[0034] Specifically, the screwing device 300 can adopt an electric screwdriver, the bit is driven to rotate by a reduction motor, and the bit can screw the screw, so as to connect the airborne devices 2 such as the battery compartment and the pod to the fixing plate 1. During assembly, the first end of the flip fixture 200 can be placed below first, then the airborne devices 2 such as the battery compartment and the pod are placed at specific positions on the fixing plate 1, and then the pressing plate 400 is installed above the airborne device 2, so as to press the airborne device 2 between the fixing plate 1 and the pressing plate 400. Then, the flip fixture 200 flips and swaps the first end and the second end through the flip driving member 210, so that the fixing plate 1 can be located above. The relative positions of the flip fixture 200 and the screwing device 300 are adjusted by the sliding device 100 until the screwing device 300 is located above the fixing plate 1, and then the sliding device 100 is used to drive the screwing device 300 to move downward relative to the flip fixture 200, so that the screwing device 300 can tighten the screws on the fixing plate 1 one by one to realize the fixation of the airborne device 2.

[0035] In the embodiment of the present utility model, the flip fixture 200 includes: a base frame 220 and a flip frame 230 rotatably connected to the base frame 220; the flip frame 230 has a first end and a second end, the flip driving member 210 is installed on the base frame 220, and the flip driving member 210 is in transmission connection with the flip frame 230.

[0036] Specifically, the flip frame 230 is rotatably connected to the base frame 220 around an axis parallel to the y direction. The flip driving member 210 can adopt a stepping motor as the power source, and the power is transmitted by gear transmission or belt transmission to drive the flip frame 230 to flip relative to the base frame 220.
