Abstract

The invention relates to a pole piece processing device and a lamination machine. The pole piece processing device comprises a pole piece bearing part, a positioning mechanism, a deviation rectifying mechanism, a translation mechanism and a detection mechanism; the positioning mechanism is configured to position the pole piece borne on the pole piece bearing part; the deviation rectifying mechanism is configured to drive the pole piece bearing part to move according to the positioning information of the positioning mechanism; the translation mechanism is configured to drive the pole piece bearing part to pass through the detection mechanism; and the detection mechanism is configured to continuously detect the pole pieces passing through the pole piece bearing part, and the pole pieces after detection are sent to the next process for lamination. The pole piece processing device can automatically complete detection of the pole piece, and the detection efficiency is improved. According to the lamination machine, the edge of the cut pole piece is automatically detected by configuring the pole piece processing device, so that the sampling inspection frequency of the pole piece can be improved, and the number of battery cells between two times of sampling inspection is reduced; and after the pole piece is detected to have problems, the number of reworked battery cells is relatively low, and the production efficiency of the battery cells can be improved.

Description

technical field [0001] The invention relates to production equipment for lithium battery cells, in particular to a pole piece processing device and a stacking machine. Background technique [0002] In the production process of laminated lithium battery cells, the pole pieces will be cut by a cutter. Due to cutter loss or other reasons, burrs will appear on the edge of the pole piece after cutting. The presence of burrs may cause the cell to puncture the diaphragm in the later hot pressing process and cause a short circuit, so a pole piece edge detection process will be set up. [0003] The traditional pole piece edge detection method is to manually randomly select a piece of cut pole piece at regular intervals, and manually inspect it under a microscope. If there is any problem, the cells from the previous inspection to the current inspection will be inspected or even reworked. Due to the large number of reworked cells in this detection method, the production efficiency of...
