[0022] In order to make the purpose, technical content and effects of the utility model clearer, the following will be described in detail in combination with the embodiments and the drawings.

[0023] Please refer to Figure 1 and Figure 2 , the utility model discloses a cover plate profile degree measuring jig, including profiled support table 1 and measuring assembly 2;The support surface of profiled support table 1 along the contour edge of itself is provided with a plurality of avoiding openings 11, and the measuring assembly 2 includes first measuring gauge 21, and the first measuring gauge 21 has the measuring probe that enters avoiding opening 11 from the side wall of profiled support table 1.

[0024] Working principle: The glass cover plate 4 is supported by the profiling support table 1, and a plurality of avoiding openings 11 are arranged on the support surface of the profiling support table 1 along the contour edge of the profiling support table 1, and the measuring probe of the first measuring table 21 can effectively contact the edge of the glass cover plate 4 through the avoiding opening 11, so as to accurately quantify and record the profile value of the edge of the glass cover plate 4.

[0025] Preferably, the first measuring table 21 and the second measuring table 22 are dial gauges or micrometers.

[0026] Please refer to Figure 3 Further, the profiling support table 1 is provided with a positioning column 12.

[0027] As can be seen from the above description, the positioning column 12 can quickly complete the positioning of the glass cover plate 4 on the profiling support table 1.

[0028] Further, the profiling support table 1 is provided with a positioning column 12.

[0029] Please refer to Figure 2 Further, the distance from the edge of the support surface of the profiling support table 1 to the edge of the cover plate standard area is A, and A is 5mm to 15mm. Preferably, A is 10mm.

[0030] As can be seen from the above description, by subtracting the value A from the amount of the measuring probe of the first measuring table 21 extending into the avoiding opening 11, the difference between the glass cover plate 4 and the ideal glass cover plate 4 shape defined by the cover plate standard area can be obtained.

[0031] Please refer to Figure 1 and Figure 2 Further, the profiling support table 1 is provided with a positioning column 12.

[0032] As can be seen from the above description, the positioning column 12 can quickly complete the positioning of the glass cover plate 4 on the profiling support table 1.

[0033] Further, the positioning column 12 is detachably arranged on the profiling support table 1.

[0034] As can be seen from the above description, the positioning column 12 is detachably arranged, so that the positioning column 12 can be replaced to ensure the positioning accuracy of the glass cover plate 4 on the profiling support table 1. At the same time, the positioning column 12 can be removed when necessary, and the surface profile of the glass cover plate 4 can be measured at the positioning column 12.

[0035] Please refer to Figure 1 Further, the support surface of the profiling support table 1 has a profiling positioning groove 13.

[0036] As described above, the accessories on the glass cover plate 4 are fixed through the profiling positioning groove 13, which can ensure the stability of the glass cover plate 4 on the profiling support table 1.
