Folding mechanism and folding method of wrapping substrate for lithium battery

Abstract

The invention relates to a folding mechanism and folding method of a wrapping substrate for a lithium battery. The folding mechanism comprises a supporting plate and a first support, the first supportis arranged on the upper surface of the supporting plate, a first pressing rod is hinged to the first support, and the first pressing rod extends in the direction away from the first support; a through groove vertically penetrates through the upper end face of the first pressing rod downwards, inclined pressing blocks are arranged on the two side walls of the through groove respectively, first inclined faces are arranged on the upper portions of the inclined pressing blocks, and second inclined faces are arranged on the lower portions of the inclined pressing blocks. In the process of continuously clamping the wrapped substrate for the lithium battery through the clamping plate, the shaping block continuously applies pressure through the first pressing rod to extrude one part, protrudingout of the clamping plate, of the wrapped substrate for the lithium battery, and then the wrapped substrate for the lithium battery is finally clamped and synchronously extruded, folded and shaped bythe shaping block, so the purpose of clamping and folding the wrapping substrate for the lithium battery at the same time is achieved, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a folding mechanism and a folding method for wrapping substrates for lithium batteries. Background technique [0002] New energy batteries belong to green energy, and more and more attention has been paid to them, and they have developed rapidly in recent years. The commonly used battery type is a lithium battery, which has a large energy density and high safety, and is currently the most used type of battery. Lithium batteries often need to use a wrapping substrate to wrap the battery cell, and then the folding of the wrapping substrate for lithium batteries is relatively difficult, and the folding is often not uniform enough and the efficiency is low. If special equipment is used for production, the production cost will be greatly increased, and the convenience is poor, which is not cost-effective for small batch production. [0003] In order to solve the above prob...
