Equipment for detecting foreign matter in bottles and bottle-gripping and rotary device thereof

Abstract

The invention discloses equipment for detecting foreign matter in bottles, comprising a bottle-gripping and rotary device, an image collector which is arranged at one side of a bottle and is used forcollecting images of rotary liquid in the bottle, and an image processing device for judging whether foreign matter exists in the liquid in the bottle, wherein, the bottle-gripping and rotary device comprises a bottle rotating sleeve which is supported at a supporting seat and driven to rotate by a drive mechanism, a clamping jaw seat which is connected with the bottle rotating sleeve and can rotate with the bottle rotating sleeve, a clamping jaw in pin-jointed connection with the clamping jaw seat with the bottom end thereof being provided with a clamping block for clamping bottleneck and thetop end thereof being in pin-jointed connection with one end of a connecting rod, a pull rod positioned in the bottle rotating sleeve with the bottom thereof being connected with the other end of theconnecting rod, and a lifting mechanism arranged at the upper end of the pull rod for driving the pull rod to move in the bottle rotating sleeve. The invention has the advantages of avoiding the defect of missed detection due to foreign matter depositing at the bottom of the bottle when the foreign matter in the bottle rotates with the bottle and using the clamping jaw to only clamp the bottleneck which is in favor of collecting images of the foreign matter.

Description

technical field [0001] The invention relates to the field of visual detection of mechanical packaging, in particular to a detection device for foreign matter in a bottle and a bottle grabbing and rotating device for detecting foreign matter in a liquid. Background technique [0002] At present, there are relatively few equipments in China that use industrial cameras to detect foreign objects in bottles, and they are mainly distributed in the fields of ampoules, vials, and oral liquid bottles. In some equipment, a magnifying glass is used to detect on the conveying track; some use a clamped bottle body for detection. [0003] Among them, when a magnifying glass is used to detect on the conveying track, foreign matter such as debris deposited on the bottom of the bottle is easily missed, resulting in inaccurate detection; while when the bottle is clamped for detection, the clamped part of the bottle is blocked , the test results are also inaccurate.
