Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a battery protection board tab bending mechanism. Background Technology

[0002] The tabs on the protection board are conductive metal components that connect the lithium battery protection board to the battery cell. They are typically made of nickel, copper, or other metals with good conductivity. One end of the tab is soldered to the positive and negative terminals of the battery cell, and the other end is soldered to the circuit of the protection board, serving to transmit current.

[0003] After the battery cell and the protection board are spot-welded together, the tabs of the protection board generally need to be bent according to the process flow chart so that the protection board tabs as a whole meet the space requirements of battery assembly and typical internal structure.

[0004] In the existing technology, due to the product structure limitations of the battery protection board tabs, the bending requirements of the tabs are generally met manually using auxiliary fixtures. This not only results in low product bending efficiency and high labor costs, but also makes it difficult to guarantee the tolerance and quality requirements of manually bent products, making it difficult to achieve standardized production of battery products.

[0033] 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.

[0034] 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.

[0035] Please see the appendix Figure 1 and 2The battery protection board tab bending mechanism of this utility model includes a first product clamping component 100 corresponding to the battery protection board, a second product clamping component 200 corresponding to the first product clamping component 100, and a tab bending component 300 respectively connected to the first product clamping component 100 and the second product clamping component 200. The first product clamping component 100 is used to initially limit and install the protection board to be bent, and the second product clamping component 200 is used to fully limit and install the protection board to be bent. Further, the tab bending component 300 includes a swing bending unit (320), which is connected to the first product clamping component 100 and the second product clamping component 200 respectively, and is used to drive the fully limited battery protection board to rotate in the opposite direction to the swing direction, thereby bending the protection board tab.

[0036] The battery protection board tab bending mechanism of this embodiment utilizes a tab bending assembly 300 and a first product clamping assembly 100 and a second product clamping assembly 200 disposed on the tab bending assembly 300 to achieve automatic positioning and bending of the protection board tab to be bent. Compared with the method of manual bending using auxiliary jigs, it can not only replace manual bending operations, reduce labor input costs and manual operation difficulty, and effectively improve the bending efficiency of the protection board tab, thereby improving the efficiency of battery production, but also effectively meet the quality and tolerance requirements of the protection board tab bending, which is conducive to the realization of standardized battery production.

[0037] Please see the appendix Figure 2 In some embodiments, the tab bending assembly 300 includes an assembly linkage plate 310, a swing bending unit 320 connected to the first product clamping assembly 100 and the second product clamping assembly 200 respectively and mounted on the assembly linkage plate 310, and a bending drive unit 330 connected to the swing bending unit 320 and mounted on the assembly linkage plate 310. The assembly linkage plate 310 is used for the installation and connection of the assembly as a whole with the external structure, facilitating the linkage of the assembly's overall movement through the movement of the external structure; the swing bending unit 320 is used to bend the protective plate tab, and the bending drive unit 330 is used to provide the power source for bending the protective plate tab. Preferably, the bending drive unit 330 is a motor drive unit.

[0038] Furthermore, the swing bending unit 320 includes a pivot mounting module 321 disposed on both sides of the component linkage plate 310, and a tab bending pivot 322 respectively connected to the first product clamping component 100 and the second product clamping component 200 and rotatably disposed between the pivot mounting module 321. Preferably, the pivot mounting module 321 is a bearing mounting module connected to the tab bending pivot 322; please refer to the appendix for further details. Figure 3The tab bending shaft 322 has a U-shaped shaft structure, including a shaft connecting part 3221 connected to the bending drive unit 330 and rotatably mounted on the shaft mounting module 321, and a U-shaped rotating part 3222 disposed between the shaft connecting parts 3221 for mounting the first product clamping assembly 100 and the second product clamping assembly 200. When the shaft connecting part 3221 of the tab bending shaft 322 rotates under the driving action of the bending drive unit 330, the U-shaped rotating part 3222 connected to it swings under its drive, thereby causing the first product clamping assembly 100 and the second product clamping assembly 200 connected to the U-shaped rotating part 3222 to swing, so as to achieve bending of the protective plate tab.

[0039] Please refer to the appendix for further details. Figure 1-3 In some embodiments, the first product clamping assembly 100 includes a first clamping drive module 110 disposed on the tab bending shaft 322 of the tab bending assembly 300 for providing product clamping power; a first protective plate clamping block 120 disposed on the first clamping drive module 110 for limiting one side of the protective plate; and a second protective plate clamping block 130 corresponding to the first protective plate clamping block 120 and disposed on the movable end of the first clamping drive module 110. The second protective plate clamping block 130 can clamp and limit the other opposite side of the protective plate under the driving action of the first clamping drive module 110, thereby limiting the position of the protective plate in the horizontal direction.

[0040] Please refer to the appendix for further details. Figure 4 The first protective plate clamping block 120 includes a first protective plate clamping block body 121 and a first elastic protective pad 122 disposed on the first protective plate clamping block body 121; the second protective plate clamping block 130 includes a second protective plate clamping block body 131, a protective plate limiting part 132 disposed on the second protective plate clamping block body 131 for limiting and installing the protective plate, and a second elastic protective pad 133 disposed on the protective plate limiting part 132. The design of the first elastic protective pad 122 and the second elastic protective pad 133 can buffer the instantaneous stress applied to the protective plate by the protective plate clamping block, which can not only effectively ensure the stability of the protective plate positioning, but also effectively prevent the protective plate from deforming and ensure the quality of the protective plate tab bending.

[0041] Please see the appendix Figure 1-3In some embodiments, the second product clamping assembly 200 includes a clamping assembly mounting bracket 210 disposed on the tab bending shaft 322 of the tab bending assembly 300, a second clamping drive module 220 disposed on the clamping assembly mounting bracket 210, and a protective plate clamping block assembly 230 connected to the second clamping drive module 220 and slidably disposed on the clamping assembly mounting bracket 210. The protective plate clamping block assembly 230 is correspondingly disposed with the first protective plate clamping block 120 and the second protective plate clamping block 130, and is used to limit the position of the protective plate in the vertical direction under the driving action of the second clamping drive module 220, thereby achieving complete positioning of the protective plate.

[0042] Please refer to the appendix for further details. Figure 5 The protective plate clamping block assembly 230 includes a sliding block 231 connected to the movable end of the second clamping drive module 220 and slidably mounted on the clamping component mounting frame 210; a Z-shaped clamping block 232 corresponding to the first protective plate clamping block 120 and the second protective plate clamping block 130 in the first product clamping component 100 and disposed on the sliding block 231; a clamping limit block 233 disposed on the clamping component mounting frame 210; and an elastic reset member 234 connected at one end to the Z-shaped clamping block 232 and at the other end to the clamping limit block 233; preferably, the elastic reset member 234 is a spring reset member. When the second clamping drive module 220 is started, it can drive the sliding block 231 connected to it to move towards the adjacent first protective plate clamping block 120 and second protective plate clamping block 130, so that the Z-shaped pressing block 232 set on the sliding block 231 moves towards the protective plate and clamps and limits the protective plate; after the bending action is completed, the Z-shaped pressing block 232 can move away from the protective plate under the driving action of the second clamping drive module 220, so as to facilitate the processing of the next product to be bent; or, the second clamping drive module 220 can be turned off, so that the Z-shaped pressing block 232 is reset away from the protective plate under the pulling force of the elastic reset member 234.

[0043] Preferably, the Z-shaped clamping block 232 has a ramp structure corresponding to the protective plate. The ramp structure can not only effectively reduce the contact area between the side of the Z-shaped clamping block 232 and the protective plate, thereby reducing the possibility of the Z-shaped clamping block 232 impacting the protective plate within the positioning error range, but also effectively reduce the resistance during the movement of the Z-shaped clamping block 232, facilitating the smooth clamping and limiting of the protective plate.

[0044] Please see the appendix Figure 1 and 2In some embodiments, the battery protection board tab bending mechanism further includes a mechanism adjustment component 400 connected to the tab bending assembly 300 for adjusting the overall position of the mechanism. The entire battery protection board tab bending mechanism can be moved towards or away from the product to be processed by the mechanism adjustment component 400 to facilitate bending of the product. Further, the mechanism adjustment component 400 is a three-axis adjustment component, including an X-axis adjustment unit 410 connected to the component linkage plate 310 in the tab bending assembly 300 for adjusting the entire mechanism in the first horizontal direction, a Y-axis adjustment unit 420 connected to the X-axis adjustment unit 410 for adjusting the entire mechanism in the second horizontal direction, and a Z-axis adjustment unit 430 connected to the X-axis adjustment unit 410 or the Y-axis adjustment unit 420 for adjusting the entire mechanism in the vertical direction.

[0045] Preferably, the first clamping drive module 110 and the second clamping drive module 220 are both cylinder drive modules; the X-axis adjustment unit 410, the Y-axis adjustment unit 420 and the Z-axis adjustment unit 430 are all cylinder adjustment units.

[0046] As can be seen from the technical solutions of the above embodiments, the present invention provides a battery protection plate tab bending mechanism, which can not only replace manual bending operations, reduce labor input costs and manual operation difficulty, effectively improve the bending efficiency of the protection plate tab, thereby improving the efficiency of battery production, but also effectively meet the quality requirements and tolerance requirements of the protection plate tab bending, which is conducive to the realization of standardized battery production.
