In the production process of the single battery, the formation and grading of the single battery is an extremely important link in the production process, wherein after the formation and grading of the single battery are finished, the single battery needs to be detected in order to ensure the production quality of the single battery.

The inventor finds that in the existing production line, the battery cells are generally subjected to formation and partial volume in batch, however, when the number of the battery cells in batch changes, the formation and partial volume needle beds of the battery cells need to be exchanged, so that the battery cell detection device also needs to adjust the number of probes of the battery cell detection device according to the number of the battery cells in the battery cell tray to meet the requirement of batch detection of the battery cells. However, in the prior art, when the number of the single batteries is changed, the single battery detection device needs to manually adjust each probe mechanism after shutdown, so that the number of the single battery detection device used for detecting the single battery probe mechanisms is consistent with the number of the detection channels, thereby realizing the model change of the single battery detection device, however, the single battery detection device with the structure needs longer operation time in the process of model change, and needs to be stopped for adjustment, thereby reducing the detection efficiency of the single battery, and affecting the starting rate of the production line, and further being not beneficial to improving the production efficiency and the production rhythm of the single battery.

Based on the above consideration, in order to solve the problem that the detection efficiency of the battery cell is low after the formation and partial capacity is finished, the inventor conducts extensive research, and designs a probe mechanism, wherein the probe mechanism is provided with a shell and a probe, the probe is movably inserted into the shell along a first direction, the probe is provided with a first position for detecting the battery cell and a second position for stopping detecting the battery cell in the first direction relative to the shell, and by arranging an adjusting component between the shell and the probe, the adjusting component can adjust the position of the probe relative to the shell, so that the probe can be switched between the first position and the second position.

After battery monomer ization becomes the partial volume, probe mechanism can adjust the position of probe on the first direction through adjusting part to make the probe switch between primary importance and second place, thereby realized that probe mechanism surveys and stops to switch between two modes that battery monomer surveyed to battery monomer, in order to satisfy the actual production needs.
