1. a kind of production technology of light guide plate incidence surface optical microstructures, which is characterized in that it includes the following steps:

  • (1) light guide plate incidence surface forming part mold insert is processed.(2) precision CNC and its backman required for the optical microstructures of production light guide plate incidence surface forming part mold insert are carried outThe preparation of tool;

    A, prepare the accurate CNC especially restructured, precision installs special knife up to micron level in the Z-direction of CNCTool seat and process tool, the base of tool and process tool can be moved up and down with Z-direction.B, the base of tool and process tool are adjusted to working condition, allows the point of a knife of the process tool and the work of the CNCAfter table top 2 is vertical, the Z axis of the base of tool and process tool in processing with accurate CNC is dynamic according to requiring.C, a precision vice is placed on the work top 2 of the CNC.(3) by the light guide plate incidence surface forming part mold insert clamping on precision vice, correct the light guide plate incidence surface atThe forming surface of type part mold insert is vertical with Z axis, controls the flatness of the forming surface of the light guide plate incidence surface forming part mold insertAt 2 μ

    m or less.(4) by adjusting light guide plate incidence surface forming part mold insert, so that the forming surface of light guide plate incidence surface forming part mold insertIt is orthogonal state with cutter, then tightens precision vice and clamp the light guide plate incidence surface forming part mold insert.(5) processing program is finished according to design requirement, workbench is mobile by XY axis sequence, and CNC machining center is cooperated to make to processCutter is mobile to process optical microstructures in Z-direction.(6) after processing is completed according to the machined parameters of setting, to the light in the forming surface of light guide plate incidence surface forming part mold insertMicro-structure is learned to be cleaned.
