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.
