[0035] According to an embodiment of the present application, a bending mechanism is provided. As shown in FIG. 1, the bending mechanism comprises a first base 1, a first abutting portion 11, a limiting portion 12, a first connecting portion 13, a first bending assembly 2, a first connecting piece 21, a first bending piece 22, a first region 221, a second region 222, a second connecting portion 225, a bending portion 223, a pivot 224, a second bending assembly 3, a second bending piece 31, a supporting portion 311, a second abutting portion 312, a second connecting piece 32, an elastic reset piece 4, a battery 5, a tab 51, a cap 52, a cup 6, a cam disc 8, a first guide groove 81, a second guide groove 82, a first follower 9, a second follower 10, a second base 20, and a rotating disc 30. Figures 1 to 3As shown, the bending mechanism comprises a first base 1, a first bending assembly 2 and a second bending assembly 3. The first bending assembly 2 comprises a first connecting piece 21 and a first bending piece 22, the first connecting piece 21 is movably connected to the first base 1, and the first bending piece 22 is rotatably connected to the first connecting piece 21. The second bending assembly 3 comprises a second bending piece 31, which is arranged on the first base 1, and the second bending piece 31 is arranged opposite to the first bending piece 22. Wherein, the first connecting piece 21 can drive the first bending piece 22 to move away from the second bending piece 31, and the first bending piece 22 can rotate to avoid the workpiece to be bent.

[0036] As shown in Figure 1 and Figure 2 In this example, the first connecting piece 21 can drive the first bending piece 22 to move away from the second bending piece 31, and the first bending piece 22 can also rotate, so as to further increase the space between the first bending piece 22 and the second bending piece 31, so as to facilitate the feeding of the workpiece to be bent.

[0037] In this example, there is a gap between the first bending piece 22 and the second bending piece 31, and the workpiece to be bent is placed between the first bending piece 22 and the second bending piece 31. Then, the first bending piece 22 and the second bending piece 31 can move close to each other, for example, the first connecting piece 21 can drive the first bending piece 22 to move towards the second bending piece 31, at the same time, the first bending piece 22 rotates, so that the bending part 223 of the first bending piece 22 can rotate towards the second bending piece 31, so that the second bending piece 31 can abut against one side of the workpiece to be bent, and the bending part 223 can abut against the other side of the workpiece to be bent, and push the workpiece to be bent. After the workpiece to be bent is bent, the first bending piece 22 and the second bending piece 31 can move away from each other, and the first bending piece 22 can rotate, for example, the bending part 223 rotates away from the second bending piece 31, so as to further increase the space between the first bending piece 22 and the second bending piece 31, so as to facilitate the feeding of the workpiece to be bent next time.

[0038] Figure 1 As shown, in this example, the first bending assembly 2 further comprises a rotating shaft 224, which is rotatably arranged on the first bending piece 22, and the first bending piece 22 is rotatably connected to the first connecting piece 21 through the rotating shaft 224.

[0039] In this example, the first base 1 can be provided with a sliding rail, and the first connecting piece 21 can be a sliding block, which is slidingly installed on the sliding rail, so as to drive the first bending piece 22 to move along the sliding rail, so as to drive the first bending piece 22 to move close to or away from the second bending piece 31.

[0040] As shown in Figure 2 and Figure 3 , in this example, the workpiece to be bent can be the tab 51 of the battery 5, and the end of the tab 51 is welded with a cap 52. The tab 51 is bent by the first bending member 22 and the second bending member 31, so as to facilitate the subsequent buckling of the cap 52 into the shell of the battery 5. Of course, the workpiece to be bent can also be other types of components, which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0041] In one example, as shown in Figures 1 to 3 , the first base 1 is provided with a first abutting portion 11, which can abut against one side of the first bending member 22, and when the first bending member 22 moves away from the second bending member 31, the first abutting portion 11 can drive the first bending member 22 to rotate forward.

[0042] As shown in Figure 1 and Figure 2 , in this example, one side of the first bending member 22 can abut against the first abutting portion 11, and when the first connecting member 21 drives the first bending member 22 to move away from the second bending member 31, the first bending member 22 can be driven to rotate forward around the rotation shaft 224 due to the abutment of one side of the first bending member 22. For example, when the first bending member 22 is bent in cooperation with the second bending member 31, the first bending member 22 is vertically arranged. When the first connecting member 21 drives the first bending member 22 to move away from the second bending member 31, the first bending member 22 can be rotated forward to be horizontally arranged. The forward rotation can be counterclockwise rotation. The position of the first abutting portion 11 abutting against the first bending member 22 is located on one side of the rotation shaft 224, i.e., when the first bending member 22 is horizontally arranged, the first abutting portion 11 abuts against the upper surface of the first bending member 22 and is located on the left side of the rotation shaft 224.

[0043] In this example, the first abutting portion 11 can be a roller shaft, which is rotationally connected to the first base 1, and the side surface of the rotation shaft 224 can abut against the surface of the first bending member 22. The first abutting portion 11 can rotate relative to the first bending member 22, so as to improve the smoothness of the rotation of the first bending member 22.

[0044] In one example, as shown in Figures 1 to 3 , the bending mechanism further comprises a resilient reset member 4, which is connected to the first bending member 22, and when the first bending member 22 moves towards the second bending member 31, the resilient reset member 4 can drive the first bending member 22 to rotate reversely.

[0045] As shown in Figures 1 to 3As shown, the elastic reset member can act on the first bending member 22, and when the first bending member 22 moves towards the second bending member 31, the elastic reset member 4 can drive the first bending member 22 to rotate reversely, so that the bending part 223 can rotate reversely towards the second bending member 31, and the bending member can be folded with the second bending member 31. The reverse rotation can be clockwise rotation.

[0046] In this example, one end of the elastic reset member 4 is connected to the first bending member 22, and the other end is connected to the first base 1. As shown, Figure 1 The first base 1 is provided with a first connecting part 13, and the first bending member 22 is provided with a second connecting part 225. One end of the elastic reset member 4 is connected to the first connecting part 13, and the other end is connected to the second connecting part 225.

[0047] For example, the elastic reset member 4 can be a tension spring, and the first connecting part 13 is located on the side of the first bending member 22 facing the second bending member 31. When the first connecting member 21 drives the first bending member 22 to move towards the second bending member 31, the elastic reset member 4 can pull the first bending member 22 to rotate reversely. Alternatively, the elastic reset member 4 can be a compression spring, and the first connecting part 13 is located on the side of the first bending member 22 away from the second bending member 31. When the first connecting member 21 drives the first bending member 22 to move towards the second bending member 31, the elastic reset member 4 can push the first bending member 22 to rotate reversely. The specific arrangement of the elastic reset member 4 can be determined by those skilled in the art according to the actual situation, which is not limited here.

[0048] In this example, the first connecting part 13 can be a hanging rod provided on the first base 1, and the second connecting part 225 can be a hanging rod provided on the first bending member 22. The elastic reset member 4 is provided with hooks at both ends, and the hooks at both ends can be hung on the first connecting part 13 and the second connecting part 225 respectively. This connection method is simple and easy to operate. Of course, the specific structure of the first connecting part 13 and the second connecting part 225 can be determined by those skilled in the art according to the actual situation, which is not limited here.

[0049] In one example, as shown, Figure 2 The first bending member 22 includes a first region 221 and a second region 222, and the first region 221 and the second region 222 are located on both sides of the rotation shaft 224 of the first bending member 22. The first abutting part 11 acts on the first region 221, and the elastic reset member 4 acts on the second region 222.

[0050] In this example, the first bending member 22 is divided into a first region 221 and a second region 222 by a rotation shaft 224. For example, as shown, Figure 3As shown, the first bending piece 22 is vertically arranged when the first bending piece 22 and the second bending piece 31 cooperate to bend the workpiece. The upper side of the rotating shaft 224 is the first area 221, and the lower side of the rotating shaft 224 is the second area 222. The first abutting portion 11 can abut against the first area. The second connecting portion 225 is arranged at the second area 222, i.e., one end of the elastic reset member 4 is connected to the second area 222 of the first bending piece 22. Thus, the first bending piece 22 can rotate while moving, thereby improving the bending efficiency of the bending mechanism.

[0051] That is, the first abutting portion 11 can drive the first bending piece 22 to rotate forward during the movement of the first bending piece 22 away from the second bending piece 31 by the first connecting member 21. The elastic reset member 4 can drive the first bending piece 22 to rotate reversely during the movement of the first bending piece 22 toward the second bending piece 31 by the first connecting member 21.

[0052] In one example, as shown in Figure 1 and Figure 2 The first bending piece 22 is provided with a bending portion 223 adapted to abut against the workpiece to be bent to bend the workpiece to be bent, and the bending portion 223 is located at the second area 222.

[0053] As shown in Figure 1 and Figure 2 In this example, the bending portion 223 of the first bending piece 22 is arranged at the second area 222. The first abutting portion 11 can drive the first bending piece 22 to rotate forward during the movement of the first bending piece 22 away from the second bending piece 31 by the first connecting member 21, and the bending portion 223 rotates in a direction away from the second bending piece 31. The elastic reset member 4 can drive the first bending piece 22 to rotate reversely during the movement of the first bending piece 22 toward the second bending piece 31 by the first connecting member 21, and the bending portion 223 rotates in a direction toward the second bending piece 31.

[0054] In one example, as shown in Figure 1 The first base 1 is further provided with a limiting portion 12 located at one side of the first abutting portion 11, and the limiting portion 12 is adapted to limit the rotation of the first bending piece 22.

[0055] As shown in Figure 1As shown in the example, the first base 1 is further provided with a limiting portion 12 on one side of the first abutting portion 11, and after the first bending piece 22 is positively rotated to the preset position, the limiting portion 12 can abut against the first bending piece 22, so as to avoid the continuous positive rotation of the first bending piece 22, which causes the elastic reset member 4 to fail to smoothly drive the first bending piece 22 to reverse rotation. Wherein, after the first bending piece 22 is positively rotated to the preset position, the limiting portion 12 can abut against the position of the second area 222 of the first bending piece 22.

[0056] In this example, the limiting portion 12 can be a limiting rod, and the limiting rod is installed on the first base 1. Alternatively, the limiting portion 12 can be integrally formed with the first base 1. The specific structure of the limiting portion 12 can be determined by the person skilled in the art according to the actual situation, which is not limited here.

[0057] In one example, as shown in the example, Figures 1 to 3 The second bending piece 31 is movably arranged on the first base 1.

[0058] As shown in the example, Figures 1 to 3 In this example, the second bending assembly 3 further comprises a second connecting piece 32, and the second bending piece 31 is connected to the second connecting piece 32. The second connecting piece 32 is slidingly connected to the first base 1, that is, the second connecting piece 32 can be a sliding block, and the second connecting piece 32 is slidingly installed on a sliding rail, so as to drive the second bending piece 31 to move along the sliding rail, thereby driving the second bending piece 31 to move close to or away from the first bending piece 22.

[0059] In this example, as shown in the example, Figure 1 The second bending piece 31 is provided with a second abutting portion 312, and the second abutting portion 312 can abut against one side of the workpiece to be bent, and the bending portion 223 can push the other side of the workpiece to be bent, so as to bend the workpiece to be bent.

[0060] When bending the workpiece to be bent, the workpiece to be bent is located between the first bending piece 22 and the second bending piece 31, the second connecting portion 225 can drive the second bending piece 31 to move towards the workpiece to be bent, so as to make the second abutting portion 312 abut against one side of the workpiece to be bent to provide a bending fulcrum. And the first connecting piece 21 can drive the first bending piece 22 to move towards the workpiece to be bent, and the elastic reset member 4 can drive the bending piece to rotate towards the workpiece to be bent, so as to make the bending piece abut against the side of the workpiece to be bent away from the second abutting portion 312, and can push the workpiece to be bent, so as to bend the workpiece to be bent. Wherein, in the vertical direction, the bending portion 223 can be located above or below the second abutting portion, so as to enable the bending portion 223 to press and bend the workpiece to be bent.

[0061] For example, if the workpiece to be bent is the tab 51 of battery 5, the second abutting part 312 can abut against the side of the tab 51 away from the cap 52, the bending part 223 can abut against the cap 52, and can push the cap 52 to bend the tab 51.

[0062] In this example, the second bending member 31 is further provided with a support portion 311, which is adapted to support the side of the workpiece to be bent away from the bending portion 223. After the workpiece to be bent is bent to a preset position, the support portion 311 can support the side of the workpiece to be bent away from the bending portion 223, thereby avoiding the first bending member 22 bending the workpiece at too large an angle, and improving the bending accuracy of the first bending member 22 and the second bending member 31.

[0063] like Figure 2 As shown, in this example, the support portion 311 can be an inclined surface provided by the second bending member 31, with one end of the inclined surface being an abutment portion. The bending portion 223 pushes the cap 52 toward the support portion 311 to achieve bending of the tab 51. When the tab 51 is bent to a preset angle, the end of the cap 52 away from the bending portion 223 can contact the support portion 311, and the support portion 311 can provide support and limit the cap 52.

[0064] In one example, a drive component is also included, which is adapted to move the first bending member 22 and the second bending member 31 closer to or further away from each other.

[0065] The first bending member 22 is slidably disposed on the first base 1. The driving component can drive the first bending member 22 to move toward the second bending member 31 to perform a bending operation. The driving component can also drive the first bending member 22 away from the second bending member 31 to increase the space between the first bending member 22 and the second bending member 31, thereby facilitating material loading.

[0066] Alternatively, the second bending member 31 can be slidably disposed on the first base 1. The driving component can simultaneously drive the first bending member 22 and the second bending member 31 to move towards each other so as to get closer to each other. The driving component can also simultaneously drive the first bending member 22 and the second bending member 31 to move away from each other so as to further increase the space between the first bending member 22 and the second bending member 31, thereby facilitating material loading.

[0067] like Figures 3 to 6As shown in the example, the driving assembly further comprises a first follower 9, for example, the first follower 9 can be a cylindrical wheel, and the first follower 9 can be rotatably connected to the first connecting piece 21. The cam disc 8 is provided with a first guide groove 81, the first guide groove 81 can be curvedly arranged, the first follower 9 is embedded in the first guide groove 81 and can move along the first guide groove 81 to drive the first connecting piece 21 to slide along the slide rail, so as to drive the first bending piece 22 to move towards or away from the second bending piece 31.

[0068] As shown in the example, the driving assembly further comprises a first follower 9, for example, the first follower 9 can be a cylindrical wheel, and the first follower 9 can be rotatably connected to the first connecting piece 21. The cam disc 8 is provided with a first guide groove 81, the first guide groove 81 can be curvedly arranged, the first follower 9 is embedded in the first guide groove 81 and can move along the first guide groove 81 to drive the first connecting piece 21 to slide along the slide rail, so as to drive the first bending piece 22 to move towards or away from the second bending piece 31. Figures 3 to 6 As shown in the example, the driving assembly further comprises a second follower 10, for example, the second follower 10 can be a cylindrical wheel, and the second follower 10 can be rotatably connected to the second connecting piece 32. The cam disc 8 is provided with a second guide groove 82, the second guide groove 82 can be curvedly arranged, the second follower 10 is embedded in the second guide groove 82 and can move along the second guide groove 82 to drive the second connecting piece 32 to slide along the slide rail, so as to drive the second bending piece 31 to move towards or away from the first bending piece 22.

[0069] Figure 4 As shown in the example, the first guide groove 81 and the second guide groove 82 are both annular structures, and the second guide groove 82 is located on the inner side of the first guide groove 81. The first guide groove 81 and the second guide groove 82 have a feeding area with a large spacing and a bending area with a small spacing. In the clockwise direction, the spacing between the first guide groove 81 and the second guide groove 82 gradually decreases from the feeding area to the bending area, and the spacing between the first guide groove 81 and the second guide groove 82 gradually increases from the bending area to the feeding area.

[0070] Wherein, the cam disc 8 is located above the first base 1, the first base 1 is installed on the rotating disc 30, and the rotating disc 30 can drive the first base 1 to rotate. That is, in the feeding area, the spacing between the first bending piece 22 and the second bending piece 31 is large, so as to facilitate the feeding of the workpiece to be bent. The first base 1 can be rotated from the feeding area to the bending area, and since the spacing between the first guide groove 81 and the second guide groove 82 gradually decreases from the feeding area to the bending area, the first follower 9 and the second follower 10 can approach each other, thereby driving the first bending piece 22 and the second bending piece 31 to approach each other to bend the workpiece to be bent. Then, the first base 1 can be rotated from the bending area to the feeding area, and since the spacing between the first guide groove 81 and the second guide groove 82 gradually increases from the bending area to the feeding area, the first follower 9 and the second follower 10 can move away from each other, thereby driving the first bending piece 22 and the second bending piece 31 to move away from each other to facilitate feeding in the feeding area.

[0071] ​According to another embodiment of the present application, a bending device is provided. The bending device comprises the bending mechanism as described in the above embodiments.
