POTOP won the second prize of the “2019 Science and Technology Progress Award of Guangdong Province” after 6-year deep cooperation with Shenzhen University and a lot of research works done in the key technology and industrialization project of injection and rolling forming of polymer microstructure ultra-thin optical devices.
Project introduction: Large-scale high-definition display is a key technology for clear display and accurate prediction of equipment such as spaceships and space shuttles; at the same time, rail transportation, large airports, outdoor scenic spots and other fields place an urgent demand on high-end lighting. Ultra-thin optical devices with polymer microstructures are the core technology to solve the above problems, and the key lies in the efficient manufacture of light guide plates with microstructures. After years of research, the project team has achieved the following innovative results:
(1) Proposed new technology of injection and rolling forming. For the first time, combining the forming technologies by injection of polymer materials and rolling of sheet metal, innovatively introduced the new technology of polymer injection and rolling forming, which solved the technical bottleneck, the difficulties to process with low efficiency in manufacturing light guide plates with large-area microstructures in China.
(2) Proposed the design and manufacture technology of injection and rolling nozzle for uniform velocity, and developed equipment for injection and rolling, which completely change China's situation of lacking original technology and products on high-end polymer ultra-thin optical devices with microstructures.
(3) Proposed a new method for predicting errors on ultra-precision single point diamond (roll microstructure) turning (SPDT), realizing accurate prediction of workpiece microstructure machining errors.
The project's expert authentication and third-party testing indicate that achievements of the project are technically difficult and innovative, and the proposed injection and rolling forming technology on polymer light guide plate with microstructure has reached the internationally advanced level as a whole.
