Abstract
The invention relates to an air cooling type soldering flux gathering device for a reflow soldering furnace. The air cooling type soldering flux gathering device for the reflow soldering furnace comprises a smog-shaped soldering flux input hole, an air cooling type heat exchanger, a shell, a filtered gas output hole and a soldering flux gathering cup, the air cooling type heat exchanger is distributed in the shell, the smog-shaped soldering flux input hole and filtered gas output hole are respectively formed in the air cooling type heat exchanger, and the soldering flux gathering cup is arranged at the cooling air end of the air cooling type heat exchanger; after the smog-shaped soldering flux enters the air cooling type heat exchanger through the smog-shaped soldering flux input hole, when passing the air cooling type heat exchanger, the soldering flux is gathered in the soldering flux gathering cup after being condensed by cold, and the filtered gas is output through the filtered gas output hole. Compared with the prior art, the air cooling type soldering flux gathering device for the reflow soldering furnace has advantages of simple structure, compact design, low cost, easiness in maintenance and the like.
Description
Technical field
The present invention relates to a kind of reflow soldering correlation technique, especially relate to a kind of ventilation type soldering flux collection device for reflow soldering.
Background technology
Reflow soldering is the equipment for welding the circuit board being loaded with surface mount device or punctured element.It is by providing a kind of heating environment, solder(ing) paste is heated and melts thus allow surface-pasted components and parts and circuit board reliably be combined by solder(ing) paste alloy.But for helping the scaling powder welded can volatilize along with the rising of temperature while welding, at high temperature scaling powder is smoke-like, if but in cooling zone due to the sharply decline of temperature (differing 120 degrees centigrade on the thermal treatment zone greatly), then become the scaling powder of smoke-like can form glue in condensation and be attached to cooling zone, after reaching certain quality, drip due to the effect of gravity, there is the possibility polluting the PCB welded.In addition in welding owing to needing to prevent the oxidation of element pad or element under high temperature, occur so partial reflux stove in the market can pour the anti-oxidation of nitrogen.So the general capable collection of the scaling powder of nitrogen furnace many uses water-cooled soldering flux collection device to smoke-like, its principle is that the scaling powder of smoke-like is blown into the collecting box that heat exchanger is housed, after the scaling powder chance of high temperature is cold, condensation on the heat exchanger, play the effect of collection with this, the gas through filtering then needs to return cooling zone to be made nitrogen can be recycled to prevent unnecessary waste.But because the multiplex cold water of this type of heat exchanger carries out heat exchange, so the hardware device of frozen water machine or external cold water or facility essential, overall equipment funds drop into corresponding increase (reflow ovens joins a frozen water machine), in addition in order to do not allow frozen water machine discharge in operation the workshop that directly do not discharge of hot-air, also need separately for exhaust system installed by frozen water machine, thus considerably increase cost.
Summary of the invention
Object of the present invention be exactly provide that a kind of structure is simple, compact to design, cost is low to overcome defect that above-mentioned prior art exists, maintenance is simply for the ventilation type soldering flux collection device of reflow soldering.
Object of the present invention can be achieved through the following technical solutions:
A kind of ventilation type soldering flux collection device for reflow soldering, it is characterized in that, comprise gas delivery port and scaling powder collection cups after smoke-like scaling powder input port, air-cooled type heat exchanger, shell, filter, described air-cooled type heat exchanger distribution in the enclosure, described smoke-like scaling powder input port and the rear gas delivery port of filter are arranged on air-cooled type heat exchanger respectively, and described scaling powder collection cups is located at the cold wind end of air-cooled type heat exchanger;
After smoke-like scaling powder enters air-cooled type heat exchanger by smoke-like scaling powder input port, during by air-cooled type heat exchanger, scaling powder is taken in scaling powder collection cups after meeting condensation knot, and the gas after filtration is exported by gas delivery port after filter.
Described air-cooled type heat exchanger is the heat exchanger with fin.
Described air-cooled type heat exchanger is provided with multiple, equidistantly distributes in the enclosure.
Described scaling powder collection cups is identical with the quantity of air-cooled type heat exchanger, and the cold wind end of each air-cooled type heat exchanger is equipped with a scaling powder collection cups.
Compared with prior art, the present invention has the following advantages:
1, structure is simple, compact to design, and same use heat exchange as design fundamentals, but employs the input that air cooling way saves ancillary equipment cleverly.Highly versatile, directly can install additional, not affect overall appearance on existing stove.
2, cost is low, customer equipment and factory's business facility less investment, owing to employing air cooling way, so need not purchase frozen water machine in addition or provide factory's business frozen water, decreases fund input and construction budget.
3, maintenance is simple, owing to only needing clean flux machine collection cups and mechanical cleaning filter, decreases use solvent, which saves manpower and materials and the financial resources of maintenance, also advocated environmental protection.
