Abstract
The utility model discloses a OCA membrane with alignment mark, including the heavy membrane that stacks gradually 1, OCA glue film 3 and light film 2, heavy epimembranal 4 alignment marks 4 that are equipped with, the OCA glue film is square glue film, and the alignment mark is located the regional outside in bight of OCA glue film. 4 individual alignment mark is located the regional outside in 4 bights of OCA glue film respectively. Heavy epimembranal a plurality of counterpoint bayonet sockets that still are equipped with. The last side department of heavy membrane is equipped with 2 counterpoint bayonet sockets, and the lower side department of heavy membrane is equipped with 1 counterpoint bayonet socket. This OCA membrane with alignment mark can effectively prevent the dislocation of pad pasting, ensures the yields of product.
Description
Technical field
The utility model relates to a kind of OCA film with alignment mark.
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 stacked gradually (as Fig. 1, existing OCA film, (i.e. heavy film, also referred to as upper epidermis film for its heavy film, corresponding, light film, is also light-duty film, is also called following table tunic) design without contraposition, OCA glue fillet is adopted to carry out contraposition laminating during CG laminating, be difficult to realize accurately aiming at, easily cause the waste of material, and cause the fraction defective of product to rise.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of OCA film with alignment mark, and this OCA film with alignment mark effectively can prevent the dislocation of pad pasting, is conducive to the good article rate ensureing product.
The technical solution of utility model is as follows:
There is an OCA film for alignment mark, comprise the heavy film (1), OCA glue-line (3) and the light-duty film (2) that stack gradually; Heavy film is provided with at least 2 alignment marks (4);
OCA glue-line is square glue-line, and alignment mark is positioned at the outside of the folding corner region of OCA glue-line.
Described alignment mark is 4, and 4 alignment marks lay respectively at the outside of 4 folding corner regions of OCA glue-line.
Heavy film is also provided with multiple contraposition bayonet socket.As in Fig. 2, the upper side edge place of heavy film is provided with 2 contraposition bayonet sockets, and the lower side place of heavy film is provided with 1 contraposition bayonet socket.
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.
Beneficial effect:
The OCA film with alignment mark of the present utility model, 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.
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 alignment mark of the present utility model.
The heavy film of label declaration: 1-, the light-duty film of 2-, 3-OCA glue-line, 4-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 alignment mark, comprises the heavy film 1, OCA glue-line 3 and the light-duty film 2 that stack gradually; Heavy film is provided with 4 alignment marks 4;
OCA glue-line is square glue-line, and 4 alignment marks lay respectively at the outside of 4 folding corner regions of OCA glue-line.
Heavy film is also provided with multiple contraposition bayonet socket.The upper side edge place of heavy film is provided with 2 contraposition bayonet sockets, and the lower side place of heavy film is provided with 1 contraposition bayonet socket.
