Abstract

The invention provides a full-automatic selective wave soldering device which comprises a transportation guide rail, a scaling powder spraying mechanism, a double-layer preheating mechanism, a selective soldering mechanism and a controller. The transportation guide rail is provided with a spraying fixing position, a preheating fixing position and a soldering fixing position, and is provided with asliding tray sliding along a board inlet guide rail and a board outlet guide rail, and a printed circuit board to be soldered is placed on the sliding tray. The scaling powder spraying mechanism is located at the spraying fixing position and located below the sliding tray and comprises a vertical double-axis moving table and a scaling powder sprayer. The double-layer preheating mechanism is located at the preheating fixing position and comprises an upper preheater and a lower preheater. The selective welding mechanism is located at the welding fixing position and located below the sliding tray and comprises a vertical three-axis moving table and a soldering tin furnace. The controller is connected with the conveying guide rail, the scaling powder spraying mechanism, the double-layer preheating mechanism and the selective welding mechanism. By means of the full-automatic selective wave soldering device, scaling powder can be saved, energy consumption is reduced, and automatic wave soldering with high consistency, repeatability, reliability and traceability is achieved.

Description

technical field [0001] The present application relates to the technical field of soldering, in particular to a fully automatic selective wave soldering device. Background technique [0002] Wave soldering is a welding process that makes the soldering surface of the plug-in board directly contact with high-temperature liquid tin. The high-temperature liquid tin maintains a slope, and a special device makes the liquid tin form a wave-like phenomenon, so it is called "wave soldering". Its main material is solder bar. With the high density and miniaturization trend of electronic product production process, the surface mount technology (Surface Mounted Technolog, abbreviated as SMT) technology develops rapidly, the traditional wave soldering process can no longer meet the welding needs of the remaining few perforated components, and manual It is difficult to achieve high-quality and high-efficiency welding for large heat capacity or fine-pitch components, and the cost advantage ...
