The transition conveying line 4 is installed between the drying conveying line 2 and the welding conveying line (not shown in the figure) in the production process of the heat exchanger 1. The transmission direction of the transition conveying line 4 is downward, and the rear end of the transition conveying line 4 is connected to the welding conveying line to realize the transition conveying production of the heat exchanger 1 drying down line and welding up line. The drying conveying line 2 is arranged straight, that is, arranged horizontally. The flip mechanism 3 is relatively arranged behind the drying conveying line 2 and connected with the front end of the transition conveying line 4. After the heat exchanger 1 is transferred from the drying conveying line 2 to the flip mechanism 3, it is rotated and flipped to the transition conveying line 4 via the flip mechanism 3.

[0026] The flipping mechanism 3 includes a fixed bracket 31, a rotating clamp, and a control motor 33. The fixed bracket 31 is relatively arranged on the rear side of the drying conveyor line 2 and is used to fix the rotating clamp. The height of the rotating clamp is greater than the height of the drying conveyor line 2, which is convenient for flipping the heat exchanger 1 and smoothly conveying it to the transition conveyor line 4. Accordingly, a rotating space is left between the rotating clamp and the rear side of the drying conveyor line 2, which is convenient for flipping the rotating clamp without interfering with the drying conveyor line 2. The rotating clamp is connected to the control motor 33, and the rotating clamp is controlled by the control motor 33 to realize the rotation action.

[0027] The rotating fixture is provided with a rotating shaft 32, a fixed clamp plate 323, a clamp tooth 322 and a belt line 321, one end of the fixed clamp plate 323 is connected to the rotating shaft 32, and the other end of the fixed clamp plate 323 is connected to a mounting plate 324, the rotating shaft 32 is connected to the control motor 33, the belt line 321 is fixedly connected to the mounting plate 324, the clamp tooth 322 is vertically arranged along the conveying direction of the belt line 321, and the clamp tooth 322 is arranged on both sides of the belt line 321, and the clamp tooth 322 on both sides of the belt line 321 will limit and fix the heat exchanger 1 flipped over from the drying conveyor line 2.

[0028] Preferably, there are four fixed splints 323 , and two of the fixed splints 323 are perpendicular to each other, one end of the four fixed splints 323 are fixedly mounted on the rotating shaft 32 , and the other end of the four fixed splints 323 are provided with a mounting plate 324 , and the belt line 321 is fixedly connected to adjacent mounting plates 324 , respectively.

[0032] The heat exchanger 1 is transported to the rear end of the drying conveyor line 2, and the control motor 33 controls the rotating fixture to rotate upward 90°. After flipping 90°, the belt line 321 starts to transport the heat exchanger 1 to the transition conveyor line 4, and finally to the welding conveyor line.

[0033] Keep the speed of the belt line 321 greater than the speed of the roller 22 on the drying conveyor line 2. After the rotating fixture flips the heat exchanger 1, the roller 22 of the drying conveyor line 2 continues to transport the next heat exchanger 1, avoiding interference between the fixture tooth 322 and the drying conveyor line 2, thereby improving the production efficiency of the "drying and welding" production line of the heat exchanger 1.

[0034] Preferably, a retaining frame 42 and a cross frame 41 are provided on both sides of the transition conveyor line 4 along its transmission direction, and the retaining frame 42 and the cross frame 41 are perpendicular to each other, so as to ensure that the heat exchanger 1 is fixed during the conveying process of the transition conveyor line 4 to prevent the heat exchanger 1 from falling and being damaged.
