In order to realize the key provided by the present invention, the key cap is preferably prepared by using 3 methods:
double-color molding:
injection molding the first material "A' shaped first preform to obtain a first portion of the keycap;
injection molding a second material over the first portion ""external frame of the profile, forming a second preform, i.e. surrounding said"The second preform is formed on top of the first preform of the type, in other words, the second preform surrounds said ""type around the upper part of the first preform, wherein the outer edge of the orthographic projection of the second preform on a plane coincides with the outer edge of the orthographic projection of the first preform on the plane; printing ink on the top surfaces of the first prefabricated member and the second prefabricated member to form an ink film; the first preform is a different color than the second preform.
And irradiating the ink film on the ink film according to a preset pattern by using a first condition to obtain the keycap with the pattern on the surface.
Still further, the color of the ink film is the same as the color of the second preform. Wherein the irradiation on the ink film using the first condition forms a pattern in a predetermined pattern, the pattern being in a region opposed to a top surface of the upper portion of the first preform.
As shown in fig. 1, a side view of a keycap prepared by a two-color forming method provided in embodiment 1 of the present invention includes: a first preform 1, a second preform 2, an ink film 3. The first prefabricated member forms a part a of the first panel and a lower part b2 of the side wall of the key cap, the second prefabricated member forms an upper part b1 of the side wall of the key cap and the other part of the first panel a, and the ink film covers the upper surface of the first panel. I.e. covering the top surface of the first portion of the first pre-form and the top surface of the second pre-form.
According to the invention, the double-color molding is preferably used for enabling the boundary lines of the upper part and the lower part of the side wall to be more obvious and horizontal, the printing ink on the surface is used for enabling the film on the first panel to be thinner, and if the first material or the second material is directly molded, the thickness is thicker, the problems of scorching or unclear patterns and the like can occur during laser engraving, and the quality and the aesthetic degree of the keycaps are influenced. The light transmittance of the first material is greater than that of the second material, the first material is preferably a light-permeable material, the second material is a non-light-permeable material, after printing ink is printed on the first prefabricated member formed by the first material, laser engraving is carried out, the ink film is peeled off, the surface of the light-permeable first prefabricated member is exposed, and the first prefabricated member is a pattern in a preset shape, so that the pattern can transmit light, and the pattern is more obvious and attractive.
According to the invention, the protruding part and the lower part of the first prefabricated part can be in right angle transition or circular arc transition, the invention is not limited, the second prefabricated part (the frame body) and the first prefabricated part can be perfectly combined by using two-color molding, no matter how the protruding part and the lower part are in transition, the second prefabricated part (namely, the second prefabricated part) and the first prefabricated part form a three-dimensional keycap, and the outer surface of the second prefabricated part (namely, the second prefabricated part) and the outer surface of the lower part of the first prefabricated part form the outer surface of the side wall of the keycap of the invention.
According to the invention, the printing ink can be directly formed in one piece in the mould by using in-mould transfer printing, or the prepared prefabricated member can be taken out of the mould and manually or mechanically coated with the ink. The method preferably uses the in-film transfer printing, because the in-film transfer printing is short in time consumption, good in printing effect and even in thickness of the ink film, the thickness of the ink film is thinner than that of the ink film which is manually coated, and the surface of the ink film is provided with auxiliary layers such as an anti-oxygen layer, so that the ink film has better weather resistance, wear resistance and corrosion resistance. According to the present invention, the ink film formed by in-film transfer may be formed directly on the first panel, in which case the color of the second preform is the same as the color of the ink film. Of course, the upper part of the outer surface of the second prefabricated member can be further covered when the first panel is covered, so that the second prefabricated member can not transmit light and achieve the same effect of color. I.e. both the first panel and the upper part of said side wall are light-tight. In this case, the color of the second preform and the color of the ink film may not be the same. Second prefabricated member
According to the invention, the two-color molding specifically comprises the following steps:
1) select a material and in-film rendition film preparation key cap

And tearing off the release layer and the base material on the film after demolding to obtain a prefabricated part, and irradiating the upper surface of the prefabricated part by using laser according to a preset pattern to obtain the keycap with the pattern. As shown in fig. 2, includes a first preform 1 and an ink film 2.
2) The keycaps were prepared using two materials and an in-film transfer film:

According to the present invention, if the key cap is prepared using one material and an in-film transfer film, the first material can be directly formed into a concave member, which is printed with an in-film transfer opaque ink on the top surface of the concave member and the upper portion of the side wall, because the ink film is thin, the appearance is not affected. If two materials and an in-mold transfer film are used to prepare the key cap, the color of the second material is preferably the same as the color of the in-mold transfer film.
According to the invention, the key cap further comprises a connecting structure for connecting the first panel and the side wall together. The connecting mechanism is preferably a separate axle hole connecting mechanism, and the side wall is assembled on the first panel. The method for preparing the keycap by separately molding and then assembling comprises the following steps:
