Battery lamination stacking machine of lithium-ion power battery

Abstract

The invention relates to the field of battery manufacturing mechanical technique, and provides a battery lamination stacking machine. The battery lamination stacking machine comprises a lamination platform machine, a pole piece feeding box mechanism, a secondary positioning mechanism, a lamination taking mechanical arm, a multiple lamination detection mechanism, a membrane unreeling mechanism, a membrane reeling mechanism, a membrane cutting mechanism, a rubberizing mechanism, a battery transfer mechanism and a battery conveyor belt. The lamination taking mechanical arm comprises a positive lamination taking mechanical arm and a negative lamination taking mechanical arm. The positive lamination taking mechanical arm and the negative lamination taking mechanical arm each comprise two groups of stand-by sucker and two groups of lamination sucker, and can realize simultaneous lamination stacking of a lamination mechanism A and a lamination mechanism B, and improve the efficiency of battery assembly.

Description

Technical field [0001] The invention relates to the technical field of battery manufacturing machinery, in particular to a machine for producing lithium-ion power battery cells. Background technique [0002] At present, in the manufacturing process of large-scale lithium-ion power batteries, a stacking machine is usually used to assemble the positive and negative plates of the lithium-ion battery cell and the separator into a Z-shaped lamination to make the cell. In the commonly used lithium ion power cell stacking machine, the left and right picking mechanical arm mechanism of the equipment picks up the pole pieces in the positive and negative two troughs, and after precise positioning by the secondary positioning table, they alternately place them on the stacking table. The stacking table moves around the two robotic arms to coordinate with the actions of the two robotic arms, and makes the isolation film form a Z-shape to separate the positive and negative plates; the device c...

Problems solved by technology

[0003] However, the Z-shaped stack assembly structure of the battery determines the working mode and efficiency of the stacker when making batteries; with the further use of fuel-based non-renewable energy, there is a shortage of supply and pollution to the environment, which has led the market to The demand for large-scale lithium-ion power batteries is soaring, and the structural production efficiency of the current stacking machine is difficult to meet the market demand

If two sets are installed, more workshop locations and operators will be required, resulting in a waste of resources
