[0002] With the continuous pursuit of the picture effect of the vehicle instrument panel by users, decorative patterns are often added to the cover plates of existing instrument panels. However, in the prior art, some directly use the silk-screen process to print the resin substrate black to form an all-black effect. However, this method has a single color, and the pattern can only be a conventional geometric figure, resulting in a poor visual experience for users; others directly use UV printing to achieve colorful patterns of multiple colors to enhance the visual experience of users. However, in this method, the adhesion of the pattern is poor, and the paint is likely to fall off, reducing the lifespan of the decorative cover plate; moreover, the resin substrate is prone to scratches, with extremely high process requirements during the processing, prolonging the production time of the product.

In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0037] Unless the context clearly requires otherwise, the words "including", "comprising", and the like in the entire specification and claims should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, the meaning of "including but not limited to".

[0038] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0039] The present invention provides a processing method for a vehicle decorative cover plate. Among them, the vehicle decorative cover plate can be a decorative cover plate for a motorcycle, an electric bicycle, or an automobile, and specifically can be a decorative cover plate at the instrument panel. As Figure 1As shown in the figure, the vehicle-mounted decorative cover plate includes a glass substrate 100, an adhesive layer 200, and a pattern layer 300 that are sequentially stacked. The adhesive layer 200 is formed by coating the surface of the glass substrate after corona treatment with acrylic epoxy resin liquid (also known as "water-soluble UV resin liquid"); the pattern layer 300 is formed by UV printing. Among them, the supply ink cartridges used in UV printing include a blue main ink cartridge, a magenta main ink cartridge, a yellow main ink cartridge, a black main ink cartridge, a green main ink cartridge, and a gray attachment color ink cartridge. That is to say, the surface of the glass substrate 100 facing the adhesive layer is the surface to be treated. First, corona treatment is performed on this surface, and then acrylic epoxy resin liquid is coated to form the adhesive layer 200 with a thickness of 0.05 mm to 0.08 mm. After that, UV printing is performed thereon to form the pattern layer.

[0040] Specifically, the processing method of the vehicle-mounted decorative cover plate is as Figure 2 shown, and it includes the steps:

[0041] S20: Perform corona treatment on the surface to be treated of the glass substrate 100, and within 5 to 10 minutes after the corona treatment, coat the surface to be treated with acrylic epoxy resin liquid to form the adhesive layer 200; among them, the thickness of the adhesive layer 200 is 0.05 mm to 0.08 mm.

[0042] Among them, the glass substrate 100 is a transparent glass plate. Corona treatment, or plasma treatment, is performed on the surface of the side where the pattern layer is set, that is, the surface to be treated, to roughen the surface to be treated so that a layer of particles is formed on its surface to improve the adhesion of the glass substrate 100.

[0043] Considering the timeliness of corona treatment, coat the acrylic epoxy resin liquid within 5 to 10 minutes after the corona treatment of the surface to be treated, such as coating the acrylic epoxy resin liquid within 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, or 10 minutes, etc., so that the adhesive layer 200 can firmly adhere to the glass substrate 100. And in order to balance the firmness of adhesion between the glass substrate and the adhesive layer and between the adhesive layer 200 and the subsequent formed pattern layer 300, the thickness of the adhesive layer is set to 0.05 mm to 0.08 mm, such as 0.05 mm, 0.06 mm, 0.07 mm, or 0.08 mm, etc. At the same time, using such a thin thickness can also reduce the thickness of the entire formed decorative cover plate.

[0044] S40: Print a decorative pattern on the adhesive layer 200 by UV printing to form the pattern layer 300 to form the decorative cover plate; among them, the supply ink cartridges used in UV printing include a blue main ink cartridge, a magenta main ink cartridge, a yellow main ink cartridge, a black main ink cartridge, a green main ink cartridge, and a gray attachment color ink cartridge.

[0045] A decorative pattern is printed on a glass substrate 100 coated with an acrylic epoxy resin liquid. The decorative pattern can be a color pattern formed by a variety of color combinations. In the present invention, a combination of the traditional CMYK mode and RGB mode is used for UV printing. That is to say, the supply ink cartridges in UV printing not only include the four-color ink cartridges of CMYK in the prior art, but also include an attachment color ink cartridge. For example, it can include only one attachment color ink cartridge, specifically a green ink cartridge or a gray ink cartridge, or it can include two attachment color ink cartridges at the same time, that is, a green ink cartridge and a gray ink cartridge are provided at the same time. That is to say, the printing device of the present invention adopts a new printing device, which has at least one more attachment color ink cartridge compared with the CMYK printing device in the prior art. When performing UV printing, the printing device sets the ink supply ratios of the blue main ink cartridge, magenta main ink cartridge, yellow main ink cartridge, black main ink cartridge, green main ink cartridge and gray attachment color ink cartridge according to the needs of the printed decorative pattern. Since the blue main ink cartridge, magenta main ink cartridge, yellow main ink cartridge and black main ink cartridge belong to the four primary colors in the CMYK color gamut, various colors in the CMYK color gamut can be realized. The cooperation between the blue main ink cartridge, magenta main ink cartridge in the CMYK color gamut and the green main ink cartridge in the RGB color gamut can realize various colors in the RGB color gamut. Therefore, the colors of the pattern layer are greatly enriched. In addition, the cooperation of the gray attachment color ink cartridge can make the transition between black and other colors more natural and smooth, so that the colors of the decorative pattern of the printed pattern layer are more real, avoiding the existence of graininess, making the transition from black to other colors more natural, and the colors of each pixel are more delicate.

[0046] In the prior art, some use resin substrates, but such resin substrates are prone to scratches and require high precision in the operation of the processing process; some, in order to increase the adhesion of the substrate, perform etching treatment before coating the adhesive layer or printing the decorative pattern. However, this etching treatment has high requirements for the environment such as vacuum degree, and the processing process steps are too complex, increasing the manufacturing time of the decorative cover plate and also having high requirements for the operation level of the operator.

[0047] The vehicle-mounted decorative cover plate of the present invention uses a scratch-resistant glass substrate. Considering that the adhesion of the glass substrate is weaker than that of the resin substrate, the glass substrate is first subjected to corona treatment and then coated with an acrylic epoxy resin liquid. After the formed adhesive layer 200 is only 0.05 mm to 0.08 mm thick, the adhesion between the adhesive layer 200 and the glass substrate 100 is increased, and then the adhesion to the subsequent printed pattern layer 300 is increased, improving the firmness of the pattern layer 300. Among them, Table 1 shows the results of the pattern layer peeling test on the vehicle-mounted glass cover plate manufactured by the processing method of the present invention. This test is carried out by storing the prepared vehicle glass cover plate samples in an environment with a high temperature of 85°C and a humidity of 85%RH. It can be clearly seen from the table that even after storing for up to four days, the firmness of its pattern layer can be guaranteed. It can be seen that the pattern firmness of the vehicle-mounted decorative cover plate prepared by the method of the present invention is extremely high. Moreover, the present invention uses corona treatment, which has a simpler process and is easier to operate compared to methods such as etching. The pattern layer 300 of the present invention does not directly adopt the existing CMYK printing mode or RGB printing mode, but uses the four-color ink cartridges in the usual CMYK printing mode and the green main ink cartridge in the RGB color gamut, in cooperation with the gray attachment color ink cartridge, to achieve the combination of various colors in the CMYK color gamut and the RGB color gamut, making the colors of the pattern layer richer and more natural. Moreover, the increase in the gray attachment color can make the transition between black and other colors more natural, making the colors of the printed decorative pattern richer, the transition more natural, avoiding the visual effect of graininess, increasing the fineness of the pattern, and thus enhancing the user experience.

[0050] In the above step S20, the corona treatment selects a power of 841 Hz, a frequency of 25 kHz, and an external air pressure of 31.0 kPa, so as to form a better matte surface on the surface of the glass substrate 100 and provide sufficient operation time for the subsequent coating of the adhesive layer.

[0051] In some embodiments, the vehicle-mounted decorative cover plate has a display area and a non-display area, that is, a display screen is further provided at the rear side of the vehicle-mounted decorative cover plate, and the display area corresponds to the display screen at the rear side. In this embodiment, the above processing method only processes the non-display area, and the display area can be used for the display screen at the back to transmit the display picture. In some embodiments, the vehicle-mounted decorative cover plate is all non-display areas, that is, there is no display screen at the rear side of the vehicle-mounted decorative cover plate. In this embodiment, the above processing method processes the entire glass substrate.

[0052] Regardless of which embodiment the vehicle-mounted decorative cover plate is, a light-transmitting area can be set in the non-display area, or the non-display area can be set without a light-transmitting area. In one embodiment, the vehicle-mounted decorative cover plate has a light-transmitting area 400, such as Figure 4 andFigure 5 As shown, between the above-mentioned step S20 and step S40, there is also a step:

[0053] S30: Print a semi-transparent black ink layer on the adhesive layer 200, and the light transmittance of the semi-transparent black ink layer is 40% - 70%.

[0054] In this embodiment, in step S40, UV printing is performed with an ink output amount more than 1.5 times the reference ink amount, that is, the pattern layer is printed on the semi-transparent black ink layer with an ink output amount of 1.5 times or 2 times the reference ink amount. Among them, the area corresponding to the light-transmitting area in the decorative pattern printed by UV printing is a hollow pattern.

[0055] That is to say, when the vehicle-mounted decorative cover plate is used for an instrument panel with a light source, that is, when a light source such as a steering light source or a warning light source is provided at the rear side of the vehicle-mounted decorative cover plate, before printing the pattern layer 300 in the above steps, a semi-transparent black ink layer is first formed on the adhesive layer 200, and the light transmittance of this semi-transparent black ink layer is selected to be 40% - 70%, such as 40%, 45%, 50%, 55%, 60%, 65% or 70%, etc. Thus, after the vehicle-mounted decorative cover plate is installed, even when the light source is not lit, each light-transmitting area 400 does not look very obvious and can form an integrated black effect with the surrounding black, as Figure 4 shown; and when the light source is lit, the light of the light source can be clearly transmitted, playing an indicating effect, as Figure 5 shown. By the above method of adding a semi-transparent black ink layer, the user experience is improved. And in this embodiment, when printing the decorative pattern on the formed semi-transparent black ink layer, it is carried out by setting an ink output amount higher than the conventional one, so that the decorative pattern is basically not affected by the underlying semi-transparent black ink layer, and the fineness of each color can still be ensured.

[0056] In the above step S30, a semi-transparent black ink layer can be formed by UV printing. In a preferred embodiment, a semi-transparent black ink layer is printed on the adhesive layer 200 by screen printing. Screen printing has a simple process, low cost, and the thickness of the semi-transparent black ink layer is easier to control, and it can be printed thinner, so that the thickness increase of the formed vehicle-mounted decorative cover plate is not obvious.

[0057] In a specific embodiment, in step S30, screen printing is performed with black screen printing ink at a concentration of 50% to make the light-transmitting area 400 basically reach a light transmittance of 50%; in step S40, UV printing is performed with an ink output amount twice the reference ink amount. With this configuration, it can not only increase the shielding of the light source when the light source is not lit and enhance the integrated black effect, but also clearly display the indicating effect when the light source is lit; and it can also minimize the ink consumption, and at the same time enable the decorative pattern to present a delicate effect at all times.

[0058] Among them, in step S30, after printing the semi-transparent black ink layer, it is baked at a temperature of 80°C to 90°C for 6 to 10 hours. Especially in the embodiment where the semi-transparent black ink layer is printed by screen printing, it is baked at a temperature of 80°C, 85°C, 88°C or 90°C, and the baking time is 6 hours, 7 hours, 8 hours, 9 hours or 10 hours, etc. Preferably, it is baked at 85°C for 8 hours, so that the semi-transparent black ink layer is basically formed.

[0059] In the embodiment where the non-display area of the vehicle-mounted decorative cover plate does not have a light-transmitting area, in the above step S40, UV printing is directly performed with the ink output of the reference ink volume to save ink volume.

[0060] The thickness of the above pattern layer is preferably 0.1 mm to 0.25 mm. For example, the thickness of the pattern layer 300 is 0.1 mm, 0.12 mm, 0.15 mm, 0.17 mm, 0.175 mm, 0.19 mm, 0.2 mm or 0.25 mm, etc. Preferably, the thickness of the pattern layer 300 is 0.175 mm or thinner. In this way, the thickness of the entire decorative cover plate can be further reduced, making the appearance pattern of the entire decorative cover plate more natural, and the surface is relatively smooth, improving the user's hand feeling and experience; and it can better save ink volume.

[0061] In order to improve the manufacturing accuracy and production efficiency of the vehicle-mounted decorative cover plate, in one embodiment of the present invention, before step S40, there is also step S50: placing a plurality of glass substrates in a plurality of positioning slots of the positioning tooling one by one; in the above step S40, UV printing is performed on a plurality of glass substrates simultaneously. As Figure 3 shown, a plurality of positioning slots 710 are arranged on the positioning tooling 700. For example, a plurality of positioning slots 710 are arranged in a row matrix to arrange a plurality of positioning slots 710 as regularly as possible to facilitate subsequent UV printing. Among them, each positioning slot can be arranged according to the shape of the glass substrate 100. First, printing calibration is performed. For example, a corner of the positioning tooling is used as a calibration point, and then the print head of the printing device is controlled to print on the glass substrates in each positioning slot in turn.

[0062] Among them, a notch can be provided on the side wall of the positioning slot 710. The notch is formed by the side wall being recessed radially outward. Specifically, one, two or more notches can be provided to facilitate the placement and removal of the glass substrate. In one embodiment, a suction cup hole 711 is provided at the bottom of the positioning slot 710. Each suction cup can pass through these suction cup holes and be fixed on the operation platform (detailed below) under the positioning tooling 700. When the glass substrate is placed in the positioning slot 710, it is fixed by these suction cups.

[0063] In some embodiments, the depth of the positioning groove 710 is less than the thickness of the glass substrate 100 to more conveniently place and remove the glass substrate 100 and avoid interference with the tool head of the printing device.

[0064] Continuing to refer Figure 3 , each positioning groove is adapted to the outer shape of the glass substrate. The glass substrate can be placed in the positioning groove after coating the adhesive layer or screen-printing the semi-transparent black ink layer; alternatively, the glass substrate can be placed in the positioning groove first, and then processes such as corona treatment are performed.

[0065] The present invention also provides a processing device for a vehicle-mounted decorative cover plate, which is used to execute the processing method described in any of the above embodiments; the processing device includes:

[0069] A printing device, which is used to execute step S40 and perform UV printing on the glass substrate arranged in the positioning groove. Among them, the supply ink cartridges of the printing device include a blue main ink cartridge, a magenta main ink cartridge, a yellow main ink cartridge, a black main ink cartridge, a green main ink cartridge, and a gray attachment color ink cartridge.

[0070] The processing device further includes a base body, an operation platform, and a bracket arranged on the operation platform. The operation platform is arranged on the base body. The positioning tooling can be arranged on the operation platform, and the printing device is arranged on the bracket. The operation platform can be slidably arranged on the base body in a first direction, and the printing device can be slidably arranged on the bracket in a second direction; alternatively, only one of the operation platform and the printing device can be movably arranged in both the first direction and the second direction at the same time, so as to realize UV printing on each glass substrate through the relative movement of the printing device and the operation platform.

[0071] In some embodiments, the processing device may further include a screen printing device, which is used to execute the screen printing process in step S30. Further, it may also include a baking device, which is used to execute the baking process in step S30.
