Title:
PROCESSING SYSTEM, PROCESSING METHOD AND APPLICATION METHOD FOR COPPER MESH FOR BATTERY PIECE WITHOUT MAIN GRID
Document Type and Number:
WIPO Patent Application WO/2021/037019
Kind Code:
A1
Abstract:
The present application discloses a processing system, a processing method and an application method for a copper mesh for a battery piece without a main grid, which relate to the field of photovoltaic technology. The present application provides a novel copper mesh processing method, comprising: forming a copper wire interwoven structure by means of wire drawing modules, and further processing the copper wire interwoven structure into a required copper mesh by pressing and welding of upper and lower molds, copper wire guide grooves on the lower mold being able to prevent misalignment or relative offset between the copper wires. The copper mesh obtained by processing using the method provided in the present application does not require a backing, so that the problems of high processing difficulty and poor soldering caused by the backing can be avoided while achieving low cost of final products and high efficiency, and the processing and transportation costs of the supplier can be saved, improving the production efficiency, and reducing the material cost of the backing.
