Abstract:

Aiming at the problems of the tablets surface quality detection mainly depending on artificial naked eye judgment, low detection efficiency and missing detection, the research on intelligent identification, location and sorting robot technology for defective tablets was carried out, and the overall structure of the robot system was designed. The image recognition and processing software which Swritten by Halcon is used to identify and locate the defective tablets, and the forward and inverse kinematic analysis of the robot is carried out. The software is compiled to calculate the position information of tablets, and the robot joints are driven by instructions to grasp the defective tablets accurately, so as to realize the intelligent sorting of the defective tablets. The function of intelligent identification, location and sorting of defective tablets is validated by a practical scaling robot system. The robot system has the advantages of low cost, wide working range, accurate intelligent identification and location, and good generality.
