AI Technical Summary
The existing keycap spraying process lacks durability and characters tend to fall off paint or break wires.
A new keycap spraying process is adopted, including spraying top paint, UV paint, character radial engraving, and UV paint is filled in the character areas damaged by the radial engraving through spray printing or silk screening to form a UV wrapping effect.
Improves the durability of the keycaps, and the character area forms secondary UV protection, making it less likely to fall off or break wires.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic equipment, and in particular to a key cap spraying process, a key cap and a keyboard. Background Art
[0002] In the prior art, the conventional backlight spray KB process is specifically: primer + topcoat + laser engraving + UV paint, or: topcoat + laser engraving + UV paint. Conventional spray KB relies on UV paint to protect the characters, and is not easy to fall off / break, but is not durable. Summary of the invention
[0003] Purpose of the invention: The present invention aims to provide a keycap spraying process, a keycap and a keyboard with increased durability.
[0004] Technical solution: A keycap spraying process of the present invention comprises:
[0005] (1) Spray a layer of topcoat on the keycap;
[0006] (2) Spray a layer of UV paint on the topcoat;
[0007] (3) Perform character laser engraving;
[0008] (4) Use UV paint to fill in the character areas damaged by laser engraving.
[0009] Furthermore, the step (4) is specifically to fill the character area with UV paint by spray printing.
[0010] Furthermore, the method of filling the character area with UV paint by inkjet printing comprises:
[0011] Use AOI to scan the position and shape of the character area and make a character stencil;
[0012] Print UV paint in the character area to fill the UV paint layer damaged by laser engraving, forming a UV wrapping effect.
[0013] Furthermore, the step (4) is specifically to fill the character area with UV paint by silk screen printing.
[0014] Furthermore, the method of filling the character area with UV paint by silk screen printing includes:
[0015] Use AOI to scan the position and shape of the character area and make a character stencil;
[0016] Silk-screen UV paint is used in the character area to fill the UV paint layer damaged by laser engraving, thus forming a UV wrapping effect.
[0017] Furthermore, the step (4) also includes: taking the text characters as a reference, the filling area is smaller than the characters.
[0018] Furthermore, the step (4) also includes: taking the text characters as a reference, the filling area is larger than the characters.
[0019] Furthermore, the method further comprises, before step (1), spraying a layer of primer on the key cap.
[0020] Based on the same inventive concept, the present invention further provides a keycap, which is sprayed using any of the keycap spraying processes described above.
[0021] Based on the same inventive concept, the present invention further provides a keyboard, comprising a plurality of keycaps, wherein the keycaps are sprayed using any of the keycap spraying processes described above.
[0022] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: 1. It breaks the traditional production process of spraying KB, making it possible for spraying KB to comply with the POD process; the present invention can improve the possibility and timeliness of setting inventory or quickly producing samples; 2. Fill the character area with UV paint by spraying / silk screen printing, etc., to achieve the effect of filling the characters to form a wrapping edge sealing, and the character area forms a secondary UV protection, making the spray layer in the character area more durable, and the characters are not easy to lose paint / break. BRIEF DESCRIPTION OF THE DRAWINGS
[0023] Figure 1 is a schematic diagram of a coating according to an embodiment of the present invention;
[0024] Figure 2 is another schematic diagram of a coating according to an embodiment of the present invention;
[0025] Figure 3 It is a schematic diagram of the character filling effect of an embodiment of the present invention. DETAILED DESCRIPTION
[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.
[0027] like Figure 1 As shown, a key cap spraying process provided in this embodiment includes:
[0028] (1) Spray a layer of topcoat on the keycap;
[0029] (2) Spray a layer of UV paint on the topcoat;
[0030] (3) Perform character laser engraving;
[0031] (4) Use UV paint to fill in the character areas damaged by laser engraving.
[0032] Furthermore, the step (4) is specifically to fill the character area with UV paint by spray printing.
[0033] Furthermore, the method of filling the character area with UV paint by inkjet printing comprises:
[0034] Use AOI to scan the position and shape of the character area and make a character stencil;
[0035] Print UV paint in the character area to fill the UV paint layer damaged by laser engraving, forming a UV wrapping effect.
[0036] Furthermore, the step (4) is specifically to fill the character area with UV paint by silk screen printing.
[0037] Furthermore, the method of filling the character area with UV paint by silk screen printing includes:
[0038] Use AOI to scan the position and shape of the character area and make a character stencil;
[0039] Silk-screen UV paint is used in the character area to fill the UV paint layer damaged by laser engraving, thus forming a UV wrapping effect.
[0040] The step (4) also includes: filling the UV paint area based on the appearance effect and the text characters, and the filling area can be slightly smaller than the characters (such as Figure 3 (A)), or slightly larger than the character (such as Figure 3 (as shown in (B)).
[0041] like Figure 2 As shown, before step (1), a layer of primer is sprayed on the keycap.
[0042] Based on the same inventive concept, the present invention further provides a keycap, which is sprayed using any of the keycap spraying processes described above.
[0043] Based on the same inventive concept, the present invention further provides a keyboard, comprising a plurality of keycaps, wherein the keycaps are sprayed using any of the keycap spraying processes described above.
