Coating device of battery sealing agent

Abstract

The invention discloses a coating device of a battery sealing agent, which is characterized by comprising a coating mechanism, an agent-passing tube, an agent cylinder and a heating mechanism, wherein the heating mechanism is arranged at the bottom of the agent cylinder with the sealing agent arranged therein; the agent cylinder is communicated with a compressed air, the sealing agent in the agent cylinder is delivered to the coating mechanism through the agent-passing tube under the action of the compressed air; and a switch device used for automatically adjusting the flow of the sealing agent according to the pressure variation of the compressed air is arranged in the coating mechanism. The device has the advantages that the heating mechanism is arranged at the bottom of the agent cylinder and is used for heating the sealing agent in the agent cylinder and for maintaining the temperature of the sealing agent; the sealing agent with a viscosity number below 20,000 can be smoothly delivered through pressing; the flow of the sealing agent in the coating mechanism can be automatically adjusted as long as the pressure of the compressed air is better controlled, without the problems of glue interruption, noncontinuous glue spreading and the like, so that the continuous glue spreading and good controllability are achieved; and accordingly, the sealing of the battery is effectively ensured and the production efficiency is high.

Description

technical field [0001] The invention relates to batteries, in particular to a battery sealing agent coating device. Background technique [0002] With the continuous research and development of various new electrical products, the usage of the current mainstream alkaline zinc-manganese batteries is increasing at an annual growth rate of 33.92%. As the world's largest battery producer and exporter, the annual output of alkaline batteries in my country reached about 12 billion in 2012. At the same time, higher requirements are placed on battery performance and manufacturing technology. [0003] Sealing agent coating is an important process in battery manufacturing technology, which is to evenly coat the sealing agent on the surface of the battery steel case. At present, in the industry, most of the battery sealing agent coating equipment is controlled by a piston-type mechanical valve, which is intermittent spraying, and the stroke of the piston is prone to fluctuations, maki...

AI Technical Summary

Problems solved by technology

At present, in the industry, most of the battery sealing agent coating equipment is controlled by a piston-type mechanical valve, which is intermittent spraying, and the stroke of the piston is prone to fluctuations, making it difficult to control the coating amount. In addition, if the sealing of the piston is not good, during the coating process Air is easy to enter the mechanical valve, so the existing battery sealing agent coating equipment has poor controllability to the amount of sealing agent coating, prone to problems such as glue breaking and glue discontinuity, and low production efficiency
