Abstract
The utility model relates to the technical field of processing equipment for electronic optical cement, and particularly to a cutting knife die for electronic optical cement, which is characterized in that: the edge of a cutting knife blade is a single-side inclined edge; the inclined side of the edge is located on a closed ring-shaped outer side, so that a blade on a closed ring-shaped inner side is a straight side. In cutting, the cutting knife die does not extrude a cutting port, thus protecting the edge of the needed optical cement layer from deformation due to extrusion; in addition, after the cutting is finished, the straight surface of the edge is contacted with an inner ring of the optical cement layer, and at least one de-bonding layer is arranged on the outer layer of the optical cement layer for protection; and, in a lifting progress of the knife, the optical cement layer is not easily bonded on the inclined surface of a knife point, so that the edge surface of the optical cement layer is protected from scratch, and quality of the annular optical cement layer is ensured.
Description
Technical field
The utility model relates to electron-optical glue technical field of processing equipment, refers in particular to a kind of electron-optical glue with cutting cutting die.
Background technology
Electron-optical glue (OCA) is a kind of no base material double-sided adhesive tape of the clean high grade of transparency, and its properties of transparency is good, and light transmittance reaches more than 99%; At strong illumination, hot and humid environment uses also harmless outward appearance down; The plastic material of suitable stickup Merlon etc.; Be mainly used in the stickup between touch-screen (capacitance plate, resistance screen) and the front panel at present, be widely used in smart mobile phone, handwritten computer, the use of touch screen multimedia machine, have vast market.
Electron-optical glue covers a leafing shape layer 4 at least respectively on the two sides of optics glue-line 3; Before use, cut into the ring-shaped material of required size, make the shape layer 4 that leaves of one side wherein shear consistent with the profile of optics glue-line 3; Another leaves the peripheral profile of the peripheral profile of shape layer 4 greater than optics glue-line 3; Therefore need fall optics glue-line 3 and cover a leafing shape layer 4 above that with the cutting apparatus cutting, single again blocking forms shape as shown in Figure 1; It is very high to cut in the process quality requirement for the optics glue-line; Guarantee the quality of ring optics glue-line in the ring-type; Can not form on the edge of and shear irregular or the knife edge causes pulls phenomenon, use such optics glue-line after on the product, product can form serious quality problems at injury site.At the existing cutting die that cuts that is used to cut the optics glue-line, general Tool Design becomes the two-sided blade that puts the first edge on a knife or a pair of scissors, and when cutting, knife edge both sides all are the inclined-planes, and both sides cut through downward extruding, cause the crimp at optics glue-line edge easily; In addition, when cutting completion, the inclined-plane of the knife edge contacts with the optics glue-line, and in the process of griffing, the optics glue-line sticks on the inclined-plane of the knife edge easily, thereby pulls the edge surface of optics glue-line, causes product quality problem.
The utility model content
The utility model is to cut the deficiency that cutting die exists to present electron-optical glue when cutting, and provides a kind of electron-optical glue that overcomes the above problems with cutting cutting die.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electron-optical glue is with cutting cutting die, and the said blade that cuts that cuts cutting die is arranged on the cutting die plate, cuts the setting of blade closed circular, and the said blade that cuts blade puts the first edge on a knife or a pair of scissors for the single face hypotenuse, and the said hypotenuse that puts the first edge on a knife or a pair of scissors is in the outside of closed circular.
The beneficial effect of the utility model is: the blade of the cutting edge of the utility model puts the first edge on a knife or a pair of scissors for the single face hypotenuse; The hypotenuse that puts the first edge on a knife or a pair of scissors is in the outside of closed circular; Therefore the blade in the inboard of closed circular is a straight flange; Cause extruding, the crimp that causes optics glue-line edge that can not cause needs to use cutting the Shi Buhui otch that cuts into two exact halves; In addition, when cutting completion, facing directly with interior ring optics glue-line of blade contacts; Optics glue-line skin also also has leafing shape layer protection at least, and in the process of griffing, the optics glue-line is difficult for sticking on the inclined-plane of the knife edge; Can not pull the edge surface of optics glue-line, guarantee the quality of optical ring glue-line.

Fig. 2 cuts the structural representation of cutting die for the utility model
Fig. 3 cuts the cutting edge edge structure sketch map of cutting die for the utility model
The specific embodiment
Do further to set forth below in conjunction with 2,3 pairs of the utility model of accompanying drawing:
A kind of electron-optical glue is with cutting cutting die, and the blade 1 that cuts that cuts cutting die is arranged on the cutting die plate 2, cuts blade 1 closed circular setting, and the blade that cuts blade 1 is that single face hypotenuse 11 puts the first edge on a knife or a pair of scissors, and the hypotenuse 11 that puts the first edge on a knife or a pair of scissors is in the outside of closed circular.
The blade of the cutting edge 1 of the utility model is that single face hypotenuse 11 puts the first edge on a knife or a pair of scissors; The hypotenuse 11 that puts the first edge on a knife or a pair of scissors is in the outside of closed circular; Therefore the blade 1 in the inboard of closed circular is a straight flange; Cause extruding, the crimp that causes optics glue-line edge that can not cause needs to use cutting the Shi Buhui otch that cuts into two exact halves; In addition, when cutting completion, facing directly with interior ring optics glue-line of blade contacts; Optics glue-line skin also also has leafing shape layer protection at least, and in the process of griffing, the optics glue-line is difficult for sticking on the inclined-plane of the knife edge; Can not pull the edge surface of optics glue-line, guarantee the quality of optical ring glue-line.
The above embodiment; It is the preferred embodiments of the utility model; Be not to limit the utility model practical range,, all should be included in the utility model patent claim so all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify.
