PURPOSE:To enable the conveyance of the work having various widths and to prevent the pouring of a brazing material onto the unnecessary parts in the stage of working the work having a narrow width by constituting a work conveyor above a device which ejects the molten brazing material broadly and brazes printed substrates, etc. specifically. CONSTITUTION:A pair of conveyance parts 106 on both sides in the longitudinal direction in the upper part of a casing 100 of a brazing device have guide paths 107, 108 which are spaced in the transverse direction of the casing. An endless chain 110 which is passed and guided in the spacing between said paths is moved in an arrow direction, and the substrate P grasped between the clips C thereof is passed through the flux foam from a device 101 and is fed over a nozzle 59. The molten brazing material ejected from a nozzle hole 60 spreading over the entire width of the substrate by an electromagnetic pump 103 falls by colliding against the rear surface of the substrate P. When the width of the substrate P is narrow, the operator rotates a handle 125 to rotate revolving shafts 120, 121 simultaneously, thereby bringing frame bodies f1, f2 in proximity to each other. Since the width of the hole 60 is specified, the brazing material from both end parts thereof is poured on the clips and the bottom surfaces of the guide paths, but said material is blocked by a shielding plate 140 provided in the position facing the hole 60. |
