Abstract

The invention discloses a coating device and a coating method. The coating device comprises a first coating mechanism and a second coating mechanism, wherein the first coating mechanism is used for coating multiple rows of first coating areas arranged at intervals in the width direction of a base material or multiple lines of first coating areas arranged at intervals in the length direction of thebase material, the second coating mechanism is used for coating multiple rows of second coating areas arranged at intervals in the width direction of the base material or multiple lines of second coating areas arranged at intervals in the length direction of the base material, wherein the multiple rows of first coating areas and the multiple rows of second coating areas are arranged in a staggered manner in the width direction of the base material, or the multiple lines of first coating areas and the multiple lines of second coating areas are arranged in a staggered manner in the length direction of the base material. According to the coating device and the coating method, the residual of material pulp left in a blank area can be avoided, and the quality of battery pole pieces can be improved.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a coating device and a coating method. Background technique [0002] Lithium-ion batteries have been widely used in military and civilian electrical appliances due to their high energy density, wide operating temperature range, long cycle life and environmental protection. The preparation process of the battery directly affects the quality of the battery, so the preparation device and method of the battery are particularly important. The preparation of the battery pole piece needs to coat the base material. In some processes, it is necessary to leave a part of the blank area on the base material to form the battery pole piece. [0003] The inventors of the present application have found in long-term research and development that the current coating of battery pole pieces is to leave a blank area during the coating process of the substrate by scraping or vacuum sucti...
