Embodiment
See also Fig. 1, Fig. 2 and Fig. 3, the utility model provides a kind of double-screw bolt assembling structure of electronic package machine plate, especially finger double-screw bolt 1 assembled group that will be provided with screw is stood on the motherboard 2, object can be so as to isolated with motherboard 2 and fix and combine with screw, wherein relatively to make top another electronic installation or circuit board etc.:
Be provided with a screw that does not run through 10 in this double-screw bolt 1, this double-screw bolt 1 is the cylinder of right cylinder or other profile, and its profile and size are not limited, and can do different variations according to need.This double-screw bolt 1 outer rim lower end is equipped with a bite 11, and this bite 11 is to utilize annular knurl or embossing mode to constitute, can be in order to combine with tin cream 21, make being connected on the motherboard 2 that double-screw bolt 1 more can be firm, and effectively increase the pull-out capacity and the torsion of double-screw bolt 1 welding.
This double-screw bolt 1 can be organized and stand on each default Copper Foil 20 of motherboard 2 surface, and on the above-mentioned Copper Foil 20 and be attached with tin cream 21, is convenient to this double-screw bolt 1 was carried out the tin stove together with motherboard 2, utilizes tin cream 21 welding to be fixedly connected on the motherboard 2 double-screw bolt 1.
Be equipped with an inclined-plane 12 and form the less neck of an external diameter 13 in this place, double-screw bolt 1 outer rim bite 11 tops in addition, be easy to " climbing tin " to the seam of neck 13 places formation to make things convenient for the tin cream 21 on the motherboard 2, to increase the pull-out capacity and the torsion of double-screw bolt 1 welding.Form the double-screw bolt assembling structure of electronic package machine plate of the present utility model by above-mentioned composition.
In addition, owing to combine with motherboard 2 isolation for adapting to different objects, so the construction profile and the size of each double-screw bolt 1 also has multiple different variation (as Fig. 4) on the motherboard 2.
This double-screw bolt 1 also can supply surface mounting technique (Surface Mount Technology, SMT) the robotization facility are searched and are organized in the vacuum suction mode and stand on the motherboard 2, as shown in Figure 5, this double-screw bolt 1 can be further combined with a quick dismountable cover 3, this quick dismountable cover 3 is made with rubber-like metal lamellar body, it has a cover plate 30 in screw 10 apertures that can hide this double-screw bolt 1, and locates in the middle of these cover plate 30 inner near to be extended with three elastic clips 31 towards screw 10 directions of this double-screw bolt 1.Before this double-screw bolt 1 is assemblied in motherboard 2, can earlier this quick dismountable cover 3 be pressed together on this double-screw bolt 1, the cover plate 30 of this quick dismountable cover 3 can be pasted cover on double-screw bolt 1 and seal this screw 10, the elastic clip 31 of this quick dismountable cover 3 then embedding is sandwiched in the screw 10 of this double-screw bolt 1, makes this quick dismountable cover 3 can be so as to temporarily being combined on this double-screw bolt 1.
So should can hold cover plate 30 in the vacuum suction mode for SMT robotization facility with the double-screw bolt 1 of quick dismountable cover 3, and can in the lump double-screw bolt 1 be searched, to the location, directly place on the tin cream 21 of motherboard 2, discharged again and finished assembling work, therefore whole assembling operation will very fast, precisely and firmly be greatly improved assembly working efficient and be beneficial to volume production.
On the other hand, when carrying out soldering operation that SMT crosses the tin stove, motherboard can't influence the physical characteristics of this quick dismountable cover 3 and the steadiness of embedding folder, and behind the SMT, only need utilize suitable instrument to dial this cover plate 30 and these quick dismountable cover 3 whole pulling out fast can be replied this double-screw bolt 1 original state, isolate in order to screw afterwards can screw togather work and reach relative object with it in conjunction with motherboard.
As shown in Figure 6, this quick dismountable cover 3 also can Polyvinylchloride (PVC) or tygon resistant to elevated temperatures materials such as (PE) make, it is the thin slice body, this quick dismountable cover 3 can hot melt or dismountable mode such as gluing be fitted on the double-screw bolt 1, this quick dismountable cover 3 can hide screw 10 apertures of this double-screw bolt 1, so, before double-screw bolt 1 is assemblied in motherboard 2, can earlier quick dismountable cover 3 be fitted on the double-screw bolt 1, make this quick dismountable cover 3 can seal screw 10 and temporarily be combined on the double-screw bolt 1.So should can hold and can in the lump double-screw bolt 1 be searched in the vacuum suction mode, directly place to the location to be discharged again on the tin cream 21 of motherboard 2 and finish assembling work for SMT robotization facility with the double-screw bolt 1 of quick dismountable cover 3.
As shown in Figure 7, be extended with elastic clip 31 towards double-screw bolt 1 around the cover plate of this quick dismountable cover 3 30, but these elastic clip 31 embeddings are sandwiched in this double-screw bolt 1 outer wall, make this quick dismountable cover 3 can be so as to temporarily being combined on this double-screw bolt 1.So should can hold cover plate 30 in the vacuum suction mode for SMT robotization facility, and can in the lump double-screw bolt 1 be searched, to the location, directly place on the tin cream 21 of motherboard 2, and be discharged again and finish assembling work with the double-screw bolt 1 of quick dismountable cover 3.
Double-screw bolt 1 of the present utility model is fixed on the motherboard 2 with welding manner, therefore do not need on motherboard 2, pilot hole to be set, therefore can not have influence on the setting of circuit layout on the motherboard 2, and be convenient to the layout of circuit layout on the motherboard, can increase the design convenience, and cost is effectively reduced, and can increase the space utilization rate.
The above only is a preferable possible embodiments of the present utility model, and is non-so limit claim of the present utility model, so the equivalent structure that all utilization the utility model instructionss and accompanying drawing content are carried out changes, in like manner all is contained in the scope of the present utility model.
