Common-rail double-speed wave-soldering conveying device

The utility model relates to the technical field of conveying devices, in particular to a common-rail double-speed wave soldering conveying device which comprises a shell, a first conveying mechanism, a second conveying mechanism, a spraying mechanism, a preheating mechanism, a tin dipping mechanism and a controller. The preheating mechanism is installed at the upper right end of the first conveying mechanism, the tin dipping mechanism is installed on the second conveying mechanism, detectors are arranged at the right end and the left end of the first conveying mechanism, and the first conveying mechanism and the second conveying mechanism are driven by motors. The detector and the motor are both electrically connected with the controller; the first conveying mechanism and the second conveying mechanism are adopted, the machining time of the spraying mechanism, the preheating mechanism and the tin immersion mechanism can be selected according to needs, spraying, preheating and tin immersion are integrated, th
