ABSTRACT
Based on the longitudinal research topic “IC Plastic automatic feeding machine” research needs, firstly the issue of the overall technical program was designed, then the IC chip plastic packages automatic feeding system on the ponents was designed and the performance was tested. An automatic leader system was designed that realized automation for plastic package of integrated circuit. The system can be applied to the plastic package for DIP、QFP、SOP and TO series integrated circuits. The production efficiency and the product quality would be improved greatly. The system consists mainly of ponents, materials unit automatic film parts, puter systems, sensing detection system and the ponents and so on. The ponents of the automatic feeding machine was made by Sheet-metal structure, the structure is simple and easy to use. The ponents as an important ponents of the feeding machine, it play a role in supporting workstations, installation and protection of electronic equipment within various circuit modules, ponents and other ponents.
