Abstract
The utility model discloses a OCA membrane for preventing overflow and glue, including heavy membrane (1), OCA glue film (3) and light film (2) that stack gradually, the height that highly is greater than the OCA glue film of heavy membrane, the width of heavy membrane is greater than the width of OCA glue film. Light film's the height that highly is greater than the OCA glue film, light film's width is greater than the width of OCA glue film, the height that highly equals light film of heavy membrane, the width of heavy membrane is greater than light film's width. The OCA glue film is located the middle part of heavy membrane, and the border that overlaps with the OCA glue film is all left not to the upper and lower, left and right of heavy membrane. Side department respectively is equipped with 2 counterpoint bayonet sockets about heavy membrane. This a OCA membrane for preventing overflow and glue simple structure, easy to carry out can effectively prevent to overflow and glue.
Description
Technical field
The utility model relates to a kind of for preventing the OCA film of excessive glue.
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, heavy film be the same with OCA glue size, and this product structure saves material to a certain extent.But shortcoming is also very outstanding: 1. product is easily dirty; 2. product easily produces the glue that overflows in transport collision; Be unfavorable for tearing off heavy film during 3.CG laminating, be easy to cause heavy film to draw glue bad).Therefore, be necessary to design a kind of novel OCA film.
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 for preventing the OCA film of excessive glue, and this is used for preventing the OCA membrane structure of excessive glue simple, easy to implement, can effectively prevent excessive glue.
The technical solution of utility model is as follows:
For preventing an OCA film for excessive glue, comprise the heavy film (1), OCA glue-line (3) and the light-duty film (2) that stack gradually; The height of heavy film is greater than the height of OCA glue-line, and the width of heavy film is greater than the width of OCA glue-line.
The height of light-duty film is greater than the height of OCA glue-line, and the width of light-duty film is greater than the width of OCA glue-line; The height of heavy film equals the height of light-duty film, and the width of heavy film is greater than the width of light-duty film.
OCA glue-line is positioned at the middle part of heavy film, and not overlapping with OCA glue-line edge is all left in the upper and lower, left and right of heavy film.
The left and right side edge of heavy film is respectively provided with 2 contraposition bayonet sockets (i.e. square breach, accurate contraposition when fitting for OCA product).
Beneficial effect:
Of the present utility model for preventing the OCA film of excessive glue, owing to increasing the size of the heavy film of product, make it larger than OCA glue-line size, its advantage is: 1. reduce the dirty of product; 2. prevent from colliding the generation causing excessive glue in transit; 3. when being convenient to CG laminating, tear the heavy film of product off, thus, greatly increase production good article rate.
In addition, contraposition bayonet socket be arranged so that OCA film can fit time exactitude position, add success ratio and the good article rate of pad pasting.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of existing OCA film.
Fig. 2 is of the present utility model for preventing the overall structure schematic diagram of the OCA film of excessive glue.
The heavy film of label declaration: 1-, the light-duty film of 2-, 3-OCA glue-line.
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 for preventing the OCA film of excessive glue, comprise the heavy film 1, OCA glue-line 3 and the light-duty film 2 that stack gradually; The height of heavy film is greater than the height of OCA glue-line, and the width of heavy film is greater than the width of OCA glue-line.
The height of light-duty film is greater than the height of OCA glue-line, and the width of light-duty film is greater than the width of OCA glue-line; The height of heavy film equals the height of light-duty film, and the width of heavy film is greater than the width of light-duty film.
OCA glue-line is positioned at the middle part of heavy film, and not overlapping with OCA glue-line edge is all left in the upper and lower, left and right of heavy film.
The left and right side edge of heavy film is respectively provided with 2 contraposition bayonet sockets (i.e. square breach, accurate contraposition when fitting for OCA product), and contraposition bayonet socket is not shown in the drawings.
Claims (4)
1. for preventing an OCA film for excessive glue, it is characterized in that, comprising the heavy film (1), OCA glue-line (3) and the light-duty film (2) that stack gradually; The height of heavy film is greater than the height of OCA glue-line, and the width of heavy film is greater than the width of OCA glue-line.
2. according to claim 1ly it is characterized in that for preventing the OCA film of excessive glue, the height of light-duty film is greater than the height of OCA glue-line, and the width of light-duty film is greater than the width of OCA glue-line; The height of heavy film equals the height of light-duty film, and the width of heavy film is greater than the width of light-duty film.
