The welding line for transformer fin tubes according to claim 5, wherein the lifters on the crane are configured to facilitate a clearance snap-fit of comb-tooth sections between fins to smoothly transfer the fins from the tracked trolley into the work area; the comb tooth part is provided with a bottom sliding block, the bottom sliding block can be arranged on the lifting frames in a sliding mode along the Y-axis direction, and a space suitable for the length size of the radiating fins is defined between the comb tooth parts on the two lifting frames which are arranged at intervals correspondingly.
7. Welding line for transformer radiator tubes according to claim 1, wherein said support table is provided, in its working area, with a snap-in cavity for the placement of the oil collection tube and with a rotary member for radially confining the oil collection tube inside the snap-in cavity, said rotary member being rotationally oscillating in an electrically controlled manner between a first position and a second position, corresponding to the lateral snap-in on the oil collection tube after switching to the second position.
8. The welding production line for the transformer fin tube according to claim 7, further comprising a positioning mechanism for axially limiting the oil collecting tube in the clamping cavity; the positioning mechanism comprises a base arranged outside the support table and a butt joint component arranged on the base, and the butt joint component enables the base and the oil collecting pipe to be mutually jointed after being aligned to the oil collecting pipe.
9. The welding line for transformer fin tube according to claim 1, wherein the welding robot is movably disposed on the back of the support platform, the welding robot has at least two welding guns, and the welding guns are movably disposed on two adjacent ends of the welding robot via slide rails; and the welding workstation at least comprises all-round welding operations including horizontal welding, vertical welding and overhead welding.
10. The welding production line for the transformer fin tube according to claim 1, wherein the feeding unit, the first welding unit, the temporary storage unit, the second welding unit and the discharging unit are sequentially arranged along a production line direction defined by a transmission path, and the temporary storage unit is arranged between the first welding unit and the second welding unit and used for carrying out a waiting and placing access operation on a frequently-circulated radiator.
