Description

Technical Field

[0001] This utility model relates to the field of AGV technology, specifically to an automatic guidance device for industrial robot AGVs. Background Technology

[0002] In today's industrial production sector, the wave of automation and intelligence is advancing at an unprecedented speed. Enterprises are increasingly eager to improve production efficiency, reduce labor costs, and enhance product quality. As a key piece of equipment for realizing automated industrial logistics and transportation, industrial AGVs have emerged and are widely used. The emergence of AGVs has brought revolutionary changes to industrial logistics and transportation. They can automatically travel along preset paths and accurately transport materials from one location to another without human intervention, greatly improving the efficiency and accuracy of material handling.

[0003] In industrial automated production, AGVs (Automated Guided Vehicles) play a crucial role as important material handling and navigation equipment. LiDAR, as one of the core sensors of the AGV, is responsible for real-time perception of the surrounding environment, providing accurate navigation and obstacle avoidance information. Its normal operation directly affects the AGV's operational efficiency and safety. In dusty environments, a large amount of dust easily adheres to the surface of the LiDAR, blocking its emitted and received light, leading to decreased radar detection accuracy or even malfunction. This, in turn, affects the navigation accuracy of the AGV, potentially causing it to deviate from its intended route or collide with obstacles during operation. In humid environments, moisture in the air may penetrate the LiDAR, corroding its delicate electronic components, damaging the circuit structure, causing radar malfunctions, and shortening the equipment's lifespan. Therefore, those skilled in the art provide an automatic guidance device for industrial AGVs to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide an automatic guidance device for industrial robots (AGVs) to solve the problems mentioned in the background art.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model incorporates a protective mechanism. During use, lidar inevitably encounters complex environments, such as dusty or humid conditions. To protect the lidar, a protective mechanism is employed.

Simultaneously, as the fixed plate moves, it pulls the corrugated protective tube, causing it to extend and retract. Driven by the protective mechanism, the through hole is sealed, and the corrugated protective tube forms an outer wall around the lidar, effectively enclosing it. This design effectively protects the lidar from damage when the AGV encounters complex environments. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4As shown, this utility model provides a technical solution: an automatic guidance device for an industrial robot AGV, including an AGV trolley body 1, a placement groove 10 is provided in the middle of the outer side wall of the AGV trolley body 1, an extension column 11 is fixedly connected to the middle of the inner side wall of the placement groove 10, a laser radar 3 for sensing the external environment is fixedly connected to the side of the extension column 11 away from the placement groove 10, and a protective mechanism 4 for protecting the laser radar 3 is provided inside the placement groove 10.

[0022] It should be noted that the extension column 11 provides a suitable installation position for the lidar 3, enabling it to better sense the external environment, expand the sensing range, and improve the perception accuracy of the surrounding environment. This ensures that the AGV trolley body 1 can accurately acquire surrounding information during operation, make timely and correct navigation decisions, and guarantee the safety and stability of operation. The protective mechanism 4 set inside the placement slot 10 provides reliable protection for the lidar 3. In the industrial environment, there are various factors that may damage the lidar 3, such as collisions, dust, and liquids. The protective mechanism 4 can effectively resist these adverse factors and reduce the risk of damage to the lidar 3.

[0023] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the protective mechanism 4 includes two electric push rods 41 symmetrically fixedly connected to the inner wall of the placement groove 10. The telescopic ends of the two electric push rods 41 are fixedly connected to a connecting plate 42. A corrugated protective tube 49 is fixedly connected to the side of the connecting plate 42 near the electric push rods 41. The corrugated protective tube 49 is sleeved on the outer wall of the two electric push rods 41, and the other end of the corrugated protective tube 49 away from the electric push rods 41 is fixedly connected to the inner wall of the placement groove 10. Two side plates 43 are symmetrically fixedly connected to the side of the connecting plate 42 away from the electric push rods 41. A limit slot 431 is opened on the opposite side of the two side plates 43. Two protective plates 45 are symmetrically arranged inside the two side plates 43. A slider 451 is fixedly connected to the outer wall of each of the two protective plates 45. Each protective plate 45 is slidably sleeved with the limit slot 431 through the slider 451.

[0024] It should be noted that the electric push rod 41 can flexibly control the movement of the connecting plate 42. When the AGV trolley body 1 is not in operation or faces potential danger, it can push the connecting plate 42 closer to the lidar 3 to provide protection. When in operation, it can be retracted without affecting the normal sensing of the lidar 3. The corrugated protective tube 49 is sleeved on the outer wall of the electric push rod 41 and moves and extends with the connecting plate 42. It can not only effectively prevent dust, liquid and other impurities from entering the placement tank 10 and corroding the electric push rod 41, thus extending its service life, but also prevent accidental collisions from damaging the electric push rod 41 and ensure its stable operation.

[0025] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, each protective plate 45 has a limiting block 452 fixedly connected to the side away from the electric push rod 41. A first gear 44 is rotatably sleeved on the side of the two side plates 43 away from the connecting plate 42. Two symmetrical rotating grooves 441 are opened on the side of the first gear 44 near the side plate 43. The protective plate 45 is slidably sleeved inside the rotating grooves 441 through the limiting block 452. A through hole 421 is opened at the center of both the first gear 44 and the connecting plate 42. A protective cover 47 is fixedly connected to the outer wall of the connecting plate 42. The outer side of the protective cover 47... An opening 471 is provided through the wall to facilitate the removal of the protective plate 45. The protective cover 47 is sleeved on the outer wall of the first gear 44. A drive motor 48 is fixedly connected to the side of the protective cover 47 near the connecting plate 42. A drive rod 481 is fixedly connected to the output end of the drive motor 48. A second gear 46 that meshes with the first gear 44 is rotatably sleeved on the inner wall of the protective cover 47. The end of the drive rod 481 away from the drive motor 48 is fixedly connected to the center of the second gear 46. The drive rod 481 is rotatably sleeved with the contact surface of the protective cover 47 through a bearing.

[0026] It should be noted that the limiting block 452 of the protective plate 45 is slidably sleeved with the rotation groove 441 of the first gear 44. This, combined with the drive motor 48 driving the second gear 46 to rotate, and in turn driving the first gear 44 to rotate, allows for flexible control of the movement of the protective plate 45. When enhanced protection is needed, the protective plate 45 can be quickly deployed to provide more robust protection for the lidar 3. During normal operation, the protective plate 45 can be retracted to avoid affecting the sensing range of the lidar 3. The protective cover 47 provides additional protection for components such as the electric push rod 41, preventing dust and debris from entering, reducing the risk of equipment failure, and extending service life. The opening 471 on its outer wall facilitates the removal of the protective plate 45, ensuring the normal operation of the protective function. The precise control of the deployment and retraction of the protective plate 45 by the drive motor 48 achieves automation and intelligence in protection. The protective state can be flexibly adjusted according to different working conditions and levels of danger, improving the targeting and effectiveness of the protection.

[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, control panels 2 are fixedly connected to both sides of the lidar 3 on the outer side wall of the AGV body 1. Fixing rods 5 are fixedly connected to the four corners of the top of the AGV body 1. The four fixing rods 5, away from the AGV body 1, are fixedly connected to a placement frame 6.

[0028] It should be noted that the control panel 2 is set on both sides of the lidar 3, which greatly facilitates the operator's control and debugging of the AGV. The operator does not need to go to a specific location, but can easily operate it from both sides of the lidar 3, which improves work efficiency. Especially when it is necessary to frequently adjust parameters or deal with emergencies, it can respond quickly, reduce operation time, and ensure the smooth production process. The four corners of the top of the AGV body 1 are fixedly connected to the fixing rods 5, and the four fixing rods 5 are connected to the placement frame 6, which expands the additional load-bearing space of the AGV body 1. The placement frame 6 can be used to place some production-related tools, small parts or auxiliary equipment, so that the AGV body can carry other necessary items while transporting goods, which improves its functional versatility and practicality.

[0029] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, two fixed plates 7 are symmetrically fixedly connected to the outer side wall of the AGV trolley body 1. Hydraulic push rods 8 are fixedly connected to the bottom ends of the two fixed plates 7, and counterweight plates 9 are fixedly connected to the telescopic ends of the two hydraulic push rods 8.

[0030] It should be noted that when the AGV trolley 1 is carrying heavy goods or running on complex terrain (such as slopes or uneven ground), the hydraulic push rod 8 can flexibly control the counterweight plate 9 to descend, increasing the contact pressure between the trolley and the ground, thereby effectively lowering the center of gravity of the trolley, enhancing its stability, preventing it from tipping over due to an excessively high center of gravity or uneven ground, and ensuring the safety of the goods and the trolley itself.

[0031] Working principle: During the operation of the AGV main body 1, the lidar 3 is used to sense the external environment, but it is easily damaged in complex environments such as dust and humidity. At this time, the protective mechanism 4 plays a role. When protection needs to be activated, the telescopic ends of the two electric push rods 41 extend, driving the connecting plate 42 to move linearly. The connecting plate 42 gradually moves out of the placement slot 10. During the movement of the connecting plate 42, the corrugated protective tube 49 is pulled to telescopically. The corrugated protective tube 49 is always sleeved on the outer wall of the electric push rod 41, and one end is fixed to the inner side wall of the placement slot 10, which can effectively prevent dust, liquid and other impurities from entering the placement slot 10 and corroding the electric push rod 41.

[0032] Simultaneously, the drive motor 48 starts, and the drive rod 481 drives the second gear 46 to rotate. Since the second gear 46 meshes with the first gear 44, the first gear 44 rotates accordingly. The rotation groove 441 on the first gear 44 pulls the limiting block 452 of the protective plate 45, so that the protective plate 45 slides in the limiting groove 431 of the side plate 43 through the slider 451. The two protective plates 45 gradually approach each other, thereby closing the through hole 421. The corrugated protective tube 49 is located on the outer wall of the laser radar 3, which plays a role in wrapping and protecting it. In addition, the control panel 2 is convenient for operators to control and debug. The placement frame 6 is fixed to the top four corners of the AGV trolley body 1 by the fixing rod 5, and can carry tools and other items. The telescopic end of the hydraulic push rod 8 can drive the counterweight plate 9 to rise and fall, which lowers the center of gravity and enhances stability in complex terrain or under heavy load, and rises to reduce resistance when moving quickly.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
