Abstract

The invention discloses a lithium ion battery cell packet preparation method, including the following steps: pole piece material is made into negative pole pieces, and the negative pole pieces are transmitted to a negative pole sorting machine; qualified negative pole pieces are selected from the negative pole pieces and transmitted to a lamination stacking machine; the pole piece material is made into positive poles pieces, and the positive pole pieces are transmitted to a positive pole sorting machine; qualified positive pole pieces are selected from the positive pole pieces and transmitted to a positive pole bag machine; the qualified positive pole pieces are made into positive pole bags, and the positive pole bags are transmitted to the lamination stacking machine; lamination stacking is carried out on the positive pole bags and the qualified negative pole pieces by the lamination stacking machine, thus obtaining the cell packet. The invention also discloses a lithium ion battery cell packet preparation system. The invention comprises a negative pole processing machine, a split pole sorting machine, a lamination stacking machine, a positive pole bag machine, a positive pole sorting machine and a positive pole processing machine which are arranged in sequence, transmission equipment is arranged between each two equipment, thus cell packet can be prepared without manual operation and reliability and stability of the cell packet are improved.

Description

technical field [0001] The invention relates to a lithium ion battery, in particular to a preparation method and system for a lithium ion battery core pack. Background technique [0002] At present, the manufacturing methods of large-scale lithium-ion power battery cells are mainly semi-automatic cell manufacturing and manual cell manufacturing. The semi-automatic production of battery cells mainly includes single-machine sheeting, single-machine sorting, single-machine bagging, and single-machine lamination. The loading and discharging between each machine is completed by manual operation; the disadvantages of the existing semi-automatic core package preparation system are: During the production process, people participated in some of the work, which posed a hidden danger to the reliability of the core package. Because of excessive handling, it will affect the alignment of the cell; manual contact with the pole piece and diaphragm will affect the performance of the cell. ...
