Eccentric cam type sealing assembly for lithium battery

Abstract

The invention discloses an eccentric cam type sealing assembly for a lithium battery. The sealing assembly includes a synchronous belt, a driving wheel, a driven wheel, a box body, a box cover, a bearing seat, and a power shaft. The sealing assembly also includes an eccentric wheel. , counterweight cover, eccentric shaft, push rod guide sleeve, push rod, the eccentric shaft is connected to the top of the box and runs through the whole box, the eccentric wheel is sleeved on the eccentric shaft and placed in the center of the box cover, and the eccentric shaft The side sleeve has a driven wheel, and the other side of the eccentric shaft is also covered with a counterweight cover. One side of the push rod guide sleeve is connected to the box cover to guide the movement direction of the push rod. The push rod is sleeved in the push rod guide sleeve, and the driven wheel drives the eccentric shaft. The rotation drives the eccentric wheel to rotate, and the rotation of the eccentric wheel drives the push rod to reciprocate up and down. The invention realizes the electric reciprocating sealing of the lithium battery, reduces the high temperature, high heat and noise generated when the sealing assembly starts, and improves the sealing efficiency.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to an eccentric cam type sealing assembly for lithium batteries. Background technique [0002] Due to their small size, lithium batteries have been widely used in various microelectronic products, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm; they are generally used as backup power for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc. [0003] Lithium batteries are also divided into two categories: chemical batteries and physical batteries. Chemical batteries are the most widely used. They are composed of anode (positive electrode), cathode (negative electrode) and electric contact liquid. Its appearance is made of stainless steel and serves a...

Problems solved by technology

[0004] Lithium batteries generally require secondary sealing after assembly. At present, the sealing assemblies used for lithium battery sealing mainly include hydraulic and manual. The hydraulic sealing assembly is prone to oil leakage, which causes damage to the battery. Manual sealing generally The sealing efficiency is too low and the sealing strength is not enough, the quality of the packaged lithium battery is unqualified, and the existing sealing assembly takes up a lot of space, and the drive generates a lot of noise during use. In order to efficiently process the assembled lithium battery Sealing, and to ensure the quality of lithium batteries, there is an urgent need for a sealing assembly to solve this phenomenon
