Description
Technical field
The utility model relates to a kind of wave-soldering welding equipment.
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 the wave-soldering welding equipment to the circuit board of handling well and weld.The wave-soldering welding equipment 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 liquor 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 utility model provides the weldering of a kind of company of preventing, improves the wave-soldering welding equipment of welding quality.
For achieving the above object, the utility model provides a kind of wave-soldering welding equipment, comprise body, one end is connected with body, the anchor clamps that are used for the clamping circuit board, be arranged on the tin cream containing cavity of internal body, the Hu Kou that is arranged at tin cream containing cavity top and is connected with the tin cream containing cavity, also be provided with a baffler, a plurality of flow-guiding channels that parallel setting that baffler has the tin cream recycling cavity and is connected with the tin cream recycling cavity, the diameter of each flow-guiding channel is 2.43mm, 2.43mm it is little that wide flow-guiding channel not only takes up room, and effectively guide tin liquor, utilizes resource fully.
More excellent, the quantity of flow-guiding channel is 3, has not only effectively controlled the baffler volume, and each flow-guiding channel is additional mutually, has guaranteed the water conservancy diversion effect.
More excellent, the end diameter that flow-guiding channel is connected with the tin cream recycling cavity is greater than the diameter away from an end of tin cream recycling cavity, guarantees can not stop up because of the flow-guiding channel at rear portion and not influence the water conservancy diversion effect of anterior flow-guiding channel, guarantees that the baffler operation is normal.
More excellent, baffler on body, uses screw that the tin cream recycling cavity is fixed by screw, and low price is simple to operate, is connected firmly, and is easy to maintenance.
The advantage of wave-soldering welding equipment of the present utility model is: 1, increase by a baffler, the diversion division of baffler contact with solder side, plays a part to guide, and in time that weld is unnecessary tin cream is led away, thus the company of preventing weld, guaranteed the welding quality of solder joint. 2, the wide flow-guiding channel of 2.43mm not only takes up room for a short time, and effectively guides tin liquor, utilizes resource fully.
Description of drawings
Fig. 1 is the vertical view that comprises the utility model wave-soldering welding equipment.
Among the figure
The 1-anchor clamps, 2-Hu Kou, 3-tin cream containing cavity, 4-body, 5-flow-guiding channel, 6-baffler, 7-tin cream recycling cavity.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection range of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
As shown in Figure 1, a kind of wave-soldering welding equipment, comprise body 4, one end is connected with body 4, the anchor clamps 1 that are used for the clamping circuit board, be arranged on the tin cream containing cavity 3 of body 4 inside, the kettle mouth 2 that is arranged at tin cream containing cavity 3 tops and is connected with tin cream containing cavity 3, also be provided with a baffler 6,3 flow-guiding channels 5 that parallel setting that baffler 6 has tin cream recycling cavity 7 and is connected with tin cream recycling cavity 7, the diameter of each flow-guiding channel 5 is 2.43mm, 2.43mm wide flow-guiding channel 5 not only takes up room little, and effectively guide tin liquor, utilize resource fully.
The end diameter that flow-guiding channel 5 is connected with tin cream recycling cavity 7 is greater than the diameter away from an end of tin cream recycling cavity 7, flow-guiding channel 5 is the big shape in little bottom, top, make tin cream enough to the time of person who lives in exile's tin cream recycling cavity 7, guaranteed the smoothness of tin cream circulation from flowing into flow-guiding channel 5.
On body 4, the quantity of screw is 2 to baffler 6 by screw, runs through tin cream recycling cavity 7 from tin cream recycling cavity 7 tops, baffler 6 is fixed, used screw tin cream recycling cavity 7 to be fixed low price, simple to operate, be connected firmly, easy to maintenance.
The operation principle of wave-soldering welding equipment of the present utility model is as follows:
The flow-guiding mouth of the flow-guiding channel 5 of diversion division is placed on and closes on kettle mouth 2 places, the wave-soldering welding equipment blows out tin cream from kettle mouth 2, form the tin post at kettle mouth 2 places, anchor clamps 1 clamping circuit board is through kettle mouth 2 tops, the tin cream that kettle mouth 2 blows out contacts with circuit board, because capillary existence, the tin cream upper surface becomes spherical shape, the tin cream of spherical shape will touch the flow-guiding mouth top of the flow-guiding channel 5 of diversion division, tin cream flows into tin cream recycling cavity 7 along flow-guiding channel 5, in time tin unnecessary on the circuit board is derived and go, thereby the tin cream amount that guarantees the circuit board place is normal, the situation that tin cream between adjacent two solder joints links together can not take place, and the company of preventing welds, and has guaranteed the welding quality of solder joint.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
