[0020] This embodiment provides a lithium battery production test device, such as Figure 1-4As shown, it includes a detection frame 1, a limit block 2, a first detection block 3, a second detection block 31, an elastic member 6, a slider 71, a baffle 8, a rotating rod 9, a card plate 10 and a pull ring 11. The detection frame 1 is connected to the limit block 2 on one side, the limit block 2 is connected to the first detection block 3, and the detection frame 1 is connected to the second detection block 31. It also includes a contact rod 4 and an insulating sleeve 5. Two contact rods 4 are connected to the first detection block 3. The contact rod 4 passes through the upper part of the detection frame 1 and is covered with an insulating sleeve 5. The bottom of the second detection block 31 is connected to the slider 71. The detection frame 1 is opened for the slider 71 to slide The first slide groove 7 of the second detection block 31 is also connected to two contact rods 4, the upper end of the contact rod 4 is set as a ring, the two contact rods 4 pass through the upper part of the detection frame 1 and are covered with an insulating sleeve 5, and the upper part of the detection frame 1 is provided with a second slide groove 12 for the two contact rods 4 to slide, an elastic member 6 is connected between the slider 71 and the detection frame 1, a baffle 8 is rotatably connected to one side of the detection frame 1, a pull ring 11 is fixed to the baffle 8, a rotating rod 9 is rotatably connected to the detection frame 1, and a card plate 10 for clamping the baffle 8 is connected to the rotating rod 9. The rotating rod 9 and the card plate 10 are arranged in an L-shape as a whole.

[0021] When the device needs to be used, the staff first rotates the rotating rod 9, and the rotating rod 9 drives the card plate 10 to rotate so that the card plate 10 no longer blocks the baffle 8, and then pulls the pull ring 11 and rotates the baffle 8 to open one side of the detection frame 1, and places the lithium battery to be detected into the detection frame 1. One side of the lithium battery contacts the first detection block 3, and the other side of the lithium battery pushes the second detection block 31. The slider 71 of the second detection block 31 moves along the first slide groove 7, and the elastic member 6 is deformed. At the same time, the contact rod 4 on the second detection block 31 slides along the second slide groove 12, and the insulating sleeve 5 also moves accordingly. When it is pushed to a position suitable for the size of the lithium battery, the second detection block 31 no longer moves, and the elastic member 6 is compressed, The slider 71 on the detection block 31 applies elastic force, so that the second detection block 31 is in close contact with the lithium battery, pulls the insulating pull ring 11 to rotate the baffle 8, the outer side of the baffle 8 is set to an insulating material, closes the detection frame 1, and then rotates the card plate 10.

Then the staff holds the insulating sleeve 5 and connects the detector with the circular ring at the upper end of the contact rod 4. The first detection block 3 and the second detection block 31 transmit the detection information to the detector, so that the lithium battery can be tested. The baffle 8 can prevent the staff from touching the energized lithium battery during the detection process, and play a protective role in the process of detecting the lithium battery.

The refrigerator 14 cools the cold pipe 13, and the air is cooled, so that the inside of the test frame 1 is cooled in time. After the test is completed, the refrigerator 14 is turned off, and the cold pipe 13 no longer cools the inside of the test frame 1.
