Description

Technical Field

[0001] This utility model belongs to the field of intelligent logistics technology, specifically relating to a wireless power supply translation track changer. Background Technology

[0002] In the field of intelligent logistics, track-mounted robots are widely used in scenarios such as warehouse cargo transfer and production line material distribution due to their advantages of automation and high efficiency. With the development of wireless power supply technology, in order to avoid problems such as wire dragging and interface wear in traditional wired power supply methods, wirelessly powered track-mounted robots are gradually becoming the industry's upgrade direction. As the core component for track-mounted robots to achieve path switching, the performance of the track changer directly affects the operational continuity and stability of the entire logistics system. Therefore, the demand for coordinated adaptation of wireless power supply and track change functions is becoming increasingly urgent.

[0003] In existing technologies, wirelessly powered track robots generally face power interruption problems when passing through track changers. The track structure and wireless power supply line design of traditional track changers are independent of each other, lacking a matching follow-up power extraction mechanism. This causes the power extraction components and power supply lines to be unable to coordinate stably when the robot passes through the track change area, easily resulting in power disconnection, affecting the robot's operating efficiency, and even causing shutdown failures.

[0004] Meanwhile, the existing track converters suffer from insufficient precision in track processing and assembly. On the one hand, the overall bending of the track is difficult to process, making it hard to precisely control the torsion and perpendicularity, resulting in poor smoothness when the track is connected. On the other hand, the gap between track joints is usually greater than 1mm, which can easily cause severe vibrations when the robot passes through the joints, with vibration rates generally exceeding 0.5G. This not only shortens the service life of robot components but may also cause the carried materials to shift or be damaged, failing to meet the operational requirements of high-precision intelligent logistics scenarios.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following combination Figures 1 to 3 This application will be described in further detail. This application discloses a wirelessly powered translational track changer, including a support assembly, a track assembly, a power supply assembly, and a translational drive assembly; The support components provide the installation foundation for the overall structure; the track components include a straight track structure for the robot to move straight and a curved track structure for the robot to turn. The straight track structure and the curved track structure can be docked by adjusting their positions to change the robot's running direction; the power supply components include a Lizi wire structure for wireless power supply and a power collection structure for power extraction. The Lizi wire structure is deployed corresponding to the track components, and the power collection structure can cooperate with the Lizi wire structure to achieve electromagnetic induction power extraction to power the external track robot and the translation drive components; the translation drive components are connected to the movable track in the track components to drive the movable track to translate, realizing the switching and docking of the straight track structure and the curved track structure.

[0022] Breaking away from the limitations of traditional independent track changing and power supply, this system achieves coordinated path switching and wireless power supply, resolving power outages when the robot crosses tracks and adapting to the continuous operation requirements of intelligent logistics. Straight and curved tracks can be flexibly switched, and the power supply components can simultaneously power the robot's translational drive, simplifying the system structure and improving scenario compatibility.

[0023] The support assembly includes a base plate 4 and a curved rail bracket 10. The base plate 4 is horizontally positioned to provide a fixed carrier for the Lizi cable tray bracket 16 in the translation drive assembly and power supply assembly. The curved rail bracket 10 is fixed to the top of the base plate 4 to support the fixed curved rail I9 in the track assembly. The curved rail bracket 10 and the fixed curved rail I9 are detachably connected to facilitate the installation and maintenance of the fixed curved rail I9.

[0024] The base plate 4 provides a uniform horizontal mounting reference, ensuring the accurate positioning of components such as the translation drive and power supply lines, and avoiding malfunctions caused by inconsistent references. The curved rail bracket 10 is detachably connected to the fixed curved rail I9, allowing maintenance of the curved rail without disassembling the overall support structure, reducing maintenance costs and operational difficulty.

[0025] The straight rail structure of the track assembly includes a straight rail running track I1, a straight rail running track II12, and a translating straight rail I14; the curved rail structure includes a fixed curved rail I9 and a translating curved rail I8. The straight rail running track I1 and the straight rail running track II12 are fixed to the top two ends of the base plate 4 and are symmetrically arranged. The two ends of the translating curved rail I8 can be connected to one side of the fixed curved rail I9 and the straight rail running track I1, respectively. Both the translation straight rail I14 and the translation curved rail I8 are mounted on the translation drive assembly. The translation drive assembly can drive the translation straight rail I14 to dock with the straight rail running track I1, or drive the translation curved rail I8 to dock with the fixed curved rail I9, thereby realizing the path switching of the robot to go straight or turn.

[0026] The translation drive enables rapid switching and docking between the straight translation rail I14 and the curved translation rail I8, allowing the robot to move straight or turn without manual adjustment, adapting to dynamic path requirements. The straight rail running rails I1 and II12 are symmetrically arranged to balance the weight of the rails, reduce deformation caused by force on one side, and ensure uniform force and smooth operation when the robot moves straight.

[0027] The straight track I1, straight track II12, translational straight track I14, fixed curved track I9, and translational curved track I8 all adopt a split structure design. The split track segments are manufactured by high-precision CNC machining. After machining, the verticality error of each track is ≤0.02mm and the torsion error is ≤0.02mm, ensuring the track docking accuracy and robot operation stability.

[0028] The modular design overcomes the limitations of integral track bending and processing. CNC machining ensures that the track's perpendicularity and torsion errors are ≤0.02mm, guaranteeing docking accuracy. High-precision machining avoids robot jamming caused by track shape deviations, improving robot operational stability from a structural perspective and extending equipment lifespan.

[0029] The joint gaps when the straight track I1, straight track II12 and translational straight track I14 are connected are ≤0.02mm; the joint gaps when the straight track I1 and translational curved track I8 are connected are ≤0.02mm; and the joint gaps when the translational curved track I8 and fixed curved track I9 are connected are ≤0.02mm, in order to reduce the vibration of the robot when passing through the track joints and make the vibration rate ≤0.3G.

[0030] The extremely small gap between seams significantly reduces the vibration of the robot when passing through the seams, keeping the vibration rate ≤0.3G. This prevents parts from wearing out due to vibration and the low vibration can prevent the materials carried by the robot from shifting or being damaged, meeting the requirements for operational stability in high-precision intelligent logistics scenarios.

[0031] The Lizi line structure of the power supply component includes a fixed straight rail Lizi line I3, a fixed curved rail Lizi line 11, a fixed straight rail Lizi line II13, a fixed straight rail Lizi line III19, a translational straight rail Lizi line 15, and a translational curved rail Lizi line 17. Fixed straight rail Lizi line I3, fixed curved rail Lizi line 11, fixed straight rail Lizi line II13, and fixed straight rail Lizi line III19 are fixed to the base plate 4 through Lizi line groove bracket 16; The straight translation rail Lizi line 15 and the curved translation rail Lizi line 17 are fixed to the sides of the straight translation rail I14 and the curved translation rail I8, respectively, and move synchronously with the straight translation rail I14 and the curved translation rail I8.

[0032] The fixed Lizi line is stably fixed by a bracket, while the translational Lizi line moves synchronously with the corresponding track, ensuring that the Lizi line and track position are always matched. The Lizi line structure with full track coverage provides a continuous foundation for the robot to wirelessly draw power during straight track, curved track, and switching processes, avoiding power blind spots.

[0033] The power supply component includes an E-type power collector 2 and a power rectifier 5. One end of the E-type power collector 2 is connected to the external track robot, and the other end can cooperate with the fixed straight rail Lizi line I 3, fixed curved rail Lizi line 11, fixed straight rail Lizi line II 13, fixed straight rail Lizi line III 19, translational straight rail Lizi line 15, and translational curved rail Lizi line 17 in the Lizi line structure to obtain electrical energy through electromagnetic induction. The input terminal of the power rectifier 5 is electrically connected to the E-type power collector 2, and the output terminal is electrically connected to the external track robot and the translation drive component, respectively, to rectify the induced power into stable DC power and ensure the continuity of power supply.

[0034] The E-type power take-off unit 2 can be used with all LiZI cables to draw power. The power take-off rectifier 5 converts the induced current into stable DC power, ensuring continuous power supply for the robot's translational drive. It eliminates the need for wired power supply, avoiding issues such as dragging wires and interface wear, and reducing the probability of downtime due to power supply component failures.

[0035] The translation drive assembly includes a driving translation linear module 6 and a translation platform 7. The driving translation linear module 6 is fixed to the top of the base plate 4 of the support assembly and is driven by a V DC servo motor. The translation platform 7 is fixedly connected to the moving end of the driving translation linear module 6. The translation straight rail I14 and the translation curved rail I8 are both fixed to the top of the translation platform 7. The translation platform 7 is connected to the translation straight rail Lizi line 15 through the Lizi wire groove bracket 16. The driving translation linear module 6 can drive the translation platform 7 and the translation straight rail I14 and the translation curved rail I8 above it to move back and forth, realizing track docking and switching.

[0036] A 24V DC servo motor drives the translation platform 7, which can precisely move the translation straight rail I14 / translation curved rail I8, achieving efficient track switching. The translation platform 7 integrates the translation straight rail and the translation curved rail, and is linked with the translation Lizi line to ensure that the power supply line is synchronized during track switching, avoiding coordination errors.

[0037] The DC servo motor driving the translation linear module 6 is equipped with a position sensor. The position sensor is electrically connected to the external control system and can detect the position information of the translation platform 7 in real time and feed the information back to the external control system to achieve precise control of the position of the translation platform 7, ensuring the docking accuracy of the translation straight rail I14 with the straight rail running track I1 and the straight rail running track II12, and ensuring the docking accuracy of the translation curved rail I8 with the fixed curved rail I9.

[0038] Position sensors monitor the position of the translation platform 7 in real time and feed it back to the control system, enabling precise control of the platform's position and ensuring track docking accuracy. Precise position control avoids the risk of robot misalignment due to track docking deviations, further improving the reliability of the track changer operation.

[0039] At least one leveling foot is evenly provided around the bottom of the base plate 4; each leveling foot includes a screw and a foot pad, one end of the screw is threaded to the bottom of the base plate 4, and the other end is fixedly connected to the foot pad; by rotating the screw, the horizontal height of the base plate 4 can be adjusted so that the horizontal error of the entire track changer is ≤0.05mm, ensuring the horizontal layout of the straight track I1, the straight track II12, the translational straight track I14, the fixed curved track I9, and the translational curved track I8 and the smooth operation of the robot.

[0040] The rotating screw can adjust the horizontal height of the base plate 4, ensuring that the levelness error of the track changer is ≤0.05mm, thus guaranteeing that all tracks are laid out horizontally. Horizontal tracks prevent the robot from experiencing additional stress due to track tilt, ensuring stable robot operation from the installation reference level and reducing energy consumption.

[0041] This wireless power supply translation track converter uses a support component as its installation base. Through the translation drive component, it drives the translation platform 7 and the movable tracks (translation straight track I14 and translation curved track I8) above it to move, realizing the switching and docking of the straight track structure and the curved track structure, thereby changing the robot's running direction. In the power supply component, the Lizi line structure is arranged corresponding to the track component (the fixed Lizi line is fixed to the base plate 4, and the translation Lizi line moves synchronously with the movable track). The E-type power collector 2 on the robot works with the Lizi line to draw power through electromagnetic induction, and then the power rectifier 5 converts it into stable DC power to power the robot and the translation drive component. At the same time, the position sensor and the leveling support feet respectively ensure the track docking accuracy and overall levelness, ensuring the stable operation of the equipment.

[0042] In existing technologies, the track changer and wireless power supply lines are designed independently, which can easily lead to power outages when the robot moves along the track. Furthermore, relying on wired power supply results in issues such as wire dragging and interface wear. This track changer deeply integrates track switching with wireless power supply. The Lizi line moves synchronously with the track and covers the entire track. The E-type power supply unit 2 can be adapted to draw power from all Lizi lines, achieving continuous power supply for the robot throughout its track movement. At the same time, it eliminates the need for wired power supply components, reduces the probability of failure, and meets the continuous operation requirements of intelligent logistics.

[0043] Existing technologies present significant challenges in the overall bending and processing of tracks, making it difficult to control torsion and perpendicularity. Large gaps at the joints also lead to severe vibrations as the robot moves along the track. This track changer utilizes a split track and high-precision CNC machining, coupled with position sensors to precisely control track docking, significantly improving track accuracy and docking stability. Minimal track joint gaps and leveling feet ensuring a horizontal baseline significantly reduce robot vibrations, preventing component wear and material damage, thus meeting the requirements of high-precision intelligent logistics scenarios. Furthermore, the detachable curved track bracket 10 reduces maintenance difficulty and cost.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
