Referring to FIG. 4, the anti-spy film pasting method of the present invention is performed by using the above-mentioned anti-spy film pasting device 100, and the steps of the method are described in detail below.

Step S ₁ - referring to FIG. 5, there is provided a privacy filter 7, the privacy filter 7 comprises a body 71, an adhesive layer 72 and an adhesive 71 having opposite side of a master sheet a releasing film 73, the mother sheet 711 and an adsorption side 712, a backing layer 72 is disposed on the adhesive side 711, and the release film 73 is removably disposed on a side of the adhesive layer 72 away from the adhesive side 711.

The types of the master sheets 71 are mainly selected from the following four types of products produced by 3M: ALCF 60° (thickness 0.343±0.05 mm), ALCF-P ABR0 60° (thickness 0.533±0.08 mm), ALCF-P ABR1 Anti-glare 60° (thickness 0.533±0.08mm) or ALCF-P ABR2 Anti-glare 60° (thickness 0.533±0.08mm). As for the adhesive layer 72 and away The processing steps of laminating the film 73 on the adhesive side 711 are well known to those skilled in the art and will not be described again.

As for the size of the privacy sheet 7, since it is necessary to match the size of the screen attachment device 100 and the screen 81 of the display 8, the length and width are in the range of about 30 x 40 mm to 150 x 210 mm, and the thickness is about 0.15 to 0.5 mm. It is better.

Step S ₂ - Referring to Figures 2 and 5, the adsorption side 712 of the privacy sheet 7 is adsorbed. That is, the anti-spy sheet 7 is attached to the adsorption surface 411 of the adsorption platform 4 with the adsorption side 712 attached thereto, and the pump unit is used to evacuate the openings 412 to generate a negative pressure, thereby absorbing the anti-spy Slice 7.

Step S ₃ - Referring to Figure 6, the release film 73 of the privacy sheet 7 is removed. Since the privacy filter 7 is as the step S ₂ is adsorbed manner fixed, so the worker can easily tear releasing film 73 in addition.

Step S ₄ - Referring to Figure 7, the adsorption platform 4 is rotated such that the adhesive side 711 of the privacy sheet 7 faces downward. That is, the plate 41 of the adsorption platform 4 is controlled to rotate 180 degrees by itself as indicated by the arrow in the figure, so that the adsorption surface 411 becomes downward, and the privacy sheet 7 adsorbed on the adsorption surface 411 is rotated by 180 degrees. With the adhesive side 711 facing downward, and continuously pumping by the pump unit, the privacy film 7 does not fall down even in a downward state.

Step S ₅ - referring to FIG. 8, causes the display 8 and the privacy filter 7 wherein one of the first direction D ₁ along the surface of the display screen 81 8 and 7 are aligned parallel to each other privacy filter. In the present embodiment, the display 8 is first fixed to the fixed base 515 of the positioning platform, and then the stage 5 is positioned on the rail 2 along the first direction D _1, the first end 21 moves toward the second end 22 That is, moving to the bottom of the adsorption platform 4, and then automatically positioning, so that the surface of the screen 81 of the display 8 is aligned with each other in parallel with the privacy sheet 7. The details regarding automatic positioning are well known to those of ordinary skill in the art and will not be described again.

Step S ₆ - with reference to FIG. 9 and FIG. 10, one of the display 8 and the privacy preventing sheet 7 is moved in the second direction D ₂ perpendicular to the first direction D ₁ to be close to each other, and the defense is prevented. The adhesive layer 72 of the smear 7 is correspondingly adhered to the surface of the screen 81. That is, the fixing base 51 of the positioning platform 5 is raised in the second direction D ₂ after the positioning of the step S ₄ is completed, so that the surface of the screen 81 of the display 8 is close to the anti-spy sheet 7 in parallel, and finally adhered in parallel. Thereby, the adhesive layer 72 is correspondingly adhered to the surface of the screen 81. Then, the pump unit stops pumping, and the fixed seat 51 descends in the opposite direction of the second direction D ₂ , and then the positioning platform 5 moves in the opposite direction of the first direction D ₁ , and moves from the second end 22 of the slide rail 2 toward the first The one end 21 is returned to the position, and the plate body 41 of the adsorption platform 4 is rotated 180 degrees by itself, so that the adsorption surface 411 is returned upward, and the display 8 is removed from the fixing base 51 of the positioning platform 5, so that the anti-spy film 7 is completed. Paste process.

It should be noted that, in this embodiment, the adsorption platform 4 is relatively immovable, and the positioning platform 5 is relatively moved along the first direction D ₁ , in fact, the opposite is true, that is, the positioning platform 5 is not moved, but is adsorbed. The platform 4 is moved in the first direction D ₁ . Similarly, the movement in the second direction D ₂ can also be varied by different designs, for example, the positioning platform 5 is relatively stationary, and the adsorption platform 4 is lowered in the opposite direction of the second direction D _{2 to} produce various changes.

The plate body 41 and the pumping unit of the adsorption platform can be reversed with the fixing base 51 of the positioning platform 5, that is, the display 8 is rotated by 180 degrees, and the anti-spy sheet 7 is not rotated, and the same effect is achieved. Even in this reversed state, the mount 51 can It is pre-designed to face downward, and the display 8 is fixed from below and the screen 81 is directed downward, so that the display 8 and the anti-spy film 7 do not have to be rotated.

In addition, during the steps and steps, a step of cleaning the screen 81 of the display 8 can be performed to ensure that there is no dust on the screen 81 that would affect the attachment effect.

In summary, the anti-spy film pasting device 100 of the present invention rotates horizontally by the plate body 41 and is relatively moved in the first direction D ₁ by using the adsorption platform 4 and the positioning platform 5, and then the fixing base 51 is along the second position. The direction D ₂ rises, so that the anti-spy sheet 7 can be accurately aligned and adhered to the surface of the screen 81 of the display 8, and the whole process is semi-automated, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
