DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.
The laminating method according to the present invention can be applied to adhesion of a film layer or a substrate forming a touch screen panel of a wafer-like device such as a smart watch. The film layer or the substrate may have various shapes, for example, a circular or polygonal plate shape. The adhesive layer of the film layer or the substrate is preliminarily given an adhesive such as a synthetic resin adhesive in the form of a film or a coating, and the different layers can be adhered by pressure or heating while being adhered to each other. The laminating method according to the present invention can be applied to adhesion of various layers and can be applied to various kinds of touch screen panel bonding.
Figs. 1A and 1B show an embodiment and an operation structure, respectively, to which the laminating method according to the present invention is applied.
Referring to FIG. 1A, a method of laminating a small touch screen panel for bonding different layers of a small touch screen panel having a plurality of layers according to the present invention includes the steps of: (P11) placing one layer of a touch screen on a lower jig; 1) detecting the placement of the first layer by a detection module (P12); A step (P13) of moving the lower jig to a predetermined position; A step (P14) in which the two layers are fixed to the upper jig; 2) detecting the fixed position of the two layers by the detection module (P15); A step P16 of rotating the upper jig; (P17) of moving the lower jig in the direction of the upper jig; And a step (P18) of bonding the one layer and the two layers.
The lower jig may have a suitable structure for fixing one layer forming the touch screen panel and one layer of the touch screen panel to be adhered to the other layer may be disposed at a predetermined position of the lower jig (P11) . Then, the placement position of the first layer can be detected (P12). The placement position of the first layer can be detected by, for example, a position detection unit such as a camera unit or an optical sensor, and if an error occurs in the placement position of the first layer, the display unit can be displayed and a warning can be generated. On the other hand, if it is detected that the first layer is disposed at the predetermined position, the lower jig can be moved to the bonding position (P13). The lower jig can be moved along a rail unit or guide unit such as, for example, an X-axis guide, and the adhesion position of the lower jig can be predetermined.
When the lower jig is moved to the predetermined position, the two layers adhering to the first layer may be fixed while forming the touch screen panel on the upper jig (P14). The fixing of the two layers can be performed in a state in which the surface on which the two layers are fixed in the upper jig is directed upward. When the second layer is fixed to the upper jig, the fixing position of the second layer can be detected by the detection module (P15). The detection module for detecting the placement position of the first layer and the detection module for detecting the fixed position of the second layer are arranged to detect different positions. In this manner, the production efficiency is improved by detecting the arrangement position of one layer and the fixing position of two layers by different detection modules at different positions. At the same time, positioning of the lower jig and the upper jig is facilitated. The fixing of the two layers to the upper jig can be achieved by, for example, a vacuum adsorption method, but is not limited thereto.
When the two layers are fixed to the upper jig and it is confirmed that there is no error in the fixing position of the two layers, the upper jig can be rotated (P16). The rotation of the upper jig means that the direction of the upper jig is changed so as to be directed downwardly of the upper two layers. The first and second layers are opposed to each other by the rotation of the upper jig. In this state, the lower jig can be moved upward (P17).
By moving the lower jig upward, the first layer and the second layer can be contacted with each other and adhered to each other (P18). Adhesion of the first layer and the second layer can be accomplished in various ways, for example, by pressure, thermal bonding, near-infrared bonding or ultraviolet bonding. Such a whole bonding process can be controlled by the control unit.

The process according to the invention can be carried out automatically by a continuous process or manually, stepwise, or automatically or manually mixed. The method according to the present invention can be operated with various operating structures and is not limited to the embodiments shown.
