Abstract

The invention discloses a punching device of a high-capacity dynamical lithium-ion battery lug, which comprises a supporting part, and a driving part and a clamping part which are fixedly connected with the supporting part and an executing part connected with the driving part, wherein the supporting part is used for supporting the whole device; the clamping part is used for clamping the battery lug; the driving part is used for directly providing mechanical power for the executing part and driving the executing part to make linear movement, wherein a punching knife is embedded in the executing part; a through hole matched with the punching knife is respectively arranged in the corresponding clamping part and the supporting part; and the position of the through hole corresponds to that of the punching hole. The punching hole has the characteristics of reasonable structure, convenient and simple use, safe operation and small occupation area and the advantages of easy pore forming and high punching efficiency and also can reduce the potential safety hazard of the battery.

Description

technical field [0001] The invention belongs to the field of lithium-ion batteries, in particular to a large-capacity power lithium-ion battery lug punching device. Background technique [0002] As a new generation of secondary battery system, lithium-ion battery has the remarkable characteristics of high specific energy and high specific power. It is an ideal choice for high-tech applications such as mobile electronic equipment, electric vehicles, and national defense industry. With the application of capacity-type and power-type power lithium-ion batteries, the way of connecting the pole tabs of the square shell to the positive and negative current collectors of the battery can no longer meet the needs of high-current discharge of lithium-ion batteries. Large-capacity lithium-ion batteries are usually welded by ultrasonic welding in the process of manufacture and use, but due to the easy welding, de-soldering or over-soldering during the ultrasonic welding process, it is e...
