[0027] Among them, the movable probe seat 3 and the sliding probe support 4 can conveniently adjust the distance between them and the cylindrical battery cell support seat 2, ensuring that the tooling can adapt to batteries of different sizes or shapes, increasing the versatility and convenience of the test.
[0028] By pushing the moving block 42 with one hand to compress the spring column 43, and then the reaction force of the spring column 43 makes the corresponding voltage internal resistance tester probe press against one end of the cylindrical battery cell, so as to achieve one-handed operation and detection, which not only improves the test efficiency but also reduces the operation difficulty, thereby timely and accurately grasping the product voltage internal resistance situation, timely optimizing the production process and improving product quality.
[0029] The reaction force of the spring column 43 can ensure that the contact between the probe and the battery cell is tight and stable. Such stable contact can reduce test errors and improve test accuracy.
[0030] In this embodiment, the cylindrical battery cell support seat 2 includes a support platform 21, and the support platform 21 is provided with an arc-shaped groove 211 for placing the cylindrical battery cell. The support platform 21 is fixed to the inspection table 1 by bolts.
