Problems solved by technology

However, for the stacking of four-layer units, traditional manipulators are still used to absorb, transfer, and stack. The cycle time of each stacking is still long, the stacking efficiency has not been greatly improved, and the accuracy of stacking is not high. , the pole piece is easily damaged, and the quality of the lamination is difficult to guarantee

Abstract

The invention discloses a lithium battery stacking device, which comprises a transmission part, and the rear side of the transmission part is sequentially provided with a folding part, a heat pressing roller, a transfer part and a stacking part along the material flow direction; the folding part is arranged in the transmission part , the folded part is provided with a folding plate; the transfer part is located below the hot pressing roller, the transfer part is provided with a linear motion mechanism for the transfer part to reciprocate up and down, and the transfer part is provided with a transmission mechanism and a flattening mechanism , the transmission mechanism is located in the pressing plate mechanism; the folding part is arranged under the transfer part, and a lamination platform reciprocating left and right is arranged in the folding part, and pressing plates are provided on the left and right sides of the upper end surface of the lamination platform. The device does not have the working steps of manipulators to pick up and transfer the pole pieces, and the transfer of the pole pieces can be realized through the unit transfer assembly. Manufacturing efficiency has been effectively improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing equipment, in particular to a lithium battery lamination device. Background technique [0002] The battery cell of a lithium-ion battery is composed of a positive pole piece, a diaphragm, and a negative pole piece. At present, lithium batteries mostly use a laminated battery cell: the diaphragm is folded in a "Z shape", and then the positive and negative pole pieces are inserted respectively. [0003] However, the preparation process of this type of battery cell is complicated, requiring a lot of time and energy to perform the sequential stacking process, it is difficult to realize mechanized operation, and the production efficiency is low. In the actual production process, the efficiency of performing lamination is mostly about 1 second / piece, and the battery cell is composed of several positive and negative electrodes stacked, so the current "Z-shaped" lamination method is alr...
