Embodiment 1

[0032] Embodiment one: see attached figure 1 as shown, figure 1 It is a roll-to-roll ultraviolet nanoimprinting device of the present invention, comprising: a transmission device, a coating device, a pre-curing device, an embossing device, a strong curing device and a cooling device.

[0033] Wherein the conveying device at least includes a discharge roller 1 and a take-up roller 15, which are located at both ends of the entire embossing device, and the cylindrical roll-up material to be embossed is placed on the discharge roller 1, and its open end is wound to The take-up roller 15, when the embossing is turned on, the unwinding roller 1 and the take-up roller 15 rotate at the same linear speed in the opposite direction of the material winding, so that the material to be embossed is transported along the specified route. The transmission device also includes auxiliary rollers 2, 8, and 12, which are respectively located on the entire transmission route, and these auxiliary r...

Embodiment 2

[0038] Embodiment two: embodiment two is on the basis of embodiment one, on discharge roller 1 and receiving roller 15, two rectification systems before and after are set, as Figure 5 As shown, the deviation correction system includes a material edge sensor and a transmission repair device. The material edge sensor can be an infrared sensing device 17, and the conveying and repairing device is provided with an axial displacement device 18 on the discharging roller 1 and the receiving roller 15, and the two are electrically connected. When the infrared sensing device 17 senses that the material is shifted inward during the conveying process, the axial displacement device 18 controls the discharging roller 1 or the receiving roller 15 to move inward, otherwise the displacement occurs outward. The two deviation correction systems make the front and rear displacement errors within 30um during the transmission of the imprinted materials, thus eliminating the need for alignment ste...

Embodiment 3

[0039] Embodiment 3: Embodiment 3 is based on Embodiment 1 or Embodiment 2, and further includes a tension control system, which is arranged on any number of rollers that play a role in transmission, such as Figure 6 shown. The tension control system is mainly composed of a tension sensing device 19 and a magnetic powder clutch device 20. When the tension sensing device 19 finds that the tension is greater than a preset value during material transmission, the magnetic powder clutch device 20 slightly reduces the winding speed. At the preset value, the magnetic powder clutch device 20 slightly increases the winding speed. The predetermined value may be the deformation rating of the material or other value that may affect the surface tension of the material. Through the tension control system, it is ensured that the material is always in a state of tension during the embossing process, avoiding the generation of waste products caused by wrinkles, and improving the production y...

Abstract

The invention discloses a reel-to-reel ultraviolet nanometer coining device and a reel-to-reel ultraviolet nanometer coining method. The device comprises a conveyance device, a coating device, a pre-curing device, a coining device and a reinforced-curing device. A material to be coined is conveyed by the conveyance device, uniformly coated with ultraviolet glue by the coating device, leveled and half-cured by the pre-curing device, conveyed to the coining device for coining and finally cured and molded by the reinforced-curing device. Compared with the conventional nanometer coining technology, the coining device of the invention has higher production efficiency and yield. The invention also discloses a method for realizing reel-to-reel ultraviolet nanometer coining by utilizing the device.

Description

technical field [0001] The invention relates to an ultraviolet nanoimprinting device and method, in particular to a roll-to-roll ultraviolet nanoimprinting device and method. Background technique [0002] Since the nanoimprint technology was proposed in 1995, people hope to achieve low-cost, high-resolution, high-efficiency, large-area batch preparation of nanostructures through this technology. However, the traditional thermal embossing technology requires heating and high pressure, which makes the embossing process complicated and difficult to control. In 1999, a research team at the University of Texas in the United States proposed a UV nanoimprinting technology that uses ultraviolet light (UV) to cure polymers at room temperature and low pressure. [0003] At present, nanoimprinting technology mainly includes the following types: [0004] (1) Hot embossing. First, the hard stamper blank is processed into a stamper, and then the high molecular polymer material is spin-...
