Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent suspension conveying equipment, and particularly to an intelligent robot for carrying profiles. BACKGROUND

[0002] In industrial production, intelligent suspension conveying systems are widely used in the workshop internal circulation and warehouse docking scenarios of long strip materials such as profiles as an efficient material transfer mode. Among them, the taking and placing link of the profile between the intelligent suspension conveying system and the roadway suspension conveying structure is a key node affecting the overall conveying efficiency. At present, the traditional profile taking and placing equipment often has the problem of single function: some equipment can only realize ground movement, and manual assistance is required to transfer the profile from the ground to the suspension conveying structure, which not only increases the labor intensity, but also easily leads to low docking efficiency due to manual operation errors; another part of the equipment is only suitable for suspension conveying track operation and cannot move to the material taking point of the roadway suspension conveying independently, and needs to rely on additional transfer devices for cooperation, which leads to the fragmentation of the conveying process and high cost of cooperation between equipment. SUMMARY

[0003] The purpose of the present application is to provide an intelligent robot for carrying profiles, which solves the problem of single function of traditional profile taking and placing equipment, which can only move on the ground or only adapt to the suspension track, and needs manual or additional device assistance to complete the taking and placing of profiles between the intelligent suspension conveying system and the roadway suspension conveying structure.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme: An intelligent robot for carrying profiles, comprising: A suspension connecting piece comprising a first connecting column and a second connecting column, the ends of which are rotatably connected; A carrying disc detachably connected to the bottom of the second connecting column, the bottom of which is provided with a suspension auxiliary piece for suspending the profile; A hoisting assembly provided in the second connecting column for hoisting the carrying disc; Four groups of connecting assemblies are evenly distributed on the edges of the carrying disc, each group of the connecting assemblies comprising a connecting arm and a walking wheel; the connecting arm is driven by a motor to realize overturning, and when overturned upward, it cooperates with the second connecting column to form a hoisting structure for the carrying disc, and when rotated downward to a vertical state, it forms a supporting structure for the carrying disc and realizes ground walking through the walking wheel.

[0005] Preferably, the surface of the second connecting column is welded with an annular fixing frame, and the surface of the connecting arm is provided with a clamping groove matched with the fixing frame; when the connecting arm is rotated upward, the clamping groove is clamped with the fixing frame, and the carrying disc and the profile are hoisted by the four groups of connecting arms.

[0006] Preferably, the carrier plate has four movable cavities, each corresponding to one of the four sets of connecting components; each movable cavity is provided with a limiting mechanism, which includes a limiting rod slidably disposed in the movable cavity, and the surface of the connecting arm is provided with an insertion hole adapted to the limiting rod; when the connecting arm rotates downward to a vertical position, the limiting rod slides outward and passes through the insertion hole to limit the rotation of the connecting arm.

[0007] Preferably, the suspension auxiliary component includes a rotating disk, the top of which is integrally formed with a connecting shaft and rotatably connected to the bearing disk via the connecting shaft; the surface of the connecting shaft is provided with limiting teeth, and hooks are uniformly fixed to the bottom of the rotating disk; the end of the limiting rod is fixed with a limiting block that matches the limiting teeth; when the connecting arm rotates upward and engages with the fixing frame, the limiting rod disengages from the insertion hole and moves towards the connecting shaft, and the rotation of the rotating disk is restricted by the engagement of the limiting block with the limiting teeth.

[0008] Preferably, the limiting rod is composed of an "L"-shaped structure and an "I"-shaped structure. The "L"-shaped structure is located at the top center of the "I"-shaped structure, and the limiting block is located at the end of the "I"-shaped structure. A first electromagnet and a third electromagnet are respectively fixed on both sides of the "L"-shaped structure, and a second electromagnet and a fourth electromagnet are respectively fixed on the inner wall of the moving cavity corresponding to the positions on both sides of the "L"-shaped structure. When the first electromagnet and the second electromagnet are energized, they repel each other, pushing the limiting rod to move towards the connecting shaft. When the third electromagnet and the fourth electromagnet are energized, they repel each other, pushing the limiting rod to move towards the connecting arm.

[0009] Preferably, the top center of the bearing plate is provided with an annular groove, and the bottom end of the second connecting column is integrally formed with an annular boss; when the annular boss is located in the annular groove, the "L"-shaped structure at the top of the limiting rod is inserted into the top of the annular boss.

[0010] Preferably, a positioning post is integrally formed at the center of the annular groove, and a positioning groove adapted to the positioning post is provided at the bottom end of the second connecting post.

[0011] Preferably, the hoisting assembly includes a second motor fixed to the side wall of the second connecting column, and a winding reel rotatably connected inside the second connecting column; the output shaft of the second motor is fixed to the winding reel, a steel wire rope is wound on the surface of the winding reel, a T-shaped rod is fixed at the bottom end of the steel wire rope, a hanging groove adapted to the T-shaped rod is provided at the top of the positioning column, and the interior of the second connecting column is hollow to allow the steel wire rope to pass through.

[0012] Preferably, a first motor for driving the second connecting column to rotate is fixedly installed inside the first connecting column.

[0013] Preferably, the circumferential sidewall of the bearing plate is provided with an identification module, which is used to identify the position and obstacles when walking on the ground, and control the walking wheels to walk in a preset direction.

[0014] The present invention has at least the following beneficial effects: This robot is highly compatible with intelligent overhead conveyor systems, precisely coordinating its ground-walking mode with the overhead conveyor in tunnels to pick up and place profiles, achieving efficient connection of the conveying process. Its onboard recognition module (LiDAR + vision camera) and PLC controller form an intelligent control closed loop, enabling it to autonomously plan its path and identify and avoid obstacles, accurately connecting to pick-up and place points without human intervention. This "scenario adaptation + intelligent autonomy" characteristic not only improves the automation level of profile conveying but also reduces errors and efficiency losses caused by manual operation.

[0015] The connecting arm can switch between two unexpected functions—lifting and support—significantly enhancing its practicality. During lifting, it flips upwards to form a four-point symmetrical lifting structure, which, combined with dual positioning, disperses the load, counteracts lateral forces, greatly reduces swaying, and prevents tilting. When supporting the ground, it rotates downwards to form a stable support base, ensuring no displacement of the load-bearing plate. This dual-state design improves reliability throughout the entire process, from suspension operation to transportation.

[0016] The limiting rod can perform three unexpected functions through position switching: fixing the connecting arm, locking the rotating disk, and limiting the annular boss. This simplifies the structure while significantly improving operational stability. When moving on the ground, the limiting rod moves towards the connecting arm and inserts into the socket, firmly fixing the connecting arm in a supported position to prevent swaying during movement. During hoisting and transport, the limiting rod moves towards the connecting shaft, locking the rotating disk through the engagement of the limiting block and limiting teeth to prevent the profile from swaying due to the rotating disk's rotation. Simultaneously, its top structure inserts into the top of the annular boss, further restricting the annular boss and enhancing the connection stability between the bearing plate and the second connecting column. This "one rod, three uses" design reduces the need for additional components and ensures structural stability across multiple dimensions throughout the entire process from support to hoisting.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] Reference Figures 1-6An intelligent robot for handling profiles includes: a suspension connector 1, comprising a first connecting column 11 and a second connecting column 13, the ends of which are rotatably connected; a bearing plate 2, detachably connected to the bottom of the second connecting column 13, the bottom of which is provided with a suspension auxiliary component 4 for suspending the profile; a hoisting assembly 5, disposed inside the second connecting column 13, for hoisting the bearing plate 2; and four sets of connecting assemblies 3, evenly distributed on the edge of the bearing plate 2, each set of connecting assemblies 3 including a connecting arm 31 and a walking wheel 32; the connecting arm 31 is driven by a motor to rotate, when rotating upwards, it cooperates with the second connecting column 13 to form a hoisting structure for the bearing plate 2, and when rotating downwards to a vertical state, it forms a support structure for the bearing plate 2 and walks on the ground through the walking wheel 32.

[0024] The switching between "lifting" and "walking" modes is achieved by flipping the connecting arm 31, without the need for additional equipment assistance, which improves the robot's scene adaptability; the four sets of connecting components 3 are evenly distributed, which can ensure balanced force and improve the overall structural stability.

[0025] Furthermore, an annular fixing frame 16 is welded to the surface of the second connecting column 13, and a slot 33 adapted to the fixing frame 16 is opened on the surface of the connecting arm 31; when the connecting arm 31 rotates upward, the slot 33 engages with the fixing frame 16, and the bearing plate 2 and the profile are hoisted together by the four sets of connecting arms 31.

[0026] The engagement design of the ring-shaped fixing frame 16 and the slot 33 can form a stable four-point hoisting structure, which can significantly reduce the probability of the bearing plate 2 and the profile swaying compared with single-point or two-point hoisting. The welded fixing frame 16 has high connection strength and can withstand large loads, ensuring the safety and reliability of the hoisting process.

[0027] Furthermore, the bearing plate 2 has four movable cavities 22, which correspond one-to-one with the four sets of connecting components 3; each movable cavity 22 is provided with a limiting mechanism 6, which includes a limiting rod 61 slidably disposed in the movable cavity 22, and the surface of the connecting arm 31 is provided with an insertion hole 34 adapted to the limiting rod 61; when the connecting arm 31 is rotated downward to a vertical position, the limiting rod 61 slides outward and passes through the insertion hole 34 to limit the rotation of the connecting arm 31.

[0028] The cooperation between the limiting rod 61 and the socket 34 can stably fix the connecting arm 31 in a vertical support state, preventing the connecting arm 31 from rotating unexpectedly during walking and causing support failure; the four moving cavities 22 correspond one-to-one with the connecting components 3, which can realize independent restriction of each group of connecting arms 31 and ensure the reliability of the support.

[0029] Furthermore, the suspension auxiliary component 4 includes a rotating disk 44, the top of which is integrally formed with a connecting shaft 41, and is rotatably connected to the bearing disk 2 through the connecting shaft 41; the surface of the connecting shaft 41 is provided with limiting teeth 42, and hooks 43 are uniformly fixed at the bottom of the rotating disk 44; the end of the limiting rod 61 is fixed with a limiting block 66 that matches the limiting teeth 42; when the connecting arm 31 rotates upward and engages with the fixing frame 16, the limiting rod 61 disengages from the insertion hole 34 and moves towards the connecting shaft 41, and the rotation of the rotating disk 44 is restricted by the engagement of the limiting block 66 with the limiting teeth 42.

[0030] When moving, the rotating disk 44 can rotate, making it convenient for workers to adjust the direction of the hook 43 to suspend the profile; when hoisting, the limiting block 66 engages with the limiting teeth 42 to fix the rotating disk 44, preventing the profile from shaking or colliding due to the rotation of the rotating disk 44, thus improving hoisting safety; the limiting rod 61 serves two purposes, both fixing the connecting arm 31 and limiting the rotating disk 44, simplifying the structure.

[0031] Furthermore, the limiting rod 61 is composed of an "L"-shaped structure and an "I"-shaped structure. The "L"-shaped structure is located at the top center of the "I"-shaped structure, and the limiting block 66 is located at the end of the "I"-shaped structure. A first electromagnet 62 and a third electromagnet 64 are respectively fixed on both sides of the "L"-shaped structure. A second electromagnet 63 and a fourth electromagnet 65 are respectively fixed on the inner wall of the moving cavity 22 at positions corresponding to both sides of the "L"-shaped structure. When the first electromagnet 62 and the second electromagnet 63 are energized, they repel each other, pushing the limiting rod 61 to move towards the connecting shaft 41. When the third electromagnet 64 and the fourth electromagnet 65 are energized, they repel each other, pushing the limiting rod 61 to move towards the connecting arm 31.

[0032] The movement of the limiting rod 61 is driven by the magnetic repulsion of the electromagnet, which has a fast response speed and precise control, and can quickly switch between two working modes. The combination structure of "L" shape and "I" shape not only meets the cooperation requirements with the electromagnet, but also takes into account the limiting function of the connecting arm 31 and the rotating disk 44, and the structure design is compact.

[0033] Furthermore, the top center of the bearing plate 2 is provided with an annular groove 24, and the bottom end of the second connecting column 13 is integrally formed with an annular boss 14; when the annular boss 14 is located in the annular groove 24, the "L"-shaped structure at the top of the limiting rod 61 is inserted into the top of the annular boss 14.

[0034] An improved structure is added to facilitate the connection between the bearing plate 2 and the second connecting column 13 during hoisting. The engagement of the annular boss 14 and the annular groove 24 enables radial positioning and restricts the horizontal displacement of the bearing plate 2. The "L"-shaped structure inserted into the top of the annular boss 14 further restricts axial displacement. The combination of these two elements significantly improves the overall stability during hoisting and reduces swaying.

[0035] Furthermore, a positioning post 23 is integrally formed at the center of the annular groove 24, and a positioning groove 15 adapted to the positioning post 23 is provided at the bottom end of the second connecting post 13.

[0036] Enhance the positioning accuracy of the bearing plate 2 and the second connecting column 13. The cooperation between the positioning column 23 and the positioning groove 15 can achieve center positioning and ensure high coaxiality when the two are connected; it forms a double positioning structure with the annular groove 24 and the annular boss 14, which further improves the assembly accuracy and connection stability and avoids uneven structural stress caused by misalignment during hoisting.

[0037] Furthermore, the hoisting assembly 5 includes a second motor 51 fixed to the side wall of the second connecting column 13, and a winding reel 52 rotatably connected inside the second connecting column 13; the output shaft of the second motor 51 is fixed to the winding reel 52, a steel wire rope 54 is wound on the surface of the winding reel 52, a T-shaped rod 53 is fixed at the bottom end of the steel wire rope 54, the top of the positioning column 23 is provided with a hanging groove 21 adapted to the T-shaped rod 53, and the interior of the second connecting column 13 is hollow for the steel wire rope 54 to pass through.

[0038] The motor drives the winding reel 52 to reel in and unwind the wire rope 54, and can precisely control the lifting and lowering of the bearing plate 2, making it convenient to disassemble and install the bearing plate 2; the T-shaped rod 53 and the hanging groove 21 are reliably connected, and the hollow second connecting column 13 can protect the wire rope 54 and prevent it from being damaged by external collisions.

[0039] Furthermore, a first motor 12 for driving the second connecting column 13 to rotate is fixedly installed inside the first connecting column 11.

[0040] The first motor 12 drives the second connecting column 13 and the bearing plate 2 to rotate, which facilitates the processing of the profile and avoids the inconvenience of adjusting the profile position during the processing.

[0041] Furthermore, the circumferential sidewall of the bearing plate 2 is provided with an identification module 7, which is used to identify the position and obstacles when walking on the ground, and control the walking wheel 32 to walk in a preset direction.

[0042] The identification module 7 uses a combination of "LiDAR + vision camera". The LiDAR can identify obstacles with a diameter of ≥5cm, and the vision camera is used to identify ground QR codes for positioning. The identification data is processed by the PLC controller built into the carrier plate 2, which controls the walking wheels 32 to turn or start and stop, realizing autonomous obstacle avoidance and path planning. Short-distance transfer of profiles can be completed without manual operation, improving handling efficiency. At the same time, it ensures the safety of the walking process and avoids collisions with other objects.

[0043] A suspended traveling mechanism 8 is installed in the factory, connecting the first connecting column 11 to the traveling carriage 82. The traveling carriage 82 travels on the traveling track 81, thus facilitating suspended transport. The traveling track 81 is usually a channel-shaped steel structure, fixedly installed in the air along a preset path in the factory workshop. The traveling carriage 82 is adapted to the traveling track 81 and can slide along the length of the track. Its bottom is provided with a connection interface for connecting external equipment. Generally, a servo motor is installed inside the traveling carriage 82 with a gear rack or chain drive structure to provide power to the traveling carriage 82. This process is existing technology and will not be described in detail.

[0044] In summary, this intelligent robot for handling profiles, as the core execution device of the intelligent overhead conveying system, can seamlessly connect with automated warehouses and stacker cranes in aisles. It achieves efficient profile transfer by switching between two modes: "ground walking" and "lifting and transfer". During the outbound phase of the automated warehouse or the material retrieval phase of the stacker crane in aisle, the robot moves to the designated position in ground walking mode. In specific use, the four sets of connecting arms 31 rotate downward to a vertical position. The limiting rod 61 is inserted into the socket 34 of the connecting arm 31 under the drive of the third electromagnet 64 and the fourth electromagnet 65 to form a support leg. The walking wheel 32 contacts the ground. The identification module 7, together with the PLC controller, completes the path navigation in the warehouse at a speed of 0.3-0.8 m / s. At the same time, the rotating disk 44 of the suspension auxiliary component 4 can rotate freely, which is convenient for cooperating with the stacker crane to hang profiles. When entering the intelligent suspended conveying stage, the robot switches to the hoisting and transfer mode. In specific use, the first electromagnet 62 and the second electromagnet 63 drive the limiting rod 61 to disengage from the connecting arm 31 and lock the rotating disk 44. The connecting arm 31 flips up and engages with the annular fixing frame 16 through the slot 33 to form a four-point hoisting structure. The bearing disk 2 and the second connecting column 13 are doubly positioned by the positioning column 23 and the annular boss 14. With the help of the hoisting component 5, the lifting adjustment of 0.2-0.5m / s is achieved. The second connecting column 13 driven by the first motor 12 rotates 360° to accurately dock with the material picking port of the intelligent suspended conveying track or the aisle stacker. The two modes are quickly switched by the on and off control of the electromagnets, which meets the full-process automation requirements of "ground transfer-suspended conveying-stacking docking" in the automated warehouse.
