Description

  The present invention relates to a sticking apparatus for positioning and sticking flat articles such as a liquid crystal panel and a polarizing film in a liquid crystal cell via an adhesive layer provided on one surface.

  In general, a liquid crystal cell used for a display of a small electronic device such as a notebook computer, a car navigation device, a mobile phone, or a portable information terminal has a polarizing film (on the surface of a liquid crystal panel in which a liquid crystal material is sealed between transparent substrates. A polarizing plate) is attached. As a means for adhering this polarizing film to the surface of the liquid crystal panel, the liquid crystal panel is adsorbed and held on one adsorption table, and the polarizing film with an adhesive layer is adsorbed and held on the non-adhesive surface side on the other adsorption table. Place the suction table close to each other so that the liquid crystal panel holding the suction table and the polarizing film face each other, and press the front end overhanging part of the polarizing film against the surface of the liquid crystal panel via the application roller, and slide one of the suction tables in this state. A method is known in which the entire polarizing film is adhered to the surface of a liquid crystal panel by moving the pasting roller in a pressed state by moving it (Patent Documents 1 and 2).

  Thus, when sticking a polarizing film to a liquid crystal panel, in order to ensure high quality as a liquid crystal cell, it is necessary to set both sticking positions with high precision. Conventionally, for the setting of the sticking position, an XYθ table that can be precisely controlled in the front-rear and left-right directions is used on both sides of the suction table for sucking and holding the liquid crystal panel and the polarizing film. At the stage where the panel or polarizing film is placed, while observing the placement state with a camera, the position is adjusted to the front, back, left and right on the XYθ table, so that it is sucked and held in a correctly positioned state and sent to the attachment site. (For example, paragraph 0016 of Patent Document 3 and FIG. 4).

Is placed with the adhesive surface facing upward, the front end of the polarizing film F is brought into contact with the front edge of the positioning plate 13b, so that the front end of the polarizing film F is stretched by a predetermined length from the front end of the slide table 2. It is supposed to be put out.

  In order to produce a liquid crystal cell by adhering the liquid crystal panel P and the polarizing film F with the adhering device having the above configuration, as the liquid crystal panel P and the polarizing film F, an appropriate shape such as a + shape is provided at the corresponding position of the front end portion. The one provided with the alignment marks M1, M2 having a shape is used. In the adhering stage S1, the liquid crystal panel P is first positioned and placed on the reversing table 1 in the placing posture as shown by the solid line in FIG. 3, and the reversing table 1 is held in the state where the liquid crystal panel P is sucked and held. And is fixed by the engagement of the latching concave piece 21 and the latching convex piece 22 and waits. On the other hand, in the film mounting stage S2, the polarizing film F is positioned and mounted on the slide table 2 in a horizontal posture so that the adhesive surface side is upward and the predetermined length of the front end is projected from the front end of the table, The polarizing film F is adsorbed and held. At this time, the height of the slide table 2 is such that the adhesive surface of the polarizing film F is about several mm with respect to the liquid crystal panel P held on the lower surface side of the reversing table 1 according to the thickness of the liquid crystal panel P and the polarizing film F. It sets beforehand so that it may leave | separate at an appropriate space | interval. Further, the slider 10b of the front slide mechanism 10 on which the roller elevating frame 50 and the camera holding frame 60 are mounted is set to the front limit position, and the camera holding frame 60 is arranged to the lowered position.

  Next, the reciprocating base 1 having the polarizing film F sandwiched and held on the slide table 2 as described above is advanced to the sticking stage S1, and the liquid crystal panel is positioned in the field of view of the position reading camera 6 as shown in FIG. The position is stopped at the position where the P alignment mark M1 enters, the position reading camera 6 reads the position of the alignment mark M1, and the two-dimensional coordinates are recorded in the CPU of the controller 7. Then, as shown in FIG. 8B, the reciprocating base 1 is further advanced and stopped at a position where the front end portion where the polarizing film F protrudes is directly below the front end portion of the liquid crystal panel P, and then the slider of the front slide mechanism 10. By moving 10b backward, the alignment mark M2 of the polarizing film F is captured in the visual field of the position reading camera 6 as shown in FIG. 8C, and the position of the alignment mark M2 is adjusted by finely adjusting the XYθ table 3 back and forth and left and right. Is matched with the two-dimensional coordinates of the alignment mark M1 of the recorded liquid crystal panel P within an allowable range. The alignment marks M1 and M2 may be read under illumination by the illuminator 67, and the XYθ table 3 may be finely adjusted while confirming the matching state of the alignment marks M1 and M2 on the camera monitor 25.

  Thus, after aligning both alignment marks M1 and M2, as shown in FIG. 8D, the slider 10b of the front slide mechanism 10 is advanced to position the affixing roller 5 directly below the front end of the polarizing film F and the tilting mechanism. Thus, the slide table 2 is tilted so that the front end side becomes higher. Due to this tilting, the protruding front end of the polarizing film F is close to the surface of the liquid crystal panel P, but is in a non-contact state. Next, the roller raising / lowering frame 50 is raised, and the front end of the polarizing film F is pressed against the surface of the liquid crystal panel P by the attaching roller 5 as shown in FIG. 8E, and then the polarizing film F by the slide table 2 is attached. By releasing the suction and moving the reciprocating base 4 backward in this state, the affixing roller 5 is pressed and rolled as shown in FIG. 8 (f), and finally the entire polarizing film F is attached to the liquid crystal panel P. A liquid crystal cell is prepared by sticking to the surface.

  According to such a sticking device, the position reading by the position reading camera 6 and the fine adjustment by the XYθ table 3 are performed while the polarizing film F is brought to the sticking position with respect to the liquid crystal panel P in standby. Since the sticking operation is performed after aligning the alignment marks M1 and M2 of both P and F, the slide table (suction table) as in the case of precise positioning at the stage of placing on the table as in the past is used. There is no decrease in the adhesion position accuracy due to displacement due to movement and stop, and it can be reliably adhered with a strict accuracy of μm units, thereby providing a high-quality liquid crystal cell.

  Moreover, in this embodiment, since the slide table 2 is tilted by the tilting mechanism 8 and the sticking operation is performed by the sticking roller 5, the surfaces of both flat articles P and F are not prepared on the rear side of the pressing portion of the sticking roller 5. There is no fear of causing poor adhesion due to contact with the film or bubbles entering the adhesion interface, and there is an advantage that a high-quality liquid crystal cell can be manufactured with a high yield. In the embodiment, since the height of the slide table 2 can be adjusted by the lifting mechanism 9, it is possible to cope with the difference in the total thickness of the liquid crystal panel P and the polarizing film F. Furthermore, in the embodiment, since the affixing roller 5 and the position reading camera 6 are moved back and forth by the front slide mechanism 10 provided on the reciprocating base 4, the front and rear positions of the alignment marks M1 and M2 of the liquid crystal panel P and the polarizing film F are set. There is an advantage that the positions of the affixing roller 5 and the position reading camera 6 can be adjusted back and forth in accordance with the change and the difference in the amount of front end protrusion in the polarizing film F.

  The camera holding frame 60 is provided on the reciprocating base 4 in the sticking apparatus of the embodiment, but the alignment mark M1 of the liquid crystal panel P sucked and held by the reversing table 1 on the sticking stage S1 side is in the field of view. It is also possible to provide a fixed position at the entry position or on a slider that moves back and forth.

  In the said embodiment, although liquid crystal panel P and the polarizing film F were illustrated as the 1st and 2nd flat articles mutually bonded, the bonding apparatus of this invention is the bonding of various other panels and films, and a panel. There are no restrictions on the material of the flat article to be attached, such as sticking between films and sticking between films, and the first flat article and the second flat article are pasted via an adhesive layer provided on one of them.
