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 keyboards with key protrusions on the surface and touch bumps on the bottom; however, the sheet keyboard produced by injection molding is limited in thickness to a certain extent, and it is not easy to be quickly molded, and it is 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

[0036] For ease of explanation and understanding, the said upper and lower film belts in the present invention refer to the film strips 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. The surface is the first surface, and the contact surface 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.

[0037] see figure 1 and Figure 1A As shown, it is a schematic diagram and a detailed description of the continuous molding method of the film keyboard unit of the present invention. The continuous molding method of the membrane keyboard unit includes printing operation (A), upper layer film forming operation (B), and lower layer film forming operation. (C) and gluing operation (D) and other steps.

[0038] Printing operation (A), printing a design on the second surface of a...

Abstract

The invention provides a method for continuously 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. The method comprises the following steps: firstly, performing pattern printing on a second surface of an entire roll of an upper thin film band by using a printing means; and secondly, quickly forming keystroke convex parts and convex points on the second surfaces of the entire roll of the upper thin film band and an entire roll of a lower layer thin film body respectively after curing anultraviolet cured resin by using a rolling means and an ultraviolet irradiation means so as to form the upper layer thin film and the lower layer thin film, and form the thin film type keyboard groupunit with patterns after binding the upper layer thin film and the lower layer thin film. Thus, the method for continuously 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 continuous molding method for 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 keyboards with key protrusions on the surface and touch bumps on the bottom; however, the sheet keyboard produced by injection molding is limited in thickness to a certain extent, and it is not easy to be quickly molded, and it is made of the...
