[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a stacker crane for an automated warehouse, such as... Figures 1 to 7 As shown, two ground rails 2 are fixedly connected to the upper surface of the base plate 1. An electric control slide plate 3 is slidably connected to the outer ring of the ground rails 2. A fixed frame 4 is set above the base plate 1. A movable frame 5 is slidably connected to the inner cavity of the fixed frame 4. A placement groove 6 is opened on one side of the movable frame 5. An air pump 18 is fixedly installed at the bottom of the inner cavity of the placement groove 6. A double pipe 19 is fixedly connected to one end of the air pump 18. Two suction plates 13 are set in the inner cavity of the movable frame 5. A limit groove 9 is opened at the bottom of the inner cavity of the movable frame 5. A folded hose 20 is fixedly connected to one end of the double pipe 19 through the inner cavity of the limit groove 9.

[0027] The top of the electric sliding plate 3 is fixedly connected to the bottom of the fixed frame 4. The inner walls on both sides of the fixed frame 4 are provided with sliding grooves 7. The inner cavity of the sliding groove 7 is slidably connected to the slider 8. The top of the inner cavity of the sliding groove 7 is fixedly installed with a first electric push rod 14. The output end of the first electric push rod 14 is fixedly connected to one side of the corresponding slider 8. When the stacker crane is handling goods, the first electric push rod 14 can be controlled by the synchronous controller to push the slider 8 to slide up and down in the sliding groove 7, thereby driving the moving frame 5 to achieve vertical height adjustment, thus adapting to the shelf height within a certain range.

[0028] Two limiting blocks 10 are slidably connected to the inner cavity of the limiting groove 9. The top of the limiting block 10 is fixedly connected to the bottom of the corresponding suction plate 13. One end of the folded hose 20 is fixedly connected to one side of the corresponding suction plate 13. The inner cavity of the folded hose 20 is connected to the inner cavity of the corresponding suction plate 13. During the vacuum adsorption process formed by the working of the vacuum pump 18, the sliding cooperation of the limiting block 10 in the limiting groove 9 plays a guiding and limiting role for the suction plate 13, which enhances the running stability of the suction plate 13. The folded hose 20 expands and contracts during the displacement of the suction plate 13, which ensures the good applicability of the suction plate 13.

[0029] A mounting box 11 is fixedly connected to one side of the movable frame 5. A rotating rod is provided in the inner cavity of the mounting box 11. A drive gear 16 is sleeved on the outer ring of the rotating rod. Two racks 17 are provided in the inner cavity of the mounting box 11. The drive gear 16 can drive the two racks 17 to move relative to each other or towards each other, thereby causing the suction plate 13 to move closer or further away from each other, thus adapting to goods of different sizes within a certain range.

[0030] The mounting box 11 has mounting grooves 21 at the top and bottom of its inner cavity. A mounting slide plate 22 is slidably connected to the inner cavity of the mounting groove 21. One side of the mounting slide plate 22 is fixedly connected to one side of the corresponding rack 17. One side of the rack 17 is fixedly connected to one side of the adjacent suction plate 13. The drive gear 16 and the adjacent rack 17 are meshed through locking teeth. As the rack 17 moves under the drive gear 16, the mounting slide plate 22 slides synchronously in the mounting groove 21 to ensure that the rack 17 runs smoothly and avoids deviation.

[0031] A motor 15 is fixedly installed on one side of the mounting box 11. One end of the rotating rod passes through the inner wall of the adjacent mounting box 11 and is fixedly connected to the output shaft of the motor 15. After the motor 15 is started, it drives the rotating rod to rotate, thereby driving the drive gear 16 to rotate.

[0032] An L-shaped plate 12 is fixedly connected to one side of the mounting box 11. A second electric push rod 23 is fixedly installed on one side of the L-shaped plate 12. A stop plate 24 is fixedly connected to one end of the second electric push rod 23. After the goods are adsorbed and reach the target shelf position, the second electric push rod 23 pushes the stop plate 24 forward to push the goods out of the inside of the moving frame 5 and send them into the shelf.

[0033] Specifically: When goods need to be handled, the electric sliding plate 3 first slides on the ground rail 2, driving the fixed frame 4 to move laterally between the rack rows. The operator controls the first electric push rod 14 through the synchronous controller. The first electric push rod 14 pushes the slider 8 to slide up and down inside its groove 7, thereby driving the moving frame 5 to adjust its height vertically so that the height of the moving frame 5 matches the target rack position. By adjusting the height, the goods to be handled are placed in the inner cavity of the moving frame 5 and positioned between the two suction plates 13. Then, the vacuum pump 18 is started, and the air inside the suction plate 13 is extracted through the double pipe 19 and the folded hose 20, creating a vacuum state in the suction plate 13. The suction holes are used to adsorb and fix the goods on both sides, ensuring that the goods will not slip or fall off during subsequent handling. The motor 15 is started, and the motor 15 drives the rotation... The rotating rod drives the drive gear 16 to rotate, which in turn drives the two meshing racks 17 to move relative to or towards each other. The racks 17 drive the mounting slide plate 22 to slide smoothly inside the mounting groove 21, thereby enabling the two suction plates 13 to move closer or further apart in the horizontal direction. This allows them to adapt to goods of different sizes within a certain range and achieve stable adsorption. During this process, the movement of the suction plates 13 also drives the limiting block 10 to slide synchronously in the limiting groove 9, thereby ensuring the stability and guidance of the suction plates 13 during operation. After the goods are stably adsorbed, the electric sliding plate 3 moves again to move the entire device to the front of the target shelf and completes the positioning. Then, the second electric push rod 23 is activated, which pushes the abutment plate 24 forward, pushing the goods out from between the suction plates 13 and accurately sending them into the shelf, completing the storage of the goods. All components are reset, and the device is ready for the next handling operation.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
