judging that there is an abnormality between the glass substrate and the spacer paper in any of the following cases:
the distance between the left edge of the glass substrate and the left edge of the spacing paper is not within a preset threshold range;
the distance between the right side edge of the glass substrate and the right side edge of the spacing paper is not within a preset threshold range;
the distance between the lower end edge of the glass substrate and the lower end edge of the spacing paper is not within a preset threshold range;
the edge surrounding part of the glass substrate is provided with a spacing paper edge;
the outline of the glass substrate does not correspond to the preset product outline;
cracks exist in the glass substrate; and outputs an alarm signal when there is an abnormality.
6. The glass substrate packaging quality monitoring system of claim 5, further comprising:
the PLC is in communication connection with the upper computer and is used for sending a packaging starting signal and a packaging ending signal of the glass substrate to the upper computer and receiving an alarm signal;
the database is connected with the upper computer and is used for storing the production information of the glass substrate, the tracing video of the glass substrate, the file name of the tracing video and the file path information;
the upper computer is also used for responding to the received package starting signal, controlling the video acquisition device to acquire the video, and responding to the received package ending signal, controlling the video acquisition device to stop video acquisition.
