Example 1

As shown in fig. 1 to 6, the measuring jig for the cover glass 7 comprises the cover glass 7, a gypsum layer 6 and a cushion block 5, wherein the cushion block 5 can be an aluminum block, and the aluminum block, the gypsum layer 6 and the cover glass 7 are sequentially stacked from bottom to top. The gypsum layer 6 is fixed to the upper surface of the aluminum block. To ensure the accuracy of measurement, the upper surface of the gypsum layer 6 is ground and polished to be smooth and flat, and the thickness of the gypsum layer 6 is uniform. The upper surface of the gypsum layer 6 is parallel to the upper surface of the aluminum block and perfectly fits the cover glass 7. The gypsum layer 6 has loose texture and smooth surface, so that the glass can not be scratched after being placed, and meanwhile, the measurement accuracy can not be influenced by external factors, namely, wrinkles can not appear at the through holes, so that the measurement result is inaccurate. The measuring jig divides the measuring jig into: the probe motion track area 1, the positioning area 2 and the placing area 3 are arranged on the outermost ring of the upper surface of the top of the measuring jig, and the probe motion track area 1 is in a strip shape; the positioning area 2 is closely connected with the probe motion track area 1, and the positioning area 2 is positioned at the highest end of the outer side edge of the measuring jig; the placing area 3 is positioned in the middle of the measuring jig. The probe motion track area 1 is in a strip shape at the outermost ring of the upper surface of the jig. Based on the precision requirement of cover plate glass measurement, the diameter of a probe which is usually selected does not exceed 5mm, so that a certain gap is reserved between the probe and a probe motion track area 1 on a jig, the depth of the area is required to be larger than 5mm, the phenomenon that the depth is insufficient is avoided, the center of a coordinate axis is not overlapped with the center of the probe during measurement, and measurement data are inaccurate. The definition of the probe motion track area is suitable for initial probe walking, a measurement datum line (namely, a coordinate axis) is determined, and after the actual probe determines the datum, the probe can determine the size of the measurement glass and the profile degree of each position. The positioning area 2 is higher than other functional areas and is also positioned at the highest end of the jig. The positioning area 2 is next to the probe motion track area 1. The corner vertex of the positioning area 2 is a positioning point 21 of the probe, and the positioning point 21 is arranged on the measuring jig. The existence of the locating point 21 can effectively provide location for the origin of measurement, the locating point 21 can be used for locating a probe, the distance measurement of the light holes 31 is facilitated, and then the size and the profile of the glass can be obtained through calculation. This measurement method belongs to the prior art and is therefore not described in detail. The shape and structure of the placement area 3 are similar to those of the cover glass 7. The corner vertex of the positioning area 2 is the positioning point 21 of the probe. The placing area 3 occupies the largest area of the upper surface of the jig and is used for placing the cover glass 7. The shape and structure of the placement area 3 are similar to those of the cover glass 7.

In some embodiments, wall empty slots 4 are arranged in the middle of the placement area 3, the positioning area 2 and the probe motion track area 1, and wall empty holes 41 are arranged at the corners of the wall empty slots 4. The wall empty groove 4 and the wall empty hole 41 are arranged on the measuring jig, and the wall empty groove 4 and the wall empty hole 41 can protect the edge corners of glass and avoid the line edges and corners of the positioning points 21 from being bumped, so that the glass is damaged. The wall empty groove 4 and the clearance hole are used for avoiding collision of corners of the cover plate glass 7 when the cover plate glass 7 is placed in the placing area 3, and are also beneficial to processing of the placing area 3 of the grinding head processing jig. The measuring jig can be fixed by adopting modes such as magnetic attraction and bolts.

Example two

The manufacturing method of the measuring jig of the cover plate glass 7 comprises the following steps: 1A) Processing the cushion block 5 into a proper structural size; 1) Placing a proper amount of gypsum powder into a container, adding water to prepare a solution with consistent particle distribution, wherein the mass ratio of the water to the gypsum powder is as follows: 0.6 to 0.65:1; 2A) The periphery of the cushion block 5 is surrounded, and a gap is not reserved between the surrounded material and the cushion block 5; 2) Pouring gypsum liquid on the upper surface of the cushion block 5; 3) After the gypsum liquid is cooled and molded, the gypsum layer 6 is processed to be consistent in thickness, and the surface is smooth and flat; 4) Placing the cushion block 5 fixed with the gypsum layer 6 into a measuring jig, and placing cover glass 7 on the surface of the gypsum layer 6; 5) If the gypsum layer 6 is scratched after use, the gypsum layer 6 is subjected to secondary processing to remove the surface scratches.

In some embodiments, in order to prevent the gypsum liquid from flowing everywhere after pouring on the aluminum block, the periphery of the jig can be surrounded, and no gap exists between the surrounded material and the jig, so that the gypsum liquid is ensured to be solidified on the upper surface of the aluminum block of the jig, and the gypsum liquid can be enabled to have a certain thickness after solidification. The thickness may be set to 2 to 5mm. The upper surface of the jig is coated with gypsum, so that the softness of the contact surface is increased, the scratch is reduced, and the measurement result is not influenced;

in some embodiments, if the surface of the gypsum layer 6 is scratched accidentally, the surface can be reprocessed into a smooth and flat surface by grinding and polishing, the surface scratch is removed, the gypsum layer is reused, and the cost is reduced; meanwhile, more processing time and processing cost are saved.

Example III

The jig assembly for protecting the cover plate glass 7 during measurement comprises a gypsum layer 6 and a cushion block 5, wherein the cushion block 5 and the gypsum layer 6 are sequentially stacked from bottom to top. The existing cover glass is directly placed on the cushion block, and the surface of the cushion block is easy to scratch the surface of the cover glass, so that when the cover glass is used, teflon or a protective film can be attached to the contact surface where the cover glass is placed. However, when the profile degree of the teflon and the protective film is measured, folds can appear at the through holes, so that the measurement result is inaccurate. The upper surface of the jig is coated with gypsum, the gypsum layer is loose in texture and smooth in surface, and the softness of the contact surface is increased, so that glass can not be scratched after being placed, and meanwhile, wrinkles can not appear at the through holes, so that the measurement result is inaccurate.

Example IV

The manufacturing method of the jig assembly for protecting the cover plate glass 7 during measurement comprises the following steps: 1) Placing a proper amount of gypsum powder into a container, adding water, and preparing into a solution with consistent particle distribution; 2) Pouring gypsum liquid on the upper surface of the cushion block 5; 3) After the gypsum liquid is cooled and molded, the gypsum layer 6 is processed to be uniform in thickness.

Thus, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concepts of the present disclosure, some details known in the art are not described. How to implement the solutions disclosed herein will be fully apparent to those skilled in the art from the above description.
