Description

Technical Field

[0001] This invention relates to the field of inspection drone delivery, and more particularly to an assembly system for inspection drones used for highway infrastructure. Background Technology

[0002] An existing patent (publication number: CN205346021U) proposes a PCB board conveying mechanism, including two symmetrically arranged conveyor rails, two conveyor belts, and a driving device. The conveyor rails are arranged along the conveying direction of the PCB board, and the conveyor belts are located on the inner sidewalls of the two conveyor rails. The top of the conveying surface formed by the conveyor belt is located below the PCB board, and the width of the conveying surface is greater than the width of the PCB board. However, this device "uses the friction between the conveyor belt and the bottom surface of the PCB board to drive the PCB board forward when the PCB board is placed flat on the conveyor belt." During the PCB board conveying process, it may be contaminated by dust and other debris, affecting the yield of the finished product in subsequent processing. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a highway roadside facility inspection drone assembly system that increases the conveying efficiency of drone PCB boards, while also straightening misaligned drone PCB boards for easier subsequent positioning and cleaning operations. This system synchronizes the forward speed of the cleaning carrier with the conveying speed of the drone PCB conveyor belt, thereby increasing the yield of finished products in subsequent processing.

[0004] The objective of this invention is achieved through the following technical solution: A drone assembly system for inspecting roadside facilities includes a drone PCB conveyor belt and drone PCB boards. The drone PCB conveyor belt continuously transports the drone PCB boards and also provides support for various mechanisms that clean the drone PCB boards. The conveyor belt has support rod clearance slots evenly arranged inside. A synchronous drive mechanism is located at the bottom of the conveyor belt, which synchronously lifts the drone PCB boards placed on it, allowing the cleaning operation to be completed while the boards are continuously transported. An auxiliary positioning mechanism is located outside the synchronous drive mechanism, which clamps certain parts of the mechanism to prevent excessive stress on components during cleaning, thus extending their lifespan. A cleaning mechanism is located inside the synchronous drive mechanism to clean the drone PCB boards.

[0005] The synchronous drive mechanism includes a dust extraction pipe, a cleaning support shell, a support wheel, a support platform rod, a labyrinth groove driven rod, a threaded groove connecting block, and a synchronous drive screw. The drone PCB conveyor belt has a bottom support foot, and a side positioning rail on the side of the bottom support foot. A cleaning support shell is located on the upper part of the drone PCB conveyor belt. A transition support column is located at the bottom of the cleaning support shell, and a rail connecting foot is located at the bottom of the transition support column. The rail connecting foot is pressed against the side of the side positioning rail. The support wheel is rotatably connected to the rail connecting foot, and the support wheel is pressed against the upper part of the side positioning rail. Motor mounting platforms and transition supports are located on both sides of the drone PCB conveyor belt. The column has a drive rod clearance groove on the side away from the motor mounting platform, and a drive rod mounting platform on the side of the transition support column closest to the motor mounting platform. The drive rod clearance groove corresponds to the position of the drive rod mounting platform, and the inner diameter of the drive rod clearance groove is larger than the inner diameter of the drive rod mounting platform. The screw drive motor is inserted into the motor mounting platform and fixed. The drive shaft of the screw drive motor is fixedly connected to the synchronous drive screw. The synchronous drive screw is adapted to the drive rod mounting platform and is connected to the drive rod mounting platform. The synchronous drive screw rotates inside the drive rod mounting platform. The top of the drive rod mounting platform has a driven block mounting platform, and the driven block mounting platform has a screw groove block mounting column inside.

[0006] The bottom of the screw mounting post is rotatably connected to the threaded groove connecting block. The surface of the synchronous drive screw has a drive screw groove, which consists of a backward drive helical groove and a forward drive helical groove. The backward drive helical groove and the forward drive helical groove are connected end to end. The backward drive helical groove has a smaller pitch, and the forward drive helical groove has a larger pitch. The threaded groove connecting block is adapted to the drive screw groove and connects to the drive screw groove. The threaded groove connecting block slides inside the drive screw groove. The middle of the track connecting support foot has a linkage rod bearing post, and the middle of the linkage rod bearing post has a linkage rod mounting block. A bearing platform support rod is set at the bottom of the clean bearing shell. The bearing platform support rod corresponds to the position of the support rod clearance groove. The width of the support rod clearance groove is greater than the width of the bearing platform support rod. The top of the bearing platform support rod has... The lifting PCB board carrier platform is designed with an incline. The side of the lifting PCB board carrier platform that is in the same direction as the drone's PCB board transport is lower, while the side that is in the opposite direction is higher. The carrier shell has an incline mounting slot, and the top of the incline mounting slot has a dust extraction pipe mounting slot. The dust extraction pipe is inserted into the dust extraction pipe mounting slot and fixed. The end of the dust extraction pipe is connected to an air pump. The bottom of the incline mounting slot has a PCB board carrier platform connecting slot, which is adapted to the lifting PCB board carrier platform. The lifting PCB board carrier platform is inserted into the PCB board carrier platform connecting slot.

[0007] Beneficial effects: 1. The lifting PCB board support platform of this invention is designed with an inclination, so that the PCB board of the drone will slide down to a certain extent during the process of the lifting PCB board support platform lifting the drone PCB board, so that the drone PCB board is pressed against the side of the lifting PCB board support platform to complete the initial positioning. At the same time, it can also straighten the drone PCB board that is not placed correctly, which facilitates subsequent positioning and cleaning operations and improves the efficiency of conveying and assembling drones for highway facility inspection.

[0008] 2. This invention uses a high-position and a low-position clamping block support platform to position and support the lifting PCB board support platform. This ensures the accuracy of the positioning of the lifting PCB board support platform and ensures that the force on the drone PCB board and the lifting PCB board support platform during the subsequent cleaning of the drone PCB board is ultimately transmitted to the low-position and high-position clamping block support platforms. The force transmission distance is short, reducing the possibility of vibration and displacement during transmission, making the subsequent cleaning process of the drone PCB board more stable and improving the assembly accuracy of the drone for inspecting highway facilities.

[0009] 3. This invention also uses a high-position card block support platform and a low-position card block support platform to position and support the lifting PCB board support platform. This allows the weight of the support platform support rods and other parts to be supported by the cleaning support shell during the cleaning process. This prevents the downward force generated by the support platform support rods due to their own weight from being transmitted downwards to the connection between the labyrinth groove driven rod and the labyrinth rod mounting slot, as well as the connection between the labyrinth grooves and the labyrinth groove driven rods. This reduces the force experienced by the labyrinth groove driven rods, the connection between the labyrinth rod mounting slots, and the connection between the labyrinth grooves and the labyrinth groove driven rods during the cleaning process, reduces wear between the contact surfaces of various parts, and extends the service life of each part.

[0010] 4. The drive screw groove of this invention is composed of a backward drive screw groove and a forward drive screw groove connected end to end. The forward drive screw groove adopts a large pitch design, so that the forward speed of the cleaning carrier shell is synchronized with the conveying speed of the UAV PCB conveyor belt. Thus, the cleaning operation is completed simultaneously while the UAV PCB board is continuously conveyed. There is no need to stop the UAV PCB conveyor belt during the cleaning process, resulting in higher cleaning efficiency, better cleaning effect, and improved efficiency of conveying and assembling UAVs for highway facility inspection.

[0011] 5. The backward drive spiral groove of this invention adopts a small pitch design, thereby reducing the retraction speed of the cleaning carrier shell. This allows the cleaning carrier shell to skip the next UAV PCB board and correspond to the next UAV PCB board during retraction. At the same time, by setting up two sets of synchronous drive mechanisms, auxiliary positioning mechanisms, and cleaning mechanisms, the cleaning operation of all UAV PCB boards can be realized. The two sets of synchronous drive mechanisms, auxiliary positioning mechanisms, and cleaning mechanisms perform cleaning operations on the UAV PCB boards, enabling high-speed transmission of the UAV PCB boards, further increasing the transmission efficiency of the UAV PCB boards, reducing the speed requirement during the retraction of the cleaning carrier shell, reducing the impact between various parts inside the cleaning carrier shell during acceleration and deceleration during the retraction process, improving the assembly efficiency of highway facility inspection UAVs, and thus reducing the overall failure rate.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A drone assembly system for inspecting roadside facilities includes a drone PCB conveyor belt 1 and a drone PCB board 16. The drone PCB conveyor belt 1 continuously conveys the drone PCB board 16 and also provides support for various mechanisms that clean the drone PCB board 16. The drone PCB conveyor belt 1 has support rod clearance grooves 28 evenly arranged inside. A synchronous drive mechanism 3 is located at the bottom of the drone PCB conveyor belt 1, which synchronously lifts the drone PCB board 16 placed on the conveyor belt 1, allowing the drone PCB board 16 to complete the cleaning operation while being continuously conveyed. An auxiliary positioning mechanism 4 is located on the outside of the synchronous drive mechanism 3, which clamps some parts of the synchronous drive mechanism 3 to prevent excessive stress on some components during the cleaning process, thus affecting their service life. A cleaning mechanism 5 is located inside the synchronous drive mechanism 3, which performs cleaning operations on the drone PCB board 16.

[0030] Example 2: The synchronous drive mechanism 3 of this invention includes a dust extraction pipe 11, a cleaning support shell 13, a support wheel 22, a support platform support rod 23, a labyrinth groove driven rod 41, a threaded groove connecting block 45, and a synchronous drive screw 86. The drone PCB conveyor belt 1 has a bottom support foot 14 at its bottom, and a side positioning rail 15 on the side of the bottom support foot 14. The cleaning support shell 13 is provided on the upper part of the drone PCB conveyor belt 1.

Motors are mounted on both sides of the drone PCB conveyor belt 1. Platform 19, transition support column 84 has a drive rod clearance groove 18 on the side away from motor mounting platform 19, and a drive rod mounting platform 42 on the side of transition support column 84 close to motor mounting platform 19.

Screw drive motor 85 is inserted into and fixed inside motor mounting platform 19. The drive shaft of screw drive motor 85 is fixedly connected to synchronous drive screw 86. Synchronous drive screw 86 is adapted to drive rod mounting platform 42 and connected to drive rod mounting platform 42. Synchronous drive screw 86 rotates inside drive rod mounting platform 42. Driven block mounting platform 21 is located on the top of drive rod mounting platform 42. 1. An internal threaded groove block mounting post 44 is provided. The bottom of the threaded groove block mounting post 44 is rotatably connected to the threaded groove connecting block 45. The surface of the synchronous drive screw 86 has a drive screw groove 17, which is composed of a backward drive helical groove 171 and a forward drive helical groove 172. The backward drive helical groove 171 and the forward drive helical groove 172 are connected end to end. The backward drive helical groove 171 has a smaller pitch, and the forward drive helical groove 172 has a larger pitch. The threaded groove connecting block 45 is adapted to the drive screw groove 17 and connects to the drive screw groove 17. The threaded groove connecting block 45 slides inside the drive screw groove 17. The middle of the track connecting support 46 has a linkage rod bearing post 26, and the middle of the linkage rod bearing post 26 has a linkage rod mounting block 27. Clean the bearing shell 13. A support rod 23 is provided at the bottom, and the support rod 23 corresponds to the support rod clearance groove 28. The width of the support rod clearance groove 28 is greater than the width of the support rod 23. The top of the support rod 23 has a lifting PCB board support platform 65. The lifting PCB board support platform 65 is tilted. The side of the lifting PCB board support platform 65 that is in the same direction as the conveying direction of the drone PCB board 16 is lower, and the side of the lifting PCB board support platform 65 that is in the opposite direction to the conveying direction of the drone PCB board 16 is higher. The interior of the cleaning support shell 13 has a tilting platform mounting groove 67. The top of the tilting platform mounting groove 67 has a dust extraction pipe mounting groove 32. The dust extraction pipe 11 is inserted into the dust extraction pipe mounting groove 32 and fixed. The end of the dust extraction pipe 11 is connected to a suction pump.The bottom of the tilting platform mounting slot 67 has a PCB board support platform connecting slot 75, which is adapted to the lifting PCB board support platform 65. The PCB board support platform connecting slot 75 connects to the lifting PCB board support platform 65, and the lifting PCB board support platform 65 is inserted into the PCB board support platform connecting slot 75. The bottom of the support platform support rod 23 has a maze block mounting platform 24, and the bottom of the maze block mounting platform 24 has a support rod linkage rod 25, which is adapted to the linkage rod mounting block 27. The support rod linkage rod 25 connects to the support platform support rod 27. Connecting to the linkage rod mounting block 27, the bearing linkage rod 25 slides inside the linkage rod mounting block 27. The maze block mounting platform 24 has maze rod mounting slots 43 on both sides, which are adapted to the maze groove driven rod 41. The maze rod mounting slots 43 connect to the maze groove driven rod 41, which slides inside the maze rod mounting slots 43. The ends of the maze groove driven rod 41 and the maze rod mounting slots 43 are connected by springs. The UAV PCB conveyor belt 1 has maze groove bearing platforms 38 on both sides, which connect to the maze block mounting platform 2. 4. Corresponding to the position, the inner side of the maze groove support platform 38 has a maze groove 39. The maze groove 39 is adapted to the maze groove driven rod 41. The maze groove 39 is connected to the maze groove driven rod 41. The maze groove driven rod 41 slides inside the maze groove 39. The maze groove 39 is composed of a first slide groove 391, a second slide groove 392, a vertical descending groove 393, an inclined ascending groove 394, and a check platform 395. The first slide groove 391 and the second slide groove 392 are both horizontal straight grooves. The inclined ascending groove 394 is an inclined groove with an inclination angle of 135°. The top of the inclined ascending groove 394 is connected to the second slide groove 391. The starting end of chute 392 is connected; the bottom of inclined ascending chute 394 is connected to the middle of chute 391; vertical descending chute 393 is a 90° vertical chute; the top of vertical descending chute 393 is connected to the end of chute 392; the bottom of vertical descending chute 393 is connected to the end of chute 391; a check platform 395 is provided at the connection between inclined ascending chute 394 and chute 391. The side of check platform 395 facing the starting end of chute 391 is a vertical plane, and the side of check platform 395 away from the starting end of chute 391 is an inclined plane.

[0031] Furthermore, the screw drive motor 85 drives the synchronous drive screw 86 to rotate, causing the drive screw groove 17 on the surface of the synchronous drive screw 86 to move the drive thread groove connecting block 45, thereby driving the cleaning carrier shell 13 and the mechanism it supports to perform back-and-forth cyclical motion. During the forward movement of the cleaning carrier shell 13, the labyrinth groove driven rod 41 passes through the first slide groove 391, the inclined rising groove 394, and finally enters the interior of the second slide groove 392, causing the carrier support rod 23 to gradually rise during the forward movement. This causes the lifting PCB board carrier 65 of the carrier support rod 23 to extend from inside the UAV PCB conveyor belt 1, placing the PCB board carrier 65 into the UAV PCB conveyor belt 1. The drone PCB board 16 is lifted from the upper part of the drone PCB conveyor belt 1 until the lifting PCB board support platform 65 is inserted into the PCB board support platform connecting groove 75 to complete the positioning. After the cleaning operation of the drone PCB board 16 is completed, the labyrinth chute driven rod 41 enters the vertical descent groove 393 and descends, causing the lifting PCB board support platform 65 to sink back into the drone PCB conveyor belt 1, so that the drone PCB board 16 is put back into the upper part of the drone PCB conveyor belt 1 for continued conveying. The labyrinth chute driven rod 41 enters the first slide 391 and moves backward to enter the next cleaning cycle.

[0032] It should be noted that the lifting PCB board support platform 65 is tilted, which causes the drone PCB board 16 to slide down to a certain extent during the process of lifting the drone PCB board 16. This presses the drone PCB board 16 against the side of the lifting PCB board support platform 65 to complete the initial positioning. At the same time, it can also straighten any drone PCB boards that are not properly positioned, which facilitates subsequent positioning and cleaning operations and improves the efficiency of transporting and assembling drones for highway facility inspection.

[0033] Example 3: The auxiliary positioning mechanism 4 of this invention includes a lifting hydraulic cylinder 36, a clamping drive plate 37, a low-position positioning block 49, a low-position drive linkage 52, a low-position clamping block support platform 53, a high-position positioning block 58, and a high-position clamping block support platform 62. The side of the cleaning support shell 13 that is in the same direction as the conveying direction of the UAV PCB board 16 has a low-position positioning slide 48, a side positioning post mounting platform 29, and a low-position positioning post mounting groove 83. The low-position positioning slide 48 is located in the center, the side positioning post mounting platforms 29 are distributed on both sides of the low-position positioning slide 48, and the low-position positioning post mounting groove 83 is located at the lower part of the low-position positioning slide 48. The low-position positioning block 49 is adapted to the low-position positioning slide 48 and is connected to the low-position positioning slide 48. The lower positioning block 49 has side positioning posts 31 on both sides, which are adapted to the side positioning post mounting platform 29. The side positioning posts 31 are connected to the side positioning post mounting platform 29 and slide inside the side positioning post mounting platform 29. The side positioning post mounting platform 29 is connected to the lower positioning block 49 by a spring. The lower positioning block 49 has an upper lower connecting rod mounting platform 51 on the side away from the cleaning carrier shell 13. The lower positioning block 49 has a lower locking block carrier platform 53 at the bottom. The lower locking block carrier platform 53 has a lower lower connecting rod mounting platform 54 on the side away from the cleaning carrier shell 13. The top of the lower driving connecting rod 52 is rotatably connected to the upper lower connecting rod mounting platform 51, and the bottom of the lower driving connecting rod 52 is rotatably connected to the lower lower connecting rod mounting platform 54. Next, the low-position block support platform 53 has a low-position positioning post 81 on the side facing the cleaning support shell 13, and the lifting PCB board support platform 65 has a low-position positioning groove 79 on the side facing the low-position block support platform 53. The low-position positioning post 81 is adapted to the low-position positioning post mounting groove 83 and the low-position positioning groove 79. The low-position positioning post 81 is connected to the low-position positioning post mounting groove 83 and the low-position positioning groove 79 in sequence. The low-position positioning post 81 passes through the low-position positioning post mounting groove 83 and is inserted into the low-position positioning groove 79. The side of the cleaning support shell 13 opposite to the conveying direction of the UAV PCB board 16 has a high-position positioning slide 55 and a high-position block mounting platform 61. The high-position positioning slide 55 is in a central position, and the high-position block mounting platform 61 is located below the high-position positioning slide 55. The high-positioning block 58 is adapted to the high-positioning slide rail 55 and is connected to the high-positioning slide rail 55. The high-positioning block 58 slides outside the high-positioning slide rail 55. The side of the high-positioning block 58 away from the cleaning support shell 13 has an upper high-positioning connecting rod mounting platform 59. The high-positioning locking block support platform 62 is adapted to the high-positioning locking block mounting platform 61 and is connected to the high-positioning locking block mounting platform 61. The high-positioning locking block support platform 62 slides inside the high-positioning locking block mounting platform 61. The side of the high-positioning locking block support platform 62 facing the upper high-positioning connecting rod mounting platform 59 has a lower high-positioning connecting rod mounting platform 63. The top of the high-positioning drive connecting rod 78 is rotatably connected to the upper high-positioning connecting rod mounting platform 59, and the bottom of the high-positioning drive connecting rod 78 is rotatably connected to the lower high-positioning connecting rod mounting platform 63.On the side opposite to the high-position clamping block support platform 62 and the lower high-position connecting rod mounting platform 63, there is a high-position positioning column 76 and a lower auxiliary support block 64. The lower auxiliary support block 64 is located below the high-position positioning column 76 and is pressed against the lower side of the lifting PCB board support platform 65. The side of the lifting PCB board support platform 65 facing the high-position clamping block support platform 62 has a high-position positioning groove 82. The high-position positioning column 76 is adapted to the high-position positioning groove 82 and is connected to the high-position positioning groove 82. The high-position positioning column 76 is inserted into the high-position positioning groove 82. The top of the cleaning support shell 13 has a drive plate support platform 33. The top of the drive plate support platform 33 has a drive plate support column 34. The top of the drive plate support column 34 has a hydraulic cylinder mounting platform 35. A lifting hydraulic cylinder 36 is fixedly connected to the lower part of the unit. The lower part of the lifting hydraulic cylinder 36 has a telescopic hydraulic rod 72. A clamping drive plate 37 is fixedly connected to the middle of the telescopic hydraulic rod 72. The surface of the clamping drive plate 37 has a drive plate bearing column mounting groove 47, which is adapted to the drive plate bearing column 34. The drive plate bearing column mounting groove 47 connects to the drive plate bearing column 34 and slides outside the drive plate bearing column 34. The clamping drive plate 37 has a low-position drive support leg 57 on the side facing the low-position positioning block 49, with its bottom pressing against the upper part of the low-position positioning block 49. The clamping drive plate 37 also has a high-position drive support leg 56 on the side facing the high-position positioning block 58, with its bottom fixedly connected to the high-position positioning block 58.

[0034] Furthermore, after the lifting PCB board support platform 65 is inserted into the PCB board support platform connecting groove 75, the telescopic hydraulic rod 72 drives the clamping drive plate 37 to descend. When the clamping drive plate 37 descends, the transmission mechanism consisting of the high-position drive support leg 56, the high-position positioning block 58, the high-position drive connecting rod 78, and the high-position clamping block support platform 62 controls the high-position clamping block support platform 62 to approach the lifting PCB board support platform 65, so that the lower auxiliary support block 64 is pressed against the lower part of the lifting PCB board support platform 65, and the high-position clamping block support platform 62 is lifted. The high positioning column 76 of the platform 62 is inserted into the high positioning groove 82 of the lifting PCB board carrier platform 65. Simultaneously, when the clamping drive plate 37 moves downward, the transmission mechanism consisting of the low driving support 57, the low positioning block 49, the low driving connecting rod 52, and the low clamping block carrier platform 53 controls the low positioning column 81 of the low clamping block carrier platform 53 to be inserted into the low positioning groove 79 of the lifting PCB board carrier platform 65, thereby completing the positioning of the lifting PCB board carrier platform 65.

[0035] It should be noted that the high-position card block support platform 62 and the low-position card block support platform 53 provide positioning support for the lifting PCB board support platform 65. This ensures the accuracy of the positioning of the lifting PCB board support platform 65 and ensures that the force on the drone PCB board 16 and the lifting PCB board support platform 65 during the subsequent cleaning of the drone PCB board is ultimately transmitted to the low-position card block support platform 53 and the high-position card block support platform 62. The force transmission distance is short, reducing the possibility of vibration and displacement during the transmission process, and making the subsequent cleaning process of the drone PCB board 16 more stable.

[0036] It should also be noted that the high-position card block support platform 62 and the low-position card block support platform 53 provide positioning support for the lifting PCB board support platform 65, so that the mass of the support platform support rod 23 and other parts is supported by the cleaning support shell 13 during the cleaning process. This prevents the downward force generated by the support platform support rod 23 due to its own mass from being transmitted downward to the connection between the labyrinth groove driven rod 41 and the labyrinth rod mounting groove 43, as well as the connection between the labyrinth groove 39 and the labyrinth groove driven rod 41. This reduces the force experienced by the labyrinth groove driven rod 41, the connection between the labyrinth rod mounting groove 43, and the connection between the labyrinth groove 39 and the labyrinth groove driven rod 41 during the cleaning process, reduces wear between the contact surfaces of various parts, and extends the service life of each part.

[0037] Example 4: The cleaning mechanism 5 of this invention includes an inclined cleaning platform 66, an electric telescopic rod 71, a cleaning brush 77, and a cleaning motor 693. The inclined platform mounting groove 67 is adapted to the inclined cleaning platform 66, and the inclined cleaning platform 66 is connected to the inclined platform mounting groove 67, sliding within the inclined platform mounting groove 67. The top of the inclined cleaning platform 66 has an inclined platform drive slide 74, and the bottom of the telescopic hydraulic rod 72 has an inclined platform drive block 73, adapted to the inclined platform drive slide 74, connected to the inclined platform drive slide 74, and sliding outside the inclined platform drive slide 74. The side of the inclined cleaning platform 66 facing the high-positioning block 58 has a rear PCB board positioning platform 663, the bottom of which has a rear inclined guide slope 664. The bottom of the inclined cleaning platform 66 has a side PCB board positioning platform 661, located on both sides of the rear PCB board positioning platform 663. The bottom has a side-tilting guide surface 662. The drone PCB board 16 is placed on the upper part of the lifting PCB board support platform 65. The rear PCB board positioning platform 663 and the side PCB board positioning platform 661 are pressed against the side of the drone PCB board 16. The surface of the tilting cleaning platform 66 has a cleaning component mounting groove 68. The top of the tilting cleaning platform 66 is fixedly connected to the electric telescopic rod 71. The bottom of the electric telescopic rod 71 is provided with a cleaning component 69. The cleaning component 69 is adapted to the cleaning component mounting groove 68 and is connected to the cleaning component mounting groove 68. The cleaning component 69 slides inside the cleaning component mounting groove 68. The cleaning component 69 is composed of a cleaning telescopic rod 691, a cleaning motor mounting platform 692, and a cleaning motor 693. The bottom of the electric telescopic rod 71 has a cleaning telescopic rod 691. The side of the cleaning telescopic rod 691 has a cleaning motor mounting platform 692. The side of the cleaning motor mounting platform 692 is fixedly connected to the cleaning motor 693. The bottom of the cleaning motor 693 has a drive shaft that is fixedly connected to a cleaning brush 77.

[0038] It should be noted that the drive screw groove 17 is composed of a backward drive screw groove 171 and a forward drive screw groove 172 connected end to end. The forward drive screw groove 172 adopts a large pitch design, which makes the forward speed of the cleaning carrier shell 13 synchronize with the conveying speed of the UAV PCB conveyor belt 1. Thus, the cleaning operation is completed simultaneously while the UAV PCB board 16 is continuously conveyed. There is no need to stop the UAV PCB conveyor belt 1 during the cleaning process, resulting in higher cleaning efficiency, better cleaning effect, and improved assembly efficiency of UAVs for inspecting highway facilities.

[0039] It should be noted that the retraction drive spiral groove 171 adopts a small pitch design, thereby reducing the retraction speed of the cleaning carrier shell 13. This allows the cleaning carrier shell 13 to skip the next UAV PCB board 16 and correspond to the next UAV PCB board 16 during retraction. At the same time, by setting two sets of synchronous drive mechanisms 3, auxiliary positioning mechanisms 4, and cleaning mechanisms 5, the cleaning operation of all UAV PCB boards 16 can be realized. The two sets of synchronous drive mechanisms 3, auxiliary positioning mechanisms 4, and cleaning mechanisms 5 perform the cleaning operation of the UAV PCB boards 16, enabling the UAV PCB boards 16 to be transported at high speed, further increasing the transport efficiency of the UAV PCB boards 16, reducing the speed requirement of the cleaning carrier shell 13 during retraction, and reducing the impact between the various parts inside the cleaning carrier shell 13 during acceleration and deceleration during the retraction process, thereby reducing the overall failure rate.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
