Patent number: 11848436Abstract: Disclosed is method and device for forming an electrode plate. The method includes: performing tab cutting on a substrate so that the substrate forms a body portion, an edge portion connecting to the body portion, and a plurality of tabs that connect to the body portion but are separated from the edge portion; and performing edge portion cutting on the substrate to separate the edge portion from the body portion. The electrode plate is formed in two steps. First, the tab and the edge portion are separated, so that in the process of cutting, impact of vibration of the edge portion on the tab is small, greatly reducing the risk of deformation of the tab caused by vibration of the edge portion and damage to the tab caused by being pulled by the edge portion. Second, edge portion cutting separates the edge portion from the body portion.Type: GrantFiled: March 15, 2023Date of Patent: December 19, 2023Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Shaojun Qiu, Nengwu Liao, Chao Guo, Tiefeng Wu

Publication number: 20230296315Abstract: The present application provides an oven drying apparatus and a coating device. The oven drying apparatus comprises an oven drying chamber and a heating assembly. The oven drying chamber is equipped with a first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber. The heating assembly is disposed on the first oven drying side. The first oven drying side is further provided with at least one air return portion provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber. The arrangement of an air return portion between two first air inlet portions can discharge fluid medium between the two first air inlet portions and take away the heat, thus avoiding accumulation of heat between the two first air inlet portions.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Yinxiang LIN, Peng JIN, Chao GUO, Nengwu LIAO, LIjun LI, Xuefeng KANG

Patent number: 11056683Abstract: An electrode plate processing device is provided. The electrode plate processing device includes: an electrode plate conveying mechanism configured to convey an electrode plate; a cutting mechanism disposed opposite to the electrode plate and configured to cut the electrode plate to form a tab; and a waste adsorption mechanism disposed downstream of the cutting mechanism along a conveying direction of the electrode plate. The waste adsorption mechanism includes an active driving roller, a driven support roller, and a conveyer belt that is coupled to the active driving roller and the driven support roller in a transmission way. The conveyer belt is driven by the active driving roller to rotate and configured to provide an adsorption force to a waste edge produced during the cutting of the electrode plate so as to adsorb the waste edge.Type: GrantFiled: March 26, 2019Date of Patent: July 6, 2021Assignee: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Tiefeng Wu, Xiangqiang Huang, Tao Zhang, Nengwu Liao, Shaojun Qiu, Yuhuai Yang
