Automatic expanded connection system and control method

The invention discloses an automatic expanded connection system and a control method, and the system comprises an expanded connection module which enables a heat exchange tube of a heat exchanger to be expanded through expanded connection and to be attached to a tube plate; the visual module is used for acquiring position parameters of the tube plate and tube hole center position parameters of the heat exchange tube; the carrying module is used for moving the expanded connection module and the visual module; and the controller is used for setting a moving path of the expanded connection module according to the position parameters of the tube plate and the central position parameters of the tube holes, and controlling the expanded connection module to perform expanded connection on each tube hole of the heat exchanger. The tube expansion module is moved through the double robots, the running path is set in advance in a visual positioning mode to conduct expansion connection on tube holes in a tube plate of the
