Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, and in particular to a glass cover plate testing device. Background Technology

[0002] The descriptions in this section provide background information relevant to this disclosure only and do not constitute prior art.

[0003] Currently, in the inspection of cover glass, for products that have been inspected by automatic inspection machines, the method of illuminating the sample with a light source and then using a background projection method is mostly used to detect appearance defects such as stones, nodules, and glass ridges on the cover glass. Compared with manual inspection, this method improves inspection efficiency.

[0004] The color of the background plate affects the detection. A white background plate provides higher brightness reflection, making impurities more visible and easier to detect. However, a white background plate may be affected by ambient light, resulting in reduced contrast and making it difficult to observe fine impurities. A black background plate can absorb more ambient light, reduce interference, and improve contrast, making impurities stand out more against a dark background. However, a black background plate has lower reflectivity, which may make some light-colored impurities difficult to detect. Therefore, in practical use, it is best to use both white and black background plates. This creates the problem of cumbersome replacement of the two background plates, and the replaced background plates are not easy to store, and improper storage can lead to soiling.

The bottom surface of the transparent outer shell 1 is fitted with a back panel push-up structure 8 at the position corresponding to the white back panel 9.

[0024] Specifically, in this embodiment, the transparent outer shell 1 is rectangular and made of transparent acrylic material, and is used in a dimly lit indoor environment; Furthermore, two background panels, white 9 and black 10, are inserted into the transparent housing 1. The front back panel is used for projection. When the front back panel is not the desired color, the back panel push-up structure 8 is activated to push the front back panel upward and extend it out of the first strip window 6, thus removing the front back panel. Subsequently, the back panel push-forward structure 7 is activated to push the rear back panel forward to its maximum stroke. At this point, the forward-moving back panel is in the original position of the front back panel. The process of changing the colors of the white back panel 9 and black back panel 10 is semi-automated, reducing human intervention and making the replacement more convenient.
