Abstract

The present application provides a device and method for fully automatic control of selective wave soldering. The method includes: controlling the transport guide rail to drive the sliding tray to slide from the direction of the board-in guide rail to the board-out guide rail, and placing the printed circuit to be soldered on the slide tray board; when the sliding tray slides to the fixed position for spraying, control the flux sprayer to spray flux to the bottom of the printed circuit board with the preset spray strategy; control the upper and lower preheaters of the double-layer preheating mechanism to spray the flux to the printed circuit board Move closer to the designated position for preheating; control the positioning camera towards the soldering surface of the printed circuit board to take pictures and transmit them to the controller for display; control the vertical three-axis moving table to drive the soldering tin furnace for wave height correction and soldering. The invention can save flux, reduce energy consumption, and has strong consistency, repeatability, reliability and traceability of automatic wave soldering.

Description

technical field [0001] The present application relates to the technical field of soldering, in particular to a device and method for fully automatic control of selective wave soldering. 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 component...
