That is, as the first alignment check unit 81 rotates the master roll 20 mounted on the installation frame 41, the first alignment check unit 81 checks the alignment state of the first alignment mark 21. The horizontal state of the rotating shaft of 20) is adjusted.

Hereinafter, a description will be given of the operation of the thin mold winding device according to an embodiment of the present invention.

First, as shown in FIG. 1, the thin plate mold 30 having a fine pattern formed on one side thereof is mounted on the jig member 71 of the mold holding unit 70. In this case, the other side surface on which the adhesive member 31 of the thin plate mold 30 is provided is installed to face forward.

On the other hand, in this embodiment, the adhesive member 31 is to be provided in the thin plate mold 30, but it is obvious that such an adhesive member 31 may be provided in the master roll 20.

Then, the master roll 20 is mounted on the installation frame 41 of the master roll mounting unit 40. In this case, the master roll 20 mounted on the installation frame 41 aligns the horizontal state of the master roll 20 through the first alignment check unit 81.

That is, when rotating the master roll 20 mounted on the installation frame 41 by the motor 45, the first alignment check unit 81 is the first alignment mark 21 formed on the master roll 20 Detects the image, and arranges the master roll 20 to the correct position based on the image information detected by the monitoring unit (not shown).

Next, as shown in FIG. 2, the thin plate mold 30 mounted on the jig member 71 is transferred between the master roll 20 and the pressing roller 63 by the transfer unit 72.

In this case, the thin plate mold 30 is transferred to the correct position to be wound on the master roll 20 through the second alignment check unit 83.

That is, the second alignment checking unit 83 detects an image of the second alignment mark 33 formed on the thin mold 30, and detects the first alignment through the first alignment checking unit 81. The transfer unit 72 so that the second alignment mark 33 of the thin mold 30 is disposed at a position corresponding to the first alignment mark 21 of the master roll 20 based on the image information of the mark 21. ) To sort.

As shown in FIG. 3 in the state where the alignment is completed, the roll pressing unit 60 is operated so that the end portion of the thin mold 30 can be snapped between the master roll 20 and the pressing roller 63.

That is, as the cylinder member 65 of the roll pressing unit 60 presses the one end portion 62 of the support frame 61, the pressing roller 63 is moved toward the master roll 20 to press the pressing roller 63. And press the thin plate mold 30 located between the master roll 20.

Then, as shown in FIG. 4, when the master roll 20 rotates in the counterclockwise direction (arrow direction), the pressing roller 63 rotates in the clockwise direction while contacting the surface of the thin plate mold 30.

As a result, the surface on which the adhesive member 31 of the thin plate mold 30 placed between the master roll 20 and the pressing roller 63 is provided is pressed by the pressing roller 63 to the outer circumferential surface of the master roll 20. As the roll 20 and the pressing roller 63 rotate in opposite directions, the thin plate mold 30 is wound around the master roll 20.

In this case, the thin plate mold 30 is conveyed downward by the transfer unit 72 at the same speed as the winding speed of the master roll 20.

As such, when the master roll 20 is rotated once, the thin plate mold 30 having the fine pattern is wound on the outer circumferential surface of the master roll 20, thereby completing the pattern roll mounted on the roll-to-roll system.

Therefore, since the production of the pattern roll formed with a fine pattern to be mounted on the roll-to-roll printing system is facilitated by the thin mold winding apparatus according to an embodiment of the present invention, productivity is improved.

In addition, when the alignment precision is required, the alignment of the thin plate mold 30 wound around the master roll 20 and the misalignment of the fine pattern and the position error of the fine pattern may be realized by the alignment check unit 80. As it can be minimized, the production cost is also significantly reduced as the defective rate of the pattern roll is reduced and the yield is improved.
