Abstract
The utility model relates to the crest welder technical field, in particular to a tin bath shunting net structure improvement of a crest welder. Two crest tin bathes are arranged on the crest welder,a shunting net is arranged inside the two crest bathes, two nozzles are installed at the upper end of the shunting net, a crest width adjusting plate is arranged at the upper side of the shunting net,an adjusting screw stem is arranged on the adjusting plate to adjust the crest widths of the two nozzles, and a filtering net pressure plate is provided with the crest welder and compresses the shunting net. The shunting net takes the cuboid shape as a whole, the two long side faces of the cuboid shunting net are vertically provided with flat plates and the upper top face of the cuboid shunting net is horizontally provided with a net plate, and a plurality of net plates are slanted between the flat plates at the two long faces. A plurality of separation plates are vertically fixed on the netplate at the upper top face of the cuboid shunting net, and a second net plate is fixed at the upper ends of the separation plates. By adding the shunting net into the two crest tin bathes of the full-automatic crest welder, the tin wave ejected from the two nozzles at different crest widths is continuous, even, stable and perfect, and tin oxidation amount is reduced, thereby meeting the welding requirement of various PCB boards.
Description
Technical field
The utility model relates to the crest welder technical field of automatic welding, refers in particular to a kind of molten tin bath shunting net structural improvement of crest welder here.
Background technology
Wave-soldering is the liquid solder with fusion, by with the effect of pump, form the solder wave of given shape at the solder bath liquid level, plug-in mounting the pcb board of components and parts put with conveyer chain on, pass solder wave and realize the process of solder joint welding through a certain specific angle and certain immersion depth.
The surface of crest face is all covered by one deck oxide skin, it is along nearly all keeping static on the whole length direction of solder wave, in the wave soldering process, PCB touches the surface, forward position of tin ripple, oxide skin is broken, the tin ripple of PCB front is not pushed to with having the chap pleat and advances, this illustrates that whole oxide skin and PCB move the moulding of crest welder solder joint with same speed: when holding in face of PCB enters crest, substrate and pin are heated, and before not leaving the crest face, whole PCB is immersed in the scolder, promptly by scolder institute bridging, but in the moment of leaving the crest tail end, a spot of scolder sticks on the pad owing to the effect of wetting power, and owing to capillary reason, can occur with the lead-in wire is that the center is contracted to minimum state, and the wetting power between scolder and the pad is greater than the cohesive force of the scolder between two pads at this moment.Therefore can form fullly, the solder joint of rounding leaves the excess solder of crest afterbody, because gravity falls back to Xi Guozhong, prevents the generation of bridging.
At present, the meeting existence of crest welder crest nozzle tin ripple ejection on the market is continuous evenly, not steady, will cause the bad or local tin sticky of pcb board tin sticky of welding bad like this, will cause the pcb board failure welding rate of welding to increase, and increases manufacturing cost.
The utility model content
The purpose of this utility model is, provides a kind of and can make the more steadily uniform molten tin bath shunting net structural improvement of tin ripple.
The molten tin bath shunting net structural improvement of the crest welder that the utility model provides, crest welder is provided with two crest molten tin baths, shunting net is arranged in the two crest grooves, two nozzles are installed in the shunting net upper end, be provided with the crest width adjustment plates at the shunting net upside, width adjustment plates is provided with the crest width that adjusting screw(rod) is regulated two nozzles, and shunting net is installed under the nozzle insied width adjustable plate, one head rest width adjustment plates is pushed down, and the other end is provided with pressing plate at nozzle fixed edge place.
Described shunting net integral body is cuboid, and two long side surfaces of the shunting net of cuboid are perpendicular to be provided with dull and stereotyped and last end face is put down and is provided with web plate, a plurality of web plates of oblique fire between two long side surface flat boards.
Vertically be fixed with a plurality of dividing plates on the web plate of the last end face of the shunting net of described rectangular cylindricality, be fixed with second web plate in the dividing plate upper end.
The beneficial effects of the utility model are: by set up shunting net in two crest molten tin baths of full-automatic crest welder, can make of the tin ripple continuous uniform and stable perfection of two nozzles in different crest width ejections, reduce the tin amount of oxidation, can satisfy the welding requirements of various pcb boards, can realize the purpose of Fast Installation and dismounting on the other hand, maintenance convenient for cleaning.

The specific embodiment:
Only be the utility model preferred embodiment below, do not limit protection domain of the present utility model with this.
See Fig. 1 and shown in Figure 3, the molten tin bath shunting net structural improvement of the crest welder that the utility model provides, crest welder 10 is provided with two crest molten tin baths 1, shunting net 4 is arranged in the two crest grooves 1, two nozzles 2 are installed in shunting net 4 upper ends, be provided with crest width adjustment plates 3 at shunting net 4 upsides, adjustable plate 3 is provided with the crest width that adjusting screw(rod) 6 is regulated two nozzles 2, and filter screen pressing plate 5 is installed crest welder nozzle 2 fixed edges and compressed shunting net 4.On two crest molten tin baths 1, also be provided with tin liquor pump 7, tin liquor flows to distinguished and admirable net 4 and two nozzles 2 by tin liquor pump 7 by mobilization dynamic, the direction of arrow is represented the tin liquor flow direction among the figure, and tin liquor is that tin liquor is mobile more even, more steady by shunting net 4 shunting current stabilization effects.
See Fig. 2 and shown in Figure 3, described shunting net 4 integral body are cuboid, the flat web plate 42 that is provided with of perpendicular flat board of establishing 41 of two long side surfaces of the shunting net 4 of cuboid and last end face, and web plate 42 mainly is the impulsive force of buffering tin liquor.At dull and stereotyped 41 a plurality of oblique web plates 43 of oblique fire of two long side surfaces, tiltedly the number of web plate is advisable with 3-8, and tiltedly web plate 42 is the flows that are used for controlling tin liquor, the flow unanimity of tin liquor before and after ensureing.Can change tin liquor pressure and flow velocity because of transferring wide or transferring when narrow, this structure can keep the tin liquor flow evenly in whole zone, does not have the poor of height size.
Vertically be fixed with a plurality of dividing plates 44 on the web plate 42 of the last end face of the shunting net 4 of cuboid, these dividing plates 44 can guarantee to a great extent that the tin ripple of different tin wave band ejection is more even.Be fixed with second web plate, 45, the second web plates 45 in dividing plate 44 upper ends and make that the tin liquor of gushing is more steady.Whole shunting net 4 is provided with multiple web plate, makes the tin liquor of passing through web plate flow continuously all directions uniform and stable.Adopt polylith dividing plate and web plate to connect, web plate 45 is close to width adjustment plates 3, and dividing plate 44 is used for guiding, and string is moving about when preventing the tin liquor upper punch causes the tin ripple not steady, and that guarantees that web plate 45 and width adjustment plates 3 do not contact with regionally just has a generation of tin ripple.
See shown in Figure 4ly, when needs clean shunting net, be transferred to the crest width adjustment plates 3 of two nozzles 2 the wideest, the filter screen pressing plate 5 of dismantling, whole shunting net can take out from molten tin bath 1, the whole nozzle 2 of need not dismantling during cleaning shunting net 4, thereby make cleaning, safeguard to become convenient.
