Abstract

The invention discloses a high-speed die cutting machine for a lithium battery pole piece. The machine comprises a material tray unreeling mechanism, a plurality of guiding rollers, a centring device, a servo pressure machine for molding, a material strip traction mechanism, a cutter assembly for cutting a material strip and a material sheet conveying system; the servo pressure machine comprises an upper template, a lower template, a mounting plate and a machine base which are used for molding the material sheet, a plurality of guiding posts, a cam mechanism, a connection fixing mechanism for connecting the cam mechanism and the guiding posts and a driving motor; an air cylinder is also arranged under each guiding post; telescopic arms of the air cylinders are vertically arranged and prop against the guiding posts; the air cylinders are matched with a bulging mechanism in a shrinkage process and are used for buffering a descending process of the guiding posts. By the arrangement of the air cylinders, the descending processes of the mounting plate and the guiding posts are buffered to counteract a gravity influence of the mounting plate in a quick descending process, and the stability of the equipment is maintained, so that the high-speed operation requirement is met.

Description

technical field [0001] The invention relates to the technical field of high-speed die-cutting machines for lithium battery pole pieces, in particular to a high-speed and stable die-cutting machine. 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 the mounting plate, the mounting plate and the guide column ...
