Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0022] Embodiment 1: As Figures 1 - 4As shown in the figure, the present utility model provides a modular EMS air conveying system, including: an air slide rail 1, a modular power vehicle 2 is arranged on the outer surface of the air slide rail 1, a fixed frame 3 is fixedly connected to the bottom of the modular power vehicle 2, an electric telescopic rod 4 is fixedly connected to the inner bottom of the fixed frame 3, the telescopic end of the electric telescopic rod 4 slidably penetrates the outer surface of the fixed frame 3, the telescopic end of the electric telescopic rod 4 is fixedly connected to a mounting frame 5, a bottom plate 6 is fixedly connected to the bottom of the mounting frame 5, and a mounting plate 7 is fixedly connected to the top of the bottom plate 6; an adsorption assembly 9, the adsorption assembly 9 is provided in multiple groups, and the multiple groups of adsorption assemblies 9 are symmetrically arranged on the outer surfaces of both sides of the mounting plate 7 respectively.

A limiting block 906 is fixedly connected to the end face of the rotating frame 902, the outer surface of the limiting block 906 is rotatably connected to the inner surface of the fixed block 901. The mounting plate 7 is located at the middle position of the top of the bottom plate 6, and the mounting plate 7 is parallel to the mounting frame 5.
[0023] The effect achieved by the entire Embodiment 1 is that when the modular EMS aerial conveying system is in use, after the modular power vehicle 2 slides along the aerial slide rail 1 to the loading location, the electric telescopic rod 4 is started. The telescopic end of the electric telescopic rod 4 extends outwards, driving the mounting bracket 5 to descend.

[0026] Working principle: When the modular EMS air conveying system is in use, after the modular power vehicle 2 slides along the air slide rail 1 to the feeding location, the electric telescopic rod 4 is started. The telescopic end of the electric telescopic rod 4 extends outwards, driving the mounting bracket 5 to descend. After the bottom plate 6 touches the ground, according to the adsorption position of the car door component, the positions of the two suction cups 905 are adjusted in sequence. Manually rotate the rotating frame 902, and it is rotationally limited in the fixed block 901 through the limit block 906, so that the disc 904 can rotate in multiple directions on the outer surface of the rotating frame 902 through the two connecting blocks 903, enabling the suction cup 905 to be perpendicular to the adsorption surface of the car door, and further enabling the suction cup 905 to adapt to the curved surface of the car door component. After the adsorption directions of the two suction cups 905 are adjusted, the assembled car door component to be transported is placed on the top of the bottom plate 6, and its arc surface abuts against the two suction cups 905 on the same side of the mounting plate 7. Start the vacuum generator 801. When the vacuum generator 801 is working, it evacuates the gas in the suction cup 905 through the connecting disc 802 and the pipe body 803, generating negative pressure inside it. The car door component abutting against its surface is fixed to one side of the mounting plate 7 under the adsorption action of the two suction cups 905 on the same side.
