[0023] Reference Figure 1-2 The battery cell tab shaping mechanism includes a frame 100, a shaping plate 200, a fixing plate 300, a slide rail slider assembly 700, and a first elastic element 400.

[0024] The frame 100 is fixedly installed on a workstation for material processing, such as battery cell processing. The shaping plate 200 is slidably mounted on the frame 100 in the horizontal direction, and the fixing plate 300 is slidably mounted on the frame 100 in the vertical direction. That is, the sliding direction of the shaping plate 200 relative to the frame 100 is perpendicular to the sliding direction of the fixing plate relative to the frame 100.

[0025] A guide inclined surface 210 is provided on one side of the shaping plate 200, and the guide inclined surface 210 is inclined. A cam follower 310 is rotatably mounted on the top side of the fixing plate 300. The cam follower 310 has a roller structure. The outer periphery of the cam follower 310 abuts against the guide inclined surface 210.

[0026] The first elastic element 400 is a first helical spring, with hooks formed at both ends. Connecting posts are installed on both the frame 100 and the shaping plate 200, and through holes are provided on the connecting posts. The hooks can be sleeved on the connecting posts, with the ends of the hooks inserted into the through holes, so that the two ends of the first helical spring can be detachably installed on the frame 100 and the shaping plate 200, respectively. The contraction force of the first helical spring can pull the shaping plate 200, so that the cam follower 310 always remains in contact with the guide inclined surface 210 of the shaping plate 200. A shaping block 230 is installed on the front side of the shaping plate 200. The shaping block 230 is L-shaped and has a slot 220 at one end. A bolt passes through the slot 220 and is also inserted into the shaping plate 200. This allows the shaping block 230 to be detachably connected to the shaping plate 200 by the bolt. When the bolt is loosened, the bolt shank can slide in the slot 220 to adjust the front and rear position of the shaping plate 200. Then, by tightening the bolt, the bolt head and the nut clamp the shaping block 230 and the shaping plate 200, fixing the shaping block 230 to the shaping plate 200. In other embodiments, the first elastic element 400 may also be a first elastic band, with its two ends respectively threaded and tied to the frame 100 and the shaping plate 200, so that the contraction force of the first elastic band can pull the shaping plate 200, so that the cam follower 310 always remains in contact with the guide inclined surface 210 of the shaping plate 200.

[0027] When the fixed plate 300 is driven to move up and down by a drive component such as a cylinder, hydraulic cylinder, or electric telescopic cylinder, the cam follower 310 can be driven to move downward, thereby pushing the shaping plate 200 to move forward against the elastic force of the first elastic element 400, and driving the shaping block 230 to move forward to straighten the battery cell tabs; it can also drive the cam follower 310 to move upward, thereby releasing the shaping plate 200 and allowing the shaping plate 200 to return to its initial position under the elastic force of the first elastic element 400. In both processes, the cam follower 310 rolls on the guide inclined surface 210, thereby making the transmission between the fixed plate 300 and the shaping plate 200 more stable and reliable.

[0028] Furthermore, the battery cell tab shaping mechanism also includes a shaping swing arm 500, a shaping connecting rod 510, a shaping cam 600, and a second elastic element 610. The shaping swing arm 500 and the shaping cam 600 are both rotatably mounted on the frame 100. A rolling wheel 501 is rotatably mounted on one side of the middle portion of the shaping swing arm 500, and the outer periphery of the rolling wheel 501 abuts against the outer periphery of the shaping cam 600. The second elastic element 610 is a second helical spring, with one end mounted on the frame 100 and the other end mounted on the shaping swing arm 500. The contractile force provided by the second helical spring can pull the shaping swing arm 500, ensuring that the outer periphery of the rolling wheel 501 on the shaping swing arm 500 always abuts against the outer periphery of the shaping cam 600. In other embodiments, the second elastic element 610 may also be a second elastic band, with both ends of the second elastic band threaded and tied to the frame 100 and the shaping arm 500 respectively, so that the contraction force of the second elastic band can pull the shaping arm 500, so that the outer periphery of the rolling wheel 501 on the shaping arm 500 always abuts against the outer periphery of the shaping cam 600.

[0029] The end of the shaping arm 500 furthest from the rotating end is rotatably connected to one end of the shaping link 510. The connection between the second helical spring and the shaping arm 500 is located between the shaping link 510 and the rolling wheel 501. The end of the shaping link 510 furthest from the shaping arm 500 is rotatably connected to the bottom of the fixed plate 300. When the shaping cam 600 is driven to rotate, it can push the shaping arm 500 to swing, thereby pulling the fixed plate 300 up and down through the shaping link 510, thus realizing the forward and backward movement of the shaping plate 200, and aligning the electrodes of the battery cell in the work position. After aligning the electrodes, it can prevent the electrodes from tilting to one side and interfering with the actuator on that side, thus preventing damage to the battery cell electrodes. Furthermore, by using the cam follower 310 to move the shaping plate 200, the impact on the electrode tabs is minimized when the shaping block 230 pushes them, thus protecting the electrode tabs. Moreover, through the rational design of the outer peripheral curve of the shaping cam 600, the shaping block 230 decelerates during the electrode tab pushing process, achieving a gentle shaping function. This means the shaping block 230's action of straightening the battery cell is relatively smooth, less likely to damage the electrode tabs, and easier to adjust. In addition, using the shaping cam 600 as the drive source allows it to share a unified power source with other actuators in battery cell processing, adjusting the action connection of the mechanisms to a very short time interval, thereby greatly improving time utilization. Furthermore, the alternating action of the cam curve of the shaping cam 600 avoids the problem of misaligned actions caused by inconsistent power sources between actuators.

[0030] In other embodiments, the shaping cam 600 and the second elastic element 610 may not be provided. Instead, a motor or other driving component can be used to directly drive the shaping swing arm 500 to swing, thereby pulling the fixed plate 300 up and down through the shaping connecting rod 510, and thus realizing the forward and backward movement of the shaping plate 200 to push and align the electrodes of the battery cell at the work station.

[0031] The sliding of the shaping plate 200 relative to the frame 100 and the sliding of the fixing plate 300 relative to the frame 100 are both achieved by the slide rail slider assembly 700.

[0032] Specifically, the slide rail and slider assembly 700 includes a guide slide rail 710 and a guide slider 720. A screw is threaded through the guide slide rail 710 and connected to the frame 100, allowing the guide slide rail 710 to be detachably mounted on the frame 100. The guide slider 720 has a through-hole groove that allows the guide slide rail 710 to extend into, and the guide slide rail 710 can slide within the groove, thus enabling relative sliding between the guide slide rail 710 and the guide slider 720.

[0033] The guide rail 710 has grooves 711 on both sides, and the length direction of the grooves 711 is the same as the sliding direction of the guide slider 720 relative to the guide rail 710. Both sides of the groove have protrusions 721, the cross-section of which matches the cross-section of the groove 711. Both the cross-section of the protrusions 721 and the cross-section of the groove 711 are semi-circular, facilitating the matching of the protrusions 721 and the grooves 711 while preventing the guide slider 720 from disengaging from the guide rail 710 in the direction perpendicular to the sliding direction, thus improving the relative sliding stability and reliability of the guide rail 710 and the guide slider 720.

[0034] The frame 100 is provided with two slide rail slider assemblies 700. The guide slider 720 of one of the slide rail slider assemblies 700 is detachably connected to the shaping plate 200 and the relative sliding direction is horizontal. If a screw threadedly connected to the guide slider 720 is provided on the shaping plate 200, the shaping plate 200 can be removed or installed by loosening or tightening the screw. After the shaping plate 200 is installed on the guide slider 720, the shaping plate 200 can slide stably relative to the frame 100.

[0035] Another slide rail slider assembly 700 has a guide slider 720 that is detachably connected to the fixed plate 300 and slides vertically relative to it. If a screw threadedly connected to the guide slider 720 is provided on the fixed plate 300, the fixed plate 300 can be removed or installed by loosening or tightening the screw. After the fixed plate 300 is installed on the guide slider 720, the fixed plate 300 can slide stably relative to the frame 100.

[0036] Furthermore, at the station for shaping and straightening the tabs of the battery cells, a processing flow can be designed to process two battery cells simultaneously each time. In this embodiment, a shaping linkage 510 can be rotatably connected to two fixed plates 300 respectively. Thus, when the shaping cam 600 is driven to rotate, the shaping linkage 510 can drive the two fixed plates 300 and their corresponding cam follower 310, shaping plate 200 and shaping block 230 to move synchronously. This allows for simultaneous straightening of the tabs on two battery cells, improving battery cell processing efficiency.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
