[0066] Embodiment 1

[0067] In embodiment 1, the present application exemplarily shows a multifunctional strip steel detection platform, please refer to Figures 2-4 The multifunctional strip steel detection platform at least includes a lifting mechanism 1, a strip steel conveying mechanism 6, a felt laying mechanism 2, a polishing mechanism 3, a data acquisition device 4 and a data processing device 5, and each part will be specifically described as follows:

[0068] The lifting mechanism 1 is used to support the to-be-detected strip steel 61, and specifically includes a water platform surface 11 and a first driving assembly 12 for driving the water platform surface 11 to lift, and the first driving assembly 12 can include common lifting devices such as lifting cylinders, hydraulic cylinders or motors, etc.

[0069] The strip steel conveying mechanism 6 is used to convey the to-be-detected strip steel 61 to above the water platform surface 11, and includes but is not limited to common plate conveying devices such as transmission rollers, etc. in the field.

[0070] The felt laying mechanism 2 comprises a reel 21 and a winch 22 arranged on both sides of the water platform 11 respectively, and a felt 23 located above the water platform 11, one end of the felt 23 is connected to the winch 22 and is tensioned by the winch 22, and the other end is connected to the reel 21 and rotates with the reel 21, by rotating the reel 21, the felt 23 is laid on the water platform 11 or wound on the reel 21.

[0071] It can be understood that in the present embodiment, the reel 21 refers to a middle shaft structure that can rotate, and its specific structural form can be but is not limited to a solid shaft rod, a hollow shaft barrel, etc., and can be driven manually or by a driving device, so as to rotate and drive the end of the felt 23 connected thereto to rotate, and since the other end of the felt 23 is tensioned by the winch 22, the part of the felt 23 not wrapped around the shaft is taut above the water platform 11.

[0072] The polishing mechanism 3 comprises a polishing end 31 arranged above the water platform 11 and a second driving assembly for driving the polishing end 31 to ascend and horizontally move, and in some embodiments, the second driving assembly can comprise a first horizontal moving piece for driving the polishing end 31 to move in parallel to the conveying direction of the steel strip 61 to be inspected, and a second horizontal moving piece for driving the polishing end 31 to move perpendicular to the conveying direction of the steel strip 61 to be inspected, and the first horizontal moving piece and the second horizontal moving piece cooperate to move the polishing end 31 in different trajectories in the horizontal plane.

[0073] The data acquisition device 4 comprises but is not limited to an existing image acquisition device, an optical acquisition device or an acoustic acquisition device, etc., for acquiring data of the steel strip 61 to be inspected on the water platform 11, for example, in the present embodiment, the data acquisition device 4 here can comprise a camera for acquiring the polishing trace image of the polished steel strip 61 to be inspected, and can comprise a laser transceiver, an ultrasonic transceiver, etc. arranged based on the defect detection requirements of the unevenness of the surface of the steel strip 61 to be inspected;

[0074] The data processing device 5 is electrically connected with the data acquisition device 4, and is used for analyzing and processing the data collected by the data acquisition device 4, and it can be understood that the data processing device 5 at least has the recognition or analysis ability for the type of data collected by the data acquisition device 4, and its specific form comprises but is not limited to a computer or a computer group, an electronic device with data analysis or recognition function, a server or a cloud computer, etc.

[0075] It is worth noting that when polishing the steel strip 61 to be inspected, felt 23 needs to be laid under it to provide friction and ensure that the polishing track is clear and accurate, and when performing tolerance detection such as unevenness detection, the support surface below needs to be horizontal and smooth to reduce detection errors, so it can be seen that the water platform 11 supporting the steel strip 61 to be inspected also has different requirements in different detection requirements

[0076] In the above embodiment, the reel 21 and the winch 22 can lay or roll up the felt 23 on the water platform 11, so as to meet the support requirements of various detections such as polishing and unevenness detection. Meanwhile, the multifunctional strip steel detection platform is also integrated with the data acquisition device 4 and the data processing device 5, so as to collect detection data of different detection processes in the same station, analyze the collected data synchronously and in real time, save the conveying time between different detection links of the to-be-detected strip steel 61, facilitate synchronous analysis of multiple detection results of the to-be-detected strip steel 61, and avoid position deviation in the conveying process. It can be seen that, by integrating the mechanisms for functions such as felt 23 laying, polishing, data acquisition, and data processing in the same detection platform, the strip steel can be subjected to multiple types of detection operations in the same station, which effectively improves the detection form of the multiple-station operation in the prior art, greatly reduces the space occupation, and reduces the labor cost of strip steel detection. Meanwhile, multiple detections are completed in the same station, and the product defects are analyzed in real time by the data processing device 5, which replaces manual judgment, effectively reduces the risk of missed detection and missed judgment, and reduces the loss of waste or defective products.

[0077] It can be understood that the winch 22 and the reel 21 are arranged on the two sides of the water platform 11, and the purpose is to enable the felt 23 to cross the water platform 11, and the direction of the felt 23 crossing the water platform 11 is not limited. Therefore, in some embodiments, the reel 21 and the winch 22 can be arranged on the two sides of the water platform 11 perpendicularly to the conveying direction of the to-be-detected strip steel 61. The length direction of the to-be-detected strip steel 61 is the conveying direction, and the reel 21 and the winch 22 are arranged on the two sides of the water platform 11 perpendicularly to the conveying direction of the to-be-detected strip steel 61. That is, when the felt 23 is laid on the water platform 11, the felt 23 crosses the to-be-detected strip steel 61 in the width direction, so as to avoid that the size of the winch 22, the reel 21, or the felt 23 is too large, and the laying or rolling action of the felt 23 affects the conveying of the to-be-detected strip steel 61. In other embodiments, the actual structure, size, and arrangement position of the winch 22, the reel 21, or the felt 23 do not affect the conveying of the to-be-detected strip steel 61, and therefore the winch 22 and the reel 21 can be arranged on the two sides of the water platform 11 along the conveying direction of the to-be-detected strip steel 61, so as to reduce the overall space occupation. For example:

[0078] In the present embodiment, please refer to Figure 3 , Figure 4 The winch 22 includes two wires 221 arranged parallel to the conveying direction of the to-be-detected strip steel 61. The wires 221 are connected with the felt 23. For example, a wire buckle is arranged on the edge of the felt 23, the distance between the two wires 221 is greater than the width of the to-be-detected strip steel 61, and the vertical projection of the to-be-detected strip steel 61 during conveying is located between the two wires 221, so that the laying or rolling of the felt 23 does not affect the conveying of the to-be-detected strip steel 61.

[0079] In the present embodiment, please refer to Figure 3 , Figure 4 , the felt laying mechanism 2 further comprises a third driving assembly 24 for driving the reel 21 and the winch 22 to lift, it can be understood that the third driving assembly 24 includes but is not limited to common lifting devices such as air cylinders, hydraulic cylinders, etc., in some embodiments, in the application scenario such as detecting the to-be-detected steel strip 61, when the felt 23 is attached to the water platform surface 11, the third driving assembly 24 drives the reel 21 and the winch 22 to lift synchronously with the water platform surface 11, so that the force of the water platform surface 11 on the felt 23 is constant, so as to control or adjust the tension of the felt 23 only through the winch 22 and the reel 21.

[0080] In the present embodiment, please refer to Figure 3 , Figure 4 , the multifunctional steel strip detection platform further comprises a felt 23 cleaning mechanism, the felt 23 cleaning mechanism comprises a brush roller 71 arranged above the laying area of the felt 23, a fourth driving assembly for driving the brush roller 71 to rotate and lift, and a dust suction device, specifically, the fourth driving assembly comprises a motor connected with the shaft of the brush roller 71 for driving the brush roller 71 to rotate, and common lifting devices such as air cylinders, hydraulic cylinders, etc. connected with the brush roller 71 for driving the brush roller 71 to lift to attach to the felt 23, the brush roller 71 rotates to clean the metal dust on the felt 23, and the dust suction device can be various existing devices with negative pressure dust suction function, such as a suction head 72 connected with a negative pressure air pipe for sucking away the dust attached or raised by the brush roller 71, in the present embodiment, a dust cover 73 is further arranged above the brush roller 71, and the suction head 72 of the dust suction device can be arranged on the dust cover 73, the above-mentioned embodiments facilitate cleaning and maintenance of the felt 23, and prevent dust accumulation and dust raising.

[0081] In the present embodiment, the second driving assembly comprises a first horizontal moving piece for driving the polishing end head 31 to move parallel to the conveying direction of the to-be-detected steel strip 61, and a second horizontal moving piece for driving the polishing end head 31 to move perpendicular to the conveying direction of the to-be-detected steel strip 61, the first horizontal moving piece and the second horizontal moving piece cooperate to make the polishing end head 31 move in different trajectories in the horizontal plane, and the second driving assembly further comprises a first air cylinder 311 for driving the polishing end head 31 to lift, the upper end of the first air cylinder 311 is connected with the second horizontal moving piece, and the lower end is connected with a part for polishing the to-be-detected steel strip 61, such as an oil stone.

[0082] Further, in the embodiment, two first horizontal moving members are provided, and the two first horizontal moving members are respectively located on both sides of the conveying path of the to-be-inspected strip steel 61. The second driving assembly further comprises a telescopic member 322 connected between the two first horizontal moving members. The telescopic member 322 is hinged to the first horizontal moving members at both ends. The second horizontal moving member is connected to the telescopic member 322. Each first horizontal moving member independently drives one end of the telescopic member 322 to move. The specific principle comprises that the two first horizontal moving members move at different speeds along parallel tracks, so that the telescopic member 322 connected between the two first horizontal moving members is telescoped and an angle is generated in the horizontal plane. Since the second horizontal moving member is connected to the telescopic member 322, the angle is also synchronously superimposed on the movement path of the second horizontal moving member.

[0083] It can be understood that the first horizontal moving member and the second horizontal moving member comprise, but are not limited to, a device capable of generating reciprocating movement in a fixed direction, such as a motor, a pneumatic cylinder, a hydraulic cylinder, and a partial component of such a device or a component driven by the device. For example, in the exemplary embodiment shown in the embodiment, the first horizontal moving member is a guide wheel 321 driven by a motor to move along a fixed track 3211. The telescopic member 322 is a telescopic rod hinged between the two groups of first horizontal moving members. Specifically, the telescopic rod is a sleeve piston rod structure, and the telescoping is achieved by the movement of the piston rod in the sleeve. The guide wheel 321 is connected with a mounting rack 3212 for mounting connection. The piston rod ends at both ends of the telescopic rod are hinged to the mounting rack 3212. The second horizontal moving member comprises a second pneumatic cylinder 323 connected with a support, a plate member or a rod member extending from the telescopic rod. The polishing end 31 is connected with a pneumatic cylinder piston in the second pneumatic cylinder 323 and moves with the pneumatic cylinder piston. The adjustment of the gas pressure on both sides of the pneumatic cylinder piston in the second pneumatic cylinder 323 can drive the pneumatic cylinder piston to move in the second pneumatic cylinder 323.

[0084] As described above, in the multifunctional strip steel inspection platform shown in the embodiment, the mechanisms for functions such as felt laying, polishing, data acquisition and data processing are integrated into the same inspection platform, so that various types of inspection operations can be performed on the strip steel at the same station. The detection form of the multi-station operation in the prior art is effectively improved, the space occupation is greatly reduced, the labor cost of strip steel inspection is reduced, meanwhile, the multi-type detection is completed at the same station, and the product defects are analyzed in real time by the data processing equipment 5, replacing manual judgment, effectively reducing the risk of missed detection and missed judgment, and reducing the loss of waste or defective products.

[0090] S540, the to-be-inspected strip is subjected to data acquisition, and the inspection data is obtained and transmitted to the data processing device for analysis and processing.

[0091] For step 510, it is worth noting that, based on the structure of the multifunctional strip inspection platform shown in the foregoing embodiments, the conveying of the strip and the adjustment of the state of the felt are not affected by each other, and thus they can be implemented separately or synchronously.

[0092] For step S530, based on the multifunctional strip inspection platform shown in the foregoing embodiments, the inspection operation can include but is not limited to polishing operation by using the polishing mechanism, direct data acquisition by using the data acquisition device to perform the tolerance inspection operation, etc.

[0093] Specifically, in the present embodiment, the implementation of the above steps S510-S540 is further shown for different inspection requirements, please refer to Figure 6 , the inspection requirements include a first inspection requirement, and for the first inspection requirement, the strip inspection method steps S510-S540 are implemented by the following steps:

[0094] S610, based on the first inspection requirement, the felt is laid flat on the water platform surface;

[0098] S650, the data acquisition device acquires the polishing trace and transmits it to the data processing device for analysis and processing.

[0099] In the present embodiment, another implementation of the above steps S510-S540 is further shown, please refer to Figure 7 , the inspection requirements include a second inspection requirement, and for the second inspection requirement, the strip inspection method steps S510-S540 are implemented by the following steps:

[0104] It can be understood that in the above embodiment, the first detection requirement is the polishing detection requirement, the second detection requirement is the tolerance detection requirement including unevenness, and the first detection requirement and the second detection requirement refer to different detection types of operation requirements, which can include but are not limited to manually starting the action of the device according to the actual detection operation needs, or inputting signals in the form of analog signals, digital signals or network signals to the multifunctional strip steel detection platform, so in some embodiments, the multifunctional strip steel detection platform shown in the above embodiment can also include a controller, a control system or a third-party control end electrically connected to each component, for unified control of the multifunctional strip steel detection platform to detect the to-be-inspected strip steel according to the method steps in the above embodiment.

[0105] It is worth noting that the first detection requirement and the second detection requirement and the corresponding detection scheme shown in the above embodiment are only exemplary, and "first" and "second" are only used to distinguish different types of detection requirements, and are not used to limit the setting order or number of polishing detection in steps S610-S650 and tolerance detection in steps S710-S740. In this embodiment, for example, when the to-be-inspected strip steel is conveyed to the polishing end, therefore in other embodiments, according to the actual detection requirement or the result of analysis and processing based on the data processing device, steps S610-S650 and steps S710-S740 can be executed once, repeatedly, multiple times or not executed.

[0106] In this embodiment, the step of controlling the position of the water platform surface and / or the polishing end for detection operation includes: obtaining the thickness parameter of the to-be-inspected strip steel, and controlling the rising height of the water platform surface according to the thickness parameter. The thickness parameter can be manually input or measured in real time, or obtained based on information such as production logs issued by the production line of the to-be-inspected strip steel during production, or by sending information requests to the production line or dispatching party and obtaining based on the feedback received from the production line or dispatching party. It can be understood that since the size and model of the to-be-inspected strip steel are different, the rising height of the water platform surface is controlled according to the thickness parameter, which is beneficial to reduce the impact of the water platform surface on the to-be-inspected strip steel.

[0107] In the embodiment, based on the first detection requirement, the step of laying the felt on the water platform surface comprises:

[0108] obtaining a preset tension data table and a plate shape parameter of the to-be-inspected strip steel, the tension data table storing a plurality of preset plate shapes and preset felt tensions corresponding to each other;

[0109] matching the plate shape parameter with the tension data table, determining a preset plate shape matched with the plate shape parameter as a target plate shape, and taking a preset felt tension corresponding to the target plate shape as a target tension;

[0110] adjusting the pulling force of the winch according to the target tension, so that the tension of the felt reaches the target tension.

[0111] For the above steps, it is worth noting that different types of to-be-inspected strip steels often need to match different felt tensions during polishing due to different forming process conditions, material properties and other factors. In the embodiment, the tension data table refers to a data table determined in advance, an empirical value or an industry standard, which includes the felt tension required by the to-be-inspected strip steel under different plate shape parameters. By obtaining the plate shape parameter of the to-be-inspected strip steel, the felt tension that best meets the current polishing requirements of the to-be-inspected strip steel, i.e. the target tension, can be matched in the tension data table.

[0112] In the embodiment, after the step of lowering the polishing end head and pressing the to-be-inspected strip steel, comprises:

[0113] obtaining a polishing pressure interval of the to-be-inspected strip steel;

[0114] detecting the current pressure of the polishing end head;

[0115] based on the current pressure, if the current pressure is less than the minimum value of the polishing pressure interval, increasing the driving force for driving the polishing end head to descend, if the current pressure is in the polishing pressure interval, keeping the driving force for driving the polishing end head to descend, and if the current pressure is greater than the maximum value of the polishing interval, reducing the driving force for driving the polishing end head to descend.

[0116] For the above steps, it can be understood that different types of steel strips to be inspected need to match different polishing pressures according to different forming process conditions, material properties and other factors. Under the polishing pressure, the steel strip to be inspected can expose the possible defects to the greatest extent. The polishing pressure is often determined in advance through industry standards, experience values or test calibration, that is, the polishing pressure interval. The specific acquisition method belongs to the prior art in the art and is therefore not limited. The current pressure of the polishing end can be measured in real time by, for example, setting a pressure sensor on the polishing end. It is determined whether the current pressure reaches the polishing pressure interval suitable for polishing, and the driving force for the polishing end to drop is adjusted based on the determination result, so that the current pressure is finally located in the polishing pressure interval, which is beneficial to further improve the polishing effect and further improve the defect detection accuracy of the steel strip to be inspected.

[0117] In the present embodiment, the analysis and processing performed by the data processing device specifically includes the following steps:

[0118] A preset database is obtained, which stores a plurality of corresponding relationships between defect features and defect categories.

[0119] Based on the detection data received by the data processing device, the defect features in the database are matched to determine the target defect category to which the detection data belongs from the defect categories as at least part of the detection results.

[0120] For the above steps, it can be understood that the known defect features of different steel strips to be inspected have been stored in the database, and the defect categories corresponding to the defect features, that is, the defect types, names, causes and other data. After the data processing device receives the detection data collected by the data acquisition device, the detection data is matched in the database. According to the same defect features matched, the defect categories corresponding to the defect features can be found, so as to determine the defects of the steel strip to be inspected. Compared with the traditional manual visual recognition, the above embodiment finds the defects of the steel strip to be inspected by automatic matching, which is beneficial to improve the defect analysis efficiency and can effectively meet the synchronous detection needs of various detection needs.

[0121] As described above, the steel strip detection method provided by the present application collects mechanisms for functions such as felt laying, polishing, data acquisition and data processing in the same detection platform, so that multiple types of detection operations can be performed on the steel strip at the same station. The detection form of the multi-station operation in the prior art is effectively improved, the space occupation is greatly reduced, and the labor cost of steel strip detection is reduced. At the same time, multiple types of detection are completed at the same station, and the product defects are analyzed in real time by the data processing device to replace manual judgment, effectively reducing the risk of missed detection and judgment, and reducing the loss of waste or defective products.
