The full-automatic abbe refractometer is high in measurement accuracy, high in degree of automation, simple in structure and low in cost; the popularization and application in the market can be facilitated; the full-automatic abbe refractometer can be used for achieving the purposes of making breakthrough on the basis of the advanced technology at home and abroad, exceeding the level of foreign, completing independent development and promoting the improvement of the strength of China in the detection field.
Description
Technical field
Full-automatic Abbe refractometer belongs to an optical gauge, is specifically related to a kind of Abbe refracting means.
Background technology
Refractive index is the important parameter of characterized medium optical property, and spectroscopy and other important category can be explained and be applied to research refractive index.In food inspection technical field, by measuring the refractive index of food liquid, can differentiate the composition of food, determine the concentration of food, and then pure degree and the quality of judgement food; As measure the pol that refractive index can be determined the food such as the concentration of liquid glucose and beverage, sweet can, can also measure and take the content of soluble solid of the food such as fruit juice that sugar is principal ingredient, honey; And for example utilize the different rule of different fatty acid refractive indexes, by measuring grease refractive index, determine the kind of fatty acid in grease, and then composition and the quality of judgement grease.Except food inspection technical field, refractometry is also applied in multiple industries such as spectacles industry, jewelry industries.
Refractive index detects and relies on apparatus for measuring refractive index, and Abbe refractometer is exactly wherein.Through investigation, traditional Abbe refractometer passes through manual operations completely, and needs user to carry out recorded matter refractive index value in the mode of range estimation, and this metering system, not only can bring the error causing due to subjective factor into, and complex operation step, inefficiency.Along with the popularization of computer technology and the development of digital technology, some novel digital refractometers have been there are, these digitizing refractometers are compared with traditional Abbe refractometer, automaticity and measuring accuracy are all improved, but complicated optical texture, make the cost of these digitizing refractometers high, also restricting their promotion and application on market.
Utility model content
In order to address the above problem, the utility model has designed a kind of full-automatic Abbe refractometer, and not only measuring accuracy is high for this full-automatic Abbe refractometer, and automaticity is high, and simple in structure, with low cost, is conducive to carry out promotion and application on market.
The purpose of this utility model is achieved in that
A full-automatic Abbe refractometer, comprises housing, the first outer sleeve, trim ring, the second outer sleeve, CCD upper plate, CCD lower shoe, lens combination and refracting prisms group;
On the first described outer sleeve, have the diaphragm for preventing that unnecessary veiling glare from passing through, between the first outer sleeve and lens combination, by three dog screws, be fixedly connected with;
The between centers of described lens combination by and the second outer sleeve between clearance fit locate;
Described trim ring is with flange, and the outside of flange is connected with the second outer sleeve end inside thread;
Described CCD upper plate radially has the straight trough matching with the flange of trim ring, and trim ring is to-and-fro movement in straight trough;
Between described CCD upper plate and the second outer sleeve, by helicitic texture, be connected, CCD upper plate is realized and being moved along straight trough direction by rotating the second outer sleeve;
Described CCD lower shoe has U-shaped hole, and CCD lower shoe connects CCD upper plate by four bolts;
Described line array CCD sticks on CCD lower shoe.
Beneficial effect: the full-automatic Abbe refractometer of the utility model, not only measuring accuracy is high, and automaticity is high, and simple in structure, with low cost, is conducive to carry out promotion and application on market.

On the first described outer sleeve 2, have the diaphragm for preventing that unnecessary veiling glare from passing through, between the first outer sleeve 2 and lens combination 7, by three dog screws, be fixedly connected with;
The between centers of described lens combination 7 by and the second outer sleeve 4 between clearance fit locate;
Described trim ring 3 is with flange, and the outside of flange is connected with the second outer sleeve 4 end inside threads;
Described CCD upper plate 5 radially has the straight trough matching with the flange of trim ring 3, trim ring 3 to-and-fro movement in straight trough;
Between described CCD upper plate 5 and the second outer sleeve 4, by helicitic texture, be connected, CCD upper plate 5 is realized and being moved along straight trough direction by rotating the second outer sleeve 4, and this technical characterictic is for regulating the distance between line array CCD and the exit facet of lens combination 7;
Described CCD lower shoe 6 has U-shaped hole, and CCD lower shoe 6 connects CCD upper plate 5 by four bolts, and this technical characterictic is for regulating the angle of inclination of line array CCD;
Described line array CCD sticks on CCD lower shoe 6, and CCD upper plate 5 moves along straight trough direction, can drive the line array CCD rectilinear motion sticking on CCD lower shoe 6, guarantees that the photosurface of line array CCD is adjusted under constant angle.
