This equipment completes the whole roll material rolling process after coating, manuallyinstalls the material to the unwinding device of the equipment, the unwinding mecha-nism adopts a 3-inch single-axis manual rewinding mode, the process uses a doubleclosed-loop speed control mode material for correction tension control, and then entersthe front flattening mechanism to carry out strong pressure on the pole piece, and afterphase pressure, the post-flattenin g and thickness measuring mechanism are carriedout, CCD detects the defects of the pole piece, and finally enters the rear belt mecha-nism for winding.
