Description

Technical Field

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

[0002] Battery flexible circuit board bending is one of the processes in battery production. It mainly involves bending the straight battery flexible circuit board into a bent structure at a certain angle.

[0003] In existing technologies, flexible battery boards are typically bent using either stamping equipment or manual bending with auxiliary tools. However, both of these bending methods often have the following drawbacks:

[0004] 1. During the stamping and bending process of flexible battery circuit boards, the stamping forming equipment applies significant impact force to the boards, which can easily lead to internal circuit breakage or detachment of electronic components, thus affecting the overall quality and stability of the battery circuit board. Furthermore, the flexible battery circuit board is typically connected to the battery cell before bending; therefore, the impact force from stamping and bending also affects the battery cell, further impacting the overall quality of the battery. Due to these factors, this processing method has been largely phased out.

[0005] 2. The manual bending and forming of flexible battery circuit boards using auxiliary tools can effectively avoid the impact of forming impact on the flexible battery circuit boards, but it still has the following problems: 1) The manual operation is difficult and the labor cost is high; 2) The bending and forming efficiency is low, and the quality of the bending and forming of the flexible battery circuit boards cannot be well controlled, which is not conducive to the standardized production of flexible battery circuit boards and batteries.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0008] This utility model provides a battery flexible circuit board rotation and bending device, comprising:

[0009] The bending and forming mechanism abuts against one side of the non-bent portion of the flexible battery board near the bend line, for limiting and bending the flexible battery board.

[0010] A bending and pressing mechanism is located opposite to the bending and forming mechanism and abuts against the other side of the non-bent portion of the battery flexible plate near the bend line, for further limiting the battery flexible plate.

[0011] And a rotating bending mechanism, which abuts against the part of the battery flexible circuit board to be bent, so as to drive the part of the battery flexible circuit board to be bent to rotate and bend around the bending line in the direction of the bending forming mechanism.

[0012] As one preferred embodiment, the bending forming mechanism includes a bending forming member abutting against one side of the non-bent portion of the battery flexible circuit board near the bend line, and a bending forming drive assembly for driving the bending forming member to press against one side of the non-bent portion of the battery flexible circuit board near the bend line.

[0013] As one preferred embodiment, the bending forming part is a hook forming part, including a bending forming part body and a hook portion disposed on the bending forming part body for pressing against the battery flexible plate; and the side of the hook portion pressing against the battery flexible plate forms an angle with its upper end face that is smaller than a preset bending forming angle.

[0014] As one preferred embodiment, the hook portion presses against the side of the battery flexible plate and intersects with its upper end surface to form a bending forming line, and the bending forming line is parallel to the bending line.

[0015] As one preferred embodiment, the side of the hook portion that presses against the flexible battery plate is perpendicular to its lower end surface; wherein, the lower end surface is parallel to the horizontal direction.

[0016] As one preferred embodiment, the driving direction of the bending and forming drive assembly is at an angle of 30°-75° to the plane on which the side of the bent and formed part presses against the battery flexible plate.

[0017] As one preferred embodiment, the bending forming part further includes a component clearance groove disposed on the upper end surface of the hook portion for avoiding electronic components on the battery flexible circuit board.

[0018] As one preferred embodiment, the bending and pressing mechanism includes a bending and pressing member abutting against the other side of the non-bent portion of the battery flexible circuit board near the bend line, and a bending and pressing drive assembly that drives the bending and pressing member to press against the other side of the non-bent portion of the battery flexible circuit board near the bend line.

[0021] In summary, this utility model has at least the following advantages:

[0022] 1. The battery flexible circuit board rotating bending device provided by this utility model combines a bending forming mechanism, a bending pressing mechanism and a rotating bending mechanism to realize the bending forming of battery flexible circuit boards. It can not only effectively reduce the difficulty of workers' work and reduce labor costs, but also effectively improve the efficiency and quality of battery flexible circuit board bending, which is beneficial to the standardized production of battery flexible circuit boards and batteries.

[0023] 2. The battery flexible circuit board rotating bending device provided by this utility model has a bending forming component in the bending forming mechanism. This component can not only abut against the non-bent part of the battery flexible circuit board near the bending line to limit the position of the battery flexible circuit board, but also cooperate with the rotating bending mechanism to achieve bending and shaping of the battery flexible circuit board. Furthermore, the side of the bending forming component that abuts against the battery flexible circuit board forms an angle with its upper end face that is smaller than the preset bending forming angle. When the rotating bending mechanism drives the battery flexible circuit board to bend, the angle at which the battery flexible circuit board bends towards the bending forming mechanism can be greater than the required forming angle, thereby overcoming the problem of incomplete bending caused by the elastic reset of the battery flexible circuit board.

[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 see the appendix Figure 1 The battery flexible circuit board rotation and bending device of this utility model includes a battery positioning mechanism 100, a bending forming mechanism 200 abutting one side of the non-bent portion of the battery flexible circuit board near the bend line, a bending pressing mechanism 300 opposite to the bending forming mechanism 200 and abutting the other side of the non-bent portion of the battery flexible circuit board near the bend line, and a rotation bending mechanism 400 abutting the portion of the battery flexible circuit board to be bent. The battery positioning mechanism 100 is used for placing and positioning the battery; the bending forming mechanism 200 is used for positioning and bending the battery flexible circuit board; the bending pressing mechanism 300 is used for further positioning the battery flexible circuit board to prevent displacement or deviation during bending; and the rotation bending mechanism 400 is used to drive the portion of the battery flexible circuit board to be bent to rotate and bend around the bend line towards the bending forming mechanism 200, thereby achieving the bending and forming of the battery flexible circuit board.

[0038] The battery flexible circuit board rotation and bending device in this embodiment combines a battery positioning mechanism 100, a bending and forming mechanism 200, a bending and pressing mechanism 300, and a rotation and bending mechanism 400 to achieve the bending and forming of the battery flexible circuit board. This not only effectively reduces the difficulty of workers' work and reduces labor costs, but also effectively improves the efficiency and quality of battery flexible circuit board bending, which is beneficial to the standardized production of battery flexible circuit boards and batteries.

[0039] Please refer to the appendix for further details. Figure 2 In some embodiments, the battery positioning mechanism 100 includes a battery positioning clamp assembly 110 for limiting the battery position, and a clamp adjustment assembly 120 connected to the battery positioning clamp assembly 110 for adjusting the position of the battery positioning clamp assembly 110. Preferably, the battery positioning clamp assembly 110 is a clamp assembly capable of limiting the battery position in the prior art, and the clamp adjustment assembly 120 is an adjustment assembly composed of a cylinder, a slide rail slider group, and a cable chain. This mechanism is not the main inventive point of this technical solution, so the specific structure is not limited, as long as the corresponding function can be achieved.

[0040] Please refer to the appendix for further details. Figure 3 In some embodiments, the bending forming mechanism 200 includes a bending forming member 210 abutting against one side of the non-bent portion of the battery flexible circuit board near the bend line, and a bending forming drive assembly 220 for driving the bending forming member 210 to press against one side of the non-bent portion of the battery flexible circuit board near the bend line. Further, the bending forming drive assembly 220 includes a drive angle adjustment mounting bracket 221 disposed adjacent to the battery positioning mechanism 100 for adjusting the angle of the bending forming member 210 against the battery flexible circuit board, and a forming member drive unit 222 disposed on the drive angle adjustment mounting bracket 221 for connecting the bending forming member 210; preferably, the forming member drive unit 222 is a cylinder drive unit.

[0041] More preferably, the driving direction of the bending and forming drive assembly 220 is at an angle of 30°-75° to the plane on which the bending and forming part 210 presses against the battery flexible plate. When the bending and forming drive assembly 220 is turned on, it can drive the bending and forming part 210 to move obliquely downward to press against the battery flexible plate. Compared with structures where the driving direction is horizontal or vertical, this not only effectively reduces the probability of interference between the component and other components, but also effectively reduces the overall volume of the device and the layout space it occupies.

[0042] Please refer to the appendix for further details. Figure 4In some embodiments, the bending forming part 210 is a hook forming part, including a bending forming part body 211 and a hook portion 212 disposed on the bending forming part body 211 for pressing against the battery flexible circuit board; and the side of the hook portion 212 pressing against the battery flexible circuit board forms an angle with its upper end face that is smaller than a preset bending forming angle. When the part of the battery flexible circuit board to be bent rotates and bends around the bending line and toward the bending forming mechanism 200 under the driving action of the rotating bending mechanism 400, the design that the side of the hook portion 212 pressing against the battery flexible circuit board and its upper end face are smaller than the preset bending forming angle allows the battery flexible circuit board to continue bending toward the upper end face of the hook portion 212 after bending to the preset bending forming angle, so that the final bending angle of the battery flexible circuit board is greater than the preset bending forming angle, thereby overcoming the problem of incomplete bending caused by the elastic reset of the battery flexible circuit board. Furthermore, the side of the hook portion 212 that presses against the battery flexible plate intersects with its upper end face to form a bending forming line 2121, and the bending forming line 2121 is parallel to the bend line. When the hook portion 212 presses against the battery flexible plate, the bending forming line 2121, which is parallel to the bend line, is basically in contact with it, allowing the battery flexible plate to be bent around the bending forming line 2121, thereby effectively improving the quality and stability of the bending forming. Preferably, the side of the hook portion 212 that presses against the battery flexible plate is perpendicular to its lower end face, wherein the lower end face is parallel to the horizontal direction. When the hook portion 212 presses against the battery flexible plate, its lower end face can press against the battery or the battery flexible plate located above the battery that does not need to be bent, so as to further limit and clamp the battery or battery flexible plate to prevent the battery and battery flexible plate from shifting during the bending process.

[0043] Furthermore, the bending forming part 210 also includes a component avoidance groove 213 disposed on the upper end surface of the hook portion 212 for avoiding electronic components on the battery flexible circuit board; the design of the component avoidance groove 213 can effectively prevent electronic components on the battery flexible circuit board from colliding with the equipment and falling off.

Figure 5 In some embodiments, the bending and pressing mechanism 300 includes a bending and pressing member 310 abutting against the other side of the non-bent portion of the battery flexible board near the bend line, and a bending and pressing drive assembly 320 driving the bending and pressing member 310 to press against the other side of the non-bent portion of the battery flexible board near the bend line. Further, the bending and pressing drive assembly 320 includes a mechanism mounting bracket 321 disposed adjacent to the battery positioning mechanism 100, and a pressing drive unit 322 disposed on the mechanism mounting bracket 321 and connected at its drive end to the bending and pressing member 310; preferably, the pressing drive unit 322 is a cylinder drive unit.

[0045] Please refer to the appendix for further details. Figure 6In some embodiments, the rotary bending mechanism 400 includes a rotary bending block 410 that abuts against the portion of the battery flexible circuit board to be bent, and a rotary bending assembly 420 that drives the rotary bending block 410 to bend the portion of the battery flexible circuit board to be bent around the bending line toward the bending forming mechanism 200. Further, the rotary bending assembly 420 includes a rotary drive unit 421 connected to the rotary bending block 410 for driving the rotary bending block 410 to rotate, and a rotary bending adjustment unit 422 connected to the rotary drive unit 421 for adjusting its position; preferably, the rotary drive unit 421 is a motor drive unit, and the rotary bending adjustment unit 422 is an adjustment unit composed of a belt pulley assembly, a slide rail slider assembly, and a lead screw.

[0046] As can be seen from the technical solutions of the above embodiments, the present invention provides a battery flexible circuit board rotation and bending device, which can not only effectively reduce the difficulty of workers' work and reduce labor costs, but also effectively improve the efficiency and quality of battery flexible circuit board bending, which is beneficial to the standardized production of battery flexible circuit boards and batteries.
