Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery testers, in particular to a lithium ion battery core tester. Background Art

[0002] Lithium battery testers are mainly used to measure the performance, capacity, internal resistance and other parameters of lithium batteries. They can help determine the health of the battery, evaluate its service life and predict possible failures. In the field of battery recycling, lithium battery testers can help determine the quality and performance of recycled batteries, thereby deciding whether to further process or recycle them.

[0003] The prior art discloses a patent application number "CN202222673359.8", which is a battery cell testing instrument used for lithium battery performance testing, including a battery cell testing instrument and a shell. By setting a space block, a connecting block, a fixing device and a transmission device, the fixing device cooperates with the interior of the space block and the interior of the connecting block to fix the space block and the connecting block, thereby fixing the battery cell testing instrument and the shell. The transmission device and the fixing device cooperate to allow the two fixing rods to be moved out of the interior of the connecting block, thereby separating the space block from the connecting block, thereby realizing the separation of the battery cell testing instrument from the shell, and then carrying out maintenance.

[0004] The battery cell testing instrument can only realize quick disassembly and assembly for inspection and maintenance. However, in actual use, since most lithium-ion battery cell testers directly test the battery cell tabs of lithium-ion batteries, the lithium-ion batteries are easily subjected to force and shake and displaced. In this way, the battery cell tester cannot accurately contact the battery cell tabs, resulting in a certain impact on the test results, thereby affecting the detection effect of the battery cell tabs and being not conducive to the use of the lithium-ion battery cell tester.

[0033] The working principle of a lithium ion battery cell detector provided by the utility model is as follows:

[0034] By placing the lithium-ion battery 10 between the first movable clamping plate 7 and the second movable clamping plate 8, the first springs 9 at the two movable clamping plates will be stretched at this time, so that the elastic force of the first springs 9 can be used to clamp and fix the lithium-ion battery 10, thereby ensuring the stability of the lithium-ion battery 10 during detection. Then, the electric push rod 12 is started, and the electric push rod 12 will drive the horizontal plate 14 at the circular plate 13 to move downward, so that the pressing block 16 equipped with the second spring 15 will be adaptively squeezed and fixed to the top of the pressing block 16, so as to further fix the lithium-ion battery 10, and ensure that the battery cell detector can accurately contact the battery cell tab 11 of the lithium-ion battery 10, so as to prevent the lithium-ion battery 10 from being easily subjected to force and shaking and displacement, thereby improving the detection effect of the detector;

[0035] By starting the No. 1 servo motor 19, the output shaft of the No. 1 servo motor 19 can drive the active gear rotating rod 18 to rotate, and then the active gear rotating rod 18 will also drive the driven gear rotating shaft 3 to rotate, so that the multiple tooling seats 5 on the disc 4 can be moved to the detector body 30 in sequence, so that multiple lithium-ion batteries 10 can be connected and detected, further improving the detection efficiency, and then the output shaft of the No. 2 servo motor 23 is used to drive the threaded shaft 22 to rotate, so that the lifting plate 24 on the threaded shaft 22 will move downward and allow the detector body 30 of the detector body 30 to detect the battery cell pole ear 11. At this time, the downward movement force will drive the first connecting seat 26 and the first rotating plate 27 and the second rotating plate 28 at the second connecting seat 29 to rotate relative to each other, and at the same time, the third spring 32 will be compressed, so that the detection force of the detection probe 31 can be weakened, so as to protect the detection probe 31 and allow the detection probe 31 to be used safely and reliably.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
