After the straight tube is cleaned, the electric sliding block 3 is utilized to transversely move on the guide rail 2 again to drive the connecting block 23 to transversely move, then the concave electromagnet 24 can be driven to transversely move, the concave electromagnet 24 can be utilized to drive the steel-aluminum composite fin which is fixedly adsorbed to transversely move, the position of the steel-aluminum composite fin sleeved on the straight tube can be randomly adjusted, and the positions of a plurality of steel-aluminum composite fins on the straight tube can be adjusted according to actual needs.
After the positions of a plurality of steel-aluminum composite fins on the straight tube are adjusted, the first electric telescopic rod 21 is started, the piston rod of the first electric telescopic rod 21 retracts to drive the bearing plate 22 to move downwards, the bearing plate 22 can drive the connecting block 23 and the concave electromagnet 24 to move downwards until the concave electromagnet 24 is separated from contact with the steel-aluminum composite fins, the concave electromagnet 24 can still generate a suction force on the steel-aluminum composite fins after being separated from contact with the steel-aluminum composite fins, a downward force is further provided for the steel-aluminum composite fins, the steel-aluminum composite fins are blocked by the straight tube, the steel-aluminum composite fins can be further fixed on the straight tube, the steel-aluminum composite fins can be fixed on the straight tube under the condition that any part is not in contact with the steel-aluminum composite fins, the steel-aluminum composite fins can be fixed on the straight tube without any part, the part is prevented from being generated during the later welding of the steel-aluminum composite fins on the straight tube, the steel-aluminum composite fins can be further welded on the straight tube without any part, and the welding quality of the steel-aluminum composite fins on the straight tube can be further improved when the steel-aluminum composite fins are welded on the straight tube, and the steel-aluminum composite fins can be welded on the straight tube in a continuous welding mode.
After the steel-aluminum composite fins are welded on the straight pipes, the first electric telescopic rod 21 is started again, the piston rod of the first electric telescopic rod 21 pushes the connecting block 23 and the concave electromagnet 24 to move upwards, the concave electromagnet 24 is used for adsorbing the steel-aluminum composite fins again, at the moment, the electric sliding block 3 is started again, the electric sliding block 3 transversely moves on the guide rail 2 to drive the connecting block 23 and the concave electromagnet 24 to transversely move, the steel-aluminum composite fins are welded on the straight pipes, and when the concave electromagnet 24 transversely moves, a transverse force is provided for the steel-aluminum composite fins welded on the straight pipes, so that whether the steel-aluminum composite fins are welded on the straight pipes is firm or not can be detected, the quality of welding the steel-aluminum composite fins on the straight pipes can be detected, and the phenomenon that the welding quality of the steel-aluminum composite fins and the straight pipes is influenced due to the fact that the welding of some steel-aluminum composite fins on the straight pipes is not firm is avoided.
After the quality of the steel-aluminum composite fin welded on the straight pipe is detected, the concave electromagnet 24 is utilized to adsorb and fix the steel-aluminum composite fin welded on the straight pipe, two second electric telescopic rods 28 are started, the second electric telescopic rods 28 drive a first clamping plate 29 to move upwards to loosen the clamping and fixing of the outer wall of the end part of the straight pipe, a first motor 7 is started, an output shaft of the first motor 7 drives a positive and negative tooth bidirectional screw rod 8 to rotate so that two internal thread blocks 9 do mutual distance movement, further the two strip-shaped plates 26 do mutual distance movement to loosen the clamping and fixing of the straight pipe, the loosened straight pipe is fixed on a plurality of concave electromagnets 24 by utilizing the concave electromagnet 24 and the adsorption of the steel-aluminum composite fin welded on the straight pipe, the straight pipe welded with the steel-aluminum composite fin is transversely moved to the side of a collecting box 15 by utilizing the transverse movement of an electric sliding block 3 on a guide rail 2, the second motor 18 is started again to enable the rotating shaft 19 to drive the connecting block 23 and the concave electromagnet 24 to rotate, the concave electromagnet 24 further drives the straight pipe welded with the steel-aluminum composite fins to rotate to the upper portion of the collecting box 15, the concave electromagnet 24 is closed, the straight pipe welded with the steel-aluminum composite fins can be fed into the collecting box 15, automatic feeding of the straight pipe welded with the steel-aluminum composite fins can be automatically completed, the steel-aluminum composite fins can be fed onto the straight pipe in a sleeved mode, the position of the steel-aluminum composite fins on the straight pipe can be automatically adjusted, the straight pipe welded with the steel-aluminum composite fins can be automatically fed, the automation degree of the device in use is improved, human resources are saved, and the welding efficiency of the steel-aluminum composite fins and the straight pipe is improved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
