Description

A battery flexible circuit board bending device Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a battery flexible circuit board bending device. Background Technology

[0002] A battery flexible circuit board, also known as a flexible printed circuit board, is a circuit structure attached to a battery to connect the battery to external electronic devices. During use, battery flexible circuit boards typically require bending to better adapt to and connect with external electronic devices.

[0003] In existing technologies, the flexible battery circuit board is typically bent in one step using a bending device after positioning the battery. However, this bending device and method are prone to the following problems:

[0004] 1. The bending equipment cannot accurately limit and clamp the unbent part of the battery flexible circuit board. During the bending process, the battery flexible circuit board is prone to displacement or deviation, which affects the bending effect of the battery flexible circuit board.

[0005] 2. Due to the nature of its material, the shape of a battery flexible circuit board that is not fully positioned cannot be clearly defined. It can be easily identified by bending equipment or other external instruments, thus making it susceptible to damage.

[0006] 3. After the bending equipment bends the battery flexible circuit board, due to the influence of the material of the battery flexible circuit board itself, the battery flexible circuit board will produce a certain elastic restoring deformation, which will result in the battery flexible circuit board not being bent in place. Summary of the Invention

[0007] To address the shortcomings of the existing technology, this utility model provides a battery flexible circuit board bending device. During the bending process, the flexible circuit board limiting mechanism can limit and clamp the battery flexible circuit board, effectively preventing displacement or deviation, thus improving the bending quality and stability. It also effectively prevents damage to the battery flexible circuit board due to collisions with equipment. Furthermore, the flexible circuit board bending mechanism can perform a second bend on the battery flexible circuit board after it has been limited by the limiting mechanism, overcoming the issue of incomplete bending due to elastic reset of the battery flexible circuit board.

[0008] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0009] This utility model provides a battery flexible circuit board bending device, comprising:

[0010] A battery positioning mechanism for placing and limiting the position of batteries;

[0011] A flexible circuit board limiting mechanism is arranged adjacent to the battery positioning mechanism to limit the non-bent portion of the battery flexible circuit board and to clamp the portion of the battery flexible circuit board near the bending line.

[0012] The flexible circuit board bending mechanism abuts against the flexible circuit board to be bent, causing the flexible circuit board to be bent once around the bending line, and then continues to cause the flexible circuit board after the first bend to be bent a second time around the bending line towards the flexible circuit board limiting mechanism.

[0013] As one preferred embodiment, the flexible board limiting mechanism includes a flexible board side clamping assembly disposed adjacent to the battery positioning mechanism for limiting the non-bent portion of the battery flexible board, and a flexible board end face clamping assembly disposed adjacent to the battery positioning mechanism for clamping the portion of the battery flexible board near the bending line.

[0014] As one preferred embodiment, the flexible circuit board side clamping assembly includes a first side clamping unit and a second side clamping unit that are disposed opposite to each other to limit the non-bent portion of the battery flexible circuit board.

[0015] As one preferred embodiment, the flexible circuit board end face clamping assembly includes a first end face clamping unit disposed adjacent to the battery positioning mechanism for supporting the lower end face of the portion of the flexible circuit board near the bend line, and a second end face clamping unit disposed adjacent to the first end face clamping unit for pressing the upper end face of the portion of the flexible circuit board near the bend line.

[0016] As one preferred embodiment, the first end face clamping unit includes a support limiting block that cooperates with the flexible board bending mechanism to achieve two bending of the battery flexible board, and a support driving module that drives the support limiting block to support the lower end face of the battery flexible board near the bending line.

[0017] As one preferred embodiment, the support limiting block includes a support limiting block body for supporting the lower end face of the portion adjacent to the bending line of the battery flexible circuit board, and an inclined structure disposed on the side of the support limiting block body adjacent to the flexible circuit board bending mechanism.

[0018] Furthermore, the end face of the supporting and limiting block body that supports the flexible battery board intersects with the end face of the inclined structure to form a side line; wherein, the side line is parallel to the bending line and is located in the same vertical plane.

[0019] As one preferred embodiment, the angle between the end face of the inclined structure and the end face of the supporting and limiting block body supporting the battery flexible plate is 15°-75°.

[0020] As one preferred embodiment, the flexible circuit board bending mechanism includes a bending member that abuts against the portion of the flexible circuit board to be bent, and a bending drive assembly that drives the bending member to rotate and move in order to bend the portion of the flexible circuit board to be bent.

[0021] As one preferred embodiment, the bending drive assembly includes a rotating bending unit disposed adjacent to the flexible plate limiting mechanism, and a movable bending unit connected to the bending member and disposed on the rotating bending unit.

[0022] As one preferred embodiment, the battery positioning mechanism includes a battery positioning component for initial battery positioning, and a battery clamping component movably disposed above the battery positioning component for complete battery positioning.

[0023] In summary, this utility model has at least the following advantages:

[0024] 1. The battery flexible circuit board bending device provided by this utility model can limit and clamp the battery flexible circuit board during the bending process. This not only effectively prevents the battery flexible circuit board from shifting or deviating, thus improving the bending quality and stability of the battery flexible circuit board, but also effectively prevents the battery flexible circuit board from being damaged due to collisions with the equipment.

[0025] 2. The battery flexible board bending device provided by this utility model can bend the battery flexible board twice after it has been limited by the flexible board limiting mechanism, so as to overcome the situation that the battery flexible board is not bent in place due to elastic reset.

[0035] 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.

[0036] 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.

[0037] Please refer to Figure 1. The battery flexible circuit board bending device of this embodiment includes a battery positioning mechanism 100, a flexible circuit board limiting mechanism 200 disposed adjacent to the battery positioning mechanism 100, and a flexible circuit board bending mechanism 300 abutting against the portion of the battery flexible circuit board to be bent. The battery positioning mechanism 100 is used for placing and limiting the battery; the flexible circuit board limiting mechanism 200 is used to limit the non-bending portion of the battery flexible circuit board and clamp the portion of the battery flexible circuit board adjacent to the bending line; the flexible circuit board bending mechanism 300 is used to drive the portion of the battery flexible circuit board to be bent once around the bending line, and then continue to drive the battery flexible circuit board after the first bend to bend a second time around the bending line towards the flexible circuit board limiting mechanism 200.

[0038] Please refer further to Figure 2. In some embodiments, the battery positioning mechanism 100 includes a battery positioning component 110 for initial battery positioning, and a battery clamping component 120 movably disposed above the battery positioning component 110 for complete battery positioning. The battery positioning component 110 primarily positions the battery horizontally, while the battery clamping component 120, together with the battery positioning component 110, positions the battery vertically. Further, the battery positioning component 110 includes a clamp positioning unit 111 for placing and positioning the battery, and a clamp adjusting unit 112 for adjusting the position of the clamp positioning unit 111. The battery clamping component 120 includes a battery clamping block 121 movably disposed above the clamp positioning unit 111 for clamping and positioning the battery within the clamp positioning unit 111, and a clamping drive unit 122 for driving the battery clamping block 121 to clamp the upper surface of the battery. Preferably, both the clamp adjustment unit 112 and the clamping drive unit 122 have unit groups that can realize the adjustment of component positions in the prior art; for example, motor adjustment unit group, cylinder adjustment unit group, etc., which are not the main inventive points of this technology, so they will not be described in detail here.

[0039] Please refer further to Figure 2. In some embodiments, the flexible circuit board limiting mechanism 200 includes a flexible circuit board side clamping assembly 210, which is disposed adjacent to the battery positioning mechanism 100 and used to limit the non-bent portion of the flexible circuit board, and a flexible circuit board end face clamping assembly 220, which is disposed adjacent to the battery positioning mechanism 100 and used to clamp the portion of the flexible circuit board near the bending line. The two components combined can effectively limit and clamp the non-bent portion and the portion near the bending line of the flexible circuit board, which can not only prevent the flexible circuit board from shifting or deviating during the bending process, thereby improving the bending quality and stability of the flexible circuit board; but also effectively prevent the flexible circuit board from being damaged due to collisions with the equipment after being limited.

[0040] Preferably, the flexible circuit board side clamping assembly 210 includes a first side clamping unit 211 and a second side clamping unit 212 disposed opposite to each other to limit the non-bending portion of the battery flexible circuit board; the first side clamping unit 211 and the second side clamping unit 212 combine to effectively clamp and limit both sides of the non-bending portion of the battery flexible circuit board, preventing horizontal stretching and vertical swinging of the non-bending portion of the battery flexible circuit board. Compared with the end face clamping limiting assembly, the side clamping limiting assembly not only achieves clamping and limiting of the battery flexible circuit board in the vertical direction, but also adjusts the stretching or movement of the battery flexible circuit board in the horizontal direction, thereby effectively improving the accuracy of battery flexible circuit board clamping and limiting.

[0041] Please refer further to Figure 2. In some embodiments, the flexible circuit board end face clamping assembly 220 includes a first end face clamping unit 221 disposed adjacent to the battery positioning mechanism 100 for supporting the lower end face of the portion of the flexible circuit board near the bend line, and a second end face clamping unit 222 disposed adjacent to the first end face clamping unit 221 for pressing the upper end face of the portion of the flexible circuit board near the bend line. The first end face clamping unit 221 and the second end face clamping unit 222, when combined, can effectively clamp and limit the portion of the flexible circuit board near the bend line to prevent this portion of the flexible circuit board from moving or deviating during the bending process.

[0042] Please refer further to Figure 4. The first end face clamping unit 221 includes a support limiting block 2211 that cooperates with the flexible board bending mechanism 300 to achieve two bends of the battery flexible board, and a support driving module 2212 that drives the support limiting block 2211 to support the lower end face of the battery flexible board near the bending line. Preferably, the support limiting block 2211 includes a support limiting block body 2211a for supporting the lower end face of the battery flexible board near the bending line, and an inclined structure 2211b disposed on one side of the support limiting block body 2211a near the flexible board bending mechanism 300, as shown in Figure 5; and the end face of the support limiting block body 2211a supporting the battery flexible board intersects with the end face of the inclined structure 2211b to form a side line; wherein, the side line is parallel to the bending line and located in the same vertical plane. When the flexible circuit board bending mechanism 300 comes into contact with the part of the flexible circuit board to be bent and drives it to bend, the side line that is parallel to the bending line and located in the same vertical plane can ensure that the part to be bent is bent around the bending line, so as to ensure the quality of the bending of the flexible circuit board.

[0043] The design of the inclined surface structure 2211b allows a triangular space to be formed on the side of the support limiting block body 2211a adjacent to the flexible plate bending mechanism 300. When the flexible plate bending mechanism 300 abuts against the portion of the battery flexible plate after one bend, causing it to continue moving towards the support limiting block body 2211a, the battery flexible plate after one bend can continue to bend around the side line of the support limiting block body 2211a, resulting in a final bending angle of the battery flexible plate that is greater than the required bending angle. This overcomes the situation where the battery flexible plate is not bent in place due to elastic reset. Preferably, the angle between the end face of the inclined surface structure 2211b and the end face of the support limiting block body 2211a supporting the battery flexible plate is 15°-75°; the design and selection can be adapted according to the elastic coefficient of the battery flexible plate.

[0044] Please refer further to Figure 4. The second end-face clamping unit 222 includes a flexible board clamping block 2221 movably disposed above the support limiting block 2211 to achieve upper vertical positioning of the portion of the flexible battery board near the bending line, and a flexible board clamping drive module 2222 for driving the flexible board clamping block 2221 to clamp the upper end face of the portion of the flexible battery board near the bending line. Preferably, both the support drive module 2212 and the flexible board clamping drive module 2222 have drive module groups that can realize component position adjustment in the prior art, such as cylinder drive module groups, motor drive module groups, etc., which are not the main inventive points of this technology, and therefore will not be described in detail here.

[0045] Please refer further to Figure 3. In some embodiments, the flexible circuit board bending mechanism 300 includes a bending member that abuts against the portion of the flexible circuit board to be bent, and a bending drive assembly 320 that drives the bending member to rotate and move to achieve bending of the portion of the flexible circuit board to be bent. Further, the bending drive assembly 320 includes a rotating bending unit 321, adjacent to the flexible circuit board limiting mechanism 200, for achieving a single rotational bending of the portion of the flexible circuit board to be bent, and a movable bending unit 322 connected to the bending member and disposed on the rotating bending unit 321. Preferably, the rotating bending unit 321 includes a rotating drive module 3211 adjacent to the flexible circuit board limiting mechanism 200, and a rotating linkage mounting bracket 3212 disposed at the drive end of the rotating drive module 3211 for mounting the movable bending unit.

[0046] During the bending process, the rotating bending unit 321 is activated once, driving the movable bending unit 322 and the bending component mounted on the rotating bending unit 321 to rotate until the bending component abuts against the part of the battery flexible circuit board to be bent. Subsequently, the rotating bending unit 321 continues to rotate, driving the movable bending unit 322 and the bending component to rotate, causing the battery flexible circuit board abutting against the bending component to bend around the side line of the support limiting block body 2211a. Then, the movable bending unit 322 is activated, driving the bending component to continue moving towards the support limiting block body 2211a, so that the battery flexible circuit board after the first bend continues to bend around the side line of the support limiting block body 2211a for a second time, forming a bending angle greater than the required bending angle, in order to overcome the situation where the battery flexible circuit board is not bent in place due to elastic reset.

[0047] As can be seen from the technical solutions of the above embodiments, the present invention provides a battery flexible circuit board bending device, which can not only effectively protect the battery flexible circuit board and improve the quality and stability of the battery flexible circuit board bending, but also effectively overcome the situation where the battery flexible circuit board is not bent in place due to elastic reset.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0050] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0051] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
