Appearance defect detection device based on 360 degrees of inner ring

Abstract

The invention discloses an appearance defect detection device based on 360 degrees of an inner ring. The device comprises a mounting side plate, an automatic object distance detection assembly, a camera, a stroboscopic angle light source, an inner ring detection lens, an automatic image distance adjusting assembly and an automatic light source adjusting assembly, wherein the automatic image distance adjusting assembly is fixed on a support plate a, the camera is fixed on the automatic image distance adjusting assembly through a support plate b, the inner ring detection lens is connected with the automatic image distance adjusting assembly through a support plate c, and the stroboscopic angle light source is fixed with the automatic light source adjusting assembly through a support plate d.According to the appearance defect detection device, the inner wall of a component can be subjected to image detection by the added inner ring detection lens, detection of the component is more comprehensive and more thorough, by the added automatic image distance adjusting assembly and automatic light source adjusting assembly, interval adjustment and control are more intelligent and more precise, interval data corresponding to certain component type can be stored, and the interval can be adjusted without deviation when the component is measured next time.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a 360° appearance defect detection device for an inner ring. Background technique [0002] Image detection is based on CCD digital images, relying on computer screen measurement technology and powerful software capabilities of spatial geometric calculations. After the computer is installed with special control and graphic measurement software, it becomes a measurement with a software soul. The brain is the main body of the entire device. It can quickly read the displacement value of the optical scale, and obtain the desired result in an instant through the calculation of the software module based on the space geometry; It can intuitively distinguish possible deviations in the measurement results. [0003] In the existing component image detection technology, generally only the front and back of the detection component can be image detected. For some components in the cav...

Problems solved by technology

[0003] In the existing component image detection technology, generally only the front and back sides of the detection component can be image detected. For some components in the cavity, it is difficult to fully reflect the overall image of the component, so it is easy to have defective products It has entered the market due to incomplete detection. In addition, the light source of the current image detection equipment and the adjustment of the shooting image distance are all dependent on manual work, which leads to low efficiency of spacing adjustment, and lack of quantitative data support leads to deviations in the next spacing adjustment.
