Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to a large-scale production device of nano-silver paste. Background technique [0002] Silver materials are widely used in conductive pastes because of their good electrical conductivity and chemical stability. According to relevant data, in 2016, 561.9 million ounces of silver (about 16,000 tons) were consumed in the industrial manufacturing field, of which 233.6 million ounces were consumed in the electrical and electronic field, 55.4 million ounces were consumed in the welding field, and 76.6 million ounces were consumed in the photovoltaic field. ounces, most of which need to use conductive silver paste. It can be seen that the market scale of silver conductive paste is very large, but the current silver paste mainly uses micron-sized spherical or flake silver particles as conductive components.

According to relevant data, in 2016, 561.9 million ounces of silver (about 16,000 tons) were consumed in the industrial manufacturing field, of which 233.6 million ounces were consumed in the electrical and electronic field, 55.4 million ounces were consumed in the welding field, and 76.6 million ounces were consumed in the photovoltaic field. ounces, most of which need to use conductive silver paste. It can be seen that the market scale of silver conductive paste is very large, but the current silver paste mainly uses micron-sized spherical or flake silver particles as conductive components. In order to reduce costs, researchers Focusing on the development of nano-silver materials, the conductive paste with nano-scale silver particles as the main component can produce thinner and thinner circuits, thereby reducing costs, improving the integration of electronic products, and reducing the cost of electronic devices. quality, and with the development of printed electronics technology, electronic and electrical devices are developing in the direction of flexibility and wearability. Only nano-scale silver conductive paste can meet the requirements of various printing technologies. Therefore, in the future, nano- The demand for silver paste will increase

[0003] Although there are many types of nano-silver paste production devices on the market today, most of them are only changes in form, and their functions have not changed much. Today's nano-silver paste production devices are usually connected to multiple separate production equipment. For production work, the structure is more complicated, the labor force and workload are increased, and the degree of automation is low. Therefore, a large-scale production device for nano-silver paste is needed to change the status quo
