Modeling and simulation of glue spraying control system for optical fiber winding

The accuracy of the amount and uniformity of glue coating perform an important role in the stability and release property of the optical fiber bobbin. In manual glue application way, accuracy and uniformity of the coating are hard to precisely control and efficiency is very low. Based on characteristics of the applied glue and demands of optical fiber winding, a control system for automatic glue spraying was designed, which is made up of compressed air filtration and delivery subsystem, electrical proportional pressure valve, pressure transmitter, atomizer and programmable logic controller. In this paper, modeling and simulation of the control system were discussed. The simulation results indicate that the accuracy of pressure can be reached to 0.02MPa, which means that the system can perform a precise control of glue spraying volume.
