Description

Technical Field

[0001] This utility model relates to the field of transfer robot technology, and in particular to an Internet-based logistics transfer robot. Background Technology

[0002] Logistics transfer robots are robots used in warehouses, sorting centers, and during transportation to perform operations such as transferring and handling goods. These robots typically possess functions such as autonomous navigation, automatic obstacle avoidance, and intelligent scheduling, enabling them to transport goods from the origin to the destination according to predetermined routes or instructions. Depending on their functions and application scenarios, logistics transfer robots can be categorized into various types, such as AGVs (Automated Guided Vehicles), AMRs (Autonomous Mobile Robots), and collaborative robotic arms. Internet-based logistics transfer robots are an important component of modern logistics systems. Through internet technology and intelligent navigation systems, they achieve efficient and automated transfer of goods in warehouses, sorting centers, and during transportation. Logistics transfer robots are widely used in e-commerce warehouses, manufacturing workshops, airport cargo, express sorting centers, and other scenarios. They can replace manual labor in completing tedious and repetitive handling tasks, improving logistics efficiency and service quality.

[0003] A handling robot for a warehousing and logistics system, disclosed in Chinese patent document CN108529483A, includes a vehicle body comprising a base plate and driving and driven wheels mounted on the base plate. The vehicle body is equipped with a lifting and rotating unit and an environmental detection unit. The lifting and rotating unit includes a lifting platform with a rotating pallet controllably rotating relative to it. The lifting and rotating unit also includes at least one set of drive components for raising and lowering the lifting platform. This warehousing and logistics system handling robot of the present invention achieves the raising and lowering of the rotating pallet through the cooperation of the lifting surface on the lifting block and the cam pair of the cam follower, and achieves the rotation of the rotating pallet through the meshing of a large gear and a small gear. The structure is stable and reliable, enabling the handling of goods on shelves and suitable for large-scale deployment. However, the pallet size of this warehousing and logistics system handling robot is relatively small, limiting its handling capacity.

[0004] The loading and unloading of goods by existing logistics transfer robots takes a long time, which affects the transfer efficiency of the robots.

[0005] To address the shortcomings of the existing technologies, providing an internet-based logistics transfer robot is a worthwhile research topic. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing logistics transfer robots, which require a lot of time for loading and unloading goods during the handling process, thus affecting the robot's transfer efficiency. This invention provides an Internet-based logistics transfer robot that achieves efficient loading, unloading, and transfer.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An internet-based logistics transfer robot includes a transfer frame and a transfer robot disposed below the transfer frame. The transfer robot has a moving mechanism and a supporting mechanism at its bottom.

[0009] The bottom of the transfer frame is provided with a mating groove, one side of which is semi-circular and the other side of which is open and communicates with the outside.

[0010] The inner diameter of the mating groove is adapted to the diameter of the transfer robot. Anti-slip textures are provided on the inner side of the arc surface of the mating groove and the outer side of the transfer robot. The anti-slip textures can increase the friction between the two, making the two fit more tightly. When the transfer robot turns, the transfer frame can turn accordingly, avoiding insufficient friction between the two and resulting in inadequate fit.

[0011] The support mechanism includes several telescopic cylinders fixedly connected to the top of the transfer robot, and a support plate fixedly connected to the top of the output end of the telescopic cylinders.

[0012] The support plate is disc-shaped, and its diameter is adapted to the diameter of the transfer robot. When the telescopic cylinder retracts, the total height of the transfer robot and the support plate is less than the height of the mating groove. When the telescopic cylinder extends, the total height of the transfer robot and the support plate is greater than the height of the mating groove. The total support load of the telescopic cylinder is greater than the total weight of the transfer frame and the transferred material. It works in conjunction with the transfer frame to achieve rapid loading and unloading, and eliminates the process of stacking and moving goods. It is also smaller and easier to move than a forklift.

[0013] A shock-absorbing pad is fixedly connected to the top inner side of the support plate. The top height of the shock-absorbing pad is higher than the top height of the support plate. The shock-absorbing pad can play a buffering role, making the lifting and lowering of the transfer frame smoother and preventing the goods on the transfer frame from shaking and tipping over.

[0014] The moving mechanism includes drive wheels located on both sides of the bottom of the transfer robot. The drive wheels are all driven by motors. The middle and front and rear sides of the transfer robot are provided with spherical grooves, and ball bearings are rolled in the spherical grooves. The bottom heights of the drive wheels and the ball bearings are equal. The driving load of the drive wheels is greater than the total weight of the transfer frame and the transferred goods. The drive wheels at the bottom of the transfer robot drive the entire transfer robot, and even the transfer frame and the transferred goods above the transfer robot, to move and complete the transfer work.

[0015] The transfer robot has storage slots on all four sides of its bottom. An electric push rod is fixedly connected inside the storage slot. A robot vision camera is fixedly connected to the output end of the electric push rod. The robot vision camera is tilted upward and extends out of the storage slot to visually identify the situation outside and provide timely feedback to the transfer robot and control terminal. This enables Internet-based logistics robot control, allowing the robot to automatically identify the surrounding environment and perform fully automated logistics transfer.

[0016] The bottom of the left and right sides and the bottom of the rear side of the transfer frame are all provided with slots. The position of the slots corresponds to the position of the robot vision camera on the transfer robot. The width of the slots is greater than the width of the robot vision camera. When the transfer robot cooperates with the transfer frame, it can understand the external situation in a timely manner through the robot vision camera, so that the transfer robot can realize automated and safe transfer.

[0017] Positive and beneficial effects:

[0018] 1. This internet-based logistics transfer robot can work with the transfer frame to achieve rapid loading and unloading of goods, eliminating the process of stacking and moving goods, and is smaller and more convenient to move than a forklift.

[0019] 2. This internet-based logistics transfer robot uses drive wheels to move the entire robot, including the transfer frame and the goods on top of it, thus completing the transfer work. The bottom of the ball bearings can contact the ground, which increases the overall stability of the transfer robot, increases the contact area between the robot and the ground, and increases its load-bearing capacity.

[0020] 3. This internet-based logistics transfer robot has a vision camera that extends from the storage slot to visually identify the surrounding environment and provide timely feedback to the transfer robot and control terminal. This enables internet-based control of the logistics robot, allowing it to automatically identify the surrounding environment and perform fully automated logistics transfer.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] Example 1

[0034] like Figures 1 to 10 As shown, an Internet-based logistics transfer robot includes a transfer frame 1 and a transfer robot 2 disposed below the transfer frame 1. The bottom of the transfer robot 2 is provided with a moving mechanism and a supporting mechanism.

[0035] like Figures 1 to 6As shown, the bottom of the transfer frame 1 is provided with a mating groove 3. One side of the mating groove 3 is semi-circular, and the other side of the mating groove 3 is open and communicates with the outside.

[0036] The inner diameter of the mating groove 3 is adapted to the diameter of the transfer robot 2. Anti-slip textures 4 are provided on the inner side of the arc surface of the mating groove 3 and the outer side of the transfer robot 2. By setting an arc-shaped mating groove 3 with an opening at the bottom of the transfer frame 1, after the logistics materials to be transferred are placed on the transfer frame 1, the transfer robot 2 enters the interior of the mating groove 3 from the opening of the mating groove 3 and completes the mating with the mating groove 3, so that it can drive the transfer frame 1 and the logistics materials to be transferred. After reaching the transfer destination, the mating with the transfer frame 1 is contacted, and the transfer robot 2 can carry out the next transfer work, saving the loading and unloading process in the transfer process and improving the transfer efficiency.

[0037] Furthermore, anti-slip textures 2 are provided on the inner side of the mating groove 3 and the outer side of the transfer robot 2. After the two are mated, the anti-slip textures 2 can increase the friction between them, making the mating more tight. When the transfer robot 2 turns, the transfer frame 1 can turn accordingly, avoiding insufficient friction between the two leading to inadequate mating.

[0038] like Figures 7 to 10 As shown, the support mechanism includes several telescopic cylinders 5 fixedly connected to the top of the transfer robot 2, and a support plate 6 fixedly connected to the top of the output end of the telescopic cylinders 5.

[0039] The support plate 6 is disc-shaped, and its diameter matches that of the transfer robot 2. When the telescopic cylinder 5 is retracted, the total height of the transfer robot 2 and the support plate 6 is less than the height of the mating groove 3. When the telescopic cylinder 5 is extended, the total height of the transfer robot 2 and the support plate 6 is greater than the height of the mating groove 3. The total support load of the telescopic cylinder 5 is greater than the total weight of the transfer frame 1 and the transferred material. By setting a telescopic support mechanism on the top of the mobile robot 2, the telescopic cylinder 5 is in a retracted state before the transfer robot enters the mating groove 3, making the overall height of the transfer robot less than that of the mating groove 3. The height allows it to smoothly enter the interior. When the transfer robot contacts the arc surface of the mating groove 3, the telescopic cylinder 5 extends. As the height extends, it lifts the transfer frame 1 and the goods loaded on it, allowing the transfer robot to carry the goods for movement. After reaching the transfer destination, the telescopic cylinder 5 retracts again, allowing the transfer frame 1 to contact the ground. The transfer robot then exits from the opening of the mating groove 3 to begin the next transfer operation. This transfer robot can work with the transfer frame 1 to achieve rapid loading and unloading, eliminating the need for stacking and moving goods. It is also smaller and more convenient to move than a forklift.

[0040] like Figures 7 to 10As shown, a shock-absorbing pad 9 is fixedly connected to the top inner side of the support plate 6. The top height of the shock-absorbing pad 9 is higher than the top height of the support plate 6. By setting the shock-absorbing pad 9 on the top of the support plate 6, the shock-absorbing pad 9 is made of shock-absorbing sponge or air cushion. During the contact between the support plate 6 and the transfer frame 1, the shock-absorbing pad 9 can play a buffering role, making the lifting and lowering of the transfer frame 1 smoother and preventing the goods on the transfer frame 1 from shaking and tipping over.

[0041] Example 2

[0042] like Figures 8 to 10 As shown, the moving mechanism includes drive wheels 7 located on both sides of the bottom of the transfer robot 2. The drive wheels 7 are all driven by motors. The middle and front and rear sides of the transfer robot 2 are provided with spherical grooves, and ball bearings 8 are rolled in the spherical grooves. The bottom heights of the drive wheels 7 and the ball bearings 8 are equal. The driving load of the drive wheels 7 is greater than the total weight of the transfer frame 1 and the transferred goods. By setting the drive wheels 7 at the bottom of the transfer robot 2, the entire transfer robot 2, and even the transfer frame 1 and the transferred goods above the transfer robot, are moved, thereby completing the transfer work. The bottom of the ball bearings 8 can contact the ground, which increases the overall stability of the transfer robot and also increases the contact area between the transfer robot and the ground, thus increasing the load-bearing capacity.

[0043] Both the drive wheel 7 and the drive motor are electrically connected to the transfer robot 2, and the operation of the drive wheel 7 and the drive motor is controlled by the transfer robot 2.

[0044] Example 3

[0045] like Figures 3 to 10 As shown, the bottom of the transfer robot 2 has storage slots 10 on all four sides. An electric push rod 11 is fixedly connected inside the storage slot 10. A robot vision camera 12 is fixedly connected to the output end of the electric push rod 11. The robot vision camera 12 is tilted upward. By setting electric push rods 11 with vision cameras 12 on the four sides of the transfer robot 2, when the transfer robot 2 enters or leaves the transfer frame 1, the electric push rod 11 and the robot vision camera 12 retract into the storage slot 10 to avoid interference with the mating slot 3. When the transfer robot 2 is inside or outside the transfer frame 1, the robot vision camera 12 extends out of the storage slot 10 to visually identify the situation outside and promptly feed back to the transfer robot 2 and the control terminal, realizing Internet-based logistics robot control, enabling the robot to automatically identify the surrounding environment and carry out fully automated logistics transfer.

[0046] like Figure 3As shown, slots 13 are provided on the bottom of the left and right sides and the bottom of the rear side of the transfer frame 1. The position of the slots 13 corresponds to the position of the robot vision camera 12 on the transfer robot 2. The width of the slots 13 is greater than the width of the robot vision camera 12. By setting slots 13 on the transfer frame 1, the robot vision camera 12 can extend a certain distance from the slots 13, so that the transfer robot 2 can understand the external situation in a timely manner through the robot vision camera 12 when cooperating with the transfer frame 1, so that the transfer robot can realize automated and safe transfer.

[0047] The working principle of this utility model is as follows:

[0048] S1. After placing the logistics materials to be transferred on the transfer frame 1, the transfer robot 2 enters the interior of the mating groove 3 from the opening of the mating groove 3 and completes the mating with the mating groove 3. Before the transfer robot enters the mating groove 3, the telescopic cylinder 5 is in the retracted state, so that the overall height of the transfer robot is less than the height of the mating groove 3, and it can enter the interior smoothly.

[0049] S2. When the transfer robot contacts the arc surface of the mating groove 3, the telescopic cylinder 5 extends. As the height extends, it lifts the transfer frame 1 and the goods loaded on the transfer frame 1, so that the transfer robot can carry the transfer goods to move.

[0050] S3. After reaching the transfer destination, retract the telescopic cylinder 5 again to make the transfer frame 1 contact the ground. The transfer robot then exits from the opening of the mating slot 3 to carry out the next transfer operation. This transfer robot can cooperate with the transfer frame 1 to achieve rapid loading and unloading, and saves the process of stacking and moving goods. It is also smaller and more convenient to move than a forklift.

[0051] S4 and drive wheel 7 drive the entire transfer robot 2, and even the transfer frame 1 and the transferred goods on the transfer robot, to move, thereby completing the transfer work. The bottom of the ball bearing 8 can contact the ground, which increases the overall stability of the transfer robot and also increases the contact area between the transfer robot and the ground, thus increasing its load-bearing capacity.

[0052] S5. When the transfer robot 2 enters or leaves the transfer frame 1, the electric push rod 11 and the robot vision camera 12 retract into the storage slot 10 to avoid interference with the mating slot 3. When the transfer robot 2 is inside or outside the transfer frame 1, the robot vision camera 12 extends out of the storage slot 10 to visually identify the situation outside and promptly feed back to the transfer robot 2 and the control terminal to realize Internet-based logistics robot control.
