Abstract
The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.
Claims17
A method for manufacturing a keycap of a keyboard device, comprising:
- providing a top fabric layer having a top surface;
- providing one of an in-mold-forming film and an in-mold-decoration film to have a bottom surface;
- attaching the top fabric layer to the one of the in-mold-forming film and the in-mold-decoration film to form a film structure;
- molding the film structure in a first mold to form a forming film, wherein the forming film includes an upper surface being the top surface and a lower surface being the bottom surface;
- injecting a plastic material into a space between the lower surface and a second mold to form a keycap body;
- and
- combining the keycap body with the forming film to form the keycap.
A method for manufacturing a keycap for a keyboard device having plural keys configured thereon, wherein each the key has a film structure, and the keycap is used with each the key, comprising:
- providing a top fabric layer;
- providing a molding film beneath the top fabric layer;
- causing the molding film and the top fabric layer to form the film structure including a first inner surface having a first outline;
- providing a keycap body beneath the film structure and including an upper surface having a second outline;
- and
- matching the second outline with the first outline to form the keycap.
A method for manufacturing a keycap of a keyboard device, comprising:
- providing a top fabric layer having a top surface;
- providing a molding film having a bottom surface;
- attaching the top fabric layer with the molding film to form a film structure which has an upper surface being the top surface and a lower surface being the bottom surface;
- disposing the film structure in a mold having a mold surface to form a space between the film structure and the mold surface;
- and
- injecting a plastic material into the space to mold the film structure and to form a keycap body to be combined with the film structure to form the keycap.
