[0025] The lifting assembly includes a rectangular frame plate 12, which is fixedly mounted on the base 1. A screw rod 13 is rotatably connected between the upper and lower inner walls of the rectangular frame plate 12 through a bearing. A slider 14 is threadedly connected to the screw rod 13.

[0028] Use the air pump 18 to inflate the air tank 19, and refer to the barometer 28 to obtain the change in the internal air pressure of the air tank 19. When the pressure inside the air tank 19 is increased, the air can flow into the two air cylinders 21, thereby pushing the two clamping plates 25 closer to each other, thereby clamping the fin heat exchanger. Open the valve on the exhaust pipe 20, and the reset spring 31 can pull the clamping plate 25 to reset, so that the air in the air cylinder 21 and the excess air in the air tank 19 are discharged, and the fin heat exchanger can be lowered.

[0029] Working principle of this utility model:

[0030] The device is moved to a designated position by means of a plurality of universal casters 3. According to the light spots emitted by the plurality of laser pens 11, the drive motor 15 can be controlled to drive the screw rod 13 to rotate, so that the screw rod 13 drives the slider 14 to slide inside the rectangular frame plate 12 in a screw transmission manner, until the slider 14 pulls the clamping assembly to move to the same height as the fin heat exchanger to be processed, and then the operation of the drive motor 15 is stopped. The clamping assembly is pushed to move by means of the plurality of universal casters 3, so that the two clamping plates 25 are moved to both sides of the fin heat exchanger to be processed;

[0031] The air pump 18 is activated to inflate the inside of the air tank 19. As the air continues to enter, the air pressure inside the air tank 19 increases, and part of the air will enter the inside of the air cylinder 21 along the air pipe 22. The air pushes the piston 23 to move toward the position of the limit ring 27. The piston 23 pushes the clamping plate 25 to move with the help of the guide rod 24, so that the two clamping plates 25 are close to each other until the rubber block 26 is close to the fin heat exchanger to be processed and the fin heat exchanger to be processed is firmly clamped. The air pressure value inside the air tank 19 can be obtained by observing the barometer 28. When the air pressure value reaches the specified range, the operation of the air pump 18 is stopped. At this time, the air pressure inside the air tank 19 is significantly higher than the normal atmospheric pressure, and the clamping assembly firmly clamps the fin heat exchanger to be processed.

[0032] Afterwards, the driving motor 15 is controlled to pull the clamping assembly to move upward with the clamped fin heat exchanger, and the position of the fin heat exchanger is transferred with the help of multiple universal casters 3, so that the fin heat exchanger can be processed. When the fin heat exchanger needs to be flipped, the electric push rod 8 can be controlled to drive the rack 10 to move, and the rack 10 and the gear 6 are engaged with each other to drive the fin heat exchanger to complete the flipping operation.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
