Abstract
An optical crystal caliper overcomes the problems of fussy operation, complex procedures and higher cost in the prior art. The crystal caliper comprises a base and a sighting telescope comprising a connecting tube, an eye lens set, a reticle, a prism set and an objective lens set, wherein the upper part of the base is fixedly connected with a digital display ruler; the head of the digital display ruler is fixedly connected with a universal joint comprising a semispherical base, a pressing piece, a connecting plate, a spherical base and a locking screw; and the sighting telescope is fixed on the universal joint. In practical measurement, an optical microscope is utilized to sight a bus on one side of a rotary cylindrical monocrystalline silicon crystal, the lens tube of the microscope is driven through the head of the digital display ruler to synchronously move, and then sights a bus on the other side of the cylindrical monocrystalline silicon crystal, therefore, the moving distance of the head of the digital display ruler is equal to the diameter of the monocrystalline silicon crystal to be measured. The optical crystal caliper has the benefits of simple structure, convenient operation and lower cost, and meets the requirement of measurement precision at the same time.
Description
Technical field
The utility model belongs to a kind of optical crystal caliper, particularly a kind of optical crystal caliper that is used for measuring the single crystal silicon diameter that rotates in the process single crystal growing furnace.
Background technology
At present, what being used for of domestic production measured that the single crystal silicon diameter that rotates in the process single crystal growing furnace adopts is the image information technology, measuring method as the disclosed a kind of pulling of crystals silicon rod diameter based on Hough transformation of CN200610105331, mainly be to adopt single camera that the image in the crystal growing process is carried out synchronous acquisition, then image information is carried out pre-service, adopt the crystal growth information in the Hough transfer pair image to detect again, obtain diameter, center of circle X coordinate and three parameters of center of circle Y coordinate, at last the parametric space curves intersection point is carried out the mean cluster operation, obtain diameter measurement value accurately.This method needs a plurality of steps, multiple devices, and complex operation, program complexity, cost are higher.
Summary of the invention
Technical problem to be solved in the utility model is to overcome prior art to need a plurality of steps, multiple devices, complex operation, program complexity, cost problem of higher, a kind of optical microscope aiming Positioning Principle of utilizing is provided, sees through the instrument that the single crystal growing furnace glass window is directly measured the single crystal silicon diameter that rotates in the single crystal growing furnace in the process.
The technical solution adopted in the utility model is:
The gun sight that the utility model includes a base and is made up of connecting cylinder, eyepiece group, graticule, prism group, objective lens, be connected with the digital display chi in the base upper fixed, the chi head of digital display chi is fixedlyed connected with the universal joint of being made up of hemisphere seat, compressing tablet, web joint and ball seat, locking nail, and described gun sight is fixed on this universal joint.
The color filter that prevents high light injury human eye in the single crystal growing furnace also is installed on the seat stand of described base.
Staple on the window boss that in use complete machine is fixed on single crystal growing furnace is housed at the base rear,, copper sheathing is installed therebetween in order to prevent the wearing and tearing of staple to base.
In actual measurement, base directly is fixed on the window boss of single crystal growing furnace, lock with locking nail, utilize a side bus of the column type single crystal silicon of optical microscope aiming rotation then, chi head by the digital display chi drives the same moved further of gun sight lens barrel, the opposite side bus of aiming column type single crystal silicon, the distance that the chi head of digital display chi moves is exactly the diameter of tested single crystal silicon.
The beneficial effects of the utility model are simple in structure, and are easy to operate, can focus according to different eyesight degree, can focus to the different operating distance.Owing to gun sight is fixed on the universal joint, therefore can carry out universal adjustment, realized measuring directly, fast the target call of the diameter of single crystal growing furnace crystal in the stove, production efficiency and the minimizing rejection rate that improves monocrystalline silicon played crucial effects.Because the utility model does not need a plurality of steps, multiple devices, thereby program is simple, cost is lower, has also satisfied the requirement of measuring accuracy simultaneously.
