Description

Technical Field

[0001] This invention relates to the field of U-rib plate application technology, and more specifically to a novel automatic welding device for assembling U-rib web plates. Background Technology

[0002] With the rapid development of my country's economy and people's urgent need for a better life, domestic infrastructure construction is progressing at an increasingly rapid pace, with more and more high-rise buildings springing up, and their floor slab structures taking on various forms. When strict requirements are placed on floor clearance, construction technology, the economy of structural schemes, and construction period, and under conditions of large loads, traditional beam-slab structures and truss structures are difficult to meet the requirements of safety, economy, applicability, and advanced technology.

[0003] Existing floor slab types include beam slabs and flat slab structures, both of which use concrete as the main foundation material. Concrete itself is heavy and has a significant heat of hydration, which has a considerable impact on the floor structure. Under large loads, concrete structures are prone to fatigue, affecting their service life. For flat slabs, the height-to-span ratio is limited in actual projects, making it difficult to meet the requirements of large spans, large grid columns, and large bays.

[0004] Existing hollow honeycomb beams and hollow box girders offer good economic benefits, but their internal force distribution under load is complex, limiting their application to bridge structures. Existing truss beams and space frame beams, under load, rely on welded steel joints for contact points, resulting in large deformations and failing to fully utilize the tensile properties of steel. Furthermore, the fully welded connections of steel trusses and space frame beams make controlling welding deformation difficult. In contrast, the U-ribbed web prefabricated floor slab, a novel structure, utilizes a steel plate-concrete composite structure, fully leveraging the compressive properties of concrete and the tensile properties of steel. The U-ribbed web prefabricated floor slab structure employs fully prefabricated production. The method involves dividing the floor structure into lower ribs and upper ribs connected by U-ribs, both of which are prefabricated in the factory and then transported to the construction site for assembly. This can effectively improve construction efficiency and ensure project quality. However, currently, most U-rib plates are welded manually, one by one, with each U-rib, bottom plate, and end plate. This is inefficient, time-consuming, labor-intensive, and increases the workload of workers, especially for large spans. In addition, burrs generated during production still exist in some U-rib web plates during welding, which greatly affects the welding quality. Therefore, based on the shortcomings of existing technology, it is necessary to design a new type of automatic welding device for assembling U-rib web plates. Summary of the Invention

[0005] The purpose of this invention is to provide a novel automatic welding device for assembling U-rib web plates.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] Furthermore, the translation assembly includes a second motor, a second threaded rod, a movable frame, a first bearing, a crossbar, two side platforms, two first slide rails, and two carriers.

[0011] Furthermore, the sensing component includes a mounting frame, an industrial camera, a signal line, and two support bases. The two support bases are symmetrically and fixedly mounted on two corresponding side platforms. The bottom ends of the mounting frame are fixedly mounted on the two corresponding support bases. The industrial camera is fixedly mounted in an inverted position at the top center of the mounting frame. The controller is fixedly mounted on a corresponding side platform and located next to a support base. The two ends of the signal line are electrically connected to the industrial camera and the controller, respectively.

[0012] Furthermore, the lifting assembly includes a top frame, a mounting plate, a cylinder, a sliding plate, and two guide columns.

[0014] Furthermore, the drive assembly includes a third motor, a support plate, a rotating rod, a second shaft seat, and two bevel gear sets. The support plate is fixedly mounted on one end of the support column. The third motor is horizontally fixedly mounted on one side of the top of the support plate, and the output shaft of the third motor is fixedly connected to one end of the rotating rod via a coupling.

[0015] Furthermore, each set of sliding components includes an extension plate, a third threaded rod, a sliding block, and two second slide rails. The extension plate is fixedly disposed on one side of the support column, and both ends of the extension plate are symmetrically and fixedly provided with limiting plates.

The sliding block is limited and slidably disposed on the two second slide rails, and the sliding block is threadedly connected to the third threaded rod. The two welding torches are symmetrically and fixedly disposed on the corresponding two sliding blocks.

[0016] Furthermore, each set of buffer clamping components includes a movable plate, a limiting roller, and two return springs. One end of the movable plate is hinged to the bottom side of the bearing column, and the other end of the movable plate is provided with a rectangular hole. The limiting roller is rotatably disposed in the rectangular hole. One end of the two return springs is symmetrically welded to the movable plate, and the other end of the two return springs is welded to one end of the extension plate.

[0017] The beneficial effects of this invention are:

[0018] 1. First, the U-rib web is fed between two guide plates. The controller is turned on to turn on the first motor. The output shaft of the first motor drives the first rotating shaft to rotate through the coupling. The first rotating shaft drives the corresponding grinding wheel to rotate. At the same time, the first rotating shaft also drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the second rotating shaft to rotate, thereby driving the other grinding wheel to rotate. Then the two grinding wheels rotate synchronously. The two sides of the U-rib web are inserted into the grinding grooves of the two grinding wheels along the two guide plates for deburring. During the welding process, there are burrs on the bottom of the U-rib web. If they are not removed, they will directly affect the welding quality. The two grinding wheels effectively remove the burrs and also provide some translational force for the U-rib.

[0019] 2. As the U-rib plate moves forward, the industrial camera on the mounting frame performs image recognition. When one end of the U-rib plate moves to the bottom of one end of the clamping block, the industrial camera cannot detect the U-rib plate and transmits this signal to the controller via a signal line. The controller then shuts down the first motor. At this point, the adjustment handle is manually turned, which drives the first threaded rod to rotate. The first threaded rod drives the clamping block to move downwards, thus connecting and fixing one end of the U-rib plate. Next, the controller is operated to open the cylinder switch. The cylinder's output shaft, in conjunction with two guide pillars, drives the sliding plate to move downwards. The sliding plate then drives each bearing pillar to move downwards. The support column drives two limiting rollers at its bottom to fit against both sides of the U-rib plate. Four return springs play a role in buffering and fixing. Image recognition controls the start and stop of the first motor to ensure that the U-rib plate automatically disengages when it moves to one end of the clamping block, thus avoiding safety hazards and saving energy. Through the control of the cylinder, the upper limiting rollers of the movable plate at the bottom of each support column are in close contact with both sides of the U-rib plate. The setting of two return springs prevents the limiting rollers from being squeezed and deformed by the U-rib plate. At the same time, while fixing the U-rib plate, the two limiting rollers can also roll on the U-rib plate with the two welding guns, reducing friction.

[0020] 3. The controller turns on the third motor switch. The output shaft of the third motor drives the rotating rod to rotate, which in turn drives two sets of bevel gears to rotate. These two sets of bevel gears then drive two threaded rods on both sides of the bearing column to rotate. The two threaded rods, in conjunction with a pair of corresponding second slide rails, drive the sliding block and two welding torches to move downwards synchronously, adjusting them to the weld position for welding. Simultaneously, the controller turns on the second motor switch. The output shaft of the second motor drives the second threaded rod to rotate, which, in conjunction with the first slide rails on both sides, drives the crossbar and the moving frame to move horizontally, thus performing welding on the U-rib plate. After welding is completed, the cylinder drives the three welding mechanisms to rise. Then, the adjustment handle is manually turned off, and the product is removed through several lifting slots next to the receiving slot. The height of the two welding torches is adjusted synchronously by the two sets of bevel gears, making the welding of the weld more accurate. The three welding mechanisms can simultaneously weld three or more U-rib plates. The lifting slots facilitate the handling of the workers.

[0021] This invention allows for the sequential insertion of U-ribbed web plates via guide plates, followed by manipulation of the controller and rotation of the adjustment lever. This process enables the welding of multiple U-ribbed web plates in a safe, efficient, precise, and controllable manner, significantly improving the welding efficiency of U-ribbed web plates.

Detailed Implementation

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0039] Reference Figure 1A novel automatic welding device for assembling U-rib web plates includes a base plate 1 and a mounting platform 2. The mounting platform 2 is fixedly disposed at the top center of the base plate 1. A working plate 3 is fixedly disposed on the top of the mounting platform 2. A plurality of guide plates 4 are provided at one end of the working plate 3, and a receiving groove 30 is provided on one side of the top of the working plate 3. A plurality of lifting grooves 31 are provided on the outer edge of the receiving groove 30. The device is characterized by further including a controller 5, a trimming mechanism 6, an auxiliary mechanism 7, and three sets of welding mechanisms 8. The trimming mechanism 6 includes a limiting seat 60, three sets of fixing components 61, and three sets of grinding components 62. The limiting seat 60 is fixedly disposed at one end of the top of the working plate 3. The three sets of fixing components 61 are fixedly disposed on one side of the limiting seat 60 in a linear array. The three sets of grinding components 62 are fixedly disposed on one side of the limiting seat 60 in a linear array. The edge assembly 62 and the three sets of fixed assemblies 61 are arranged opposite to each other on the base plate 1, and the three sets of edge grinding assemblies 62 pass through the working plate 3 and are fixedly connected to the working plate 3. The auxiliary mechanism 7 includes a translation assembly 70, a sensing assembly 71 and a lifting assembly 72. The translation assembly 70 is fixedly arranged on the base plate 1 and located on both sides of the mounting platform 2. The sensing assembly 71 is fixedly arranged on one side of the translation assembly 70. The lifting assembly 72 is fixedly arranged on the top of the translation assembly 70. The three sets of welding mechanisms 8 are fixedly arranged in a linear array at the bottom of the lifting assembly 72 and are fixedly connected to the lifting assembly 72. The three sets of welding mechanisms 8 are arranged corresponding to the three sets of edge grinding assemblies 62 at their bottom. The controller 5 is fixedly arranged on the translation assembly 70.

[0040] Reference Figures 2 to 4 The limiting seat 60 shown has three evenly spaced sliding grooves 600 on one side. Each of the three sliding grooves 600 corresponds to one of the three sets of fixing components 61. Each set of fixing components 61 includes an adjusting handle 610, a first threaded rod 611, a clamping block 612, and two limiting blocks 613. The two limiting blocks 613 are symmetrically and fixedly disposed at both ends of the corresponding sliding groove 600. One end of the first threaded rod 611 passes through the two limiting blocks 613 and is rotatably connected to them. The other end of the first threaded rod 611 is connected to the adjusting handle. 610 is fixedly connected, one end of the clamping block 612 is limited and slidably connected to the corresponding slide groove 600, and the clamping block 612 is threadedly connected to the first threaded rod 611. The three slide grooves 600 provide sliding space for the three clamping blocks 612. When the adjusting handle 610 is manually rotated, the adjusting handle 610 drives the first threaded rod 611 to rotate, and the first threaded rod 611 drives the clamping block 612 to move downward, thereby connecting and fixing one end of the U-rib plate. The two limiting blocks 613 play a limiting role for the clamping block 612.

[0041] Reference Figures 5 to 6The work plate 3 shown has a hollowed-out groove 32 at one end, and a mounting base 10 is fixedly mounted on the top end of the base plate 1. Three sets of edge grinding components 62 are arranged in a linear array on the mounting base 10 and all pass through the hollowed-out groove 32. Each set of edge grinding components 62 includes a first motor 620, a first rotating shaft 621, a second rotating shaft 622, a first bevel gear 623, a second bevel gear 624, a support plate 625, and two grinding wheels 626. The first motor 620 is fixedly mounted at an angle on one side of the top of the mounting base 10. The output shaft of 20 is fixedly connected to one end of the first rotating shaft 621 via a coupling. The support plate 625 is fixedly connected to the inner wall of the hollow groove 32. The other end of the first rotating shaft 621 passes through the support plate 625 and is fixedly connected to a corresponding grinding wheel 626. The first bevel gear 623 and the second bevel gear 624 are disposed on one side of the support plate 625 and mesh with each other. The first bevel gear 623 is fixedly connected to the first rotating shaft 621. One end of the second rotating shaft 622 is fixedly connected to the second bevel gear 624, and the second rotating shaft 622... 2. The support plate 625 is fixedly connected to another grinding wheel 626. Each grinding wheel 626 has a grinding groove 6260 in the middle. The hollow groove 32 provides a transition space for the three sets of grinding components 62. When the U-rib web is fed in between the two guide plates 4, the controller 5 turns on the switch of the first motor 620. The output shaft of the first motor 620 drives the first rotating shaft 621 to rotate through the coupling. The first rotating shaft 621 drives the corresponding grinding wheel 626 to rotate. At the same time, the first rotating shaft 621 also drives The first bevel gear 623 rotates, which drives the second bevel gear 624 to rotate. The second bevel gear 624 drives the second rotating shaft 622 to rotate, thereby driving the other grinding wheel 626 to rotate. In turn, the two grinding wheels 626 rotate synchronously. The two sides of the U-rib web plate are inserted into the grinding grooves 6260 of the two grinding wheels 626 along the two guide plates 4 to perform deburring operation. The arrangement of the two grinding wheels 626 effectively removes burrs while also providing some translational force for the U-rib plate.

[0042] Reference Figures 7 to 8The translation assembly 70 shown includes a second motor 700, a second threaded rod 701, a moving frame 702, a first bearing 703, a crossbar 704, two side platforms 705, two first slide rails 706, and two carriers 707. The two carriers 707 are symmetrically and fixedly disposed at the top ends of the base plate 1 and located at the bottom of the mounting platform 2. The two side platforms 705 are symmetrically and fixedly disposed on both sides of the mounting platform 2. The two first slide rails 706 are respectively fixedly disposed on the top of the corresponding two side platforms 705. The second motor 700 is horizontally fixedly disposed on the corresponding carrier 707, and the output shaft of the second motor 700 is fixedly connected to one end of the second threaded rod 701 through a coupling. The bottom sides of the movable frame 702 are slidably mounted on two first slide rails 706. The crossbar 704 is fixedly mounted on the bottom of the movable frame 702. The other end of the second threaded rod 701 passes through the crossbar 704 and is rotatably connected to the first bearing 703. The second threaded rod 701 is threadedly connected to the crossbar 704. The first bearing 703 is fixedly mounted on the corresponding carrier 707. When the sliding block 822 and the two welding torches 84 move downward synchronously and are adjusted to the weld position, the controller 5 turns on the second motor 700 switch. The output shaft of the second motor 700 drives the second threaded rod 701 to rotate, thereby the second threaded rod 701, in conjunction with the first slide rails 706 on both sides, drives the crossbar. 704 and the moving frame 702 translate to perform welding work on the U-rib plate. The first bearing 703 provides a rotating carrier for the second threaded rod 701, and the two first slide rails 706 provide a sliding carrier for the moving frame. The sensing component 71 includes a mounting frame 710, an industrial camera 711, a signal line 712, and two support seats 713. The two support seats 713 are symmetrically and fixedly mounted on corresponding two side platforms 705. The bottom ends of the mounting frame 710 are fixedly mounted on the corresponding two support seats 713. The industrial camera 711 is fixedly mounted in an inverted position at the top center of the mounting frame 710. The controller 5 is fixedly mounted on a corresponding side platform 705 and located on a support seat 705. On the side of 13, the two ends of the signal line 712 are electrically connected to the industrial camera 711 and the controller 5, respectively. As the U-rib moves, the industrial camera 711 on the mounting frame 710 performs image recognition. When one end of the U-rib moves to the bottom of one end of the clamping block 612, the industrial camera 711 cannot recognize the U-rib and transmits this signal to the controller 5 through the signal line 712. The controller 5 then shuts down the first motor 620. The image recognition controls the start and stop of the first motor 620, ensuring that the U-rib automatically detaches when it moves to the bottom of the clamping block 612. This avoids safety hazards and saves energy. The two support seats 713 provide a fixed carrier for the mounting frame 710.

[0043] Reference Figure 9The lifting assembly 72 shown includes a top frame 720, a mounting plate 721, a cylinder 722, a sliding plate 723, and two guide columns 724. The bottom ends of the top frame 720 are fixedly mounted to the top of the movable frame 702. The mounting plate 721 is fixedly mounted to the center of the top of the top of the top frame 720. The cylinder 722 is fixedly mounted on the mounting plate 721 in an inverted position, and the output shaft of the cylinder 722 passes through the top frame 720 and is fixedly connected to the sliding plate 723. The two guide columns 724 are symmetrically mounted and fixedly positioned on the top frame 720. Between the top frame 720 and the movable frame 702, both ends of the sliding plate 723 are slidably connected to the two guide plates 4. When the clamping block 612 moves downward to connect and fix one end of the U-rib plate, the control controller 5 turns on the cylinder 722 switch. The output shaft of the cylinder 722, together with the two guide columns 724, drives the sliding plate 723 to move downward, preparing for the subsequent movement of the sliding plate 723 to drive each bearing column 80 downward. The mounting plate 721 provides a fixed mounting carrier for the cylinder 722.

[0044] Reference Figure 10 Each welding mechanism 8 shown includes a support column 80, a drive assembly 81, two sets of sliding assemblies 82, two sets of buffer clamping assemblies 83, and two welding torches 84. The top of the support column 80 passes through the moving frame 702 and is fixedly connected to the sliding plate 723. The two sets of buffer clamping assemblies 83 are symmetrically hinged to the bottom of the support column 80. The two sets of sliding assemblies 82 are symmetrically and fixedly arranged on both sides of the support column 80. The drive assembly 81 is fixedly connected to both sets of sliding assemblies 82. The two welding torches 84 are symmetrically and fixedly arranged on opposite sides of the two sets of sliding assemblies 82. The support column 80 is located directly above the corresponding set of edge grinding assemblies 62. The drive assembly 81 provides power to the two sets of sliding assemblies 82.

[0045] Reference Figures 11 to 12The drive assembly 81 shown includes a third motor 810, a support plate 811, a rotating rod 812, a second shaft seat 813, and two bevel gear sets 814. The support plate 811 is fixedly mounted on one end of the support column 80. The third motor 810 is horizontally fixedly mounted on one side of the top of the support plate 811, and the output shaft of the third motor 810 is fixedly connected to one end of the rotating rod 812 via a coupling. The other end of the rotating rod 812 passes through the support column 80 and is rotatably connected to the second shaft seat 813. The second shaft seat 813 is fixedly mounted on the other side of the top of the support plate 811. Two sets of bevel gear sets 814 are symmetrically arranged on both sides of the support column 80, and one bevel gear on each set of bevel gear sets 814 is fixedly connected to the rotating rod 812. The rotating rod 812 is rotatably connected to the support column 80. When the controller 5 turns on the switch of the third motor 810, the output shaft of the third motor 810 drives the rotating rod 812 to rotate, thereby driving the two sets of bevel gear sets 814 to rotate. The support plate 811 provides a fixed mounting carrier for the third motor 810 and the second shaft seat 813. Each sliding assembly 82 includes an extension plate 820 and a third threaded rod. 821, a sliding block 822, and two second slide rails 823; an extension plate 820 is fixedly mounted on one side of the bearing column 80, and both ends of the extension plate 820 are symmetrically and fixedly equipped with limiting plates 8200; two second slide rails 823 are symmetrically and fixedly mounted on the extension plate 820 and located between the two limiting plates 8200; one end of a third threaded rod 821 passes through the two limiting plates 8200 and is rotatably connected to the two limiting plates 8200; the other end of the third threaded rod 821 passes through the support plate 811 and is fixedly connected to the corresponding bevel gear set 814; the sliding block... The 822 limit sliding is set on the two second slide rails 823, and the sliding block 822 is threadedly connected to the third threaded rod 821. The two welding guns 84 are symmetrically and fixedly set on the corresponding two sliding blocks 822. The two sets of bevel gears 814 drive the two threaded rods on both sides of the bearing column 80 to rotate. The two third threaded rods 821 cooperate with the corresponding pair of second slide rails 823, thereby driving the sliding block 822 and the two welding guns 84 to move downward synchronously and adjust to the weld position for welding. The extension plate 820 provides a fixed installation carrier for the two second slide rails 823.

[0046] Reference Figure 13Each set of buffer clamping components 83 shown includes a movable plate 830, a limiting roller 831, and two return springs 832. One end of the movable plate 830 is hinged to the bottom side of the support column 80, and the other end of the movable plate 830 is provided with a rectangular hole 8300. The limiting roller 831 is rotatably disposed in the rectangular hole 8300. One end of the two return springs 832 is symmetrically welded to the movable plate 830, and the other end of the two return springs 832 is welded to one end of the extension plate 820. When each support column 80 drives the two limiting rollers 831 at its bottom to fit against both sides of the U-rib plate, the four return springs 832 play a role in buffering and fixing. At the same time, while the two limiting rollers 831 play a role in fixing the U-rib plate, they can also roll synchronously on the U-rib plate with the two welding guns 84 to reduce friction.

[0047] Working principle: The U-rib web is fed between two guide plates 4. The controller 5 turns on the first motor 620. The output shaft of the first motor 620 drives the first rotating shaft 621 to rotate through the coupling. The first rotating shaft 621 drives a corresponding grinding wheel 626 to rotate. At the same time, the first rotating shaft 621 also drives the first bevel gear 623 to rotate. The first bevel gear 623 drives the second bevel gear 624 to rotate. The second bevel gear 624 drives the second rotating shaft 622 to rotate, thereby driving the other grinding wheel 626 to rotate. In this way, the two grinding wheels 626 rotate synchronously. The two sides of the U-rib web are inserted along the two guide plates 4. The U-rib plate is inserted into the grinding grooves 6260 of the two grinding wheels 626 for deburring. As the U-rib plate moves forward, the industrial camera 711 on the mounting bracket 710 performs image recognition. When one end of the U-rib plate moves to the bottom of one end of the clamping block 612, the industrial camera 711 cannot detect the presence of the U-rib plate and transmits this signal to the controller 5 through the signal line 712. The controller 5 then shuts down the first motor 620. At this time, the adjustment handle 610 is manually rotated, which drives the first threaded rod 611 to rotate. The first threaded rod 611 drives the clamping block 612 to move downward, thereby connecting and fixing one end of the U-rib plate. Then, the control is operated. When controller 5 turns on the switch of cylinder 722, the output shaft of cylinder 722, in conjunction with two guide pillars 724, drives the sliding plate 723 to move downwards. The sliding plate 723 drives each bearing pillar 80 to move downwards. Each bearing pillar 80 drives its two bottom limit rollers 831 to fit against both sides of the U-rib plate. Four return springs 832 play a role in buffering and fixing. At this time, controller 5 turns on the switch of the third motor 810. The output shaft of the third motor 810 drives the rotating rod 812 to rotate. The rotating rod 812 drives the two sets of bevel gears 814 to rotate. The two sets of bevel gears 814 drive the two threaded rods on both sides of the bearing pillar 80 to rotate. The two third threaded rods... Rod 821, in conjunction with a pair of corresponding second slide rails 823, drives sliding block 822 and two welding guns 84 to move downwards synchronously, adjusting to the weld position for welding. At the same time, controller 5 turns on the second motor 700 switch, and the output shaft of the second motor 700 drives the second threaded rod 701 to rotate. Thus, the second threaded rod 701, in conjunction with the first slide rails 706 on both sides, drives the crossbar 704 and the moving frame 702 to move horizontally, thereby performing welding work on the U-rib plate. After welding is completed, cylinder 722 drives the three sets of welding mechanisms 8 to rise, and then manually unscrews the adjusting handle 610 to remove the product through several lifting slots 31 next to the receiving slot 30.
