Embodiment
The manufacture method of disposable microphone cover provided in the present embodiment, the disposable microphone cover of its manufacturing as shown in Figure 3 and Figure 4, whole microphone cover when non-working condition just as the pocket of U-shaped, promptly in the middle of the sponge block of U-shaped, offer the opening that corresponding cut surface takes the shape of the letter U, make its everywhere thickness be 3 millimeters, so its shape and existing disposable microphone cover after strutting is similar, also can entangle the microphone head preferably.
Its manufacture process comprise get the raw materials ready, otch, three steps of tip relief, specifically describe as follows:
At first get the raw materials ready: will be used to make the material of disposable microphone cover, and be generally sponge, 75 millimeters of cut growths, wide 80 millimeters, thick 15 millimeters flat block blank.So-called flat bulk is meant in the three-dimensional dimension of square has the size of one dimension to be significantly less than other bidimensional.Thickness such as this place blank is 15 millimeters, only is about 1/5th of its length and width.Blank dimension is determined by following: its length is got 75 millimeters herein with of the prior art identical, mainly in order to have guaranteed certain depth, can be loaded into the microphone head.The twice of blank width should be slightly larger than the circumference of microphone head, if the diameter of existing microphone head is 50 millimeters, the width of blank is got 80 millimeters and is advisable so, in fact because material has very big elasticity, a little bit smallerly also can overlap to such an extent that enter.The thickness that loses when the twice that blank thickness is generally microphone cover thickness is added otch, the difference of looking material and technology is generally at 4 millimeters to 20 millimeters, preferably at 8 millimeters to 15 millimeters.Most preferably in the size, microphone cover thickness is generally 5 millimeters, because otch will lose 5 millimeters, is advisable so the thickness of blank is got 15 millimeters.
Otch then: use interior cutter sweep shown in Figure 5, the center, a side from blank cuts out a Tiaokou in blank, takes the shape of the letter U through the cut surface of cutting.The U-shaped otch is by a rectangle and semi-circular combining, and two limits of semicircular circular arc and rectangle promptly constitute U-shaped, and wherein rectangle part is wide 70 millimeters, dark 30 millimeters, and the diameter of semi-circular portion is 70 millimeters, and the thickness of mouth is 5 millimeters.Interior cutter sweep comprises: binding post 1, sheet metal 2 and otch heating wire 3.Otch heating wire 3 is connected between two binding posts 1, and after to two binding posts 1 energising, otch heating wire 3 will red heat, can cut blank.Otch heating wire 3 comprises the extension 31 of semicircular cutting part 32 and two sections linearities, and the distance between two extensions 31 is less than the diameter of cutting part 32, so that extension 31 is unlikely blank is carried out unnecessary cutting, and produces waste product.
In order to guarantee that further extension 31 is unlikely blank is carried out unnecessary cutting, each extension 31 is provided with sheet metal 2, and keeps sheet metal 2 reliably to contact with extension 31.Because sheet metal 2 has bigger cross-sectional area, its resistance is less, be equivalent to extension 31 and sheet metal 2 parallel connections herein, thereby all-in resistance is little, the voltage of getting is just very little, make the electrical power of the overwhelming majority all consume, so extension 31 heatings are little, temperature is low, can not produce cutting blank at cutting part 32.In fact because sheet metal 2 has bigger area of dissipation, further reduced the temperature of extension 31.
Last tip relief: as shown in Figure 6 and Figure 7, use the tip relief device that blank is carried out tip relief, remove the unwanted material of blank outer rim.Fig. 6 is the view of cut direction, and Fig. 7 is perpendicular to the view of cut direction.The tip relief device comprises cutter unit and feed unit.Cutter unit comprises semicircular tip relief heating wire 5, and its two ends also are connected to binding post 1.After binding post 1 energising, tip relief heating wire 5 red heat are with the excess stock excision of blank outer rim.Feed unit comprises the mould 4 that is used for fixing blank, and the U-shaped kerf of this mould 4 and blank is similar and size is bigger, with guarantee blank be enclosed within on this mould 4 after unlikely too pine and influence follow-up operation.
Elder generation's power-on makes tip relief heating wire 5 red heat during use, makes mould 4 moving linearlies that package blank then, at the straight flange excision excess stock of blank one side.Straight flange makes after cutting mould 4 around the center of circle of its end semicircle Rotate 180 °, to cut out the semi-circular top of U-shaped microphone cover.Make mould 4 continue rectilinear motion at last again,, so far promptly finished the making of a microphone to cut out other one side of U-shaped microphone cover.
Need to prove that the size of blank is except relevant with the size of microphone head, and is also relevant with the specification of selected sponge.Can be a little thin for the sponge that density is higher the microphone interplanting, the size of blank just should be accordingly more greatly; If the density of the sponge of being adopted is lower, then need the microphone interplanting thicklyer, the size of blank just should be accordingly more greatly.
The present invention takes the method for otch to form the cavity that holds the microphone head, thereby waste material is few.Because employed material has very big elasticity, thereby the U-shaped otch that is cut out can well be enclosed within on the microphone head after strutting, and the product that its result of use is produced unlike prior art is poor.The needed flat block blank of technical scheme of the present invention, its volume only be in the prior art square shape blank 48%, thereby greatly reduce cost of material, also meet the social morals of current environmental protection and energy saving.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
