≪
Hereinafter, a first embodiment of the liquid crystal cell adsorption / movement apparatus according to the present invention will be described with reference to Fig.
As shown in Fig. 2, the liquid crystal cell adsorption / transport device BT includes a adsorption pad BT-B10, a vacuum pump BT-P, an intake path BT-G, a horizontal movement means BT- And a vertical movement unit BT-ST. In the present embodiment, the liquid crystal cell adsorption mobile device BT is located above the liquid crystal cell conveying route B.
The absorption pad BT-B10 is a member that makes direct contact with the liquid crystal cell U when the liquid crystal cell adsorption mobile device BT adsorbs the liquid crystal cell U. As shown in Fig. 2, a plurality of adsorption units BT-B20 are disposed on the lower surface of the adsorption pad BT-B10, and the adsorption units BT-B20 face the liquid crystal cell U downward. When not adsorbed, the adsorption pad (BT-B10) is located at a position above the liquid crystal cell conveying path (B) with a certain height. When the liquid crystal cell U is adsorbed, the adsorption pad BT-B10 is lowered by a vertically moving means BT-ST which will be described later, and the adsorbing portion BT-B20 is moved in the liquid crystal cell conveying path B Of the liquid crystal cell (U). In order to prevent damage to the surface of the liquid crystal cell U, the suction unit BT-B20 is preferably a suction nozzle made of an elastic material such as rubber.
3A and 3B are plan views of the absorption pad BT-B10 when viewed from above. As shown in the plan view, the shape of the adsorption pad BT-B10 is a "convex" shape, and the mirror symmetry line L of the "convex" outline corresponds to the direction of liquid crystal cell conveyance in the liquid crystal cell conveying path B .
Preferably, the adsorption pad BT-B10 is disposed such that the base of the convex shape is on the downstream side of the liquid crystal cell conveyance path. By doing so, both the liquid crystal cell carried in the MD direction and the liquid crystal cell transported in the TD direction are fixed relative to each other while referring to the base of the " convex " can do. Therefore, even if the liquid crystal cell is transported in either the MD or the TD direction, the alignment can be performed in the same manner.
Although the adsorbing portion BT-B20 may be arranged in the convex form on the lower surface of the adsorption pad BT-B10, preferably the adsorbing portion BT-B20 is formed of the adsorption pad BT- B10).
As shown in Figs. 3A and 3B, any liquid crystal cell during TD and MD transportation is appropriately adsorbed by the adsorption pad because the adsorbing portion BT-B20 is disposed in the " convex " Thus, the adsorption pad (BT-B10) of the present embodiment can cope with both TD and MD transportation, and the ineffective area proportion is reduced compared to the conventional quadrangular adsorption pad, thereby preventing the apparatus from becoming large.
Further, as shown in Fig. 3, one side on the downstream side in the carrying direction of the adsorbed liquid crystal cell protrudes from one side (in other words, a convex bottom side) on the downstream side in the carrying direction of the adsorption pad. This is because the tip end of the liquid crystal cell is sandwiched between the bonding rollers Ru and Rd in a state where the liquid crystal cell is fixed by suction. The liquid crystal cell can be adhered without displacement by releasing the adsorption with the front end of the liquid crystal cell sandwiched by the rubbing rollers Ru and Rd. In short, in the present invention, the cells may be housed within the contour range of the adsorption pad, but more preferably, the tips of the liquid crystal cells may be slightly projected and fixed by suction.
A well-known product may be used as long as the vacuum pump BT-P generates negative pressure for adsorbing the liquid crystal cell U.
The intake passage BT-G is provided with a main intake passage BT-G10 and a plurality of sub intake passages BT-G20 in communication with the vacuum pump BT-P and the adsorption section BT-B20 have. One end of the main intake passage BT-G10 communicates with the vacuum pump BT-P and the other end of the main intake passage BT-G10 branches into a plurality of sub intake air intake conduits BT-G20, (BT-B20) in the BT-B10. Further, each of the sub intake air conduits BT-G20 may also be branched into a plurality of capillary intake air passages, and may communicate with the suction portions BT-B20 via the capillary intake passages.
2, a main valve BT-V10 is provided in the main intake passage BT-G10 and a sub valve BT-V20 is provided in each of the sub intake valves BT-G20 . The main valve BT-V10 and the sub-valves BT-V20 can be independently opened and closed. Opening and closing the main valve BT-V10 communicates or blocks the adsorption pad BT-B10 as a whole with the vacuum pump BT-P. In addition, when the main valve BT-V10 is opened, the sub valve BT-V20 is selectively opened and closed to actually open and close the sub valve BT-V20 in the region where the adsorption portion BT- The area for generating the attraction force can be flexibly adjusted. For example, in the case shown in Fig. 3A, the sub intake air conduction BT (B0) along the adsorption portion BT-B20 in the projected region (in other words, the region other than the liquid crystal cell U) on the left side of the drawing of the adsorption pad BT- -G20 are blocked by the respective sub-valves (BT-V20), and no attraction force is generated in the region. In the case shown in Fig. 3B, for example, in the sub-intake (BT-B10) along the adsorbing portion BT-B20 in the protruding regions (in other words, the region other than the liquid crystal cell U) The BT-G20 is blocked by each of the sub-valves BT-V20, and no attraction force is generated in the region.

The horizontal moving means BT-HT may be a robot arm driven by another well-known structure, for example, an electric motor. The movement in the horizontal direction may be merely a movement along the liquid crystal cell conveying direction or may be a movement in a plane in which the movement along the liquid crystal cell conveying direction and the movement along the direction perpendicular to the liquid crystal cell conveying direction are combined as necessary.
The up-and-down moving means BT-ST moves the adsorption pad BT-B10 in the vertical direction. The up-and-down moving means BT-ST includes a guide sleeve BT-ST10 installed along the vertical direction, and a slide bar BT-ST20 slideable along the guide sleeve BT-ST10 .
The vertical moving means BT-ST may be of another well-known structure like the horizontal moving means BT-HT. The up-and-down moving means BT-ST is connected to the horizontal moving means BT-HT and cooperates to move the adsorption pad BT-B10 in the space.

The horizontal moving means BT-HT may appropriately adjust the position on the horizontal plane of the adsorption pad BT-B10 as necessary, before or during the descent. Then, by opening the main valve BT-V10 and selectively opening the sub valve BT-V20, an attraction force is generated in the attracting portion BT-B20 that is in contact with the upper surface of the liquid crystal cell U And the liquid crystal cell U is subjected to adsorption.

Then, as shown in Fig. 4D, when the optical film attaching portion detects that the leading end of the liquid crystal cell U is aligned at the joining operation start position by a sensor (not shown), the two film application rollers Ru and Rd And the tip of the liquid crystal cell U is placed together with one end of the optical film F stretched from the peeling means SP shown in Fig. 4B. Thus, the tip of the optical film (F) is bonded to the tip of the lower surface of the liquid crystal cell (U).
Subsequently, as shown in Fig. 4E, the main valve BT-V10 is closed to release the adsorption of the adsorbing portion BT-B20. Then, the up-and-down moving means BT-ST is driven to raise the adsorption pad BT-B10 to move away from the upper surface of the liquid crystal cell U.
Subsequently, as shown in Fig. 4F, the horizontal shifting means BT-HT is driven to move the adsorption pad BT-B10 back to the starting position shown in Fig. 4A.
