Background technology
The online measuring thickness device that is applied to liquid crystal glass base requires to measure the glass substrate that thickness is 0.3mm to 1mm, and precision reaches ± 1 μ m.Simultaneously, require measuring thickness device not only can eliminate the influence that glass swinging causes measuring accuracy, and can eliminate the influence that glass deformation causes measuring accuracy to a certain extent.
And that the technology that is used for the transparent substance non-contact thickness measuring in the market mainly contains is following several:
1. ultrasonic thickness test method, this method is used ultrasonic measurement, and precision is the millimeter level.
2. laser triangulation, full accuracy can reach ± 0.4 μ m.But under this accuracy requirement, range too little (± 1mm).Use this technology to do online measurement, be difficult to offset the influence of aspects such as glass swinging, warpage, vibrations, physical construction error.In the practical application, be difficult to realize the precision of ± 0.4 μ m.
3. interferometric method, this method utilize the optical interference principle to measure, and precision can reach nanoscale.But the range of this method is very little, can not satisfy the requirement of glass thickness measuring.
To sum up, what prior art was applicable to glass thickness measuring on the liquid-crystalline glasses production line only has a laser triangulation, and its precision is generally per mille to ten thousand/three.But it is very high and could realize on the stabilised platform very much that this precision need be positioned over glass flatnesses such as marble platform, and require glass not have deformation such as warpage.As be applied to the glass vertical lifting, when not having the situation of online measurements such as platform, this method can't realize high-acruracy survey.When having warpage, swing etc. to influence as glass, precision can be poorer.
The utility model content
The purpose of this utility model just is to provide a kind of liquid crystal glass base measuring thickness device, and it not only can eliminate the influence that glass swinging causes measuring accuracy, and can eliminate the influence that glass deformation causes measuring accuracy to a certain extent.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model is made of glass substrate grip unit and the rectilinear motion test cell that is arranged on glass substrate grip unit one side; The glass substrate grip unit comprises: frame, be installed on the position adjusting mechanism on the frame, on position adjusting mechanism, be equipped with Pneumatic component, Pneumatic component possesses a barometric control unit, be equipped with the clamping limb that is driven by Pneumatic component on the Pneumatic component, clamping limb is provided with the clamping strip of softwood matter; The rectilinear motion test cell comprises: by guide rail slide block pair, the synchronous rectilinear motion unit that constitutes of band, be assemblied on the rectilinear motion unit can before and after the slide unit of adjusting position, be assemblied in the thickness measurement sensor on the slide unit.
Pneumatic component described in the utility model is the gas pawl, and its barometric control unit comprises through gas circuit successively by compression air road: valve, filtrator reduction valve, reversal valve, throttling valve, gas pawl; Reversal valve is for can control the pressurized air direction, and then the solenoid valve of control gas pawl switching.
The beneficial effects of the utility model are: this device of the utility model possesses this glass clamping device of a kind of glass clamping device can clamp glass in thickness measuring, not only can the fixing glass position, eliminate the influence of glass swinging to the thickness measuring precision; Simultaneously, clamp system applies suitable holding force to glass, also can eliminate the influence of a part of glass deformation to the thickness measuring precision.Thickness measurement sensor is by a rectilinear motion unit drives moving linearly.Thickness measurement sensor is measured thickness of glass in real time in the straight-line while, can obtain one group of thickness data on direction of glass after moving into.These data can obtain the thickness curve of glass behind over-fitting.The utility model uses pneumatic element, as moving components such as gas pawls, drives two clamping limbs.When glass did not enter measuring thickness device, Pneumatic component was opened clamping limb.When glass entered measuring thickness device, Pneumatic component drove the clamping limb action, clamps glass.Clamp behind the glass promptly can fixing glass the position, eliminate the influence of glass swinging to the thickness measuring precision; Simultaneously, clamp system also can be eliminated the influence of glass deformation to the thickness measuring precision with there being the glass folder of deformation flat.Pneumatic component described in the utility model possesses a barometric control unit, can regulate supply gas pressure so that clamping force is suitable.Suitable standard is: make have the glass of deformation straight when making clamping limb clamp glass as far as possible, but be unlikely to destroy glass.Pneumatic element also possesses an apparatus for adjusting position simultaneously, and the standard of adjusting is: when clamp arm clamps glass, make glass be in the optimum measurement district of sensor apart from the distance of thickness measurement sensor.Rational in infrastructure its of the utility model not only can be eliminated the influence that glass swinging causes measuring accuracy in a word, and can eliminate the influence that glass deformation causes measuring accuracy to a certain extent.
