Description

Technical Field

[0001] The invention relates to the technical field of electronic product manufacturing, and in particular to a production process for a UV light-curing embossed key panel. Background Art

[0002] The existing keypad production process uses a metal embossing mold. First, UV-curable glue is sprayed onto the metal embossing mold surface. A transparent plastic substrate is then placed over the glue. A UV curing device is then applied to the transparent plastic substrate to dry and harden the UV-curable glue, forming the embossed keypad layer. Next, an ink layer is screen-printed onto the transparent plastic substrate after the keys have been formed. Finally, the printed panel sheet is die-cut to produce the finished product. Because the existing process cures the glue onto the transparent plastic substrate before printing the ink layer, the material remains in a sheet state during printing, requiring only sheet-based printing machines for printing, resulting in low printing efficiency. Summary of the Invention

[0003] The present invention provides a UV light-curing molding embossed key panel production process to solve the above technical problems.

[0004] In order to achieve the above object, the technical solution of the present invention is:

[0009] S4 curing: Use UV light curing equipment to irradiate the bottom of the transparent convex molding mold to dry and harden the UV light curing glue;

[0010] S5 demoulding and cutting: remove the cured panel sheet and then die-cut to obtain the finished product.

[0011] Preferably, the stamping mold body in step S1 is performed by roll-to-roll printing.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Combine Figures 1-8 As shown, the key panel includes, from top to bottom, an ink layer 1, a transparent plastic substrate 2, and a glue layer 3. The glue layer is formed by applying UV light-curing glue on a transparent convex molding mold 4 and curing it.

[0030] A UV light curing molding embossed key panel production process,

[0031] The following steps are involved:

[0032] S1 Stamp: Screen-printing ink is applied to a transparent plastic substrate, eliminating the uneven surface of the material caused by pre-molding raised buttons, which makes it difficult to roll up for production. Roll-to-roll printing is used, and products are printed in multiple colors and multiple times, significantly improving production efficiency.

[0033] S11 Slicing: After the mold is completed, the printed transparent plastic substrate is sliced according to the designed size;

[0034] S2 Gluing: Spray UV light-curing glue on the surface of a transparent embossing mold made of glass material; the transparent embossing mold can be irradiated from the side of the mold, solving the problem of existing processes that the metal mold is not light-transmitting and can only be irradiated from the transparent material surface, so that the ink can be printed first and then photocured, rather than only being able to print after UV light curing. The transparent embossing mold is made of glass material, and its surface is frosted. Concave carving and high-gloss treatment are performed at the position where embossing is required. After processing, the entire mold is tempered. Compared with metal molds, the glass mold used in this application has the advantages of low cost and strong resistance to chemical corrosion.

[0035] S3 Lamination: Cover the non-printing surface of the transparent substrate after printing ink with the transparent embossed molding mold sprayed with UV light curing glue.

[0036] S4 curing: Use UV light curing equipment to irradiate the bottom of the transparent convex molding mold to dry and harden the UV light curing glue.

[0037] S5 Demolding and Cutting: Remove the cured panel sheet and die-cut it to obtain the finished product. This process first prints the ink and then cures the UV light-curing glue through a transparent embossed mold, eliminating the impact of the embossed sheet on printing in the original process and significantly improving the efficiency of the printing process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
