 are threaded through the mounting holes and connected to the mounting threaded holes 23, thereby fixing the pressing plate 7 at the lower end of the cylinder 6, so that the cylinder 6 can push the pressing plate 7 up and down to press sodium-ion batteries of different sizes.

[0031] Working principle

[0032] It should be noted that this utility model is a pressing device for sodium-ion battery electrodes. In use, multiple groups of sodium-ion batteries are transported via a conveying device 2 housed inside the main body 1. A servo motor 8 drives a threaded column 9 to rotate. When the threaded column 9 rotates, it drives a moving plate 14 to reciprocate within a cleaning device 3 through the threaded action with a threaded block 10. This causes the brush strips 15 attached to the lower surface of the moving plate 14 to clean the surface of the sodium-ion batteries, removing particulate matter. During cleaning, the vacuum cleaner 5 will absorb the cleaned particulate matter through two sets of suction pipes 16. The particulate matter enters the space formed by multiple sets of connecting plates 20 through the suction net 17 and the fixed ring plate 19, and then enters the vacuum cleaner 5 through the suction pipes 16 for easy collection and processing. The cylinder 6 can push the pressing plate 7 up and down to press the sodium-ion battery. The fixing nut 24 can install and remove the pressing plate 7 through the thread action between it and the mounting threaded hole 23, which makes it convenient to install pressing plates 7 of different sizes to press sodium-ion batteries of different sizes.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
