[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) First, move the electronic fan harness to be welded and engage the outer wall of the electronic component on the electronic fan harness with the inner wall of the first limiting groove. Then, engage the outer wall of the cable on the electronic fan harness with the inner wall of the second limiting groove. Then, the servo motor drives the rotating shaft to rotate, thereby driving the bearing plate to rotate. Then, with the cooperation of the auxiliary support wheel rotating along the inner wall of the auxiliary support column, the electronic fan harness to be welded can be transferred to the position directly below the pressing component and the welding component.

Then, the second pneumatic telescopic rod is driven to extend and slide by the operation of the second electric cylinder, thereby driving the top plate to move linearly upward, so that the top rod can be attached to the outer wall of the bottom surface of the corresponding electronic fan wire harness to be welded. At the same time, the limiting rod can slide linearly upward along the limiting hole and under the connecting action of the connecting rod, This allows the top rod to move stably and linearly. Then, the third electric cylinder drives the third pneumatic telescopic rod to extend and slide, which in turn drives the slider to slide linearly along the slide rail. This allows the welding rod on the outer wall of the bottom of the welding machine to contact the connecting wire of the electronic fan harness to be welded. Then, through the operation of the welding machine, the welding rod can weld the connecting wire of the electronic fan harness to be welded and the terminal block. This effectively realizes the function of rapid welding of electronic fan harnesses. Moreover, the electronic fan harness can be stably pressed during the welding process, avoiding accidental displacement and damage to the electronic fan harness during the welding process.

[0016] (3) By uniformly setting multiple clamping components, welding components and top support components on the upper surface of the support plate, and with the cooperation of the servo motor, the multiple sets of connecting wires of the electronic fan wire harness to be welded can be welded to the terminal block in sequence. This effectively realizes that the device has the function of completing the welding of the entire electronic fan wire harness in a single rotation process of the bearing plate through the multiple clamping components, welding components and top support components.
