Vacuum baking and filling sealing machine for soft package battery

Abstract

The invention relates to a vacuum baking and filling sealing machine for a soft package battery. The vacuum baking and filling sealing machine for the soft package battery comprises a vacuum baking part, a vacuum filling part and a sealing cover, wherein the vacuum baking part and the vacuum filling part are arranged in the sealing cover; the vacuum baking part comprises a first rack, a feeding mechanism, a distributing mechanism, a first feeding mechanism, a second feeding mechanism, a first oven group, a second oven group, a first battery core unloading and loading mechanism, a second battery core unloading and loading mechanism, a material shifting mechanism and a first weighing mechanism; and the vacuum filling part comprises a second rack, a first reclaiming mechanism, a material pushing mechanism, a material receiving mechanism, a vacuum filling mechanism, a vacuum standing mechanism, a first vacuum sealing mechanism, a second vacuum sealing mechanism, a battery core clamp circulating mechanism, a second reclaiming mechanism, a second weighing mechanism, a discharge mechanism and a battery box supply mechanism. The vacuum baking and filling sealing machine for the soft package battery is capable of carrying out operations of drying, filling, sealing and the like on a battery core in a vacuum sealing condition, so that manpower is saved; the production efficiency is high; the properties of the battery are kept; the maintenance cost is low; and the defective rate is low.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a vacuum baking liquid injection sealing machine for soft pack batteries. Background technique [0002] Soft pack battery is another name for lithium-ion battery. Compared with lead-acid batteries, it has many advantages such as small size, light weight, high specific energy, high safety, and flexible design. [0003] In the production process of the pouch battery, the main body of the pouch battery needs to be dried before the electrolyte is injected. Because the separator in the main body of the pouch battery is not resistant to high temperature, the drying temperature should not be too high. As we all know, under normal pressure, the evaporation temperature of water is above 100°C, and the separator in the main body of the pouch battery is easy to deteriorate when it is above 90°C, the performance of the battery will decrease, and the capacity will become smaller,...

AI Technical Summary

Problems solved by technology

The drying method for the main body of the pouch battery has the following defects: the cost of establishing a vacuum drying room is high, the operating cost is high, the space occupied is large, the drying time is long, the cost is high, the production efficiency is low, and the economic benefit is poor

A small amount of moisture in the environment will be injected into the battery cell along with the electrolyte, and excess moisture will reduce the performance of the battery, increase the rate of defective products, increase production costs, and reduce economic benefits. There is a need for improvement
