Description

Technical Field

[0001] This invention relates to the field of industrial automation monitoring, specifically a method for monitoring the trajectory of rolling motion. Background Technology

[0002] In industrial production, rolling mills are key equipment for shaping glass, metal, and non-metal materials. The stability of their motion trajectory directly affects the processing accuracy and quality of the products. If the trajectory deviates during the rolling process, it may lead to problems such as out-of-tolerance product dimensions and surface defects, or even equipment failure, resulting in economic losses. Therefore, real-time and high-precision monitoring of the rolling motion trajectory is of great significance.

[0003] Traditional rolling trajectory monitoring methods mainly include two types: one is a monitoring method based on contact sensors (such as displacement sensors and pressure sensors), which obtains position information by installing sensors on the rolling equipment or object. However, this method has problems such as complex installation, sensor failure due to oil contamination and vibration, and it cannot directly locate the contact surface between the rolling mill and the object, resulting in low accuracy in trajectory deviation judgment. The other type is a monitoring method based on machine vision. In the early days, traditional image processing algorithms (such as threshold segmentation and edge detection) were used for target recognition. However, these algorithms have poor adaptability to changes in lighting and background interference, and it is difficult to accurately distinguish the rolling mill and object areas in complex industrial environments, resulting in large contact surface positioning errors and failing to meet the requirements of high-precision monitoring. In recent years, deep learning target recognition models (such as the YOLO series) have been applied in industrial inspection. However, current technologies only use the YOLO model for target positioning without combining clustering algorithms for accurate segmentation of the contact surface. This results in the inability to obtain the precise coordinates of the contact surface during trajectory analysis, leading to a lag in deviation judgment. Therefore, there is an urgent need for a method that can achieve accurate segmentation of the contact surface between the rolling mill and the object and real-time trajectory monitoring. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides a method for monitoring the rolling motion trajectory.

[0005] This invention is implemented by constructing a method for monitoring the trajectory of rolling motion. The device includes the following steps:

[0006] Step 1: Place the steel plate in the rolling mill and use the second adjustment component to drive the clamping and fixing between the rolling mill and the steel plate, ensuring that the placement position is aligned with the transmission path of the equipment to avoid displacement or shaking during the rolling process.

[0007] Step 2: After initial fixing, the distance between the steel plate and the sensor is positioned using the first adjustment component. Based on the thickness of the steel plate and the requirements of the rolling process, the distance is adjusted to the optimal monitoring distance to ensure the clarity and accuracy of the sensor image acquisition.

[0008] Step 3: Acquire image data during the rolling process using the data acquisition component at a preset frame rate, and input the image data into the first coordinate set of the rolling area and the second coordinate set of the object area output by the data acquisition component;

[0009] Step 4: Extract the edge pixels from the first coordinate set and the second coordinate set to form a pixel set; input the pixel set into the K-means clustering algorithm, set the number of clusters to 2 (corresponding to the rolling edge and the object edge respectively), and obtain the cluster centers of the two types of pixels through iterative calculation; determine the boundary of the two types of pixels based on the distance relationship between the cluster centers and the pixels, and this boundary is the contact surface between the rolling and the object;

[0010] Step 5: Record the coordinates of the contact surface at different times to generate the actual motion trajectory; retrieve the preset trajectory and calculate the coordinate deviation between the actual trajectory and the preset trajectory at the same time node; if the deviation values ​​at N consecutive time nodes all exceed the preset deviation threshold (N≥3), the rolling operation is determined to be abnormal, and the data acquisition component is triggered to issue a prompt.

[0011] Step Six: The data acquisition action is carried out synchronously with the rolling action of the rolling equipment to ensure the integrity and timeliness of the data acquisition, and to ensure that there is no data omission or time difference during the rolling process, thus providing a guarantee for the accurate monitoring of the rolling motion trajectory.

[0039] This invention provides an improved method for monitoring the trajectory of rolling motion, the working principle of which is as follows;

[0040] First, when using this equipment, place it in the work area, and then connect it to an external power source to provide the necessary electrical energy for its operation.

[0041] Secondly, when this equipment is needed, the steel plate can be placed on the conveyor belt 4 first. Then, the industrial computer 23 can control the conveyor belt 4 to start conveying the steel plate so that it contacts the upper pressure roller 21 and the lower pressure roller 22. Then, the rolling mill 1 can be controlled to start the lower pressure roller 22 to rotate, and the lower gear 31 fixed to it will rotate synchronously, driving the lower driven gear 33 to rotate. At the same time, the lower incomplete gear plate 32 will deflect at an angle with the rotation of the lower gear 31 and the lower driven gear 33, with the connection point at the lower end of the fixed frame 34 as the axis. Then, the upper driven gear 35 is driven to rotate. When the upper driven gear 35 rotates, it drives the upper gear 36 to rotate synchronously, which in turn drives the upper pressure roller 21 fixed to it to rotate synchronously. When the lower incomplete gear plate 32 deflects at an angle, it will drive the upper incomplete gear plate 37 to deflect synchronously around the connection point with the upper end of the fixed frame 34. Its angle deflection can further constrain the movement trajectory of the upper gear 36 and the upper driven gear 35, and finally realize that the distance between the upper pressure roller 21 and the lower pressure roller 22 is reduced synchronously to clamp the steel plate or expanded to loosen the steel plate.

[0042] Example 2:

[0043] Please see Figures 1-4 Compared to Embodiment 1, the rolling motion trajectory monitoring method of the present invention further includes: a height adjustment component 26 comprising an industrial camera mounting box 261, a protective window 262, a guide slide rod 263, a motor 264, and a threaded rod 265. The industrial camera mounting box 261 is fixedly connected to the left end of the rolling mill 1, the protective window 262 is fixedly connected to the right end of the industrial camera mounting box 261, the guide slide rod 263 is fixedly connected to the front end inside the industrial camera mounting box 261, the motor 264 is fixedly connected to the rear side of the upper end of the industrial camera mounting box 261, and the threaded rod 265 is rotatably connected to the rear end inside the industrial camera mounting box 261.

[0044] The height adjustment assembly 26 includes a movable frame 266, a threaded groove 267, and an industrial camera assembly 24. The left end of the movable frame 266 is slidably connected to the guide slide rod 263. The movable frame 266 is slidably connected inside the industrial camera mounting box 261. The threaded groove 267 is located at the right end of the movable frame 266. The upper end of the threaded rod 265 is fixedly connected to the lower end of the motor 264. The right end of the movable frame 266 is threadedly connected to the threaded rod 265 through the threaded groove 267.

[0045] In this embodiment:

[0046] First, when monitoring is required, the height adjustment component 26 can be controlled by the industrial computer 23 to initiate real-time image data acquisition and transmission to the industrial computer 23. The industrial computer 23 then uses the Huading visual recognition algorithm model to detect the rolling area and the sheet material area, and the industrial camera component 24 acquires at least 5000 images under different lighting conditions, angles, and rolling conditions. The Labellmg annotation tool is used to annotate the rolling equipment area, the object to be processed area, and the contact surface with rectangular boxes in VOC format. The annotated dataset is then divided into training, validation, and test sets in a 7:2:1 ratio. Finally, the industrial computer 23 performs grayscale processing on the images of the rolling area and the object area. The color image is converted to a grayscale image. The Canny edge detection algorithm is used, with a high threshold of 200 and a low threshold of 100, to extract edge pixels. Isolated noise points and connected regions with an area less than 5 pixels are removed to obtain a set of edge pixels. This set is then input into a K-means clustering algorithm, with two clusters: rolling edges and object edges. Two cluster centers are initialized, and the Euclidean distance from each pixel to the two centers is calculated. Pixels are assigned to the clusters with closer distances. The cluster centers are updated to the mean coordinates of the pixels in that cluster. This iteration is repeated until the cluster centers no longer change, with no more than 50 iterations. Based on the clustering results, the boundary between the two pixel classes is determined; this boundary is the contact surface, and the coordinate set of the contact surface is output.

[0047] Second, when trajectory analysis and anomaly judgment are required, the coordinates of the contact surface are recorded in chronological order, with one coordinate point recorded every 0.2 seconds, generating the actual motion trajectory curve. A preset trajectory, stored in the database according to processing requirements, is retrieved. The coordinate deviation d(t) between the actual trajectory and the preset trajectory at the same moment is calculated. Using the formula, the coordinates of the preset trajectory at time t are (x0(t), y0(t)), and the coordinates of the actual trajectory at time t are (x1(t), y1(t)). The deviation value is then calculated. The preset deviation threshold is set according to the processing accuracy requirements of the rolling equipment, and the value range is 0.1-0.5mm. The preset deviation threshold is set to 0.3mm. If the deviation value exceeds the threshold for 3 consecutive moments (0.6 seconds), the rolling operation is judged to be abnormal, and the audible and visual alarm is triggered. At the same time, the abnormal position and deviation value are displayed on the host computer. When the deviation value exceeds 0.2mm for 3 consecutive moments, the audible and visual alarm 25 is activated to trigger the audible and visual alarm.

[0048] Third, when the position of the industrial camera assembly 24 needs to be adjusted, the motor 264 can be started to drive the threaded rod 265 to rotate. When the threaded rod 265 rotates, the moving frame 266 can be moved up and down to the designated position. When the moving frame 266 moves up and down, the industrial camera assembly 24 can be moved up and down synchronously to the designated position. The distance between the industrial camera assembly 24 and the steel plate is precisely adjusted until the optimal acquisition distance is reached.

[0049] This invention provides an improved method for monitoring the rolling motion trajectory. By incorporating a height adjustment component 26 in the monitoring assembly 2, the position of which can be adjusted via a movable frame 266 and a threaded rod 265, the method comprehensively captures the motion trajectories of the upper pressure roller 21 and the lower pressure roller 22. Combined with the analysis function of the industrial computer 23 and the audible and visual alarm 25, it can promptly detect trajectory anomalies and issue warnings. The stabilization adjustment component 3, through the linkage of components such as the lower gear 31, the lower incomplete gear plate 32, and the upper driven gear 35, ensures stable operation of the upper and lower pressure rollers and improves rolling accuracy. The conveyor belt 4 and the output placement plate 5 can also assist in material transfer and finished product placement, optimizing the overall process. The entire system can achieve accurate monitoring of the rolling trajectory and stable operation control, reducing the occurrence of faults and effectively improving the quality and efficiency of rolling operations. Furthermore, the monitoring device requires no manual intervention throughout the process, automatically issues warnings in case of anomalies, and supports incremental model updates to maintain monitoring accuracy over the long term.
