Problems solved by technology

The positioning of the sealing position by traditional sealing equipment is not accurate enough. When the steel ball is driven in, it is easy to cause the deformation of the battery cover plane, and the steel ball is prone to rebound when it enters the battery cover; at the same time, the current equipment requires the cooperation of multiple stations for the operation of sealing the steel ball. Due to the processing accuracy of multiple stations, the pass rate of steel balls is easy to be low. At the same time, the production cycle of multi-station production is low, which is not conducive to the improvement of overall product production efficiency.

Abstract

The present invention relates to a steel ball sealing mechanism used for a lithium battery liquid-injection mouth. The mechanism comprises a straight line module. A sliding table of the straight linemodule is provided with a straight line guiding rail and a positioning cylinder. The straight line guiding rail is flexibly connected with a fixing rack, and a piston rod of the positioning cylinder is connected with fixing rack. The surface of the fixing rack is fixed with a pushing rod cylinder, the bottom of the fixing rack is fixed with a positioning sealing plate, one end of the positioning sealing plate is provided with a sliding slot, and the other end of the positioning sealing plate is fixed with a shifting cylinder. The bottom of the sliding slot is provided with a sealing pushing mouth, a steel ball shifting block is arranged in the sliding slot, and the surface of the steel ball shifting block is provided with a steel ball pushing rod through hole. The mechanism integrates thefunction of conveying steel ball(s), obtaining the steel ball(s), flexible positioning and sealing and static fixing punching position. The whole mechanism has the advantages of compactness, small occupied space, flexible and convenient operation and precise positioning of the sealing position. The deformation of the battery cover surface is effectively avoided when the steel ball is punched, andthus the steel ball can be efficiently punched in the battery cover plate without rebounding.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a mechanism for sealing the liquid injection port of the lithium battery with steel balls after liquid injection. Background technique [0002] After the lithium battery is injected, it is particularly important to seal the liquid injection port on the battery cover. At present, the usual sealing method is to plug steel balls into the liquid injection port. The positioning of the sealing position by traditional sealing equipment is not accurate enough. When the steel ball is driven in, it is easy to cause the deformation of the battery cover plane, and the steel ball is prone to rebound when it enters the battery cover; at the same time, the current equipment requires the cooperation of multiple stations for the operation of sealing the steel ball. However, due to the processing accuracy of multiple stations, it is easy to cause a low pass rate of steel balls. At the sam...
