This detection method may result in non-contact or poor contact, and may mismeasure a short-circuited battery cell as a qualified product, but there are still the following problems:

[0003] During use, the lithium battery cell still needs to be manually placed on the device, and the detection process cannot be completed on the conveyor belt, affecting the detection efficiency. Summary of the Utility Model

[0004] Based on the existing technical problems in lithium battery cell detection, the utility model proposes a lithium battery cell detection device.

[0005] A lithium battery cell detection device proposed by the utility model includes a conveyor belt. Conveyor belt frames are arranged on both sides of the conveyor belt. Vertical rods are fixedly installed on both sides of the conveyor belt frames. An adjusting clamping mechanism is arranged in the middle of one of the vertical rods, and detection mechanisms are arranged between the two vertical rods; the adjusting clamping mechanism realizes the clamping and adjusting action of the lithium battery cell conveyed above the conveyor belt, and the detection mechanism realizes the short-circuit detection action of the lithium battery cell conveyed above the conveyor belt.

[0006] Preferably, the adjusting clamping mechanism includes a screw rod. A sliding groove is opened in the middle of the vertical rod.

Also, since the slider is slidably inserted into the inner side wall of the sliding groove, the slider is limited to slide up and down in the sliding groove.

[0008] Preferably, support blocks are symmetrically and fixedly installed on one side of the slider. On one side of the two support blocks, a first support plate is fixedly installed. In the middle of the first support plate, a first rotating shaft is rotatably connected through a ball bearing.

At the lower end of the cross bar, a telescopic cylinder III is fixedly installed. The detection block is fixedly connected to the telescopic end of the telescopic cylinder III. At the lower part of the detection block, a detection probe is fixedly installed.

[0015] Through the above technical solution, under the action of the telescopic cylinder III, the detection block can move up and down, so that the detection probe contacts the detection contact of the lithium battery cell.

[0016] Preferably, the surface of the conveyor belt is annularly and arrayed with supporting columns, and an anti-slip surface is provided on the upper part of the supporting columns.

[0017] Through the above technical solution, by setting the supporting columns, part of the lithium battery cell is suspended, so that the lower supporting plate can extend under the lithium battery cell under the action of the telescopic cylinder I, which is convenient for clamping the lithium battery cell. Moreover, an anti-slip surface is provided on the upper surface of the supporting columns to increase the friction force and prevent the lithium battery cell from slipping on the supporting columns.
