Vacuumizing packaging mold and equipment, and battery cell manufacturing system

Abstract

The invention provides vacuumizing packaging equipment, and a battery cell manufacturing system. The vacuumizing packaging equipment comprises a mounting frame, a first die holder, a second die holder, an opening and closing driving assembly, a piercing mechanism, a heat sealing mechanism and a pressing mechanism, wherein the first die holder is arranged on the mounting frame, a first connecting hole is formed in the first die holder, the second die base covers the first die base, a containing cavity is defined between the second die base and the first die holder, the first connecting hole iscommunicated with the containing cavity, a containing table is arranged on an inner wall of the containing cavity in a protruding mode, the opening and closing driving assembly is arranged on the mounting frame, a power output end of the opening and closing driving assembly is connected with the second die holder, and the opening and closing driving assembly drives the second die holder to move relative to the first die holder, and the piercing mechanism is partially positioned in the accommodating cavity and is used for piercing the battery cell. Due to the fact that when the battery cell ispunctured, the pressing assembly presses the battery cell on the supporting plate assembly, exhaust efficiency in the battery cell is improved, and meanwhile, that gas in the battery cell is completely exhausted is guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery core manufacturing, in particular to a vacuum packaging mold and equipment, and a battery core manufacturing system. Background technique [0002] The cell processing process includes initial positioning, vacuum packaging, material cutting, edge ironing, edge trimming, bending, and edge ironing. Due to the poisonous and harmful substances contained in the battery cell, the lithium battery needs to be packaged after the liquid injection process is completed. The generated gas is extracted, and then the aluminum-plastic film is heated and pressurized in a vacuum environment to realize the vacuum packaging of the battery cell, so as to prevent the lithium battery from leaking when it is put on the market. [0003] Among them, the vacuum packaging process is a key process in the cell processing process, which determines whether the yield rate of cell manufacturing is up to standard. The working proc...

Problems solved by technology

[0004] However, when the traditional vacuum packaging mold punctures the cell, it can only allow the excess electrolyte in the cell and the gas generated in the cell to leak out naturally through the puncture hole, making the exhaust efficiency of the cell low , there is even a situation where the gas in the cell is heat-sealed before it is completely discharged
