Abstract
A heat exchanger production line is provided, which includes a support frame, a fin conveying line, as well as a fin storing-fetching device, an end plate mounting device, a pipe inserting device and a nitrogen charging device which are arranged at corresponding positions of the fin conveying line. The fin storing-fetching device is arranged at one end of the fin conveying line. The fin storing-fetching device includes a storing-fetching bracket, a bottom plate, a lifting support plate and a feeding robot. A fin stack is transferred to the fin conveying line by the fin storing-fetching device, is then sequentially conveyed to corresponding stations to be processed along with the fin conveying line, ultimately forming a heat exchanger.
