AI Technical Summary

Technical Problem

Existing one-click inspection stations based on machine vision are prone to radial runout during workpiece rotation, resulting in inconsistent distances between the inspection surface and the vision inspection device, poor image acquisition clarity and feature consistency, large deviations in dimensional measurement data, and low defect identification accuracy.

Method used

A contour-finding and distance-fixing platform is adopted. The contour plate fits the outer contour of the workpiece, driving the elastic collar to form synchronously. The spring preload and roller abutment are used to ensure that the workpiece detection surface and the detection device maintain a fixed distance. Combined with the motor driving the workpiece to rotate, radial displacement is limited.

Benefits of technology

It effectively avoids the fluctuation of the detection surface distance caused by radial runout, improves image clarity and feature consistency, and significantly improves the accuracy and precision of size measurement and defect identification.

Abstract

The application discloses a one-key detection table based on machine vision, which comprises a workbench, a detection device fixedly connected to the upper surface of the workbench, a groove and a guide rail arranged in the workbench, the guide rail being located at the bottom of the groove and being through the groove, a sliding block slidingly arranged in the guide rail, and a contouring distance platform arranged on the sliding block and used for copying the outer contour of a workpiece so that the detection surface of the workpiece always keeps a fixed distance from the detection device. Through the above components, the distance fluctuation problem of traditional rotary detection can be effectively avoided, the image consistency is improved, and the precision and accuracy of size measurement and defect identification such as scratches and burrs are significantly improved.
