[0002] In the production process of sodium-ion batteries, the processing of pole pieces is one of the important links in the entire production process.

[0003] The prior art generally uses a cutting device for pole pieces to cut the pole pieces. The pole piece cutting device includes a workbench, a feeding push rod, a cutting circular saw and a collecting device for collecting the cut pole pieces. The feeding push rod and the collecting device are relatively arranged on the workbench, and the cutting circular saw is arranged between the two and can cut the material passing through it, and the cutting direction of the cutting circular saw is perpendicular to the feeding direction of the feeding push rod; when in use, the worker will first place the pole piece material plate to be cut between the feeding push rod and the cutting circular saw, and the feeding push rod will slowly push the material plate toward the cutting circular saw along the feeding direction, and the cutting circular saw will cut the part of the pole piece material plate that passes through it from the total material plate after the size of the part of the pole piece material plate reaches a predetermined distance, and finally collect the cut pole piece through the collecting device.

[0004] However, since the circular saw can easily deviate the material plate when cutting the material plate, the cutting accuracy of the electrode cutting device is not high and the yield rate is low.

[0005] In view of this, it is necessary to provide a cutting device and a cutting process for sodium ion battery pole pieces. Summary of the invention

[0006] In order to solve the problem that the existing electrode cutting device is prone to deviate the material plate when cutting the material plate, thereby resulting in low cutting accuracy and low yield rate of the electrode cutting device, the present application provides a sodium ion battery electrode cutting device and a cutting process.

[0007] In a first aspect, the present application provides a cutting device for a sodium ion battery pole piece, which adopts the following technical solution: comprising a workbench, a material moving assembly, a material loading assembly, a cutting assembly and a material collecting assembly, wherein the material loading assembly, the material moving assembly and the cutting assembly are arranged on the workbench along the processing sequence of the pole piece, the material moving assembly comprises a conveyor belt, a mounting frame is arranged on the workbench, the conveyor belt is arranged on the mounting frame and a material moving channel is formed between a belt body at the bottom of the conveyor belt and the workbench;

[0008] The loading assembly can store a plurality of material sheets and convey the material sheets one by one to the inlet of the material transfer channel, so that the conveyor belt can abut against the top of the material sheet and drive the material sheet to pass through the material transfer channel;

[0009] The cutting assembly is arranged at the outlet of the material transfer channel and is capable of cutting off the portion of the material plate extending out of the material transfer channel from the material plate;

[0010] The material collecting assembly is arranged at a side of the cutting assembly away from the material moving channel and can collect the cut pole pieces.

[0011] By adopting the above technical solution, after the material sheet enters the material transfer channel, it will be abutted between the conveyor belt and the table surface of the workbench, and the cutting component will cut the part of the material sheet extending out of the material transfer channel, so that the cutting component is not likely to deviate the material sheet in the material transfer channel when cutting the material sheet, thereby ensuring that the cutting device for sodium ion battery pole pieces has good cutting accuracy for the pole pieces.

[0012] Specifically, the material moving assembly also includes a regularizing block and a driving device. A slide groove is provided on the table top of the workbench along the width direction of the material moving channel. A slider is provided at the bottom of the regularizing block.

The driving device is transmission connected to the regularizing block and can drive the regularizing block to move back and forth along the slide groove.

[0013] By adopting the above technical solution, the driving device can drive the regular block to move back and forth along the slide groove, so that the material plate can fall back into the receiving groove after being deviated by the cutting device, thereby ensuring that the material plate will not be in a skewed state when being cut, thereby ensuring that the cutting device for sodium ion battery pole pieces has better cutting accuracy.

[0014] Specifically, the material moving assembly further comprises a telescopic cylinder, a cylinder body of the telescopic cylinder is arranged on the mounting frame, a piston rod of the telescopic cylinder is connected to the conveyor belt and can drive the conveyor belt to approach or move away from the workbench.

[0018] By adopting the above technical solution, when the piston rod of the pushing cylinder extends from the cylinder body, it can drive the material resisting part to pass through the material resisting port and extend into the accommodating chamber. When the material resisting part extends into the accommodating chamber, it will push the bottom material plate in a stack of material plates in the accommodating chamber from the discharge port into the material transfer channel; and when the piston rod of the pushing cylinder retracts into the cylinder body, the piston rod will drive the material resisting part to leave the accommodating chamber, so that the stack of material plates falls down to the height of one layer of material plates, which is convenient for the next pushing of the material resisting part.

[0019] Specifically, the cutting assembly includes a rotating device, a saw blade and a lifting cylinder. The rotating device is transmission-connected to the saw blade and can drive the saw blade to rotate. The cylinder body of the lifting cylinder is disposed on the mounting frame.

[0020] By adopting the above technical solution, the lifting cylinder can drive the rotating device and the saw blade to approach or move away from the workbench, so that the saw blade cuts the material plate directly below it when it approaches the workbench.

[0021] Furthermore, the cutting assembly also includes a liquid storage tank and a nozzle. The liquid storage tank is arranged on the mounting frame and can store coolant. The nozzle is connected to the liquid outlet of the liquid storage tank through a pipeline and can spray coolant to the saw blade.

[0027] Specifically, the material collection assembly includes a material guide plate, a material collection box and a vibration motor. The material guide plate is arranged between the material collection box and the cutting assembly, and the plate surface of the material guide plate is inclined downward in the direction from approaching to away from the cutting assembly.

[0033] S4, repeat S2 and S3 until all the material plates in the loading assembly are processed.

[0034] By adopting the above technical solution, when the size of the part of the material sheet in the material transfer channel extending out of the material transfer channel reaches the cutting requirement, the user can close the conveyor belt and open the cutting component to ensure that the material sheet will not move when being cut by the cutting component, thereby avoiding the phenomenon of over-cutting due to the movement of the material sheet; when the cutting component cuts off the part of the material sheet extending out of the material transfer channel, the user can close the cutting component and open the conveyor belt to avoid the phenomenon of under-cutting due to the premature opening of the cutting component.
