Tab flattening device with simple and convenient operation for lithium ion battery production

Abstract

The invention discloses a tab flattening device with simple and convenient operation for lithium ion battery production, which comprises a box body, wherein a buffer frame is arranged on the upper portion of an inner cavity of the box body, a pressing frame is embedded in the buffer frame, first transmission rollers are movably installed at the left end and the right end of the inner cavity of the pressing frame correspondingly, the surfaces of the two first transmission rollers are jointly sleeved with a lower pressing belt, lower pressing rollers are embedded in the lower pressing belt at equal intervals, a conveying belt is arranged below the lower pressing belt, supporting rollers are embedded in the middle of the conveying belt at equal intervals, and a sleeve is embedded in the top of the box body through a bearing. According to the invention, the lower pressing belt is used for extruding and flattening the whole tab so as to enable the whole tab to be stressed uniformly and not easy to damage, the probability that the edges of the tab tilt is reduced, the whole flattening effect on the tab is good, and the distance between the lower pressing belt and the conveying belt can be adjusted by rotating the handle, so that the pressure on the whole tab is adjusted, and the tab flattening effect is effectively improved.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to an easy-to-operate tab flattening device for lithium ion battery production. Background technique [0002] Lithium-ion battery is a rechargeable battery first proposed by Exxon Mobil chemist Stanley Whittingham in the 1970s. Lithium-ion batteries are commonly used in portable electronics and electric vehicles, and are increasingly popular in military and aerospace applications. The battery needs to use tabs. The tabs are metal conductors that lead the positive and negative poles out of the battery. The ears of the positive and negative poles of the battery are the contact points when charging and discharging. It is a connection inside the battery. The ears are divided into three materials. The positive electrode of the battery is made of aluminum, the negative electrode is made of nickel, and the negative electrode is also made of nickel-plated copper. They are all composed ...

Problems solved by technology

[0003] At present, the existing tab flattening device of the lithium-ion battery is to flatten the tab by rolling the rolling roller on the tab, but when the rolling roller rolls and flattens the middle part of the tab, it is easy to make the two ends of the tab The edge is easy to warp, and the local force on the tab is easy to damage, which reduces the flattening effect of the tab
