As shown in fig. 1 and fig. 2, a transfer device 100 for a vehicle-mounted skid according to an embodiment of the present invention includes a first mobile carrier 10, a second mobile carrier 20, and a jacking mechanism 30.

One of the first mobile carrier 10 and the second mobile carrier 20 is loaded with a vehicle carrying skid 200, a transfer position is set, and the first mobile carrier 10 and the second mobile carrier 20 can alternately move to the transfer position along a first direction; the two opposite sides of the switching position in the first direction are provided with jacking mechanisms 30, each jacking mechanism 30 comprises a tray 31, and each tray 31 is lifted between the first position and the second position; the tray 31 is located below the vehicle carrying skids 200 when in the first position, and the tray 31 can lift the vehicle carrying skids 200 to be separated from the first mobile carrier 10 or the second mobile carrier 20 when in the second position.

In the process of conveying the vehicle body, the vehicle carrying skid 200 is loaded on the first mobile carrier 10, the first direction is the left-right direction, for example, the first mobile carrier 10 moves rightwards to the transfer position, at this time, the tray 31 of the jacking mechanism 30 is just under the vehicle carrying skid 200, then the tray 31 rises from the first position to the second position, the vehicle carrying skid 200 is lifted from the first mobile carrier 10, then the first mobile carrier 10 moves leftwards quickly, the second mobile carrier 20 moves leftwards quickly to the transfer position, the tray 31 descends from the second position to the first position, the vehicle carrying skid 200 is placed on the second mobile carrier 20, then the second mobile carrier 20 moves rightwards quickly, and the vehicle carrying skid 200 can be transferred to other stations. Similarly, the second wheel transfer is performed, the first mobile carrier 10 conveys another vehicle-carrying skid 200 from left to right again, and then the second mobile carrier 20 transfers the other vehicle-carrying skid 200, so that the switching of fast carrying of articles between the two mobile carriers is realized fast.

It should be noted that, of course, the vehicle carrying skids 200 may be loaded first and the second mobile carrier 20 may be loaded first, and as described above, the first mobile carrier 10 transports the vehicle carrying skids 200 to the left. The first mobile carrier 10 and the second mobile carrier 20 can be electrically operated as a mobile machine, and the detailed structure and function thereof can be referred to in the prior art and are not described herein again.
