Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and more specifically, to a method, system, equipment, and medium for correcting deviations in packaging and printing. Background Technology

[0002] Existing algorithms for linear charge-coupled device (CCD) correction sensors only search for single edges within the field of view that meet the grayscale threshold conditions. The tracking results are easily affected by the scanning direction of the CCD camera. When there are other edges or broken edges near the target line on the material to be corrected, the tracking is prone to deviation, resulting in excessively high requirements for the material and ineffective correction of multi-line materials. Furthermore, if the initial calibration value is fixed, changes in material tension and vibration during actual production can cause changes in the brightness of the lines, thereby leading to dynamic tracking and correction deviations.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Existing packaging and printing methods for correcting product deviation by tracking target lines can lead to tracking errors when other edges or broken edges are present near the target lines. This results in excessively high material requirements and ineffective correction for multi-line materials. Furthermore, if the initial calibration values ​​are fixed, changes in material tension and vibration during actual production can alter the brightness of the lines, causing dynamic tracking and correction deviations. Therefore, this application provides a packaging and printing deviation correction method. This method acquires image feature data and real-time position feature data of the product on the conveying device. Based on the image feature data, it determines the product's correction reference parameters. Based on the correction reference parameters and position feature data, it obtains correction parameters. Based on the correction parameters, it generates correction instructions. It controls the correction device to execute the correction instructions to adjust the product's position on the conveying device to the target position, thereby improving correction accuracy. Simultaneously, without modifying the hardware, it retains the previous edge-tracking correction function, realizing the correction function of area scan cameras in the packaging and printing industry, reducing production costs and material scrap rates.

[0020] This application provides a packaging printing correction system, see below. Figure 1 As shown in the figure, the packaging printing correction system provided in this application includes a detection device 110, a correction device 120, and a control device 130. The control device 130 is signal-connected to the detection device 110 and the correction device 120, respectively. The detection device 110 is used to collect image feature data of the product on the conveying device and acquire position feature data of the product on the conveying device in real time. The correction device 120 is used to adjust the position of the product on the conveying device. The control device 130 is used to acquire image feature data of the product on the conveying device and acquire position feature data of the product on the conveying device in real time. Based on the image feature data, the correction reference parameters of the product are determined. Based on the correction reference parameters and the position feature data, correction parameters are obtained. Based on the correction parameters, correction instructions are generated. The correction device is controlled to execute the correction instructions to adjust the position of the product on the conveying device to the target position.

[0021] In this embodiment of the application, the detection device 110 is used to collect image feature data of the product on the conveying device and acquire position feature data of the product on the conveying device in real time. The image feature data can reflect the external feature information such as the appearance outline and surface line distribution of the product, while the position feature data can reflect the real-time placement of the product on the conveying device and the relative positional relationship between the product and the preset reference point of the conveying device. The detection device keeps synchronized during the collection of the two types of data to ensure that each set of image feature data can correspond to the position feature data at the same time, providing accurate and matching basic data for subsequent correction operations. The correction device 120 is used to adjust the position of the product on the conveying device. The correction device can act directly on the product or on a local area of ​​the conveying device. By applying force, it drives the product to move, thereby adjusting the position of the product. The control device 130 can receive image feature data and position feature data transmitted by the detection device, and can also send operation commands to the correction device. The control device is used to acquire image feature data of the product on the conveying device and acquire position feature data of the product on the conveying device in real time. Based on the image feature data, it determines the product's correction reference parameters. Specifically, it first converts the image feature data into grayscale image data, then selects the product's line feature data as the initial correction baseline parameters based on the grayscale image data and the line tracking reference. Then, through a traversal operation, it selects the line feature data located at the image feature data center location as the target correction reference parameters. The line tracking reference is the two lines of the line feature data. The grayscale change trends of the continuous edges are opposite; based on the correction reference parameters and position feature data, correction parameters are obtained. Specifically, the standard position corresponding to the correction reference parameters is compared and analyzed with the real-time position corresponding to the position feature data, and the deviation information between the two is calculated. This deviation information is the correction parameter; based on the correction parameters, correction instructions are generated. The correction instructions contain operational information such as the direction and amplitude of the correction device's movement; the correction device is controlled to execute the correction instructions to adjust the position of the product on the conveyor to the target position. After receiving the correction instructions, the correction device performs the corresponding adjustment actions according to the requirements of the instructions until the real-time position of the product is consistent with the preset target position.

[0022] Furthermore, in this application, the detection device can use a CCD line scan camera to acquire image feature data of the product and then output grayscale values ​​to the control device. The CCD line scan camera scans the grayscale values ​​of a total of 1,500 pixels within its field of view to obtain grayscale image data.

[0023] In this embodiment of the application, the control device is further configured to: convert the image feature data into grayscale values ​​to obtain grayscale image data; determine each initial correction baseline parameter in the product based on the grayscale image data; and, based on each initial correction baseline parameter, use a polling traversal operation to take the line feature data located at the image feature data center as the target correction reference parameter.

[0024] Furthermore, based on grayscale image data and line tracing reference, line feature data in the product is determined as the initial correction baseline parameter; the line tracing reference is determined as a complete line feature based on the opposite grayscale change trends of two consecutive edges of the line feature data, wherein the line feature data includes the line width value and the line height value; wherein the line height value is the grayscale difference between the two sides of the line.

[0025] Furthermore, based on grayscale image data and historical correction baseline parameters, the initial correction baseline parameters for each product are determined.

[0026] In practical implementation, the control device is also used to convert the image feature data into grayscale values ​​to obtain grayscale image data. Grayscale conversion is to convert the image feature data containing color information into image data that only reflects grayscale levels. Through this conversion, color interference can be weakened, and the line features on the product surface can be presented more clearly, laying the foundation for the accurate identification of subsequent line feature data. The control device determines the initial correction baseline parameters of the product based on grayscale image data. This can be achieved through two different methods: one is based on grayscale image data and a line-tracking reference, using line feature data as the initial correction baseline parameters. The line-tracking reference is determined by judging whether the grayscale change trends of two consecutive edges of the line feature data are opposite, thus defining a complete line feature. Only line features meeting this condition can be considered valid lines corresponding to the line-tracking reference. The line feature data includes the line width and line height values, where the line height specifically refers to the grayscale difference between the two sides of the line. By obtaining the line width and height values, more precise control can be achieved. One approach is to comprehensively characterize line features, improving the distinguishability and accuracy of initial correction baseline parameters and avoiding the misselection of invalid fine or interfering lines as initial correction baseline parameters. Another approach is to determine each initial correction baseline parameter in the product based on grayscale image data and historical correction baseline parameters. Historical correction baseline parameters are correction baseline parameters that have been verified as effective by the control device when performing correction operations on similar products in the past. Using historical correction baseline parameters as a reference can narrow the recognition range of line features and speed up the determination efficiency of initial correction baseline parameters. At the same time, the validity of historical data can be used to improve the reliability of initial correction baseline parameters, which is especially suitable for scenarios where similar products are continuously transmitted for correction. After obtaining the initial correction baseline parameters, the control device uses a polling traversal operation to select the line feature data located in the image feature data center as the target correction reference parameter. The polling traversal operation means that the control device sequentially detects the position of each initial correction baseline parameter and checks the specific position coordinates of each initial correction baseline parameter in the image feature data. This traversal method ensures that no initial correction baseline parameter is missed, guaranteeing the comprehensiveness of the selection. The line feature data located in the image feature data center is selected as the target correction reference parameter because lines in the center position are less affected by product edge damage, deformation, or local contamination, and have stronger stability. Using this as the correction reference can improve the accuracy of subsequent correction operations and reduce correction errors caused by reference offset.

[0027] The packaging and printing correction system provided in this application determines the target correction baseline parameters through the above operations. It not only provides multiple methods for determining the initial correction baseline parameters to suit different scenarios, enhancing the applicability of the solution, but also ensures the accuracy and stability of the target correction baseline parameters through grayscale conversion, accurate line tracking baseline judgment, and polling traversal filtering. This provides a reliable core reference for subsequent calculation of correction parameters and generation of correction instructions based on these parameters, thereby improving the accuracy and stability of the entire product correction process.

[0028] This application provides a packaging printing correction method, applicable to the control device in the aforementioned packaging printing correction system. (See attached document.) Figure 2 As shown, the general flow of the packaging printing correction method provided in this application embodiment is as follows: Step 210: Acquire image feature data of the products on the conveying device and acquire position feature data of the products on the conveying device in real time; Step 220: Determine the product's correction baseline parameters based on image feature data.

[0029] In this embodiment, grayscale image data is obtained by converting image feature data to grayscale values; based on the grayscale image data, each initial correction baseline parameter in the product is determined; based on each initial correction baseline parameter, a polling traversal operation is used to take the line feature data located at the image feature data center as the target correction reference parameter.

[0030] Furthermore, based on grayscale image data and line-tracing benchmarks, line feature data in the product is determined as the initial correction baseline; where the line-tracing benchmark is the grayscale change trend of two consecutive edges of the line feature data that are opposite.

[0031] Step 230: Obtain the correction parameters based on the correction reference parameters and location feature data.

[0032] Step 240: Generate correction instructions based on correction parameters.

[0033] Step 250: Control the correction device to execute the correction command to adjust the position of the product on the conveyor to the target position.

[0034] In specific implementation, firstly, image feature data of the product on the conveying device is acquired. Image feature data is external features that can reflect the outline lines and surface texture of the product. Secondly, position feature data of the product on the conveying device is acquired in real time. Position feature data is the real-time placement orientation of the product on the conveying device and its relative position information with respect to the preset reference position of the conveying device. Secondly, the acquired image feature data is converted to grayscale values ​​to obtain grayscale image data. Grayscale image data can clearly highlight the line features of the product, reduce the interference of color information on line recognition, and improve the convenience and accuracy of line feature recognition. Then, based on grayscale image data and the line-tracking benchmark, line feature data in the product is determined as the initial correction baseline parameters. The line-tracking benchmark is defined as the opposite grayscale change trends of two consecutive edges of the line feature data. Specifically, when identifying line features in grayscale image data, if two adjacent edge regions of a line exhibit opposite grayscale change trends (from dark to light and from light to dark), the line can be identified as line feature data conforming to the line-tracking benchmark. Line feature data selected using this standard accurately corresponds to the actual contour boundary of the product, avoiding the inclusion of irrelevant interference lines in the selection range of the initial correction baseline parameters. Based on each initial... The initial correction baseline parameters adopt a polling traversal operation, taking the line feature data located at the image feature data center as the target correction reference parameter. The polling traversal operation means that the position of all the selected initial correction baseline parameters is judged in turn, confirming the specific position of each initial correction baseline parameter in the image feature data one by one, and finally selecting the line feature data located at the center of the image. Selecting the line feature data at the center position as the correction reference parameter can make the reference benchmark of the correction operation more stable, reduce the impact of local damage or deformation of the product due to the selection of edge lines as the benchmark, and improve the reliability of the correction reference parameter. Next, the determined correction reference parameters are combined with the acquired position feature data for analysis. By comparing the standard position corresponding to the correction reference parameters with the real-time position of the product reflected by the position feature data, the correction parameters of the current position of the product and the standard position are calculated. Then, a correction command is generated based on the calculated correction parameters. The correction command contains relevant information such as the direction and amplitude of the correction device's movement. The correction command generated based on accurate correction parameters can directly guide the movement of the correction device and avoid errors in the correction operation due to command deviations. Finally, the generated correction command is sent to the correction device. After receiving the correction command, the correction device performs the corresponding adjustment action according to the command requirements, pushing the product on the conveyor to move its position until the product's position is adjusted to the preset target position.

[0035] The packaging printing correction method provided in this application uses collaborative analysis of image feature data and position feature data, combined with grayscale conversion and line tracking reference to select accurate correction reference parameters, and then generates corresponding correction instructions through deviation calculation. Finally, it drives the correction device to complete the product position adjustment, realizing the automated execution of the correction operation, reducing operational errors caused by manual intervention, improving the accuracy of product correction, ensuring that the product can be stably and accurately adjusted to the target position, greatly improving the correction efficiency during product transfer, and reducing product position deviation problems caused by manual operation or improper reference selection. It is applicable to product correction scenarios on various transfer devices and has strong versatility and practicality.
