The backplane in the photovoltaic module is a fluorine-containing plastic,which has low recycling value and is easy to produce environmental pollution,and needs to be removed in advance for centralized treatment.In order to study the advantages of ultrasonic elliptical vibration cutting(UEVC)in removing the fluorine-containing backplane of retired photovoltaic modules,simulation experiments are carried out to compare UEVC with conventional cutting(CC),and single factor simulation experiments with cutting speed,cutting depth,tangential amplitude and frequency as variables are carried out for UEVC.The simulation results show that the cutting temperature and cutting force are positively correlated with cutting speed and cutting depth,and negatively correlated with tangential amplitude and frequency during UEVC.The cutting force is most significantly affected by the cutting depth.Compared with CC,UEVC can significantly reduce the cutting force and cutting temperature,in which the main cutting force is reduced by 43%,and the cutting temperature is reduced by 11%,which is an effective processing method to remove the fluorine backplane of decommissioned photovoltaic modules without pollution.
