The process of pressing the cell at least includes: opening the lower jaw and moving it to the position of the cell, and then clamping the cell so that the lower end face of the cell is fixed on the lower jaw and the side of the cell is close to the inner side of the lower jaw. , the upper pressing plate moves downwards under the driving of the first driving member to approach the battery cells and compress the loose battery cells until the compaction stops. After the pressing of the cell is completed, the tape is unwinded from the unwinding assembly, and passes through the transition roller, the upper pulling belt assembly and the lowering belt assembly in turn. Length demand adjustment), pull up the belt assembly to clamp the tape, and move the suction assembly to the direction of the tape until the suction hole can absorb the tape. At this time, the cutter driver drives the cutter to cut the tape, and pulls down the belt assembly to release the end of the tape. At this time, the tape is completely adsorbed on the upper tape suction block and the lower tape suction block in the glue suction assembly, and is driven by the second direction driver to move to the direction of the cell until the tape is attached to the cell, and the sticking is completed. The glue works, so that the cells can be stably maintained in a compacted state, which reduces the thickness of the cells, thereby solving the problem that the height of the workshop limits the number of hot-pressed cells in the prior art, and improving the overall performance of the cells. Preparation efficiency.

The above are only the embodiments of the present invention, and are not intended to limit the scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, All are similarly included in the scope of patent protection of the present invention.
