Description

Technical Field

[0001] The utility model relates to the field of silver-coated copper powder production, in particular to an automatic multi-region filtering and cleaning mechanism for silver-coated copper powder. Background Technique

[0002] With the development of the electronic industry, the replacement of precious metals such as silver and palladium by base metals in the electronic industry has attracted more and more attention. Among them, copper, as one of the ideal substitutes for silver, has the advantages of low price, small resistivity, and small electromigration speed. As a functional material, copper powder has excellent electrical conductivity, thermal conductivity, and catalytic performance, and has important uses in electromagnetic shielding, chemical catalysts, conductive pastes, powder metallurgy and other fields. Due to the large specific surface area and active chemical properties of ultrafine copper powder, it is easy to form a dense Cu_2O and CuO film on the surface, which makes it difficult for conductive materials to maintain good electrical conductivity during long-term use.

[0003] Copper has good electrical conductivity and thermal conductivity, and is inexpensive. Compared with silver, it has a huge price advantage. However, the main disadvantage of copper is its unstable chemical properties and poor antioxidant ability, especially in humid and high-temperature environments, which cannot meet the requirements of photovoltaic pastes. The purpose of developing silver-coated copper ultrafine powder is to replace silver powder: it can not only meet the requirements of photovoltaic pastes, but also has a huge price competitive advantage. The essence of cost reduction of silver-coated copper is to replace a part of silver in silver paste with base metal copper, cover copper with silver, and continuously adjust the doping ratio of silver and copper through experiments to improve the photoelectric conversion efficiency and reduce the cost of silver paste while ensuring a certain efficiency. Silver-coated copper powder is prepared on the basis of ultrafine copper powder products, and the quality of ultrafine copper powder will directly affect the performance of the final silver-coated copper.

[0004] At present, the filtration of silver-coated copper powder is to conduct single filtration on the precipitated silver-coated copper powder through a filter membrane. It is necessary to open the filtration equipment to take out the filtered silver-coated copper powder and replace the filter membrane every time, which is rather laborious and has a high labor intensity. This application aims to conduct multiple filtrations on the precipitated silver-coated copper powder solution, set up a mobile filtration table to facilitate the replacement of the filter membrane inside the filtration table and the transportation of the filtered solid silver-coated copper powder, and intelligently fix and seal the multi-layer filtration settings, so as to realize the automatic filtration of the silver-coated copper powder solution and reduce the labor intensity of operators.
