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

Embodiment approach

[0041] The embodiment is specifically: the controller 23 controls the first servo motor 21 and the second servo motor 22 to work at the same time, so that the pressing belt 5 and the conveyer belt 7 rotate simultaneously, and the model size of the first servo motor 21 is the same as that of the second servo motor. The models and specifications of 22 are the same in size, ensuring that the power and rotating speed of the first servo motor 21 and the second servo motor 22 are the same, ensuring that the conveying speeds of the lower pressing belt 5 and the conveyor belt 7 are the same, and that the lower belt body of the lower pressing belt 5 moves The direction is the same as the movement direction of the upper belt body of the conveyor belt 7, which facilitates the transportation of the tabs, so that the tabs can move in the gap between the lower pressure belt 5 and the conveyor belt 7, and the tabs are placed on the conveyor belt through the feed port 10. On the belt 7, the co...

Abstract

The invention discloses an easy-to-operate tab flattening device for lithium-ion battery production, which includes a box body, a buffer frame is arranged on the upper part of the inner cavity of the box body, and a lower pressure frame is nested inside the buffer frame. The left and right ends of the inner cavity of the lower pressure frame are movably installed with first transmission rollers, and the surfaces of the two first transmission rollers are jointly sleeved with lower pressure belts, and the interior of the lower pressure belts is nested with The lower pressure roller is provided with a conveyor belt below the lower pressure belt, and the middle part of the conveyor belt is nested with support rollers at equal intervals, and the top of the box is nested with a sleeve through a bearing. The present invention squeezes and flattens the whole lug by pressing down the belt, so that the overall force of the lug is uniform, not easy to be damaged, and the probability of lifting the edge of the lug is reduced, and the overall flattening effect of the lug is good. By turning the handle , can adjust the distance between the pressing belt and the conveyor belt, thereby adjusting the overall pressure on the tab, effectively improving the flattening effect of the tab.

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 ...
