Embodiment Construction

[0016] specific implementation plan

[0017] The working principle of the polymer extrusion micro-imprint molding method of the present invention is as attached figure 2 As shown, the extruder (1) extrudes the polymer substrate (3) required for micro-imprinting through the extruder head (2), and the polymer substrate (3) passes through the two pre-sets of the flattening and thickness adjustment device. The flattening thickness control roller (4) performs flattening and thickness adjustment to ensure the uniformity of the thickness of the polymer substrate (3). After flattening, the polymer substrate (3) enters the heating and heat preservation device (5) to control its surface temperature at the set process temperature. Then, the polymer substrate (3) enters between the embossing roller (6) and the support roller (7), wherein the embossing roller (6) is equipped with a hot embossing mold, by virtue of the embossing roller ( 6) and the pressure between the supporting roller (...

Abstract

Polymer micro embossing is a shaping method for forming micro-nano-structured patterns on polymer substrate materials by hot embossing. Polymer micro embossing method is widely applied in the manufacturing of various polymer micro-nano structures. The experiment apparatus mainly comprises: a polymer substrate extruder, a substrate pressing and thickness adjusting apparatus, a temperature controlling apparatus, an embossing apparatus, a pressure controlling apparatus, a pressure maintaining cooling apparatus, and a pulling apparatus. The pressing and thickness adjusting apparatus is used for flattening the extruded polymer; the temperature controlling apparatus is used for ensuring the surface temperature of the polymer substrate requiring flattening; the embossing apparatus is provided with embossing molds with micro embossing structures, wherein the micro embossing structures are transferred with applied pressures; the pressure controlling apparatus is used for adjusting the pressures applied to the polymer substrate; and the pressure maintaining cooling apparatus is used for cooling and shaping the micro structures. With the shaping method, a large amount of time and energy required by heating and cooling can be saved, the embossing equipment can be greatly simplified, the production efficiency is high, the operation is simple, and the cost is low.

Description

technical field [0001] The invention relates to a polymer extrusion micro-embossing molding method, which is mainly used for pressing microstructure patterns on the surface of polymer substrates. The application fields mainly include: polymer gratings, polymer light guide plates, polymer-based radiators, Polymer microelectromechanical systems, polymer microfluidic chips, and the production of integrated circuit boards. Background technique [0002] Polymer hot embossing is a new graphic replication technology. Compared with traditional photolithography technology, it has the following characteristics: simple equipment, convenient operation, simple process (less process parameters), high precision of microstructure replication, Low processing costs and more expensive molds only need to be processed once to achieve mass replication of the same microstructure. In recent years, due to the increasing demand for microstructure products, its development speed has also become faster...
