[0044] The embodiments of the present application will be described in detail below with reference to the drawings.

[0047] It is also to be understood that the following description is only one example of the application, and that numerous changes in the details of construction and the combination and arrangement of parts can be made by those skilled in the art without departing from the scope of the application as set forth below or the scope of the claims.

[0048] In addition, in the following description, numerous specific details are provided for a thorough understanding of examples. One skilled in the relevant art will recognize, however, that the aspects described herein can be practiced without one or more of these specific details, or with other methods, components, materials, and so forth.

[0049] In semiconductor manufacturing, wafers are transported by an aerial transportation system, and the aerial transportation vehicle runs on a walking track and carries the wafer to the designated position according to the designated requirements. The existing aerial transportation vehicle walking track is a straight track and a curved track in an integrated structure, and the bending radius of the curved track is limited by the bending process, which affects the layout of the entire aerial transportation vehicle track system. The mechanical properties of the curved track processed by the bending process are poor, and the weight of the aerial transportation vehicle body is fully applied to the curved track when passing through the curve, which causes the curved track to be easily damaged and affects the stability of the aerial transportation vehicle. Therefore, the first curved track piece 5 is used to replace the existing curved track, and the first curved track piece 5 supports the aerial transportation vehicle when passing through the curve, which can reduce the wear of the aerial transportation vehicle when passing through the curve and ensure the stability of the aerial transportation vehicle when passing through the curve. At the same time, the first curved track piece 5 can be made of aluminum plate by machining, which is not affected by the bending process and is convenient for the layout of the aerial transportation vehicle track system.

[0050] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings Figures 1 to 9

[0051] As shown in Figure 1 , a walking track of an aerial transportation vehicle includes a plurality of straight track segments 1, a turnout segment arranged on one side of the straight track segment 1, and a guide track 6 arranged above the turnout segment. The straight track segment 1 includes two straight tracks arranged in parallel and used to support the aerial transportation vehicle to travel. The straight track segment 1 and the guide track 6 are suspended in the air. The turnout segment includes at least one first curved track piece 5 in the form of a plate. The first curved track piece 5 is arranged inside the traveling direction of the aerial transportation vehicle at the turnout. A first end of the first curved track piece 5 is connected to a first straight track, and a second end of the first curved track piece 5 is connected to a second straight track. The first end and the second end are opposite ends of the first curved track piece 5. The first curved track piece 5 is used to support the aerial transportation vehicle to travel at the turnout. By arranging the first curved track piece 5 in the form of a plate at the track turnout segment and supporting the aerial transportation vehicle when traveling at the turnout through the first curved track piece 5, the wear of the walking wheels, guide wheels, and curved wheels of the aerial transportation vehicle can be reduced, the dust generated by the wear of the aerial transportation vehicle can be reduced, the stability of the aerial transportation vehicle when passing through the curve can be ensured, and the influence of the vibration on the wafer transported by the aerial transportation vehicle can be avoided. The first curved track is in the form of a plate, so the first curved track piece 5 is not affected by the bending process and is not affected by the machining radius. The machining precision is higher, and the layout of the aerial transportation vehicle track system is facilitated. At the same time, the first curved track piece 5 has better mechanical properties than the curved track produced by the bending process, which ensures the supporting effect on the aerial transportation vehicle.

[0052] ​In some embodiments, the aerial transport vehicle walking track further comprises a guide guide 7, wherein the guide guide 7 is arranged at the end of the guide rail 6 in the direction of the aerial transport vehicle, and the guide guide 7 is arranged obliquely from the intersection of the guide guide 7 and the guide rail 6 to the other end of the guide guide 7 away from the straight rail connected with the first curved rail 5. When the guide wheels of the aerial transport vehicle travel to the end of the guide rail 6, the guide wheels of the aerial transport vehicle continue to travel along the guide guide 7, so that the suspended traveling wheels of the aerial transport vehicle in the turnout transition back to the traveling rail. By adding the guide guide 7 at the end of the guide rail 6, the guide guide 7 can guide the guide wheels of the aerial transport vehicle when turning, ensure that the aerial transport vehicle enters the correct track, and avoid the phenomenon that the transport vehicle tilts or falls off the track, thereby ensuring the normal operation of the walking track.

[0053] In some embodiments, the aerial transport vehicle walking track further comprises a first hoisting piece 4, and the upper surface of the first curved rail 5 is provided with a mounting portion of the first hoisting piece 4, so as to hoist the first curved rail 5 in the air through the first hoisting piece 4.

[0054] It should be noted that since the existing track is generally processed by completing the radius of the curved rail, it is generally difficult to add a hoisting piece 4 to the curved rail for hoisting. When the aerial transport vehicle turns, the weight of the aerial transport vehicle acts on the curved rail. Since the mechanical properties of the curved rail after bending are poor, the curved rail is prone to deformation, which leads to poor stability of the aerial transport vehicle when turning and is prone to jolting, thereby affecting the quality of the wafer.

[0061] like Figure 5 As shown, in some embodiments, the air transport vehicle's track also includes several first high-frequency cable brackets 2 for installing high-frequency cables. Each first high-frequency cable bracket 2 includes a first mounting foot, a second mounting foot, and a hook for fixing the high-frequency cable. By adding several first high-frequency cable brackets 2, high-frequency cables can be installed to ensure the normal operation of the air transport vehicle.

[0068] In some implementations, the air transport vehicle's track also includes a bend support 8;
