Abstract
The utility model discloses a compact glass surface stress measuring instrument. Light emitted from an LED light source passes through a refracting prism to conduct critical emission on a sample. Part of the light source is diffused outside of a casing; and another part of the light source is reflected through a sample, passes through an imaging lens cone and is finally imaged on an image sensor. Two reflectors are also arranged inside the casing. The two reflectors are respectively arranged on light paths between the refracting prism and the imaging lens cone and between the imaging lens cone and the image sensor. After two times of reflection of a straight light path by the two reflectors, a reflective light path is formed. By adoption of the two reflectors for two times of reflection, space of a light path is minimized effectively, the structure of the instrument is more compact and smaller, and it is convenient to hold glass samples of various sizes by hands for detection.
Description
Technical field
The utility model relates to a kind of glass surface stress detector, particularly a kind of compact glass surface stress detector.
Background technology
For a long time, domestic glass production producer is due to long-term lacking detection means and the understanding to international technology, only relies on a large amount of shock resistances and fragment and tests and determine tempering processing parameter and the control to glass quality.Not only with high costs, and waste time and energy, feedback is slow, operability extreme difference, and check work often becomes a mere formality, and cannot really bulk article quality be placed under effective control.With low cost, realize quickly and easily comprehensive quality control, must adopt stress detection method to come steady production and product quality.Surface stress Dynamic Non-Destruction Measurement is conducive to stablize production and the quality of tempered glass, the more important thing is as checking semi-tempered glass quality that practicable means of testing is provided.
Glass is after bakingout process is cooling, and surface forms certain pressure conventionally, and its direction is parallel to glass surface.Because of the isotropy of glass surface pressure stresses and the mutual balance of inner tension stress and stress, cannot detect stress with the transmitted light of vertical glass planar.
The method of measuring at present surface stress can be summarized as two kinds: differential surface refraction method (Differential Surface Refractometry, be called for short DSR) and surface plunder angle polarisation method (Grazing Angle Surface Polarimetry, abbreviation GASP).
