Abstract
The scour-type tin-lining device of the utility model is used for tin lining, comprising a tin pump, a constant temperature tin groove and a control portion. The utility model is characterized in that 1, when conducting tin lining, the surface of the tin liquid can be protected by antioxidant, not only the oxidation is reduced but also the work piece is not polluted and the tin and lead material is saved, 2, the tin liquid melts for a long time and the oxidation is little to guarantee the normal proportion of the tin and the lead, 3, the flowing tin liquid can flush off the residual assistant welding agent on the work piece to eliminate the hidden danger of corrosion.
Description
The utility model name be called wash away the type enamelling tin apparatus, be a kind of tin equipment of warding off, can be used for the tin of warding off on electronic devices and components, accessory, the lead-in wire (pin).
In electronic product is produced, the solderability of component down-lead (pin) is very important, improve the assembly welding quality of electronic product, just require the lead-in wire (pin) of components and parts that good solderability is arranged, so the tin quality of warding off of lead-in wire (pin) just becomes the key that improves electronic product assembling welding quality.
The existing tin technology of warding off is that lead-in wire (pin) is immersed wicking in the static soldering tin, this method tin liquor surface oxidation is serious, influenced and warded off the tin quality, and waste tin lead material, in order to improve the tin technology of warding off, improve the solderability of electronic devices and components, the applicant has proposed to wash away new departure of warding off tin, and the utility model of having used this conceptual design.
One, existing problem of warding off the existence of tin technology:
1. prior art is to ward off with the tin liquor drill traverse, and this method can not prevent the tin liquor oxidation, so cause the waste of tin lead material.
2. tin liquor can not flow in the prior art tin liquor groove, can't produce the scouring force to workpiece, can not effectively remove residual sticking scaling powder on the workpiece, so caused corrosion hidden danger, can not in time make the abundant wetting affinity of tin liquor, produce pin hole, interlayer, influence and warded off the tin quality so ward off Xi Shiyi.
3. the prior art tin liquor is when fusion for a long time, and the lead metal oxidation is serious, and the oxidation lead skim strikes off a lot, thereby changed the normal ratio of tin lead content in the tin liquor, because the change of tin lead proportion is affected the weld strength of tin liquor and wettability, has reduced the welding affinity.
4. how variant have the temperature of warding off tin equipment tin liquor top layer and deep now, can not control temperature in minimum zone effectively.
5. existing ward off tin equipment tin liquor surface and can't use antioxidant, if put into antioxidant then when warding off tin antioxidant stain workpiece.
6. prior art need often scrape off the lead oxide dregs on tin liquor surface when warding off workpiece with the tin liquor drill traverse, influences production efficiency, also wastes the tin lead material.
7. though prior art can be carried out ultrasonic wave and warded off tin, can not solve the problem of the anti-oxidation of tin-lead solder, so tin plumbous waste bigger, moreover ultrasonic wave is warded off tin device structure complexity, creating conditions, it is high to require, and work noise is big, is not suitable for doing in streamline the corollary equipment that small workpiece is warded off tin.
In view of the problem of above existence, in order to improve the tin technology of warding off, improve and ward off the tin quality, save the tin lead material, designed the utility model.
Two, structure of the present utility model and operation principle:
The utility model is made up of tin liquor pump and constant temperature tin liquor groove two parts.Tin liquor pump such as elbow tobacco pipe shape are made up of pump case, pump shaft, pump impeller and motor.The tin liquor pump is contained in tin liquor groove middle part, is immersed in the tin liquor, and tin liquor pump flow jeting port up is in tin liquor groove central authorities, exceeds the tin liquor groove slightly.
During work, energising heating earlier, treat that the tin-lead solder fusion is tin liquor after, start the tin liquor pump flow jeting port of tin liquor in the tin liquor groove from the tin liquor pump extruded, tin liquor flow back into again in the tin liquor groove and extrudes from flow jeting port through the tin liquor pump more then, and tin liquor pumps through the circulation of tin liquor pump like this.
Only need when warding off the tin operation workpiece is immersed in the tin liquor pump flow jeting port, wash away workpiece by the tin liquor of jet flow and ward off tin.
Because the surface of tin liquor is lower than the flow jeting port of tin liquor pump in the tin liquor groove, thus can in the tin liquor groove, put antioxidant, after the antioxidant fusing, cover the surface of tin liquor in the tin liquor groove, tin liquor and air are separated, prevented the tin liquor oxidation, can not stain workpiece again.
Three, substantive features:
1. the utility model is to wash away surface of the work by the tin liquor that circulates, and it has removes residual sticking scaling powder, the effect of in time wetting, affinity workpiece.So can obtain be difficult for forming the matter of pin hole, interlayer close, bright ward off the tin layer.
2. the tin liquor of the flow jeting port of the utility model tin liquor pump extrusion contacts with air, and all the other tin liquors have antioxidant to cover in the tin liquor groove, so oxidation is very little, have saved the tin lead material.
3. because the tin liquor oxidation is very little,, when warding off the tin operation for a long time, can guarantee that the tin lead metal content ratio of fusion is normal so the lead metal oxidation is little.
4. tin liquor circulates, so the top layer is consistent with the temperature in deep.
5. the flow jeting port of tin liquor pump can and be warded off the tin requirement and manufacture by the workpiece shape, and the control flow jeting port makes the tin liquor oxidation at bottom line at minimum usable floor area.
6. owing to tin liquor circulation jet flow, so tin liquor surface oxide-free need not to strike off oxidizing slag so ward off when tin is operated.
7. the utility model simple structure, volume are little, easy to operate, are suitable for the supporting use of streamline, and be with practical value.
8. the utility model simple structure is easy to manufacture, produces early than tissue.
Claims (1)
- The utility model has adopted the tin pump to combine with the new structure of molten tin bath, it is characterized in that: tin liquor pump such as elbow tobacco pipe shape are immersed in the tin liquor, and the flow jeting port of pump exceeds the tin liquor surface slightly, so the available antioxidant protection in tin liquor surface.The flow jeting port place does not have antioxidant, so do not stain workpiece when warding off tin, the structure that this kind tin pump and molten tin bath combine is the feature of this enamelling tin apparatus.
