Description

Technical Field

[0001] The present invention relates to the technical field of light guide plates, and in particular to a light guide plate with a microstructure and processing equipment thereof. Background Art

[0002] A light guide plate with a microstructure is an optical element used to convert a point light source or a line light source into a uniform surface light source. It is widely used in liquid crystal displays, lighting and other fields. The microstructure types include light guide points. Usually, light guide points are printed on the bottom surface of the light guide plate using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The sizes and densities of the light guide points vary. When light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate, thereby achieving uniform luminescence. The microstructure can converge or diverge the light, adjust the propagation path of the light, and make the light better scattered and propagated in the light guide plate, achieving the effect of uniform light output.

[0003] Light guide plates with microstructures mainly work based on the principles of reflection, refraction and scattering of light. Light guide plates are usually made of highly transparent materials such as polymethyl methacrylate (PMMA) or polycarbonate (PC). When light enters the light guide plate from the light source, it propagates through total reflection inside the light guide plate. The role of the microstructure is to destroy this total reflection, causing part of the light to change direction and emit toward the front of the light guide plate. At the same time, by reasonably designing the shape, size, distribution, etc. of the microstructure, the light is evenly distributed on the front of the light guide plate, realizing the function of converting point light source or line light source into a uniform surface light source.

[0004] When using existing light guide plates with microstructures and their processing equipment, the light strips are usually adhered to the side walls of the light guide plates using double-sided tape. However, after fixation, this fixing method does not make the light strips fit tightly against the light guide plates, resulting in unevenness. In addition, gaps and looseness are easily generated and difficult to detect, affecting the fixing effect of the light strips and, in turn, the optical level and preparation quality of the light guide plates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This light guide plate with a microstructure can ensure the efficiency and effect of installation by setting a ring-shaped positioning groove and fixing the light strip in the positioning groove with double-sided tape.

[0017] (2) This light guide plate with microstructure and its processing equipment, by setting up light guide plate preparation equipment, etc., during preparation, when it is necessary to install the light strip, first start the pneumatic suction cup and adsorb the substrate on the pneumatic suction cup in the center, then stick the double-sided tape on the inner side of the light strip, and then wrap it around the positioning groove for pasting, and then, drive the rack to move through the moving module.

Effect, when the rack continues to move, it can push the gear to rotate, so that the rotating plate can be driven to rotate through the third rotating shaft, and then the rotating roller is driven to roll along the side wall of the light strip through the moving mechanism.

After the application is completed, it can be flattened by the rotating roller, and when the rotating fan rotates, the outside air can enter the blowing pipe.

[0018] (3) This type of light guide plate with microstructure and its processing equipment, by setting up a detection mechanism, etc., can scrape and clean the excess glue before the glue is dried by a scraper.

When the second hollow plate 607 moves, the sealing plate 502 can be driven to move through the moving rod 605, so that the circular hole 503 coincides with the glue coating tube 203. At the same time, the first spring 604 is compressed. At this time, the opening The closing mechanism is opened, and under the squeezing action of the gravity plate 202, the glue in the glue storage box 201 can be applied to the glue tube 203 and then smeared between the positioning groove 11 and the light strip 12. After the application is completed, it can be flattened by the rotating roller 20, and when the rotary fan 310 rotates, the external air can enter the blowing pipe 301, and then blown onto the light strip 12 through the heating action of the electric heating ring 303, so as to facilitate the drying of the glue, ensure the installation quality of the light strip 12, and then ensure the optical level and preparation quality of the light guide plate.

[0038] Before the glue dries, the scraper 402 can be used to scrape and clean the excess glue. After scraping, it can be blown dry through the blower tube 301.
