Description

TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing a window glass UV mold for a mobile and IT device in which a UV pattern is formed,

The present invention relates to a window glass forming method and a window glass forming method for a mobile and an IT apparatus in which a UV pattern is formed. More particularly, the present invention relates to a method of manufacturing a window glass for a mobile and an IT apparatus (mobile phone, PDA, PMP, UV patterns that can be used to display patterns, designs, and textures (such as SUS) that are totally different from the materials used, as well as effects of 3D (intaglio and concave) by forming UV patterns during the manufacturing process of window glass (UV) molding method for window and glass for mobile and IT devices, and a window glass.

Mobile and IT devices (cell phones, PDA, PMP, notebooks, etc.) are used.

Such mobile and IT devices are provided with a display window. In recent years, a touch screen (TSP: Touch Screen Pad) is generally provided to input information directly to the screen using a hand or a pen on the display window.

On the other hand, a window glass (or an icon sheet or the like, hereinafter referred to as "window glass ") is provided on the exterior of the mobile and IT device display window in order to provide various designs or protect the touch pad.

That is, the window glass constitutes the appearance of the mobile and IT device display windows, and is essential.

Hereinafter, a process of manufacturing a window glass for mobile and IT devices in which a conventional V pattern is formed will be described.

1. Place the processed glass cloth on the jig.

2. Apply UV solution to the glass using a dispensing dispenser.

3. Place the UV mold on which the pattern is formed on the jig using a fixing pin in a state of being separated from the glass.

4. Place the masking film (masking film) on the upper side of the engraved mold with the fixing pin.

In this case, the work area is masked in the UV mold in some cases, so that a separate making film may not be necessary.

5. Pass the jig on which the glass (glass) is seated and the engraved mold film and masking film are fixed to the roller.

6. Through the roller, the irregularities of the mold are contacted with the UV surface applied to the glass, and the mold shape is transferred to the UV surface.

7. UV light is irradiated on the glass with UV mold and masking film to cure.

8. Remove the mold and masking film from the cured glass.

9. Place the glass in a washer to remove any uncured parts.

10. Coating is done to improve reflection or pattern effect on UV-cured glass.

11. Print the ink on the coated glass in the same or slightly smaller size as the glass.

12. The printed and dried glass is put into the etching solution to remove the exposed part from the outside

13. Finish the product by printing afterwards.

Even in the conventional method, the UV liquid can be discharged in a specific amount and shape in order to prevent overflow when rolling, but it can not be discharged in a form similar to a glass shape because it is discharged by a dispenser.

In addition, there is a problem that a process of removing unnecessary UV (e.g., a window portion) and a process of removing a coating portion have to be separately processed.
