Description

Technical Field

[0001] The utility model relates to the field of feeding, in particular to the field of tab feeding, and specifically to a tab feeding mechanism. Background Art

[0002] Battery tabs are a crucial component within the battery, used to connect the positive and negative electrodes within the cell and serve as contact points during charging and discharging. Tabs are categorized by application into digital tabs and power tabs. The former primarily encompasses, but is not limited to, consumer electronics, while the latter serves, but is not limited to, high-energy-demand sectors such as electric vehicles and energy storage devices. Tabs are typically composed of metal strips and films. Specially processed, they possess excellent electrolyte resistance, corrosion resistance, and stable conductivity, making them crucial to the overall performance of the battery. Tabs come in a variety of specifications, including width, thickness, and material grade, and are customized to meet specific product requirements.

[0003] During battery production, the tab feeding mechanism is a key piece of equipment for automated tab production. Existing tab feeding mechanisms primarily consist of a baffle assembly, a flap assembly, and a feeding device. The baffle blocks and positions the tab, while the flap assembly flaps and conveys the tab. The feeding device transports the tab strip to the next process, meeting the positioning requirements of different tab types.

[0004] However, existing tab feeding mechanisms have several drawbacks during use. First, due to the diverse shapes and sizes of tabs, existing feeding mechanisms lack positioning accuracy and adaptability, making it difficult to meet the demands of high-precision and high-efficiency production. Second, deviations are prone to occur during the tab clamping and feeding process, resulting in poor conveying and positioning of the tab strip, affecting the subsequent production quality and performance of the tab. Furthermore, existing tab feeding mechanisms typically clamp and position the tab strip's film, which inherently has a certain degree of flexibility, making it prone to poor clamping and positioning of the tab, thus hindering the stable conveying and positioning of the tab strip, affecting conveying efficiency and production quality.

[0045] Optionally, the machine adjustment jig 18 is provided with a plurality of tab strips for pairing with tab strips of different shapes and sizes, so that an appropriate machine adjustment jig 18 is selected according to the width of the tab strip.

[0046] In this embodiment, the tab strip is in a "T" shape, that is, the adjustment jig 18 is matched with the shape and size of the tab strip, and the positioning block 10 clamps the protruding ends of the tab extending to both sides, that is, the metal part of the tab strip.

[0052] The specific working process in this embodiment is:

[0053] The reel-type tab material strip is installed on the material tray 3. Two limit rings are provided on the material tray 3 for clamping the tab material strip.

The end of the positioning plate 20 near the guide roller 7 is provided with a guide groove for matching the tab material strip. A transparent pressing plate is installed on the guide groove. After the tab material strip passes through the guide groove, the driving motor 87 drives the clamping claw 9 to move to the end of the mobile module 8 near the guide groove through the movable plate 6. The telescopic end of the clamping cylinder 94 drives the feeding lower clamp 93 to rise and clamp the tab material strip with the feeding upper clamp 92;

[0054] At the same time, the two positioning blocks 10 on the feeding lower clamp 93 are pre-adjusted to a spacing matching the width of the tab material strip according to the machine adjustment fixture 18. Specifically, in this embodiment, raised metal parts are formed on both sides of the width direction of the tab material strip. Under the clamping of the clamping jaws 9, the two positioning blocks 10 can clamp and limit the metal part of the tab material strip, further improving the effect of clamping and positioning the tab material strip. The rotation of the drive motor 87 drives the clamping jaws 9 to move and transport to the cutter 14 through the movable plate 6 to avoid slipping or offsetting during the transportation process. , further ensure the stability and adaptability of clamping, improve the accuracy of clamping and feeding the tab material strip, so that the open end of the tab material strip passes through the through hole and the cutting groove 16 and is exposed to the outside of the cutter 14. At this time, two clamping cylinders 19 are provided on the positioning plate 20, and the two clamping cylinders 19 are distributed at both ends of the positioning plate 20, so that the clamping claw 9 is located between the two clamping cylinders 19. By driving the telescopic end of the clamping cylinder 19 downward, the tab material strip and the upper surface of the positioning plate 20 can be clamped and pressed, so that the tab material strip can be stably cut;

[0055] After cutting, the clamping jaws 9 release the tab strip and move along the movable module 8 to the end close to the material guide trough to clamp the next tab strip. At this time, the clamping limits of the two clamping cylinders 19 are released, and the open end of the tab strip is exposed to the outside of the cutter 14 again. This action is repeated in sequence to complete the stable conveying and positioning of the tab strip, thereby improving the efficiency and accuracy of conveying.

[0056] In summary, by clamping and positioning the tab strip above and below with the clamping claws and clamping and limiting the metal part of the tab strip with the two positioning blocks, the clamped tab strip can be accurately conveyed to the cutting position, thereby enhancing the stability of conveying and positioning. By the relative closeness or distance of the positioning blocks, it can adapt to tab strips of different widths, thereby improving the versatility and flexibility of the feeding mechanism. The clamping claws can press and position the strip, further enhancing the stability of the strip during conveying and avoiding problems such as inaccurate cutting due to shaking or offset.
