Description
Technical field:
The present invention relates to light guide plate manufacturing technology field, be specifically related to a kind of device of straight literary style production edge-type light guide plate.
Background technology:
Light guide plate is to utilize acryl/PC sheet material of optical grade, then, with having high reflectivity and the hitech materials of extinction not, stamps light guiding points in the acryl sheet material bottom surface of optical grade with UV screen printing technology.The light that utilizes optical grade acryl sheet material to draw to send from lamp is in the stop on optical grade acryl sheet material surface, and in the time that light is mapped to each light guiding points, reflected light can be toward all angles diffusion, then destroys conditioned reflex and penetrates by light guide plate is positive.By various density, light guiding points not of uniform size, can make light guide plate uniformly light-emitting.The purposes of reflector plate is that the light that bottom surface is exposed is reflected back in light guide plate, is used for improving the service efficiency of light.
1, serigraphy light guide plate
First carry out film web plate, web plate is positioned on the acrylic board cleaning up, employing is sprayed on film web plate with the ink of reflectorized material, then scrape back and forth several times on film web plate with scraper plate after, film plate is uncovered, ink point is just printed on acrylic board, then acrylic board is dried in the ultraviolet baking oven of high temperature.The problem of printing light guide plate is: 1, ink easily comes off.2, ink printing environmental pollution is serious, is difficult to pass through environmental protection tests.3, thin type light guide plate is carried out easily jaundice variable color and distortion after high-temperature baking, 4, ultraviolet high temperature baking oven power consumption more than a myriawatt, resource consumption is serious.
2, hot-pressing light guide plate, or be referred to as hot roll extrusion light guide plate
First manufacture the master mold of a set of light-conducting board mold, mould is pole shape, has the overshooting shape site designing on mould, and mould inside is generated heat with resistance wire, makes mould produce high temperature.By the roll extrusion one time on the acrylic board cleaning up of pole shape mould, the site of mould upper process shape rolls out the pit of same site at acrylic board, complete the manufacture of light guide plate.The problem of hot-pressing light guide plate is: 1, reappearance is too poor, and the degree of depth that site rolls out is inconsistent, causes yield too low.2, cannot production large-size light-conducting plate, 3, manufacture roll extrusion master mold complex process, yield rate is low.
3, injection molding light guide plate
The light-conducting board mold of carrying out site is contained on injection machine, and injection machine sucks the plastic grains of acrylic board and after high temperature melting, injects mould, and after quick cooling, the demoulding is light guide plate of moulding out.This type of light guide plate yield rate is high, but is subject to the restriction of injection machine tonnage, cannot accomplish more than 32 cun size light guide plate,
4, laser engraving light guide plate
Adopt 10.6um wavelength laser directly carries out single-point irradiation on acrylic board, acrylic board Yin Gaowen and gasifying.By position and the direction of XY axle or galvanometer control Ear Mucosa Treated by He Ne Laser Irradiation, form point-like pit on surface, complete light guide plate manufacture.1, laser engraving, because being subject to laser stability restriction, cannot ensure reappearance, is only applied to the light guide plate manufacture of light fixture and advertising lamp box at present, cannot be applied to display, the high-end light guide plate manufacture such as TV.2, different material difference, the light guide plate luminance that causes Laser Processing to go out is variant.
Summary of the invention:
The object of this invention is to provide a kind of straight literary style and produce the device of edge-type light guide plate, it improves light guide plate luminance, solve current ink printing light guide plate because of environmental pollution be difficult to by detect, and cause a large amount of light guide plate cannot export problem, and prior art cannot machining large-sized thin type light guide plate problem, improve light guide plate production efficiency.
