Description

Technical Field

[0001] The invention relates to an alarm light button and a preparation process thereof, and in particular to an alarm light button with a symbol and a preparation process thereof. Background Art

[0002] With the advancement of technology, the continuous changes in market demand and the increasing improvement in people's quality of life, consumers' requirements for products are no longer limited to functionality and safety, and consumers have also put forward higher expectations for the visual effects of products.

[0003] The production process of traditional warning lights is usually as follows:

[0004] Step A1: injection molding the button body with red plastic substrate;

[0005] Step A2: spraying a white paint layer on the button body;

[0006] Step A3: spraying a black paint layer on the basis of the white paint layer;

[0007] Step A4: Use laser engraving to remove part of the black paint to expose the white paint layer, which is the white symbol area; remove part of the black paint layer and the white paint layer under the corresponding area in other areas outside the white symbol area to expose the red button body in the corresponding area, which is the red symbol area.

[0008] According to the above process, when the alarm light is made, after the alarm light is turned on, the red symbol area is not bright enough and lacks significance because the button body is injection molded from a red plastic substrate; in the white symbol area, the light source passes through the red button body and the white paint layer in sequence, which makes it easy for the alarm light to have red and white colors misaligned, causing visual double images, and both the white symbol area and the red symbol area are light-transmissive, which easily causes the junction of the red and white symbols to be blurred, resulting in poor visual effects. In order to improve the visual effect of the alarm light, make the red symbol color more vivid, and prevent the red / white symbols from being misaligned, it is urgent to optimize the method of the traditional alarm light button symbol process. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide an alarm light button with a symbol and a preparation process thereof.

[0010] The technical solution adopted by the present invention is as follows: an alarm light button with a symbol, comprising a button body, the button body is sprayed with a light-transmissive primer layer and an opaque covering layer in sequence, a light-transmissive pattern layer is printed on the covering layer, and symbols are laser-engraved in the pattern layer area, the button body is light-transmissive at least in the area corresponding to the symbol, and the symbol includes two display areas, one of which is formed by laser engraving the pattern layer, and the other is formed by laser engraving the exposed primer layer.

[0011] The button body is injection-molded from a transparent plastic substrate or a white plastic substrate.

[0012] The primer layer is made of red paint and is light-transmissive, the covering layer is made of black paint and is not light-transmissive, and the pattern layer is made of white ink and is light-transmissive.

[0013] The laser engraving forms the same laser engraving area for the two display areas.

[0014] The process of preparing a warning light button with a symbol comprises the following steps:

[0015] Step S1: injection molding a button body, wherein at least a portion of the button body is light-transmissive;

[0016] Step S2: spraying a light-transmissive primer layer on the button body;

[0017] Step S3: spraying a light-proof covering layer on the light-permeable primer layer;

[0018] Step S4: printing a light-transmissive pattern layer on the light-opaque covering layer;

[0019] Step S5: laser engraving removes a portion of the pattern layer area and the covering layer corresponding to the portion of the pattern layer, so that the corresponding primer layer is exposed, and the exposed primer layer and the remaining pattern layer form a symbol.

[0020] In step S1, the button body is injection molded from a transparent plastic substrate or a white plastic substrate.

[0021] In step S2, the primer layer is a light-transmissive red paint.

[0022] In step S3, the covering layer is opaque black paint.

[0023] In step S4, the pattern layer is light-transmissive white ink.

[0024] According to several aspects, the present invention discloses an alarm light button with a symbol and a preparation process thereof. According to a first aspect of the present invention, the alarm light button with a symbol comprises a button body, which is injection molded from a transparent plastic substrate or a white plastic substrate to ensure that the light source in the substrate can smoothly pass through the button body.

[0025] According to the second aspect of the invention, a translucent primer layer (red) is sprayed on the button body. The red color is bright compared to the material color of the button body (transparent or white). The light source in the button body passes through the button body and the translucent primer layer (red paint) in turn. The visibility of the sprayed red paint is greatly improved, so that a clear and bright red symbol can be displayed.

[0026] According to the third aspect of the present invention, an opaque covering layer is sprayed on the light-transmissive primer layer, and the light source in the button body can pass through the button body and the light-transmissive primer layer in turn, but cannot pass through the opaque covering layer. By providing the light-transmissive primer layer and the opaque covering layer, different light-transmitting effects are achieved.

[0027] According to the fourth aspect of the present invention, a light-transmissive pattern layer is printed on an opaque covering layer, and a symbol is laser-engraved in the pattern layer area, and the symbol includes two display areas, one of which is formed by laser-engraving the pattern layer, and the other is formed by laser-engraving the exposed primer layer. The two display areas of the symbol are the first display area and the second display area, the first display area is the remaining pattern layer portion after the laser engraving of the pattern layer, and the second display area is the primer layer area exposed by the laser engraving. Using this method, the symbol on the button body forms different areas, and the combination of color coatings in each area is different, and finally different light transmission effects are achieved in different areas.

[0028] According to the fifth aspect of the present invention, the coating combination of the first display area in the symbol display area is, from top to bottom, a light-transmissive pattern layer, an opaque covering layer, and a light-transmissive primer layer. Since the light-transmissive pattern layer is under the opaque covering layer, the light source in the button body cannot be refracted to the pattern layer in this area under the coating combination of the first display area, that is, the first display area of ​​the symbol display area is opaque.

[0029] According to the sixth aspect of the invention, the coating of the second display area in the symbol display area is a light-transmitting primer layer, and the light source in the button body can be refracted through the button body to the light-transmitting primer layer, that is, the second display area of ​​the symbol display area is light-transmitting.

[0030] According to the seventh aspect of the present invention, the area outside the display area of ​​the symbol is the third display area, and the coating combination of the third display area is, from top to bottom, an opaque covering layer and a translucent primer layer. Under the coating combination of the third display area, the light source in the button body cannot pass through the opaque covering layer, that is, the third display area is opaque.

[0031] According to the eighth aspect of the present invention, the first display area is opaque, the second display area is translucent, and the third display area is opaque. This avoids blurred boundaries between different areas after the alarm light is turned on, and the alarm light symbol is not misplaced. The second display area is brightly colored and can produce a clear and visible effect.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The button body of the present invention is injection molded with a light-transmitting plastic substrate, and then a light-transmitting primer layer is sprayed on the button body. Compared with directly using a plastic substrate of the primer color to mold the button body, the primer can achieve a brighter color and more significant effect;

[0034] 2. In the present invention, a covering layer is used to isolate light under the light-transmitting pattern layer, so that one of the two display areas of the symbol is light-transmitting and the other is opaque, so that the junction of the two display areas is clearly visible, without misalignment and with good visual effects.

[0035] For example, when the primer layer is red paint, the covering layer is black paint, and the pattern layer is white ink, there is a layer of opaque black paint between the red paint and the white ink, so that the white symbol display area in the symbol display area is opaque, while the red symbol display area is translucent, so that the junction of the red / white symbols is clearly visible, and the red symbol area has only a layer of translucent red paint, ensuring that the red / white symbols are not misaligned after the alarm light is turned on, and the visual effect is good.

[0044] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

Therefore, the directions and positions used are for explaining and understanding the present invention, but not for limiting the scope of protection of the present invention.

[0047] Embodiment 1:

[0048] like Figure 1 As shown, the manufacturing process of a traditional alarm light button is usually as follows:

[0049] Step A1: injection molding the button body with red plastic substrate;

[0050] Step A2: spraying a white paint layer on the button body;

[0051] Step A3: spraying a black paint layer on the basis of the white paint layer;

[0052] Step A4: Use laser engraving to remove part of the black paint to expose the white paint layer, which is the white symbol area; remove part of the black paint layer and the white paint layer under the corresponding area in other areas outside the white symbol area to expose the red button body in the corresponding area, which is the red symbol area. The white symbol area and the red symbol area form the final symbol of the alarm light button.

[0053] When an alarm light is manufactured according to the above process, after the alarm light is turned on, since the button body is injection-molded from a red plastic substrate, the color of the red symbol area is not bright enough and lacks prominence; in the white symbol area, since the light source passes through the red button body and the white paint layer in sequence, the red and white colors of the alarm light are easily misaligned, causing visual double images, and both the white symbol area and the red symbol area are light-transmissive, which easily causes blurring of the boundary between the red and white symbols, resulting in poor visual effects.

[0054] like Figures 3 to 7 As shown, in order to solve the above technical problems, this embodiment proposes an alarm light button with a symbol, comprising a button body 1, on which a light-transmissive primer layer 2 and an opaque covering layer 3 are sprayed in sequence, a light-transmissive pattern layer 4 is transferred and printed on the covering layer 3, and a symbol 5 is laser-engraved in the pattern layer 4 area, the button body 1 is light-transmissive at least in the area corresponding to the symbol 5, and the symbol 5 includes two display areas, one of which is formed by laser engraving the pattern layer 4, and the other is formed by laser engraving the exposed primer layer 2.

[0055] The button body 1 is made of a transparent plastic substrate or a white plastic substrate by injection molding.

[0056] The primer layer 2 is made of red paint and is light-transmissive, the covering layer 3 is made of black paint and is not light-transmissive, and the pattern layer 4 is made of white ink and is light-transmissive.

[0057] The laser engraving areas of the two display areas formed by laser engraving are the same. The two display areas of the symbol 5 are the first display area 51 and the second display area 52. The first display area 51 is the remaining pattern layer part after the laser engraving of the pattern layer 4, and the second display area 52 is the primer layer 2 area exposed by the laser engraving.

[0058] Embodiment 2:

[0059] like Figures 2 to 3 As shown, this embodiment provides a process for preparing the alarm light button with a symbol in Embodiment 1, comprising the following steps:

[0060] Step S1: injection molding a button body 1, wherein at least a portion of the button body 1 is light-transmissive;

[0061] Step S2: spraying a light-transmissive primer layer 2 on the button body 1;

[0062] Step S3: spraying a light-proof covering layer 3 on the light-permeable primer layer 2;

[0063] Step S4: printing the light-transmissive pattern layer 4 on the light-opaque covering layer 3;

[0064] Step S5: laser engraving is performed to remove a part of the pattern layer 4 and the covering layer 3 corresponding to the part of the pattern layer 4 , so that the corresponding primer layer 2 is exposed, and the exposed primer layer 2 and the remaining pattern layer 4 form a symbol 5 .

[0065] In step S1 , the button body 1 is injection-molded with a transparent plastic substrate or a white plastic substrate to ensure that the light source in the substrate can pass through the button body 1 smoothly.

[0066] In step S2, the primer layer 2 is a translucent red paint, and the red color is bright relative to the material color (transparent or white) of the button body 1. The light source in the button body 1 passes through the button body 1 and the translucent primer layer 2 (red paint) in turn, and the visibility of the sprayed red paint is greatly improved, so that a clear and bright red symbol can be displayed.

[0067] In step S3, the covering layer 3 is opaque black paint, and the opaque covering layer 3 is sprayed on the translucent primer layer 2. The light source in the button body 1 can pass through the button body 1 and the translucent primer layer 2 in turn, but cannot pass through the opaque covering layer 3. By setting the translucent primer layer 2 and the opaque covering layer 3, different light-transmitting effects are achieved.

[0068] In step S4 , the light-transmissive pattern layer 4 is transferred onto the light-opaque covering layer 3 .

[0069] In step S5, a symbol 5 is laser engraved in the pattern layer 4 area, and the symbol 5 includes two display areas, one of which is formed by laser engraving the pattern layer 4, and the other is formed by laser engraving the exposed primer layer 2. The two display areas of the symbol 5 are a first display area 51 and a second display area 52. The first display area 51 is the remaining portion of the pattern layer 4 after laser engraving the pattern layer 4, and the second display area 52 is the area of ​​the primer layer 2 exposed by laser engraving. In this way, the symbol 5 on the button body 1 forms different areas, and the combination of color coatings in each area is different, and finally different light transmission effects are achieved in different areas.

[0070] The coating combination of the first display area 51 is, from top to bottom, a light-transmissive pattern layer 4, an opaque covering layer 3, and a light-transmissive primer layer 2. Since the opaque covering layer 3 is located under the light-transmissive pattern layer 4, the light source in the button body 1 cannot be refracted to the pattern layer 4 in this area under the coating combination of the first display area 51, that is, the first display area 51 is opaque.

[0071] The coating of the second display area 52 is a light-transmitting primer layer 2 , and the light source in the button body 1 can be refracted through the button body 1 to the light-transmitting primer layer 2 , that is, the second display area 52 is light-transmitting.

[0072] The area outside the symbol 5 is the third display area 53. The coating combination of the third display area 53 is, from top to bottom, an opaque covering layer 3 and a translucent primer layer 2. Under the coating combination of the third display area 53, the light source in the button body 1 cannot penetrate the opaque covering layer 3, that is, the third display area 53 is opaque.

[0073] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
