Abstract

The invention relates to an automatic welding device of a circuit board welding machine. The automatic welding device comprises an outer shell, a guiding pipe, branch pipes and a nozzle. The outer shell of the welding device is fixedly mounted at the lower end of a sliding arm, and the guiding pipe is coaxially mounted in the outer shell; the upper end of the guiding pipe is communicated with a hot air input device in a sealed mode, and the lower portion of the guiding pipe is communicated with multiple branch pipes in a sealed mode; the lower end of the guiding pipe penetrates through the lower end face of the outer shell and is connected with the nozzle in a sealed mode. According to the nozzle of the automatic welding device, a high-temperature soldering tin spraying mode is adopted, the control over the amount of the soldering tin can be achieved by controlling the flow of high-pressure gas, and pressure difference generated by high-speed air flowing is used for spraying the soldering tin so as to weld direct-plugging elements, so that the soldering tin is prevented from being bonded to the nozzle, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the field of circuit board welding, and relates to the welding of in-line electronic devices, in particular to an automatic welding device of a circuit board welding machine and a welding method thereof. Background technique [0002] The components on the circuit board are divided into patch type and in-line type. The in-line device welding method is: use an electric soldering iron to melt the solder, use gravity and fluidity of the liquid to flow the solder into the solder joint hole, and wait for the solder to naturally Secure the in-line inserts after cooling. The welding efficiency of this method is low, and the liquid solder has a certain viscosity and sticks to the tip of the soldering iron and is not easy to fall off. The tip of the soldering iron is easy to oxidize, and the introduction of impurities affects the welding quality. The high temperature of the soldering iron is easy to burn components and circuit boards. ...
