Shaft-type part appearance detection method based on linear camera

Abstract

The invention discloses a shaft-type part appearance detection method based on a linear camera. The shaft-type part appearance detection method comprises a fixed support, wherein the fixed support adopts a U-shaped structure, the fixed support is provided with a motor fixing frame, a rotating motor is installed on the motor fixing frame, a motor shaft of the rotating motor is connected with a rotating shaft, the outer end part of the rotating shaft is fixed on the center of a fixed plate, the fixed plate is installed on one side end surface of the to-be-detected shaft-type part, the to-be-detected shaft-type part is transversely arranged and is parallel to the ground, the inner side of the top of the fixed support is provided with a camera support and a switching plate, the camera supportis longitudinally provided with a channel, one end of the switching plate is fixedly connected with a bolt on the channel of the camera support, the other end is fixedly connected with a linear camera, the linear camera is arranged above the to-be-detected shaft-type part, the inner side of the bottom of the fixed support is provided with a backlight source, and the outer wall of the fixed supportis also provided with a monitoring terminal. The shaft-type part appearance detection method is simple in structure principle, capable of efficiently and precisely detecting the appearance of the shaft-type part, high in working efficiency, and capable of increasing the appearance qualification rate of the shaft-type part at the same time.

Description

technical field [0001] The invention relates to the technical field of shaft component detection, in particular to a method for detecting the appearance of shaft components based on a linear 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 misjudgments 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] The current appearance inspection of shaft parts is carried out by manual inspection or direct ca...
