Baking vacuum stewing machine for producing Li-polymer battery

Abstract

The invention relates to a baking vacuum stewing machine for producing Li-polymer battery, which comprises a first equipment cabinet and a second equipment cabinet. The first equipment cabinet is fixed with the second equipment cabinet. A battery conveying mechanism is installed inside the second equipment cabinet. Baking vacuum chambers are symmetrically arranged on the two sides of the batter conveying mechanism. A battery shifting mechanism is arranged at the upper portion of the battery conveying mechanism. The battery conveying mechanism, the baking vacuum chambers and the battery shifting mechanism are respectively fixed with the second equipment cabinet. The baking vacuum stewing machine can replace a vacuum dying room, and has the advantages that the labor force and material resource are saved, the maintenance cost is low, the occupied room is small, the drying time is short, the cost is low, the production efficiency is high and the economic benefit is good. The baking vacuum stewing machine can form vacuum state -99.9 kpa inside the machine, and enter inside the machine through the protective air, then heat to 80 DEG C. The moisture inside the Li-polymer battery shell placed inside the machine can be completely volatilized within 30 minutes under the above status, which is 48 times than the dying speed in the vacuum dying room, and the production efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a baking vacuum static machine for producing pouch batteries. Background technique [0002] Soft pack battery is another name for polymer battery. Compared with lithium-ion 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 pouch battery case needs to be dried before the electrolyte is injected. Because the pouch battery case 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 case of pouch battery is easy to deteriorate when it is above 100°C, which leads to an increase in the rate of defective products and reduces economic benefits. [0004] Therefore, in the prior art, the pouch battery casing is drie...
