Description

Technical Field

[0001] This invention relates to the field of brick defect detection technology, and in particular to a device for detecting sintering cracks in earthquake-resistant lightweight bricks. Background Technology

[0002] As a key material in building structures that bears the core functions of load-bearing and earthquake resistance, earthquake-resistant lightweight bricks are susceptible to cracks that occur during the sintering process. These cracks directly threaten building safety, affect product quality, and increase the total life cycle cost. Crack detection devices are core equipment for ensuring product quality, building safety, and production efficiency during the sintering process of earthquake-resistant lightweight bricks. They are not only a mandatory requirement to meet industry standards but also a key support for enterprises to reduce costs and achieve intelligent production. Therefore, the application of crack detection devices is irreplaceable.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following shortcomings often exist: Existing brick sintering crack detection devices rely on high-definition cameras to detect defects and cracks on the brick surface. Current detection technologies largely depend on manual visual inspection or single-direction mechanical inspection, resulting in low efficiency, high labor intensity, and poor accuracy in identifying minute cracks. Traditional mechanical inspection equipment requires multiple flipping of the brick to complete multi-faceted inspection, which can easily damage the brick, and the inspection process is cumbersome and time-consuming. Some devices use a fixed camera layout, which cannot adapt to bricks of different sizes, creating blind spots and leading to a high rate of missed detections, further reducing detection accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing earthquake-resistant lightweight brick sintering crack detection device has the disadvantage of low detection efficiency. Therefore, we propose an earthquake-resistant lightweight brick sintering crack detection device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a seismic-resistant lightweight brick sintering crack detection device, comprising a workbench and a robotic arm disposed on one side of the workbench.

[0031] The pressing assembly includes a slider 1 slidably connected inside the groove 81, a rack 83 on one side of the slider 1, a pressure plate 82 at the top of the rack 83, a spring 1 between the slider 1 and the groove 81, a rotating rod 85 rotatably connected inside the groove 81, a gear 84 on the outside of the rotating rod 85, the gear 84 meshing with the rack 83, a bevel gear set including a bevel gear 86 on the outside of the rotating rod 85, a screw 89 rotatably connected to the outside of the rotating rod 85, the screw 89 connected to the groove 81, a bevel gear 88 rotatably connected to the screw 89, a vertical rod 811 at the top of the screw 89, and a sleeve 810 slidably connected to the vertical rod 811, so as to realize the synchronous lifting of the two sets of top plates 812, ensuring that the chemically tempered glass 73 and the bricks are subjected to balanced force, and avoiding brick displacement or glass breakage during the lifting process.

[0032] The moving component 9 includes a slider 2 slidably connected inside the groove 81. A rack 2 92 is provided on one side of the slider 2. A spring 2 is provided between the slider 2 and the groove 81. A driven plate 91 is provided at the top of the rack 2 92. A lead screw 94 is rotatably connected inside the groove 81. A gear 2 93 is provided on the outside of the lead screw 94. The gear 2 93 is meshed with the driven plate 91. The lead screw 94 is threadedly connected to the moving block 95, realizing the connection between the brick exposure and the camera alignment. No step-by-step operation is required, which greatly improves the detection efficiency.

[0033] Working principle: First, the shock-resistant lightweight bricks stacked on the surface of the extension table 10 are placed at the center of the chemically tempered glass 73 using a feeding assembly or robot. The bottom of the chemically tempered glass 73 is attached by four sets of suction cups 72, which are fixed to the surface of the worktable 1 by support columns 71. After the shock-resistant lightweight bricks are placed, the operator starts the robotic arm 2 to move one side of the frame 3 directly above the shock-resistant lightweight bricks. Then, the robotic arm 2 drives the frame 3 downward, causing the frame 3 to move the bottom plates 11 on both sides downward. As a result, the bottom plates 11 press against the corresponding pressure plate 82 below. When the pressure plate 82 moves downwards, the rack 83 at the bottom end moves downwards. A slider is provided on one side of the rack 83, and the rack 83 is slidably connected to a groove 81 on the surface of the worktable 1 via the slider. A spring is provided between the slider and the groove 81. The rack 83 is meshed with a gear 84, which drives the rotating rod 85 to rotate. The rotating rod 85 is rotatably connected to the groove 81, and the rotating rod 85 drives the bevel gear 86 on the surface to rotate. The rotating rod 85 is meshed with a rectangular block 87, which drives the bevel gear 88 to rotate. The bevel gear 88 is rotatably connected to a screw 89, and the screw 89 is rotatably connected to the rotating rod 86. The moving rod 85 is rotatably connected, the bevel gear 88 is threadedly connected to the sleeve 810, the sleeve 810 is slidably connected to the vertical rod 811, and one end of the vertical rod 811 is connected to the screw 89. Thus, the sleeve 810 drives the top plate 812 to push the chemically tempered glass 73 upwards. Since there are two sets of top plates 812 symmetrically distributed about the rotating rod 85, the two sets of top plates 812 simultaneously push the chemically tempered glass 73 upwards. Because shock-resistant lightweight bricks are placed on the top of the chemically tempered glass 73, the two sets of top plates 812 push the shock-resistant lightweight bricks on the top of the chemically tempered glass 73 upwards, causing the chemically tempered glass 73 to detach. The suction cup 72 is fixed to the surface of the workbench 1 by the support column 71 at the bottom. The top plate 812 pushes the chemically tempered glass 73 upward a certain distance, so that the bottom of the shock-resistant lightweight brick can be fully seen by the high-definition camera 96. The two sets of top plates 812 are lifted synchronously to ensure that the chemically tempered glass 73 and the brick are subjected to balanced force, and to avoid the brick shifting or glass breakage during the lifting process. After lifting, the bottom of the brick is completely exposed without any blind spots, providing a complete field of view for bottom surface inspection. At the same time, the spring can realize the automatic reset of the rack 83 without the need for an additional drive mechanism, simplifying the structure and improving the continuity of action.

[0034] The bottom plates 11 on both sides of the synchronous frame 3 also press down on the driven plate 91, which in turn presses down on the rack 2 92. The rack 2 92 drives the slider 2 on one side to slide into the groove 81. A spring 2 is provided between the slider 2 and the groove 81, and the spring 2 is used to reset the rack 2 92. The rack 2 92 meshes with the gear 2 93, which drives the lead screw 94 to rotate. The lead screw 94 rotates into the groove 81 and is threaded into the moving block 95. The moving block 95 slides into the groove 81, and the moving block 95 drives the high-definition camera 2 96 at the top to move towards the center of the chemically tempered glass 73. Since the chemically tempered glass 73 is transparent, from The high-definition camera 2 96 can detect defects and cracks on the bottom surface of the earthquake-resistant lightweight bricks on the top surface of the chemically tempered glass 73 without flipping the bricks. The lifting and movement of the high-definition camera 1 6 are triggered simultaneously by the bottom plate 11, realizing the connection between the exposure of the bricks and the alignment of the camera. This eliminates the need for step-by-step operations and greatly improves the detection efficiency. The chemically tempered glass 73 has the characteristics of high light transmittance, scratch resistance, and high support strength. It not only ensures the clarity of the image on the bottom surface of the bricks, but also stably supports the bricks, avoiding the impact of glass scratches or breakage on the results during the detection process. The spring 2 enables the rack 2 92 to automatically reset, allowing the high-definition camera 2 96 to quickly return to the initial position after detection, which is suitable for continuous detection processes.

[0035] An adjustment structure 4 is provided inside the frame 3, and a lighting lamp 5 is provided at the bottom of the fixed shell 41. Since the sizes of the earthquake-resistant lightweight bricks are inconsistent, the position of the high-definition camera 6 can be flexibly adjusted according to the size of the earthquake-resistant lightweight bricks using the adjustment structure 4. The motor 43 is started and fixedly connected to the fixed shell 41 via a fixed bracket 42. The fixed shell 41 is fixedly connected to the inner side of the frame 3. The motor 43 drives a rotating disk 44 on one side to rotate, which in turn drives the arc-shaped groove 45 on its surface to rotate. This causes the arc-shaped groove 45 to slide in connection with a circular moving block 46. The circular moving block 46 drives an adjustment plate 48 on one side to slide in connection with a cross plate 47. The cross plate 47 is fixedly connected to the fixed shell 41. The adjustment plate 48 drives a vertical connecting plate 410 on one side to adjust its position. A high-definition camera 6 is symmetrically arranged on one side of the vertical connecting plate 410. High-definition cameras 6 are installed on all four sides of the earthquake-resistant lightweight brick, and symmetrical high-definition cameras 6 are also installed at the bottom of the horizontal connecting plate 49 on one side of the fixing frame 42. Thus, multiple sets of high-definition cameras 6 and high-definition cameras 96 can simultaneously detect cracks on all six sides of the earthquake-resistant lightweight brick. The rotating disk 44 is driven by motor 43 and linked with the arc groove 45 to realize the synchronous position adjustment of multiple sets of high-definition cameras 6, which can adapt to the detection needs of bricks of different sizes. No manual disassembly and adjustment are required, reducing the difficulty of operation. The high-definition cameras 6 and 96 work synchronously, and the entire surface of the brick can be covered in one inspection. This avoids the omission of detection and damage to the brick caused by flipping or multiple displacements, which significantly improves the comprehensiveness and accuracy of the inspection. The lighting provides uniform illumination, eliminates shadows on the brick surface, enhances the contrast between cracks and bricks, and further improves the accuracy of crack recognition.

[0036] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
