Material detection system

According to the material detection system disclosed by the utility model, the robot is connected with the picking mechanism, the picking mechanism is provided with the at least two grabbing pieces, and the grabbing pieces can rotate relative to the bearing platform, so that the grabbing pieces can be moved to a designated position to grab at least two materials under the driving of the robot; the at least two materials are transferred to the corresponding detection mechanisms, and the grabbing piece is matched with the rotation control of the grabbing piece relative to the bearing platform, so that the defect detection of a plurality of parts of the materials is completed one by one, the detection comprehensiveness is ensured, and meanwhile, the problems of poor workpiece consistency and low detection efficiency caused by repeated turnover of the workpieces are also reduced; a plurality of detection stations are integrated into one detection mechanism, so that the size of the whole machine is reduced, and th
