Description
Technical Field
[0001] This utility model relates to the field of industrial automation technology, specifically to a high-efficiency material conveying device for industrial robots. Background Technology
[0002] Industrial robots are multi-degree-of-freedom mechanical devices that can perform tasks such as handling, welding, and assembly in three-dimensional space through programming or automatic control. They are a core component of modern automated production lines and smart factories in manufacturing. Their core function is to replace manual labor in performing repetitive, high-intensity, and precise operations, thereby significantly improving production efficiency and product consistency. Industrial robot material handling devices are auxiliary equipment specifically designed for industrial robots. Their function is to automatically and accurately transport materials or workpieces to be processed or already processed to the robot's working range. This device is a key link in achieving seamless connection between production units and forming a complete automated production flow. Its efficiency and reliability directly determine the operational efficiency of the entire robot workstation.
[0003] In industrial robot material handling technology, especially in scenarios requiring the lifting and transfer of materials from a low to a high position, existing lifting conveyor devices focus primarily on the lifting function itself, with insufficient consideration given to the protection of the carrying platform. The lack of effective guardrails around the platform makes it highly susceptible to slippage due to inertia when materials accelerate upwards or stop abruptly. This not only damages the materials themselves but also risks the falling workpieces colliding with equipment or personnel below, causing safety accidents. Furthermore, it forces production line interruptions, requiring manual cleaning and reloading, severely disrupting production continuity and rhythm, and reducing overall efficiency. Therefore, those skilled in the art provide a high-efficiency material handling device for industrial robots to solve the problems mentioned in the background art. Utility Model Content

A protective plate is slidably connected inside the storage slot, and the protective plate is fixedly connected to the upper end of the plurality of first springs.
[0009] As a preferred embodiment of the above technical solution, the protective plate has two symmetrically arranged slots on its sidewall. Each of the two mounting blocks has a sliding cavity. A set of second springs is fixedly connected to the inner wall of each of the two sliding cavities. A movable plate is slidably connected to the inner wall of each of the two sliding cavities.

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Please see Figures 1-6 As shown, this utility model provides a technical solution: a high-efficiency material conveying device for industrial robots, including a base 1 for support, a frame 2 and a robot body 3. The frame 2 is fixedly connected to the upper end of the base 1. A transfer component 4 for conveying materials is installed on the upper end of the base 1. A protective component 5 for preventing materials from falling is installed inside the transfer component 4.
[0024] Furthermore, anchor bolts are installed at the four corners of the base 1 to stably fix the base 1 in the designated position, thereby ensuring stable operation of the device. The transfer component 4 is responsible for executing the complete material conveying process from receiving, lifting to handing over, carrying and moving the material to an operating position that is easy for the industrial robot body 3 to grasp. Through automated material transfer, manual intervention and waiting time between processes are significantly reduced, thereby greatly improving the overall conveying efficiency and operational continuity of the production line. At the same time, the protective component 5 integrated inside the transfer component 4 automatically forms a physical barrier during the material conveying process to prevent the material from accidentally slipping or tipping over during the operation of the transfer component 4. Without additional independent operation, it can effectively ensure the stability and safety of the conveying process, protecting the material from damage and avoiding production line interruptions caused by falling, further ensuring the reliability of efficient material conveying.
[0025] It should be noted that: the robot body 3 is fixedly installed in a designated position. The robot body 3 is existing technology and is a multi-degree-of-freedom spatial robotic arm. It consists of a mounting base, waist, upper arm, forearm, wrist and end effector structure. Each joint is equipped with a servo motor and a precision reducer to provide motion and power. Based on the programming instructions of the control system, the robot arm can achieve precise positioning and posture adjustment in three-dimensional space by coordinating the rotation of the servo motors of each joint, thereby driving the end effector to complete the specified production operation tasks such as grasping, handling, assembly and welding. This will not be elaborated here. In addition, a control panel is installed on one side of the frame (2). The control panel is the central control system of the device, including a human-machine interface and a programmable logic controller. Through the internal preset program, it issues timing control instructions to each actuator, accurately coordinates the start and stop sequence and working time of all components, and ensures that the entire material conveying process runs automatically, continuously and efficiently. This will not be elaborated here.
[0026] As one implementation method in this embodiment, please refer to Figures 1-3As shown, the transfer assembly 4 includes a hydraulic cylinder 401, a first support frame 402, and a second support frame 403. The hydraulic cylinder 401 is fixedly installed on the upper end of the base 1. The first support frame 402 is fixedly connected to the lower side of one side of the frame 2. The second support frame 403 is fixedly connected to the upper side of the other side of the frame 2. The output end of the hydraulic cylinder 401 is fixedly connected to a carrying plate 404.
[0027] Furthermore, the hydraulic cylinder 401 fixed to the base 1 drives the load plate 404 at its output end to perform vertical lifting and lowering movements, thereby forming a conveying path for the material to be lifted and lowered in space. At the same time, the first support frame 402 and the second support frame 403 fixed to different height sides of the frame 2 define the starting low position and the target high position of the material conveying, respectively. The hydraulic cylinder 401 provides stable and strong direct lifting power, ensuring the smoothness and reliability of the lifting and lowering process of the load plate 404 carrying the material. The spatial layout of the first support frame 402 and the second support frame 403 clearly plans the automated process of transferring materials from the low position to the high position, laying a solid structural foundation for building an efficient and continuous loading and unloading system.
[0028] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a first conveyor belt device 405 is installed inside the first support frame 402, and a second conveyor belt assembly 406 is installed inside the second support frame 403. An electric push rod 407 is fixedly installed on the upper side of the side of the frame 2 where the first support frame 402 is located. The output end of the electric push rod 407 passes through the frame 2, and a push plate 408 is fixedly connected to the output end of the electric push rod 407.
[0029] Furthermore, the first conveyor belt device 405 integrated in the first support frame 402 is responsible for automatically conveying materials to the top of the carrying plate 404, while the second conveyor belt assembly 406 installed in the second support frame 403 is used to receive and transmit materials that have been lifted to the target height. The electric push rod 407 fixed to the frame 2 drives the push plate 408 at its output end to perform horizontal linear motion, thereby accurately pushing the materials carried on the carrying plate 404 laterally onto the second conveyor belt assembly 406, which significantly improves the efficiency and continuity of material transfer between different workstations.
[0030] It is worth noting that the first conveyor belt device 405 and the second conveyor belt assembly 406 are both existing technologies, including a drive motor, a transmission drum, a surrounding conveyor belt, and idlers that provide support. The drive motor drives the transmission drum to rotate continuously through a reducer and a transmission mechanism. The friction between the transmission drum and the conveyor belt is used to pull the entire circular conveyor belt and the material it supports to move in a directional and continuous linear motion, thereby realizing the automatic transmission and flow of materials. This will not be elaborated further here.
[0031] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the protective component 5 includes a storage slot 501 and two mounting blocks 502. The storage slot 501 is opened on the upper end of the carrying plate 404. The two mounting blocks 502 are fixedly connected to both sides of the carrying plate 404. A plurality of first springs 503 are fixedly connected to the bottom of the inner wall of the storage slot 501. A protective plate 504 is slidably connected inside the storage slot 501. The protective plate 504 is fixedly connected to the upper end of the plurality of first springs 503.
[0032] Furthermore, the storage groove 501 on the upper end of the carrying plate 404 provides vertical sliding space for the protective plate 504, allowing the protective plate 504 to rise and fall within the storage groove 501. The lower ends of multiple first springs 503 are fixed to the bottom of the storage groove 501, and the upper ends are fixed to the protective plate 504. The extension and retraction characteristics of the first springs 503 provide the reset power for the movement of the protective plate 504. The mounting blocks 502 fixed on both sides of the carrying plate 404 provide the mounting base for the subsequent locking mechanism, maintaining the functionality and simplicity of the device.
[0033] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the protective plate 504 has two symmetrically arranged slots 505 on its side wall. Each of the two mounting blocks 502 has a sliding cavity 506. A set of second springs 507 are fixedly connected to the inner wall of each of the two sliding cavities 506. A movable plate 508 is slidably connected to the inner wall of each of the two sliding cavities 506. The two movable plates 508 are respectively fixedly connected to one end of the two sets of second springs 507. A locking block 509 is fixedly connected to one side of each of the two movable plates 508. The two locking blocks 509 pass through the two mounting blocks 502 respectively, and both locking blocks 509 pass through the carrying plate 404. The two locking blocks 509 and the two slots 505 are engaged and locked together.
[0034] Furthermore, the slot 505 on the side wall of the protective plate 504 cooperates with the locking block 509, which can slide within the sliding cavity 506 of the mounting block 502, to achieve mechanical locking. The moving plate 508 slides within the sliding cavity 506 and compresses the second spring 507, which can drive the locking block 509 out of the slot 505 to release the lock. When the external force is removed, the compressed second spring 507 will push the moving plate 508 to reset, thereby causing the locking block 509 to automatically engage with the slot 505 to complete the lock. This provides a stable and reliable mechanical locking mechanism for the lifting and lowering state of the protective plate 504. The cooperation between the locking block 509 and the slot 505 ensures that the protective plate 504 is firmly locked in the raised position when protection is needed, preventing it from accidentally retracting. The automatic reset capability of the second spring 507 makes the locking operation simple and quick, without manual intervention, greatly improving the automation and reliability of the entire protection process.
[0035] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the top of the inner wall of each of the two sliding cavities 506 is provided with a sliding opening 510. The two sliding openings 510 extend to the outside and communicate with the outside. A wedge-shaped push block 511 is slidably connected in each of the two sliding openings 510. The two wedge-shaped push blocks 511 are fixedly connected to the upper ends of the two moving plates 508 respectively. The top of the inner wall of the frame 2 is fixedly connected with two symmetrically arranged top rods 512. The two top rods 512 are respectively facing the two wedge-shaped push blocks 511. The lower end of the base 1 is fixedly connected with multiple support rods 513. The multiple support rods 513 all penetrate the carrying plate 404, and the multiple support rods 513 are slidably arranged in the storage slot 501.
[0036] Furthermore, the wedge-shaped pusher 511 fixed to the upper end of the moving plate 508 is located on the outside through the sliding port 510. When the carrying plate 404 rises, the top rod 512 fixed to the top of the frame 2 will press down on the inclined surface of the wedge-shaped pusher 511, converting the vertical force into a horizontal force, driving the moving plate 508 and the locking block 509 to move inward, compressing the second spring 507 and unlocking it. At the same time, the support rod 513 fixed to the base 1 slides through into the storage slot 501. When the carrying plate 404 descends, its top end will press against the protective plate. At the bottom of 504, the protective plate 504 is forced to slide upward and reset relative to the carrier plate 404 through relative movement. Through the clever cooperation of the push rod 512 and the wedge-shaped push block 511, the protective plate 504 is automatically and unlocked without power after being lifted into place. The support rod 513 provides a precise and reliable lifting force for the reset of the protective plate 504 by utilizing the downward movement of the carrier plate 404 itself. Together, they form a fully automatic and purely mechanical triggering and reset system, ensuring the efficient and reliable connection between the protective function and the conveying process.
[0037] As one implementation method in this embodiment, please refer to Figure 5 and Figure 6 As shown, the inner wall of the storage slot 501 is provided with multiple limiting slots 6, and the side wall of the protective plate 504 is fixedly connected with multiple limiting blocks 7, which are slidably connected in the multiple limiting slots 6 respectively.
[0038] Furthermore, by having a limiting groove 6 formed on the inner wall of the storage slot 501 and a limiting block 7 fixed to the side wall of the protective plate 504, a sliding pair is formed. When the protective plate 504 moves up and down in the storage slot 501, the limiting block 7 is strictly restricted to slide within the track of the limiting groove 6. This ensures that the protective plate 504 maintains a vertical and stable movement trajectory during the lifting process, effectively preventing it from shifting, shaking, or twisting in the horizontal direction, or even becoming stuck and unable to move. At the same time, it also fundamentally eliminates the risk of the protective plate 504 accidentally falling out of the storage slot 501, thereby greatly improving the reliability, stability, and safety of the protective component 5.
[0039] Working principle: The carrying plate 404 in the transfer assembly 4 is in a lowered position, its height is flush with the first conveyor belt device 405. The protective plate 504 in the protective assembly 5 is in an upward-extending state under the support of the support rod 513 and is firmly locked by the cooperation of the locking block 509 and the locking groove 505, forming a guardrail at the edge of the carrying plate 404. The material is placed on the first conveyor belt device 405, and the first conveyor belt device 405 is started, smoothly conveying the material onto the carrying plate 404. At this time, the protective plate 504 effectively prevents the material from falling from the side due to inertia. After the material is in place on the carrying plate 404, the hydraulic cylinder 401 of the transfer assembly 4 pushes the carrying plate 404 upward. During the ascent of the loading plate 404, as it approaches the top position, the push rod 512 fixed to the top of the frame 2 begins to contact and press the wedge-shaped push block 511. The inclined surface of the wedge-shaped push block 511 converts the downward pressure into a horizontal force, pushing the moving plate 508 to compress the second spring 507 and move inward within the sliding cavity 506. The moving plate 508 causes the locking block 509 to disengage from the slot 505 of the protective plate 504. At this point, the locking of the protective plate 504 is released. Under the combined action of its own weight and the rebound force of the first spring 503, the protective plate 504 quickly retracts downward into the storage slot 501 of the loading plate 404. The cooperation of the limiting block 7 and the limiting slot 6 ensures that its descent is smooth and does not come off. At this point, the upper surface of the protective plate 504 descends to be flush with the platform of the carrying plate 404, clearing the way for material ejection. When the carrying plate 404 rises to a designated height flush with the second conveyor belt assembly 406, it stops. The electric push rod 407 of the transfer assembly 4 pushes the push plate 408 to move horizontally, smoothly pushing the material on the carrying plate 404 onto the second conveyor belt assembly 406. The second conveyor belt assembly 406 transports the material to the working area directly below the industrial robot body 3, completing the loading and unloading process. After unloading, the hydraulic cylinder 401 drives the carrying plate 404 to descend. When the carrying plate 404 descends to its lowest position, the upper end of the support rod 513 fixed on the base 1 penetrates the carrying plate 404 and passes through the receiving slot. The support rod 513 slides inward, pressing against the bottom of the protective plate 504. The carrying plate 404 continues to descend, while the protective plate 504 is pressed against by the support rod 513 and moves upward relative to it. This relative movement causes the protective plate 504 to extend out of the receiving slot 501 again, while stretching the first spring 503. When the protective plate 504 is fully extended and its slot 505 is aligned with the position of the locking block 509 again, the previously compressed second spring 507 recovers its deformation, pushing the moving plate 508 and the locking block 509 outward. The locking block 509 re-engages into the slot 505, locking the protective plate 504 back into the extended position, so that the device returns to its initial state and is ready for the next material conveying cycle.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
