Abstract

A film peeling apparatus is provided. The film peeling apparatus comprises: a film peeling roller which is sticky; at least one peeling belt which is non-sticky; at least one first rotation shaft which is configured to drive the peeling belt to rotate, wherein when the film peeling roller rotates, the film peeling roller sticks to the film peeling belt and a release film such that the release film is peeled from an original film.

First claim

What is claimed is:

1. A film peeling apparatus, comprising:
a film peeling roller;
at least one peeling belt;
at least one first rotation shaft which is configured to drive the peeling belt to rotate,
the film peeling roller being sufficiently sticky such that when the film peeling roller rotates, the film peeling roller sticks to the film peeling belt and a release film such that the release film is peeled from an original film:
the film peeling apparatus further comprising:
at least one supporting shaft configured to allow the at least one peeling belt to rotate about the film peeling roller, the at least one first rotation shaft and the at least one supporting shaft,
wherein the at least one supporting shaft has an axis of rotation parallel to an axis of rotation of the at least one first rotation shaft;
a positioning belt and at least one second rotation shaft,
wherein the positioning belt is in contact with the peeling belt, the positioning belt and the peeling belt rotate about the at least one second rotation shaft, the at least one supporting shaft and the film peeling roller, and the positioning belt is configured to limit the movement of the at least one peeling belt in an axial direction of the at least one first rotation shaft,
wherein the at least one second rotation shaft has an axis of rotation parallel to the axis of rotation of the at least one first rotation shaft.

2. The film peeling apparatus according to claim 1 , wherein a surface of the positioning belt in contact with the peeling belt is provided with at least one groove within which the peeling belt is fixed.

3. The film peeling apparatus according to claim 1 , wherein the surface of the positioning belt in contact with the peeling belt is provided with at least one pattern which is configured to increase a frictional force between the peeling belt and the positioning belt.

4. The film peeling apparatus according to claim 1 , wherein the film peeling apparatus further comprises a recycling box, within which the at least one first rotation shaft is located,
wherein the recycling box is provided with a recycling opening which is opened in a direction in parallel to the axis of rotation of the at least one first rotation shaft, and, the recycling opening is configured such that, during rotation of the at least one first rotation shaft, the release film is brought into the recycling box by the peeling belt and falls within the recycling box.

5. The film peeling apparatus according to claim 4 , wherein the recycling box is further provided with an extracting port configured to take out the release film fallen within the recycling box.

6. The film peeling apparatus according to claim 5 , wherein the recycling box is further provided with a peeling belt exit configured to convey the at least one peeling belt out of the recycling box.

7. The film peeling apparatus according to claim 1 , wherein the at least one first rotation shaft is configured such that the at least one peeling belt is able to be wound on the first rotation shaft; and wherein the film peeling apparatus further comprises a feeding roller configured to feed the at least one peeling belt.

8. A film peeling method for a film peeling apparatus, the method comprising:
rotating a film peeling roller and a first rotation shaft;
driving at least one peeling belt to rotate by the first rotation shaft;
when the film peeling roller rotates, the film peeling roller sticks to the at least one film peeling belt and a release film by virtue of sufficiently sticky characteristics of the film peeling roller, such that the release film is peeled from an original film;
providing a supporting shaft and rotating the at least one peeling belt about the film peeling roller, the first rotation shaft and the supporting shaft,
wherein the supporting shaft has an axis of rotation parallel to an axis of rotation of the first rotation shaft;
providing a second rotation shaft and a positioning belt, the positioning belt being in contact with the peeling belt, and, rotating the positioning belt and the at least one peeling belt about the second rotation shaft, the supporting shaft and the film peeling roller, and
limiting the movement of the at least one peeling belt in an axial direction of the first rotation shaft by the positioning belt.

9. The film peeling method according to claim 8 , further comprising:
providing a recycling box;
providing the first rotation shaft within the recycling box; and
when the first rotation shaft rotates, bringing the release film into the recycling box through a recycling opening of the recycling box by the at least one peeling belt to make the release film fall within the recycling box.

10. The film peeling method according to claim 9 , further comprising:
opening an extracting port provided on the recycling box and taking out the release film fallen within the recycling box.

11. The film peeling method according to claim 10 , further comprising:
conveying the at least one peeling belt out of the recycling box from a peeling belt exit of the recycling box.
