Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
In order to more succinct explanation the present embodiment, at accompanying drawing or in illustrating, the known but parts incoherent with the main contents of this patent of some the art those of ordinary skill can be omitted.In addition, in order to interpreting blueprints of being more convenient for, in accompanying drawing, some parts has amplification, reduces and part omission, but does not represent size or the entire infrastructure of actual product; When not affecting interpreting blueprints and can not producing ambiguity, some parts may not chart by National Standard of Mechanical Drawing.
Embodiment.
As depicted in figs. 1 and 2, a kind of wiring board welding localization tool, comprise chassis, chassis is rectangle, and chassis comprises alignment layers 11 fixed with each other and backplane level 12; Alignment layers 11 is above backplane level 12, and alignment layers 11 has default one-tenth-value thickness 1/10; Alignment layers 11 is provided with multiple locating hole group 2, and locating hole group 2 comprises multiple positioning through hole 21; Positioning through hole 21 matches with the profile of the electronic devices and components 4 in wiring board 3, and electronic devices and components 4 can be fixed in positioning through hole 21, and the pin of electronic devices and components 4 is upward, and perpendicular to the upper surface on chassis; The positioning through hole 21 of multiple locating hole group can be identical, also can not be identical.
Above-mentioned electronic devices and components 4, namely will weld small electronic devices and components in the circuit board, for convenience, hereinafter referred to as element.
Chassis is divided into two-layer, on the one hand in order to not lesion element is (if all adopt plastics, then relatively lighter, also easily damage, all adopt steel, then than being easier to lesion element), on the other hand, be for the ease of processing, be divided into two-layer, then the alignment layers of top just only processes through hole, without processing blind hole.
Positioning through hole 21 matches with the profile of the element in wiring board, namely element can be located, inactive all around, the cross sectional shape of particular hole can be that (in diagram is circular port and cruciform vent for circle, rectangle or other shape, only for example), as long as can locate.
In Fig. 1 shown in the upper right corner is that a wiring board tips upside down on chassis, and element all below, be can't see, and can, it is seen that the pin of element, be alternatively solder joint 31.
The positioning through hole 21 of multiple locating hole group can be identical, also can not be identical, (be exactly that a locating hole group has multiple positioning through hole if identical, the quantity of positioning through hole, type, size, mutual spacing are all identical), exactly a chassis can be placed simultaneously the duplicate wiring board of multiple specification (carrying out welding the work of small element), welding efficiency is very high.Also can be a wiring board chassis being placed different size, be applicable to the little wiring board of batch (what illustrate in figure is the situation that the positioning through hole of locating hole group is all identical).
Wherein, the suitable for reading of positioning through hole is provided with chamfering or rounding (not shown).So both easily put element (having guide function), and be also not easy lesion element, after chamfering or rounding, sharp edge just eliminates.
Wherein, the material of alignment layers 11 is polytetrafluoroethylene (PTFE).Polytetrafluoroethylene (PTFE), be commonly called as " King ", intensity is high, than general plastic wear-resisting, but smooth surface, frictional force is little, is not easy lesion element.
Wherein, the material of backplane level 12 is stainless steel.Stainless intensity is high, anti-corrosion, is good baseboard material (the stainless concrete trade mark is SUS304, and this is that in stainless steel, intensity is higher, anti-corrosion capability is a kind of preferably).
Wherein, alignment layers 11 and backplane level 12 are fixed together by screw (not shown).Like this, if alignment layers 11 has worn and torn, rear replacing alignment layers 11 can be dismantled, need not wholely scrap together.
Pass through above-described embodiment, a kind of wiring board welding localization tool of the present utility model, the chassis of a rectangle arranges the locating hole of the small electronic devices and components (abbreviation element) on terminated line plate, such elder generation is placed on element in locating hole, pin upward, again wiring board back-off on chassis, the pin of element stretches into wiring board, in such welding process, position of components is stablized, solder joint is also desirable, operating personnel also facilitate, and in order to not lesion element, chassis is divided into two-layer, the employing polytetrafluoroethylene (PTFE) processing that top contacts with element, below adopts stainless steel (having certain weight and intensity) processing, processing is also convenient, and (locating hole is through hole, and without processing blind hole).Its beneficial effect is: handled easily personnel can weld this small electronic devices and components, welding position is stable, solder joint is good.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
