Composite light guide plate substrate hot extrusion shaping equipment and machining method thereof

Abstract

The invention discloses composite light guide plate substrate hot extrusion shaping equipment and a machining method thereof. The composite light guide plate substrate hot extrusion shaping equipmentcomprises a feed device, an extrusion heat preservation mold, a light guide plate substrate extrusion device, a transfer table, a detecting device and a cutting device; one end of the extrusion heat preservation mold is connected with the feed device, and the other end of the extrusion heat preservation mold is connected with the light guide plate substrate extrusion device; the light guide platesubstrate extrusion device is connected with the transfer table; the detecting device is arranged above the transfer table; the cutting device is arranged on the rear side of the detecting device; thefeed device comprises a first feed hopper, a second feed hopper, a third feed hopper, a first feed pipe, a second feed pipe and a third feed pipe; the extrusion heat preservation mold comprises a heat preservation mold, a first extrusion groove, a second extrusion groove and a third extrusion groove; and the light guide plate substrate extrusion device comprises a structural roll shaft, a mirrorroll shaft and a shaping roll shaft. The light guide plate substrate hot extrusion shaping equipment has the characteristics of diffusion and prism effects and being free of cooperation of a diffusionfilm and a prism film.

Description

technical field [0001] The invention relates to a composite light guide plate substrate hot extrusion molding equipment and a processing method thereof, in particular to a composite light guide plate substrate hot extrusion molding equipment with diffusion and prism effects, without the need for a diffusion film and a prism film, and a processing method thereof . Background technique [0002] With the advancement of social science and technology, the requirements for display products are getting higher and higher; the existing equipment technology cannot meet the higher technical requirements. In order to reduce the cost, weight and complexity of backlight assembly, the diffusion required in the backlight module The function, prism function and light guide function are integrated on the optical original plate used for the light guide plate substrate to improve the yield rate of the backlight module and reduce the thickness of the backlight module. The surface of the mirror ...

AI Technical Summary

Problems solved by technology

[0003] Extrusion lines currently on the market can only squeeze light boards and structural boards. The top angle of the structural boards is 100-130°, and the light-gathering effect is relatively poor.

Existing extrusion line, the extruded raw materials are processed into light guide plate substrates and assembled into backlights. Diffusion film and prism film are still required, otherwise it is difficult to meet the optical specifications

In the process of thinning the display control panel, the diffusion film and prism film in the backlight module not only increase the thickness and weight, but also increase the cost accordingly
