In this paper，a fully automatic metallized spraying conveyor line for metallized film capacitor elements is introduced. The conveyor line transfers the rolled elements to the loading station，and then the mechanical arm grabs the elements and puts them into the elements frame. After that，the elements are sprayed on the suspension line along with the elements frame. Finally，the sprayed elements are completed off the line at the unloading station，while the empty elements frame returns to the loading station with the suspension line. Through such advanced manufacturing technologies as robots，radio frequency identification and automatic control，the automated operation of the entire elements spraying process is fully realized. This not only improves the efficiency，but also enhances the quality and stability of the spraying.
