Visual-based semi-closed sheet metal inner wall appearance detection device

Abstract

The application relates to the technical field of visual detection, and discloses a visual-based appearance detection device for the inner wall of a semi-closed sheet metal part. The application comprises a detection conveying table, a rack and a visual detection assembly; the visual detection assembly comprises a rotating mechanism and a reciprocating mechanism; the rotating mechanism drives a gear ring through a servo motor, drives a front shell body, in which a visual camera is installed, to rotate, and realizes comprehensive scanning of the inner wall in the circumferential direction; meanwhile, the reciprocating mechanism converts the motion into reciprocating swing of the visual camera itself by using a worm and a worm gear transmission and a swing arm connecting rod structure, covers omnidirectional detection, and effectively solves the problems of detection dead angles and low efficiency existing in traditional methods; the device is also provided with a wiring channel penetrating through the worm and a conductive slip ring, so that the continuous stability of power and signal transmission in the dynamic detection process is ensured; the device is compact in structure, high in automation degree, and significantly improves the comprehensiveness, accuracy and efficiency of detection.
