Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a lithium-ion battery roller drop test fixture. Background Technology

[0002] In modern industrial production and quality control, product safety and reliability are paramount. To ensure products maintain their functional and structural integrity during transportation, use, or accidental drops, the roller drop test has become a widely used testing method. This test assesses a product's impact resistance and structural integrity by simulating drop scenarios that products might encounter in real-world use.

[0003] Traditional drop testing methods often rely on simple free-fall experiments, requiring no fixture support. However, this method cannot fully simulate the various complex situations encountered in real-world use. Roller drop testing, on the other hand, involves rotating a roller to drop the product from multiple angles and directions, more closely mimicking the real-world environment and providing more accurate and comprehensive test data.

[0004] However, existing roller drop test fixtures still have some shortcomings. Most of the test fixtures are complicated and cumbersome to operate, which can easily affect the test efficiency and accuracy. Furthermore, they are difficult to adapt to different product specifications, and their application range is relatively limited. Utility Model Content

[0005] The purpose of this utility model is to provide a lithium-ion battery roller drop test fixture to solve the problems that most existing test fixtures are complicated and cumbersome to operate, which can easily affect the testing efficiency and accuracy, and are difficult to adapt to different product specifications, thus limiting their applicability.

[0006] A lithium-ion battery roller drop test fixture includes a fixture main board with a mounting frame on it. Multiple second screw holes are provided on the fixture main board around the mounting frame. A tab fixing fixture is provided at the upper end of the mounting frame. A detection groove is provided within the mounting frame below the tab fixing fixture. A spring is provided on the side wall of the mounting frame below the detection groove, and a limit groove is fixedly connected to the end of the spring. A matching fixture cover plate is provided on the top of the fixture main board, and first screw holes corresponding one-to-one with the second screw holes are provided on the fixture cover plate.

[0007] Preferably, the clamp cover plate has an observation port on its upper part, and foam is provided on the surface of the clamp cover plate that contacts the clamp main plate.

[0008] Preferably, the surface of the clamping block that contacts the battery is provided with a wear-resistant layer, and the four corners of the mounting frame are provided with limiting grooves.

[0009] Preferably, both the clamp cover and the clamp main plate are made of transparent material.

[0010] The advantages of this utility model are as follows: This utility model provides a lithium-ion battery roller drop test fixture, which can fix batteries of different sizes by setting springs, thus expanding the applicability of the fixture. The electrode fixing fixture uses electrode fixing fixtures to fix the electrode electrodes and prevent the electrodes from deforming during the test. By setting detection grooves and observation ports, the battery voltage and internal resistance can be detected during the test. The operation is simple and does not require disassembly of the fixture, which enhances the convenience of the fixture. The test fixtures are all made of transparent materials, which makes it easy to observe the battery condition during the test, thus improving the test efficiency and accuracy.
