During operation, the linear bearing 321 is driven to move along the variable-pitch rod 31 in a pneumatic and electric mode, when the interval between two cylindrical batteries 2000 is equal to the material separation interval, the limiting block 322 is just abutted to the limiting boss 323, and the limiting block 322 cannot continue to move due to the abutment of the limiting boss 323, at this time, the interval between two adjacent cylindrical batteries 2000 is equal to the material separation interval. When the first pitch-changing sucker assembly 30 moves to a preset position on the battery classification cycle line, the first pitch-changing sucker assembly 30 can directly release the cylindrical batteries 2000 because the spacing between the cylindrical batteries 2000 absorbed by the first pitch-changing sucker assembly 30 is the same as the spacing between the battery brackets, so that the cylindrical batteries 2000 enter the battery brackets.

In this embodiment, the spacing dimension corresponding to the spacing structure 32 is adapted to the material separation distance, and when the spacing structure 32 moves along the surface of the spacing rod 31, the battery suction structure 33 can be driven to move, so as to adjust the distance between the cylindrical batteries 2000 adsorbed by the battery suction structure 33, so that the distance between two adjacent cylindrical batteries 2000 is the same as the material separation distance, ensuring that the distance between the cylindrical batteries 2000 meets the production requirement, and facilitating the subsequent accurate release of the cylindrical batteries 2000 in the battery bracket.

In operation, the transplanting power portion 211 drives the vertical transplanting structure 22, the first and/or second variable-pitch sucker assemblies 30, 40, and the adsorbed cylindrical battery 2000 to move in a horizontal direction.

The auxiliary rail portion 212 may be a rail, or the like. The auxiliary guide rail part 212 is used for assisting the transplanting power part 211 to move along the horizontal direction, so that the transplanting power part 211 is uniformly stressed and is supported symmetrically and stably.
