Sheet type tab processing device

Abstract

The invention discloses a sheet type tab processing device. The processing device comprises a machine frame, a lifting mechanism, a transferring mechanism, a restoration material cutting mechanism and a feeding mechanism, wherein the lifting mechanism, the transferring mechanism, the restoration material cutting mechanism and the feeding mechanism are installed on the machine frame. The restoration material cutting mechanism comprises a restoration unit, a material cutting unit and a driving unit, wherein the restoration unit is used for conducting restoration processing on a plate of tabs, the material cutting unit is used for segmenting a sheet type tab from the plate of tabs in a third set position, and the driving unit is used for driving the material cutting unit to move longitudinally. The material cutting unit comprises a hook, a cutting knife and a pressing block, wherein the hook is capable of downwards extending into a clearance between two sheet type tabs at the most front end of the plate of tabs so as to hook the tabs to move forwards, so that the sheet type tabs at the most front end of the plate of tabs are located at the third set position; the cutting knife can move downwards for cutting apart the joint of the two sheet type tabs at the most front end of the plate of tabs; the pressing block is capable of tightly pressing the plate of tabs downwards when the cutting knife does cutting action downwards. The sheet type tab processing device is compact in structure, the sheet type tabs are high in segmentation stability and precision, and the device can be well suitable for segmentation processing of plate type pole pieces.

Description

technical field [0001] The invention relates to a lithium battery processing device, in particular to a processing device for cutting plated tabs. Background technique [0002] on the one hand, Figure 1A , 1B and Figure 1C It shows a type of pole piece. When storing this type of pole piece, a plurality of spacers 92 are used to stack two adjacent plate tabs 91 at intervals to form a stack of tabs and spacers. In combination, each plate tab 91 includes a plurality of sheet tabs 911 that are horizontally connected and arranged with gaps 912 therebetween. Each tab tab 911 includes a connecting portion 9111 , a first metal strip 9112 located on one side of the connecting portion 9111 , and a second metal strip 9113 located on the other side of the connecting portion 9111 . During the processing of the lithium battery, the single tab tab 911 is cut off for processing such as welding with the battery cell. [0003] On the other hand, an existing pole piece cutting machine ha...
