Abstract
The invention relates to an end face thermal transfer printing device for a light guide plate and relates to the field of electronic products. The end face thermal transfer printing device comprises a clamp, the light guide plate, a roller, a rolling shaft and a roller fixing device. The light guide plate is clamped by the clamp and matched with the roller in a contact manner. The rolling shaft penetrates the center of the roller. A heating device is arranged in the rolling shaft. The rolling shaft is fixed to the roller fixing device. By the adoption of the end face thermal transfer printing device, the roller is heated, so that a micro-structure shape on the roller is transferred to the end face of the light guide plate, the incidence angle is increased when LED light passes the end face, with the micro-structure, of the light guide plate, and the HOT Spot phenomenon caused by the large intervals between LEDs is avoided.
Description
Technical field
The invention belongs to electronics field, be specifically related to the hot transfer printing process equipment of a kind of light guide plate end face.
Background technology
Current light guide plate manufacturing technology is mainly divided into: injection moulding, and printing, hot pressing, ink-jet four kinds, wherein only has injection moulding can manufacture section micro-structure light guide plate by the mode of mould, and other three kinds of modes all cannot manufacture.But injection moulding production efficiency is very low, and equipment investment cost is very high, the production cost of light guide plate can not be reduced and enhance productivity.
This equipment and technology can be printing, and the light guide plate of hot pressing and ink-jet provides end face micro-structural, effectively can be reduced the cost of whole backlight by these three kinds of techniques, and improves the production efficiency of light guide plate 3 times.
Another end face processing mode is processing micro structure above rectangular piece of stainless steel at present, by rectangular piece of stainless steel and light guide plate end contact, make microstructure transfer printing on piece of stainless steel on light guide plate, this kind of processing mode is too high to light guide plate flatness requirement, adds man-hour fraction defective too low.The technology of roller processing can overcome this problem.
Summary of the invention
The object of this invention is to provide the hot transfer printing process equipment of a kind of light guide plate end face, by heating roller, the microstructure aspects on it is transferred to light guide plate end face, make LED light increase into angular through the light guide plate end face of band micro-structural, solve because LED spacing causes greatly firefly (HOTSpot) phenomenon.
The technical scheme realizing the object of the invention is: the hot transfer printing process equipment of light guide plate end face, comprise fixture, light guide plate, roller, roller bearing and roller fixing device, fixture accompanies light guide plate, light guide plate contacts with roller and coordinates, roller center is equipped with roller bearing, roller bearing is built-in with heater, and roller bearing is fixed on roller fixing device.
Preferably, described fixture is connected with cylinder.
Preferably, described roller outer peripheral edge is evenly equipped with semicircle micro-structural.
The present invention has positive effect:
(1) roller processing, finished product yield is very high;
(2). technique is simple, easy to operate;
(3). working (machining) efficiency is high, is more than 3 times of current technique.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of fixture of the present invention;
Fig. 3 is the structural representation of the heater of roller of the present invention;
Fig. 4 is roller processing mode schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1-4, the present invention has the hot transfer printing process equipment of light guide plate end face, comprise fixture 1, light guide plate 2, roller 3, roller bearing 4 and roller fixing device 5, fixture 1 accompanies light guide plate 2, light guide plate 2 contacts with roller 3 and coordinates, roller 3 center is equipped with roller bearing 4, and roller bearing 4 is built-in with heater 6, and roller bearing 4 is fixed on roller fixing device 5.
Further, described fixture 1 is connected with cylinder 7.
Further, described roller 3 outer peripheral edge is evenly equipped with semicircle micro-structural.
This detailed description of the invention fixture 1 is promoted by cylinder 7, and fixture 1 presses down and compresses light guide plate 2; Leaded light stretches out 0.3mm-1mm, pushed down by fixture 1, first roller fixing device 5 moves left and right, distance 10mm-40mm is determined when roller fixing device 5 is moved to the left, after roller 3 contacts light guide plate 2, roller fixing device 5 starts movable processing light guide plate 2, and roller 3 only moves once forward or backward; The built-in heater 6 of central roller 4 of roller 3 is used for heating roller 3, and roller 3 is servo-actuated.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
