An improved battery glue injection device

Abstract

The invention provides an improved battery glue injection device, which belongs to the technical field of battery production. The improved battery glue injection device includes a bearing platform, a material tank for storing colloid, and several glue injection components. The glue assembly includes the glue injection pipe fixed on the bearing platform and the power parts corresponding to the glue injection pipe. In the middle of the glue injection pipe, there is a vertically set glue injection channel and a glue injection outlet connected with the glue injection channel. The material tank and each The glue injection pipes are respectively connected and can transport the glue to the corresponding glue injection channels. The end of the power part is connected to the glue injection needle rod coaxially arranged with the glue injection channel through the floating joint. The power part is movably connected on the bearing platform and can be driven The glue injection needle rod extends into the glue injection channel and discharges the colloid in the glue injection channel from the glue injection outlet. The improved battery glue injection device has the advantages of reasonable structure, economy and applicability, and good glue injection effect.

Description

technical field [0001] The invention belongs to the technical field of battery production and relates to an improved battery glue injection device. Background technique [0002] With the advancement of battery technology, the production technology of alkaline batteries is becoming more and more mature, and the market demand is large. In some battery production lines, due to the relatively large volume of some batteries, it is relatively difficult to curl the head of the sealing end of the rolling paper inside. It is difficult to ensure that the sealing end of each battery steel case can be ironed firmly. If there is a gap in the seal of the diaphragm paper, the electrolyte will seep out after the electrolyte is injected, which will cause the battery to climb alkali, gas, and even cause the battery to explode, which is extremely dangerous. Therefore, a glue injection process needs to be added after the diaphragm paper is inserted. [0003] The glue injection process is the...

AI Technical Summary

Problems solved by technology

The structure of the battery glue injection device in the prior art is realized by a high temperature resistant glue injection valve body, which is expensive and has multiple sealing rings inside to ensure its tightness

However, due to the high temperature and the special viscosity of the colloid, the sealing ring is easily damaged and inconvenient to maintain

And the weight cannot be adjusted. The current weight is adjusted by the length of the glue injection time, which is extremely unstable.

Furthermore, since the current injection of colloid is not achieved by air pressure, the injected colloid will accumulate in the middle of the bottom of the battery steel case like water droplets, and cannot be spread evenly, resulting in unsatisfactory injection effect
