[0096] If the difference between the comprehensive quality evaluation coefficient and the average appearance quality coefficient is within a preset range, the enamel porcelain corresponding to the comprehensive quality evaluation coefficient is determined to be a qualified product;

[0097] If the difference between the comprehensive quality assessment coefficient and the average appearance quality coefficient is not within a preset range, the enamel porcelain corresponding to the comprehensive quality assessment coefficient is determined to be a product of unqualified quality.

[0098] As described in the above steps S1-S5, the existing product quality inspection of enamel colored porcelain is mainly carried out by quality inspectors to visually inspect the enamel colored porcelain and determine whether the enamel colored porcelain has defects. However, visual inspection is highly subjective and prone to missed detection and misjudgment. Therefore, the present application needs to obtain the appearance attribute characteristics of the surface of the enamel colored porcelain, wherein the appearance attribute characteristics include crack attribute information, bubble information and color difference information, so that the production quality of the enamel colored porcelain can be comprehensively judged according to the main characteristics of the surface of the enamel colored porcelain. The specific judgment steps are: first, the texture length information and texture depth information of the surface of the enamel colored porcelain are obtained according to the crack attribute information, so that after obtaining the texture length information and texture depth information, the surface of the enamel colored porcelain can be comprehensively judged. The texture condition is then calculated according to the texture length information and the texture depth information, so that the texture cracking coefficient of the enamel colored porcelain appearance can reflect the texture quality evaluation value of the enamel colored porcelain surface, and then the texture quality evaluation value can be used to preliminarily judge whether the texture of the enamel colored porcelain surface meets the production standard, and then the bubble position information and the bubble volume information of the enamel colored porcelain surface are obtained according to the bubble information, wherein the closer the bubble position is to the enamel filigree frame, the greater the impact on its quality, and the enamel filigree frame is a component for making enamel colored porcelain, and at the same time, the larger the bubble volume is, the greater the impact on the quality of the enamel colored porcelain, and then the bubble influence coefficient of the enamel colored porcelain appearance can be calculated according to the bubble position information and the bubble volume information. The calculated bubble influence coefficient can reflect the bubble evaluation value of the influence of bubbles on the surface of enamel colored porcelain on its quality. Then, the brightness information and hue information of the surface of enamel colored porcelain are obtained according to the color difference information. In this way, it can be judged whether there is color difference in enamel colored porcelain through the brightness information and hue information. At the same time, the color difference coefficient of the appearance of enamel colored porcelain can be calculated according to the brightness information and hue information. Then, the color difference coefficient can reflect the color difference evaluation value of the influence of the color difference on the surface of enamel colored porcelain on its quality. Then, the comprehensive quality evaluation coefficient of enamel colored porcelain is calculated according to the texture cracking coefficient, bubble influence coefficient and color difference coefficient. The comprehensive quality evaluation coefficient calculated in this way can reflect the product quality of enamel colored porcelain. Then, the surface of enamel colored porcelain is evaluated. Perform regional division to obtain multiple regional quality collection points, and extract appearance quality features from the multiple regional quality collection points based on a linear regression model to obtain multiple appearance quality coefficients, wherein the linear regression model mainly uses the standard parameters of enamel porcelain in history as independent variables, and the appearance quality coefficient as the dependent variable, and then adjusts the error between the independent variable and the dependent variable through the linear regression model, and predicts the quality value of the dependent variable through the independent variable to obtain multiple appearance quality coefficients, and obtains the appearance average quality coefficient based on the multiple appearance quality coefficients, and determines whether the difference between the comprehensive quality evaluation coefficient and the appearance average quality coefficient is within a preset interval. If the difference between the comprehensive quality evaluation coefficient and the appearance average quality coefficient is within the preset interval,The enamel colored porcelain corresponding to the comprehensive quality assessment coefficient is judged as a qualified product, otherwise, the enamel colored porcelain corresponding to the comprehensive quality assessment coefficient is an unqualified product. The product quality of the enamel colored porcelain can be judged by the specific value of the enamel colored porcelain, thereby avoiding the problems of missed detection and misjudgment caused by existing visual inspection.

[0104] S203, based on the acoustic wave scanner, multiple acoustic wave pulse signals are emitted to the multiple black stripes, and multiple rebound signals returned after the acoustic wave pulse signals hit the inner cavities of the multiple black stripes are received, multiple return distances from the acoustic wave scanner to the multiple black stripes are obtained according to the multiple rebound signals, and an average return distance is calculated according to the multiple return distances, and information corresponding to the average return distance is used as texture depth information.

[0105] As described in the above steps S201-S203, since the crack properties on the surface of enamel porcelain are important properties that determine the quality of enamel porcelain, based on this, the present application first obtains the surface image information of the enamel porcelain according to the crack property information, and grayscales the surface image information to obtain black and white surface image information. After the image is processed, black represents cracks, and the remaining white represents the filling color of the enamel polished surface. Then, a plurality of black stripes are screened out according to the black and white surface image information, and coordinates are respectively established for the two ends of each individual black stripe in the plurality of black stripes to obtain a plurality of first coordinates and a plurality of second coordinates, wherein the coordinates of the two ends of the selected black stripes are the coordinates with the farthest distance between them, and the crack lengths of the plurality of black stripes are calculated in sequence according to the plurality of first coordinates and the plurality of second coordinates, for example, the first coordinate is (2,1), and the second coordinate is (3,4). After calculating the crack length in this way, it is possible to determine the impact of the crack length on the product quality of enamel porcelain. Then, based on the acoustic wave scanner, multiple acoustic wave pulse signals are emitted to multiple black stripes, and multiple rebound signals returned after the acoustic wave pulse signals hit the inner cavity of the multiple black stripes are received. According to the multiple rebound signals, multiple return distances from the acoustic wave scanner to the multiple black stripes are obtained, and the average return distance is calculated based on the multiple return distances, and the information corresponding to the average return distance is used as texture depth information. After obtaining the texture depth information, it is possible to determine the impact of the crack length on the product quality of enamel porcelain again, and then use the texture length information and texture depth information to comprehensively reflect the impact of the crack on the product quality of enamel porcelain. The above-mentioned numbers are only used for illustration and are not the only reference.

[0112] As described in the above steps S204-S206, since the texture length information and the texture depth information can comprehensively reflect the impact of cracks on the product quality of the enamel colored porcelain, it is necessary to obtain the area of ​​the filled enamel area of ​​the enamel colored porcelain and the surface flatness of the enamel colored porcelain according to the texture length information, and obtain the smoothness of the enamel colored porcelain according to the area of ​​the filled enamel area of ​​the enamel colored porcelain and the surface flatness of the enamel colored porcelain. In this way, the smoothness of the enamel colored porcelain can be used to comprehensively judge whether there is protrusion on the surface texture of the enamel colored porcelain, and the protrusion will affect the quality of the enamel colored porcelain. Then, multiple texture crack widths of the enamel colored porcelain are obtained according to the texture depth information, and the texture crack width can reflect the degree of texture damage, and then the quality of the enamel colored porcelain is judged according to the texture crack width. After obtaining the smoothness, the area of ​​the filled enamel area and the multiple texture crack widths, the texture crack coefficient is calculated according to the smoothness, the area of ​​the filled enamel area and the multiple texture crack widths. In this way, the texture crack coefficient obtained can judge the impact of the texture crack on the product quality of the enamel colored porcelain.

The color difference coefficient calculated in this way can reflect the relationship between color difference and the quality of enamel porcelain in a numerical way, and then the quality of enamel porcelain can be comprehensively judged through the color difference coefficient.
