Lithium battery pole piece double-strip high-speed die cutting machine

Abstract

The invention discloses a lithium battery pole piece high-speed die cutting machine, and relates to the technical field of lithium battery pole piece high-speed die cutting machines. The lithium battery pole piece high-speed die cutting machine comprises a tray unwinding mechanism, multiple guide rollers, rectifying mechanisms, a servo press for molding pole pieces and pole lugs, strip traction mechanisms, cutter modules for cutting strips, and a piece conveying system; the tray unwinding mechanism comprises two independent unwinding shafts; each unwinding shaft is corresponding to one strip, one rectifying mechanism, one strip traction mechanism and one cutter module; each rectifying mechanism comprises two rectifying sensors and a rectifying device; rectifying sensors are positioned in different positions of a strip advancing direction; and straight lines of the rectifying sensors on the two rectifying mechanisms are arranged in parallel to prevent tilting of the strips due to axial movement of the unwinding shafts and to guarantee parallelism of the two strips.

Description

technical field [0001] The invention relates to the technical field of a high-speed die-cutting machine for a pole piece of a lithium battery, in particular to a high-speed die-cutting machine for a double-material belt of a pole piece of a lithium battery. Background technique [0002] The existing die-cutting machine system for lithium battery pole pieces includes a material tray unwinding mechanism, several guide rollers, a deviation correction mechanism, a servo press for forming, a strip traction mechanism, a cutter assembly for cutting the strip, and a strip Conveyor system. [0003] Among them, the structure of the servo press is relatively simple, mainly including an upper template, a lower template, a mounting plate, a machine base, a number of guide columns, a cam mechanism, a connecting and fixing mechanism connecting the cam mechanism and the guide column, and a driving motor, and the lower template is fixed on the machine base. , the upper template is fixed on ...
