ある。 As described above, the present invention provides an outbound transfer belt above the machine frame, a return transfer conveyor below the machine frame 1, and a solvent application device and a solvent drying/heating device below the outbound transfer belt. A fluid cylinder is provided on one side of the machine frame, and a receiving device that moves up and down via a piston rod and a chain is provided on one side of the machine frame. The soldered printed circuit board and the support frame supporting the printed circuit board are transferred to the frame, which is lowered by a fluid cylinder, and the soldered printed circuit board is transferred to a go-around transfer conveyor, and this is transferred to the other side of the machine frame. The printed circuit board and its receiving frame are transferred to the receiving device of the fluid cylinder on the right side of the machine frame, and the receiving device is transferred to the receiving device of the fluid cylinder provided on the other side of the machine frame. Through the piston rod and chain, it rises and stops on the right side of the forward transfer belt, and then, while the receiving frame is locked to the forward transfer belt, the soldered printed circuit board is removed from the receiving frame, and a new unsoldered printed circuit board is removed. The circuit board is supported on a receiving frame, and the reciprocating transfer belt moves back and forth to continuously solder the printed circuit board and automatically convey it, so that the soldering of the printed circuit board can be performed continuously. At the same time, the soldered printed circuit board and the unsoldered printed circuit board are automatically returned to the starting position by the fluid cylinders installed on both sides of the machine frame and the return transfer conveyor installed between them. You can replace and solder continuously. Furthermore, the process of moving the printed circuit board back and forth, half-soldering it, and returning the soldered printed circuit board to the starting position can all be done automatically and in a circular manner, making it possible to perform the soldering work with high efficiency. At the same time, it is useful for saving labor, is accurate in operation, and is easy to operate.
