Abstract

PURPOSE:To make it possible to accurately position a liquid crystal panel by arranging a positioning air cylinder and a press air cylinder so as to generate rotatory power and again correcting shift by the generated rotatory power. CONSTITUTION:When the liquid crystal panel 1 is mounted on a loading plate 2 without being inclined, the liquid crystal panel 1 can be positioned without generating problem. When the panel 1 is mounted on the plate 2 in an inclined state, in two sets of the Y-direction positioning mechanisms arranged on the plate 2, two positioning air cylinders 5a, 5b and two press air cylinders 5c, 5d are arranged in X-direction and a positioning air cylinder 5e and a press air cylinder 5f opposed each other generate couples of forces in the opposite direction with respect to the acting points of the respective forces of both cylinders. The opposite couple of forces becomes the rotatory power in the opposite direction with respect to the panel 1 and only the other couple of forces acts because the panel 1 is inclined and, therefore, the panel 1 is rotated regardless of frictional resistance and angle shift is corrected and the loading plate 2 is accurately positioned.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention
Since the surface of is necessary for focusing on the inspection optical system 4,
It is extremely flat and smooth. On the other hand, the large-sized liquid crystal panel 1 has a large thickness d as described above despite its large area.
Since it is thin, when it is placed on the placing plate 2, it adheres to it,
A considerable frictional resistance occurs between the two. Now, assuming that the liquid crystal panel 1 is placed with an angle deviation with respect to the XY directions, the liquid crystal panel 1 does not move due to this frictional resistance, and therefore the angle deviation is not corrected. This point will be described with reference to FIG. In FIG. 5, it is assumed that the liquid crystal panel 1 is placed while tilting to the right. First, when the positioning air cylinders 5a, 5b, 5e are operated, the tips of the pressing rods 51 stop at the positioning positions. Then the pressing air cylinder 5c, 5d, the operation of 5f, the liquid crystal panel 1 moves the point p c, p d, p f is pressed, the point p
The a and p e come into contact with the pressing rod 51 and stop. However, since the frictional resistance is large, the liquid crystal panel 1 does not rotate, so that the action points p b are separated from each other in the illustrated state. That is, the angle deviation δθ is not corrected. The above is the case where the liquid crystal panel 1 is tilted to the right side, but when the liquid crystal panel 1 is tilted to the left side, the angle deviation is not corrected as in the above case. It is generally known that when it is difficult to move an object having frictional resistance only by a straight-ahead force, the object can be easily moved by using a rotating force together with the straight-ahead force. On the other hand, the positioning air cylinders 5a and 5b and the pressing air cylinder 5 facing them
Since c and 5d are on the same lines of action C 1 and C 2 , respectively, there is no rotational force on the liquid crystal panel 1. Therefore, it is considered that if the liquid crystal panel 1 is rotated by imparting a rotational force to these, the angular deviation can be corrected. The present invention has been made on the basis of the above idea. The positioning air cylinder and the pressing air cylinder are arranged so that a rotational force is generated, and the generated rotational force corrects the angular deviation to correct the liquid crystal panel 1. An object is to provide a positioning mechanism that can perform positioning.

In the above positioning mechanism, the positioning and pressing action of each positioning air cylinder and the pressing air cylinder is the same as the conventional one. However, when the liquid crystal panel is mounted with an inclination with respect to the mounting plate, the two sets of Y-direction positioning mechanisms disposed on the mounting plate have two positioning air cylinders and two pressing air cylinders. The air cylinders are arranged at appropriate intervals in the X direction, and the positioning air cylinders and the pressing air cylinders facing each other generate couples in opposite directions with respect to the action points of the respective forces. This opposite couple is a rotating force in the opposite direction to the liquid crystal panel, but since the liquid crystal panel is inclined, only one couple acts, so the liquid crystal panel rotates regardless of the frictional resistance, and the angle The misalignment is corrected and the plate is correctly positioned on the mounting plate.

The positioning operation of the liquid crystal panel 1 by the positioning mechanism 5'will be described below. First, when the liquid crystal panel 1 is mounted on the mounting plate 2 without being inclined, the liquid crystal panel 1 is positioned without any problem as described with reference to FIG. However, when it is placed at an angle, the angular deviation is corrected and the positioning is performed correctly. This correction method will be described in some detail with reference to FIG. FIG. 2 (a) shows a case where the liquid crystal panel 1 is placed while being inclined to the right side with respect to the placing plate 2, and even if each air cylinder is operated, an angular deviation δθ remains,
It is assumed that only the action point p b 'is separated (same as in FIG. 5). The pressing force of the air cylinder 5c When F c Now,
A reaction force F a with respect to the pressing force F c is generated in the air cylinder 5a which is in contact with the action point p a ′. Since both the air cylinder is arranged at a position opposite at an interval L X relative to the line of action C 1, distance L X by the pressing force F c and the reaction force F a
Proportional to couple M L is generated, which action line C 1 and C 3
Becomes the rotational force with respect to the intersection point O 13 . Due to this rotational force, the liquid crystal panel 1 rotates counterclockwise about the intersection O 13 and the angular deviation δθ is corrected. In this case, since the left side of the positioning air cylinder 5b is not in contact with the p b 'acting point, the reaction force against the pressing force F d of the pressing air cylinder 5d F
c is not generated, and therefore a couple is not generated and no rotating action is performed. On the other hand, FIG. 2 (b) shows the case where the liquid crystal panel 1 is placed while being inclined to the left side with respect to the placing plate 2, and in this case, the positioning air cylinder 5a comes into contact with the action point p a '. Since a couple is not generated, a couple M R is generated by the pressing force F d of the air cylinder 5 d and the reaction force F b of the air cylinder 5 b, and the liquid crystal panel 1 is centered on the center point O 23. Rotate clockwise to correct the angle deviation. With the above corrections, the liquid crystal panel 1 is properly positioned with respect to the mounting plate 2 regardless of the large frictional resistance, regardless of whether the liquid crystal panel 1 is mounted on the right side or the left side. Note that the above interval L X
Is determined by a trial experiment, but it has been confirmed that L x of about 10 mm is suitable for a large-sized liquid crystal panel of the above size. Further, it is obvious that the positioning mechanism 5'is not limited to the large-sized liquid crystal panel 1 and can be applied to other plate-like objects similar to this.

1. An X mounted on a mounting plate of an inspection stage.
A large-sized rectangular liquid crystal panel having two long sides in the Y direction and two short sides in the Y direction is positioned by a positioning mechanism to perform an inspection, and one of the two long sides is placed on the surface of the mounting plate. Two positioning air cylinders for positioning,
Two pressing air cylinders that press the other of the two long sides are arranged at appropriate intervals in the X direction, and the positioning air cylinders and the pressing air cylinders that face each other act on the points of action of the respective forces. And two sets of Y-direction positioning mechanisms that generate couples opposite to each other and one of the two short sides are positioned 1
A large-sized liquid crystal panel, characterized in that a plurality of positioning air cylinders and a set of X-direction positioning mechanisms composed of one pressing air cylinder that presses the other of the two short sides are arranged. Positioning mechanism.
