A damage detection mechanism for the bottom corner of the soft-packed core of lithium battery

Abstract

The invention discloses a lithium battery flexibly packaged core base angle position damage detection mechanism. The lithium battery flexibly packaged core base angle position damage detection mechanism comprises a detection table and a detection camera; the detection camera is arranged above the detection table; horizontal adjustment columns are arranged at the bottom of the detection table; a table surface base is mounted below the horizontal adjustment columns; the bottom of the table surface base is connected with a base supporting leg; the detection table comprises a table surface, a first fixed plate, a second fixed plate, the horizontal adjustment columns, the table surface base, and the base supporting leg; the first fixed plate and the second fixed plate are arranged on the two sides of the upper surface of the table surface; the horizontal adjustment columns are arranged on the lower surface of the table surface; each horizontal adjustment column comprises a table surface supporting column and a base frame supporting column; the table surface supporting columns are arranged on the lower surface of the table surface; the base frame supporting column matched with the tablesurface supporting column is mounted below the corresponding table surface supporting column; and the table surface base is arranged below the base frame supporting columns. The lithium battery flexibly packaged core base angle position damage detection mechanism has the characteristics of convenience in fixation and detachment, adjustability of multiple angles, high compatibility and large detection range.

Description

technical field [0001] The invention relates to a damage detection mechanism for the bottom corner of a soft-packed lithium battery core, in particular to a damage detection mechanism for the bottom corner of a soft-packed lithium battery core with convenient fixing and disassembly, multi-angle adjustment, strong compatibility, and a large detection range. Background technique [0002] The proportion of aluminum-conductive plastic film soft-pack batteries in power batteries is getting higher and higher. The packaging of soft-pack batteries is usually completed by hot-pressing the opening of the aluminum-plastic film packaging bag with a packaging machine. [0003] On the pressing surface of the packaging device, there is an air guide groove that runs through the pressing part. During the packaging process, the gas generated by the aluminum-plastic film or electrolyte can be discharged, reducing the air pressure on the aluminum-plastic film and avoiding the generation of air h...

Problems solved by technology

However, in the prior art, the damage detection of soft-packed lithium batteries is mainly completed by the visual inspection of inspectors. For most lithium batteries with serious damage, inspectors can make judgments more conveniently and accurately. However, for some slightly damaged lithium batteries Lithium batteries, because the damaged holes or gaps are small, it is difficult to make accurate judgments only by naked eye observation, which is prone to misjudgments and missed judgments, which affects the quality of lithium battery products and is not conducive to improving detection efficiency.
