Automatic liquid injection type vacuum edge bonding machine

Abstract

The invention provides an automatic liquid injection type vacuum edge bonding machine, comprising a cylinder, a work chamber and a worktable arranged in the work chamber, wherein a transition bin is arranged on one end of the work chamber, a rotary operating panel is arranged on the other end of the work chamber, and a conveyor belt and a feeding platform are arranged on the table top of the worktable. The automatic liquid injection type vacuum edge bonding machine further comprises a feeding mechanical arm, a liquid injection mechanism, a first degassing standing box, a second degassing standing box, a third degassing standing box and a vacuumizing edge bonding mechanism, which are arranged right above the conveyor belt and are connected in sequence. The automatic liquid injection type vacuum edge bonding machine provided by the invention is completely sealed by a high-performance sealing pad, and an inlet dehumidifying device is further arranged, thus the low temperature and low humidity environment in the machine and the process requirements in the liquid injection process are ensured, the operation automation degree is high, the machine operation is simple, only one operator is needed in the whole production process to manually feed and discharge materials, and the intermediate processes are all automatically finished by machines, therefore, the production efficiency is improved and influence of the complicated intermediate processes to the product quality is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic liquid injection, degassing and sealing of polymer lithium-ion soft pack power batteries, in particular to an automatic liquid injection vacuum edge banding machine. Background technique [0002] Since entering the 21st century, countries have paid more and more attention to energy demand and the environment. Especially in the past two years, countries have basically reached a unified opinion on the impact of the greenhouse effect, which is to reduce CO 2 This has led to the rise of power batteries such as new energy electric vehicles, electric vehicles, energy storage mobile power supplies, and base station backup power supplies. New energy power batteries have the characteristics of inconsistency with conventional batteries. They are large in size and high in capacity. The difficulty of liquid injection in the battery production process is large, and the efficiency is low. At this stage, ther...

[0002] Since entering the 21st century, countries have paid more and more attention to energy demand and the environment. Especially in the past two years, countries have basically reached a unified opinion on the impact of the greenhouse effect, which is to reduce CO 2 This has led to the rise of power batteries such as new energy electric vehicles, electric vehicles, energy storage mobile power supplies, and base station backup power supplies. New energy power batteries have the characteristics of inconsistency with conventional batteries. They are large in size and high in capacity. Causes the difficulty of liquid injection in the battery production process, low efficiency, etc.

At this stage, there are two ways of battery injection: manual injection and automatic injection. Manual injection is generally suitable for small-capacity batteries such as Bluetooth, mobile phones, and MP3. Its characteristic is that it is only suitable for small-batch battery injection. , for the use of large-capacity batteries, resulting in high defect rate, low efficiency, and quality cannot be guaranteed

However, the existing automatic liquid filling machines do not work in a single line, and at least two workers are required to work, and the edge is sealed after one degassing, and the degassing is not complete, which is easy to cause battery failure, so that the amount of gas produced by the battery cell is different. , affecting battery performance
