Air dryer of screen plate

Abstract

The invention relates to the field of drying of solid materials or products without heating, and particularly relates to an air dryer used for drying a photovoltaic cell piece screen plate. In the current process of manufacturing the screen plate by solar cell manufacturing enterprises, the screen plate is commonly dried by a manual manner and the manual drying of the screen plate has the problems that the drying time is long, the efficiency is low, the drying effect is not ideal, the drying quality is not easy to control and the like, so that the requirements of industrial large-batch production cannot be met. The invention discloses an automatic screen plate air dryer; clean compressed air with adjustable temperature, humidity and air speed can be used for drying the screen plate; the drying efficiency is high and the drying effect is hood; in a drying process, the screen plate and a printing pattern thereof are not damaged and the requirements of the industrial large-batch production are met. The air dryer is simple and compact in design, easy to implement and lower in energy consumption cost; the air dryer is suitable for large-batch drying treatment on a plurality of solid parts and has a wide application and popularization prospect.

Description

technical field [0001] The invention relates to the field of non-heating drying of solid materials or products, in particular to an air dryer for drying photovoltaic cell screen plates. Background technique [0002] With the increasingly tense global oil supply, various green energy industries are booming. Due to the advantages of green, low-carbon, and environmental protection, solar energy is developing rapidly. The related solar cell manufacturing machinery and R&D and production industries have sprung up and developed very rapidly. An effective way to convert solar energy into usable energy is to use crystalline silicon solar cells for photoelectric conversion, which can effectively absorb solar radiation and convert it into electrical energy. By the end of 2013, China had become the world's largest producer and installer of solar cells. [0003] The main production process of crystalline silicon solar cells is shown in the appendix figure 1 Among them, screen printin...
