Description
Technical field
The present invention relates to a kind of production line of light guide plate, refer to especially a kind of on the plastic material film hot roll extrusion the micropore groove is arranged, the light guide plate production line that output in the unit interval can significantly be promoted.
Background technology
Because LCD is not the display device of self-luminosity, therefore need utilize an external light source to reach the effect of demonstration, as backlight module (Backlight Module) is exactly the technology of institute's widespread use among the LCD, and light guide plate is important assembly in the backlight module, it mainly is to be used for guiding the transmission direction of sending light beam, penetrates to convert line source or pointolite to area source again.
And the making mode of production of existing at present slimming light guide plate, mainly be after utilizing Jet forming machine earlier plastic molting to be become approximate liquid state, in-mold molding reinjects, make light guide plate can be made into required shape, and can be covered with the microstructure micropore groove that majority is arranged on the surface, reach the purpose of diffusion light to utilize these microstructures; But finish this process, need to make earlier a mould (Mold), carry out simultaneously after the required microstructure of simulate optical assembly (Pattern) is manufactured in die (Core orStamper) and goes up, be bumped into (insert) mould (Mold) assembling again, and mould is installed (SetMold) penetrating on the board, also need earlier plastics be dehumidified before the installation, oven dry, softening process waited processing in 6～8 hours, just can send into the production storage vat that penetrates board, and then beginning is with high temperature melting plastic grain, inject in the mould with high pressure again, treat its typing, open mould and take out plastic, and after pruning its sprue, just can finish product, so processing procedure is suitable loaded down with trivial details, tediously long, and can't be lifted at output in the unit interval, make the production cost can be higher relatively, moreover, if in the time of will penetrating the light guide plate of big specification, be can be because the plastics of fusing are difficult to by average filling with in die cavity, and will increase the difficulty of making, and when the plastics that melt by ejection formation and when cooling off, will have the up Texturized significantly misgivings of thin light guide panel.
So promptly in view of this inventor is to think and the idea of creation, satisfy with for many years experience and designed, through inquiring into and study specimen test in many ways, and repeatedly revise improvement, be to release the present invention.
The technical matters point that desire solves:
Existing light guide plate is to make in the mode that penetrates, so not only processing procedure is loaded down with trivial details, tediously long, can't be lifted at the output in the unit interval, more because plastics are difficult to by average filling with in die cavity, and will increase the difficulty of making big specification light guide plate, this is the technical matters point that desire solves.
Summary of the invention
The object of the invention provides a kind of production line of light guide plate, is to make in the mode that penetrates to overcome existing light guide plate, processing procedure loaded down with trivial details, tediously long, can't be lifted at the defective of output in the unit interval.
The production line of light guide plate of the present invention, its plastic material film is the conveying via tension control system, and moved forward, the operation process more in regular turn through overheated roll extrusion and metallic film, leveling, cooling, overlay film, processing procedure such as cut, can finish the moulding of light guide plate, wherein, tension control system is a delivery wheel, it mainly is to be used for driving the plastic material film to advance, with with hot roll extrusion, leveling, cooling, overlay film, processing procedure such as cut and continue into the flow process moving-wire of consistentization, and can be used for driving light guide plate output after the moulding, hot roll extrusion is to carry out between first roller and second roller, the thickness of gap that two rollers are separated by and visual plastic material film adjusts, and inside is to produce thermal source is arranged, metallic film is that the required microstructure of first simulate optical assembly is made light shield before processing procedure carries out, light shield also cooperates etched mode, and produce the intaglio plate master mold of microstructure, utilize electroforming to make a metallic film intaglio plate master mold again, make metallic film can cooperate the intaglio plate master mold, and on its outer peripheral face, be formed with most dimpling points, leveling is to be one group with two leveling wheels, this two leveling wheel and on, stagger down and the thickness of visual plastic material film adjusts, and inside is to produce thermal source is arranged, cooling is the temperature that is used for reducing the plastic material film surface, to avoid the plastic material film that the phenomenon of thermal deformation takes place in successive process, overlay film is to be pasted with a transparent protective film in plastic material film both side surface, prevent that according to this plastic material film is contaminated, cut is on utilizing, bed die cuts into required size with the light guide plate that molds, shape, and cut before carrying out is to utilize one can the plastic material film be tightened toward the idle pulley that supports to arrive in that covers displacement again, temporarily blockaded because of course when preventing to cut, and cause the distortion of plastic material film extrusion by mould; By this, be the production line that can constitute this light guide plate.
Effect against existing technologies:
One, the production line of light guide plate of the present invention, the mode that it utilizes hot roll extrusion produces light guide plate, is to have simple and easy, the advantage rapidly of processing procedure, so can significantly be lifted at the output in the unit interval, makes production cost reduction person relatively.
Two, the production line of light guide plate of the present invention, it utilizes the mode of hot roll extrusion, will more not be subjected to the restriction of light guide plate specification, and can reduce many unnecessary puzzlements.
Three, the production line of light guide plate of the present invention and since the plastic material film only the surface be heated, softening, after Gu Dangqi rolled out, hardening by cooling rapidly can prevent the phenomenon of thermal deformation relatively.
Four, the production line of light guide plate of the present invention, the flow process of its consistentization of production line tool is so that can effectively utilize space and personnel's allotment, significantly to promote the inter-industry competition advantage.
