The pipe conveying unit 21 is used for conveying the pipe 5 into the pipe positioning unit 22; the tube positioning unit 22 is used for positioning each tube 5 at a position opposite to each fin 4 so that the fin 4 is smoothly inserted into the tube 5.
The fin pushing unit 12 includes a plurality of fin guides 122 circumferentially arranged and rotatable, the tube positioning unit 22 includes a plurality of tube guides 222 circumferentially arranged and rotatable, each fin guide 122 extends axially with the tube guide 222, and the fin guides 122 rotate in synchronization with the tube guide 222, each fin guide 122 communicates with one tube guide 222 such that the fins 4 on the fin guides 122 are movable and inserted into the tubes 5 on the tube guide 222. Preferably, a pair of fin guide rails 122 and tube guide rails 222, which are in communication with each other, are connected to ensure synchronous rotation of the two.
The fin conveying units 11 are arranged on one side of each fin guide rail 122, and the pipe conveying units 21 are arranged on one side of each pipe guide rail 222, so that when each fin guide rail 122 rotates, the fin conveying units 11 are sequentially opposite to the fin conveying units 11, and the fin conveying units 11 sequentially feed fins 4 into each fin guide rail 122; when each pipe guide 222 rotates, the pipe guide rails are sequentially opposite to the pipe conveying units 21, so that the pipe conveying units 21 sequentially feed the pipes 5 into each pipe guide rail 222.
It should be noted that the fin conveying unit 11 and the tube conveying unit 21 simultaneously convey the fins 4 and the tubes 5 to the fin guide rail 122 and the tube guide rail 222 which are mutually communicated, so as to ensure that the pair of fin guide rails 122 and the tube guide rail 222 which are mutually communicated carry the fins 4 or the tubes 5 after rotating away from the fin conveying unit 11 and the tube conveying unit 21.

One end of each driving slider 123 extends into the slider pushing rail 126, so that when the fin guide rail 122 rotates circumferentially, the driving slider 123 moves along the fin guide rail 122 in a direction approaching the pipe guide rail 222 under the limit of the slider pushing rail 126, and then moves along the fin guide rail 122 in a direction separating from the pipe guide rail 222.
It should be noted that, when the fin 4 enters one of the fin guide rails 122 under the action of the fin conveying unit 11, the driving slider 123 in that fin guide rail 122 just moves to one end of the fin guide rail 122 far away from the pipe guide rail 222, so that the fin 4 can enter between the driving slider 123 and the pipe guide rail 222; when the fin guide rail 122 continues to rotate, the driving slide block 123 moves towards the direction approaching to the pipe guide rail 222, namely, the driving slide block 123 pushes the fin 4 to move towards the pipe guide rail 222, so that the fin is inserted into the opposite pipe 5; when the driving slide block 123 moves to the position closest to the pipe guide rail 222, the fin 4 is just completely inserted into the pipe 5; the fin guide rail 122 then continues to rotate, the driving slider 123 moves reversely under the limit of the slider pushing rail 126, and when the fin guide rail 122 moves to the fin conveying unit 11 again, the driving slider 123 moves to the end of the fin guide rail 122 far from the tube guide rail 222 again, and the above-mentioned actions are repeated.
