Abstract

A cloth attachment device includes a frame, and further includes: a first roller arranged on the frame and capable of being rotated around its axis relative to the frame; a transmission mechanism arranged on the frame and capable of being moved relative to the frame, a to-be-attached cloth being arranged between the first roller and the transmission mechanism, two opposite surfaces of the to-be-attached cloth being in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and a driving mechanism configured to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable, through the transmission mechanism, the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.

First claim

What is claimed is:

1. A cloth attachment device, comprising a frame, wherein the cloth attachment device further comprises:
a first roller arranged on the frame and capable of being rotated around its axis relative to the frame;
a transmission mechanism arranged on the frame and capable of being moved relative to the frame, a to-be-attached cloth being arranged between the first roller and the transmission mechanism, two opposite surfaces of the to-be-attached cloth being in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and
a driving mechanism configured to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable, through the transmission mechanism, the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller,
the transmission mechanism comprising a second roller capable of being rotated around its axis relative to the frame, the axis of the second roller being parallel to the axis of the first roller, and the to-be-attached cloth being arranged between the first roller and the second roller and parallel to the axes of the first roller and the second roller,
a plurality of first positions being arranged on the first roller and at a first straight line, a plurality of second positions being arranged on the second roller and at a second straight line, and the first straight line and the second straight line both being parallel to the axes of the first roller and the second roller, and
wherein a distance between the first straight line and the second straight line is less than a thickness of the to-be-attached cloth, and a difference between the thickness of the to-be-attached cloth and the distance is 1 mm to 2 mm.

2. The cloth attachment device according to claim 1 , wherein the frame comprises a horizontally-disposed table, the to-be-attached cloth is arranged on the table, and the first roller is arranged above the table and the second roller is arranged below the table.

3. The cloth attachment device according to claim 1 , wherein an outer layer of the second roller is covered with a rubber material.

4. The cloth attachment device according to claim 1 , wherein when the first roller and the second roller are driven by the driving mechanism to rotate in opposite directions, the to-be-attached cloth between the first roller and the transmission mechanism is curled up around the first roller.

5. The cloth attachment device according to claim 4 , wherein the first roller and the second roller are rotated at an identical rate.

6. The cloth attachment device according to claim 1 , wherein the first roller is of a diameter identical to the second roller.

7. The cloth attachment device according to claim 1 , wherein the to-be-attached cloth is a double-sided adhesive tape comprising cover layers arranged at upper and lower surfaces, and an adhesive layer arranged between the cover layers, and the cover layer of the double-sided adhesive tape facing the first roller is peeled off.

8. The cloth attachment device according to claim 1 , wherein the to-be-attached cloth is a rubbing cloth, and an outer surface of the first roller is covered with a double-sided adhesive tape with its cover layer being peeled off.

9. The cloth attachment device according to claim 1 , wherein the driving mechanism comprises a servo motor.

10. The cloth attachment device according to claim 1 , wherein the frame comprises:
a vertically-disposed gantry frame; and
a clamping mechanism secured onto the gantry frame and configured to secure the first roller onto the gantry frame.

11. The cloth attachment device according to claim 1 , wherein the second roller is secured onto the frame through a rolling bearing.

12. The cloth attachment device according to claim 1 , wherein the frame comprises a horizontally-disposed table, the transmission mechanism comprises a transportation body arranged on the table and capable of being translated relative to a surface of the table, the transportation body is of a planar surface, the to-be-attached cloth is laid on the transportation body, and the first roller is arranged above the transportation body.

13. A cloth attachment method using the cloth attachment device according to claim 1 , comprising steps of:
arranging a to-be-attached cloth between a first roller and a transmission mechanism;
adjusting a gap between the first roller and the transmission mechanism in such a manner than edges of the to-be-attached cloth at two opposite surfaces are in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and
enabling a driving mechanism to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.

14. The cloth attachment method according to claim 13 , wherein the to-be-attached cloth is a double-sided adhesive tape, and prior to the step of arranging the to-be-attached cloth between the first roller and the transmission mechanism, the method further comprises:
peeling off a cover layer of the double-sided adhesive tape facing the first roller.

15. The cloth attachment method according to claim 13 , wherein the to-be-attached cloth is a rubbing cloth, and prior to the step of arranging the to-be-attached cloth between the first roller and the transmission mechanism, the method further comprises:
attaching a double-sided adhesive tape onto the first roller, and peeling off a cover layer arranged at an outer layer of the double-sided adhesive tape attached onto the first roller.

16. The cloth attachment method according to claim 13 , wherein the transmission mechanism comprises a second roller capable of being rotated around its axis relative to the frame, the axis of the second roller is parallel to the axis of the first roller, and the to-be-attached cloth is arranged between the first roller and the second roller and parallel to the axes of the first roller and the second roller,
wherein the cloth attachment method further comprises:
when the first roller and the second roller are driven by the driving mechanism to rotate in opposite directions, enabling the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.
