Technical field
This utility model is related to the detection technique in glass production, relates generally to a kind of Thickness sensitivity dress of plate glass
Put.
Background technology
Float glass is presently most effective high quality flat glass production mode.In order to improve the production of float glass
Efficiency, needs the formative stage in glass that the monitoring of real-time continuous is carried out to technological parameters such as thickness of glass.Particularly in production
When line changes the production thickness of glass, the monitoring of thickness of glass is even more important.Transformation process inevitably produces underproof
Glass and bring loss, the size of loss realizes the time length of process depending on conversion.In traditional thickness of glass monitoring side
Under formula.Thickness of glass measurement is carried out in the cold end of production line.The glass forming operation that carries out in the hot junction of production line and in cold end
Time delay between carried out acquisition information operation is exactly that glass tape moves to the time of cold end from shaping area.This time is big
Summary spends more than 30 minutes.If before thickness of glass measurement is moved to annealing furnace, thickness will be greatly reduced and regulated and controled
Time required for journey, reduce the loss for producing that off-grade glass is brought.
Floatation glass production line hot junction thickness measure at present mainly adopts the optical mode of triangle.The optical mode of triangle will
Collimated beam irradiates glass surface at an angle, realizes glass by the lateral shift of measurement glass upper and lower surface the reflected beams
The measurement of glass thickness.Triangle optical mode needs closely to be placed on measuring probe in glass surface high-temperature area, probe
Comprising the thermo-responsive photoelectric device such as laser instrument and CCD, it is therefore necessary to take cooling and high temperature protection measure.Triangle optical measurement side
Formula can be heated by air and caused index disturbance is affected, it is necessary to take relative complex corrective action.And pop one's head in
Distance apart from glass surface is relatively fixed, and probe is laid and debugging facility is complex.Float glass is for new survey
The demand of amount technology becomes clear day by day.
Utility model content
The purpose of this utility model there are provided a kind of thickness detection apparatus of new plate glass, for reducing thickness
Time required for regulation process, and using simple and easy.
This utility model realizes that the technical scheme that purpose is adopted is：A kind of thickness detection apparatus of plate glass mainly include

Put in housing, length scanning infrared optical fiber laser instrument is passed through by linking optical cable and optical fiber collimator connection, photodetector
Link optical cable and optical fiber collimator connection；The housing upper is provided with slide bar, and the upper end of slide bar is arranged in orbit, in track
Motor, motor and slide bar connection are provided with, are moved by the controllable slide bar of motor in orbit.
Using a kind of thickness detecting method of plate glass of above-mentioned detection device, realize that step is as follows：
A：Glass thickness measuring detection means is arranged on above glass tape hot junction, based on fiber Fabry-Perot tunable optic filter
Length scanning optical fiber laser output laser injection fibre, laser is irradiated to by optical fiber collimator for the surface of glass；
B：The upper and lower surface of glass reflection laser is interfered respectively, constitutes optics Fabry sieve Fabry-Parot interferent instrument,
Reflected light again passes by optical fiber collimator, is coupled into optical fiber, is detected by detector；
C：By the interference light signal of synchronizing detection glass upper and lower surface reflection wavelength scanning laser, can obtain on glass
Interference spectrum of the fabry perot interferometer that lower surface is constituted in the range of scanning wavelength；
D：Interference spectrum is processed by the photodetector in device, the letter of the physical thickness of glass can be accurately obtained
Breath.
The glass that this utility model is caused in cold-end glass thickness measure in shortening the method for existing glass measurement thickness
The time delay of thickness regulation process.While for improving in existing hot junction thickness measure mode due to by air heating
The impact of caused index disturbance must take relative complex corrective action, and pop one's head in laying and debugging facility are more multiple
Miscellaneous not convenient property.Only need to launch every time on-line measurement by Ray Of Light using the detection means and method described in utility model
Sheet thickness, measurement are more facilitated, and shorten the time delay of original technology.
