Description

technical field [0001] The invention relates to the technical field of solution spraying equipment, in particular to a solution coating machine. Background technique [0002] In the current industrial production and processing process, especially in the processing and manufacturing process of photovoltaic module products, spraying operations are usually required, that is, the industrial solution is sprayed onto the carrier of the product to be processed so that the solution is coated on the surface of the product to be processed and Form thin films or similar functional structures. [0003] At present, in the existing coating operation process, it is usually necessary to spray the toxic solution, which requires the relevant coating equipment to have certain safety protection measures to avoid the leakage of the toxic solution during the process. However, although the existing coating equipment has a certain isolation structure, under continuous high-intensity operations, th...

AI Technical Summary

Problems solved by technology

However, although the existing coating equipment has a certain isolation structure, under continuous high-intensity operations, this simple isolation protection measure cannot effectively avoid the safety hazards caused by toxic solutions to the surrounding environment and operators

At the same time, because most of the existing coating equipment adopts static nozzles, the effective coating area is small and the coating efficiency is low, which cannot meet the needs of large-area continuous spraying operations.
