Punching machine for outer package aluminum plastic film of soft packing lithium battery

Abstract

The invention discloses a punching machine for an outer package aluminum plastic film of a soft packing lithium battery. The punching machine comprises a machine frame, a mounting frame, a guide rod, a pressing rod, a first electric push rod, a positioning block, a female mold, a male mold, a supporting unit, a lifting mechanism and a second electric push rod, the top of the machine frame is rotationally connected with a two-way screw rod, the corresponding threaded section of the two-way screw rod is in threaded connection with a transmission nut, the mounting frame is fixed to the side face of the top of the machine frame, a servo motor is mounted on the mounting frame, an output shaft of the servo motor is connected with the end part of the two-way lead screw through a coupler, the guide rod is vertically fixed to the side face of the machine frame, the sliding block is connected to the guide rod in a sliding mode, and a pressing plate is fixedly arranged on the sliding block. According to the punching machine for the outer package aluminum plastic film of the soft packing lithium battery, the aluminum-plastic film is taken out conveniently, the production efficiency is high, the molds are convenient to replace, the trouble of adjusting the inner sizes of the molds is avoided, errors caused by change of the inner sizes of the molds are avoided, the machining precision is improved, and movement is convenient.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a punching machine for an aluminum-plastic film for the outer packaging of a soft-pack lithium battery. Background technique [0002] Soft-pack lithium battery is a kind of lithium battery. Soft-pack lithium battery is just a liquid lithium-ion battery covered with a polymer shell. Inflated and cracked, the aluminum-plastic film needs to be punched and formed first in the processing of the soft-packed lithium battery, so that the battery core can be placed in the punched space; [0003] In the prior art: the patent of authorized publication number CN 109176723 B discloses a punching machine for aluminum-plastic film for the outer packaging of soft-packed lithium batteries, including a supporting base plate and a punching device, and the punching device is installed on the top of the supporting base plate; The stamping device includes a stamping frame, a suppor...
