In the process of LCD and OLED modules, a Polaroid (POL) is required to be attached to the surface of a Panel (Panel), and the attachment of the polaroid can reduce the influence of external reflected light, and improve the display color contrast of the Panel, so that the display effect of the Panel is improved.

In order to make the person skilled in the art better understand the solution of the present utility model, the technical solution of the embodiment of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

The embodiment of the utility model provides a light-emitting device film sticking roller, as shown in fig. 1, which comprises a roller main body 10 and a micropore suction nozzle layer 20, wherein the micropore suction nozzle layer is arranged on the periphery of the roller main body 10 and is used for adsorbing a film to be attached. The membrane may be a polarizer or other functional membrane, such as a protective film, a barrier film, etc. The technical scheme of the embodiment of the utility model is explained by taking the diaphragm as a polarizer as an example.

In this embodiment, the microporous suction nozzle layer may be disposed on the entire outer periphery of the drum body 10, or may be disposed on a portion of the outer periphery of the drum body 10 according to actual needs, so as to save consumables. Of course, the microporous suction nozzle layer in this embodiment can be reused, and the experiment can be repeated for 3000-4000 times, which is also beneficial to saving consumables.

In a specific embodiment, the size of the spreading surface of the micro-hole suction nozzle layer 20 is adapted to the polarizer to be attached, in the whole, the size of the spreading surface of the micro-hole suction nozzle layer 20 is not smaller than the size of the polarizer to be attached, and is not larger than the size of the outer peripheral surface of the drum body 10, and when the size of the spreading surface of the micro-hole suction nozzle layer 20 is between the polarizer to be attached and the outer peripheral surface of the drum body 10, the micro-hole suction nozzle layer 20 can be disposed at any position of the outer peripheral surface of the drum body 10.

In some embodiments, as shown in fig. 3, the micro-porous suction nozzle layer 20 includes a micro-porous suction nozzle adsorption layer 21 and a micro-porous suction nozzle adhesive layer 22 which are laminated, and the micro-porous suction nozzle adhesive layer 22 is adhered to the outer circumference of the drum body 10, that is, the micro-porous suction nozzle adhesive layer 22 functions to adhere the micro-porous suction nozzle adsorption layer 21 to the drum body 10.

To ensure the film-sticking effect, the micro-porous suction nozzle adsorption layer 21 and the micro-porous suction nozzle adhesive layer 22 are required to meet some adhesive requirements in the preferred embodiment. In this embodiment, the polarizer to be attached is specifically formed by sequentially laminating a release film, a polarizer colloid, a polarizer body and a protective film. The release film can prevent the polaroid colloid from introducing sundries and the polaroids from adhering together; the polaroid colloid is used for adhering the polaroid body and the panel of the light-emitting device together to realize attachment and fixation; the protection film can protect the polaroid body from being scratched, polluted and the like in the transferring process. In this embodiment, the adhesion requirements satisfied by the micro-porous suction nozzle adsorption layer 21 and the micro-porous suction nozzle adhesion layer 22 are specifically:

the viscosity of the microporous suction nozzle adsorption layer 21 and the surface of the protective film of the polaroid is larger than the adhesion force of the release film of the polaroid and the polaroid colloid, so that the release film can be conveniently removed in the film pasting process flow; meanwhile, the viscosity of the surface of the microporous suction nozzle adsorption layer 21 and the surface of the polaroid protective film is smaller than the adhesion force of the polaroid glue material and the panel, so that separation of a roller and the polaroid is facilitated after the polaroid is attached, and the viscosity of the contact surface of the microporous suction nozzle adhesive layer 22 and the roller is larger than the viscosity of the surface of the microporous suction nozzle adsorption layer 21 and the surface of the polaroid protective film, so that the stability of the polaroid is ensured when the polaroid is adsorbed and attached.

In this embodiment, the micro-porous suction nozzle adsorption layer 21 has a plurality of micro-porous suction nozzles, and the micro-porous suction nozzles are irregularly distributed in the micro-porous suction nozzle adsorption layer 21. Specifically, the surface of the micro-pore suction nozzle adsorption layer 21 is formed by numerous micro-pores, the micro-pores are the micro-pore suction nozzles, about 10,000 micro-pores are distributed in every 1 square centimeter of the surface of the micro-pore suction nozzle adsorption layer 21, each micro-pore has a sucking disc function, a safe and stable adsorption force can be provided, and the adsorption force of the micro-pore suction nozzle adsorption layer 21 is finally formed by superposition of the adsorption force of each micro-pore.

In order to ensure that the adsorption force of the micro-porous nozzle adsorption layer 21 meets the adhesion requirement, the micro-porous nozzle of the micro-porous nozzle adsorption layer 21 of the present embodiment has a diameter of 10-50 μm, specifically 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, etc.

In this embodiment, as shown in fig. 4, the deployment surface of the micro-porous suction nozzle layer 20 is rectangular, the rectangular plane shown in the drawing is the surface of the micro-porous suction nozzle adsorption layer 21, the surface of the micro-porous suction nozzle adsorption layer 21 forms a continuous adsorption surface, and the adsorption forces of the areas of the adsorption surface are equivalent. Of course, the spreading surface of the micro-porous suction nozzle layer 20 may have other shapes, such as a circular shape, in order to adapt to the shape of the display panel.

In this embodiment, the adsorption force of the micro-pore nozzle adsorption layer 21 is determined by the diameter and the number of micro-pore nozzles in the unit area of the micro-pore nozzle adsorption layer 21, that is, by setting the diameters and the number of micro-pore nozzles differently, the micro-pore nozzle adsorption layer 21 with different adsorption forces can be obtained. Specifically, the smaller the number of the micro-porous suction nozzles per unit area, the smaller the diameter, the smaller the suction force of the micro-porous suction nozzle suction layer 21.

In some embodiments, referring to fig. 4, the micro-porous nozzle adsorption layer 21 includes a first region 211 and a second region 212; the first area 211 is located at the periphery of the second area 212, and the suction forces of the two areas are different, specifically, the suction force of the micro-hole suction nozzles in the first area 211 is greater than the suction force of the micro-hole suction nozzles in the second area 212.

Specifically, the number of micro-hole suction nozzles in the unit area of the first area 211 is greater than the number of micro-hole suction nozzles in the unit area of the second area 212; and/or the diameter of the micro-pore suction nozzle per unit area of the first region 211 is larger than the diameter of the micro-pore suction nozzle per unit area of the second region 212.

Further, in order to make the adsorption force of the first region 211 of the micro nozzle adsorption layer 21 larger than that of the second region 212, the diameter of the micro nozzle per unit area of the first region 211 is set to be 30 to 50 μm, specifically, 35 μm, 40 μm, 45 μm, etc., and the diameter of the micro nozzle per unit area of the second region 212 is set to be 10 to 30 μm, specifically, 15 μm, 20 μm, 25 μm, etc.

By setting the adsorption force of the peripheral area (the first area 211) of the microporous suction nozzle adsorption layer 21 to be larger than the adsorption force of the inner area (the second area 212), on one hand, the peripheral area is convenient to better adsorb the polaroid in the film pasting process, the phenomenon that the polaroid is warped is prevented, air bubbles are avoided from being generated at corners, on the other hand, the inner area of the microporous suction nozzle adsorption layer 21 can be quickly separated from the polaroid when the polaroid is attached to a light-emitting device panel, the influence of stress deformation on the panel of the light-emitting device is avoided, and the attaching effect is ensured.

Of course, the first area 211 may not be a continuous area, for example, may be a discrete area disposed at four corners of the development surface of the micro-hole suction nozzle adsorption layer 21, or a discrete area disposed at two opposite sides of the development surface of the micro-hole suction nozzle adsorption layer 21, so as to better adsorb the polarizer during the film pasting process and prevent the corners of the polarizer from tilting.

In some embodiments, the main material of the micro-porous suction nozzle adsorption layer 21 is acrylic fiber, and the micro-porous suction nozzle adsorption layer 21 with different diameters and numbers of micro-porous suction nozzles can be formed through the proportioning adjustment of the main material and other materials. In other embodiments, other materials may be selected as the main material according to practical situations, so long as the micro-porous suction nozzle adsorption layer 21 having a plurality of micro-porous suction nozzles can be formed.
