[0101] In this embodiment, during use, the pressing block 622 is driven by the first cylinder 621 to press the middle-stage evaporator 12, and then the bending plate 632 is driven by the second cylinder 631 so that the bending plate 632 abuts against the lower-stage evaporator 13. Then, the second cylinder 631 continuously drives the bending plate 632 until the lower-stage evaporator 13 is bent to a preset angular position, and the bending operation can be completed.

[0102] Optionally, in order to effectively position the carrier 2 when the first transfer part 31 transfers the carrier 2 and the evaporator 1 to the riveting station, the screw locking station or the bending station to meet the assembly operation requirements, the evaporator assembly machine further includes:

[0107] The jacking cylinder 103 is used to jack up the carrier 2 so that the carrier 2 is separated from the first transfer part 31.

[0108] In this embodiment, during use, the blocking part on the limiting cylinder 102 rises to block and position the carrier 2, and then the carrier 2 is jacked up by the jacking cylinder 103, so that the carrier 2 can be separated from the first transfer part 31, thereby preventing the carrier 2 from being transferred away with the first transfer part 31. In this way, the carrier 2 can be kept at the riveting station, the screw locking station or the bending station; after the assembly is completed, the carrier 2 is lowered by the jacking cylinder 103 until the carrier 2 contacts the first transfer part 31, and then the blocking part on the limiting cylinder 102 is lowered to a position separated from the carrier 2. At this time, the carrier 2 can be transferred to the subsequent riveting station, the screw locking station, the bending station or the blanking mechanism 8 by the first transfer part 31. The telescopic end of the jacking cylinder 103 is provided with a positioning protrusion matching the positioning groove at the bottom of the carrier 2 to achieve precise positioning between the jacking cylinder 103 and the carrier 2.
