In the manufacturing process of optical film, optical film can be transmitted through many deflector rolls in different processing units,
For example, optical film through deflector roll in treatment trough, drying unit, enter material unit, stripping unit, be bonded unit, cut unit
Transmitted Deng between.However, the situation that optical film has position deviation during manufacture and transmission occurs, light may be caused
Film is learned to deviate predetermined transmitting path, snake movement or cause optical film end fold etc..In addition, it is light polarizing film in optical film
Example in, light polarizing film after the treatment trough processing procedure such as Peng Run, dyeing, extension, washing, when being dried into drying oven can because
High temperature and produce contraction, thus cause film surface to offset, even the situation of end reflexed.
The roller (guide) apron that this exposure embodiment provides suitably increases optical film by adjusting the coefficient of friction of deflector roll end
Side and the active force of deflector roll, optical film can be slowed down and occur to skid skew in transmit process or crawl mobile situation, and
Also optical film can be slowed down high-temperature process after-contraction is mobile or the problem of reflexed.In addition, the deflector roll that this exposure embodiment provides
Device can coordinate the width of optical film, position of the element that adjustment prevention optical film is offset on roller (guide) apron, suitable for various
The optical film material of different size and type.
The roller (guide) apron of this exposure offer is provided.Fig. 1 is shown to be disclosed in some embodiments according to this, deflector roll
The schematic perspective view of device 100.As shown in figure 1, roller (guide) apron 100 includes deflector roll main body 10, deflector roll main body 10 can have first
The end 10a and the second end 10b relative with first end 10a.The material of deflector roll main body 10 includes polymeric material, metal material
Material, other suitable materials or foregoing combination.For example, polymeric material can include rubber or urethane etc., gold
Belong to material can include steel, chromium or tungsten, titanium, aluminium, etc..In one embodiment, the material of deflector roll main body 10 can be stainless steel or rubber.
In addition, roller (guide) apron 100 includes at least one separable part 12, be in Fig. 1 by taking two separable parts 12 as an example, can
Separation member 12 may be disposed at the first end 10a or the second end 10b of deflector roll main body 10, and be surrounded in deflector roll main body 10.Value
It is noted that the traveling of separable 12 bootable optical film of part, and prevent optical film is skidded on roller (guide) apron 100 offset or
It is snake movement.
Fig. 2 shows that this is disclosed in some embodiments, and roller (guide) apron 100 transmits the upper schematic diagram of optical film 13.As Fig. 1~
Shown in Fig. 2, in certain embodiments, separable part 12 may be disposed at the position of the end of deflector roll main body 10.Specifically, can divide
Off member 12 according to the breadth W4 adjustment positions of optical film 13, can make the widthwise edges area vertical with conveying direction X of optical film 13
Domain 13e can be placed in the separable top of part 12, and directly be contacted with the separable part 12 of part.In other words, separating part 12 is
Can be according to the moving element of the breadth adjustment position of optical film.
In certain embodiments, scope of the coefficient of friction of part 12 0.2 to 0.8 is separated, preferably 0.25 to 0.5
Scope.In certain embodiments, scope of the coefficient of friction of foregoing deflector roll main body 10 0.05 to 0.2, preferably 0.1 to 0.15
Scope.In addition, in certain embodiments, the coefficient of friction of separable part 12 differs with the coefficient of friction of deflector roll main body 10
0.15 to 0.6, preferably 0.15 to 0.45 scope.Especially, separating the coefficient of friction of part 12 need to control in suitable model
In enclosing, if the coefficient of friction of separable part 12 is too small, possibly it can not effectively prevent optical film 13 in skew thereon；Instead
It, may scratch or damage optical film 13 if the coefficient of friction of separable part 12 is excessive.Similarly, separate part 12 with
The coefficient of friction difference of deflector roll main body 10 also needs control to make the edge 13e positions of optical film 13 in coefficient of friction in suitable scope
Relatively high region, with effectively slow down the edge 13e of light polarizing film 13 because process temperatures rise and caused by shrink and reflexed.
Furthermore in certain embodiments, the thickness of separable part 12 preferably exists in 0.05mm (millimeter) to 1mm scope
0.1mm to 0.5mm scope.Especially, separating the thickness of part 12 need to control in suitable scope, if separable part 12
Thickness is excessively thin, then possibly can not effectively prevent optical film 13 in skew thereon；If the conversely, thickness mistake of separable part 12
Thickness, then the edge 13e of optical film 13 may be caused to produce fold or the situation of fracture because of difference in height.
In certain embodiments, the width W1 for separating part 12 can be in 25mm to 100mm scope, preferably in 50mm extremely
75mm scope.In certain embodiments, the width W1 of separable part 12 accounts for the 1% to 6% of the width W2 of the deflector roll main body 10.
In certain embodiments, for example, the width W4 of the breadth of optical film 13 can be between 1450mm to 2250mm.Optics
The width W3 that film 13 is covered on separable part 12 is about the 0.5% to 5% of the overall width W4 of optical film 13, preferably
1% to 2.5%, or the width W3 that optical film 13 is covered on separable part 12 can be between 10mm to 80mm, preferably 20mm
To 60mm.
Especially, optical film 13 need to be controlled in suitable scope in the width on separable part 12, in some embodiments
In, the width W3 that optical film 13 is covered on separable part 12 accounts for the 20% to 80% of the width W1 of separable part 12, preferably
For 40% to 60%.If optical film 13 is too small in the width on separable part 12, possibly can not produce enough active forces with
The effectively skew of prevention optical film 13；Conversely, if optical film 13 is excessive in the width on separable part 12, light may be increased
Film 13 is learned to be rubbed by separable part 12 and produce dysgenic risk.Brought forward is stated, it will be understood that, art has
The visual practical application of usual skill, according to the width of the separable part 12 of the breadth of optical film 13 suitably adjustment, make optical film 13
Width on separable part 12 is in foregoing suitable scope.
