Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Such as figure 1 shown.
[0029] A gas purification device for inert gas shielded welding, which comprises a closed container 15 with a sealed door 24, and a high temperature resistant sealing strip is installed around the sealed door 24, such as figure 2 Shown, airtight container 15 is installed on the support 18, and the pulley that is convenient to dismounting is installed below support 18. An inert gas heat exchange filter 3 is installed in the airtight container 15, and the inert gas heat exchange filter 3 is fixed on the bracket 18 by a pressing mechanism 23 so as to be clamped or loosened. The air inlet 1 of the inert gas heat exchange filter 3 is connected with the air outlet of the reflow soldering furnace, and the air outlet of the inert gas heat exchange filter 3 passes through the negative pressure power mechanism 4 and the pipelin...

A gas purifying apparatus for inert gas shielded welding comprises a closed container (15) having a sealing door (24), and the closed container (15) is arranged on a support (18). An inert gas heat exchange filter (3) is arranged in the closed container (15), the gas inlet (1) of the inert gas heat exchange filter (3) is communicated with the gas outlet of a reflow soldering furnace, the gas outlet of the inert gas heat exchange filter (3) is communicated with the gas inlet of the reflow soldering furnace through an inert gas outlet (5) of the closed container (15) by installing a negative pressure actuating mechanism (4) and a pipeline (6), and cooling liquid inlet tubes (7) and cooling liquid outlet tubes (8) are arranged in the inert gas heat exchange filter (3). The gas purifying apparatus has the advantages of simple structure, small volume, convenient cleaning, obvious improvement of the welding quality, cost saving benefiting, and reduction of the application amount of the inert gas.
Description
technical field [0001] The invention relates to a welding technology, especially a gas purification device used in the inert gas shielded welding technology to purify and recover the inert gas and recover flux at the same time, specifically an inert gas shielded welding gas Purification device. Background technique [0002] At present, when surface mount technology enters automatic production, the awareness of environmental protection is strengthened, and electronic products basically use lead-free solder paste. Because the fluidity, solderability and wettability of lead-free solder paste are not as good as those of lead-based solder paste, especially now that high-end electronic products are developing towards miniaturization, chip components are getting smaller and smaller, chip stacking technology is continuously improving, and chip stacking layers The number can be increased to 8 layers according to the designer's requirements, and the chips and circuit boards are getti...
