As described above, the light-transmitting decoration part manufactured by the method in the prior art has many parts and complicated structure, and has certain defects, so the present invention provides a more optimized manufacturing method 100 of the light-transmitting part and a light-transmitting part 200 manufactured based on the method 100. The manufacturing method 100 of the light-transmitting part is simple in process, and the light-transmitting part 200 manufactured based on the method 100 is simplified in structure and richer in decorative effect.

Fig. 1 shows a flow chart of a method 100 for fabricating a light-transmitting member of the present invention. As shown in FIG. 1, the method 100 includes steps S110-S140. According to the method 100 of the invention, a light-transmitting member may be made based on a light-transmitting membrane and a flexible light-source body.

Fig. 2 shows a schematic structural diagram of a light-transmitting member 200 according to an embodiment of the present invention, and the light-transmitting member 200 can be manufactured based on the method 100 of the present invention.

As shown in fig. 2, the light-transmitting member 200 includes a pre-molded plastic film member 220, and a flexible light source body 230 under the pre-molded plastic film member 220. In the embodiment according to the present invention, the light transmitting member 200 is manufactured based on the pre-molded film member 220 and the flexible light source body 230 by first manufacturing the pre-molded film member 220 based on the light transmitting film.

Fig. 3 shows a schematic diagram of a light transmissive film 210 in an embodiment in accordance with the invention. Fig. 4 shows a schematic structural view of a flexible light source body 230 in an embodiment in accordance with the invention.

According to the method 100 of the present invention, the light-transmitting member 200 may be integrally injection molded. Specifically, according to the method 100 of the present invention, the preformed adhesive film member 220 and the flexible light source body 230 may be integrally injection molded to manufacture the light transmissive member 200.

As shown in fig. 1, the method 100 is adapted to step S110.

In one embodiment, the light transmissive film 210 and the flexible light source body 230 may be manufactured before step S110. After the light transmitting film 210 and the flexible light source body 230 are manufactured, step S110 is started.

In step S110, the light transmissive film 210 is heated based on a first predetermined temperature, and the heated light transmissive film 210 is subjected to a plastic suction process to obtain a pre-molded film part 220. Specifically, the heated transparent film 210 is placed in a plastic suction mold, and the plastic suction mold is used to perform plastic suction processing on the heated and softened transparent film, so as to obtain a preformed plastic film 220 with a predetermined shape. That is, the light-transmitting film 210 after being heated and softened is processed by a plastic suction process to obtain a preformed plastic film 220 with a predetermined shape. It should be noted that the specific shape of the preformed plastic film member 220 obtained after the plastic-absorbing treatment is not limited in the present invention, and those skilled in the art can set the shape of the preformed plastic film member 220 according to actual requirements.

The first predetermined temperature is a temperature at which the light-transmitting film 210 can be softened without melting the light-transmitting film 210, so that the softened light-transmitting film 210 is subjected to a plastic-suction molding process to obtain the pre-molded plastic film 220. Here, the present invention does not specifically limit the value of the first predetermined temperature.

In one embodiment, the first predetermined temperature is in a range of 80-150 ℃.

In one embodiment, as shown in fig. 3, the light-transmitting film 210 includes a transparent substrate layer 213, and a glue layer 214 located below the transparent substrate layer 213. It should be understood that the shape of the transparent module 210 is changed by the plastic-suction molding process, and the structure of the transparent module 210 is not changed, so that the preformed plastic film member 220 obtained by plastic-suction processing of the transparent film 210 also includes a transparent substrate layer and a glue layer under the transparent substrate layer.

Subsequently, in step S120, the above-mentioned preformed plastic film piece 220 is placed into a mold of an injection molding device, and the preformed plastic film piece 220 in the mold is heated based on a second predetermined temperature, so as to activate a glue layer on the preformed plastic film piece 220. It should be noted that the second predetermined temperature is a temperature at which the glue layer on the preformed film member 220 can be activated to render the glue layer tacky for application. Here, the present invention does not specifically limit the value of the second predetermined temperature.

In one embodiment, the second predetermined temperature is in a range of 150-180 ℃.

According to an embodiment, after the preformed film member 220 is obtained by the plastic-suction molding process and before the step S120 is performed, the preformed film member 220 is further subjected to a cutting process, for example, the preformed film member 220 may be placed in a cutting mold for punching so as to cut off an excess edge portion of the preformed film member 220.

Subsequently, in step S130, the flexible light source body 230 is placed into a mold of an injection molding apparatus, where the flexible light source body 230 is disposed in the mold on a side adjacent to the glue layer of the pre-molded glue film piece 220. In this way, the flexible light source body 230 will be bonded to the pre-molded plastic film member 220 in the mold through the activated glue layer on the pre-molded plastic film member 220. In one embodiment, flexible light source body 230 is a flexible sheet structure.

According to one embodiment, the two ends of the flexible light source body 230 are respectively provided with positioning holes. After placing the flexible light source body 230 in a mold, the flexible light source body 230 may be positioned based on the positioning holes and the flexible light source body 230 is fixed in an injection mold. In this way, the position of the flexible light source body 230 relative to the preformed adhesive film member 220 can be ensured to be more precise, so that the structure of the finally manufactured light-transmitting member 200 is more precise and uniform, which is beneficial to mass production.

Finally, in step S140, the injection molding device is used to integrally injection mold the flexible light source body 230 and the pre-molded plastic film 220, which are bonded together, specifically, the injection molding layer 240 is formed by closing the mold of the injection molding device and injecting a plastic melt into the mold, so as to integrally injection mold the flexible light source body 230 and the pre-molded plastic film 220 in the mold, thereby obtaining the light-transmitting component. It should be noted that the injection molded layer is formed on the other side of the flexible light source body 230 opposite to the preformed adhesive film piece 220, as shown in fig. 2, the injection molded layer is located below the flexible light source body 230, and the preformed adhesive film piece 220 is located above the flexible light source body 230. That is, in the light transmissive member 200 obtained by integral injection molding, the flexible light source body 230 is located between the pre-mold adhesive film 220 and the injection molding layer 240.

Fig. 3 shows a schematic diagram of a light transmissive film 210 in an embodiment in accordance with the invention.

According to one embodiment, before step S110, a specific method of manufacturing the light-transmitting film 210 shown in fig. 3 is as follows:

a transparent substrate layer 213 is obtained, and the decoration layer 212 is formed on the transparent substrate layer 213. Here, the material of the transparent base material layer 213 is, for example, ABS, that is, the transparent base material layer is an ABS base material. In one embodiment, the decorative layer 212 may be formed by printing one or more layers over the transparent substrate layer using an ink screen printing process, i.e., screen printing ink over the transparent substrate layer to form a decorative layer including one or more ink printed layers. Here, each layer of ink may be printed in a different pattern, so that the decorative layer formed includes one or more ink printed layers of different patterns. It should be noted that the number of ink printed layers and the specific pattern of each layer included in the decorative layer 212 are not limited by the present invention. Based on the ink printing layers with different patterns on the light-transmitting film 210, the finally manufactured light-transmitting component can be more abundant in style, stronger in decoration and capable of improving the decoration effect.

Further, a first protective layer 211 is formed over the decorative layer 212. Here, the material of the first protective layer 211 may include one or more of PMMA, PET, PC, ABS. The first protective layer 211 serves as a protection for the decorative layer. It should be noted that the specific material of the first protection layer is not limited in the present invention.

Finally, a glue layer 214 is formed under the transparent base material layer 213.

Thus, the light-transmitting film 210 in step S110 is manufactured. Here, the thickness of the light transmissive film 210 may be 0.1 to 10 mm. However, it should be understood that the thickness of the light-transmitting film obtained by the present invention is not particularly limited.

Fig. 4 shows a schematic structural view of a flexible light source body 230 in an embodiment in accordance with the invention.

According to one embodiment, before step S110, a specific method of making the flexible light source body 230 shown in fig. 4 is as follows:

a flexible conductive film 233 is obtained, and after the flexible conductive film 233 is cleaned, laser etching processing, such as ultraviolet laser etching processing, is performed on the flexible conductive film 233, so that a pattern profile of the light-emitting layer is etched on the flexible conductive film 233.

Subsequently, a light-emitting layer 232 is formed over the flexible conductive film 233 after the laser etching process. Here, the light emitting layer 232 may be formed by a fluorescent material screen printing process, that is, a fluorescent material is screen printed on the flexible conductive film after laser etching based on the etched pattern profile, so that the light emitting layer 232 is formed on the flexible conductive film.

Subsequently, electrode material printing is performed under the flexible conductive film 233 to form a conductive layer 234.

Finally, a second passivation layer 231 is formed on the light emitting layer 232 and under the conductive layer 234, respectively. Here, the material of the second protective layer 231 may include one or more of PMMA, PET, PC, ABS. It should be noted that the specific material of the second passivation layer is not limited in the present invention.

In one embodiment, first, optical adhesives are respectively attached on the light-emitting layer 232 and under the conductive layer 234 to form optical adhesive layers. Thus, the second protection layer 231 can be attached by an optical adhesive layer, so that the second protection layer is fixedly attached above the light emitting layer 232 and below the conductive layer 234 by the optical adhesive layer, that is, the second protection layer 231 is formed on the optical adhesive layer.

Thus, the flexible light source body 230 in step S130 is manufactured. Here, the sheet-shaped flexible light source body 230 has a thickness of 0.2 to 15 mm. However, it should be understood that the present invention is not limited to the thickness of the flexible light source body produced.

According to the method 100 of the present invention, the light-transmitting member 200 can be further manufactured based on the light-transmitting film 210 and the flexible light source body 230 manufactured in the above-described embodiments. Specifically, the light-transmitting film 210 is subjected to a plastic suction process to form a pre-molded film member 220, and the pre-molded film member 220 and the flexible light source body 230 are subjected to an integral injection molding to form the light-transmitting member 200. Therefore, the manufacturing process is simple, the manufactured light-transmitting part 200 is simpler and more integrated in structure, the occupied space is small, and the decorative effect is richer.

It should be noted that, based on the light-transmitting member 200 made of the light-transmitting film 210 and the flexible light source 230, when the flexible light source provides light with different colors, the light-transmitting film 210 can exhibit different pattern and texture effects. For example, when the flexible light source body is not lit, the light transmissive film 210 exhibits a pattern effect of the first ink printed layer; when the flexible light source body provides red light, the light-transmitting film 210 has a pattern effect of the second ink printed layer; when the flexible light source body provides green light, the light transmissive film 210 exhibits a pattern effect of the third ink printed layer, and the like. In addition, the flexible light source body can also display light of multiple colors at the same time, for example, half of the light is displayed as red light, and the other half of the light is displayed as green light, so that more personalized pattern effects can be presented by combining multiple layers of ink printing layers with different patterns.

According to an embodiment of the present invention, as shown in fig. 2, the light-transmitting member 200 manufactured by the method 100 of the present invention includes a preformed adhesive film member 220, a flexible light source body 230 under the preformed adhesive film member 220, and an injection molding layer 240 under the flexible light source body 230. The preformed plastic film 220 is formed by performing a plastic-suction process on the heated transparent film 210, in other words, the transparent film 210 softened by heating is processed by a plastic-suction process, so as to obtain the preformed plastic film 220 with a predetermined shape. Here, since the light-transmitting film sheet 210 includes the transparent base layer 213 and the glue layer 214 located below the transparent base layer 213, the preform glue film 220 obtained by the suction molding of the light-transmitting film sheet 210 also includes the transparent base layer and the glue layer located below the transparent base layer. It should be noted that the specific shape of the preformed plastic film member 220 obtained after the plastic-absorbing treatment is not limited in the present invention, and those skilled in the art can set the shape of the preformed plastic film member 220 according to actual requirements.

The flexible light source body 230 is adhered to the preformed adhesive film member 220 through the adhesive layer on the preformed adhesive film member 220. The injection molding layer 240 is formed on the other side of the flexible light source body 230 opposite to the preformed film member 220 by injection molding. In this way, the flexible light source body 230 is located between the pre-molded plastic film piece 220 and the injection molded layer 240.

According to one embodiment, as shown in fig. 3, the light-transmitting film 210 further includes a decorative layer 212 formed on the transparent substrate layer 213. Decorative layer 212 includes one or more printed layers of ink formed by screen printing. Here, each ink printed layer may be printed in a different pattern, i.e. the decorative layer may comprise one or more ink printed layers of different patterns. It should be noted that the number of ink printed layers and the specific pattern of each layer included in the decorative layer are not limited by the present invention. Based on the ink printing layers of the multiple layers of different patterns on the light-transmitting film 210, the light-transmitting part is richer in presented style, stronger in decoration, and improved in decoration effect.

The light-transmitting film 210 further includes a first protective layer 211 formed on the decorative layer 212. Here, the material of the first protective layer may include one or more of PMMA, PET, PC, ABS. The first protective layer plays a role in protecting the decorative layer. It should be noted that the specific material of the first protection layer is not limited in the present invention.
