[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is: obtaining coating information of the target workpiece, and determining coating composition information and coating thickness information based on the coating information; checking the current state of the target workpiece based on the coating composition information and the coating thickness information; and determining whether the target workpiece meets safety conditions based on the inspection results.

[0053] In this embodiment, for the convenience of description, the following description is made by taking the identification of coating inspection equipment as the execution subject.

[0054] Due to the existing technology, various types of magnesium, aluminum and other materials are widely used in various types of high-precision machinery or equipment, but the corrosion resistance of workpieces made of such metals is not good. In order to overcome this problem, the current means is to spray a protective layer on the metal workpiece to prevent corrosion. However, the widely used ceramic coatings also have defects or other flaws, so it is necessary to conduct sampling inspections on each batch of plated workpieces. At present, the monitoring of the coating is limited to monitoring the equipment on the production line, and the coating quality of the workpiece itself cannot be analyzed.

[0055] The present application provides a solution, through which the coating information of the target workpiece is pre-set, and then the specific composition, thickness and other parameter information of the coating of the target workpiece in the design stage is determined based on the coating information, and then the state of the coating of the target workpiece at the current moment is inspected based on the pre-designed specific composition and thickness, so that the coating of the target workpiece can be judged for safety based on the inspection results to determine whether the safety conditions are met, thereby achieving a more comprehensive and accurate analysis of the coating condition of the workpiece.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a server, etc. that can realize the above functions. The following takes the coating inspection equipment as an example to illustrate this embodiment and the following embodiments.

[0057] Based on this, the present application embodiment provides a coating inspection method, referring to Figure 1 , Figure 1 This is a schematic flow chart of the first embodiment of the coating inspection method of the present application.

[0058] In this embodiment, the coating inspection method includes steps S10 to S40:

[0059] Step S10, obtaining coating information of the target workpiece, and determining coating composition information and coating thickness information according to the coating information;

[0060] It should be noted that the target workpiece can be a workpiece of any size and shape, and this embodiment is not limited to this. First, the coating information of the target workpiece is obtained, that is, the relevant settings of the coating that needs to be completed on the target workpiece determined in the production or design stage, which may include but are not limited to the material, thickness, quantity, etc. of the coating.

[0061] It should be understood that the coating composition information refers to information related to the composition materials of each layer of coating in the design stage of the target workpiece, and the coating thickness information refers to setting information of the coating thickness of different coatings.

[0062] In a feasible implementation manner, in order to accurately determine the coating composition information and the coating thickness information, the step of determining the coating composition information and the coating thickness information according to the coating information includes: determining the coating spraying information during the production of the target workpiece according to the coating information; determining the coating paint information and the preset spraying strategy according to the coating spraying information; determining the coating composition information according to the coating paint information; and determining the coating thickness information according to the preset spraying strategy.

[0063] In a specific implementation, firstly, the coating spraying information set for the target workpiece during production is determined based on the coating information, that is, the information related to the setting parameters of the coating set by the equipment for spraying the protective layer, and then the coating coating information and the preset spraying strategy are determined based on the coating spraying information, wherein the coating coating information refers to the chemical formula, material composition and other related information of the coating coating, so that the coating composition information can be determined based on the coating coating information. The preset spraying strategy refers to the information such as the spraying time of the spraying equipment set to spray on the target workpiece, so that the final coating thickness information can be determined.

[0064] Step S20, checking the current state of the target workpiece according to the coating composition information and the coating thickness information;

[0065] It should be noted that after determining the coating composition information and coating thickness information, the coating composition information and coating thickness information are used as inspection benchmarks, and then the coating state of the target workpiece at the current moment is compared with the inspection benchmark to obtain the inspection result of the current state of the target workpiece.

[0066] Step S30: determining whether the target workpiece meets the safety condition according to the inspection result.

[0067] It should be understood that after obtaining the inspection results, the coating defect information of the target workpiece can be determined based on the data differences in the inspection results, so as to determine whether the target workpiece meets the safety conditions. The safety conditions refer to the minimum parameter range of the parameters of the coating of the target workpiece. If the parameter range exceeds the minimum limit, it is determined that the safety conditions are not met, and if the parameter range does not exceed the minimum limit, it is determined that the safety conditions are met.

[0068] In a feasible implementation manner, in order to accurately determine whether the target workpiece meets the safety conditions, step S30 includes: determining the coating deviation information of the target workpiece according to the inspection result; determining the deviation coating composition and the deviation spray thickness according to the coating deviation information; determining the interlayer continuous growth information based on the deviation coating composition and the deviation spray thickness; determining the coating defect information based on the interlayer continuous growth information, and the coating defect information includes interface defect information, interlayer gap information and coating uniformity information; comparing the coating defect information with the safety requirements of the target workpiece, and determining whether the target workpiece meets the safety conditions based on the comparison result.

[0069] In the specific implementation, the coating deviation information of the target workpiece is first determined according to the inspection results. The coating deviation information includes the deviation between the current coating of the target workpiece and the design standard. Then the coating deviation information is split to obtain the deviation coating composition and deviation spray thickness.

[0070] It should be noted that the inherent growth characteristics of ceramic coatings make it easy for interlayer continuous growth defects to occur between coatings of the same element. The interlayer continuous growth defects provide corrosion channels for corrosive media, which greatly limits the anti-corrosion performance of gradient multilayer coatings. Therefore, the interlayer continuous growth information is determined based on the deviation coating thickness and the deviation spraying thickness, so that the coating defect information can be determined.

[0071] It should be understood that the coating defect information includes interface defect information, interlayer gap information and coating uniformity information, among which interface defect information refers to cracks on the interface: if the thermal expansion coefficients between two adjacent layers are very different, or if the shrinkage is inconsistent during the cooling process, cracks may occur at the interface, which will reduce the mechanical strength of the coating and may become a path for the penetration of corrosive media. It may also be delamination (stratification): when the interlayer bonding force is insufficient, the coating is prone to delamination. This may be caused by contamination during the deposition process, improper surface treatment of the substrate, or poor chemical compatibility between coating materials. Interlayer gap information refers to the formation of pores or voids between layers during the coating preparation process if the gas is not discharged well or the material is unevenly distributed. These defects will affect the density and protective performance of the coating. Coating uniformity information means that the surface quality of each layer will affect the deposition effect of the subsequent layer. If the surface of the previous layer is not smooth enough or there is unevenness, it will be difficult for the next layer to obtain ideal continuity and flatness.

[0072] In a specific implementation, after obtaining the coating defect information, the coating defect information is compared with the safety requirements of the target workpiece, so as to determine whether the coating defects of the current target workpiece are within the requirements of safe production, thereby determining whether the target workpiece meets the safety conditions.

[0073] This embodiment provides a coating inspection method, which obtains the coating information of the target workpiece, and determines the coating composition information and coating thickness information according to the coating information; inspects the current state of the target workpiece according to the coating composition information and the coating thickness information; and determines whether the target workpiece meets the safety conditions according to the inspection results. In this way, it is realized based on the coating information of the pre-set target workpiece, and then determines the specific composition and thickness and other parameter information of the coating of the target workpiece in the design stage according to the coating information, and then inspects the state of the coating of the target workpiece at the current moment based on the pre-designed specific composition and thickness, so that the coating of the target workpiece can be safely judged according to the inspection results to determine whether the safety conditions are met, and a more comprehensive and accurate analysis of the coating condition of the workpiece is achieved.

[0074] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S20 includes steps S201 to S203:

[0075] Step S201, obtaining cross-sectional image information of the target workpiece;

[0076] It should be noted that firstly, the cross-sectional image information of the target workpiece is obtained. The specific means may be to shoot the cross-section of the target workpiece by a video acquisition device, or other imaging devices, which is not limited in this embodiment.

[0077] Step S202, performing image recognition on the cross-sectional image information to obtain a recognition result;

[0078] It should be understood that after the cross-sectional image information is obtained, image recognition is performed on the cross-sectional image information to determine the color, boundary line and other related image recognized information to determine the recognition result.

[0079] In a feasible implementation, in order to accurately perform image recognition, step S202 includes: performing image recognition on the cross-sectional image information to obtain cross-sectional color information; determining coating boundary line information and cross-sectional color sorting information based on the cross-sectional color information; and determining the recognition result based on the coating boundary line information and the cross-sectional color sorting information.

[0080] In a specific implementation, the cross-sectional image information is first directly subjected to image recognition to obtain the cross-sectional color information, and then the coating boundary line information is determined based on the cross-sectional color information. That is, the boundary between adjacent color blocks is determined based on the cross-sectional color information as the coating boundary line. When determining the sorting relationship of coatings of different colors, the sorting order can be from outside to inside or from inside to outside.

[0081] It should be noted that after the coating boundary line and the cross-section color sorting are determined, the final recognition result is determined based on the coating boundary line and the cross-section color sorting.

[0082] In a feasible implementation, in order to accurately determine the recognition result based on the color and the boundary line, the step of determining the recognition result based on the coating boundary line information and the cross-section color sorting information includes: determining the boundary line interval distance based on the coating boundary line information; determining the current coating thickness based on the boundary line interval distance; querying a preset component color comparison table based on the cross-section color sorting information to obtain the current cross-section coating component information; determining the recognition result based on the current coating thickness and the current cross-section coating component information.

[0083] It should be understood that the boundary line spacing distance, that is, the distance between every two adjacent boundary lines is first determined according to the coating boundary line information, and then the thickness of the coating material between every two boundary lines is determined based on the boundary line spacing distance.

[0084] In a specific implementation, the cross-section color sorting information is queried against a preset component comparison table, so that the components corresponding to each coating in the cross-section of the current target workpiece can be determined based on the color and sorting of the cross-section, wherein the preset component color comparison table refers to a pre-set comparison table in which the color characteristics of the coating on the cross-section correspond to different coating components.

[0085] It should be understood that if Figure 3 Shown is a schematic representation of a cross section, in which the different coatings have different colors, so that a color distinction can be obtained, and the distances between the individual dividing lines are also different.

[0086] It should be noted that after obtaining the current coating thickness and the current cross-section coating composition information, the final recognition result can be obtained, that is, the coating state information of the target workpiece after the coating is completed at the current moment.

[0087] Step S203 : checking the current state of the target workpiece according to the recognition result, the coating composition information and the coating thickness information.

[0088] It should be understood that after obtaining the recognition result, the coating state information after the coating is completed at the current moment in the recognition result is compared with the standard quantities set in the design and production stage to determine the current state of the target workpiece.

[0089] This embodiment obtains cross-sectional image information of the target workpiece; performs image recognition on the cross-sectional image information to obtain a recognition result; and checks the current state of the target workpiece according to the recognition result, the coating composition information, and the coating thickness information. In this way, the coating state of the target workpiece is recognized by means of image recognition, making subsequent coating detection more accurate.

[0090] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the coating inspection method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

In this way, it is realized that based on the pre-set coating information of the target workpiece, the specific composition and thickness and other parameter information of the coating of the target workpiece in the design stage are determined based on the coating information, and then the state of the coating of the target workpiece at the current moment is inspected based on the pre-designed specific composition and thickness, so that the coating of the target workpiece can be safely judged according to the inspection results to determine whether the safety conditions are met, thereby achieving a more comprehensive and accurate analysis of the coating condition of the workpiece.
