AI Technical Summary

Technical Problem

In existing technologies, the detection of foreign objects inside lids and containers relies on manual visual inspection, which has problems of missed detection and false detection. It is difficult to meet the quality control requirements of industrialized mass production, and it is inefficient and cannot be adapted to high-speed automated production lines.

Method used

An automatic detection and rejection device for foreign objects inside lids and for defective products was designed. It uses an industrial camera and a gripping and transfer assembly, combined with a diversion wheel and a rejection actuator, to achieve automatic detection and rejection of foreign objects inside lids and containers.

Benefits of technology

It enables standardized and precise detection of foreign objects inside lids and containers, eliminating the problems of missed or incorrect detections by manual methods, improving detection efficiency, adapting to high-speed automated production lines, and reducing labor costs.

Abstract

The present application belongs to the technical field of foreign matter detection, and particularly relates to a device for automatically detecting foreign matter in a cap and automatically removing unqualified products, which comprises a rack, conveying tracks installed on the rack, a foreign matter detection assembly installed between two sections of the conveying tracks and used for collecting image signals inside bottles through an industrial camera; the foreign matter detection assembly comprises a detection box, a support base, a shunt wheel, a bottle-side industrial camera, a bottom industrial camera and a grabbing and transferring assembly; a removal execution mechanism I is installed in the detection box and used for removing unqualified bottles from the shunt wheel; and a removal execution mechanism II is installed on the conveying track on one side of a discharge port of the detection box; through the design of the automatic detection and integrated removal structure, the device automatically detects foreign matter in bottles (the cap and the container are connected with each other), inverted containers and caps, and fundamentally solves the problem of manual missed detection.
