Description

Film coating device capable of eliminating glue piling of roll-to-roll nano metal imprinting plate seam

Technical Field

The utility model relates to a technical field of nanometer impression, in particular to can eliminate volume to volume nanometer metal impression version seam and pile tectorial membrane device of gluing.

Background

The nano-imprinting technology is a low-cost and fast method for obtaining a copy structure in a nano-scale, can repeatedly prepare high-precision micro-nano pattern structures on large-area materials such as films in a large scale, and the prepared high-resolution patterns have quite good uniformity and repeatability. Currently, the nanoimprint technology is widely applied to the fields of photoelectric devices, semiconductors and the like as a novel high-efficiency and high-yield micro-nano structure preparation technology. At present, the nanoimprint technology is developing towards large area, low cost, micro-nano size and integration.

There are currently two main forms of nanoimprint technology.

One is a direct mechanical contact hot stamping method. The pattern transfer in the hot pressing mode is realized by heating a circular mould pressing roller on a mould pressing machine, a non-setting adhesive is used for attaching a nickel plate on the mould pressing roller or a clamping plate is used for clamping the nickel plate, the micro-nano pattern is arranged on the nickel plate, and the micro-nano structure is pressed on the film with transfer resin in a simultaneous heating and pressurizing mode. The method has the defects that the transfer effect of the micro-nano structure is influenced by various factors such as temperature, pressure, different resins, roller uniformity and the like, the stability of the pattern effect of the micro-nano structure in the long-time transfer process is difficult to ensure, the micro-nano structure is unstable or incomplete due to slight change of the mould pressing condition, and the quality of a transferred image is difficult to effectively ensure. Meanwhile, the molding roller needs to be polished regularly, the service life of the molding roller is short, and high cost is needed. Meanwhile, the heat transfer of the hot pressing mode takes time, so the hot pressing efficiency is low.

The other method is ultraviolet curing. Currently, flat pressing or roller pressing is generally adopted when ultraviolet curing nano-pressing is carried out to copy a microstructure. Wherein, the flat pressing speed is slow, the efficiency is low, and the continuous microstructure can not be prepared; however, the current roller imprinting generally adopts a metal nickel master plate to be adhered to a roller for imprinting, for example, in the texture transfer film disclosed in chinese patent application No. 202011520316.5 and the preparation method thereof, roll-to-roll roller nanoimprinting has high efficiency, but the current common process cannot realize seamless continuous rolling. A plate seam exists when the metal nickel master plate is attached to the roller. The plate seam has a certain depth due to the height difference of the nickel master plate. UV glues constantly to pile up in the seam at the nanometer impression in-process, and during photocuring, the unnecessary UV of seam that comes not as late as complete solidification glues and can be retransferred to the membrane material, and the membrane material passes through subsequent deflector roll again, and these UV glues can be retransferred to the surface of different deflector rolls many times and move to the different places of membrane material behind. After repeated transfer printing for many times, the structural surface of the membrane material is adhered with UV glue, and the adhesion of redundant UV glue on the structural surface can cause irregular flaws of the nano microstructure pattern and irregular loss of the nano microstructure, so that the transfer quality is seriously affected, and the transfer yield is very low.

Although patent documents report that plate seam glue accumulation can be avoided by electroforming a cylindrical nickel plate, for example, a holographic laser cylindrical plate manufacturing method disclosed in CN108957961A, a corresponding circular nickel plate electroforming system such as CN204162816U, a circular nickel plate stripping system such as CN211603845U and a coater need an inflatable plate roller such as CN110614210A, which relate to updating of a series of devices and modification of machine equipment.

There are also patent documents reporting that the problem of plate joint stacking can be solved by preparing epoxy resin plate rolls, such as CN113976406A, but the actual test results cannot completely solve the problem. Because the nickel plate is made of metal and the UV glue is a high molecular organic matter, the property difference between the nickel plate and the UV glue is large, and most of the solidified UV resin has poor bonding force with the nickel plate and is easy to peel. Although the printing roller made of epoxy resin instead of the nickel plate is thin in resin and continuous in structure, the problem of glue stacking at the seam of the printing roller can be solved, another problem is generated in practical tests, namely that the cured UV glue and the microstructure layer on the printing roller made of epoxy resin are both high-molecular organic compounds during nano-imprinting, and the stripping force of the UV glue and the microstructure layer is larger than that of the nickel plate and the nano-imprinting glue. The microstructure of the epoxy resin printing roller is transferred for many times, and compared with a nickel plate, the micro structure of the epoxy resin printing roller is more easily provided with adhesive, and the micro structure on the printing roller is more easily flawed and dropped, so that the service life of the epoxy resin printing roller is greatly shortened, the epoxy resin printing roller cannot be efficiently and continuously produced in large quantities, and the printing roller needs to be frequently replaced with a new printing roller. Meanwhile, the preparation technology of the plate roller has high precision requirement and long preparation time, and a small flaw needs to be started again.

In conclusion, it is very practical to explore a method with high efficiency, low modification cost and low maintenance cost for mature nano-imprinting process and commercial equipment in the market to solve the problem of plate seam glue piling in the roll-to-roll nano-imprinting process.
