Battery corner seal positioning mechanism based on packaging equipment

Abstract

A battery corner sealing positioning mechanism based on packaging equipment comprises a rack, the rack comprises an upper plate, a lower plate and two side plates installed on the two sides of the upper plate and the two sides of the lower plate, and the two sides of the upper plate and the two sides of the lower plate are connected with the upper ends and the lower ends of the side plates respectively; and the battery corner sealing positioning mechanism further comprises an upper corner sealing mechanism and a lower corner sealing mechanism. The upper corner sealing mechanism is mounted on the upper plate; the lower corner sealing mechanism is mounted below the lower plate; and the upper corner sealing mechanism and the lower corner sealing mechanism are a pair of mutually symmetrical mechanisms, wherein the upper corner sealing mechanism comprises an air cylinder, a piston mounting plate, a corner sealing heating body, an corner sealing mounting plate; a corner sealing head, an adjusting screw and a sealing head adjusting seat, the air cylinder is downwards installed on the upper plate, a through hole is formed in the upper plate and used for the piston end of the air cylinder to penetrate through, the piston end of the air cylinder penetrates through the lower end of the upper plate through the through hole and is connected with the piston mounting plate which tends to be horizontally fixed, the corner sealing mounting plate is fixed to the lower end of the piston installation plate, and the corner sealing heating body is fixed below the angle seal installation plate.

Description

technical field [0001] The invention relates to the field of mechanical mechanisms, in particular to a battery corner seal positioning mechanism based on packaging equipment. Background technique [0002] Flexible packaging lithium-ion batteries generally use aluminum-plastic film as the packaging material. The packaging material has a three-layer structure: a polypropylene layer, a nylon layer, and an aluminum layer between the polypropylene layer and the nylon layer. The aluminum layer can provide certain molding capabilities. and mechanical strength, and can block the entry of water vapor. Therefore, in order to prevent moisture from entering the battery interior, it is crucial to maintain the integrity and sealing of the aluminum layer in the packaging aluminum foil. Therefore, in the field of soft-pack lithium battery production, it is necessary to perform top-side sealing and corner sealing on the aluminum-plastic film. The existing corner sealing mechanism has the de...

Problems solved by technology

Therefore, in the field of soft-pack lithium battery production, it is necessary to perform top-side sealing and corner sealing on the aluminum-plastic film. The existing corner sealing mechanism has the defect of a single structure, and the adjustment after the mechanism is positioned is relatively limited, resulting in , the mechanism can only add lithium-ion batteries of limited types and sizes, and lithium-ion batteries of various sizes need to be processed by different mechanisms, which will cause troublesome processing steps and increase the cost of the mechanism; in order to solve For this defect, a kind of automatic packaging device for corner positions of soft-packed lithium batteries has appeared in the prior art as described in the announcement number: "CN 204088492 U", which enables the corner sealing mechanism to adapt to more Various types of lithium battery corner seals, but there are still certain limitations, and the problem cannot be solved from the corner seal mechanism body
