Adopt this structure, owing to will smoothly can flow above torrent portion 10 and the synthesis of turbulent waves stream, therefore, it is possible to the roughness on the surface of adjustment turbulent waves stream, and fusion welding can also be injected fully to through hole.Thereby, it is possible to provide the spout nozzles that the multi-functional reliability of band is high.And, utilize the pressure (dispersion) from below, the phenomenon that fusion welding flows out from solder bath upper propagation such as the delivery tray frames of printed base plate, lift-launch printed base plate (installation base plate) can be avoided.Also torrent ripple can be utilized to strengthen fusion welding to the surface pressing of substrate.Especially, obtain and also most suitable nozzle arrangements is carried for long lead device, reply pallet.
the example of the structure of jet flow welder 200
Next, be described with reference to the example of Fig. 5 to the structure of jet flow welder 200.Jet flow welder 200 shown in Fig. 5 is the examples forming jet apparatus, and it, to the predetermined surface jet flow fusion welding 7 of printed base plate 1, welds electronic device to this printed base plate 1.In addition, the y in figure is substrate throughput direction, with the nozzle width direction Y-direction shown in Fig. 1 in the same way.
Jet flow welder 200 comprises pipeline 41, pump case 43, pump 50, solder bath 51, motor 60 and spout nozzles 100.Solder bath 51 is the housing of upper surface open, is accommodated with fusion welding 7.This solder bath 51 is provided with not shown heater, fusion welding 7 is remained on stationary temperature.Pipeline 41 and pump case 43 are installed on solder bath 51 in the mode that impregnated in fusion welding 7.
Pipeline 41 has the main part 401 of thin-long casing, is provided with nozzle connector 402 on the top of main part 401.Main part 401 is connected with pump case 43, is accommodated with pump 50 in pump case 43, and this pump 50 carries out action to suck fusion welding 7 and to be carried to prescribed direction by this fusion welding 7.The rotating shaft of pump 50 is provided with belt wheel 52.Pump 50 also can use the pump of vane type except using helical type pump.
Be equipped with motor 60 in the assigned position of the outside of solder bath 51, in the axle portion of motor 60, belt wheel 53 be installed.Between the belt wheel 52 and the belt wheel 53 of motor 60 of said pump 50, be wound with driving-belt 54, if motor 60 rotates to prescribed direction, then driving-belt 54 is driven to rotate, and pump 50 rotates.Pump 50 carries out action to be pressed in pipeline 41 by fusion welding 7.Thus, pipeline 41 guides fusion welding 7 towards spout nozzles 100.
Said nozzle connecting portion 402 is connected with spout nozzles 100.Spout nozzles 100 uses multifunctional nozzle of the present invention.Spout nozzles 100 is taken into fusion welding 7 from below, and sprays fusion welding 7 upward.In this example, jet flow fusion welding 7 on the printed base plate 1 carried to the top of nozzle body 42.Therefore, jet flow welder 200 is formed.
Next, be described with reference to the example (its 1 ~ 3) of Fig. 6 ~ Fig. 8 to the action of jet flow welder 200.Jet flow welder 200 shown in Fig. 6 ~ Fig. 8 is the cutaway views extracting the periphery of pipeline 41 and spout nozzles 100 from the jet flow welder 200 shown in Fig. 5 out.
In the example of this action, about a spout nozzles with multiple aperture portion, compare two kinds of situations and investigate its effect, these two kinds of situations are respectively: the transporting velocity of printed base plate 1 is kept constant, make the jet speed of fusion welding 7, pressure etc. variable and adjust the situation (mode in the past) of jet flow amplitude; Use the function of perforated panel 13+ guide portion 24+ aperture variable mechanism 90 of the present invention and the situation (mode of the present invention) that the roughness on the surface in torrent portion 10 is finely tuned simultaneously.
In this example, the major function of overflow plate 25 is the overflows stoping level and smooth stream, by adjusting the height α of overflow plate 25, the inducing function that the induction to torrent portion 10 can be made smoothly to flow is " having or nothing ", can finely tune in addition to the roughness on the surface in torrent portion 10.According to this surface roughness adjustment function, by adjusting the height α of overflow plate 25 relative to flat member 23 in advance, the guiding amount that smoothly flows of the guiding in subtend torrent portion 10 can adjust, the roughness on the surface in torrent portion 10 is finely tuned.
The example (its 1) of the action of the jet flow welder 200 according to Fig. 6, for setting the function of regulating height thereof of guide portion 24 thus making overflow plate 25 in the situation of the position (α=0) of bottom.In addition, be such state: setting aperture variable mechanism 90 thus make advection portion 20 close to the inside and jet flow A/F W φ is W φ=MIN relative to torrent portion 10.In mode of the present invention, the example (its 1 ~ 3) of 3 actions jointly, is constant mode CD-ROM drive motor 60 with the power output of pump 50.Therefore, jet flow height h is constant.Above-mentioned height α=0 (position of bottom) is the position of the datum level forming jet flow height h in advection portion 20.
Adopt these to set, when fusion welding 7 is fed to spout nozzles 100 from pipeline 41, becomes and shunt at the outlet 602 of spout nozzles 100 to torrent portion 10 and side, advection portion 20 and carry out the state of jet flow.Because overflow plate 25 is fixed on the position of bottom, the fusion welding 7 therefore shunted to the side in advection portion 20 flows out to side, downstream (spillway discharge is large, and guiding amount is zero substantially).In torrent portion 10, become following state: the vertical ripple (33 place) of fusion welding 7 from perforated panel 13 jet flow, and flows to the root of vertical ripple from the fusion welding 7 that outlet 602 is shunted to side, torrent portion 10.In this state, the guiding amount due to the level and smooth stream guided to torrent portion 10 from advection portion 20 is equivalent to substantially not have, and the convex-concave of the vertical ripple therefore in torrent portion 10 becomes many (becoming remarkable).
The example (its 2) of the action of the jet flow welder 200 according to Fig. 7, adjusts the height α of guide portion 24 thus makes overflow plate 25 in centre position.Such as, to give prominence to the height α fixed weir plate 25 of α 1 (α 1>0) from the end in advection portion 20.Aperture variable mechanism 90 is all W φ=MIN mutually with the example of the action shown in Fig. 6.In this case, compared with the example (its 1) of action, overflow plate 25 gives prominence to α 1, therefore compared with Fig. 6 from the end in advection portion 20, the quantitative change that the fusion welding 7 shunted to the side in advection portion 20 flows out to side, downstream few (spillway discharge is medium, and guiding amount is medium).
Become following state: in torrent portion 10, the fusion welding 7 that the side from outlet 602 to torrent portion 10 has been shunted flows to the root of vertical ripple with by guiding a part for the fusion welding 7 come to collaborate from advection portion 20.In this state, because the guiding quantitative change of the level and smooth stream guided to torrent portion 10 from advection portion 20 is many, the convex-concave of the vertical ripple therefore in torrent portion 10 tails off (becoming not remarkable gradually).
The example (its 3) of the action of the jet flow welder 200 according to Fig. 8, adjusts the height α of guide portion 24 thus makes overflow plate 25 in the position of the top.Such as, to give prominence to the height α fixed weir plate 25 of α 2 (α 2> α 1) from the end in advection portion 20.Situation for such: compared with the example of the action shown in Fig. 6 and Fig. 7, aperture variable mechanism 90 is set as W φ=MAX.
In this case, compared with the example (1,2) of action, overflow plate 25 gives prominence to α 2 from the end in advection portion 20, therefore compared with Fig. 6, the amount flowed out to side, downstream of the fusion welding 7 shunted to side, advection side 20 does not have completely, becomes the state (spillway discharge is zero, and guiding amount is maximum) of the side being all directed to torrent portion 10, in this state, the convex-concave of the vertical ripple in torrent portion 10 becomes almost not to be had (basic change is not remarkable).
On the other hand, adopt a spout nozzles with the mode in the past of multiple aperture portion, confirm the outflow of fusion welding 7.In addition, the excessive dipping of fusion welding 7 as a result, confirm fusion welding via the steam vent of substrate, through hole to device side side excessive outstanding state.To this, when of the present invention comprise the spout nozzles 100 of the function of perforated panel 13+ guide portion 24+ aperture variable mechanism 90 time, when fusion welding 7 contacts to printed base plate 1, the outflow to fusion welding 7 unconfirmed.
Like this, adopt the jet flow welder 200 of execution mode, because it comprises the spout nozzles 100 with several functions of the present invention, the face that is attached that therefore can not only maintain printed base plate 1 is exposed to the state of the fusion welding 7 of jet flow shape, can also prevent fusion welding 7 from propagating in the framework of delivery system etc. and flowing out such state of affairs.In the above example, vertical ripple and level and smooth stream offset and prevent the outflow of fusion welding 7.Therefore, it is possible to provide the jet flow welder 200 with a high spout nozzles of reliability.
Therefore, it is possible to fusion welding 7 to be attached to well the pore portion such as through hole, contact hole of the connection of printed base plate 1.Thereby, it is possible to the transporting velocity of printed base plate 1 to be set as the faster level of mode than ever, the productivity ratio of this device can be improved.
In the above example, only the situation that the object of welding is printed base plate is illustrated, but is not limited in this.Object for welding is the situation of the pallet conveying of carrying printed base plate (installation base plate) etc., also can obtain same effect.
utilizability in industry
