Problems solved by technology

[0003] Machine vision is used in the detection of mobile phone glass covers. For the imaging of the flat area of ​​the product, the current detection technology is very mature; for the curved area, due to the diffusion of light on the curved surface, the general lighting method Under certain circumstances, the arc surface cannot be imaged normally, so the detection of the arc surface area is a major detection problem in machine vision

Abstract

The invention provides a cambered surface detection device which is used for detecting a cambered surface area of a glass cover plate. The cambered surface detection device comprises a cambered surface light source, wherein the cambered surface light source comprises a plurality of sub-light sources which are sequentially arranged along the arc direction of the cambered surface light source; the cambered surface area of the glass cover plate is divided into a plurality of sub-planes which are sequentially arranged along the arc direction of the cambered surface area; the plurality of sub-lightsources correspond to the plurality of sub-planes one by one; and the sub-light sources are used for detecting the sub-planes. According to the cambered surface detection device disclosed by the invention, normal imaging of the cambered surface area of the glass cover plate can be realized, a micro-bright field imaging effect can be achieved, and the problem that tiny concave-convex points cannotbe imaged is solved. Correspondingly, the invention also provides a cambered surface detection method.

Description

Technical field[0001]The present invention relates to the field of optical detection. Specifically, the present invention relates to a curved surface detection device and a curved surface detection method.Background technique[0002]Due to the rapid development of machine vision technology, more and more industries have begun to choose machine vision technology to replace manual product quality inspection.[0003]Machine vision is used in the inspection of the glass cover of the mobile phone. For the imaging of the flat area of ​​the product, the current inspection technology is very mature; for the arc area, due to the diffusion effect of the arc surface, the general lighting method is Under the circumstances, the arc surface cannot be imaged normally, so the detection of arc surface area is a big detection problem in machine vision.Summary of the invention[0004]The purpose of the present invention is to provide a curved surface detection device, which can realize normal imaging of the...
