Device for detecting appearance defects of electroplated decorative part in real time and detection method thereof

Abstract

The invention discloses a device for detecting appearance defects of an electroplated decorative part in real time. The device comprises an image acquisition camera and a plate body used for placing a to-be-detected piece, a light source box is arranged above the plate body, an opening is formed in the light source box, the opening of the light source box faces the detection surface of the to-be-detected piece, the inner wall of the light source box is fixedly connected with a light uniformizing plate and a plurality of rows of high-brightness LED lamps which are distributed in an annular array and are used for irradiating the detection surface of the to-be-detected piece; and a lens of the image acquisition camera faces the to-be-detected piece and is used for receiving light which is emitted by the high-brightness LED lamps and is reflected by the detection surface of the to-be-detected piece. The light source box and the image acquisition camera are arranged on the plate body, so that the problem that the detection rate is reduced due to the fact that reflected light in a formed image is too strong is solved.

Description

technical field [0001] The invention relates to the technical field of digital image processing and image pattern recognition, in particular to a device for real-time detection of appearance defects of electroplated decorative parts and a detection method thereof. Background technique [0002] Electroplated decorative parts, especially automotive electroplated decorative parts, have the characteristics of high reflectivity, diverse and complex structures, multiple detection surfaces, and many types of defects. At present, manufacturers mainly use manual online detection of surface defects. The detection results are greatly affected by subjective factors such as people's energy, attention, mood, etc., and workers work in strong light for a long time, and they are prone to fatigue and symptoms such as dizziness. , the quality of the test results cannot be guaranteed. With the development of enterprises, traditional manual methods have been unable to meet the high-precision, f...
