Description
Technical field
The present invention relates to electronic devices and components welding field, particularly, relate to the long-range discharging mechanism of a kind of electronic device welding fume.
Background technology
Along with the raising of electronic product complexity, the components and parts of use get more and more, and some electronic product (especially some large scale electronic equipment) will use hundreds of thousands of components and parts, and number of welds is then thousands of.Welding is the important process in electronic product assembling process.The quality of welding quality, directly affects the service behaviour of electronic circuit and electronic installation.Excellent welding quality, can be stability, reliability that circuit provides good, bad welding method can cause component damage, brings very large difficulty, sometimes also can leave hidden danger, the reliability of electronic equipment of impact to test.And bad solder joint all can affect the reliability of whole product.Welding quality is the key of Quality of electronic products.Therefore, it is very important for grasping skilled welding operation technical ability for the technical staff of production line.
Although electronic product extensively adopts machine (wave-soldering or Reflow Soldering) to weld, in enterprise, also do not have now a kind of welding method can completely without manual welding.Even if very on a production line high in automaticity, the element always having some irregular elements or be not suitable for automatic welding element needs manual welding, another situation is that the qualification rate of machine welding does not also accomplish 100%, and the element of always some misloading, neglected loading needs to repair.Therefore manual welding technology remains the production skills of a line technology personnel indispensability.
One of instrument the most frequently used when electric iron is Electronic Assemblies, for purposes such as welding, maintenance and replacing components and parts.Electric iron has common electric iron, temp .-regulating type electric iron, constant temperature electric iron etc. several.When using electric iron, often use various scaling powder, or weldering glue, soldering paste, and fumigation can be produced in the process of melting these scaling powders, weldering glue, soldering paste with electric iron, especially when long-time continuous welding, fumigation can continue always.These fumigation are not only harmful to the health of staff, and often can smoke staff's blurred vision, even shed tears, have impact on accuracy and the manual welding quality of operation.
CN201120414317.1 discloses a kind of electric welding pen, is provided with a mini-fan, opens mini-fan in use at the insulated handle place of electric welding pen, and now the fumigation produced in welding process can dispel by mini-fan timely.But there is following problem in the program.One is that this body structure of electric welding pen is very little, if it is too little to install mini-fan thereon, wind-force is not enough to dispel fumigation, if fan is too large, can affect the hand-held electric welding pen of staff, thus impact operation.Two is mini-fans is still dispelled by fumigation at staff's close region, can affect the healthy of staff equally.
Summary of the invention
Technical problem to be solved by this invention is to provide the long-range discharging mechanism of a kind of electronic device welding fume, and this mechanism can discharge when not affecting staff carries out welding operation the fumigation that will produce in welding process.
The present invention's adopted technical scheme that solves the problem is:
The long-range discharging mechanism of a kind of electronic device welding fume, comprise negative pressure generator, fumigation suction inlet, air intake duct, fumigation suction inlet is arranged on the proximity of electronic devices and components to be welded, and fumigation suction inlet is connected by air intake duct and negative pressure generator.The program does not need the structure changing electric welding pen (electric iron), only fumigation suction inlet need be arranged on the proximity of electronic devices and components to be welded, negative pressure generator is started when welding, make to produce negative pressure near fumigation suction inlet, the fumigation produced during welding is expelled to remotely by fumigation suction inlet through air intake duct, and this mechanism does not affect staff and carries out welding operation.Meanwhile, the fumigation suction inlet of this mechanism is connected by air intake duct and negative pressure generator, better fumigation can be drained into farther place, more be conducive to the healthy of safeguard work personnel.
As a kind of structure of negative pressure generator, described negative pressure generator comprises generator body, generator body has compressed air inlet, exhaust outlet, air-breathing interface, is provided with diffusion chamber in generator body, and compressed air inlet, exhaust outlet, air-breathing interface are connected with diffusion chamber respectively; Fumigation suction inlet is connected by air intake duct and air-breathing interface.Certainly, negative pressure generator also can adopt other can produce the structure of negative pressure.
The cross section of described fumigation suction inlet reduces from the position closing on electronics to be welded unit device gradually along the direction away from electronics unit to be welded device.This structure can make fumigation suction inlet better be sucked by fumigation and be discharged by air intake duct.
Particularly, described fumigation suction inlet is the frustum cone structure of hollow, and its cross section is isosceles trapezoid.Fumigation suction inlet also can adopt similar structure.
Described fumigation suction inlet is arranged on top or the side of electronic devices and components to be welded.Certainly, according to actual welding easy construction, also can be arranged on other orientation, as above below, side, the position such as side-lower.
Described fumigation suction inlet is arranged on the proximity of electronic devices and components to be welded by fixed support.
To sum up, the invention has the beneficial effects as follows:
1, the present invention does not need the structure changing electric welding pen (electric iron), only fumigation suction inlet need be arranged on the proximity of electronic devices and components to be welded, negative pressure generator is started when welding, make to produce negative pressure near fumigation suction inlet, the fumigation produced during welding is expelled to remotely by fumigation suction inlet through air intake duct, this mechanism does not affect staff and carries out welding operation, is more conducive to the healthy of safeguard work personnel simultaneously.
2, fumigation suction inlet of the present invention is connected by air intake duct and negative pressure generator, better fumigation can be drained into farther place, more be conducive to the healthy of safeguard work personnel.
3, the cross section of fumigation suction inlet reduces from the position closing on electronics to be welded unit device gradually along the direction away from electronics unit to be welded device, and this structure can make fumigation suction inlet better be sucked by fumigation and be discharged by air intake duct.
