The overall design scheme of the fully automatic SMT type DC variable frequency rotor production line is shown in Figure 2. This line consists of 18 main parts: a double speed chain conveyor line, an iron core positioning/online workstation, 2 rivet insertion workstations, a riveting workstation, an iron core rolling workstation, a laser marking workstation, an iron core gluing workstation, a magnetic sheet mounting workstation (2 workstations for pre mounting), a gluing workstation, a magnetic sheet geometric positioning workstation, a rotor array furnace entry workstation, a rotor sintering solidification and cooling workstation, a rotor furnace release and disassembly workstation, a rotor rotation detection workstation, a rotor maximum radius detection workstation, a finished rotor offline workstation, and an electrical control system. Main technical parameters Power supply 380 V Air supply 0.5~0.7 MPa Gross power 12~16 KW Method of putting iron core on product…
