Description

Technical Field

[0001] This utility model relates to a tab cutting device for lithium battery production, belonging to the field of tab cutting technology. Background Technology

[0002] Tabs are a raw material used in lithium-ion polymer batteries. For example, they are used in everyday items such as mobile phone batteries, Bluetooth batteries, and laptop batteries. Batteries have positive and negative terminals, and tabs are the metal conductors that connect the positive and negative terminals from the battery cell. Simply put, the tabs on the positive and negative terminals are the contact points during charging and discharging. These contact points are not the copper plates on the outside of the battery, but rather an internal connection. Tabs are made of three materials: aluminum for the positive terminal, nickel for the negative terminal, and sometimes copper-plated nickel for the negative terminal. All of these are composed of a composite of a film and a metal strip.

[0003] Existing electrode cutting devices typically use two clamping arms on a clamping device to hold the lithium battery when cutting the electrode tabs. However, after the electrode tabs are cut, the cut battery needs to be manually removed, which is inefficient and time-consuming.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problem of low processing efficiency and time and labor costs associated with manually removing the cut batteries, and to provide a tab cutting device for lithium battery production.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A tab cutting device for lithium battery production includes a processing table and a lifting frame. A hydraulic rod is fixedly connected to the upper surface of the processing table, a tab plate is fixedly connected to the surface of the hydraulic rod, and a mounting plate is fixedly connected to the surface of the tab plate. A transmission roller is rotatably connected to the inner wall of the lifting frame, and a pressure roller is rotatably connected to the inner wall of the lifting frame. A servo motor is fixedly connected to the back of the lifting frame, and the output end of the servo motor passes through the processing table and is connected to the transmission roller for transmission.

[0008] Preferably, the upper surface of the lifting frame is inlaid with connecting rings, which are evenly distributed.

[0009] Preferably, a connecting rod is fixedly connected to the lower surface of the mounting plate, and the inner wall of the connecting ring is slidably connected to the connecting rod.

[0010] Preferably, a connecting seat is fixedly connected to the bottom of the connecting rod, and a cutter is fixedly connected to the lower surface of the connecting seat.

[0011] Preferably, a connecting pipe is fixedly connected to the lower surface of the mounting plate, and the connecting pipe is distributed at the four corners of the lower surface of the mounting plate.

[0012] Preferably, a spring is provided inside the connecting tube, and a fixing rod is provided inside the connecting tube.

[0013] Preferably, a piston is fixedly connected to the top of the fixing rod, and the inner wall of the connecting tube is slidably connected to the piston.

[0014] Preferably, a sealing ring is embedded in the lower surface of the connecting pipe, and the inner wall of the sealing ring is slidably connected to the fixing rod.

[0015] Preferably, the upper surface of the processing table is provided with a cutting groove, and the inner wall of the cutting groove is provided with a wear-resistant layer.

[0016] Preferably, the lower surface of the processing table is fixedly connected with a support leg.

[0017] The beneficial technical effects of this utility model are as follows: The lithium battery tab is placed on the processing table. The hydraulic rod retracts, causing the lifting frame to move downwards. The lifting frame moves downwards, and the lithium battery tab is fixed by the cooperation of the transmission roller and pressure roller. After the lithium battery tab is cut, the servo motor starts, driving the transmission roller to rotate and transfer the lithium battery tab from under the mounting plate, improving work efficiency. The lithium battery tab is placed in the cutting groove, restricting its position. When the mounting plate moves downwards, the lifting frame moves downwards under gravity, causing the transmission roller and pressure roller to contact the lithium battery tab. Then the lifting frame stops moving, and the mounting plate continues to move downwards, causing the connecting pipe to slide against the fixing rod, thereby compressing the spring and generating elastic force, increasing the pressure at the transmission roller and pressure roller. This prevents the lithium battery tab from moving during cutting. Attached Figure Description

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figure 1 - Figure 5 As shown in the figure, this embodiment provides a lithium battery tab cutting device, including a processing table 1 and a lifting frame 5. A hydraulic rod 2 is fixedly connected to the upper surface of the processing table 1, an ear plate 3 is fixedly connected to the surface of the hydraulic rod 2, and a mounting plate 4 is fixedly connected to the surface of the ear plate 3. A transmission roller 6 is rotatably connected to the inner wall of the lifting frame 5, and a pressure roller 12 is rotatably connected to the inner wall of the lifting frame 5. A servo motor 7 is fixedly connected to the back of the lifting frame 5. The output end of the servo motor 7 passes through the processing table 1 and is connected to the transmission roller 6. When the lithium battery tab is placed on the processing table 1, the hydraulic rod 2 retracts, causing the lifting frame 5 to move downward. The lithium battery tab is fixed by the cooperation of the transmission roller 6 and the pressure roller 12. After the lithium battery tab is cut, the servo motor 7 is started, and the servo motor 7 drives the transmission roller 6 to rotate, transferring the lithium battery tab from below the mounting plate 4.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the lifting frame 5 is inlaid with connecting rings 8, which are evenly distributed. The lower surface of the mounting plate 4 is fixedly connected to a connecting rod 9. The inner wall of the connecting ring 8 is slidably connected to the connecting rod 9. The bottom of the connecting rod 9 is fixedly connected to a connecting seat 10. The lower surface of the connecting seat 10 is fixedly connected to a cutter 11. The mounting plate 4 moves down, thereby driving the connecting rod 9 to move down, causing the connecting seat 10 to move downward. The cutter 11 cuts the lithium battery tabs. The connecting ring 8 restricts the direction of movement of the connecting rod 9, making it less likely for the connecting rod 9 to deviate during movement.

[0027] In this embodiment, as Figure 1 - Figure 5 As shown, a connecting pipe 13 is fixedly connected to the lower surface of the mounting plate 4. The connecting pipes 13 are distributed at the four corners of the lower surface of the mounting plate 4. A spring 14 is installed inside the connecting pipe 13, and a fixing rod 15 is installed inside the connecting pipe 13. A piston 16 is fixedly connected to the top of the fixing rod 15. The inner wall of the connecting pipe 13 is slidably connected to the piston 16. The piston 16 restricts the movement direction of the fixing rod 15, making it less likely for the fixing rod 15 to shift. A sealing ring 17 is embedded in the lower surface of the connecting pipe 13. The sealing ring 17 improves the sealing performance of the bottom of the connecting pipe 13. The inner wall of the sealing ring 17 is slidably connected to the fixing rod 15. When the mounting plate 4 moves down... The lifting frame 5 moves downward under the action of gravity, causing the transmission roller 6 and pressure roller 12 to come into contact with the lithium battery tabs. Then the lifting frame 5 stops moving, and the mounting plate 4 continues to move downward, causing the connecting pipe 13 to slide against the fixed rod 15. This compresses the spring 14 and generates elastic force, increasing the pressure at the transmission roller 6 and pressure roller 12, making it difficult for the lithium battery tabs to move during cutting. After the lithium battery tabs are cut, the mounting plate 4 returns to its original position, causing the lifting frame 5 to also return to its original position. Under the elastic force of the spring 14, the relative distance between the mounting plate 4 and the lifting frame 5 is maintained, creating a height difference between the cutter 11 and the transmission roller 6 and pressure roller 12.

[0028] In this embodiment, as Figure 1 As shown, the upper surface of the processing table 1 is provided with a cutting groove 18, and the inner wall of the cutting groove 18 is provided with a wear-resistant layer. The wear-resistant layer improves the wear resistance of the cutting groove 18, which is beneficial to improving the service life of the cutting groove 18. The lower surface of the processing table 1 is fixedly connected with a support leg 19. The lithium battery tab is placed in the cutting groove 18 to restrict the position of the lithium battery tab, so that the lithium battery tab is not easy to move during cutting.

[0029] In this embodiment, as Figure 1 - Figure 5 As shown in this embodiment, the working principle of the electrode cutting device for lithium battery production is as follows:

[0030] Step 1: Place the lithium battery tab in the cutting groove 18, with the lithium battery tab positioned below the cutter 11;

[0031] Step 2: The hydraulic rod 2 retracts, causing the lifting frame 5 to move downwards. This causes the transmission roller 6 and pressure roller 12 to come into contact with the lithium battery tabs. Then, the lifting frame 5 stops moving, and the mounting plate 4 continues to move downwards, causing the connecting pipe 13 to slide against the fixed rod 15. This compresses the spring 14, generating elastic force and increasing the pressure at the transmission roller 6 and pressure roller 12, making it difficult for the lithium battery tabs to move during cutting. The mounting plate 4 moves downwards, causing the connecting rod 9 to move downwards, and the connecting seat 10 moves downwards. The cutting blade 11 cuts the lithium battery tabs. The connecting ring 8 restricts the direction of movement of the connecting rod 9, making it difficult for the connecting rod 9 to deviate during movement.

[0032] Step 3: After the lithium battery tabs are cut, the servo motor 7 is started, and the servo motor 7 drives the transmission roller 6 to rotate, transferring the lithium battery tabs from under the mounting plate 4.

[0033] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
