[0056] Referring to Figure 1 、 Figure 11 , this embodiment provides a bending mechanism applied to the short FPC of a battery 5, which includes a pre-bending assembly 1, a grasping and alignment correction assembly 2, a battery transplanting and positioning assembly 3, and a vision alignment and bending assembly 4;

[0057] The pre-bending assembly 1 is arranged opposite to the grasping and alignment correction assembly 2. The pre-bending assembly 1 is used to position and clamp the battery 5 and pre-bend the circuit board 6 to be bent on the battery 5.

[0058] The battery transplanting and positioning assembly 3 is radially arranged on one side in the length direction of the pre-bending assembly 1. The grasping and alignment correction assembly 2 is used to grasp the battery 5 from the pre-bending assembly 1 and transfer it to the battery transplanting and positioning assembly 3.

[0059] The vision alignment and bending assembly 4 is arranged opposite to the battery transplanting and positioning assembly 3. The battery transplanting and positioning assembly 3 is used to move the battery 5 to a preset position. The vision alignment and bending assembly 4 is used to take a picture and position the circuit board 6 to be bent on the battery 5 at the preset position, calculate the position deviation, and bend and form the circuit board 6 to be bent.

[0060] In the above embodiments, the bending mechanism is applied to the short FPC of the battery 5, including a pre-bending component 1, a grasping and alignment component 2, a battery transplanting and positioning component 3, and a vision alignment and bending component 4. The short FPC of the battery 5, namely the flexible printed circuit board (Flexible Printed Circuit, abbreviated as FPC), is the circuit board 6 to be bent in the embodiments. The pre-bending component 1 is mainly used to position and clamp the battery 5 and perform a preliminary bend on the circuit board 6 to be bent thereon, laying a foundation for subsequent precise bending; the grasping and alignment component 2 is responsible for transferring the battery 5 that has completed the pre-bending to the battery transplanting and positioning component 3 and performing position alignment during the process to ensure that the battery 5 reaches the next station accurately; the battery transplanting and positioning component 3 is used to move the battery 5 to a preset position and perform position alignment in the X direction to compensate for possible position deviations caused by the previous steps; the vision alignment and bending component 4 calculates the position deviation through photographing and positioning and performs the final high-precision bending and forming.

[0061] The pre-bending component 1, the grasping and alignment component 2, the battery transplanting and positioning component 3, and the vision alignment and bending component 4 are arranged on the same support plate, and there is a certain interval between the four, forming a compact and efficient automated device; the pre-bending component 1, the grasping and alignment component 2, and the battery transplanting and positioning component 3 are in a rectangular structure. The pre-bending component 1 and the grasping and alignment component 2 are arranged opposite to each other, which means they are perpendicular to each other. That is, the pre-bending component 1 is arranged along the X-axis, and the grasping and alignment component 2 is arranged along the Y-axis, enabling the grasping and alignment component 2 to move along the Y-axis direction, thereby realizing the transfer of the battery 5 from the pre-bending component 1 to the battery transplanting and positioning component 3. The battery transplanting and positioning component 3 is radially arranged on one side of the length direction of the pre-bending component 1, and the two are arranged in a straight line or in a staggered parallel arrangement along the X-axis, forming a linear station transfer path, among which Figure 1 due to the influence of the dimensions of each component, the pre-bending component 1 is not arranged according to the actual working state. The vision alignment and bending component 4 and the battery transplanting and positioning component 3 are arranged perpendicular to each other, but the vision alignment and bending component 4 is arranged along the Z-axis direction, which means it can operate in the vertical direction to facilitate the precise positioning and bending and forming of the circuit board 6 to be bent.

[0062] During operation, the pre-bending assembly 1 positions and clamps the battery 5 and completes the preliminary bending. Subsequently, the grasping and deviation-correcting assembly 2 is activated to transfer the pre-bent battery 5 to the battery transplanting and positioning assembly 3, during which position deviation correction is performed. Then, the battery transplanting and positioning assembly 3 moves the battery 5 to a preset position and compensates for the position deviation in the X direction as needed. Finally, after the vision deviation-correcting and bending assembly 4 takes a photo and positions the circuit board 6 to be bent and calculates the position deviation, the battery transplanting and positioning assembly and the grasping and deviation-correcting assembly 2 perform position deviation compensation in the X and Y directions on the circuit board 6 to be bent on the battery 5, and then perform the final high-precision bending and forming. Therefore, through the above-mentioned components, the pre-bending - transfer - photo positioning, position deviation correction and shaping of the circuit board 6 to be bent are automatically completed in sequence, avoiding the tediousness and time consumption of manual operations such as picking, positioning and bending, improving the overall automated production efficiency. At the same time, the preliminary bending shape control, photo positioning and calculation of position deviation can reduce the error accumulation in the subsequent bending process, improve the accuracy of the final bending, thereby improving the product yield, greatly reducing the production fluctuations caused by human factors, and improving the production stability.

[0063] Referring to Figures 1 - 3 、 Figure 11 In one embodiment, the pre-bending assembly 1 includes a first battery positioning device 10, and the first battery positioning device 10 includes a first positioning support frame 101, a first rear positioning cylinder 102, a first front positioning reference block 103, a first side clamping cylinder 104, and a transplanting cylinder 105;

[0064] The first positioning support frame 101 is used to place the battery 5 to be pre-bent. The first front positioning reference block 103 is arranged on one side of the first positioning support frame 101 close to the grasping and deviation-correcting assembly 2. The first rear positioning cylinder 102 is slidably connected to the first positioning support frame 101, and the first rear positioning cylinder 102 is located on the side of the battery 5 away from the first front positioning reference block 103;

[0065] The first side clamping cylinder 104 is slidably connected to the adjacent side of the first positioning support frame 101 where the first front positioning reference block 103 is arranged. The transplanting cylinder 105 is arranged on the first positioning support frame 101, and the transplanting cylinder 105 is arranged opposite to the first rear positioning cylinder 102. The transplanting cylinder 105 is used to drive the movement of the first positioning support frame 101.

[0066] In the above embodiment, the pre-bending assembly 1 includes a first battery positioning device 10, which is further subdivided into a first positioning support frame 101, a first rear positioning cylinder 102, a first front positioning reference block 103, a first side clamping cylinder 104, and a transplanting cylinder 105. Among them, the first positioning support frame 101 is the basic structure of the entire pre-bending assembly 1, consisting of a first upper support plate 1010, a first support rod 1011, and a first lower support plate 1012.

The first upper support plate 1010 is used to install the first rear positioning cylinder 102, the first front positioning reference block 103, and the first side clamping cylinder 104. In addition, a first battery placement plate 106 specifically for placing the battery 5 is provided on the first upper support plate 1010. The first front positioning reference block 103 is fixedly connected to one side of the first positioning support frame 101 close to the grasping and rectifying assembly 2. Its main function is to contact the circuit board 6 to be bent on the battery 5 and provide a stable reference point for the battery 5. The first front positioning reference block 103 and the first rear positioning cylinder 102 are arranged opposite to each other on both sides of the battery 5 to form a front-back direction clamping and positioning mechanism. The first rear positioning cylinder 102 is slidably connected to the first upper support plate 1010. It is located on the side of the battery 5 away from the first front positioning reference block 103 and pushes the battery 5 against the first front positioning reference block 103 by moving, so as to achieve precise clamping in the front-back direction.

[0067] The first side clamping cylinder 104 is also slidably connected to the first positioning support frame 101 and is arranged on the adjacent side of the first front positioning reference block 103. Its main function is to clamp and position both sides of the battery 5. The two clamping blocks on the first side clamping cylinder 104 are respectively located on both sides of the battery 5. One of the clamping blocks is fixed, and the other clamping block can move according to the action of the first side clamping cylinder 104, so as to effectively clamp both sides of the battery 5. The transplanting cylinder 105 is arranged on the first lower support plate 1012 of the first positioning support frame 101 and is arranged vertically opposite to the first rear positioning cylinder 102. The main function of the transplanting cylinder 105 is to drive the entire first positioning support frame 101 to move along the X-axis direction of the equipment to ensure that the clamped battery 5 can be smoothly transferred to the next station. Through the coordinated work of the above components, the first battery positioning device 10 not only realizes the precise positioning and clamping of the battery 5, but also ensures the stability and accuracy of the battery 5 during the pre-bending process, significantly improving the overall work efficiency and reliability.

[0068] Refer to Figures 1 - 4 、 Figure 11, in one embodiment, the pre-bending assembly 1 further includes a bending line abutting device 11, and the bending line abutting device 11 includes a bending line abutting support plate 110, a first lifting cylinder 111, a first horizontal pushing cylinder 112, and a bending line abutting block 113;

[0069] The bending line abutting support plate 110 is disposed on a side of the first front positioning reference block 103 away from the battery 5. The first lifting cylinder 111 is disposed on the bending line abutting support plate 110.

[0070] The bending line abutting block 113 is adjustably connected to the first horizontal pushing cylinder 112 through a bending line abutting connection plate 114 on the first horizontal pushing cylinder 112. The first horizontal pushing cylinder 112 is configured to drive the bending line abutting block 113 to perform a first translation motion.

[0071] In the above embodiment, the pre-bending assembly 1 further includes a bending line abutting device 11, which is composed of a bending line abutting support plate 110, a first lifting cylinder 111, a first horizontal pushing cylinder 112, and a bending line abutting block 113. Among them, the bending line abutting support plate 110 is disposed on a side of the first front positioning reference block 103 away from the battery 5. As the basic support structure of the entire bending line abutting device 11, it is on the same side as the first front positioning reference block 103 and is behind the first front positioning reference block 103 relative to the battery 5, providing a stable installation platform for subsequent components. The first lifting cylinder 111 is fixedly connected to the bending line abutting support plate 110. Its main function is to drive the first horizontal pushing cylinder 112 to perform a lifting motion. In this way, the first horizontal pushing cylinder 112 can move in the vertical direction to adapt to different height requirements. The position design of the first lifting cylinder 111 enables it to flexibly adjust the height of the bending line abutting block 113 to ensure that it can accurately contact the circuit board 6 to be bent;

[0072] The first horizontal pushing cylinder 112 is connected to the top of the first lifting cylinder 111 and is used to drive the bending line block 113 to perform a translational motion.

The bending connection plate 114 is slidably connected to the first horizontal pushing cylinder 112 and is provided with a plurality of connection holes on the side close to the first front positioning reference block 103. These connection holes allow the bending line block 113 to be adjusted and fixed according to actual needs. The bending line block 113 is adjustably connected to the first horizontal pushing cylinder 112 through the bending connection plate 114. Its main function is to apply pressure to the circuit board 6 to be bent on the battery 5 at a predetermined position, so that the bending line block 113 reaches a predetermined position above the circuit board 6 to be bent. Therefore, a stable foundation is provided by the bending support plate 110. The first lifting cylinder 111 and the first horizontal pushing cylinder 112 jointly achieve the precise positioning of the bending line block 113 in the vertical and translational directions, while the bending line block 113 is responsible for performing the final bending operation, making the overall structure not only improve the accuracy and stability during the bending process, but also greatly simplify the operation process and reduce the need for manual intervention.

[0075] The bending push block 123 is adjustably connected to the second horizontal pushing cylinder 122 through a push block connection plate 124 on the second horizontal pushing cylinder 122. The second horizontal pushing cylinder 122 is used to drive the bending push block 123 to perform a second translational motion.

[0076] In the above embodiment, the pre-bending assembly 1 further includes a pushing and bending device 12, which is composed of a pushing support plate 120, a second lifting cylinder 121, a second horizontal pushing cylinder 122 and a bending push block 123.

Its moving direction is perpendicular to the moving direction of the lower bending cylinder 421, that is, the side positioning cylinder 426 moves in the front-back direction, so that the side positioning cylinder 426 can be independent of the action of the lower bending cylinder 421 and perform an additional X-axis direction adjustment on the circuit board to ensure its accurate positioning in the horizontal direction. The side positioning base block 427 is arranged on the side of the side positioning cylinder 426 close to the bending pressing block 422.
