A kind of sheet glass belongs to physical field at the line sweep measurer for thickness, and relating to a kind of is the metering outfit of feature to adopt the isotope particle radiation, is used to measure thickness, partly is made up of pick-up unit, mechanical driving device and control and treatment device etc.
Whether the thickness of sheet glass evenly reaches the quality that the requirement that whether meets production specification directly affects the glass finished product.At present, because the width of sheet glass reached about 3 meters, and existing thickness measuring mode is just carried out one-point measurement at certain position of glass plate, can not comprehensively and objectively reflect the actual (real) thickness parameter of glass plate, can not provide reliable controlled variable for production control.Therefore need and to carry out horizontal multi-point scanning thickness measuring to glass plate.Actual (real) thickness parameter with the reflection glass plate, if adopt ray that conventional at present radioactive isotope power supply launches or the X ray that excites target to produce to pass Strength Changes behind the glass and the thickness of material has this principle of certain quantitative relationship to measure the multiple spot thickness of sheet glass, consideration for measuring accuracy, requirement is arranged in glass-board surface, and the detector and the isotope source of both sides keep high level of synchronization in the scanning survey process up and down, just need design and produce high precision, large span, the on-the-spot rugged surroundings of adaptation and durable O type scanning support, this difficult technically realization.If make isotope source and detector be positioned at a side of sheet glass, and traverse measurement synchronously, measuring accuracy is guaranteed.The purpose of this utility model is to solve online transversal scanning multiple spot thickness measure problem in the sheet glass production.
Pick-up unit of the present utility model is by water inlet 24 and the water delivering orifice 23 of measuring dolly 1, isotope source 2, shielding carrying shield 3, carrying shield supporting cylinder 4, cooling jacket 22, cooling jacket 22, detecting device 25 compositions such as grade, isotope source 2 wherein adopts low energy γ photon isotope source
241Am.Shielding carrying shield shell is a heat-resisting steel, and interior is plumbous cover, and shielding carrying shield 3 is enclosed within the outside of isotope source 2, to prevent invalid harm ray.Carrying shield supporting cylinder 4 is fixed on isotope source 2 and shielding carrying shield 3 and measures on the dolly 1, and the angle theta that cooling jacket 22 and carrying shield supporting cylinder are 4 is adjustable between 10 °～40 °.Mechanical driving device is measured operation guide rail 7, transversal scanning frame 8, correction standard specimen frame 9, the transmission gear 12 and 17 of dolly 1 by the bogie wheel 6 and 21 of adjustable for height measurement dolly 1, and chain 13 compositions such as grade are in transmission connection.Wherein the width of transversal scanning frame 8 is 400mm, and span is 4000mm, and horizontal positioned supplies the utility model to carry out the dressing plate glass of using from normal moveout correction on the correction standard specimen frame 9.Be in transmission connection chain 13 and transmission gear 12 and 17 tight interlocks, and link to each other with measurement dolly 1, can drive it and on transversal scanning frame 8, move.The control and treatment device is made up of non-contact switch 5, travel switch 10, travel switch 11, travel switch 19, travel switch 20, servo-actuated stube cable 14, microcomputer secondary instrument 15, speed reduction unit 16, driving motor 18 etc.Wherein microcomputer secondary instrument 15 is made up of input-output unit 26, microcomputer 27, keyboard 28, display 29, pen recorder 30 etc.
Detection principle of the present utility model is: the gamma-rays that isotope source 2 sends projects on the running sheet glass vertically downward, utilizes the thickness of gamma-ray intensity of backscattering and scatterer sheet glass to have certain quantitative relationship to measure the thickness of sheet glass.Backscattering line by tested sheet glass reverse reflex arrives the scintillator NaI(T1 in the detecting device 25) on the crystal, this NaI(T1) the interior photomultiplier close-coupled of crystal and detecting device 25 is together.Beat on the photocathode of photomultiplier by the photon that scintillator is converted to, photon is got electronics from photocathode, electronics is gone to anode by negative electrode through each dynode in the formed electric field of photomultiplier high pressure, thereby formation electric current, this electric current converts electric impulse signal in the photomultiplier load, by servo-actuated stube cable 14 input microcomputer secondary instruments 15, and send into microcomputer 27 through input-output unit 26 and handle, the one-tenth-value thickness 1/10 of the treated tested sheet glass that obtains provides by display 29 and pen recorder 30.
During the utility model work, under the control of microcomputer 27 through driving motor 18, speed reduction unit 16, transmission gear 17 and 12 and the effect of the chain 13 that is in transmission connection, measurement dolly 1 is moved on transversal scanning frame 8, measure dolly 1 mobile be that bogie wheel 6 and 21 by adjustable for height measurement dolly 1 rolls on the operation guide rail 7 of measuring dolly 1 and realizes that along with moving back and forth of measurement dolly 1, the utility model carries out at the line sweep thickness measuring.During on-line measurement, under the control of microcomputer 27, measuring dolly 1 moves between travel switch 20 and non-contact switch 5, realization is to the scanning thickness measuring of sheet glass, under the control of microcomputer 27, realize measuring the top that dolly 1 regularly moved and rested on the correction standard specimen frame 9 that is placed with normal glass by checking non-contact switch 5 and travel switch 10 states, carry out from normal moveout correction, measure the sheet glass top that dolly 1 returns actual measurement automatically after correction finishes, restart on-line automatic round scanning survey.
During the utility model work, under the control of microcomputer 27, can be by the state of checking travel switch 11 and 19 to measuring out-of-limit warning of scanning of dolly 1.The utility model also has the alert function of the disconnected blackboard newspaper of glass by the processing of microcomputer 27.One-point measurement is carried out in the optional position above measurement dolly 1 also can rest on tested sheet glass under the control of microcomputer 27.
Initialization state of the present utility model is provided with by keyboard 29.
For make detecting device 25 can be under the hot environment of measure field operate as normal, be surrounded by cooling jacket 22 in the outside of detecting device 25, water inlet 24 and water delivering orifice 23 are arranged on it, and the ringing by chilled water makes detecting device 25 to adapt to be lower than 600 ℃ high-temperature work environment.
