and a groove portion formed in a shape corresponding to the protrusion and configured to press the protrusion. 4. The method of claim 3,
The outer circumferential surface of the body portion and the flat portion have lengths corresponding to each other, the laminating apparatus. 4. The method of claim 3,
The protrusion is
a first protrusion; and
and a second protrusion spaced apart from the first protrusion. 6. The method of claim 5,
The first protrusion and the second protrusion are formed in the same shape as each other,
A distance between the first protrusion and the second protrusion corresponds to a length of an outer circumferential surface of the body portion, the laminating apparatus. 6. The method of claim 5,
The first protrusion and the second protrusion are formed in different shapes,
The groove portion,
a first groove formed in a shape corresponding to the first protrusion; and
and a second groove spaced apart from the first groove and formed in a shape corresponding to the second protrusion,
A distance between the first protrusion and the second protrusion corresponds to a length of an outer circumferential surface of the body part disposed between the first groove part and the second groove part, the laminating apparatus. 4. The method of claim 3,
The roller is
The laminating apparatus further comprising: a protrusion formed in a shape corresponding to the channel and configured to adhere the film to the inner surface of the substrate forming the channel by pressing the film while being inserted into the channel. 4. The method of claim 3,
The protrusion and the groove portion are formed in a tapered structure in which the size of the inner diameter is gradually decreased along the axial direction, the laminating apparatus. 4. The method of claim 3,
a temporary bonding unit configured to temporarily adhere one end of the film to the substrate;
a cutting unit having one end configured to cut the film temporarily attached to the substrate to a length corresponding to the substrate;
a transfer unit configured to bring the film into contact with the roller while transferring the substrate in one direction;
a sensing unit configured to detect the protrusion formed on the substrate; and
The laminating apparatus further comprising a roll driving unit configured to elevate and rotate the roller. a first roller configured to adhere a film to the first planar portion and the at least one first protrusion while moving along one surface of the substrate including a first flat portion and at least one first protrusion; and
and a second roller configured to adhere a film to the second flat portion and the at least one second protrusion while moving along the other surface of the substrate including the second flat portion and the at least one second protrusion. Device. 12. The method of claim 11,
The first roller is
a first body portion configured to press the first flat portion; and
at least one first groove formed in a shape corresponding to the at least one first protrusion and configured to press the at least one first protrusion;
The second roller is
a second body portion configured to press the second flat portion; and
and at least one second groove formed in a shape corresponding to the at least one second protrusion and configured to press the at least one second protrusion. temporarily adhering one end of the film to the substrate by the temporary adhesive;
cutting the film by a cutting unit to a length corresponding to the substrate;
transferring the substrate to the lower side of the roller by a transfer unit;
detecting the position of the protrusion formed on the substrate by a sensing unit, and adjusting the position of the groove formed on the roller by the roll driving unit corresponding to the position of the protrusion;
adhering the film to the surface of the substrate by moving the roller by the roll driving unit; and
The laminating method using a laminating apparatus, comprising the step of transferring the substrate by the transfer unit, and pressing the film while the roller is rotated by the substrate to adhere to the surface of the substrate.
