Full-automatic surface stress gauge for secondary tempered glass

Abstract

The invention discloses a full-automatic surface stress gauge for secondary tempered glass. The full-automatic surface stress gauge comprises a gauge body, an eyepiece, a polarized industrial camera, a light source and a double-refection lens. A wide-angle lens is arranged at a position, at the front end of the polarized industrial camera, of the eyepiece, a wide-range lens focal length setting device is mounted on the wide-range lens, a positioning clamp for to-be-measured glass is arranged at a position, on the lateral side of the double-refection lens, of the upper surface of the gauge body, an automatic dripping device and a two-dimensional code marking device are mounted above the gauge body, and a laser thickness measurement device is mounted in the gauge body. The full-automatic surface stress gauge has the advantages that the gauge is high in stability and simple and convenient to operate, can measure the thickness of the glass, drip liquid and store measurement data automatically, and performs two-dimensional code marking on related measurement parameters of to-be-measured samples to facilitate quality track management.

Description

Technical field [0001] The invention relates to the technical field of glass detection, in particular to an automatic surface stress meter for secondary tempered glass. Background technique [0002] Existing glass surface stress detectors can only accurately detect primary tempered glass. At present, with the renewal of glass production technology, the emergence of secondary tempered glass is a new technological upgrade in this industry. The existing glass stress tester cannot meet the requirements of measurement accuracy and speed, and the large amount of sample data measured cannot be tracked and managed. Moreover, the light source of the existing glass surface stress tester has high energy consumption and short life span, and the emitted light wavelength is different. In line with the optimal wavelength for secondary tempered glass stress detection, the image collected by the industrial camera has too dense spacing between the detected stripes, which is not convenient for imag...

Problems solved by technology

Existing glass stress testing instruments cannot meet the requirements of measurement accuracy and speed, and a large amount of measured sample data cannot be tracked and managed. Moreover, the light source of the existing glass surface stress testing instrument has high energy consumption and short life, and the emitted light has different wavelengths. In line with the optimal wavelength for secondary tempered glass stress detection, the images collected by industrial cameras, the detected stripes are too densely spaced, which is not convenient for image recognition and judgment, and missing stripes will appear, resulting in unstable measurement and inaccurate measurement data

Moreover, the existing glass surface stress detector cannot measure the thickness of the measured glass and the thickness of the central stress layer, nor can it perform automatic dripping before detection.
