The rotating frame 4 is connected to the top of the operating platform 1 and is located on the inner side of the fixed frame 3. The winding shaft 5 and the unwinding shaft 6 are respectively installed between the two fixed frames 3 and are located at the same position as the rotating frame 4, the rotating wheel 9 is rotatably connected between the two rotating frames 4, one end of the rotating wheel 9 is connected to a driving motor 10 installed on the rotating frame 4, one end of the winding shaft 5 is connected to a winding motor 11 installed on the fixed frame 3, a film roll 12 is installed on the unwinding shaft 6, one end of the film 16 on the film roll 12 is connected to the winding shaft 5 by passing through the tensioning roller 7 and the guide roller 8, an arc-shaped pressing plate 13 is fixedly connected to the outer side of the rotating wheel 9, an arc-shaped cutting knife 14 is fixedly connected to the outer side of the arc-shaped pressing plate 13, a spring 15 is connected between the tensioning roller 7 and the fixed frame 3, and a mounting groove 17 is installed on the top of the conveying mechanism 2.

[0027] Through the setting of the operating platform 1 and the conveying mechanism 2, the mobile phone touch screen is placed in the installation groove 17 located on the conveying mechanism 2 for conveying, the driving motor 10 drives the rotating wheel 9 to rotate synchronously, and the winding motor 11 drives the winding shaft 5 to wind synchronously. When the right edge of the mobile phone touch screen is transported to the bottom of the rotating wheel 9, the arc cutter 14 on the right side of the arc pressure plate 13 cuts the film 16, and the arc pressure plate 13 presses the film 16 on the surface of the mobile phone touch screen, and continues to move synchronously. The arc pressure plate 13 continues to press the film 16 on the surface of the mobile phone touch screen, and the arc cutters 14 on the front and rear sides of the arc pressure plate 13 cut the film 16 on the front and rear sides of the mobile phone touch screen. 6. After the pasting is completed, the arc cutter 14 on the left side of the arc pressure plate 13 cuts the film 16 on the left side of the mobile phone touch screen, and the mobile phone touch screen can be detached at this time.

[0039] Step 3: After the pasting is completed, the arc-shaped cutter 14 on the left side of the arc-shaped pressing plate 13 cuts the film 16 on the left side of the mobile phone touch screen. At this time, the mobile phone touch screen with the film is separated and transported away by the conveying mechanism 2.

[0040] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
