Problems solved by technology
[0011] As described above, in the conventional bonding method, in the process of peeling the functional sheet from the base sheet of the continuous laminated sheet and bonding it to the object, it is difficult to sufficiently suppress the detachment of the functional sheet due to peeling and charging. static electricity
As a result, static electricity will accumulate in the bonded object, which will cause electrical destruction of the object due to grounding, etc.

Embodiment Construction
[0055] First, refer to figure 1 The structure of the functional sheet of this embodiment will be described. The functional sheet 6 is processed in the state of a laminated sheet 7 laminated on the base sheet 1 having a predetermined thickness T1 (30 μm≦T1≦50 μm). Hereinafter, the structure of the functional sheet 6 will be specifically described by taking the electromagnetic wave shielding sheet directly attached to the display surface of the plasma display panel as an example.
[0056] Such as figure 1 As shown in (a), the functional sheet 6 has a predetermined thickness T4 ( 1 μm≤T4≤10 μm) and a hard coat layer 5 having a predetermined thickness T5 (2 μm≤T5≤10 μm) are sequentially laminated.
[0057]As materials, films such as polyethylene terephthalate (PET), polycarbonate (PC), and polymethyl methacrylate (PMMA) are used for the base material sheet 1 and the resin film layer 3 . The adhesive layer 2 is an adhesive based on an acrylic monomer, and contains a reaction ...

The present invention provides a sheet bonding method and a sheet bonding apparatus, which can inhibit the static electricity of a functional sheet, generated by stripping electrification in a step of stripping the functional sheet from a base material sheet of continuous laminated sheets and bonding the functional sheet (6) on an object (8). The sheet bonding method of stripping the functional sheet (6) from the laminated sheets (7) continuously supplied along a length direction comprises the steps of: conveying the functional sheet (6) towards the object (8), cutting the functional sheet (6) into a length required by bonding, stripping the functional sheet (6) in a manner of enabling a base material sheet to be along a stripping block (20), and bonding the stripped functional sheet (6) on the object (8) through using the stripping block (20). When the base material sheet (1) is provided with negative electricity because of stripping, the stripping block (20) is formed by a material with an electrified column located near the negative side of the base material sheet (1); and when the base material sheet (1) is provided with positive electricity, the stripping block (20) is formed by a material with an electrified column located at the positive side of the base material sheet (1).
Description
technical field [0001] The present invention relates to a sheet lamination method and lamination device for peeling a sheet from a base sheet and pasting it on a panel, and more specifically, to laminating a sheet with electromagnetic wave shielding on a display panel such as a plasma display panel or a liquid crystal panel. , A sheet laminating device and a sheet laminating method for functional sheets with functions such as light transmittance adjustment and chromaticity adjustment. Background technique [0002] Traditionally, functional sheets have been pasted on the surface of the display panel. Figure 7 The side cross section of the vicinity of the bonding part of the conventional sheet bonding apparatus which bonds a functional sheet to objects, such as a display panel, is schematically shown. The functional sheet 111 is prepared by being wound up in a roll shape in a state laminated on the base sheet 113 . As a general bonding method, it is known that the functional...
