Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. Before leaving the factory, lithium-ion batteries often need to undergo electrical testing.
[0003] The new energy vehicle market is currently vast, and the technological development of new energy batteries is booming. Battery modules, composed of multiple battery cells, offer significant advantages in performance and energy efficiency. Therefore, employing automated equipment to assist in battery module assembly has become a necessary technology to improve assembly efficiency, greatly enhancing battery production and assembly efficiency.

Thus, battery electrical testing equipment is needed during battery production and processing, and further research is required to develop a suitable battery electrical testing device.
[0004] However, in actual use, it still has some drawbacks, such as:
[0005] 1. The battery cannot be properly secured, making it prone to displacement during testing and resulting in inaccurate results.
[0006] 2. During testing, the contact area between the testing equipment and the battery testing end is not uniform, resulting in unstable testing, inconsistent measurement results, and easy misjudgment of the product. Utility Model Content
[0007] Therefore, it is necessary to address the problems of existing battery electrical testing devices failing to properly fix the battery during battery electrical performance testing, which makes lithium batteries prone to displacement during testing, leading to inaccurate testing, inconsistent contact areas between the testing equipment and the battery testing end, unstable testing, inconsistent measurement results, and easy misjudgment of products. A new battery electrical testing mechanism should be provided, which has a simple structure, fast and accurate testing, stability and high efficiency, and ensures product quality.
[0008] The technical solution adopted to solve the above problems is: a battery electrical testing mechanism, including: a bracket, a positioning component disposed on the bracket and moving in a first direction for fixing the battery, and a testing component disposed on the bracket and moving in a second direction for testing the battery. The positioning component is provided with a number of slots, and the testing component is provided with a number of testing units consistent with the number of slots. The testing unit is provided with a testing clip for clamping the battery testing end and making large-area contact with the battery testing end.

[0010] In a preferred embodiment, it further includes a limiting component with a portion disposed on the support in the direction of movement of the test component and another portion disposed on the test component. The limiting component includes a stop fixed on the support and a travel limiter disposed on the test component.
[0011] In a preferred embodiment, the test component further includes a first sliding module disposed on the bracket, a mounting frame disposed on the first sliding module, a vertical driver disposed on the bracket to drive the first sliding module to move the mounting frame back and forth in a second direction, a detection unit disposed on the mounting frame, and a resistance detector disposed on the mounting frame and connected to the detection clip by a wire.

[0013] In a preferred embodiment, the clip connecting block is made of acetal or insulating material.
[0014] In a preferred embodiment, the end face of the detection clip at the battery detection end is configured as a wavy end face.
[0015] In a preferred embodiment, the positioning component further includes a second sliding module disposed on the bracket. The second sliding module is provided with a horizontal connecting plate. The bracket is provided with a horizontal driver that drives the horizontal connecting plate to reciprocate along a first direction.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0021] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a battery electrical testing mechanism, which is used on automated battery assembly production equipment. The battery electrical testing mechanism includes a support 10, on which a positioning component 20 that moves in a first direction and a testing component 30 that moves in a second direction are provided.
[0022] The positioning component 20 is mainly used to fix the battery. The positioning component 20 includes a second sliding module 21 on the bracket 10. A horizontal connecting plate 22 is provided on the second sliding module 21. A horizontal driver 23 is provided on the bracket 10 to drive the horizontal connecting plate 22 to reciprocate along a first direction. A clamping plate 24 is provided on the horizontal connecting plate 22 at one end away from the horizontal driver 23. Several clamping positions 25 are equally spaced on the clamping plate 24. The clamping positions 25 match the battery. The horizontal driver 23 drives the horizontal connecting plate 22 to move the clamping plate 24 along the first direction, so that the clamping plate 24 clamps the battery delivered by the battery assembly automated production equipment into the clamping positions 25 to position the battery and prevent the battery from moving when the test component 30 is detected, thereby improving the accuracy of the test.
[0023] The testing component 30 is mainly used to test the battery. The testing component 30 includes a first sliding module 31 mounted on the bracket 10. A mounting frame 32 is mounted on the first sliding module 31. A vertical driver 33 is mounted on the bracket 10 to drive the first sliding module 31 to move the mounting frame 32 back and forth in a second direction. A detection unit 34 is mounted on the mounting frame 32 in a number and position corresponding to the number of slots 25. A resistance detector 35 is mounted on the mounting frame 32 and connected to the detection clip 342 by a wire. The vertical driver 33 drives the mounting frame 32 to move in the second direction, so that the detection unit 34 gradually approaches the battery clamped by the slot 25. The detection unit 34 tests the battery and feeds the information back to the resistance detector 35 to determine whether the battery's charging and discharging performance is normal.
[0024] In addition, to ensure the stability of the test, the test unit 34 includes a clamp cylinder 340 mounted on the mounting bracket 32. Each clamp of the clamp cylinder 340 is provided with a clamping plate connecting block 341. A detection clamping plate 342 is installed on the two clamping plate connecting blocks 341. The contact area between the detection clamping plate 342 and the battery test end is increased, and the end face of the detection clamping plate 342 at the battery test end is set as a wavy end face. By increasing the contact area of the detection clamping plate 342 and setting the contact surface as a wavy shape, the detection end of the battery can be effectively protected, and the stability of the test is improved.
[0025] As can be seen from the above, in this embodiment, the first direction and the second direction are set perpendicularly, which enables the vertical actuator 33 to drive the detection unit 34 to intersect with the battery on the slot 25, thereby realizing the detection of the battery. In addition, in this embodiment, the first sliding module 31 and the second sliding module 21 are composed of two slide rails and several sliders; the horizontal actuator 23 and the vertical actuator 33 are cylinders.
[0026] Preferably, the clamping connecting block 341 can be made of acetal steel, which can ensure the hardness, wear resistance and high temperature resistance of the clamping connecting block 341 and prevent deformation of the clamping connecting block 341; in other embodiments, the clamping connecting block 341 can be made of insulating material.
[0027] The battery electrical testing mechanism provided in this embodiment also includes a limiting component 40 with a portion disposed on the bracket 10 in the direction of movement of the testing component 30 and another portion disposed on the testing component 30. The limiting component 40 includes a stop block 41 fixed on the bracket 10 and a travel limiter 42 disposed on the testing component 30. By setting the limiting component 40, the height of the testing component 30 can be adjusted, and it also serves as a limiting component.
[0028] In summary, this utility model uses the positioning component 20 to drive the locking position 25 to fix the battery, which can prevent the battery from moving during testing and ensure the accuracy of the test. Then, the testing component 30 drives the testing clip 342 on the testing unit 34 to clamp the battery testing end to test the battery. The contact area between the testing clip 342 and the battery testing end is increased to improve the stability of the test. Furthermore, with multiple locking positions 25 and multiple testing units 34, multiple batteries can be tested at the same time, which improves the efficiency of the test and makes it highly practical.
[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
