Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to an AGV (Automated Guided Vehicle) early warning device. Background Technology

[0002] AGV (Automated Guided Vehicle) transporters, as core equipment in modern logistics warehousing, achieve efficient material transfer through automatic navigation technology. With increasingly complex application scenarios, the safety requirements for transported goods are rising, especially in the transport of fragile and high-value goods, where real-time prevention of risks such as falling, tilting, and collisions is necessary.

[0003] Currently, most AGV (Automated Guided Vehicle) transporters use fixed-height single-layer photoelectric sensors or mechanical anti-collision strips, which can only monitor a single plane and cannot cover the entire height range of the goods. When the height of the goods changes or when there is a mid-level shift or top collision, the system cannot provide timely warnings, resulting in blind spots. Furthermore, traditional protective structures are mostly fixed or manually adjustable, making it difficult to dynamically adapt to goods of different sizes. For oversized or overheight goods, either the monitoring fails due to insufficient protection range, or excessive expansion occupies aisle space, increasing the risk of false triggering.

[0004] Therefore, an early warning device for AGV transport vehicles is proposed. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an AGV transport vehicle early warning device.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an AGV transport vehicle early warning device, including an AGV body, with early warning components for arranging detection gratings around the cargo at the four corners of the AGV body. The early warning components include a connecting shaft, with a sleeve connected to the connecting shaft on the side away from the AGV body. The upper end of the sleeve is open and connected to a bracket. The top of the bracket has a bottom measurement module, a middle measurement module, and a top measurement module. Each of the bottom measurement module, middle measurement module, and top measurement module consists of a fixed frame, a laser emitter, and a laser receiver. The laser emitter and laser receiver are respectively installed at the left and right ends of the fixed frame.

[0007] As a preferred embodiment of the present invention, the early warning component is provided with an adjustment component for adjusting the spacing to change the height. The adjustment component includes a screw, a bottom measuring module, and a middle measuring module with slots on their top surfaces that are rotatably connected to the screw. The bottom ends of both the middle and top measuring modules are connected to threaded cylinders, which are threadedly connected to the corresponding screws. A driven gear ring is connected to the outer wall of the bottom end of the screw. The top surfaces of the bottom and middle measuring modules have holes on one side of the driven gear ring, and a transmission cylinder is rotatably connected within the holes. A driving gear ring is connected to the outer wall of the bottom end of the transmission cylinder, and the driving gear ring meshes with the corresponding driven gear ring. A transmission cylinder is inserted into the transmission cylinder. The top of the key is connected to the bottom of the corresponding transmission cylinder. The top surface of the top module has a hole that is rotatably connected to the topmost key. The top surfaces of the bottom and middle modules are connected to guide cylinders on the opposite side of the transmission cylinder. The bottom surfaces of the middle and top modules are connected to guide rods on the opposite side of the transmission cylinder. The top surface of the guide cylinder has a hole that fits the guide rod, and the guide rod is fitted inside the guide cylinder. The side of the bracket away from the AGV body is connected to a motor frame. A lifting motor is installed on the motor frame. The drive shaft of the lifting motor is connected to a pulley. The bottom of the bottommost transmission cylinder is also connected to a pulley. The two pulleys are connected by a transmission belt.

[0008] As a preferred embodiment of the present invention, the AGV body is provided with an expansion component for adjusting the distance between the warning component and the AGV body. A support frame is connected to the top surface of the AGV body. The support frame has a certain thickness and is adapted to the shape of the AGV body platform. A placement platform is connected to the top surface of the support frame. The expansion component includes four guide rails, which are respectively connected to the top surface of the AGV body. The guide rails are located inside the support frame and are perpendicular to the warning component on the corresponding side. A slide block is slidably connected to the guide rail, and a T-shaped fixing element is connected to the top surface of the slide block. The AGV has two fixed shafts in opposite positions, each fitted with a sleeve plate. Two oblong holes are formed on the top surface of the sleeve plate. A push rod is mounted on the slide, with its free end passing through the support frame and mounted on the connecting shaft. Double-ended screws are threaded onto the two fixed shafts, which are respectively threaded to the two ends of the double-ended screws. A drive motor is mounted on one side of the AGV body, and its transmission shaft is connected to the double-ended screws. A plug rod is connected to one end of the slide corresponding to the push rod. The plug rod has a helical groove, and the end of the push rod corresponding to the plug rod has a hole that fits the plug rod, with the plug rod fitting into the hole. The inner wall of the push rod is connected to a shaft, which is adapted to the groove size of the spiral groove and located within the groove. One end of the push rod outside the AGV body is connected to a telescopic plate via a bearing. A limit rod is connected to the side of the telescopic plate corresponding to the AGV body. The AGV body has a hole for the limit rod to pass through. One side of the telescopic plate has a groove, and the end of the push rod located within the groove is connected to a gear. A hole is opened on the top surface of the telescopic plate, into which a gear frame is inserted. One side of the gear frame has teeth that mesh with the gear frame. A connecting plate is connected to the bottom surface of the gear frame, and the connecting plate is connected to a connecting shaft. The outer wall is fitted with a contact spring. The push rod has an annular protrusion at one end inside the AGV body, which abuts against the contact spring. A hole is opened on one side of the top of the tooth frame, and a photoelectric sensor is installed in the hole. The photoelectric sensor is used to detect the top position of the goods. The top of the tooth frame has a slanted protrusion. Both the top of the tooth frame and the slanted protrusion have through holes. A convex roller is rotatably connected in the through hole. The outer wall of the convex roller protrudes from the inner wall of the tooth frame. Warning rods are connected to both sides of the sleeve. The warning rods are bent and adapted to the outer wall of the AGV body. Warning components are provided on the surface of the warning rods.

[0009] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. Through the coordinated lifting of three sets of laser detection modules, a three-dimensional grating network is formed to cover the entire height of the packaged goods. The bottom grating monitors the displacement of the goods and the support in real time to prevent accidental falls, the middle grating detects the tilting and shifting of the goods and warns of instability of the center of gravity, and the top grating intercepts the risk of collision with high-altitude obstacles, achieving all-round protection from fall prevention, tilt prevention to collision prevention, and adapting to goods of different heights.

[0010] 2. When the expansion component expands the position of the warning component, if the warning component encounters resistance while rising, the spiral groove of the insert rod drives the push rod to rotate, automatically switching to the horizontal expansion mode. This allows the laser grating to accurately match the width of the goods, and automatically switches back to the rising state when it reaches the edge of the goods. This automatically expands the warning component to the appropriate position, ensuring the stability of the laser grating's protective function while avoiding excessive expansion that would occupy space or increase the risk of collision. During loading and unloading, the expansion component drives the warning component to descend and retract, reducing space occupation and avoiding obstruction of goods handling.

[0011] 3. Only the drive motor is needed to control the horizontal expansion and lifting switching, and the lifting motor to adjust the height of the detection module. The dual motors work together to complete all key actions, greatly simplifying the system complexity and improving response efficiency and reliability.

[0012] 4. The expansion component is linked to the bending warning bar and moves outward. The reflective strip or light strip outlines the actual shape of the goods in real time, actively reminding people in the surrounding area to maintain a safe distance. It provides physical warning while also providing active protection based on vision. Attached Figure Description

Detailed Implementation

[0015] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0016] Example: Figure 1 and Figure 3As shown, an AGV (Automated Guided Vehicle) transporter warning device includes an AGV body 10. Warning components 11 for arranging detection gratings around the cargo are provided at each of the four corners of the AGV body 10. Each warning component 11 includes a connecting shaft 12. A sleeve 13 is connected to the side of the connecting shaft 12 facing away from the AGV body 10. The upper end of the sleeve 13 is open and connected to a bracket 14. A bottom-measuring module 15, a middle-measuring module 16, and a top-measuring module 17 are distributed from bottom to top on the top of the bracket 14. Each of the bottom-measuring module 15, middle-measuring module 16, and top-measuring module 17 consists of a fixing frame 18, a laser emitter 19, and a laser receiver 20. Laser emitter 19 and laser receiver 20 are respectively installed at the left and right ends of the fixed frame 18. Both ends of the fixed frame 18 are bent, so that laser emitter 19 and laser receiver 20 are set along the side wall of the AGV body 10. It should be noted that the laser emitter 19 and laser receiver 20 in the two warning components 11 on the opposite side are distributed in a corresponding manner. Laser emitter 19 emits laser light for laser receiver 20 to receive. Several bottom measuring modules 15, middle measuring modules 16 and top measuring modules 17 form a grating. When the laser light is blocked due to falling goods or personnel involvement, the laser light cannot be received and a signal is emitted to issue a warning.

[0017] Specifically, a laser emitter 19 emits a laser beam, and a laser receiver 20 receives the laser beam emitted by the laser emitter 19, forming a laser grating on the four sides of the AGV body 10. When the goods tilt, fall, or an obstacle passes through the laser grating and is about to touch the goods, the laser receiver 20 at the corresponding position will send a signal because it cannot receive the laser beam, triggering the feedback action of the AGV body 10 and the operation of the alarm device. This achieves timely warning when there is a risk of damage to the goods, thereby providing more comprehensive protection for the goods.

[0018] like Figure 3 and Figure 4As shown, an adjustment assembly for adjusting the spacing to change the height is provided between the bottom measurement module 15, the middle measurement module 16, and the top measurement module 17. The adjustment assembly includes a screw 21. The top surfaces of the bottom measurement module 15 and the middle measurement module 16 are slotted and rotatably connected to the screw 21 via bearings. The bottom ends of the middle measurement module 16 and the top measurement module 17 are each connected to a threaded cylinder 22 with threads on its inner wall. The threaded cylinder 22 is threadedly connected to the screw 21 at the corresponding position. The outer wall of the bottom end of the screw 21 is connected to a driven gear ring 23. The top surfaces of the bottom measurement module 15 and the middle measurement module 16 have holes on one side of the driven gear ring 23, and a transmission cylinder 25 is rotatably connected to the hole via bearings. The outer wall of the bottom end of the transmission cylinder 25 is connected to a driving gear ring 24, which meshes with the driven gear ring 23 at the corresponding position. The top surface of the transmission cylinder 25 has a slot, and a transmission key 26 is inserted into the slot. The top of the transmission key 26 is connected to the corresponding... The bottom end of the transmission cylinder 25 on the side is connected to the top of the top test module 17. A hole is opened on one side of the top surface of the top test module 17, and the hole is rotatably connected to the transmission key 26 at the top through a bearing. It should be noted that there is at least one middle test module 16. The top surfaces of the bottom test module 15 and the middle test module 16 are connected to the guide cylinder 27 on the opposite side of the transmission cylinder 25. The bottom surfaces of the middle test module 16 and the top test module 17 are connected to the guide rod 28 on the opposite side of the transmission cylinder 25. The top surface of the guide cylinder 27 is opened with a hole that fits the guide rod 28, and the guide rod 28 is sleeved in the guide cylinder 27. The bracket 14 is connected to the motor frame 29 on the side away from the AGV body 10. The motor frame 29 is equipped with a lifting motor 30. The lifting motor 30 is a motor with self-locking and forward and reverse functions. The transmission shaft of the lifting motor 30 is connected to the pulley 31. The bottom end of the bottom transmission cylinder 25 is also connected to the pulley 31. The two pulleys 31 are connected by a transmission belt 32.

[0019] Specifically, the drive gear ring 24 starts and drives the pulley 31 to rotate, which in turn drives the transmission cylinder 25 to rotate via the transmission belt 32. The drive gear ring 24 rotates along with the driven gear ring 23, and the screw 21 rotates with the driven gear ring 23. The threaded cylinder 22, which is threaded to the screw 21, is fixed and therefore moves up and down on the screw 21 as it rotates, thus driving the intermediate measurement module 16 to move up and down to control the distance between it and the bottom measurement module 15. When the intermediate measurement module 16 moves up and down, the transmission key 26 can move up and down within the transmission cylinder 25 to adapt to the change in distance. When the transmission cylinder 25 rotates, it drives the straight transmission key 26 to rotate, which in turn drives the transmission cylinder 25 to rotate together, thereby driving the upper drive gear ring 24 to rotate, which in turn drives the upper threaded cylinder 22 to change the distance between it and the screw 21. This allows for better spacing between intermediate measurement modules 16 and between the intermediate measurement module 16 and the top measurement module 15. The spacing between modules 17 also changes, allowing the warning component 11 to automatically adjust the positions of the middle measurement module 16 and the top measurement module 17 according to the height of the goods, adaptively warning of the risk of the goods falling, tilting, and colliding with obstacles. When the middle measurement module 16 and the top measurement module 17 are raised and lowered, the guide rod 28 adaptively slides in the guide cylinder 27, limiting the angle of the middle measurement module 16 and the top measurement module 17, reducing the thrust on the transmission key 26 in the transmission cylinder 25 when the screw 21 is selected, thereby reducing the friction of the transmission key 26 in the transmission cylinder 25 to facilitate sliding. The lifting motor 30 drives the middle measurement module 16 and the top measurement module 17 to rise synchronously, so that the height of the top measurement module 17 increases to the height range of the middle measurement module 16. According to the height of the goods, the top measurement module 17 is kept corresponding to the top of the goods, and the middle measurement module 16 is kept corresponding to the middle of the goods, and the space occupied is reduced when retracting.

[0020] like Figure 2 , Figure 3 , Figure 5 , Figure 6 Figure 7 and Figure 8As shown, the AGV body 10 is equipped with an expansion component 33 for adjusting the distance between the warning component 11 and the AGV body 10. A support frame 34 is connected to the top surface of the AGV body 10. The support frame 34 has a certain thickness and is adapted to the shape of the AGV body 10 platform. A placement platform 35 is connected to the top surface of the support frame 34. The expansion component 33 includes four guide rails 39, which are respectively connected to the top surface of the AGV body 10 and are located inside the support frame 34. The guide rails 39 are perpendicular to the warning component 11 on the corresponding side. A slide block 40 is slidably connected to the guide rail 39. A fixed shaft 41 with a vertical cross-section of T is connected to the top surface of the slide block 40. A sleeve plate 42 is sleeved on two opposite fixed shafts 41. The top surface of the sleeve plate 42 is open. The AGV body 10 has two oblong holes. A push rod 43 is mounted on the slide 40. The free end of the push rod 43 passes through the support frame 34 and is mounted on the connecting shaft 12. Two fixed shafts 41 are threaded with double-ended screws 38. The two fixed shafts 41 are threaded to the two ends of the double-ended screws 38 respectively. A drive motor 37 is mounted on one side of the AGV body 10. The drive motor 37 is a self-locking and reversible motor. The drive shaft of the drive motor 37 is connected to the double-ended screws 38. A motor compartment 36 is connected to the AGV body 10 to house the drive motor 37. A plug rod 44 is connected to one end of the slide 40 corresponding to the push rod 43. The plug rod 44 has a spiral groove 45. The push rod 43 has a hole at one end corresponding to the plug rod 44 to fit the plug rod 44. The insertion rod 44 is fitted into the hole, and the inner wall of the push rod 43 is connected to the insertion shaft 46. The insertion shaft 46 is spherical and fits the groove size of the spiral groove 45 and is located within the spiral groove 45. The end of the push rod 43 located outside the AGV body 10 is connected to the telescopic plate 47 via a bearing. The telescopic plate 47 is connected to the side of the AGV body 10 corresponding to the limit rod 48. The AGV body 10 has a hole for the limit rod 48 to pass through. One side of the telescopic plate 47 has a groove. The end of the push rod 43 located in the groove is connected to the actuating gear 49. The top surface of the telescopic plate 47 has a hole and inserts an inverted U-shaped gear frame 51. One side of the inner wall of the gear frame 51 has teeth that mesh with the actuating gear 49. The bottom surface of the gear frame 51 is connected to the connecting plate 50. Connected to the connecting shaft 12, the outer wall of the push rod 43 is fitted with a contact spring 52. One end of the push rod 43 located inside the AGV body 10 is provided with an annular protrusion, which abuts against the contact spring 52. The top side of the tooth frame 51 has a hole and a photoelectric sensor 53 is installed in the hole. The photoelectric sensor 53 is used to detect the top position of the goods. The top of the tooth frame 51 is provided with a slanted protrusion. Both the top of the tooth frame 51 and the slanted protrusion are provided with through holes. A convex roller 54 is rotatably connected in the through holes. The outer wall of the convex roller 54 protrudes from the inner wall of the tooth frame 51. Warning rods 55 are connected to both sides of the sleeve 13. The warning rods 55 are bent and adapted to the outer wall of the AGV body 10. The surface of the warning rods 55 is provided with warning components, which are reflective strips or light strips.

[0021] Specifically, under normal conditions, the toothed frame 51 is in a lowered state, allowing the warning component 11 to descend below the placement platform 35, clearing the space around the placement platform 35 and avoiding obstruction and accidental collisions when loading and unloading goods. After the goods are placed on the placement platform 35, the drive motor 37 starts and drives the double-headed screw 38 to rotate. The double-headed screw 38 drives the two sleeve plates 42 to move away from each other. When sliding, the oblong hole on the sleeve plate 42 pushes the slide block 40 to slide on the guide rail 39 through the fixed shaft 41. In the initial state, the push rod 43 is supported by the resisting spring 52. The sliding of the slide block 40 first acts on the insertion rod 44, allowing the insertion rod 44 to be inserted into the push rod 43. During the insertion process, the side wall of the spiral groove 45 acts on the insertion shaft 46, thereby driving the push rod 43 to rotate and push... When lever 43 rotates, it drives the actuating gear 49 to rotate. Then, through meshing with the gear frame 51, it pulls the gear frame 51 upward, thereby driving the entire warning component 11 to rise. When the warning component 11 touches the goods or pallet during its ascent, the convex roller 54 at the top of the gear frame 51 contacts the goods or pallet first, restricting the upward space of the warning component 11. The slide block 40 pushes the push rod 43 through the insert rod 44 and compresses the resisting spring 52. The push rod 43 pushes the warning component 11 to increase the distance between it and the AGV body 10 until the top of the gear frame 51 detaches from the goods or pallet. Then, it adaptively adjusts the distance of the laser grating for goods of different lengths and widths on the AGV body 10, keeping the laser grating around the perimeter of the goods. Then, the gear frame 51 can continue to rise, and the insert rod 44 continues to push. The rod 43 is inserted and drives the push rod 43 to rotate, causing the warning component 11 to continue rising. At this time, the photoelectric sensor 53 abuts against the side of the goods or pallet to reduce friction until the warning component 11 rises to the limit. The bottom measuring module 15 corresponds to the pallet, the middle measuring module 16 and the top measuring module 17 correspond to the middle and top of the goods respectively, and are adapted to the width and thickness of the goods to avoid overexpansion and increase the probability of false alarms. The height of the goods is detected by the photoelectric sensor 53, and the adjustment component controls the position of the middle measuring module 16 and the top measuring module 17 to ensure correspondence with the goods. Through the synchronous performance of the above actions, the accurate correspondence and timely feedback of the laser grating are ensured, and false alarms are avoided. The drive motor 37 drives the double-headed screw 38 to rotate, causing the two sleeve plates 42 to move closer to each other. When the toothed frame 51 contacts the cargo or pallet via the photoelectric sensor 53, the sleeve 42 is restricted and cannot reset. The slide 40 first pulls the insert rod 44 out from the push rod 43, causing the push rod 43 to rotate and drive the warning component 11 down until it is below the cargo. Then, the warning component 11 can move towards the AGV body 10. During the retraction of the slide 40, the push rod 43 resets through the release of the contact spring 52 and pulls the warning component 11 to the initial position until the contact spring 52 has completed its release. In conjunction with the adjustment component, the warning component 11 can be arranged around the AGV body 10 while being stored under the placement platform 35. When the warning component 11 expands, the warning rod 55 expands accordingly, using the warning component to indicate the size range of the cargo.This serves to remind personnel of the dimensions of goods within a certain range to prevent collisions.

[0022] Working principle: Before use: Place the goods on the placement platform 35.

[0023] In use: First, the expansion component 33 is activated, which first drives the warning component 11 to rise. When the warning component 11 comes into contact with the goods during the rising process, the rise of the warning component 11 is restricted. The expansion component 33 automatically switches to the expansion function, allowing the warning component 11 to expand along the goods. When the warning component 11 expands to the outside of the goods, the rise of the warning component 11 is unrestricted. The expansion component 33 automatically switches to the lifting function, allowing the warning component 11 to rise to a position above the placement platform 35. At this time, the warning component 11 corresponds to the periphery of the goods.

[0024] The second step is to adjust the components to raise the middle measurement module 16 and the top measurement module 17, so that the top measurement module 17 corresponds to the top of the goods and the middle measurement module 16 corresponds to the middle of the goods.

[0025] The third step is to activate the warning component 11, which causes the laser emitter 19 to emit a laser, which is received by the laser receiver 20 on the opposite side to form a laser grating, providing warnings of obstacles around the cargo and the cargo's own deviation.

[0026] After use: Turn off the warning component 11, adjust the component control to lower and reset the middle measurement module 16 and top measurement module 17, and control the expansion component 33 to lower the warning component 11. After the warning component 11 is lowered below the goods, pull the warning component 11 closer to the AGV body 10. After the slide 40 is reset to the initial position, the pulled rod 44 and the photoelectric sensor 53 pushed by the energy released by the resisting spring 52 are also reset to the initial position. The warning component 11 is close to the AGV body 10 and placed under the placement platform 35 to ensure stable implementation of the unloading action.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
