The invention discloses a method for checking strip box glue points of a C800 high-speed packing machine. The method comprises: S1, installing a micro camera, a lighting source and a photoelectric switch, and connecting a controller, a photoelectric coupler and a touch display; S2, omnidirectionally scanning and photographing the glue points on strip box label papers passing through a strip box label paper conveying channel with the micro camera line by line, sending the taken pictures to the controller, and judging whether the glue points are defective through the controller; and S3, moving and counting the strip box label papers through the controller if judging that the strip box label papers are defective through the controller, and sending removal high-level signals to an original control system for removing the defectives automatically. The method disclosed by the invention has the beneficial effects that the glue points missing or reduced on the strip box label papers can be found in time, and the production process is not interrupted, so that the automatic detection and removal of products with defective glue points on the strip box label papers can be achieved; and the perfect matching of the detection speed and equipment running speed is achieved.
