[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an onboard computer. Its current applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, etc., have greatly expanded the uses of drones themselves.

[0003] In the field of civilian use of UAVs, UAVs can be divided into four types: fixed-wing UAVs, multi-rotor UAVs, unmanned helicopters and composite-wing UAVs. In the existing assembly of fixed-wing UAVs, the fuselage of the UAV is usually placed at a certain location in the factory, and then various assembly processes of the UAV are carried out in sequence. For example, the internal cockpit, cargo hold and tail cabin structure of the UAV, the belly antenna of the UAV, the top antenna of the UAV, the engine, the lubricating oil radiator of the UAV and other early installations of the UAV are first installed; then the mid-term installations such as the internal avionics wiring and socket connection of the fuselage are carried out; finally, the upper and lower wings, the vertical tail and the rudder are installed with the fuselage, the fairing skin is installed, the wing box strut is installed and the propeller is installed; different types of installation tools will be used in the early, middle and late installation processes.

[0036] like Figure 1-Figure 10 Shown

[0037] A large-scale unmanned aerial vehicle assembly device includes a fixed platform 1. The fixed platform 1 is laid on the ground of the installation plant, which can provide a stable and flat working environment during the assembly process of the unmanned aerial vehicle, solve the problem of uneven ground, and help ensure the accuracy of unmanned aerial vehicle assembly. The fixed platform 1 can also improve work safety, such as improving anti-slip and anti-fall performance, and reducing the risk of employees being injured during the assembly process. In addition, the platform can also help isolate direct contact between the production line and the ground, prevent safety hazards caused by poor ground conditions, and facilitate cleaning and maintenance, helping to keep the factory clean and hygienic; specifically, such as Figure 1 and Figure 2 As shown, the fixed platform 1 is constructed by a number of crisscross steel pipes. The longitudinal steel pipes and the transverse steel pipes can be fixedly connected by welding, bolting, etc., and a support column is fixedly connected at the intersection of each longitudinal steel pipe and the transverse steel pipe. The support column contacts the ground to provide support for the steel pipe. At the same time, one end of the support column in contact with the ground is a disc, which can increase the contact area with the ground and improve its stability. A number of steel plates are installed on the upper end surface of the steel pipe by welding, screws, etc., and the steel plates are evenly laid on the upper end surface of the steel pipe to ensure the overall flatness.

[0038] In the present invention, a mobile channel 2 is provided in the middle of the fixed platform 1, and is divided into a first work area 201, a second work area 202, and a third work area 203 from left to right along the length direction of the mobile channel 2. The mobile channel 2 is divided into three working areas, and the front, middle, and late installation and assembly are completed in the corresponding areas respectively. That is to say, when the UAV fuselage is assembled in the corresponding area, it can be moved to the next area for assembly through the mobile channel 2, and there is no need to clean the assembly tools in the previous assembly stage, which can greatly improve the assembly efficiency of the UAV. Among them, the first work area 201 is used by operators to implement the early installation and assembly of the UAV internal cockpit, cargo compartment and tail cabin structure installation, UAV belly antenna installation, UAV top antenna installation, engine installation, etc.; the second work area 202 is used for the mid-term installation and assembly of the UAV fuselage internal avionics wiring and socket connection; the third work area 203 is used for the upper and lower wings, the vertical tail and the rudder and the fuselage, the installation of the fairing skin, the installation of the wing box struts and the installation of the propeller, etc.

[0039] In the present invention, in order to facilitate the movement of the drone body in the moving channel 2, the moving channel 2 is provided with a slide rail 3 which connects the first work area 201, the second work area 202, and the third work area 203 in series, and a self-propelled component 4 is slidably connected to the slide rail 3. The self-propelled component 4 is used to place the drone body and provide driving force for the movement of the drone body on the moving channel 2. Specifically, Figure 1 , Figure 5 and Figure 6 As shown, the slide rail 3 includes a base fixedly mounted on the moving channel 2, the base is parallel to the length direction of the moving channel 2, the lower end surface of the base is fixedly connected to the ground, and the upper end surface of the base is installed with a long strip guide rod. The self-propelled component 4 includes a front landing gear support 401 and a rear landing gear support 402. The bottom of the front landing gear support 401 is slidably connected to the slide rail 3 through a guide mechanism 4011, specifically: the guide mechanism 4011 includes a guide frame 40111 and a guide wheel 40112, as shown in FIG. Figure 7 and Figure 8 As shown, the front landing gear support member 401 is a trapezoidal steel frame structure, rollers are installed on the bottom surfaces of the left and right sides of the front landing gear support member 401, the guide frame 40111 is fixedly installed on the middle bottom surface of the front landing gear support member 401, the guide wheel 40112 is rotatably installed on the guide frame 40111, and the cross-section of the guide wheel 40112 presents an "I" shape, and the left and right sides of the guide rod are arc-shaped convex edges, which are adapted to the "I"-shaped guide wheel 40112 and can limit the freedom of the guide frame 40111 in the up and down directions; in addition, the guide wheels 40112 are provided on the left and right sides of the guide frame 40111 and are respectively fitted with the left and right sides of the guide rod, so as to limit the freedom of the guide frame 40111 in the left and right directions, so that the guide frame 40111 can only move forward and backward along the length direction of the guide rod, thereby realizing its guiding effect on the movement of the front landing gear support member 401. The side surface of the front landing gear support member 401 is fixedly connected to the rear landing gear support member 402 via a connecting rod 403 . The rear landing gear support member 402 is powered and drives the front landing gear support member 401 to move via the connecting rod 403 .

[0040] In the present invention, the rear landing gear support 402 includes a driving trolley 4021 and a placement frame 4022 for placing the rear landing gear of the UAV. The driving trolley 4021 is placed above the slide rail 3. During assembly, the rear landing gear of the UAV fuselage is placed on the placement frame 4022, and the driving trolley 4021 drives the UAV fuselage to move.

[0041] During the assembly process of the drone, it is necessary to make slight adjustments to the angle of the drone body in some installation processes. For example, when installing the flight control system, the flight control system is the core part of the drone, and its installation position and angle have a crucial impact on the flight performance of the drone. After installing the flight control system, it may be necessary to adjust its relative angle with the fuselage to ensure the accuracy of its sensors and signals. Therefore, in order to achieve quick adjustment of the drone body angle, the rear landing gear support 402 and the jack can be used to achieve the adjustment of the drone body angle. Specifically, Fig. 9 and Fig.10 As shown, the upper end surface of the driving trolley 4021 is provided with a horizontal first mounting plate 4023 and a vertical second mounting plate 4024, wherein the second mounting plate 4024 is provided with a slider 7, and the side of the placement frame 4022 is provided with a guide rail 6, and the guide rail 6 is adapted and slidably connected to the slider 7; the upper end surface of the first mounting plate 4023 is provided with a guide rail 6, and is slidably connected to a third mounting plate 4025 through a slider 7 adapted to the guide rail 6, and the third mounting plate 4025 is a triangular plate, and its hypotenuse is adapted to the bottom surface of the placement frame 4022, and the hypotenuse is provided with a guide rail 6, and the bottom surface of the placement frame 4022 is provided with a slider and is slidably connected to the hypotenuse; the upper end surface of the driving trolley 4021 is installed with a telescopic cylinder 8, and the output end of the telescopic cylinder 8 is fixedly connected to the third mounting plate 4025. When the output end of the telescopic cylinder 8 extends forward, it pushes the third mounting plate 4025 to slide forward, and under the action of the hypotenuse of the third mounting plate 4025, the placement frame 4022 slides upward, thereby driving the rear end of the drone fuselage to move upward; conversely, when the output end of the telescopic cylinder 8 contracts backward, it drives the third mounting plate 4025 to slide backward, and under the action of the hypotenuse of the third mounting plate 4025, the placement frame 4022 slides downward, thereby driving the rear end of the drone fuselage to move downward; the fuselage angle is fine-tuned by slightly lifting and lowering the rear end of the drone fuselage.

[0042] like Fig.10 As shown, the placement frame 4022 includes a front arc block and a rear arc block, which cooperate with each other. When the wheels of the rear landing gear of the fuselage are placed in the placement frame 4022, the front arc block and the rear arc block fit with the arc surface of the wheel to play a supporting role. The side of the placement frame 4022 is threadedly connected with an adjusting screw, and the adjusting screw can be rotated to clamp the side of the landing gear wheel to ensure the stability of the rear landing gear wheel.

[0043] In the present invention, when the fuselage is located in the moving channel 2, since there is a certain height difference between the fixed platform 1 and the moving channel 2, it is not convenient for the operator to walk from the fixed platform 1 to the fuselage to perform assembly operations. Therefore, in order to facilitate the operator to move from the fixed platform 1 to the fuselage to complete the assembly, the fixed platform 1 corresponding to the first workstation area 201 and the second workstation area 202 is slidably connected with a working platform 5, and the working platform 5 can extend into the moving channel 2 when sliding. When the working platform 5 moves into the moving channel 2, the operator can easily walk to the fuselage through the working platform 5 to complete the assembly operation. Specifically, Figure 3 and Figure 4As shown, the specific structure of the working platform 5 is similar to that of the fixed platform 2, including a rectangular frame and a steel plate fixedly installed on the upper end surface of the rectangular frame, the lower end surface of the rectangular frame is installed with rollers, and the working platform 5 is located below the fixed platform 1; when the working platform 5 is needed, the working platform 5 is moved from the bottom of the fixed platform 1 to the moving channel 2 through the rollers and is close to the side of the drone body; when the working platform 5 is not needed, the working platform 5 is moved back to the bottom of the fixed platform 1 to avoid the working platform 5 blocking the moving channel 2; the sliding of the working platform 5 on both sides of the moving channel 2 can correspondingly control the opening and closing of the moving channels 5 on the first workstation area 201, the second workstation area 202, and the third workstation area 203; during assembly, the working platform 5 between adjacent workstation areas can be moved to the moving channel 2, and the workstation areas can be effectively separated by the blocking of the working platform 5 to avoid interference between different assembly tasks, so that the assembly work can be carried out more orderly and efficiently.

[0044] like Figure 3 As shown, an electric push rod 9 is installed below the fixed platform 1 corresponding to each working platform 5. The electric push rod 9 is fixedly installed on the end surface of the fixed platform 1. The conveying end of the electric push rod 9 is fixedly connected to the lower end surface of the working platform 5. The contraction of the electric push rod 9 provides power for the movement of the working platform 5. In order to ensure that the working platform 5 can move horizontally, a guide frame 10 is provided between every two adjacent working platforms 5. The cross section of the guide frame 10 is T-shaped, and its horizontal side is fixedly installed on the lower end surface of the fixed platform 1. Pulleys 11 are installed on the left and right sides of the vertical side. The left and right sides of the working platform 5 are provided with slide grooves 12 adapted to the pulleys 11. The cooperation between the pulleys 11 and the slide grooves 12 can not only provide a guiding effect for the movement of the working platform 5, but also reduce friction and improve the movement efficiency of the working platform 5.

[0045] In the present invention, the first work area 201, the second work area 202, and the third work area 203 can work simultaneously, that is, the assembly device can assemble three drones at the same time, greatly improving the assembly efficiency of the drones. When the assembly of the drones in the third work area 203 is completed, the self-propelled component 4 there will move out of the slide rail 3, and the self-propelled component 4 will move back to the first work area 201 and re-slidably connect with the slide rail 3.

[0046] The workflow of the present invention is:

[0047] The aircraft fuselage, wings, vertical tail and other complete parts are transported to the safety passage near the first workstation area 201 by a flatbed transporter, and the wings, vertical tail and other parts are unloaded by a crane and placed on the wing transport trailer and transferred to the fixed platform 1. The fuselage is hoisted to the first workstation area 201 by a hoisting device, such as a gantry crane above the factory building, so that the rear landing gear of the fuselage is located in the placement frame 4022 and the rear landing gear is fixed by adjusting the screw. At the same time, a movable jack is placed in the middle of the fuselage to support the middle of the fuselage. It should be noted that the height of the jack is greater than the height of the placement frame 4022 at this time, so that the fuselage is in an upward tilted state, and the front end of the fuselage is tilted upward, which is convenient for operators to assemble the front landing gear. After the fuselage is fixed, the aircraft structure is assembled (installation of the aircraft's internal cockpit, cargo hold and tail cabin structure, aircraft belly antenna installation, aircraft top antenna installation, installation of internal installation from the lower fairing of the engine, and related installation of the rear of the fuselage external door) and the lubricating oil radiator are installed. The front landing gear can be assembled in the first work area 201 or in the subsequent third work area 203; if it is installed in the first work area, since the fuselage is tilted forward and the height is high, it is necessary to increase the height of the fixed platform 1 at the first work area 201 (the platform height is 2 meters), or place a ladder in the moving channel to allow the operator to install it. However, since the moving channel 2 at the front end of the first work area 201 is adjacent to the second work area 202, the space is limited. It is preferred to install the front landing gear in the third work area 203. When installing in the third work area 203, there is no need to increase the height of the fixed platform 1, which can ensure the consistency of the first work area 201 and the second work area 202, saving costs. At the same time, the moving channel 2 at the front end of the third work area 203 has a wide space for placing a ladder.

[0048] After the assembly of the UAV in the first workstation area 201 is completed, the fuselage is moved to the second workstation area 202 by driving the trolley 4021 for avionics-related assembly (avionics wiring and socket connection inside the fuselage, etc.);

[0049] After the assembly of the drone in the second workstation area 202 is completed, the fuselage is moved to the third workstation area 203 by driving the trolley 4021 to align the upper and lower wings, the vertical tail and the rudder with the fuselage, and to install the fairing skin, the wing box struts and the propeller. The installation order of the upper and lower wings is to install the upper wing first and then the lower wing. In addition, when aligning and aligning the upper and lower wings, the vertical tail and the rudder with the fuselage, the components placed on the fixed platform 1 are first hoisted to the third workstation area 203 by the hoisting device, and the components are suspended at the corresponding position of the fuselage. At the same time, the tail hydraulic working platform and the upper and lower wing hydraulic working platforms are lifted to the corresponding heights to facilitate the operator to assemble the components.

[0050] After the drone is assembled in the third workstation area 203, the device is removed and the assembly is completed after horizontal measurement and weighing are performed and no problems are found.
