Problems solved by technology

[0003] In recent years, in response to the popularity of portable electronic products and the miniaturization of electrical products, the thickness of the keyboard has gradually become thinner. Sheet-shaped keyboards with button protrusions on the surface and touch bumps on the bottom surface; however, the sheet-shaped keyboards produced by injection molding are limited in thickness to a certain extent, and are not easy to be quickly molded, and are made of thermoplastic colloid. The flaky keyboard formed has poor wear resistance and pressure concentration when pressing, and also has problems of poor dustproof and waterproof effects.
[0004] Furthermore, the sheet keyboard must be marked with patterns (patterns, characters or symbols) for users to read, and most of the current pattern marks are produced by means of pasting or coating, resulting in a discrepancy after a period of use. Pattern peeling problem

Embodiment Construction

[0039] For ease of explanation and understanding, the said upper and lower film belts in the present invention refer to the film material belts before forming, and the formed films are called upper and lower films; again, the upper and lower films are not in contact with each mold. is the first surface, and the contact surface in contact with each mold is the second surface. When the upper and lower films are glued together, the second surface of the upper film is glued to the first surface of the lower film.

[0040] see figure 1 and Figure 1A As shown, it is a schematic diagram and a detailed description of the molding method of the membrane keyboard unit of the present invention. The molding method of the membrane keyboard unit includes the upper film forming operation (A), the lower film forming operation (B), and the printing operation (C). ) and gluing operation (D) and other steps.

[0041] The upper film forming operation (A) includes a step of opening a first mold ...

Abstract

The invention provides a method for forming a thin film type keyboard group unit. The thin film type keyboard group unit is formed by binding an upper layer thin film and a lower layer thin film. Themethod comprises the following steps: firstly, quickly forming keystroke convex parts and convex points on second surfaces of an upper thin film band and a lower thin film band by ultraviolet cured resin by using a rolling means and an ultraviolet irradiation means; and secondly, performing pattern printing on a second surface of the upper layer thin film by using a printing means so as to form the thin film type keyboard group unit provided with patterns after binding the upper layer thin film and the lower layer thin film. Thus, the method for forming the thin film type keyboard group unit has the advantages of low cost, high efficiency and high production precision.

Description

field of invention [0001] The present invention provides a keyboard molding technology, especially a molding method of a film-type keyboard unit that is beneficial to rapid production. Background technique [0002] The keyboard is one of the important interfaces used in electronic products for users to operate, such as most computers, PDAs, media player devices, mobile phones, electrical remote controls, electrical control boxes... and other electronic products , will be provided with a keyboard for the user to input and set. [0003] In recent years, in response to the popularity of portable electronic products and the miniaturization of electrical products, the thickness of the keyboard has gradually become thinner. Sheet-shaped keyboards with button protrusions on the surface and touch bumps on the bottom surface; however, the sheet-shaped keyboards produced by injection molding are limited in thickness to a certain extent, and are not easy to be quickly molded, and are ...
