Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing, specifically to an intelligent correction device for pipe fitting welds based on vision inspection. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection involves using machine vision products to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution, brightness, color, and other information, these signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. Many pipe fittings require visual inspection at their weld seams before leaving the factory to ensure that the pipe fittings meet quality standards.

[0003] Traditional pipe fitting weld inspection equipment has the following shortcomings: First, many traditional pipe fitting weld inspection equipment uses semi-automatic equipment for inspection, making it difficult to achieve fully automated operation. For example, inspection still relies on manual visual inspection or auxiliary inspection, and the loading and unloading of workpieces during the inspection process also mostly requires manual assistance, resulting in high labor costs and low efficiency. Moreover, many inspection equipment have a narrow inspection range and cannot inspect the corresponding positions of the workpiece from multiple angles, which can easily lead to omissions during the inspection process. Therefore, it is necessary to design a new type of inspection equipment to solve these problems. Summary of the Invention

[0004] Therefore, it is necessary to provide a vision-based intelligent correction device for pipe weld seams to address the existing technical problems.

Detailed Implementation

[0047] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0048] refer to Figures 1 to 10 The illustrated intelligent correction device for pipe fitting welds based on vision inspection includes:

[0049] The long base includes a storage area 1 and a detection area 2 arranged horizontally adjacent to each other. Several bearing members 3 are arranged at equal intervals along the length of the detection area 2, and the top of the bearing member 3 on the side away from the storage area 1 is provided with a sloping part 5.

[0050] The feeding assembly includes several receiving belts and a driving mechanism set on a long base. Several long strips of material 6 are set on several receiving belts and located in the storage area 1. The driving mechanism is used to drive several receiving belts to feed several long strips of material 6 onto several carriers 3.

[0051] The detection component 7 includes a side fixing seat 8 fixedly disposed vertically on one side of the detection area 2 in the width direction, a monitoring component fixedly disposed on the side fixing seat 8, and a rotating clamp axially disposed on the side fixing seat 8 for fixing the long strip material 6.

[0052] The longitudinal conveying mechanism 10 is fixedly mounted horizontally on several carriers 3, and is used to convey several long strips of material 6 on the carriers 3 to the top of the carriers 3 near the inclined surface 5.

[0053] The transverse feeding assembly includes a feeding mechanism 11 that is horizontally fixed on the side of the detection area 2 away from the detection assembly 7 and is used to push the long strip material 6 toward the detection assembly 7, and a unloading mechanism that is fixed on the side fixing seat 8 and is used to push the long strip material 6 toward the feeding mechanism 11.

[0054] Several intercepting mechanisms 12 are evenly distributed along the length of the long base and are fixedly installed on the detection area 2. Each intercepting mechanism 12 has an intercepting member 13 that extends perpendicularly to the inclined surface 5 and is used to intercept the long strip of material 6 on the inclined surface 5.

[0055] The feeding assembly includes several receiving parts that are equally spaced along the length of the detection area 2 and move vertically up and down, and a feeding mechanism 14 that is fixedly set along the length of the detection area 2 and used to move the detected long strip material 6 away from the long strip base.

[0056] The storage area 1 has a vertical side sealing baffle 15 near the side fixing seat 8 to prevent the long strip of material 6 from falling out. The receiving belt is a nylon belt 4, and the height of the fixed position of the nylon belt 4 at the end of the storage area 1 away from the detection area 2 is higher than the height of the fixed position of the nylon belt 4 at the end of the detection area 2. The side fixing seat 8 has an opening in the middle, and a fixed disc 16 is fixedly connected to the side of the side fixing seat 8 near the feeding mechanism 11. The monitoring device is an industrial camera 9 fixedly mounted on the fixed disc 16 by a fixed bracket 17. The industrial camera 9 is hinged to the fixed bracket 17 and fixed on the fixed bracket 17, so as to facilitate the adjustment of the angle of the industrial camera 9 to ensure that the industrial camera 9 can monitor the corresponding end of the long strip of material 6. The rotating clamp The device includes a rotating mechanism and a centering fixture. The rotating mechanism includes a rotating disk 18 axially mounted on a fixed disk 16 and a stepper motor 19 fixedly mounted on a side fixed seat 8 away from the feeding mechanism 11. The output shaft of the stepper motor 19 passes through the side fixed seat 8 with one end facing the feeding mechanism 11. A driven gear 20 is fixedly connected to the rotating disk 18. A drive gear 21 is fixedly connected to the output shaft of the stepper motor 19, and the external teeth of the drive gear 21 mesh with the external teeth of the driven gear 20. The centering fixture includes two sets of transverse limiting wheels 22 and two sets of longitudinal limiting wheels 23 symmetrically arranged on the rotating disk 18. Several long strips of material 6 are first placed in the storage area 1. Several nylon straps 4 are stacked on the material storage area 1. Then, a drive mechanism drives the nylon straps 4 to simultaneously wind and tighten at one end of the detection area 2. Because the nylon straps 4 are fixed at a higher position at the storage area 1, several long strips of material 6 can be tightened and lifted using the nylon straps 4 in the storage area 1. The corresponding long strips of material 6 are then moved onto several carriers 3 in the detection area 2. A height limiting mechanism is also provided near the storage area 1 in the detection area 2. The height limiting mechanism includes a limiting crossbar 24 along the length of the long strip base and a vertical lifting mechanism 25 for driving the limiting crossbar 24 to rise and fall. The height of the limiting crossbar 24 can be preset before moving the long strips of material 6 using the nylon straps 4, thereby ensuring that the long strips of material 6 enter the detection area 2. Only one item can enter at a time. When the cross-section of the long strip material 6 is a rectangle with varying lengths and widths, if the limiting crossbar 24 is moved to a suitable height, it can ensure that the cross-sectional shape of the long strip material 6 remains with the wide side facing down and the two narrow sides facing to the sides when entering the detection area 2. This ensures the consistency of the fixed state of each long strip material 6 during subsequent detection, which is more conducive to subsequent detection. At the same time, the limiting crossbar 24 can also be pressed down after a specified number of long strip materials 6 have been sent into the detection area 2 to prevent excess long strip materials 6 from entering. After the long strip material 6 is sent into the detection area 2, it is conveyed to a designated position by the longitudinal conveying mechanism 10. Then, the longitudinal conveying mechanism 10 stops conveying, and the feeding mechanism 11 then pushes the long strip material 6 to the detection component 7.Two sets of lateral limiting wheels 22 and two sets of longitudinal limiting wheels 23, in conjunction with the industrial camera 9, clamp the corresponding ends of the long strip material 6. The industrial camera 9 then begins to inspect these ends. Subsequently, if necessary, a stepper motor 19 can be used to rotate the long strip material 6, allowing the industrial camera 9 to perform a more comprehensive inspection. After the long strip material 6 has been completely inspected, the pushing mechanism pushes it out. After the long strip material 6 returns to its original position, the longitudinal conveying mechanism 10 continues to convey several more long strip materials 6. The inspected long strip materials 6 are then conveyed to the inclined surface 5 of the carrier 3, where the intercepting mechanism 12 intercepts them, and the process continues with the next long strip material. The detection of material 6 and subsequent synchronous material detection are the same as described above, and will not be repeated here. After the long strip material 6 is fed onto the inclined surface 5 and stopped by the stopping mechanism 12, several receiving components will rise vertically to a designated position. Then, the stopping mechanism 12 releases its interception of the long strip material 6, allowing it to slide down the inclined surface 5 onto several receiving components. The stopping mechanism 12 then returns to its original position to wait for the next long strip material 6. After receiving the long strip material 6, the receiving components descend vertically, placing the long strip material 6 onto the unloading mechanism 14 and sending it out of the long strip base. The subsequent conveying, detection, and delivery methods for each long strip material 6 are the same as described above.

[0057] One end of the receiving belt is fixedly installed at the top of the storage area 1 on the side away from the detection area 2. Several carriers 3 are axially connected to the top of the side of the storage area 1 with a first rotating shaft 26 along the length of the long base. The driving mechanism includes a second rotating shaft 27 that is horizontally connected to several carriers 3 and parallel to the first rotating shaft 26, and a first reducer 28 that is horizontally fixed on the detection area 2. The output shaft of the first reducer 28 is fixedly connected to one end of the second rotating shaft 27. Several first winding discs 29 and second winding discs 30, which correspond one-to-one with the receiving belt, are respectively axially connected and fixedly connected to the first rotating shaft 26 and the second rotating shaft 27. The other end of each receiving belt passes over the corresponding first winding disc 29 and is fixedly connected to the corresponding second winding disc 30.

[0058] One end of the nylon belt 4 is fixedly set at the top of the end of the storage area 1 away from the detection area 2, and the other end is bent downward through a corresponding winding disc and fixed on the corresponding second winding disc 30. The part of the storage area 1 where the nylon belt 4 is fixed is higher than the height of the first winding disc 29, so that the middle part of the nylon belt 4 bends downward and hangs in the storage area 1 to form a V-shaped structure, which facilitates the suspension of several long strips of material 6. When the first reducer 28 drives the second rotating shaft 27 to rotate, the second rotating shaft 27 drives the second winding disc 30 to wind around the corresponding end of the nylon belt 4. The nylon belt 4 rotates on the first winding disc 29, which drives the part of the long strip of material 6 located in the detection area 2 to lift up and then send the long strip of material 6 to the top of several carriers 3.

[0059] The longitudinal conveying mechanism 10 includes:

[0060] A third rotating shaft 31, parallel to the first rotating shaft 26, is horizontally mounted on several bearing members 3 and located at the top of the bearing member 3 near the inclined part 5. The third rotating shaft 31 and the first rotating shaft 26 are at the same height, and several sets of spaced drive sprockets are fixedly connected to the third rotating shaft 31 and the first rotating shaft 26.

[0061] The second reducer 32 is horizontally fixed on one of the bearing members 3 by the first side fixing bracket 33, and the output shaft of the second reducer 32 is fixedly connected to the first gear 34. The corresponding position of the third rotating shaft 31 is fixedly connected to the second gear 35, and the first gear 34 and the second gear 35 are fixedly connected by the first chain 36.

[0062] After the second reducer 32 drives the first gear 34 to rotate, the first gear 34 drives the second gear 35 to rotate through the first chain 36, and then drives the entire third shaft 31 to rotate through the second gear 35. The third shaft 31 drives several drive sprockets to rotate, and then drives several long strips of material 6 on it to move towards the inclined surface 5.

[0063] Each set of drive sprockets includes a first double-row gear 37 and a second double-row gear 38 fixedly mounted on the first shaft 26 and the third shaft 31, and a double-row chain 39 for fixing the first double-row gear 37 and the second double-row gear 38 together. After the third shaft 31 rotates, it drives the second double-row gear 38 to rotate, which in turn drives the first double-row gear 37 to rotate through the second double-row gear 38 and the double-row chain 39, thereby driving the first shaft 26 to rotate. Since the long strip of material 6 is mounted on several double-row chains 39, the movement of the double-row chains 39 will drive the long strip of material 6 to move forward.

[0064] The feeding mechanism 11 includes:

[0065] The first long-shaft cylinder 40 is fixedly mounted on the detection area 2 by the second side fixing bracket 41 and the output shaft of the first long-shaft cylinder 40 points horizontally toward the detection component 7.

[0066] The first pusher plate 42 is fixedly mounted vertically on the output shaft of the first long shaft cylinder 40;

[0067] The guide rod 43 is slidably mounted on the second side fixing frame 41 via a horizontal linear bearing 44, and one end of the guide rod 43 is fixedly connected to the first pusher plate 42.

[0068] The first long-shaft cylinder 40 can smoothly push the first pusher plate 42 to move through the limit of the guide rod 43. The double-row chain 39 drives the corresponding long strip material 6 to move to the position directly opposite the first pusher plate 42 and stops moving when the first pusher plate 42 does not push the next long strip material 6. Then the first pusher plate 42 will push the long strip material 6 to the detection component 7 for detection.

[0069] The unloading mechanism is a second long-shaft cylinder 45, which is fixedly mounted on the side of the side fixing seat 8 away from the feeding mechanism 11 via a fixed back plate 46. The output shaft of the second long-shaft cylinder 45 passes through the side fixing seat 8, and a second pusher plate 47 is fixedly connected to the output shaft of the second long-shaft cylinder 45. The second long-shaft cylinder 45 can push the inspected long strip material 6 back to its original position via the second pusher plate 47, which facilitates the subsequent pushing of the long strip material 6 to the inclined surface 5.

[0070] The stopping component 13 includes a rectangular plate 48 and an L-shaped intercepting baffle 49. The rectangular plate 48 is fixedly connected to the intercepting baffle 49, and the long end of the intercepting baffle 49 is parallel to the inclined surface 5. The short end of the intercepting baffle 49 is perpendicular to its long end and points towards the inclined surface 5. Each stopping mechanism 12 also includes:

[0071] A single-axis cylinder 50 is fixedly mounted on the detection area 2 by a diagonal support bracket 51. The output shaft of the single-axis cylinder 50 points to the inclined surface 5 and is fixedly connected to the corresponding rectangular plate 48.

[0072] The limiting optical axis 52 is slidably mounted on the inclined support bracket 51 via an inclined linear bearing 53 perpendicular to the inclined surface 5, and one end of the limiting optical axis 52 is fixedly connected to the rectangular plate 48.

[0073] Since the long strip of material 6 will slide down the inclined surface 5 after being pushed to it, the single-axis cylinder 50 drives the rectangular plate 48 and the intercepting baffle 49 to extend towards the inclined surface 5. Since the rectangular plate 48 is set parallel to the inclined surface 5 and the intercepting baffle 49 is set perpendicular to the rectangular plate 48, when the long strip of material 6 slides down the inclined surface 5, if the output shaft of the single-axis cylinder 50 extends a sufficient distance, the intercepting baffle 49, together with the rectangular plate 48 and the inclined surface 5, can intercept the long strip of material 6 on the inclined surface 5 and prevent it from falling.

[0074] Each receiving component includes a receiving plate 54 with a right-angled triangular cross-section and an inclined baffle 55. The inclined baffle 55 is fixedly connected to the receiving plate 54 via a support frame 56 fixed below it, perpendicular to the top of the receiving plate 54. Several third long-shaft cylinders 57, each corresponding to the receiving plate 54, are also fixedly connected in the detection area 2. The output shaft of the third long-shaft cylinder 57 is vertically upward and fixedly connected to the bottom of the receiving plate 54. Each third long-shaft cylinder 57 is also provided with a limiting vertical shaft 58 on its side. The limiting vertical shaft 58 is slidably mounted on the detection area 2 via a vertical linear bearing 59. The top of the limiting vertical shaft 58 is fixedly connected to the bottom of the corresponding receiving plate 54. The top of the receiving plate 54 is parallel to the inclined surface 5 or the slope is slightly gentler than the inclined surface 5. After the third long shaft cylinder 57, in conjunction with the limiting vertical shaft 58, lifts the receiving plate 54 a sufficient distance, and the intercepting baffle 49 is retracted by the single shaft cylinder 50, the long strip material 6 can roll through the inclined surface 5 onto the inclined surface of the receiving plate 54. Then the long strip material 6 slides down to the inclined baffle 55 and is blocked, which facilitates the subsequent transport of the long strip material 6.

[0075] The feeding mechanism 14 includes:

[0076] Several horizontal rollers 60 are evenly distributed along the length of the detection area 2. Each horizontal roller 60 is parallel to the width of the detection area 2 and both ends of the horizontal roller 60 are axially connected to the detection area 2 through two bearing seats 61.

[0077] The third reducer 62 is fixedly installed horizontally on the detection area 2. One end of each horizontal roller 60 is fixedly connected to a third double-row gear 63. The output shaft of the third reducer 62 is connected to the third double-row gear 63 on one end of the horizontal roller 60 through a third gear 64 and a second chain 65. Adjacent third double-row gears 63 are connected through a third chain 66.

[0078] When the receiving plate 54 receives the long strip of material 6, the output shaft of the third long shaft cylinder 57 retracts, causing the receiving plate 54 to descend vertically. After the long strip of material 6 is lowered a sufficient distance, it will fall onto several horizontal rollers 60. Subsequently, the receiving plate 54 continues to descend until it completely detaches from the long strip of material 6. The third reducer 62 drives the corresponding horizontal roller 60 to rotate through the third gear 64, the second chain 65 and the corresponding third double row gear 63. Then, several third chains 66 cooperate with the corresponding third double row gear 63 to drive the remaining horizontal rollers 60 to rotate synchronously, thereby driving the long strip of material 6 to leave the long strip base along its length direction.

[0079] Each of the horizontal rollers 60 is fitted with an anti-wear sleeve 67 in the middle. The anti-wear sleeve 67 can be made of an elastic material with high surface friction, which can move the long strip of material 6 more smoothly while taking into account wear resistance.

[0080] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
