(54) POLE PIECE CUTTING AND CONVEYING DEVICE AND LAMINATION SYSTEM


(57) This application relates to the field of lithium battery production equipment, especially to a pole piece cutting-conveying apparatus and a stacking system. The pole piece cutting-conveying apparatus 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 unwound by the pole piece unwinding mechanism to obtain pole pieces; the pole piece conveying mechanism comprises an annular infeed track and a plurality of conveying trolleys; the annular infeed track comprises an infeed segment and a return segment which are attached to one another end-to-end, the end-to-end-attached positions of the infeed segment and the return segment are respectively act as an infeed station and a outfeed station, and each of the conveying trolleys is able to pick up a pole piece at the infeed station and release it at the outfeed station. The stacking system comprises said pole piece cutting-conveying apparatus. The pole piece cutting-conveying apparatus and the stacking system carry out pick-up, convey and release of the pole pieces by the conveying trolleys such that there is little conveying deviation and less conveying processes, so as to carry out cutting, conveying and stacking of the pole pieces efficiently and precisely.
