[0002] In recent years, lithium batteries have become the mainstream of power battery development. Lithium batteries have the characteristics of light weight, large energy storage, and no pollution. They are also a chemical battery with lithium metal salt as electrolyte.

[0003] Generally, lithium batteries undergo charge and discharge testing before leaving the factory to ensure proper function. For example, to charge a lithium battery, you first place the battery in a carrier and align the probe tip with the battery's electrodes. Once you've ensured the probe tip is firmly in contact with the battery's electrodes, you can then apply charging current to the battery.

[0004] Among them, square battery test probes are important basic components in square lithium-ion power battery formation and capacity grading equipment. Generally, when testing square lithium-ion power batteries, the same number of probes arranged in a rectangular array are required for testing. During the test, the probes contact the corresponding probes. However, due to the large number of probes, once the probe positions are offset and mismatched, inaccurate detection will occur, affecting the normal testing of the lithium battery, which will not only waste testing resources but also waste testing time.

[0028] The probes on one type of probe module 1 are arranged in a rectangular array, and the reference positions of the probes on the bottom trace paper 4 and the upper trace paper 6 are also arranged in a rectangular array. The reference positions of the probes on the bottom trace paper 4 and the upper trace paper 6 correspond one-to-one to the probes on the probe module 1.

[0029] The connection relationship between the bottom trace paper 4, the middle carbon paper 5 and the upper trace paper 6 is that the bottom trace paper 4 is bonded to the outer wall of the top plate 23. After the middle carbon paper 5 is bonded to the upper trace paper 6, the middle carbon paper 5 is bonded to the bottom trace paper 4.

[0030] To facilitate the connection between the support plate 3 and the support base 2, the upper surface of the support base 2 is provided with several positioning pins 20. The support plate 3 is provided with several positioning holes 31. The positioning pins 20 extend through the positioning holes 31 to position the support plate 3. The bottom trace paper 4, the intermediate carbon paper 5, and the upper trace paper 6 are each provided with through-holes at positions corresponding to the positioning holes 31. This allows the positioning pins 20 to pass through the through-holes in the bottom trace paper 4, the intermediate carbon paper 5, and the upper trace paper 6 to avoid interference.

The plurality of probes 12 press down at the reference position of the probes on the upper trace paper 6. The actual positions of the plurality of probes 12 are left on the lower trace paper 4 via the intermediate carbon paper 5. The left indentation positions of the plurality of probes 12 are compared with the reference positions of the probes on the lower trace paper 4 to determine whether there is any error in the position of the probes 12.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
