Embodiment 1

[0041] A surface microstructure processing device based on roll-to-roll UV curing polymer film, its structure is as follows figure 1 As shown, it includes a set of forward imprinting equipment and a set of reverse imprinting equipment. The forward imprinting equipment includes an unwinding device, a coating device, a rolling device, a UV curing device, a protective film sticking device, and a winding device arranged in sequence. Device; Reverse embossing equipment and forward imprinting equipment share unwinding device and rewinding device, in addition, it also includes independent coating device, rolling device, UV curing device.

[0042] The unwinding device includes an unwinding roller 1, a deviation correction device 3, a tension control device 4, and a driving roller 5; the tension control device 4 is provided with a tension sensing device, and the control system is connected to the tension control device 4 to sense the film to be embossed and the embossed film When the t...

Embodiment 2

[0059] Such as figure 2 As shown, based on the implementation case 1, the reverse imprinting equipment is moved to the lower left as a whole to ensure that there is a larger wrap angle between the substrate 2 and the reverse mold roll 12, and increase the transfer contact time and shape retention time, thereby ensuring a better Good reverse transfer effect.

[0060] The size of the microstructure pattern on the forward-cured surface is 30 μm, the size of the microstructure pattern on the reverse-cured surface is 5 μm, the thickness of the substrate film is 80 μm, and its material is polyester (PET, Polyester).

[0061] The advantage of this case is: due to the downward movement of the reverse rolling device, there is a longer contact distance and a larger shape retention angle between the reverse mold roller and the substrate, which increases the shape retention time and better guarantees Molding quality of reverse transfer printing.

Embodiment 3

[0063] A surface microstructure processing device based on roll-to-roll UV curing polymer film, such as image 3 As shown, it includes a set of forward imprinting equipment and a set of reverse imprinting equipment. The forward imprinting equipment includes an unwinding device, a coating device, a rolling device, a UV curing device, a protective film sticking device, and a winding device arranged in sequence. Device; Reverse embossing equipment and forward imprinting equipment share unwinding device and rewinding device, in addition, it also includes independent coating device, rolling device, UV curing device. The unwinding device, the protective film sticking device and the rewinding device are all the same as the implementation case 1.

[0064] The forward ultraviolet curing device is similar to the embodiment 1, except that the rubber roller 9 is placed on the top of the mold roller 10, while the rubber roller 9 is placed below the mold roller 10 in the embodiment 1;

[0...

Abstract

The invention relates to roll-to-roll based UV cured polymer film surface microstructure processing system and method. The processing system is formed by combining a forward impression apparatus and a reverse impression apparatus in order arrangement; the forward impression apparatus comprises an unreeling device, a coating device, a rolling device, a UV curing device and a winder in order arrangement; the reverse impression apparatus comprises the unreeling apparatus and the winder shared with the forward impression apparatus and independent coating device, rolling device and UV curing device. Two groups of rolling devices are propped against each other, the UV curing devices are respectively used for orderly transferring both sides of the substrate film, exposing and curing; the processing method comprises an unreeling step, a gluing curing step, a protective film pasting step, and a winding step. Compared with the prior art, the optical film two-sided processing in different glue line textures, different structural features and different grain depths can be realized by using the system and method disclosed by the invention.

Description

technical field [0001] The invention relates to the field of film polymer material manufacturing, in particular to a roll-to-roll UV curing polymer film surface microstructure processing system and method. Background technique [0002] Processing microstructures with different geometric features on thin-film polymer materials can endow them with different optical properties, such as light uniformity, anti-reflection, reflective light, etc. Due to its lightness and easy large-scale processing, these optical films with surface fine structure are widely used in the displays of smartphones, notebook computers, tablet computers, TVs, etc., and because the development trend of these electronic products is towards light and thin With the development of globalization, the display screen is getting thinner and thinner, which puts forward the requirements for the integration of optical films, and integrates multi-layer optical performance films into a few layers to achieve the purpose...
