Description

Technical Field

[0001] This invention relates to the field of AGV robot technology, and in particular to a fixed-axis lifting load-bearing structure based on an AGV intelligent robot. Background Technology

[0002] AGV (Automated Guided Vehicle) robots are a type of automated guided vehicle, also known as an unmanned automated vehicle equipped with electromagnetic or optical automatic guidance devices. The main characteristics of AGVs include battery power, non-contact guidance, and the ability to move and stop precisely at designated locations under computer monitoring, following path planning and operational requirements to complete a series of tasks. These robots, characterized by wheeled movement, offer advantages over walking, crawling, or other non-wheeled mobile robots, including faster movement, higher efficiency, simpler structure, stronger controllability, and better safety. However, existing AGV intelligent robots with fixed-axis lifting bearing structures generally only function to raise and lower the bearing plate, failing to clamp and secure the carried goods. This can lead to goods falling off during transport. Furthermore, the clamping devices on some bearing plates are often manually fixed and unfixed, which is time-consuming, labor-intensive, and lacks automation. When handling taller goods, this can also cause the goods to tilt and fall during transport, as there is no protective measure for taller goods. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as: the fixed-axis lifting bearing structure of existing AGV intelligent robots generally only moves the bearing plate up and down, and cannot clamp and fix the carried goods. When the robot transports goods, the goods may fall off. At the same time, the clamping devices of some bearing plates are generally fixed and unfixed manually, which is time-consuming, labor-intensive and not intelligent enough. When handling some tall goods, the goods may also tilt during transportation and fall off. There is no way to protect tall goods.

[0010] Preferably, the protective assembly has a symmetrical structure, comprising a protective plate. A rotating shaft is rotatably connected to each of the two side walls of the mounting plate. Two protective plates are respectively fixedly connected to the two rotating shafts. Two rotating shafts are rotatably connected to the mounting plate, and gears are fixedly connected to each of the two rotating shafts, with the two gears meshing with each other. A belt connects the rotating shafts and the rotating shafts, and the rotating shafts are connected via belt drive. A slide rail is provided on the protective plate, and a pad is slidably connected within the slide rail. Gears are rotatably connected within the protective plate. Wheel 2, the protective plate also has a rack 1 and a rack 2 slidably connected inside, and rack 1 and rack 2 are respectively located at both ends of gear 2. Both rack 1 and rack 2 are matched and meshed with gear 2. One end of rack 1 slides through the protective plate.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] See Figures 1-6 A fixed-axis lifting bearing structure based on AGV intelligent robot includes a base 1, an mounting plate 2 mounted on the base 1, a lifting assembly 3 for lifting the mounting plate 2 mounted on the base 1, and a clamping assembly 4 for clamping and fixing goods mounted on the mounting plate 2.

[0030] The lifting assembly includes a motor 31, a groove 32 on the base 1, the motor 31 being installed inside the groove 32, and a screw 34 being fixedly connected to the output shaft of the motor 31. A threaded cylinder 35 is installed on the screw 34 and matches the screw 34. The threaded cylinder 35 is fixedly connected to the bottom of the mounting plate 2. When it is necessary to adjust the mounting plate 2 up and down, the motor 31 is started, and the output shaft of the motor 31 drives the screw 34 to rotate. The threaded cylinder 35 moves up and down through its cooperation with the screw 34, thereby causing the threaded cylinder 35 to drive the mounting plate 2 to move up and down, thus realizing the function of adjusting the position of the mounting plate 2.

[0031] Clamping assembly 4 includes clamping plates 41. The clamping assembly 4 has a symmetrical structure, with two clamping plates 41 slidably mounted on mounting plate 2. Mounting plate 2 has mounting grooves 9, and a sliding plate 42 is slidably connected to the mounting grooves 9. The sliding plate 42 is fixedly connected to the clamping plates 41. A spring 43 connects the sliding plate 42 to the inner wall of the mounting groove 9. A pressure plate 44 is slidably mounted on mounting plate 2, and a connecting rod 45 is fixedly connected to the bottom of the pressure plate 44. A second sliding plate 46 is slidably connected to the mounting groove 9, and is fixedly connected to the connecting rod 45. A spring 47 connects the sliding plate 46 to the mounting groove 9. Limiting blocks 48 are fixedly connected to both ends of the sliding plate 46. Each of the two sliding plates 42 has slots 49, the positions of which match the limiting blocks 48. The initial position of mounting plate 2 is not at the bottom, and at this time it is not disengaged from the inclined plate 53 of the restoration assembly 5. When goods are placed on the pressure plate 44, the goods compress and cause the pressure plate 44 to slide downward. The pressure plate 44 drives the slide plate 46 to slide downward through the connecting rod 45. The slide plate 46 drives the limiting blocks 48 on both sides to move downward. The initial position of the limiting blocks 48 is above the slot 49. The spring 46 is initially in a compressed state. At the same time, the limiting blocks 48 initially abut against the slide plate 42 and restrict its sliding. Therefore, after the limiting blocks 48 slide downward, the limiting blocks 48 enter the slot 49 and cancel the abutment and restriction on the slide plate 42. The two slide plates 42 slide towards the center under the elastic force of the two springs 43, and at the same time drive the two clamping plates 41 to slide towards the center. While correcting the position of the goods, the goods are fixed, thereby avoiding uneven force on the mounting plate due to uneven placement of the goods, which would cause the mounting plate 2 to tilt.

[0032] Mounting plate 2 is equipped with a restoration component 5 for restoring clamping component 4, and a protective component 6 for protecting taller goods.

[0033] The restoration component 5 includes a contact rod 51. The restoration component 5 has a symmetrical structure. Two sliding grooves 52 are opened at the bottom of the mounting plate 2, and both sliding grooves 52 communicate with the mounting groove 9. The contact rod 51 is fixedly connected to the bottom of the slide plate 42, and the two contact rods 51 are slidably connected to the two sliding grooves 52 respectively. Two inclined plates 53 are fixedly connected to the base 1, and the positions of the two inclined plates 53 match the two contact rods 51. When the device transports goods to the designated position, the drive motor 31 causes the lifting component 3 to lower the mounting plate 2 to its lowest point. During this process, the two slide rods 51 are disengaged from the two inclined plates 53, and under the action of the inclined plates 53, the two slide rods 51 slide to the sides respectively, while simultaneously driving the two slide plates 42 to slide to the sides. The two slide plates 42 drive the two clamping plates 41 to slide to the sides to return to their original positions. At this time, the goods are removed, and the second slide plate 46 slides upward under the elastic force of the second spring 47, while simultaneously driving the limiting blocks 48 on both sides to slide upward, re-limiting the two slide plates 42, thereby realizing the restoration of the clamping assembly 4, which is convenient for subsequent use of the device.

[0034] The protective assembly 6 has a symmetrical structure and includes a protective plate 61. Two rotating shafts 62 are rotatably connected to both sides of the mounting plate 2. The two protective plates 61 are fixedly connected to the two rotating shafts 62. Two rotating shafts 64 are rotatably connected to the mounting plate 2, and gears 65 are fixedly connected to each of the two rotating shafts 64, with the two gears 65 meshing with each other. A belt 63 connects the rotating shafts 62 and 64, and the rotating shafts 62 and 64 are driven by the belt 63. A slide rail 10 is provided on the protective plate 61, and a pad 69 is slidably connected within the slide rail 10. A gear 66 is rotatably connected within the protective plate 61. A rack 67 and a rack 68 are also slidably connected within the protective plate 61, with racks 67 and 68 located at the two ends of gear 66, respectively. Both rack 67 and rack 68 mesh with gear 66. One end of rack 67 slides through protective plate 61. Two baffles 12 are installed on mounting plate 2, and the positions of the two baffles 12 match the two racks 67 respectively. A detection element 11 for detecting the height of goods is installed on mounting plate 2. A motor is installed on mounting plate 2, and one of the rotating shafts 64 is fixedly connected to the output shaft of motor 2. The detection element 11 is connected to the power supply of motor 2. When the detection element 11 detects that the goods are too high, it triggers motor 2 to run. The output shaft of motor 2 drives rotating shaft 64 to rotate, and rotating shaft 64 drives gear 65 to rotate. With the cooperation of the two gears 65, the two rotating shafts 64 rotate simultaneously. The two rotating shafts 64 drive the two rotating shafts 62 to rotate through belt 63 respectively. Figure 5As shown, the two rotating shafts 62 drive the two protective plates 61 to rotate to the designated position to achieve the protection of tall goods. During this movement, the rack 67 abuts against the baffle 12 and slides under the force of the baffle 12. The sliding of the rack 67 drives the gear 66 to rotate. The gear 66 drives the rack 68 to slide outward. The rack 68 drives the pad 69 to slide outward, so that when the protective component 6 is triggered, the pad 69 pops out to further protect the goods.

[0035] A fixing block 33 is fixedly connected inside the groove 32 for additional fixing of the motor 31. The fixing block 33 can further fix the motor 31 and improve the stability of the device operation.

[0036] Multiple sets of brackets 13 are installed on both sides of the mounting plate 2. The multiple sets of brackets 13 are rotatably connected to the two rotating shafts 62 respectively. The multiple sets of brackets 13 can further support and fix the two rotating shafts 62, thereby improving the stability of the equipment.

[0037] A spring rod is connected between the two pads 69 and the inner wall of the slide rail 10, and the two ends of the spring rod are fixedly connected to the pads 69 and the slide rail 10 respectively. The spring rod can make the pads 69 return to their original position when the protective component 6 returns to its original position, thus improving the practicality of the device.

[0038] Multiple sets of telescopic rods 8 are installed on the base 1. The ends of the telescopic rods 8 are fixedly connected to the mounting plate 2. By installing multiple sets of telescopic rods 8, the mounting plate 2 can be more stable and efficient when lifting high goods.

[0039] The base 1 has multiple sets of casters 7 installed at its bottom. Casters 7 are existing technology, so they will not be described in detail.

[0040] In this invention, when the mounting plate 2 needs to be adjusted up and down, motor 31 is started. The output shaft of motor 31 drives screw 34 to rotate. Threaded cylinder 35 moves up and down in cooperation with screw 34, thereby causing mounting plate 2 to move up and down, thus adjusting the position of mounting plate 2. When goods are placed on pressure plate 44, the goods compress and cause pressure plate 44 to slide downwards. Pressure plate 44 drives sliding plate 46 downwards via connecting rod 45. Sliding plate 46 causes the limiting blocks 48 on both sides to move downwards. After the limiting blocks 48 slide downwards, they enter the slot 49 and cancel their resistance to sliding plate 42. The two sliding plates 42 slide towards the center under the elastic force of two springs 43, simultaneously causing the two clamping plates 41 to slide towards the center. This corrects the position of the goods and fixes them, thus preventing uneven force on the mounting plate due to uneven placement of goods, which could cause mounting plate 2 to tilt. When the device transports goods... Upon reaching the designated position, drive motor 31 lowers the lifting assembly 3 and mounting plate 2 to its lowest point. During this process, the two sliding rods 51 disengage from the two inclined plates 53, and under the action of the inclined plates 53, the two sliding rods 51 slide to both sides, simultaneously driving the two sliding plates 42 to slide to both sides. The two sliding plates 42 then drive the two clamping plates 41 to slide to both sides to return to their original positions. At this time, the goods are removed, and the second sliding plate 46 slides upward under the elastic force of the second spring 47, simultaneously driving the limit blocks 48 on both sides to slide upward, re-limiting the two sliding plates 42, thereby restoring the clamping assembly 4 and facilitating subsequent use of the device. When the detection element 11 detects that the goods are too high, it triggers motor 2 to operate. The output shaft of motor 2 drives the rotating shaft 64 to rotate, and the rotating shaft 64 drives the gear 65 to rotate. Through the cooperation of the two gears 65, the two rotating shafts 64 rotate simultaneously. The two rotating shafts 64 drive the two rotating shafts 62 to rotate through belts 63, as follows. Figure 5 As shown, the two rotating shafts 62 drive the two protective plates 61 to rotate to the designated position to achieve the protection of tall goods. During this movement, the rack 67 abuts against the baffle 12 and slides under the force of the baffle 12. The sliding of the rack 67 drives the gear 66 to rotate. The gear 66 drives the rack 68 to slide outward. The rack 68 drives the pad 69 to slide outward, so that when the protective component 6 is triggered, the pad 69 pops out to further protect the goods.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
