The film peeling and coating mechanism according to claim 2, characterized in that, The rotating module includes a bearing seat connected to the bottom of the connecting plate and a rotating shaft rotatably connected in the bearing seat. The protective film stage is fixedly connected to the rotating shaft via a connecting block.

4. The film peeling and coating mechanism according to claim 1, characterized in that, The output end of the second lifting module is connected to a roller fixing seat, and the top pressure roller is rotatably connected in the roller fixing seat.

5. The film peeling and coating mechanism according to claim 4, characterized in that, The top pressure roller shaft includes a first top pressure roller shaft and a second top pressure roller shaft that are linked together. The first top pressure roller shaft and the second top pressure roller shaft are connected to each other from bottom to top in the roller shaft fixing seat.

6. The film peeling and coating mechanism according to claim 4, characterized in that, A fixed support plate is connected to the side of the connecting plate, the second lifting module is connected to the fixed support plate, and the output end of the second lifting module extends from below the fixed support plate and connects to the roller fixing seat.

7. The film peeling and coating mechanism according to claim 6, characterized in that, Multiple guide posts are slidably connected to the fixed support plate, and the multiple guide posts pass through the fixed support plate and are connected to the roller shaft fixing seat.

8. The film peeling and coating mechanism according to claim 1, characterized in that, A first bracket is connected to the support frame, and the first linear drive module is connected to the first bracket and extends from above the film coating station to above the film peeling station.

9. The film peeling and coating mechanism according to claim 1, characterized in that, The first lifting module and the second lifting module are both cylinders. An electric proportional valve is mounted on the connecting plate and is connected to the first lifting module and the second lifting module respectively.

10. The film peeling and coating mechanism according to any one of claims 1-9, characterized in that, An auxiliary platform, flush with the protective film platform, is provided on the outer side of the second end of the protective film platform.
