Description

Technical Field

[0001] This invention belongs to the field of industrial testing, and in particular relates to an intelligent testing device for sprue brick blanks. Background Technology

[0002] The sprue brick is a key refractory component in the continuous casting process for controlling the flow of molten steel. Before entering the high-temperature sintering process, the formed brick blanks (green blanks) must undergo rigorous appearance quality inspection to screen for surface defects such as cracks, missing corners, and porosity, preventing defective products from flowing into subsequent processes and causing energy waste and safety hazards. Currently, the refractory materials industry mainly relies on manual visual inspection or traditional fixed visual inspection stations for the appearance inspection of sprue brick blanks.

[0003] To reduce damage during transport, an automated workflow solution with independent inspection stations is also adopted. This involves the brick blanks being directly fed into a fixed vision inspection device via conveyor belt or robotic arm after demolding. While this solution reduces manual contact, it still has shortcomings. First, the brick blanks must undergo a transport path between the press and the inspection station, during which defects cannot be detected in time. If the press mold malfunctions, it will lead to a batch of defective products without real-time warning. Second, the fixed inspection station requires independent floor space and loading / unloading mechanisms, increasing the complexity of the production line layout and construction costs.

[0004] In recent years, with the widespread adoption of Automated Guided Vehicles (AGVs) in refractory material production lines, a technological concept has emerged: directly mounting vision inspection modules onto AGVs to simultaneously perform inspections during transportation. However, existing AGV integrated inspection solutions, when dealing with scenarios involving the simultaneous transport of multiple brick blanks, require the design of multiple inspection cameras for each brick blank, leading to a surge in AGV onboard hardware costs and a heavy burden on power supply and data processing. In summary, existing technologies have consistently struggled to achieve a balance between transporting multiple brick blanks and low-cost inspection in the integrated AGV transport and inspection application of refractory brick blanks. Therefore, an intelligent inspection device for refractory brick blanks is proposed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent detection device for sprue brick blanks, which aims to solve the problems mentioned in the background art.

[0006] The present invention is implemented as follows: an intelligent inspection device for sprue brick blanks includes an AGV chassis, and further includes: The power box is located on the AGV chassis, and a receiving platform is fixedly installed on the top of the power box; A turntable and multiple workpiece tables for supporting brick blanks, wherein the turntable is rotatably positioned at the center of the receiving platform, and the multiple workpiece tables are distributed on the outside of the turntable and are all rotatably positioned at the edge of the receiving platform. A vision inspection module located on a turntable, the vision inspection module being used only to inspect brick blanks on a single workpiece table; The power box is used to drive the turntable and multiple workpiece tables to rotate, and the rotation of the turntable and the workpiece tables is asynchronous.

[0007] Preferably, the receiving platform has multiple circular mounting holes, and the workpiece table includes a frustum rotatably connected in the circular mounting holes. A positioning column made of flexible material is mounted on the frustum, and the positioning column itself is arranged in a vertical direction. The shape of the positioning column matches the shape of the inner hole of the brick blank.

[0008] Preferably, the bottom of the workpiece stage is equipped with a drive wheel located inside the power box, and the power box is also provided with a turntable that cooperates with multiple drive wheels. The turntable is provided with a hollow structure, and a drive ring is fixedly connected to the inner side of the turntable. The bottom of the turntable is equipped with a drive shaft located inside the power box. The drive shaft is located inside the drive ring. The power box is equipped with a drive control unit with dual outputs. The dual outputs of the drive control unit are respectively connected to the drive shaft and the drive ring, and the input end of the drive control unit is connected to the AGV chassis.

[0009] Preferably, the side of the turntable is in contact with the side of the drive wheel, and limit rings are fixedly connected to the edges of the upper and lower surfaces of the turntable. When the turntable rotates, the multiple drive wheels rotate synchronously.

[0010] Preferably, the drive control component is a dual electromagnetic clutch, with its two output ends being coaxial inner and outer shaft structures. The inner shaft output end is connected to the drive shaft, and the outer shaft output end is connected to the drive ring via a transmission gear.

[0011] Preferably, the visual inspection module includes two protective columns located on a turntable and stacked axially. A transparent window is provided on one side of the protective column, and a camera component corresponding to the transparent window is provided inside the protective column.

[0012] Preferably, the camera assembly is an area array camera, and a micro motor is fixedly connected to the top of the lower protective column, the output end of the micro motor being connected to another protective column; When a single area array camera can capture all images of the brick along its height direction, a micro motor is used to make the two area array cameras face away from each other. When a single area array camera cannot capture all images of the brick along its height direction, a micro motor is used to make the two area array cameras face the same direction.

[0013] Preferably, a rechargeable lithium battery is also integrated inside the lower protective column, which is used to power the micro motor.

[0014] The intelligent detection device for sprue brick blanks provided in this embodiment of the invention has the following advantages: This equipment integrates inspection functions into the AGV transportation process, achieving integrated transportation and inspection. After the brick blanks exit the press mold, they can undergo rough inspection of the outer circular surface during transport without additional transfer to a separate inspection station, significantly shortening the quality feedback chain. When abnormalities occur in the press mold, they can be detected and alerted immediately. Through a dual-layer motion design of turntable revolution and workpiece table rotation, the vision inspection module is limited to operating only on a single workpiece table. The brick blank only needs to rotate in place during inspection, minimizing mechanical disturbance and significantly improving the safety of brick blank transportation and inspection. This equipment requires only one vision inspection module to meet the sequential inspection needs of multiple brick blanks' outer circular surfaces. Most importantly, this equipment embodies the industrial concept of tiered inspection, completing only a preliminary screening inspection of the outer circular surface during transport, while reserving more demanding inspection tasks such as those on the inner wall and upper and lower end faces for subsequent fixed stations. This not only simplifies the structure of the AGV side to the extreme, eliminating the need to integrate complex endoscopic probes, flipping mechanisms, or precision positioning devices, thus balancing cost control and operational reliability, but also allows the AGV's rough inspection to intercept brick blanks with serious appearance defects in advance, preventing them from occupying the resources of subsequent fine inspection stations. As a result, the best balance is achieved between production line logistics efficiency, comprehensive inspection, and economical equipment investment. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0019] like Figure 1 and Figure 2 As shown, an intelligent inspection device for sprue brick blanks, provided in one embodiment of the present invention, includes an AGV chassis 1, and further includes: The power box 2 is located on the AGV chassis 1, and a receiving platform 3 is fixedly installed on the top of the power box 2; A turntable 4 and multiple workpiece platforms 5 for supporting brick blanks. The turntable 4 is rotatably positioned at the center of the receiving platform 3, and the multiple workpiece platforms 5 are distributed on the outside of the turntable 4 and are all rotatably positioned at the edge of the receiving platform 3. The vision inspection module 6 is located on the turntable 4 and is used only to inspect brick blanks on a single workpiece table 5. The power box 2 is used to drive the turntable 4 and multiple workpiece tables 5 to rotate, and the rotation of the turntable 4 and the workpiece tables 5 is not synchronized.

[0020] In one embodiment of the invention, the device uses multiple rotatable workpiece platforms 5 to support brick blanks, which are vertically oriented. During the movement of the AGV chassis 1, inspection is also performed. The power unit 2 drives the turntable 4 and the multiple workpiece platforms 5 to rotate asynchronously. The turntable 4 drives the vision inspection module 6 on it to rotate, allowing the vision inspection module 6 to sequentially align with the brick blanks supported on each workpiece platform 5. Simultaneously, the aligned workpiece platform 5 drives the brick blank to rotate around its vertical axis, thus enabling a single vision inspection module 6 to complete the acquisition of a complete 360° image of the outer surface of the brick blank. Firstly, this device integrates the inspection function into the AGV transportation process, achieving integrated transportation and inspection. After the brick blank exits the press mold, it does not need to be transported to an independent inspection station; a rough inspection of the outer surface can be completed during transportation, greatly shortening the quality feedback chain. When an abnormality occurs in the press mold, it can be detected and warned immediately, effectively preventing the generation of batch defective products. Secondly, this equipment utilizes a unique motion design where the turntable 4 revolves and the workpiece table 5 rotates, limiting the vision inspection module 6 to operate only on a single workpiece table 5. This completely eliminates the traditional approach of relying on the entire tray to revolve around the camera. This design ensures that the receiving platform 3, which carries multiple brick blanks, remains stationary. The brick blanks only need to rotate in place during inspection, minimizing mechanical disturbances and reducing the risk of hidden damage caused by centrifugal force and vibration during rotation. This significantly improves the safety of brick blank transportation and inspection. Furthermore, this equipment only requires one vision inspection module 6 on the AGV side to meet the sequential inspection needs of the outer surfaces of multiple brick blanks. This greatly reduces the number of onboard cameras and the associated power supply and data processing hardware. While reducing the manufacturing cost and weight of the AGV, it also alleviates the energy burden on the onboard battery, enabling the AGV to have a longer driving range and better carrying efficiency. Most importantly, this equipment only performs a preliminary screening inspection of the outer circular surface during transportation, leaving the inspection of the inner wall, upper and lower end faces, and other areas requiring higher positioning accuracy and environmental conditions to be completed at subsequent fixed stations. This distributed inspection architecture simplifies the AGV side structure to the extreme, eliminating the need for complex endoscopic probes, flipping mechanisms, or precision positioning devices, thus balancing cost control and operational reliability. Furthermore, the AGV's preliminary inspection can intercept brick blanks with serious appearance defects in advance, preventing them from occupying valuable resources at subsequent fine inspection stations. The fine inspection stations, on the other hand, can perform a more precise and comprehensive evaluation of the brick blanks under static conditions, thereby achieving an optimal balance between production line logistics efficiency, comprehensive inspection, and economical equipment investment.

[0021] In one example of the present invention, such as Figure 3 and Figure 4As shown, the receiving platform 3 has multiple circular mounting holes 7. The workpiece stage 5 includes a frustum 501 rotatably connected within the circular mounting holes 7. A flexible positioning post 502 is mounted on the frustum 501, and the positioning post 502 is vertically oriented. The shape of the positioning post 502 matches the shape of the inner hole of the brick blank. The circular mounting holes 7 are preferably stepped holes, and rolling bearings or sliding bushings can be embedded in the holes. The workpiece stage 5 includes a frustum 501, the bottom of which is rotatably connected to a bearing or bushing within the circular mounting holes 7 via a rotating shaft, thereby enabling the frustum 501 to achieve smooth, low-resistance rotation on the receiving platform 3. A vertically extending positioning post 502 is fixedly mounted on the top of the frustum 501, and the positioning post 502 is used to support and fix the sprue brick blank to be tested. The outer contour of the positioning post 502 matches the inner hole shape of the brick blank. By fitting the brick blank onto the positioning post 502 from top to bottom, rapid positioning and circumferential limiting of the brick blank on the workpiece stage 5 can be achieved. The positioning post 502 can be made of industrial-grade silicone, thermoplastic polyurethane elastomer, foamed polyurethane, or soft rubber, and its Shore hardness should be controlled within the range of A30 to A70. Since the sprue brick blank is in a green state before sintering, its mechanical strength is extremely low, its texture is soft, and its surface is prone to powdering. If a rigid positioning post 502 such as metal or hard plastic is used, the brick blank is very likely to suffer end face damage or inner hole wall scratches due to hard contact during the fitting process. Furthermore, flexible materials have good damping characteristics, which can absorb the slight vibrations caused by the start and stop of the motor or the gaps in the transmission mechanism when the brick blank rotates, so that the brick blank always maintains a stable posture during rotation, which is beneficial for image acquisition. In addition, for slight fluctuations in the inner hole size of different batches of brick blanks, the flexible positioning column 502 can adaptively compensate through its own slight deformation, without the need for frequent replacement of positioning fixtures.

[0022] like Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the bottom of the workpiece stage 5 is equipped with drive wheels 8 located inside the power housing 2. The power housing 2 is also equipped with a turntable 9 that cooperates with multiple drive wheels 8, and the turntable 9 is provided with a hollow structure. A drive ring 10 is fixedly connected to the inner side of the turntable 9. The bottom of the turntable 4 is equipped with a drive shaft 11 located inside the power housing 2. The drive shaft 11 is located inside the drive ring 10. The power housing 2 is equipped with a drive control component 12 with dual output ends. The dual output ends of the drive control component 12 are respectively connected to the drive shaft 11 and the drive ring 10, and the input end of the drive control component 12 is connected to the AGV chassis 1.

[0023] In one embodiment, the side of the turntable 9 contacts the side of the drive wheel 8, and limit rings 13 are fixedly connected to the edges of the upper and lower surfaces of the turntable 9. When the turntable 9 rotates, the multiple drive wheels 8 rotate synchronously. The drive control unit 12 is a dual electromagnetic clutch with two coaxial inner and outer shaft structures at its two output ends. The inner shaft output end is connected to the drive shaft 11, and the outer shaft output end is connected to the drive ring 10 via a transmission gear. During the inspection operation, the power input of the AGV chassis 1 is sent to the drive control unit 12. The drive control unit 12 has two independently controllable output ends, one of which is connected to the drive shaft 11, and the other is connected to the drive ring 10 via a transmission gear. When the vision inspection module 6 needs to switch the target workpiece stage 5, the drive control unit 12 controls the output end connected to the drive shaft 11 to rotate, causing the turntable 4 to rotate so that the vision inspection module 6 is aligned with the next workpiece stage 5 to be inspected. During this process, the output end connected to the drive ring 10 remains stationary, and the workpiece stage 5 does not rotate. After the turntable 4 is in position, the output end connected to the drive shaft 11 stops or remains braked, while the output end connected to the drive ring 10 begins to move, driving the turntable 9 to rotate. The turntable 9 drives the workpiece stage 5 currently at the inspection station to rotate through friction or meshing between its side circumference and each drive wheel 8, thereby causing the brick blank fitted on it to rotate around the vertical axis, cooperating with the vision inspection module 6 to complete the acquisition of the outer circular surface image. After one brick blank is inspected, the drive control component 12 switches again, and the turntable 4 revolves to send the vision inspection module 6 to the next workpiece stage 5. The turntable 9 and the multiple drive wheels 8 are connected by a centralized transmission and axial constraint with a limiting ring 13, ensuring that the turntable 9 can smoothly and synchronously drive each drive wheel 8 to rotate. The transmission is smooth and reliable, and the driving torque obtained by each workpiece stage 5 is uniform, ensuring the consistency of the brick blank's rotation speed and providing stable imaging conditions for vision inspection.

[0024] One specific implementation of the drive control unit 12 is a dual electromagnetic clutch, whose two output ends are constructed as coaxial inner and outer shafts. The inner shaft output end is connected to the drive shaft 11, and the outer shaft output end is connected to the drive ring 10 via a transmission gear. The independent start and stop of the two motion paths are achieved by controlling the on and off states of the two sets of electromagnetic coils. Alternatively, the drive control unit 12 can also be a drive module composed of two independent servo motors. The first servo motor is directly connected to the drive shaft 11, and the second servo motor is connected to the drive ring 10 via a reducer. The two motors are time-coordinated by the same motion controller, and the step-by-step movements of the revolution of the turntable 4 and the rotation of the workpiece table 5 can be flexibly realized by triggering electrical signals sequentially.

[0025] like Figure 3As shown, in a preferred embodiment of the present invention, the visual inspection module 6 includes two protective columns 601 located on the turntable 4 and stacked axially. A transparent window 602 is provided on one side of the protective column 601, and a camera component corresponding to the transparent window 602 is provided inside the protective column 601. The camera component is an area scan camera.

[0026] In one case of this embodiment, such as Figure 5 As shown, an intelligent detection method for sprue brick blanks is provided, the method comprising: S10, Target Positioning and Image Acquisition: Drive controller 12 controls turntable 4 to revolve, so that vision inspection module 6 is aligned with target workpiece stage 5 carrying brick blank to be inspected. Then, it controls target workpiece stage 5 to rotate, causing brick blank to rotate uniformly around its vertical axis for one revolution. During the rotation of brick blank, the area array camera in vision inspection module 6 continuously acquires rectangular image sequences of the brick blank surface at a fixed frame rate.

[0027] S20, Image preprocessing: The acquired rectangular image sequence is processed frame by frame to extract the region of interest, perform grayscale correction and filtering to obtain a processed image sequence containing only the effective area of ​​the brick surface.

[0028] S30, Outer Circular Surface Panoramic Stitching: Based on the angular velocity of the brick's rotation and the acquisition frame rate of the area array camera, the spatial correspondence between adjacent frame images is determined; feature points in the overlapping area of ​​adjacent frame images are extracted, and the homography transformation matrix between images is calculated through a feature matching algorithm. The processed image sequences are then stitched together sequentially to generate an unfolded panoramic image of the outer circular surface of the brick.

[0029] S40, Defect Detection and Result Output: The panoramic image is input into a pre-trained deep learning model for defect detection. The model identifies and labels appearance defects such as cracks, pores, inclusions, and missing corners in the image. It outputs the defect type, location coordinates, and size information, and determines the quality grade of the brick blank according to the preset acceptance criteria.

[0030] The above method achieves comprehensive coverage inspection of the outer surface of cylindrical sprue brick blanks. Compared with the traditional hard stitching method of line-scanning with a linear array camera, this method uses a planar array camera combined with software stitching, which significantly reduces the accuracy requirements of the camera installation angle and eliminates the need for complex optical path alignment mechanisms, resulting in a simpler equipment structure. Furthermore, the rectangular image itself contains rich two-dimensional texture information, making the identification of local defects such as cracks and pores more intuitive and reliable.

[0031] like Figure 3As shown, based on the above embodiment, a micro motor 14 is fixedly connected to the top of the lower protective column 601, and the output end of the micro motor 14 is connected to another protective column 601. When a single area array camera can capture all the images of the brick along its height direction, the micro motor 14 is used to make the two area array cameras face away from each other. When a single area array camera cannot capture all the images of the brick along its height direction, the micro motor 14 is used to make the two area array cameras face the same direction.

[0032] In one embodiment, the image acquisition step specifically includes: S11, Brick height recognition: Before the inspection begins, a preliminary scan is performed by the visual inspection module 6 to obtain the height value of the brick to be inspected.

[0033] S12, Detection mode determination: The acquired brick height value is compared with the effective imaging height of a single area array camera; if the brick height value is less than or equal to the effective imaging height, it is determined to enter the dual-channel parallel detection mode; if the brick height value is greater than the effective imaging height, it is determined to enter the single-channel stitching detection mode.

[0034] S13, Camera configuration adjustment: When the dual-channel parallel mode is determined, the micro motor 14 drives the upper protective column 601 to rotate, so that the transparent windows 602 of the upper and lower area array cameras face opposite directions (at a 180° angle); when the single-channel splicing mode is determined, the micro motor 14 drives the upper protective column 601 to rotate, so that the transparent windows 602 of the upper and lower area array cameras face the same direction.

[0035] S14, perform image acquisition in the corresponding mode: In dual-channel parallel mode, two area array cameras independently acquire rectangular image sequences of their respective brick blanks, and the two sets of image data are transmitted in parallel to the processing unit for subsequent stitching and detection; In single-channel stitching mode, two area array cameras are aligned with the same target workpiece stage 5, with the upper area array camera covering the upper half of the brick blank and the lower area array camera covering the lower half of the brick blank, and the fields of view of the two area array cameras have a preset proportion of overlap in the middle of the brick blank. During the rotation of the workpiece stage 5, the two cameras synchronously acquire image sequences, and after the upper and lower sets of image sequences are stitched together, they are then fused into a complete rectangular image sequence through feature matching of the overlap area.

[0036] This embodiment introduces an adaptive brick height determination and a switchable phase structure mechanism, enabling the vision inspection module 6 to flexibly select the optimal working mode based on the actual size of the brick. When inspecting bricks with shorter heights, the dual-channel parallel mode can simultaneously acquire the outer circular surface of two bricks, reducing the average inspection time per piece by nearly half and significantly improving the inspection efficiency during AGV transportation. When inspecting bricks with longer heights, the single-channel stitching mode achieves complete coverage of the entire height range through the connection of the fields of view of two area array cameras, solving the problem that the vertical resolution of a single area array camera is insufficient to cover tall bricks. Furthermore, the overlapping area between the two images provides sufficient feature matching basis for subsequent stitching, ensuring the integrity and continuity of the panoramic unfolded image. The rotation of the micro motor 14 is independently powered by a lithium battery located in the lower protective column 601, eliminating the need for external cables and avoiding the wire entanglement problem caused by the overall rotation of the protective column 601 with the turntable 4.
