Method for the insertion of bends in pipes for fluid of a heat exchanger

The present invention concerns a method for the insertion of bends in pipes for fluid of a heat exchanger in which there are the steps of generating a light radiation to light up a side (112b) of a heat exchanger (100), acquiring a first image (img1) representing the side (112b) of the exchanger (100), graphically processing the first acquired image (img1) to identify first pixels (p1) corresponding to a graphical representation of the terminal ends (113a, 113b) of the pipes (113) in the first acquired image (img1), calculating, with respect to a reference system, the coordinates of the axis of the terminal ends (113a, 113b) as a function of the first pixels (p1) identified, generating a control signal (sc) and sending the control signal (sc) to an apparatus (50) for the insertion of the bends (114); as a function of the value of the calculated coordinates to control the movement of the apparatus (50) along the side (112b) of the exchanger (100) in order to insert the bends (114) into the terminal ends (113a, 113b) of the pipes (113) of the heat exchanger (100).
