Description

Technical Field

[0001] The invention relates to the technical field of sodium ion battery production, and in particular to an electrode sheet cutting device for sodium ion battery production. Background Art

[0002] Sodium-ion batteries have the characteristics of high safety, no pollution, low cost and long life, and can meet the requirements of large-scale energy storage systems. As one of the key technologies for the development and utilization of renewable energy (such as solar energy and wind energy) and the construction of smart grids, their research and industrialization have received more and more attention. This paper reviews the development history, principles, material systems and industrialization status of aqueous sodium-ion batteries. It also briefly introduces demonstration and application examples at home and abroad, and points out the direction of future key technologies and industrial development. After rapid development in recent years, sodium-ion batteries have developed a series of positive and negative electrode materials with high specific capacity and high cycle stability.

[0003] In the related technology, the electrode sheet to be cut is placed on a pad, and then the electric push rod is started to retract. The electric push rod drives the bracket and the fixed ring to descend through the guide frame, and the fixed ring drives the pressure ring through the second return spring to initially clamp and fix the electrode sheet to be cut, thereby achieving the effect of initial fixation. At the same time, the guide frame drives the connecting rod and the guide cylinder to descend, and the guide cylinder drives the pressure block through the first return spring to clamp and fix the electrode sheet to be cut, thereby achieving a simple and convenient multiple fixation effect, avoiding the situation where the electrode sheet shakes during the cutting process and affects the cutting quality, thereby improving the cutting accuracy of the electrode sheet cutting device.

[0004] However, during the electrode sheet cutting process, a large amount of debris will be generated during the cutting contact between the cutting drill bit and the electrode sheet. The debris will float and adhere to the electrode sheet, which requires the electrode sheet to be cleaned again, increasing the processing time of the electrode sheet, making it inconvenient to quickly cut the electrode sheet and reducing the cutting efficiency of the electrode sheet.

[0047] In this embodiment, after the cleaning wheel 9 cleans the debris on the electrode sheet, the debris will be cleaned to the debris drop port 11, and then the exhaust fan 143 will supply air to the ventilation pipe 141, and then the debris will be adsorbed and collected by the exhaust head 142, so that the debris is collected in the collection box 12. At the same time, the setting of the filter screen 13 is convenient for shielding the debris, so that the debris stays on the filter screen 13 to avoid the debris blocking the exhaust head 142. When there is a lot of debris on the filter screen 13, the exhaust head 142 is pulled outward. The collecting box 12 is pulled out from the workbench 1. At this time, the movement of the electric telescopic rod 155 drives the movement of the second slider 153, and the second slider 153 drives the movement of the slide plate 151.

[0050] In this embodiment, when cleaning the debris on the surface of the filter screen 13, the collecting box 12 is pulled outward and the collecting box 12 is pulled out of the workbench 1. Then, the slide plate 151 and the cleaning brush 152 are moved from left to right, so that the debris on the surface of the filter screen 13 can be cleaned to the slag outlet 16.

In this way, during the downward movement, the cleaning wheel 9 first contacts with the electrode sheet, and then contacts with the electrode sheet in the subsequent movement. During the continuous downward movement, the deflection plate 8 and the cleaning wheel 9 are driven to deflect to the two sides of the cutter 7 under the push of the cutting frame 6, and then the electrode sheet can be cut while the cutter 7 moves downward. When the electrode sheet is cut, the hydraulic cylinder 5 drives the cutting frame 6 and the cutter 7 to move upward and reset. At this time, under the elastic action of the first spring 105, the first slider 103 is driven to move upward and reset. The first slider 103 drives the reset plate 101 to move upward and reset. The reset plate 101 drives the deflection plate 8 to reset through the connecting rod 102, thereby driving the reset movement of the cleaning wheel 9. Under the movement of the cleaning wheel 9, the debris adhered to the surface of the electrode sheet can be cleaned to reduce The residue of debris on the surface of the electrode sheet reduces the time of cleaning the electrode sheet again, facilitates the rapid cutting of the electrode sheet, and improves the cutting efficiency of the electrode sheet. After the cleaning wheel 9 cleans the debris on the electrode sheet, the debris will be cleaned to the debris drop port 11, and then the exhaust fan 143 supplies air to the ventilation pipe 141, and then the debris is adsorbed and collected by the exhaust head 142, so that the debris is collected in the collection box 12. At the same time, the setting of the filter 13 is convenient for shielding the debris, so that the debris stays on the filter 13 to avoid the debris blocking the exhaust head 142. When there are a lot of debris on the filter 13, the collection box 12 is pulled outward to remove the collection box 12 from the workbench 1 The filter screen 13 is pulled out from the inner part, and the movement of the electric telescopic rod 155 drives the movement of the second slider 153, and the second slider 153 drives the movement of the slide plate 151, and the slide plate 151 drives the movement of the cleaning brush 152, so that the cleaning brush 152 cleans the debris on the surface of the filter screen 13 to reduce the residual debris on the surface of the filter screen 13.
