Abstract
The utility model relates to a double-end air knife. The double-end air knife comprises a base plate, an upper cover plate and a lower cover plate are respectively arranged on the upper side and the lower side of the base plate, an upper sealing gasket is arranged between the upper cover plate and the base plate, and a lower sealing gasket is arranged between the lower cover plate and the base plate. An upper air groove is arranged in the upper cover plate, one side of the upper air groove extends to the edge of the upper cover plate to form an upper air outlet, an upper air inlet is arranged in the upper end surface of the upper cover plate, and the upper air inlet is communicated with the upper air groove. A lower air groove is arranged in the lower cover plate, one side of the lower air groove extends to the edge of the lower cover plate to form a lower air outlet, a lower air inlet is arranged in the lower end surface of the lower cover plate, and the lower air inlet is communicated with the lower air groove. The width of the upper air outlet is larger than that of the lower air outlet. The double-end air knife is suitable for drying water and electroplated liquid on a wire frame after electroplating.
Description
Technical field
The utility model relates to the production technical field of lead frame, refers to especially a kind of double end air knife.
Background technology
Lead frame needs to use air knife that the power and water plating bath on the lead frame is dried up after electroplating in process of production.Present employed air knife is generally the single head structure, it comprises a base plate, be provided with cover plate on the base plate, be provided with sealing gasket between cover plate and the base plate, be provided with the wind groove in the cover plate, the edge that one side of wind groove is extended down to cover plate forms the air port, and cover plate is provided with air inlet in the upper surface, and air inlet is connected with the wind groove.During use, connect wind regime at the air inlet place of cover plate, wind blows out from the air outlet of the sidepiece of cover plate, realizes the blowing to lead frame.Its shortcoming is: because the width of lead frame differs, in order to be used for the widest lead frame, so the air outlet of the air knife that usually adopts is maximum, when narrower lead frame is blown, caused very large air quantity waste.
The utility model content
Technical problem to be solved in the utility model is: a kind of double end air knife that can not cause the air quantity waste is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the double end air knife, comprise a base plate, described base plate is respectively arranged with upper cover plate and lower cover in both sides up and down, is provided with sealing gasket between upper cover plate and the base plate, is provided with the lower seal pad between lower cover and the base plate, be provided with the windward groove in the upper cover plate, the edge that one side of windward groove is extended down to upper cover plate forms air outlet, is provided with enterprising air port in the upper cover plate upper surface, and enterprising air port is connected with the windward groove; Be provided with the leeward groove in the lower cover, the edge that a side of leeward groove is extended down to lower cover forms lower air outlet, is provided with lower air inlet in the lower cover lower surface, and lower air inlet is connected with the leeward groove; The width of upper air outlet is greater than the width of lower air outlet.
The beneficial effects of the utility model are: it is simple in structure, with low cost for above-mentioned double end air knife, can regulate according to the width of the lead frame of required blowing in use, thereby can not cause the waste of air quantity.

Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is the decomposition texture schematic diagram of another line of vision of the present utility model;
Among the figure: 1, base plate, 2, upper cover plate, 3, lower cover, 4, upper sealing gasket, 5, the lower seal pad, 6, the windward groove, 7, enterprising air port, 8, the leeward groove, 9, lower air inlet.
The specific embodiment
Below by specific embodiment the utility model double end air knife is described in further detail.
As shown in Figure 1 and Figure 2, the double end air knife, comprise a base plate 1, described base plate is respectively arranged with upper cover plate 2 and lower cover 3 in both sides about in the of 1, is provided with sealing gasket 4 between upper cover plate 2 and the base plate 1, is provided with lower seal pad 5 between lower cover 3 and the base plate 1, be provided with windward groove 6 in the upper cover plate 2, the edge that one side of windward groove 6 is extended down to upper cover plate 2 forms air outlet, is provided with enterprising air port 7 in upper cover plate 2 upper surfaces, and enterprising air port 7 is connected with windward groove 6; Be provided with leeward groove 8 in the lower cover 3, the edge that a side of leeward groove 8 is extended down to lower cover 3 forms lower air outlet, is provided with lower air inlet 9 in lower cover 3 lower surfaces, and lower air inlet 9 is connected with leeward groove 8; The width of upper air outlet is greater than the width of lower air outlet.
During use, can be connected with wind regime by tracheae respectively with lower air inlet 9 places in enterprising air port 7, and valve is set respectively on each tracheae, if when producing wider lead frame, can close the valve at lower air inlet 9 places, make wind enter windward groove 6, and blow out from upper air outlet, thereby realize drying up wider lead frame; If when producing narrower lead frame, can close the valve at 7 places, enterprising air port, make wind enter leeward groove 8, and blow out from lower air outlet, thereby realize drying up narrower lead frame.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
