[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0027] like Figure 1 As shown, a construction site material management system of this application includes several components, specifically a support frame 1, a multi-degree-of-freedom handling arm 2, an adaptive gripper 3, a mobile platform 4, storage compartments 5, and positioning markers 6.

[0028] The support frame 1 provides support and installation foundation for the entire system; the multi-degree-of-freedom handling arm 2 is mounted on the support frame 1 and can grip and transport materials at different positions; the adaptive gripper 3 is mounted on the end of the multi-degree-of-freedom handling arm 2 and can automatically adjust the gripping method according to the shape and size of the materials to prevent damage or misalignment; the moving platform 4 is connected to the multi-degree-of-freedom handling arm 2 and can move the handling arm horizontally to expand its working range; the storage compartment 5 is fixed on the support frame 1 and is used to classify and store materials of different specifications and weights; the positioning mark 6 is installed at the entrance of the storage compartment 5 and works with the adaptive gripper 3 to ensure that the materials are placed accurately.

[0029] The support frame 1 is made of robust steel and designed as a stable four-corner bracket structure. Sufficient installation space is provided on its upper and side surfaces to facilitate the installation and fixation of the multi-degree-of-freedom handling arm 2 and other components. The multi-degree-of-freedom handling arm 2 consists of a series of interconnected joints 12 arms. These joints 12 arms can achieve six degrees of freedom of movement via motor drive, enabling precise grasping and handling of materials in three-dimensional space. The specific structure of the handling arm typically includes multiple rotatable joints 12 and a telescopic section. These parts are connected by high-performance gear reducers and servo motors, ensuring precise control and high load-bearing capacity of the arm.

[0030] The adaptive gripper 3 is a sensing and adjustment device installed at the end of the multi-degree-of-freedom conveying arm 2. This gripper contains various sensors (such as pressure sensors and force sensors) that automatically adjust the position and pressure of the gripper fingers based on real-time feedback of the material's shape and surface characteristics, gripping materials of different shapes and sizes in the most suitable way. The moving platform 4 adopts a wheeled or rail-type chassis structure and is connected to the base of the multi-degree-of-freedom conveying arm 2. The movement of the moving platform 4 is typically driven by a stepper motor or servo motor, and achieves smooth horizontal movement through precision guide rails or wheel systems, thereby expanding the working range of the conveying arm and improving work efficiency.

[0031] Storage compartment 5 is a three-dimensional storage space composed of multiple independent small compartments. The size of each storage compartment 5 is designed to accommodate the size of different types of materials, ensuring that each type of material can find a suitable storage location. Storage compartment 5 is fixed to the supporting frame 1, whose robust structure can effectively withstand the weight of various materials. Positioning marker 6 is a highly reflective sign installed at the entrance of each storage compartment 5. This marker, through the cooperation of LiDAR, cameras, or other sensing devices with sensors on the adaptive gripper 3, enables the gripper to accurately align with the storage compartment 5, achieving accurate material storage.

[0032] This construction site material management system effectively solves the problems of traditional automated storage and retrieval equipment when handling diverse materials in complex warehouses through the coordinated operation of the aforementioned components. The multi-degree-of-freedom handling arm 2 combined with the adaptive gripper 3 allows the system to flexibly adapt to materials of different sizes and weights, avoiding material damage or misalignment due to improper gripping. The introduction of the moving platform 4 significantly expands the system's working range and improves warehouse management efficiency. Furthermore, the use of storage compartments 5 and positioning markers 6 further enhances the system's accuracy and security, ensuring correct storage, retrieval, and classification management of materials. Through these technical means, the management system improves logistics efficiency while effectively reducing losses caused by improper operation.

[0033] Continue to refer to Figure 1 In one embodiment, the support frame 1 of a construction site material management system according to this application includes a base 7 and a column 8. The base 7 is equipped with wheels 9 at its bottom, allowing the entire system to move flexibly on the construction site and adapt to different working environments. The column 8 is fixedly mounted on the base 7 to support and secure other key components. The column 8 is provided with a guide groove 10, along which the multi-degree-of-freedom handling arm 2 can slide up and down, thereby meeting the requirements for operation at different heights. Through this design, the system can efficiently complete the handling and management tasks of materials on complex construction sites.

[0034] In one embodiment, the base 7 is typically made of a robust metal material with sufficient load-bearing capacity and stability. The wheels 9 can be heavy-duty rubber wheels with brakes to ensure smooth movement and accurate positioning of the system. The column 8 is fixed to the base 7 by welding or bolting to enhance the overall rigidity of the structure. The guide groove 10 can be a T-shaped or U-shaped groove formed on the side of the column 8, and the multi-degree-of-freedom conveying arm 2 is equipped with corresponding sliders or rollers to ensure smooth and precise sliding.

[0035] For example, the guide groove 10 can be designed with a certain depth and width to accommodate the slider on the multi-degree-of-freedom handling arm 2, ensuring the stability and vibration resistance of the slider within the guide groove 10. Furthermore, the height and strength of the column 8 also need to be optimized according to the actual site requirements to adapt to the handling of materials of different types and weights.

[0036] In one embodiment, such as Figure 2 As shown, the multi-degree-of-freedom handling arm 2 of the construction site material management system of this application consists of multiple rotatable arm sections 11, which are connected by joints 12. Each arm section 11 can rotate independently, thereby achieving complex motion trajectories. A torque sensor 13 is integrated within the joint 12, which can detect and provide feedback on the magnitude of the clamping force in real time. This is crucial for preventing damage to materials during handling due to excessive clamping force. The system adjusts the posture and force of each arm section 11 based on real-time data from the sensors, ensuring the safety and efficiency of the handling process.

[0037] In practical implementation, the design of the boom segment 11 must ensure sufficient rotational freedom at each joint 12. Typically, servo motors are used to drive the rotation of each boom segment 11. Torque sensors 13 at the joints 12 are installed inside the mechanical connection, using high-precision strain gauges or other torque detection elements to monitor the clamping force in real time. These sensors transmit the detected data to the control system. The controller 17 adjusts the torque output of the servo motor based on the torque values ​​fed back from the sensors, ensuring that the clamping force applied by the boom segment 11 to the material is within a preset safe range, effectively preventing material damage.

[0038] In one embodiment, the length of the multi-degree-of-freedom handling arm 2 in the construction site material management system of this application is not less than half the maximum stroke of the mobile platform 4. This design ensures efficient material handling at different workstations, achieving the goal of covering the entire warehouse operation area. Specifically, the multi-degree-of-freedom handling arm 2, through its flexible joint 12 structure, can be adjusted to different spatial positions to meet the handling needs in various complex environments. Simultaneously, the length of the handling arm is designed to be at least equal to half the maximum stroke of the mobile platform 4, ensuring that even when the platform is at its extreme position, the multi-degree-of-freedom handling arm 2 can still reach the far end of the work area.

[0039] For example, the multi-degree-of-freedom conveying arm 2 can consist of multiple links and rotary joints 12. These joints 12 can be driven by electric motors to achieve multiple degrees of freedom of movement. Specifically, the multi-degree-of-freedom conveying arm 2 is installed at the front end of the mobile platform 4, and its base is fixed to the platform to ensure structural stability. The links of the multi-degree-of-freedom conveying arm 2 are connected by joints 12, and each joint 12 is equipped with a motor and a position sensor for precise control of the arm's movement trajectory. When the mobile platform 4 moves to a specific workstation, the multi-degree-of-freedom conveying arm 2 can accurately move materials from one location to another through the coordinated movement of the joints 12, ensuring efficient operation throughout the entire warehouse operating area.

[0040] In one embodiment, such as Figure 2 As shown, the adaptive gripper 3 of a construction site material management system according to this application includes multiple fingers 14, each equipped with a tactile sensor 15. The design of the fingers 14 enables the adaptive gripper 3 to automatically adjust its gripping force and direction upon contact with materials, ensuring stable gripping and release. Each finger 14 houses a drive motor 16, which is electrically connected to a controller 17. The controller 17 dynamically adjusts the motor speed based on data feedback from the tactile sensors 15, allowing the gripper to more accurately adapt to materials of different shapes and sizes. The tactile sensors 15 are distributed at different locations on the fingers 14, forming multiple sensing areas. Based on the tactile signals from each sensing area, the controller 17 intelligently identifies the surface characteristics of the material and selects the optimal gripping point, further improving the gripping stability.

[0041] For example, tactile sensors 15 on the fingers 14 can be arranged on the palm, tip, and sides of the fingers 14 to comprehensively detect different parts of the material. The feedback data from each sensor is processed by the controller 17, and the drive motor 16 adjusts its speed and direction according to the instructions, thereby realizing the adaptive clamping of materials of different shapes and sizes by the gripper.

[0042] Return to reference Figure 1In one embodiment, the mobile platform 4 of a construction site material management system according to this application includes a transverse guide rail 18 and a longitudinal guide rail 19. The transverse guide rail 18 is mounted on a base 7, while the longitudinal guide rail 19 is mounted on the transverse guide rail 18. A multi-degree-of-freedom transport arm 2 is mounted on the moving end of the longitudinal guide rail 19 to achieve precise movement within a larger horizontal range of motion. Both the transverse guide rail 18 and the longitudinal guide rail 19 employ a closed-loop control system and have a built-in high-precision encoder 20 to ensure accurate positioning and smooth operation of the multi-degree-of-freedom transport arm 2 in the horizontal direction. Furthermore, the high-precision encoder 20 is connected to the controller 17 in real time via a wireless communication module 21, enabling remote monitoring and adjustment of the mobile platform 4.

[0043] Specifically, in the design of the mobile platform 4, the transverse guide rail 18 is fixed to the base 7 to ensure its stability and reliability. The longitudinal guide rail 19 is fixed to the transverse guide rail 18 through a precise installation method, allowing it to slide freely on the transverse guide rail 18. The multi-degree-of-freedom transport arm 2 is fixed to the longitudinal guide rail 19 through its moving end, thus enabling it to achieve a wide range of horizontal movements as the longitudinal guide rail 19 moves. In the closed-loop control system, the high-precision encoder 20 is located inside the guide rail and is used to monitor the position changes of the guide rail in real time, ensuring precise control of the system through a feedback mechanism. The wireless communication module 21 between the high-precision encoder 20 and the controller 17 ensures the real-time performance and reliability of data transmission, further improving the system's flexibility and response speed.

[0044] For example, in the design of the mobile platform 4, high-quality ball screws and linear guides can be used to construct the transverse guide rail 18 and the longitudinal guide rail 19. These components can ensure low friction and high precision. The high-precision encoder 20 in the closed-loop control system is installed at key parts of the guide rail to monitor the position changes of the multi-degree-of-freedom transport arm 2 in real time, and transmits the data to the controller 17 through the wireless communication module 21. The controller 17 adjusts the motion state of the guide rail according to the received data, thereby achieving precise positioning and smooth operation.

[0045] In one embodiment, such as Figure 3 As shown, in a construction site material management system of this application, the storage compartment 5 is equipped with an adjustable partition 22. The design of the adjustable partition 22 aims to improve the space utilization and flexibility of the storage compartment 5. By adjusting the height and spacing of the partition, materials of different sizes can be stored adaptively, thereby reducing storage space waste and improving the efficiency of classification management. The internal space of the storage compartment 5 thus becomes more diverse and adaptable, capable of meeting the different storage needs of various materials.

[0046] In one embodiment, the adjustable partitions 22 are installed on both sides of the inner wall of the storage compartment 5, with a set of vertical grooves on each side. Sliding blocks matching the grooves are provided on both sides of the partition, ensuring that the partition can slide freely in the vertical direction. Users can adjust the position of the partitions according to actual needs and fix them at the required height using a locking device, ensuring the stability and safety of materials in the storage compartment 5. For example, when storing long steel pipes, the spacing between the partitions can be adjusted to be larger; while when storing small tools, the spacing can be reduced to improve the compactness and orderliness of the storage. Specifically, the locking device can be a screw fixation or a quick-clamping mechanism, facilitating quick installation and adjustment by the user.

[0047] In one embodiment, the location identifier 6 of the construction site material management system of this application takes the form of a QR code label. A unique QR code label is affixed to the entrance of each storage compartment 5. In this way, by integrating a barcode scanning device 23 on the adaptive gripper 3, the system can accurately identify and verify the location information of the target storage compartment 5 when placing materials. This feature ensures that materials can be accurately stored in the designated storage location, improving the efficiency and accuracy of logistics management.

[0048] QR code labels, as a common type of two-dimensional barcode, can contain a wealth of information, such as the specific number of storage compartment 5, storage capacity, and permitted types of materials. In actual operation, when the adaptive gripper 3 approaches a storage compartment 5, the barcode scanning device 23 installed on it automatically reads the QR code label at the entrance of that storage compartment 5. Specifically, the barcode scanning device 23 typically consists of a camera and a decoding module. After the camera captures the QR code image, the decoding module quickly parses the corresponding information and compares it with the system's preset target location data for verification. During this process, if the identified information matches the target location, the material will be placed in that storage compartment 5; if it does not match, the system will issue an alarm, prompting the operator to check and reconfirm the correct placement of the material. For example, when it is necessary to store building materials with a specific number, the adaptive gripper 3 scans the QR code at the entrance of the storage compartment 5 using the barcode scanning device 23, and after verification, accurately places the building materials into that storage compartment 5.

[0049] In actual operation, when this device is used, the entire site material management system will operate in coordination according to the preset workflow. First, the multi-degree-of-freedom handling arm 2 works, grabbing the required materials from the designated location according to instructions sent by the control system. At this time, the adaptive gripper 3 dynamically adjusts according to the shape and size of the materials, ensuring safe and stable gripping of materials of different shapes. After grabbing, the multi-degree-of-freedom handling arm 2 lifts the materials and transfers them to the required horizontal position. During this process, the mobile platform 4 assists the handling arm in moving horizontally, expanding the system's operating range and enabling it to cover a wider area.

[0050] Next, when the target location is within a specific storage compartment 5, the handling arm will precisely navigate using the positioning markers 6 installed at the entrance of the storage compartment 5. The adaptive grippers 3 will fine-tune based on this marker information, ensuring that the material is accurately placed into the storage compartment 5. Furthermore, the storage compartments 5 are designed to categorize and store materials of different types and weights, thus the entire system not only improves the efficiency of on-site material management but also effectively avoids the risk of damage due to incorrect stacking. Overall, through the structural support provided by the support frame 1 and the precise collaboration between all components, the system significantly improves the safety and reliability of material transfer and storage operations on the construction site.

[0051] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
