Abstract

The invention discloses a control system and a control method for photovoltaic chained equipment. The control system and the control method are mainly used in solar photovoltaic industries, achieve full automation operation and control of the chained equipment, and improve operation simplicity, practicality, safety and functional comprehensiveness of the equipment. The control system mainly comprises a computer used for man-machine interaction, a central controller controlling execution and correction, a detector detecting the operation state of the equipment, and execution units.

Description

technical field [0001] The invention relates to cleaning equipment in the solar photovoltaic industry, in particular to a control system and a control method for chain cleaning equipment and chain wet processing equipment. Background technique [0002] The manufacturing process of crystalline silicon cells in the solar photovoltaic industry is roughly divided into: silicon wafer - texturing - diffusion - deedge etching - dephosphorous silicon glass (PSG) cleaning - deposition of anti-reflection coating (PECVD) - silk Screen printing--sintering--test sorting--battery sheet. Among them, the "texturing", "de-edge etching", "PSG cleaning" and other processes have been realized by tank cleaning equipment (slot texturing, tank PSG removal) and dry etching equipment for many years. With the continuous development of the photovoltaic industry, the popularization of solar energy, a clean energy, requires solar cells to have higher photoelectric conversion efficiency, lower productio...
