Endoscopic cavity component appearance detection method based on line-scan digital camera

Abstract

The invention discloses an endoscopic cavity component appearance detection method based on a line-scan digital camera. According to the method, a fixing bracket and a line-scan digital camera are mounted; the fixing bracket is of a U-shaped structure; a camera fixing column is mounted on the left side inside the fixing bracket; the camera fixing column is arranged perpendicular to the inner wallof the fixing bracket; one end of the camera fixing column extends into the inner cavity of a component to be detected; the component to be detected is of a hollow structure; the line-scan digital camera is fixedly mounted at one end of the camera fixing column; the right end of the component to be detected is fixed inside a clamping ring; a rotating shaft is fixedly connected with the middle of the outer side of the clamping ring; the rotating shaft is connected with a rotating motor which is arranged on a motor fixing rack; the motor fixing rack is mounted on the right side inside the fixingbracket; a monitoring terminal is mounted on the outer wall of the fixing bracket. The endoscopic cavity component appearance detection method is simple in structure principle and convenient to use,high-efficiency and high-precision detection on the appearance of the inner wall of an endoscopic cavity component can be achieved, the working efficiency is improved, and meanwhile, the component appearance pass percent can be increased.

Description

technical field [0001] The invention relates to the technical field of component detection, in particular to an endoscopic cavity component appearance detection method based on a line array camera. Background technique [0002] The appearance inspection system is mainly used to quickly identify the appearance defects of the sample, such as pits, cracks, warping, gaps, stains, sand, burrs, air bubbles, uneven color, etc. The sample to be inspected can be transparent or opaque ;In the past, product appearance inspection was generally done by naked eyes, so there may be human factors that lead to inconsistent measurement standards, and long-term inspections may cause misjudgment due to visual fatigue. With the in-depth cooperation of computer technology and optical, mechanical, electrical and other technologies, it has the characteristics of fast and accurate detection. [0003] At present, the appearance detection of the inner wall of endoscopic cavity parts is generally take...
