Intensive tempered glass surface stress gauge

Abstract

The invention belongs to the field of optical detection, and particularly relates to an intensive tempered glass surface stress gauge which comprises a worktable, an illumination unit, a light refraction unit, an imaging unit and an image processing unit. The illumination unit comprises a light source and a light source adjusting mechanism, the light source adjusting mechanism is provided with a fixing seat and an adjusting block which are arranged below the worktable, the fixing seat is arranged on the lower side of the worktable, the adjusting block is hinged to the fixing seat by a hinge pin, an adjusting threaded hole which is perforated in the up-down direction is formed in the adjusting block, an adjusting screw is arranged in the adjusting threaded hole, one end of the adjusting screw is butted onto a support block, a knob is arranged at the other end of the adjusting screw, a return spring is arranged between the fixing seat and the adjusting block, and the light source is arranged on the adjusting block. The intensive tempered glass surface stress gauge has the advantages that the light source adjusting mechanism is small in structure, accordingly, the integral structure of the stress gauge can be simplified, the integration level can be upgraded, the volume of the stress gauge can be reduced, the intensive tempered glass surface stress gauge can be further miniaturized, requirements on flexible application in the field of automatic production can be met, and the intensive tempered glass surface gauge has a broad market prospect.

Description

technical field [0001] The invention belongs to the field of optical detection, in particular to an intensive tempered glass surface stress meter. Background technique [0002] Tempered glass, also known as strengthened glass, is a kind of prestressed glass, which usually uses chemical or physical methods to form compressive stress on the surface of the glass. When the glass is subjected to external force, it first offsets the surface pressure, thereby improving the bearing capacity, so tempered glass is widely used. Used in building doors and windows, glass curtain walls, electronic instruments and other fields. However, there will be a large number of micro-cracks on the edge of tempered glass after cutting, which will reduce the strength of the glass. Especially with the vigorous development of the touch industry, the specification requirements of the touch products themselves are becoming increasingly strict. Since the touch panel uses external pressure to sense the ope...

Problems solved by technology

Although the lifting mechanism can adjust the incident angle of the light source, due to the relatively large size of the lifting mechanism, the overall structure of the strain gauge is huge, which is not conducive to the miniaturization of the strain gauge, and limits the flexible application of the strain gauge in the field of automated production

In addition, the existing strain gauge light source needs to cooperate with LED lamp beads, spotlight bowls, diffusers, and lenses to achieve the purpose of uniform light. This method has a complex structure and is limited by LED lamp beads and spotlight bowls. It is difficult to ensure that the projection spots of all equipment are consistent, which affects the accuracy and stability of the strain gauge detection
