Abstract:Based on the analysis of the structure and assembly features of the new international standard elevator landing door, a set of automatic assembly scheme is presented based on industrial robot. The system was mainly composed of a plank loading unit, gluing unit, stiffener laying unit, robot-based clinching device, preserving unit, security unit and control unit, and etc. Based on programmable logical controller (PLC) and a superior industrial personal computer (IPC), the control unit was designed, which could realize data transmission between the robot and the main control PLC by using DeviceNet protocol. The entire production process of system was monitored though a touch screen and the configuration software running on the PC. The glue and clinching operation of elevator landing door could be automatically completed by the system, realizing the automatic assembly of the new international standard elevator landing door. As a result of practice, the system improves the automation level of the factory, reduces the labor intensity and labor cost.
