Embodiment approach 1

[0012] See figure 1 As shown, put the sealing ring of the alkaline button battery into the centrifugal vibrating plate that starts, and the sealing ring of the alkaline battery will pass through the tunnel with the sealing glue with a glue content of 10-20% one by one in the upward direction of the mouth. The magnetic strip with a width of 2-6mm will suck up the negative electrode cover installed in the sieve cover plate, and forcefully press the negative electrode cover into the sealing ring that has passed through the glue tunnel, so that the negative electrode cover and the sealing ring cooperate well, and then pass through 50-60 Bake for 30-180 minutes at a temperature of ℃, after cooling, pack it into a bag and seal it for storage, and then put it into assembly production.

Embodiment approach 2

[0014] Push the sealing rings one by one into the tunnel filled with 10-20% sealing glue by hand in the upward direction of the mouth, use a magnetic strip with a width of 2-6mm to suck up the negative electrode cover, and press the negative electrode cover firmly Insert the sealing ring to make the negative electrode cover and the sealing ring that have passed through the glue tunnel fit well, and then bake at a temperature of 50-60°C for 30-180 minutes. After cooling, pack it into a bag and seal it for storage, and then put it into assembly production.

Abstract

The invention relates to a casing method of a seal ring of an alkaline button cell, and the method can solve the problem of cell leakage. In the method, the seal ring is caused to sequentially pass through a tunnel with 10-15% of sealing glue along the upward direction of the mouth part of the seal ring, then 5-15 cathode covers are attracted by a magnetic strip with the width of 2-6mm, and the cathode covers are pressed into the seal ring which passes through the glue tunnel to form a combination body, and the combination unit is put into an environment with the temperature of 50-60 DEG C and baked for 30-180 minutes, and then packaged for use after being cooled. Compared with the conventional seal ring casing method, the method has operability, the key point of the method is that the glue is in a fluid state while casing the seal ring, the cathode covers and the seal rings are bonded when the glue is in the fluid state, then dried at high temperature or blown dry by strong wind, thus achieving perfect sealing effect.

Description

Technical field: [0001] The invention relates to the technical field of batteries, in particular to a sealing ring cover method for an alkaline button battery that can solve the problem of battery leakage. Background technique: [0002] As we all know, for electrical appliances and customers using alkaline batteries, battery leakage is the main reason for affecting battery performance and abnormal electrical appliances. Especially the alkaline button battery, due to its special structure, the alkaline button battery will leak after being stored for a certain period of time. However, due to the difference in production process, the storage time and leakage degree of the battery will have certain differences. [0003] Therefore, solving the leakage problem of alkaline button cells and how to prolong the time during which they do not leak have always been the key and difficult issues of alkaline button cell manufacturers and the battery industry. The method of sealing the neg...
