If broken holes occur, they can only be discovered during the back-end process, which will inevitably cause batch losses.

[0048] 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.

[0049] Inkjet printing technology is widely used in a variety of fields, including home and office inkjet printers, industrial applications, home decor and furniture, personalized gifts, digital products, films, games, animation, pop culture merchandise, and advertising and signage. Regardless of these application scenarios, inkjet printing uses inks with different compositions based on the specific process requirements. These compositions can damage the printhead over time, causing partial blockage of the printhead nozzles, resulting in skewed or no ink jetting. Alternatively, the ink used can be highly viscous, easily clogging the nozzles. Such nozzles are known as broken nozzles.

[0050] Broken holes will inevitably affect print quality, especially in industrial production, which is completely automated and unmanned. If broken holes occur, they can only be discovered during the back-end process, which will inevitably cause batch losses. Therefore, nozzle status detection is an important means to ensure smooth production.

[0051] Based on this, embodiments of the present application provide a method, apparatus, device, and medium for detecting the nozzle status of a printer, which are described below through embodiments.

[0052] Figure 1A flow chart of a method for detecting the nozzle status of a printer provided by an embodiment of the present application is shown, wherein the method includes steps S101-S103; specifically:

[0053] S101: For a target printer in a working stage, determining a detection condition of the target printer according to a printing process requirement of the target printer and a material property of a printing material used by the target printer;

[0054] S102: When the target printer meets the detection condition, control the target printer to print in a preset detection area, and obtain a first to-be-detected image of the printing result of the target printer in the detection area;

[0055] S103 : Determine a first abnormal nozzle in the target printer by analyzing the printing result in the first image to be detected.

[0056] This application can set corresponding detection conditions in accordance with the actual working state of the printer, and detect the printer based on the detection conditions, thereby ensuring the accuracy of the detection results.

[0057] The following describes some embodiments of the present application in detail. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0058] The present invention discloses a method for detecting the nozzle status of a printer, which is applied to a predetermined detection system. The detection system includes a mobile device, a camera device, and a processing device. The mobile device controls the movement of the printer's inkjet assembly, the camera device captures images, and the processing device processes the images.

[0059] In the embodiment of the present application, the printer that needs to be tested is referred to as a 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 described in detail 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 the embodiment of the present application refers to this stage as the test stage of the target printer. 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 testing stage. The working stage mainly uses the nozzle hole in normal state, and the abnormal nozzle hole is in the closed state. In the testing stage, all the nozzle holes are opened for printing, and all the nozzle holes are tested.

[0060] After determining the print job, the target printer can select the appropriate printing process and printing material based on the object to be printed. The printing process here includes the printing order and the area of ​​the printing material to be sprayed. For example, if the object to be printed is a rectangular parallelepiped, the printing process may include spraying the entire front surface of the rectangle first, then spraying half of the back surface, etc. The printing material here is primarily ink. Different printing inks have different properties, such as viscosity and surface tension.

[0061] After determining the printing process and printing materials of the target printer, the detection conditions of the target printer are determined based on the printing process requirements of the target printer and the material properties of the printing materials used by the target printer. In a 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. If the number of objects to be printed printed by the target printer does not reach the print quantity threshold, the printing service continues until the print quantity threshold is reached, and then the target printer is detected.

[0062] 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 taken into account, 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 introduced, 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 status of the nozzle on the premise that the target printer can meet the printing process requirements and ensure the printing effect.

[0063] Specifically, the embodiment of the present application determines the print quantity threshold of the target printer based on 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 amount of printing material used when printing a standard object to be printed, B is the total amount of printing material stored in the target printer, and the second impact weight = 1 / C; wherein C is the total amount of objects 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 between 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.

[0064] 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 not detected until the target printer reaches the adjusted print quantity threshold again. The specific adjustment is made based on the error size of the verification result. The larger the error, the larger the adjustment, and the smaller the error, the smaller the adjustment.

[0065] For example, if the print quantity threshold is 50, and the target printer prints 50 objects, the target printer is tested. After six first abnormal nozzles are detected, manual re-testing is performed to determine whether the first abnormal nozzles are truly abnormal. The verification result is that five are truly abnormal. In this case, the error is small, and the print quantity threshold does not need to be adjusted. If the verification result is that three are truly abnormal, the error is large, and the print quantity threshold needs to be adjusted. The adjusted print quantity threshold is 55.

[0066] In an optional embodiment, when the target printer meets the detection conditions, the detection of the target printer is to control the target printer to print in a preset detection area (including the base medium) through a mobile device, and use a shooting device to shoot a first image to be detected of the printing result of the target printer in the detection area, and by analyzing the printing result in the first image to be detected, the first abnormal nozzle in the target printer is determined.

[0067] The analysis process for the first image to be inspected includes comparing the first image to be inspected with a preset reference image to determine the presence, size, and position of ink droplets (printing material) in the first image to be inspected, and then determining whether the nozzle is in an abnormal state. Abnormal conditions include the absence of ink droplets, inappropriate size, and position deviation.

[0068] In an optional embodiment, after the target printer is detected once, in order to avoid missed detection, the embodiment of the present application needs to perform a second detection on the target printer. Figure 2 As shown, including S201-S203:

[0069] S201, when the target printer again meets the detection condition (or the adjusted 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;

[0070] S202, determining a second abnormal nozzle in the target printer by analyzing the printing result in the second image to be detected;

[0071] S203 : 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.

[0072] The specific detection process is the same as that in the above embodiment and will not be repeated here. The target judgment standard here is obtained by adjusting the initial judgment standard. The initial judgment standard is manually set. After the initial judgment standard is set, a print test is performed on the target printer to obtain the test results. The test here generally involves multiple prints. The accuracy of the initial judgment standard is determined by statistically analyzing the print results of each print. If the initial judgment standard is inaccurate, it is adjusted to obtain the adjusted target judgment standard.

[0073] For example, the initial judgment standard is based on the previous test results. By performing three prints on the target printer, the first print test revealed three abnormal nozzles (No. 1, No. 2, and No. 3), the second print test revealed three abnormal nozzles (No. 1, No. 2, and No. 4), and the third print test revealed four abnormal nozzles (No. 1, No. 2, No. 3, and No. 4). Therefore, the initial judgment standard needs to be adjusted to the combined results of the two tests.

[0074] In an optional embodiment, after detecting a target printer, abnormal nozzles (a first abnormal nozzle or a first abnormal nozzle and a second abnormal nozzle) are identified in the target printer. After the abnormal nozzles are identified, corresponding treatment measures need to be matched to the abnormal nozzles. These treatment measures include downtime alarms and compensation measures. The corresponding treatment measures are used to handle the abnormal nozzles.

[0075] When using compensation measures to process abnormal nozzles, normal nozzles corresponding to the abnormal nozzles are determined according to a preset compensation algorithm; and the normal nozzles are used to replace the corresponding abnormal nozzles for printing.

[0076] Specifically, the nozzles of each nozzle are evenly divided into multiple printing units (each printing unit includes only one abnormal nozzle), and from other units except the printing unit where the abnormal nozzle is located, a normal nozzle at a position corresponding to the abnormal nozzle is selected to replace the abnormal nozzle for printing.
