The present invention is directed to the shortcoming of the silicon rubber cup of above-mentioned existing strain finger-position rod device, improved structure and manufacture method thereof are provided.
At first, column type fiber 30 of the present invention, as Fig. 3, Fig. 4 and shown in Figure 5, its structure is except that having cylindrical body 306, the in addition additional holder section 302 in bottom, wherein this holder section 302 can be multiple different shape, for example collar plate shape, anchor type (anchor), ball-shaped, meander-like, even be zigzag or the like, this sentences collar plate shape is example.Wherein, fiber 30 is served as reasons and is had the polymeric material of hard slightly material characteristic, for example nylon (nylon) is made, and about 0.06 centimetre of its cylindrical body 306 radiuses, average length are less than 2.0 centimetres right cylinder, and 302 of holder section are the about 0.12 centimetre disc of radius.For specifically describing this kind fibre structure, below illustrate especially exemplified by three embodiment in detailed situation of the invention process.
The structure of first embodiment of the invention as shown in Figure 3, on the outside surface 18 of silicon rubber cup shape body 15, is stained with an adhesion layer 31, and this adhesion layer 31 also is stained with a plurality of outward extending fibers 30.As previously mentioned, fiber 30 has a cylindrical body 306 and a collar plate shape holder section 302, and collar plate shape holder section 302 inlay cards of fiber 30 and adhering among the adhesion layer 31.At this moment, by the inlay card effect of collar plate shape holder section 302, need not cover a protective seam again, what fiber 30 can be firm adheres in the adhesion layer 31, and is difficult for being pulled out, dropping in use.
The main manufacturing step of first embodiment is stated as follows on the way.
(1) at first with existing pressing mold manufacturing (compression molding) or injection moulding methods such as (injectionmolding), produces silicon rubber cup shape body 15.
(2) this silicon rubber cup shape body 15 is placed on the grounded metal plate in the static coating system (Electrostatic PlantingSystem), and a plurality of fibers 30 are positioned over the accumulator tank (Reservoir) of system, this static coating system can carry out the electrostatic spinning manufacturing process.
(3) outside surface at cap shape body 15 covers one deck adhesion layer 31, for example silicomethane (SilaneAdhesives), and maintenance liquid (can keep liquid with type of heating as described above).
(4) method by electrostatic spinning is spread a plurality of fibers 30 in the accumulator tank (Reservoir) and is invested on the silicon rubber cup outside surface 18.Because adhesion layer 31 still is liquid, by Electrostatic Absorption strength, in the just liquid up to one's neck in adhesion layer 31 of the holder section 302 of fiber 30.
(5) liquid adhesion layer 31 is solidified, fiber 30 just adheres to the outside surface that is secured in silicon rubber cup shape body 15.
Wherein, in the manufacture process of step (4), because these fiber 30 two ends have asymmetric structure, therefore can utilize the control method of existing electrostatic spinning, utilize fiber 30 two ends proportions different or (with) mode of operation that varies in size of static, control a plurality of fibers 30 all with certain end the preceding mode advance.This sentences holder section 302 in preceding enforcement, holder section 302 is advanced towards silicon rubber cup 15, and since in the fiber 30 with static can not run off by silicon rubber cup 15, so electrostatic repulsion will make these a plurality of fibers 30, vertically stand, extend on silicon rubber cup shape body 15 outside surfaces.
The second embodiment of the present invention on the outside surface of silicon rubber cup shape body 15, has a plurality of outward extending fibers 30 as shown in Figure 4.As previously mentioned, fiber 30 has a cylindrical body 306 and a collar plate shape holder section 302, and the collar plate shape holder section 302 of fiber 30 is embedded among silicon rubber cup shape body 15 bodies.At this moment, by the inlay card effect of collar plate shape holder section 302, need not re-use adhesion layer or cover a protective seam, fiber 30 embedding securely invests in the silicon rubber cup 15, and is difficult for being pulled out, dropping in use.
Shown in Fig. 6 A and Fig. 6 B, when second embodiment made, mold system comprised external mold 62 and internal mold 64.The inside surface of this external mold 62 is provided with a plurality of containing holes 622.The degree of depth of containing hole 622 is about 2/3rds of fiber 30 length, and its aperture is slightly larger than the line footpath of the cylindrical body 306 of fiber 30 approximately.The top of containing hole 622 also is communicated with an aperture 624, and the aperture of aperture 624 is slightly less than the line footpath of the cylindrical body 306 of fiber 30.This a plurality of apertures top is interconnected by a through hole 626, and to a vacuum system.
Second embodiment comprises following main manufacturing step.
(1), places on the grounded metal plate of electrostatic cloth phytem system, and a plurality of fibers 30 are positioned over the accumulator tank (Reservoir) of this electrostatic cloth phytem system with this external mold 62.
(2) electric discharge device with this electrostatic cloth phytem system starts, beginning electrostatic spinning manufacturing process.This moment controlling fiber 30 working direction, the end that makes holder section 302 after, so that a plurality of fibers 30 are arranged in the containing hole 622 of external mold 62.
(3) start vacuum system,, close discharge system, make not its cofibre 30 (not shown) in being arranged in containing hole 622, break away from from external mold 62 surfaces with fiber 30 absorption that are arranged in the containing hole 622.Be stiffening effect, even can be used a deionization blowning installation (DE-ionized Air blower, not shown), its cofibre 30 is blown off.
(4) implement pressing mold manufacturing or injection moulding manufacturing process, finish the making of silicon rubber cup shape body 15, so fiber 30 is exposed to the outer part of containing hole 622, comprise holder section 302, as Fig. 4, be fixed in the silicon rubber cup shape body 15.
The third embodiment of the present invention on the outside surface of silicon rubber cup shape body 15, has a plurality of outward extending fibers 30 as shown in Figure 5, and outermost layer then is stained with an adhesion layer 21.As previously mentioned, fiber 30 has a cylindrical body 306 and collar plate shape holder section 302.At this moment, the effect by collar plate shape fixator part 302 has increased adhered area, and fiber 30 just can adhere to securely, and is difficult for being pulled out, dropping in use.
The manufacturing of this embodiment comprises three key steps.
(1) uses methods such as existing pressing mold manufacturing or injection moulding, produce silicon rubber cup shape body 15.
(2) this silicon rubber cup shape body 15 is placed on the grounded metal plate in the static coating system (Electrostatic PlantingSystem), and a plurality of fibers 30 are positioned over the accumulator tank (Reservoir) of system, implement the electrostatic spinning manufacturing process.A plurality of fibers 30 in the accumulator tank (Reservoir) are spread on the outside surface that invests silicon rubber cup shape body 15.In manufacturing process, controlling fiber 30, as first embodiment, with holder section 302 the preceding mode advance.When fiber 30 touches the silicon rubber cup outside surface, because electric charge can not run off by silicon rubber cup, electrostatic repulsion will make these a plurality of fibers 30 vertically extend, and by the effect of holder section 302, and firmly stand.
(3) cover one deck liquid state again, for example the adhesion layer 21 of silicomethane (Silane Adhesives) on the outside surface of silicon rubber cup shape body 15, is finished the 3rd embodiment as Fig. 5.
Though the preferential embodiment of above combination has disclosed the present invention; yet it is not in order to limit the present invention; any personnel that are familiar with this technology; without departing from the spirit and scope of the present invention; can do some and change and retouching, so protection scope of the present invention being as the criterion of should being considered as that appended claim defines.
