| 摘要 |
The present invention relates to an extruding-type apparatus for manufacturing a light guide plate capable of patterning according to various models by transferring patterns of different shapes on the surface without exchanging rolls. The apparatus for manufacturing an optical member of the present invention comprises an extrusion part of melting thermoplastic resin, and discharging an optical sheet through an outlet on one side; multiple polishing rolls installed on the back end of the extrusion part, and forming the discharged optical sheet; and a pattern roll assembly composed of a rotatable central shaft, multiple support shafts radially connected to the central shaft, and multiple pattern rolls coupled with the end of the support shafts by roll rotation shafts, and installed on the back end of the polishing rolls to transfer a pattern to the surface of the optical sheet. |
