Automatic assembly method and system for swing lever type positive and negative electrode pieces

Abstract

This invention discloses a CNC controlled cantilever type system for automatically assembling positive, negative poles sheets, and the method therefore. It includes: (a), taking the piled-up sheets out of the box, and then the sheets being separated, tested and put on the place where the assembling will be proceeded; (b), opening isolation film roll and putting it in right direction, distributing film between positive and negative film; (c), placing positive and negative sheets alternatively between the isolation film, and compacting them into a pile on a bench; (d), counting the numbers of the positive and negative sheets; (e), major-minor workbenches grasping the whole pile of assembly, and then being reset; (f), winding the whole assembly with isolation film, and cutting-off the film; (g), removing away the film roll, adhering the adhesive tape onto said assembly, making it keep the geometric shape, finally removing them one after another.

Description

technical field [0001] The invention relates to an automatic pole piece assembly method and system, in particular to a swing arm type automatic pole piece assembly method and system. The present invention can also be applied to automatic production equipment or product assembly units and assembly lines for rechargeable batteries, especially lithium ion batteries or capacitor energy storage components. Background technique [0002] In modern society, with the continuous expansion of the demand for green and environmentally friendly energy, the importance of rechargeable batteries, especially lithium-ion batteries, is becoming more and more prominent. However, the automation of the assembly process of rechargeable batteries, especially lithium-ion battery pole pieces, whose core components are the positive and negative pole piece assemblies stacked in insulating intervals, has lagged behind the development of the battery industry. For example, in some factories, the assembly ...

AI Technical Summary

Problems solved by technology

However, the automation of the assembly process of rechargeable batteries, especially lithium-ion battery pole pieces, whose core components are the positive and negative pole piece assemblies stacked at intervals insulated from each other, has lagged behind the development of the battery industry.

For example, in some factories, the assembly process of positive and negative electrodes is still done manually, which is always difficult to meet the current requirements for the output and quality of such products

At present, some large companies have provided a prototype of a reciprocating pole piece automatic loading machine controlled by PLC. Although there has been progress, there are still some shortcomings, mainly because the reliability is poor and the output is not high enough to meet the production requirements, which may cause Mistakes and some unexpected losses

Moreover, the demand for large-capacity rechargeable batteries, especially lithium-ion batteries, continues to increase, and the method and system for automatic loading of the cantilever-type batteries have not been fully utilized in the automation of the lithium-ion battery pole piece assembly process.
