Description

New energy automobile battery pole piece manufacturing installation Technical Field The application relates to the technical field of battery production and processing, in particular to a new energy automobile battery pole piece manufacturing device. Background New energy automobiles are an important solution for green travel, and are rapidly developed in recent years. The battery technology is a key core, and the production quality and efficiency of the battery pole piece have important influence on the battery performance. Along with the continuous expansion of new energy automobile markets, the requirements for the battery pole pieces are increased, and the development of related production technologies is promoted to meet the requirements of the markets on the battery pole pieces in aspects of quality, yield and the like. Meanwhile, the efficient and high-quality battery pole piece production technology is also beneficial to pushing the new energy automobile industry to develop towards the directions of more environmental protection and more energy conservation, reduces the dependence on the traditional fuel automobile, and has important significance for improving the environment and the energy structure. In the field of new energy automobile battery pole piece production, the existing production mode relies on a punch to finish the punching process of the pole piece. The punch press is a common device in the field of metal processing, and can punch and shape a metal material by strong pressure. In the production of the battery pole piece, the punch press is matched with a corresponding die to punch the metal foil so as to obtain the battery pole piece with the required shape. In addition, in the metal foil conveying process, a simpler conveying mode is generally adopted, and after preliminary flattening by a flattening machine, the metal foil is directly conveyed to a punching machine for punching. However, the punching equipment is bulky and requires a large space in the production shop, which not only increases the site cost but also limits the flexibility of the production layout. Meanwhile, it is difficult to convey the metal foil raw material into a punch press with a large volume, flatness and dimension uniformity of the battery pole piece cannot be guaranteed during conveying, and finally material waste and maintenance cost increase are caused.
