Description

Technical Field

[0001] This utility model relates to the field of electrode processing technology, specifically a battery electrode cutting device. Background Technology

[0002] Battery tabs are key components in lithium-ion batteries. They are metallic conductors used to lead the positive and negative electrodes out of the cell. In layman's terms, they are the contact points between the positive and negative electrodes of the battery during charging and discharging.

[0003] When cutting battery tabs, existing cutting equipment does not fix the top and bottom of the battery tabs. The battery tabs are softer than other metals, and during cutting, the battery tabs are easily bent by the cutting force applied by the blade, which affects product quality and may even damage the tabs, causing the entire battery to be discarded and resulting in losses.

[0004] Different battery products have different size and shape requirements. Cutting tabs can adjust the length of the tabs according to the needs of battery design to ensure that the overall structure and performance of the battery meet the design requirements. However, existing cutting equipment often cannot adjust the cutting distance when cutting tabs of different battery models, which cannot meet the actual needs. Utility Model Content

[0009] The cutting mechanism includes a cutting tool, a lifting assembly, two pressing assemblies, two upper pressure plates, and two lower pressure plates. The lifting assembly is located above the worktable, the cutting tool is located below the lifting assembly, the two pressing assemblies are located on both sides of the cutting tool, and each upper pressure plate is located below one of the pressing assemblies.

[0010] The sliding mechanism includes a baffle and an adjustment assembly.

[0011] As a further embodiment of this utility model, the rotating assembly includes a first motor, a U-shaped frame, a rotating rod, two hinged rods, and two sliding frames. The U-shaped frame is fixedly mounted on the bottom surface of the workbench, the first motor is fixedly mounted on the bottom surface of the U-shaped frame, the rotating rod is rotatably mounted above the U-shaped frame, and the middle part of the rotating rod is fixedly connected to the output end of the first motor. The two sliding frames are slidably mounted on both sides of the workbench. One end of each hinged rod is rotatably connected to one end of the rotating rod, and the other end of each hinged rod is rotatably connected to a sliding frame. Each clamping plate is fixedly mounted above a sliding frame.

[0012] As a further embodiment of this utility model, the lifting assembly includes a vertical plate, a cylinder, a sliding plate, a connecting plate, and a mounting plate. The vertical plate is fixedly mounted on the top of the base plate, the cylinder is fixedly mounted on one side of the vertical plate, the sliding plate is slidably mounted on the vertical plate, and the output end of the cylinder is fixedly connected to the sliding plate. The connecting plate is fixedly mounted on the side of the sliding plate away from the vertical plate, the mounting plate is fixedly connected to the side of the connecting plate away from the sliding plate, and the cutter is fixedly mounted on the bottom surface of the mounting plate.

[0013] As a further embodiment of this utility model, each pressing component includes four sliding rods and four springs. Each sliding rod is slidably mounted on the mounting plate. The bottom ends of the four sliding rods are fixedly connected to an upper pressure plate. Each lower pressure plate is located below an upper pressure plate, and each lower pressure plate is detachably fixedly mounted on the top of the worktable.

[0014] As a further embodiment of this utility model, the adjustment assembly includes a second motor, a lead screw, and a groove. The groove is located on the top of the worktable. The second motor is fixedly mounted on one side of the vertical plate. One end of the lead screw is rotatably connected to the inner wall of the groove, and the other end of the lead screw is fixedly connected to the output end of the second motor.

[0015] As a further embodiment of this utility model, the top of the workbench is provided with four sliding grooves, and every two sliding grooves are slidably connected to a sliding frame.

[0016] As a further embodiment of this utility model, two guide rails are provided on one side of the vertical plate, and the sliding plate is slidably connected to the two guide rails.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model discloses a battery tab cutting device. After the battery is fixed, when the battery needs to be cut, the controller controls the cylinder to work, which drives the sliding plate to slide downward, causing the mounting plate to move downward, thereby driving the cutter to move downward. The cutter cuts the tabs on the battery. When the mounting plate moves downward, it also drives multiple sliding rods to move downward. The multiple sliding rods drive two upper pressure plates to move downward. The two upper pressure plates can work with two lower pressure plates to fix the battery tabs first, preventing the cutter from directly contacting the battery tabs and applying pressure to the tabs, which would cause cutting deformation, i.e., the tabs would bend. While fixing the battery tabs, the cutter can continue to descend to cut the battery tabs.

[0019] 2. The battery tab cutting device of this utility model, when it is necessary to cut tabs of the same length, controls the second motor to rotate through the controller, drives the lead screw to rotate, and makes the baffle slide inside the groove. The position of the baffle is adjusted longitudinally to adjust the insertion depth of the battery tab between the two upper pressure plates and the two lower pressure plates, so that the cutter can cut tabs of different lengths according to actual needs, to ensure the overall structure and performance of the battery, and improve the flexibility and practicality of the device.

[0020] 3. The battery tab cutting device of this utility model, when it is necessary to cut the battery tabs, firstly, the battery is placed on the top of the worktable, and the side of the battery with the tabs is pressed against the baffle. After the battery is placed, the controller controls the first motor to rotate, which drives the rotating rod to rotate. The rotating rod drives the two hinge rods to move, which in turn drives the two sliding frames and two clamping plates to move closer to each other on the top of the worktable. The two clamping plates fit and limit the battery to prevent the battery from shifting, which would affect the cutting effect. This helps to improve the cutting accuracy and also protects the battery. Attached Figure Description

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] like Figures 1-6 As shown, a battery tab cutting device includes a base plate 1 and a worktable 2, and also includes a clamping mechanism, a cutting mechanism and a sliding mechanism. The base plate 1 is fixedly connected to the worktable 2 through multiple support plates.

[0031] The clamping mechanism includes a rotating assembly and two clamping plates 3. The rotating assembly is located below the worktable 2, and the two clamping plates 3 are slidably mounted on the worktable 2.

[0032] The cutting mechanism includes a cutting tool 4, a lifting assembly, two pressing assemblies, two upper pressure plates 5 and two lower pressure plates 6. The lifting assembly is located above the worktable 2, the cutting tool 4 is located below the lifting assembly, the two pressing assemblies are located on both sides of the cutting tool 4, and each upper pressure plate 5 is located below a pressing assembly.

[0033] The sliding mechanism includes baffle 7 and adjustment components.

[0034] like Figures 1-6 As shown, the rotating assembly includes a first motor 8, a U-shaped frame 9, a rotating rod 10, two hinge rods 11, and two sliding frames 12. The U-shaped frame 9 is fixedly installed on the bottom surface of the workbench 2. The first motor 8 is fixedly installed on the bottom surface of the U-shaped frame 9. The rotating rod 10 is rotatably installed above the U-shaped frame 9, and the middle part of the rotating rod 10 is fixedly connected to the output end of the first motor 8. The two sliding frames 12 are slidably installed on both sides of the workbench 2. One end of each hinge rod 11 is rotatably connected to one end of the rotating rod 10, and the other end of each hinge rod 11 is rotatably connected to one sliding frame 12. Each clamping plate 3 is fixedly installed above one sliding frame 12.

[0035] When it is necessary to cut the battery tabs, first place the battery on the top of the workbench 2 and press the side of the battery with the tabs against the baffle 7. After the battery is placed, the controller controls the first motor 8 to rotate, which drives the rotating rod 10 to rotate. The rotating rod 10 drives the two hinge rods 11 to move, which in turn drives the two sliding frames 12 and the two clamping plates 3 to move closer to each other on the top of the workbench 2. The two clamping plates 3 are used to fit and limit the battery to prevent the battery from shifting and affecting the cutting effect.

[0036] like Figures 1-6 As shown, the lifting assembly includes a vertical plate 13, a cylinder 14, a sliding plate 15, a connecting plate 16, and a mounting plate 17. The vertical plate 13 is fixedly mounted on the top of the base plate 1. The cylinder 14 is fixedly mounted on one side of the vertical plate 13. The sliding plate 15 is slidably mounted on the vertical plate 13, and the output end of the cylinder 14 is fixedly connected to the sliding plate 15. The connecting plate 16 is fixedly mounted on the side of the sliding plate 15 away from the vertical plate 13. The mounting plate 17 is fixedly connected to the side of the connecting plate 16 away from the sliding plate 15. The cutter 4 is fixedly mounted on the bottom surface of the mounting plate 17.

[0037] After the battery is fixed, the controller controls the cylinder (14) to work, which drives the sliding plate (15) to slide downward, causing the mounting plate (17) to move downward, thereby driving the cutter (4) to move downward, and the cutter (4) to cut the tabs on the battery.

[0038] like Figures 1-6 As shown, each pressing assembly includes four slide rods 18 and four springs 19. Each slide rod 18 is slidably mounted on the mounting plate 17. The bottom ends of the four slide rods 18 are fixedly connected to an upper pressure plate 5. Each lower pressure plate 6 is located below an upper pressure plate 5, and each lower pressure plate 6 is detachably fixedly mounted on the top of the worktable 2.

[0039] It should be noted that both upper pressure plates 5 are located below the cutter (4). When the mounting plate (17) descends, the two upper pressure plates 5 will contact the battery tabs first, before the cutter (4).

[0040] When the mounting plate (17) moves downward, it will simultaneously drive multiple sliding rods 18 to move downward. Each sliding rod 18 has a limit block fixed at its top to prevent the sliding rod 18 from sliding out of the mounting plate (17). The multiple sliding rods 18 drive the two upper pressure plates 5 to move downward. The two upper pressure plates 5 can work with the two lower pressure plates 6 to fix the battery tabs first, preventing the tool (4) from directly contacting the battery tabs and applying pressure to the tabs to cause cutting deformation, i.e., the tabs bend. After the battery tabs are fixed by the two upper pressure plates 5 and the two lower pressure plates 6, the tool (4) and the sliding rods 18 will continue to descend. At this time, the sliding rods 18 will slide on the mounting plate (17) under pressure. The spring 19 located between the mounting plate (17) and the upper pressure plate 5 will be compressed. While fixing the battery tabs, the tool 4 can continue to descend to cut the battery tabs.

[0041] like Figures 1-6 As shown, the adjustment assembly includes a second motor 20, a lead screw 22, and a groove 23. The groove 23 is located on the top of the worktable 2. The second motor 20 is fixedly mounted on one side of the vertical plate 13. One end of the lead screw 22 is rotatably connected to the inner wall of the groove 23, and the other end of the lead screw 22 is fixedly connected to the output end of the second motor 20. The baffle 7 slides inside the groove 23 and is mounted on the lead screw 22 and threadedly connected to the lead screw 22.

[0042] When cutting battery tabs of different models, the controller controls the second motor 20 to rotate, which drives the lead screw 22 to rotate, causing the baffle 7 to slide inside the groove 23. The position of the baffle 7 is adjusted longitudinally to adjust the insertion depth of the battery tab between the two upper pressure plates and the two lower pressure plates. This allows the cutter to cut tabs of different lengths according to actual needs, ensuring the overall structure and performance of the battery and improving the flexibility and practicality of the equipment.

[0043] like Figures 1-6 As shown, the top of the workbench 2 is provided with four sliding grooves 24, and every two sliding grooves 24 are slidably connected to a sliding frame 12;

[0044] By opening a groove 24 on the top of the workbench 2, the sliding frame 12 is guided to prevent it from shifting and affecting its gripping of the battery.

[0045] like Figures 1-6 As shown, two guide rails 25 are provided on one side of the vertical plate 13, and the sliding plate 15 is slidably connected to the two guide rails 25;

[0046] The two guide rails 25 can guide the sliding plate 15 when it slides, preventing the sliding plate 15 from deviating.
