Die for linear stretching and shell punching of aluminum-plastic film for polymer lithium ion battery

Abstract

The utility model relates to an aluminum plastic film linear stretching and shell punching die for polymer lithium ion batteries, which comprises an unloading template, a convex template, a punching head, an air bag punching head, a lower driving mechanism and an upper driving mechanism, when the shell is punched, an aluminum plastic film is prevented from being arranged on the unloading template, a first vacuum air hole is used for exhausting air, the aluminum plastic film is fixed, and the upper driving mechanism is arranged on the convex template; the lower driving mechanism drives the discharging die plate to move upwards to be attached to the male die plate, then the upper driving mechanism drives the punching head and the air bag punching head to move downwards to conduct shell punching, shell punching is conducted in the mode, an aluminum plastic film cannot move in the shell punching process, and the finished product rate of shell punching is higher.
