Description

Technical Field

[0001] This utility model relates to the field of lithium battery cutting and pretreatment technology, and more specifically, to a lithium battery cutting and pretreatment device. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, use, and environmental requirements for lithium metal are very high. After a long period of use, lithium-ion batteries will be depleted of their energy and must be scrapped. The positive and negative electrode plates of lithium-ion batteries are important components of lithium-ion batteries and have recycling value. Therefore, cutting devices are needed to cut off the positive and negative electrode plates of lithium-ion batteries for recycling.

[0003] A search revealed that utility model patent CN212329893U discloses a lithium battery cutting pretreatment device, including a cutting box. The bottom of the cutting box is fixedly connected to a support foot, and the top left side of the cutting box is fixedly connected to a support frame. This lithium battery cutting pretreatment device uses a servo motor to drive a drive rod to rotate. During the rotation of the drive rod, a gear rotates. Because the gear meshes with a rack, the rotation of the gear sequentially drives the rack, movable rod, push plate, blade plate, and cutting blade to move up and down. During the up-and-down movement of the cutting blade, the positive electrode cutting blade cuts off the positive electrode sheet of the lithium battery, and the negative electrode cutting blade cuts off the negative electrode sheet, achieving the purpose of cutting the positive and negative electrode sheets of the lithium battery. This results in a good cutting effect, effectively cutting the positive and negative electrode sheets from the lithium battery, improving the recovery rate of the positive and negative electrode sheets, and increasing the efficiency of the cutting device.

[0004] However, the above patents still have the following shortcomings: they are not convenient for continuous cutting. When the cutting blade moves up and down, the lithium battery needs to be placed in a fixed position, which affects the cutting efficiency. In addition, manual loading and unloading of the lithium battery to be cut is required, which is not convenient. Therefore, we propose a lithium battery cutting pretreatment device.

[0034] In this embodiment, the spring force of the spring 23 drives the extrusion plate 24 to extrude and fix the lithium battery conveyed on the conveyor belt 4.

[0035] For details, please refer to Figures 2 to 4The bottom surface of the workbench 1 is fixedly connected to multiple support columns 13, and the bottom ends of the multiple support columns 13 are fixedly connected to a base plate 14. The top surface of the workbench 1 and the inner side of the conveyor frame 2 are provided with two first material dropping grooves 11, and the end of the workbench 1 is provided with a second material dropping groove 12. The top surface of the base plate 14 and the bottom of the two first material dropping grooves 11 are respectively placed with electrode collection boxes 15, and the top surface of the base plate 14 and the bottom of the second material dropping grooves 12 are respectively placed with battery collection boxes 16.

[0036] In this embodiment, two electrode collection boxes 15 are used to collect the cut positive and negative electrode sheets, and a battery collection box 16 is used to collect the cut lithium battery cylinders.

[0037] For details, please refer to Figure 2 Multiple support rollers 26 are rotatably connected between the two conveyor frames 2.

[0038] In this embodiment, the support roller 26 is used to support the conveyor belt 4 to ensure the strength of the conveyor belt 4 in supporting and transmitting the lithium battery.

[0039] For details, please refer to Figure 3 , Figure 4 and Figure 6 There is a gap between the side of the conveyor belt 4 and the inner side of the conveyor frame 2. The cutting disc 10 is located between the conveyor belt 4 and the conveyor frame 2, and the cutting disc 10 is located above the first discharge chute 11.

[0040] In this embodiment, the cutting disc 10 is designed to cut the positive and negative electrode sheets at both ends of the lithium battery smoothly, and the cut positive and negative electrode sheets fall from the first discharge trough 11 into the electrode collection box 15.

[0041] For details, please refer to Figure 1 and Figure 5 The distance between the two conveyor frames 2 is equal to the length of the inner cavity of the feeding square tube 17 and the storage tank 21, respectively.

[0042] In this embodiment, the lithium battery is placed in the storage tank 21, and the lithium battery in the storage tank 21 can fall smoothly from the discharge square tube 17 between the two conveyor frames 2. The distance between the two conveyor frames 2 is equal to the length of the lithium battery, and the inner side of the conveyor frame 2 is used to limit the lithium battery.

[0043] Working principle: In operation, the first motor 5 is started to drive a drive roller 3 to rotate, which in turn drives the conveyor belt 4 to rotate. Simultaneously, two second motors 9 are started to drive two cutting discs 10 to rotate. At the same time, lithium batteries to be cut are placed into multiple storage slots 21 on the temporary storage box 20. Then, the electric push rod 19 is started to move the temporary storage box 20, aligning one of the storage slots 21 with the inner cavity of the discharge square tube 17. This causes the lithium batteries in the storage slot 21 to fall through the discharge square tube 17. When the arc-shaped groove 6 on the conveyor belt 4 is just below the discharge square tube 17, the lithium batteries in the discharge square tube 17 fall into the first motor 5. Then, the conveyor belt 4 moves the lithium batteries in the arc-shaped groove 6. When the lithium battery in the arc-shaped groove 6 moves to the bottom of the extrusion plate 24, the spring force of the spring 23 causes the extrusion plate 24 to press and fix the lithium battery. In addition, during the movement of the lithium battery, the rotating cutting disc 10 cuts the positive and negative electrode sheets at both ends of the lithium battery. Finally, the cut positive and negative electrode sheets fall into the electrode sheet collection box 15 through the first dropping groove 11. The cut lithium battery body falls into the battery collection box 16 through the second dropping groove 12. After the lithium battery in one storage groove 21 falls, the electric push rod 19 is activated to drive the temporary storage box 20 to move, so that the other storage groove 21 and the discharge square tube 17 are aligned, so that the lithium battery in the other storage groove 21 falls, so that the lithium battery can be cut continuously.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
