ABSTRACT:
A machine for determining the location of junction tubes along a header and automatically brazing them to the header. A chassis is employed to hold the junction tubes and header in the proper orientation. A carriage then travels along a line which is parallel to the central axis of the header. The carriage includes a sensor which is able to determine the exact position of the junction tubes. This positional information is stored in a controller. The carriage also includes a reciprocating pair of burners for heating the joint to be brazed. A pair of brazing wire feeders are included for feeding the brazing alloy alloy to the joint. A pyrometer is also included for measuring the temperature of the joint during the brazing process. In operation, the carriage slides along with the sensor measuring the position of each joint to be brazed. The burners and brazing alloy feeders are located in such a position on the carriage that the sensor precedes them in coming to each joint location. Thus, the joint location is determined, then the carriage is moved to bring the burners in contact with the joint. Once in position, the burners are moved through a reciprocating motion to evenly heat the joint. A pyrometer is used to monitor the joint temperature (through the operation of the controller). When the appropriate temperature is reached, the controller causes the brazing wire feeders to feed the appropriate amount of brazing alloy to the joint—thereby brazing the joint. The carriage then moves on to the next joint position. The process is repeated until every joint on the header has been brazed.
