As shown in figure 1, a kind of LCD friction temperatures monitoring device, for carrying out friction operation to ito glass 300, including：
Lowering or hoisting gear (not shown), rubbing device 200, support 100, infrared emittance and photodetector assembly 110, signal amplifier
With signal transacting device assembly 120, display output device 130, horizontally moving device (not shown), friction platen 400.
Support 100 is fixed on rubbing device 200, and infrared emittance is installed on support 100 with photodetector assembly 110
On, infrared emittance is connected with photodetector assembly 110 by wire with signal amplifier with signal transacting device assembly 120,
Signal amplifier is connected with signal transacting device assembly 120 by wire with display output device 130.
Rubbing device 200 has friction roller 210, and friction roller 210 is arranged with felt 220.
Horizontally moving device driving friction platen 400 moves back and forth in the horizontal direction, and ito glass 300 is positioned over rubbing table
On plate 400, lowering or hoisting gear driving rubbing device 200 vertically reciprocal lifting, to cause the felt on friction roller 210
220 closer or far from ito glass 300.
The operation principle of LCD friction temperature monitoring devices is as follows：
First it is noted that LCD friction temperature monitoring devices are by overcoming existing equipment to be rubbed using intrusion monitoring
The deficiency of intensity is wiped, using the principle that friction generates heat, directly can feed back felt and the actual frictional strength of glass, is rubbed
During work, felt and glass contact can produce heat, and glass and felt have a temperature change, and the frictional strength of felt and glass is got over
Greatly, temperature change is bigger；
Ito glass 300 is positioned on friction platen 400；
By lowering or hoisting gear drive rubbing device 200 vertically, with cause the felt 220 on friction roller 210 with
Suitable position contacts with ito glass 300, and in the present embodiment, lowering or hoisting gear is motor lead screw driving structure；
Rubbing device 200 works, and driving friction roller 210 rotates, to cause felt 220 to be rubbed with ito glass 300
Wipe, meanwhile, horizontally moving device driving friction platen 400 moves in the horizontal direction, to cause the whole panel of ito glass 300
By the felt 220 on friction roller 210, in the present embodiment, horizontally moving device is cylinder driving structure；
It is friction roller 210 that the infrared light supply and directional bearing of infrared emittance and photodetector assembly 110, which are harmonized,
On felt 220 separated with ito glass 300 after region, the position of detection for felt and 2 near glass contact points of tangency to
3cm region, by signal amplifier and signal transacting device assembly 120 and display output device 130 by the hair on friction roller 210
The temperature value of cloth 220 is shown, the infra-red radiation of infrared emittance is modulated into alternation radiation, is changed into by photodetector
Corresponding electric signal, by amplifier and signal processor, the electric signal measured is changed into the temperature change of measured target
Value, is shown on display output device 130；
Display output device 130 has warning function, when detect temperature change value it is too small or excessive when, illustrate frictional strength
In the presence of exception, prompt functions are triggered.
During work, friction roller 210, which pushes, to change, the felt 220 on friction roller 210 and ito glass 300
Frictional strength changes, and caused heat also can be different, and it is also different to show temperature change, now, infrared emittance
The temperature information collected with photodetector assembly 110 can be showed timely, be easy to monitoring in real time actual raw
Frictional strength during production.In the present embodiment, the quantity of infrared emittance and photodetector assembly 110 is three groups, three groups infrared
Generator is intervally arranged and is installed on support 100 successively with photodetector assembly 110 in " one " font.Filled on support 100
Infrared emittance and photodetector assembly 110 with 2 to 3 groups or so, can further monitor frictional strength in practice
Distribution, the information of acquisition frictional strength uniformity that can be stable.
LCD friction temperatures monitoring device of the present utility model, monitoring felt contact front and rear temperature change with glass friction
Difference, to determine the frictional strength of reality.The mechanical amesdial commonly used with industry monitors LCD rubbing machine roller intrusion or height
The monitoring method contrast of degree, the amesdial that LCD rubbing machines are equipped with can only monitor, measure the height change of friction roller, belong to
The action at mechanical position monitors, and the contact condition after friction roller stickup friction cloth with ito glass can be variant, felt deformation quantity
Changing always, the degree of the change does not interfere with the mechanical height of LCD friction rollers, i.e., the pressure that LCD rubbing machines are equipped with
The friction cloth Frotteurism actual with ito glass can not accurately be measured by entering amount or roller height monitor mode.This practicality is new
The LCD friction temperatures monitoring device of type uses the principle of infrared measurement of temperature, the state that direct measurement, monitoring felt contact with ITO, leads to
Heat and temperature difference caused by crossing friction, are changed into the contrast difference of frictional strength, can more accurately monitor Frotteurism
Change.
The change that distinguishable ± 0.1 DEG C of temperature monitoring apparatus of the present utility model, rubbing for diverse location can be monitored simultaneously
Wipe the situation of uniformity, the mechanical height monitor mode of script of arranging in pairs or groups adjusts LCD rubbing machines, makes LCD friction process more stable,
Improve LCD display quality.
LCD friction temperatures monitoring device of the present utility model, by setting falling unit, rubbing device 200, support 100, red
Outer generator and photodetector assembly 110, signal amplifier and signal transacting device assembly 120, display output device 130, level
Mobile device, friction platen 400, and setting is optimized to each structure, it directly can feed back felt when rubbing and producing
With glass is actual contacts situation.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
