[0031] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0032] Please see Figures 1-7In this embodiment of the utility model, a battery tab flattening device includes a workbench 1, on which a placement plate 4 is slidably mounted. A groove 13 for placing battery tabs is embedded in the placement plate 4. A driving assembly 9 for driving the placement plate 4 to slide is provided on the workbench 1. A first fixing frame 5 is fixedly mounted on the workbench 1 relative to the placement plate 4. A through-hole 10 is provided on the workbench 1 relative to the placement plate 4. A flattening assembly 7 for flattening the battery tabs on the placement plate 4 is provided on the workbench 1 relative to the through-hole 10. A correction assembly 6 for correcting the deviation of the battery tabs is provided on the first fixing frame 5. The correction assembly 6 includes a support frame 62, which is fixedly mounted on the first fixing frame 5. A first telescopic mechanism 61 is fixedly mounted on the support frame 62. A movable rod 63 is slidably mounted on the first fixing frame 5. The first end of the movable rod 63 is fixedly connected to the telescopic end of the first telescopic mechanism 61. A correction plate 64 is fixedly connected to the first end of the movable rod 63 relative to the groove 13. The correction plate 64 is in contact with the top of the battery in the groove 13.

[0033] Specifically, in this embodiment, the correction component 6 and the flattening component 7 are sequentially arranged on the workbench 1 along the moving direction of the placement plate 4. One end of the placement plate 4 has an opening communicating with the groove 13. The battery tabs are located at the opening end of the placement plate 4. When the placement plate 4 moves, the tail of the battery in the groove 13 first contacts the correction plate 64, and then the front tab of the battery. When flattening the battery tabs, the battery tabs are first placed and fixed in the groove 13 of the placement plate 4. The drive component 9 drives the placement plate 4 to slide on the workbench 1. When the placement plate 4 moves to the first fixing frame 5, the correction plate 64 first contacts the bent tab on the battery (at this time, the tab is bent towards the top of the battery in the groove 13). As the drive component 9 drives the placement plate 4 to move, the correction plate 64 pushes the bent tab to move laterally towards the connection between the tab and the battery. When the correction plate 64 moves to the point where it is connected to the battery, the correction plate 64 moves laterally towards the connection between the tab and the battery. When the ear and battery connection point are aligned, the first telescopic mechanism 61 drives the correction plate 64 to move downward via the movable rod 63, thereby causing the correction plate 64 to move the ear longitudinally, so that the ear and the connection point of the ear and battery are on the same horizontal line. At this time, the correction work of the battery ear is completed. Then, the drive component 9 continues to drive the placement plate 4 to move. When the battery ear on the placement plate 4 moves to the position of the opening 10, the flattening component 7 flattens the battery ear, thereby completing the flattening work of the battery ear. After the flattening work is completed, the battery can be taken out along the groove 13. Then, the drive component 9 drives the placement plate 4 to reset, so as to facilitate the subsequent flattening work of the battery ear. The overall structure is simple to operate and highly automated. The correction component 6 can perform preliminary position correction of the battery ear, ensuring the accuracy of the subsequent flattening operation and improving the quality of the battery ear flattening.

[0034] It should be noted that the driving component 9 is a mechanism that can move the placement plate 4, for example, through the cooperation of the electric slide rail and the slider 91. Meanwhile, the flattening component 7 is a structure that can flatten the battery tabs after correction. For reference, please refer to the publication document with patent announcement number CN215236898U. The specific installation method is the prior art.

[0035] In this embodiment of the utility model, such as Figure 4 and Figure 5 As shown, the correction plate 64 includes an arc-shaped end 641 and a pointed end 642. The pointed end 642 is positioned relative to the sliding direction of the placement plate 4. The pointed end 642 and the arc-shaped end 641 sequentially contact the battery tabs on the placement plate 4. The pointed end 642 is configured to push the battery tabs to move laterally, and the arc-shaped end 641 is configured to push the tabs to move longitudinally. Specifically, when the placement plate 4 slides with the battery tabs, the pointed end 642 first contacts the battery tabs, using its shape to push the battery tabs to move laterally, performing initial correction. As the placement plate 4 continues to slide, the arc-shaped end 641 contacts the battery tab. The first telescopic mechanism 61 moves the correction plate 64 longitudinally, pushing the tab to move in the longitudinal direction, further precisely adjusting the position of the tab. The unique arc-shaped end 641 and pointed end 642 design of the correction plate 64 can adjust the position of the battery tab in stages and in a targeted manner, making the correction effect more accurate and improving the positional accuracy of the battery tab, providing a better foundation for the subsequent flattening operation.

[0036] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the flattening assembly 7 includes a second fixed frame 73, a third fixed frame 72, two sets of third telescopic mechanisms 74, and a pressing plate 71. The second fixed frame 73 and the third fixed frame 72 are fixedly mounted on the workbench 1 along the opening 10. The two sets of third telescopic mechanisms 74 are fixedly mounted on the second fixed frame 73 and the third fixed frame 72, respectively. The two sets of pressing plates 71 are fixedly connected to the drive ends of the two sets of third telescopic mechanisms 74, and the two sets of pressing plates 71 are set opposite to the opening 10. Specifically, when the battery tabs on the placement plate 4 move to the position of the opening 10, the two sets of third telescopic mechanisms 74 on the second fixed frame 73 and the third fixed frame 72 are activated, respectively driving the pressing plates 71 connected to them to move relative to each other, and flattening the battery tabs above the opening 10.

[0037] In this embodiment of the utility model, such as Figure 1 and Figure 3As shown, the drive assembly 9 includes a slider 91, which is fixedly mounted on the placement plate 4. The worktable 1 is provided with a slide groove 94 for the slider 91 to slide in, and a threaded rod 92, which is rotatably mounted on the worktable 1. The threaded rod 92 passes through and is threadedly connected to the slider 91. A motor 93 that drives the threaded rod 92 to rotate is fixedly connected to the worktable 1, as well as a controller 3 that is signal-connected to the motor 93. Specifically, the motor 93 is started under the control of the controller 3, which drives the threaded rod 92 to rotate. Since the threaded rod 92 is threadedly connected to the slider 91, and the slider 91 slides in the slide groove 94 on the worktable 1, the rotation of the threaded rod 92 will cause the slider 91 to move along the slide groove 94, thereby driving the placement plate 4 to slide on the worktable 1.

[0038] In this embodiment of the utility model, such as Figure 4 As shown, a fixing plate 11 is fixedly connected to the first fixing frame 5 relative to the battery tabs on the placement plate 4. A sensor 12 is fixedly connected to the fixing plate 11 facing the battery tabs on the placement plate 4. The sensor 12 is signal-connected to the controller 3. Specifically, the sensor 12 on the fixing plate 11 detects the position information of the battery tabs on the placement plate 4 and transmits this information to the controller 3. The controller 3 controls the operation of the first telescopic mechanism 61 based on the information fed back by the sensor 12, thereby adjusting the position of the correction plate 64 so that the battery tabs accurately reach the designated position. The cooperation between the sensor 12 and the controller 3 realizes real-time monitoring and precise control of the position of the battery tabs, improves the automation level and working accuracy of the device, and ensures the accuracy of the correction and flattening operations. It should be noted that the sensor 12 can be a position sensor or other existing technology.

[0039] In this embodiment of the utility model, such as Figure 1 , Figure 3 and Figure 6As shown, it also includes multiple positioning components 8, which are configured to position the battery tabs within the tank 13. Each positioning component 8 includes a support plate 83 fixedly connected to the placement plate 4, and a connecting plate 82 rotatably mounted on the support plate 83. A pressure plate 84 is integrally formed at the first end of the connecting plate 82, and a second telescopic mechanism 81, with its other end hinged to the second end of the connecting plate 82 and also hinged to the placement plate 4. A rubber pad 14 is fixedly connected to the bottom of the pressure plate 84. Specifically, when fixing the battery within the tank 13, the second telescopic mechanism 81 is activated, causing it to push the connecting plate 82 to rotate around the support plate 83. When the connecting plate 82 rotates, the pressure plate 84 at its first end presses against the battery tabs placed within the tank 13, thus positioning the battery tabs. Located within the groove 13, the rubber pad 14 prevents the battery tabs from moving during the leveling process. When the pressure plate 84 presses against the battery tabs, the rubber pad 14 at the bottom of the pressure plate 84 first contacts the battery tabs. The rubber pad 14 has a certain elasticity, which can provide pressure while avoiding hard damage to the battery tabs. The positioning component 8 can effectively fix the battery tabs within the groove 13, ensuring the stability of the battery tabs during the correction and leveling operations, avoiding poor leveling effect caused by tab movement, and improving product quality. The rubber pad 14 plays a buffering and protective role, preventing the pressure plate 84 from scratching or damaging the surface of the battery tabs during the pressing process, and ensuring the integrity and performance of the battery tabs.

[0040] In this embodiment of the utility model, such as Figure 1 and Figure 2 As shown, the bottom of the workbench 1 is fixedly connected to multiple columns 2.

[0041] Furthermore, in this embodiment, the motor 93, sensor 12, first telescopic mechanism 61, second telescopic mechanism 81 and third telescopic mechanism 74 are all controlled by controller 3. The first telescopic mechanism 61, second telescopic mechanism 81 and third electric telescopic mechanism can be electric telescopic rods, cylinders, etc. in the prior art.

[0042] Working principle: First, the battery is placed in the slot 13 of the placement plate 4 and fixed by the positioning component 8. The drive component 9 drives the placement plate 4 to slide on the worktable 1. When the placement plate 4 moves to the first fixing frame 5, the alignment plate 64 first contacts the bent tab on the battery (at this time, the tab is bent towards the top of the battery in the slot 13). As the drive component 9 drives the placement plate 4 to move, the alignment plate 64 pushes the bent tab to move laterally towards the connection between the tab and the battery. When the alignment plate 64 moves to be level with the connection between the tab and the battery, the first telescopic mechanism 61 drives the alignment plate 64 to move downward through the movable rod 63, thereby causing the alignment plate 64 to move the tab longitudinally, so that the tab and the connection between the tab and the battery are on the same horizontal line. At this point, the correction of the battery tabs is completed. The drive assembly 9 continues to move the placement plate 4. When the battery tabs on the placement plate 4 move to the position of the opening 10, the two sets of third telescopic mechanisms 74 on the second fixing frame 73 and the third fixing frame 72 are activated, respectively driving the pressure plate 71 connected to them to move relative to each other, and flattening the battery tabs above the opening 10. After the flattening is completed, the battery can be taken out along the groove 13. Then, the drive assembly 9 drives the placement plate 4 to reset, so as to facilitate the subsequent flattening operation of the battery tabs. The overall structure is simple to operate and highly automated. The correction assembly 6 can perform preliminary position correction of the battery tabs, ensuring the accuracy of the subsequent flattening operation and improving the quality of the battery tab flattening.
