Battery core shaping mechanism and fully-automatic battery core liquid-extracting, packaging and shaping packing machine

Abstract

The invention discloses a fully-automatic battery core liquid-extracting, packaging and shaping packing machine used for extracting liquid from a flexibly packed lithium battery and packaging and shaping the flexibly packed lithium battery, and a battery core shaping mechanism thereof. The key point of the invention lies in the design of the battery core shaping mechanism. The mechanism comprisesa turntable device, wherein an edge-cutting device, a preheating device, an edge-folding device and an edge-ironing device are sequentially arranged along the outer edge of the turntable device. Due to the design, the structure of the battery core shaping mechanism is compact. More importantly, the preheating device is arranged in front of a folded edge device, so an aluminum-plastic membrane corner can be prevented from being broken when the edge of a flexibly packed battery core is folded; and the quality and the forming rate of the product are guaranteed. A correcting device with a pressure sensor is also arranged beside the edge-cutting device and the edge-folding device, so the consistency of forming the flexibly packed lithium battery is guaranteed and the battery core is not damaged by correcting the position of the battery core before the edge of the battery core is cut and folded.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a fully automatic cell pumping, sealing, forming packaging machine and cell shaping mechanism for forming soft-packed lithium batteries. Background technique [0002] At present, the outer packaging of lithium batteries is generally divided into metal shells and non-metallic shells. In comparison, batteries prepared with non-metallic shells (ie, soft-pack lithium batteries) can significantly reduce the cost of lithium batteries and increase the energy density of batteries. and power density; in the past, soft-pack lithium battery manufacturers usually used manual operations in the molding process after packaging the soft-pack batteries, using knife dies and punching machines to trim the edges of the soft packages, and then using fixtures to manually pre-set the edges of the soft packages. Bend, and then manually iron the folded edge on the heating plate to form the f...

AI Technical Summary

Problems solved by technology

This equipment can automatically complete the sealing and forming of soft-pack lithium batteries. Compared with manual operation, it has high efficiency, high battery stability, and good molding consistency; The production quality and efficiency of the battery put forward higher requirements. When the above-mentioned equipment is folded, the aluminum-plastic film at the soft package seal will harden due to the previous heat sealing, and the folded corners are prone to damage during the fold. low yield
