[0048] The embodiment of the present invention provides a descaling method based on a straightening machine, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a descaling method based on a straightening machine according to the present invention.

[0049] In this embodiment, the straightening machine is applied, and the straightening machine is provided with a first pneumatic nozzle, a second pneumatic nozzle and an image acquisition device. The first angle of the first pneumatic nozzle is greater than the second angle of the second pneumatic nozzle. The first angle is the angle between the gas injection direction of the first pneumatic nozzle and the target plate, and the second angle is the angle between the gas injection direction of the second pneumatic nozzle and the target plate. The descaling method based on the straightening machine includes:

[0050] Step S1, receiving image data of the target plate passing through the straightening roller sent by the image acquisition device;

[0051] The first pneumatic nozzle and the second pneumatic nozzle are arranged behind the straightening roller of the straightening machine. The plate here generally refers to a metal plate, such as steel. During the straightening process, the plate will undergo plastic deformation, and the surface of the plate in contact with the air will form a layer of oxidizing substances, and since its material properties are different from those of the plate, the oxidized scales, i.e., oxide scales, will be obtained. The gas ejected by the first pneumatic nozzle and the second pneumatic nozzle is not limited, and can be air, nitrogen, etc. Optionally, the air flow velocity of the first pneumatic nozzle is greater than the air flow velocity of the second pneumatic nozzle to form a large flow and high impact air flow. The air nozzle shape of the first pneumatic nozzle can be a circular air nozzle, which can produce a concentrated air flow, and the air nozzle shape of the second pneumatic nozzle can be a flat air nozzle, which produces a wide and uniform air flow. And compared with chemical cleaning, removing oxidized scales by air flow can reduce the impact on the surface of the plate. The image acquisition device acquires image data of the surface of the target plate and uploads the image data.

[0052] Step S2, controlling the first pneumatic nozzle to spray gas toward a target position of the target plate according to the image data, where oxide flakes exist;

[0053] Specifically, the position of the oxide flakes in the target plate can be identified according to the image data, and then the target position is determined according to the position of the oxide flakes and the information of the oxide flakes. The target position here is the area on the oxide flakes that is easy to break, which can be the geometric center of the oxide flakes, or the upper edge area of ​​the oxide flakes, or the area with the smallest thickness on the oxide flakes. In this embodiment, the goal of the first pneumatic nozzle spraying gas to the target position is to break large pieces of oxide flakes into small pieces of oxide flakes, thereby improving the accuracy of subsequent cleaning of oxide flakes. The goal of the first pneumatic nozzle spraying gas here is not to take away the oxide flakes. It should be noted that since the diameter of the nozzle of the first pneumatic nozzle is small, that is, smaller than the diameter of the target position, in some embodiments, the first pneumatic nozzle can only spray gas to the center point of the target position. Of course, the first pneumatic nozzle can also be controlled to spray gas in a scanning manner to the target position, that is, the target position is sprayed with gas by continuously moving the first pneumatic nozzle.

[0054] Step S3, when it is detected that the oxide flakes at the target position are broken, the second pneumatic nozzle is controlled to spray gas toward the target position.

[0055] When the oxide flakes at the target position are detected to be broken, it means that the oxide flakes corresponding to the target position are identified to be broken due to external forces through the collected data. In some embodiments, it is generally possible to determine whether the oxide flakes are broken by image recognition. While controlling the first pneumatic nozzle to spray gas to the target position, gas can also be sprayed to a position adjacent to the target position. Optionally, the diameter of the nozzle of the second pneumatic nozzle can be larger than the corresponding diameter of the target position. Of course, the second pneumatic nozzle can be adjusted to be a flat nozzle so that the jetting area is larger.

[0056] In this embodiment, image data of the target plate passing through the straightening roller sent by the image acquisition device is received; the first pneumatic nozzle is controlled to spray gas toward the target position of the target plate according to the image data, so that the oxide flakes at the target position can be broken, avoiding the problem that large pieces of oxide flakes cannot be blown away, and when the oxide flakes at the target position are identified to be broken, the second pneumatic nozzle is controlled to spray gas toward the target position, thereby achieving accurate and efficient removal of the oxide flakes and avoiding affecting the surface quality of the plate.

[0057] Further, based on the first embodiment, a second embodiment of the descaling method based on a straightening machine of the present invention is proposed. In this embodiment, referring to Figure 3 The step of controlling the first pneumatic nozzle to spray gas toward the target position of the target plate according to the image data comprises:

[0058] Step S21, determining scale state data of the oxidized scale according to the image data;

[0059] Specifically, the state data of the oxidized scales in the target image data may be determined by one of the following methods: color difference, brightness difference, edge information extraction, and feature matching. The state data may include the pixel position of the pixel occupied by the oxidized scales, or the number of scales, the shape of scales, the scale area of ​​each oxidized scale, etc. Of course, in some embodiments, the thickness of the scales corresponding to different positions on the scales may also be judged or predicted by the color of the oxidized scales.

[0060] Step S22, determining the target position according to the scale state data;

[0061] The position of the oxidized scale that is prone to breakage can be determined as the target position based on the scale status data, or the center point of the oxidized scale can be determined as the target position. Of course, in some other embodiments, more than one target position can be set due to the large area of ​​a single oxidized scale.

[0062] Step S23, controlling the first pneumatic nozzle to move and spray gas according to the target position.

[0063] In this embodiment, specifically, the first angle of the first pneumatic nozzle is 90 degrees, the first pneumatic nozzle is arranged on a base, and the base is moved by two sets of slide rails whose gas jet directions of the first pneumatic nozzle are perpendicular to each other, and the sliding directions of the two sets of slide rails are perpendicular to each other. Thus, the movement of the first pneumatic nozzle can be controlled by controlling the motor to move the base, thereby improving the accuracy of moving the first pneumatic nozzle.

[0064] In this embodiment, the flake status data of the oxide flake is determined by the image data, and the target position is determined based on the flake status data, so that the position where the jet needs to be injected can be identified, and the first pneumatic nozzle is controlled to move and inject gas according to the target position, thereby improving the accuracy of moving the first pneumatic nozzle.

[0065] Further, based on the second embodiment, a third embodiment of the descaling method based on a straightening machine of the present invention is proposed. In this embodiment, referring to Figure 4 The step of determining the scale state data of the oxidized scale according to the image data further includes:

[0066] Step S211, extracting the position information of the oxidized scales in the image data by using an image recognition algorithm;

[0067] In this embodiment, the position information of the oxide flakes in the image data can be extracted by color recognition; the position information here is a set of two-dimensional coordinate points.

[0068] Step S212, determining the number of the oxidized flakes and the shape and area of ​​each oxidized flake according to the image segmentation algorithm and the position information;

[0069] Specifically, each pixel is classified into an oxidized scale pixel and a non-oxidized scale pixel, and a neighborhood range is defined. When there are pixels of the same type in the neighborhood, generally the same oxidized scale pixels, it is determined that the two oxidized scale pixels belong to the same oxidized scale, and each pixel in the image is traversed. The number of oxidized scales is determined, the corresponding scale shape of the oxidized scales is determined, and the scale area of ​​the oxidized scales is counted.

[0070] Step S213: taking the number of scales, the shape of scales and the area of ​​scales as the scale status data.

[0071] In other embodiments, the position information of the oxidized flakes in the image data may be extracted by an edge algorithm, and the number of flakes and the shape and area of ​​each oxidized flake may be determined.

[0072] In this embodiment, the position information of the oxidized scales in the image data is extracted by an image recognition algorithm, and the number of oxidized scales and the scale shape and scale area of ​​each oxidized scale are determined based on an image segmentation algorithm and the position information, thereby improving the accuracy of the obtained scale status data.

[0073] Furthermore, the image acquisition device is an infrared imaging device, and the step of extracting the position information of the oxide scales in the image data by using an image recognition algorithm comprises:

[0074] Comparing the pixel value of each image pixel in the image data with a preset pixel value interval;

[0075] When the pixel value is within the preset pixel value interval, determining that the image pixel corresponding to the pixel value is a scale pixel point of the oxidized scale;

[0076] The position coordinates of all the scale pixel points are extracted as the position information.

[0077] The infrared imaging device here refers to a thermal imaging camera, that is, an infrared camera, which can detect infrared radiation emitted by an object. Specifically, each pixel in the image of the infrared imaging device represents the light intensity at the corresponding position. The light intensity of infrared rays has a corresponding relationship with the temperature. Since the oxidized scales usually have a lower thermal conductivity than steel, the temperature difference between the oxidized scales and the target plate will be reflected in the collected image data. In this embodiment, the pixel value of each image pixel in the image data can be compared with a preset pixel value interval; when the pixel value is within the preset pixel value interval, the image pixel corresponding to the pixel value is determined to be a scale pixel point of the oxidized scale. In other embodiments, the scale temperature of the oxidized scale and the plate temperature of the plate after passing through the straightening machine are recorded, and the pixel value of each image pixel in the image data is converted into temperature data. Based on the temperature data, the comparison is performed with the scale temperature and the plate temperature to obtain a comparison result, and the position information is determined according to the comparison result.

[0078] In this embodiment, the pixel value of each image pixel in the image data is compared with a preset pixel value range; when the pixel value is within the preset pixel value range, the image pixel corresponding to the pixel value is determined to be a scale pixel point of an oxidized scale, and the position coordinates of all the scale pixel points are extracted as the position information, which is based on the object characteristics of the two areas to be distinguished, namely, the temperature difference. Therefore, the accuracy of the position information can be improved.

[0079] Further, based on the second embodiment or the third embodiment, a fourth embodiment of the descaling method based on a straightening machine of the present invention is proposed. In this embodiment, referring to Figure 5 The scale status data includes: the number of scales, the shape of scales and the area of ​​scales. The step of determining the target position according to the scale status data includes:

[0080] Step S221, determining an area threshold according to the number of scales;

[0081] Specifically, the area threshold is positively correlated with the number of scales, for example, when the number of scales is 1, the area threshold is 20 square centimeters, and when the number of scales is 10, the area threshold is 100 square centimeters. Therefore, when the number of scales on the target plate is less, the smaller the oxidized scales need to be broken. Of course, in some embodiments, optionally, before the step of receiving the image data of the target plate passing through the straightening roller sent by the image acquisition device, it also includes controlling the second pneumatic nozzle to spray gas to the target plate, so that before step S1, the oxidized scales that are easy to clean are cleaned, and when executing steps S221 and S222, the area threshold is set to zero, so as to determine that all oxidized scales are the target oxidized scales, and execute step S223.

[0082] Step S222, when the scale area of ​​the oxidized scale is greater than or equal to an area threshold, determining the corresponding oxidized scale as a target oxidized scale;

[0083] When the scale area of ​​the oxidized scale is smaller than an area threshold, it is determined that the corresponding oxidized scale does not need to be sprayed with gas by the first pneumatic nozzle.

[0084] Step S223, determining the target position according to the scale shape of the target oxidation scale, so as to obtain at least one target position.

[0085] Specifically, in this embodiment, when the scale shape of the target oxide scale is a convex polygon, the position of the geometric center of the convex polygon is determined as the target position. When the scale shape of the target oxide scale is a shape other than a convex polygon, an image opening operation is performed on the region of the target oxide scale in the image data, that is, a process of first corroding and then expanding. The image opening operation disconnects the narrow area, so that the target oxide scale is divided into two sub-target oxide scales at the disconnected area, and the position of the narrow area is used as the target position. It should be noted that the first pneumatic nozzle sprays gas to the target position of the target plate. The essence is to make the oxide scale subject to uneven external force. When the force acts on the edge or narrow area of ​​the object, the stress in these areas will be higher than that in other areas, so that the oxide scale is broken. Compared with the target position at the geometric center of the convex polygon, the position of the narrow area is more likely to be broken. The image opening operation in this embodiment is to find the narrow area of ​​the target oxide scale, and the role played is not to divide the area in the image. In some embodiments, the narrow part can also be determined by observation. Of course, in some embodiments, a plurality of different target positions may be set according to the characteristics of the scale shape of the target oxidation scale.

[0086] In this embodiment, by determining the area threshold according to the number of scales, and when the scale area of ​​the oxidized scale is greater than or equal to the preset area, the corresponding oxidized scale is determined to be the target oxidized scale, thereby screening the oxidized scales that need to be broken, so that the target position can be accurately selected, avoiding too many target positions, and thus improving the efficiency of phosphorus removal.

[0087] Further, based on any of the above embodiments, a fifth embodiment of the descaling method based on a straightening machine of the present invention is proposed. In this embodiment, after the step of controlling the first pneumatic nozzle to spray gas toward the target position of the target plate according to the image data, the method further includes:

[0088] receiving the scale image data sent by the image acquisition device;

[0089] Determining the crushing information of the target oxidized flakes corresponding to the target position according to the flake image data;

[0090] When the crushing information indicates that the target oxide flakes are not crushed, or when the crushing information indicates that the crushing result of the target oxide flakes does not meet the standard, the target position is adjusted, and the step of controlling the first pneumatic nozzle to spray gas toward the target position of the target plate according to the image data is returned to be executed.

[0091] The scale image data here is image data after the first pneumatic nozzle sprays gas toward the target position of the target plate.

[0092] Specifically, the target oxide flake crushing result here does not meet the standard means that the area of ​​the crushed oxide flakes obtained after crushing is greater than the area threshold. In this embodiment, in addition to adjusting the target position, the control parameters of the first pneumatic nozzle can also be adjusted. In addition, optionally, the first angle is 90 degrees and the second angle is 25 degrees. When the first angle is 90 degrees, the pressure generated by the gas ejected by the first pneumatic nozzle can be maximized.

[0093] In this embodiment, by receiving the flake image data sent by the image acquisition device, the crushing information of the target oxidized flake corresponding to the target position is determined according to the flake image data, and when the crushing information shows that the target oxidized flake is not crushed, or when the crushing information shows that the crushing result of the target oxidized flake does not meet the standard, the target position can be adjusted to ensure that the oxidized flake can be crushed, thereby improving the descaling effect.

[0094] In addition, an embodiment of the present invention further proposes a descaling system based on a straightening machine, which is applied to the straightening machine. The straightening machine is provided with a first pneumatic nozzle, a second pneumatic nozzle and an image acquisition device. The first angle of the first pneumatic nozzle is greater than the second angle of the second pneumatic nozzle. The first angle is the angle between the gas injection direction of the first pneumatic nozzle and the target plate, and the second angle is the angle between the gas injection direction of the second pneumatic nozzle and the target plate. The descaling system based on the straightening machine includes:

[0095] A receiving module, used for receiving the image data of the target plate passing through the straightening roller sent by the image acquisition device;

[0096] a processing module, configured to control the first pneumatic nozzle to spray gas toward a target position of the target plate according to the image data, where oxide flakes exist;

[0097] The cleaning module is used to control the second pneumatic nozzle to spray gas toward the target position when the oxide scale at the target position is detected to be broken.

[0098] In addition, an embodiment of the present invention also proposes a straightening machine, which includes: a memory, a processor, and a straightening machine-based descaling program stored in the memory and executable on the processor, wherein the straightening machine-based descaling program is configured to implement the steps of any of the straightening machine-based descaling methods described above.

[0099] In addition, an embodiment of the present invention further proposes a storage medium, on which a descaling program based on a straightener is stored. When the descaling program based on a straightener is executed by a processor, the steps of any of the above-mentioned descaling methods based on a straightener are implemented.
