PURPOSE:To provide a titled device which is compact and stabilizes working quality by arranging and installing respective stage working machines densely along the lower part of a work transfer route and immersing the work into tanks in the ascending mode of the required working machines. CONSTITUTION:A conveyor 3 which conveys the work is turned cyclically intermittently between a stage moving route (a) and a return moving route (b). After the command for starting said line is operated, a holding plate 8 which holds the work W is first stopped above a flux tank 10. A vessel 16 ascends in a prescribed time limit to immerse the work W in the soln. in the tank 10, after which the vessel 16 is lowered and the plate 8 is moved again. Next, when the plate 8 passes above the heaters 19A-19C of a heater 11, it is heated successively, after which it is stopped above a solering tank 12, and a vessel 27 is moved upward and downward plural times; at the same time the work W is dipped repeatedly into molten solder. Next, the plate 8 is stopped above a pre-washing chamber 38 of a washing tank 13 in the similar manner, and is pre-washed, after which it is stopped above a finish washing chamber 38, where it is finish washed. The plate 8 holding the work W completed of the working is removed from a bar 6 and the work W is separated from the plate 8. |
