The color and position of the color block are determined based on the design requirements of the automotive knob light-emitting component. A light-shielding layer is then formed on the processed surface. The area of the light-shielding layer corresponding to the color block is removed to expose the color block, thus obtaining the automotive knob light-emitting component.
[0004] With respect to the above-mentioned related technologies, the lighting effect of the automobile knob lighting part is poor, and the lighting color is uneven. Summary of the Invention
[0005] In order to enhance the luminous effect of an automobile knob luminous component and ensure the uniformity of its luminous color, the present application provides a manufacturing method, system, terminal and storage medium for an automobile knob luminous component.

[0033] Calculating the uniformity of the transmission color;
[0034] When the uniformity is greater than the uniformity threshold, a smoothing operation is performed on the color block in the processing area.
[0035] By adopting this technical solution, when removing the varnish, the system detects whether any residual varnish remains, determines whether the transmittance color of the processed area is uniform, and then provides appropriate treatment measures to completely remove the residual varnish and improve the uniformity of the processed area.

[0039] According to the target line, the residual shading paint is removed to obtain the remaining condition of the residual shading paint;
[0040] If the remaining condition indicates that the residual varnish is not completely removed, repeat the above four steps;
[0041] If the remaining condition indicates that the remaining light-shielding paint is completely removed, the subsequent steps are performed.
[0042] By adopting the above technical solution, a target line is set according to the shape and position of the residual shading paint, and the residual shading paint is removed according to the target line to improve the removal rate of the residual shading paint and ensure the luminous effect and uniformity of the luminous color of the car knob luminous parts.

[0071] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 To the attached Figure 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.
[0072] Car knob luminous parts are widely used in various types of vehicles. This application embodiment takes the car knob luminous parts applied to air conditioner knobs as an example to illustrate. The car knob luminous parts include working mode and off mode. The car knob luminous parts are provided with a luminous area, which will emit light in the working mode. Please refer to Figure 1 The light-emitting areas of the car knob light-emitting part include area 101, area 2 102 and area 3 103. When the car knob light-emitting part is in working mode, area 101 will emit blue light, area 2 102 will emit white light, and area 3 103 will emit red light.
[0073] The embodiment of the present application discloses a method for manufacturing a car knob luminous part. Figure 2 , the method comprising:
[0074] Step S201: Determine a processing area on the processing surface of the transparent light-emitting component, the processing area including a first area, a second area and a third area, the first area, the second area and the third area are in the shape of a circular ring segment, and the first area, the second area and the third area are connected in sequence along the clockwise direction.
[0075] Transparent luminous parts are colorless and transparent or white and transparent objects. The shape of transparent luminous parts is consistent with the luminous parts of car knobs. Please refer to Figure 1 The shape of the transparent light-emitting element consists of two parts: a circular tubular component 11 at the bottom and a circular pancake-shaped component 10 at the top. The radius of the circular pancake-shaped component 10 is greater than or equal to the radius of the circular tubular component 11.
[0076] The processing surface is located on the side of the pancake-shaped component that is away from the tubular component. The processing area is a preset area on the processing surface, and the shape and position of the processing area are determined by the luminous area of the car knob luminous part.
[0077] Step S202: pad printing a first color block on the first area and pad printing a second color block on the second area, wherein the thickness of the first color block is not greater than a first preset thickness and the thickness of the second color block is not greater than a second preset thickness.
[0078] Pad printing is a technology that transfers printing paint, coating or ink to form color blocks of specific shapes in specific areas on the processing surface of transparent luminous parts.
[0079] Optionally, the first color block is yellow and the second color block is green.
[0080] Optionally, each time the first color block is pad-printed, a first transition region is provided at the edge of the first color block. The first transition region surrounds the first color block, and a thickness of the first transition region is less than a thickness of the first color block.
[0081] Optionally, each time the second color block is pad-printed, a second transition region is provided at the edge of the second color block, the second transition region surrounds the second color block, and the thickness of the second transition region is less than the thickness of the second color block.
[0082] The first preset thickness and the second preset thickness are preset empirical values, and technicians can adjust the specific values of the first preset thickness and the second preset thickness according to actual needs. The first preset thickness and the second preset thickness can be the same or different.
[0083] For example, please refer to Figure 3 A first color block 31 is formed on the processing surface first, and then a second color block 32 is formed. A first transition area 311 is formed at the edge of the first color block 31 , and a second transition area 321 is formed at the edge of the second color block 32 .
[0084] Step S203: pad printing a light-transmitting paint on the processed surface to form a primer layer, which covers the processed surface.
[0085] Translucent paint is a type of paint or ink that allows light to penetrate. In this application, the primer layer can include the first and second color blocks during subsequent processing. Furthermore, the primer layer can adjust the color of the first and second color blocks to ensure that the final illuminated automotive knob component meets design standards.
[0086] For example, please refer to Figure 3 , a light-transmitting varnish is printed on the processed surface to form a primer layer 33.
[0087] Step S204: pad printing the third color block on the first area corresponding to the primer layer, and pad printing the fourth color block on the third area corresponding to the primer layer.
[0088] Optionally, the third color block is blue and the fourth color block is red.
[0089] For example, please refer to Figure 3 , a third color block 34 is printed on the first area corresponding to the primer layer 31 , and a fourth color block 35 is printed on the third area corresponding to the primer layer 31 .
[0090] Step S205: pad printing a light-shielding varnish on the primer layer to form a protective varnish layer.
[0091] The light-shielding paint is a coating or ink with high hiding power and low light transmittance, and is used to block light from penetrating. In the present application, the light-shielding paint can protect the third color block, the fourth color block and the primer layer underneath, and on the other hand, the light-shielding paint can allow light to escape from a specific area.
[0092] For example, please refer to Figure 3 , a light-shielding varnish is transferred onto the primer layer to form a protective varnish layer 36 .
[0093] Step S206: performing a removal operation on the processing area corresponding to the protective paint layer to obtain the automobile knob luminous component.
[0094] Optionally, the removal operation is a laser removal operation.
[0095] Furthermore, the present application utilizes different removal operations for different processing areas. For the first area, the removal operation is performed on the first area corresponding to the protective paint layer until the third color block is exposed. For the second area, the removal operation is performed on the second area corresponding to the protective paint layer until the primer layer is exposed. For the third area, the removal operation is performed on the third area corresponding to the protective paint layer until the fourth color block is exposed.
[0096] For example, please refer to Figure 3, the processing area corresponding to the protective paint layer 36 is removed, the third color block 34 is exposed in the first area, the primer layer 33 is exposed in the second area, and the fourth color block 35 is exposed in the third area.
[0097] By employing this technical solution, processing areas are planned on the transparent light-emitting component, and different numbers and colors of color blocks are added to different processing areas. This technical solution can thus form multiple layers of color blocks in the automotive knob light-emitting component, resulting in a better lighting effect and more uniform color.
[0098] In the following embodiment, after forming the first color block and the second color block, in order to ensure that the first color block and the second color block are qualified, the first color block and the second color block need to be detected. The following embodiment takes the detection of the first color block as an example to illustrate, and the embodiment of the present application discloses a color block detection method. Figure 4 , the method comprising:
[0099] Step S401: collecting discrete hue values at detection points on a first color block.
[0100] The detection point is a discrete point on the first color block. The position of the detection point on the first color block can be pre-set or randomly generated.
[0101] Discrete hue values refer to the hue values at discrete points. Hue values are used to describe the basic properties of color. In this embodiment, hue values refer to the degrees of a color mapped to a circular color wheel. For example, red is 0 degrees, green is 120 degrees, and blue is 240 degrees.
[0102] Step S402: Calculate the variance of discrete hue values to obtain the hue value variance.
[0103] Hue value variance is used to indicate the degree of dispersion of discrete hue values.
[0104] Step S403: When the hue value variance is less than a preset variance, the mean of the discrete hue values is calculated to obtain a first hue value.
[0105] The preset variance is a preset empirical value, and technical personnel can adjust the specific value of the preset variance according to actual needs.
[0106] On the other hand, in the case where the hue value variance is not less than the preset variance, it indicates that the color of the first color block is seriously uneven, which will affect the lighting effect of the car knob lighting part.
[0107] Step S404: Detect whether the first hue value is greater than a lower hue value limit and less than an upper hue value limit.
[0108] The lower limit of the hue value and the upper limit of the hue value are preset empirical values, and the lower limit of the hue value is smaller than the upper limit of the hue value.
[0109] Step S405: If not, adjusting the thickness of the first color block according to the first hue value.
[0110] If the first hue value is less than the lower hue value limit, or greater than the upper hue value limit, the color corresponding to the first hue value deviates significantly from the design standard, causing the luminous color of the automotive knob light-emitting component to deviate significantly. Furthermore, because the color of the paint / ink used for the first color block is fixed, after pad printing the first color block, the first hue value of the first color block depends on its thickness. Therefore, this application adjusts the thickness of the first color block.
[0111] Step S406: If yes, execute the subsequent steps.
[0112] If the first hue value is between the lower limit and the upper limit of the hue value, it means that the color corresponding to the first hue value meets the design standard, and thus subsequent steps S203 to S206 are executed.
[0113] It should be noted that the steps for detecting the second color block are consistent with the steps provided in this embodiment and will not be described in detail here.
[0114] By adopting the above technical solution, the hue value of the first color block is detected to ensure that the first hue value of the first color block is between the upper limit and the lower limit of the hue value, so that the luminous color of the automobile knob luminous part meets the design standards and has a better luminous effect.
[0115] In the following embodiments, if the thickness of the first color block needs to be adjusted, a corresponding adjustment method needs to be adopted according to the actual thickness of the first color block. Therefore, the embodiment of the present application discloses a method for adjusting the thickness of the color block. Figure 5 , the method comprising:
[0116] Step S501: Obtain the standard thickness of the first color block.
[0117] The standard thickness is a preset thickness, and the standard thickness refers to the thickness of the first color block that meets the design standard under ideal circumstances.
[0118] Step S502: converting the first hue value into the thickness of the first color block to obtain the actual thickness.
[0119] The first hue value is positively correlated with the thickness of the first color block. The greater the thickness of the first color block, the greater the first hue value, and the darker the color of the first color block appears to the human eye. For example, the actual thickness is obtained by searching the hue-thickness database for the thickness corresponding to the first hue value. The hue-thickness database is used to record the mapping relationship between hue values and color block thicknesses. The data in the hue-thickness database can be obtained by technicians through repeated experiments.
[0120] Step S503: When the standard thickness is greater than the actual thickness, the difference between the standard thickness and the actual thickness is calculated to obtain a first thickness difference.
[0121] When the standard thickness is greater than the actual thickness, it indicates that the first color block is too thin and the thickness of the first color block needs to be increased in subsequent steps.
[0122] Step S504: performing pad printing on the first color block according to the first thickness difference.
[0123] Optionally, the thickness of the first color block after pad printing is controlled by adjusting the pressure value used for pad printing. In this step, the thickness of the ink for pad printing needs to be controlled to be maintained at a first thickness difference. Exemplarily, in a pressure-thickness database, the pressure value corresponding to the first thickness difference is retrieved to obtain the pad printing pressure. According to the pad printing pressure, the pad printing scraper is controlled to perform pad printing so that the thickness of the first color block after this pad printing increases by the first thickness difference. Among them, the pressure-thickness database is used to record the mapping relationship between the pad printing pressure and the thickness of the color block, and the data in the pressure-thickness database can be obtained by technicians through repeated experiments.
[0124] Step S505: when the standard thickness is smaller than the actual thickness, generating a hue value distribution of the first color block according to the discrete hue values.
[0125] When the standard thickness is smaller than the actual thickness, it indicates that the first color block is too thick and the thickness of the first color block needs to be reduced in subsequent steps.
[0126] The hue value distribution is used to represent the correspondence between hue values and positions on the first color block. For example, after obtaining discrete hue values, a plane coordinate system is established, and a detection point is marked in the plane coordinate system. The discrete hue value is assigned to the detection point. Based on the detection point and the discrete hue value, other coordinate points in the plane coordinate system are interpolated to obtain fitted hue values for the other coordinate points. Based on the discrete hue values and the fitted hue values, a hue value distribution is obtained.
[0127] Step S506: According to the hue value distribution, an area having a thickness greater than a standard thickness is determined on the first color block to obtain a processing area.
[0128] Since the hue value of the first color block is directly related to its thickness, the hue value distribution can be converted into the thickness distribution of the first color block. According to the thickness distribution, the area with a thickness greater than the standard is determined to obtain the processing area.
[0129] Step S507: Calculate the difference between the actual thickness and the standard thickness to obtain a second thickness difference.
[0130] The second thickness difference refers to the difference between the actual thickness and the standard thickness.
[0131] Step S508: performing a removal operation on the processed area according to the second thickness difference.
[0132] Optionally, the removal operation is performed by a laser removal operation. Exemplarily, the processing time and laser power of the laser removal operation are set according to the second thickness difference. The removal operation is performed on the processing area according to the processing time and laser power.
[0133] By adopting the above technical solution, when the first hue value of the first color block does not meet the requirements, the actual thickness is calculated based on the first hue value, and the actual thickness is compared with the standard thickness. Based on the relationship between the actual thickness and the standard thickness, a corresponding method is selected to adjust the thickness of the first color block, thereby ensuring that the thickness of the first color block meets the requirements. In this way, the luminous color of the automotive knob light-emitting component meets the design standards and the luminous effect is improved.
[0134] In the following embodiment, after the processing area corresponding to the protective paint layer is removed, it is necessary to ensure that there is no residue of the light-shielding paint in the processed area after treatment, and no uneven color blocks will appear. Therefore, the embodiment of the present application discloses a color block processing method 1. Figure 6 , the method comprising:
[0135] Step S601: Detect whether there is residual light-shielding paint in the processing area.
[0136] If there is residual shading paint in the processing area, step S602 to step S603 are executed;
[0137] If there is no residual light-shielding paint in the processing area, steps S604 to S606 are executed.
[0138] Residual opaque varnish is the opaque varnish remaining in the processed area corresponding to the protective varnish layer.
[0139] Optionally, a camera may be used to capture an image of the protective paint layer. Since the color of the protective paint layer is different from the colors of the third color block, the fourth color block, and the primer layer, residual light-shielding paint can be identified in the processing area corresponding to the light-shielding paint layer image based on the color of the light-shielding paint layer.
[0140] Step S602: If yes, obtain the remaining position of the remaining light-shielding paint.
[0141] The residual position is the position of the remaining opaque paint in the processed area. Optionally, the residual position can be obtained from the protective paint layer image.
[0142] Step S603: removing the remaining light-shielding paint according to the remaining position.
[0143] The removal operation may be a laser removal operation. Exemplarily, after obtaining the residual position, a laser removal operation is performed on the residual varnish at the residual position, and a real-time image of the residual position is obtained in real time. When it is detected that the residual varnish in the real-time image is completely removed, the laser removal operation is stopped.
[0144] Step S604: If not, obtain the transmission color of the processing area.
[0145] Transmittance color refers to the color of light after it passes through the processed area. For the first area, the transmitted color refers to the color after the light passes through the first color block, the primer layer, and the third color block; for the second area, the transmitted color refers to the color after the light passes through the second color block and the primer layer; and for the third area, the transmitted color refers to the color after the light passes through the primer layer and the fourth color block.
[0146] Optionally, test points are set in the processing area, wherein each area in the processing area is set with at least two test points, and the transmission color at the test points is obtained.
[0147] Transmission color is expressed using hue values.
[0148] Step S605: Calculate the uniformity of the transmission color.
[0149] Uniformity describes the consistency of the transmitted color distribution within the processing area. Optionally, the mean of the hue values corresponding to the transmitted color within the processing area is calculated to obtain a reference value. The color difference between the hue values corresponding to the transmitted color and the reference value is calculated to obtain uniformity.
[0150] In this step, the uniformity of the transmission color needs to be calculated for each area in the processing area. For example, the transmission color of the first area is obtained, and the uniformity corresponding to the first area is calculated based on the transmission color of the first area.
[0151] Step S606: When the uniformity is greater than the uniformity threshold, a smoothing operation is performed on the color block in the processing area.
[0152] When the processing area includes the first area, the third color block is ground flat. When the processing area includes the second area, the primer layer is ground flat. When the processing area includes the third area, the fourth color block is ground flat.
[0153] In another implementation of this embodiment, when the uniformity is not greater than the uniformity threshold, it means that the color distribution of the processed area is uniform and no other processing is required.
[0154] By adopting this technical solution, when removing the varnish, the system detects whether any residual varnish remains, determines whether the transmittance color of the processed area is uniform, and then provides appropriate treatment measures to completely remove the residual varnish and improve the uniformity of the processed area. This enhances the luminous effect of the automotive knob light-emitting component and ensures its luminous color uniformity.
[0155] In the following embodiment, a method for removing the residual shading paint will be disclosed to ensure that the residual shading paint is completely removed. Therefore, the embodiment of the present application discloses a second method for processing color blocks. Figure 7 , the method comprising:
[0156] Step S701: Obtain the edge contour and center position of the remaining light-shielding paint according to the remaining position.
[0157] The center position refers to the center of the minimum circumscribed rectangle of the remaining varnish.
[0158] Optionally, in the protective paint layer image, edge detection is performed on the area where the residual light-shielding paint is located to obtain the edge contour of the residual light-shielding paint.
[0159] Optionally, a minimum bounding rectangle is generated according to the edge contour of the residual shading paint, and the center position is obtained according to the position coordinates of the minimum bounding rectangle.
[0160] Step S702: Calculate the distance from the edge contour to the center position to obtain the contour distance.
[0161] Optionally, take any point on the edge contour and obtain its coordinates. Based on the coordinates and the center position, the contour distance is obtained.
[0162] Step S703: Take the maximum value of the contour distances to obtain the maximum contour distance, and generate a target line corresponding to the maximum contour distance. The target line points from the edge contour to the center position.
[0163] For example, after determining the maximum contour distance, the edge contour point corresponding to the maximum contour distance is obtained, and a directed line segment is drawn from the edge contour point to the center position to obtain the target line.
[0164] Step S704: According to the target connection line, the residual shading paint is removed to obtain the remaining situation of the residual shading paint.
[0165] The removal operation can be performed using a laser. For example, after acquiring the target line, the laser removal operation is performed with the starting point of the target line as the starting point and the ending point of the target line as the ending point. Simultaneously, a real-time image of the residual position is acquired in real time. The remaining amount of the residual paint is determined based on the real-time image.
[0166] Step S705: If the remaining condition indicates that the residual light-shielding paint has not been completely removed, repeat the above four steps.
[0167] If the remaining condition indicates that the residual light-shielding paint has not been completely removed, then the above steps S701 to S704 are repeated to remove the residual light-shielding paint again.
[0168] Step S706: If the remaining condition indicates that the remaining light-shielding paint is completely removed, the subsequent steps are executed.
[0169] If the remaining condition indicates that the residual shading paint is completely removed, it can be considered that the car knob luminous parts have reached the factory standard.
[0170] By adopting the above technical solution, a target line is set according to the shape and position of the residual shading paint, and the residual shading paint is removed according to the target line to improve the removal rate of the residual shading paint and ensure the luminous effect and uniformity of the luminous color of the car knob luminous parts.
[0171] In the following embodiment, a method for smoothing the color block in the processing area will be disclosed to ensure that the residual light-shielding paint is completely removed. The embodiment of this application discloses a color block processing method three. Figure 8 , the method comprising:
[0172] Step S801: Obtain a second hue value corresponding to the transmission color.
[0173] The second hue value refers to the hue value of the transmitted color.
[0174] Step S802: converting the second hue value into the thickness of the color block in the processing area to obtain thickness distribution.
[0175] Thickness distribution is used to describe the thickness of the color block at different locations in the processing area.
[0176] For example, in the hue-thickness database, the thickness corresponding to the second hue value is retrieved to obtain the thickness of the color block in the processing area, wherein the hue-thickness database is used to record the mapping relationship between the hue value and the thickness of the color block, and the data in the hue-thickness database can be obtained by technicians through repeated experiments.
[0177] Step S803: generating a color block removal depth according to the thickness distribution.
[0178] Exemplarily, a thickness mean is calculated according to the thickness distribution, and the thickness mean is set as the color block removal depth.
[0179] Step S804: performing a smoothing operation on the color blocks in the processing area according to the color block removal depth.
[0180] The flattening operation adopts mechanical polishing. For example, the color blocks in the processing area are flattened according to the color block removal depth, so that the thickness of the area removed by the flattening operation reaches the color block removal depth.
[0181] By adopting the above technical solution, after obtaining the thickness distribution of the color block, the color block removal depth is generated, and the color block in the processing area is smoothed according to the color block removal depth to ensure the uniformity of the color block in the processing area, so that the lighting effect of the car knob light-emitting part is better and the uniformity of the lighting color is better.

This technical solution can thus form multiple layers of color blocks in the automotive knob light-emitting component, resulting in a better lighting effect and more uniform color.
