Description

Technical Field

[0001] The present invention relates to the technical field of roll defect detection, and particularly to an intelligent image recognition and detection device for roll defects of a casting-rolling mill. Background Art

[0002] A casting-rolling mill is a short-process production device integrating casting and rolling functions, which directly converts molten metal into required workpieces through a hot continuous rolling process. During the rolling process of the roll, longitudinal or transverse scratches, cracks, pits and other defects may be formed on the roll surface, damaging the surface finish of the product and even causing spalling.

[0003] Therefore, generally after casting-rolling, manual inspection is carried out to check whether there are defects on the roll surface. If there are defects, rework is required. However, since some defects are not easily recognizable by the human eye, it may lead to missed inspections and the outflow of defective products. Moreover, long-term inspection of a large number of rolls will also cause fatigue of the human eye and further reduce the inspection accuracy. Summary of the Invention

[0004] The present invention discloses an intelligent image recognition and detection device for roll defects of a casting-rolling mill, aiming to solve the technical problems that since some defects are not easily recognizable by the human eye, it may lead to missed inspections and the outflow of defective products; and long-term inspection of a large number of rolls will also cause fatigue of the human eye and further reduce the inspection accuracy.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An intelligent image recognition and detection device for roll defects of a casting-rolling mill, comprising a bin body, a bottom support mechanism, a rotary drive mechanism and a limiting mechanism. On the inner walls of the opposite sides of the bin body, a first guiding plate and a second guiding plate are fixedly connected at the same time, and the first guiding plate and the second guiding plate are respectively distributed on both sides of the rotary drive mechanism and the bottom support mechanism. On the inner wall of the top end of the bin body, an electric linear guide rail is fixedly connected, and a first slider is movably connected on the electric linear guide rail. The bottom end of the first slider is fixedly connected with an intelligent image recognition camera;

[0007] The rotary drive mechanism comprises two rolling rods. At both ends of each rolling rod, a first support shaft is fixedly connected respectively. At the same end of the two first support shafts, a first gear is fixedly connected respectively through a universal shaft coupling, and the two first gears are simultaneously meshed with a second gear. On the outer wall of one side of the second gear, a second motor is fixedly connected. At the other ends of the two first support shafts, a bearing sleeve is rotatably connected respectively, and at the same end of each bearing sleeve, a second slider is fixedly connected respectively. The two second sliders are symmetrically movably sleeved on a bidirectional lead screw, and one end of the bidirectional lead screw is fixedly connected with a first motor;

[0008] The bottom support mechanism includes a lifting plate and a cross elevator for driving it to move upward, and the limiting mechanism includes a side abutting plate;

[0009] Two waist-shaped grooves are simultaneously penetrated through the inner walls on the opposite sides of the bin body, and two first support shafts are respectively movably connected in the waist-shaped grooves. A second bearing seat is fixedly connected to the outer wall of one side of the bin body;

[0010] Both ends of the bidirectional lead screw are rotatably connected to the second bearing seat. A first bearing seat is fixedly connected to the outer wall of the other side of the bin body, and a first gear and a second gear are simultaneously rotatably connected to the first bearing seat.

[0011] By providing a lifting plate, a side abutting plate and a rotary driving mechanism, when the roller after being cast by the casting and rolling mill falls into the bin body through the first guiding plate, it will stay on the top of the lifting plate. Then, the distance between the two rolling rods is enlarged. As the distance between the rolling rods is greater than the width of the lifting plate, at the same time, the lifting plate moves down to the bottom of the two rolling rods. At this time, the roller stays steadily between the two rolling rods and is clamped by the two rolling rods. Then, as the second motor drives the two rolling rods to rotate in the same direction, the roller can be driven to rotate uniformly and stably in the opposite direction. Through the setting of the upper intelligent image recognition camera and the electric linear guide rail, the intelligent image recognition camera can completely cover the surface of the roller to complete defect detection. In this structure, by stably placing the roller on the rolling rods, the impact of the roller on the rolling rods can be avoided, which may cause the rotation structure of the rolling rods to become loose. At the same time, the position of the roller can be quickly stabilized to ensure its uniform and stable rotation, so as to ensure the comprehensive coverage of recognition and the accuracy of recognition.

[0012] In a preferred solution, both ends of the bidirectional lead screw are rotatably connected to the second bearing seat. A first bearing seat is fixedly connected to the outer wall of the other side of the bin body, and a first gear and a second gear are simultaneously rotatably connected to the first bearing seat;

[0013] The top end of the cross elevator is fixedly connected with a bottom cover, and the top outer wall of the bottom cover is fixedly connected with a bottom plate. The top end of the bottom plate is fixedly connected with a central support, and a cavity is arranged in the central support;

[0014] A plurality of hydraulic cylinders are fixedly connected to the inner wall of the bottom end of the cavity, and the output ends of each hydraulic cylinder are respectively connected to the bottom outer wall of the lifting plate through a second hinge. One side of the lifting plate is connected to the central support through a first hinge;

[0015] The input ends of each hydraulic cylinder are respectively fixedly communicated with a hydraulic pump through a communicating pipe, and the hydraulic pump is fixedly connected in the bottom cover. A plurality of communicating pipes simultaneously pass through the central support and the bottom plate. Inner arc grooves are symmetrically arranged on the outer walls on both sides of the central support, and an arc surface is arranged on the top outer wall of the lifting plate.

[0016] By providing a bottom support mechanism, as the roller detection is completed, the cross elevator rises again until the upper lifting plate contacts the roller and drives the roller to move up and away from the rolling rod. Then the two rolling rods are recovered into the two inner arc grooves to prevent the rolling rods from being hit when the roller is unloading. Then the output ends of multiple hydraulic cylinders extend at the same time, and the upper lifting plate tilts outward, allowing the roller to fall onto the second guide plate to complete the unloading of the roller, thereby realizing automatic unloading of the roller and reducing the tediousness of manual operation.

[0017] In a preferred embodiment, the outer walls of the two sides of the side abutment plate facing each other are respectively fixedly connected with a second support shaft, and the inner wall of the top end of the bin body is fixedly connected with a support seat, and the second support shaft is rotatably connected in the support seat, and a groove is provided on one side of the side abutment plate;

[0018] An extension bracket is fixedly connected to an outer wall of one side of the warehouse body, and a gas rod is fixedly connected to an inner wall of one side of the extension bracket. The output end of the gas rod is fixedly connected to a connecting plate, and an elastic block is fixedly connected to an outer wall of one side of the connecting plate, and the elastic block is attached to the inner wall of the groove.

[0019] By setting a limiting mechanism and extending the gas rod, the elastic block can be pressed against the side abutment plate to limit the position of the side abutment plate, but it does not completely brake the plate, providing a certain buffer space to prevent the roller from colliding with the side abutment plate and pushing it back from the arc surface. In addition, based on the limitation of the second support shaft and the support seat, as the hydraulic pump retracts, the side abutment plate will be pushed to flip during the roller unloading process to avoid obstruction to the unloading process.

[0020] As can be seen from the above, an intelligent image recognition and detection device for roll defects of a casting-rolling mill includes a bin body, a bottom support mechanism, a rotary drive mechanism, and a limit mechanism. On the inner walls of the opposite sides of the bin body, a first guiding plate and a second guiding plate are fixedly connected at the same time, and the first guiding plate and the second guiding plate are respectively distributed on both sides of the rotary drive mechanism and the bottom support mechanism. On the inner wall of the top end of the bin body, an electric linear guide is fixedly connected, and a first slider is movably connected to the electric linear guide. At the bottom end of the first slider, an intelligent image recognition camera is fixedly connected; the rotary drive mechanism includes two rolling rods. At both ends of each rolling rod, a first support shaft is fixedly connected respectively. At the same end of the two first support shafts, a first gear is fixedly connected respectively through a universal shaft coupling, and the two first gears are simultaneously engaged with a second gear. On the outer wall of one side of the second gear, a second motor is fixedly connected. At the other ends of the two first support shafts, bearing sleeves are rotatably connected respectively, and at the same end of each bearing sleeve, a second slider is fixedly connected respectively. The two second sliders are symmetrically and movably sleeved on a bidirectional lead screw, and at one end of the bidirectional lead screw, a first motor is fixedly connected; the bottom support mechanism includes a lifting plate and a cross elevator for driving it to move upward, and the limit mechanism includes a side abutting plate. The intelligent image recognition and detection device for roll defects of the casting-rolling mill provided by the present invention has the technical effects of realizing intelligent recognition of roll defects of the casting-rolling mill, and at the same time ensuring the comprehensive coverage and accuracy of the recognition.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] An intelligent image recognition detection device for roll defects of a casting-rolling mill disclosed by the present invention is mainly applied to the scenario of detecting roll defects of a casting-rolling mill.

[0029] Refer to Figures 1 - 3 , an intelligent image recognition detection device for roll defects of a casting-rolling mill, including a silo body 1, a bottom support mechanism 3, a rotation driving mechanism 4 and a limiting mechanism 5. The inner walls on the opposite sides of the silo body 1 are fixedly connected with a first guiding plate 2 and a second guiding plate 7 at the same time, and the first guiding plate 2 and the second guiding plate 7 are respectively distributed on both sides of the rotation driving mechanism 4 and the bottom support mechanism 3. The inner wall of the top end of the silo body 1 is fixedly connected with an electric linear guide 10, and a first slider 9 is movably connected to the electric linear guide 10. The bottom end of the first slider 9 is fixedly connected with an intelligent image recognition camera 8;

[0030] The rotation driving mechanism 4 includes two rolling rods 406. The two ends of each rolling rod 406 are respectively fixedly connected with a first support shaft 405. The same ends of the two first support shafts 405 are respectively fixedly connected with a first gear 408 through a universal shaft coupling 407, and the two first gears 408 are simultaneously meshed with a second gear 410. The outer wall of one side of the second gear 410 is fixedly connected with a second motor 409. The other ends of the two first support shafts 405 are respectively rotatably connected with a bearing sleeve 403, and the same ends of each bearing sleeve 403 are respectively fixedly connected with a second slider 402. The two second sliders 402 are symmetrically movably sleeved on a bi-directional lead screw 401, and one end of the bi-directional lead screw 401 is fixedly connected with a first motor 404;

[0031] The bottom support mechanism 3 includes a lifting plate 304 and a cross elevator 301 for driving it to move upward. The limiting mechanism 5 includes a side abutting plate 504. When the roller after being cast by the rolling mill drops into the bin 1 through the first guiding plate 2, under the action of the side abutting plate 504, the roller will stay on the top of the lifting plate 304. At this time, the lifting plate 304 is higher than the setting height of the two rolling rods 406. Subsequently, the motor 404 drives the bidirectional lead screw 401 to rotate, driving the two sliders 402 to move outward simultaneously, expanding the distance between the two rolling rods 406. At the same time, under the action of the universal shaft coupling 407, it can ensure the separate transmission connection between the support shaft 405 and the two gears 408. As the distance between the rolling rods 406 is greater than the width of the lifting plate 304, the cross elevator 301 drives the lifting plate 304 to move downward to the bottom of the two rolling rods 406. At this time, the roller stays stably between the two rolling rods 406 and is clamped by the two rolling rods 406. Then, as the motor 409 drives the gear 410 to rotate, the two rolling rods 406 are driven to rotate in the same direction through the two gears 408, which can drive the roller to rotate uniformly and stably in the opposite direction. Furthermore, through the setting of the upper intelligent image recognition camera 8 and the electric linear guide 10, the intelligent image recognition camera 8 can completely cover the surface of the roller to complete defect detection. In this structure, by stably placing the roller on the rolling rods 406, it can avoid the roller hitting the rolling rods 406 and causing looseness of the rotating structure of the rolling rods 406. At the same time, it can quickly and stably position the roller to ensure its uniform and stable rotation, thereby ensuring the full coverage of recognition and the accuracy of recognition.

[0032] Refer to Figure 1 and Figure 3 In a preferred embodiment, two waist-shaped grooves 411 are simultaneously penetrated through the inner walls on the opposite sides of the bin 1, and the two support shafts 405 are respectively movably connected in the waist-shaped grooves 411. A bearing seat 412 is fixedly connected to the outer wall on one side of the bin 1.

[0033] Refer to Figure 2 and Figure 3 In a preferred embodiment, the two ends of the bidirectional lead screw 401 are rotatably connected to the bearing seat 412, a bearing seat 6 is fixedly connected to the outer wall on the other side of the bin 1, and the gear 408 and the gear 410 are simultaneously rotatably connected to the bearing seat 6.

[0034] Refer to Figure 5 In a preferred embodiment, the top end of the cross elevator 301 is fixedly connected with a bottom cover 302, and the outer wall of the top end of the bottom cover 302 is fixedly connected with a bottom plate 311. The top end of the bottom plate 311 is fixedly connected with a central support 309, and a cavity is arranged in the central support 309.

[0035] Referring to Figure 5 , in a preferred embodiment, a plurality of hydraulic cylinders 307 are fixedly connected to the inner wall of the bottom end of the cavity, and the output ends of each hydraulic cylinder 307 are respectively connected to the outer wall of the bottom end of the lifting plate 304 through the second hinge 306, and one side of the lifting plate 304 is connected to the central support 309 through the first hinge 305.

[0036] Referring to Figure 5 , in a preferred embodiment, the input ends of each hydraulic cylinder 307 are respectively fixedly connected to a hydraulic pump 308 through a communicating pipe, and the hydraulic pump 308 is fixedly connected to the inner part of the bottom cover 302. A plurality of communicating pipes simultaneously pass through the central support 309 and the bottom plate 311. Inner arc grooves 310 are symmetrically arranged on the outer walls on both sides of the central support 309, and an arc surface 303 is arranged on the outer wall of the top end of the lifting plate 304. After the detection of the roller is completed, the cross elevator 301 rises again until the lifting plate 304 contacts the roller and drives the roller to move upward to disengage from the rolling rod 406. Subsequently, under the drive of the bidirectional lead screw 401, the two rolling rods 406 are retracted into the two inner arc grooves 310, which is to protect the rolling rod 406 by using the central support 309 to prevent the impact on the rolling rod 406 when the roller is unloaded. Under the drive of the hydraulic pump 308, the output ends of a plurality of hydraulic cylinders 307 can be simultaneously extended. Based on the limit of the first hinge 305, the lifting plate 304 inclines outward, so that the roller can fall onto the second guiding plate 7 smoothly, completing the unloading of the roller, thereby realizing the automatic unloading of the roller and reducing the complexity of manual operation.

[0037] Referring to Figure 4 , in a preferred embodiment, second support shafts 503 are fixedly connected to the opposite outer walls of the side abutting plates 504, and a support seat 502 is fixedly connected to the inner wall of the top end of the bin body 1, and the second support shafts 503 are rotatably connected to the support seat 502, and a groove 505 is arranged on one side of the side abutting plate 504.

[0038] Referring to Figure 2 and Figure 4In a preferred embodiment, an extension bracket 501 is fixedly connected to an outer wall of one side of the warehouse body 1, and a gas rod 508 is fixedly connected to an inner wall of one side of the extension bracket 501, and an output end of the gas rod 508 is fixedly connected to a connecting plate 507, and an elastic block 506 is fixedly connected to an outer wall of one side of the connecting plate 507, and the elastic block 506 is attached to the inner wall of the groove 505. The limiting mechanism 5 mainly limits the side abutment plate 504 by attaching the inner side of the side abutment plate 504 to the outer wall of the roller to ensure that it can stand firmly on the surface of the lifting plate 304, wherein the elastic block 506 can be abutted against the side abutment plate 504 by extending the gas rod 508, and the position of the side abutment plate 504 is adjusted. The roller is limited by the setting, but it is not completely braked. A certain buffer space is given based on the elasticity of the elastic block 506. When the roller falls on the lifting plate 304, it will roll forward due to inertia. At this time, the setting of the elastic block 506 can make it stop after rolling a certain distance, and under the action of the arc surface 303, the roller is rotated until it stabilizes in the arc surface 303, avoiding the roller from colliding with the side abutment plate 504 and pushing it to reversely detach from the arc surface 303. In addition, based on the limitation of the support shaft 2 503 and the support seat 502, as the hydraulic pump 308 retracts, the side abutment plate 504 will be pushed to flip over during the roller unloading process to avoid obstruction to the unloading process.

[0039] Working principle: When the roller after casting and rolling by the casting and rolling machine passes through the guide plate 1 and falls into the warehouse body 1, the side abutment plate 504 will make the roller stay on the top of the upper lifting plate 304. At this time, the upper lifting plate 304 is higher than the setting height of the two rolling rods 406. Then, the two-way screw rod 401 is driven by the motor 1 404 to rotate, and the two sliders 2 402 are driven to move outward at the same time, so as to expand the distance between the two rolling rods 406. At the same time, under the action of the universal shaft coupling 407, the transmission connection between the support shaft 1 405 and the two gears 1 408 can be ensured. As the distance between the rolling rods 406 is greater than the width of the upper lifting plate 304, the upper lifting plate 304 is driven to move down to the bottom of the two rolling rods 406 under the action of the cross lift 301, and the roller stops stably. It stays between the two rolling rods 406 and is clamped by the two rolling rods 406, and then as the motor 2 409 drives the gear 2 410 to rotate, the two rolling rods 406 are driven to rotate in the same direction through the two gears 1 408, which can drive the roller to rotate in the opposite direction at a uniform and stable speed, and then through the setting of the upper intelligent image recognition camera 8 and the setting of the electric linear guide 10, the intelligent image recognition camera 8 can completely cover the surface of the roller to complete the defect detection. Under this structure, by stably placing the roller on the rolling rod 406, it can be avoided that the roller hits the rolling rod 406 and causes the rotating structure of the rolling rod 406 to loosen. At the same time, the position of the roller can be quickly stabilized to ensure that it can rotate at a uniform and stable speed, thereby ensuring comprehensive coverage of the recognition and ensuring the accuracy of the recognition.

[0040] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
