Abstract
The utility model discloses a OCA membrane with heavy membrane marking off mark, including heavy membrane, OCA glue film (2) and the light film who stacks gradually, its characterized in that, heavy epimembranal have at least one transversely straight nematoid marking off mark (3). The marking off mark be 2, 2 marking off mark parallel arrangement. The OCA glue film is square glue film, heavyly epimembranal is equipped with 4 alignment mark (5), 4 individual alignment mark is located the regional outside in 4 bights of OCA glue film respectively, and the alignment mark is L shape. This OCA membrane with heavy membrane marking off mark simple structure, the weight membrane is convenient for distinguish by easy to carry out.
Description
Technical field
The utility model relates to a kind of OCA film with heavy film marking.
Background technology
OCA optical cement: OCA(OpticallyClearAdhesive) for the extraordinary glue paste of cementing transparent optical element (as camera lens etc.).Requirement have water white transparency, light transmission rate more than 90%, consolidation strength is good, can solidify under room temperature or middle temperature, and have the features such as cure shrinkage is little.
OCA optical cement is one of starting material of important touch-screen.That optics acryl glue is made without base material, then at upper and lower bottom, then one deck release film of respectively fitting, be a kind of Double-face adhesive rubber alloy band without body material.It is the best tackiness agent of touch screen.Its advantage is clarity, high light transmittance (full light transmittance >99%), high adhesion force, high durable, water tolerance, high temperature resistant, uvioresistant, controlled thickness, there is provided uniform spacing, long-time use can not produce yellow (xanthochromia), stripping and rotten problem.
Existing have the heavy film (as Fig. 1, the heavy film of this kind of OCA product is the same with light film size, and when carrying out CG laminating, operator is difficult to the weight film distinguishing product, thus badly influences production efficiency and good article rate) stacked gradually.
Heavy film, also referred to as heavy film, upper epidermis film, corresponding, light film, is also light-duty film, is also called following table tunic.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of OCA film with heavy film marking, and this OCA membrane structure with heavy film marking is simple, easy to implement, is convenient to distinguish weight film.
The technical solution of utility model is as follows:
There is an OCA film for heavy film marking, comprise the heavy film, OCA glue-line (2) and the light-duty film that stack gradually; Heavy film has at least one laterally rectilinear marking (3).
Described marking is 2, and 2 markings are arranged in parallel.
OCA glue-line is square glue-line, and heavy film is provided with 4 alignment marks (5); 4 alignment marks lay respectively at the outside of 4 folding corner regions of OCA glue-line, and alignment mark is L shape.
The side edge of OCA glue-line is provided with arc notch, OCA glue-line of taking during convenient operation.
Marking and alignment mark can be the indentations that cutter is formed, and also can be the marks existed with silk-screen layer form.
Beneficial effect:
The OCA film with heavy film marking of the present utility model, heavy film arranges two lines and marking is distinguished.Thus make the OCA product that the heavy film of this type is the same with light film size, when carrying out CG laminating, operator is easy to the weight film distinguishing product, improves production efficiency.
In addition, owing to have employed multiple alignment mark, CG abutted equipment can be applied to, when CG abutted equipment can not use bayonet socket to position, alignment mark (also known as " mark " mark) can be adopted to position, thus, greatly reduce this CG abutted equipment and use OCA glue fillet to catch the fraction defective carrying out fitting in location.
Alignment mark can be the mark scribed by cutter, also can mark on silk-screen.
Alignment mark is L shape, also claims fold-line-shaped, is conducive to accurate location.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of existing OCA film.
Fig. 2 is the overall structure schematic diagram with the OCA film of heavy film marking of the present utility model.
The light film skeletal lines of the heavy film of label declaration: 1-, 2-OCA glue-line, 3-marking, 4-arc notch, 5-alignment mark.
Embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As shown in Figure 2, a kind of OCA film with heavy film marking, comprises the heavy film, OCA glue-line 2 and the light-duty film that stack gradually; Light-duty film and heavy film overlap, and its skeletal lines is attached most importance to the light film skeletal lines 1 of film, heavy film has 2 rectilinear markings 3 of transverse direction.
2 markings are arranged in parallel.
OCA glue-line is square glue-line, and heavy film is provided with 4 alignment marks 5; 4 alignment marks lay respectively at the outside of 4 folding corner regions of OCA glue-line, and alignment mark is L shape.
The side edge of OCA glue-line is provided with arc notch 4.
Claims (4)
1. there is an OCA film for heavy film marking, comprise the heavy film, OCA glue-line (2) and the light-duty film that stack gradually; It is characterized in that heavy film having at least one laterally rectilinear marking (3).
