Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and in particular relates to a highly compatible circular tube inspection device. Background Technology

[0002] Round pipes are typically connected to other pipe fittings, and their dimensional requirements are high. After manufacturing, round pipes need to undergo quality inspection to ensure the reliability of the connection. Specifically, it is necessary to check whether the length, inner diameter, chamfer, and other dimensions of the round pipe meet the specified standards. Manual inspection of round pipes is not only inaccurate but also inefficient.

[0003] In the prior art, Chinese invention patent application publication number CN118904736A discloses an automated visual inspection device, including a feeding device, an inspection device, a conveying device, a screening device, and a controller. In this solution, a vibratory feeder feeds the material, and a receiving mechanism divides the round tube into individual round tubes. The round tubes fall onto the rotating disk from the discharge notch of the receiving wheel, thus realizing the feeding action of the round tubes. This solution has the following problems: (1) The round pipe is in a vertical position on the receiving mechanism. When the round pipe falls from the feeding notch of the receiving wheel onto the rotating disk, due to the inertia of the rotating disk, the bottom of the round pipe will tend to rotate with the rotating disk at the moment of contact with the rotating disk after falling. This will cause the round pipe to tip over at the moment of falling onto the rotating disk, which will affect the subsequent inspection. (2) The receiving notch on the receiving wheel can only be used to fit round pipes with a set diameter. If the size of the round pipe being tested is too large or too small, the receiving mechanism cannot be used and cannot be used to fit other round pipes of different sizes. It has poor flexibility and poor versatility.

[0004] Therefore, it is necessary to provide a highly compatible circular tube inspection device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a highly compatible round tube testing device, which solves the problems of unstable round tube feeding, poor equipment compatibility, and low testing accuracy, and realizes efficient, stable, and high-precision automated testing and sorting of round tubes of various specifications.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a highly compatible circular tube inspection device, comprising a rotating disk, an annular positioning carrier detachably disposed on the edge of the upper surface of the rotating disk and concentric with the rotating disk, and a feeding device, a guiding module, a first inspection camera, a second inspection camera, a third inspection camera, a fourth inspection camera, and a unloading device disposed along the conveying direction of the rotating disk. The annular positioning carrier is provided with a plurality of first receiving slots at equal angles around its circumference. The feeding device includes a vibratory disk that outputs horizontally positioned circular tubes, a conveying track connected to the vibratory disk, a material distribution module disposed at the front end of the material distribution track, and a conveying mechanism that transports the circular tubes on the material distribution module into the first receiving slots.

[0007] Furthermore, the rotating disk has a plurality of light-transmitting holes arranged along its circumference, the light-transmitting holes corresponding to the first receiving groove, and the opening size of the light-transmitting holes corresponding to the size of the circular tube.

[0008] Furthermore, the annular positioning carrier includes several annular components, which are spliced ​​together from the edge of the rotating disk towards the center and are concentrically arranged. The width of the annular positioning carrier can be adjusted by increasing or decreasing the number of the annular components.

[0009] Furthermore, the material distribution module includes a material distribution seat and a material distribution cylinder for driving the material distribution seat to perform lifting and lowering actions. The material distribution cylinder is adjustablely mounted on a first mounting frame. The material distribution seat is provided with a second receiving groove and a limiting block. The material distribution seat is provided with a downwardly extending limiting part at one end away from the limiting block.

[0010] Furthermore, the limiting block is adjustablely positioned on the material distribution seat along the length direction of the second receiving groove.

[0011] Furthermore, a third receiving groove is provided on the material conveying track, and a direct vibration module is provided below the material conveying track.

[0012] Furthermore, a clamping assembly is provided at the end of the conveying track. The clamping assembly includes a clamping block disposed above the conveying track and a clamping element disposed on the clamping block in an adjustable vertical position.

[0013] Furthermore, the conveying mechanism includes a translation drive, a first support plate driven by the translation drive to move horizontally, a lifting drive mounted on the first support plate, and a lifting frame driven by the lifting drive to move vertically. The lifting frame is provided with a plurality of adsorption elements, each of which is individually controlled. The translation drive is adjustable in vertical position on a second mounting frame.

[0014] Furthermore, the guiding module includes a first straightening block for straightening one end of the circular tube, a second straightening block for straightening the vertical position of the circular tube, and a third mounting bracket for mounting the first straightening block and the second straightening block. The positions of the first straightening block and the second straightening block are adjustable.

[0015] Furthermore, the feeding device includes a defective product feeding mechanism, a good product feeding mechanism, and a retesting product feeding mechanism. Each of the defective product feeding mechanism, the good product feeding mechanism, and the retesting product feeding mechanism includes a receiving pipe disposed on the outer periphery of the rotating disk and a pushing assembly disposed above the rotating disk. The pushing assembly includes a pushing plate and a pushing cylinder that drives the pushing plate to move radially along the rotating disk.

[0016] Compared with existing technologies, the advantages of this utility model's highly compatible round tube testing equipment are as follows: This solution effectively solves the problems of unstable round tube feeding, poor equipment compatibility, and low testing accuracy in existing technologies through a series of mechanical structures, adjustable mechanisms, and automated control. It achieves efficient, stable, and high-precision automated testing and sorting of round tubes of various specifications, possessing high practical value and market potential. Specifically: 1. Significantly improves the stability and reliability of the testing process: By setting up a material distribution module and a conveying mechanism, the process of horizontally conveying the round tube to being stably adsorbed and transported to the rotary table is realized. The limiting block and clamping component in the material distribution module effectively prevent the round tube from tipping over, shifting or interfering with each other during the material distribution and feeding process, solving the risk of the round tube easily tipping over and ensuring the positioning accuracy of the subsequent testing station. 2. Excellent equipment compatibility and versatility: The core ring positioning carrier adopts a detachable design and a modular (multiple ring parts spliced) structure. The width of the carrier can be adjusted by adding, removing or replacing ring parts, easily adapting to round tubes of different lengths. At the same time, the first receiving groove, the second receiving groove, etc., adopt a V-shaped or arc-shaped groove design, which can be compatible with round tubes of different diameters within a certain range, realizing the adaptation to round tubes of different sizes. The upper and lower positions of the material distribution module, the front and rear positions of the limit blocks, the upper and lower positions of the conveying mechanism, and the position of the guiding module can all be flexibly adjusted. This allows the equipment to quickly adapt to the inspection needs of round tubes of different specifications, greatly improving the flexibility and versatility of the equipment. 3. Optimize detection accuracy and imaging quality: The rotating disk and the ring positioning carrier are made of transparent materials (such as acrylic) and are equipped with light-transmitting holes corresponding to the round tubes. This allows the inspection camera to illuminate from the bottom, creating a backlighting effect that can more clearly capture the outline and inner diameter of the round tubes, thereby improving the accuracy of dimensional measurement. A dedicated alignment module (first alignment block and second alignment block) aligns the ends and horizontal posture of the round tubes, ensuring that the round tubes are in a uniform and standard position and posture at the inspection station, laying a solid foundation for subsequent high-precision visual inspection. 4. Achieve efficient and automated inspection and sorting process: The entire process, from loading, positioning, alignment, multi-camera inspection (length, inner diameter, chamfer) to unloading and sorting (good products, defective products, and retested products), is fully automated. Multiple inspection cameras work together, and different cameras with different fields of view can be selected for round tubes of different lengths, improving overall inspection efficiency. The unloading device automatically classifies and pushes the round tubes to different flow directions based on the inspection results, realizing intelligent management, reducing manual intervention, and ensuring the accuracy and high efficiency of sorting. 5. Ingenious structural design, convenient maintenance and adjustment: The equipment extensively uses mechanical designs such as threaded fasteners, oblong holes, and handwheel adjustments, making the installation, disassembly, and position adjustment of each component very convenient, reducing the difficulty and time cost of debugging the equipment due to product model changes; the modular design concept (such as the ring positioning carrier and optional detection camera) also makes the maintenance and functional expansion of the equipment easier.

Detailed Implementation

[0018] Please refer to Figures 1-6 This embodiment is a highly compatible round tube inspection device 100, which includes a rotating disk 1, an annular positioning carrier 8 detachably disposed on the edge of the upper surface of the rotating disk 1 and concentric with the rotating disk 1, a feeding device 2, a guiding module 9, a first inspection camera 3, a second inspection camera 4, a third inspection camera 5, a fourth inspection camera 6 and a unloading device 7 arranged along the conveying direction of the rotating disk 1. The annular positioning carrier 8 is provided with a plurality of first receiving slots 81 for positioning round tubes 200 at equal angles around its circumference. The feeding device 2 includes a vibratory disk 21 for outputting horizontal round tubes 200, a conveying track 22 connected to the vibratory disk 21, a material distribution module 23 disposed at the front end of the material distribution module 22 and a conveying mechanism 24 for transporting the round tubes 200 on the material distribution module 23 into the first receiving slots 81 of the annular positioning carrier 8.

[0019] A dividing plate 12 is provided below the rotating disk 1. The dividing plate and the rotating disk 1 are connected by several mounting posts 13. The bottom of the dividing plate is driven by a motor 14 to rotate in a dividing manner.

[0020] Both the annular positioning carrier 8 and the rotating disk 1 are made of transparent materials, such as acrylic or other materials, to maximize light transmission and facilitate visual inspection. Simultaneously, the rotating disk 1 has several light-transmitting holes 11 arranged along its circumference. These holes 11 correspond to the first receiving groove 81, and their opening sizes correspond to the dimensions of the circular tube 200. When the circular tube 200 is positioned within the first receiving groove 81, the light source of the detection camera can illuminate the circular tube 200 through the light-transmitting holes 11, thus facilitating camera detection and identification. The first receiving groove 81 positions the outer wall of the circular tube 200, ensuring the circular tube 200 is stably positioned within it.

[0021] In this embodiment, a circular tube 200 is being tested. The first receiving groove 81 is a V-shaped groove or an arc-shaped groove, which can adapt to circular tubes 200 of different diameters, improving flexibility and the versatility of the testing equipment. If other shapes of tubes are being tested, the structure of the first receiving groove 81 can be adjusted accordingly. For example, if a square tube is being tested, the first receiving groove 81 can be set as a square groove. Therefore, the structure of the first receiving groove 81 can be adjusted according to the structure of the actual tube to be tested, and no limitation is imposed here.

[0022] The annular positioning carrier 8 is detachably mounted on the rotating disk 1. Specifically, both the annular positioning carrier 8 and the rotating disk 1 are provided with a plurality of first mounting holes 82, which are located between first receiving grooves 81. First fasteners are tightened into the first mounting holes 82 to enable the installation of the annular positioning carrier 8 and the rotating disk 1. The width of the annular positioning carrier 8 is adjustable. If a circular tube of different length is replaced, an annular positioning carrier 8 of different widths can be replaced accordingly. Simply loosen the first fasteners and replace with another annular positioning carrier 8 of the corresponding width. In this embodiment, the annular positioning carrier 8 includes a plurality of annular components 84, which are spliced ​​from the edge of the rotating disk 1 towards the center, and are concentrically arranged. Each annular component 84 has a first receiving groove 81 at an equal angle. The width of the annular positioning carrier 8 can be adjusted by increasing or decreasing the number of annular components 84. For example, the annular positioning carrier 8 includes multiple annular components 84. If the length of the round tube 200 increases, in order to ensure the stability of the positioning of the round tube 200, one or more annular components 84 can be added to the edge or inner side of the rotating disk 1 to widen the width of the annular positioning carrier 8 so as to position a longer round tube 200. If the length of the round tube 200 decreases, in order to ensure the accuracy of the detection of the round tube 200, both ends of the round tube 200 are exposed in the annular positioning carrier 8, and one or more annular components 84 can be reduced to narrow the width of the annular positioning carrier 8 so as to position a shorter round tube 200.

[0023] The material distribution module 23 includes a material distribution seat 231 and a material distribution cylinder 232 that drives the material distribution seat 231 to perform lifting and lowering actions. The material distribution cylinder 232 is adjustablely mounted on the first mounting frame 233 to facilitate the adjustment of the vertical position of the material distribution seat 231. The material distribution seat 231 is provided with a second receiving groove 2311 for positioning the circular tube 200 and a limiting block 2312 for limiting the front end of the circular tube 200. At the end of the material distribution seat 231 away from the limiting block 2312, a downwardly extending limiting part 2313 is provided. The limiting part 2313 limits the front end of the circular tube 200 on the material conveying track 22 to prevent the second circular tube 200 from falling or shifting its position.

[0024] The limiting block 2312 is adjustablely positioned on the distributing seat 231 along the length of the second receiving groove 2311 to accommodate round tubes 200 of different lengths. Specifically, the limiting block 2312 is detachably mounted on the distributing seat 231 via a second fastener. The limiting block 2312 is provided with an oblong hole 2314. The distributing seat 231 is provided with a plurality of second mounting holes 2315 above the second receiving groove 2311 along its length. The second fastener is inserted into the second mounting holes 2315 at different positions to adjust the position of the limiting block 2312, thereby accommodating round tubes 200 of different lengths.

[0025] The first mounting bracket 233 includes a second support plate 2331 for mounting the dispensing cylinder 232, a third support plate 2332 disposed below the second support plate 2331, and a support column 2333 connecting the second support plate 2331 and the third support plate 2332. The second support plate 2331 and the third support plate 2332 can be adjusted vertically along the support column 2333, thereby adjusting the vertical position of the dispensing seat 231. After the vertical position adjustment of the second support plate 2331 and the third support plate 2332 is completed, the second support plate 2331 and the third support plate 2332 are... The third support plates 2332 are all tightened by the third fasteners 2334. An adjusting member 2335 is provided on the third support plate 2332. The upper end of the adjusting member 2335 abuts against the lower surface of the second support plate 2331. When it is necessary to adjust the vertical position of the material distribution seat 231, loosen the third fasteners 2334, then turn the adjusting member 2335 up or down to adjust the second support plate 2331 to the set position. Then tighten the third fasteners 2334 to fix the position of the second support plate 2331, thus achieving the position adjustment of the material distribution seat 231. When adjusting the vertical position of the second support plate 2331, the vertical position of the third support plate 2332 can also be adjusted simultaneously by loosening the third fasteners 2334. This allows for simultaneous adjustment of the positions of the second and third support plates 2331 to adjust the position of the material distribution seat 231.

[0026] A third receiving groove 221 for positioning round tubes 200 is provided on the conveying track 22. A direct vibration module 25 is provided below the conveying track 22 to allow the round tubes 200 in the third receiving groove 221 to continue to be conveyed forward. After the first round tube 200 at the front end of the conveying track 22 is completely inserted into the second receiving groove 2311 of the distributing seat 231, the front end of the round tube 200 is restricted on the limiting block 2312. Then, the distributing cylinder 232 drives the distributing seat 231 to rise to the set position and above the conveying track 22. The limiting part 2313 limits the front end of the second round tube 200 on the conveying track 22. Since the round tubes 200 are conveyed end to end on the conveying track 22, When the distributing cylinder 232 drives the distributing seat 231 to rise, in order to prevent the distributing seat 231 from lifting the front end of the second round tube 200 on the conveying track 22 and causing positional displacement, a clamping assembly 222 is provided at the end of the conveying track 22. The clamping assembly 222 includes a clamping block 2221 disposed above the conveying track 22 and a clamping member 2222 disposed on the clamping block 2221 with adjustable vertical position. The clamping member 2222 clamps the end of the round tube 200. In this embodiment, the clamping member 2222 is a bolt. The height from the bottom of the bolt to the bottom of the third receiving groove 221 is slightly greater than the diameter of the round tube 200. This ensures that the first round tube 200 at the front end of the conveying device smoothly enters the distributing seat 231 from the bottom of the clamping member 2222, and also clamps the front end of the second round tube 200 on the conveying track 22, preventing the front end of the second round tube 200 from tilting up and causing positional displacement.

[0027] The structures of the second receiving groove 2311 and the third receiving groove 221 are consistent with the structure of the first receiving groove 81, and will not be described again here.

[0028] The conveying mechanism 24 includes a translation drive 241, a first support plate 242 driven by the translation drive 241 to move horizontally, a lifting drive 243 mounted on the first support plate 242, and a lifting frame 246 driven by the lifting drive 242 to move vertically. The lifting frame 246 is equipped with several suction elements 244, each of which is individually controlled. In actual use, one or more suction elements 244 can be selected to accommodate circular tubes 200 of different lengths. The translation drive 241 is adjustable in height on a second mounting bracket 245 to accommodate circular tubes 200 of different diameters. The second mounting bracket 245 includes a handwheel 2451 and a lead screw 2452 connected to the handwheel 2451. The translation drive component 241 is fixed on the support frame 2453, and the support frame 2453 is connected to the lead screw 2452. By rotating the handwheel 2451, the up and down position of the support frame 2453 can be adjusted, thereby adjusting the up and down position of the adsorption component 244 so as to be able to adapt to round tubes 200 of different diameters.

[0029] The alignment module 9 includes a first alignment block 91 for aligning one end of the circular tube 200, a second alignment block 92 for aligning the vertical position of the circular tube 200, and a third mounting bracket 93 for mounting the first alignment block 91 and the second alignment block 92. The first alignment block 91 aligns the end of the circular tube 200 to make the front and rear ends of the circular tube 200 consistent, which is convenient for subsequent camera photography and inspection. The second alignment block 92 aligns the horizontal circular tube 200 to prevent one end of the circular tube 200 from tilting up, which would affect the accuracy of subsequent inspection.

[0030] The third mounting bracket 93 includes a support rod 931, a first mounting block 932 and a second mounting block 933 movably mounted on the second support plate 931. The first alignment block 91 is fixed to the first mounting block 932 via a connecting rod 935, and the second alignment block 923 is fixed to the second mounting block 933. Both the first mounting block 932 and the second mounting block 933 can rotate around the second support plate 931 and move up and down along the second support plate 931 to adjust the distance and vertical position of the first alignment block 91 and the second alignment block 923 from the rotating disk 1. Specifically, the first mounting block 932 and the second mounting block 933 are adjustablely mounted on the support rod 931 via a fourth fastener. If the position of the first mounting block 932 and the second mounting block 933 needs to be adjusted, simply loosen the fourth fastener, adjust the position, and then tighten the fourth fastener.

[0031] The first fastener, the second fastener, the third fastener, and the fourth fastener are selected from one of the bolts, screws, or pins, or fasteners of other structures, without limitation.

[0032] Both the first detection camera 3 and the third detection camera 5 are used to detect the length of the circular tube 200. The first detection camera 3 has a small field of view and is suitable for detecting short circular tubes 200, while the third detection camera 5 has a large field of view and is suitable for detecting longer circular tubes 200. In actual use, the first detection camera 3 and the third detection camera 5 are used selectively. The first detection camera 3 is used for short circular tubes 200, and the third detection camera 5 is used for long circular tubes 200.

[0033] The two ends of the circular tube 200 are end A and end B, and both ends A and B have chamfers inside. The second detection camera 4 is set on the outer periphery of the rotating disk 1 to detect the inner diameter of end A of the circular tube 200. The fourth detection camera 6 detects the inner diameter of end B of the circular tube 200. The fourth detection camera 6 is set at the center of the rotating disk 1 through a camera bracket 61 so as to detect the inner diameter of end B of the circular tube 200.

[0034] The feeding device 7 includes a defective product feeding mechanism 71, a good product feeding mechanism 72, and a retesting product feeding mechanism 73. If the test result is unqualified, the product is pushed to the defective product feeding mechanism 71. If the test result is qualified, the product is pushed to the good product feeding mechanism 72. If the test result cannot be determined, the product is pushed to the retesting product feeding mechanism 73 for further testing and confirmation.

[0035] The defective product unloading mechanism 71, the good product unloading mechanism 72, and the retesting product unloading mechanism 73 have the same or similar structures, and all include a receiving pipe 721 disposed on the outer periphery of the rotating disk 1 and a pushing assembly 722 disposed above the rotating disk 1. The pushing assembly 722 includes a pushing plate 7221 and a pushing cylinder 7222 that drives the pushing plate 7221 to move radially along the rotating disk 1.

[0036] When using the highly compatible circular tube testing device 100 provided by this solution, the vibratory feeder 21 outputs a horizontally positioned circular tube 200. The first circular tube 200 at the front end of the conveyor is completely inserted into the second receiving groove 2311 of the distribution seat 231 via the conveying track 22. At this time, the front end of the circular tube 200 is restricted on the limiting block 2312. Then, the distribution cylinder 232 drives the distribution seat 231 to rise to the set position and above the conveying track 22. The limiting part 2313 limits the front end of the second circular tube 200 on the conveying track 22. The conveying mechanism 24 moves above the distribution module 23. The translation drive 241 and the lifting drive 243 jointly drive the adsorption member 244 to adsorb the outer wall of the circular tube 200 and transport the circular tube 200 to the annular positioning carrier. In the first receiving slot 81 of the 8, the rotating disk 1 rotates and transports the round tube 200 to the guiding module 9. The first straightening block 91 straightens the end of the round tube 200, and the second straightening block 92 straightens the horizontal round tube 200. After straightening, the rotating disk 1 rotates and transports the round tube 200 to several subsequent inspection cameras to inspect the length, chamfer, inner diameter and other dimensions of the round tube 200. After inspection, the rotating disk 1 rotates and transports the round tube 200 to the unloading device 7. If the inspection result is unqualified, it is pushed to the defective unloading mechanism 71. If the inspection result is qualified, it is pushed to the good unloading mechanism 72. If the inspection result cannot be judged, it is pushed to the retest unloading mechanism 73 for further inspection and confirmation.

[0037] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
