Fig. 3 to Fig. 4 is for manufacturing the schematic diagram of the main flow process of optical mirror slip.
Embodiment
Please refer to the drawing 1 is with shown in Fig. 2, and the optical mirror slip 10 of the utility model preferred embodiment is to make with glass, and has one first minute surface 11 and one second minute surface 12 that is positioned at opposed surface.And the Main Differences of the utility model and prior art, be that this optical mirror slip 10 is on the surface of these the first minute surface 11 place sides, there is one first reference field 13 and the locating surface 14 that around this first minute surface, arrange, and this first locating surface 14 is inclined-planes, and this first reference field 13 this locating surface 14 approach this first minute surface 11, the order that this optical mirror slip 10 is connected from inside to outside in the surface of these the first minute surface 11 place sides is sequentially this first minute surface 11, this first reference field 13 and this locating surface 14.
And the function of this locating surface 14 and this first reference field 13, mainly when assembling, use for one first location thing (as eyeglass, figure do not show) directly connect to, with by this first reference field 13 directly connect to, reach the effect of fixing the relative axial position between this first minute surface 11 and this first location thing, simultaneously by this locating surface 14 directly connect to, reach and fix this first minute surface 11 and this first object of locating the radially relative position between thing.In addition, between this first reference field 13 and this locating surface 14, be formed with an angle, and this angle is an obtuse angle, and by the design at this obtuse angle, just can guarantees this locating surface 14 and this first reference field 13 and this first fixed effect of locating between thing.
Except above-mentioned technical characterictic, this optical mirror slip 10 is on the surface of these the second minute surface 12 place sides, also there is one second reference field 15 arranging around this second minute surface 12, in order to when assembling for and one second location thing (as eyeglass or pad, figure does not show) connect to, to fix this second minute surface 12 and this second relative axial position of locating between thing.It is worth mentioning that, between this second reference field 15 and this first reference field 13, be to be the design being parallel to each other, and by this design, just can effectively reduce after this first location thing and this second location thing and 10 assemblings of this optical lens the error of the relative axial position between this first location thing and this second location thing.
Thus, utilize the structural design of this above-mentioned first reference field 13, this locating surface 14 and this second reference field 15, just can be really and fix reliably between this optical mirror slip 10 and other location things (as other eyeglass or pad etc.) in axially and the relative position that makes progress of footpath, and can not be subject to the impact of lens barrel or other assembling things, and can guarantee the optical performance after 10 assemblings of this optical mirror slip, can be effectively and positively approach default perfect condition.
In addition, refer to Fig. 3 to Fig. 4, the manufacture method of this above-mentioned optical mirror slip 10 is as follows:
As shown in Figure 3, first obtain one first mould 100 and one second mould 200, and on this first mould 100, there is one first die 110, and on this second mould 200, there is one second die 210, and this second die 210 is over against this first die 110.
Then, a uncured frit 300 is set on this first die 110, and make this frit 300 between this first die 110 and one second die 210, and mobile this second mould 200, make to produce displacement close to each other between this first mould 100 and one second mould 200, but between this first mould 100 and one second mould 200, there is an interval D and be not in contact with one another and be an open space.Certainly, on reality is implemented, also removable the first mould 100 or mobile this first mould 100 reaches identical effect with this second mould 200 simultaneously.
Afterwards, as shown in Figure 4, this second die 210 is pressed against on this frit 300, make this frit 300 towards the surface of this first die 110, form to should first mirror face 11, the shape of the first reference field 13 and this locating surface 14, and towards the surface of this second die 210, form to should second the shape of minute surface 12 and this second reference field 15, and this frit 300 pressurizeds and overflow the position 310 in region between this first die 110 and this second die 210 outward, in the interval D between this first mould 100 and one second mould 200.
Finally, solidify this frit 300 mobile this second mould 200, the surface that this frit 300 is contacted with this first die 110 forms this first minute surface 11, this locating surface 14 and the first reference field 13, and the surface contacting with this second die 210 forms this second minute surface 12 and this second reference field 15, and make between this first mould 100 and one second mould 200 to produce mutually away from displacement, to obtain as this optical mirror slip 10 of Fig. 1 and Fig. 2 institute formula, and original frit 300 is positioned at the part 310 of this interval D, can form the protruding wall 16 that the outer peripheral edges around this optical mirror slip 10 arrange, in more detail, this first reference field 13 and this locating surface 14 will be between this first minute surface 11 and this protruding walls 16, this second reference field 15 is between this second minute surface 12 and this protruding wall 16.
In addition, during due to this optical mirror slip 10 assembling, this optical mirror slip 10 can't directly contact with lens barrel (not shown), but the structure of utilizing this first reference field 13, this locating surface 14 and this second reference field 15 fixes the relative position between this optical mirror slip 10 and other location things (as other eyeglass or pad etc.), and make the structure of this protruding wall 16 can't cause the skew of the optical centre of this optical mirror slip 10.
Thus, the shape of this protruding wall 16 does not need to make to shape that should lens barrel inner structure, and after this optical mirror slip 10 is made, do not need this protruding wall 16 polish again or cut corresponding secondary processing, and can promote significantly the manufacture efficiency of this optical mirror slip 10.
In sum, this optical mirror slip 10 of the present utility model, the position in the time of not only can guaranteeing the assembling of this optical mirror slip 10 approaches desirable, more can effectively promote the manufacture efficiency of this optical mirror slip 10, and then reaches the bonus effect of saving manpower and cost.In addition, the foregoing is only the better possible embodiments of the utility model, the equivalence that every application the utility model instructions and claim are done changes, and ought to be included within the scope of claim of the present utility model.
