[0025] It should be noted that when performing the operation of pasting the front and back protective films, first place the first protective film into the first adsorption positioning groove 110 of the first positioning jig 100, and adsorb and position the first protective film through the first adsorption positioning groove 110. Then tear off the release film layer on the first protective film, and then place the touch screen on the touch screen positioning groove so that one side of the touch screen is in contact with the first protective film, that is, the first protective film adheres to one side of the touch screen. Then place the second protective film into the second adsorption positioning groove 211 of the second positioning jig 200, and adsorb and position the second protective film through the second adsorption positioning groove 211. Then tear off the release film layer on the second protective film. Finally, buckle the first positioning jig 100 and the second positioning jig 200 with each other so that the second protective film is in contact with the other side of the touch screen, that is, the second protective film adheres to the other side of the touch screen. Then, by pressing the elastic boss 210 on the second positioning jig 200, it is ensured that the first protective film and the second protective film can be completely attached to both sides of the touch screen. It should also be noted that the first protective film can be a front protective film or a back protective film.
