[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] refer to Figures 1 to 5 The battery protection board flexible board shaping device provided in this embodiment includes a battery positioning mechanism 1 and a flexible board shaping mechanism 2 disposed on one side of the battery positioning mechanism 1. The flexible board shaping mechanism 2 includes a flexible board fixing component 21, a first shaping component 22 and a second shaping component 23. The flexible board fixing component 21 is used to fix the tail of the flexible board, and the first shaping component 22 and the second shaping component 23 are used to shape the bent part of the flexible board.

[0042] The first shaping assembly 22 includes a first shaping member 221 and a first driving member 222. The first driving member 222 is used to drive the first shaping member 221 to press against the flexible board bending portion along the first direction X. The second shaping assembly 23 includes a second shaping member 231 and a second driving member 232. The second driving member 232 is used to drive the second shaping member 231 to press against the flexible board bending portion along the second direction Y. The first direction X and the second direction Y are perpendicular to each other.

[0043] It should be noted that the first forming component 221 and the second forming component 231 respectively press against different positions of the bent portion of the flexible sheet, such as... Figure 3 As shown, the protective board flexible board 100 includes a flexible board tail 101 and a flexible board bending portion 102. The flexible board bending portion 102 is arc-shaped and is divided into a first shaping portion 103 and a second shaping portion 104. The first shaping portion 103 is connected to the second shaping portion 104, and the first shaping portion 103 is located between the flexible board tail 101 and the second shaping portion 104.

[0044] During the shaping process, the flexible circuit board fixing assembly 21 abuts against the tail 101 of the flexible circuit board. The first shaping component 221 presses against the outer surface of the first part to be shaped 103 along the first direction X, and the second shaping component 231 presses against the outer surface of the second part to be shaped 104 along the second direction Y. The outer surface of the flexible circuit board bending portion 102 is completely wrapped and squeezed by the first shaping component 221 and the second shaping component 231, so that the flexible circuit board bending portion 102 forms a fixed shape under the action of external force. Through the cooperation of the first shaping component 221 and the second shaping component 231, the flexible circuit board bending portion 102 is shaped in all directions. At the same time, the abutment and fixation of the tail 101 of the flexible circuit board by the flexible circuit board fixing assembly 21 can also achieve the shaping of the tail 101 of the flexible circuit board to a certain extent, making the overall shape of the protective board flexible circuit board 100 more regular, thereby meeting the requirements of subsequent production and assembly, and the shape of each protective board flexible circuit board 100 is also more consistent, which is conducive to improving the quality of battery products.

[0045] In some embodiments, a first arc-shaped recess 2211 is formed on the end face of the first forming member 221 that contacts the flexible board bending portion, and a second arc-shaped recess 2311 is formed on the end face of the second forming member 231 that contacts the flexible board bending portion. When the first forming member 221 and the second forming member 231 are moved into position, the first arc-shaped recess 2211 connects with the second arc-shaped recess 2311 to form an arc-shaped groove, and the outer surface of the flexible board bending portion 102 fits tightly against the inner wall of the groove, thereby forming a more standardized shape. Since the shaping of the flexible board bending portion 102 by the first shaping component 221 and the second shaping component 231 does not actually change the basic shape of the flexible board bending portion 102 itself, but rather regularizes the basic shape of the flexible board bending portion 102, the first arc-shaped recess 2211 and the second arc-shaped recess 2311 can fit more closely to the basic shape of the flexible board bending portion 102, thereby achieving a better shaping effect.

[0046] The flexible circuit board fixing assembly 21 includes a flexible circuit board fixing member 211 and a third driving member 212. The third driving member 212 is used to drive the flexible circuit board fixing member 211 to abut against the tail of the flexible circuit board. The driving direction of the third driving member 212 is parallel to the first direction X. In some embodiments, a buffer spring can be provided between the driving ends of the flexible circuit board fixing member 211 and the third driving member 212 to reduce the impact force when the flexible circuit board fixing member 211 abuts against the tail of the flexible circuit board, avoid damage to the electrical connection components at the tail of the flexible circuit board, and protect the flexible circuit board.

[0047] In this embodiment, the first drive member 222, the second drive member 232 and the third drive member 212 can be a drive motor or a drive cylinder.

[0048] The battery protection board flexible circuit board shaping device of this embodiment achieves all-round shaping of the flexible circuit board bending portion by having the first and second shaping components press against it in different directions. This improves the regularity of the flexible circuit board shape, enabling it to meet subsequent production and assembly requirements. It also enhances the consistency of the shapes of each protective circuit board, thus improving battery production quality. By providing the first and second arc-shaped recesses, the device better conforms to the basic shape of the flexible circuit board bending portion, resulting in tighter contact between the first and second shaping components and the bending portion, further improving the shaping effect.

[0049] Example 2

[0050] As a further optimization of Example 1, refer to Figure 6The battery positioning mechanism 1 includes a positioning platform 11, a first positioning component 12 and a second positioning component 13 disposed on adjacent sides of the positioning platform 11. A reference block 14 is disposed on one side of the positioning platform 11. The first positioning component 12 is positioned opposite to the reference block 14. The flexible circuit board shaping mechanism 2 is disposed on one side of the positioning platform 11 and is positioned opposite to the second positioning component 13. The first positioning component 12 is used to push the battery body against the reference block 14, and the second positioning component 13 is used to push the battery body towards the flexible circuit board shaping mechanism 2, so that the battery body reaches the set position to achieve the purpose of battery positioning.

[0051] The first positioning assembly 12 includes a first positioning element 121 and a fourth driving element 122 for driving the first positioning element 121 to move toward the reference block 14. The second positioning assembly 13 includes a second positioning element 131 and a fifth driving element 132 for driving the second positioning element 131 to move a fixed distance toward the flexible board forming mechanism 2. When the battery is loaded onto the positioning platform 11, the first positioning element 121 first pushes the battery against the reference block 14 under the drive of the fourth driving element 122. Then, the second positioning element 131 moves a fixed distance under the drive of the fifth driving element 132, pushing the battery to the set position, thus completing the positioning of the battery. Through the cooperation of the first positioning assembly 12 and the second positioning assembly 13, the battery can be positioned from two different directions with high positioning accuracy.

[0052] In this embodiment, the fourth driving member 122 can be a drive motor or a drive cylinder, and the fifth driving member 132 is a high-precision driving member capable of driving the second positioning member 131 to move a specific distance, such as a servo motor or a linear motor.

[0055] In some embodiments, the conveying mechanism 4 includes a first drive assembly 41 and a first conveying assembly 42 and a second conveying assembly 43 connected to the drive end of the first drive assembly 41. The first drive assembly 41 is used to drive the first conveying assembly 42 and the second conveying assembly 43 to move horizontally. The first drive assembly 41 can be a horizontal drive module. The first conveying assembly 42 operates between the loading mechanism 3 and the battery positioning mechanism 1, and the second conveying assembly 43 operates between the battery positioning mechanism 1 and the unloading mechanism 5.

[0056] The first transport assembly 42 includes a first adsorption member 421 and a sixth driving member 422 for driving the first adsorption member 421 to move vertically. The second transport assembly 43 includes a second adsorption member 431 and a seventh driving member 432 for driving the second adsorption member 431 to move vertically. Both the first adsorption member 421 and the second adsorption member 431 are used to adsorb and fix the battery body. In some embodiments, a buffer spring can be provided between the driving ends of the first adsorption member 421 and the sixth driving member 422, and a buffer spring can also be provided between the driving ends of the second adsorption member 431 and the seventh driving member 432. This can prevent excessive pressure from the first adsorption member 421 and the second adsorption member 431 on the battery during downward adsorption, thus preventing damage to the battery and further ensuring the production quality of the battery.

[0057] In some embodiments, the feeding mechanism 3 includes a horizontal conveying assembly 31 and a feeding positioning assembly 32. The feeding positioning assembly 32 is located at the end point of the horizontal conveying assembly 31. The horizontal conveying assembly 31 may include a conveyor belt and a belt drive motor for driving the conveyor belt.
