[0041] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] 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 rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] refer to Figures 1 to 4 The battery FPC soft board bending mechanism provided in this embodiment includes a positioning and conveying module 1, a limiting module 2 and a bending module 3. The limiting module 2 and the bending module 3 are both located at the conveying end position of the positioning and conveying module 1. In this embodiment, as Figure 2 and Figure 3 As shown, the battery includes a battery body A and a battery head B, and an FPC board C is provided on one side of the battery head B. Before bending, the FPC board C is in a horizontal state, and the bending module 3 is used to bend the FPC board C downward by about 90°.

[0045] The limiting module 2 includes a first limiting unit 21 and a second limiting unit 22. The first limiting unit 21 is located in the conveying direction of the positioning and conveying module 1 and is used to limit the position of the battery head B. The second limiting unit 22 is located in the bending direction of the bending module 3 and is used to limit the bending action of the bending module 3. In some embodiments, the first limiting unit 21 and the second limiting unit 22 can be set to be fixed or movable. Setting them to be fixed can ensure the stability and accuracy of the limiting, and is also conducive to ensuring the consistency of the bending operation and improving production quality.

[0046] It is understood that the first limiting unit 21 is located in the conveying direction of the positioning and conveying module 1. When the battery is conveyed to the conveying end point by the positioning and conveying module 1, the battery head B abuts the first limiting unit 21. At this time, the second limiting unit 22 is located below the FPC soft board C. The bending module 3 then bends the FPC soft board C downward until it abuts the second limiting unit 22, completing the bending action. By limiting the battery head B by the first limiting unit 21, secondary positioning of the battery is achieved, allowing the bending module 3 to more accurately align the bending area of ​​the FPC soft board C to be bent and perform the bending operation, effectively improving the quality of the bending operation. By limiting the bending action of the bending module 3 by the second limiting unit 22, the consistency of the bending angle of each battery FPC soft board C can be controlled, thereby ensuring product quality.

[0047] In some embodiments, the limiting module 2 further includes a limiting base 23, and the first limiting unit 21 and the second limiting unit 22 are both formed on the limiting base 23. By arranging the first limiting unit 21 and the second limiting unit 22 on the limiting base 23, it is possible to ensure that no relative displacement occurs between the first limiting unit 21 and the second limiting unit 22, thereby maintaining the consistency of each limiting action, which is conducive to improving the accuracy and consistency of the bending operation and further improving production quality.

[0048] As a further optimization, the limiting module 2 further includes a fine-tuning drive unit 24, the driving end of which is connected to the limiting base 23. The second limiting unit 22 is located on the side of the battery head B. The fine-tuning drive unit 24 is used to drive the second limiting unit 22 to push against the battery head B. In this embodiment, the fine-tuning drive unit 24 is a fine-tuning cylinder.

[0049] It should be noted that the fine-tuning drive unit 24 directly drives the limiting base 23 to make subtle movements parallel to the battery head B. Since the second limiting unit 22 is formed on the limiting base 23, the second limiting unit 22 also makes subtle movements under the drive of the fine-tuning drive unit 24. At the same time, since the second limiting unit 22 is located to the side of the battery head B, it is driven by the fine-tuning drive unit 24 to push against the battery head B, causing slight displacement of the battery head B. The provision of the fine-tuning drive unit 24 enables subtle adjustments to the position of the battery head B, making the positioning of the battery head B and the FPC C located to the side of the battery head B more precise, further improving the accuracy of the bending operation and enhancing product quality.

[0050] The battery FPC soft board bending mechanism of this embodiment limits the battery head through the first limiting unit, which can achieve more accurate alignment and bending, thereby improving the quality of the bending operation; by limiting the bending action of the bending module through the second limiting unit, it can control the consistency of the bending angles of each battery FPC soft board, thereby improving product quality; by arranging the first limiting unit and the second limiting unit on the limiting base, it can further improve the accuracy and consistency of the bending operation and improve the production quality; by providing a fine-tuning drive unit, the positioning of the battery head and the FPC soft board can be made more precise, thereby further improving the accuracy of the bending operation.

[0051] Example 2

[0052] As a further optimization of Example 1, refer to Figures 5 to 8The positioning and conveying module 1 includes a horizontal drive unit 11 and a positioning unit 12 connected to the driving end of the horizontal drive unit 11. In this embodiment, the horizontal drive unit 11 is a horizontally movable module. The positioning unit 12 includes a positioning platform 121 and a first positioning assembly 122, a second positioning assembly 123, and a third positioning assembly 124 disposed around the positioning platform 121. The positioning platform 121 is provided with suction holes to secure the batteries positioned thereon.

[0053] In one embodiment, the first positioning assembly 122 and the second positioning assembly 123 are located on opposite sides of the positioning platform 121, and the second positioning assembly 123 and the third positioning assembly 124 are located on the same side of the positioning platform 121. During positioning, the first positioning assembly 122 moves toward the battery body A and abuts against the side of the battery body A to position the battery body A; the second positioning assembly 123 moves toward the side of the FPC board C and abuts against the side of the FPC board C to position the FPC board C horizontally; and the third positioning assembly 124 moves toward the lower surface of the FPC board C and abuts against the lower surface of the FPC board C to position the FPC board C vertically.

[0054] The second and third positioning assemblies 123, 124 position the FPC board C in different directions, respectively, to initially define the shape of the FPC board C. This prevents the FPC board C from opening too far, potentially affecting subsequent bending operations. Furthermore, it helps maintain the consistency of the shapes of each FPC board C, improving product quality. It should be noted that after completing their positioning, the first, second, and third positioning assemblies 122, 123, and 124 all retract and reset, preventing interference with subsequent bending operations and ensuring an orderly process.

[0055] The bending module 3 includes a rotational drive unit 31 and a bending unit 32 connected to the drive end of the rotational drive unit 31. In this embodiment, the rotational drive unit 31 is a rotary drive cylinder that drives the bending unit 32 to rotate vertically. The rotation angle of the bending unit 32 corresponds to the bending angle of the FPC board C. During the bending operation, the bending unit 32 abuts the upper surface of the FPC board C. The rotational drive unit 31 then drives the bending unit 32 to rotate downward. The bending unit 32 pushes the FPC board C downward and abuts the second stopper 22, completing the bending operation.

[0056] In some embodiments, a buffer component, such as a buffer spring or a buffer silicone pad, may be provided on the bending unit 32 to prevent the bending unit 32 from excessively squeezing the FPC soft board C during the bending process and causing damage to the FPC soft board C.

[0057] In some embodiments, the battery FPC bending mechanism further includes a fixing module 4, located above the conveying endpoint of the positioning and conveying module 1. Fixing module 4 includes a first fixing unit 41 and a second fixing unit 42. The first fixing unit 41 is used to press and secure the battery body A during the bending process, while the second fixing unit 42 is used to press and secure the battery head B during the bending process. By securing the battery body A and the battery head B, respectively, the first fixing unit 41 and the second fixing unit 42 prevent the battery from shifting during the bending process, ensuring a high-quality bending operation.

[0058] In some embodiments, the first fixing unit 41 and the second fixing unit 42 can be connected to the driving end of the same driving cylinder, approach the battery under the drive of the same driving cylinder, and press against the battery body A and the battery head B respectively; in other embodiments, the first fixing unit 41 and the second fixing unit 42 can also be independently connected to the driving cylinder, and the downward pressing and abutting action is completed by the drive of the respectively connected driving cylinders.

[0059] The battery FPC soft board bending mechanism of this embodiment can achieve both the positioning of the battery body and the positioning and shaping of the FPC soft board through the cooperation of the first positioning component, the second positioning component and the third positioning component, thereby ensuring the orderliness of subsequent bending operations and at the same time guaranteeing the production operation quality and product quality; by setting a fixing module to further fix the battery body and the battery head, it can prevent the battery from being displaced during the bending operation, thereby improving the operation quality.

[0062] As one embodiment, the loading and unloading mechanism 100 includes a loading module 101, a unloading module 102, and a horizontal drive module 103. The horizontal drive module 103 is provided with a first drive end 104 and a second drive end 105. The loading module 101 is connected to the first drive end 104, and the unloading module 102 is connected to the second drive end 105. In some embodiments, the horizontal drive module 103 can be a dual-actuator linear motor module, wherein the dual-actuator corresponds to the first drive end 104 and the second drive end 105. Driven by the horizontal drive module 103, the loading module 101 and the unloading module 102 can move back and forth along the same straight line to perform battery loading and unloading operations, respectively.

[0063] In some embodiments, there may be multiple battery FPC flexible board bending mechanisms 200, and the multiple battery FPC flexible board bending mechanisms 200 are arranged in sequence along the driving direction of the horizontal driving module 103, thereby enabling simultaneous operation of multiple bending stations and effectively improving battery production efficiency.

[0064] In some embodiments, the battery FPC flexible board bending equipment also includes a blanking and flipping mechanism 300 located on the operating path of the blanking module 102. The blanking and flipping mechanism 300 includes an adsorption module 301, a first driving module 302 for driving the adsorption module 301 to rotate, and a second driving module 303 for driving the adsorption module 301 and the first driving module 302 to move up and down. In this embodiment, the first driving module 302 is a rotary driving cylinder, and the second driving module 303 is a vertical driving cylinder.

[0065] When the unloading module 102 unloads a battery onto the adsorption module 301, it secures the battery and, driven by the first drive module 302, flips 180°. Driven by the second drive module 303, it then moves downward, unloading the battery to the next workstation. The unloading flipping mechanism 300 enables pre-unloading flipping of the battery, ensuring that the unloaded battery meets the requirements of the next production station, improving the applicability of the battery FPC bending equipment.
