Abstract
Description
Technical Field
[0001] The invention relates to the technical field of intelligent manufacturing in the construction industry, and in particular to an automatic grabbing and binding device. Background Art
[0002] In modern building construction, the binding of steel bars is a key link in structural safety, and its efficiency and precision directly affect the overall quality and construction progress of the project. Traditional steel bar binding work mainly relies on manual operation, which is not only labor-intensive and inefficient, but also difficult to ensure the consistency and quality of binding, especially when facing large-scale and complex steel mesh structures, its disadvantages are more significant.
[0003] In order to meet these challenges, a variety of rebar tying robots have emerged in the market in recent years, aiming to improve tying efficiency and accuracy through automation. However, existing rebar tying robots still face many bottleneck problems in practical applications, which limits their further promotion and application.
[0004] First, existing steel bar tying robots generally adopt a single-point tying working mode, that is, the robot moves one by one to the intersection of the steel bars to perform tying operations. The significant disadvantage of this method is its low efficiency. Each tying operation takes from several seconds to tens of seconds. In large components such as floor slabs, there are many steel bar intersections, often dozens or hundreds. The single-point tying mode is difficult to meet the needs of fast construction. In addition, single-point tying may also lead to uneven distribution of tying points, affecting the overall mechanical properties of the structure.
[0005] Secondly, the scene layout of the existing rebar tying robot before operation is complex and time-consuming. Since the robot needs to operate on a relatively fixed platform, before the tying operation, the construction workers must first take out the steel bars one by one and arrange them in a specific arrangement, and then fix them manually or by other means. This process not only increases labor costs, but may also cause placement errors due to human factors, thereby affecting the accuracy and stability of the tying. What's more serious is that when faced with a complex and changing construction environment, this method of relying on manual layout of the work scene is often difficult to adapt to.
[0006] Furthermore, existing rebar tying robots also have obvious deficiencies in tying point recognition. Most robots use monocular cameras for image acquisition and analysis and positioning. Although this method can achieve basic tying point recognition functions, the recognition speed is slow and easily affected by environmental factors. Especially when dealing with non-planar meshes (such as trapezoidal steel meshes), due to the limited camera field of view and the complexity of steel bar arrangement, it is easy to miss or misidentify tying points, resulting in loose tying or even omissions, which brings safety hazards to the project.
[0007] In summary, existing rebar tying robots have obvious technical defects in tying efficiency, operation scene layout, and tying point identification. These problems not only limit the in-depth application and development of robot technology in the field of rebar tying, but also restrict the modernization process of construction. Therefore, there is an urgent need for a rebar tying system that can overcome the above defects and realize high efficiency, precision and high degree of automation to meet the urgent needs of modern construction.

[0069] like Figures 1 to 16 As shown, the present application discloses an automatic grabbing and lashing device, including a grabbing and lashing assembly 100, wherein the grabbing and lashing assembly 100 includes:
[0070] The gantry 1 comprises a vertical beam 11, a first connecting cross beam 12 and a moving assembly 13, wherein the first connecting cross beam 12 is arranged on the vertical beam 11, and the moving assembly 13 is arranged at the lower end of the vertical beam 11 and can drive the gantry 1 to move or lock;
[0071] The grabbing and tying mechanical arm 2 is arranged on the first connecting crossbeam 12 and is arranged in a plurality along the length direction thereof. The grabbing and tying mechanical arm 2 comprises a lifting device 3, a grabbing device 4, and a tying device 5. The lifting device 3 is connected to the first connecting crossbeam 12 and can control the grabbing device 4 and the tying device 5 to move up and down in the vertical direction.
[0072] The grabbing and lashing components 100 are provided in at least two groups, and at least two grabbing and lashing mechanical arms 2 are provided on the gantry 1 of each group of the grabbing and lashing components 100;
[0073] During operation, at least two groups of the grabbing and binding components 100 control the lifting device 3 to drive the grabbing device 4 to move down to grab the steel bars and place the steel bars at the specified position. After the longitudinal steel bars 201 and the transverse steel bars 202 grabbed by the grabbing and binding components 100 are stacked into a grid-like skeleton, the binding device 5 is controlled to spin and bind the cross-shaped positions of the grid-like skeleton.
[0074] When building the base surface at the construction site, the steel bars need to be stacked horizontally and vertically into a grid to form the skeleton of the building. After the steel bars are stacked into a grid, steel wire ropes need to be tied at the cross positions of the grid to fix the steel bars. Usually, the steel bar tying work on the construction site is done manually by workers, which has the disadvantages of difficulty in fixing the steel bars, large workload, and low efficiency. In addition, the steel bars used for tying are not fixed at the construction site, and even the stacked material area will have various scattered situations. Traditional mechanized means have great difficulty in identifying the specific locations of these scattered steel bars, which can easily lead to inaccurate grasping or omissions. Before tying, the steel bars need to be manually sorted and fixed. This process is not only time-consuming and labor-intensive, but also prone to human errors, such as uneven placement of steel bars and loose fixation, which further increases the difficulty and uncertainty of the tying work and affects the subsequent tying work.
[0075] The present application discloses an automatic grabbing and binding device, which integrates the grabbing and binding functions into a single grabbing and binding mechanical arm 2. Through highly modular design and intelligent control, it significantly improves construction efficiency and flexibility. When in use, after the system is started, the gantry 1 is driven by the moving component 13 to accurately move to the top of the steel bars to be grabbed. The moving component 13 ensures that the gantry 1 can stably and accurately reach the specified position through preset path planning or real-time sensor feedback, or in combination with workers' pushing, etc.; after the gantry is positioned, the multiple grabbing and binding mechanical arms 2 located on the first connecting beam 12 are immediately started, and the lifting device 3 inside the mechanical arm descends according to the control command, driving the grabbing device 4 to contact and clamp the steel bars. The grabbing device 4 adopts a high-precision clamping mechanism to ensure that even in the face of scattered steel bars, it can Accurate grasping is achieved to avoid omission or misgrabbing; after grasping the steel bar, the lifting device 3 drives the grasping device 4 and the steel bar to rise to a safe height, and then the gantry moves to the steel bar placement station through the moving component 13. During this process, multiple groups of grasping and binding components 100 work together to grasp the longitudinal steel bar 201 and the transverse steel bar 202 respectively, and accurately stack them at the designated position to form a grid-like skeleton; the binding device 5 has been lowered to the cross intersection position under the action of the lifting device 3, and the binding device 5 has a built-in wire-spinning device 57, which realizes automatic binding of the steel bar intersection by accurately controlling the wire-spinning amount and position. After the binding is completed, the binding device 5 rises and resets to prepare for the next operation. During the whole process, the grasping and binding mechanical arm 2 can continuously complete multiple steps such as grasping, handling, stacking, and positioning binding without changing tools or adjusting positions, which greatly shortens the operation cycle and improves construction efficiency. At the same time, the parallel operation capability of multiple groups of grasping and binding components 100 enables the system to process multiple steel bars at the same time, further improving the overall work efficiency. In the example of the present application, the lifting device 3 can simultaneously drive the grasping device 4 and the binding device 5 to move up and down as a whole, and can also independently drive the two to move up and down separately.
[0076] The automatic grabbing and binding device disclosed in the present application, through modular design and intelligent control, highly integrates the grabbing and binding functions of steel bars on a single robotic arm, and realizes the automated processing of scattered steel bars through the precise coordination of the gantry and the mobile components, so that the system can process multiple steel bars at the same time, reducing equipment switching time and manpower requirements, significantly shortening the construction period, and reducing construction costs. At the same time, it can automatically adapt to steel bars in different stacking states and can perform accurate operations without manual sorting, thereby enhancing the adaptability of the construction environment and the flexibility of the system.
[0077] As a preferred example of the present application, the gripping device 4 includes a first connecting seat 41, a first swing arm 42, a first connecting arm 43 and a clamping jaw assembly 44, which are arranged in sequence. The first connecting seat 41 is used to be detachably connected to the lifting device 3. The first swing arm 42 is hingedly connected to the first connecting seat 41 and swings under the action of the first driving device 45. The end of the first swing arm 42 away from the first connecting seat 41 is connected to the first connecting arm 43. The first connecting arm 43 and the first swing arm 42 move as a whole. The clamping jaw assembly 44 is arranged at the cantilever end of the first connecting arm 43 away from the first connecting seat 41. The clamping jaw assembly 44 is clamped or released under the action of the second driving device 46. As an example of the present application, the clamping jaw assembly 44 includes a first clamping jaw 441 and a second clamping jaw 442. The first clamping jaw 441 and the second clamping jaw 442 form a scissor-shaped clamping structure. The second driving device 46 is arranged on the first connecting arm 43. The second driving device 46 can drive the first clamping jaw 441 and / or the second clamping jaw 442 to move relative to each other for clamping or releasing. The scissor-shaped clamping structure is driven by a driving device to clamp or loosen. In the prior art, there are many ways to achieve this, such as through a slider, a screw connecting rod, a tension spring, etc. The specific structure of the drive will not be described in detail in this application.
[0078] This setting discloses a specific structure of a gripping device 4, which realizes precise gripping through a multi-stage connection and driving mechanism. Starting from the top, the gripping device 4 is first detachably connected to the lifting device 3 through a first connecting seat 41 to realize position adjustment in the vertical direction; then, the first swing arm 42 is hinged to the first connecting seat 41, and is driven by a first driving device 45, so that the first swing arm 42 swings flexibly along the hinge axis to adjust the gripping direction; the first connecting arm 43 is fixedly connected to the first swing arm 42, and moves synchronously with it to further transmit and adjust the gripping posture; finally, the clamping jaw assembly 44 is arranged at the far end of the first connecting arm 43, and through the action of the second driving device 46, the first clamping jaw 441 and the second clamping jaw 442 are driven to form a scissor-like clamping structure to realize precise clamping and release of the target steel bar. The whole process combines the three main actions of lifting, swinging and clamping, which work together to ensure that the grasping device 4 can flexibly adapt to the grasping needs in different scenarios, realize the multi-dimensional movement of the grasping device 4 in space, expand the grasping range and angle, and greatly broaden the breadth and accuracy of the grasping operation.
[0079] As a preferred example of the present application, the binding device 5 includes a second connecting seat 51, a second swing arm 52, a second connecting arm 53 and a silk-spinning device 57 which are arranged in sequence. The second connecting seat 51 is used to be detachably connected to the lifting device 3. The second swing arm 52 is hingedly connected to the second connecting seat 51 and swings under the action of a third driving device 54. The end of the second swing arm 52 away from the second connecting seat 51 is connected to the second connecting arm 53. The second connecting arm 53 and the second swing arm 52 move as a whole. The silk-spinning device 57 is arranged at the cantilever end of the second connecting arm 53 away from the second connecting seat 51. Under the action of the fourth driving device 55, the silk-spinning device 57 spins silk toward the cross intersection of the grid-like skeleton and binds and cuts it off to form a binding cross 7.
[0080] This setting discloses a specific structure of a binding device 5, whose overall design concept and layout are similar to those of the grasping device 4. Through the collaborative work of modular components, an efficient binding operation of the grid-like skeleton is realized. When performing the binding operation, first, the binding device 5 is lowered to an appropriate binding height by the lifting device 3; then, the second swing arm 52 and the second connecting arm 53 are driven to swing to a predetermined position by the third driving device 54; finally, the fourth driving device 55 is started to make the silk-spinning device 57 spit out silk threads to the cross intersection of the grid-like skeleton and complete the binding and cutting operation. The whole process has a high degree of automation, which can effectively improve production efficiency and product quality. By adopting a modular design concept, the components are tightly connected and easy to disassemble and assemble, which not only simplifies the installation and maintenance process, but also improves the flexibility and adaptability of the equipment, and can meet the operation requirements in different scenarios. In addition, the coordinated movement of the second swing arm 52 and the second connecting arm 53 ensures the smoothness and accuracy of the binding action, so that the silk-spinning device 57 can be accurately positioned at the cross intersection of the grid-like skeleton for binding operations, effectively avoiding the misalignment and missing binding problems that may occur in traditional manual binding, reducing manual labor intensity, ensuring the stability and consistency of the binding process, avoiding errors caused by human factors, improving production efficiency and product quality, reducing costs for enterprises, and enhancing market competitiveness.
[0081] As a preferred example of the present application, the wire-spinning device 57 includes a fourth connection seat 571, a positioning sleeve 572 and a wire-binding installation assembly 573. The positioning sleeve 572 is arranged on the fourth connection seat 571 and is located on one side of the wire-binding installation assembly 573. The fourth connection seat 571 is arranged on the third connection seat 56 and is rotated by the first transmission gear 58. The third connection seat 56 is fixedly arranged on the second connection arm 53. When in use, the wire-binding installation assembly 573 is used to accommodate and install the binding wire coil. The end of the binding wire coil is arranged along the fourth connection seat 571 and the positioning sleeve 572.

Through the optimized design of the spinning device 57, the automatic spinning and positioning winding of the binding wire are realized, which not only simplifies the steel bar binding operation process, but also significantly improves the automation and efficiency of the steel bar binding operation.
[0083] As a preferred example of the present application, the gantry 1 has two groups of vertical beams 11, and the two groups of vertical beams 11 are respectively located at the opposite ends of the first connecting beam 12, and the first connecting beam 12 can move up and down along the vertical beam 11. A base 15 is provided at the lower end of the vertical beam 11, and the moving assembly 13 is provided on the lower surface of the base 15. As a specific example of the present application, a downwardly bent lifting shaft 14 is provided at the opposite ends of the first connecting beam 12, and the lifting shaft 14 is sleeved on the vertical beam 11 and can move up and down along the vertical direction, so as to adjust the height of the first connecting beam 12 in the vertical direction.

At the same time, the introduction of universal rollers allows the gantry 1 to be at ease in complex and changeable construction environments, and improves the reliability and safety of the overall operation.
[0086] As a preferred example of the present application, 4 to 12 grabbing and binding robot arms 2 are arranged along the length direction of the first connecting beam 12, and the grabbing device 4 and the binding device 5 in each grabbing and binding robot arm 2 can be interchanged in the left and right positions on the corresponding lifting device 3.

Each group of gantry 1 is equipped with a grabbing and binding mechanical arm 2 with an integrated grabbing device 4 and a binding device 5 to work in coordination. When working, the multiple grabbing devices 4 of different grabbing and binding assemblies 100 first accurately grab the longitudinal steel bars 201 and the transverse steel bars 202, and keep the steel bars stably clamped during the binding process without loosening, ensuring the accuracy of the steel bar position; then, the binding device 5, with the auxiliary fixation of the grabbing device 4, quickly finds the cross point where the steel bars cross and performs the binding operation.

[0102] S9: After the binding is completed, the steel frame assembly 200 that has completed the binding work is transported away, and the grabbing and binding mechanical arm 2 is reset.
[0103] The present application discloses an automatic grabbing and tying device, which is operated by at least two groups of grabbing and tying components 100. First, the gantry 1 of at least one group of grabbing and tying components 100 is accurately moved to the position above the steel bar placement, and the grabbing device 4 and the tying device 5 are adjusted to move downward by the lifting device 3. Through the precise control of the grabbing device 4, multiple longitudinal steel bars 201 or transverse steel bars 202 are grabbed at the same time; then, the lifting device 3 is used to lift the initially grabbed steel bars to a preset height and move them to the splicing and tying area of the steel bar frame; in this area, the grabbing device 4 is accurately positioned again to prepare for the cross stacking of the steel bars; at the same time, the gantry 1 of another group of grabbing and tying components 100 repeats this process, grabs the steel bars that cross the former vertically, and forms a cross-cross steel bar layout; finally, the tying device 5 automatically performs wire-spinning and tying at the intersection to achieve a firm connection of the steel bars. The whole process is repeated until a complete steel bar frame assembly is formed, and it is confirmed through verification that all intersections have been tied.
[0104] The automatic grabbing and tying device described in the present application realizes the automatic batch grabbing and tying of steel bars, greatly improves the construction efficiency, reduces the manual operation cost, and is particularly suitable for the heavy task of tying steel bars in large-scale construction projects, significantly accelerating the construction progress. In addition, the grabbing device 4 plays an auxiliary positioning role when the tying device 5 is operating, preventing the displacement or loosening of the steel bars in subsequent construction, improving the quality of the project, canceling the design of the positioning device, and having a clever design, compact structure, easy maintenance and operation, reducing the difficulty of use and the failure rate, and enhancing the flexibility and safety of the construction site.
[0105] As a preferred example of the present application, in step S1, two groups of grabbing and binding assemblies 100 are set to perform mobile grabbing, and the gantries 1 of the two groups of grabbing and binding assemblies 100 are arranged in a front-to-back shape, and the two gantries 1 are arranged at a distance of at least half of the longitudinal steel bar 201 or the transverse steel bar 202, and the grabbing and binding mechanical arms 2 in the front and rear groups of the grabbing and binding assemblies 100 are arranged in a front-to-back corresponding shape.
[0106] By setting up two groups of grabbing and binding components 100 to work in parallel, the initial grabbing and positioning of the steel bars are carried out. The grabbing and binding mechanical arms 2 arranged correspondingly in the front and rear ensure high accuracy and flexibility of the operation, and can adapt to the steel bar binding needs of different specifications and layouts, thereby improving the adaptability and flexibility of the construction, and at the same time doubling the efficiency of steel bar binding, effectively shortening the construction period, and reducing the time cost of the project.
[0107] As a preferred example of the present application, in step S5, the steel bars grabbed by another group of grabbing and tying assemblies 100 are placed at the position corresponding to the tying device 5 in the grabbing and tying assembly 100 in step S4. This setting enables the steel bars grabbed in step S5 to cross with the previously grabbed steel bars and then be reliably tied by the tying device 5, thereby achieving reliable fixing of the steel bars grabbed by the two groups of grabbing and tying assemblies 100, simplifying the complex process of traditional manual or single equipment operation, and greatly improving the accuracy and efficiency of tying.
[0108] As a preferred example of the present application, the grabbing and binding assembly 100 is communicatively connected with a mobile platform, and the mobile platform receives input construction drawings through human-computer interaction. The control unit obtains the size and shape of the longitudinal steel bars 201 and the transverse steel bars 202 to be constructed and the spacing between the longitudinal steel bars 201 and the transverse steel bars 202, and then adjusts the specific positions of grabbing the longitudinal steel bars 201 and the transverse steel bars 202 for placement and splicing in step S4 and step S5. This part of the content can be implemented in combination with the relevant content of the prior art, and is not the focus of protection of this application, so it will not be elaborated here.
[0109] As a preferred example of the present application, the automatic grabbing and tying device also includes a panoramic scanning device 300, and the panoramic scanning device 300 includes a panoramic industrial camera 6, and the panoramic industrial camera 6 is arranged on the gantry 1. The panoramic industrial camera 6 can move along the partially tied steel frame assembly 200 with the gantry 1, identify the steel bar tying information of the entire scene of the steel frame assembly 200, integrate the detection method of image stitching and convolutional neural network, identify the untied feature information, and tie the untied cross nodes by moving the grabbing and tying assembly 100. In the example of the present application, the movement of the gantry 1 of the grabbing and tying assembly 100 can be pushed by people, or it can be made into an automatic mobile chassis, combined with the panoramic industrial camera 6 and the depth camera to move the relevant positions, so as to realize the adaptive positioning of the grabbing and tying assembly 100 for grabbing and tying.
[0110] Specifically, in step S8, the following specific steps are included:
[0111] S81: Work scene image acquisition and panoramic image stitching;
[0112] The panoramic industrial camera 6 moves along the partially tied steel frame assembly 200 through the gantry 1 to obtain a video stream of the working scene, obtains a clear scene video frame image based on the video stream, and saves the clear and complete image for subsequent panoramic image fusion and stitching.
[0113] S82: performing Yolov8-based binding point target detection according to the obtained panoramic image, detecting the bound and unbound intersections, and marking the unbound intersections;
[0114] Since convolutional neural networks have achieved optimized detection results in the field of detection and recognition, they are used in many recognition fields; this operation detection process uses the excellent Yolov8 target detection algorithm framework for detection. Due to the trapezoidal steel bars, training data set images of different scales were collected, 1500 high-level bundled and unbundled images and 1500 low-level image data sets were collected, and the data sets were divided into 70% training sets, 15% validation sets and 15% test sets. The test achieved a detection accuracy that was basically the same as the original model, and achieved good detection results.
[0115] S83: The detected image results are transmitted to the execution terminal, which drives the lifting device 3 to grab the binding assembly 100, moves the binding device 5 to the unbound position, and automatically binds the unbound marked points until all the unbound intersection points marked in S82 are bound.
[0116] The present application discloses a method for verifying whether the cross intersections in a steel bar frame assembly 200 are tied. Through the application of panoramic industrial cameras, comprehensive and no-dead-angle monitoring of the binding status of complex steel bar frame assemblies is achieved, effectively avoiding possible omissions and misjudgments in manual inspections. Combined with the precise recognition capabilities of the Yolov8 algorithm, the system can quickly and accurately locate untied steel bar intersections, greatly reducing the time cost of manual search and confirmation, achieving fast and efficient binding of untied nodes, reducing the labor intensity of workers, and significantly improving the quality and consistency of binding operations.
[0117] As a preferred example of the present application, when performing panoramic image stitching, the following steps are included:

[0119] S812: Implement ORB feature point detection to obtain significant feature points of the image, match feature points between images, calculate a transformation matrix based on the obtained feature point pairs, map the image to another image based on the transformation matrix to achieve alignment, stitch together the same overlapping areas in the images, use an image fusion algorithm to perform a smooth transition between the two images, and achieve seamless stitching;
[0120] S813: Global optimization processing, optimizing the visual effect of the visual image, image cropping and zooming operations, and obtaining a complete panoramic view of the working scene;
[0121] S814: Save the panoramic image dataset.
[0122] This setting discloses a specific panoramic image stitching process. First, the input image set is preprocessed, and advanced image enhancement technology is used to remove noise, adjust contrast, etc. to improve image quality and reduce interference in subsequent processing, laying a solid foundation for subsequent feature point detection and matching, and reducing stitching errors caused by poor image quality; then, the ORB (Oriented FAST and Rotated BRIEF) feature point detection algorithm is used to reduce the computational complexity and improve the stitching speed while ensuring the speed and accuracy of feature point detection, quickly and accurately identify significant feature points in the image, and use these feature points to achieve accurate matching between images; using the matched feature point pairs, the transformation matrix is calculated to accurately map images from different perspectives to the same coordinate system to achieve image alignment and preliminary stitching; the stitching process is as follows: Fig.16 As shown, the panoramic industrial camera 6 acquires four view images during the movement of the gantry 1, namely the first camera view image 61, the second camera view image 62, the third camera view image 63 and the fourth camera view image 64, and forms a view image overlap area 65 between two adjacent view images. In the stitching process, special attention is paid to processing the overlapping area between images. Through an efficient image fusion algorithm, the stitching edge is smoothly transitioned to achieve seamless connection, effectively solving the common problems of ghosting and misalignment in traditional stitching methods, making the stitched panoramic image more natural and smooth. Finally, global optimization processing is performed, including image cropping, scaling and other operations, to further enhance the visual effect, ensuring that the final generated panoramic image is both complete and beautiful, and meets the visual needs in different application scenarios.
[0123] The automatic grabbing and tying device disclosed in the present application integrates a grabbing device and a tying device into a mechanical arm through modular design and intelligent control, and combines the precise positioning of the gantry with the flexible operation of the mechanical arm to achieve full process automation from steel bar grabbing to precise tying, greatly improving the construction efficiency and tying quality, greatly improving the automation level of steel bar grabbing and tying processing, and effectively solving the problems of low efficiency, large workload, and easy errors in traditional manual tying.
