Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically a rotating visual inspection platform. Background Technology

[0002] Visual inspection technology is an advanced technology based on computer vision and image processing. It uses machine vision devices, such as industrial cameras, to convert the captured target into image signals, which are then analyzed and processed by a dedicated image processing system to achieve the detection, measurement, and judgment of workpieces. Workpiece appearance defect detection is one of the most widely used applications of visual inspection technology. Specific detection contents include scratches, dents, dirt, etc. on the overall appearance of the workpiece. Visual inspection platforms are often used when workers perform defect detection on tubular workpieces. Visual inspection can provide comprehensive and objective quality assessment, which meets the needs of intelligent manufacturing and globalized production.

[0003] When using existing rotary vision inspection platforms, workers first use clamping components to position and fix the pipes on top of the platform. Then, they use machine vision devices to inspect the pipes from the outside. During this process, the position of the machine vision devices often needs to be adjusted to achieve a comprehensive inspection of the overall appearance of the pipes. However, the continuous back-and-forth movement of the machine vision devices can lead to instability in the pipe inspection values, which affects the accuracy of the inspection values ​​and hinders the normal operation of vision inspection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7As shown, a rotary visual inspection platform includes a base plate 1, a top plate 2 above the base plate 1, a receiving cavity 5 inside the top plate 2, a support cylinder 6 inside the receiving cavity 5, the top of the support cylinder 6 extending through to the outside of the receiving cavity 5 and fixedly connected to an inspection table 7; a placement groove 8, located on top of the inspection table 7, containing a pipe body 9, with a support plate 10 at the top of the inner cavity of the pipe body 9, and two symmetrically arranged moving blocks 11 below the support plate 10; an inner support assembly 12, located outside the moving blocks 11, for positioning and fixing the pipe body 9 from inside; by setting the inner support assembly 12, stable positioning and fixing of the pipe body 9 can be achieved without obstructing its appearance, thereby reducing the probability of the pipe body 9 shifting or tilting during inspection and improving the inspection stability of the pipe body 9; a rotating assembly 16 is located outside the receiving cavity 5 for adjusting the inspection position of the pipe body 9; by setting the rotating assembly 16, the inspection table 7 and the pipe body 9 on top can be rotated as a whole. The rotating mechanism allows for quick adjustment of the inspection position of the pipe body 9 by staff, facilitating comprehensive defect detection of the pipe body 9's appearance. Two side support plates 3 are symmetrically installed on the top of the base plate 1. Lifting components 4 for adjusting the height of the pipe body 9 are located on the outer side of the side support plates 3. These lifting components 4 allow for vertical vertical displacement of the inspection platform 7 and the pipe body 9 on top. Combined with the rotating component 16, this enables the detection of defects at any location on the outer surface of the pipe body 9, preventing any omissions in the detection of defects. A camera component 20 for detecting defects in the appearance of the pipe body 9 is located on one side of the inspection platform 7. This camera component 20 captures optical images of the surface of the pipe body 9 and uses image processing algorithms to identify defects such as cracks, corrosion, and deformation. This allows staff to intuitively understand the appearance of the pipe body 9, helping them eliminate substandard pipe bodies 9 and improve the overall quality of the pipe body 9.

[0018] The inner support assembly 12 includes an extension 121 disposed on the outside of the movable block 11. Multiple extensions 121 are provided. The movable block 11 and the support plate 10 are on the same plane. Multiple L-shaped inner support plates 125 are symmetrically arranged inside the pipe body 9, located above the testing table 7. A first U-shaped seat 122 is fixedly installed at one end of the extension 121. A second U-shaped seat 123 is fixedly installed on one side of the L-shaped inner support plate 125. A connecting rod 124 is provided between the first U-shaped seat 122 and the second U-shaped seat 123. The connecting rod 124 is rotatably connected to the first U-shaped seat 122 and the second U-shaped seat 123 via a rotating shaft. The other side of the L-shaped inner support plate 125 contacts the inner wall of the pipe body 9. A friction pad 126 is fixedly connected to the outside of the L-shaped inner support plate 125. The friction pad 126 is made of rubber or silicone material. Figure 3 , Figure 4 and Figure 7 As shown, before performing defect detection on the pipe body 9, the pipe body 9 to be tested can be placed in the placement slot 8 on the top of the testing table 7. Then, the two moving blocks 11 are driven to move closer to each other. With the cooperation of the first U-shaped seat 122 at one end of the extension 121 and the second U-shaped seat 123 on one side of the L-shaped inner support plate 125, multiple L-shaped inner support plates 125 can expand outward synchronously until they contact the inner wall of the pipe body 9. This can reduce the probability of the pipe body 9 shifting or tilting during the testing process. The L-shaped inner support plate 125 can achieve stable positioning and fixation of the pipe body 9 without obstructing its appearance. The friction pad 126 will increase the friction between the L-shaped inner support plate 125 and the pipe body 9, which can effectively prevent the pipe body 9 from slipping during the testing process.

[0019] A first motor 13 is fixedly installed at the bottom of the testing table 7. The output end of the first motor 13 extends through to the outside of the testing table 7 and is fixedly connected to a bidirectional ball screw 14. The top end of the bidirectional ball screw 14 is rotatably connected to the support plate 10. Multiple guide posts 15 are symmetrically arranged around the bidirectional ball screw 14. The guide posts 15 are respectively connected to the support plate 10 and the testing table 7. The moving block 11 is screwed to the bidirectional ball screw 14 through a nut. One end of the extension 121 is slidably connected to the guide post 15. The top of the testing table 7 has a guide groove 17 corresponding to the L-shaped inner support plate 125. The bottom of the L-shaped inner support plate 125 is slidably connected to the guide groove 17. Figure 3 , Figure 4 and Figure 7 As shown, the first motor 13 can drive the bidirectional ball screw 14 to rotate, and the bidirectional ball screw 14 can then drive the two moving blocks 11 to move closer or further away from each other along their axial direction. Through the transmission cooperation between the first U-shaped seat 122, the second U-shaped seat 123 and the connecting rod 124, the L-shaped inner support plate 125 can be driven to move closer or further away from the pipe body 9. In this way, the L-shaped inner support plate 125 can be driven to position and fix the pipe body 9, or to release the L-shaped inner support plate 125 from the positioning and fixing of the pipe body 9.

[0020] A through groove 21 is provided at the bottom of the inner cavity of the receiving cavity 5. A drive shaft 22 is coaxially arranged inside the through groove 21.

The conductive slip ring 23 is fixedly installed at the bottom of the receiving cavity 5, and the rotor of the conductive slip ring 23 is connected to the drive shaft 22. Figure 4 , Figure 6 and Figure 7As shown, it should be noted that the conductive slip ring 23 is an electrical component used in rotating equipment to achieve continuous transmission of power and signals. It is also known as a collector ring, bus ring, or rotary joint. Its core structure consists of a rotor and a stator. A conductive path is formed through elastic contact or rolling overlap to solve the problem of wires tangling during rotation. In actual use, the external power supply is connected to the stator terminal of the conductive slip ring 23 through a data line. Then, the rotor terminal of the conductive slip ring 23 is connected to the terminal of the first motor 13 through a data line. When the first motor 13 rotates as a whole, the data line around the drive shaft 22 also rotates with the first motor 13, thereby achieving stable power supply and control for the first motor 13.

[0021] The rotating assembly 16 includes an annular seat 163 disposed around the periphery of the receiving cavity 5. The top of the annular seat 163 is connected to the detection platform 7.

The output end of the second motor 161 extends through to the outside of the top plate 2 and is fixedly connected to a gear 162. One side of the gear 162 meshes with the gear ring 164. The detection platform 7 has intermittently spaced heat dissipation grooves 165 inside. The support cylinder 6 is connected to the outside through the heat dissipation grooves 165. Figure 2 , Figure 4 and Figure 5 As shown, the second motor 161 can drive the gear 162 to rotate, and then the gear 162 can drive the ring seat 163 and the inspection table 7 to rotate through the gear ring 164. This makes it easy for the staff to quickly adjust the inspection position of the pipe body 9 according to the actual situation, which is conducive to realizing all-round defect inspection of the appearance of the pipe body 9. In addition, by setting the heat dissipation groove 165, the working heat of the second motor 161 inside the support cylinder 6 can be easily dissipated to the external environment, thereby avoiding the overheating of the second motor 161 caused by heat accumulation.

[0022] A slider 18 is fixedly connected to the bottom of the testing platform 7, and a groove 19 corresponding to the slider 18 is opened on the top of the receiving cavity 5. The slider 18 is located inside the groove 19, such as... Figure 5 As shown, by setting the slide groove 19 and the slider 18, the entire detection stage 7 can rotate smoothly, which helps to improve the working stability of the rotating component 16.

[0023] The lifting assembly 4 includes a lifting cylinder 41 fixed to one side of the side support plate 3. The top end of the lifting cylinder 41 passes through the side support plate 3 and connects to the top plate 2. Sliding rods 42 are vertically installed at each of the four bottom corners of the top plate 2, and the bottom ends of the sliding rods 42 extend through to the outside of the side support plate 3. Figure 1 , Figure 2 and Figure 3As shown, the lifting cylinder 41 can drive the inspection platform 7 and the pipe body 9 on top of it to move vertically up and down. In conjunction with the rotating component 16, it can realize the detection of defects at any position on the outer surface of the pipe body 9, thereby avoiding the omission of the detection position of the appearance defects of the pipe body 9. Compared with the common inspection platform that requires the displacement adjustment of the position of the machine vision device during the inspection process, this utility model can ensure that the camera component 20 can complete the all-round defect detection of the pipe body 9 while remaining stable.

[0024] The camera assembly 20 includes a vertical rod 201 disposed on one side of the inspection table 7. The bottom end of the vertical rod 201 is connected to the base plate 1, and a horizontal rod 202 is fixedly connected to the top end of the vertical rod 201. A support base 203 is fixedly connected to the end of the horizontal rod 202 near the tube body 9. A CCD camera 204 is fixedly installed inside the support base 203. Figure 2 , Figure 3 and Figure 4 As shown, the CCD camera 204 can capture optical images of the surface of the pipe body 9, and the image processing algorithm can be used to identify defects such as cracks, corrosion, and deformation. This allows the staff to intuitively understand the appearance of the pipe body 9, which helps to eliminate substandard pipe bodies 9 and improve the product quality of the pipe body 9. It should be noted that the CCD camera 204 is a line scan camera in the prior art. It images the object through a row of pixel arrays and constructs the image pixel by pixel. It is suitable for shooting high-speed motion or detecting continuous motion.

[0025] Working principle: First, the operator places the pipe body 9 to be inspected on the placement slot 8 at the top of the inspection table 7. Then, the inner support component 12 reduces the probability of the pipe body 9 shifting or tilting during the inspection process. The L-shaped inner support plate 125 achieves stable positioning and fixation of the pipe body 9 without obstructing its appearance. During the appearance defect inspection of the camera component 20, the rotation component 16 and the lifting component 4 can be used to locate and detect defects at any position on the outer surface of the pipe body 9, thereby avoiding the omission of appearance defect detection positions of the pipe body 9. Compared with common inspection platforms that require displacement adjustment of the machine vision device during the inspection process, this utility model can ensure that the camera component 20 can complete the all-round defect inspection of the pipe body 9 while remaining stable.
