Description

Technical Field

[0001] The utility model belongs to the technical field of glass detection, and in particular relates to a device for detecting internal stress of a glass plate. Background Art

[0002] The detection of internal stress of glass sheets is an important step to ensure the quality and performance of glass. The internal stress of glass directly affects its strength. Problems such as thermal cracking and impact cracking are often related to excessive internal stress. Therefore, accurate detection of internal stress of glass sheets is crucial to prevent these problems and ensure the safety and reliability of glass products.

[0003] There are many methods for detecting the internal stress of glass. Among them, the optical detection method is widely used because of its non-contact, fast speed, high precision, and non-destructive to the test sample. The principle of the optical detection method is to measure and analyze the internal stress of glass based on optical phenomena such as light interference, scattering, and birefringence. These methods measure the characteristic changes of light propagating in glass, such as optical path difference, refractive index change, etc., and indirectly infer the internal stress distribution of glass through the obtained light data. However, the optical detection method has high requirements on the cleanliness of the glass surface. Foreign matter and marks on the glass surface may cause errors in the detection results. In the process of industrial production of glass plates, the finished glass plates may leave foreign matter or marks on the surface of the glass plates due to long movement or storage time on the assembly line. Since the glass plate itself is transparent, it is not easy to completely detect the marks on its surface with the naked eye, and it is laborious to manually clean each glass plate to be tested, which is not conducive to improving production efficiency and reducing labor intensity. Therefore, we propose a glass plate internal stress detection device. Utility Model Content

[0022] The glass plate 7 to be tested is erected and placed between the symmetrical clamping plates 62. The cylinder 61 is driven to push the clamping plates 62 to move the clamping plates 62 toward the direction of the glass plate 7 to be tested until the clamping plates 62 on both sides completely clamp the glass plate 7 to be tested to fix the glass plate 7 to be tested on the device. The motor 21 is started, and the motor 21 drives the threaded rod 22 to rotate.
