The second laminating unit 204 is arranged above and spaced apart from the first laminating unit 202 and is implemented to be movable up and down.

Hereinafter, a method of laminating using a laminating device having such a structure will be described.

Referring to FIG. 2A, the first sheet 210 is loaded on the first laminating unit 202. According to an embodiment of the present invention, an alignment is set before placing the first sheet 210 on the first laminating unit 202, and the first sheet 210 is aligned with the first sheet 210 in accordance with the alignment. It is loaded on the laminating unit 202. After the initial alignment is set once, there is no need to set the alignment again when loading the next sheet, and the sheet is loaded according to the preset alignment. Here, sheet loading may be performed manually by a person or may be automated.

Subsequently, the first laminating part 202 loaded with the first sheet 210 moves along the guide line 200 under the second laminating part 204 as shown in FIG. 2B. That is, the first sheet 210 is conveyed in the left direction in FIG. 2.

Subsequently, the second laminating portion 204 is lowered and positioned on the first sheet 210 as shown in FIG. 2C. In this case, the lower surface of the second laminating unit 204 and the first sheet 210 may not be in direct contact with each other, but may be spaced apart by a minute interval.

Subsequently, the second laminating unit 204 adsorbs the first sheet 210, and moves upward in a state in which the first sheet 210 is adsorbed as shown in FIG. 2D. In this case, the first laminating part 202 moves back to the position of Fig. 2A.

Subsequently, the second sheet 212 to be laminated with the first sheet 210 is loaded onto the first laminating portion 202 as shown in FIG. 2D.

Subsequently, the first laminating portion 202 loaded with the second sheet 212 moves along the guide line 200 to the bottom of the second laminating portion 202, as shown in FIG. 2E. After that, the second laminating unit 204 descends. As a result, the first sheet 210 overlies the second sheet 212 as shown in FIG. 2E. In this case, since the sheets 210 and 212 are aligned when they are placed on the first laminating unit 202, the sheets 210 and 212 are arranged to match in the state of Fig. 2E.

Subsequently, the roller 206 located inside the first laminating part 202 moves and applies a force to the second sheet 212. As a result, since the first sheet 210 is supported by the second laminating portion 204, the first sheet 210 and the second sheet 212 are laminated. For example, the upper surface of the second sheet 212 may be coated with an adhesive solution, and the first sheet 210 and the second sheet 212 may be laminated according to the movement of the roller 206.

Subsequently, the second laminating unit 204 releases the force adsorbing the first sheet 210 and moves upward. As a result, the second laminating portion 204 and the first sheet 210 are separated, and the laminated first sheet 210 and the second sheet 212 are placed on the first laminating portion 202.

Subsequently, the first laminating part 202 moves to the original position along the guide line 200 as shown in FIG. 2 (F). The user may separate the laminated sheets 210 and 212 seated on the first laminating unit 202 to obtain a finished product.

Thereafter, the user may repeatedly obtain the laminated sheets by repeatedly performing the loading process, the transfer process, the adsorption process, and the laminating process of FIGS. 2A to 2F.

Here, the whole laminating process of the present invention may be automated or the rest of the process except for loading the sheets 210 and 212 may be automated.

In the conventional sheet laminating method, the sheets are laminated using a rolling part having a cylindrical shape, so that the laminating process is complicated and takes a long time for laminating. Moreover, the defect rate was high and the yield fell.

However, the sheet laminating method of the present invention laminates the sheets 210 and 212 through a simple loading process, a straight line transfer process and a laminating process, so that the laminating process is easy and the time for laminating can be shortened.

In addition, since the alignment is made when the sheet 210 or 212 is loaded on the first laminating part 202, defects hardly occur during the laminating process, and thus the yield can be significantly improved as compared with the prior art.
