Title:
POLE PIECE CUTTING AND CONVEYING DEVICE AND LAMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/092910
Kind Code:
A1
Abstract:
The present application relates to the technical field of lithium battery production equipment, and in particular, to a pole piece cutting and conveying device and a lamination 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 cuts a pole piece strip discharged by the pole piece unwinding mechanism to obtain pole pieces. 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 connection positions of the feeding section and the backflow section are a feeding station and a discharging station, respectively. 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 lamination system, the pole pieces are picked up, conveyed and released by means of the conveying trolleys, the transfer offset is small, the transfer process is small, and sheet cutting, transportation and lamination can be efficiently and accurately carried out.
