Abstract

A film attaching apparatus for attaching a film to an object including a curved surface, including a support member having the object on an upper portion thereof; a belt member spaced apart from the support member upwardly and having a lower surface to which the film adheres and an upper surface having a first friction reducing layer; and an adherer spaced apart from the belt member upwardly and moving along an outer surface of the object to apply a pressure to the belt member so as to make the belt member adhere to the object on the support member.

First claim

What is claimed is:

1 . A film attaching apparatus for attaching a film to an object including a curved surface, comprising:
a support member having the object on an upper portion thereof; a belt member spaced apart from the support member upwardly and having a lower surface to which the film adheres and an upper surface having a first friction reducing layer; and an adherer spaced apart from the belt member upwardly and moving along an outer surface of the object to apply a pressure to the belt member so as to make the belt member adhere to the object on the support member.

2 . The film attaching apparatus as claimed in claim 1 , wherein the adherer includes:
a body part having an inner space; a pressed part adhering to the belt member and at one portion of the body part so that at least one portion of the pressed part is exposed outside the body part; a first slip part having a band shape, the first slip part to be slid along an end of the pressed part adhering to the belt member; a supply part to supply the first slip part to the pressed part; and a winding part to wind with the first slip part slid along the pressed part.

3 . The film attaching apparatus as claimed in claim 2 , wherein the adherer further includes a second friction reducing layer on at least one surface of the first slip part.

4 . The film attaching apparatus as claimed in claim 1 , wherein the adherer includes:
a body part having an inner space; a pressed part adhering to the belt member and at one portion of the body part so that at least one portion of the pressed part is exposed outside the body part; a second slip part having a band shape of a closed curved line, the second slip part to be slid along an end of the pressed part adhering to the belt member; and a rotating part to supply the second slip part slid along the pressed part to the pressed part.

5 . The film attaching apparatus as claimed in claim 4 , wherein the adherer further includes a third friction reducing layer on at least one surface of the second slip part.

6 . The film attaching apparatus as claimed in claim 2 , wherein the end of the pressed part adhering to the belt member is rounded.

7 . The film attaching apparatus as claimed in claim 2 , wherein a radius of the end of the pressed part ranges from 1 mm to 5 mm.

8 . The film attaching apparatus as claimed in claim 1 , wherein the first friction reducing layer includes fluororesin or silicone.

9 . The film attaching apparatus as claimed in claim 1 , wherein the belt member includes metal.

10 . The film attaching apparatus as claimed in claim 9 , wherein the belt member includes stainless steel.

11 . The film attaching apparatus as claimed in claim 1 , wherein a thickness of the belt member ranges from 20 μm to 200 μm.

12 . The film attaching apparatus as claimed in claim 1 , further comprising a driver coupled with the adherer to move the adherer in multiple directions.

13 . The film attaching apparatus as claimed in claim 12 , further comprising a rotator having a first portion coupled with the driver and a second portion rotatably coupled with the adherer.

14 . The film attaching apparatus as claimed in claim 13 , further comprising a controller to control rotation of the rotator so that the adherer is in a vertical state to a virtual tangential line of the curved surface of the object.
