The invention discloses an intelligent detection system for defective products of semiconductor devices, and relates to the technical field of semiconductors. According to the intelligent detection system for the defective products of the semiconductor devices, the discharging mechanism can achieve automatic discharging in the detection process, after the conduction detection mechanism is used for conducting detection on the diodes, the appearance detection mechanism is used for detecting whether the outer surfaces of the diodes have cracks or abnormal deformation or not, the detection process is high in automation degree, and the detection efficiency is high. Continuous detection work of the diodes can be realized, and the qualified rate of the diodes is improved. According to the diode loading mechanism, 360-degree overturning of the diode can be achieved through meshing of a gear and a rack in the detection process and the action of friction force between the diode and a cleaning roller, all-directional de
