Embodiment 1

[0048] combine Figure 1 to Figure 4 As shown, the embodiment of the present application provides a pole piece cutting and conveying device including a pole piece unwinding mechanism, a pole piece cutting mechanism and a pole piece transportation mechanism arranged in sequence, wherein the so-called sequential arrangement means along The unwinding direction, that is, the direction in which the pole piece strips are delivered, is set sequentially, so that the pole piece strips released by the pole piece unwinding mechanism are successively delivered to the pole piece cutting mechanism and the pole piece transport mechanism.

[0049] The pole piece cutting mechanism is used to cut the pole piece material tape released by the pole piece unwinding mechanism to obtain pole pieces. Wherein, the pole piece unwinding mechanism can adopt the existing equipment with the pole piece unwinding function, for example, the pole piece unwinding mechanism includes a discharge roller and a drivi...

Abstract

The invention relates to the technical field of lithium battery production equipment, in particular to a pole piece cutting and conveying device and a piece stacking system. The pole piece cutting and conveying device comprises a pole piece unwinding mechanism, a pole piece cutting mechanism and a pole piece conveying mechanism which are arranged in sequence, the pole piece cutting mechanism is used for cutting the pole piece material belt unwound by the pole piece unwinding mechanism to obtain a pole piece; the pole piece conveying mechanism comprises an annular feeding track and a plurality of conveying trolleys; the annular feeding track comprises a feeding section and a backflow section which are connected end to end, the end-to-end connecting positions of the feeding section and the backflow section are a feeding station and a discharging station respectively, and each conveying trolley can pick up the pole pieces at the feeding station and release the pole pieces at the discharging station. The lamination system comprises the pole piece cutting and conveying device. According to the pole piece cutting and conveying device and the piece stacking system, the pole pieces are picked up, conveyed and released through the material conveying trolley, the transfer offset is small, the transfer process is few, and piece cutting, conveying and piece stacking can be efficiently and accurately conducted.

Description

technical field [0001] The present application relates to the technical field of lithium ion production equipment, in particular to a pole piece cutting and conveying device and a stacking system. Background technique [0002] Square lamination technology is one of the lithium-ion battery manufacturing technologies. The speed and accuracy of the lamination technology directly determine the production capacity of the lithium-ion production line and the cost of cell manufacturing. [0003] The lamination speed of the current lamination equipment is relatively slow. In order to meet the production capacity, there is a large demand for the number of equipment, resulting in a large footprint, high purchase costs, high maintenance costs and energy consumption, which is not conducive to energy conservation and environmental protection. Contents of the invention [0004] The purpose of this application is to provide a pole piece cutting and conveying device and a lamination system...
