Description

Technical Field

[0001] The utility model relates to the technical field of energy storage device processing, in particular to a dust removal and expanding device for a cylindrical battery shell. Background Art

[0002] A battery is an energy storage device that can store electrical energy. A battery generally refers to a cup, trough, or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. Now it also refers to a small device that can generate electrical energy. Common energy storage batteries include lithium-ion batteries, sodium-ion batteries, lead-acid batteries, nickel-metal hydride batteries, supercapacitors, etc. Electrolyte is an important component of common chemical batteries. As a battery discharge medium, it provides ion conduction for the normal operation of positive and negative electrodes. Products such as lithium-ion batteries and sodium-ion batteries usually include metal shells, batteries arranged inside the metal shells, sealing rings, end caps and other components. Taking cylindrical batteries as an example, during the production and processing process, after the metal shell is made, the end of the metal shell needs to be expanded to facilitate the subsequent installation of batteries into the shell and sealing rings, end caps and other components. At the same time, in order to prevent dust impurities from affecting the performance of the subsequent battery, it is also necessary to remove dust from the inside of the metal shell to remove dust impurities inside the metal shell. In traditional operations, the two processes of expanding and dust removal are separate, that is, after the metal shell is expanded by the expanding equipment, it is collected and transported to the dust removal equipment for dust removal. This not only increases the transfer time, but also easily causes damage or contamination to the metal shell during the transportation process. Utility Model Content
