[0001] The present invention relates to the field of testing facilities, and in particular to an optical testing device and a testing method for defects in glass bottles. Background Art

[0002] In order to ensure that the produced glass bottles are of high quality and stable performance, optical inspection equipment is usually required to inspect the glass bottles to identify whether there are defects. When inspecting, the optical inspection equipment mainly collects images of the glass bottles through optical inspection image acquisition devices, and then uses image processing and analysis software to intelligently identify and analyze the images, identify defects in the glass bottles, and automatically remove them through a robot.

[0003] However, in the actual detection process, when the conveyor belt transports the glass bottle, the bottom of the glass bottle is blocked by the conveyor belt, which makes it difficult to capture the image of the bottom of the glass bottle when shooting.
