Full-automatic vision detecting machine with accurate detection result

Abstract

The invention relates to the technical field of vision detection, and discloses a full-automatic vision detecting machine with an accurate detection result. The full-automatic vision detecting machinecomprises a base, a guide rail is installed at the top of the base, a movable table is installed at the top of the guide rail, an infrared distance sensor is installed at the top of the movable table, and supporting rods are installed on the left side and the right side of the base respectively. By arranging a conveying belt, articles are conveyed to a crawler belt through the conveying belt, when the articles pass through the infrared distance sensor, a signal detected by the infrared distance sensor is fed back to a control cabinet, when the sizes of the articles are too large, a motor is started, a gear rotates, an installing plate is meshed with a toothed plate through the gear so that two detectors can get close to each other, pictures of the articles are shot together, and it is avoided that a single detector conducts reciprocating shooting detection. When small articles are shot, the two detectors conduct shooting detection, pictures which are shot before and after are compared, and the aim of the accurate detection result is realized.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a fully automatic visual inspection machine with accurate detection effect. Background technique [0002] Visual inspection is to use machines instead of human eyes for measurement and judgment. Visual inspection refers to converting the captured target into image signals through machine vision products (ie, image capture devices, divided into CMOS and CCD), and sending them to dedicated image processing. The system, according to the pixel distribution, brightness, color and other information, is converted into a digital signal; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment action according to the result of the discrimination. It is used for production and assembly. Or a valuable mechanism of packaging that is invaluable in its function of detecting defects and preventi...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a fully automatic visual inspection machine with accurate detection effect, which has the advantages of accurate detection effect, etc., and solves the problem that the traditional visual inspection uses a single machine vision product to capture images, and the process of capturing shapes For large items, since the ingestion area of ​​the machine vision product is fixed, it needs to be reciprocated for ingestion many times. When ingesting small items, when a single machine vision product ingests images, the image will change continuously, which will lead to The problem of inaccurate detection
