Lithium battery current collecting plate shaping and bending device

Abstract

The invention provides a lithium battery current collecting plate shaping and bending device. The lithium battery current collecting plate shaping and bending device comprises battery slots for loading batteries and moving along with a conveying line, a machine frame is fixedly arranged on one side of the conveying line, and current collecting plates are welded on the end portions of the batteries. A pressing device for fixing the batteries is fixedly arranged at the position, directly above the batteries, on the machine frame, and an adjusting mechanism for adjusting the positions of the current collecting plates is fixedly arranged at the position, directly above the current collecting plates, on the machine frame. The machine frame is further provided with a bracing device for fixing the current collecting plates and a bending mechanism for bending the current collecting plates. The lithium battery current collecting plate shaping and bending device firstly performs the shaping operation on the current collecting plates before the bending operation, thereby ensuring that the current collecting plates do not shift during the bending operation, and further ensuring the subsequentprocess and improving the product qualification rate.

Description

technical field [0001] The invention relates to a bending device, more specifically, to a shaping and bending device for a lithium-ion cylindrical battery. Background technique [0002] In recent years, with the country's strong support for the new energy battery industry, the lithium-ion battery manufacturing industry has experienced unprecedented development. In this environment, the requirements for the qualification rate and production efficiency of lithium-ion batteries are becoming more and more stringent. Therefore, it is necessary to strengthen the control of each production process of battery production, improve the product qualification rate and production efficiency of each production process efficiency. [0003] The battery assembly process is an indispensable part of the lithium-ion battery production process. For example, after the current collector plate and the battery cell are welded, the current collector plate is bent. Due to the small welding point ar...

AI Technical Summary

Problems solved by technology

Due to the small welding point area between the current collector plate and the battery core, it is easy to cause the current collector plate to shift in the subsequent processes such as closing the cover; in addition, when the current collector plate is bent, due to the mechanical arm And when placing cylindrical batteries, sometimes it is easy to put them sideways, resulting in deflection of the bending position of the current collector plate; here, when the cylindrical battery is circulating on the line body, the slight vibration of the line body may also cause the current collector plate to deflect

Therefore, during the battery assembly process, it will cause the phenomenon that the cover cannot be closed, especially when it is running at high speed, resulting in a high scrap rate
