Defect detection device for optical packaging element

The utility model relates to the technical field of optical packaging equipment, in particular to a defect detection device for an optical packaging element, which comprises a workbench, and a feeding disc, a feeding manipulator assembly, a detection working part, a discharging manipulator assembly, a discharging disc and a controller which are respectively arranged on the workbench, the controller controls the feeding mechanical arm assembly to grab workpieces to be detected from the feeding disc and place the workpieces to be detected on the detection working part, and the controller controls the discharging mechanical arm assembly to grab the detected workpieces from the detection working part and place the detected workpieces to the discharging disc. The defect detection device overcomes the defects that an existing detection method mainly depends on manual observation and judgment, the detection speed is low, and the detection result is inaccurate, can automatically, rapidly and accurately detect the def
