Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a copper busbar shaping device. Background Technology

[0002] In the assembly process of new energy batteries, copper busbars are typically used to achieve electrical connections between cells and battery modules. To meet specific installation space requirements, copper busbars often need to undergo bending and shaping to conform to a predetermined structural form. However, the large copper busbars currently used are usually long and rigid, making them prone to positional shifts or unstable postures during bending and shaping. This can lead to inaccurate bending positions, or even localized warping or twisting of the copper busbar. This not only reduces bending accuracy but may also cause scratches or stress concentrations on the surface of the copper busbar, thereby affecting its conductivity and service life.

[0028] By adjusting the first clamping member 310 and the second clamping member 311 along the second horizontal direction, reliable clamping of copper busbars of different widths is achieved, improving the applicability and flexibility of the device.

[0029] In one embodiment, the second clamping assembly 32 includes a third clamping member 320 and a fourth clamping member 321, wherein: the third clamping member 320 is disposed on a support plate 20 on a first side of the clamping portion extending along a first horizontal direction, the third clamping member 320 extends along the first horizontal direction and is adjustable along the first horizontal direction, and a pressure-bearing surface extending along the first horizontal direction is provided on the side of the third clamping member 320 near the clamping portion; the fourth clamping member 321 is correspondingly disposed on a support plate 20 on a second side of the clamping portion extending along the first horizontal direction, the fourth clamping member 321 extends along the second horizontal direction and a pressure-applying surface extending along the first horizontal direction is provided at one end near the clamping portion, and the fourth clamping member 321 is adjustable along the first horizontal direction and the second horizontal direction respectively.

[0033] By cooperating with the pressure-bearing surface of the third clamping member 320 and the pressure-applying surface of the fourth clamping member 321, the copper busbar on the support plate 20 is effectively clamped and fixed in the clamping part. Furthermore, by setting the positions of the third clamping member 320 and the fourth clamping member 321 to be adjustable, the applicability and flexibility of the device are further improved.

[0034] In one embodiment, the clamping part is provided with at least one row of mounting holes on both sides extending along the first horizontal direction, and each row of mounting holes includes a plurality of mounting holes 11 spaced apart along the first horizontal direction on the support plate 20. The third clamping member 320 and the fourth clamping member 321 are detachably mounted above their respective mounting holes via bolt assembly 50.

[0035] Specifically, the mounting hole is set as the second threaded hole 11.

[0036] Specifically, a row of mounting holes is provided on one side of the clamping part where the third clamping member 320 is located, and two rows of mounting holes are provided at intervals along the second horizontal direction for the clamping part where the fourth clamping member 321 is located.

[0037] By setting mounting holes on the support plate 20 and using bolt assembly 50 to detachably install the third clamping member 320 and the fourth clamping member 321, the position of the clamping members can be flexibly adjusted. This provides a copper busbar shaping device that can be quickly adjusted according to different fixed positions to meet the fixing requirements of copper busbars of different lengths, thereby further improving the applicability of the device and the accuracy of bending and shaping.

[0038] In one embodiment, the bending assembly 40 includes a turntable 41, an operating lever 42, and a pressure block 43, wherein: the turntable 41 is rotatably mounted on the base 10 and located below the support plate 20 along its own center; the pressure block 43 is fixedly mounted on the turntable 41 with the pressure block 43 facing upward; the first clamping assembly 31 is provided with an arc-shaped first bending surface 430; the first end of the first clamping member 310 is provided with a second bending surface 3101; the first end of the second clamping member 311 is provided with a third bending surface 3111; the first bending surface 430 and the second bending surface 3101 and the second bending surface 3101 interfere with each other in the horizontal direction; the operating lever 42 is connected to the turntable 41 in a transmission manner; the operating lever 42 drives the pressure block 43 to rotate through the turntable 41 under the drive of external force to bend the copper busbar between the first bending surface 430 and the second bending surface 3101 or the third bending surface 3111.

[0039] The combination of turntable 41, operating lever 42 and pressure block 43, along with their cooperation with the first clamping assembly 31, facilitates the rapid and effective bending of the copper busbar extending from the first clamping assembly 31, thereby improving the efficiency and accuracy of bending and shaping.

[0040] In one embodiment, the bending assembly 40 further includes a limiting assembly 44, which is connected to the turntable 41 and the base 10 respectively, and is configured to limit the rotation angle of the turntable 41.

Turntable 41 stops rotating when first limiting block 441 contacts second limiting block 442 to limit the rotation angle of turntable 41.

[0045] Specifically, the scale is located in the clamping part.

[0046] By setting a scale on the support plate 20, the bending position can be directly measured, which further improves the accuracy of copper busbar shaping.

[0047] The working principle of the above-mentioned copper busbar shaping device is as follows: S1, the copper busbar is set on the support plate 20 and, according to the scale, one end of the copper busbar passes between the first clamping member 310 and the second clamping member 311 and extends out of the support plate 20 by a predetermined length. S2, Adjust the bolt assembly 50 so that the second clamping member 311 approaches the first clamping member 310 along the second horizontal direction until the copper busbar abuts against the first clamping member 310 and the second clamping member 311 on both sides along the width direction respectively. S3, Adjust the bolt assembly 50 so that the fourth clamping member 321 drives the pressure plate 3210 to approach the third clamping member 320 along the second horizontal direction until the copper busbar abuts against the bearing surface and the pressure application surface on both sides along the width direction, so that the copper busbar is fixed at the first end of the support plate 20. S4, the operating lever 42, driven by external force, drives the pressure block 43 to rotate toward the second bending surface 3101 or the third bending surface 3111 via the turntable 41, so as to bend and shape the copper busbar.
