Figure 12 a, 12b are problems when adhering to light polarizing film on liquid crystal cell substrate according to former mode for explanation Diagrammatic illustration.
The diagrammatic illustration of the former technology illustrated in Figure 12 a, 12b is to illustrate the former liquid crystal cell base for illustrating in Figure 5 The figure of the problem actually occurred in the engineering for adhering to light polarizing film on plate.
As shown in Figure 12 a, 12b, in the fixed light polarizing film 2 in setting table 2A of former absorption, it is exposed at outside setting table 2A The part in portion, can not maintain as shown in Figure 5 the smooth shape of a straight line, there are in fact problem inclined towards side.
As it appears from the above, due to the problem for the part outside setting table 2A being exposed in light polarizing film 2 upward or lower section bends, Therefore the light polarizing film 2 of the sweep can not be completely close to liquid crystal cell substrate 1, so as in light polarizing film 2 and liquid crystal cell base Bubble is produced between plate 1, causes the problem that substandard product occurs.
Also, according to the mode of former attachment light polarizing film, light polarizing film 2 is adsorbed lighter in setting table 2A, is now removed Roller 5 is sent to rotate, and liquid crystal cell substrate 1 is attached to the light polarizing film 2 on liquid crystal cell substrate 1 with end, is moved by the direction of arrow Power, and there is tensile stress on the whole in light polarizing film 2, so as to light polarizing film 2 is also elongated, and due to the light polarizing film 2 elongated Length, the entire length of the light polarizing film 2 of elongation is slightly longer than the length of the liquid crystal cell substrate 1 to be adhered to, as a result upper to cause liquid The problem that crystal cell substrate 1 bends.
Figure 13 be for overcoming attachment light polarizing film mode former shown in Figure 12 a, 12b in the feature of present invention of problem carry out The explanatory diagram of explanation.
With reference to Figure 13, light polarizing film attachment device of the invention, the tilting roller 20 for moving up and down with defend tenaciously set position In the fixing roller 22 put, the adhesion sheet 30 of crawler-type mobile is set.
In the state of liquid crystal cell substrate of the invention 1 is to adsorb on conveyance plate 40, the court together with conveyance plate 40 Direction of arrow movement, and the light polarizing film 2 being arranged on liquid crystal cell substrate 1 is placed on above adhesion sheet 30, the court of tilting roller 20 Upper inclination, so that in the state of the end in the corner of light polarizing film 2 contacts with the end in the corner of liquid crystal cell substrate 1, with conveyance Plate 40 is moved with liquid crystal cell substrate 40 towards the direction of arrow, sticks to the light polarizing film 2 on adhesion sheet 30, due to tilting roller 20 gradually Rotation and press liquid crystal cell substrate 1, so as to the remainder of light polarizing film is also gradually bonded with liquid crystal cell substrate 1.
Tilting roller of the invention 20 does not use the driving means such as motor with fixing roller 22, and adopts no-power way.
On the face to be adhered to of the liquid crystal cell substrate 1 for sticking to light polarizing film 2 above adhesion sheet 30, binding agent is smeared, Therefore the liquid crystal cell substrate 1 being attached on panel tote plate 40 is moved towards the direction of arrow, and motorless tilting roller 20 with it is solid Fixed roll 22 also and then rotates.
If tilting roller 20 is rotated with fixing roller 22 by the driving means for arranging in addition, then only with the shifting of conveyance plate 40 Dynamic speed and tilting roller 20 and the rotary speed accurate synchronization of fixing roller 22, just will not adhere to light polarizing film in liquid crystal cell substrate 1 Shi Fasheng light polarizing films 2 elongate or bend it is bad.If but have at all uncoordinated, light polarizing film 2 is adhered on liquid crystal cell substrate 1 The probability of Shi Fasheng substandard products increases.
For this reason, tilting roller of the invention 20 and fixing roller 22 are unpowered.
Also, when light polarizing film 2 is attached on liquid crystal cell substrate 22 in the present invention, the length picture of light polarizing film 2 will not occur The same problem somewhat elongated of technology in the past, therefore there is no the bending of liquid crystal cell substrate 1.When light polarizing film 2 is gradually adhered to When on liquid crystal cell substrate 1, tilting roller 20 rotates towards the direction that liquid crystal cell substrate 1 is moved, therefore adhesion sheet 30 and liquid crystal The translational speed same speed of device substrate 1 is moved, therefore tensile stress does not occur completely in light polarizing film 2.
Recently colour liquid crystal display device is more and more large-scale, and colour liquid crystal display device size in the past is mainly 15 inches, 30 inches, 45 inches are primarily now used, later the size of colour liquid crystal display device also will persistently maximize.
As above, referring to the drawings the embodiment of middle diagram illustrates the present invention, but this is simply illustrated, logical with the art The people of Chang Zhishi, all can understand can carry out accordingly various deformation and equivalent integers.Therefore the real protection domain of the present invention Depending on should be according to claims.
