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 curved surface detection device for detecting the curved surface area of ​​a glass cover, which includes a curved surface light source, the curved surface light source includes a plurality of sub-light sources arranged in sequence along its arc direction, and the glass cover The arc surface area of ​​the plate is divided into a plurality of sub-planes arranged in sequence along the arc direction, the plurality of sub-light sources correspond to the plurality of sub-planes one by one, and the sub-light sources are used to detect the sub-planes. The curved surface detection device of the present invention can realize normal imaging of the curved surface area of ​​the glass cover plate, and can also achieve the micro bright field imaging effect, which solves the problem that fine concave and convex points cannot be imaged. Correspondingly, the present invention also provides a method for detecting a curved surface.

Description

technical field [0001] The invention relates to the field of optical detection, and in particular, the 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 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 light diffusion effect of the curved surface, the general lighting method In this case, the curved surface cannot be imaged normally, so the detection of the curved surface area is a major detection problem in machine vision. Contents of the invention [0004] The object of the present invention is to provide a curved surface detection device, which can realize normal ...
