Description

Technical Field

[0001] The present invention relates to the field of strip steel rolling, and in particular to a strip steel defect removal method and related equipment. Background Art

[0002] In the field of surface quality defect inspection of cold rolling recoiling units, surface defects of cold rolled strips need to be removed after inspection and confirmation by quality inspectors. Since there is a certain distance between the inspection station and the slitting shear, the defects follow the strip to a certain distance in front of the slitting shear before being removed to ensure that the defects are completely removed. In the process of the defects following the strip to the slitting shear, since the defect stop position needs to be manually judged, the defect stop positioning is often inaccurate. For example: if the defect stops too early, the defect is far away from the slitting shear, and too much of the normal part of the strip is removed, resulting in a loss of yield; if the defect stops too late, the defect stops after the slitting shear, and the slitting shear cannot complete the defect removal, resulting in quality omissions or secondary removal after adjustment, affecting production efficiency. Therefore, there is currently a lack of a more accurate removal method for defects in strips in production. Summary of the Invention

[0003] In view of the above problems, the present invention provides a strip defect removal method and related equipment, the main purpose of which is to solve the problem of the lack of a more accurate removal method for defects in strip steel in current production.

[0004] To solve at least one of the above technical problems, in a first aspect, the present invention provides a method for removing defects from a strip steel, the method comprising:

[0005] When the steel strip passes through the inspection area of ​​the inspection table, obtaining defect locations of the target steel strip;

[0006] determining a target distance based on an initial distance from an end point of the detection area to an exit shear, wherein the target distance is less than the initial distance;

[0007] When the defect location moves the target distance from the end point of the inspection area, the outlet shear is activated to perform a cutting action.

[0008] Optionally, the above method further includes:

[0009] In case the defect location moves out of the end point of the inspection area, visual tracking of the defect is initiated.

[0010] Optionally, the difference between the target and the initial distance is 200MM-300MM.

[0011] Optionally, the above method further includes:

[0012] Obtaining the real-time running speed of the steel strip;

[0013] The target distance compensation value is dynamically calculated according to the real-time running speed and the preset shearing reaction time.

[0014] Optionally, the above method further includes:

[0015] The roller speed is detected by an encoder to monitor the actual moving distance of the defect location in real time;

[0016] When the deviation between the actual moving distance and the target distance exceeds the threshold, the start time of the outlet shear is dynamically adjusted.

[0017] Optionally, the above method further includes:

[0018] When the cutting action of the outlet shear is completed, a process log including the defect location, defect size and cutting parameters is generated.

[0019] Optionally, the above method further includes:

[0020] When the cutting action of the exit shear is completed, the strip tension adjustment system is triggered to perform dynamic compensation.

[0021] In a second aspect, an embodiment of the present invention further provides a strip defect removal device, comprising:

[0022] an acquisition unit, configured to acquire the defect location of the target steel strip when the steel strip passes through the detection area of ​​the inspection table;

[0023] a determining unit, configured to determine a target distance based on an initial distance from an end point of the detection area to an exit shear, wherein the target distance is smaller than the initial distance;

[0024] A starting unit is used to start the outlet shear to perform a cutting action when the defect location moves the target distance from the end point of the detection area.

[0025] In order to achieve the above object, according to a third aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium includes a stored program, wherein when the program is executed by a processor, the steps of the above-mentioned strip defect removal method are implemented.

[0026] In order to achieve the above-mentioned purpose, according to the fourth aspect of the present invention, an electronic device is provided, comprising at least one processor and at least one memory connected to the processor; wherein the above-mentioned processor is used to call the program instructions in the above-mentioned memory to execute the steps of the above-mentioned strip defect removal method.

[0027] By leveraging the above-mentioned technical solution, the present invention provides a strip defect removal method and related equipment that address the current lack of a more accurate method for removing defects from strips in production. The present invention obtains the target strip defect location as the strip passes through the inspection area of ​​an inspection table; determines a target distance based on the initial distance from the endpoint of the inspection area to the exit shear, where the target distance is less than the initial distance; and activates the exit shear to perform a removal action when the defect location moves the target distance from the endpoint of the inspection area. In this solution, as the strip passes through the inspection area, the system scans the surface using a high-definition camera array, precisely marking the location coordinates of each defect. This information is then locked, effectively giving each defect a "digital ID." The system automatically calculates the original distance from the inspection endpoint to the shear (e.g., 20 meters), but does not directly use this value. Instead, it dynamically shortens the effective range (e.g., to 19.6 meters) based on factors such as the actual strip speed and equipment response delay. This effectively sets a "lead time" for the shearing action, offsetting errors introduced by equipment response time. When the strip with defects moves the corrected target distance, the system instantly triggers the shearing machine to operate.

[0028] Correspondingly, the strip defect removal device, equipment and computer-readable storage medium provided by the embodiments of the present invention also have the above-mentioned technical effects.

[0029] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are specifically listed below.

[0035] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] In order to solve the problem of lack of a more accurate removal method for defects in strip steel in current production, an embodiment of the present invention provides a strip defect removal method, such as Figure 1 As shown, the method includes:

[0037] S101, obtaining defect locations of a target steel strip when the steel strip passes through an inspection area of ​​an inspection table;

[0038] For example, the inspection table is the core area for strip surface quality inspection and is usually equipped with a high-precision optical inspection system (such as a multispectral imager or a linear array camera). As the strip continuously passes through this area, the system scans the strip surface at high speed to form a complete surface quality image.

[0039] During the detection process, accurate positioning is achieved through the following methods:

[0040] Coordinate mapping: Binds the detected defect location to the physical coordinate system of the strip's trajectory. For example, when the strip is running at 5 meters per second, the system records the absolute position of the defect from the strip head with 0.1 mm accuracy (e.g., the defect is located at 1234.56 meters along the strip's length).

[0041] Spatial marking: A three-dimensional spatial mark is established for each defect, which not only records the longitudinal position, but also marks the lateral offset (such as 35MM from the edge of the strip) and the defect depth information.

[0042] S102, determining a target distance based on an initial distance from the end point of the detection area to the exit shear, wherein the target distance is smaller than the initial distance;

[0043] For example, the initial distance refers to a fixed physical distance (e.g., 20 meters) between the end point of the detection area and the mechanical installation location of the outlet shear. This distance is a static parameter during production line design and reflects the spatial relationship of the equipment layout.

[0044] In actual production, the system will proactively shorten the initial distance (for example, set it to 19.7 meters) to compensate for the following two key factors: Equipment response delay: The exit shear requires time (e.g., 0.1 seconds) from receiving the instruction to completing the shearing action. Assuming the strip speed is 5M / S, the corresponding movement distance of the delay is 0.5M (500MM), and the shearing needs to be triggered in advance. Dynamic error prediction: The speed fluctuations that may exist during the strip operation (e.g., ±0.2M / S) are reserved for adjustment by shortening the distance.

[0045] S103 : When the defect location moves the target distance from the end point of the detection area, start the exit shear to perform a cutting action.

[0046] This technical solution establishes a dynamic tracking mechanism. Once the strip carrying the defect passes the endpoint of the inspection area, the system continuously tracks the defect's real-time location. For example, the detection system updates the defect coordinates 1000 times per second, accurately calculating its movement trajectory. The system uses an encoder to capture real-time strip travel distance data. When the cumulative movement reaches a preset target distance (e.g., 19.7 meters), the system immediately issues a shearing command. For example, at a strip speed of 8 ms / s, the system triggers shearing 2.46 seconds after the defect has moved 19.7 meters. Upon receiving the command, the hydraulic system of the exit shear completes the blade closing action within 50 milliseconds. During this time, the strip is still moving (e.g., an additional 0.4 meters at 8 ms / s), but a lead calculation ensures that the defect is precisely positioned for shearing when the blade closes. A displacement triggering mechanism strictly aligns the shearing action with the defect's spatial location. For example, for a 30 mm defect, the system can control the cut length to within a range of 50 ± 5 mm.

[0047] like Figure 2 As shown, when the strip is running, after the strip D with surface defects passes the starting point A of the inspection table, in the AC section of the inspection table (A is the starting point and C is the end point), the specific position of the defect D is confirmed through visual inspection. The detection system binds the absolute position coordinates of the defect D to the running speed of the strip. When the defect D moves with the strip to the defect positioning starting position B of the inspection table, the system automatically activates the defect tracking control module. After the defect D passes the end point C of the inspection table, the system continuously calculates the real-time distance between the defect and the exit shear E. When the defect moves to 200-300MM in front of the exit shear E, the strip brake is triggered. After the strip stops completely: the exit shear E performs shearing according to the preset number of shear knives. The shearing action covers the area where the defect D is located and the front and rear safety margins. The defective strip segment after shearing falls into the scrap hopper F located on the left side of the exit shear E under the action of gravity. The qualified strip continues to be transported to the left to the coiling process.

[0048] By leveraging the above-mentioned technical solution, the present invention provides a strip defect removal method and related equipment that address the current lack of a more accurate method for removing defects from strips in production. The present invention obtains the target strip defect location as the strip passes through the inspection area of ​​an inspection table; determines a target distance based on the initial distance from the endpoint of the inspection area to the exit shear, where the target distance is less than the initial distance; and activates the exit shear to perform a removal action when the defect location moves the target distance from the endpoint of the inspection area. In this solution, as the strip passes through the inspection area, the system scans the surface using a high-definition camera array, precisely marking the location coordinates of each defect. This information is then locked, effectively giving each defect a "digital ID." The system automatically calculates the original distance from the inspection endpoint to the shear (e.g., 20 meters), but does not directly use this value. Instead, it dynamically shortens the effective range (e.g., to 19.6 meters) based on factors such as the actual strip speed and equipment response delay. This effectively sets a "lead time" for the shearing action, offsetting errors introduced by equipment response time. When the strip with defects moves the corrected target distance, the system instantly triggers the shearing machine to operate.

[0049] In one embodiment, the method further includes:

[0050] In case the defect location moves out of the end point of the inspection area, visual tracking of the defect is initiated.

[0051] For example, when a defect on the strip surface completely moves beyond the end of the inspection zone (i.e., the end of the inspection equipment's monitoring range), the system activates an independent visual tracking mechanism. At this point, although the defect has already moved beyond the initial inspection zone, the system continues to capture dynamic images and calibrate the position of the moving defect using newly added industrial cameras or auxiliary positioning devices. This tracking is similar to creating a "real-time movement trajectory profile" for the defect, allowing precise monitoring of the defect's actual position as the strip moves, even after it leaves the primary inspection zone.

[0052] After the equipment in the main inspection area (such as a line array camera) completes initial positioning, a dedicated tracking camera located behind the inspection area takes over, forming a monitoring relay. The image acquisition frequency is automatically adjusted based on the strip's running speed. For example, at high speeds, the image capture rate is 200 frames per second, while at low speeds, it is reduced to 50 frames per second to conserve resources. This multi-angle camera combination not only tracks the longitudinal travel of defects but also monitors their displacement across the strip's width.

[0053] The above technical solution can fill the monitoring gap between the detection area and the shearing equipment and avoid positioning drift caused by the lack of monitoring in the intermediate section. For example, after a 1-meter-long detection area is completed, the millimeter-level tracking accuracy is still maintained for the subsequent 10-meter moving path. When the running speed of the strip fluctuates (such as a sudden change from 5M / S to 5.5M / S), the visual tracking system can perceive the speed change in real time and automatically adjust the position prediction algorithm. Experimental data shows that when the speed fluctuates by ±15%, the cutting position deviation can still be kept less than ±3MM.

[0054] In one embodiment, the difference between the target and the initial distance is 200MM-300MM.

[0055] For example, shortening the theoretical distance by 200-300 mm (e.g., an initial distance of 20 meters becomes a target distance of 19.7 meters) can offset positioning drift caused by equipment delay. For example, when the strip is running at 8 m / s, a 0.1 second delay corresponds to an 800 mm error. However, a 300 mm pre-compensation ensures that the defect is accurately stopped within ±50 mm of the shear position.

[0056] When a defect approaches the exit shear, positioning based on the initial distance may result in shearing lag (e.g., the defect has moved behind the shear). Target distance correction triggers the shearing action earlier, completely eliminating the risk of missed cuts and increasing the success rate of defect removal.

[0057] In one embodiment, the method further includes:

[0058] Obtaining the real-time running speed of the steel strip;

[0059] The target distance compensation value is dynamically calculated according to the real-time running speed and the preset shearing reaction time.

[0060] For example, by real-time monitoring of the strip moving speed and dynamically adjusting the shear trigger position, the accuracy defects of traditional fixed distance compensation can be effectively solved.

[0061] The system continuously collects the actual movement rate of the strip through speed sensors installed on the production line. For example, when it detects that the strip is moving at 8 meters per second, combined with the inherent delay time (e.g., 0.2 seconds) required for the exit shearing device to complete the shearing action from receiving the instruction, the system automatically calculates that the strip will continue to travel a distance of 1.6 meters during this period, and therefore shortens the original target distance by 1.6 meters as a compensation value. This dynamic compensation mechanism can accurately offset the displacement error caused by the equipment's response lag, and even if the production line speed is adjusted or speed fluctuations occur, the system can still update the compensation amount in real time.

[0062] This technology can control the position deviation of defect removal within ±5 mm, improving the accuracy by more than 3 times compared with the traditional fixed compensation method. At the same time, it reduces material loss caused by excessive removal by about 1.2%, avoiding secondary rework caused by insufficient compensation.

[0063] In one embodiment, the method further includes:

[0064] The roller speed is detected by an encoder to monitor the actual moving distance of the defect location in real time;

[0065] When the deviation between the actual moving distance and the target distance exceeds the threshold, the start time of the outlet shear is dynamically adjusted.

[0066] Exemplarily, an encoder is installed on the rotating shaft of the conveyor belt drive roller or tension roller. A rotary encoder is installed to rotate synchronously with the roller. The encoder converts the angular displacement of the roller (number of rotations) into a pulse signal output through photoelectric or magnetic principles. It is understandable that the present application measures the circumference of the drive roller (or the circumference converted from the diameter) in advance and enters it into the system as a basic parameter. According to the encoder resolution (for example, 1000 pulses per revolution), the strip movement distance corresponding to a single pulse is calculated. When the defect is identified by a surface detector (such as a camera or eddy current probe), the pulse count value of the encoder at this time is recorded as the starting point. Subsequently, the encoder pulse increment is continuously read, multiplied by the length corresponding to the unit pulse, and the actual movement distance of the defect location is accumulated. When the system detects that the deviation between the actual position of the defect and the theoretical target position exceeds the preset safety range, that is, the threshold (such as ±5 mm), the compensation algorithm is automatically triggered to recalculate the optimal start time of the outlet shear.

[0067] For example, when the actual movement distance of the strip is 8 mm longer than expected due to tension fluctuations, the system will trigger the shearing action 1 millisecond in advance based on the original shearing time to accurately offset the displacement deviation.

[0068] In one embodiment, the method further includes:

[0069] When the cutting action of the outlet shear is completed, a process log including the defect location, defect size and cutting parameters is generated.

[0070] For example, this application establishes a complete quality traceability system by automatically recording key process data. After each shearing is completed, the system automatically collects and stores the precise location coordinates of the defect (such as 235.76 meters from the head of the strip), specific size characteristics (such as a strip defect with a length of 15MM and a width of 3MM) and corresponding shearing parameters (including more than 20 data such as strip running speed of 8.5M / S, shear trigger advance of 280MM, blade pressure value, etc.), forming a process log with a timestamp.

[0071] With the help of the above technical solution, a full-process digital traceability system is built to achieve accurate quality backtracking. When customers report that there is a quality problem with a roll of strip steel, the root cause of the problem can be identified in a short time by retrieving 28 parameters recorded in the log, including the precise defect coordinates (such as the third defect processed at 12:05:30 in roll 235, located 568.92 meters from the head of the strip steel), the cutting length (35MM), the rolling speed at that time (9.2M / S), the tension value (185KN), etc.

[0072] In one embodiment, the method further includes:

[0073] When the cutting action of the exit shear is completed, the strip tension adjustment system is triggered to perform dynamic compensation.

[0074] For example, the technical solution of automatically triggering tension compensation after the exit shear completes defect removal mainly solves the problem of sudden tension change caused by material breakage at the moment of strip shearing. When the shearing action cuts the strip, the originally evenly distributed stress will fluctuate violently (for example, a case shows that the tension value at the moment of shearing drops sharply from 180KN to 70KN). At this time, the system captures the tension change curve through a real-time monitoring device and starts the hydraulic servo system to dynamically adjust the pressure distribution of each tension roller group. For example, after a production line cuts off a 2-meter-long defective section, the compensation system immediately increases the clamping force of the front and rear tension rollers by 15%, and at the same time reduces the speed of the coiler by 3%, so that the strip returns to a stable tension state within 0.5 seconds. The real-time response of the above dynamic compensation ensures production continuity and product consistency.

[0075] Furthermore, as a response to the above Figure 1 In order to realize the method shown in the figure, the embodiment of the present invention also provides a strip defect removal device for the above-mentioned Figure 1 This device embodiment corresponds to the aforementioned method embodiment.
