Description

Technical Field

[0001] This invention relates to the field of automated processing technology for steel mesh, and in particular to a steel mesh welding robot and its welding method. Background Technology

[0002] Anchoring mesh, or simply anchoring mesh, is a type of welded steel mesh installed at the ends of prestressed structural members to fix and reinforce the anchoring concrete (or mortar). After the prestressed steel strands (steel strands or wires) are tensioned, their ends are exposed. To protect these ends from corrosion and ensure that the prestress is effectively transferred to the concrete, these ends need to be "wrapped" in concrete; this area is called the "anchoring zone" or "anchoring zone." The anchoring mesh acts like a "skeleton" within this zone, enhancing the integrity of the anchoring concrete and preventing cracking and spalling.

[0003] In the process of developing this invention, the inventors discovered at least the following problems in the prior art: Existing methods for welding anchored rebar mesh largely rely on manual operation, which is not only labor-intensive but also inefficient, and the welding quality is difficult to guarantee consistently. While some automated welding equipment has emerged in the market with the development of automation technology, it is limited by the structure and size of the anchored rebar mesh, resulting in deficiencies in the clamping of rebar segments and the fixing of the rebar mesh, thus affecting the precision and efficiency of the welding. Summary of the Invention

Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] The following is for reference. Figures 1 to 7 This describes a steel mesh welding robot according to an embodiment of the present invention.

[0028] See Figures 1 to 4 According to an embodiment of the present invention, a steel mesh welding robot includes a straightening and shearing machine 1, a mesh welding table 2, a robotic arm 3, an automatic welding arm 4, a stacking station 5, a feeding tray 6, and stacked parts 7.

[0029] The straightening and shearing machine 1 is used to straighten the reinforcing bars and cut them to a predetermined length, forming multiple reinforcing bar segments 8. The length of the reinforcing bar segments 8 is selected according to actual needs and is not limited. The mesh welding table 2 is used to support and position the reinforcing bar segments 8 for welding into reinforcing mesh. The stacking station 5 is used to stack the welded reinforcing mesh. The robotic arm 3 is located between the straightening and shearing machine 1, the mesh welding table 2, and the stacking station 5. The working range of the robotic arm 3 covers the straightening and shearing machine 1, the mesh welding table 2, and the stacking station 5. As the motion execution component of the entire reinforcing mesh welding robot, it is responsible for driving the feeding tray 6 and the stacking components 7 to move between different stations, realizing the transfer of reinforcing bar segments 8 and reinforcing mesh. The feeding tray 6 is rotatably connected to the end of the robotic arm 3, and multiple feeding fixtures 9 are evenly distributed on its outer periphery. The feeding tray 6 can rotate, allowing multiple feeding fixtures 9 on its outer periphery to sequentially clamp the reinforcing bar segments 8 from the straightening shearing machine 1. The number of feeding fixtures 9 corresponds to the number of reinforcing bar segments 8 forming a single reinforcing mesh. The feeding fixtures 9 are configured, driven by the robotic arm 3, to clamp multiple reinforcing bar segments 8 from the straightening shearing machine 1 and place them on the mesh welding table 2 according to a preset arrangement. The automatic welding arm 4 is used to weld the reinforcing bar segments 8 placed on the mesh welding table 2 to form a reinforcing mesh. The end of the automatic welding arm 4 is equipped with a welding device. The specific type of welding device is set according to actual needs and is not limited. For example, a CO2 shielded welding machine is used, resulting in a high-quality weld. The stacking component 7 is installed at the front center of the feeding tray 6 and is configured, driven by the robotic arm 3, to clamp the welded reinforcing mesh and transfer it to the stacking station 5 for stacking.

[0030] The steel mesh welding robot according to embodiments of the present invention achieves fully automated operation from steel bar straightening and shearing to mesh welding and stacking, reducing manual operation steps, greatly shortening the production cycle, and improving production efficiency. The straightening and shearing machine, mesh welding table, and stacking station are rationally designed and compactly laid out, solving the problems of low production efficiency, unstable welding quality, and inability to achieve fully automated operation in existing technologies, thus realizing high efficiency, automation, and precision in steel mesh welding.

[0031] Combination Figure 3 and Figure 4 As shown, the outer periphery of the feeding tray 6 has multiple radially extending protrusions. The feeding fixture 9 includes a base plate, a driving component 10, a clamping component 11, and a mounting plate 13. The base plate is fixedly connected to the protrusions, and the driving component 10 is mounted on the base plate. The mounting plate 13 is connected to the driving component 10. The clamping component 11 is located on the mounting plate 13 and is connected to the driving component 10 for transmission. It is configured to clamp or release the reinforcing bar segment 8 under the drive of the driving component 10. Figure 5 and Figure 6As shown, in one example, the sidewall of the protrusion is a flat surface. The loading fixture 9 is mounted on the flat surface via a base plate, and two adjacent loading fixtures 9 do not interfere with each other when clamping the rebar segment 8. The driving component 10 can be any of a cylinder, an electric actuator, or a hydraulic cylinder. The piston end of the driving component 10 extends along the direction perpendicular to the base plate. The mounting plate 13 is specifically set on both sides of the driving component 10 corresponding to the length direction of the rebar segment 8. Two clamping components 11 are hinged to the upper end of the mounting plate 13. The clamping components 11 are hinged between the two mounting plates 13 via pins. The lower ends of the two clamping components 11 are far apart to form a bent portion, thus serving as the lever arm for driving the clamping components 11. A crossbar is provided on the piston rod of the driving component 10. The two ends of the crossbar are connected to the bent portion via connecting rods 15, so that the clamping components 11 are driven by the extension and retraction of the piston rod of the driving component 10. The two driving components 10 of the same loading fixture 9 are driven synchronously.

[0032] Furthermore, in order to ensure the stability of the clamped steel bar segment 8, the clamping members 11 are arranged in pairs, and the clamping surfaces of the two clamping members 11 arranged opposite each other are provided with arc-shaped notches that match the outer contour of the steel bar segment 8.

[0033] In some embodiments, such as Figure 4 As shown, the robotic arm 3 is equipped with a drive motor, the output shaft of which is connected to the center of the loading tray 6. The loading tray 6 is rotated according to actual needs, and the corresponding stacking components 7 can rotate with it. The stacking components 7 protrude outwards along the axial direction of the loading tray 6 to grip the finished steel mesh. The stacking components 7 are equipped with multiple double-headed telescopic rods 12 and multiple pairs of grippers 14, each pair of grippers 14 connected to the two telescopic ends of the double-headed telescopic rods 12. Driven by the double-headed telescopic rods 12, the grippers 14 move synchronously towards or away from each other to clamp or release the steel mesh. The double-headed telescopic rods 12 are electrically or pneumatically powered, and multiple double-headed telescopic rods 12 are driven synchronously and evenly distributed along the length of the stacking components 7 to ensure the stability of gripping the steel mesh.

[0034] In one example, the gripper 14 is a block structure, and the opposite sides of the same pair of grippers 14 are provided with V-shaped clamping grooves, which can limit the steel mesh and prevent the steel mesh from falling off during the clamping process.

[0035] Combination Figure 1 and Figure 7 As shown, in some embodiments, the mesh welding table 2 includes at least one welding surface, on which multiple blocks 20 for supporting the reinforcing mesh are provided. The top of each block 20 has a limiting groove adapted to the reinforcing bar segment 8. The blocks 20 include two different heights, used to support the upper and lower reinforcing bar segments of the mesh, respectively. Multiple positioning supports 16 are provided around the outer periphery of the blocks for positioning the reinforcing mesh and ensuring the accuracy of the welded mesh.

[0036] Multiple clamping mechanisms are also provided on the welding table. These clamping mechanisms ensure that the reinforcing bar segments 8 do not deflect or shift through vertical compression. The specific type of clamping mechanism is set according to actual needs and is not limited thereto. In one example, the clamping mechanism can be a rotary cylinder. In another example, the clamping mechanism includes a pressure rod 19 and two pressure arms. The pressure rod 19 vertically penetrates the welding table, and the two pressure arms are fixedly connected to the pressure rod 19, arranged perpendicularly to each other in the horizontal plane. The pressure rod 19 is used to drive the pressure arms to move up and down, clamping or loosening the upper and lower reinforcing bar segments of the reinforcing mesh. To prevent interference when picking up and putting down the reinforcing mesh, the pressure arms include a fixed part 17 and a sliding part 18. The fixed part 17 is mounted on the pressure rod 19, and the sliding part 18 is slidably connected to the fixed part 17 in the horizontal direction. Specifically, for automation, the sliding part 18 and the fixed part 17 are respectively connected to both ends of the telescopic mechanism. The telescopic mechanism can be an electric cylinder or a pneumatic cylinder. The sliding part 18 is driven to move horizontally relative to the fixed part 17 by the telescopic movement of the telescopic mechanism, thereby adjusting the working position of the pressure arm. The fixed part 17 is mounted on the pressure rod 19, and the sliding part 18 is slidably mounted on the end of the fixed part 17 away from the pressure rod 19. After the sliding part 18 is retracted by the telescopic mechanism, it is located within the mesh of the steel mesh, so as not to interfere with the placement and removal of the steel mesh.

[0037] This invention also proposes a welding method for a rebar mesh welding robot, based on the rebar mesh welding robot described in the above embodiments. The implementation process of this method is as follows: Step S1: Load the steel bars into the straightening and shearing machine 1. After straightening the steel bars, the straightening and shearing machine 1 cuts them into steel bar segments 8.

[0038] In this embodiment, the straightening and shearing machine 1 straightens the loaded reinforcing bars and removes bends and rust from their surfaces to achieve the specified straightness. Then, according to the preset reinforcing mesh size requirements, the straightened reinforcing bars are cut into reinforcing bar segments 8 of appropriate length.

[0039] In step S2, the robotic arm 3 moves the feeding tray 6 to the straightening and shearing machine, and the multiple feeding fixtures 9 on the outer periphery sequentially clamp the straightening and shearing machine 1, and then place the steel bar segments 8 sequentially onto the mesh welding table 2.

[0040] In this embodiment, the robotic arm 3 moves the feeding tray 6 to the vicinity of the straightening and shearing machine 1 according to a preset program. The feeding tray 6 rotates, aligning one of the feeding fixtures 9 with the rebar segment 8 at the outlet of the straightening and shearing machine 1. The piston rod of the drive unit 10 is pulled down, driving the two clamping members 11 to rotate around the hinge point through the crossbar, so that the two clamping members 11 move closer to each other and clamp the rebar segment 8 using the arc-shaped notch in the middle of the clamping surface. Then, the feeding tray 6 continues to rotate, and the multiple feeding fixtures 9 on the outer periphery sequentially clamp the rebar segment 8 from the straightening and shearing machine 1, and then place them sequentially onto the mesh welding table 2. During the transfer process, the robotic arm 3 adjusts the position and angle of the feeding tray 6 as needed to ensure that the rebar segment 8 is accurately placed at the designated position on the mesh welding table 2.

[0041] Step S3: Weld the steel bar segments 8 on the mesh welding table 2 into a steel mesh.

[0042] In this embodiment, after a sufficient number of steel bar segments 8 are placed on the mesh welding table 2, the automatic welding arm 4 is activated or welding is performed manually. The automatic welding arm 4 is equipped with a welding device at its end, which welds the intersections of the steel bar segments 8 according to a preset welding program. During the welding process, the pad 20 of the mesh welding table 2 positions and supports the steel bar segments 8 through the limiting groove, and the positioning support 16 further ensures the accurate positioning of the steel bar segments 8. The clamping mechanism drives the clamping arm through the clamping rod 19 to press and fix the corresponding steel bar segments 8 on the upper and lower layers of the steel mesh, preventing the steel bar segments 8 from moving during welding and ensuring welding quality.

[0043] In step S4, the robotic arm 3 drives the stacking component 7 to press against the steel mesh from top to bottom, and removes the steel mesh through the gripper 14 and moves it to the stacking station 5.

[0044] In this embodiment, the robotic arm 3 drives the stacking component 7 to move downwards, causing the grippers 14 to press against the reinforcing mesh. Two double-headed telescopic rods 12 extend from the same pair of grippers 14, bringing the two grippers 14 closer together and clamping the reinforcing mesh using V-shaped clamping grooves. Then, the stacking component 7 rotates, and the robotic arm 3 moves the stacking component 7 to the stacking station 5, placing the reinforcing mesh in the designated position for stacking.

[0045] Step S5: Repeat steps S1 to S4 until the preset number of steel mesh welding tasks are completed.

[0046] The welding method of the steel mesh welding robot proposed in this embodiment of the invention has the following advantages: 1. Continuous operation capability: It can operate 24 hours a day without interruption, without rest, and can adapt to high-intensity production needs.

[0047] 2. Parallel processing capability: Multi-station collaboration (such as simultaneous grabbing and welding) reduces process connection time.

[0048] 3. Standardized output: Programmed control eliminates batch differences, making it especially suitable for large-scale repetitive operations.

[0049] 4. Transparent maintenance costs: Compared to hidden costs such as human training and workplace injuries, robot maintenance costs are easier to predict.

[0050] 5. High-risk operation alternatives: Avoid manual contact with high-temperature welding and steel bar rebound (the rebound accident rate can be reduced by more than 90%).
