Soft-packaged battery transferring device

Abstract

The invention provides a soft-packaged battery transferring device applied to the technical field of soft-packaged battery production auxiliary equipment. The soft-packaged battery transferring device is characterized in that a device side plate I (2) is arranged at one side of a device base plate (1), a device side plate II (3) is arranged at the other side of the device base plate (1), multiple partition plates (4) are arranged on the device base plate (1), every two adjacent partition plates (4), the device side plate I (2) and the device side plate II (3) form a placing cavity (5), and a structure which can place one soft-packaged battery (6) is set in each placing cavity (5). The soft-packaged battery transferring device provided by the invention is simple in structure and can conveniently and reliably complete batch storage and transfer of soft-packaged batteries, aluminum plastic films on the surfaces of the batteries can not be damaged, side sealing edges of the batteries and lugs of the batteries can not be bent or damaged, the whole volume of the transferring device can be effectively reduced, batch transferring of the soft-packaged batteries can be realized, and the overall quality and performance of the soft-packaged batteries can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for production of flexible packaging batteries, and more specifically relates to a transfer device for flexible packaging batteries. Background technique [0002] Lithium-ion batteries are more and more widely used in power batteries because of their advantages such as high mass and volume specific energy, high voltage platform, and environmental protection. At present, there are three mainstream structures of lithium-ion batteries: cylindrical batteries, square hard-shell batteries and soft-pack batteries. Due to the advantages of good safety performance, light weight, small internal resistance, and flexible design, soft-packaged lithium-ion batteries are more and more widely used. Many models choose soft-packaged lithium-ion batteries as power batteries. Soft-packed batteries are heated and packaged by aluminum-plastic film, which has relatively low strength and is easy to wear and ...

AI Technical Summary

Problems solved by technology

Soft-packed batteries are heated and packaged by aluminum-plastic film, which has relatively low strength and is easy to wear and break during the transfer process, especially at the corner where the side seal of the battery meets the bottom edge of the battery. During the transfer process, the side seal of the battery has undergone repeated The bending of the aluminum-plastic film is easy to damage the aluminum layer, and small pinholes that are not easy to be observed will appear, resulting in slight liquid leakage and air intake, which will have a fatal impact on the battery as time goes on.

In the prior art soft-pack battery transfer device, one way of placing the battery is to lay it flat, and then transfer the battery through a hand-held air bag, causing the corner of one side of the air bag to bend multiple times during the turnover process, which is easy to damage. Another structure is that the battery is placed vertically with the air bag facing up. At this time, the other side sealing edge of the battery is directly supported on the bottom of the transfer device, which is prone to bending and damage to the battery during the turnover process.

In addition, the batteries are stacked tightly, and the battery tabs are easy to collide with each other and short circuit, thus causing safety hazards
