[0017] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The first embodiment of the present invention provides a heavy-duty flexible assembly platform for unmanned aerial vehicle (UAV) assembly, such as... Figure 1-3 As shown, the device includes a support frame 1, with a moving mechanism connected to the bottom of the support frame 1, and a housing 51 covering the outside of the support frame 1. Along the length of the housing 51, a first support assembly 52 for placing the drone's nose, two symmetrically distributed second support assemblies 53, and two symmetrically distributed clamping and locking mechanisms 7 are sequentially arranged. The distance between the two clamping and locking mechanisms 7 is greater than the distance between the two second support assemblies 53. The first support assembly 52 includes a U-shaped support frame 521, with a first support sleeve 522 connected to the open end of the support frame 521. A first guide rod 523 is fixed inside the first support sleeve 522, and a first support elastic element 524 is sleeved on the side wall of the first guide rod 523. A groove 5211 is provided along the circumference of the first support sleeve 522, and a second support plate 525 is slidably connected to the groove 5211. The two ends of the first support elastic member 524 abut against the second support plate 525 and the first support sleeve 522 respectively. A sliding notch 5213 is provided along the axial direction of the first support sleeve 522, and a locking notch 5212 is provided along the circumference of the first support sleeve 522. The sliding notch 5213 and the locking notch 5212 are connected. The second support plate 525 can rotate along the groove 5211 to the position of the sliding notch 5213, and move downward along the sliding notch 5213 to the position of the locking notch 5212, and rotate the second support plate 525 to make it fit into the locking notch 5212.

[0020] When it is necessary to lock the drone, the drone is placed inside the silicone plate. With the front end of the drone locked by the first silicone block, the drone will not move. At the same time, the first silicone block drives the support block to slide upward and compresses the second support elastic element within the second support plate 525. Since the second support plate 525 is stuck inside the slide groove 5211, it can prevent the second support plate 525 from sliding accidentally. When it is necessary to adjust the height of the second support plate 525, rotate the second support plate 525 along the slide groove 5211 to the position of the sliding notch 5213, and move it downward along the sliding notch 5213 to the position of the locking notch 5212. Then rotate the second support plate 525 to make it engage with the locking notch 5212.

[0021] In an exemplary embodiment, the width of the sliding notch 5213 is equal to the width of the second support plate 525, and the height of the locking notch 5212 is greater than or equal to the thickness of the second support plate 525, ensuring that the second support plate 525 can slide along the sliding notch 5213 and engage with the locking notch 5212. A groove is provided on the second support plate 525, and a second support elastic member 526 is disposed within the groove. A support block 527 is connected to the bottom of the second support plate 525, and the second support elastic member 526 is located above the support block 527. A first silicone block 528 is connected to the bottom of the support block 527. The support block 527 and the first silicone block 528 are located outside the first support sleeve 522. When the second support plate 525 rotates, the support block 527 and the first silicone block 528 will not contact the first support sleeve 522, thereby affecting the rotation and sliding of the second support plate 525. A silicone plate 529 is disposed on the inner side of the support frame 521, and the support frame 521 and the silicone plate 529 are connected by a threaded rod 5210. The silicone plate 529 can be fitted to the bottom of the drone's nose, and the silicone plate 529 can be replaced according to the size of the drone.

[0022] Furthermore, an opening is formed at one end of the housing 51, and a third support plate 54 is connected to the opening. The width of the third support plate 54 is greater than the width of the housing 51, and the surface height of the third support plate 54 is higher than the surface height of the housing 51. A step is formed at the connection between the third support plate 54 and the housing 51. The second support assembly 53 and the clamping and locking mechanism 7 are fixed on the third support plate 54.

[0023] Furthermore, the third support plate 54 is U-shaped, with its open end located away from the first support component 5. The second support component 53 is fixed to the bottom of the third support plate 54, and two clamping and locking mechanisms 7 are respectively fixed to the side walls of the third support plate 54. A sealing plate 6 is fixedly connected inside the support frame 1, located below the open end of the third support plate 54. The support frame 1 has a reserved space for the AGV to enter. The sealing plate 6 is a top sealing partition of this internal space, completely separating the UAV assembly area above from the walking channel below for the AGV to enter and lift. This prevents foreign objects such as bolts, tools, and metal scraps generated during assembly from falling into the AGV running track or lifting mechanism, thereby ensuring the AGV's operational safety and positioning accuracy in the underground channel.

[0024] For example, such as Figure 4As shown, the second support assembly 53 includes a second support sleeve 531, which is fixed to the surface of the third support plate 54. A first sliding block 532 is sleeved inside the second support sleeve 531, and a third support elastic element 534 is disposed between the first sliding block 532 and the third support plate 54. A second silicone block 533 is disposed on the surface of the first sliding block 532. When supporting the drone, the first sliding block 532 slides downward along the second support sleeve 531 and compresses the third support elastic element 534, adaptively adjusting the support height according to the operating load to ensure uniform force distribution in the middle of the drone body.

[0025] like Figure 5 As shown, the clamping and locking mechanism 7 includes a sleeve 711, inside which a second guide rod 712 is provided. The sleeve 711 and the second guide rod 712 are fixed on the third support plate 54. The second guide rod 712 is sequentially sleeved with a first limiting elastic member 714 and a second sliding block 713 from bottom to top. A first sliding through hole is provided circumferentially along the side wall of the sleeve 711. The second sliding block 713 extends out of the first sliding through hole and is connected to a U-shaped clamping frame 721. The open ends of the clamping frame 721 are connected to two baffles facing each other. The two inner side walls of the clamping frame 721 are respectively connected to sliding silicone baffles 723 through auxiliary elastic members 722. The sliding silicone baffles 723 are located inside the baffles. Limiting notches 724 are provided at intervals on the side wall of the sleeve 711. When the limiting plate is inserted into the limiting notch 724 and positioned above the second sliding block 713, it can prevent the second sliding block 713 from sliding back to its original position. The limiting plate and limiting notch 724 work together to fix the height and adapt to drones of different sizes; by inserting the external structure on both sides of the fuselage into the two sliding silicone baffles 723, the sliding silicone baffles 723 conform to the contour of the fuselage under the action of the auxiliary elastic element 722, the clamping frame 721 ensures stable clamping and achieves full flexible contact to avoid damage to the surface of the drone, and ensures that the external structure does not shift during the final assembly process.

[0026] In an exemplary embodiment, the moving mechanism includes a first support plate 2, which is connected to the bottom of the support frame 1, and a support rod 3 is connected between the first support plate 2 and the support frame 1; a caster wheel 4 and a brake locking assembly 8 are connected to the bottom of the first support plate 2.

[0027] Specifically, the brake locking assembly includes a support column 82, a first magnet 84 disposed inside the support column 82, a support sleeve 81 sleeved around the support column 82, a sliding plate 89 connected to the top of the support column 82, the sliding plate being located between the support column 82 and the support sleeve 81 and slidably connected to the support sleeve 81; the top of the support sleeve 81 is fixed to the first support plate 2; a second sliding through hole is formed on the support sleeve 81, a pedal 83 is connected to the support sleeve 81, and the pedal 83 extends out of the second sliding through hole; a... A support ring plate 810 is located outside the support column 82. A second limiting elastic element 85 is provided between the support ring plate 810 and the sliding plate. An annular groove is formed between the support ring plate 810 and the bottom of the support sleeve 81. A second magnet 86 is provided in the annular groove. A sliding rod 88 is fixed on the second magnet 86. The free end of the sliding rod 88 extends out of the support sleeve 81. A third limiting elastic element 87 is sleeved on the sliding rod 88. The third limiting elastic element 87 is located between the second magnet 86 and the support sleeve 81. A base 811 is connected to the bottom of the support column 82. The base 811 is located below the support sleeve 81.

[0028] When locking is required, press down on pedal 83 to move support column 82 downward along support sleeve 81 closer to the ground, lift caster wheel off the ground and fix platform at work station reference position, first magnet 84 approaches second magnet 86 to achieve adsorption locking; when unlocking is required, pull sliding rod 88 to separate second magnet 86 from first magnet 84, third limiting elastic element 87 resets support column 82, caster wheel resumes free rotation.

[0029] In this embodiment, by placing the drone inside the silicone plate 529 and at the top of the second silicone block 533 and the first sliding block 532, and the first sliding block 532 sliding downwards, the second support plate 525 and the first support elastic member 524 are pressed against the top of the drone, thereby achieving the effect of locking the drone on the assembly platform. Through bottom support, front end pressing and middle support, the drone achieves full flexible contact to ensure assembly accuracy and protect precision surfaces, and is compatible with the final assembly of multiple models and weights of drones. The external structure of the drone is placed inside two sliding silicone baffles 723. The sliding silicone baffles 723 compress the auxiliary elastic element 722 and, supported by the sleeve 711, prevent the second sliding block 713 and the clamping frame 721 from sliding downward, thereby locking the external structure of the drone. The sliding silicone baffles 723 adapt to the external contour of the drone body under the action of the auxiliary elastic element 722. The second sliding block 713 slides along the second guide rod 712 and is fixed in height by cooperating with the limiting plate through the limiting notch 724, which is suitable for drones of different sizes. The clamping frame 721 ensures stable clamping and achieves fully flexible contact to avoid damage to the surface of the drone, ensuring that the external structure does not shift during the final assembly process. By pressing down the pedal 83, the pedal 83 drives the support column 82 to slide downward, causing the first magnet 84 and the second magnet 86 to attract each other, and the second magnet 86 will slide into the support column 82, thereby achieving the effect of fixing the stopped loading platform in its original position. After the loading platform reaches the designated position, it can be manually locked to the preset fixed point on the ground, thus providing a stable foundation for subsequent assembly and debugging operations.

[0030] The second embodiment of the present invention provides a pulsed flow method for a heavy-duty flexible assembly platform for unmanned aerial vehicle (UAV) final assembly, specifically including the following steps: Step S1, Loading Positioning and Platform Locking: Step on pedal 83 to move support column 82 downward along support sleeve 81 closer to the ground, lift caster wheel off the ground and fix platform at work station reference position, lock caster wheel by attracting second magnet 86 with first magnet 84; hoist drone body above assembly platform, lower drone head into support frame 521, second support component 53 supports drone body, rotate second support plate 525 to move down along sliding notch 5213 to locking notch 5212, and rotate second support plate 525 to engage locking notch 5212, completing bottom support and front end clamping of drone body; Pulling the sliding rod 88 separates the second magnet 86 from the first magnet 84, and the third limiting elastic element 87 resets the support column 82, allowing the caster wheel to resume free rotation. S2, Assembly of mid-fuselage components: The AGV tows the assembly platform to the mid-fuselage assembly station and locks the casters. The installation and connection of the mid-fuselage power system, fuel lines, electrical cables and core avionics modules are completed in sequence, and the casters are restored to free rotation. During the assembly process, the first sliding block 532 slides down along the second support sleeve 531 and compresses the third support elastic element 534. The support height is adaptively adjusted according to the working load to ensure uniform force distribution in the mid-fuselage. S3, Front and rear end and external structure assembly: The AGV tows the assembly platform to the front and rear end assembly station and locks the casters; according to the fuselage size, the second sliding block 713 is pressed down and slides along the second guide rod 712 and compresses the first limiting elastic element 714, so that the second sliding block 713 moves to the corresponding height, and the limiting plate is inserted into the limiting notch 724 to fix the clamping frame 721 position, so that the external structures on both sides of the fuselage are inserted between the two sliding silicone baffles 723. The sliding silicone baffles 723 conform to the fuselage contour under the action of the auxiliary elastic element 722, and the installation and fastening of the nose avionics equipment, tail control surface, landing gear and wing pylons are completed in sequence; and the casters are restored to free rotation. S4, Overall debugging and precision testing: The AGV tows the assembly platform to the debugging and testing station and locks the casters; the power supply of the UAV is turned on, and the power system no-load test, control surface linkage debugging, avionics system function verification and communication link test are completed in sequence. The coaxiality, parallelism and assembly gap of the fuselage parts are detected by laser tracker, and the unqualified parts are adjusted and re-inspected on site. S5, Finished Product Offline and Platform Return: Rotate the second support plate 525 to the position of the sliding notch 5213. The second support plate 525 is reset under the action of the second support elastic element 526. Pull the sliding rod 88 to separate the second magnet 86 from the first magnet 84. The third limiting elastic element 87 resets the support column 82, and the universal wheel resumes free rotation. The drone that has completed final assembly and debugging is lifted off the assembly platform and transferred to the finished product area. The AGV pulls the assembly platform back to the loading station along the return channel. Clean the first protective shell 51 and debris on each support surface. Check the status of each elastic element and silicone contact element to prepare for the final assembly of the next drone.
