Description

Technical Field

[0001] This utility model relates to the field of battery tab production technology, and in particular to a surface treatment device for battery tab production. Background Technology

[0002] Battery tabs are indispensable current-carrying components in the structure of lithium batteries, connecting the active material of the cell to the external electrodes. Their structure consists of two parts: first, a highly conductive metal base strip (aluminum strip is commonly used for the positive electrode, and copper or nickel-plated copper strip is commonly used for the negative electrode); second, a high-temperature resistant insulating adhesive covering the surface of the metal strip to prevent contact between the metal and the battery encapsulation film, which could cause safety issues. In battery production, the tabs need to be precisely connected to the cell electrodes using processes such as laser welding to ensure stable current transmission. High-quality tabs must possess characteristics such as low resistance, corrosion resistance, and aging resistance. Their quality significantly impacts the energy density, charge / discharge speed, and safety of the lithium battery. During battery tab production, surface treatment is required, such as grinding the edges of the tabs. Currently, the devices used for grinding battery tab surfaces are inconvenient for collecting dust after grinding, so improvements are needed. Utility Model Content

[0056] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a surface treatment device for producing battery tabs.

[0057] A surface treatment device for battery tab production includes a machine body 1 and a recycling tank 2, the recycling tank 2 being disposed within the machine body 1. It also includes an edge grinding assembly 3 disposed on the machine body 1 for surface treatment of the battery tabs; a fixing mechanism disposed on the machine body 1 for fixing the battery tabs; a cleaning mechanism disposed on the machine body 1 for cleaning operations, the cleaning mechanism including two mounting members 4, both mounted on and fixedly connected to the machine body 1; a moving member 5 disposed within and slidably connected to the mounting members 4; two pushing plates 6, both mounted on and rotatably connected to the moving members 5; two connecting columns 7, both mounted on and fixedly connected to the pushing plates 6; a fixing member 8 disposed on and fixedly connected to the moving members 5; a first motor 9 disposed on and fixedly connected to the moving members 5; and a first threaded rod 10 disposed at and fixedly connected to the output end of the first motor 9.

[0058] refer to Figure 3 and Figure 4 In a preferred embodiment, the cleaning mechanism further includes: a mounting housing 11, disposed on the mounting member 4 and fixedly connected to the mounting member 4; a second motor 12, disposed inside the mounting housing 11 and fixedly connected to the mounting housing 11; two lead screws 13, disposed inside the mounting member 4 and rotatably connected to the mounting member 4; and two sprockets 14, disposed on the lead screws 13 and fixedly connected to the lead screws 13.

[0059] When the machine is set up in this way, the edge grinding component 3 starts working to grind the surface of the battery tabs. During the grinding process, the dust generated falls into the recycling tank 2 inside the machine body 1. After the grinding is completed, the third motor 17, the fourth motor 23, and the cylinder 21 start working again, driving the components back to their initial positions. Then, the cleaning mechanism starts operating. First, the position of the push plate 6 is adjusted, which drives the first threaded rod 10 to rotate via the first motor 9, causing the fixing part 8 to move and driving the connecting column 7 inside the fixing part 8 to move. The connecting column 7 slides inside the fixing part 8 and moves with the fixing part 8 towards the side closer to the first motor 9. At the same time, the connecting column 7 drives the push plate 6 to rotate, so that the two push plates 6 form an angle. Then, the second motor 12 drives the sprocket 14 to rotate, which drives the lead screw 13 to rotate. When the lead screw 13 rotates, it drives the moving part 5. The moving part 5 is moved closer to the second motor 12, which in turn moves the push plate 6 on the moving part 5. The push plate 6 cleans the dust on the perforated plate 25 and the placement plate 24, pushing the dust into the recycling tank 2 for collection. Finally, the dust is manually collected and cleaned. The moving part 5 moves in the opposite direction to the adjustment direction of the fixed part 8, so that the angle of the push plate 6's stroke can be such that the dust is directed towards the center during cleaning. A blocking plate is set on the fixed push plate 6. When the moving plate rotates to a certain angle, the blocking plate restricts the rotation of the push plate 6 and prevents the push plates 6 on both sides from having a cleaning dead angle in the center after rotation. The sprockets 14 are connected by a chain, and one of the sprockets 14 is fixedly connected to the output end of the second motor 12. The fixed part 8 is threadedly connected to the first threaded rod 10.

[0060] refer to Figure 2 In a preferred embodiment, the fixing mechanism includes: an installation part disposed in the recycling tank 2 for component installation; two movable parts disposed on the installation part for component movement; two fixing parts disposed on the movable parts for fixing the battery tabs; and a rotating part disposed on the installation part for adjusting the position of the battery tabs.

[0061] refer to Figure 3 and Figure 5 In a preferred embodiment, the installation unit includes: a mounting bracket 15, which is disposed in the recycling tank 2 and fixedly connected to the recycling tank 2; and a fixing plate 16, which is disposed in the recycling tank 2 and fixedly connected to the recycling tank 2.

[0062] refer to Figure 5In a preferred embodiment, the moving part includes: a third motor 17, which is disposed in the recycling tank 2 and fixedly connected to the recycling tank 2; a second threaded rod 18, which is disposed at the output end of the third motor 17 and fixedly connected to the output end of the third motor 17; and a moving block 19, which is disposed on the threaded rod and fixedly connected to the threaded rod.

[0063] When the system is set up in this way, the third motor 17 drives the second threaded rod 18 to rotate, which in turn drives the moving block 19 to move on the second threaded rod 18. The moving block 19 drives the fixed block 20 to move to the appropriate position. At this time, the cylinder 21 works and pushes the stabilizing plate 22 to firmly clamp the battery tab, ensuring that the battery tab will not shift during the grinding of the corners of the battery tab.

[0064] refer to Figure 5 In a preferred embodiment, the fixing part includes: a fixing block 20, which is disposed on and fixedly connected to the moving block 19; a cylinder 21, which is disposed inside the fixing block 20 and fixedly connected to the fixing block 20; a stabilizing plate 22, which is disposed at the output end of the cylinder 21 and fixedly connected to the output end of the cylinder 21; and a stabilizing column 26, which is disposed inside the recycling tank 2 to ensure the stable movement of the fixing block 20 and the moving block 19.

[0065] refer to Figure 5 In a preferred embodiment, the rotating part includes: a fourth motor 23, which is disposed on the fixed plate 16 and fixedly connected to the fixed plate 16; a placement plate 24, which is disposed on the output end of the fourth motor 23 and fixedly connected to the output end of the fourth motor 23; and a perforated plate 25, which is disposed on the machine body 1 and fixedly connected to the machine body 1.

[0066] When the battery is set up to work, the fourth motor 23 drives the placement plate 24 to rotate, thereby adjusting the angle of the battery tabs. When grinding the corners of the battery tabs, after grinding one corner, the battery tab is released, and the fourth motor 23 drives the placement plate 24 to rotate to adjust the battery tabs. Then the battery tabs are fixed and ground again. This process is repeated many times to prevent grinding dead corners.

[0067] This device, through its fixing mechanism, effectively ensures the stability and positional accuracy of the battery tabs during surface treatment. Simultaneously, the angle of the battery tabs can be flexibly adjusted as needed during processing to prevent grinding dead angles. The device also features a cleaning mechanism that automatically and thoroughly cleans the working area after surface grinding, concentrating dust into the recycling tank 2. This avoids the tediousness of manual cleaning and prevents secondary dust contamination. Furthermore, the rotatable design of the push plate 6 prevents dust from leaking out from both sides during dust removal.

[0068] Working Principle: When using this device, the battery tabs are placed on the placement plate 24. Then, the third motor 17 and the fourth motor 23 operate first. The third motor 17 drives the second threaded rod 18 to rotate, which in turn drives the moving block 19 to move along the second threaded rod 18. The moving block 19 moves the fixed block 20 to the appropriate position. At this time, the cylinder 21 operates, pushing the stabilizing plate 22 to firmly clamp the battery tabs, ensuring that the battery tabs do not shift during the grinding process. The fourth motor 23 drives the placement plate 24 to rotate, thereby adjusting the angle of the battery tabs. Combined with the fixing work of the third motor 17 and the cylinder 21, this allows for more comprehensive and precise grinding of the battery tab edges by changing the position of the battery tabs during the grinding process, preventing any grinding dead angles. After the battery tabs are fixed, the edge grinding component 3 begins to work, grinding the exposed edges of the battery tabs. During the grinding process, the dust generated falls into the recycling tank inside the machine body 1. In step 2, after the grinding work is completed, the third motor 17, the fourth motor 23, and the cylinder 21 work again, driving the components back to their initial positions. Then, the cleaning mechanism starts to operate. First, the position of the push plate 6 is adjusted, and the first threaded rod 10 is rotated by the first motor 9, causing the fixing part 8 to move. This moves the connecting column 7 inside the fixing part 8, which slides inside the fixing part 8 and moves closer to the first motor 9. At the same time, the connecting column 7 drives the push plate 6 to rotate, so that the two push plates 6 form an angle. Then, the second motor 12 drives the sprocket 14 to rotate, which drives the lead screw 13 to rotate. When the lead screw 13 rotates, it drives the moving part 5 to move closer to the second motor 12, and drives the push plate 6 on the moving part 5 to move. The push plate 6 cleans the dust on the perforated plate 25 and the placement plate 24, pushing the dust into the recycling tank 2 for collection. Finally, the dust is manually recycled and cleaned.
