[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] New energy electric vehicles typically include complex circuit systems, in which copper busbars connect key components such as batteries, motors, and controllers. The specialized structural designs of batteries and motors limit interior space, leading to the widespread use of special-shaped copper busbars in vehicle interior design.

[0004] The structure of special-shaped copper busbars is generally complex. Therefore, it is difficult to meet the inspection standards of special-shaped copper busbars by using tools such as calipers and micrometers for two-dimensional inspection. However, the existing three-dimensional inspection method for the size inspection of special-shaped copper busbars is too expensive, the structure is complicated to replace, and it is difficult to use. Special training for operators is required.

The following implementation methods will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0026] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, as appropriate.

[0027] See Figure 1 , is a tooling structure for inspecting a special-shaped copper busbar of this embodiment, used for inspecting a copper busbar 100, wherein the copper busbar 100 includes an arcuate portion 101 and a terminal 102, wherein the terminal 102 has a connecting end 1021 and a welding end 1022 connected to each other, and the connecting end 1021 of the terminal 102 has a through hole, and the position between the connecting end 1021 and the welding end 1022 of the terminal 102 is connected to the arcuate portion 101; wherein the tooling structure for inspecting a special-shaped copper busbar includes:

[0028] The base 1 includes a limit pin 11, the size of which matches the size of the through hole;

[0029] The lower limit mechanism 2 is arranged on the base 1 and includes a lower limit seat 21 and a limit rod 22. The limit rod 22 is detachably mounted on the end of the lower limit seat 21, and one end of the limit rod 22 is arranged toward the base 1.

[0030] The upper limit mechanism 3 is arranged on the base 1 and includes an upper limit mold 31 and a driving unit 32. One side of the upper limit mold 31 is connected to the driving unit 31 so that the driving unit 32 can drive the upper limit mold 31 to move back and forth along the first direction by moving up and down;

[0031] Among them, when the through hole of the connecting end of the terminal 102 is sleeved on the limit pin 11, the position of the arc portion 101 matches the movable direction of the upper limit mold 31, so that when the upper limit mold 31 moves to the preset position along the first direction shown, the arc portion 101 can fit with the upper limit mold 31.

[0032] Through the above structure, when in use, the operator only needs to install the terminal 102 of the copper busbar 100 with the side of the welding end 1022 facing the limit pin 11 on the base 1, so that the through hole of the welding end 1022 is sleeved on the limit pin 11, and then the limit rod 22 in the lower limit mechanism 2 can be started to press downward relative to the lower limit seat 21, so that the connecting end 1021 is pressed against the base 1 by the limit rod 22. At this time, the arc-shaped portion 101 is also positioned at the same time. Then, the operator drives the driving part 32 of the upper limit mechanism 31 to move downward, so that the driving part 32 drives the upper limit mold 31 to move synchronously along the first direction toward the arc portion 101, until the upper limit mold 31 and the arc portion 101 fit together to the greatest extent. At this time, the size of the copper busbar 100 itself can be tested - if the size of the terminal 102 of the copper busbar 100 does not meet the preset size requirements, the connecting end 1021 of the terminal 102 cannot be smoothly installed on the base 1; if the size of the arc portion 101 of the copper busbar 100 does not meet the preset size requirements, there is an incomplete fit between the arc portion 101 and the upper limit mold 31 of the upper limit mechanism 31.

[0033] During the above-mentioned use process, the operator only needs to install the terminal 102 of the copper busbar 100 on the base 1, and after positioning it through the lower limit mechanism 2, and then use the upper limit mold 31 of the upper limit mechanism 31 to align the arc portion 101 of the copper busbar 100, thereby quickly completing the entire detection process. The steps are simple and new operators can quickly get started without training. At the same time, when it is necessary to test a new model of copper busbar 100, it is only necessary to adjust the position and size of the limit pin 11 on the base 1 for limiting the copper busbar 100 and replace the mold of the upper limit mold 31, thereby expanding the scope of application of this embodiment and having a lower cost under the modular design.

[0034] Furthermore, the upper limit mechanism 3 shown also includes a guide post 33. The guide post 33 extends along the first direction. The upper limit mold 31 is provided with a guide hole. The inner diameter of the guide hole matches the outer diameter of the guide post 33. The upper limit mold 31 is slidably mounted on the guide post 33. At the same time, the guide posts 33 and the guide holes are combined in two groups. Specifically, a guide hole is provided on each side of the upper limit mold 31 perpendicular to the first direction. The upper limit mold 31 is guided and limited by the two guide posts 33 on both sides of the upper limit mold 31, making the movement of the upper limit mold 31 more stable and precise, thereby improving the durability and positioning accuracy of this embodiment.

[0035] Furthermore, the special-shaped copper busbar detection tooling structure also includes a thickness detection mechanism 4, which includes a thickness detection base 41 and a thickness detection rod 42. The thickness detection base 41 and the thickness detection rod 42 are connected by a rotating shaft so that the thickness detection rod 42 can rotate around the thickness detection base 41, wherein the thickness detection rod 42 can rotate to a position adjacent to the welding end 1022. Through the above structure, after the copper busbar 100 is positioned, the thickness detection rod 42 of the thickness detection mechanism 4 is rotated toward one side of the copper busbar 100 and dropped. During the falling process, if the size of the welding end 1022 meets the requirements, one side of the thickness detection rod 42 in the thickness detection mechanism 4 can just pass closely with the welding end 1022. If the size of the welding end 1022 meets the requirements, one side of the thickness detection rod 42 in the thickness detection mechanism 4 will be blocked by the welding end 1022 during the falling process, or there will be a significant distance between the welding end 1022 and the thickness detection rod 42.

[0036] Furthermore, the driving portion 32 includes a driving seat 321 and a threaded rod 322. The threaded rod 322 extends along a first direction. One end of the threaded rod 322 is rotatably disposed on the base 1. The threaded rod 322 and the driving seat 321 are threadedly connected. The driving seat 321 is connected to the upper limit mold 31, so that when the threaded rod 322 is driven to rotate, the driving seat 321 can drive the upper limit mold 31 to reciprocate along the first direction. In one embodiment, a rotating handle 323 for driving the threaded rod 322 to rotate is provided at the end of the threaded rod 322 away from the base 1. During testing, the operator only needs to shake the rotating handle 323 to cause the rotating handle 323 to drive the threaded rod 322 to rotate. Since the threaded rod 322 is limited along the first direction, the driving seat 321 is displaced in the first direction relative to the threaded rod 322. In another embodiment, a motor is provided at the end of the threaded rod 322 away from the base 1 to drive the threaded rod 322 to rotate. During testing, the operator only needs to send an electrical signal to the motor to rotate the threaded rod 322. Since the threaded rod 322 is limited in the first direction, the drive base 321 is displaced in the first direction relative to the threaded rod 322. The specific power source of the drive unit 32 can be set according to cost requirements.
