AI Technical Summary

Technical Problem

The existing visual inspection equipment suffers from image acquisition deviation and insufficient detection accuracy due to the dynamic movement of the carrier along the conveyor line. Furthermore, the complex algorithms added to the existing equipment to alleviate this problem have led to high R&D costs and maintenance difficulties.

Method used

A product visual inspection device is designed, including a carrier, a conveyor line, a machine vision inspection unit, and a temporary lifting mechanism. The temporary lifting mechanism lifts the carrier and holds it in a preset inspection position when it is transported to the visual inspection area. The stability of the carrier is ensured by an overrunning thrust mechanism, a blocking limit mechanism, and a lifting mechanism.

Benefits of technology

It effectively avoids vehicle displacement or attitude deviation caused by mechanical vibration and conveying deviation, improves the stability and detection accuracy of image acquisition, reduces modification costs, and adapts to product parts of different sizes and shapes, meeting the needs of industrialized mass production.

Abstract

The invention relates to the technical field of machine vision detection, in particular to product part vision detection equipment which comprises a carrier, a conveying line, a machine vision detection unit and a temporary lifting machine. The conveying line conveys a carrier carrying a to-be-detected product piece; the machine vision detection unit is used for image acquisition; the temporary lifting machine is arranged below the conveying line, and when the carrier is conveyed to the visual inspection area, the carrier is temporarily lifted by the conveying line. Thus, on one hand, the phenomena of carrier displacement or posture offset and the like caused by mechanical vibration and conveying deviation are avoided, the product piece is always kept in a stable detection posture, and a guarantee is provided for improving the image analysis accuracy; on the other hand, the detection requirements of the products of different specifications can be met only by adjusting the preset detection position parameters of the temporary lifting machine; and after visual detection is completed, the carrier can fall back to the conveying line to continue to flow, and the overall detection efficiency is not affected.
