Visual inspection error prevention system and position correction method for items transported by conveyor belt

Abstract

The invention discloses a visual inspection error prevention system and a method for correcting the position of articles transported by a conveyor belt, belonging to the field of visual inspection, comprising a camera, and the camera is erected above a transportation device through a camera bracket, and is characterized in that the color of the carrying platform of the transportation device is More than one, various colors are alternately arranged on the carrying platform, the camera is connected to the controller, and the communication end of the controller is connected to the control system of the transportation device; an induction device is installed, the induction device detects the traveling position of the transportation device, and the The signal output end is connected to the controller, and the controller controls the camera to shoot after receiving the control signal from the sensing device. The present invention avoids the detection interference caused by the color of the detected article corresponding to the color of the detected article carrier platform, and can detect whether the article is in the center of the carrier platform, and can calculate the data of the article deviation.

Description

technical field [0001] The invention provides a visual detection error prevention system and a position correction method for articles transported by a conveyor belt, belonging to the field of visual detection devices. Background technique [0002] When sorting express parcels, the conveyor belt system will be used to automatically sort the goods. Using the conveyor belt system instead of manual labor can greatly improve the efficiency of goods sorting. The conveyor belt system includes an infeed system, a waybill code scanning system, a sorting system, a revolving conveyor belt and a control system. The revolving conveyor belt is composed of distribution conveyor belts connected in sequence, and the movement direction of the distribution conveyor belt is perpendicular to the revolving conveyor belt. Because the size of the site is limited and the process location needs to be set, the conveyor belt system is hovering in the factory building, so many curves will be set in the...

Problems solved by technology

However, the belts of the currently used conveyor belt systems are generally of a single color

The color of the package is various. If the color of the package is the same or similar to the color of the conveyor belt, it will affect the detection of the vision system, resulting in the situation that the edge cannot be judged, and the vision system cannot be used to solve this problem.
