[0034] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further elaborates on the present application in conjunction with the appended Figure 1 to the appended Figure 9 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Automotive knob lighting components are widely used in various vehicles. Taking the application of an automotive knob lighting component on an air-conditioning knob as an example in the embodiment of the present application, the automotive knob lighting component includes a working mode and a closed mode. A lighting area is provided on the automotive knob lighting component, and the lighting area emits light in the working mode. Please refer to Figure 1 , the lighting area of the automotive knob lighting component includes area one 101, area two 102 and area three 103. When the automotive knob lighting component is in the working mode, area one 101 emits blue light, area two 102 emits white light, and area three 103 emits red light.

[0036] The embodiment of the present application discloses a manufacturing method for an automotive knob lighting component. Refer to Figure 2 , the method includes: Step S201: Determine a processing area on the processing surface of the transparent lighting component. The processing area includes 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 an annular segment, and the first area, the second area and the third area are connected in sequence in the clockwise direction.

[0037] The transparent lighting component is a colorless transparent or white transparent object. The shape of the transparent lighting component is the same as that of the automotive knob lighting component. Please refer to Figure 1 , the shape of the transparent lighting component is composed of two parts: a circular tubular component 11 located at the bottom and a circular disc-shaped component 10 located at the top. The radius of the circular disc-shaped component 10 is greater than or equal to the radius of the circular tubular component 11.

[0038] The processing surface is located on the circular disc-shaped component and is the side away from the circular tubular component. The processing area is a preset area on the processing surface, and the shape and position of the processing area depend on the lighting area of the automotive knob lighting component.

[0039] Step S202: Pad-print a first color block on the first area and pad-print a second color block on the second area. 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.

[0040] Pad printing is a technique for transferring printing paint, coating or ink, and can form color blocks with specific shapes in specific areas on the processing surface of the transparent lighting component.

[0041] Optionally, the first color patch is yellow and the second color patch is green.

[0042] Optionally, when the first color patch is pad-printed each time, a first transition area is provided at the edge of the first color patch. The first transition area surrounds the first color patch, and the thickness of the first transition area is less than the thickness of the first color patch.

[0043] Optionally, when the second color patch is pad-printed each time, a second transition area is provided at the edge of the second color patch. The second transition area surrounds the second color patch, and the thickness of the second transition area is less than the thickness of the second color patch.

[0044] The first preset thickness and the second preset thickness are preset empirical values, and those skilled in the art can adjust the specific values of the first preset thickness and the second preset thickness according to actual requirements. The first preset thickness and the second preset thickness may be the same or different.

[0045] Exemplarily, please refer to Figure 3 , first form the first color patch 31 on the processing surface, and then form the second color patch 32. A first transition area 311 is formed at the edge of the first color patch 31, and a second transition area 321 is formed at the edge of the second color patch 32.

[0046] Step S203: Pad-print a light-transmitting paint on the processing surface to form a primer layer, and the primer layer covers the processing surface.

[0047] The light-transmitting paint is a paint or ink with light-penetrating properties. In this application, on the one hand, the primer layer can include the first color patch and the second color patch in the subsequent processing process. On the other hand, the primer layer can adjust the color of the first color patch and the second color patch so that the light-emitting color of the final automotive knob light-emitting part meets the design standard.

[0048] Exemplarily, please refer to Figure 3 , pad-print a light-transmitting paint on the processing surface to form a primer layer 33.

[0049] Step S204: Pad-print a third color patch on the first area corresponding to the primer layer, and pad-print a fourth color patch on the third area corresponding to the primer layer.

[0050] Optionally, the third color patch is blue and the fourth color patch is red.

[0051] Exemplarily, please refer to Figure 3 , pad-print a third color patch 34 on the first area corresponding to the primer layer 31, and pad-print a fourth color patch 35 on the third area corresponding to the primer layer 31.

[0052] Step S205: Pad-print a light-shielding paint on the primer layer to form a protective paint layer.

[0053] The light-shielding paint is a paint or ink with high hiding power and low light transmittance, and is used to block the penetration of light. In this application, on the one hand, the light-shielding paint can protect the underlying third color block, fourth color block and primer layer, and on the other hand, the light-shielding paint can allow light to escape from specific areas.

[0054] Exemplarily, please refer to Figure 3 , and pad-print the light-shielding paint on the primer layer to form a protective paint layer 36.

[0055] Step S206: Perform a removal operation on the processing area corresponding to the protective paint layer to obtain an automotive knob lighting component.

[0056] Optionally, the removal operation is a laser removal operation.

[0057] Furthermore, different removal operations are used for different processing areas in this application. For the first area, perform a removal operation on the first area corresponding to the protective paint layer until the third color block is exposed. For the second area, perform a removal operation on the second area corresponding to the protective paint layer until the primer layer is exposed. For the third area, perform a removal operation on the third area corresponding to the protective paint layer until the fourth color block is exposed.

[0058] Exemplarily, please refer to Figure 3 , perform a removal operation on the processing area corresponding to the protective paint layer 36, expose the third color block 34 in the first area, expose the primer layer 33 in the second area, and expose the fourth color block 35 in the third area.

[0059] By adopting the above technical solution, processing areas are planned on the transparent lighting component, and different numbers and different colors of color blocks are added to different processing areas. Therefore, this technical solution can form multiple layers of color blocks in the automotive knob lighting component, making the lighting effect of the automotive knob lighting component better and the uniformity of the lighting color better.

[0060] In the following embodiments, after the first color block and the second color block are formed, in order to ensure the qualification of the first color block and the second color block, the first color block and the second color block need to be detected. The following embodiments take the detection of the first color block as an example for illustration. An embodiment of this application discloses a color block detection method. Refer to Figure 4 , the method includes: Step S401: Collect the discrete hue values at the detection points on the first color block.

[0061] The detection points are discrete points on the first color block. The positions of the detection points on the first color block can be preset or randomly generated.

[0062] The discrete hue value refers to the hue value at discrete points. The hue value is used to describe the basic attribute of a color. In this embodiment, the hue value refers to the degree mapped to the circular color wheel for a color. For example, red is 0 degrees, green is 120 degrees, and blue is 240 degrees.

[0063] Step S402: Calculate the variance of the discrete hue values to obtain the hue value variance.

[0064] The hue value variance is used to represent the degree of dispersion of the discrete hue values.

[0065] Step S403: When the hue value variance is less than the preset variance, calculate the mean value of the discrete hue values to obtain the first hue value.

[0066] The preset variance is a preset empirical value, and those skilled in the art can adjust the specific value of the preset variance according to actual needs.

[0067] On the other hand of this application, when 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 light-emitting effect of the automotive knob light-emitting component.

[0068] Step S404: Detect whether the first hue value is greater than the hue value lower limit and less than the hue value upper limit.

[0069] The hue value lower limit and the hue value upper limit are preset empirical values, and the hue value lower limit is less than the hue value upper limit.

[0070] Step S405: If not, adjust the thickness of the first color block according to the first hue value.

[0071] If the first hue value is less than the hue value lower limit or the first hue value is greater than the hue value upper limit, it indicates that the color corresponding to the first hue value has a too large gap from the design standard, which will cause the light-emitting color of the automotive knob light-emitting component to deviate seriously. Also, since the color of the paint / ink used for the first color block is fixed, after the first color block is pad-printed, the first hue value of the first color block depends on the thickness of the first color block. Therefore, this application will adjust the thickness of the first color block.

[0072] Step S406: If so, execute the subsequent steps.

[0073] If the first hue value is between the hue value lower limit and the hue value upper limit, it indicates that the color corresponding to the first hue value meets the design standard. Therefore, execute the subsequent steps S203 to S206.

[0074] It should be noted that the detection steps for the second color block are the same as those provided in this embodiment, and will not be elaborated here.

[0075] 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 light-emitting color of the automotive knob light-emitting part meets the design standard and has a better light-emitting effect.

[0076] In the following embodiments, if it is necessary to adjust the thickness of the first color block, the corresponding adjustment method needs to be adopted according to the actual thickness of the first color block. Therefore, an embodiment of the present application discloses a method for adjusting the thickness of a color block. Refer to Figure 5 , the method includes: Step S501: Obtain the standard thickness of the first color block.

[0077] The standard thickness is a preset thickness, which refers to the thickness of the first color block that meets the design standard under ideal conditions.

[0078] Step S502: Convert the first hue value into the thickness of the first color block to obtain the actual thickness.

[0079] 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 deeper the color of the first color block in the human eye. Exemplarily, in the hue-thickness database, the thickness corresponding to the first hue value is retrieved to obtain the actual thickness, where 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.

[0080] Step S503: When the standard thickness is greater than the actual thickness, calculate the difference between the standard thickness and the actual thickness to obtain the first thickness difference.

[0081] When the standard thickness is greater than the actual thickness, it means that the first color block is too thin and the thickness of the first color block needs to be increased in the subsequent steps.

[0082] Step S504: Perform pad printing on the first color block according to the first thickness difference.

[0083] Optionally, the thickness of the first color block after pad printing is controlled by adjusting the pad printing pressure value. In this step, it is necessary to control the ink thickness of the pad printing to be maintained at the first thickness difference. Exemplarily, in the 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, control the pad printing squeegee 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.

[0084] Step S505: When the standard thickness is less than the actual thickness, generate the hue value distribution of the first color block according to the discrete hue values.

[0085] When the standard thickness is less 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.

[0086] The hue value distribution is used to represent the correspondence between the hue values and positions on the first color block. Exemplarily, after obtaining the discrete hue values, a plane coordinate system is established, and the detection points are marked in the plane coordinate system. The discrete hue values are assigned to the detection points. According to the detection points and the discrete hue values, interpolation is performed on other coordinate points in the plane coordinate system to obtain the fitted hue values of other coordinate points. According to the discrete hue values and the fitted hue values, the hue value distribution is obtained.

[0087] Step S506: According to the hue value distribution, determine the area where the thickness is greater than the standard thickness on the first color block to obtain the processing area.

[0088] Since the hue value of the first color block is directly related to the thickness of the first color block, the hue value distribution can be converted into the thickness distribution of the first color block. According to the thickness distribution, the area greater than the standard thickness is determined to obtain the processing area.

[0089] Step S507: Calculate the difference between the actual thickness and the standard thickness to obtain the second thickness difference.

[0090] The second thickness difference refers to the difference between the actual thickness and the standard thickness.

[0091] Step S508: Perform a removal operation on the processing area according to the second thickness difference.

[0092] Optionally, the removal operation adopts a laser removal operation. Exemplarily, set the processing duration and laser power of the laser removal operation according to the second thickness difference. Perform the removal operation on the processing area according to the processing duration and laser power.

[0093] 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 obtained by converting according to the first hue value, and the actual thickness and the standard thickness are compared. According to the size relationship between the actual thickness and the standard thickness, the corresponding method is selected to adjust the thickness of the first color block, so as to ensure that the thickness of the first color block meets the requirements. Furthermore, the light-emitting color of the automotive knob lighting component conforms to the design standard and the light-emitting effect is better.

[0094] In the following embodiments, after performing the removal operation on the processing area corresponding to the protective paint layer, it is necessary to ensure that there is no residue of the light-shielding paint and no uneven color block situation in the processed processing area. Therefore, this application embodiment discloses a color block processing method one. Refer to Figure 6, the method includes: Step S601: Detect whether there is residual light-shielding paint in the processing area.

[0095] If there is residual light-shielding paint in the processing area, execute Step S602 to Step S603; If there is no residual light-shielding paint in the processing area, execute Step S604 to Step S606.

[0096] The residual light-shielding paint is the light-shielding paint remaining in the processing area corresponding to the protective paint layer.

[0097] Optionally, capture an image of the protective paint layer corresponding to the protective paint layer through a camera. 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, the residual light-shielding paint can be identified in the processing area corresponding to the light-shielding paint layer image using the color of the light-shielding paint layer.

[0098] Step S602: If so, obtain the residual position of the residual light-shielding paint.

[0099] The residual position refers to the position of the residual light-shielding paint in the processing area. Optionally, the residual position can be obtained through the image of the protective paint layer.

[0100] Step S603: Perform a removal operation on the residual light-shielding paint according to the residual position.

[0101] The removal operation can adopt a laser removal operation. Exemplarily, after obtaining the residual position, perform a laser removal operation on the residual light-shielding paint at the residual position, and obtain a real-time image of the residual position in real time. When it is detected that the residual light-shielding paint in the real-time image is completely removed, stop the laser removal operation.

[0102] Step S604: If not, obtain the transmitted color of the processing area.

[0103] The transmitted color refers to the color of the light after passing through the processing area. For the first area, the transmitted color refers to the color of the light after passing through the first color block, the primer layer, and the third color block; for the second area, the transmitted color refers to the color of the light after passing through the second color block and the primer layer; for the third area, the transmitted color refers to the color of the light after passing through the primer layer and the fourth color block.

[0104] Optionally, set test points in the processing area, where at least two test points are set in each area of the processing area. Obtain the transmitted color at the test points.

[0105] The transmitted color is represented by a hue value.

[0106] Step S605: Calculate the uniformity of the transmitted color.

[0107] The uniformity is used to describe the distribution consistency of the transmitted color within the processing area. Optionally, the mean value of the hue values corresponding to the transmitted color within the processing area is calculated to obtain a reference value. Based on the hue values corresponding to the transmitted color and the reference value, the color difference is calculated to obtain the uniformity.

[0108] In this step, it is necessary to calculate the uniformity of the transmitted color for each area in the processing area separately. For example, the transmitted color of the first area is obtained, and the uniformity corresponding to the first area is calculated based on the transmitted color of the first area.

[0109] Step S606: When the uniformity is greater than the uniformity threshold, perform a flattening operation on the color patches in the processing area.

[0110] When the processing area includes the first area, perform a flattening operation on the third color patch. When the processing area includes the second area, perform a flattening operation on the primer layer. When the processing area includes the third area, perform a flattening operation on the fourth color patch.

[0111] In another implementation manner of this embodiment, when the uniformity is not greater than the uniformity threshold, it indicates that the color distribution in the processing area is uniform and no other processing is required.

[0112] By adopting the above technical solution, when removing the light-shielding paint, it will detect whether there is residual light-shielding paint, judge whether the transmitted color in the processing area is uniform, and give corresponding treatment measures, so that the residual light-shielding paint is completely removed and the uniformity of the processing area is improved. Thereby enhancing the light-emitting effect of the automotive knob lighting component and ensuring the uniformity of its emitted light color.

[0113] In the following embodiments, a method for removing residual light-shielding paint will be disclosed to ensure the complete removal of the residual light-shielding paint. Therefore, the embodiments of the present application disclose a second color patch processing method. Refer to Figure 7 , this method includes: Step S701: According to the residual position, obtain the edge contour and the center position of the residual light-shielding paint.

[0114] The center position refers to the center of the minimum circumscribed rectangle of the residual light-shielding paint.

[0115] Optionally, in the protective paint layer image, perform edge detection on the area where the residual light-shielding paint is located to obtain the edge contour of the residual light-shielding paint.

[0116] Optionally, generate a minimum circumscribed rectangle according to the edge contour of the residual light-shielding paint. According to the position coordinates of the minimum circumscribed rectangle, obtain the center position.

[0117] Step S702: Calculate the distance from the edge contour to the center position to obtain the contour distance.

[0118] Optionally, take any point on the edge contour and obtain the point coordinates of the any point. According to the point coordinates and the central position, obtain the contour distance.

[0119] Step S703: Take the maximum value in the contour distances to obtain the maximum contour distance, and generate a target connection line corresponding to the maximum contour distance. The target connection line points from the edge contour to the central position.

[0120] Exemplarily, after determining the maximum contour distance, obtain the edge contour point corresponding to the maximum contour distance. Make a directed line segment from the edge contour point to the central position to obtain the target connection line.

[0121] Step S704: Perform a removal operation on the residual light-shielding paint along the target connection line to obtain the remaining situation of the residual light-shielding paint.

[0122] The removal operation can adopt a laser removal operation. Exemplarily, after obtaining the target connection line, use the starting point of the target connection line as the starting point of the laser removal operation and the end point of the target connection line as the end point of the laser removal operation to perform a laser removal operation on the residual light-shielding paint. At the same time, obtain a real-time image of the residual position in real time. Obtain the remaining situation of the residual light-shielding paint according to the real-time image.

[0123] Step S705: If the remaining situation indicates that the residual light-shielding paint is not completely removed, repeat the above four steps.

[0124] If the remaining situation indicates that the residual light-shielding paint is not completely removed, repeat steps S701 to S704 above to re-perform a removal operation on the residual light-shielding paint.

[0125] Step S706: If the remaining situation indicates that the residual light-shielding paint is completely removed, perform subsequent steps.

[0126] If the remaining situation indicates that the residual light-shielding paint is completely removed, it can be considered that the automotive knob lighting component has reached the factory standard.

[0127] By adopting the above technical solution, set the target connection line according to the shape and position of the residual light-shielding paint, and perform removal on the residual light-shielding paint along the target connection line, so as to improve the removal rate of the residual light-shielding paint and ensure the lighting effect and color uniformity of the automotive knob lighting component.

[0128] In the following embodiments, a method for flattening the color blocks in the processing area will be disclosed to ensure complete removal of the residual light-shielding paint. Embodiment of the present application discloses a third color block processing method. Refer to Figure 8 , the method includes: Step S801: Obtain the second hue value corresponding to the transmitted color.

[0129] The second hue value refers to the hue value of the transmitted color.

[0130] Step S802: Convert the second hue value into the thickness of the color patches in the processing area to obtain a thickness distribution.

[0131] The thickness distribution is used to describe the thickness of the color patches in the processing area at different positions.

[0132] Exemplarily, in the hue-thickness database, retrieve the thickness corresponding to the second hue value to obtain the thickness of the color patches in the processing area, where the hue-thickness database is used to record the mapping relationship between the hue value and the thickness of the color patches, and the data in the hue-thickness database can be obtained by technicians through repeated experiments.

[0133] Step S803: Generate the color patch removal depth according to the thickness distribution.

[0134] Exemplarily, calculate the thickness average value according to the thickness distribution and set the thickness average value as the color patch removal depth.

[0135] Step S804: Perform a flattening operation on the color patches in the processing area according to the color patch removal depth.

[0136] The flattening operation adopts mechanical polishing treatment. Exemplarily, perform a flattening operation on the color patches in the processing area according to the color patch removal depth, so that the removed thickness of the flattening operation reaches the color patch removal depth.

[0137] By adopting the above technical solution, after obtaining the thickness distribution of the color patches, generate the color patch removal depth, and perform a flattening operation on the color patches in the processing area according to the color patch removal depth, ensuring the uniformity of the color patches in the processing area, making the light-emitting effect of the automotive knob light-emitting part better and the uniformity of the light-emitting color better.

Therefore, this technical solution can form multiple layers of color patches in the automotive knob light-emitting part, making the light-emitting effect of the automotive knob light-emitting part better and the uniformity of the light-emitting color better.
