Description

Technical Field

[0001] The utility model relates to the field of optical films, in particular to an optical film which is easy to peel off. Background Art

[0002] Optical film is a type of optical medium material that is composed of thin layered media and transmits light beams through interfaces. The characteristics of optical thin films are: the surface is smooth, and the interfaces between film layers are geometrically divided; the refractive index of the film layer can jump on the interface, but it is continuous within the film layer; it can be a transparent medium or an absorbing medium; it can be normal uniform or normal non-uniform. The thin films used in actual applications are much more complicated than ideal thin films. This is because: during preparation, the optical and physical properties of the film deviate from the bulk material, and its surface and interface are rough, which leads to diffuse scattering of the light beam; the mutual penetration between the film layers forms a diffusion interface; the anisotropy of the film is formed due to the growth, structure, stress and other reasons of the film layer; the film layer has a complex time effect.

[0003] After the optical film is produced, protective films are usually attached to both sides for protection. A pull tab is fixed on the protective film to facilitate peeling off the protective film. However, when the protective film is peeled off by the pull tab, the pulling force is too large and the protective film may be easily damaged. Therefore, the market urgently needs to develop an optical film that is easy to peel off to help people solve the existing problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-5 The utility model provides an embodiment: an optical film that is easy to peel off, including a protective frame 1, a movable groove 101 is arranged on the inner side end surface of the protective frame 1, a plurality of guide pillars 102 are fixedly arranged inside the movable groove 101, a hard transparent protective film 2 is connected to the inside of the protective frame 1, a plurality of adhesive pillars 202 are arranged in an array at the lower end of the hard transparent protective film 2, an optical film 4 is adhered to the lower ends of the plurality of adhesive pillars 202, a bonding groove 104 is arranged on the lower end surface of the protective frame 1, an adhesive layer 105 is fixedly arranged on the upper end of the bonding groove 104, a lower protective film 5 is connected to the inside of the bonding groove 104, and L-shaped buckle parts 501 are fixedly connected to the middle parts of both sides of the lower end surface of the lower protective film 5.

[0024] Furthermore, a support frame 3 is fixedly connected to the upper end surface of the hard transparent protective film 2, a cross support frame 301 is fixedly connected inside the support frame 3, and a pressing plate 302 is fixedly connected to the middle of the end surfaces on both sides inside the support frame 3. By pressing the pressing plate 302, the support frame 3 is driven down, and then the support frame 3 drives the hard transparent protective film 2 to descend. At the same time, the stability of the hard transparent protective film 2 is ensured by the cross support frame 301.

[0025] Furthermore, a plurality of circular openings 201 are provided on both sides of the interior and on the front and rear ends of the hard transparent protective film 2 .

[0026] Furthermore, the edges of the hard transparent protective film 2 extend to the inside of the movable groove 101 and allow the guide column 102 to pass through the circular opening 201. The guide column 102 guides the lifting and lowering of the hard transparent protective film 2 in the movable groove 101 to ensure the stability of the lifting and lowering of the hard transparent protective film 2.

[0027] Furthermore, a spring 103 is provided on the side surface of the guide column 102 and at the lower end of the hard transparent protective film 2 .

[0028] Furthermore, each adhesive column 202 is fixedly connected to an adhesive head 203 at the lower end, and the lower end of the adhesive column 202 is adhered to the upper end surface of the optical film 4 through the adhesive head 203. When the hard transparent protective film 2 descends, the spring 103 is compressed. When the optical film 4 is in contact with the bonding surface, the support frame 3 is pulled up to lift the hard transparent protective film 2. The spring 103 assists the hard transparent protective film 2 to rise, so that the adhesive head 203 at the lower end of the adhesive column 202 is separated from the upper end of the optical film 4. Through the dot matrix arrangement of the adhesive columns 202, the bonding area between the hard transparent protective film 2 and the optical film 4 is greatly reduced, so that after the optical film 4 is bonded, the hard transparent protective film 2 is pulled to separate the adhesive head 203 from the upper end of the optical film 4.

[0029] Furthermore, the upper end surface of the lower protective film 5 is bonded to the adhesive layer 105, and the lower end of the optical film 4 is protected from dust by the lower protective film 5. When the optical film 4 is pasted, the two L-shaped buckles 501 on the lower end surface of the lower protective film 5 are pulled to pull the lower protective film 5 out from the adhesive groove 104.

[0030] Working principle: When in use, first pull the lower protective film 5 out of the adhesive groove 104. This step is achieved by pulling the two L-shaped buckle pullers 501 on the lower end surface of the lower protective film 5, so that the lower protective film 5 is separated from the adhesive layer 105, thereby exposing the lower end surface of the optical film 4. Next, place the entire protective frame 1 at the position where the optical film 4 needs to be bonded, ensure that the position of the optical film 4 is aligned with the bonding surface, and drive the support frame 3 to descend by pressing the pressing plate 302, so that the support frame 3 drives the hard transparent protective film 2 to descend, and the edges of the hard transparent protective film 2 extend to the inside of the movable groove 101 and the guide column 102 passes through the circular opening 201. The guide column 102 guides the lifting and lowering of the hard transparent protective film 2 in the movable groove 101 to ensure the stability of the lifting and lowering of the hard transparent protective film 2. When the hard transparent protective film 2 is lowered into place and the optical film 4 is tightly bonded to the bonding surface, the optical film 4 and the hard transparent protective film 2 are connected by the bonding head 203 at the lower end of the bonding column 202. Next, pull up the support frame 3, which will drive the hard transparent protective film 2 to rise. In this process, the spring 103 will assist the hard transparent protective film 2 to rise, and gradually separate the adhesive head 203 at the lower end of the adhesive column 202 from the upper end of the optical film 4. Since the adhesive column 202 is arranged in a dot matrix, the bonding area between the hard transparent protective film 2 and the optical film 4 is greatly reduced. Therefore, when the hard transparent protective film 2 is pulled, the adhesive head 203 can be easily separated from the upper end of the optical film 4. When the optical film 4 is completely bonded to the bonding surface and the hard transparent protective film 2 is completely separated from the optical film 4, the protective frame 1 can be removed from the optical film 4 together with the hard transparent protective film 2, completing the entire peeling process.
