Embodiment Construction

[0068] As described above, the current method of relying on inspectors to manually detect defects of the object under test (such as curved glass) has the problem of low efficiency. In order to solve this problem, the inventor provides a detection device and a detection method after research, which can realize automatic detection for the defects of the object to be tested.

[0069] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope...

Abstract

The invention discloses a detection device and a detection method. The device comprises a light ray generating device and an imaging device. The light ray generating device comprises a stripe pattern,the device is used for emitting light beams and projecting the stripe pattern to the object to be detected through the light beams, and the stripe pattern comprises a plurality of separated straightstrips which are arranged in parallel; the imaging device is used for obtaining the light beam transmitted or reflected by the object to be detected to form a detection image, and the detection imagecomprises a plurality of stripes; and the detection image is used for acquiring the defect information of the object to be detected according to the stripes. If the surface of the object to be detected is processed ideally and without defects, the detection image obtained by the imaging device should demonstrate straight stripes similar to the stripe pattern. However, if the surface of the objectto be detected has defects, such as orange lines, die scratches, indentations, and the like, the stripes in the detection image are distorted. The detection device can be used for automatically detecting the surface defects of the object to be detected, and compared with the manual detection method in the prior art, the detection efficiency is significantly improved.

Description

technical field [0001] The present application relates to the technical field of defect detection, in particular to a detection device and a detection method. Background technique [0002] Glass materials are widely used in modern industrial manufacturing, such as using glass materials to make mobile phone cases, lenses, battery sheets, and display screens. With the progress and development of processing technology, more and more glass products are designed with curved surface structure, so that the product can better realize the function or achieve a more beautiful effect. [0003] Since the processing of glass curved surfaces requires more and more complicated processes, various defects with different characteristics will inevitably occur during the production process. The common appearance defects include scratches, bumps, mold scratches, orange lines, and indentations. , edge collapse, etc., which affect the function realization and aesthetic effect of the product. Ora...
