Battery stacking mechanism and stacking method thereof

Abstract

The battery stacking mechanism includes a positive electrode mold, a driving roller 1, a driving roller 2, a driving roller 3, a hot pressing module, a negative electrode mold, a rolling pin group, and a negative electrode suction plate. The driving roller 1 is arranged in front of the positive electrode mould, and the driving roller 2 and The position of driving roller 3 relative to driving roller 1 is set up and down respectively, the driving direction of the driving roller 1, driving roller 2 and driving roller 3 is towards the hot pressing module, and the rolling needle group is arranged behind the hot pressing module, and the rolling needle group Set at the vacuum winding lamination position, the negative electrode mold and the negative electrode suction plate are respectively arranged on both sides of the needle roll group, the needle roll group can rotate 360 ​​degrees around its central axis, and the negative electrode suction plate can move towards the needle roll group . In the battery stacking method, the positive electrode separator assembly is hot-pressed first, and then sent to the vacuum winding stacking station, where the negative electrode is stacked, and the positive electrode separator assembly and the negative electrode sheet are stacked layer by layer through vacuum winding. The invention has the advantages of simple structure, reasonable configuration, stable operation and extremely high efficiency.

Description

【Technical field】 [0001] The invention relates to the field of electronics, in particular to a battery stacking mechanism and a battery stacking method thereof. 【Background technique】 [0002] With the further use of fuel-based non-renewable energy, supply shortages and environmental pollution have led to a sharp increase in the market demand for large-scale lithium electronic power batteries. The positive and negative plates and the diaphragm are assembled in Z-shaped laminations to make batteries. The common lamination method in the prior art is the lamination table moving back and forth. The left and right two picking mechanical arm mechanisms of the lithium battery lamination equipment pick up the pole pieces in the positive and negative troughs, and then position them on the secondary positioning workbench. Finally, the material is alternately discharged on the stacking table. The stacking table moves left and right between the two mechanical arms to cooperate with the...

Problems solved by technology

In the prior art, this kind of equipment can only produce one battery cell at a time, and the lamination speed can only be between 1.5--2.0s / pcs according to the size of the pole piece. It is difficult to have a greater breakthrough in efficiency, the efficiency is too low, and the lamination The table goes back and forth between the positive and negative poles, the structure is complex, and the operation is unstable. The left and right two piece-picking mechanical arm mechanisms pick up the pole pieces in the positive and negative two troughs, and they need to be positioned by the secondary positioning workbench and placed alternately on the stacking table. material, low efficiency, and easy to absorb multiple pieces, the device structure is too complicated

The production efficiency of the prior art stacking machine is really difficult to meet the market demand
