[0002] An ion battery is a secondary battery, in which sodium ions mainly work by moving between the positive electrode and the negative electrode, similar to the working principle of a lithium-ion battery. The main materials of a sodium-ion battery are a positive electrode sheet and a negative electrode sheet. The positive electrode sheet and the negative electrode sheet are cut by a corresponding cutting device to meet the battery manufacturing requirements. 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 and the construction of smart grids, the research and industrialization of sodium-ion batteries have received increasing attention.

[0003] In the cutting production of the negative electrode sheet of a sodium-ion battery electrode, graphite powder will be generated at the divided part of the negative electrode sheet cut by the tool. The long-term accumulation of graphite powder is likely to cause the machine to be messy and requires frequent manual cleaning. At the same time, the graphite powder floats in the air, causing harm to personnel. In view of the above problems, we have developed an electrode sheet cutting device for ion battery production. Content of the Utility Model

[0007] In a preferred scheme, a feeding reel is installed on the left side of the upper end of the housing, winding wheels are installed at the upper and lower ends on the right side of the housing, limiting rollers are installed at the left and right ends of the upper end of the housing, and a tool is arranged in the middle of the upper end of the housing.

[0008] The negative electrode sheet on the feeding reel is cut by setting the tool, and the finished products are wound up by two groups of winding wheels at the same time.

[0009] In a preferred embodiment, a gear is connected to the front side of the winding wheel, and a motor is installed on the front side of the upper gear, and the two gears mesh with each other.

[0011] In a preferred embodiment, a belt is connected to the front side of the lower gear, the left end of the belt is connected to a rotating rod, a bevel gear set is connected to the rear side of the rotating rod, a reciprocating lead screw is connected to the left side of the bevel gear set, and the reciprocating lead screw is threadedly connected to the slide rod.

[0012] Through the gear driving the belt, the rotating rod is driven to drive the bevel gear set, causing the reciprocating lead screw to rotate by itself, realizing the reciprocating movement of the slide rod in the chute.

[0013] The present utility model provides an electrode sheet cutting device for ion battery production through improvement. Compared with the prior art, it has the following improvements and advantages:

[0014] First: An electrode sheet cutting device for ion battery production sucks the graphite powder generated by cutting into the collection area by pumping air from the outside at the inlet.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0024] An electrode sheet cutting device for ion battery production disclosed by the present utility model is mainly applied to the scenario of cutting electrode sheets of sodium ion batteries.

[0025] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , an electrode sheet cutting device for ion battery production includes an outer shell 1. A collection mechanism 2 is arranged inside the outer shell 1. The collection mechanism 2 is used for collecting graphite powder generated by cutting electrode sheets. The collection mechanism 2 includes an inlet 201 opened in the middle of the upper end of the outer shell 1. A collection area 202 is opened inside the outer shell 1. A dust-proof cloth bag net 203 is installed inside the collection area 202. Slide grooves 204 are opened at the upper and lower ends inside the collection area 202. Slide bars 205 are slidably connected inside the slide grooves 204. A brush 206 is arranged on the rear surface of the slide bar 205. An air pump 207 is installed at the rear of the outer shell 1;

[0026] In this embodiment: During the electrode sheet cutting process, the air pump 207 is started to evacuate the collection area 202. The air pressure inside the collection area 202 decreases. Therefore, to balance the air pressure inside the collection area 202, air is drawn in from the outside through the inlet 201. During the external air intake, the graphite powder generated by cutting is sucked into the interior of the collection area 202. To prevent the graphite powder from being sucked into the air pump 207 and causing damage, a dust-proof cloth bag net 203 is provided to block the graphite powder inside the collection area 202, facilitating subsequent centralized collection, thereby reducing frequent manual cleaning. At the same time, it prevents the graphite powder from floating in the air and causing harm to personnel. During the long-term graphite powder collection process, by setting the sliding rod to repeatedly displace in the sliding groove 204, since the brush 206 scrapes the dust-proof cloth bag net 203, the graphite powder adhered to the surface of the dust-proof cloth bag net 203 is swept off, preventing the dust-proof cloth bag net 203 from being blocked and improving the utilization rate of the dust-proof cloth bag net 203.

[0027] Referring to Figure 1 , Figure 2 and Figure 4 , in a preferred embodiment, a material feeding reel 3 is installed on the left side of the upper end of the outer shell 1, winding wheels 5 are installed at the upper and lower ends on the right side of the outer shell 1, limiting rollers 4 are installed at the left and right ends of the upper end of the outer shell 1, a cutter 6 is arranged in the middle of the upper end of the outer shell 1, a gear 7 is connected to the front side of the winding wheel 5, a motor 8 is installed on the front side of the upper gear 7, and the two groups of gears 7 are meshed with each other;

[0028] In this embodiment: The material feeding reel 3 feeds the electrode sheet, the limiting rollers 4 correct the conveying track of the electrode sheet, and the cutter 6 cuts the electrode sheet to meet the dimensional requirements of the electrode sheet. The motor 8 drives the upper gear 7 to rotate, synchronously driving the lower gear 7 to rotate, causing the two winding wheels 5 to wind the cut electrode sheet in a positive and negative rotation form synchronously.

[0029] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , in a preferred embodiment, a belt 9 is connected to the front side of the lower gear 7, the left end of the belt 9 is connected to a rotating rod 12, a bevel gear set 11 is connected to the rear side of the rotating rod 12, a reciprocating lead screw 10 is connected to the left side of the bevel gear set 11, and the reciprocating lead screw 10 is threadedly connected to the sliding rod 205;

[0030] In this embodiment: In the first implementation, to prevent the dust-proof cloth bag net 203 from being blocked and to prompt the slide rod to repeatedly displace in the chute 204, mainly while the motor 8 drives the electrode sheet to be wound up, the lower gear 7 is synchronously driven to drive the belt 9 to drive the rotating rod 12 to link with the bevel gear set 11, so as to prompt the reciprocating lead screw 10 to rotate on its own. Since the reciprocating lead screw 10 is threadedly connected to the slide rod 205, the slide rod repeatedly displaces in the chute 204. Thus, while the motor 8 drives the take-up wheel 5 to wind up the electrode sheet, the surface of the dust-proof cloth bag net 203 is synchronously scraped.

[0031] Working principle: During use, during the cutting of the electrode sheet, the air pump 207 is started to pump air out of the collection area 202. The air pressure inside the collection area 202 decreases. Therefore, to balance the air pressure inside the collection area 202, air is pumped in from the outside through the inlet 201. During the external air intake, the graphite powder generated by cutting is inhaled into the collection area 202. To prevent the graphite powder from being inhaled into the air pump 207 and causing damage, the dust-proof cloth bag net 203 is provided to block the graphite powder inside the collection area 202, which is convenient for subsequent centralized collection, thereby reducing frequent manual cleaning. At the same time, it prevents the graphite powder from floating in the air and causing harm to personnel. During the long-term collection of graphite powder, by setting the slide rod to repeatedly displace in the chute 204, since the brush 206 scrapes the dust-proof cloth bag net 203, the graphite powder adhered to the surface of the dust-proof cloth bag net 203 is swept off, preventing the dust-proof cloth bag net 203 from being blocked and improving the utilization rate of the dust-proof cloth bag net 203.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
