Description of the Invention: [Technical Field of the Invention] The present invention relates to a "light guide plate production line", and more particularly to a hot-rolled microporous groove on a plastic material film, so that the output per unit time can be greatly increased. Improved light guide plate production line. [Prior Art] Since the LCD is not a self-luminous display device, it is necessary to use an external light source to achieve the display effect. For example, a backlight module is a technology widely used in LCDs, and a light guide plate is a backlight. An important component of the 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 0. Currently, the conventional production method of the thinned light guide plate is mainly utilized. The injection molding machine first melts the plastic into a liquid state, and then injects it into the mold to form the light guide plate into a desired shape, and the surface thereof can be filled with a plurality of microstructures (microporous grooves). To use these microstructures to achieve the purpose of diffusing light; but to complete the process, a mold (Mold) must be fabricated, and the microstructure required to simulate the optical component is fabricated on a Core or Stamper. After that, insert the mold (Mold) assembly and install the mold on the injection machine. Before installation, the plastic must be dehumidified and dried. Softening (process 6~8 hours) and other treatments can be sent to the production storage tank of the machine, and then the plastic pellets are melted at high temperature, and then injected into the mold with high pressure. 200932499 After the mold is set, the mold is opened and the plastic parts are removed. After the trimming port is trimmed, the production can be completed. Therefore, the process system is quite versatile and lengthy, and it is impossible to increase the output per unit time. The production cost will be relatively high. Moreover, if a large-sized light guide plate is to be fired, it will be difficult to dissolve the plastic. It is averaged to fill the cavity, which will increase the difficulty of making, and when the secret Wei Wei (4) is dissolved, there will be concerns about her large curling deformation. In this case, the inventor of the present invention has the idea of thinking and creating, and has been designed with many years of experience. The invention has been developed through a variety of discussions and trials of sample tests, as well as many revisions and improvements. SUMMARY OF THE INVENTION Technical problems to be solved: Conventional light guide plates are made by injection, so that not only the process is glazed, it is too long, and the production in the unit cannot be increased, and the plastic is difficult to be filled on average. In the cavity, 0 will increase the difficulty of making a large-size light guide plate, which is a technical problem to be considered. Technical features for solving the problem: The production line of the light guide plate of the present invention, the 郷(4) thin crane is conveyed through the tension control system' _ before the miscellaneous operation, and in the process of operation, the metal film is thinned, leveled, cooled, and covered. The film, cutting and other processes can complete the forming of the light guide plate. The tension control system is the conveying wheel, which is mainly used to drive the plastic film to advance, to heat, level, cool, and cover the film. The cutting process and other processes continue to be a consistent process line, 200932499 and can be used to drive the output of the light guide plate after forming, the hot roll is carried out between the first roller and the second roller, and the gap between the two rollers is visible and the plastic material is visible. The thickness of the film is adjusted, and the internal system generates a heat source. The metal film is used to simulate the microstructure of the optical component before the process is performed, and the reticle of the reticle is formed into a reticle to form a concave matrix of the microstructure. The mold 'make the gravure master mold by electroforming to form a metal film, so that the metal film can match the gravure master mold, and the recorded micro-bumps are formed on the outer circumference ©, and the flat-panel two-flat wheel is 0 group, the two flat wheels are up and down staggered and can be adjusted according to the thickness of the plastic material film, and the internal system generates a heat source, and the cooling is the temperature of the thin wire surface of the silk-reducing rubber material to avoid the plastic impurity film. In the case of the money-shaped phenomenon in the back Lai towel, Lai attaches a transparent protective enamel on both sides of the plastic film to prevent the plastic film from being contaminated. The cutting system uses the upper and lower molds to form the guide. The light plate is cut into the required size and shape, and the plastic material film is tightly stretched by a movable displacement to the idler wheel to prevent the film from being temporarily blocked by the mold during the cutting. This causes the plastic material to be deformed by the squeezing of the film; thereby, it can constitute the production line of the light guide plate. Compared with the effects of the prior art: (1) The production line of the light guide plate of the present invention uses the method of hot rolling to manufacture the light guide plate, which has the advantages of simple and rapid process, and thus can be greatly improved in unit time. Production, which makes the production cost relatively lower. (2) The production line of the light guide plate of the present invention, which utilizes the method of hot rolling, is less limited by the size of the light guide plate, and can reduce many unnecessary troubles. (3) The production line of the light guide plate of the present invention is relatively cool and hardened by the fact that the surface of the plastic film is only heated by the surface and softened by 200932499, so that the phenomenon of thermal deformation can be prevented relatively. (8) The birth of this guide is hidden, and its birth tool—Wei Cheng Cheng can effectively use the deployment of space and personnel to greatly enhance the competitive advantage of the industry. [Implementation] The examiner’s purpose, characteristics and efficacy of the invention can For further understanding and understanding, please refer to the following [simplified description of the drawings] as follows: Generally, according to the present invention, the first picture is matched with the second one, and the plastic material film (Light Guide) FilmXlO) is transported through the tension control system (2〇), and it has been run before. In the course of operation, it is subjected to hot rolling (3〇), metal film (4〇), leveling (50), cooling. (60), film (70), cutting (80) and other processes, the light guide plate (90) can be formed; wherein, the tension control system (20) is the transport wheel 'which is mainly used to drive the plastic film (1〇) Ο Advance to continue the process of hot rolling (30), leveling (50), cooling (60), laminating (7〇), cutting (8〇) into a consistent process line And can be used to drive the light guide plate (9〇) output after molding, hot rolling (30) is attached to the first roller (31) and the second Between the wheels (32), the gap between the two rollers is adjusted by the thickness of the plastic film (10), and the internal heat source is generated; the metal film (40) is required to simulate the optical components before the process is performed. The microstructure is made into a photomask. The photomask is etched to form a microstructured concave mother plate 200932499, and the gravure master is electroformed to form a metal film (40) to make a metal film (40). A plurality of micro-bumps (41) can be formed on the outer peripheral surface thereof with the gravure master mold'; the flattening (50) is a set of two flat wheels (51), and the two flat wheels (51) The upper and lower parts are staggered and the thickness of the plastic material film (10) is adjusted, and the internal system generates a heat source; the cooling (60) is used to reduce the temperature of the surface of the plastic material film (1〇) to avoid the plastic film. (10) The phenomenon of thermal deformation occurs in the post-production process; 0 The film (7〇) is attached with a transparent protective film on both sides of the plastic film (10) to prevent contamination of the plastic film (10). ; cutting (80) uses the upper and lower molds to cut the formed light guide plate (9〇) In the required size and shape, and cutting (80), the front cover is re-applied with a movable displacement abutting wheel (81) to tighten the plastic film (1 inch) to prevent cutting ( 8〇) When the travel route is temporarily blocked by the mold, the plastic film (1〇) is pressed and deformed. The above-mentioned light guide plate production line 'the metal film (40) is wrapped around the first roller (31) (please view the first figure together with the third figure), and adjust the two roller gaps and temperature Then, the plastic material film (10) is transported through the tension control system (20), and the plastic material film (10) can pass between the first and second rollers (31) (32) to utilize the first roller (31). The generated heat source softens the surface of the plastic material film (1 〇) opposite to the first roller (31), and when the plastic material film (10) passes between the two rollers, the metal film (40) can be utilized. The micro-bump (41) is rolled on the surface of the plastic material film (1〇), and the micro-hole groove (11) is rolled out, and after it is completely passed, the tie-up wheel (51) is stretched. It can prevent the phenomenon of thermal deformation from curling up in the clock, and because the surface of the plastic film (10) is rolled, 200932499 is covered with a large number of micro-holes (11) 'When the plastic film (10) is cut (80) When the required size is removed and applied to the backlight module to become the light guide plate (90), one side surface can be utilized. The micro-hole (11) is used to achieve the purpose of diffusing light. Continued, as shown in the fourth figure, 'the metal film (40) can also be wrapped on the first and second rollers (31) (32) to utilize the inside of the first and second rollers (31) (32). The generated heat source simultaneously softens the two surfaces of the plastic film (10) so that the plastic film (1〇) can be rolled on both surfaces when passing between the first and second rollers (31) (32). It is covered with a large number of micro-holes (11). Therefore, when the plastic film (ίο) is applied to the backlight module to become the light guide plate (90), it can be double-sided. In addition, the order of density and arrangement of the micro-holes (11) can be changed with the pattern design of the light-grain and etching, and the first and second rollers (31) (32) and metal The film (40) and the flattening wheel (51) can be scaled with the plastic film (1 inch), and accordingly, the light guide plate of the appropriate size (9 inches) can be directly hot rolled. 〇The above-mentioned light guide plate production line has the following advantages: (1) It uses the method of hot rolling (30) to manufacture the light guide plate (90), which has the advantages of simple and rapid process, so it can be greatly Increase the production per unit time and make the production cost relatively lower; (2) The method of using hot rolling (30) will be less restricted by the size of the light guide plate (9〇), and can reduce many unnecessary (3) Because the plastic film (1〇) only heats and softens the surface, when it is rolled out, it can be quickly cooled and hardened, which can prevent the phenomenon of thermal deformation. (4) Its production line With a consistent process, we can effectively use the deployment of space and personnel to significantly enhance the competitive advantage of the industry. 200932499 The above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto; that is, the equal variation and modification of the scope of the patent application of the present invention should still be The scope of the creation of the patent is covered. 〇 ❹ 11 200932499 [Simple description of the drawings] The first figure is a flow chart of the operation of the present invention for hot rolling a micro-groove on one side surface of a plastic material film.
