Abstract

The invention discloses a solar cell silk-screen printing screen device and an installation method thereof. The device comprises a screen frame and bowl-shaped screen cloth, wherein the screen frame comprises a square outer frame body and a round inner frame body, the portion, on the inner side of the square outer frame body but on the outer side of the round inner frame body, of the screen frame is solid, and the portion, on the inner side of the round inner frame body, of the screen frame is hollow. The bowl-shaped screen cloth comprises a bowl-shaped screen cloth bowl opening, a bowl-shaped screen cloth bowl bottom and bowl-shaped screen cloth bowl rims for connecting the bowl-shaped screen cloth bowl opening with the bowl-shaped screen cloth bowl bottom. The bowl-shaped screen cloth bowl opening is fixed to the round inner frame body of the screen frame. The bowl-shaped screen cloth bowl bottom is provided with printed patterns. The bowl-shaped screen cloth bowl rims are symmetrically distributed in the round inner frame body of the screen frame and around the printed patterns. By means of the technical scheme, the problem that slurry is scratched to the edges of the printed pattern, cakes and becomes dry, and consequently printing quality issues and slurry waste are caused is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of solar cell production tools, in particular to a solar cell screen printing screen device and an installation method thereof. Background technique [0002] Solar energy is a clean, efficient and inexhaustible new energy source, and it is one of the important renewable energy sources. With the development of the solar industry, more customers and solar cell manufacturers pay more and more attention to printing quality and paste loss. In recent years, a lot of research has been carried out on the printing quality of photovoltaic cells and the loss of paste at home and abroad. The results show that the main body of the paste is a metal material with fluidity, and the printing quality is easy to continue to expand under the inducement of the environment. The biggest influence on printing quality is temperature and humidity. In the northwest region where photovoltaic cells are produced, the climate is dry and...
