Abstract
The invention provides a deflector comprising a deflecting part (2) provided with a plurality of deflecting channels, an accommodation chamber (1) and a fixed part, wherein the accommodation chamber (1) is arranged below the deflecting part (2) and is communicated with the deflecting part (2); the fixed part is connected with the accommodation chamber (1); and the deflecting part (2) is provided with a bent part. The deflector has the advantages of preventing the connected welding and improving the welding quality.
Description
Technical field
The present invention relates to a kind of deflector, relate in particular to a kind of deflector that is used for crest welder.
Background technology
Wave-soldering is meant the solder with fusing, be generally terne metal, become the solder wave of designing requirement through electrodynamic pump or electromagnetic pump jet flow, also can be by forming to the solder pot nitrogen injection, make the printed board that components and parts are housed in advance by solder wave, realize machinery and the solder that is electrically connected between components and parts weldering end or pin and the printed board pad.
Wave-soldering need be placed on crest welder to the circuit board of handling well and weld.Crest welder is by the spray scaling powder, and circuit board preheating and wave soldering three parts are formed, and its major part is a wave soldering, and principle is that the tin that melts is blown out by the aperture on the jet plate with gas according to actual needs, finally finishes welding.Wave-soldering solder joint gloss seldom has rosin joint, and advanced can also own handle the components and parts pin.
Tin cream is loaded in the tin stove, and during wave soldering, tin cream welds circuit board from the ejection of tin furnace roof end.Under the prior art, after tin cream sprays from Hu Kou, form the tin post at the Hu Kou place, because capillary existence, the tin cream upper surface becomes spherical shape, when finer and closely woven as if the electric elements that weld, the accumulation of tin post ball causes connecting weldering easily, finally causes the electric elements heavy industry, and the yield of production is low.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the weldering of a kind of company of preventing, improve the deflector of welding quality.
For achieving the above object, the invention provides a kind of deflector, comprise diversion division, be arranged on diversion division below and the chamber resettling that is connected with diversion division with a plurality of flow-guiding channels, the fixed part that is connected with chamber resettling, diversion division has a kink.
More excellent, fixed part is to run through the hole of chamber resettling and the screw that matches with the hole, uses screw that chamber resettling is fixed, low price is simple to operate, is connected firmly, and is easy to maintenance.
More excellent, a plurality of flow-guiding channels be arranged in parallel, and easy with parallel solder joint cooperates the purpose that reaches drainage, water conservancy diversion effective.
More excellent, the quantity of flow-guiding channel is 3, has not only effectively controlled the deflector volume, and each flow-guiding channel is additional mutually, has guaranteed the water conservancy diversion effect.
The advantage of a kind of deflector of the present invention is: the diversion division of deflector contacts with solder side, plays guiding, and in time that weld is unnecessary tin cream is led away, thus companys of preventing weld, guaranteed the welding quality of solder joint.
Description of drawings
Fig. 1 is the vertical view of deflector of the present invention;
Fig. 2 is the left view of diversion division in the deflector of the present invention.
Among the figure
1-chamber resettling, 2-diversion division, 3-screw.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As shown in Figures 1 and 2, a kind of deflector is used for the water conservancy diversion tin cream, comprises the diversion division 2 with 3 flow-guiding channels, the fixed part that be arranged on diversion division 2 belows and the chamber resettling 1 that is connected with diversion division 2, is connected with chamber resettling 1.Diversion division 2 has a kink, so that extend to the optional position, chamber resettling 1 can be placed into than the position away from wave-soldering Hu Kou.
Fixed part is to run through the hole of chamber resettling 1 and the screw 3 that matches with the hole, and screw 3 is 2, runs through chamber resettling 1 from chamber resettling 1 top, deflector is fixed, used 3 pairs of chamber resettling 1 of screw to fix low price, simple to operate, be connected firmly, easy to maintenance.
In the present embodiment, deflector is provided with 3 flow-guiding channels and each flow-guiding channel for being arranged in parallel, and has not only effectively controlled the deflector volume, and each flow-guiding channel replenishes mutually, has guaranteed the water conservancy diversion effect.
The operation principle of deflector of the present invention is as follows:
The flow-guiding channel mouth of diversion division 2 is placed on and closes on the Hu Kou place, crest welder blows out tin cream from Hu Kou, form the tin post at the Hu Kou place, because capillary existence, the tin cream upper surface becomes spherical shape, the tin cream of spherical shape will touch the flow-guiding channel mouth top of diversion division 2, tin cream flows into chamber resettling 1 along the flow-guiding channel mouth, in time unnecessary tin is derived and go, thereby the tin cream amount that guarantees the to-be-welded elements place is normal, the tin cream that can not take place between adjacent two solder joints links together, and the company of preventing welds, and has guaranteed the welding quality of solder joint.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
