Description

The glass surface measuring stress instrument
[technical field]
The utility model relates to stress monitoring equipment, relates in particular to a kind of glass surface measuring stress instrument.
[background technology]
Existing glass surface tension gauge is manually to estimate by the micrometer eyepiece counter stress, calculates stress value according to formula then.Individual viewpoint and cognitive to the individual who detects is depended in the detection of this mode entirely, so its check result has bigger subjective factor.And the common sodium lamp of the shadow of existing glass surface tension gauge employing, energy consumption is big, the life-span is short, and the wavelength of light of being sent does not meet the optimal wavelength that stress glass detects.
[utility model content]
The utility model provides a kind of glass surface measuring stress instrument at the above-mentioned defective of prior art, with the precision of raising stress detection, and improves detection efficiency.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of glass surface measuring stress instrument comprises a Computing system, an imaging lens barrel, a lens barrel angular adjustment bearing, a host platform, a main frame casing, a light source, a birefringent prism; Described lens barrel angular adjustment bearing and main frame casing are fixed on the host platform; Described imaging lens barrel is located on the lens barrel angular adjustment bearing, and described imaging lens barrel one end is positioned on the light refraction direction of described birefringent prism, and the other end is provided with an industrial camera; Described birefringent prism partly protrudes from the mainframe box surface, and described light source is located in the main frame casing, and the light that birefringent prism is positioned at light source penetrates on the direction; Described Computing system is connected with described industrial camera.
Preferably, described light source is a led light source.
Preferably, be provided with polarizer and quarter wave plate between described light source and the birefringent prism successively.
Preferably, be provided with analyser, quarter wave plate, optical filtering box between described imaging lens barrel and the birefringent prism successively.
Preferably, be provided with the light source crane in the described main frame casing, described light source crane is in transmission connection with the light source lift adjustment handwheel that part is protruded the main frame casing, and described led light source is fixed on the light source crane.
As can be seen from the above technical solutions, the utility model is by Computing system reading of data, and the data error that reads is little, is convenient to the management of measurement data simultaneously.The utility model also adopts led light source, reaches 10000 hours serviceable life, and the wavelength that emits beam is near testing wavelength recently.
