New energy battery production line tab bending and rolling device

Abstract

The invention discloses a new energy battery production line tab bending and rolling device which comprises a base and a bending structure, wherein a bending mechanism is arranged at the top end of the base, and the bending mechanism judges the position of a battery tab of a storage battery through an observation mechanism at the front end. The position of a bending insertion plate at the front end is moved through a transverse steering engine and a vertical steering engine, so that the bending insertion plate is aligned with the battery tab of the storage battery, meanwhile, a pneumatic rod is started to push the bending insertion plate at the front end, the bending insertion plate conducts punching and bending on the battery tab at the front end, then the surface of the battery tab is pressed and covered with a rolling and flattening shaft, the transverse steering engine moves, so that the rolling and flattening shaft presses and bends the battery tab, and when metal fatigue is generated after the bending insertion plate is used for a long time, a fixing bolt in a fixing groove in one side of the bending insertion plate is detached, and compared with a traditional battery production line tab bending, rolling and flattening device, the disassembly of the front end of the bending insertion plate effectively improves the replacement and maintenance efficiency of equipment use.

Description

technical field [0001] The invention belongs to the technical field related to battery production devices, and in particular relates to a tab bending and rolling device for a new energy battery production line. Background technique [0002] Tabs are a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, bluetooth batteries, notebook batteries, etc. we use in our life need to use tabs. The battery is divided into positive and negative poles. The tab is a metal conductor that leads the positive and negative poles out of the battery. It is said that the ears of the positive and negative poles of the battery are the contact points when charging and discharging. The battery tabs include the tab metal strip. One end of the tab metal strip is connected to the pole piece in the packaging bag made of aluminum-plastic packaging film. One end extends to the outside of the packaging bag mouth, and a section of tab metal strip at the packaging bag ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new energy battery production line tab bending and rolling device to solve the problem that the existing battery production line tab bending and rolling device usually uses mechanical equipment during the use process. The stamping process of one-time forming of the lugs, which is easy to cause the bending and fracture of the tabs, will affect the processing and use of the battery. The new tab processing device usually uses metal plates to pre-bend, and then uses rollers to bend during long-term use. Bending plates are prone to metal fatigue, which causes the equipment to be replaced, which makes the maintenance cost of the equipment too high, and at the same time reduces the operating efficiency of the equipment.
