Description

Technical Field

[0001] This utility model relates to the field of lithium battery tab processing technology, specifically to a lithium-ion battery tab flattening device. Background Technology

[0002] Lithium-ion polymer battery tabs are an important raw material for lithium-ion polymer battery products. They are metal conductors that lead the positive and negative electrodes out of the battery cell and serve as the contact points for charging and discharging the battery.

[0003] During use, lithium-ion battery tabs can accumulate dust and debris. When flattening the tabs, there is a chance that dust and impurities will stick to the surface of the tabs, causing depressions on the surface and affecting the conductivity of the tabs.

[0004] According to Chinese Patent Publication No. CN218310294U, "A Lithium-ion Battery Tab Flattening Device," the main description involves limiting a sliding block. When the sliding block, slidably connected to the inner wall of a fixed frame, is limited, a rotating block can be rotated. A threaded rod fixedly connected to the rotating block rotates accordingly. The threaded rod rotating on the inner wall of the limiting hole in the sliding block drives the inner clamping plate 1, which is rotatably connected, to move inward. A threaded push rod is rotatably connected to the top of a fixed frame 2, fixedly connected to the top of the device body. Rotating a rotating block fixedly connected to the top of the threaded push rod causes the threaded block threaded to the outer wall of the rotating block to move the inner clamping plate 2 up and down. When the clamping plates 2 and 1 on both sides are symmetrical, pushing the clamping plate 1 inward limits the lithium-ion battery tabs. Pulling the lithium-ion battery tabs flattens them. The overall structure is simple and convenient. However, during the tab flattening process, the tabs are easily dented due to environmental factors and dust, which can damage their conductivity.

[0005] Therefore, a lithium-ion battery tab flattening device is proposed to solve the problem that during the tab flattening process, the tab is easily dented due to the influence of the environment and dust debris, which leads to damage to the conductivity of the tab. Utility Model Content

[0006] The technical problem to be solved by this utility model is that during the flattening process of the electrode tab, it is easy to form a depression due to the influence of the environment and dust debris, which leads to the damage of the conductivity of the electrode tab. Therefore, a lithium-ion battery electrode tab flattening device is proposed.

The third motor drives the two screws to rotate, which can cause the sliders to move. At the same time, the extension of the electric telescopic rod can cause the pressure block to squeeze the tab, thereby cleaning the surface of the tab.

[0009] As a preferred technical solution of this utility model, a fourth motor is fixedly connected to one side of the fixed frame, and a brush roller is fixedly connected to the output end of the fourth motor. The brush roller is driven to rotate by the fourth motor, which can clean the surface of the electrode tab.

[0010] As a preferred technical solution of this utility model, a combing tooth is fixedly connected to the upper side of the fixed frame. The combing tooth contacts the brush roller. By setting the combing tooth, dust and impurities on the brush roller can be removed.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-4 The lithium-ion battery tab flattening device shown includes a fixed frame 1. A first motor is fixedly connected to one side of the fixed frame 1, and a sealing plate 2 is fixedly connected to the output end of the first motor. The first motor drives the sealing plate 2 to rotate, which can keep the fixed frame 1 in a closed state. A limit strip 10 is fixedly connected to the bottom side of the sealing plate 2, and the limit strip 10 contacts the sealing plate 2. A second motor is fixedly connected to one side of the fixed frame 1. The second motor drives a rotating roller 3 and a conveyor belt 4 to rotate, which can move the tabs. A rotating roller 3 is fixedly connected to the output end of the second motor. A conveyor belt 4 is sleeved on the rotating roller 3. A pad 5 is in contact with the inside of the conveyor belt 4. Heat-insulating materials are uniformly fixedly connected to the pad 5. The tube 6 and the fixed frame 1 are rotatably connected to an adjusting rod 7. Rotating the adjusting rod 7 can change the distance between the pressure roller 9 and the conveyor belt 4, thereby adjusting the roller pressure. The adjusting rod 7 is threadedly connected to a movable frame 8. The pressure roller 9 is rotatably connected inside the movable frame 8 and contacts the conveyor belt 4. The fixed frame 1 is fixedly connected to a connecting frame 11. The connecting frame 11 is fixedly connected to both sides of a baffle 12. The baffle 12 is rotatably connected to a guide fan 13. The guide fan 13 can drive the airflow change inside the fixed frame 1, thereby causing the dust on the electrode tab to detach. The bottom side of the fixed frame 1 is provided with a guide groove 14 and a dustproof net 15 is fixedly connected inside the guide groove 14.

[0020] The connecting frame 11 is rotatably connected to a screw 17, and a pressure block 20 is fixedly connected to the bottom end of an electric telescopic rod 19. The electric telescopic rod 19 is fixedly connected to the bottom end of a slider 18. Both sliders 18 are threadedly connected to the screw 17. The screw 17 is fixedly connected to the output end of a third motor. The third motor is fixedly connected to one side of a partition 16. The partition 16 is fixedly connected inside a fixed frame 1. By driving the screw 17 to rotate through the third motor, the two sliders 18 can move. Furthermore, the extension of the electric telescopic rod 19 can cause the pressure block 20 to press down, contact the electrode tab, and squeeze the electrode tab, thereby improving the stability of the electrode tab movement.

[0021] The brush roller 21 is fixedly connected to the output end of the fourth motor, which is fixedly connected to one side of the fixed frame 1. By setting the brush roller 21, the cleaning effect of the electrode ear can be increased.

[0022] The brush roller 21 contacts the combing teeth 22, which are fixedly connected to the upper side of the fixed frame 1. By setting the combing teeth 22, dust and debris on the brush roller 21 are removed.

[0023] Among them, the scraper 23 is fixedly connected to the bottom side of the fixed frame 1. The scraper 23 is in contact with one side of the conveyor belt 4, and the conveyor belt 4 is in contact with the brush roller 21. By setting the scraper 23, the conveyor belt 4 can be cleaned.

[0024] Working principle: Open the sealing plate 2 and put the electrode ear into the fixed frame 1. Then the rotating roller 3 and the conveyor belt 4 rotate, which can drive the electrode ear to move. Then the electric telescopic rod 19 (two electric telescopic rods 19 can contact the electrode ear separately) drives the pressure block 20 to contact one side of the upper end face of the electrode ear. At this time, the guide fan 13 rotates and drives the airflow to contact the surface of the electrode ear. In conjunction with the brush roller 21, it can increase the cleaning effect of the electrode ear. At the same time, the combing teeth 22 can comb the dust on the brush roller 21. After cleaning, the dust approaches and falls on the dustproof net 15 on the left side. Then the electrode ear continues to move, the guide fan 13 is turned off, and after being heated by the heat pipe 6, the electrode ear contacts the pressure roller 9 and is flattened, which improves the flattening effect.
