Description

Technical Field

[0001] This utility model relates to the field of AGV docking platform technology, and in particular to an automatic correction device for AGV docking platform trays. Background Technology

[0002] In the fields of modern intelligent manufacturing and logistics warehousing, automated guided vehicles (AGVs) and their supporting docking stations have become key equipment for realizing automated material transfer. In actual operation, multiple layers of pallets are usually stacked on the docking station by robotic arms such as overhead cranes, and then transported away by AGV docking vehicles.

[0003] However, in the existing technology, during the pallet transportation and hoisting to the transfer platform, relative displacement and misalignment between the pallets of each layer are very likely to occur. If this is not corrected, it will not only affect the stability of subsequent AGV grabbing and transportation, but may also cause the pallets to tilt or even collapse during the transfer due to an unstable center of gravity, posing serious safety hazards and affecting the overall logistics efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic AGV docking platform pallet correction device, which solves the technical problem that existing technologies are prone to relative displacement and misalignment between pallets during pallet transportation and hoisting to the docking platform, posing safety hazards. It has the advantages of being able to automatically and efficiently perform multi-directional synchronous correction of multiple pallets and automatically reset after correction is completed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic tray correction device for AGV docking platforms, including symmetrically arranged docking platforms, a lifting block at the upper end of the docking platform, a ball bearing at the upper end of the lifting block, a drive cylinder between the lifting block and the docking platform, a primary correction mechanism and a secondary correction mechanism on the outer side of the docking platform. After the robot arm places the multi-layer trays on the docking platform, the primary correction mechanism and the secondary correction mechanism will automatically correct the position of the trays, making them neatly stacked together, thereby preventing the docking vehicle from falling off during the transfer of trays. The primary correction mechanism includes a mounting base, which is fixedly installed on the ground. A lifting bracket is movably installed on the mounting base. A hydraulic push rod is provided between the lifting bracket and the mounting base. A fixing plate is fixedly installed on the lifting bracket. Abutment plates are respectively provided at both ends of the lifting bracket. A first pressure plate is movably installed on the abutment plate. A first screw assembly for driving the first pressure plate to move is provided on the outer side of the abutment plate. The abutment plate can move up and down with the lifting bracket and also move along the length direction of the lifting bracket.

[0006] Preferably, the first screw assembly includes a first screw movably mounted on the abutment plate, a first gear fixedly mounted at the end of the first screw, and the first screw threadedly engaging with the first pressure plate. When the first screw rotates, it causes the first pressure plate to move along the width direction of the lifting bracket.

[0007] Preferably, a vertical rack is provided on one side of the first screw assembly. The vertical rack is fixedly installed on the ground and meshes with the first gear. When the lifting bracket moves upward, the first gear will rotate under the action of the vertical rack, thereby causing the first screw to rotate synchronously.

[0008] Preferably, a drive mechanism is provided on the outer side of the lifting bracket. The drive mechanism includes a drive motor fixedly installed on the lifting bracket. The output end of the drive motor is connected to a drive screw. The drive screw is threadedly engaged with the abutment plate. When the drive screw rotates, it will cause the abutment plate to move along the length direction of the lifting bracket.

[0009] Preferably, the secondary correction mechanism includes a second pressure plate movably mounted on the lifting bracket, a second screw assembly provided on the fixed plate, and a transmission rack fixedly mounted on the abutment plate. The second pressure plate can move toward another docking platform under the drive of the second screw assembly.

[0010] Preferably, the second screw assembly includes a second screw movably mounted on a fixed plate, the second screw being threadedly engaged with a second pressure plate, and a second gear fixedly mounted at the end of the second screw, the second gear meshing with a transmission rack. When the abutment plate moves, the transmission rack moves synchronously, and when the transmission rack moves, the second pressure plate moves toward the tray.

[0011] By means of the above technical solution, this utility model provides an automatic correction device for AGV docking platform pallets, which has at least the following beneficial effects: 1. By setting up a primary correction mechanism and a secondary correction mechanism, this utility model can automatically drive the first and second pressure plates to correct the position of the multi-layer pallets during the lifting support's ascent. This can effectively prevent the risk of tilting or collapse of the pallets due to misalignment. Furthermore, after the correction is completed, the first and second pressure plates will automatically reset, leaving a passage for the AGV shuttle vehicle, which significantly improves operational safety and site space utilization efficiency.

[0012] 2. By setting up a lifting block, this utility model can lift the entire pallet during the straightening process, separating it from the surface of the connecting platform. This significantly reduces friction during position adjustment, minimizing scratches and wear between the pallet and the connecting platform. It protects both the pallet and the equipment surface and makes the straightening process smoother and more stable. It is especially suitable for batch sorting operations of multi-layer stacked pallets. Attached Figure Description

[0015] 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.

[0016] Example 1 In existing technologies, during pallet transportation and hoisting to the transfer platform 1, relative displacement and misalignment between pallets are highly likely to occur. If this is not corrected, it will not only affect the stability of subsequent AGV grasping and transportation, but may also cause pallets to tilt or even collapse during transfer due to an unstable center of gravity, posing serious safety hazards and impacting overall logistics efficiency. To address this technical deficiency in existing technologies, such as... Figures 1-4As shown in the figure, this embodiment proposes an automatic AGV docking platform pallet straightening device, which can automatically and efficiently straighten multi-layer pallets in multiple directions synchronously, and automatically reset after straightening to make way for AGV docking vehicles. The device includes a docking platform 1 arranged symmetrically, a lifting block 2 is provided at the upper end of the docking platform 1, a ball bearing is provided at the upper end of the lifting block 2, and a drive cylinder is provided between the lifting block 2 and the docking platform 1. A primary correction mechanism 3 and a secondary correction mechanism 4 are provided on the outer side of the docking platform 1. After the robot arm places the multi-layer pallet on the docking platform 1, the primary correction mechanism 3 and the secondary correction mechanism 4 will automatically straighten the position of the pallet so that it is neatly stacked together, thereby preventing the docking vehicle from falling off during the transfer of the pallet.

[0017] Specifically, the first-level correction mechanism 3 includes a mounting base 301, which is fixedly installed on the ground. A lifting bracket 302 is movably mounted on the mounting base 301. A hydraulic push rod 303 is provided between the lifting bracket 302 and the mounting base 301. A fixing plate 304 is fixedly mounted on the lifting bracket 302. Abutment plates 305 are respectively provided at both ends of the lifting bracket 302. A first pressure plate 306 is movably mounted on the abutment plate 305. A first screw assembly 307 for driving the first pressure plate 306 to move is provided on the outer side of the abutment plate 305. The abutment plate 305 can move up and down with the lifting bracket 302 and can also move along the length of the lifting bracket 302. The first screw assembly 307 includes a first screw movably mounted on the abutment plate 305. A first gear is fixedly mounted at the end of the first screw. The first screw is threadedly engaged with the first pressure plate 306. When the first screw rotates, it causes the first pressure plate 306 to move along the width direction of the lifting bracket 302. A vertical toothed rod 308 is provided on one side of the first screw assembly 307. The vertical toothed rod 308 is fixedly installed on the ground and meshes with the first gear. When the lifting bracket 302 moves upward, the first gear will rotate under the action of the vertical toothed rod 308, thereby causing the first screw to rotate synchronously. A drive mechanism 309 is provided on the outer side of the lifting bracket 302. The drive mechanism 309 includes a drive motor fixedly installed on the lifting bracket 302. The output end of the drive motor is connected to a drive screw. The drive screw is threadedly engaged with the abutment plate 305. When the drive screw rotates, it causes the abutment plate 305 to move along the length direction of the lifting bracket 302.

[0018] Specifically, the secondary correction mechanism 4 includes a second pressure plate 401 movably mounted on the lifting bracket 302, a second screw assembly 402 disposed on the fixed plate 304, and a transmission rack 403 fixedly mounted on the abutment plate 305. The second pressure plate 401 can move towards another docking platform 1 under the drive of the second screw assembly 402. The second screw assembly 402 includes a second screw movably mounted on the fixed plate 304. The second screw is threadedly engaged with the second pressure plate 401. A second gear is fixedly mounted at the end of the second screw. The second gear meshes with the transmission rack 403. When the abutment plate 305 moves, it will cause the transmission rack 403 to move synchronously. When the transmission rack 403 moves, it will cause the second pressure plate 401 to move towards the tray.

[0019] Based on the above, it can be seen that, Figure 1 As shown, the area between the two docking stations 1 is the AGV channel for AGV shuttle vehicles to pass through. During the warehousing and transportation process, the robotic arm will lift multiple empty pallets onto docking station 1 in sequence. Then, the shuttle vehicle will move into the AGV channel to transport the stacked pallets away.

[0020] After multiple pallets are stacked on the connecting platform 1, the lifting bracket 302 will first move upward under the action of the hydraulic push rod 303 until the upper end of the lifting bracket 302 is flush with the uppermost pallet. When the lifting bracket 302 moves upward, the first gear will rotate under the action of the vertical rack 308, so that the first pressure plate 306 extends towards the AGV channel under the drive of the first screw. At this time, the symmetrically arranged first pressure plates 306 will be located on the left and right sides of the pallet respectively.

[0021] At the same time, the lifting block 2 will move upward under the action of the drive cylinder, thereby separating the bottom of the tray from the docking platform 1. At this time, the bottom of the tray will contact the ball bearings on the lifting block 2, which can effectively reduce the friction during the position correction process.

[0022] Next, the drive screw will rotate under the action of the drive motor, so that the abutment plate 305 moves along the length of the lifting bracket 302. When the abutment plate 305 moves, the first pressure plate 306 will move synchronously. When the two sets of first pressure plates 306 move synchronously, the position of the left and right sides of the pallet will be corrected, so that the left and right sides of the pallet are aligned.

[0023] Furthermore, when the abutment plate 305 moves, it will cause the transmission rack 403 to move synchronously. When the transmission rack 403 moves, it will cause the second screw to rotate around its own axis through the cooperation with the second gear. When the second screw rotates, it will cause the second pressure plate 401 to move towards the pallet. When the second pressure plates 401 on the two docking platforms 1 approach each other, they will correct the position of the front and rear sides of the pallet, thereby aligning the front and rear sides of the pallet.

[0024] After the action is completed, the abutment plate 305 will be reset under the drive of the drive screw. During the reset process of the abutment plate 305, the first pressure plate 306 and the second pressure plate 401 will be separated from the tray. Subsequently, the lifting bracket 302 will move downward under the action of the hydraulic push rod 303. During this process, the first pressure plate 306 will be moved out of the AGV channel under the drive of the first screw.

[0025] Then, the shuttle vehicle will drive into the AGV channel to remove the neatly stacked pallets.

[0026] This embodiment, by setting up a primary correction mechanism 3 and a secondary correction mechanism 4, enables the lifting support 302 to automatically drive the first pressure plate 306 and the second pressure plate 401 to correct the position of the multi-layer pallets during the upward movement. This effectively prevents the risk of tilting or collapse of the pallets due to misalignment. Furthermore, after correction, the first pressure plate 306 and the second pressure plate 401 will automatically reset, leaving a passage for the AGV shuttle vehicle, significantly improving operational safety and site space utilization efficiency. In addition, by setting up the lifting block 2, this embodiment can lift the entire pallet during the correction process, separating it from the surface of the connecting platform 1. This significantly reduces friction during position adjustment, reducing scratches and wear between the pallet and the connecting platform 1, protecting the pallet and equipment surfaces, and making the correction process smoother and more stable. This is especially suitable for batch sorting operations of multi-layer stacked pallets.

The power supply is also common knowledge in the field.
