The present invention relates to a kind of friction roller that uses in the manufacturing process of liquid crystal indicator and friction (rubbing) device of friction treatment is carried out to the alignment films on substrate.
Background technology
In liquid crystal indicator, between 2 glass substrates, be provided with liquid crystal layer, the inside surface of 2 glass substrates be formed respectively for liquid crystal layer apply electric field transparency electrode, for open, close electric field on-off element, for the color filter of colour display screen and the alignment films etc. for carrying out orientation to liquid crystal molecule.Alignment films is made up of the resin bed of the polyimide be coated on substrate etc., after alignment films solidification, utilizes rubbing device to carry out friction treatment to this alignment films, thus along prescribed direction aligned liquid-crystal molecule.
Rubbing device has friction roller, makes this friction roller above the platform loading, be fixed with glass substrate, rotatably support the two ends of this friction roller, utilizes double sticky tape etc. to be wound on the surface of friction roller by nylon loop (friction cloth).While make friction roller rotate, make this fluffing part with the surface contact of the alignment films on glass substrate and to rub this surface along constant direction, thus carrying out friction treatment.Japanese Unexamined Patent Publication 2004-302093 publication discloses an example of this kind of rubbing device.As shown in Figure 5, the rubbing device 110 disclosed in Japanese Unexamined Patent Publication 2004-302093 publication has the framework 115 of the door shape to arrange across the mode of platform 111, and friction roller 112 is rotatably bearing on framework 115.Framework 115 possesses: the lift component 118 of コ font, and it is lifting freely arranged along facing medial surface 115a; Cylinder body, preferably cylinder 116, it makes lift component 118 be elevated along vertical axis (Z axis).Friction roller 112 is bearing on lift component 118 by bearing 113a, 113b.Framework 115 is provided with drive motor 17, utilizes the transfer device (not shown) be made up of band and belt wheel being configured in the inside of framework 115 to drive friction roller 112 to carry out rotating (the 0012nd section with reference to Japanese Unexamined Patent Publication 2004-302093 publication) with the rotational speed expected, sense of rotation.
About friction treatment, this friction treatment (biased friction process) is carried out obliquely with arbitrary angle (rubbing angle) in the direction that the turning axle of friction roller such as can be made orthogonal relative to the bearing of trend or throughput direction (MD direction) with glass substrate.Rubbing angle is set to predetermined angular, be preferably set to the angle in the angular range of-45 ~+45 °, by such setting, uniform state of orientation can be formed in alignment films, suppress the deterioration of picture display, striped inequality, thus the higher image quality of liquid crystal display can be realized.As the method for setting rubbing angle, have and make the method that friction roller tilts relative to the glass substrate on platform, the method etc. that glass substrate is tilted relative to friction roller.When making friction roller rub obliquely relative to glass substrate, relative to the relative transfer velocity between glass substrate and friction roller, the rotational speed of friction roller is very big, and therefore frictional direction is the direction roughly consistent with the sense of rotation of friction roller.
In friction treatment, sometimes improve rubbing intensity (frictional strength), friction treatment speed and utilize many friction rollers to process to seek.Fig. 6 represents 2 friction rollers 125 being supported on framework 123 on platform 120, but the friction roller of more than 3 also can be utilized to process.When utilizing many friction rollers to process, many friction rollers configure in parallel with each other, and are set to the rubbing angle of regulation.Illustrated 2 friction rollers 125 are rotatably bearing on lift component (not shown), and this lift component is lifting freely arranged along the facing medial surface 124a of framework 123.Not shown glass substrate is configured in the top of friction roller 125, while make friction roller 125 rotate, while make the fluffing part on this friction roller 125 and the surface contact of the alignment films of glass substrate, glass substrate is moved in the horizontal direction relative to friction roller 125, thus carries out friction treatment.
