Description

Technical Field

[0001] The present application relates to the field of inkjet printing, and particularly to a method and device for adjusting the splicing position of nozzles, an electronic device, and a storage medium. Background Art

[0002] With the rise of the wide-format inkjet printing market, wide-format inkjet printing devices have become the mainstream. Since the width of a single inkjet print head is often narrow, a large number of nozzles need to be spliced for each color in a wide-format inkjet printing device. To prevent misalignment in printing at the splicing position after multiple nozzles are spliced and the printed image is not parallel to the moving direction of the paper, a bottom plate device with adjustable position is usually set at the part where the nozzle is fixed. However, most current inkjet printing devices use a manual method to adjust the nozzle position to obtain a better printing effect. However, manually adjusting the bottom plate according to the test sample will cause errors, and multiple test samples need to be printed and finely adjusted multiple times. Subjectively judging whether the nozzle bottom plate is accurately adjusted not only affects the efficiency but also cannot guarantee a good effect. Summary of the Invention

[0064] At present, wide-format inkjet printing devices have become the mainstream. In wide-format inkjet printing devices, a large number of nozzles need to be spliced for each color. At the position where the nozzles are fixed, people usually set a bottom plate 100 device with adjustable position to avoid uneven printing at the splicing position after multi-nozzle splicing, and the printed image is not parallel to the paper movement direction; however, this adjustable device usually requires manual adjustment, and subjective judgment is needed to determine whether it has been accurately adjusted. This method takes a lot of time, has low adjustment efficiency, and may still have deviations after adjustment, resulting in poor inkjet effects.

[0065] Based on this, the present application proposes a method, device, electronic device and storage medium for adjusting the splicing position of nozzles, aiming to achieve automatic fine-tuning of the nozzle assembly, improve efficiency while reducing labor costs, and also make the adjustment of the nozzles more accurate.

The adjustment module includes a first adjustment component and a second adjustment component, the first adjustment component includes a first driving member 140 and a first push block 141, the first driving member 140 is connected to the first push block 141, and the side wall of the first push block 141 is against the side wall of the first protrusion 121, the second adjustment component includes a second driving member 150 and a second push block 151, the second driving member 150 is connected to the second push block 151, the side wall of the second push block 151 is against the side wall of the second protrusion 131, and the side wall of the second push block 151 is also against the side wall of the third protrusion 132; the second nozzle assembly 110 is connected to the bottom plate 100 through the third spring, and the second nozzle assembly 1 A first connecting plate 120 and a second connecting plate 130 are provided on opposite sides of 10, a first mounting plate 101 is provided on the first connecting plate 120, a second mounting plate 102 is provided on the second connecting plate 130, a first convex portion 121 is provided on the first mounting plate 101, a second convex portion 131 and a third convex portion 132 are provided on the second mounting plate 102; a first fixing frame 160 is provided on the bottom plate 100, the first driving member 140 and the first pushing block 141 are connected by a first connecting rod, the first connecting rod shell is movably penetrated in the first fixing frame 160, and the first fixing frame 160 is connected to the first mounting plate 101 by a first spring 162 and a second spring 161. The first driving member 140 is used to drive the first push block 141 to move in the vertical direction after receiving the first offset, so that the first protrusion 121 drives the second nozzle assembly 110 away from or close to the side where the first protrusion 121 is provided. The second driving member 150 is used to drive the second push block 151 to move in the vertical direction after receiving the second offset, so that the second protrusion 131 and the third protrusion 132 drive the second nozzle assembly 110 away from or close to the first push block 141, thereby realizing fine-tuning operation of the second nozzle assembly 110.

[0067] The first embodiment of the present application is based on Figure 4 The inkjet printing device shown in the figure provides a method for adjusting the nozzle joint position. Figure 1 , Figure 1 This is a flow chart of the steps of the nozzle splicing position adjustment method according to an embodiment of the present application. Figure 1 The illustrated process steps include but are not limited to steps S101 to S106.

[0068] Step S101, controlling the first nozzle assembly and the second nozzle assembly to alternately perform inkjet operation on a test sample to obtain a test sample with ink marks.

[0069] Step S102: Perform image recognition on the ink marks on the test sample sheet with ink marks to obtain a first image.

[0070] Step S103: Preprocess the first image to obtain a second image.

[0071] Step S104: Obtain a first ink line and a second ink line based on the second image; wherein, the first ink line is formed by inkjet printing of the first printhead assembly, and the second ink line is formed by inkjet printing of the second printhead assembly.

[0072] Step S105: Calculate an offset based on the first ink line and the second ink line.

[0073] Step S106: In the case where the detected offset is a non-zero value, control the adjustment module to adjust the position of the second printhead assembly based on the offset.

[0074] Steps S101 to S106 shown in the embodiments of the present application alternately perform inkjet operations on the test sample sheet by the spliced first printhead assembly 170 and second printhead assembly 110 to generate ink marks for subsequent judgment; preprocessing the first image facilitates more accurately collecting the image contour on the first image, while eliminating unnecessary elements on the first image, making the memory occupied by the second image smaller, and thus making the processing more efficient. By obtaining the first ink line 210 and the second ink line 220 to judge the splicing position of the first printhead assembly 170 and the second printhead assembly 110, the calculation of the offset facilitates the first driving member 140 and the second driving member 150 to adjust the position of the printhead assembly according to the offset, thereby realizing automatic fine adjustment of the printhead assembly.

[0075] According to the printhead splicing position adjustment method of the embodiments of the present application, it has at least the following beneficial effects: First, perform inkjet operations on the test sample sheet by the first printhead assembly 170 and the second printhead assembly 110 to be adjusted. After recognizing and collecting the ink marks on the test sample sheet, perform preprocessing to obtain a second image, and obtain the first ink line 210 and the second ink line 220 in the second image. Among them, the first ink line 210 is formed by inkjet printing of the first inkjet assembly, and the second ink line 220 is formed by inkjet printing of the second inkjet assembly. Calculate the offset according to the first ink line 210 and the second ink line 220. When the offset is non-zero, control the adjustment module to adjust the second printhead assembly 110 according to the offset. In this way, there is no need for manual adjustment, realizing automatic fine adjustment of the spliced printheads, improving the efficiency and reducing the labor cost at the same time.

[0076] In step S101 of some embodiments, refer to Figure 10, the test sample is set on the conveyor belt, and the conveyor belt is arranged on the operating table. Before the first nozzle assembly 170 and the second nozzle assembly 110 are ready to perform the inkjet operation, the operating table will be started, thereby driving the conveyor belt to move in the first direction, and the conveyor belt will drive the test sample to move in the first direction. The first nozzle assembly 170 and the second nozzle assembly 110 perform the inkjet operation on the test sample according to a preset time interval. The specific operation is as follows: As the conveyor belt drives the test sample to move in the first direction, the first nozzle assembly first performs the first inkjet operation, thereby leaving the first ink mark on the test sample and identifying it as the first first ink line 210. When the preset time interval has passed, the second nozzle assembly performs the second inkjet operation, thereby leaving the second ink mark on the test sample and identifying it as the second ink line 220. When the preset time interval has passed again, the first nozzle assembly performs the third inkjet operation, thereby leaving the third ink mark on the test sample and identifying it as the second first ink line 210. In this way, the inkjet operation of the first nozzle assembly 170 and the second nozzle assembly 110 on the test sample is completed, and two first ink marks and one second ink mark are left on the test sample, a total of three ink marks, thereby obtaining the test sample 200 with ink marks, so as to compare the positional relationship between the first nozzle assembly 170 and the second nozzle assembly 110.

[0077] In addition, in step S101 of another embodiment, refer to Figure 10 , first sample 230 and second sample 240 are also provided on opposite sides of the test sample. The first sample 230 and the second sample 240 are also arranged on the conveyor belt and move along the first direction with the conveyor belt. In this embodiment, the ink marks on the test sample correspond to the ink marks ejected from the overlapping part after the first nozzle assembly 170 and the second nozzle assembly 110 are spliced, that is, the range covered by the test sample is the range where the first nozzle assembly 170 and the second nozzle assembly 110 can simultaneously eject ink. The ink marks on the first sample 230 correspond to the ink marks ejected from the non-overlapping part of the first nozzle assembly 170, that is, a part of the first ink line 210. Similarly, the ink marks on the second sample 240 correspond to the ink marks ejected from the non-overlapping part of the second nozzle assembly 110, that is, a part of the second ink line 220. Therefore, the first ink line and the second ink line on the test sample 200 with ink marks can be distinguished by identifying the ink marks on the first sample 230 and the second sample 240.

[0078] In step S102 of some embodiments, the test sample 200 with ink marks is identified and collected by a camera with a charge-coupled device image sensor and a vision sensor, thereby obtaining a first image. Using a camera with a charge-coupled device image sensor can collect the test sample 200 with ink marks more clearly.

[0079] Refer to Figure 5, in some embodiments, step S103 may include but is not limited to steps S201 to S202.

[0080] Step S201, grayscale and denoise the first image to obtain a third image.

[0081] Step S202, process the third image using the Canny edge detection algorithm to obtain a second image.

[0082] In step S201 of some embodiments, grayscale processing is adopted, that is, the red, green, and blue channels of each pixel point in the first image are compressed into a single gray channel, that is, the red, green, and blue pixel values of each pixel point in the first image are replaced with a grayscale value, and the grayscale value adopted in this application is 0.2989×R + 0.587×G + 0.114×B, where R, G, and B are the pixel values of the red, green, and blue channels in the first image respectively. Grayscaling the first image can make it more convenient for subsequent processing operations on the first image and improve efficiency. After grayscaling the first image, Gaussian filtering is then used to denoise the first image and retain edge information to a certain extent. Among them, Gaussian filtering performs a convolution operation on the first image using a Gaussian function, and its formula is as follows:

[0083]

[0084] Among them, G is a two-dimensional Gaussian function, δ is the standard deviation of the Gaussian distribution, which controls the degree of smoothing, and x and y represent the abscissa and ordinate of the pixel respectively. The convolution operation applies the Gaussian function to each pixel in the first image, and each pixel is replaced with the weighted average of the surrounding pixels adjacent to that pixel to achieve a smoothing effect, thereby realizing denoising. The weights are determined by the Gaussian function, but the Gaussian function weights each pixel inconsistently, with a larger weight for the pixel at the center of the first image and a gradually decreasing weight for the surrounding pixels. Replacing each pixel with the weighted average of the surrounding pixels adjacent to that pixel enables better retention of edge information, thereby obtaining a third image.

[0085] In step S202 of some embodiments, this step is actually an operation to enhance the third image, and its specific steps are as follows: The Canny edge detection algorithm is used to extract the edges in the third image to obtain accurate edge information. The specific steps are as follows: The Sobel operator is used to calculate the gradient of each pixel in the third image. The magnitude of the gradient represents the rate of change of brightness in the third image, that is, the intensity of the edge. The formula for the gradient is as follows:

[0086]

[0087] Among them, I is the brightness value of the image, Gx and G y are the gradients in the x and y directions, where x and y are the abscissa and ordinate of the pixel respectively.

[0088] Meanwhile, the intensity of the edge may be uneven in different directions. Therefore, the method of non-maximum suppression is adopted to remove the edges of non-local maximum values and retain the prominent edges. Finally, according to the preset high threshold and low threshold, the pixel points with edge intensity higher than the high threshold are regarded as edges, while those with edge intensity lower than the low threshold are regarded as non-edges. For the pixel points with edge intensity between the high threshold and the low threshold, if they are adjacent to the pixel points with edge intensity higher than the high threshold, then these pixel points are also regarded as edges, otherwise they are regarded as non-edges. Then, the pixels belonging to the edges are further connected, and finally the second image is obtained.

[0089] Steps S201 to S202 shown in the embodiments of the present application, by completing the preprocessing operation of the first image, make the obtained second image more convenient for subsequent recognition and operation.

[0090] In step S104 of some embodiments, there are two first ink lines 210, while there is only one second ink line 220. Among them, referring to Figure 10 , the second ink line 220 is printed between the two first ink lines 210 by the second nozzle assembly 110 to better judge the positional relationship between the first nozzle assembly 170 and the second nozzle assembly 110. Among them, since the two first ink lines 210 are both formed by inkjet of the first nozzle assembly 170, the two first ink lines 210 are in a parallel state, and the test sample moves along the first direction.

[0091] Referring to Figure 6 , in some embodiments, step S105 may include but is not limited to steps S301 to S303.

[0092] Step S301, convert the first ink line into a first straight line equation, determine the slope in the first straight line equation, and obtain the first slope.

[0093] Step S302, convert the second ink line into a second straight line equation, determine the slope in the second straight line equation, and obtain the second slope.

[0094] Step S303, compare the first slope and the second slope. When the first slope and the second slope are different, calculate the offset.

[0095] In step S301 of some embodiments, the Hough transform line detection method is used to convert two first ink lines 210 into polar coordinate form, and then according to the relationship between polar coordinates and rectangular coordinates, both two first ink lines 210 in polar coordinate form are converted into first linear equations with slope and intercept, and the slope therein is extracted to obtain a first slope. Since the two first ink lines 210 are parallel, the first slopes of the two first ink lines 210 are equal.

[0096] In step S302 of some embodiments, the Hough transform line detection method is used to convert the second ink line 220 into polar coordinate form, and then according to the relationship between polar coordinates and rectangular coordinates, the polar coordinate form of the second ink line 220 is converted into a second linear equation with slope and intercept, and the slope therein is obtained to get a second slope.

[0097] In step S303 of some embodiments, the obtained first slope and second slope are compared. If the slopes are equal, the next step is carried out. If the slopes are not equal, the calculation of the offset is carried out.

[0098] Steps S301 to S303 shown in the embodiments of the present application can reflect whether the corresponding first nozzle assembly 170 and second nozzle assembly 110 are in a parallel state by comparing the first slope and the second slope. If the slopes are not equal, the first nozzle assembly 170 and the second nozzle assembly 110 are in a non-parallel state. At this time, the splicing position of the nozzles can be regarded as an offset state, and then it turns to the step of calculating the offset.

[0099] Refer to Figure 6 In some embodiments, after step S303, it may further include but is not limited to steps S304 to S305.

[0100] Step S304, when the first slope and the second slope are the same, according to the first linear equation and the second linear equation, calculate the distance between the first ink line and the second ink line to obtain a first distance and a second distance.

[0101] Step S305, when the first distance and the second distance are not the same, then calculate the offset.

[0102] In step S304 of some embodiments, refer to Figure 10 The second ink line 220 is located between the two first ink lines 210. The first distance is the distance between the second ink line 220 and the upper first ink line 210, and the second distance is the distance between the second ink line 220 and the lower first ink line 210.

[0103] In step S305 of some embodiments, compare the numerical values of the first distance and the second distance. If the two are not equal, then turn to the step of calculating the offset.

[0104] In step S305 to step S306 shown in the embodiments of the present application, by calculating the distances between the second ink line 220 and the two first ink lines 210, it is convenient to determine whether the second ink line 220 is located exactly in the middle of the first ink lines 210. When the first distance and the second distance are equal, the first nozzle assembly 170 and the second nozzle assembly 110 are regarded as being perfectly spliced. When the first distance and the second distance are not equal, the offset amount thereof is calculated.

[0105] Referring to Figure 7 , in some embodiments, step S303 and step S305 may include but are not limited to steps S401 to S404.

[0106] Step S401, calculate the geometric center coordinates of the first ink line to obtain the first center coordinates.

[0107] Step S402, calculate the geometric center coordinates of the second ink line to obtain the second center coordinates.

[0108] Step S403, the first center coordinates include a first ordinate and a first abscissa, the second center coordinates include a second ordinate and a second abscissa, calculate the absolute value of the difference between the first ordinate and the second ordinate to obtain the first offset amount.

[0109] Step S404, calculate the absolute value of the difference between the first abscissa and the second abscissa to obtain the second offset amount.

[0110] In step S401 of some embodiments, since there are two first ink lines 210, in order to facilitate the calculation of the geometric center coordinates of the first ink line 210, the contours of the two first ink lines 210 are extracted as a thick line, and the second ink line 220 is located inside the thick line at this time. Then calculate the geometric center coordinates of the thick line to obtain the first center coordinates, wherein the first center coordinates include the abscissa and the ordinate of this point.

[0111] In step S402 of some embodiments, calculate the geometric center coordinates of the first ink line 210 according to the second straight line equation to obtain the second center coordinates, wherein the second center coordinates include the abscissa and the ordinate of this point.

[0112] In step S403 of some embodiments, respectively obtain the ordinates of the first center coordinates and the second center coordinates to obtain the first ordinate and the second ordinate, then subtract the first ordinate from the second ordinate and take the absolute value, thereby obtaining the first offset amount.

[0113] In step S404 of some embodiments, respectively obtain the abscissas of the first center coordinates and the second center coordinates to obtain the first abscissa and the second abscissa, then subtract the first abscissa from the second abscissa and take the absolute value, thereby obtaining the second offset amount.

[0114] Steps S401 to S404 shown in the embodiments of the present application extract the contours of two first ink lines 210 into a thick line, facilitating subsequent comparison of geometric center coordinates. By calculating the absolute value of the difference in the ordinates of the first center coordinate and the second center coordinate, the amount of adjustment required for the second nozzle assembly 110 in the ordinate direction can be determined. By calculating the absolute value of the difference in the abscissas of the first center coordinate and the second center coordinate, the amount of adjustment required for the second nozzle assembly 110 in the abscissa direction can be determined. In this way, the offset amount of the first ink line 210 can be judged in two directions, making the subsequent adjustment of the second nozzle assembly 110 more accurate.

[0115] Referring to Figure 8 , in some embodiments, step S106 may include but is not limited to steps S501 to S502.

[0116] Step S501, control the second driving member to lock.

[0117] Step S502, control the first driving member to drive the first push block so that the first convex portion drives the second nozzle assembly, prompting the second nozzle assembly to be adjusted along the ordinate direction according to the first offset amount.

[0118] In step S501 of some embodiments, after receiving the offset amount, first lock the second driving member 150 by controlling the adjustment module to ensure that the second push block 151 connected to the second driving member 150 is also in a locked state.

[0119] In step S502 of some embodiments, the adjustment module controls the first driving member 140 to drive the first push block 141 connected thereto to move in the vertical direction according to the first offset amount. When the first push block 141 moves downward in the vertical direction, the side wall of the first push block 141 presses against the first convex portion 121, and the first convex portion 121 is provided on the first connecting plate 120. The first connecting plate 120 is fixed to the first mounting plate 101, and the first mounting plate 101 is provided on the second nozzle assembly 110. Therefore, the movement of the first convex portion 121 will drive the second nozzle assembly 110 to move toward the side where the first convex portion 121 is provided, that is, move along the length direction of the first spring 162 and compress the first spring 162. At the same time, the movement of the second nozzle assembly 110 will also cause the third spring to deform; when the first push block 141 moves upward in the vertical direction, the side wall of the first push block 141 no longer presses against the first convex portion 121. At this time, under the reaction force of the third spring and the first spring 162, the second nozzle assembly 110 moves away from the side where the first convex portion 121 is provided along the length direction of the first spring 162.

[0120] Steps S501 to S502 shown in the embodiments of the present application lock the second driving member 150 and the second pushing block 151 to ensure that only the adjustable end is movable when the second nozzle assembly 110 is finely adjusted, thereby ensuring the accuracy of the adjustment. Among them, the first convex portion 121 has a structure with a gradually decreasing cross-sectional area from top to bottom. The design of driving the second nozzle assembly 110 to move by the first convex portion 121 through the first pushing block 141 enables the end of the second nozzle assembly 110 provided with the first convex portion 121 to perform a "tail-swinging" movement along the vertical coordinate, thereby realizing the fine adjustment of the second nozzle assembly 110 in the vertical coordinate. Among them, the distance that the first pushing block 141 moves in the vertical direction and the distance that the second nozzle assembly 110 moves in the vertical coordinate are in a linear relationship. Replacing different first pushing blocks 141 results in different linear relationships, which is convenient for adapting to more scenarios.

[0121] Referring to Figure 8 , in some embodiments, after step S502, it may further include but is not limited to steps S503 to S504.

[0122] Step S503, control the first driving member to lock.

[0123] Step S504, control the second driving member to drive the second pushing block to make the second convex portion and the third convex portion drive the nozzle assembly, so as to urge the second nozzle assembly to be adjusted along the horizontal coordinate direction according to the second offset.

[0124] In step S503 of some embodiments, after receiving the offset, first lock the first driving member 140 by controlling the adjustment module to ensure that the first pushing block 141 connected to the first driving member 140 is also in a locked state.

[0125] In step S504 of some embodiments, the adjustment module controls the second driving member 150 to drive the connected second pushing block 151 to move in the vertical direction according to the second offset. When the second pushing block 151 moves downward in the vertical direction, the side wall of the second pushing block 151 presses against the second convex portion 131 and the third convex portion 132 that are in contact with it. The second convex portion 131 and the third convex portion 132 are provided on the second connecting plate 130. The second connecting plate 130 is fixed to the second mounting plate 102, and the second mounting plate 102 is provided on the second nozzle assembly 110. Therefore, the movement of the second convex portion 131 and the third convex portion 132 will drive the second nozzle assembly 110 to move in the direction close to the first pushing block 141, that is, move along the length direction of the second spring 161 and compress the second spring 161. At the same time, the movement of the second nozzle assembly 110 will also cause the third spring to deform. When the second pushing block 151 moves upward in the vertical direction, the side wall of the second pushing block 151 no longer presses against the second convex portion 131 and the third convex portion 132. At this time, under the reaction force of the third spring and the second spring 161, the second nozzle assembly 110 moves in the direction away from the first pushing block 141 along the length direction of the second spring 161.

[0126] It should be noted that in some embodiments, after step S504 is completed, it will jump to implementation step S101 to achieve a cycle, so as to monitor the splicing position of the second nozzle assembly 110 in real time, ensure the accuracy of adjustment, and fully realize the automatic adjustment of the second nozzle assembly 110. Even if the second nozzle assembly 110 is manually offset after adjustment, accurate adjustment can be performed in the next cycle.

[0127] It should be noted that: The method of the embodiments of the present application is for the position adjustment of two nozzle assemblies. When a new nozzle assembly needs to be adjusted, the original second nozzle assembly 110 will be used as the new first nozzle assembly 170, and the newly introduced nozzle assembly will be used as the new second nozzle assembly 110. Then, the method of the embodiments of the present application is implemented to achieve the position adjustment when multiple nozzle assemblies are spliced.

[0128] Steps S503 to S504 shown in the embodiments of the present application lock the first driving member 140 and the first pushing block 141 to ensure that only the adjustable end of the second nozzle assembly 110 can move when fine-tuning is performed, thereby ensuring the accuracy of adjustment. Among them, the second pushing block 151 also has a structure with a cross-sectional area decreasing from top to bottom. The design of driving the nozzle assembly to move by the second convex portion 131 and the third convex portion 132 through the second pushing block 151 enables the second nozzle assembly 110 to move in the horizontal coordinate direction, that is, move away from or close to the first pushing block 141, thereby realizing the fine-tuning of the second nozzle assembly 110 in the horizontal coordinate. Among them, the distance that the second pushing block 151 moves in the vertical direction and the distance that the second nozzle assembly 110 moves in the horizontal coordinate have a linear relationship. By replacing different second pushing blocks 151, the linear relationship is also different, which is convenient for adapting to more scenarios.

[0129] Referring to Figure 9 , Figure 9 is a schematic structural diagram of a nozzle adjustment device according to an embodiment of the second aspect of the present application; the nozzle adjustment device of the embodiment of the present application is applied to Figure 4 the inkjet printing device shown in the schematic diagram. The nozzle adjustment device includes:

[0134] In the embodiment of the present application, the inkjet control module 1001 first performs an inkjet operation on a test sample sheet with the first printhead assembly 170 and the second printhead assembly 110 to be adjusted. After the ink marks on the test sample sheet are identified and collected by the image detection control module, preprocessing is performed to obtain a second image. The first ink line 210 and the second ink line 220 in the second image are obtained, where the first ink line 210 is formed by inkjetting of the first inkjet assembly, and the second ink line 220 is formed by inkjetting of the second inkjet assembly. The offset analysis module 1003 calculates the offset according to the first ink line 210 and the second ink line 220. Finally, when the offset is non-zero, the correction control module 1004 prompts the offset control adjustment module to adjust the second printhead assembly 110 according to the offset. In this way, there is no need for manual adjustment, realizing automatic fine adjustment of the splicing printheads, improving the efficiency and reducing the labor cost at the same time.
