[0028] Specifically, the length of the sensor glass block 7 is longer than that of the cover plate block 8, so that the longer sensor glass block 7 can be used to position the sensor glass body 9, and the shorter cover plate block 8 can be used to position the PMMA cover plate body 10.

[0034] Specifically, the air suction device is not shown and can be an air suction pump. By starting the air suction pump and through the connection between the air intake pipe port 5 and the air suction hole 4, the sensor glass body 9 can be well stabilized by using the cross air suction groove 3 and the air suction hole 4.

[0035] Please refer to Figures 2-5, in this embodiment, it further includes a sensor glass main body 9 and a PMMA cover plate main body 10. A sensor glass FPC 901 is arranged on one side of the sensor glass main body 9; the size of the sensor glass main body 9 is adapted to the area between the eight sensor glass clamping blocks 7, and the sensor glass main body 9 is positioned and clamped between the eight sensor glass clamping blocks 7; the size of the PMMA cover plate main body 10 is adapted to the area between the eight cover plate clamping blocks 8, and the PMMA cover plate main body 10 is positioned and clamped between the eight cover plate clamping blocks 8.

Start the suction device, and the gas in the cross suction groove 3 converges at the suction hole 4 for suction to fix and position the sensor glass main body 9;

[0039] Then peel off the protective film on the back of the PMMA cover plate main body 10, clean the back of the PMMA cover plate main body 10, and at the same time peel off the OCA release film of the sensor glass main body 9 on the jig body 1.
