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

Abstract

The invention discloses a visual inspection error prevention system and a position correction method for articles transported by a conveyor belt, and belong to the field of visual inspection. The system comprise a camera, wherein the camera is erected above a conveying device through a camera bracket; and the system is characterized in that the color of a carrying platform of the conveying deviceis more than one, the various colors are arranged on the carrying platform in a staggered mode, the camera is connected to a controller, and the communication end of the controller is connected to a control system of the conveying device; and an induction device is arranged and used for detecting the advancing position of the conveying device, the signal output end of the induction device is connected to the controller, and the controller controls the camera to shoot after receiving a control signal of the induction device. According to the system, detection interference caused by corresponding consistency of the color of the detected object and the color of the detected object carrying platform is avoided, whether the object is in the center of the carrying platform or not can be detected, and object deviation data can be calculated.

Description

technical field [0001] The invention provides a visual detection error prevention system and a method for correcting the position of items 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 work can greatly improve the efficiency of goods sorting. The conveyor belt system includes an incoming system, waybill code scanning system, sorting system, revolving conveyor belt and 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. Due to the limitation of the size of the site and the need to set the location of the process, the conveyor belt system is hovering in the factory building, so there will be many b...

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.
