New Description: [New Technology Field] This creation is about a "manufacturing device for light guide plates", especially a kind of micro-hole groove hot-rolled on a plastic film to allow the output per unit time. A greatly improved manufacturing device. [Prior Art] Since the LCD is not a self-luminous display device, it is necessary to use an external light source to achieve the effect of display, such as a backlight module (Backlight Mule) is a widely used technology in the LCD, and the light guide plate It is an important component in the backlight module, which is mainly used to guide the transmission direction of the emitted light beam to convert the line light source or the point light source into a surface light source and then emit it. At present, the conventional production method of thin-type light guide plate is mainly to use the injection molding machine to melt the plastic into a liquid state, and then re-inject the mold into the mold, so that the light guide plate can be made into a shape required by the household, and The surface will be covered with a large number of microstructures (micropore grooves) to use these microstructures to achieve the purpose of diffusing light; however, to complete the process, a mold (M〇id) needs to be fabricated first. The microstructure required for the analog optics is fabricated on a mold (c〇re 〇r Stamper), then assembled into an insert mold (M〇ld), and the mold is mounted (8 Μ〇ι) On the shooting machine, before the installation, the plastic must be dehumidified, dried, softened (process 6~8 hours), etc., in order to give people (four) the machine's raw Zhao barrel, and then open the high temperature melted Na The granules are injected into the mold at a high pressure. After the mold is set, the mold is opened, the plastic parts are removed, and the injection port is trimmed, the product can be completed, so the process system is rather cumbersome and lengthy, and the production in a unit time cannot be improved. Making production costs relatively high, and then If a large-size light guide plate is to be shot, it will be difficult to fill the mold cavity because the molten plastic is not evenly filled, which will increase the difficulty of making M334344, and when the molten plastic is shot and cooled. At the time, there will be concerns about the large-scale curling of the thin light guide plate. It is based on the 'how to deal with the shortcomings of the above-mentioned conventional light-guided production methods'. In view of this, the creator is thinking about the idea of creation and creation, and has been designed with many years of experience. After many discussions and trials of sample tests and multiple revisions and improvements, this creation was launched. [New content] * To be solved Technical problems: The conventional light guide plate is made by injection, so not only the process is cumbersome, it is too long, and it cannot be improved. In the unit time, the output is more difficult to be flattened, and it will be filled in the cavity. It is difficult to make a large-size light guide plate by one port. This is the technical problem to be solved. Technical Features for Solving the Problem·············································· The optical element of the silk is made of the required microstructure, the reticle is formed, and the reticle is matched with the side to make the micro-structured concave master mold, and then the concave mother mold is electro-formed into a metal-type _, so that the gold ship is matched with the gravure The mother pulls ', and the recorded micro-bumps are formed on the outer peripheral surface thereof, so that the metal film can be wrapped outside the roller group to complete the process of the hot plastic material film, and then cut and cut by the cutting (punching) The required size can be used to manufacture a light guide plate with a micro-groove on the surface. The metal film is wrapped in the roller of the roller set, and the turn-over wheel is replaced with a button. The plastic material class _ bribe 轮崎赵 mirror, to soften the surface, and when the film of the material passes through the two rollers, the micro-bump on the metal film can be turned on the surface of the plastic film M334344. The hole groove, when it is completely through, will be cooled and hardened by the plastic film only surface heating, so as to prevent thermal deformation, and because the negative film surface of the plastic material is rolled and covered. There are many micro-hole slots, so when plastic The material film is cut and used to cut the required size, and is applied to the backlight module, so that when the light plate is used, the microporous groove can be used to make the diffusion wire, thereby The manufacture of light panels. Compared with the effects of the prior art: • (1) This _ provides the manufacturing equipment of the county board, and the method of manufacturing the light guide plate by means of hot rolling is a simple and rapid process, so it can be greatly improved in unit time. Yield 'is a relatively low cost of production. (1) This creation provides a manufacturing device for a light guide plate, which utilizes hot rolling to be less restricted to the size of the light guide plate, and can reduce many unnecessary troubles. (3) This creation provides a manufacturing device for a light guide plate. Since the surface of the plastic material film is only heated, _softened, it can be rapidly cooled and hardened when it is rolled out, and the phenomenon of thermal deformation can be prevented relatively. [Embodiment] In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Examples of the drawings] for detailed explanations. As shown in the first, second, and third figures, the process is performed before the micro-structure required to simulate the optical component is made into a photomask (Ph〇t〇mask), and the photomask is etched. The micro-structured gravure master is fabricated, and the gravure master is electroformed to have a thin metal film (M334344 film α〇), so that the metal film can be matched with the gravure master mold, and the outer peripheral surface thereof is formed. Most of the micro-bumps (11), so that the metal film (10) can be wrapped outside the roller set (2〇) to complete the process of hot-rolling the Light Guide Film (30), and then By cutting (punching) the required size, a light guide plate having a surface covered with a microgroove (31) can be manufactured. The 'metal film (10) is wrapped around the first roller (21) of the roller set (20), and after adjusting the gap between the two rollers and the temperature, the plastic film (3〇) is placed, and the plastic film is used. 3〇) can use the heat source generated in the first roller (21) to soften the surface opposite to the first roller (2), and when the plastic film (30) passes between the two rollers, the metal film can be utilized. (1〇) on the micro-bump (11) and the micro-hole (31) is rolled on the surface of the plastic film (3〇). After it is completely passed, it will be due to the plastic film (30). ) only the surface is heated, and it can be cooled and hardened rapidly, so as to prevent thermal deformation, and because the surface of the plastic film (30) is rolled and covered with a large number of micro-holes (31), The plastic film (30) is cut and removed by the cutting and punching, and applied to the backlight module to become a light guide plate, and the micro-hole groove (31) on one side surface can be used for diffusion. The purpose of the light. Continued from the fourth picture with the fifth picture, the metal film (1〇) can also be wrapped on the first and second rollers (21) (22) of the roller set (20) to take advantage of the first And a heat source generated inside the two rollers (21) (22) to simultaneously soften the two surfaces of the plastic film (30) so that the plastic film (10)) passes between the first and second rollers (21) (22). It can be rolled on both surfaces and covered with a large number of micro-holes (31). Therefore, when the plastic film (3〇) is applied to the backlight module to become a light guide plate, it can be double-sided. Light. In addition, the order of the density and arrangement of the micro-holes (31) can be changed according to the design of the pattern M334344 during the mask and etching, and the first and second rollers (21) (22) and The metal film (1〇) can be scaled with the plastic film (30), so that the light guide plate of the appropriate size can be directly hot rolled. By the structure of the above specific embodiment, the following benefits can be obtained: (1) The method of manufacturing the light guide plate by means of hot rolling is advantageous in that it is easy to manufacture and quick, so it can be greatly improved. The production time in the production period will reduce the number of people in the production county; (2) the method of using hot rolling, • will be less restricted by the size of the county board, and can reduce many unnecessary troubles; Since the surface of the plastic material film (10) is only softened by heat, when it is rolled out, it can be rapidly cooled and hardened, and the phenomenon of thermal deformation can be prevented relatively. ~ In summary, this creation has indeed achieved a breakthrough structural design, and the improved creation of the inner valley 'at the same time can achieve industrial use and progress, and this creation is not seen in any publication, but also novelty When complying with the provisions of the relevant laws and regulations of the Patent Law, Ai loves to file a new type of patent application in accordance with the law, and asks the fishing bureau review committee to grant legal patent rights. ·: Only the above-mentioned ones are only a preferred embodiment of this creation.
