System for manufacturing display unit
Provided is a system for manufacturing a display unit, the system including: a carrying unit which carries an optical film including a polarizing film including an adhesive layer and a release film to which the polarizing film is bonded to be peeled off through the adhesive layer; a cutting unit which cuts the optical film by a predetermined depth, in which the release film is not cut, and forms a polarizing film sheet piece on the optical film; a peeling unit which peels the polarizing film sheet piece from the release film; and an attachment unit which attaches the polarizing film sheet piece peeled from the release film to a panel, in which the attachment unit includes: a pair of attachment rolls which presses and attaches the polarizing film sheet piece onto one surface of the panel; and a magnetic force generating unit or a suction part, which suppresses an upper attachment roll positioned at an upper side between the pair of attachment rolls from sagging by using magnetic force or suction.
1. A system for manufacturing a display unit, which attaches an optical film to a panel, the system comprising:
a carrying unit which carries the optical film including a polarizing film;
a cutting unit which cuts the optical film to a size corresponding to a size of the panel; and
an attachment unit which attaches the optical film to the panel,
wherein the attachment unit includes:
an attachment roll which presses and attaches the optical film onto one surface of the panel; and
a sagging suppressing unit which suppresses the attachment roll from sagging.
2. The system of claim 1 , wherein the sagging suppressing unit includes a magnetic force generating unit which suppresses the attachment roll from sagging by using magnetic force.
3. The system of claim 2 , wherein the magnetic force generating unit includes a permanent magnet having an intensity of 20 to 50 MGOe.
4. The system of claim 2 , wherein the magnetic force generating unit includes an electromagnet, of which magnetic force is adjusted by adjusting an amount of an applied current.
5. The system of claim 2 , wherein the magnetic force generating unit includes a plurality of magnetic force generating units which are disposed while being spaced apart from one another in a longitudinal direction of the attachment roll.
6. The system of claim 1 , wherein the sagging suppressing unit includes a support part which is in contact with a part of an outer peripheral surface of the attachment roll and supports the attachment roll.
7. The system of claim 2 , wherein the sagging suppressing unit adjusts a distance between the magnetic force generating unit and the attachment roll.
8. The system of claim 1 , wherein a diameter of the attachment roll is 20 to 80 mm.
9. The system of claim 1 , wherein a length of the attachment roll is 1,800 to 3,700 mm.
10. The system of claim 2 , wherein the magnetic force generating unit is in contact with a part of an outer peripheral surface of the attachment roll and is in the form of a roll which is capable of supporting the attachment roll.
11. The system of claim 2 , wherein the attachment roll includes a ferromagnetic substance at a position facing the magnetic force generating unit.
12. The system of claim 1 , wherein the sagging suppressing unit directs suction toward the attachment roll and suppresses the attachment roll from sagging by using suction force.
