Description
Technical field
The invention belongs to printing technology, relate in particular to a kind of liquid crystal LGP reticulate pattern hot stamping roller.
Background technology
Mainly contain 3 kinds of LGP printing technologies now: a. ejection forming technique.This technology mainly is used on the small-medium size, below 23.6 cun.B. screen printing technique.This technology mainly is used in more than 15 cun, needs printing-ink, and the fraction defective height after the moulding, can not be repaiied again, scrappage height, the highest the reaching about 40% of LED LGP printing scrappage.C. laser-engraving technique.This technical costs is low, and the site is good, and speed is too slow, is not suitable for producing.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of liquid crystal LGP reticulate pattern hot stamping roller, is intended to solve the scrappage height that exists in the present LGP printing technology, and ink printing contaminated environment, speed of production wait the problem of shortcoming slowly.
The embodiment of the invention is achieved in that a kind of liquid crystal LGP reticulate pattern hot stamping roller, and this roller comprises quartz pushrod, high temperature resistant bearing, heavy wall quartz ampoule, site, semiconductor heating rete;
Described high temperature resistant bearing is installed in the two ends of described quartz pushrod, and described heavy wall quartz ampoule is installed on the described quartz pushrod, and described heavy wall quartz ampoule inside is equipped with described semiconductor heating rete, and described heavy wall quartz ampoule surface is provided with salient point.
The LCD backlight light guide plate mesh point of liquid crystal LGP reticulate pattern hot stamping roller provided by the invention has no longer needed ink printing, printed dimensions can be infinitely great, infinitely small, scrappage can be reduced in 1%, defective products can be repaired again, and dirty can the cleaning thoroughly solves present LGP printing technology scrappage height, shortcomings such as ink printing contaminated environment, processing cost also significantly reduces at least 40% simultaneously.Contact with the LGP face because roller is a line above the external diameter all the time,, also do not need baking or ultraviolet illumination simultaneously so error of curvature can be controlled in 0.2%, one-shot forming, simple to operate.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1,2 shows the structure of the liquid crystal LGP reticulate pattern hot stamping roller that the embodiment of the invention provides.For convenience of explanation, only show the part relevant with the embodiment of the invention.
This liquid crystal LGP reticulate pattern hot stamping roller comprises quartz pushrod 1, high temperature resistant bearing 2, heavy wall quartz ampoule 3, site 4, semiconductor heating rete 5.
High temperature resistant bearing 2 is installed in the two ends of quartz pushrod 1, and heavy wall quartz ampoule 3 is installed on the quartz pushrod 1, and there is semiconductor heating rete 5 heavy wall quartz ampoule 3 inside, and there is site 4 on heavy wall quartz ampoule 3 surfaces.
Site 4 can be set to concave point or salient point.It is exactly concave point that salient point is imprinted on the LGP surface, after doing blasting treatment at bump surface, the vestige (particle of sandblast is a spherical shape) of blasting treatment is just arranged in the formed concave point in LGP surface; If the position of salient point is made concave point into, just form salient point on the LGP surface like this.Because the particle diameter of sandblast is littler tens times than the diameter of former salient point or concave point, so just form vaporific on the surface of original salient point or concave point.
Heavy wall quartz ampoule 3 wall thickness must surpass 5mm, and blasting treatment is carried out on the surface, carve the salient point reticulate pattern, and salient point 4 degree of depth are controlled at about 0.5mm.
Heavy wall quartz ampoule 3 inwalls plate the semiconductor heating film with vacuum coating method, form semiconductor heating rete 5, measured power behind the plated film, and the surface temperature uniformity, electric heating conversion efficiency be 96%, the transformation efficiency height;
Quartz pushrod 1 two ends engraving groove 6, as conductive trough usefulness, the structure of quartz pushrod 1 as shown in Figure 3.
Heavy wall quartz ampoule 3 and quartz pushrod 1 combination, (promptly use machining center (CNC) to carve a round recessed 6 on bakelite, diameter of a circle is the same with the quartz ampoule external diameter to look for concentric circles.Hole of engraving in the middle of groove 6, it is the same with quartz pushrod 1 that the hole gets diameter.Like this heavy wall quartz ampoule 3 is placed in the round recessed 6, quartz pushrod 1 is placed in the circular hole, so just can make heavy wall quartz ampoule 3, and quartz pushrod 1 is on the same center of circle.After carrying out, at heavy wall quartz ampoule 3, quartz pushrod is fixed with high-temp glue between 1 space, and glue is high temperature resistant more than 300 °);
Put high temperature resistant bearing 2 on quartz pushrod 1, quartz pushrod 1 bearings at both ends must be equidistant with the position of putting with heavy wall quartz ampoule 3 two ends with the position of point, and the inwall of high temperature resistant bearing 2 can not contact with electrode in the conductive trough);
The use of this liquid crystal LGP reticulate pattern hot stamping roller is: at first, look for a lucite that cuts (PMMA) LGP, tear the diaphragm on surface off, set level.The voltage of direct current 24V, be added on the electrode of conductive trough, control electric current with attemperating unit, wait surperficial salient point 4 temperature of heavy wall quartz ampoule 3 to reach 200 °.The surface of LGP must be with heavy wall quartz ampoule 3 surperficial vertical, the edge of LGP must be vertical with the external diameter of heavy wall quartz ampoule 3.Control device well, heavy wall quartz ampoule 3 is rolled across fast on the surface of LGP, concrete speed can be adjusted (this can use Electric Machine Control), so just can print off the reticulate pattern of salient point 4 on the LGP surface, because by blasting treatment, there is numerous little concave point on salient point 4 surfaces above the salient point 4, so just the salient point 4 in the surperficial generation of LGP has countless hemispheric salient points 4, in the time of above light is got to hemisphere, light just has been scattered.Because the LGP surface all is a minute surface,,, can on device, add upward pressure as DeGrain so just lean on the weight of device self just such effect can have been produced substantially.High temperature resistant bearing 2 is fixed on the guide rail, and standing part is isolated high temperature resistant bearing 2 and guide rail with bakelite, prevents that like this heat waste is at guide rail.
The direct effect of the embodiment of the invention is: energy-conservation, and environmental protection, the efficient height, cost is low.The LCD backlight light guide plate mesh point has no longer needed ink printing, printed dimensions can be infinitely great, infinitely small, scrappage can be reduced in 1%, defective products can be repaired again, and dirty can the cleaning thoroughly solves present LGP printing technology scrappage height, shortcomings such as ink printing contaminated environment, processing cost also significantly reduces at least 40% simultaneously.Contact with the LGP face because roller is a line above the external diameter all the time,, also do not need baking or ultraviolet illumination simultaneously so error of curvature can be controlled in 0.2%, one-shot forming, simple to operate.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
