Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically a welding device for a pipe support system. Background Technology

[0002] Pipe support systems are comprehensive structures specifically designed to support, fix, and protect pipelines and their internal media. Their core function is to ensure the safe, stable, and reliable operation of pipelines under various operating conditions (such as thermal expansion, pressure, and vibration), and to precisely control the position and displacement of the pipeline. In some cases, during the manufacturing process, pipe clamps and supports are often welded together to provide stronger connection rigidity.

[0003] In existing technologies, when welding pipe clamps and supports, the two parts need to be aligned at a specific angle before a welding robot welds the joint. However, in some cases, batch welding of pipe clamps and supports is required. Frequent manual alignment of pipe clamps and supports leads to high labor intensity for workers and is prone to alignment deviations, thus affecting welding quality. Using a robotic arm to replace workers for alignment presents new problems: the pipe clamps and supports to be welded may be in a disorderly piled-up state when transferred from the previous process. The robotic arm needs a vision positioning device to identify the outline of the pipe clamps and supports before gripping them. This disorderly piled-up state can cause workpieces to overlap, making vision positioning difficult and leading to gripping failures or improper gripping angles, thus affecting welding quality and efficiency.

[0015] The beneficial effects of this invention are as follows: 1. The welding device for a pipe support system described in this invention utilizes a preliminary fixing auxiliary component and a material transfer and positioning component to achieve automatic feeding and docking of pipe clamps and supports, eliminating the need for manual feeding and docking by workers, thus saving time and effort. Furthermore, compared to directly gripping pipe clamps and supports with a robotic arm, this method arranges the clamps and supports in a horizontally aligned state before gripping them, and then uses visual recognition technology to identify their angles. The gripper cylinder then moves precisely along a preset trajectory to accurately grip the clamps and supports, avoiding visual positioning difficulties caused by cluttered workpieces, which could lead to gripping failures or improper gripping angles, thus ensuring continuous welding quality and efficiency.

[0016] 2. The welding device for a pipe support system of the present invention utilizes a sliding facilitator. When the pipe clamp and support are placed at the limiting plate, the scraper can be driven to slide laterally back and forth. The scraper pushes the pipe clamp and support stuck above the feeding channel, causing their angles to change in real time until they fall into the feeding channel. This avoids the situation where the pipe clamp and support are stuck above the feeding channel due to improper angles, thus affecting subsequent feeding.

[0017] 3. The welding device for a pipe support system described in this invention utilizes a first unblocking component and a second unblocking component to change the angle of the pipe clamps and supports stuck at the baffle plate through the intermittent movement of the lifting block and the jacking rod, until the angle meets the passage requirements and they can smoothly pass under the baffle plate, thereby ensuring the continuity of the material supply process. Simultaneously, because the lifting block and the jacking rod move intermittently, with a pause after each movement, it does not affect the normal passage of pipe clamps and supports whose angles already meet the requirements.

A rotating block 37 is rotatably set at one end of the connecting block 35. A gripper cylinder 38 is fixedly connected to one side of the rotating block 37.

[0023] In this embodiment, as Figure 2 , Figure 3 , Figure 6 , Figure 8 , Figure 11 As shown, a bidirectional threaded rod 16 is rotatably provided on one side of the back plate 3. The two sides of the bidirectional threaded rod 16 are respectively threaded to the two limit plates 4 on both sides. A motor 17 is fixedly connected to one side of the back plate 3. The output end of the motor 17 is fixedly connected to one end of the bidirectional threaded rod 16. A cylinder 11 is fixedly connected to one side of the back plate 3. The piston end of the cylinder 11 is fixedly connected to one end of the connecting column 12.

[0024] A stop bar 14 is rotatably mounted on one side of the frame 6, and a motor 15 is fixedly connected to one side of the frame 6. The output end of the motor 15 is fixedly connected to one end of the stop bar 14.

[0025] The lower end of the transverse plate 7 is threadedly connected to a threaded rod 28. Both ends of the threaded rod 28 are rotatably mounted on the base 1. A motor 29 is fixedly connected to one side of the upper surface of the base 1. The output end of the motor 29 is fixedly connected to one end of the threaded rod 28. One end of the slider 32 is threadedly connected to a threaded rod 31. Both ends of the threaded rod 31 are rotatably mounted on the crossbeam 8. A motor 30 is fixedly connected to one side of the upper end of the crossbeam 8. The output end of the motor 30 is fixedly connected to one end of the threaded rod 31.

[0026] A cylinder 33 is fixedly connected to one side of the slider 32. The piston end of the cylinder 33 is fixedly connected to one side of the connecting block 35. A motor 36 is fixedly connected to one side of the connecting block 35. The output end of the motor 36 is fixedly connected to one end of the rotating block 37.

[0027] A motor 44 is fixedly connected to one side of the rotating block 37, and the output end of the motor 44 is fixedly connected to one end of the gripper cylinder 38.

[0028] Specifically, in existing technologies, when welding pipe clamps and supports, the two need to be aligned at a specific angle before a welding robot 5 welds the joint. However, in some cases, batch welding of pipe clamps and supports is required. Frequent manual alignment of pipe clamps and supports leads to high labor intensity for workers and is prone to alignment deviations, thus affecting welding quality. When a robotic arm replaces workers for alignment, new problems arise: the pipe clamps and supports to be welded may be in a disorderly piled-up state when transferred from the previous process. The robotic arm needs to rely on a vision positioning device to identify the outline of the pipe clamps and supports before gripping them. This disorderly piled-up state can cause the workpieces to overlap, making vision positioning difficult and leading to gripping failures or improper gripping angles, thus affecting welding quality and efficiency.

[0029] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: This solution is applied to welding pipe clamps and supports of the same specifications in the same batch, where the main body of the pipe clamp is semi-circular and the main body of the support is cuboid. The narrowest distance between two adjacent limiting plates 4 is used as the feeding channel, with the left feeding channel used to place the pipe clamp and the right feeding channel used to place the support.

[0030] Furthermore, the bidirectional threaded rod 16 can be rotated by motor 17, causing the two limiting plates 4 to slide simultaneously, adjusting the width of the feeding channel, and making the width of the feeding channels on both sides equal to the width of the pipe clamp and the width of the support, respectively. The pipe clamp and support transferred from the previous process are placed above the feeding channels on both sides, and they will slide down along the limiting plates 4 under gravity. Since the width of the feeding channels on both sides is equal to the width of the pipe clamp and the width of the support, the pipe clamp and support entering the feeding channel are in an upright state. Additionally, the connecting column 12 can be raised and lowered by cylinder 11, adjusting the distance between the bottom edge of the two side blocking plates 9 and the surface of the conveyor belt 13, making this distance equal to the radius of the pipe clamp and the minimum height of the support when it is upright. Then, the conveyor belt 13 is driven to operate, which in turn moves the pipe clamps and supports in the feeding channel. Due to the restriction of the baffle plate 9, only one pipe clamp or support can pass under the baffle plate 9 at a time. Therefore, the pipe clamps and supports passing under the baffle plate 9 will be arranged horizontally in the feeding channel. As the pipe clamps and supports move, they will be blocked by the stop bar 14. Then the conveyor belt 13 stops operating, and the motor 15 drives the stop bar 14 to rotate, so that the stop bar 14 no longer blocks the pipe clamps and supports. At this time, the vision detection device on the welding robot 5 will identify the angle of the blocked pipe clamps and supports and upload the angle information to the control system. The control system, based on the angle information of the pipe clamp and support, uses motor 5 (29) to drive threaded rod 3 (28) to rotate, motor 6 (30) to drive threaded rod 4 (31) to rotate, and cylinder 4 (33) to lift and lower connecting block 35. This adjusts the position of gripper cylinder 38 in the x, y, and z axes, aligning the gripping ends of the two gripper cylinders 38 with the edges of the pipe clamp and support respectively. The gripper cylinders 38 then clamp the two components. Motor 7 (36) drives rotating block 37 to rotate, and motor 9 (44) drives gripper cylinder 38 to rotate, adjusting the angle of both components and placing them on welding table 2. The pipe clamp and support are then aligned at a specific angle. At this point, welding robot 5 can weld the pipe clamp and support according to a preset trajectory. After welding, the finished product is removed from welding table 2, and the above operation is repeated to continuously weld multiple pipe clamps and supports. This achieves automatic feeding and alignment of pipe clamps and supports, eliminating the need for manual feeding and alignment by workers, making it more convenient and labor-saving. Furthermore, compared to directly gripping pipe clamps and supports with a robotic arm, this method arranges the pipe clamps and supports into a horizontally aligned state before gripping them. Then, visual recognition technology is used to identify the angle between the two. The gripper cylinder 38 can accurately grip the pipe clamps and supports by moving only according to a preset trajectory. This avoids visual positioning difficulties caused by messy workpiece accumulation, which could lead to gripping failure or improper gripping angle, thus ensuring continuous welding quality and efficiency.

[0031] In this embodiment, as Figures 2-5 As shown, it also includes a slip-promoting component; The slip-promoting component includes a scraper 10 slidably connected to one side of the limiting plate 4. The scraper 10 is in contact with the surface of one side of the limiting plate 4. One end of the scraper 10 is threadedly connected to a threaded rod 18. Both ends of the threaded rod 18 are rotatably mounted on the limiting plate 4. A motor 19 is fixedly connected to one side of the limiting plate 4. The output end of the motor 19 is fixedly connected to one end of the threaded rod 18.

[0032] Specifically, in the above embodiments, although the feeding channel can be used to arrange the clamps and supports for subsequent clamping, the clamps and supports need to fall into the feeding channel at a specific angle. When the angle of the clamps and supports does not meet the falling conditions, the clamps and supports will get stuck above the feeding channel, thus affecting the subsequent feeding.

[0033] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the pipe clamp and support are placed at the limit plate 4, the scraper 10 can be moved laterally back and forth by the motor 319 driving the threaded rod 18 to rotate. The scraper 10 pushes the pipe clamp and support stuck above the feeding channel, so that their angles change in real time until they fall into the feeding channel. This avoids the situation where the pipe clamp and support get stuck above the feeding channel due to improper angles, which would affect the subsequent feeding.

[0034] In this embodiment, as Figure 2 and Figure 10 As shown, a first unblocking component is also provided on the left-side baffle plate 9; The first unblocking component includes two guide rods 23 slidably connected to one side of the baffle plate 9. A fixing block 25 is fixedly connected to the lower end of the guide rod 23. A cylinder 26 is fixedly connected to one side of the fixing block 25. A lifting block 27 is fixedly connected to the piston end of the cylinder 26. A cylinder 24 is fixedly connected to one side of the baffle plate 9. The piston end of the cylinder 24 is fixedly connected to one side of the fixing block 25.

[0035] A second unblocking component is also installed on the right-side frame 6; The second unblocking component includes a limiting rod 39 fixedly connected to one side of the frame 6. The limiting rod 39 is slidably connected to a lifting plate 22. A lifting rod 40 is fixedly connected to the middle of the lifting plate 22. A pulley 41 is rotatably provided at the upper end of the lifting rod 40. The frame 6 is also provided with a through hole 43 for the lifting rod 40 to pass through.

[0036] One end of the lifting plate 22 is threadedly connected to a threaded rod 21. One end of the threaded rod 21 is rotatably mounted on the frame 6. A motor 40 is fixedly connected to one side of the frame 6. The output end of the motor 40 is fixedly connected to one end of the threaded rod 21. A motor 82 is fixedly connected to one side of the upper end of the lifting rod 40. The output end of the motor 842 is fixedly connected to the middle of the pulley 41.

[0037] Specifically, in the above embodiments, although the baffle plate 9 can be used to block the pipe clamps and supports, allowing only one pipe clamp or support to pass under the baffle plate 9 at a time, jamming can easily occur when the height of the pipe clamps and supports exceeds the bottom of the baffle plate 9. Furthermore, because the pipe clamps are semi-circular, when two pipe clamps overlap and face the same direction, they can easily jam against each other, thus affecting the normal feeding of the pipe clamps and supports.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: The lifting block 27 is moved laterally by cylinder 24, which drives the fixed block 25 to rise and fall, and cylinder 26 drives the lifting block 27 to move laterally. The lifting block 27 can move along a rectangular track. When the lifting block 27 is at its lowest point, it is lower than the bottom edge of the baffle plate 9. Then the lifting block 27 moves laterally and passes through the groove on one side of the baffle plate 9. Then the lifting block 27 rises and then moves out of the groove. When the lifting block 27 intermittently moves along this track, it will contact the protrusion on the edge of the pipe clamp and lift the pipe clamp that cannot pass through the baffle plate 9 due to improper angle. Because the lifted pipe clamp is subjected to uneven force, the pipe clamp will flip after rising to a certain height, changing its angle. At the same time, in conjunction with the operation of the conveyor belt 13, the pipe clamp can pass smoothly under the baffle plate 9.

[0039] Similarly, the motor 420 drives the threaded rod 21 to rotate, causing the lifting plate 22 to move up and down reciprocally. The lifting rod 40 will intermittently pass through the through hole 43. When the support is stuck at the blocking plate 9, the lifting rod 40 will lift it up and cause the support to move upward away from the feeding channel. Then, the motor 82 drives the pulley 41 to rotate. By the friction between the pulley 41 and the bottom of the support, the support will be disengaged from the top of the lifting rod 40 and fall back into the feeding channel. The angle of the support can be changed by making it fall until the support can pass smoothly through the bottom of the blocking plate 9.

[0040] This allows the angles of the pipe clamps and supports stuck at the baffle plate 9 to be changed through the intermittent movement of the lifting block 27 and the lifting rod 40, until their angles meet the requirements for passage, thus ensuring the continuity of the material supply process. Furthermore, since the lifting block 27 and the lifting rod 40 move intermittently, with a pause after each movement, it does not affect the normal passage of pipe clamps and supports whose angles already meet the requirements.

[0041] Working Principle: The narrowest distance between two adjacent limiting plates 4 serves as the feeding channel. The left feeding channel is used to place the pipe clamp, and the right feeding channel is used to place the support. Furthermore, motor 17 drives the bidirectional threaded rod 16 to rotate, causing the two limiting plates 4 to slide simultaneously, adjusting the width of the feeding channels so that the widths of the two feeding channels are equal to the widths of the pipe clamp and the support, respectively. The pipe clamp and support transferred from the previous process are placed above the feeding channels on both sides. Under the influence of gravity, the pipe clamp and support slide down along the limiting plates 4. Since the widths of the two feeding channels are equal to the widths of the pipe clamp and the support, the pipe clamp and support entering the feeding channels are in an upright position. Additionally, cylinder 11 drives the connecting column 12 to rise and fall, adjusting the distance between the bottom edge of the two side blocking plates 9 and the surface of the conveyor belt 13, ensuring that this distance is equal to the radius of the pipe clamp and the minimum height of the support when upright. Then, the conveyor belt 13 is driven to operate, which in turn moves the pipe clamps and supports in the feeding channel. Due to the restriction of the baffle plate 9, only one pipe clamp or support can pass under the baffle plate 9 at a time. Therefore, the pipe clamps and supports passing under the baffle plate 9 will be arranged horizontally in the feeding channel. As the pipe clamps and supports move, they will be blocked by the stop bar 14. Then the conveyor belt 13 stops operating, and the motor 15 drives the stop bar 14 to rotate, so that the stop bar 14 no longer blocks the pipe clamps and supports. At this time, the vision detection device on the welding robot 5 will identify the angle of the blocked pipe clamps and supports and upload the angle information to the control system. The control system, based on the angle information of the pipe clamp and support, uses motor 5 (29) to drive threaded rod 3 (28) to rotate, motor 6 (30) to drive threaded rod 4 (31) to rotate, and cylinder 4 (33) to lift and lower connecting block 35. This adjusts the position of gripper cylinder 38 in the x, y, and z axes, aligning the gripping ends of the two gripper cylinders 38 with the edges of the pipe clamp and support respectively. The gripper cylinders 38 then clamp the two components. Motor 7 (36) drives rotating block 37 to rotate, and motor 9 (44) drives gripper cylinder 38 to rotate, adjusting the angle of both components and placing them on welding table 2. The pipe clamp and support are then aligned at a specific angle. At this point, welding robot 5 can weld the pipe clamp and support according to a preset trajectory. After welding, the finished product is removed from welding table 2, and the above operation is repeated to continuously weld multiple pipe clamps and supports. This achieves automatic feeding and alignment of pipe clamps and supports, eliminating the need for manual feeding and alignment by workers, making it more convenient and labor-saving. Furthermore, compared to directly gripping pipe clamps and supports with a robotic arm, this method arranges the pipe clamps and supports into a horizontally aligned state before gripping them. Then, visual recognition technology is used to identify the angle between the two. The gripper cylinder 38 can accurately grip the pipe clamps and supports by moving only according to a preset trajectory. This avoids visual positioning difficulties caused by messy workpiece accumulation, which could lead to gripping failure or improper gripping angle, thus ensuring continuous welding quality and efficiency.

[0042] When the pipe clamp and support are placed at the limit plate 4, the scraper 10 can be moved laterally back and forth by the motor 319 driving the threaded rod 18 to rotate. The scraper 10 pushes the pipe clamp and support stuck above the feeding channel, so that their angles change in real time until they fall into the feeding channel. This avoids the situation where the pipe clamp and support get stuck above the feeding channel due to improper angles, which would affect the subsequent feeding.

[0043] The lifting block 27 is moved laterally by cylinder 24, which drives the fixed block 25 to rise and fall, and cylinder 26 drives the lifting block 27 to move laterally. The lifting block 27 can move along a rectangular track. When the lifting block 27 is at its lowest point, it is lower than the bottom edge of the baffle plate 9. Then the lifting block 27 moves laterally and passes through the groove on one side of the baffle plate 9. Then the lifting block 27 rises and then moves out of the groove. When the lifting block 27 intermittently moves along this track, it will contact the protrusion on the edge of the pipe clamp and lift the pipe clamp that cannot pass through the baffle plate 9 due to improper angle. Because the lifted pipe clamp is subjected to uneven force, the pipe clamp will flip after rising to a certain height, changing its angle. At the same time, in conjunction with the operation of the conveyor belt 13, the pipe clamp can pass smoothly under the baffle plate 9.

[0044] Similarly, the motor 420 drives the threaded rod 21 to rotate, causing the lifting plate 22 to move up and down reciprocally. The lifting rod 40 will intermittently pass through the through hole 43. When the support is stuck at the blocking plate 9, the lifting rod 40 will lift it up and cause the support to move upward away from the feeding channel. Then, the motor 82 drives the pulley 41 to rotate. By the friction between the pulley 41 and the bottom of the support, the support will be disengaged from the top of the lifting rod 40 and fall back into the feeding channel. The angle of the support can be changed by making it fall until the support can pass smoothly through the bottom of the blocking plate 9.
