Description

Technical Field

[0001] The invention relates to the field of battery manufacturing, and in particular to a battery follower mechanism adapted to battery charging and discharging. Background Art

[0002] During the production process of lithium batteries, the batteries need to be continuously charged and discharged to test and adjust battery performance. This process is also called the charge and discharge capacity of lithium batteries.

[0003] In order to ensure stable and reliable charging and discharging of lithium batteries, it is necessary to pay attention to the stability of the pressing between the battery pole and the probe, that is, the projection position of the probe and the lithium battery pole in the vertical direction must coincide. If the position of the probe and the lithium battery pole deviates, the probe will not be able to effectively contact the lithium battery pole, affecting the charging and discharging of the lithium battery.

[0004] Theoretically, when the probe queue and the lithium battery queue are facing each other, the lithium battery and its corresponding probe should be facing each other. However, in the actual production process, there are errors in the thickness of the lithium battery, the size of the separator, and the thickness error caused by the expansion of the lithium battery due to internal chemical reactions during charging and discharging. In particular, the above errors will accumulate in the lithium battery queue, resulting in the deviation of the lithium battery far from the contact point and its corresponding probe to a degree sufficient to affect the effective charging and discharging of the lithium battery.

[0005] The thickness and dimensions defined by each battery manufacturer are different. Existing equipment is a fixed structure, so the equipment must be redesigned to accommodate different thicknesses. It is not flexibly compatible with batteries of other thicknesses.

[0006] The Chinese patent specification with publication number CN 219371107 U reduces the position reference coverage of the lithium battery queue and the probe assembly from the entire queue to the length of a probe assembly by positioning equalization, thereby reducing the accumulation of battery swelling and thickness errors. However, battery swelling and thickness errors still accumulate within the range of the probe assembly. When the swelling and thickness errors between individual batteries are large, the effect of aligning the probe with the lithium battery's tabs still needs to be improved. Summary of the invention

[0007] The present invention aims to overcome the above problems of the prior art and proposes a battery follower mechanism.
