At this time, the top-level temporary storage transfer assembly 6 connects with the inbound / outbound transfer assembly 7.

After the upper-level temporary storage transfer assembly 6 has received the chassis transferred by the inbound / outbound transfer assembly 7, the lifting motor 4-1-1 in the lifting drive assembly 4 starts, driving the two sets of... The lifting screws 4-3 rotate synchronously, thereby driving the temporary storage rack structure 5 to rise to a preset height, so that the temporary storage and transfer component 6 located on the next layer can connect with the inbound and outbound transfer component 7, thereby receiving the chassis transferred by the inbound and outbound transfer component 7 and moving the chassis to the depth of the temporary storage rack structure 5 for temporary storage; the above operation is repeated until each temporary storage and transfer component 6 has received and temporarily stored the chassis, and then the lifting motor 4-1-1 starts, driving the two sets of lifting screws 4-3 to rotate synchronously in opposite directions, and the temporary storage rack structure 5 descends to the initial position, making it convenient for the staff to push the transfer cart component 1 to transfer multiple chassis to other places for subsequent processing or storage;

[0034] After the staff pushes the transfer device of this utility model to the position to be processed or stored, the temporary storage and transfer component 6 at the top is activated, and the chassis on it is transferred in reverse to the inlet and outlet transfer component 7 that is connected to it. Then, the lifting cylinder 8-3 in the workpiece lifting component 8 is activated, and the chassis received by the inlet and outlet transfer component 7 is lifted to a suitable height, so that the staff or the robot arm configured in the workshop can grab the chassis for transfer; or the inlet and outlet transfer component 7 is activated, and the chassis on it is transferred in reverse to the output device that is connected to the inlet and outlet transfer component 7.
