Description

Technical Field

[0001] This invention relates to the field of metal sheet rolling technology, specifically to a metal sheet rolling equipment with detection function. Background Technology

[0002] In the rolling production of sheet metal, the stability of the rolling process and the surface quality of the rolled sheet directly determine the grade and added value of the final product. Existing metal rolling equipment, especially multi-stand continuous rolling mills, are prone to producing quality defects such as peeling, inclusions, scratches, indentations, and roll marks on the surface of the rolled sheet during high-speed rolling due to factors such as roll wear, uneven process lubrication, and the extension of incoming material defects.

[0003] Currently, most rolling mills lack online quality feedback capabilities and rely primarily on independent downstream testing instruments or offline sampling inspections for quality control. This approach suffers from the following technical drawbacks:

[0004] Lack of real-time feedback: The independent detection device is separated from the rolling mill control system, and the quality data cannot be fed back to the rolling mill parameter adjustment (such as roll gap, tension, rolling force) in real time. As a result, defects are only discovered after they have been generated in batches, and the adjustment is delayed.

[0005] Modern rolling mills tend to have a compact layout, and downstream independent inspection devices require additional installation space. On short-process or compact rolling mill production lines, it is difficult to install them close to the mill exit, resulting in a long inspection distance and an inability to reflect rolling quality problems in a timely manner.

[0006] The outlet side of the rolling mill contains a large amount of water mist, iron oxide scale, oil mist, etc., which will cause serious contamination to any nearby detection unit. This makes it impossible for traditional rolling equipment to reliably integrate optical detection elements, making it difficult to achieve "rolling and testing at the same time". Summary of the Invention

[0007] The purpose of this invention is to provide a metal sheet rolling equipment with detection function to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a metal plate rolling equipment with detection function, including a conveyor belt, a rolling mill group fixedly installed at one end of the conveyor belt, a vision inspection mechanism fixedly installed at the end of the rolling mill group away from the conveyor belt, the rolling mill group including a uniformly distributed cold rolling mill, the cold rolling mill including a work roll one and a work roll two, and a metal plate disposed between the work roll one and the work roll two;

[0009] The visual inspection mechanism includes an upper inspection component and a lower inspection component respectively disposed on both sides of the metal plate, and the upper inspection component and the lower inspection component are symmetrically arranged about the metal plate;

[0010] Both the upper and lower detection components include a displacement mechanism and a detection component. The output end of the displacement mechanism is connected to the detection component, and an air circuit module is installed on the outside of the detection component. Through the cooperation between the displacement mechanism, the air circuit module, and the detection component, high-precision online quality detection of the metal plate is performed during the rolling process. The detection data is fed back to the rolling equipment control system to achieve real-time adjustment.

[0011] The rolling mill has a vision inspection mechanism integrated into its exit-side archway via a fixed plate, forming a rigid connection with the mill body. The upper and lower inspection components are connected by support columns and arranged symmetrically about the rolling line, respectively for inspecting the upper and lower surfaces of the rolled plate. Both the upper and lower inspection components include a displacement mechanism, a pneumatic module, and inspection components, enabling the entire equipment to have online inspection capabilities at the exit side.

[0012] Furthermore, the visual inspection mechanism also includes a fixed plate and a support column. A fixed plate is fixedly connected to the side of the cold rolling mill away from the conveyor belt, and the fixed plate is fixedly connected to the upper inspection component. A support column is fixedly connected between the upper inspection component and the lower inspection component.

[0013] The cold rolling mill includes a servo motor, a gearbox, a first drive shaft, a second drive shaft, a first support roller, and a second support roller. The output end of the servo motor is fixedly connected to the gearbox, and the output end of the gearbox is fixedly connected to the first drive shaft and the second drive shaft. A frame is provided on the side of the first drive shaft and the second drive shaft away from the gearbox. A first work roller is fixedly connected to the end of the first drive shaft away from the gearbox, and a second work roller is fixedly connected to the end of the second drive shaft away from the gearbox. A first support roller is provided on the upper side of the first work roller, and a second support roller is provided on the lower side of the second work roller. The first work roller, the second work roller, the first support roller, and the second support roller all rotate within the frame.

[0014] The cold rolling mill includes work roll 1, work roll 2, and their corresponding support roll 1 and support roll 2 arranged sequentially along the direction of metal sheet movement. Work roll 1 and work roll 2 are driven by servo motors through gearboxes, drive shaft 1, and drive shaft 2 to roll the metal sheet.

[0015] Furthermore, the displacement mechanism includes an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The X-axis moving component is fixedly connected to the side of the fixed plate away from the cold rolling mill. The Y-axis moving component is fixedly connected to the side of the X-axis moving component away from the fixed plate. The Z-axis moving component is fixedly connected to the output end of the Y-axis moving component.

[0016] Furthermore, the X-axis moving assembly includes a second fixed plate, a rack, a gear, a rotating shaft, a connecting plate, a first cable chain, a first motor, a first pulley, a belt, and a second pulley. Two sets of second fixed plates are fixedly connected to the side of the first fixed plate away from the cold rolling mill. A rack is fixedly connected to the upper side of the second fixed plate, and a gear meshes with the outer side of the rack. A rotating shaft is fixedly connected between the two sets of gears. A second pulley is fixedly connected to the middle of the rotating shaft. A first pulley is disposed on the upper side of the second pulley. A belt is drivingly connected to the outer sides of the first and second pulleys. A first motor is disposed on one side of the first pulley, and the output end of the first motor is fixedly connected to the first pulley. A connecting plate is fixedly connected to one side of one set of second fixed plates, and a first cable chain is fixedly connected to the side of the connecting plate away from the metal plate.

[0017] The second fixing plate of the X-axis moving assembly is fixed on the first fixing plate. When the motor starts, it drives the first pulley to rotate, which in turn drives the second pulley to rotate via a belt. The second pulley is fixedly connected to the rotating shaft, and gears are fixedly installed at both ends of the rotating shaft. The gears mesh with the rack fixed on the second fixing plate.

[0018] When the motor rotates forward, the gear rolls along the rack, driving the entire detection unit to move along the X-axis (rolling direction), bringing the detection components closer to or further away from the roll exit. This adjustment is used to adapt to different rolling speeds and sheet shapes, ensuring that the detection position is always in the section where the sheet shape is most stable after rolling.

[0019] Furthermore, the Y-axis moving assembly includes a housing, a sliding block, a lead screw, a motor, a mounting bracket, and a cable chain. Two sets of mounting seats are provided on the outer side of the rotating shaft, and the rotating shaft rotates within the mounting seats. The outer side of the motor is fixedly connected to the mounting seat. The mounting bracket is fixedly connected to the side of the mounting seats away from the fixed plate. The other end of the cable chain is fixedly connected to the mounting bracket. The housing is fixedly connected to the inner side of the mounting bracket. The motor is fixedly connected to one end of the housing. The output end of the motor is fixedly connected to the lead screw. The other end of the lead screw is rotatably connected to the inner wall of the housing. The cable chain is fixedly connected to the side of the mounting bracket away from the metal plate. Two sets of sliding blocks are threadedly connected to the outer side of the lead screw, and the sliding blocks slide inside the housing.

[0020] The housing of the Y-axis moving assembly is fixedly connected to the mounting bracket. Motor 2 starts, driving lead screw 1 to rotate. Lead screw 1 is threadedly connected to sliding block 1, which slides within the guide rail of housing 1.

[0021] When motor 2 rotates forward, lead screw 1 drives sliding block 1 to move along the Y-axis (transverse direction perpendicular to the rolling direction), aligning the detection component with the centerline or edge detection position of the rolled plate. This adjustment is linked to the mill width automatic alignment system to ensure that the detection field of view always covers the effective width of the rolled plate.

[0022] Furthermore, the Z-axis moving assembly includes a base plate, a housing, a motor, a lead screw, a cable chain, and a sliding block. The base plate is fixedly connected to the side of the sliding block away from the fixed plate. The housing is fixedly connected to the side of the base plate away from the fixed plate. The motor is fixedly connected to the side of the housing away from the metal plate. The lead screw is fixedly connected to the output end of the motor. The other end of the lead screw is rotatably connected to the inner wall of the housing. The sliding block is threaded to the outer side of the lead screw. The sliding block slides inside the housing. The cable chain is fixedly connected to the end of the base plate away from the metal plate. The other end of the cable chain is fixedly connected to the sliding block. The other end of the cable chain is fixedly connected to a set of the base plates.

[0023] The base plate of the Z-axis moving assembly is fixedly connected to the sliding block one of the Y-axis moving assembly. Motor three starts, driving lead screw two to rotate. Lead screw two is threadedly connected to sliding block two, which slides within the guide rail of housing two.

[0024] When the motor rotates forward, the second sliding block moves downward along the Z-axis (perpendicular to the surface of the rolled plate), bringing the detection component closer to the surface of the rolled plate; when rotating in reverse, it moves upward, away from the surface of the rolled plate. This adjustment is used to precisely control the detection distance (usually 5-20mm), ensuring image clarity while avoiding collisions with the rolled plate.

[0025] Furthermore, the detection assembly includes a stabilizing cavity, a CCD camera one, a CCD camera two, an LED light one, a mounting bracket, and an LED light two. A bracket is fixedly connected to the side of the sliding block two away from the mounting plate one. A stabilizing cavity is fixedly connected to the side of the bracket away from the mounting plate one. CCD camera one and CCD camera two are fixedly connected to the upper inner side of the stabilizing cavity. LED light one is fixedly connected to the inner side of the stabilizing cavity and below LED light one. Two sets of symmetrically arranged mounting brackets are fixedly connected to the inner side of the mounting brackets. LED light two is rotatably connected to the inner side of the mounting brackets. LED light one has through holes corresponding to CCD camera one and CCD camera two.

[0026] Furthermore, the gas path module includes an outer gas curtain, an inner gas curtain, and an internal gas assembly. The outer gas curtain and the inner gas curtain are fixedly installed on the outside of the stabilizing cavity, and the internal gas assembly is installed on the upper part of the stabilizing cavity.

[0027] Furthermore, the outer air curtain includes an annular air pipe, a jet head, a fixed bracket, and an air inlet pipe. Four sets of fixed brackets are fixedly connected to the outside of the stabilizing cavity. An annular air pipe is fixedly connected to one end of the fixed bracket near the metal plate. The side of the annular air pipe near the metal plate is connected to a uniformly distributed jet head. The side of the annular air pipe away from the jet head is connected to two sets of air inlet pipes.

[0028] Four sets of fixed supports for the outer air curtain are installed on the outside of the stabilization chamber. Compressed air enters the annular air pipe from the inlet pipe, which surrounds the detection window. Jet nozzles are evenly distributed on the annular air pipe. Compressed air is ejected at high speed from the jet nozzles, forming an outwardly inclined conical air curtain that blows away large particles of iron oxide scale and emulsion mist generated during the rolling process from the detection window area.

[0029] The inner air curtain includes a jet chamber, a connecting pipe, an annular square pipe, and two air inlets. The jet chamber is fixedly connected to the side of the stabilizing chamber closest to the metal plate. The jet chamber is connected to a uniformly distributed connecting pipe on the side away from the metal plate. The connecting pipe is connected to an annular square pipe on the side away from the jet chamber. Two sets of two air inlets are connected to the outer side of the annular square pipe. A honeycomb air channel is fixedly installed on the inner side of the jet chamber.

[0030] The jet chamber of the inner air curtain is fixedly installed on the side of the stabilizing chamber near the rolling plate. Compressed air enters the annular square tube from the second inlet pipe and is evenly distributed to the jet chamber through the connecting pipe. The jet chamber is equipped with honeycomb air channels to rectify the airflow into a uniform laminar flow.

[0031] The rectified airflow is ejected parallel from the slit in the jet chamber, forming a high-speed air curtain that adheres closely to the surface of the rolled plate, completely blowing away any remaining fine dust and emulsion from the detection area.

[0032] The internal air assembly includes a second jet head and an air supply pipe. The air supply pipe is located on the side of the stabilizing cavity away from the metal plate. The side of the air supply pipe close to the stabilizing cavity is connected to a uniformly distributed second jet head. The second jet head penetrates the upper sidewall of the stabilizing cavity and extends into the interior of the stabilizing cavity.

[0033] The internal air supply pipe is connected to an external air source. Clean compressed air is injected into the stabilizing chamber through the evenly distributed jet nozzles, maintaining a slight positive pressure of 200-500 Pa inside the chamber.

[0034] Positive pressure airflow leaks outward from the tiny gap (0.5-1mm) between the detection window at the bottom of the stabilizing chamber and the rolling plate, forming an inward airflow barrier that completely prevents external contaminant particles from entering the chamber. At the same time, it ensures that the temperature inside the chamber is constant and there is no condensation, creating a stable working environment for the optical components.

[0035] Furthermore, the jet head one is set at a 30-degree angle to the outside of the stabilizing cavity. LED light one is a highly uniform LED surface light source that illuminates the surface of the rolled plate vertically from directly above the window, enabling CCD camera one and CCD camera two to identify defects such as peeling, internal inclusions, and roll marks left by the rolls. After detecting defects, the rolling mill is linked to correct forming defects caused by roll gap deviation and material sticking to the roll surface by finely adjusting the reduction of work roll one and work roll two and the rolling tension. The two sets of LED lights two are high-brightness LED line light sources, installed at an acute angle of less than 15° to the surface of the rolled plate, providing oblique lighting. This allows CCD camera one and CCD camera two to use light and shadow to highlight the unevenness of the plate surface and clearly capture straight scratches and local indentations generated during the rolling process. The system provides real-time feedback on the location and depth of defects and adjusts the speed of the rolling mill drive shaft one 23 and drive shaft two 24, as well as the centering position of the rolling line, to correct surface damage caused by strip misalignment and roll collisions.

[0036] Both CCD camera one and CCD camera two are high-performance line scan cameras that continuously scan the surface of the rolled plate. The trigger signals for the cameras and light sources are provided by a high-precision rotary encoder mounted on the bearing housing of support roll two. The encoder acquires the roll speed in real time and converts it into a linear velocity signal of the rolled plate, which serves as the trigger source for the camera's line frequency, ensuring that the acquisition position of each line of images is strictly synchronized with the movement of the rolled plate, achieving pixel-level positional accuracy.

[0037] Compared with the prior art, the present invention provides a metal sheet rolling equipment with detection function, which has the following beneficial effects:

[0038] 1. This invention integrates a vision inspection mechanism directly onto the mill exit side archway, enabling the rolling equipment itself to have online quality inspection capabilities without occupying additional ground space. The inspection position is close to the work roll exit, allowing for immediate feedback after rolling is completed, providing real-time data support for closed-loop adjustment of rolling process parameters.

[0039] 2. This invention solves the problem that traditional rolling equipment cannot integrate optical detection elements by using a three-level air curtain protection structure (outer conical air curtain, inner laminar flow air curtain and internal micro positive pressure) designed for the harsh environment of the rolling site. This ensures that the detection window remains clean during long-term continuous rolling production, enabling the rolling equipment to perform stable and reliable online quality monitoring in high water mist and high dust environments.

[0040] 3. This invention integrates a three-axis servo drive mechanism (X-axis, Y-axis, and Z-axis), enabling the detection components in the rolling mill to quickly adjust their position for plates of different widths and thicknesses. It also coordinates with the mill's automatic width adjustment and roll changing operations, significantly improving the automation level and product specification adaptability of the rolling equipment. Simultaneously, the encoder installed on the support rolls achieves pixel-level synchronous triggering of rolling and double-sided synchronous imaging, providing advanced technical support for the production of high-quality metal plates.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The first work roll 25 and the second work roll 26 are driven by a servo motor 21 through a gearbox 22, a first drive shaft 23, and a second drive shaft 24 to roll the metal sheet.

[0069] Furthermore, the displacement mechanism 4 includes an X-axis moving assembly 41, a Y-axis moving assembly 42, and a Z-axis moving assembly 43.

[0070] Furthermore, the X-axis moving assembly 41 includes a second fixed plate 411, a rack 412, a gear 413, a rotating shaft 414, a connecting plate 415, a first drag chain 416, a first motor 417, a first pulley 418, a belt 419, and a second pulley 410.

The sliding blocks 422 slide inside the housing 421.

[0074] The housing 421 of the Y-axis moving assembly 42 is fixedly connected to the mounting bracket 425. The motor 424 starts and drives the lead screw 423 to rotate. The lead screw 423 is threadedly connected to the sliding block 422, which slides within the guide rail of the housing 421.

[0075] When motor 424 rotates forward, lead screw 423 drives sliding block 422 to move laterally along the Y-axis perpendicular to the rolling direction, aligning the detection component 6 with the centerline or edge detection position of the rolled plate. This adjustment is linked to the mill width automatic alignment system to ensure that the detection field of view always covers the effective width of the rolled plate.

[0076] Furthermore, the Z-axis moving assembly 43 includes a base plate 431, a housing 432, a motor 433, a lead screw 434, a cable chain 435, and a sliding block 436. The base plate 431 is fixedly connected to the side of the sliding block 422 away from the fixed plate 31. The housing 432 is fixedly connected to the side of the base plate 431 away from the fixed plate 31. The motor 433 is fixedly connected to the side of the housing 432 away from the metal plate. The output end of the motor 433 is fixed... A lead screw 434 is connected, and the other end of the lead screw 434 is rotatably connected to the inner wall of the housing 432. A sliding block 436 is threadedly connected to the outer side of the lead screw 434. The sliding block 436 slides on the inner side of the housing 432. A drag chain 435 is fixedly connected to the end of the base plate 431 away from the metal plate. The other end of the drag chain 435 is fixedly connected to the sliding block 436. The other end of the drag chain 426 is fixedly connected to a set of base plates 431.

[0077] The base plate 431 of the Z-axis moving assembly 43 is fixedly connected to the sliding block 422 of the Y-axis moving assembly 42. The motor 433 starts and drives the lead screw 434 to rotate. The lead screw 434 is threadedly connected to the sliding block 436, and the sliding block 436 slides within the guide rail of the housing 432.

[0078] When motor 3 (433) rotates forward, sliding block 2 (436) moves downward along the Z-axis perpendicular to the surface of the rolled plate, bringing the detection component 6 closer to the surface of the rolled plate; when rotating in reverse, it moves upward, away from the surface of the rolled plate. This adjustment is used to precisely control the detection distance, typically 5-20mm, to ensure image clarity while avoiding collisions with the rolled plate.

[0079] Furthermore, the detection component 6 includes a stabilizing cavity 61, a CCD camera 62, a CCD camera 63, an LED light 64, a mounting bracket 65, and an LED light 66. A bracket is fixedly connected to the side of the sliding block 436 away from the mounting plate 31. The stabilizing cavity 61 is fixedly connected to the side of the bracket away from the mounting plate 31. The CCD camera 62 and the CCD camera 63 are fixedly connected to the upper inner side of the stabilizing cavity 61. The LED light 64 is fixedly connected to the inner side of the stabilizing cavity 61 and below the LED light 64. Two sets of symmetrically arranged mounting brackets 65 are fixedly connected to the inner side of the mounting brackets 65. The LED light 66 is rotatably connected to the inner side of the mounting brackets 65. The LED light 64 has through holes corresponding to the CCD camera 62 and the CCD camera 63.

[0080] Furthermore, the air circuit module 5 includes an outer air curtain 51, an inner air curtain 52, and an internal air assembly 53. The outer air curtain 51 and the inner air curtain 52 are fixedly installed on the outside of the stabilizing cavity 61, and the internal air assembly 53 is installed on the upper part of the stabilizing cavity 61.

[0081] Furthermore, the outer air curtain 51 includes an annular air pipe 511, a jet head 512, a fixed bracket 513, and an air inlet pipe 514. Four sets of fixed brackets 513 are fixedly connected to the outside of the stabilizing cavity 61. An annular air pipe 511 is fixedly connected to one end of the fixed bracket 513 near the metal plate. The annular air pipe 511 is connected to a uniformly distributed jet head 512 on the side near the metal plate. Two sets of air inlet pipes 514 are connected to the side of the annular air pipe 511 away from the jet head 512.

[0082] Four sets of fixed supports 513 of the outer air curtain 51 are installed on the outside of the stabilizing cavity 61. Compressed air enters the annular air pipe 511 from the air inlet pipe 514, and the annular air pipe 511 is arranged around the detection window. Jet nozzles 512 are evenly distributed on the annular air pipe 511. Compressed air is ejected at high speed from the jet nozzles 512 to form an outwardly inclined conical air curtain, which blows away the large particles of iron oxide scale and emulsion mist generated during the rolling process from the detection window area.

[0083] The inner air curtain 52 includes a jet chamber 521, a connecting pipe 522, an annular square pipe 523, and an air inlet pipe 524. The jet chamber 521 is fixedly connected to the side of the stabilizing cavity 61 near the metal plate. The side of the jet chamber 521 away from the metal plate is connected to a uniformly distributed connecting pipe 522. The side of the connecting pipe 522 away from the jet chamber 521 is connected to an annular square pipe 523. Two sets of air inlet pipes 524 are connected to the outer side of the annular square pipe 523. A honeycomb air passage 525 is fixedly installed on the inner side of the jet chamber 521.

[0084] The jet chamber 521 of the inner air curtain 52 is fixedly installed on the side of the stabilizing chamber 61 near the rolling plate. Compressed air enters the annular square tube 523 from the second air inlet pipe 524 and is evenly distributed to the jet chamber 521 through the connecting pipe 522. The jet chamber 521 is equipped with a honeycomb air channel 525 to rectify the airflow into a uniform laminar flow.

[0085] The rectified airflow is ejected parallel from the slit in the jet chamber 521, forming a high-speed air curtain that adheres closely to the surface of the rolled plate, completely blowing away the remaining fine dust and emulsion from the detection area.

[0086] The internal air assembly 53 includes a second jet head 531 and an air supply pipe 532. The air supply pipe 532 is provided on the side of the stabilizing cavity 61 away from the metal plate. The side of the air supply pipe 532 near the stabilizing cavity 61 is connected to the evenly distributed second jet head 531. The second jet head 531 penetrates the upper sidewall of the stabilizing cavity 61 and extends into the interior of the stabilizing cavity 61.

[0087] The air supply pipe 532 of the internal air assembly 53 is connected to an external air source. Clean compressed air is injected into the stable chamber 61 through the evenly distributed jet nozzle 531, so that the chamber maintains a slight positive pressure of 200-500 Pa.

[0088] Positive pressure airflow leaks outward from the tiny gap of 0.5-1mm between the detection window at the bottom of the stabilizing cavity 61 and the rolling plate, forming an inward airflow barrier that completely prevents external contaminant particles from entering the cavity. At the same time, it ensures that the temperature inside the cavity is constant and there is no condensation, creating a stable working environment for the optical components.

[0089] Furthermore, the jet nozzle 512 is angled at 30 degrees outward from the stabilizing cavity 61. LED light 64, a highly uniform LED surface light source, illuminates the rolled plate surface vertically from directly above the window, enabling CCD cameras 62 and 63 to identify defects such as peeling, internal inclusions, and roll marks left by the rolls. Upon detecting defects, the rolling mill is activated, adjusting the reduction and rolling tension of work rolls 25 and 26 to correct roll gap deviations and forming defects caused by material sticking to the roll surface. Two sets of LED lights 66, high-brightness LED line light sources, are installed at an acute angle of less than 15° to the rolled plate surface, providing oblique illumination. This allows CCD cameras 62 and 63 to highlight the uneven surface morphology using light and shadow, clearly capturing straight scratches and localized indentations generated during the rolling process. The system provides real-time feedback on defect location and depth, adjusting the rotation speed of the rolling mill drive shafts 23 and 24, and the alignment of the rolling line to correct surface damage caused by strip misalignment and roll collisions.

[0090] Both CCD camera 1 (62) and CCD camera 2 (63) are high-performance line-scan cameras that continuously scan the surface of the rolled plate. The trigger signals for the cameras and light sources are provided by a high-precision rotary encoder mounted on the bearing housing of support roll 2 (28). The encoder acquires the roll speed in real time and converts it into a linear velocity signal of the rolled plate, which serves as the trigger source for the camera's line frequency, ensuring that the acquisition position of each line of images is strictly synchronized with the movement of the rolled plate, achieving pixel-level positional accuracy.

[0091] The specific usage and function of this embodiment are as follows:

[0092] The cold rolling mill 2 includes a first work roll 25, a second work roll 26, and corresponding support rolls 27 and 28 arranged sequentially along the direction of metal sheet movement. The first work roll 25 and the second work roll 26 are driven by a servo motor 21 through a gearbox 22, a first drive shaft 23, and a second drive shaft 24 to roll the metal sheet.

[0093] The rolling mill integrates a vision inspection mechanism 3 on its exit-side archway via a fixed plate 31, forming a rigid connection with the mill body. The upper inspection component 33 and the lower inspection component 34 are connected by support columns 32 and arranged symmetrically about the rolling line, respectively for inspecting the upper and lower surfaces of the rolled plate. Both the upper inspection component 33 and the lower inspection component 34 include a displacement mechanism 4, an air circuit module 5, and an inspection component 6, enabling the entire equipment to have online inspection capabilities on the exit side.

[0094] When rolling plates of different widths and thicknesses, the control system drives the displacement mechanism 4 to adjust its position in the X, Y, and Z axes according to the preset rolling schedule, so that the detection component 6 is precisely aligned with the surface of the rolled plate.

[0095] The fixing plate 411 of the X-axis moving assembly 41 is fixed on the fixing plate 31. The motor 417 starts, driving the pulley 418 to rotate, which in turn drives the pulley 410 to rotate via the belt 419. The pulley 410 is fixedly connected to the rotating shaft 414, and gears 413 are fixedly installed at both ends of the rotating shaft 414. The gears 413 mesh with the rack 412 fixed on the fixing plate 411.

[0096] When motor 417 rotates forward, gear 413 rolls along rack 412, driving the entire detection unit to move along the X-axis in the rolling direction, causing detection component 6 to move closer to or further away from the roll exit. This adjustment is used to adapt to different rolling speeds and sheet shapes, ensuring that the detection position is always in the section where the sheet shape is most stable after rolling.

[0097] The housing 421 of the Y-axis moving assembly 42 is fixedly connected to the mounting bracket 425. The motor 424 starts and drives the lead screw 423 to rotate. The lead screw 423 is threadedly connected to the sliding block 422, which slides within the guide rail of the housing 421.

[0098] When motor 424 rotates forward, lead screw 423 drives sliding block 422 to move laterally along the Y-axis perpendicular to the rolling direction, aligning the detection component 6 with the centerline or edge detection position of the rolled plate. This adjustment is linked to the mill width automatic alignment system to ensure that the detection field of view always covers the effective width of the rolled plate.

[0099] The base plate 431 of the Z-axis moving assembly 43 is fixedly connected to the sliding block 422 of the Y-axis moving assembly 42. The motor 433 starts and drives the lead screw 434 to rotate. The lead screw 434 is threadedly connected to the sliding block 436, and the sliding block 436 slides within the guide rail of the housing 432.

[0100] When motor 3 (433) rotates forward, sliding block 2 (436) moves downward along the Z-axis perpendicular to the surface of the rolled plate, bringing the detection component 6 closer to the surface of the rolled plate; when rotating in reverse, it moves upward, away from the surface of the rolled plate. This adjustment is used to precisely control the detection distance, typically 5-20mm, to ensure image clarity while avoiding collisions with the rolled plate.

[0101] Through the above-mentioned three-axis linkage adjustment, the detection component 6 can adapt to the detection requirements of rolled plates of different widths and thicknesses, and coordinate with the automatic roll changing and automatic width adjustment operations of the rolling mill without manual intervention.

[0102] Water mist, iron oxide scale, and oil mist at the rolling mill are the main sources of interference affecting optical imaging. This device is designed with a three-stage air curtain protection system to create a clean and stable detection environment around the detection component 6.

[0103] Four sets of fixed supports 513 for the outer air curtain 51 are installed on the outside of the stabilizing cavity 61. Compressed air enters the annular air pipe 511 from the inlet pipe 514, and the annular air pipe 511 is arranged around the detection window. Jet nozzles 512 are evenly distributed on the annular air pipe 511, and the jet angle of the jet nozzles 512 is set at 30 degrees to the outside of the stabilizing cavity 61.

[0104] Compressed air is ejected at high speed from the jet head 512, forming a conical air curtain that tilts outwards, blowing away large particles of iron oxide scale and emulsion mist generated during the rolling process from the detection window area.

[0105] The jet chamber 521 of the inner air curtain 52 is fixedly installed on the side of the stabilizing chamber 61 near the rolling plate. Compressed air enters the annular square tube 523 from the second air inlet pipe 524 and is evenly distributed to the jet chamber 521 through the connecting pipe 522. The jet chamber 521 is equipped with a honeycomb air channel 525 to rectify the airflow into a uniform laminar flow.

[0106] The rectified airflow is ejected parallel from the slit in the jet chamber 521, forming a high-speed air curtain that adheres closely to the surface of the rolled plate, completely blowing away the remaining fine dust and emulsion from the detection area.

[0107] The air supply pipe 532 of the internal air assembly 53 is connected to an external air source. Clean compressed air is injected into the stable chamber 61 through the evenly distributed jet nozzle 531, so that the chamber maintains a slight positive pressure of 200-500 Pa.

[0108] Positive pressure airflow leaks outward from the tiny gap of 0.5-1mm between the detection window at the bottom of the stabilizing cavity 61 and the rolling plate, forming an inward airflow barrier that completely prevents external contaminant particles from entering the cavity. At the same time, it ensures that the temperature inside the cavity is constant and there is no condensation, creating a stable working environment for the optical components.

[0109] The stabilizing cavity 61 of the detection component 6 is a box structure, in which CCD camera 1 62, CCD camera 2 63, LED lamp 1 64 and LED lamp 2 66 are fixedly installed. Among them, LED lamp 1 64 is a surface light source, and LED lamp 2 66 is a line light source. The two sets of LED lamp 2 66 are symmetrically installed through the fixing bracket 65.

[0110] Bright field lighting: LED lamp 164 is a highly uniform LED surface light source that illuminates the surface of the rolled plate vertically from directly above the window, enabling CCD camera 162 and CCD camera 263 to identify defects such as peeling skin, internal inclusions, and roll marks left by the rolls. After detecting defects, the rolling mill is linked to correct forming defects caused by roll gap deviation and material sticking to the roll surface by finely adjusting the reduction amount and rolling tension of work roll 125 and work roll 26.

[0111] Dark field lighting: Two sets of LED lights 266 are high-brightness LED line light sources. The installation angle is less than 15° with the surface of the rolled plate, and the light is obliquely illuminated. This allows CCD camera 162 and CCD camera 263 to use light and shadow to highlight the concave and convex shape of the plate surface and clearly capture straight scratches and local indentations generated during the rolling process. The system provides real-time feedback on the location and depth of defects, and adjusts the speed of the rolling mill drive shaft 123 and drive shaft 24, as well as the centering position of the rolling line, to correct the surface damage caused by strip deviation and roller collision.

[0112] Both CCD camera 1 (62) and CCD camera 2 (63) are high-performance line-scan cameras that continuously scan the surface of the rolled plate. The trigger signals for the cameras and light sources are provided by a high-precision rotary encoder mounted on the bearing housing of support roll 2 (28). The encoder acquires the roll speed in real time and converts it into a linear velocity signal of the rolled plate, which serves as the trigger source for the camera's line frequency, ensuring that the acquisition position of each line of images is strictly synchronized with the movement of the rolled plate, achieving pixel-level positional accuracy.

[0113] Synchronized with rolling speed: The encoder signal is used simultaneously for camera triggering and air curtain pressure regulation. During high-speed rolling, the air curtain flow rate is automatically increased to ensure protective effectiveness; at low speeds, the flow rate is reduced to save energy and reduce consumption.

[0114] Linked to rolling specifications: When the rolling mill changes rolling specifications, the control system automatically retrieves the preset detection position parameters according to the new specifications of plate width and thickness, and drives the displacement mechanism 4 to move to the corresponding position.

[0115] Roll changing mode: When it is necessary to replace work roll 1 25 and work roll 2 26, the control system commands the displacement mechanism 4 to retract the detection component 6 as a whole to the roll changing avoidance position, and automatically resets after the roll changing is completed.

[0116] When maintenance or replacement of optical components is required, operators can move the detection component 6 to a maintenance position outside the mill using the displacement mechanism 4. The cables and air pipes inside cable carriers 416, 426, and 435 bend as the components move, ensuring that power supply, signal, and air circuit connections are not affected.

[0117] After replacement, the displacement mechanism 4 is automatically calibrated through its precision adjustment function, so that the detection component 6 is accurately reset to its original position, ensuring consistent detection.

[0118] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
