Abstract

This invention relates to the field of pipe fitting inspection technology, specifically an AI detection device and method for detecting the eccentricity of cut holes in towel rack pipe fittings. The device includes a base and a stand fixed to the base, and further includes: a laser scanner mounted on the stand, capable of moving along the height of the stand; a clamping platform mounted on the base and located on the side of the stand facing the laser scanner; and a vertical cylinder rotatably mounted in the clamping platform, connected to two opposing limiting blocks.

Description

Technical Field

[0001] This invention relates to the technical field of pipe fitting inspection, specifically to an AI detection device and method for detecting the eccentricity of cut holes in towel rack pipe fittings. Background Technology

[0002] Towel racks are common bathroom fixtures, primarily used for hanging towels. They are typically constructed from multiple tubing components connected by interlocking mechanisms to form a unified structure. During the manufacturing process, axially spaced, regularly arranged holes are cut into the surfaces of the pre-cut tubing. These holes are used for interlocking with other tubing components to assemble the towel rack. To ensure the final towel rack meets specifications, these holes undergo eccentricity testing.

[0003] Currently, the eccentricity detection of pipe fitting holes typically involves transporting the pipe fitting to a clamping table, where clamps hold and fix the bottom end of the fitting. Laser scanning combined with AI analysis is then used to determine if the eccentricity of the hole meets requirements. However, if the clamping operation is performed manually, inaccurate operation may cause the fitting to deviate, resulting in a misalignment between the fitting and the laser scanning path, leading to erroneous detection results.

[0004] In some automated production processes, although robotic arms are used to transfer the pipe to be tested from the conveyor belt to the clamping table for gripping, if the robotic arm releases the pipe first, and then the clamping table clamps it again (i.e., multiple clamping pieces move closer together), the pipe can easily become skewed, which directly affects the accuracy of subsequent laser scanning. Furthermore, if the robotic arm maintains its grip on the pipe during clamping, and the clamping table also applies force, the clamping table will exert additional clamping force. If the clamping forces of the robotic arm and the clamping table are not aligned, or if there is a deviation in the clamping position, the pipe will be subjected to forces from different directions, potentially causing damage, especially to thin-walled or softer pipes, which are more prone to deformation. Due to uneven clamping forces or conflicting clamping positions, the pipe may not be accurately positioned on the clamping table, and its axis may deviate from the intended position, resulting in pipe skew. This will cause the scanning path to mismatch with the actual position of the cut hole during subsequent laser scanning, making it impossible to accurately obtain the complete outline and size information of the cut hole, ultimately resulting in a large error in the detection results and seriously affecting the accuracy of the detection. Summary of the Invention

[0005] The purpose of this invention is to provide an AI detection device and method for detecting the eccentricity of the cut holes in towel rack tube fittings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An AI detection device for the eccentricity of a towel rack tube fitting cut hole includes a base and a stand fixed on the base, and further includes: A laser scanner mounted on a stand, capable of moving along the height of the stand; A clamping platform is mounted on the base and located on the side of the stand facing the laser scanner; Rotate the vertical cylinder installed in the clamping table.

The support structure is located at the top of the vertical cylinder to support the bottom end of the pipe fitting, and the center of the turntable is provided with a guide port for the bottom end of the pipe fitting to enter the clamping table.

[0007] As a further aspect of the present invention: the power mechanism includes two second cylinders fixed in the clamping table and a follower frame fixedly connected to the movable ends of the two second cylinders, the follower frame being rotatably connected to a kit slidably sleeved on the vertical cylinder; The kit is connected to a radially movable structure disposed on the vertical cylinder, and the radially movable structure is connected to the limiting block through an elastic component.

[0008] As a further embodiment of the present invention: the radially movable structure includes a support arm fixed to the vertical cylinder, a slider slidably disposed on the support arm, a support rod disposed between the slider and the vertical cylinder, and the two ends of the support rod being hinged to the slider and the kit respectively.

[0009] As a further embodiment of the present invention: a vertical arm is fixed on the slider, and the elastic component includes two guide posts slidably disposed on the vertical arm, a connecting block fixedly connecting the two guide posts, and a second spring sleeved on the outer periphery of the guide posts. The second spring is connected to the vertical arm and the connecting block at both ends, and the limiting block is rotatably mounted on the side of the connecting block away from the vertical arm.

[0010] As a further embodiment of the present invention: the turntable is provided with a through groove along the radial direction, the transmission mechanism includes a driven block that is slidably fitted in the through groove, the clamping member is fixedly connected to the driven block, and a sliding fit structure is provided between the driven block and the kit.

[0011] As a further embodiment of the present invention: the sliding fit structure includes a driven plate fixed to the bottom of the driven block and a drive arm fixed to the kit. A drive column is fixedly provided on the drive arm, and a groove adapted to the drive column is provided on the driven plate. The drive column is located in the groove and is slidably connected to the driven plate. The groove includes a vertical groove and an inclined groove connected together.

[0012] As a further embodiment of the present invention: the supporting structure includes a telescopic shaft that slides and fits with the vertical cylinder, and the vertical cylinder is also provided with a first spring, one end of the first spring being connected to the inner wall of the vertical cylinder, the other end being connected to the first end of the telescopic shaft, and a supporting member being fixed to the tail end of the telescopic shaft; The telescopic shaft has two strip-shaped protrusions on its outer wall, and the vertical cylinder has two strip-shaped grooves on its inner wall that are adapted to the strip-shaped protrusions.

[0013] As a further embodiment of the present invention: the adjustment mechanism includes a motor installed on the side of the clamping table, the output shaft of the motor extending into the interior of the clamping table and connected to the vertical cylinder through a bevel gear set.

[0014] As a further embodiment of the present invention: a first guide groove is provided on the base along its own length direction, a transverse sliding seat is slidably provided on the first guide groove, a second guide groove is provided on the transverse sliding seat along the width direction of the base, and the clamping table is slidably provided on the second guide groove; The transverse sliding seat can be driven by a threaded drive mechanism provided on the base to move along the first guide groove. A first cylinder is also fixed on the transverse sliding seat, and the movable end of the first cylinder is fixed to the clamping table.

[0015] An AI method for detecting the eccentricity of cut holes in towel rack tubing, using the aforementioned detection device, includes the following steps: Step 1: The robotic arm places the pipe to be tested into the guide port on the turntable, and the supporting structure supports the bottom end of the pipe. Step two: The power mechanism operates, driving the two limiting blocks closer to the pipe fitting to limit the pipe fitting and center it. Step 3: The transmission mechanism is triggered, causing the two clamping parts to act on the pipe, so that the pipe is corrected from an inclined state to a vertical state. Step 4: The laser scanner scans the pipe fitting, determines the deviation angle of the detection surface of the pipe fitting, and the adjustment mechanism drives the clamping part and the limiting block to rotate the pipe fitting until the detection surface of the pipe fitting is directly facing the laser scanner. Step 5: The laser scanner moves along the height of the stand to scan the holes on the pipe fitting one by one. Through AI analysis, it is determined whether the eccentricity of the holes on the pipe fitting is qualified.

[0016] Compared with the prior art, the beneficial effects of the present invention are: During inspection, the robotic arm places the pipe to be tested into the guide port on the turntable. By setting up sequentially moving limit blocks and clamping components, the pipe is gradually corrected and fixed. This effectively avoids the problem that the pipe is subjected to the force of the clamping components at the bottom while being clamped by the robotic arm. This could lead to damage to the pipe due to inconsistent clamping force directions or deviations in clamping position. At the same time, it avoids the problem that the pipe cannot be accurately positioned on the clamping table due to uneven clamping force or conflicting clamping positions, and its axis may deviate from the predetermined position. This ensures that the scanning path matches the actual position of the cut hole during subsequent laser scanning, obtaining accurate cut hole contour and size information, reducing inspection errors and improving inspection accuracy.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figures 1-10 In this embodiment of the invention, an AI detection device for the eccentricity of a towel rack tube fitting hole includes a base 1 and a stand 2 fixed on the base 1, and further includes: A laser scanner 3 is mounted on the frame 2 and can move along the height direction of the frame 2. A clamping platform 4 is mounted on the base 1 and located on the side of the stand 2 facing the laser scanner 3; Rotate the vertical cylinder 9 installed in the clamping table 4. The vertical cylinder 9 is connected to two oppositely arranged limit blocks 18. The vertical cylinder 9 is provided with a power mechanism for driving the two limit blocks 18 to move synchronously toward the pipe fitting. Rotary disk 27 is mounted on the top of clamping table 4. Two arc-shaped clamping members 25 are movably mounted on the disk 27. The power mechanism is connected to the clamping members 25 through the transmission mechanism. The two clamping members 25 and the two limiting blocks 18 are distributed equidistantly along the circumference. The clamping table 4 is also provided with an adjustment mechanism for driving the clamping members 25 and the limiting blocks 18 to make synchronous circular motion. The support structure is located at the top of the vertical cylinder 9 to support the bottom end of the pipe fitting, and the center of the turntable 27 is provided with a guide port for the bottom end of the pipe fitting to enter the clamping table 4.

[0031] It should be noted that during the inspection, the pipe is clamped and limited by the two clamping members 25 and the two limiting blocks 18, and is kept in a vertical state on the clamping table 4. The laser scanner 3 is facing the pipe and moves up and down on the stand 2, thereby scanning the holes on the pipe with a laser to detect whether the eccentricity of these holes is within the required range. Specifically, during the inspection, the robotic arm clamps the pipe on the conveyor belt, and then inserts one end of the pipe into the guide port. The bottom end of the pipe is supported by the support structure. Then, the robotic arm can release the pipe, and the bottom part of the pipe extends into the clamping table 4. Subsequently, the power mechanism operates, driving the two limiting blocks 18 to move closer to each other, that is, both limiting blocks 18 move towards the pipe, limiting the two sides of the pipe so that the pipe can be centered. However, at this time, the pipe is still tilted in the length direction of the base 1. After the movement process of the limiting blocks 18 is completed, the transmission mechanism is triggered, driving the two clamping members 25 to move towards the pipe on the turntable 27 and act on the pipe. Then, the pipe is gradually corrected from the tilted state to the vertical state. Subsequently, the laser scanner 3 begins to move and scan the pipe. Specifically, the working process of the laser scanner 3 is divided into two stages: In the first stage, the position of the pipe is determined by laser scanning. If the cut hole on the pipe is not directly facing the laser scanner 3, the adjustment mechanism will work to drive the clamping member 25 and the limiting block 18 to make synchronous circular motion. Correspondingly, the pipe can be deflected until the cut hole on it is directly facing the laser scanner 3, so that the scanning and detection work can be carried out smoothly. In the second stage, the laser scanner 3 moves along the height direction of the stand 2 to scan the holes on the pipe one by one, and sends the scanning results to the computer. After AI analysis, it is determined whether the eccentricity of the holes on the pipe is qualified.

[0032] Furthermore, a stand 2 is set up as the moving platform of the laser scanner 3. The laser scanner 3 moves along the height direction of the stand 2 to scan and inspect the pipes that are in a vertical position on the clamping table 4. During testing, the robotic arm places the pipe to be tested into the through-hole on the turntable 27, and the supporting structure supports the bottom end of the pipe, so that the pipe can be temporarily placed. Then the robotic arm can release the clamping state of the pipe. Subsequently, two limiting blocks 18 first act on the pipe to limit the pipe and center it. Then, two arc-shaped clamping members 25 act on the pipe to switch the pipe from an inclined state to a vertical state. Therefore, during the process of transferring the pipe fitting to the clamping table 4, it can be temporarily placed first, and then gradually corrected and fixed by setting the sequentially moving limit block 18 and clamping member 25. This effectively avoids the problem that the pipe fitting is subjected to the force of the clamping member 25 at the bottom while being clamped by the robot arm, which may cause damage to the pipe fitting due to inconsistent clamping force direction or deviation of clamping position. At the same time, it avoids the problem that the pipe fitting cannot be accurately positioned on the clamping table 4 due to uneven clamping force or conflicting clamping positions, and its axis may deviate from the predetermined position. This ensures that when the laser scanner scans later, the scanning path matches the actual position of the cut hole, obtains accurate cut hole contour and size information, reduces detection error, and improves detection accuracy.

[0033] Please refer to it again. Figure 6 , Figure 8 , Figure 9 as well as Figure 10 The power mechanism includes two second cylinders 20 fixed within the clamping platform 4 and a follower frame 21 fixedly connected to the movable ends of the two second cylinders 20. The follower frame 21 is rotatably connected to a kit 19 slidably sleeved on the vertical cylinder 9. The kit 19 is connected to a radially movable structure disposed on the vertical cylinder 9. The radially movable structure is connected to the limiting block 18 via an elastic component. The radially movable structure includes a support arm 12 fixed to the vertical cylinder 9. A slider 13 is slidably disposed on the support arm 12. A support rod 22 is disposed between the slider 13 and the vertical cylinder 9. The two ends of the support rod 22 are respectively hinged to the slider 13 and the kit 19.

[0034] The slider 13 is fixed with a vertical arm 1301. The elastic component includes two guide posts 14 slidably disposed on the vertical arm 1301, a connecting block 15 fixedly connecting the two guide posts 14, and a second spring 17 sleeved on the outer periphery of the guide posts 14. The two ends of the second spring 17 are respectively connected to the vertical arm 1301 and the connecting block 15. The limiting block 18 is rotatably installed on the side of the connecting block 15 away from the vertical arm 1301.

[0035] During operation, the movable end of the second cylinder 20 extends, thereby driving the follower frame 21 to slide the kit 19 downward on the vertical cylinder 9. Correspondingly, the kit 19 pulls the slider 13 on the support arm 12 toward the vertical cylinder 9 through the support rod 22. The limiting block 18 moves closer to the pipe. After the limiting block 18 contacts the pipe, it gradually limits the pipe, making the pipe centered. As the movable end of the second cylinder 20 continues to move, the vertical arm 1301 will move relative to the connecting block 15. The second spring 17 is compressed. During this process, the transmission mechanism is triggered, causing the two clamping members 25 to move closer to each other on the turntable 27, that is, to move toward the pipe at the same time to clamp the pipe. Furthermore, after the clamping member 25 acts on the pipe, since the pipe is tilted at a certain angle in the length direction of the base 1, the two clamping members 25 will cause the pipe to gradually shift towards a vertical state during the clamping process. Correspondingly, the pipe will drive the limiting block 18 to rotate.

[0036] Please refer to it again. Figure 8 and Figure 10 The turntable 27 has a radially arranged through groove 2701. The transmission mechanism includes a driven block 24 slidably fitted into the through groove 2701. The clamping member 25 is fixedly connected to the driven block 24. A sliding fit structure is provided between the driven block 24 and the kit 19. The sliding fit structure includes a driven plate 26 fixed to the bottom of the driven block 24 and a drive arm 23 fixed to the kit 19. A drive column 2301 is fixedly provided on the drive arm 23, and a groove adapted to the drive column 2301 is provided on the driven plate 26. The drive column 2301 is located in the groove and slidably connected to the driven plate 26. The groove includes a vertical groove 2601 and an inclined groove 2602 connected together.

[0037] Specifically, during the downward sliding of the assembly 19 on the vertical cylinder 9 by the moving end of the second cylinder 20 driven by the follower frame 21, the second spring 17 is compressed. During the initial compression of the second spring 17, the limiting block 18 exerts a certain limiting force on the pipe to prevent the pipe from shifting in the width direction of the base 1. Correspondingly, the assembly 19 drives the drive column 2301 to slide in the vertical groove 2601 toward the inclined groove 2602 via the drive arm 23. Finally, the drive column 2301 will enter the inclined groove 2602 and slide with the driven plate 26 through the inclined groove 2602. The driven plate 26 then drives the driven block 24 to move aside. The driven block 24 drives the clamping member 25 to move toward the pipe along the through groove 2701, so as to cause the pipe to deflect along the length direction of the base 1 and correct it to a vertical state, ensuring the smooth progress of subsequent laser detection.

[0038] Please refer to it again. Figure 9 The supporting structure includes a telescopic shaft 10 that slides and fits with the vertical cylinder 9. The vertical cylinder 9 is also provided with a first spring 16. One end of the first spring 16 is connected to the inner wall of the vertical cylinder 9, and the other end is connected to the head end of the telescopic shaft 10. The tail end of the telescopic shaft 10 is fixed with a supporting member 11. The outer wall of the telescopic shaft 10 is provided with two strip-shaped protrusions 1001, and the inner wall of the vertical cylinder 9 is provided with two strip-shaped grooves 901 that are adapted to the strip-shaped protrusions 1001.

[0039] After the robotic arm places the pipe to be tested into the through-hole on the turntable 27, the support member 11 can support the bottom end of the pipe. It should be noted that a certain distance is reserved between the support member 11 and the turntable 27, and the height of the limiting block 18 is between the support member 11 and the turntable 27. In detail, the strip groove 901 and the strip protrusion 1001 are parallel to the central axis of the vertical cylinder 9 and the telescopic shaft 10. The arrangement of the strip groove 901 and the strip protrusion 1001 serves two purposes. First, when the adjusting mechanism drives the vertical cylinder 9 to rotate, the vertical cylinder 9 can drive the telescopic shaft 10 and the support member 11 to rotate together, ensuring that the pipe remains relatively stationary with respect to the support member 11 when it rotates. Second, when the clamping member 25 acts on the pipe, causing the pipe to switch from an inclined state to a vertical state, the bottom end of the pipe will apply downward pressure to the support member 11, thereby causing the support member 11 to move downward, the first spring 16 to be compressed, and the strip groove 901 and the strip protrusion 1001 to play a guiding role.

[0040] Please refer to it again. Figure 6 and Figure 9The adjustment mechanism includes a motor 7 installed on the side of the clamping table 4. The output shaft of the motor 7 extends into the clamping table 4 and is connected to the vertical cylinder 9 through a bevel gear set 8.

[0041] To elaborate, the bevel gear set 8 includes a first bevel gear fixedly installed at the rear end of the output shaft of the motor 7 and a second bevel gear fixedly installed on the vertical cylinder 9, wherein the second bevel gear meshes with the first bevel gear; After the pipe fitting is clamped, the laser scanner 3, after completing the first stage of operation, determines whether the cut hole on the pipe fitting is aligned with the laser scanner 3 and calculates the angle difference between the cut hole and the inspection surface of the pipe fitting. Subsequently, the motor 7, based on the results of the first stage of operation of the laser scanner 3, drives the vertical cylinder 9 to rotate by a corresponding angle through the bevel gear set 8. Then, the limiting block 18 and the clamping member 25 simultaneously perform circular motion, and the turntable 27 rotates until the inspection surface of the pipe fitting is rotated to a position aligned with the laser scanner 3, so that the inspection work can be carried out smoothly.

[0042] Please refer to it again. Figure 4 The base 1 has a first guide groove 101 along its own length direction, a transverse sliding seat 5 is slidably provided on the first guide groove 101, and a second guide groove 501 is provided on the transverse sliding seat 5 along the width direction of the base 1. The clamping table 4 is slidably provided on the second guide groove 501. The transverse sliding seat 5 can be driven by a threaded drive mechanism provided on the base 1 to move along the first guide groove 101. A first cylinder 6 is also fixed on the transverse sliding seat 5, and the movable end of the first cylinder 6 is fixed to the clamping table 4.

[0043] Specifically, the threaded drive mechanism adopts a screw and threaded sleeve drive form. Through the threaded engagement, the transverse moving seat 5 can be driven to move along the first guide groove 101. Thus, during the inspection process, the distance between the clamping table 4 and the stand 2 can be effectively adjusted, realizing the adjustability of the distance between the pipe fitting and the laser scanner 3. Different pipe fittings may have different diameters and wall thicknesses. By adjusting the distance, it is ensured that the laser scanning device can accurately align with the round hole, thereby realizing the universal inspection of pipe fittings of various sizes. Secondly, for the movement of the laser scanner 3 along the height direction of the stand 2, a threaded drive method can also be adopted to improve the stability of the scanning action of the laser scanner 3; When the first cylinder 6 is working, it can drive the clamping table 4 to move along the second guide groove 501, thus enabling fine adjustment of the position of the pipe in the width direction of the base 1, improving the flexibility of the inspection.

[0044] As another embodiment of the present invention, a method for detecting the eccentricity of the cut hole in a towel rack fitting using the aforementioned detection device is also proposed, comprising the following steps: Step 1: The robotic arm places the pipe to be tested into the guide port on the turntable 27, and the supporting structure supports the bottom end of the pipe. Step two: The power mechanism operates, driving the two limiting blocks 18 to approach the pipe fitting, limiting the pipe fitting and centering it. Step 3: The transmission mechanism is triggered, causing the two clamping parts 25 to act on the pipe, so that the pipe is corrected from an inclined state to a vertical state. Step 4: The laser scanner 3 scans the pipe fitting, determines the deviation angle of the detection surface of the pipe fitting, and the adjustment mechanism drives the clamping part 25 and the limiting block 18 to rotate the pipe fitting until the detection surface of the pipe fitting is directly facing the laser scanner 3. Step 5: The laser scanner 3 moves along the height direction of the stand 2 to scan the holes on the pipe one by one. Through AI analysis, it is determined whether the eccentricity of the holes on the pipe is qualified.

10. A method for detecting the eccentricity (AI) of a cut hole in a towel rack fitting, using the detection device as described in any one of claims 1-9, characterized in that... Includes the following steps: Step 1: The robotic arm places the pipe to be tested into the guide port on the turntable, and the supporting structure supports the bottom end of the pipe. Step two: The power mechanism operates, driving the two limiting blocks closer to the pipe fitting to limit the pipe fitting and center it. Step 3: The transmission mechanism is triggered, causing the two clamping parts to act on the pipe, so that the pipe is corrected from an inclined state to a vertical state; Step 4: The laser scanner scans the pipe fitting, determines the deviation angle of the detection surface of the pipe fitting, and the adjustment mechanism drives the clamping part and the limiting block to rotate the pipe fitting until the detection surface of the pipe fitting is directly facing the laser scanner. Step 5: The laser scanner moves along the height of the stand to scan the holes on the pipe one by one. Through AI analysis, it is determined whether the eccentricity of the holes on the pipe is up to standard.
