The design and implementation process of a drum brake pad molding production line was mainly introduced based on FANUC robot. On the basis of the existing molding technology and equipment, the automatic realization scheme was studied. Three 6-axis robots were used with corresponding truss, motion platform, transport car and automatic reclaimer to realize preform body pressing, preform body removal, preform body transportation, blowing chip & cleaning, spray mold release agent, preform body placement,product taking out, automatic collection and other actions, so the entire automatic process of molding production was realized.
