[0002] With the growing demand for clean energy worldwide, the photovoltaic industry has shown rapid development in recent years. Solar energy, as a sustainable and pollution-free energy source, is increasingly widely used, including large-scale solar power plant construction and distributed rooftop photovoltaic power generation systems. In the production process of photovoltaic cells, silver paste is a key material, which is mainly used for the production of electrodes and plays an important role in collecting and conducting current. Its quality and supply stability directly affect the photoelectric conversion efficiency and production efficiency of photovoltaic cells.

[0003] Silver paste has low activity and poor flowability in natural state, which makes it difficult to be used for stable and continuous feeding operation. Traditional feeding methods usually do not fully consider the characteristics of low activity and poor flowability of silver paste, and lack effective processing mechanisms. For example, simply using a container to hold and directly pour or extract silver paste cannot guarantee uniform mixing and stable flow of the material during feeding. Therefore, this feeding method is prone to cause problems such as pipeline blockage, uneven feeding and component separation, which will affect the quality stability of photovoltaic cell electrode manufacturing, reduce production efficiency and increase cost. Especially in some small photovoltaic enterprises, due to the use of basic feeding equipment, silver paste often deposits or forms clumps in the pipeline, which requires frequent shutdown for cleaning, causing significant impact on production progress and economic benefits. In addition, traditional feeding technology cannot accurately control the amount and speed of silver paste feeding, which cannot meet the strict requirements of modern photovoltaic industry for automation and high-precision production.

[0004] Therefore, it is of great practical significance to develop a special feeding device that can effectively solve the problems of low activity and flowability of silver paste, which can significantly improve the production process level and product quality of the photovoltaic industry.
