Embodiment
Below, be described with reference to the preferred implementation of accompanying drawing to the percent ripple determinator of the glass plate involved by the utility model.
As shown in Figure 1, the main composition key element of the percent ripple determinator 1 of the glass plate involved by the utility model is: to the light source 2 of glass plate G irradiation light L1; Utilization is carried out projecting through the light L2 of glass plate G and shows the image display apparatus 3 of the transmission image of glass plate G; And be configured in light source 2 and image and show between apparatus 3 and the glass plate holding appliance 4 keeping glass plate G in the mode that can measure.
Light source 2 is to glass plate G irradiation light L1.Light source 2 needs to have the illumination of the degree that the transmission image of glass plate G can be projected on image described later display apparatus 3.As the illumination of light source 2, preferably use the illumination of more than such as 45000 Luxs.As light source 2, such as, can use xenon lamp, high-brightness LED, mercury lamp, fluorescent light, tungsten lamp etc.
Image display apparatus 3 shows the transmission image of glass plate G by projecting to the image of the light L2 through glass plate G.Therefore, the viewing area of the transmission image of the glass plate G of preferred image display apparatus 3 is larger than glass plate G.Image display apparatus 3 preferably uses the less concavo-convex of surface and the plate of white look.Load the image display apparatus 3 of formula shown in Fig. 1, but be not limited to this.Such as, image display apparatus 3 also can hang from not shown ceiling.In addition, image display apparatus 3 employs the component of tabular in FIG, but is not limited to this.Such as, image display apparatus 3 also can be the component of the sheets such as known roll screen.
It is also relevant with the illumination of the size of glass plate G, light source 2 that light source 2 and image show separating distance D between apparatus 3, but preference is as being 800mm ~ 1200mm.Thereby, it is possible to make the transmission image of glass plate G suitably be presented on image display apparatus 3.
Glass plate holding appliance 4 is configured in light source 2 and image shows between apparatus 3, and keeps glass plate G under the state that can measure the fluctuating of glass plate G.Glass plate holding appliance 4 is preferably configured in light source 2 and image and shows centre position between apparatus 3.In order to improve the contrast of the transmission image of the glass plate G projected to image display apparatus 3, preferably the allocation position of glass plate holding appliance 4 being configured to can to show apparatus 3 side from light source 2 and the image centre position shown between apparatus 3 to light source 2 side or image and moving.
Fig. 2 is the schematic top view of percent ripple determinator 1.
Glass plate holding appliance 4 has: the longitudinal attitude support 41 supported with longitudinal attitude glass plate G; Make the rotating part 42 that glass plate G rotates; And to the determination part 43 that the anglec of rotation (rotation amount) of rotating part 42 measures.
Glass plate G supports as longitudinal attitude by longitudinal attitude support 41.In FIG, longitudinal attitude support 41 is formed by the strip component of section in " コ " shape (section U-shaped).By inserting the bottom of glass plate G to longitudinal attitude support 41, thus the bottom of longitudinal attitude support 41 couples of glass plate G is supported.Thus, longitudinal attitude support 41 can easily support with longitudinal attitude glass plate G.
As shown in Figure 1, longitudinal attitude support 41 is not limited to the mode supported the bottom of glass plate G.Such as, by adopting the mode never illustrated for glass plate holding appliance 4 ceiling or not shown framework hung, longitudinal attitude support 41 also can support (holding) the upper end of glass plate G.In addition, the side end of all right supporting glass plate G of longitudinal attitude support 41.
Rotating part 42 makes glass plate support 41 (centered by vertical axis) rotation in the horizontal direction.Rotating part 42 rotates by making glass plate support 41, thus makes glass plate G (centered by vertical axis) rotation in the horizontal direction.Rotating part 42 is by arranging known bearing etc. and can rotating on base station 44.Rotating part 42 is disc-shape in Fig. 1, Fig. 2.In order to show the rotation amount of discoid rotating part 42, a position of the circumferential part of rotating part 42 is provided with pointer 42a.In Fig. 2 when being configured on the direction parallel with light L1, L2 by the interarea Ga of glass plate G, the pointer 42a of rotating part 42 is configured to the direction of 12 representing indication on dial plate.
Determination part 43 is fixed on the upper surface of base station 44.In Fig. 1, Fig. 2, determination part 43 is disc-shape in the same manner as rotating part 42.Determination part 43 is formed as a circle larger than rotating part 42.The peripheral part of determination part 43 is provided with scale 43a.Rotating part 42 can rotate on determination part 43.Read the position of rotation (anglec of rotation) of the pointer 42a of rotating part 42 by the scale 43a of determination part 43, the rotation amount of rotating part 42 can be measured thus.
Below, the method using the percent ripple determinator 1 involved by the utility model to measure the fluctuating of glass plate G is described.
By the groove of the bottom of glass plate G to longitudinal attitude support 41 is inserted, thus glass plate G is supported with longitudinal attitude.Then, manually make rotating part 42 rotate, thus make the interarea Ga of glass plate G parallel with light L1.Now, the scale 43a of the determination part 43 indicated by the pointer 42a of rotating part 42 is measured (in the present embodiment, 12 points of display dial indication).Then, from light source 2 towards glass plate G irradiation light L1.Now, for the image of the glass plate G shown by image display apparatus 3, only slenderly show the image of the end face of glass plate G, and do not show the transmission image of glass plate G.
Then, as shown in Figure 2, by making rotating part 42 be rotated counterclockwise, thus on image display apparatus 3, the transmission image of glass plate G is shown.Now, when glass plate G existing fluctuating, in the transmission image of glass plate G being shown in image display apparatus 3 due to this fluctuating, show longitudinal stripe pattern.
Further, when making rotating part 42 be rotated counterclockwise, longitudinal stripe pattern disappears from the transmission image of the glass plate G shown by image display apparatus 3.To stop the rotation while the disappearance confirming longitudinal stripe pattern the rotation in portion 42, and read the scale 43a indicated by pointer 42a, measure the rotation amount (anglec of rotation) that rotating part 42 has rotated thus.
The amount (height of fluctuating) of fluctuating that glass plate G exists is larger, if do not make glass plate G rotate more, then the longitudinal stripe pattern existed in the transmission image of glass plate G does not disappear.Therefore, by measuring the anglec of rotation of rotating part 42, the amount of the fluctuating that glass plate G exists can be evaluated easily.In this external the utility model, evaluate the amount of fluctuating that glass plate G exists due to the transmission image by glass plate G, therefore, it is possible to evaluate the amount of the fluctuating that the surface of glass plate G and the back side exist simultaneously.
In the above-described embodiment, the mode using the fluctuating existed in percent ripple determinator 1 couple of glass plate G to measure to the manual visual examination by operator is illustrated, but is not limited to this.Such as, also by using known CCD camera etc., the candy strip existed in the transmission image of glass plate G can automatically be taken.In addition, also can use known motor and make rotational automaticization of rotating part 42.Also determination part 43 robotization can be made by using known linear encoder etc.
Industrial applicibility
The fluctuating that the utility model can be suitable for the glass plate used in the equipment such as the flat-panel monitor such as liquid crystal display, OLED display or solar cell measures.
