The glue line appearance detection method according to claim 6, wherein the preset parameters include: a glue path width parameter, a glue path position offset parameter and a glue path bubble area parameter; judging whether the width of the glue path, the position of the glue path and the bubble condition in the glue path meet preset parameters or not, comprising the following steps:
Judging whether the width of the rubber path meets the width parameter of the rubber path or not;
If the rubber path width parameter is met, judging whether the rubber path position meets the rubber path position offset parameter or not;
And if the glue path position deviation parameter is met, judging whether the bubble condition in the glue path meets the glue path bubble area parameter.
9. A glue line appearance detection device, comprising:
The original image acquisition module is used for acquiring an original image of the glued flexible film;
The original image analysis module is used for carrying out BOLB analysis on the original image and determining a glue path image in the original image;
The glue path characteristic judging module is used for judging whether the glue path image accords with preset glue path characteristics or not;
And the detection result output module is used for determining the glue path detection result of the glued flexible film according to the glue path image if the glue path image accords with the preset glue path characteristics.
10. An electronic device comprising a processor and a memory, the memory storing computer-executable instructions executable by the processor, the processor executing the computer-executable instructions to implement the gum appearance detection method of any of claims 1-8.
