The diamond fixer includes diamond suction bar and vacuum pump, diamond suction bar is fixed on suction bar support frame on the two-dimensional moving platform, the tail portion of diamond suction bar is connected with vacuum pump, and its front end is equipped with diamont suction head, and said two-dimensional moving platform is positioned on the observation platform of microscope.
Description
A kind of method and device that the jewel cut is detected of the present invention, the especially method and apparatus that every size of processing the back jewel is accurately measured.
The evaluation of diamond, popular in the world is the classification of 4C quality, promptly to color, weight, the inside and outside feature of diamond with cut is measured, classification.Wherein, the measurement of cut is very important.The difficulty of measuring is bigger.
The round diamond of standard has 57 (58) individual facets, requires physical dimension, angle and the ratio of cutting grinding stone are accurately measured, and its quality is made evaluation.External existing two quasi-instruments: a class is carried out labor measurement with engineer's scale to the projection image of diamond, calculates that the operation of measuring is numerous and diverse, efficient is lower, practicality is relatively poor.This quasi-instrument is mainly diamond ratio projector, the diamond proportion grading device of roughly the same GIA (Gemological InstituteAmerica) manufacturing, Belgian HRD diamondscope.Another kind of is fully-automatic diamond ratio measuring instrument, with the laser scanning diamond, or carries out Flame Image Process with high precision stylus photography back, and this quasi-instrument can be measured the cut receipt of diamond quickly and automatically.But the price height, and can not observe the inside and outside feature of diamond simultaneously.This quasi-instrument has U.S. GIA product B rilliant Eye and Sarim Dim-port, Belgian Sarin Dia-Mension.
Still based on 10 times of magnifier visual estimations, the vernier caliper that is equipped with the 0.02mm precision goes out according to probation report to the detection of diamond cutter at present most gemstone testings center.Along with the continuous expansion of diamond sales volume in recent years, people are also more and more higher to the requirement of diamond cutter, but the means of identifying still rest on original level, and not only the speed of Jian Ceing is slow, and the precision of detection also is affected.
Purpose of the present invention just provides a kind of inside and outside feature of energy fast detecting diamond, measures the diamond cutter intelligent detecting method and the device of processed diamond cutter fast.
Diamond cutter intelligent detecting method of the present invention is to adopt each wedge angle point-to-point measurement mnemonics of diamond to detect, its concrete method is to write down the point coordinate of each wedge angle of diamond, calculate distance and angle between the each point by signal processing apparatus then, last each size of determining diamond automatically.Diamond cutter intelligent detection device of the present invention is made up of diamond fixed part and signal detecting part branch, this device mainly is made up of microscope, two-dimentional mobile platform, diamond fixator, signal processing apparatus, the diamond fixator comprises diamond soup stick and vacuum pump, the diamond soup stick is fixed on the soup stick support on the two-dimentional mobile platform, the afterbody of diamond soup stick is connected with vacuum pump, be provided with the diamond suction nozzle in the front portion of diamond soup stick, two-dimentional mobile platform is positioned on the microscopical observation platform.The two dimension mobile platform is that the linear slide adjusting mechanism of two relative vertical movements is directions X micro-adjusting mechanism and Y directional trim mechanism, and being respectively equipped with a displacement transducer on this two adjusting mechanism is directions X displacement transducer and Y direction displacement transducer.Displacement transducer adopts capacitive displacement transducer, and the output terminal of sensor is connected with signal processing apparatus respectively.
The plane of symmetry with diamond during detection is projected on the microscope ocular focal plane, imagine this planar graph and place a plane right-angle coordinate, and each cusp in the figure (A, B, C, D, E, F, G) if coordinate position can measure, corresponding each line segment and angle can be obtained by the mathematical computations of signal processing apparatus in this figure so.
The invention has the advantages that:
A. this method efficiency of measurement is higher, and with the PC logotype, to each point sampling time＜3 second, each plane of symmetry Measuring Time about 1-3 minute, each diamond was measured about about 10 minutes, measure convenient, speed is fast, precision is higher.
B. fitting on the gemolite of this device both can be surveyed diamond cutter, can observe inside, the surface of diamond again and calculate the weight of jewel, had multiple function.
C. cheap more abroad with quasi-instrument rate of exchange lattice, meet users' requirement.
Fig. 1 is a concrete structure synoptic diagram of the present invention.Microscope 1, two-dimentional mobile platform 2, diamond fixator 3, signal processor 4 are wherein arranged, straight vacuum pump 32.
Fig. 2 is the main TV structure synoptic diagram of the present invention's two dimension mobile platform, and soup stick support 21, directions X fine setting machinery 22, Y directional trim machinery 23, directions X displacement transducer 221, Y direction displacement transducer 231, diamond fixator 3, diamond soup stick 31, diamond suction nozzle 311 are wherein arranged.
Fig. 3 is a left TV structure synoptic diagram of removing diamond fixator 3 among Fig. 2.
Fig. 4 is the backplan of Fig. 2.
Fig. 5 is the contour structures synoptic diagram of diamond, and diamond cusp A, B, C, D, E, F, G are arranged among the figure.
Embodiment of the present invention are as follows:
Structurally the jewel soup stick is installed in X, and on the transportable two-dimentional mobile platform of Y direction, mobile platform is the dovetail location, the screw rod moving structure, and the mobile range of X, Y direction is ± 10mm.The dovetail of attachable mechanical stage and the fixed grid of capacitor grid transducer link.The fixed grid of capacitor grid transducer and moving grid cooperate and require the gap to beat little and parallel with dovetail face.When mobile platform moved, its displacement signal can be exported from sensor interface.Deliver to signal processor, handle by single-chip microcomputer (PC).Its method is to adopt each cusp point-to-point measurement mnemonics of diamond to detect, and promptly specifically writes down the coordinate of each wedge angle of diamond, calculates distance and angle between the each point, last each size of determining diamond automatically by signal processing apparatus then.
During use, jewel is adsorbed on the diamond suction nozzle, rotates jewel, make the desktop of diamond and kite face perpendicular to surface level, this face is a plane of symmetry of diamond, requires each size, angle on this plane of symmetry are measured.Projection is brightness, the beam size adjustable size of illumination down, and the silhouette border of diamond is clearly projected on the microscopical eyepiece focal plane.Regulate microscopical object lens position, make the cross-graduation in image and the eyepiece clear equally.
The A point that moves among the A that two-dimentional mobile platform makes center of reticule and diamond is aimed at, press the correspondent button of computing machine, (X, Y) the coordinate collection that is about to this point finishes, and respectively the B among the figure, C, D, E, F, a G point pointwise is sampled with quadrat method, and the coordinate position that is about to each point is determined.
With the distance of point-to-point in the plane analytic geometry, put the distance of straight line, the angle formula of straight line and straight line for the basis, set up a mathematical model, can obtain each size, angle, ratio on this plane of symmetry.
