Description
Technical field
The present invention relates to vacuum glass tightness online test method and device.
Background technology
Vacuum glass is that two sheet glass surroundings are sealed, and its gap is evacuated, and owing to being vacuum between two sheet glass, so the performance such as heat insulation, the noise control of vacuum glass is fine.The sealing quality of vacuum glass directly affects the vacuum tightness in vacuum glass, bad if vacuum glass seals in process of production, will cause the vacuum tightness of vacuum glass to reduce, and makes vacuum glass lose due effect, and can't use.Detecting at present vacuum glass tightness can be all generally to adopt heat flow method to be detected, judge sealing although can accurately detect the thermal insulation of vacuum glass, but because detection time is long and required checkout equipment complexity, it is only suitable for testing laboratory test and can't meets the continuous detecting of vacuum glass in enormous quantities, is unsuitable for using on the vacuum glass production line.
Summary of the invention
The problem existed for prior art, the object of the present invention is to provide a kind of detection speed fast, and detection method is simple, is suitable for the vacuum glass tightness energy Rough Inspection method of using on the vacuum glass production line.
For achieving the above object, vacuum glass in-line detection method for vacuum level of the present invention, concrete steps are: 1) set up vacuum glass vacuum tightness level threshold value; 2) adopt a side of the infrared light supply local irradiation vacuum glass to be measured of fixed wave length, at the vacuum glass opposite side, by sensor sensing glass, the temperature rise in setting-up time changes; 3) the temperature rise result of variations detected according to sensor and level threshold value relatively, judge whether the sealing property of vacuum glass meets standard.
Further, the wavelength of described infrared light supply is medium wave, and its wavelength coverage is 1.5-6 μ m.
Further, the step that detects the temperature rise variation is specially: after infrared light supply irradiates, record the temperature now recorded, stop vacuum glass being irradiated, record the temperature now recorded after waiting for certain hour, the temperature rise that the temperature difference of two temperatures is in setting-up time changes, and wherein setting-up time can be adjusted as required.
Vacuum glass vacuum tightness on-line measuring device of the present invention, comprise infrared heater, sensor and computing machine, and described infrared heater is for applying the infrared light supply of fixed wave length to vacuum glass one side to be measured; Described sensor setting, at vacuum glass opposite side to be measured, for detection of the temperature signal of vacuum glass to be measured, and is passed to described computing machine by this temperature signal; The temperature rise that described computing machine is calculated vacuum glass for the thermometer recorded according to sensor changes, and temperature rise is changed with the vacuum tightness level threshold value of its storage and compares, and judges whether the sealing property of vacuum glass meets standard.
Further, the fixed wave length that described infrared heater applies is medium wave, and its wavelength coverage is 1.5-6 μ m.
Further, also be connected with warning device on described computing machine, if the vacuum tightness of computing machine judgement vacuum glass does not meet standard, control warning device and give the alarm.
The time that vacuum glass in-line detection method for vacuum level of the present invention detects is short, and detection method is simple, can meet vacuum glass quantity-produced demand in enormous quantities, is suitable for using on production line.In addition, the required equipment of detection method of the present invention is simple, cheap, can reduce to a certain extent the production cost of vacuum glass.
The accompanying drawing explanation
The structural representation that Fig. 1 is pick-up unit of the present invention.
Embodiment
Below in conjunction with accompanying drawing, vacuum glass tightness on-line measuring device of the present invention is described:
As shown in Figure 1, vacuum glass tightness on-line measuring device of the present invention, comprise infrared heater 2, sensor 3 and computing machine 4, infrared heater 2 is for applying the infrared light supply of fixed wave length to vacuum glass 1 one sides, the wavelength of this infrared light supply is medium wave, and wavelength coverage is 1.5-6 μ m, and sensor 3 is arranged on vacuum glass 1 opposite side, for detection of the temperature signal of vacuum glass 1, and this temperature signal is passed to computing machine 4; The temperature of computing machine 4 for recording according to sensor 3, the temperature rise that calculates vacuum glass 1 changes, and temperature rise is changed with the vacuum tightness level threshold value of its storage and compares, and judges whether the vacuum tightness of vacuum glass 1 meets standard.In order to show more intuitively that whether surveyed vacuum glass is qualified, also be connected with the warning device (not shown) on computing machine 4, if the vacuum tightness of computing machine judgement vacuum glass does not meet standard, control warning device and give the alarm.
Vacuum glass tightness online test method of the present invention, concrete steps are: model vacuum glass temperature rise level threshold value is as the comparing data of estimating sealing property; 2) adopt a side of the infrared light supply local irradiation vacuum glass to be measured of fixed wave length, at the vacuum glass opposite side, by sensor sensing glass, the temperature rise in setting-up time changes; 3) the temperature rise result of variations detected according to sensor and level threshold value relatively, judge whether the vacuum tightness of vacuum glass meets standard, if the temperature rise result of variations that sensor detects is less than level threshold value, prove that the intact product of vacuum glass sealing-in is qualified; Otherwise the vacuum glass sealing-in is defective, need to separate Reseal.
Change and need to successively record the vacuum glass temperature that sensor records for twice if want to detect temperature rise, then calculate.Enumerated a kind of mode that temperature rise changes that detects in the present embodiment: infrared light supply irradiated vacuum glass after 4 minutes, the temperature that record now records.Stop vacuum glass being irradiated, then wait for 4 minutes and record the temperature now recorded, the temperature rise that the temperature difference of two temperatures is in setting-up time changes.
Qualified vacuum glass can be recorded to a temperature rise according to the method described above and change, this temperature rise changes as the temperature rise level threshold value.Requirement difference according to vacuum glass to specification product, the temperature rise level threshold value can correspondingly change.Infrared light supply irradiation time and the stand-by period that stops irradiating not are only to be limited as 4 minutes, can adjust accordingly according to demand yet.
The time of test method needs more than 1 hour that conventional heat flow method detects glass K value just can detect vacuum glass whether encapsulate intact, and detection method of the present invention with about 10 minutes just can bigness scale to go out product qualified, be adapted at using on production line.
It is to be noted and any distortion of making according to the specific embodiment of the present invention all do not break away from the scope that spirit of the present invention and claim are put down in writing.
