Abstract
The utility model relates to a tin suction device used for sucking out and recovering waste melted tin when assembling lines in electronic industry and a repairing department dismounts or replaces components. The tin suction device adopts the structure principle of a hand-driven suction pump, the external shape is formed and assembled by two injection mold components, a pump body (4) and an end cap (9), and the lower end of the tin suction device is provided with a suction nozzle (10). When the utility model is used, a control bolt (2) is pressed, under the action of a pressure spring (6), a sealing ring (5) and a tin passing bar (8) are driven to move upwards quickly by a piston rod (1), which results in negative pressure in the pump body (4), and the waste melted tin is sucked into the suction nozzle. The piston rod is pressed down until the tin passing bar (8) exposes a suction nozzle hole, the waste tin is pushed out and recovered, and the inner wall of the suction nozzle is cleared, which guarantees the passage of the suction nozzle.
Description
The utility model is used for electronics industry assembly line and repairing department, when dismounting and replacing components and parts, and the useless instrument that melts tin of sucking-off and recovery.Belong to the electronic tool field.
The connection of components and parts and printed wiring board all is to adopt soldering technology in the electronics industry.When dismounting or replacing components and parts, the essential flatiron of using earlier behind the taking-up components and parts, should be removed the useless molten tin of recovery to melts soldering tin, can guarantee Singapore dollar device mounting and welding quality.The instrument of finishing this work at present is with a kind of suction tin rope with fine wire braiding, inhales tin by its capillarity and new absorption, inhales the tin amount not quite and only with once costing an arm and a leg.Another kind of instrument is to add a metal tube on special solder horn top, and a rubber ball is adorned on top, forms a kind of suction tin flatiron.Time spent needs to connect earlier can use after power supply heats flatiron.And all be to adopt the lightweight flatiron in real work, once finding wrong weldering, when leaking weldering or repairing, must use instead again to inhale the tin flatiron and need treat and to use after its heating, in addition because it inhales tin, tell the tin work personnel selection hand rubber ball that contracts and finish, it is less to inhale the tin amount, very easily adhere to molten tin in the suction pipe and result in blockage, rubber ball is also aging easily.
The purpose of this utility model is that a kind of novel solder sucker that uses original Welding iron work without power supply will be provided, it can effectively remove and reclaim the useless molten tin on the printed wiring board, has the function of clearing up the suction nozzle inwall voluntarily, prevent that the suction nozzle obstruction from guaranteeing that suction nozzle work is unimpeded, and can on solder sucker, select corresponding suction tin amount for use according to what of useless molten tin.
The purpose of this utility model is to realize like this, solder sucker adopts the manual suction pump principle, in the circular pump housing, be equipped with on its annular groove face of a piston rod and be with sealing ring, the lower end is fixedly connected with the logical tin bar of the relatively poor stainless steel of sticking tin, but there are the two strap saw serrate slot limited piston throw of lever sizes upper end for rectangle sides, thereby how much control inhales the tin amount, the push button journey controller is contained on the pump housing, pump housing lower end is paid with end cap with spiral and is connected firmly, and high temperature resistant about 250 ℃ polytetrafluoroethylene (PTFE) suction nozzle is equipped with in the end cap lower end.Being with protective cover in the pump housing of upper end enters in the pump housing chamber with the useless tin bits that prevent to fly into.Press journey controller during work, piston rod drives sealing ring, push rod and moves on quick under the effect of compression spring simultaneously, makes and forms negative pressure in the pump housing and the suction nozzle, in useless molten tin suction suction nozzle.Drive push rod by lower piston rod then and move down, can push the useless molten tin in the suction nozzle in the useless tin cylinder and regain until exposing the suction nozzle aperture.
The utility model is owing to adopt piston type aspiration pump structural principle, so performance is reliable especially, it is big to inhale the tin amount, simultaneously because sealing ring, logical tin bar all is contained on the piston rod, its upper end is played the effect of work push rod again, and with the same stage clip source that is used as power, same Stroke Control bolt control work, so structure is simple especially, volume is especially little, energy break-through suction nozzle when pressing owing to the logical tin bar of the stainless steel that a sticking tin difference is arranged in addition, release useless molten tin and the effect of cleaning suction nozzle inwall so can play, guarantee that suction nozzle is unimpeded can not stop up; Especially because the piston rod upper end has two travel limits grooves, so can choose the different tin strokes of inhaling according to need of work.
The concrete structure of utility model is provided by Fig. 1 profile.
Below in conjunction with Fig. 1 the utility model concrete structure and using method are described.
The telfon plastic that this solder sucker lower end suction nozzle (10) adopts high temperature resistant (about 250 °) not glue tin is made, utilize the elastic properties of materials and the annular convex rib magnitude of interference and end cap (9) to connect firmly, end cap (9) and the pump housing (4) all adopt polypropylene and A, B, the injection mo(u)lding of S mixed plastic, and are connected into profile exterior feature body with spiral.A logical tin bar (8) made from the stainless steel material that does not glue tin is arranged in the interior shape lower end suction nozzle (10), it is as mold insert and use A, B, the piston rod of S injection molding (1) is solidified as a whole, the piston rod mid portion is made the piston ring shape standard " zero " RunddichtringO (5) is housed, the piston rod upper end is the square-section (also available circular metal inserts edge system) of single injection-molded, push rod was again that its side of impulse stroke control lever has two strap saw serrate slots when it was work, the stroke distances of two kinds of sizes of control piston bar has two kinds of different tin amounts of inhaling to guarantee utility model respectively.The working motion of whole solder sucker only uses a compression spring (6) as power source, control bolt (2) small pressure spring (3) the manipulation work made from the same plastics (or metal) that are contained in the square hole of the pump housing (4) upper end.In the end cap upper end pump housing (4), be with the protective cover (7) of injection molded in addition, enter in the pump housing in order to the useless tin bits that prevent to fly into.
Figure 1 shows that the profile when solder sucker is treated work, should guarantee that logical tin bar (8) lower surface to suction nozzle lower surface distance h is the 5-8 millimeter less than piston rod (1) upper surface to the pump housing (4) upper surface distance H this moment, logical tin bar can run through suction nozzle when guarantee continuing down by piston rod, realizes releasing and also reclaims the useless function that melts tin and cleaning suction nozzle inwall.
During use suction nozzle (10) is aimed at useless molten tin, press control bolt (2) the compression small pressure spring (3) that exposes outside the pump housing (4) with thumb, the zigzag groove of control bolt convex profile of tooth thrust surface and piston rod (1) side breaks away from, piston rod this moment (1) drives sealing ring (5) under compression spring (6) effect, move on logical tin bar (8) is quick, make and form negative pressure in the pump housing and the suction nozzle, thereby the useless molten tin in the printed board is sucked in the suction nozzle (10), expose from the suction nozzle aperture until logical tin bar by lower piston rod (1) then, useless molten tin is pushed in the useless tin cylinder, and solder sucker recovers diagram and treats duty.
