Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for rare earth smelting, and more specifically, to an intelligent robot system for the discharge process of a rare earth smelting furnace. Background Technology

[0002] Rare earth, as a strategic and critical mineral resource, is widely used in high-tech fields such as new energy, electronic information, and aerospace. Its mining and processing stages place extremely high demands on the precision and flexibility of the discharge equipment. Currently, most rare earth discharge equipment on the market adopts a single motion trajectory design, realizing material conveying and discharge through mechanical movement in a single direction. This type of equipment plays a fundamental role in the preliminary processing stage of rare earth due to its advantages of simple structure and controllable cost.

[0003] However, with the increasing trend of refined and diversified development of rare earth products, the limitations of existing discharge equipment in terms of motion trajectory adjustment are becoming increasingly apparent. Individual motion trajectory equipment can only meet the material output requirements of straight lines or fixed angles, making it difficult to achieve flexible adjustments across multiple angles and dimensions according to dynamic changes in the production process. In the deep processing of rare earths, facing materials of different particle sizes and flow rates, as well as diverse discharge requirements, such equipment often cannot provide precisely matched motion trajectories, leading to problems such as low discharge efficiency and poor uniformity.

[0004] This lack of ability to adjust the trajectory of materials not only limits the improvement of rare earth production efficiency and product quality, but also increases production costs and energy consumption for enterprises. When the production process requires frequent adjustments to the discharge angle or height, operators need to spend a lot of time disassembling and reassembling the equipment, which not only reduces production continuity, but may also cause equipment damage due to human error.

[0039] 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.

[0040] 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.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] refer to Figures 1 to 5 An intelligent robot system for the discharge process of a rare earth smelting furnace according to an embodiment of this application includes: a first support component, a first drive device 2, a second support component, a robotic arm component, and a discharge component.

[0046] The first support component includes a first guide rail structure 1 extending horizontally. The first guide rail structure 1 provides a horizontal motion track foundation for the entire system, enabling the components mounted on it to move laterally in the horizontal direction, thereby expanding the range of motion of the robot system in horizontal space and facilitating subsequent precise positioning of the material discharge location.

[0047] The first drive device 2 is mounted on the first support assembly and can move along the first guide rail structure 1. As a power source, the first drive device 2 drives itself and its connecting components to move along the first guide rail structure 1, realizing active horizontal movement of the system. It can flexibly adjust its position according to material discharge requirements, thus improving the system's maneuverability.

[0048] The second support component includes a second guide rail structure 3 extending vertically and connected to the first guide rail structure 1. The vertical arrangement of the second guide rail structure 3, perpendicular to the first guide rail structure 1, provides a vertical movement track for the robotic arm assembly. This allows the robotic arm assembly to move not only horizontally but also vertically, further expanding its range of motion in space and enabling it to reach different heights within the melting furnace for material discharge operations.

[0049] The robotic arm assembly includes a second drive unit and a drive arm 4. The drive arm 4 is mounted on a second guide rail structure 3 via a drive arm base 17. The second drive unit is located on the second guide rail structure 3 and connected to one end of the drive arm 4, allowing the drive arm 4 to swing around that end in a vertical plane. The second drive unit provides the drive arm 4 with the power to swing in the vertical plane, enabling the drive arm 4 to swing about the connection point as an axis. This swinging function, combined with the movement of the first guide rail structure 1 and the second guide rail structure 3, allows the robotic arm assembly to achieve more complex and flexible spatial movements, facilitating the precise scooping and pouring of rare earth molten materials.

[0050] The discharge assembly includes a scoop 5 extending vertically, with its top end rotatably connected to the other end of the drive arm 4. As the component that directly contacts and transfers the molten rare earth material, the vertical arrangement of the scoop 5 facilitates its insertion into the smelting furnace to scoop the molten material. Its rotatable connection to the drive arm 4 allows the scoop 5 to follow the movement of the drive arm 4 while also adjusting its angle according to actual needs, facilitating the pouring action and ensuring the molten material is accurately transferred to the target location. This design improves the range of motion of the robotic arm in both horizontal and vertical directions and is specifically designed for discharge and pouring actions. This intelligent robot system can efficiently and accurately complete the discharge process from the rare earth smelting furnace, significantly improving discharge efficiency and quality compared to traditional methods, while reducing the safety risks of manual operation.

[0051] In some embodiments, the first support assembly further includes a first support truss 6 and a second support truss 7.

[0052] The first support frame 6 extends vertically to a set height. The first support frame 6 provides a vertical support foundation for the entire first support assembly, increases the stability of the support structure in the vertical direction, and can withstand the forces generated by components such as the first drive device 2 during movement, preventing the system from swaying or tilting in the vertical direction.

[0053] The second support frame 7 extends horizontally and connects to the top of the first support frame 6. The first guide rail structure 1 is mounted on the second support frame 7. After the second support frame 7 is connected to the first support frame 6, a stable support structure is formed. The first guide rail structure 6 is mounted on the second support frame 7, which provides stable support for the first guide rail structure 1, enhances the structural strength of the entire first support assembly in the horizontal direction, ensures the stability and reliability of the first drive device 2 when moving on the first guide rail structure 1, and avoids movement deviation or component damage due to insufficient structural strength.

[0054] The combination of the first support frame 6 and the second support frame 7 can increase the structural strength of the support, provide a stable support foundation for the entire intelligent robot system, ensure the stability and reliability of the system during operation, and help improve the service life and work efficiency of the system.

[0055] In some embodiments, the second support truss 7 includes a first horizontal bar 701 and a second horizontal bar 702.

[0056] The extension direction of the first horizontal rod 701 is perpendicular to the extension direction of the second horizontal rod 702, and one end of the first horizontal rod 701 is connected to the middle of the second horizontal rod 702, so that the cross-section of the second support frame 7 in the horizontal direction is "T" shaped. This "T" shaped structural design increases the support area and stability in the horizontal direction. Compared with a single rod structure, it can better distribute and bear the forces applied by the first guide rail structure 1 and the first drive device 2, thereby improving the load-bearing capacity and deformation resistance of the second support frame 7 in the horizontal direction.

[0057] Accordingly, there are three first support frames 6, which are connected to the first, second, and third ends of the second support frame 7, respectively. The connection between the three first support frames 6 and the second support frame 7 forms a more stable three-dimensional support structure, supporting and fixing the second support frame 7 from multiple directions. This further enhances the structural strength and stability of the entire first support assembly, effectively resisting external forces from different directions during the operation of the robot system, and ensuring stable operation of the system under complex working conditions.

[0058] In some embodiments, the first driving device 2 includes a first driving motor, and a first driving gear 9 is disposed on the output shaft of the first driving motor. The first driving motor serves as a power source, driving the first driving gear 9 to rotate through the output shaft, thereby providing power for the movement of the first driving device 2 on the first guide rail structure 1.

[0059] Preferably, the first guide rail structure 1 includes an arc-shaped rack 8, which comprises a first strip portion 801, an arc-shaped portion 802, and a second strip portion 803. The first strip portion 801 is disposed on one side of the first horizontal rod 701 and parallel to the extension direction of the first horizontal rod 701. The second strip portion 803 is disposed on one side of the second horizontal rod 702 relative to the first strip portion 801. The arc-shaped portion 802 is located between the first strip portion 701 and the second strip portion 702 and is connected to both. The special structural design of the arc-shaped rack 8 allows the first drive gear 9 to mesh along different parts of the arc-shaped rack 8 during rotation, thereby enabling the first drive motor to reciprocate between the first end and the second end, or between the first end and the third end. This not only expands the horizontal movement trajectory of the first drive device 2, allowing it to move within a wider range, but also enables the realization of more complex movement paths through the cooperation of different parts, improving the horizontal movement flexibility and positioning accuracy of the robot system.

[0060] The cooperation between the first drive motor, the first drive gear 9, and the arc rack 8 enables the first drive device 2 to move flexibly and precisely within a specific horizontal range, providing reliable power and movement for the entire intelligent robot system in the horizontal direction, which is conducive to improving the efficiency and accuracy of material discharge operation.

[0061] In some embodiments, the first guide rail structure further includes a V-shaped guide rail, on which the first drive motor is slidably mounted via a V-shaped wheel. The V-shaped guide rail and the V-shaped wheel have V-shaped cross-sections, and the wheel body can extend into the V-groove of the V-shaped guide rail. This provides guidance and support for the sliding of the first drive motor on the first guide rail structure 1, and effectively limits the lateral displacement of the first drive motor during sliding, ensuring stable sliding along the direction of the V-shaped guide rail and improving the smoothness and accuracy of the first drive device's movement. Simultaneously, the relatively large contact area between the V-shaped guide rail and the V-shaped wheel allows it to withstand larger loads, enhancing the load-bearing capacity of the first drive device during movement and ensuring the stability and reliability of the system during operation.

[0062] In some embodiments, in the initial state, the extension direction of the drive arm 4 is perpendicular to the extension direction of the scoop 5. The perpendicular relationship between the drive arm 4 and the scoop 5 is beneficial for the subsequent movement of the robotic arm assembly to drive the scoop 5 to make accurate position adjustments and angle changes, which is convenient for operators to control and operate the system. At the same time, it provides a stable and repeatable starting condition for the automated operation of the system, ensuring that each discharge operation can start from the same initial state, thus improving the consistency and accuracy of the operation.

[0063] In some embodiments, the discharge assembly further includes a third drive device 10 and a housing 11. The third drive device 10 is disposed at the other end of the drive arm 4 and connected to the housing 11, so that the housing 11 swings along a vertical plane. The third drive device 10 provides the power for the housing 11 to swing in the vertical plane. By controlling the swing of the housing 11, the angle and position of the scoop 5 can be further adjusted, making the scoop 5 more flexible in scooping and pouring molten material, and able to adapt to different discharge requirements and working scenarios.

[0064] The box body 11 is also connected to the top of the ladle 5. As a connecting transition component between the ladle 5 and the drive arm 4, the box body 11 connects the ladle 5 to the third drive device 10, so that the ladle 5 can move with the swing of the box body 11. At the same time, it provides a certain support and protection for the ladle 5, and enhances the stability of the ladle 5 during the movement.

[0065] The cooperation between the third drive device 10, the box body 11 and the scoop 5 further improves the flexibility and operability of the discharge component, allowing the scoop 5 to be adjusted within a wider range of angles, improving the system's adaptability to different discharge conditions, and ensuring that the discharge operation can be completed efficiently and accurately.

[0066] In some embodiments, the discharge assembly further includes a cylinder mounting plate 12, a cylinder 13, and a gripper 14. The cylinder mounting plate 12 is disposed inside the housing 11, providing a mounting base for the cylinder 13 and ensuring that the cylinder 13 can be stably installed within the housing 11. The cylinder 13 is located inside the housing 11 and mounted on the cylinder mounting plate 12. The cylinder 13 serves as a power source, generating force through telescopic movement. The gripper 14 is located inside the housing 11 and connected to the cylinder 13. The top of the scoop 5 extends into the housing 11 and is clamped by the gripper 14. The cylinder 13, through telescopic movement, drives the opening and closing of the gripper 14, thereby achieving the clamping and releasing operation of the scoop 5. When the scoop 5 is needed for material discharge, the cylinder 13 drives the gripper 14 to clamp the scoop, ensuring that the scoop 5 will not loosen or fall off during movement, thus guaranteeing the safety and stability of the discharge operation. When the scoop 5 needs to be replaced or maintained, the cylinder 13 drives the gripper 14 to release, facilitating the disassembly and installation of the scoop 5. This achieves reliable fixation and convenient operation of the scoop 5, improving the practicality and maintainability of the discharge component and ensuring the stable operation of the intelligent robot system in the material discharge process.

[0067] In some embodiments, the discharge assembly further includes a heat insulation plate 15, which is disposed at the bottom of the box body 11, and the top of the scoop 5 passes through the heat insulation plate 15 and extends into the interior of the box body 11. During the discharge process of the rare earth smelting furnace, the scoop 5 comes into contact with the high-temperature rare earth molten material. The heat insulation plate 15 can effectively block the high-temperature heat from being transferred from the scoop 5 to the box body 11 and other components, reducing the impact of high temperature on the internal structure of the box body 11 and other components, protecting the normal working performance of components such as the cylinder 13 and the gripper 14, extending the service life of these components, and also improving the safety and stability of the entire discharge assembly when working in a high-temperature environment.

[0068] In some embodiments, the discharge assembly further includes two force sensors 16 located at both ends of the inner side of the housing 11, and each force sensor 16 is in contact with the cylinder mounting plate 12. The force sensors 16 can monitor in real time the magnitude and direction of the force exerted on the ladle 5 during the scooping and pouring of molten material. Based on the information fed back by the force sensors 16, the control system can promptly understand the working status of the ladle 5, such as whether it has scooped up enough molten material or encountered resistance during pouring. According to this information, the control system can precisely control and adjust components such as the first drive device, the second drive device, the third drive device 10, and the cylinder 13 to ensure smooth discharge operation and prevent damage to components due to excessive or uneven force, thus improving the system's intelligence and reliability.

[0069] In some embodiments, the system further includes a third guide rail structure 19 and a fourth driving device. The third guide rail structure 18 is located below the first driving device 2 and connected to it, so that the third guide rail structure 18 moves along the first guide rail structure 1 with the first driving device 2. The third guide rail structure 18 extends horizontally and is perpendicular to the extension direction of the first guide rail structure 1. The second guide rail structure 3 is located below the third guide rail structure 18 and connected to it. The fourth driving device includes a fourth driving motor, which is disposed on the third guide rail structure 18 and is used to drive the second guide rail structure 3 to move along the third guide rail structure 18. Both the first driving device 2 and the fourth driving device can realize the movement of the second guide rail structure 3, the third guide rail structure 18, the ladle 5, etc. in the horizontal plane. The first driving device 2 is mainly used to drive the second guide rail structure 3, the third guide rail structure 18, the ladle 5, etc. to move laterally along the first guide rail structure 1, and can perform large-amplitude and large-range movements, such as moving the robotic arm from the initial position to the position of the rare earth smelting furnace or into the rare earth smelting furnace. The fourth drive motor is mainly used to adjust the position of the second guide rail structure 3 and the ladle 5 in a small range. By detecting the position between the ladle 5 and the inner wall of the rare earth smelting furnace in real time, the position of the ladle 5 is adjusted by the fourth drive motor to maintain a safe distance between the ladle 5 and the inner wall of the smelting furnace and avoid collision between the ladle 5 and the inner wall of the smelting furnace.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
