y2, turning over the polycarbonate plate and the PET film, performing UV exposure on the polycarbonate plate upwards, and setting the exposure energy to 100-500mj/cm 2 Pre-curing;
y3, separating the polycarbonate plate from the PET film, wherein the thickness of the obtained UV adhesive is the texture thickness;
y4, cleaning uncured UV glue by using a UV glue cleaning process;
y5, curing by UV mercury lamp with curing energy of 500-600mj/cm 2 The conveying speed is 4-6m/min, and the cycle times are 20-30 times;
y6, arranging a protective film layer on the surface of the polycarbonate plate;
y7, using a laser process to radium-cut a second positioning hole on the surface of the polycarbonate plate, wherein the circle center of the second positioning hole and the circle center of the first positioning hole are positioned at the same position, the diameter of the second positioning hole is larger than that of the first positioning hole, and the radium-cutting power is set to be 50W, and the cutting speed is set to be 20mm/min;
and Y8, attaching a reinforcing sheet on the surface of the second positioning hole.
11. The glass texture mold laminated structure according to claim 10, wherein the UV gel cleaning process of step Y4 comprises cleaning UV gel using a UV gel cleaning agent having a temperature of 31-35 ℃, the UV gel cleaning agent comprising alcohol: acetone=6: 4, wherein the alcohol concentration is 99%.
12. The glass texture mold stack and the method for manufacturing the same according to claim 10, wherein the protective film layer of step Y6 is provided by covering a protective film on the surface of a polycarbonate plate.
13. The glass texture mold stack and method of making the same according to claim 10, wherein the protective film layer arrangement of step Y6 comprises direct transfer of PET film using a mold.
14. The glass textured mold laminate structure of claim 1, wherein the fabrication of the anti-smudge layer comprises electroplating at least one anti-fingerprint film layer having a thickness of 20-40nm on the textured layer surface.
