Description

Technical Field

[0001] The utility model relates to the field of AGV robots, in particular to an AGV robot with an automatic material receiving function. Background Art

[0002] AGV robots, as outstanding representatives in the field of modern industrial automation, are gradually becoming the intelligent link connecting all links of the production process with their excellent autonomous navigation and mobility capabilities. These robots cleverly integrate a variety of advanced technologies such as visual recognition, magnetic navigation, and laser positioning. They can accurately track ground markers and achieve unmanned, efficient autonomous movement and precise positioning. In a wide range of scenarios such as factory workshops, storage centers, and logistics hubs, AGV robots, with their unique advantages, undertake key tasks such as product circulation, cargo handling and transportation, greatly improving production efficiency and logistics management levels.

[0003] Especially in the material transmission link between the end of the production line and each workshop, faced with the increased energy consumption and rising costs caused by the long distance of traditional conveyor belts, many forward-looking manufacturing companies have begun to explore and practice more flexible and efficient solutions. Among them, the innovative model that combines manipulators with AGV robots is gradually becoming the mainstream trend in the industry. This model not only effectively shortens the material transfer cycle, but also significantly reduces the dependence on long-distance conveyor belts.

[0004] For example, the Chinese utility model patent with publication number CN221250886U discloses an AGV chassis and an AGV trolley, including an AGV chassis and an AGV trolley, the AGV chassis includes a bottom plate, a bearing mechanism and a driving mechanism, a connecting plate is arranged on one side of the top of the bottom plate; the bearing mechanism includes a connecting frame installed on the connecting plate and a plurality of bearing plates movably installed on the connecting frame; the driving mechanism is installed on the side wall of the connecting plate and the output end is transmission-connected with the connecting frame, wherein the driving mechanism drives the connecting frame to rotate when working, the AGV trolley includes the above AGV chassis and a body, the body is located at the bottom of the AGV chassis, the body includes a frame located at the bottom of the AGV chassis and driving wheels located at the four corners of the bottom of the vehicle.

[0005] However, there are still certain problems in the actual application of the above-mentioned existing technologies. Since the parts are usually placed on the carrying plate, as the AGV starts, stops and turns, the top load may shake due to inertia, which may not only damage the precision parts, but also cause the carrying plate to tilt and the parts to tip over, thereby seriously affecting the safety and stability of transportation. Utility Model Content

[0006] The main technical problem to be solved by the present utility model is to provide an AGV robot with an automatic material receiving function, prevent shaking during the process of carrying objects on the top due to inertia, improve the safety and stability of transportation, and prevent part damage.

[0007] To solve the above technical problems, a technical solution adopted by the present utility model is: to provide an AGV robot with an automatic material receiving function, including: a vehicle body, support plates are symmetrically installed on the top of the vehicle body, a material receiving mechanism is connected between the support plates, and a driving device for driving the material receiving mechanism to rotate is connected to one of the support plates;

[0008] The material receiving mechanism includes a rotating rod and rotating discs connected to both ends thereof, the rotating discs are respectively rotatably connected to the support plates, several rotating arms are respectively connected to the outer circles of the rotating discs, hanging rods are respectively connected to the ends of the rotating arms facing each other and away from the rotating discs, and material receiving components are respectively sleeved on the outer circles of the hanging rods;

[0009] A limiting disc is sleeved on the rotating rod, the limiting disc is arranged away from the driving device, the hanging rods respectively penetrate through the limiting disc and are slidably connected thereto, a telescopic rod assembly is installed on the support plate away from the driving device, when the telescopic rod assembly extends, the side of the driving limiting disc is in contact connection with the material receiving component, and the bottom of the material receiving component is vertically downward, and after the telescopic rod assembly contracts, its extending ends are not in contact with the limiting disc and the rotating arm respectively.

[0010] By adopting the above technical solution, the rotating rod and the rotating disc form the core rotating part of the material receiving mechanism, the whole is driven to rotate by the driving device, the material receiving component is brought to different positions for material receiving operations, realizing automated and efficient operations, improving the material receiving efficiency, reducing manual intervention, being applicable to various automated production lines, and when receiving part transportation, the telescopic rod assembly extends to push the side of the limiting disc into contact connection with the material receiving component, so that the material receiving component maintains a vertically downward posture, preventing shaking due to the inertia generated during transportation, improving the safety and stability of transportation, and preventing part damage.

[0011] In a preferred example of the present utility model, it can be further configured as: the material receiving component includes a material receiving box and movable rings symmetrically sleeved on the rotating rod, connecting rods are symmetrically installed on the movable rings, one ends of the connecting rods are respectively connected to the sides of the material receiving box, and the included angle between adjacent connecting rods is V-shaped, and rubber rings are respectively connected to the opposite sides of the movable rings.

[0012] By adopting the above technical solution, the driving device rotates the material receiving component to the corresponding position, enabling the material receiving box to stably receive parts. Since the included angle between the connecting rods is V-shaped, the material receiving box can adaptively adjust its posture by relying on its own gravity and the weight of the parts already placed during the rotation process, so as to keep the material receiving box always in a vertically downward state, avoiding the crosstalk of parts during the receiving process. When the telescopic rod assembly extends and pushes one side of the limiting disk to contact the material receiving component, the rubber ring will be compressed and undergo a certain deformation, and the material receiving component is firmly fixed in the vertically downward position. This fixed state not only prevents the material receiving box from shaking and tilting due to inertia during transportation, but also ensures the stability and safety of the parts during receiving and transportation.

[0013] In a preferred example of the present utility model, it can be further configured that: magnetic plates one are respectively embedded on the rotating arms close to the rotating disk, and magnetic plates two corresponding to the magnetic plates one are annularly arrayed on one side of the limiting disk close to the magnetic plates one. The magnetic plates two are respectively embedded on the limiting disk, and the corresponding magnetic plates one and the corresponding magnetic plates two are attracted to each other in a special shape.

[0014] By adopting the above technical solution, during the rotation process of the driving device driving the rotating disk, the corresponding magnetic plates one and the corresponding magnetic plates two are respectively attracted to each other and closely fit, preventing the limiting disk from contacting and rubbing against the material receiving component, enabling the material receiving component to perform the material receiving operation in sequence, and improving the material receiving efficiency.

[0015] In a preferred example of the present utility model, it can be further configured that: the telescopic rod assembly includes two symmetrically arranged mounting plates, electric push rods are respectively connected to the mounting plates, the extending ends of the electric push rods are respectively located within the included angle between adjacent two rotating arms, the electric push rods are respectively arranged close to the outer circle of the limiting disk, and the extending ends of the electric push rods are respectively connected with rubber push blocks.

[0016] By adopting the above technical solution, the electric push rods are respectively installed on the mounting plates, and their extending ends are located within the included angle between adjacent two rotating arms, effectively avoiding direct interference with the rotating arms. When the extending ends of the electric push rods extend, through the rubber push blocks, the impact and vibration when the material receiving component contacts the limiting disk are reduced, protecting the relevant components from damage.

[0017] In a preferred example of the present utility model, it can be further configured that: reinforcing ribs are respectively connected to both sides of the bottom of the support plate, and one ends of the reinforcing ribs are respectively connected to the vehicle body.

[0018] By adopting the above technical solution, the reinforcing ribs enhance the overall structural strength of the support plate and its connecting components, provide additional support and rigidity, and prevent deformation or damage when subjected to external forces.

[0019] In a preferred embodiment, the present utility model can be further configured as follows: the driving device is a servo motor.

[0020] By adopting the above technical solution, the servo motor accurately controls the rotation angle and speed of the rotating disk according to the control signal, ensuring that the material receiving component can accurately move to the predetermined position.

[0021] In summary, the present utility model includes at least one of the following beneficial technical effects of an AGV robot with an automatic material receiving function:

[0022] 1. The driving device drives the rotating disk to rotate to the predetermined position, ensuring the precise docking of the material receiving box and the part dropping point, reducing the situation of part dropping or receiving failure caused by position deviation. At the same time, the connecting rod with a V-shaped angle design enables the material receiving box to adaptively adjust its posture when receiving parts and maintain a vertically downward state, effectively preventing the crosstalk and inclination of the parts during the receiving process and ensuring the stable receiving of the parts.

[0023] 2. By extending the telescopic rod assembly, the limiting disk is pushed into close contact with the material receiving component, and the material receiving box is fixed in a vertically downward state by compressing the rubber ring, preventing the shaking and inclination of the material receiving box caused by inertia during transportation, and also ensuring the stability and safety of the parts during receiving and transportation.

[0033] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not intended to limit the present invention.

[0034] It should be noted that these drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention.

[0035] Refer to Figures 1-5, an AGV robot with an automatic material receiving function disclosed by the present utility model, includes: a vehicle body 1, support plates 2 are symmetrically installed on the top of the vehicle body 1, reinforcing ribs 5 are respectively connected to both sides of the bottom of the support plates 2, one end of each reinforcing rib 5 is connected to the vehicle body 1, a material receiving mechanism 30 is connected between the support plates 2, and a driving device 4 for driving the material receiving mechanism 30 to rotate is connected to one of the support plates 2. The driving device 4 is a servo motor. The material receiving mechanism 30 includes a rotating rod 31 and rotating discs 32 connected to both ends thereof. The rotating discs 32 are respectively rotatably connected to the support plates 2. A plurality of rotating arms 33 are respectively connected to the outer circumference of the rotating discs 32. Hanging rods 34 are respectively connected to the side of the rotating arms 33 facing each other and away from the rotating discs 32. Material receiving components 35 are respectively sleeved on the outer circumference of the hanging rods 34. A limiting disc 37 is sleeved on the rotating rod 31. The limiting disc 37 is arranged away from the driving device 4. The hanging rods 34 respectively penetrate through the limiting disc 37 and are slidably connected thereto. A telescopic rod assembly 38 is installed on the support plate 2 away from the driving device 4. When the telescopic rod assembly 38 extends, the side of the driving limiting disc 37 is in contact connection with the material receiving component 35, and the bottom of the material receiving component 35 is vertically downward. After the telescopic rod assembly 38 contracts, its extending ends are not in contact with the limiting disc 37 and the rotating arms 33 respectively; preferably, there are 4-6 rotating arms 33 on each rotating disc 32 to increase the number of materials received. Using a servo motor as the drive, the material receiving component 35 is brought to different positions for material receiving operations, improving the material receiving efficiency and accuracy. When receiving part transportation, the telescopic rod assembly 38 extends to push the side of the limiting disc 37 into contact connection with the material receiving component 35, so that the material receiving component 35 maintains a vertically downward posture, preventing shaking due to inertial forces during transportation, improving the safety and stability of transportation, and preventing part damage.

[0036] The material receiving component 35 includes a material receiving box 351 and movable rings 352 symmetrically sleeved on the rotating rod 31. Connecting rods 353 are symmetrically installed on the movable rings 352. One end of each connecting rod 353 is respectively connected to the side of the material receiving box 351, and the included angle between adjacent connecting rods 353 is V-shaped. Rubber rings 354 are respectively connected to the opposite sides of the movable rings 352; the included angle between adjacent connecting rods 353 being V-shaped is 30 degrees - 80 degrees, enabling the material receiving box 351 to adaptively adjust its posture depending on its own gravity and the weight of the parts already placed during the rotation process, so as to keep the material receiving box 351 always in a vertically downward state, avoiding the crosstalk of parts during the receiving process. The rubber rings 354 are compressed and deformed when the telescopic rod assembly 38 extends, stably fixing the material receiving box 351 in a vertically downward state and preventing the shaking and tilting of the material receiving box 351 due to inertial forces during transportation.

[0037] Magnetic plates 39 are respectively embedded on the rotary arms 33 close to the rotary disk 32. On one side of the limit disk 37 close to the magnetic plates 39, magnetic plates 36 corresponding to the magnetic plates 39 are arranged in an annular array. The magnetic plates 36 are respectively embedded on the limit disk 37. The corresponding magnetic plates 39 and the corresponding magnetic plates 36 attract each other in a special shape. During the rotation of the driving device 4 to drive the rotary disk 32, the corresponding magnetic plates 39 and the corresponding magnetic plates 36 attract and fit closely with each other, ensuring the stable rotation of the rotary disk 32, preventing the limit disk 37 from contacting and rubbing against the material receiving assembly 35, enabling the material receiving assembly 35 to perform the material receiving operation in sequence, and improving the material receiving efficiency.

[0038] The telescopic rod assembly 38 includes two symmetrically arranged mounting plates 381. Electric push rods 382 are respectively connected to the mounting plates 381. The extending ends of the electric push rods 382 are respectively located within the included angle between adjacent rotary arms 33. The electric push rods 382 are respectively arranged close to the outer circle of the limit disk 37. Rubber push blocks 383 are respectively connected to the extending ends of the electric push rods 382. The extending ends of the electric push rods 382 are located within the included angle between adjacent rotary arms 33, effectively avoiding direct interference with the rotary arms 33. When the extending ends of the electric push rods 382 extend, the rubber push blocks 383 reduce the impact and vibration when the material receiving assembly 35 contacts the limit disk 37, protecting the relevant components from damage.

[0039] The implementation principle of this embodiment is as follows: During use, the manipulator on the production line places the parts on the production line into the material receiving box 351 in sequence. At the same time, the driving device 4 drives the rotary disk 32 to rotate, so that the rotary arms 33 drive the corresponding material receiving boxes 351 to rotate to different positions for material receiving operations. During the process of the material receiving box 351 rotating for material receiving, it adaptively adjusts its posture relying on its own gravity and the weight of the parts already placed, and always maintains a vertically downward state. At the same time, after the parts receiving is completed, the electric push rods 382 extend, driving the separation of the magnetic plates 39 and the magnetic plates 36, and pushing one side of the limit disk 37 to contact the movable ring 352, and the other movable ring 352 contacts the rotary arm 33, while squeezing the rubber ring 354, fixing the material receiving box 351 in a vertically downward state, preventing the material receiving box 351 from shaking and tilting due to inertia during transportation.

[0040] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present invention.
