Omnibearing high-precision detection device and method for defects of notebook computer shell

Abstract

The invention discloses an omnibearing high-precision detection device and method for defects of a notebook computer shell . The detection device is composed of an industrial personal computer, an image acquisition module, a lower computer control module, a conveying belt, a cover turning mechanism and a jacking rotating mechanism. The industrial personal computer and the lower computer control module control the notebook computer to stop when the notebook computer arrives at a specified detection station, and the cover turning mechanism and the jacking rotating mechanism are controlled by the servo motor to cooperatively act to adjust the angle of each surface of the notebook computer, so that the image of each surface of the notebook computer is acquired by the image acquisition module and provided for the industrial personal computer; after classification and fusion of multiple acquired images of various surfaces, image feature-defect form classification and identification are carried out. According to the invention, all-directional high-precision detection of the defects of the notebook computer shell can be realized.

Description

technical field [0001] The invention relates to an omnidirectional and high-precision detection device and method for defects in a notebook computer casing. Background technique [0002] Defects such as scratches, bumps, and pits will exist on the surface of the notebook computer case. At present, manual inspection is usually used to detect surface defects on the notebook computer case. Manual inspection has problems such as long detection time, different standards, and high cost. In addition, visual inspection In the system, a shooting camera often only shoots from one angle. If the shooting angle is not in place, the accuracy of defect detection will decrease, and the detection efficiency will be seriously reduced. Contents of the invention [0003] The present invention aims to solve the shortcomings of the above-mentioned prior art, and proposes a comprehensive and high-precision detection device and method for notebook computer casing defects, in order to realize mult...
