[0002] Tabs are generally attached to both sides of the wound edge of the electrode sheet and are used for the conduction of the battery cell. Before the wound battery cell is formed into a battery, the tabs are usually folded up and placed close to the end face of the wound electrode sheet to facilitate the subsequent forming process of the battery.

[0003] In existing technologies, the tabs are generally formed by manual pressing. This method is not only inefficient, but also prone to inconsistent quality due to human factors.

[0042] Example 1:

[0043] Please see the appendix Figure 1 The camera shutter-type battery tab retraction and forming mechanism 10 in this embodiment includes a mechanism mounting frame 100, a tab retraction drive assembly 200 disposed on the mechanism mounting frame 100, and a camera shutter-type tab retraction assembly 300 connected to the tab retraction drive assembly 200. The mechanism mounting frame 100 is used for the installation and fixing of various components in the mechanism, and for connecting the entire mechanism to the battery tab retraction and forming device. The tab retraction drive assembly 200 provides the power source for retracting the battery tabs. The components in the camera shutter-type tab retraction assembly 300 used for tab retraction and forming are arranged in a ring array, and the tabs are retracted and formed through reciprocating motions that converge and diverge around the center of the ring array. Specifically, the retraction forming component 341, through reciprocating motion around the center of the ring array, can form a converged state for tab retraction and a divergent state that facilitates tab passage.

[0044] Please refer to the appendix for further details. Figure 2 The electrode retraction drive assembly 200 includes a rotation drive 210, a transmission gear 220 connected to the rotation drive 210, and a driven gear 230 meshing with and transmitting power to the transmission gear 220. When the rotation drive 210 is running, it drives the transmission gear 220 to rotate, thereby driving the driven gear 230 meshing with it to rotate. By simply connecting the camera shutter type electrode retraction assembly 300 to the driven gear 230, the entire linkage of the camera shutter type electrode retraction assembly 300 can be realized. Preferably, in order to realize the change between the convergence and divergence states of the retraction forming part 341 in the camera shutter type electrode retraction assembly 300, the rotation drive 210 is selected as a motor drive that can rotate in the positive direction.

[0045] Please refer to the appendix for further details. Figure 2 The camera shutter type electrode retraction assembly 300 includes a component limiting mounting sleeve 310 disposed on the mechanism mounting frame 100, a rotating dial 320 connected to the driven gear 230 and disposed within the component limiting mounting sleeve 310, a limiting groove 330 connected to the component limiting mounting sleeve 310, and a camera shutter type electrode retraction unit 340 disposed between the rotating dial 320 and the limiting groove 330, which retracts and shapes the battery electrode by reciprocating motion around the center line of the rotating dial 320.

[0046] Please refer to the appendix for further details. Figure 3 The rotary dial 320 includes a dial body 321 and multiple dial limiting grooves 322 formed on the dial body 321 and arranged in a ring array around the center line of the dial body 321. Please refer to the appendix for further details. Figure 4 The limiting slot 330 includes a slot body 331, multiple track grooves 332 corresponding to the dial limiting slots 322 and formed on the slot body 331, and retracting forming holes 333 corresponding to the center line of the rotating dial 320 and formed on the slot body 331. Further, the camera shutter-type electrode retraction unit 340 includes multiple electrode retraction forming modules 340a corresponding to the dial limiting slots 322 and track grooves 332 and arranged in a ring array around the center line of the rotating dial 320; please refer to the appendix for further details. Figure 5 The tab retraction molding module 340a includes a retraction molding component 341 for retracting and molding the battery cell tabs, a cam driven bearing 342 connected to one side of the retraction molding component 341 and movably disposed on a dial limiting groove 322, and a guide key 343 connected to the opposite side of the retraction molding component 341 and movably disposed on a track groove 332. Preferably, the retraction molding component 341 includes a molding connection portion 3411 for connecting with other components, and a wedge-shaped molding portion 3412 disposed on the molding connection portion 3411 for retracting and molding the tabs.

[0047] The limiting slot 330 is fixed on the component limiting mounting sleeve 310. When the rotating dial 320 rotates under the drive of the driven gear 230, the tab forming module 340a moves towards or away from the center line of the rotating dial 320 under the drive of the rotating dial 320 and the limiting action of the track groove 332. Since the multiple tab forming modules 340a are designed to be arranged in a ring array around the center line of the rotating dial 320, when they move, they can form a converged state with a smaller distribution diameter or a divergent state with a larger distribution diameter, thereby realizing the forming process of the battery cell tabs. Preferably, the length direction of the track groove 332 and the length direction of the dial limiting groove 322 form an angle α, and the angle α > 0°. That is, the track groove 332 and the dial limiting groove 322 are designed to be non-parallel, which can effectively increase the stroke distance between the track groove 332 and the dial limiting groove 322 to meet the forming of battery cells of different sizes.

[0048] In this embodiment, the camera shutter-type battery cell tab retraction and forming mechanism 10 and the camera shutter-type tab retraction assembly 300 achieve tab retraction and forming through multiple retraction and forming components 341 arranged in a ring array, converging and diverging around the center of the ring array. The retraction and forming components 341, through reciprocating movement around the center of the ring array, can form a converged state for retraction of the tab and a divergent state for easy passage of the tab. Compared with the manual pressing and forming process, using automated mechanical equipment to retract and form the tab can not only effectively improve the efficiency of tab retraction and forming, but also meet the standardization requirements of tab retraction and forming, thereby effectively improving the quality of the battery cell after forming.

[0049] Example 2:

[0050] Please see the appendix Figure 1 The camera shutter-type battery cell tab retraction forming mechanism 10 in this embodiment is the same as that in Embodiment 1, including a mechanism mounting frame 100, a tab retraction drive assembly 200 disposed on the mechanism mounting frame 100, and a camera shutter-type tab retraction assembly 300 connected to the tab retraction drive assembly 200; the main difference is:

[0051] The camera shutter-type battery cell tab retraction and forming mechanism 10 in this embodiment also includes a tab pre-retraction component 400 corresponding to the camera shutter-type tab retraction component 300, which is used to pre-form the tab before the camera shutter-type tab retraction component 300 retracts and forms the tab, so as to further improve the quality of tab forming.

[0052] Please refer to the appendix for further details. Figure 6The electrode pre-retraction assembly 400 includes a pre-retraction drive guide unit 410 and a pre-retraction forming unit 420 corresponding to the electrode forming portion of the camera shutter-type electrode retraction assembly 300 and connected to the pre-retraction drive guide unit 410. Please refer to the appendix for further details. Figure 7 The pre-shrinking drive guide unit 410 includes a pre-shrinking drive module 411, a transmission guide module 412 connected to the pre-shrinking drive module 411, and a fixture connecting seat 413 connected to the end of the transmission guide module 412 away from the pre-shrinking drive module 411. The pre-shrinking forming unit 420 includes a fixture mounting plate 421 disposed on the fixture connecting seat 413, and a pre-shrinking forming fixture 422 disposed on the fixture mounting plate 421 and adapted to the two poles of the battery cell. Preferably, the pre-shrinking forming fixture 422 includes a cylindrical fixture body 4221 and a tab pre-forming groove 4222 formed on the end of the cylindrical fixture body 4221 away from the fixture mounting plate 421, as shown in the attached figure. Figure 8 As shown.

[0053] The pre-shrinking drive module 411 is activated, causing the fixture connecting seat 413, which is connected to the end of the transmission guide module 412, to move closer to the battery cell tab. This causes the pre-shrinking forming fixture 422, located on the fixture connecting seat 413, to move closer to the battery cell tab for pre-shrinking forming. To ensure the quality of the pre-shrinking forming, preferably, the pre-shrinking forming fixture 422 is correspondingly positioned to correspond to the tab forming part of the camera shutter-type tab retracting assembly 300. Therefore, pre-formed through holes are provided at the center lines of the driven gear 230 and the rotating dial 320 in the camera shutter-type tab retracting assembly 300 to facilitate the passage of the pre-shrinking forming fixture 422.

[0054] The camera shutter-type battery cell tab retraction and forming mechanism 10 in this embodiment is further designed based on embodiment 1, which can further effectively meet the standardization requirements of tab retraction and forming, thereby further effectively improving the quality of the battery cell after forming.

[0055] Example 3:

[0056] Please see the appendix Figure 9 and 10The camera shutter-type battery electrode tab retraction and forming device in this embodiment includes a device frame 20, end face moving mechanisms 30 disposed on both sides of the device frame 20, a camera shutter-type battery electrode tab retraction and forming mechanism 10 disposed on the end face moving mechanism 30 as described in Embodiment 1 or 2, and a battery cell fixing mechanism 40 disposed between the end face moving mechanisms 30; wherein, the device frame 20 is used for the installation and fixing of each mechanism in the device, the end face moving mechanism 30 is used to drive the camera shutter-type battery electrode tab retraction and forming mechanism 10 to move closer to or away from the two electrodes of the battery cell, the camera shutter-type battery electrode tab retraction and forming mechanism 10 is used to retract and form the battery cell tabs, and the battery cell fixing mechanism 40 is used for fixing and placing the battery cell.

[0057] The end face moving mechanism 30 includes a transfer drive assembly 500 disposed on one side of the equipment frame 20, and a transfer linkage assembly 600 connected to the transfer drive assembly 500 and disposed on the equipment frame 20; preferably, the transfer drive assembly 500 includes a transfer drive member 510 disposed on one side of the equipment frame 20, and a synchronous belt conveyor unit 520 connected between the transfer drive member 510 and the transfer linkage assembly 600; the transfer linkage assembly 600 includes a transfer slide rail assembly 610 disposed on the equipment frame 20, a linkage screw unit 620 connected to the synchronous belt conveyor unit 520 and mounted above the transfer slide rail assembly 610, and a forming mechanism mounting base 630 connected to the linkage screw unit 620 and slidably disposed on the transfer slide rail assembly 610. Preferably, the camera shutter-type battery cell tab forming mechanism 10 is connected to the forming mechanism mounting base 630 and is disposed opposite to the two poles of the battery cell, which can simultaneously perform forming processing on the two poles of the battery cell, thereby further and effectively improving the efficiency of tab and battery cell forming.

[0058] When the transfer drive 510 is activated, it drives one end of the synchronous belt conveyor unit 520 to rotate, which in turn drives the linkage screw unit 620 connected to the other end of the synchronous belt conveyor unit 520 to rotate. This, in turn, drives the forming mechanism mounting base 630, which is threadedly connected to the screw in the linkage screw unit 620, to move along the length of the screw with the assistance of the transfer slide rail group 610. This causes the camera shutter-type battery cell tab retraction and forming mechanism 10, which is located on the forming mechanism mounting base 630, to move closer to or away from the two poles of the battery cell, and to perform retraction and forming processing on the battery cell tabs.

[0059] Please see the appendix Figure 10 The cell fixing mechanism 40 includes a cell mounting base 700 mounted on the equipment frame 20, and a cell clamping assembly 800 corresponding to and movably mounted above the cell mounting base 700. When the cell is placed on the cell mounting base 700 and its position is adjusted, the cell clamping assembly 800 presses down to clamp and fix the cell, so as to prevent the cell from shifting during the tab forming process, thereby further and effectively ensuring the quality of the tab and the cell after forming.

[0060] The camera shutter-type battery cell tab forming device in this embodiment is assembled from the camera shutter-type battery cell tab forming mechanism 10, the end face moving mechanism 30, and the battery cell fixing mechanism 40 in embodiment 1 or 2. It can automatically form the tabs at both ends of the battery cell, which can not only effectively improve the efficiency of tab forming, but also effectively improve the quality of the battery cell after forming.

[0061] As can be seen from the technical solutions of the above embodiments, the present invention provides a camera shutter-type battery cell tab retraction and forming mechanism, which can not only effectively improve the efficiency of tab retraction and forming, but also meet the standardization requirements of tab retraction and forming, thereby effectively improving the quality of the battery cell after forming. The present invention also provides equipment using this camera shutter-type battery cell tab retraction and forming mechanism, which can automatically retract and form the tabs at both ends of the battery cell, effectively improving both the efficiency of tab retraction and forming and the quality of the battery cell after forming.

[0062] In the description of this invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0063] Although the description of the invention has been given in conjunction with the specific embodiments described above, it will be apparent to those skilled in the art that many substitutions, modifications, and variations can be made based on the foregoing. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
