Abstract

The utility model provides a window lens, which comprises a glass lens, a light stopping thin film stuck to the bottom surface of the glass lens, and a frame wrapping the periphery of the glass lens in an injection mode. The frame of the window lens is formed around the glass lens in an injection wrapping mode, so the joint strength of the frame and the glass lens is good, and the manufacturing cost of the whole window lens can be saved.

Description

Visual window lens

Technical field

The relevant a kind of visual window lens of the utility model is meant a kind of visual window lens that is surrounded by the plastic cement frame of penetrating especially.

Background technology

Along with development in science and technology and people under the high-quality demand of electronic product, the electronic product with giant-screen form become people the target of anxious pursuit.And generally be earlier visual window lens to be carried out engineerings such as application, printing at the production method of giant-screen form at present, utilizing a sticker then, for example the double faced adhesive tape of 3M is bonded together an above-mentioned visual window lens and a plastic parts through application.But utilize the prepared giant-screen form of this kind bonding mode, often, cause visual window lens and plastic parts to be easy to separate because bond strength is not enough.Moreover, have a lot of detailed problems when bonding, for example the surface cleanliness of adhesive surface, temperature, exert pressure etc. and need consider.

In view of this, the utility model is satisfied the disappearance at above-mentioned known technology, proposes a kind of brand-new visual window lens, effectively to overcome these above-mentioned problems.

Summary of the invention

Fundamental purpose of the present utility model is providing a kind of visual window lens, and its frame is to penetrate wrap molding around glass mirror, so the bond strength of frame and glass mirror is good and the cost of manufacture that can save the Integrated visual window eyeglass.

Another purpose of the present utility model is providing a kind of visual window lens, and it adopts the frame mode of penetrating wrap molding, can realize the diversity of products appearance.

In order to achieve the above object, the utility model proposes a kind of visual window lens, it includes a glass mirror; One is attached at the resistance optical thin film on the glass mirror bottom surface; And one penetrate the frame that is wrapped in around the glass mirror.

The useful technique effect that the utility model reaches is: the good and cost of manufacture that can save the Integrated visual window eyeglass of the bond strength of frame and glass mirror.

Now for making the auditor further understanding and understanding more be arranged to architectural feature of the present utility model and the effect reached, sincerely help with preferred embodiment figure and cooperate detailed explanation, illustrate as afterwards:

Description of reference numerals

10 visual window lens; 12 glass mirror; 14 resistance optical thin films; 16 frames; 18 pilot holes; 20 master toolings; 22 projections; 24 die cavitys.

Embodiment

At first, see also Fig. 1, Fig. 2 and Fig. 3, it respectively is the cut-open view of AA line segment of embodiment front perspective view, rear perspective view and Fig. 2 of visual window lens of the present utility model.As shown in the figure, visual window lens 10 of the present utility model consists predominantly of a glass mirror 12, its bottom surface be sticked one the resistance optical thin film 14; And one penetrate the frame 16 that is wrapped in around the glass mirror 12, and the material of this frame 16 is a plastic cement.

The material of above-mentioned resistance optical thin film 14 can be polybutylene terephthalate (PBT).In addition, more be provided with at least one pilot hole 18 on the glass mirror 12, for when penetrating the frame 16 of plastic glue, glass mirror 12 being positioned.

Continue, at the manufacturing process proposition related description of visual window lens 10 of the present utility model.See also Fig. 4 (a)～4 (b).At first, shown in Fig. 4 (a), provide a glass mirror 12 and a resistance optical thin film 14, this glass mirror 12 can be the glass mirror through cure process, utilizes Filming Technology will hinder optical thin film 14 subsequently and is attached on glass mirror 12 bottom surfaces.Continue, a retable rubber moulding tool is provided, it can include a public plastic mould and a female plastic mould, the glass mirror 12 that posts is put into the die cavity 24 of master tooling 20, shown in Fig. 4 (b).At this moment, for making glass mirror 12 good location in die cavity 24, can in die cavity 24, be provided with projection, shown in Fig. 4 (c) corresponding to pilot hole 18, utilize protruding 22 pilot holes 18 that are inserted on the glass mirror 12 of determining, with glass mirror 12 good location in die cavity 24.Subsequently, cover the male mould (not shown), carry out the plastic rubber material injection, around glass mirror 12, penetrate the frame 16 that bag forms a plastic cement to utilize one-body molded mode.At last, after injection was finished, goods were taken out in die sinking, can obtain visual window lens of the present utility model as shown in Figure 1.

In sum, the utility model provides a kind of brand-new visual window lens, it is to utilize the mode of penetrating wrap molding directly to form the plastic cement frame around the glass mirror that is fitted with the resistance optical thin film, realize that thus glass mirror engages one-time formed purpose with the plastic cement frame, also realizes the diversity of products appearance.

Moreover visual window lens of the present utility model does not have the use sticker, therefore can avoid many engagement problems of known use sticker, has promoted the bond strength of glass mirror and plastic cement frame simultaneously yet.In addition, the utility model saves the operation of adhesion, and the cost that this operation increased, and then reaches cost-effective purpose.

More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and the spirit and the interior of scope that limit in claim can carry out many modifications, variation or equivalence to it, but they all will fall in the protection domain of the present utility model.
