Description

Technical Field

[0001] This invention belongs to the technical field of steel structure foot processing, specifically, it relates to a steel structure foot welding device. Background Technology

[0002] The steel structure base is the core load-bearing connection structure for steel columns, poles, and other members. It can bear vertical loads, horizontal shear forces, and overturning moments. Its welding quality directly determines the installation accuracy, load-bearing stability, and service life of the steel structure. The traditional base welding process is relatively simple. First, the base plate is placed on the lower end of the steel structure member. Then, based on construction experience and simple measurement methods, multiple reinforcing ribs are manually arranged along the circumference of the base plate, so that the ribs are respectively attached to the side wall of the member and the surface of the base plate. Finally, the base plate, reinforcing ribs, and member are fully welded and fixed by manual welding or welding robots.

[0003] The primary drawback of this process is poor positioning accuracy. Without dedicated positioning fixtures, the base plate and reinforcing ribs rely entirely on manual visual inspection and alignment. This easily leads to misalignment between the base plate and the end face of the reinforcing ribs, resulting in uneven structural stress, localized stress concentration, and long-term issues such as weld cracking and base plate deformation. Furthermore, the spacing, angle, and verticality of the reinforcing ribs are difficult to standardize, leading to asymmetrical support structures, unbalanced load-bearing capacity of the ribs, and a tendency for fatigue damage. In severe cases, this can cause structural instability. Moreover, the poor consistency of component processing makes standardized production impossible. Secondly, the process suffers from low construction efficiency due to high levels of manual intervention and fragmented processes. The alignment, fine-tuning, and spot welding of the base plate and ribs are time-consuming, far exceeding actual welding time. The poor stability and intermittent nature of manual welding significantly lengthens the production cycle, making it unsuitable for batch processing. Finally, the process results in inconsistent forming quality and high construction costs. Positioning deviations lead to uneven gaps in the fit of components, making welding prone to defects such as incomplete penetration, slag inclusions, and burn-through. Uneven heat dissipation can also cause component deformation, resulting in rough weld appearances and a large amount of subsequent grinding and rework. High rework rates not only waste steel and welding materials but also increase labor and on-site installation and adjustment costs. The high dependence on skilled workers further increases construction costs, resulting in poor overall economic benefits. Summary of the Invention

[0004] This invention provides a steel structure foundation welding device to improve welding positioning accuracy, reduce the degree of manual intervention, and improve welding quality and efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A steel structure foundation welding device includes a longitudinal seat disposed above a tilting material placement mechanism. Multiple lifting rib clamping mechanisms are spaced apart along the length of the longitudinal seat. A conveying material placement mechanism is disposed on one side of the tilting material placement mechanism. The conveying direction of the conveying material placement mechanism is the same as the length direction of the longitudinal seat. Multiple steel structure rods are spaced apart along the conveying direction on the conveying material placement mechanism, with one end of each steel structure rod close to the tilting material placement mechanism. Welding robots are disposed between the tilting material placement mechanism and the conveying material placement mechanism and at each steel structure rod. Each welding robot is mounted on the longitudinal seat.

[0006] A further technical solution is that the flip-type material placement mechanism includes multiple substrate positioning seats that are rotatably connected to the assembly box at intervals along the length direction of the longitudinal seat. Adjacent substrate positioning seats are connected by a transmission assembly. A first motor is installed at the bottom of the assembly box. The first motor drives each substrate positioning seat to rotate via the transmission assembly. First support seats are rotatably mounted on both sides of the assembly box. A flip-drive assembly is installed between one of the first support seats and the assembly box. An ejection assembly is installed at the bottom of the assembly box and at a position corresponding to each substrate positioning seat. The upper end of the ejection assembly can movably eject the corresponding substrate positioning seat.

[0007] A further technical solution is that the substrate positioning seat includes a vertical sleeve that is rotatably connected to the assembly box and extends out of the assembly box at its upper end. The base plate to be welded is placed on the upper end of the vertical sleeve. Multiple connecting ears are arranged at intervals along the circumference on the outer circumferential surface of the vertical sleeve. Each of the connecting ears has a strip-shaped hole that extends radially outward along the vertical sleeve. A positioning bolt is installed in the strip-shaped hole. Each of the positioning bolts extends vertically into the connecting hole on the base plate.

[0008] A further technical solution is that a connecting sleeve is rotatably connected to the lower part of the vertical sleeve, and a lower end cover is detachably connected to the lower end of the vertical sleeve. The connecting sleeve and the lower end cover are rotatably connected. An air guide cavity is formed between the lower end cover, the connecting sleeve and the vertical sleeve. An air guide tube communicating with the air guide cavity is connected to the connecting sleeve. Multiple air guide channels are evenly opened along the circumference of the upper end of the vertical sleeve, and each air guide channel communicates with the air guide cavity vertically.

[0009] A further technical solution is that the ejection assembly includes a first cylinder installed at the lower end of the assembly box, the cylinder rod of the first cylinder extending vertically into the corresponding vertical sleeve, and an ejector head installed at the end of the cylinder rod of the first cylinder; the transmission assembly includes a first gear coaxially mounted outside the vertical sleeve, a second gear disposed between two adjacent vertical sleeves, the second gear meshing with two adjacent first gears, and the second gear being rotatably connected to the assembly base via a vertical shaft.

[0010] A further technical solution is that the flipping drive assembly includes a second motor mounted on a first support base, connecting shafts fixed at both ends of the assembly box, each connecting shaft being rotatably connected to the corresponding first support base, and synchronous pulleys mounted on the output shaft of the second motor and the corresponding connecting shaft, with the two synchronous pulleys connected by a synchronous belt drive.

[0011] A further technical solution is that the lifting rib clamping mechanism includes a second cylinder whose upper end is connected to the longitudinal seat. The cylinder rod of the second cylinder is rotatably connected to the adapter seat via an adapter sleeve. The adapter seat is connected to the adjustable clamping assembly. Multiple reinforcing ribs are clamped on the adjustable clamping assembly at circumferential intervals along the adjustable clamping assembly.

[0012] A further technical solution is that the adjustable clamping assembly includes a vertical telescopic member installed at the lower end of the adapter, a first base and a second base are fixed at the upper and lower ends of the vertical telescopic member respectively, a plurality of first hinge rods are evenly hinged on the first base along its circumference, a second hinge rod is hinged on the second base at a position corresponding to the first hinge rod, and the first hinge rod and the second hinge rod are hinged to each other, and a pneumatic gripper is assembled at the hinge point of the first hinge rod and the second hinge rod.

[0013] A further technical solution is that the conveying material placement mechanism includes two conveying units spaced apart along the length of the steel structure rod, the two conveying units being connected to a drive unit located between them, and the two ends of the steel structure rod being placed on the two conveying units respectively.

[0014] A further technical solution is that the conveying unit includes two conveying wheels spaced apart along the length direction of the longitudinal seat, the two conveying wheels are connected by a conveyor belt, and multiple limiting seats are installed at intervals along the extension direction of the conveyor belt, with steel structure rods placed on the limiting seats; the driving unit includes two transverse shafts, each transverse shaft is coaxially connected to the conveying wheels on the same side of the two conveying units, and each transverse shaft is rotatably connected to a second support seat at both ends, and a drive wheel is respectively mounted on one transverse shaft and the output shaft of a third motor, and the two drive wheels are connected by a drive belt.

[0015] The present invention, by employing the above-described structure, achieves the following technological advancements compared to existing technologies: In this invention, the welding of the base plate and multiple reinforcing ribs is first completed with the tilting material placement mechanism in the untilted state. After the base plate and reinforcing ribs are welded, the tilting material placement mechanism is rotated 90° so that the base plate with the reinforcing ribs faces the end of the steel structure rod. Then, the base plate is pushed out and assembled onto the end of the steel structure rod. Due to the constraints of the base plate and multiple reinforcing ribs, the installation position of the steel structure rod and the steel structure base is ensured to remain unchanged. After the positioning and assembly are completed, the welding operations of the base plate and the steel structure rod, and the reinforcing ribs and the steel structure rod are then performed. This invention, through the coordinated layout of the tilting material placement mechanism, the longitudinal seat, the lifting rib clamping mechanism, the conveying material placement mechanism, and the welding robot, can effectively improve the industry pain points of traditional welding, such as poor manual positioning accuracy, excessive manual intervention, unstable welding quality, and low production efficiency.

[0016] This invention features multiple sets of lifting rib clamping mechanisms arranged at intervals on a longitudinal seat. These mechanisms automatically clamp the reinforcing ribs, mechanically constraining their height, circumferential angle, spacing, and verticality. This eliminates the need for manual placement and avoids asymmetrical rib arrangement. A flipping material placement mechanism positions the base plate (i.e., the foot plate), while a conveying material placement mechanism arranges multiple steel structural members in an orderly manner. The ends of the steel structural members are positioned close to the flipping material placement mechanism, ensuring precise alignment of the steel structural members, the base plate, and the reinforcing ribs. This effectively suppresses issues such as eccentricity and horizontal deviation between the base plate and the steel structural members, ensuring uniform dimensions for all steel structural foot components and avoiding stress concentration and imbalance caused by assembly deviations.

[0017] This invention integrates rib clamping and positioning, steel structure rod material conveying and positioning, and base plate positioning and assembly functions. A lifting rib clamping mechanism completes the clamping and positioning of the reinforcing ribs, while a conveying material placement mechanism completes the conveying and positioning of the steel structure rod material. This reduces manual handling, manual alignment, repeated fine-tuning, and manual spot welding pre-fixing processes, thus reducing reliance on skilled workers. Each steel structure rod workstation is equipped with an independent welding robot, and all welding robots are uniformly mounted on a longitudinal seat, ensuring consistent installation standards and high welding motion positioning accuracy. Workpieces are directly welded after precise positioning by the mechanism, resulting in uniform and controllable joint gaps between components. This reduces welding defects such as incomplete penetration, slag inclusions, and burn-through, avoids the instability problems of manual welding operations, ensures stable weld quality, and reduces the workload of subsequent grinding and rework.

[0018] This invention employs a multi-station parallel layout. Multiple sets of lifting rib clamping mechanisms are arranged along the length of the longitudinal seat. A conveyor-type material placement mechanism simultaneously carries multiple steel structural members. Each station is equipped with a dedicated welding robot, enabling simultaneous assembly and welding of multiple steel structural bases. This changes the traditional fragmented processing mode, eliminating the need for extensive manual labor in assembly and positioning. The conveyor-type material placement mechanism allows for continuous workpiece feeding, with all mechanisms working in tandem to shorten the overall processing cycle, making it suitable for mass industrial production of steel structural bases. Furthermore, the equipment has a compact layout and good mechanism coordination. The flipping material placement mechanism and the conveyor-type material placement mechanism are located on opposite sides, while the rib clamping mechanism and welding robot are integrated on the upper longitudinal seat. The entire system has a unified installation standard, and the spatial layout matches the base assembly process, facilitating coordinated action of all mechanisms and resulting in a highly integrated machine.

[0019] In summary, this invention achieves integrated operation of positioning, assembly, and welding of steel structure foundations, which can effectively improve the positioning accuracy of welding, reduce the degree of manual intervention, and improve welding quality and production efficiency.

Detailed Implementation

[0023] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0024] This invention discloses a steel structure foundation welding device, such as... Figures 1-16 As shown, the system includes a longitudinal seat 200 positioned above a tilting material placement mechanism 100. Multiple lifting rib clamping mechanisms 300 are spaced apart along the length of the longitudinal seat 200. A conveying material placement mechanism 600 is positioned on one side of the tilting material placement mechanism 100, with the conveying direction of the conveying material placement mechanism 600 being the same as the length direction of the longitudinal seat 200. Multiple steel structural rods 700 are spaced apart along the conveying direction on the conveying material placement mechanism 600, with one end of each steel structural rod 700 close to the tilting material placement mechanism 100. Welding robots 400 are positioned between the tilting material placement mechanism 100 and the conveying material placement mechanism 600, and are respectively located at each steel structural rod 700. Each welding robot 400 is mounted on the longitudinal seat 200.

[0025] The working principle and advantages of this invention are as follows: During operation, the base plate 501 and multiple reinforcing ribs 503 are first welded together with the flipping material placement mechanism 100 in the unflipped state. After the base plate 501 and reinforcing ribs 503 are welded together, the flipping material placement mechanism 100 is controlled to flip 90° so that the base plate 501 with the reinforcing ribs 503 is facing the end of the steel structure rod 700. Then, the base plate 501 is pushed out and assembled onto the end of the steel structure rod 700. Due to the constraints of the base plate 501 and multiple reinforcing ribs 503, the installation position of the steel structure rod 700 and the steel structure base 500 will not be offset. After the positioning assembly is completed, the welding operations of the base plate 501 and the steel structure rod 700, and the reinforcing ribs 503 and the steel structure rod 700 are then performed. The present invention, through the coordinated layout of the flip-type material placement mechanism 100, the longitudinal seat 200, the lifting rib clamping mechanism 300, the conveying material placement mechanism 600 and the welding robot 400, can effectively improve the industry pain points of traditional welding, such as poor manual positioning accuracy, excessive manual intervention, unstable welding quality and low production efficiency.

[0026] This invention features multiple sets of lifting rib clamping mechanisms 300 spaced apart on the longitudinal seat 200. These mechanisms automatically clamp the reinforcing ribs 503, mechanically constraining the height, circumferential angle, spacing, and verticality of the ribs. This eliminates the need for manual placement and avoids asymmetrical rib arrangement. A flipping material placement mechanism 100 positions the base plate 501, while a conveying material placement mechanism 600 arranges multiple steel structural members 700 in an orderly manner. The ends of the steel structural members 700 are close to the flipping material placement mechanism 100, achieving precise alignment of the steel structural members 700, the base plate 501, and the reinforcing ribs 503. This effectively suppresses problems such as eccentricity and horizontal deviation between the base plate 501 and the steel structural members 700, ensuring uniform dimensions for each steel structural base 500 component and avoiding stress concentration and imbalance caused by assembly deviations.

[0027] This invention integrates rib clamping and positioning, steel structure rod 700 conveying and positioning, and base plate 501 positioning and assembly functions. The lifting rib clamping mechanism 300 clamps and positions the reinforcing rib 503, while the conveying material placement mechanism 600 conveys and positions the steel structure rod 700. This reduces manual handling, manual alignment, repeated fine-tuning, and manual spot welding pre-fixing processes, lowering reliance on skilled workers. Each steel structure rod 700 station is equipped with an independent welding robot 400, and all welding robots 400 are uniformly mounted on the longitudinal seat 200, ensuring consistent installation standards and high welding motion positioning accuracy. Workpieces are directly welded after precise positioning by the mechanism, resulting in uniform and controllable joint gaps between components. This reduces welding defects such as incomplete penetration, slag inclusions, and burn-through, avoiding the instability of manual welding operations. The weld formation quality is stable, reducing the workload of subsequent grinding and rework.

[0028] This invention adopts a multi-station parallel layout. Multiple sets of lifting rib clamping mechanisms 300 are arranged along the length of the longitudinal seat 200. The conveying material placement mechanism 600 simultaneously carries multiple steel structure rods 700. Each station is equipped with a dedicated welding robot 400, enabling simultaneous assembly and welding of multiple sets of steel structure bases 500. This changes the traditional fragmented processing mode, eliminating the need for extensive manual labor in assembly and positioning. The conveying material placement mechanism 600 allows for continuous workpiece feeding, and the coordinated operation of all mechanisms shortens the overall processing cycle, making it suitable for mass industrial production of steel structure bases 500. Simultaneously, the equipment layout is compact, with good mechanism coordination. The flipping material placement mechanism 100 and the conveying material placement mechanism 600 are positioned on opposite sides, while the rib clamping mechanism and welding robot 400 are integrated on the upper longitudinal seat 200. The entire equipment has a unified installation standard, and the spatial layout matches the base assembly process, facilitating coordinated action of all mechanisms and resulting in strong overall machine integrity.

[0029] In summary, this invention enables the integrated operation of positioning, assembly, and welding of the steel structure base 500, which can effectively improve the positioning accuracy of welding, reduce the degree of manual intervention, and improve welding quality and production efficiency.

[0030] As a preferred embodiment of the present invention, such as Figures 6-9 As shown, the flip-type material placement mechanism 100 includes an assembly box 101, which is composed of two end plates 1011 and two side plates 1012. Multiple substrate positioning seats 102 are rotatably connected to the assembly box 101 along the length of the longitudinal seat 200. Adjacent substrate positioning seats 102 are connected by a transmission assembly. A first motor 109 is installed at the bottom of the assembly box 101. The first motor 109 drives each substrate positioning seat 102 to rotate via the transmission assembly, thereby causing the base plate 501 placed on the substrate positioning seat 102 to rotate, realizing the welding robot 400's weld-free operation. First support seats 104 are rotatably mounted on both sides of the assembly box 101, and a flip-drive assembly 105 is installed between one of the first support seats 104 and the assembly box 101. At the bottom of the assembly box 101 and corresponding to each substrate positioning seat 102, an ejector assembly 103 is installed. The upper end of the ejector assembly 103 can eject the corresponding substrate positioning seat 102. When the flip-type material placement mechanism 100 rotates the bottom plate 501 carrying the welded reinforcing rib 503 by 90°, the ejector assembly 103 is controlled to move, so that it ejects the bottom plate 501 and assembles it at the end of the steel structure rod 700.

[0031] In this embodiment, the assembly box 101 is assembled from two end plates 1011 and two side plates 1012. The assembled box structure facilitates the arrangement and installation of the transmission components and ejection components 103 inside the assembly box 101, and also facilitates the inspection, disassembly and maintenance of the internal parts of the box in the later stage, reducing the difficulty of equipment processing and manufacturing as well as later maintenance. Multiple substrate positioning seats 102 are rotatably connected to the assembly box 101 along the length of the longitudinal seat 200. Adjacent substrate positioning seats 102 are driven together by a transmission assembly. The first motor 109 at the bottom of the assembly box 101 can drive each substrate positioning seat 102 to rotate through the transmission assembly, thereby driving the base plate 501 placed on the substrate positioning seat 102 to rotate synchronously. Relying on the workpiece itself to rotate and reposition, the welding robot 400 can perform welding operations without dead angles without the need for large-scale, multi-angle position adjustments. This eliminates welding blind spots and ensures that all welds on the base plate 501 can be fully welded. At the same time, multiple sets of substrate positioning seats 102 can rotate synchronously, which can meet the batch production needs of multi-station synchronous processing. The assembly box 101 is rotatably mounted with first support seats 104 on both sides, and a flipping drive assembly 105 is mounted between one of the first support seats 104 and the assembly box 101. The flipping drive assembly 105 can drive the assembly box 101 to flip 90° relative to the first support seat 104, so that the base plate 501 carrying the welded reinforcing ribs 503 can complete the posture change, so that the base plate 501 faces the end of the steel structure rod 700. There is no need for manual transfer and flipping of the workpiece, avoiding the positioning deviation caused by secondary transfer of the workpiece.

[0032] The bottom of the assembly box 101 is equipped with an ejector assembly 103 corresponding to each of the substrate positioning seats 102. The upper end of the ejector assembly 103 can perform a telescopic ejection action. After the flip-type material placement mechanism 100 carries the base plate 501 with welded reinforcing ribs 503 and flips it 90° to the correct position, the corresponding ejector assembly 103 can be controlled to eject the base plate 501 and assemble it at the end of the steel structure rod 700. Each substrate positioning seat 102 is equipped with an independent ejector assembly 103, which supports multi-station operation. The assembly process can be performed step-by-step and also supports independent operation at a single station, offering high operational flexibility. The base plate 501, together with the already welded reinforcing ribs 503, is directly ejected and assembled as a whole. The formed base plate 501 and reinforcing ribs 503 provide limiting constraints on the ends of the steel structure rods 700, effectively preventing positional displacement of the base plate 501 relative to the steel structure rods 700 during the assembly process. This provides a reliable assembly positioning basis for the subsequent welding processes between the base plate 501, reinforcing ribs 503, and steel structure rods 700.

[0033] As a preferred embodiment of the present invention, such as Figure 10As shown, the substrate positioning base 102 includes a vertical sleeve 1021, which is rotatably connected to the assembly box 101, and the upper end of the vertical sleeve 1021 extends out of the assembly box 101. The base plate 501 to be welded is placed on the upper end of the vertical sleeve 1021. A plurality of connecting ears 1022 are constructed circumferentially on the outer circumferential surface of the vertical sleeve 1021. Each connecting ear 1022 has a strip-shaped hole 1023 extending radially outward along the vertical sleeve 1021. A positioning bolt 1024 is installed in the strip-shaped hole 1023. A fastening nut 1025 is threaded onto the positioning bolt 1024 for fastening the positioning bolt 1024 to the connecting ear 1022. Each positioning bolt 1024 extends vertically into the connecting hole 502 on the base plate 501.

[0034] In this embodiment, the substrate positioning seat 102 is provided with a vertical sleeve 1021. The upper end of the vertical sleeve 1021 provides a stable support position for the base plate 501 to be welded. The vertical sleeve 1021 can rotate with the transmission component, driving the base plate 501 placed on it to rotate synchronously, thereby cooperating with the welding robot 400 to achieve all-round welding operation. The structure of the upper end of the vertical sleeve 1021 extending out of the assembly box 101 makes it easy for the feeding mechanism or operator to place the base plate 501 to be welded in place, making the workpiece feeding operation convenient. Multiple connecting ears 1022 are arranged at intervals along the circumference on the outer circumferential surface of the vertical sleeve 1021. The connecting ears 1022 are provided with strip-shaped holes 1023 extending radially outward along the vertical sleeve 1021. The strip-shaped holes 1023 allow the positioning bolts 1024 to have radial adjustment margin, which can be adapted to the base plate 501 with different arrangement specifications of connecting holes 502, and is compatible with the processing and production of steel structure feet 500 of various specifications, thus expanding the application range of the equipment. The multiple connecting ears 1022 arranged at intervals along the circumference can form multi-directional constraint points, so that the base plate 501 is subjected to uniform force when positioned, avoiding local stress concentration. The positioning bolt 1024, installed in the strip hole 1023, extends vertically into the connecting hole 502 on the base plate 501, thereby limiting and fixing the base plate 501, effectively restricting the relative displacement between the base plate 501 and the vertical sleeve 1021, preventing the base plate 501 from shifting or rotating during the entire welding process of the base plate 501 and the reinforcing rib 503, and ensuring the positioning accuracy of the welding operation.

[0035] The connecting hole 502 on the base plate 501 has a dual function. During the welding process, the positioning bolt 1024 can be inserted to complete the tooling positioning of the base plate 501, eliminating the need to open a special process positioning hole on the base plate 501 and saving the extra hole opening process. At the same time, the connecting hole 502 can be directly used as an anchoring hole for the subsequent use of the finished steel structure foot 500, realizing two uses in one hole, simplifying the processing process of the base plate 501 component, reducing the component processing cost, and avoiding structural damage to the base plate 501 base caused by opening an additional process hole, thus ensuring the structural integrity and load-bearing performance of the finished steel structure foot 500.

[0036] As a preferred embodiment of the present invention, such as Figure 11 , Figure 12 As shown, a connecting sleeve 1027 is rotatably connected to the lower part of the vertical sleeve 1021. A lower end cover 1028 is detachably connected to the lower end of the vertical sleeve 1021. The connecting sleeve 1027 and the lower end cover 1028 are rotatably connected. An air guide cavity 1029 is formed between the lower end cover 1028, the connecting sleeve 1027 and the vertical sleeve 1021. An air guide pipe 110 communicating with the air guide cavity 1029 is connected to the connecting sleeve 1027. The air guide pipe 110 is connected to the assembly box 101. Multiple air guide channels 1026 are evenly opened along the circumference of the upper end of the vertical sleeve 1021. Each air guide channel 1026 is vertically connected to the air guide cavity 1029.

[0037] In this embodiment, the vertical sleeve 1021 and the connecting sleeve 1027 are rotatably connected. The lower end cover 1028, which is coaxially and detachably connected to the lower end of the vertical sleeve 1021, is rotatably engaged. This structure allows the vertical sleeve 1021 to rotate synchronously with the base plate 501, while the connecting sleeve 1027 remains stationary. The air guide pipe 110 connected to the connecting sleeve 1027 will not twist or become entangled with the vertical sleeve 1021, effectively preventing the air guide pipe 110 from bending, breaking, or leaking, ensuring the continuous and stable operation of the negative pressure air circuit. The lower end cover 1028 of the vertical sleeve 1021 adopts a coaxial and detachable assembly form, which facilitates the assembly of internal components of the air guide chamber 1029 and allows for disassembly after a period of equipment use. This facilitates the cleaning of accumulated welding slag, dust, and impurities inside the air guide chamber 1029, reducing the difficulty of equipment inspection and maintenance.

[0038] The lower end cover 1028, connecting sleeve 1027, and vertical sleeve 1021 together form an air guiding cavity 1029. The air guiding pipe 110 is connected to the air guiding cavity 1029. Multiple air guiding channels 1026 are evenly opened along the circumference of the upper end of the vertical sleeve 1021. Each air guiding channel 1026 is connected to the air guiding cavity 1029, thus constructing a complete negative pressure adsorption air path. When the base plate 501 to be welded is placed on the upper end of the vertical sleeve 1021, suction is performed through the air guiding pipe 110, and the upper end of the air guiding channel 1026 generates negative pressure suction, adsorbing and pressing the base plate 501 tightly against the upper end face of the vertical sleeve 1021. The negative pressure adsorption structure and the mechanical limit formed by the positioning bolt 1024 create a dual positioning constraint, which can eliminate the potential for minor displacement caused by the assembly gap between the positioning bolt 1024 and the connection hole 502 of the base plate 501. The circumferentially evenly arranged air guide channels 1026 can evenly distribute the adsorption force on the lower end face of the base plate 501, preventing the base plate 501 from warping due to local stress. During the entire welding process of the base plate 501 rotating with the vertical sleeve 1021, the negative pressure can continue to take effect, which can suppress the warping of the base plate 501 and the vibration of the workpiece caused by the high temperature of welding, further enhance the positioning effect of the base plate 501, avoid the base plate 501 from having a slight offset, improve the positioning accuracy of the welding operation, and ensure the processing consistency of each steel structure foot 500 product.

[0039] As a preferred embodiment of the present invention, such as Figure 9 , Figure 10 As shown, the ejector assembly 103 includes a first cylinder 1031 mounted on the lower end of the assembly box 101. The cylinder rod of the first cylinder 1031 extends vertically into the corresponding vertical sleeve 1021, and an ejector head 1032 is installed at the end of the cylinder rod of the first cylinder 1031. The transmission assembly includes a first gear 106 coaxially mounted on the outside of the vertical sleeve 1021. A second gear 108 is provided between two adjacent vertical sleeves 1021. The second gear 108 meshes with two adjacent first gears 106, and the second gear 108 is rotatably connected to the assembly base through a vertical shaft 107 coaxially connected to it. The output shaft of the first motor 109 is coaxially connected to one of the vertical shafts 107.

[0040] In this embodiment, the ejector assembly 103 installs the first cylinder 1031 at the lower end of the assembly box 101. The first cylinder 1031 is arranged at the lower part of the assembly box 101 and will not occupy the welding operation space above the assembly box 101. This avoids motion interference with the upper execution components such as the welding robot 400 and the lifting rib clamping mechanism 300. The cylinder rod of the first cylinder 1031 extends vertically into the corresponding vertical sleeve 1021. The ejector head 1032 is installed at the end of the cylinder rod. The ejector head 1032 performs telescopic movements inside the vertical sleeve 1021. When the flipping material placement mechanism 100 flips into place, the ejector head 1032 can be driven by the first cylinder 1031 to extend and smoothly eject the bottom plate 501, which is placed on the upper end of the vertical sleeve 1021 and has been welded with the reinforcing rib 503, thus completing the assembly operation of the bottom plate 501 to the end of the steel structure rod 700.

[0041] In this embodiment, the transmission assembly adopts a gear meshing transmission form. The first motor 109 outputs power to drive the corresponding vertical shaft 107 and the second gear 108 to rotate. The power is transmitted sequentially to the first gear 106 on the outside of each vertical sleeve 1021 through the meshing transmission of the second gear 108, thereby driving all the vertical sleeves 1021 to achieve synchronous rotation. This gear transmission structure has high transmission accuracy and good multi-station rotation synchronization, which can ensure that the rotation speed and rotation angle of all base plate positioning seats 102 are consistent, and is suitable for the batch processing requirements of multi-station synchronous displacement welding. The entire gear transmission assembly is arranged inside the assembly box 101. The assembly box 101 can protect the gear pair, reduce welding spatter, welding slag, and dust falling into the gear meshing position, reduce the probability of gear jamming and wear failure, and extend the service life of transmission components.

[0042] As a preferred embodiment of the present invention, such as Figure 8 As shown, the flip drive assembly 105 includes a second motor 1052 mounted on a first support base 104. Connecting shafts 1051 are fixed at both ends of the assembly box 101. Each connecting shaft 1051 is rotatably connected to the corresponding first support base 104. Synchronous pulleys 1053 are mounted on the output shaft of the second motor 1052 and on the corresponding connecting shafts 1051. The two synchronous pulleys 1053 are connected by a synchronous belt 1054.

[0043] In this embodiment, the flipping drive assembly 105 mounts the second motor 1052 on the first support base 104. The second motor 1052 is fixedly mounted on the stationary first support base 104 and will not flip or swing with the assembly box 101. Connecting shafts 1051 are fixed to both ends of the assembly box 101, and each connecting shaft 1051 is rotatably connected to the corresponding first support base 104. The assembly box 101 adopts a double-end rotating shaft support structure. The load during the flipping operation is borne jointly by the first support bases 104 on both sides, resulting in balanced overall force distribution. It can withstand the total load of multiple sets of base plate positioning seats 102 and the workpiece on the base plate 501. The flipping process is smooth, effectively suppressing mechanism shaking and vibration, and ensuring the posture accuracy of the assembly box 101 after flipping. Synchronous pulleys 1053 are respectively mounted on the output shaft of the second motor 1052 and the corresponding connecting shaft 1051. The two synchronous pulleys 1053 are connected by a synchronous belt 1054. The synchronous belt 1054 is a meshing transmission with a constant transmission ratio, so there will be no slippage or loss of rotation. It can precisely control the flipping angle of the assembly box 101, ensuring that the assembly box 101 can reliably and accurately complete a 90° flip, so that the bottom plate 501 with welded reinforcing ribs 503 is accurately aligned with the end of the steel structure rod 700, providing an accurate posture basis for the subsequent ejection assembly process.

[0044] As a preferred embodiment of the present invention, such as Figure 13 , Figure 14 As shown, the lifting rib clamping mechanism 300 includes a second cylinder 301 whose upper end is connected to the longitudinal seat 200. The cylinder rod of the second cylinder 301 is rotatably connected to the adapter seat 313 through the adapter sleeve 314. The adapter seat 313 is connected to the adjustable clamping assembly. Multiple reinforcing ribs 503 are clamped on the adjustable clamping assembly at circumferential intervals along the adjustable clamping assembly. The adjustable clamping assembly includes a vertical telescopic member installed at the lower end of the adapter 313. A first seat 304 and a second seat 305 are fixed at the upper and lower ends of the vertical telescopic member, respectively. Multiple first hinge rods 306 are evenly hinged to the first seat 304 along its circumference. A second hinge rod 307 is hinged to the second seat 305 at a position corresponding to the first hinge rods 306. The first hinge rods 306 and the second hinge rods 307 are hinged to each other. A pneumatic gripper 309 is assembled at the hinge point between the first hinge rods 306 and the second hinge rods 307.

[0045] In this embodiment, the upper end of the second cylinder 301 of the lifting rib clamping mechanism 300 is connected to the longitudinal seat 200. The second cylinder 301 serves as the power source to drive the cylinder rod to perform vertical extension and retraction, thereby driving the entire adjustable clamping assembly to lift and lower. This achieves the lowering and positioning of the reinforcing rib 503 and its lifting and resetting after welding, automating the feeding and positioning of the reinforcing rib 503 and replacing manual handling of the reinforcing rib 503, reducing manual operation. The cylinder rod of the second cylinder 301 is rotatably connected to the adapter seat 313 through the adapter sleeve 314, giving the adapter seat 313 and the connected adjustable clamping assembly a degree of rotational freedom. When the lower substrate positioning seat 102 drives the base plate 501 to rotate for welding, the multiple clamped reinforcing ribs 503 can rotate synchronously with the base plate 501, eliminating rotational interference between the reinforcing ribs 503 and the base plate 501, and ensuring a stable fit between the reinforcing ribs 503 and the base plate 501 throughout the welding process.

[0046] An adjustable clamping assembly is installed at the lower end of the adapter 313. This assembly drives the first seat 304 and the second seat 305 at its upper and lower ends to move vertically relative to each other through a vertical telescopic component. The first seat 304 is circumferentially hinged with multiple first hinge rods 306, and the second seat 305 is correspondingly hinged with second hinge rods 307. The first hinge rods 306 and the second hinge rods 307 are hinged to each other to form a scissor-type linkage structure. A pneumatic gripper 309 is installed at the hinge position. When the vertical telescopic component changes the relative distance between the first seat 304 and the second seat 305, all the scissor linkage structures swing synchronously, driving all the pneumatic grippers 309 to open or close radially in unison. This uniformly adjusts the circumferential distribution radius of all the pneumatic grippers 309. Multiple pneumatic grippers 309 clamp multiple reinforcing ribs 503 at intervals along the circumference, ensuring that the reinforcing ribs 503 are arranged at uniform angles and with consistent spacing. This not only allows for the simultaneous clamping and positioning of multiple reinforcing ribs 503, but also enables the processing of steel structure feet 500 of different specifications and sizes, improving the equipment's versatility.

[0047] The vertical telescopic component offers multiple implementation options. It can be equipped with a pneumatic cylinder or an electric cylinder, relying on a power element to automatically adjust the relative position of the base and realize the automated change of the gripper's clamping radius, adapting to fully automated continuous batch production scenarios. Alternatively, it can adopt a mechanical combination structure of interlocking connecting pipes 302 and connecting rods 303. After adjusting the overlap length of the interlocking connecting pipes 302 and connecting rods 303, it can be locked and positioned by fixing bolts. No additional drive air source and electrical control are required. The size is fixed by mechanical locking, which is suitable for processing conditions with small batches and frequent changes in workpiece specifications.

[0048] As a preferred embodiment of the present invention, such as Figure 14As shown, the first hinge rod 306 and the second hinge rod 307 are hinged together by the mounting rod 308. Fixing sleeves 311 are respectively fitted at both ends of the mounting rod 308. The fixing sleeves 311 are fixed to the mounting rod 308 by locking bolts 312. A connecting plate 310 is fixed on each fixing sleeve 311. The connecting plate 310 is detachably connected to the pneumatic gripper 309.

[0049] In this embodiment, the first hinge rod 306 and the second hinge rod 307 are hinged together by the mounting rod 308. The rotation fulcrum of the two sets of hinge rods is integrated on the mounting rod 308 component, so that the rotation pair structure of the scissor linkage mechanism is concentrated. This ensures that the swing opening and closing action of the first hinge rod 306 and the second hinge rod 307 is smooth, ensures the consistency of the radial opening and closing action of all pneumatic grippers 309, and ensures the synchronous adjustment accuracy of the clamping position of multiple reinforcing ribs 503. Fixing sleeves 311 are fitted at both ends of the mounting rod 308. The fixing sleeves 311 are locked to the mounting rod 308 by locking bolts 312. Loosening the locking bolts 312 allows adjustment of the mounting position of the fixing sleeves 311 in the axial direction of the mounting rod 308. After locking, the position is locked. The working span between the two fixing sleeves 311 can be flexibly adjusted according to the width of the reinforcing rib 503 to be processed, adapting to the installation requirements of pneumatic grippers 309 of different shapes and specifications, thus broadening the applicability of the mechanism. The fastening structure of the locking bolts 312 is easy to disassemble and assemble, facilitating on-site assembly and debugging. Each fixing sleeve 311 is fixed with a connecting plate 310, and the connecting plate 310 is detachably connected to the pneumatic gripper 309. The pneumatic gripper 309 is subjected to welding conditions for extended periods, making it susceptible to wear and tear from weld spatter and high-temperature baking. This detachable connection structure allows for the individual removal and replacement of a faulty pneumatic gripper 309 without disassembling the entire scissor lift mechanism, reducing equipment maintenance disassembly and assembly steps and shortening equipment downtime. Furthermore, depending on the thickness and cross-sectional profile of the reinforcing rib 503, the appropriate pneumatic gripper 309 can be directly replaced to fit the clamping surface, enabling reliable clamping of various specifications of reinforcing ribs 503 and further enhancing the versatility of the adjustable clamping assembly.

[0050] As a preferred embodiment of the present invention, such as Figure 15 , Figure 16As shown, the conveying material placement mechanism 600 includes two conveying units 601 spaced apart along the length of the steel structure rod 700. These two conveying units 601 are connected to a drive unit located between them. Both ends of the steel structure rod 700 are placed on the two conveying units 601 respectively. Each conveying unit 601 includes two conveying wheels 6012 spaced apart along the length of the longitudinal seat 200. These two conveying wheels 6012 are connected via a conveyor belt 6013. Multiple limiting seats 6014 are spaced apart along the extension direction of the conveyor belt 6013, and the steel structure rod 700 is placed on the limiting seats 6014. The drive unit includes two transverse shafts 602. Each transverse shaft 602 is coaxially connected to two conveying wheels 6012 located on the same side of the two conveying units 601. Each end of each transverse shaft 602 is rotatably connected to a second support base 6011. A transmission wheel 604 is mounted on one of the transverse shafts 602 and the output shaft of the third motor 603. The two transmission wheels 604 are connected by a transmission belt 605.

[0051] In this embodiment, the conveying material placement mechanism 600 adopts a structure in which two conveying units 601 are arranged at intervals along the length of the steel structure rod 700. The two ends of the steel structure rod 700 are respectively placed on the two conveying units 601, forming a double-point support. This allows for end-to-end bearing of long steel structure rods 700, avoiding bending deformation caused by single-point support of long rods, ensuring that the steel structure rod 700 is placed in a straight position, and providing a reliable foundation for the subsequent precise docking and assembly of the ends of the steel structure rod 700 with the base plate 501. The two sets of conveying units 601 are connected by a drive unit located between them, ensuring that the two sets of conveying units 601 can operate in coordination.

[0052] The conveying unit 601 consists of two conveying wheels 6012 and a matching conveyor belt 6013. Multiple limiting seats 6014 are installed at intervals along the extension direction of the conveyor belt 6013. The steel structure rods 700 are placed on the limiting seats 6014. The limiting seats 6014 can form a lateral limiting constraint on the steel structure rods 700 to prevent the rods from rolling or shifting laterally during the conveying process. The limiting seats 6014 arranged at intervals on the conveyor belt 6013 can maintain a fixed station spacing between multiple steel structure rods 700. They can correspond one-to-one with the station positions of each base plate positioning seat 102 on the flip-type material placement mechanism 100, ensuring that each steel structure rod 700 is accurately matched with a set of base plate 501 components to be assembled, and realizing the orderly and isolated feeding of multiple rods. In the drive unit, a transverse shaft 602 and the output shaft of the third motor 603 are respectively equipped with transmission wheels 604. The two transmission wheels 604 transmit power through a transmission belt 605. Only a single third motor 603 is needed to drive the entire conveying mechanism, reducing the number of motors, simplifying the overall power and electrical control system, and reducing equipment manufacturing costs.

[0053] The complete set of conveying and material placement mechanism 600 can automatically convey and position multiple steel structure rods 700, accurately conveying the steel structure rods 700 to the assembly station close to the flipping material placement mechanism 100. It works in conjunction with the flipping material placement mechanism 100 and the welding robot 400 station to reduce manual handling and material loading operations, and adapt to the use needs of multi-station batch welding processing of equipment.
