Abstract

The invention discloses a lithium battery pole piece bending device which comprises a base plate, a pole piece sleeve column and a bending column. Struts are welded to the top and the bottom of one side of the base plate, the top ends of the two struts are rotationally connected with a conveying belt through shaft sleeves, the pole piece sleeve column is welded to the conveying belt, a hydraulic expansion link is welded to the center of one side of the base plate, a separating plate is welded to the top end of the hydraulic expansion link, the bottom end of the separating plate is elasticallyconnected with a limiting plate through a spring, a limiting groove is formed inside the limiting plate, and the top end of the limiting plate is rotationally connected with a ball screw through a rotating shaft. According to the lithium battery pole piece bending device, the pole piece sleeve column is welded to the conveying belt, a pole piece can be limited by the limiting plate, the pole piececan be bent without manual fixation, the fixing time is saved, and the bending working efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of lithium battery equipment, in particular to a lithium battery pole piece bending device. Background technique

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metall...
