Screen gluing quality detection device and detection method

The invention belongs to the technical field of screen gluing detection, and particularly relates to a screen gluing quality detection device and method, and the device comprises a positioning mechanism for positioning a product, a gluing quality detection mechanism for detecting the gluing quality of the product, and a visual system for processing image information. The positioning mechanism comprises a first CCD camera, a first telecentric lens and a first coaxial light source; an image shot by the first CCD camera is transmitted to the visual system, and the visual system processes image information so as to position the product; the gluing quality detection mechanism comprises a second CCD camera, a second telecentric lens, a second coaxial light source, a strip light source and a mini line light source which are sequentially arranged downwards in the vertical direction; the first coaxial light source is used for generating vertical light to act on plane back glue of a product, and light generated by the
