Applicable to Z-shape laminating fitting of cathode, anode and separator of lithium battery core; Both mechanical arms pick up pole pieces from troughs at cathode and anode through fore-and-rear motion. After secondary positioning, the arms discharge alternately on the laminating table which moves left and right to make the separator form Z-shape winding. In this way, laminating assembly of a whole core can be realized to form an entire core. Automatically confirm the need of taking material and remember it. Secondary positioning function to ensure precision Separator unwinding constant tension control, automatic deviation rectifying, regular end surface Quantity for lamination set through the touch screen, with memory function Imported PLC automation control, man-machine conversation through touch screen Perfect alarm function and safety protection performance Function of preventing heavy pole piece absorption.
