Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described specific embodiment is merely to illustrate and explains this utility model, is not limited to this utility model.
In this utility model, in the case where contrary explanation is not made, the noun of locality such as " upper and lower " for using typically refers to phase
Answer accompanying drawing page upper and lower.
As shown in Fig. 1, Fig. 3, Fig. 4, a kind of sag measurement apparatus of glass substrate that this utility model is provided, including mutual
The first bracing frame 1 be arrangeding in parallel and the second bracing frame 2, the first bracing frame 1 are identical with 2 structure of the second bracing frame, can be
String configuration of the cross section in I-shaped or rectangle, for material-saving and the own wt of mitigation bracing frame, this reality
In new, it is I-shaped string configuration preferentially to select cross section, and here, the first bracing frame 1 and the second bracing frame 2 are used for
Glass substrate 3 is supported, in order to ensure the accuracy of 3 sag of glass substrate measurement, can be in the first bracing frame 1 and the second bracing frame
Support plate 4 in the middle of arranging between 2, middle support plate 4 can be arranged in the middle of the first bracing frame 1 and the second bracing frame 2 with equally spaced.And
And, middle support plate 4 has:First working condition, supports glass substrate 3 to make its holding level, and the second working condition, away from glass
Substrate 3 make wherein subordinate hang down, here, it should be noted that " away from glass substrate 3 " will in the middle of support plate 4 shift onto towards side,
So that the middle part of glass substrate 3 is sagging, after glass substrate 3 is stable, measure in 3 liang of sides of the state lower glass substrate
Between minimum point and four angle peaks amount to height of six points apart from platform, to calculate the sag value of glass substrate.In Fig. 4
H2, H1 and H3 represent the middle minimum point of glass substrate both sides and four angle peak measured values respectively.By above-mentioned technical side
Case, arranges middle support plate between two bracing frames arranged in parallel, makes glass substrate that there is level by middle support plate
Two kinds of working conditions sagging with middle part, to complete the measurement of glass substrate sag.On the one hand, the measurement apparatus simple structure, makes
With convenient, low cost;On the other hand, the measuring method of the measurement apparatus is simple to operate, ensure that glass substrate sag is measured
Accuracy and reliability.
Specifically, as depicted in figs. 1 and 2, middle support plate 4 is string configuration, and the string configuration includes basic portion 41
With supporting part 42, the cross section of basic portion 41 is rectangle, and the cross section of supporting part 42 is isosceles triangle, also, the isosceles three
Angular drift angle can be formed as arcuate structure.Thus it is possible, on the one hand, supporting glass substrate 3 to make its holding level in middle support plate 4
During, arc structure can be steadily contacted with the surface of glass substrate 3, reduced stress concentration, can be avoided in glass base
3 surface of plate leaves cut;On the other hand, during middle support plate 4 is pushed over towards side, the arc structure can be avoided
To scratching the surface of glass substrate 3, so as to affect product quality.
Further, as shown in figure 1, the width that can be highly more than middle support plate 4 of middle support plate 4, so, in glass
In the middle part of substrate 3 sagging during, can prevent glass substrate 3 from touching middle support plate 4, so as to affect 3 sag of glass substrate
The accuracy of measurement.
In addition, in this utility model, as shown in Fig. 2 the sag measurement apparatus of glass substrate are also included for positioning the
The location-plate 5 of one bracing frame 1, middle support plate 4 and the second bracing frame 2, location-plate 5 can be rectangular slab, the length of the rectangular slab
Be formed with three open slots 51 on side, three open slots 51 respectively with the first bracing frame 1, middle support plate 4, the second bracing frame 2
Grafting coordinates.Here, it should be noted that when glass substrate size is larger, accordingly, it is desirable to adjust the first bracing frame 1, in
Between spacing between support plate 4 and the second bracing frame 2, the location-plate of other sizes at this moment, can be changed, to ensure on location-plate
Open slot and the first bracing frame 1, middle support plate 4,2 grafting of the second bracing frame coordinate.In addition, location-plate 5 can be plugged on
One bracing frame 1, middle support plate 4, the upper surface of the second gripper shoe 2, it is also possible to be plugged on the first bracing frame 1, middle support plate 4, with
And second gripper shoe 2 side, and 5 pairs of the first bracing frames 1 of multiple location-plates, middle support plate 4, second can also be used to support
Plate 2 is positioned, to ensure the accuracy of sag measurement, in position this utility model of the quantity of location-plate 4 and grafting not
Do concrete restriction.
In this utility model, the first bracing frame 1, the second bracing frame 2 and location-plate 5 can be aluminum alloy material, adopt
On the one hand aluminum alloy material is easily worked, and on the other hand can mitigate bracing frame own wt;By middle support plate towards side
During pushing over, between middle support plate and glass substrate, there is frictional force, therefore middle support plate can be made up of antistatic material,
The middle support plate that antistatic material is made can reduce the low voltage electrostatic for carrying in process of production, so as to by middle support plate 4
The process that pushes over is prevented due to triboelectrification and damages glass substrate.
As shown in Figure 3, Figure 4, in this utility model, using the measurement apparatus to glass substrate sag measurement can according to
Lower step is carried out:
The first step:First bracing frame 1, the second bracing frame 2 and middle support plate 4 are equally spaced positioned on platform 6;
Second step:It is plugged on the first bracing frame 1, the second bracing frame 2 and middle support plate 4 using location-plate 5, so as to by the
One bracing frame 1, the second bracing frame 2 and middle support plate 4 are equally spaced positioned on platform 6;
3rd step:Remove location-plate 5;
4th step:Glass substrate 3 is placed horizontally on the first bracing frame 1, middle support plate 4 and the second bracing frame 2;
5th step:Middle support plate 4 is pushed over towards side;
6th step:Middle minimum point H1 of 3 liang of sides of measurement glass substrate, four angles peak H2 and H3 amount to six points
Apart from the height of platform 6, the altimeter according to measurement result and the first bracing frame 1 calculates sag value.
