DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0034] The drawings will be described below in conjunction with the embodiments of the present application. Figure 1 to the drawings Figure 10 The present application will be described in detail below in conjunction with the drawings and specific embodiments.

[0035] As shown in Fig. Figures 1-10 The present application provides a production line for assembling unmanned aerial vehicles, which comprises two parallel main flow lines 1 and two parallel return flow lines 2, and the main flow lines 1 and the return flow lines 2 form a return-type production line.

[0036] ​Both the main line 1 and the return line 2 are equipped with conveying mechanisms (not shown in the figure). Each main line 1 has multiple assembly stations spaced apart along the conveying direction, and at least some of the assembly stations are equipped with carriers 3. The drones to be assembled are mounted on the carriers 3, and the carriers 3 are conveyed forward with the conveying mechanism. This application does not limit the length of the main line 1, as long as there are enough assembly stations on the main line 1 for the assembly of drones of various types and models. For example, each main line 1 has more than 10 assembly stations. When assembling a certain type of drone, all assembly stations can be used as needed, or only a few assembly stations can be used.

[0037] See Figure 9 , Figure 10 Each main line 1 has a transfer mechanism 4 at both ends. The transfer mechanism 4 is located below the conveyor mechanism of the return line 2, that is, the transfer mechanism 4 is located on the return line 2. It is used to transfer the carrier 3 on the main line 1 to the return line 2, so as to realize the circulation of the carrier 3 and the circulation of the drone. After the drone circulates once on the return line, it is assembled and the finished product is removed from the line and placed in the logistics pallet. The transfer mechanism 4 includes a lifting component 41 and a conveying component 42 located on the lifting end of the lifting component 41. The conveying direction of the conveying component 42 is perpendicular to the conveying direction of the return line 2. When the carrier 3 moves to the tail of the main line 1 and partially enters the return line 2, it contacts the conveying component 42. The conveying component 42 starts to move the carrier 3 forward until the carrier 3 is completely entered into the return line 2.

[0038] This invention utilizes a circular production line with multiple assembly stations. The carrier 3 circulates between these stations, and operators stand at their assigned stations while materials are placed beside them. Each operator is responsible for a specific assembly step, ensuring the orderly assembly of the drones. Once assembled, the finished product is removed from the line. Furthermore, this circular production line has a small footprint and is suitable for assembling various types of drones.

It can be understood that the shapes, sizes and structures of unmanned aerial vehicles with different functions are different, and the corresponding carrier 3 will also change, therefore, the specific structure of the carrier 3 is not limited in the application, and the carrier on the back-shaped production line can be replaced according to the requirement.

[0040] In some preferred embodiments, referring to Figure 4 The carrier 3 comprises a carrier bottom plate 31 and a carrier rotating plate 32 rotatably connected to the carrier bottom plate 31, and two long positioning blocks 33 are arranged in parallel on the carrier rotating plate 32, and a clamping groove 331 adapted to the bottom support column of the unmanned aerial vehicle is arranged on the long positioning block 33, and limiting blocks 34 in contact with the two ends of the bottom support column are arranged at the two ends of the clamping groove 331, the unmanned aerial vehicle is clamped on the carrier 3 through the bottom support column, and the unmanned aerial vehicle cannot move in the front-rear and left-right directions, and the unmanned aerial vehicle can rotate with the carrier rotating plate 32 to meet the angle position switching in the assembly process. It can be understood that the shapes, sizes and structures of unmanned aerial vehicles with different functions are different, and the corresponding carrier 3 will also change, therefore, the specific structure of the carrier 3 is not limited in the application, and the carrier on the back-shaped production line can be replaced according to the requirement.

[0041] It should be noted that the carrier 3 with the above two structures is used for fixing the unmanned aerial vehicle with the bottom support column, when the unmanned aerial vehicle with a different support structure is developed with the progress of science and technology, the carrier 3 only needs to be replaced, so that the back-shaped production line of the application can be assembled.

[0046] In some embodiments, a protective net 9 is arranged outside the conveying end of the return production line, and the blanking station, the blanking manipulator 7 and the detection manipulator 8 are all located in the protective net 9, so as to prevent personnel from approaching and causing safety problems.
