Description
Technical field
The present invention relates to the method and the device of the end face of flat-sheet materials such as machining plastics, particularly when having cut the end face of flat-sheet material, can be concatenated to form the cutting working method and the device of the flat-sheet material end face of micro concavo-convex at the length direction of end face.
Technical background
In the prior art,, shown in the exploded perspective view of Fig. 8, adopt end face irradiation profile light supply apparatus as one of backlight assembly of liquid crystal indicator.In this end face irradiation profile light supply apparatus, side at the LGP 1 that forms by polymethyl methyl esters (PMMA) etc., the bar-shaped light source 2 of configuration and one end face cold-cathode tube in opposite directions etc., at the one side side of LGP 1 (below side) configuration reflector plate 3, and stackedly disposing prism sheet 4 and diffusion sheet 5 respectively in another side side (upper face side), is that roughly semicircular reflecting plate (リ Off レ Network ) 6 surrounds the rear side of bar-shaped light source 2 with section shape.LGP 1 is made like this: utilize the injection moulding of resins such as PMMA, make the Plastic Flat sheet material of flat wedge shape, the end face of a side this flat-sheet material, that area is big is cut, shape and be the light inlet end face.In the end face irradiation profile light supply apparatus of this structure, illumination light from bar-shaped light source 2 ejaculations, with the inside of the reverberation that utilizes reflecting plate 6 from the surface feeding sputtering of LGP 1 to LGP 1, shown in the side view of Fig. 9, while reflect, reflect and spread in the inside of LGP 1 and each boundary face of each sheet material 3,4,5.Illumination light after the diffusion penetrates from the surface of diffusion sheet 5, from the back side one side irradiating liquid crystal display unit of liquid crystal indicator.Among Fig. 9, mark 7,8 is formed in pip and the prism formation portion on the LGP 1 respectively.
The problem of such end face irradiation profile light supply apparatus is, on the exiting surface of LGP 1, the regional z apart from about light source side end face 5mm～6mm compares deepening with other zone, has produced the luminance nonuniformity that is called " blanking bar ".Producing reason as it can enumerate, and the illumination light that penetrates from bar-shaped light source 2 during light inlet end face by LGP 1, diminishes in the anaclasis angle near the position of light inlet end face, is not easy to cause the light diffusion.In order to address this problem, proposed to carry out exasperate and handled (マ Star ト processings) by end face to the flat-sheet material that becomes LGP, promote the method that the light at the light inlet end face of LGP 1 spreads.This exasperate is handled, and is to be undertaken by the methods such as injection processing of using ceramic powders etc.
In addition, at the end face of flat-sheet material, being concatenated to form section by the length direction at end face is leg-of-mutton projection, also can promote the light diffusion (for example seeing the flat 11-231320 communique of Japanese Patent Application Laid-Open) of the light inlet end of LGP 1.
As one of method that on the end face of flat-sheet material, forms continuous projection, cutting working method is arranged, for example, superhard slotting cutter is installed on the Milling Process machine, transfer the end face of machining flat-sheet material with extremely low speed.In addition, as the method beyond the cutting working method, for example can adopt the resin molding method that uses metal die.
But the injection processing by using ceramic powders etc. etc. is carried out exasperate when handling, and because of the degree of its exasperate, can cause the briliancy of the exiting surface integral body of LGP to reduce.For this reason, according to certain research report,, be recommended in the scope of 0.05 μ m～0.3 μ m according to the arithmetic average roughness Ra of JIS B0031-1994 defined.But this regulation only is the arithmetic mean of instantaneous value of the difference of the high end of peak valley between reference region in the roughness curve, and the peak valley in not meaning that between reference region is with certain difference of height equal distribution.Therefore, use this method for treating end face, be difficult to reproduce identical briliancy balance, in other words, be difficult to the repeatability that the exasperate result is guaranteed on high level ground.Like this, adopt to spray the exasperate processing method of processing etc., be not easy the end face as the flat-sheet material of LGP efficiently and in heterogeneity is processed into the matsurface of the light diffusion shape with modest size.
In addition, forming on the end face that utilizes machining at flat-sheet material in the method for continuous projection, generally be to adopt slotting cutter with a plurality of blades, but because the grinding state difference of blade, the distance from the slotting cutter pivot to the cutting face of each blade is difference a little, so, on machined surface, produce undesirable striped sometimes.On the other hand, when adopting the slotting cutter of hilted broadsword sword, though can not produce the inhomogeneous of the machining state that causes by blade,, because the quantity of blade is few, thus the time of processing to grow.In addition, as shown in figure 10, slotting cutter (its track is shown in double dot dash line t) is moved on one side towards direction shown in the arrow D, cut the end face of flat-sheet material 9a on one side, when on the end face of flat-sheet material 9a, forming continuous peak valley 9b, because the processing machine intrinsic mechanicalness defective relevant with the feeding of slotting cutter produces inhomogeneous sometimes on the spacing p of peak valley 9b.Like this, promptly use cutting working method before, the also very difficult end face that will become the flat-sheet material of LGP evenly and efficiently is processed into required shape.
In addition, adopt in the resin molding method of metal die, for with the exiting surface reflecting surface in opposite directions of LGP 1 on, form a plurality of pips (reflection De Star ト) 7 of light diffusion usefulness, on roughly rectangular light inlet end face with respect to this reflecting surface, also to have the shape of light diffusion usefulness, then in the die cavity of the metal die that in this ester moulding, adopts, produce fine incision (ア Application ダ one カ Star ト).Therefore, to carry out the pushing tow action firmly capablely, perhaps having to adopt the cavity surface that forms this light inlet end face is the metal die of side slide form, used resin material is the PMMA material in the making of LGP, be crisp firmly and the resin material of good fluidity, so, the fine shape segmental defect can be caused, perhaps resin flows into the gap of sliding-type cavity segment, produces the new problem of resin burr.In addition, the size of said here peak valley shape or waveform shape requires highly to be number μ m, spacing is 10 μ m～20 μ m, so, in the processing of the cavity part of the metal die that when ester moulding, adopts, need the equipment of high-caliber process technology and high price, and need more process time.Therefore, the metal die price increases, and the cost of LGP product also increases.
