[0025] Reference Figures 1-4 As shown in the drawings, one embodiment of the present application is:

[0026] A working platform for unmanned aerial vehicle assembly, comprising a fixed platform 1, a moving channel 2 is formed in the middle of the fixed platform 1, specifically, the fixed platform 1 comprises a plurality of mutually connected main body frames 101, in this embodiment, the main body frame 101 is a rectangular frame, two adjacent main body frames 101 can be fixedly connected by screws or welding, preferably using screw connection, which facilitates disassembly of the main body frame 101 and facilitates later maintenance or replacement of the main body frame 101 in a certain area or region.

[0027] The upper end surface of each main body frame 101 is provided with a cover plate 4, which facilitates the walking of assembly personnel on the fixed platform 1; the lower end surface of the main body frame 101 is provided with a support column 102, which is arranged at the edge and corner of the main body frame 102 and plays a whole supporting role. In addition, the end of the support column 102 in contact with the ground is in a disc structure, which can increase the contact area with the ground and improve the stability of the fixed platform 1. The fixed platform 1 can provide a stable and flat working environment during the assembly of the unmanned aerial vehicle, solving the problem of uneven ground. In addition, the fixed platform can also help to isolate the direct contact between the production line and the ground, prevent safety hazards caused by poor ground conditions, and also facilitate cleaning and maintenance, which helps to keep the factory clean and sanitary.

[0028] As Figure 1As shown, along the length direction of the moving channel 2, from left to right, it is sequentially divided into the first work area 201, the second work area 202 and the third work area 203, wherein the first work area 201 is used for the operator to implement the installation and assembly of the unmanned aerial vehicle internal cockpit, cargo compartment and tail compartment structure, unmanned aerial vehicle belly antenna, unmanned aerial vehicle top antenna, engine and other early-stage installation and assembly; the second work area 202 is used for the installation and assembly of the unmanned aerial vehicle fuselage internal avionics wiring and socket connection and other middle-stage installation and assembly; the third work area 203 is used for the installation and assembly of the upper and lower wings, the vertical tail and rudder and the fuselage, the fairing skin, the wing box strut and the propeller and other late-stage installation and assembly. The assembly work of the unmanned aerial vehicle is carried out in the first work area 201, the second work area 202 and the third work area 203 respectively, and the corresponding assembly tools are placed in the corresponding work area. After the assembly of the previous work area is completed, the unmanned aerial vehicle only needs to be moved to the next work area for assembly, which greatly reduces the time for replacing the assembly tools, and the three work areas can also work simultaneously, carrying out the assembly of three unmanned aerial vehicles at the same time, thereby improving the assembly efficiency of the unmanned aerial vehicle.

[0029] When the unmanned aerial vehicle is assembled in the first work area 201 and the second work area 202, the assembly personnel need to walk from the fixed table 1 into the fuselage of the unmanned aerial vehicle. Since the moving channel 2 has a certain width, the lower end surface of each main body frame 101 located in the first work area 201, the second work area 202 and adjacent to the moving channel 2 is slidably connected with the telescopic table 3 through the guide piece 6. The telescopic table 3 is located below the main body frame 101. When the telescopic table 3 slides outward, the telescopic table 3 can extend into the moving channel 2, and the assembly personnel can walk into the fuselage through the telescopic table 3 to carry out assembly work. After the assembly is completed, the telescopic table 3 moves inward and moves out of the moving channel 2, so that the fuselage can move to the next assembly area in the moving channel 2.

[0030] Specifically, the telescopic table 3 includes a moving frame 301, the overall structure and shape of the moving frame 301 are the same as those of the main body frame 101 and slightly smaller than those of the main body frame 101, the guide piece 6 includes a mounting frame 601 and a guide wheel 602, the mounting frame 601 is mounted on the left and right sides of the lower end surface of the main body frame 101, the guide wheel 602 is rotatably mounted on the side surface of the mounting frame 601, and the left and right sides of the moving frame 301 are provided with guide grooves 302 which are slidably matched with the guide piece 6, specifically, Figure 4As shown, the cross section of the guide groove 302 is "C" shaped, the guide wheels 602 are transversely located in the gap of the C-shaped guide groove 302 and fit the inner wall of the guide groove 302. Through the cooperation of the guide wheels 602 and the guide groove 302, the freedom of the moving frame 301 in the up-down direction can be restricted, and through the cooperation of the two guide wheels 602 and the guide groove 302, the freedom of the moving frame 301 in the left-right direction can be restricted, so that the moving frame 301 can only move forward and backward into or out of the moving channel 2. In addition, during the forward and backward movement of the moving frame 301, the guide wheels 602 can also rotate together, reducing the friction between them and the moving frame 301 through rolling friction.

[0031] As shown in Figure 2 and Figure 4 As shown in the first work area 201 and the second work area 202, an installation frame 601 can be shared between adjacent main frames 101, improving the compactness of the device and saving costs. The guide wheels 602 are rotatably installed on the left and right sides of the installation frame 601, which are used to cooperate with two different moving frames 301.

[0032] The upper end surface of the moving frame 301 is provided with a cover plate 4, and the lower end surface is provided with a support wheel 303, which is used for the movement and support of the moving frame 301.

[0033] In order to realize the automatic sliding of the telescopic platform 3, a telescopic cylinder 7 is installed at the lower end surface of each main frame 101 located in the first work area 201, the second work area 202 and adjacent to the moving channel 2, and the output shaft of the telescopic cylinder 7 is connected to the lower end surface of the corresponding moving frame 301. The telescopic cylinder 7 not only connects the main frame 101 and the moving frame 301, but also realizes the sliding of the telescopic platform 3 through the extension and contraction of the telescopic cylinder 7. When the output shaft of the telescopic cylinder 7 extends outward, the telescopic platform 3 slides outward into the moving channel 2. When the output shaft of the telescopic cylinder 7 retracts inward, the telescopic platform 3 slides inward and moves out of the moving channel 2.

[0034] When the telescopic platform 3 slides outward, in order to avoid the moving frame 301 from touching and damaging the fuselage, the end of the moving frame 301 facing the conveying channel 2 is provided with a flexible strip 8, which can be made of flexible materials such as sponge and rubber, and is fixedly connected to the moving frame 301 by adhesive. The use of adhesive also facilitates the replacement of the flexible strip 8.

[0035] Due to the height difference between the moving frame 301 and the main frame 101, there is a gap between the cover plate 4 on the moving frame 301 and the lower end surface of the main frame 101. When the telescopic table 3 slides back and forth, impurities remaining on the cover plate 4 after assembly, such as bolts, gaskets and other small assembly parts accidentally left on the cover plate 1 by the assembly personnel, or other impurities carried by themselves, will be stuck in the gap between the cover plate 4 and the lower end surface of the main frame 101, affecting the normal sliding of the moving frame 301, and even causing damage to the telescopic table 3 and the fixed table 1. Therefore, each main frame 101 located in the first work area 201, the second work area 202 and adjacent to the moving channel 2 is provided with a stop block 5 at the end close to the moving channel 2, as shown in Figure 2 and Figure 3 The cross section of the stop block 5 is a right triangle, one of the right angles is fixedly connected with the main frame 1, the other right angle is closely attached to the upper end surface of the cover plate 4 on the moving frame 301, and the inclination angle A between the inclined side and the upper end surface of the cover plate 4 is 15°-30°. When the telescopic table 3 slides, the inclination angle of 15°-30° facilitates the movement of impurities to the inclined side of the stop block 5, avoiding the impurities being stuck in the gap between the cover plate 4 and the main frame 101, and ensuring the normal sliding of the telescopic table 3.

[0036] The working process of the utility model is as follows:

[0037] The whole machine parts such as the fuselage, wings, vertical tail and the like are transported close to the safety channel of the first work area 201 by the flatbed transport vehicle, the wings, vertical tail and the like are unloaded by the crane and placed on the wing transport trailer and transported to the fixed table 1, the fuselage is hoisted to the first work area 201 by the hoisting device such as the gantry crane above the factory building, and placed on the existing transport vehicle in the moving channel 2, and the aircraft structure assembly (aircraft internal cockpit, cargo compartment and tail compartment structure installation, aircraft belly antenna installation, aircraft top antenna installation, installation from the lower part of the engine fairing to the inside, related installation of the rear part of the fuselage external hatch), and the oil cooler installation are carried out;

[0038] After the unmanned aerial vehicle is assembled in the first work area 201, the fuselage is moved to the second work area 202 for avionics related assembly (fuselage internal avionics wiring and socket connection, etc.);

[0039] After the drone is assembled in the second workstation 202, the fuselage is moved to the third workstation 203 for the alignment of the upper and lower wings, the vertical stabilizer, and the rudder with the fuselage. The installation of the fairing skin, the wing box struts, and the propellers is then completed. The order of installation is to first install the upper wing and then the lower wing. Furthermore, when aligning the upper and lower wings, the vertical stabilizer, and the rudder with the fuselage, the components placed on the fixed platform 1 are first hoisted to the third workstation 203 using a hoisting device and suspended at corresponding locations on the fuselage. Simultaneously, the third workstation 203 is also equipped with a hydraulic work platform for the tail and upper and lower wings. These hydraulic work platforms can be raised and lowered, facilitating assembly of the tail and wings by the assemblers.
