the first driving mechanism is configured to control the magnetic member to move in a first direction.

5. The film removing device according to claim 4 , wherein
the first direction is perpendicular to the support surface.

6. The film removing device according to claim 4 , further comprising:
a second driving mechanism,
wherein the working table is arranged on the second driving mechanism;
the second driving mechanism is configured to control the working table to move in a second direction;
the second direction is parallel to the support surface and perpendicular to the first direction.

7. The film removing device according to claim 1 , wherein the film removing mechanism further comprises:
a buffer layer arranged on the roller and covering the electromagnetic induction coil.

8. The film removing device according to claim 1 , wherein
the magnetic region comprises an edge of the to-be-removed film.

9. The film removing device according to claim 8 , further comprising:
an adsorption mechanism provided with at least one adsorption hole in the support surface, wherein the adsorption mechanism is configured to adsorb the film structure placed onto the support surface through the adsorption hole.

10. The film removing device according to claim 9 , wherein
the adsorption mechanism further comprises:
a vacuum pumping device;
a vacuum pipe; and
a vacuum valve;

the vacuum pumping device is connected to the adsorption hole through the vacuum pipe, and configured to apply a negative pressure to the adsorption hole; and
