The invention provides a rotary automatic light inspection
machine. The rotary automatic light inspection
machine comprises a rotary conveying device, a single-head detection device and a rejection device, wherein the rotary conveying device is used for realizing constant-speed stable forward motion of to-be-detected bottles on a rotary disc so as to acquire
assembly line time of detection, the single-head detection device is used for realizing
foreign substance detection of liquids in the bottles, and the rejection device is used for rejecting bottles containing impurities. According to the rotary automatic light inspection
machine, a
light source and a detection camera are mounted in the position, where each
bottle is located, of the rotary disc, the motion of the detection device is completely consistent with that of the bottles, the detection device and the bottles are in completely relative rest, and the detection precision is guaranteed; the endoscopic type intelligent cameras directly extend into
bottle openings for detection, and the rotary automatic light inspection machine can be used for detecting foreign substances in special-shaped bottles such as a glass
spray bottle, a wall-carved
bottle, a bottle with a brand and the like, thereby being widely applied to in-bottle
foreign substance detection of industries such as baijiu, beverages and the like.
