It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

[0049] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0050] Inkjet printing technology is widely used in many fields, including home and office inkjet printer products, industrial applications, home decoration and furniture, personalized gifts, digital products, movies, games, animation, pop culture products, and advertising and signage production. Regardless of the above application scenarios, in inkjet printing, different components of ink are used according to different process requirements. These components may damage the nozzles after long-term use, causing partial blockage of the nozzle holes of the print head, slanted spraying or no ink spraying; or the ink used is relatively viscous and easily clogs the nozzle holes. Such nozzle holes are called broken holes.

[0051] In the prior art, the nozzle orifice status detection usually adopts the method of advance detection. Before formal printing, one method is to detect the status of the nozzle orifice of the nozzle, before the ink droplets from the nozzle fall on the medium, dynamically detect the shape of the ink droplets, so as to judge the nozzle orifice status of the nozzle; another method is to observe the shape of the ink droplets on the medium after the ink droplets from the nozzle fall on the medium, so as to manually judge the nozzle orifice status of the nozzle. Regardless of which method is used, the efficiency is low; moreover, it can only be performed before formal production, and problems in production cannot be judged, and manual intervention is required to know, which not only increases labor costs, but also defective products will flow into the back-end production line, causing mass production accidents, leading to unpredictable economic losses.

[0052] Based on this, the embodiments of the present application provide a method, device, electronic device and storage medium for detecting the state of a nozzle, which are described below through embodiments.

[0053] Figure 1 A schematic flow chart of a method for detecting a nozzle state provided in an embodiment of the present application is shown, wherein the method comprises steps S101-S103; specifically:

[0054] S101, when a target printer completes one printing in a printing area, obtaining a first image to be detected of a printing result of the target printer in the printing area, and obtaining a first abnormal nozzle by detecting the first image to be detected;

[0055] S102, when the target printer meets the preset detection condition, controlling the target printer to print in a preset detection area, and obtaining a second image to be detected of the printing result of the target printer in the detection area, and obtaining a second abnormal nozzle by detecting the second image to be detected;

[0056] S103: Perform a comprehensive judgment on the first abnormal nozzle and the second abnormal nozzle using a preset target judgment standard to determine a target abnormal nozzle of the target printer.

[0057] This application uses different detection methods to detect the nozzles of the target printer, ensuring the accuracy of the detection results and improving the detection efficiency.

[0058] Some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0059] The embodiment of the present application discloses a method for detecting the state of a printer nozzle, which is applied to a preset detection system. The detection system here includes a moving device, a shooting device and a processing device. Among them, the moving device can control the inkjet component of the printer to move, the shooting device can perform image acquisition, and the processing device can perform image processing.

[0060] In the embodiment of the present application, the printer that needs to be tested is called the target printer, and the target printer includes multiple nozzles and corresponding multiple nozzle holes. The specific structure and principle of the target printer are relatively mature technologies in the prior art and will not be repeated here. In the embodiment of the present application, the target printer includes multiple different stages. For example, before the target printer leaves the factory, the target printer will be functionally tested, and this stage is called the test stage of the target printer in the embodiment of the present application. After the target printer leaves the factory, it will be placed in a preset working area to perform printing work. When the target printer performs printing work, it is called the working stage. During operation, there may be an abnormality in the nozzle hole, and the nozzle hole needs to be tested. This stage is called the detection stage. The working stage mainly uses the nozzle holes in the normal state, and the abnormal nozzle holes are in the closed state. In the detection stage, all the nozzle holes are opened for printing, and all the nozzle holes are tested.

[0061] In order to more accurately detect the nozzle of the target printer, the embodiment of the present application provides a method for monitoring the nozzle status, which mainly detects the target printer in two different stages. Among them, the first stage is when the target printer completes a print in the printing area, that is, after the target printer prints an object to be printed in the printing area. The printing area here is the normal working area of ​​the printer itself. The second stage is when the target printer meets the preset printing conditions.

[0062] In specific implementation, the detection condition here is a print quantity threshold. The print quantity threshold represents the maximum number of objects to be printed that the target printer can print. When the number of objects to be printed printed by the target printer reaches the print quantity threshold, the target printer is detected. When the number of objects to be printed printed by the target printer does not reach the print quantity threshold, the printing business continues until the print quantity threshold is reached, and the target printer is detected.

[0063] When determining the print quantity threshold, the embodiment of the present application fully considers the printing process requirements and the material properties of the printing materials. For different printing process requirements, the amount of printing materials used is different. If the amount of printing materials used is not considered, after printing for a long time, there will be a phenomenon of empty printing without ink. In this case, for the evaluation of the nozzle, interference factors are brought, and it is impossible to determine whether the nozzle is actually abnormal. Similarly, for different printing materials, due to different properties, the number of printing effects that can be guaranteed is also different. Therefore, in order to ensure the accuracy of the nozzle result detection, the embodiment of the present application needs to eliminate factors that are not conducive to detection. That is, the embodiment of the present application detects the state of the nozzle on the premise that the target printer can meet the printing process requirements and ensure the printing effect.

[0064] Specifically, the embodiment of the present application determines the print quantity threshold of the target printer according to the usage threshold (corresponding to the first quantity threshold) and the printing effect threshold (corresponding to the second quantity threshold). When determining the print quantity threshold, the embodiment of the present application also needs to determine the first impact weight of the usage threshold and the second impact weight of the printing effect threshold. For example, the first impact weight = A / B; wherein A is the usage of the printing material when printing a standard object to be printed, B is the total amount of printing materials stored in the target printer, and the second impact weight = 1 / C; wherein C is the total amount of the object to be printed that can be supported under the material properties. If the difference between the first impact weight and the second impact weight is large (the difference between the two is greater than the preset difference threshold), the smaller threshold of the first quantity threshold and the second quantity threshold is used as the print quantity threshold. If the difference between the first impact weight and the second impact weight is small (the difference between the two is less than or equal to the preset difference threshold), the average of the first quantity threshold and the second quantity threshold is used as the print quantity threshold.

[0065] After determining the print quantity threshold, the number of objects to be printed printed by the target printer is detected, and when the print quantity threshold is reached, the target printer is detected. After the detection, the first abnormal nozzle in the target printer is obtained. Furthermore, in order to ensure the accuracy of the detection result, after obtaining the first abnormal nozzle, the embodiment of the present application also needs to verify the first abnormal nozzle to obtain a verification result. The verification result is judged, that is, it is determined whether the print quantity threshold is really appropriate. If the print quantity threshold is not appropriate, the print quantity threshold needs to be adjusted to obtain the adjusted print quantity threshold. The target printer is detected only when the target printer reaches the adjusted print quantity threshold again. The specific adjustment is made according to the error size of the verification result. The larger the error, the larger the adjustment, and the smaller the error, the smaller the adjustment.

[0066] In the first stage, the embodiment of the present application obtains the first image to be detected of the target printer's printing result in the printing area. That is, the object to be printed printed by the target printer is photographed to obtain the first image to be detected. In the second stage, the embodiment of the present application obtains the second detection image of the target printer's printing result in the detection area. The first image to be detected and the second image to be detected are analyzed respectively to determine the first abnormal nozzle included in the first image to be detected and the second abnormal nozzle included in the second image to be detected. The analysis process of the first image to be detected includes constructing a reference coordinate system in the printing area; recording the printing coordinates of each nozzle in the reference coordinate system during the process of the target printer printing in the printing area; when the target printer completes one printing in the printing area, obtaining the first image to be detected of the target printer's printing result in the printing area; and determining the first abnormal nozzle according to the printing coordinates corresponding to the abnormal area in the first image to be detected.

[0067] like Figure 2 As shown, the graphics to be printed in the printing area of ​​the target printer are an ellipse. During the printing process, due to the existence of abnormal nozzle holes, the printed ellipse is not closed. In order to determine the first abnormal nozzle hole in the target printer, the embodiment of the present application constructs a reference coordinate system on the original printing area. The printing area is a rectangle, and the reference coordinate system uses the straight line where the long side of the printing area is located as the X-axis, and the straight line where the wide side of the printing area is located as the Y-axis. When the target printer is printing, it records the printing coordinates of the corresponding positions of the nozzle holes. After taking a first image to be detected in the printing area, the abnormal area in the first image to be detected is determined by detecting the image. The nozzle holes corresponding to the printing coordinates corresponding to the abnormal area are determined, and these empty nozzles are positioned as the first abnormal nozzle holes.

[0068] When analyzing the first image to be detected, the abnormal area in the first image to be detected is determined. In the specific implementation, the abnormal area may exist or not exist: point-shaped MURA and linear MURA. Based on this, the embodiment of the present application divides the types of abnormal areas into linear types and other types. Among them, the linear type only includes linear MURA, and the other types are types other than the linear type. When analyzing the first image to be detected, the embodiment of the present application only considers the linear type. That is, by detecting the first image to be detected, when the first image to be detected is of a linear type, the printing coordinates corresponding to the abnormal area are determined. Then, based on the relationship between the recorded coordinates and the nozzle, the first abnormal nozzle is deduced.

[0069] The analysis process of the second image to be detected includes comparing the second image to be detected with a preset reference image, determining the presence, size, position information, etc. of ink droplets (printing materials) in the second image to be detected, and then determining whether the nozzle is in an abnormal state. The abnormal state includes no ink droplets, inappropriate size, position offset, etc.

[0070] After the first abnormal nozzle and the second abnormal nozzle are determined through two tests, a preset target determination standard is used to perform a comprehensive determination on the first abnormal nozzle and the second abnormal nozzle to determine a target abnormal nozzle of the target printer.

[0071] The target judgment standard here is obtained by adjusting the initial judgment standard. The initial judgment standard is set manually. After setting the initial judgment standard, the test result is obtained by printing test on the target printer. The test here is generally multiple printings. The accuracy of the initial judgment standard is determined by statistically analyzing the printing results each time. When the initial judgment standard is inaccurate, it is adjusted to obtain the adjusted target judgment standard.

[0072] For example, the initial judgment standard is based on the previous test results. By printing the target printer three times, the first print test obtained three (No. 1, No. 2 and No. 3) abnormal nozzles, the second print test obtained three (No. 1, No. 2 and No. 4) abnormal nozzles; the third print test obtained four (No. 1, No. 2, No. 3 and No. 4) abnormal nozzles. Therefore, it is necessary to adjust the initial judgment standard to be based on the combination of the two tests.

[0073] In an optional embodiment, an abnormal nozzle (a first abnormal nozzle or a first abnormal nozzle and a second abnormal nozzle) included in the target printer is determined. After the abnormal nozzle is determined, a corresponding treatment measure needs to be matched for the abnormal nozzle. The treatment measures here include downtime alarm and compensation measures, etc. The abnormal nozzle is processed using the corresponding treatment measures.

[0074] When using compensation measures to process abnormal nozzles, target normal nozzles corresponding to each target abnormal nozzle are determined according to a preset compensation algorithm; and the target normal nozzles are used to replace the corresponding target abnormal nozzles for printing.

[0075] When determining the target normal nozzle hole, the operation steps required when the normal nozzle hole replaces the abnormal nozzle hole are mainly considered, and the normal nozzle hole with fewer operation steps is selected as the target normal nozzle hole of the target abnormal nozzle hole. The target normal nozzle hole is used to replace the corresponding target abnormal nozzle hole for printing.
