Problems solved by technology

[0002] About the new energy lithium battery cell tab cutting device refers to a new application made by using the existing cutting method, the traditional new energy lithium battery cell tab cutting device, the cutting efficiency is not high, and After cutting, the sharp corners of the tabs are quite sharp, which directly affects the smooth progress of follow-up work, affecting safety and efficiency
[0003] Therefore, the removal of the R angle by cutting the tabs of the cell plays a relatively important role, especially to prevent the bending R angle from exceeding the cell body, which will cause the aluminum-plastic film to be pierced in the follow-up work, resulting in safety accidents and battery scrapping

Abstract

The invention discloses a cutting apparatus for a tab of a battery core. The cutting apparatus comprises a frame, wherein a workbench is arranged on the frame and is provided with a convex-arc downward cutting knife; the frame is provided with a cylinder which is located above the convex-arc downward cutting knife, and the output terminal of the cylinder moves downwards and is connected with a concave-arc upward cutting knife which moves downwards with the cylinder and is cooperated with the convex-arc downward cutting knife for cutting of the tab of the battery core; and a positioning stop dog for limiting the cutting length of the tab of the battery core is arranged behind convex-arc downward cutting knife. According to the invention, the concave-arc upward cutting knife and the convex-arc downward cutting knife are utilized for cutting the tab, so a bent R angle is better prevented from extending out from the body of the battery core to puncture an aluminum-plastic diagram, and thus, accidents and battery scraping caused by the puncture of the aluminum-plastic diagram are prevented.

Description

[technical field] [0001] The invention relates to a battery tab cutting device. [Background technique] [0002] About the new energy lithium battery cell tab cutting device refers to a new application made by using the existing cutting method, the traditional new energy lithium battery cell tab cutting device, the cutting efficiency is not high, and After cutting, the sharp corners of the lugs are quite sharp, which directly affects the smooth progress of follow-up work and affects safety and efficiency. [0003] Therefore, the removal of the R angle by cutting the tabs of the cell plays a relatively important role, especially to prevent the bending R angle from exceeding the cell body, which will cause the aluminum-plastic film to be punctured in the follow-up work, resulting in safety accidents and battery scrapping. [Content of the invention] [0004] The present invention overcomes the deficiencies of the above-mentioned technologies, and provides a battery tab cuttin...
