In execution mode and claims, unless in interior literary composition, for article, be particularly limited to some extent, " one " can make a general reference single one or more with " being somebody's turn to do ".
" approximately " used herein, " approximately " or " roughly " are to modify any quantity that can slight variations, but this slight variations can't change its essence.In execution mode, unless otherwise noted, represent that the error range of the numerical value of being modified with " approximately ", " approximately " or " roughly " is generally to allow in 20 percent, be preferably in 10, be in 5 percent more preferably.
Technical scheme of the present invention is a kind of manufacture method of LED conducting wire frame, and it can be applicable to industry manufacture, or is used in widely relevant sport technique segment.It is worth mentioning that, the manufacture method of the technical program can prevent that the situation that colloid breaks from occurring.Below collocation Fig. 2～Fig. 4 is illustrated to the embodiment of this manufacture method.
Fig. 2 is the flow chart according to the manufacture method 200 of a kind of LED conducting wire frame of one embodiment of the invention.As shown in Figure 2, manufacture method 200 comprises step 210～240(and should be appreciated that, mentioned step, except chatting especially bright its order person, all can adjust its front and back order according to actual needs in the present embodiment, even can carry out simultaneously or partly simultaneously).
First, in step 210, provide a metal substrate; In step 220, on metal substrate, form a plurality of conductor area, and expect steathily hole in the relative both sides formation two of each conductor area; In step 230, in each conductor area, form an insulation colloid; In step 240, when to each conductor area punching press, from relative two side direction two of each conductor area, expect that steathily hole pushes, to prevent that insulating cement body from breaking, and each conductor area is departed from, to obtain a plurality of finished products (that is, LED conducting wire frame) from metal substrate.
For above-mentioned steps 210～230 is done further to set forth, please refer to Fig. 3, Fig. 3 is a kind of LED conducting wire frame structure 300 according to one embodiment of the invention floor map before blanking.As shown in Figure 3, LED conducting wire frame structure 300 comprises metal substrate 310 and a plurality of insulation colloids 320.Structurally, metal substrate 310 has a plurality of conductor area 312, and the relative both sides of each conductor area 312 form two and expect steathily hole 330.A plurality of insulation colloids 320 are formed in these conductor area 312.
Particularly, hole 330 is expected in the two relative other formation two of the first side 313 of conductor area 312 steathily, and two the second relative side 314 sides of each conductor area 312 form two perforates 340, and wherein the length of the first side 313 is the length that is greater than the second side 314.
In Fig. 3, each expects that hole 330 is that a strip is expected hole steathily steathily, and strip expects that the length in hole is approximately more than or equal to the length of the first side of each conductor area steathily.Whereby, when blanking, strip expects that there are enough geometric distortions in hole steathily, to prevent that insulating cement body 320 from breaking.
In implementation, insulation colloid 320 is to be formed in each conductor area 312 with injection molding method.In an embodiment, insulation colloid 320 can be thermoplasticity colloid, thermoplasticity colloid can be via heating and melting curing molding repeatedly.For instance, thermoplastic cement style is as can be polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, polyvinyl chloride (PVC), acryl resin, Merlon (PC), fluorine-type resin or other suitable material or above-mentioned derivative or above-mentioned combination.
Or in another embodiment, insulation colloid 320 can be thermosetting colloid, thermosetting colloid is to become solid state after being heated to uniform temperature, even if continue heating, also cannot change its state.For instance, thermosetting cement style is as can be fluosite, urea resin, epoxy resin, silicone grease, melamine or other suitable material or above-mentioned derivative or above-mentioned combination.
On the other hand, for above-mentioned steps 240 is done further to set forth, please refer to Fig. 4, Fig. 4 is a kind of LED conducting wire frame structure 300 according to one embodiment of the invention floor map after blanking.As shown in Figure 4, when to conductor area (being illustrated in Fig. 3) punching press, from the relative both sides 313 of conductor area to two, expect that steathily hole 330 pushes, by expecting steathily hole 330 stress deformations, the colloid 320 that prevented from insulating breaks, and increases whereby qualification rate, improves production capacity.And conductor area after metal substrate 310 departs from, can be used as a plurality of LED conducting wire frames together with non-cracked insulation colloid.LED conducting wire frame can be used to carry light-emitting diode and is electrically connected, and this is for having and conventionally know the knowledgeable institute known techniques in this technical field, and protection range that non-the present invention wants, and in this, no longer describes in detail.
Although the present invention discloses as above with execution mode; so it is not in order to limit the present invention; anyly be familiar with this skill person; without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, so the scope that protection scope of the present invention ought define depending on appending claims is as the criterion.
