Description

Technical Field

[0001] This utility model belongs to the field of charging equipment technology, and specifically relates to a charging device for logistics robots. Background Technology

[0002] In modern automated seedling and planting systems, logistics robots play a crucial role, precisely transporting planting units, such as seedling trays, along tracks. They are key equipment for automating the entire process from seedling cultivation to vegetable planting. However, their charging process faces numerous challenges, and the limitations of existing charging devices significantly impact the efficient operation of logistics robots.

[0003] Currently, while it seems simple to charge logistics robots by adjusting their horizontal position, the actual operation is fraught with difficulties.

[0004] Traditional charging devices require extremely high horizontal alignment precision for logistics robots. Due to wear and deformation of the track over long-term use, as well as the vibrations and inertia experienced by the robot during operation, horizontal deviations are unavoidable when the robot reaches the charging position. Even extremely small horizontal deviations can prevent the charging plug from accurately aligning with the socket, thus preventing normal charging. According to relevant statistics, in some large-scale planting bases, charging failures due to horizontal positioning deviations of logistics robots occur dozens of times per week, severely impacting the continuity of planting operations, causing a significant drop in production efficiency, and resulting in delays of several hours on average per charging failure, leading to substantial economic losses in agricultural production. Utility Model Content

[0005] The purpose of this invention is to provide a charging device for logistics robots that can improve the allowable range of alignment deviation between the plug and the socket, reduce the alignment accuracy requirements of the plug, and reduce the difficulty of alignment and positioning when the logistics robot is charging.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A charging device for a logistics robot includes a charger body and an electrically controlled telescopic rod. One end of the electrically controlled telescopic rod is fixedly connected to an adaptive elastic bracket. An installation plate is fixedly connected to the adaptive elastic bracket. An annular positioning ring and a plug are fixedly connected to the installation plate. A positioning block and a socket are fixedly connected to the charger body. The socket and the charger body are electrically connected.

[0008] The positioning block has an annular positioning groove inside, and an annular flared groove connected to the annular positioning groove is formed on one side of the positioning block. The size of the annular flared groove gradually increases from the end closer to the positioning block to the end farther away from the positioning block.

[0009] Furthermore, the adaptive elastic support includes a rectangular frame installed at one end of the electrically controlled telescopic rod, a connecting block is horizontally slidably connected inside the rectangular frame, one end of the connecting block is fixedly connected to the mounting plate, and a return spring is fixedly connected to both sides of the connecting block.

[0010] Furthermore, one end of the electrically controlled telescopic rod is fixedly connected to a sphere and a side bracket, and one side of the rectangular frame is fixedly connected to a connecting ball seat. The connecting ball seat has a spherical cavity inside, and the sphere is rotatably connected inside the spherical cavity. Multiple tension springs arranged in a circular array with the connecting ball seat axis as the center are fixedly connected between the rectangular frame and the side bracket.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This utility model discloses a charging device for logistics robots. By setting up an adaptive elastic bracket, an annular positioning groove, and an annular positioning ring, the plug and socket can automatically calibrate the position of the plug within a certain deviation range. This improves the allowable range of alignment deviation between the plug and socket, reduces the alignment accuracy requirement of the plug, and reduces the difficulty of alignment and positioning during charging.

Detailed Implementation

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] Example 1:

[0021] like Figure 1 As shown, a seedling raising system includes a transverse track 3, a longitudinal track 4, a seedling tray 5, a logistics robot 6, and a lane-changing robot 7 set on a seedling raising site 1. A boundary 2 is set around the seedling raising site 1.

[0022] The seedling nursery is divided into multiple seedling zones arranged along the X-axis. The long side of each seedling zone is set along the Y-axis. The multiple seedling zones are named sequentially from left to right as Zone 1, Zone 2, Zone 3, ..., Zone N.

[0023] There are several seedling trays 5, and each seedling tray 5 is fixedly connected to any one of the seedling sections.

[0024] There are multiple longitudinal tracks 4, which are arranged side by side. The long side of the multiple longitudinal tracks 4 is set along the Y-axis, so that the multiple longitudinal tracks 4 are fixedly connected to multiple seedling sections. The multiple longitudinal tracks 4 are named in order from left to right as first longitudinal track, second longitudinal track, third longitudinal track, ..., Nth longitudinal track.

[0025] There is at least one logistics robot 6. The logistics robot 6 is installed on the longitudinal track 4 and can move on the longitudinal track 4. The logistics robot 6 can carry the seedling tray 5 and move the seedling tray 5 to complete the transportation of the seedling tray 5.

[0026] Specifically, the seedling tray 5 has protruding pillars on its side, and the logistics robot 6 is equipped with a lifting device with hooks. When the hooks hook onto the protruding pillars, the lifting device is activated to lift the seedling tray 5. When the seedling tray 5 is raised, it can be moved by the logistics robot 6. After the logistics robot 6 has moved, the lifting device can be activated to lower the seedling tray 5 and place it in the set position.

[0027] The transverse track 3 is fixedly connected to the upper side of the seedling site 1 at one end of multiple longitudinal tracks 4. The long side of the transverse track 3 is set along the X-axis. The lane-changing robot 7 is installed on the upper side of the transverse track 3. The logistics robot 6 can move onto the lane-changing robot 7. At this time, the lane-changing robot 7 drives the logistics robot 6 to move to a position opposite to another longitudinal track 4. Then, the logistics robot 6 on the lane-changing robot 7 moves onto the longitudinal track 4, thus completing the lane change of the logistics robot 6.

[0028] Specifically, when the logistics robot 6 moves the seedling tray 5 along different longitudinal tracks 4, assuming the logistics robot 6 is in the first longitudinal track and needs to move to the fourth longitudinal track, when the logistics robot 6 moves to a position close to the transverse track 3 on the first longitudinal track, the lane-changing robot 7 arrives at the first longitudinal track. Then, the logistics robot 6 moves above the lane-changing robot 7, and the lane-changing robot 7 moves the logistics robot 6 to the fourth longitudinal track. The logistics robot 6 leaves the lane-changing robot 7 and enters the fourth longitudinal track, thus completing the lane change of the logistics robot 6. Then, the logistics robot 6 moves the seedling tray 5 on the logistics robot 6 to the set position. In this way, the movement of the seedling tray 5 can be completed by replacing manual labor with automated equipment, which greatly reduces labor costs.

[0029] Example 2:

[0030] like Figures 1-4 As shown, a charging device for a logistics robot includes a charger body 27 and an electrically controlled telescopic rod 8. The charger body 27 is fixedly connected to the upper side of the seedling site 1 and located on one side of the transverse track 3. The electrically controlled telescopic rod 8 is fixedly connected to the outside of the logistics robot 6. One end of the electrically controlled telescopic rod 8 is fixedly connected to an adaptive elastic bracket. An installation plate 17 is fixedly connected to the adaptive elastic bracket. An annular positioning ring 18 and a plug 22 are fixedly connected to the installation plate 17. A positioning block 19 and a socket 23 are fixedly connected to the charger body 27. The plug 22 is electrically connected to the battery of the logistics robot 6, and the socket 23 is electrically connected to the charger body 27. When the plug 22 is inserted into the socket 23, the battery of the logistics robot 6 can be charged through the charger body 27.

[0031] The positioning block 19 has an annular positioning groove 20 inside, and an annular flared groove 21 connected to the annular positioning groove 20 is opened on one side of the positioning block 19. The size of the annular flared groove 21 gradually increases from the end near the positioning block 19 to the end away from the positioning block 19. When the logistics robot 6 is moved by the lane-changing robot 7 to a position opposite to the charger body 27, the electric telescopic rod 8 is activated to drive the annular positioning ring 18 and the plug 22 to move towards the charger body 27. When the annular positioning ring 18 is directly aligned with the annular positioning groove 20, it can move directly into the annular positioning groove 20. When there is a certain overlap between the annular positioning ring 18 and the annular positioning groove 20, and the annular positioning ring 18 and the annular flared groove 21 are directly aligned, the setting of the adaptive elastic bracket allows the annular positioning ring 18 to make a certain horizontal displacement on the electric telescopic rod 8. When the plug 22 and the annular flared groove 21 are abutted, the plug 22 can slide into the annular positioning groove 20 along the inclined surface of the annular flared groove 21, thereby completing the horizontal calibration of the annular positioning ring 18. Since the annular positioning ring 18 and the plug 22 are both fixedly connected to the same mounting plate 17, after the annular positioning ring 18 is horizontally calibrated, the plug 22 and the socket 23 are aligned. At this time, the plug 22 is moved towards the charger body 27 by the electric telescopic rod 8, so that the plug 22 can be accurately inserted into the socket 23. Thus, through the setting of the adaptive elastic bracket, the annular positioning groove 20 and the annular positioning ring 18, the position of the plug 22 can be automatically calibrated within a certain deviation range, thereby improving the allowable range of alignment deviation between the plug 22 and the socket 23, reducing the alignment accuracy requirement of the plug 22, reducing the difficulty of alignment and positioning during charging, and the structure is relatively simple.

[0032] The aforementioned deviation range is the area between the annular positioning groove 20 and the annular flared groove 21.

[0033] Among them, the electrically controlled telescopic rod 8 can be an electric push rod, hydraulic cylinder or other equipment that can drive the adaptive elastic support to move linearly.

[0034] Among them, such as Figures 2-4 As shown, the adaptive elastic support includes a rectangular frame 11 installed at one end of the electrically controlled telescopic rod 8. A connecting block 12 is horizontally slidably connected inside the rectangular frame 11. One end of the connecting block 12 is fixedly connected to the mounting plate 17. At this time, the mounting plate 17 can be moved horizontally by the horizontal movement of the connecting block 12 inside the rectangular frame 11. Return springs 13 are fixedly connected to both sides of the connecting block 12. The two return springs 13 can initially position the connecting block 12, positioning the initial position of the connecting block 12 at the middle position of the rectangular frame 11.

[0035] Meanwhile, pressure plates 15 are slidably connected inside the rectangular frame 11 and on both sides of the connecting block 12. The end of the return spring 13 away from the connecting block 12 is fixedly connected to the pressure plate 15. Both ends of the rectangular frame 11 are rotatably connected to screws 14, which are threadedly connected to the pressure plates 15. At this time, by rotating the screws 14, the pressure plates 15 can be moved, adjusting the pressure applied by the pressure plates 15 to the rectangular frame 11, thereby adjusting the sensitivity of the connecting block 12 to move under force.

[0036] like Figure 2 and Figure 4 As shown, an indicator needle 16 extending to the outside of a rectangular frame 11 is fixedly connected to the outside of the pressure plate 15. A scale 26 is provided on the outside of the rectangular frame 11. By observing the position pointed to by the indicator needle 16 on the scale 26, the user can easily determine the position of the pressure plate 15.

[0037] The rectangular frame 11 can be directly fixed to the electrically controlled telescopic rod 8, or it can be... Figure 4 As shown, a sphere 9 and a side bracket 24 are fixedly connected to one end of the electrically controlled telescopic rod 8. A connecting ball seat 10 is fixedly connected to one side of the rectangular frame 11. The connecting ball seat 10 has a spherical cavity with one side open, and the opening diameter of the spherical cavity is smaller than the maximum diameter of the spherical cavity. The sphere 9 is directly rotatably connected to the inside of the spherical cavity, so that the connecting ball seat 10 can rotate in multiple directions outside the sphere 9. Multiple tension springs 25 are fixedly connected between the rectangular frame 11 and the side bracket 24 in a circular array with the axis of the connecting ball seat 10 as the center. At this time, the arrangement of the sphere 9 and the tension springs 25 allows the rectangular frame 11 to rotate at a certain angle, which better adapts to the error between the plug 22 and the socket 23.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
