The sealing structure has the advantages of no bubbles, good sealing property and high manufacturing efficiency; and the problem of bubbles produced during sealing of the variable-focus liquid lens can be solved well.
Description
Technical field:
The utility model relates to a kind of optical lens, relates in particular to a kind of hermetically-sealed construction of novel liquid zoom lens.
Background technology:
In the contemporary optics zoom system, pancreatic system, more and more be subject to people's attention with its outstanding performance based on the liquid zoom lens of the wet effect of electricity.Thisly change liquid surface curvature by impressed voltage and realize that lens non mechanical movable, the compact conformation of zoom is small and exquisite, price is low, response speed is fast, power consumption is little, the life-span is long, good imaging quality, have broad application prospects.
Liquid zoom lens is to inject two kinds of mutual exclusive liquid in the metallic cylindrical tube of a hollow, and a kind of is iknsulating liquid, and a kind of is conductivity water solution, all is coated with one deck drain insulating layer on the metallic cylindrical tube inside and outside wall.In existing liquid zoom lens, structurally all be to adopt the structure of a kind of similar " sandwich " that the liquid in the cylindrical tube is sealed mostly, the i.e. structure of " clear glass+liquid lens main body+transparency electrode ", by from lens outer wall and transparency electrode extraction electrode so that apply voltage to conducting liquid.When making liquid zoom lens, with the end sealing of transparency electrode, from the other end perfusion conducting liquid and the iknsulating liquid of cylindrical tube, with a transparent glass sheet cylindrical tube is sealed at last then earlier cylindrical tube.Yet the technique effect of this structure is unsatisfactory, because sneak into some air through regular meeting in the process of sealing, causes the inside of liquid zoom lens to have minute bubbles, thereby influences the effect of lens, the failure that this will finally cause liquid zoom lens to be made.
The utility model content:
Technical problem to be solved in the utility model is the deficiency that overcomes the prior art hermetically-sealed construction, a kind of hermetically-sealed construction of liquid zoom lens is provided, adopt two kinds of different crown caps that the two ends of cylindrical tube are sealed, both be convenient to inject the liquid of lens body, can fully seal again, not produce bubble.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of hermetically-sealed construction of liquid zoom lens, comprise the cylindrical tube of hollow and be contained in intraluminal mutual exclusive iknsulating liquid of this cylindrical tube and conducting liquid, it is characterized in that: the sealing structure also includes mesoporous metal lid and atresia crown cap, described porose crown cap is fixed on an end of described cylindrical tube hermetically, the center of this porose crown cap is provided with a transparent glass sheet, the both sides of this transparent glass sheet respectively offer a through hole respectively, described atresia crown cap is fixed on the other end of described cylindrical tube hermetically and contacts with conducting liquid in the cylindrical tube, and the center of this atresia crown cap is provided with a transparent glass sheet.
The through hole of the hermetically-sealed construction of liquid zoom lens described in the utility model is a stepped hole, and its outside is a large diameter hole, and the inboard is a small diameter bore; Described porose crown cap and atresia crown cap are made by copper product, lead to electrode on this cylindrical tube outer wall and the atresia crown cap.
Different with the structure of traditional liquid zoom lens, the utility model adopts two kinds of crown caps to replace clear glass and transparency electrode respectively, under the situation that two crown caps have sealed cylindrical tube, in the cylindrical tube tube chamber, inject the liquid of lens body by the small through hole on the crown cap, therefore avoid air to sneak into the possibility of lens liquid thereby reached, the utlity model has no bubble, good airproof performance, advantage that make efficiency is high.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment:
Now with accompanying drawing the utility model is done an explanation in conjunction with specific embodiments.
At first see also Fig. 1 structural representation of the present utility model, the hermetically-sealed construction of diagram liquid zoom lens comprises cylindrical tube 1, porose crown cap 2, the atresia crown cap 7 of hollow and is contained in this cylindrical tube 1 intraluminal mutual exclusive iknsulating liquid 5 and conducting liquid 6.All be coated with one deck drain insulating layer on the inside and outside wall of described cylindrical tube 1, described porose crown cap 1 is adhesively fixed on an end (being the upper end among the figure) of described cylindrical tube 1 hermetically, see also Fig. 2 again, the center of this porose crown cap 2 is provided with a transparent glass sheet 4 as clear aperture, the both sides of this transparent glass sheet 4 respectively offer a through hole 3 respectively, this through hole 3 is a stepped hole, its (being the upper end among the figure) towards cylindrical tube 1 outside is a large diameter hole, and the aperture is identical with the diameter of the syringe needle that injects iknsulating liquid 5 and conducting liquid 6 usefulness, its (being the lower end among the figure) towards cylindrical tube 1 inboard is a small diameter bore, and the aperture is less than the diameter of this syringe needle.Described atresia crown cap 7 is adhesively fixed on the other end (being the lower end among the figure) of described cylindrical tube 1 hermetically, and the center of this atresia crown cap 7 is provided with a transparent glass sheet 4 equally as clear aperture.Iknsulating liquid 5 and conducting liquid 6 are in the top and the bottom of cylindrical tube 1 tube chamber respectively in described cylindrical tube 1 tube chamber, thereby atresia crown cap 7 and cylindrical tube 1 interior conducting liquid 6 contacts, and porose crown cap 2 contacts with iknsulating liquid 5.Drain insulating layer on cylindrical tube 1 outer wall is scratched, respectively from cylindrical tube 1 outer wall scratch and atresia crown cap 7 on extraction electrode 9 and 8 (see figure 1)s, thereby can apply voltage U to conducting liquid 6.Described porose crown cap 2 and atresia crown cap 7 are made by copper product, and also available other excellent conductive material is made, and it can make the lid shape that has the outer, with can be involutory with cylindrical tube 1 sealing.
The utility model when making, earlier with epoxy glue with atresia crown cap 7 and cylindrical tube 1 adhering and sealing, again with porose crown cap 2 and cylindrical tube 1 adhering and sealing; Then a through hole 3 of aiming on the porose crown cap 2 with syringe successively injects conducting liquid 6 and iknsulating liquid 5 in cylindrical tube 1, when perfusion fluid, because the internal diameter of through hole 3 bottoms is less than the diameter of syringe needle, so the syringe needle of syringe can not be deep into lens inside, and another through hole 3 plays the effect of discharging air, in order to avoid form bubble in liquid; After at last in liquid injects cylindrical tube 1 fully, with two through hole 3 sealings.
The hermetically-sealed construction of liquid zoom lens described in the utility model has no bubble, good airproof performance, advantage that make efficiency is high, produces the problem of bubble when can be good at solving the liquid zoom lens sealing.
