Lithium battery connecting sheet welding device

Abstract

The embodiments of the present application belong to the technical field of lithium battery production, and relate to a welding device for connecting tabs of lithium batteries. The technical solution provided by the application includes a frame, a feeding mechanism, a cutting mechanism, a welding mechanism and a conveying mechanism; the feeding mechanism, the cutting mechanism, the welding mechanism and the conveying mechanism are arranged on the frame; At the position where the connecting piece is conveyed to the cutting mechanism and the conveying mechanism; the cutting mechanism is arranged between the feeding mechanism and the welding mechanism for cutting the connecting piece conveyed by the feeding mechanism; the The conveying mechanism is arranged on the welding station of the welding mechanism, and is used to transport the cut connecting piece to the lithium battery module, so that the welding mechanism can weld the connecting piece on the lithium battery module, which can automatically Feeding, automatic cutting, and automatic welding, so as to ensure that the connecting piece can be welded stably during the production of lithium battery modules, which reduces the defect rate, saves labor costs, and improves production efficiency.

Description

technical field [0001] This application relates to lithium battery production technology, and more specifically, to a lithium battery connecting piece welding 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. With the development of science and technology, lithium batteries have become the mainstream now. [0003] In the production of lithium battery modules, laser welding is used to complete the connection of the module batteries themselves. The traditional connection method between the module batteries is to sta...
