AUTOMATIC FLUX ELIMINATING MECHANISM

PURPOSE:To stabilize the soldering property by providing an engaging member which is inserted into the tip of a soldering iron, so that it can move upward and downward through sliding of a shaft, and also, providing a piston rod and a cylinder for moving the shaft. CONSTITUTION:A nozzle 2 for jetting air is provided in the vicinity of a soldering iron tip 1 of solder, and also, a fixed block 6 is placed in the lower part, and a plate 4 to which an engaging member 3 has been fixed is provided on the tip parts of shafts 5A, 5B. On the top part of the engaging member 3, an expanded open part 3A is formed, and when the soldering iron tip 1 to which a carbonized flux 11 has adhered is positioned, the engaging member 3 ascends by an operation of a cylinder, and the expanded open part 3A isolates the flux 11. Subsequently, the flux 11 is eliminated by separating the expanded open part 3A, and jetting air from the nozzle 2. Since the flux 11 can be eliminated entirely, the soldering property is stabilized.
