[0037] The application will be described in detail below with reference to the accompanying drawings. Figures 1-5 Some embodiments of the application will be described in detail. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] The embodiment of the application provides a film pasting mechanism 100 arranged opposite to a workbench, wherein the workbench is used for fixing a mobile phone, and the film pasting mechanism comprises:

[0039] A film pasting device 1 is arranged opposite to the workbench, and the film pasting device 1 is in sliding connection with the mobile phone, so as to paste a film on the mobile phone.

[0040] A film tearing device 4 is arranged opposite to the edge of the mobile phone, and the film tearing device 4 comprises a clamping assembly 5, a turning assembly 6 and a transmission assembly 7 which are in transmission connection with the clamping assembly 5 respectively. The direction perpendicular to the direction from the film pasting device 1 to the mobile phone is defined as a first direction. In the first direction, the transmission assembly 7 drives the clamping assembly 5 to abut on the mobile phone with the film, so as to clamp the edge of the film body.

The beneficial effect of this design is that through the rotation of the motor driven turntable 13, the clamping assembly 5 can smoothly and accurately turn over the film body. In the traditional film tearing method, the turnover of the film body usually depends on manual operation or complex mechanical mechanism, while the design of the motor driven turnover assembly 6 of the present application greatly improves the precision and efficiency of the film body turnover process, avoiding the adverse phenomena of film body tearing or sticking. The stability and accuracy of the turnover action enable the film body to completely separate from the mobile phone screen, and reduce the risk of film body damage.
