The main solutions are to mechanically push the short side directly to position it against the side or to push the short side directly to center it. However, the above two methods of direct pushing and tightening for positioning have a problem: they can cause the tabs to fold or bulge and wrinkle. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.
[0027] See Figure 1 This embodiment discloses a full-pole ear assembly positioning device, including a support beam 1, a first transplanting gripping mechanism 2, a second transplanting gripping mechanism 3, a positioning and correction mechanism 4, and a circulating fixture 5.
[0028] The support beam 1 consists of two sets of U-shaped brackets and a set of long horizontal beams. Specifically, the horizontal beams are fixed on the two sets of U-shaped brackets, and the horizontal beams are set above the material receiving route of the full-tab electrode assembly and the transportation route of the full-tab electrode assembly.
[0029] A first transplanting gripping mechanism 2 and a second transplanting gripping mechanism 3, capable of sliding along the length of the horizontal beam of the supporting beam 1, are provided. In this embodiment, two sets of first transplanting gripping mechanisms 2 and second transplanting gripping mechanisms 3 are respectively provided on both sides of the horizontal beam along its length. Specifically, an electric drive assembly is provided on the horizontal beam, which drives the first transplanting gripping mechanism 2 and the second transplanting gripping mechanism 3 to slide along the length of the horizontal beam. It should be noted that in this embodiment, the first transplanting gripping mechanism 2 and the second transplanting gripping mechanism 3 are commercially available transplanting robots used to grip and transport the full-tab electrode assembly 6, and each set of transplanting gripping mechanisms is equipped with two sets of robots.
[0030] In this embodiment, two sets of positioning and correction mechanisms 4 are provided on both sides below the horizontal beam, so that each set of first transplanting and gripping mechanism 2 can deliver the full-pole tab group 6 to the corresponding positioning and correction mechanism 4 and the second transplanting and gripping mechanism can grip the full-pole tab group 6 on the positioning and correction mechanism 4.
[0031] See Figure 2 and Figure 3 The positioning and correction mechanism 4 includes two sets of positioning and correction components 41 arranged side by side and a set of transplant detection components 42. The positioning and correction components 41 include a positioning sliding module 411 and a clamping module 412. The positioning sliding module 411 is equipped with a clamping module 412 that can move along the long side of the full-tab pole group 6. The clamping module 412 is used to clamp the long side of the full-tab pole group 6. In this embodiment, the clamping module 412 is a centering clamp that can be directly purchased from the market. The transplant detection component 4... 2 includes a detection sliding module 421, a support rod 422, and a shooting module 423. The detection sliding module 421 is provided with a support rod 422 that can move along the direction perpendicular to the long side of the omnipolar electrode group 6. The support rod 422 is provided with two sets of shooting modules 423 from bottom to top. The shooting end of one set of shooting modules 423 is positioned above the omnipolar electrode group 6, and the shooting end of the other set of shooting modules 423 is positioned below the omnipolar electrode group 6. In this embodiment, the shooting modules 423 are all CCD components.
[0032] Specifically, the first transplanting and gripping mechanism 2 grips and places the full-tab electrode assembly 6 onto the clamping module 412, and the clamping module 412 centers and clamps the full-tab electrode assembly 6 along its long side. Then, the detection sliding module 421 is driven to move the support rod 422 along the direction perpendicular to the long side of the full-tab electrode assembly 6. The imaging module 423 takes pictures of the edge position of the negative electrode sheet on each full-tab electrode assembly 6 on the clamping module 412, i.e., along the short side, and compares them with the edge position of the negative electrode sheet initially calibrated by the imaging module 423. If there is a positional deviation, the positioning sliding module 411 is driven to guide and compensate for the displacement in the short side direction. After the displacement compensation is completed, the full-tab electrode assembly 6 is positioned and corrected.
[0033] By using the image capture and positioning of the camera module 423, non-contact guidance and correction of the all-electrode electrode group 5 is achieved, fundamentally eliminating the problem of electrode flipping or bulging and wrinkling caused by secondary positioning of the all-electrode electrode group 5, thus greatly improving the product yield.
[0034] See Figure 4 The circulating fixture 5 is positioned below the moving path of the second transplanting gripping mechanism 3. The circulating fixture 5 includes a circulating moving assembly 51, a tray 52, a spinning spring cylinder 53, and a pressing block 54. The circulating moving assembly 51 is positioned on the transport path of the full-tab electrode assembly 6 and can move to below the moving path of the second transplanting gripping mechanism 3. The circulating moving assembly 51 is provided with a tray 52 for placing the full-tab electrode assembly 6. The tray 52 is provided with two sets of spinning spring cylinders 53. The output end of each spinning spring cylinder 53 is connected to a pressing block 54 for pressing the full-tab electrode assembly 5. The pressing block 54 is also provided with a gasket (not shown in the figure) to prevent damage to the full-tab electrode assembly 5.
[0035] In this embodiment, the circulating moving component 51 is a magnetic levitation moving component, which is used to connect with the magnetic levitation stator on the transport line of the all-tab pole group 6 so that the circulating moving component 51 can drive the pallet 52 to move along the transport direction of the all-tab pole group 6 transport line.
[0036] The working principle of this utility model is as follows: The first transplanting gripping mechanism 2 grips the full-tab electrode assembly 6 on the incoming material route. Then, the electric drive assembly on the horizontal beam drives the first transplanting gripping mechanism 2 to move horizontally above the positioning and correction assembly 41 and place the gripped full-tab electrode assembly 6 on the clamping module 412. The clamping module 412 then centers and clamps the full-tab electrode assembly 6 along its long side. The detection sliding module 421 drives the support rod 422 to move along the direction perpendicular to the long side of the full-tab electrode assembly 6. The imaging module 423 takes pictures of the edge position of the negative electrode sheet on each full-tab electrode assembly 6 on the clamping module 412, i.e., along the short side, and compares the images with the initial mark of the imaging module 423. The position of the negative electrode plate is compared with the edge position. If there is a positional deviation, the displacement in the short side direction is guided and compensated by driving the positioning sliding module 411. After the displacement compensation is completed, the full tab electrode group 6 is positioned and corrected. Then, the clamping module 412 is opened to release the clamping of the full tab electrode group 6. The second transfer gripping mechanism 3 then grips the full tab electrode group 6 on the clamping module 412 and transports it to the tray 52 on the circulating fixture 5. Then, the pressure block 54 on the spinning spring cylinder 53 rotates and presses the large surface of the full tab electrode group 6, completing the transfer and secondary positioning of the full tab electrode group 6. At this time, the relative position of the full tab electrode group 6 on the circulating fixture 5 is accurate and meets the requirements of the process.
[0037] In summary, this embodiment achieves non-contact guidance and correction of the full-tab electrode assembly 5 through the positioning and correction mechanism 4, fundamentally eliminating the problem of electrode flipping or bulging wrinkles caused by secondary positioning of the full-tab electrode assembly 5, and greatly improving the product yield.
