Research on a Robot Auto-sorting System Based on Machine Vision

Abstract

In view of the shortcomings of poor reliability and low efficiency in traditional workpiece sorting, a robot auto-sorting system based on machine vision is proposed in this paper. The system is mainly composed of vision unit, workpiece transport unit, robot unit, controller unit and servo drive unit. By analyzing the hardware and software algorithm of machine vision system, the PC and PLC are selected as controllers. Asynchronous motor is used as a power device for workpieces transmission, and pneumatic robot is used as sorting device. The experiment shows that the system can quickly and accurately identify workpiece and complete the assigned sorting.
