Rotary automatic light inspection machine

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automatic detection of foreign objects in bottles, in particular to a rotary automatic lamp inspection machine. Background technique [0002] At present, automatic light inspection machines are all aimed at the pharmaceutical industry. The cameras are placed outside the bottle body, and the images of the liquid inside the bottle body are taken through the bottle wall to determine whether there are impurities. For example, Chinese invention patents such as application number 201110203595.7 and application number 201210557961.3 all adopt this principle. This type of automatic light inspection machine cannot be used for spray-painted bottles, carved vases, and labeled bottles. At present, most liquor and beverages in the market use a wide variety of packaging bottles for aesthetics, and the market is not yet capable of these. Automatic detection equipment for impurities in bottled liquids. In addition, the...

This type of automatic light inspection machine cannot be used for spray-painted bottles, carved vases, and labeled bottles. At present, most liquor and beverages in the market use a wide variety of packaging bottles for aesthetics, and the market is not yet capable of these. Automatic detection equipment for impurities in bottled liquids

In addition, the current rotary automatic light inspection machine adopts the method of reciprocating motion of the camera to follow the shooting, which will cause the camera to repeat the acceleration and deceleration movement all the time, which will inevitably bring about vibration of the camera. The movement of the camera is exactly the same, that is, the camera and the bottle to be inspected cannot remain relatively still, so it will cause detection errors
