[0001] This utility model belongs to the field of AGV robot technology, specifically a warehouse AGV robot lifting platform. Background Technology

[0002] In modern warehousing and logistics systems, AGV robots are widely used for tasks such as material handling, goods storage, and retrieval. Traditional AGV robots are typically equipped with simple lifting mechanisms for moving pallets or goods.

[0003] In the prior art, the lifting platform of a robot is generally of fixed width. When transferring boxes with a larger width, it cannot provide sufficient support area, which limits the versatility and flexibility of the robot. Different robots are required, which increases the complexity and cost of the warehousing and logistics system. Therefore, this utility model provides a lifting platform for a warehousing AGV robot. Utility Model Content

[0004] To compensate for the shortcomings of existing technologies, robot lifting platforms are generally of fixed width. When transferring boxes with larger widths, they cannot provide sufficient support area, which limits the versatility and flexibility of robots. Different robots are required, which increases the complexity and cost of warehousing and logistics systems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A lifting platform for a warehouse AGV robot, comprising a robot body, a lifting platform mechanism disposed on the top of the robot body, and the lifting platform mechanism comprising:

[0006] The support assembly includes a support plate fixed to the top of the robot body, rectangular grooves on both sides of the support plate, a sliding plate slidably connected in the rectangular grooves, a fixed plate fixed to the side wall of the sliding plate away from the support plate, an L-shaped plate fixed to the bottom of the support plate, and a mounting plate fixed to the top of the L-shaped plate laterally. The mounting plate is provided with a pushing assembly for moving a pair of fixed plates.

[0007] A protective component is installed on top of the support plate to protect the placed box.

[0008] Preferably, the pushing assembly includes a driving unit and a sliding rod rotatably connected to the side wall of the fixed plate via a first rotating shaft. A pair of concave blocks are fixed to the side wall of the support plate. The sliding rod is slidably connected between the opposite side walls of the concave blocks. An adjusting rod is rotatably connected to the side wall of the sliding rod away from the fixed plate via a second rotating shaft.

[0009] Preferably, the drive unit includes a servo motor fixed to the side wall of the mounting plate, the output end of the servo motor is provided with a drive rod, the end of the drive rod away from the servo motor is fixed to a rotating rod, and the side wall of the adjusting rod away from the sliding rod is rotatably connected to the side wall of the rotating rod through a third rotating shaft.

[0010] Preferably, the protective assembly includes a pressing unit, a rotating unit, and a pair of fixed blocks fixed to the side wall of a fixed plate. A circular rod is rotatably connected between the opposite side walls of the pair of fixed blocks. One end of the circular rod passes through one of the fixed blocks, and the end of the circular rod away from the servo motor is fixed to a protective plate.

[0011] Preferably, the rotating unit includes a convex groove on a fixed plate, a sliding block is slidably connected in the convex groove, a rack is fixedly connected to the bottom of the sliding block, and a pair of gears are fixedly connected to the circular rod, the gears meshing with the rack.

[0012] Preferably, the extrusion unit includes a square block fixed to the top of the sliding block, the square block being connected to a fixed plate via a spring, and an extrusion plate being fixed to a pair of the side walls of the sliding block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The warehouse AGV robot lifting platform described in this utility model can expand the placement width of the robot top and increase the placement area by unfolding a pair of sliding plates and a pair of fixed plates driven by a pushing component. This solves the problem in the prior art where the robot lifting platform is generally of fixed width, which cannot provide sufficient support area when transferring boxes with larger widths, thus limiting the robot's versatility and flexibility, requiring the use of different robots, and increasing the complexity and cost of the warehousing and logistics system.

[0015] 2. The warehouse AGV robot lifting platform of this utility model, by setting a square block connected to a fixed plate by a spring, allows the box to be clamped by a pair of fixed plates while the box is pressed against the compression plate. This causes the sliding block to move, which in turn causes the rack connected to the gear to rotate. This causes the protective plate fixed to the circular rod to rotate, thus protecting the front of the box and preventing it from falling due to inertia if the robot suddenly stops moving. After the transfer is completed, the spring returns to its original position. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown in the figure, a warehouse AGV robot lifting platform according to an embodiment of the present invention includes a robot body 1, a lifting platform mechanism provided on the top of the robot body 1, and the lifting platform mechanism including: a support assembly including a support plate 2 fixedly connected to the top of the robot body 1, rectangular grooves 3 opened on both sides of the support plate 2, a sliding plate 4 slidably connected in the rectangular grooves 3, a fixing plate 5 fixedly connected to the side wall of the sliding plate 4 away from the support plate 2, an L-shaped plate 6 fixedly connected to the bottom of the support plate 2, a mounting plate 7 fixedly connected to the top of the L-shaped plate 6 laterally, and a pushing assembly for driving a pair of fixing plates 5 to move on the mounting plate 7; and a protective assembly provided on the top of the support plate 2 for protecting the placed box.

[0025] During operation, the pair of sliding plates 4 and the pair of fixed plates 5 can be deployed under the drive of the pushing component, thereby expanding the placement width of the robot top and increasing the placement area. This solves the problem in the existing technology where the robot's lifting platform is generally of fixed width, which cannot provide sufficient support area when transferring larger boxes, thus limiting the robot's versatility and flexibility, requiring the use of different robots, and increasing the complexity and cost of the warehousing and logistics system.

[0026] The pushing assembly includes a drive unit and a sliding rod 8 rotatably connected to the side wall of the fixed plate 5 via a first rotating shaft. A pair of concave blocks 9 are fixed to the side wall of the support plate 2. The sliding rod 8 is slidably connected between the opposite side walls of the concave blocks 9. An adjusting rod 10 is rotatably connected to the side wall of the sliding rod 8 away from the fixed plate 5 via a second rotating shaft.

[0027] The drive unit includes a servo motor 11 fixed to the side wall of the mounting plate 7. The output end of the servo motor 11 is provided with a drive rod 12. The end of the drive rod 12 away from the servo motor 11 is fixed to a rotating rod 13. The side wall of the adjusting rod 10 away from the sliding rod 8 is rotatably connected to the side wall of the rotating rod 13 through a third rotating shaft.

[0028] During operation, the servo motor 11 drives the rotating rod 13 to rotate, so that the rotating rod 13 can push the sliding rod 8 to slide inside the concave block 9 through the adjusting rod 10, thereby pushing the fixed plate 5 to move and increase the placement width. After the box is placed, the servo motor 11 reverses to perform a certain degree of clamping and fixing, improving the stability during the transfer process.

[0029] The protective assembly includes a pressing unit, a rotating unit, and a pair of fixed blocks 14 fixed to the side wall of a fixed plate 5. A circular rod 15 is rotatably connected between the opposite side walls of the pair of fixed blocks 14. One end of the circular rod 15 passes through one of the fixed blocks 14, and a protective plate 16 is fixed to the end of the circular rod 15 away from the servo motor 11.

[0030] The rotating unit includes a convex groove 17 on the fixed plate 5, a sliding block 18 is slidably connected in the convex groove 17, a rack 19 is fixedly connected to the bottom of the sliding block 18, and a pair of gears 20 are fixedly connected to the circular rod 15, and the gears 20 are meshed with the rack 19.

[0031] The extrusion unit includes a square block 21 fixed to the top of the sliding block 18. The square block 21 is connected to the fixed plate 5 by a spring 22. An extrusion plate 23 is fixed to the side wall of a pair of sliding blocks 18.

[0032] During operation, the square block 21 is connected to the fixed plate 5 via the spring 22. When the fixed plate 5 clamps the placed box, the placed box simultaneously presses against the compression plate 23, causing the sliding block 18 to move. This allows the rack 19, which meshes with the gear 20, to drive the gear 20 to rotate, causing the protective plate 16, which is fixed to the circular rod 15, to rotate. This protects the front of the placed box and prevents it from falling due to inertia if the robot body 1 suddenly stops moving during the movement. After the transfer is completed, the spring 22 returns to its original position.

[0033] Working principle: The robot's top width is expanded by the unfolding of a pair of sliding plates 4 and a pair of fixed plates 5 driven by the push component, thereby increasing the placement area. This solves the problem that in the existing technology, the robot's lifting platform is generally of fixed width, which cannot provide sufficient support area when transferring boxes with larger widths. This limits the robot's versatility and flexibility, requires the use of different robots, and increases the complexity and cost of the warehousing and logistics system.

[0034] The servo motor 11 drives the rotating rod 13 to rotate, so that the rotating rod 13 can push the sliding rod 8 to slide inside the concave block 9 through the adjusting rod 10, thereby pushing the fixed plate 5 to move and increase the placement width. After the box is placed, the servo motor 11 reverses to perform a certain degree of clamping and fixing, improving the stability during the transfer process.

[0035] By connecting the square block 21 to the fixed plate 5 via the spring 22, when the fixed plate 5 clamps the placed box, the placed box simultaneously presses against the compression plate 23, causing the sliding block 18 to move. This allows the rack 19, which meshes with the gear 20, to drive the gear 20 to rotate, causing the protective plate 16, which is fixed to the circular rod 15, to rotate. This protects the front of the placed box, preventing it from falling due to inertia if the robot body 1 suddenly stops moving during the movement. The protective plate 16 prevents the placed box from falling, and after the transfer is completed, the spring 22 rebounds.
