[0055] Working principle: when using the device to assemble the fan casing, first remove and disassemble 10, plug the assembly structure of the fan casing body 5 into 10 in sequence, then dock the assembly structure joints of the fan casing body 5, and then install 10, so that the fan casing body 5 can be pressed according to the assembled shape, and then it can be transported to the conveying rack mechanism 6, and the conveying rack mechanism 6 is used to push the fan casing body 5 into the frame mechanism 3. After the structures of the fan casing body 5 protruding from both ends of 10 are plugged into 4, pull the structure at the bottom of the conveying rack mechanism 6 to pull the conveying rack mechanism 6. After exiting the frame mechanism 3, the structure of the inner wall of 4 is swung to lock 10, and then the edge pressing mechanism 13 is used to clamp the position of the fan casing body 5 so that the flipping angle of the fan casing body 5 and 4 are consistent. After controlling the edge pressing mechanism 13 to press on the outer edge of 4, the main control is started to make the main motor 9 and the auxiliary motor 8 run at the same time. The main motor 9 drives 4 and the fan casing body 5 to flip, and the auxiliary motor 8 continues to roll in place along the outer edge of 4 to press the seam of the outer edge of the fan casing body 5. After the processing is completed, the fan casing body 5 can be removed according to the above reverse steps.
