Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0057] like Figure 1 As shown, the tab bending mechanism provided in this embodiment includes: a pressing device 100, a diagonal bracing device 200, a first bending device 300, a second bending device 400, and a mounting carrier 500; the pressing device 100 is located above the mounting carrier 500, the first bending device 300 is connected to the pressing device 100, and the first bending device 300 and the pressing device 100 are driven independently, and the second bending device 400 is located to the side of the mounting carrier 500.

[0058] The mounting carrier 500 is used to mount the product 10 with tabs 13, and the mounting carrier 500 forms a processing space 510. The diagonal bracing device 200, the first bending device 300, and the second bending device 400 bend the tabs 13 of the product 10 within the processing space 510. The pressing device 100 is configured to press the product 10 firmly to prevent displacement of the product 10 during the bending process of the tabs 13. The diagonal bracing device 200 is configured to extend into the processing space 510 to support the tabs 13. Ear 13 provides a support point to ensure that ear 13 can be bent; the first bending device 300 is configured to extend into the processing space 510 to push ear 13 to bend by 90 degrees, so that ear 13 forms a bending part and a fixing part that are perpendicular to each other. The fixing part is the part of ear 13 supported by the diagonal bracing device 200, and the bending part is the part that is bent by the first bending device 300. The second bending device 400 is configured to extend into the processing space 510 to push the bending part to bend relative to the fixing part, thereby bending ear 13 by 180 degrees.

[0059] The tab bending mechanism provided in this embodiment first installs the product 10 with tabs 13 using the mounting carrier 500, clamps the product 10 using the pressing device 100 and the diagonal bracing device 200, and then pushes the tabs 13 on the product 10 to bend 90 degrees using the first bending device 300, so that the tabs 13 form mutually perpendicular bending parts and fixing parts. Then, the bending part is pushed to bend relative to the fixing part by the second bending device 400, thereby bending the tabs 13 180 degrees. Since each component is relatively independent and can be extended into the processing space 510 to bend the tabs 13, the tabs 13 can be bent in a small space, which alleviates the technical problem that traditional bending mechanisms in the prior art cannot complete the bending of the tabs 13 in a confined space.

[0060] Regarding the structure and shape of the mounting vehicle 500, specifically:

[0061] like Figure 2 As shown, the mounting carrier 500 is a frame structure. The product 10 is installed inside the mounting carrier 500, and a portion of the mounting carrier 500 is hollow to form a processing space 510. Specifically, the mounting carrier 500 has a through hole in the vertical direction, and the side wall forming the through hole surrounds the processing space. When the product 10 with tabs 13 is installed in the mounting carrier 500, the tabs 13 are located in the processing space so that the diagonal bracing device 200, the first bending device 300, and the second bending device 400 can support and bend the tabs 13.

[0062] The mounting carrier 500 includes an upper plate 511 and a base 512. The upper plate 511 is mounted on the base 512. The middle portion of the base 512 is recessed to form a receiving groove. The receiving groove provides a receiving space between the upper plate 511 and the base 512. The product 10 with tabs 13 is placed in the receiving space, thereby mounting the product 10 on the mounting carrier 500. The product 10 includes an interconnected battery cell 11 and a circuit board 12. Tabs 13 are connected to the bottom of the circuit board 12. Some tabs 13 are connected to the circuit board 12, while others protrude from the side of the circuit board 12. A first bending device 300 and a second bending device 400 bend the protruding tabs 13 from the circuit board 12.

[0063] Regarding the structure and shape of the pressing device 100, specifically:

[0064] like Figure 3 , Figure 4 As shown, the pressing device 100 includes a pressing drive component 110, a cell pressing block 120 and a circuit board pressing block 130. The pressing drive component 110 can be configured as a drive motor, a drive hydraulic cylinder or a drive air cylinder. Preferably, the pressing drive component 110 is configured as a drive air cylinder, which is easier to control and occupies less space.

[0065] The pressing drive component 110 is connected to the cell pressing block 120 and the circuit board pressing block 130. The pressing drive component 110 drives the cell pressing block 120 and the circuit board pressing block 130 to move together. The downward pressure generated by the pressing drive component 110 is applied to the cell 11 and the circuit board pressing block 130 through the cell pressing block 120 and the circuit board pressing block 130 respectively.

[0066] The pressing drive component 110 is specifically a pressing drive cylinder. The drive rod of the pressing drive cylinder is connected to a pressing drive connecting plate 111. The pressing drive connecting plate 111 is connected to the cell pressing block 120 and the circuit board pressing block 130. The driving force generated by the pressing drive component 110 drives the pressing drive connecting plate 111 to move. Since the cell pressing block 120 and the circuit board pressing block 130 are both connected to the pressing drive connecting plate 111, the cell pressing block 120 and the circuit board pressing block 130 can be lifted and moved.

[0067] The pressing device 100 also includes a pressing pin 140; the upper plate 511 of the mounting carrier 500 has a through hole, the pressing pin 140 passes through the through hole and is connected to the battery cell 11, the pressing pin 140 can move in the through hole, the top end of the pressing pin 140 protrudes from the upper surface of the mounting carrier 500, the battery cell pressing block 120 can press the pressing pin 140, so that the battery cell pressing block 120 applies downward pressure to the battery cell 11 through the pressing pin 140, thereby restricting the movement of the battery cell 11 relative to the mounting carrier 500.

[0068] In an optional embodiment, the pressing device 100 further includes an elastic connector 150; one end of the elastic connector 150 is connected to a pressing drive connecting plate 111 connected to the pressing drive member 110, and the other end of the elastic connector 150 is connected to the cell pressing block 120. The elastic connector 150 is used to make the cell pressing block 120 have a tendency to move towards the pressing pin 140, so that the cell pressing block 120 and the pressing pin 140 are in elastic contact. The cell pressing block 120 has a certain amount of floating, so that after the cell pressing block 120 contacts the pressing pin 140, the pressing drive member 110 can still continue to drive the circuit board pressing block 130 and the cell pressing block 120 to continue to move until the circuit board pressing block 130 presses the circuit board 12. The elastic contact can also effectively prevent the pressing pin 140 from rigidly contacting the cell 11 and damaging the cell 11.

[0069] Regarding the structure and shape of the first bending device 300, specifically:

[0070] like Figure 3 , Figure 4 As shown, the first bending device 300 includes a bending drive component 310 and a bending roller 320. The bending drive component 310 can be configured as a drive motor, a drive hydraulic cylinder or a drive air cylinder. Preferably, the bending drive component 310 is configured as a drive air cylinder.

[0071] The bending drive component 310 is connected to the bending roller 320 in a transmission manner. The bending drive component 310 can drive the bending roller 320 to move in the processing space 510 along a direction perpendicular to the tab 13, so that the bending roller 320 can push the tab 13 to bend 90 degrees.

[0072] The bending drive component 310 is specifically a bending drive cylinder. The driving end of the bending drive cylinder is connected to a bending drive connecting plate 311. The bottom of the bending drive connecting plate 311 is connected to multiple bending rollers 320. The driving force generated by the bending drive component 310 drives the multiple bending rollers 320 to move up and down through the bending drive connecting plate 311, thereby pushing the multiple tabs 13 to bend 90 degrees simultaneously.

[0073] It should be noted that the bending roller 320 includes a bending connecting block 321 and a roller body 322. The bending connecting block 321 is made of PEEK insulating material. The top of the bending connecting block 321 is connected to the bending drive connecting plate 311. Connecting plates extend downward from both sides of the bottom end of the bending connecting block 321. The roller body 322 is rotatably connected to the two connecting plates, allowing the roller body 322 to rotate freely. The roller body 322 is made of corrosion-resistant plastic mold steel material.

[0074] The number of bending rollers 320 corresponds one-to-one with the number of tabs 13. A first connecting plate is fixedly installed on the driving end of the bending drive component 310, and multiple bending rollers 320 are correspondingly installed on the first connecting plate, thereby realizing the one-time bending of multiple tabs 13.

[0075] In an optional embodiment, the tab bending mechanism further includes a fixed bracket 600; the fixed bracket 600 is fixedly provided with a mounting plate 610, and the bending drive component 310 and the pressing drive component 110 are respectively installed on opposite sides of the mounting plate 610, thereby installing the bending drive component 310 and the pressing drive component 110, which saves more space.

[0076] Regarding the structure and shape of the second bending device 400, specifically:

[0077] like Figure 5 As shown, the second bending device 400 includes a forward module 410, a lifting module 420, and a bending pusher 430. The lifting module 420 is connected to the bending pusher 430 in a transmission manner. The lifting module 420 is configured to drive the bending pusher 430 to move up and down so that the bending pusher 430 can extend into the processing space 510. Specifically, the lifting module 420 includes a lifting drive component 421, a lifting slide rail 422, and a lifting slider 423. The lifting slider 423 is slidably connected to the lifting slide rail. The lifting drive component 421 is connected to the lifting slider 423 in a transmission manner. The lifting drive component 421 can be a drive motor, a cylinder, or a hydraulic cylinder. The force generated by the lifting drive component 421 drives the lifting slider 423 to move on the lifting slide rail 422. The lifting slider is connected to multiple bending pushers 430, thereby realizing the lifting and lowering movement of multiple bending pushers 430. The multiple bending pushers 430 are correspondingly arranged with multiple tabs 13.

[0078] The forward module 410 is connected to the lifting module 420 via a transmission. The forward module 410 is configured to drive the lifting module 420 to move toward or away from the tab 13, so that the bending push block 430 can push the part to be bent relative to the fixed part to bend it by 180 degrees. Specifically, the forward module 410 includes a forward drive component 411, a forward slide rail 412, and a forward slider 413. The forward drive component 411 is specifically a drive motor, a cylinder, or a hydraulic cylinder. The forward slider 413 is slidably connected to the forward slide rail 412. The lifting slide rail 422 is mounted on the forward slider 413. The driving force generated by the forward drive component 411 drives the forward slider 413 to move, thereby driving the lifting slide rail to move toward or away from the tab 13.

[0079] It should be noted that the bending push block 430 includes a push block connecting block 431 and a push block body 432. The bottom end of the push block connecting block 431 is connected to the forward slider 413 through a connecting plate, and the top end of the push block connecting block 431 is connected to the push block body 432. The push block connecting block 431 is made of PEEK insulating material, and the push block body 432 is made of corrosion-resistant plastic mold steel material.

[0080] Regarding the structure and shape of the diagonal bracing device 200, specifically:

[0081] like Figure 6 As shown, the diagonal bracing device 200 includes a diagonal bracing drive component 210 and a diagonal bracing support block 220; the diagonal bracing drive component 210 is connected to the diagonal bracing support block 220 in a transmission manner, and the diagonal bracing drive component 210 is specifically configured as a drive cylinder, and the diagonal bracing drive component 210 is configured to drive the diagonal bracing support block 220 to extend into the processing space 510 along the moving path to support the tab 13 located at the bottom of the circuit board 12.

[0082] The diagonal brace drive component 210 is specifically a diagonal brace drive cylinder. The drive rod of the diagonal brace drive cylinder is connected to the diagonal brace drive connecting plate 211. Multiple diagonal brace support blocks 220 are connected to the diagonal brace drive connecting plate 211. In order to limit the movement direction of the diagonal brace drive connecting plate 211, a slide rail slider can be used. That is, the diagonal brace drive connecting plate 211 is connected to the slider, and the slider is slidably connected to the slide rail, thereby limiting the movement direction of the diagonal brace drive connecting plate 211. It should be noted that, preferably, the movement direction of the diagonal brace support block 220 has a 120-degree angle with the bottom surface of the pole lug 13, so that when the bending push block 430 pushes the pole lug 13, which is in a 90-degree state, to abut against the diagonal brace support block 220, the pole lug 13 can be in a 120-degree bent state.

[0083] The diagonal brace support block 220 specifically includes a diagonal brace connecting block 221 and a diagonal brace block body 222. One end of the diagonal brace connecting block 221 is connected to the diagonal brace drive connecting plate 211, and the other end of the diagonal brace connecting block 221 is connected to the diagonal brace block body 222. The diagonal brace connecting block 221 is made of PEEK insulating material, and the diagonal brace block body 222 is made of corrosion-resistant plastic mold steel material.

[0084] In addition, the top surface of the inclined support block body 222 has an inclined surface, which is set parallel to the electrode ear, so that the inclined surface of the inclined support block body 222 can abut against the electrode ear 13 and play the role of supporting the electrode ear 13.

[0085] Specifically, the moving path of the inclined support block 220 is set at an angle to the circuit board 12. The inclined support block 220 has a supporting inclined surface, which abuts against the tab 13 located at the bottom of the circuit board 12, thereby supporting the part of the tab 13 connected to the circuit board 12.

[0086] The specific working steps of the tab bending mechanism are as follows:

[0087] It is important to note that Figures 7-13 The arrows in the diagram indicate the direction of movement.

[0088] Pressing steps: as follows Figure 7 As shown, the pressing drive component 110 drives the circuit board pressing block 130 and the battery cell pressing block 120 to press the circuit board 12 and the battery cell 11 respectively.

[0089] 90-degree bend steps: as follows Figure 8 As shown, the bending drive component 310 drives the bending roller 320 to extend into the processing space 510 and press down the electrode tab 13, bending the electrode tab 13 to 90 degrees to form the part to be bent and the fixed part.

[0090] 180-degree pre-bend preparation steps: as follows Figure 9 As shown, the bending drive component 310 drives the bending roller 320 to rise, causing the bending roller 320 to move out of the processing space 510.

[0091] 180-degree pre-bending steps: as follows Figure 10 As shown, the forward module 410 and the lifting module 420 cooperate to allow the bending push block 430 to enter the processing space 510, and drive the bending push block 430 to push the part to be bent, so that the part to be bent is bent and clamped between the inclined support block 220 and the bending push block 430. At this time, the part to be bent is in a 120-degree bending state.

[0092] Preparation steps for 180-degree bend: Figure 11 As shown, the diagonal brace support block 220 and the bending push block 430 are removed.

[0093] 180-degree bend forward push steps: as follows Figure 12As shown, the bending pusher 430 moves forward to push the part to be bent to bend by 180 degrees, forming the tab 13 that has been bent by 180 degrees.

[0094] 180-degree bend and ascent steps: as follows Figure 13 As shown, the bending pusher 430 moves upward to push the tab 13, pressing the tab 13 which is bent 180 degrees.

[0095] The electrode bending mechanism provided by this utility model can bend the electrode 13 in a small space, and can stably bend relatively hard materials, and can bend multiple electrodes 13 simultaneously.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
