Meanwhile, as illustrated in FIGS. 11 and 12, the position adjusting unit C3-6 ′ according to another embodiment of the present invention is illustrated in FIGS.

A plate-like board C3-61 having a correction protrusion C3-64 corresponding to the groove 104 formed at the bottom of the jig 100, and a connecting plate C3-612 having an inclined long hole formed on the bottom surface thereof. );

An upper plate member C3-654 having a bearing C3-652 coupled to the inclined long hole C3-613 of the board C3-61 is formed at an upper portion thereof, and a lower portion of the upper plate member C3-654 is formed at an upper portion thereof. An operating table C3-65 connected to the rail groove formed at the bottom thereof;

A rail member (C3-66) formed at the base (C3-67) to couple the rail groove of the operating table (C3-65) to guide the lateral movement;

A servo motor (not shown) that exerts power to move the operating table (C3-65);

It is formed on the other side of the base (C3-67) is configured to include a lifting guide bar (C3-68) connected to the board (C3-61) to support the lifting operation.

Therefore, the operation of the position adjusting unit (C3-6 ') according to another embodiment is the operating table (C3-65) is moved in the transverse direction along the rail member (C3-66) using a servo motor, in conjunction with the inclined long hole The plate-shaped board C3-61 on which the bearings C3-652 are installed is moved along the direction C3-613 and thus moves in the 휭 direction.

Accordingly, the connecting plate C3-612 having the inclined long hole C3-613 is raised or lowered, and the board C3-61 subordinate thereto is operated to be raised or lowered.

Hereinafter, the operation of the present invention will be described.

The empty jig 100 is transported by the first loader C1-2 of the first transport device C1 and moved in the lateral direction.

The jig 100 carried by the first transport device C1 is seated on the first jig moving device B1 of the first long side frame F-31.

That is, after the jig 100 is placed on the seating plate B1-1 of the first jig moving device B1, the jig 100 is corrected to be placed at the correct position by driving the jig alignment device C3.

After the correction protrusions C3-64 of the position adjusting parts C3-6 and C3-6 'protrude to fit into the grooves 104 of the jig 100 to be fixed, the mounting table B1- is operated by the operation of the driving unit. 2) with 1 pitch.

The movement of the first jig moving device B1 is moved by one pitch so that the jig 100 is positioned at each film supply device F1 to F4.

That is, the diffusion film, the prism film, the prism film, and the diffusion film are sequentially stacked while passing through the first to fifth film supply apparatuses F1 to F5, respectively.

The diffusion film, the prism film, the prism film, and the diffusion film are sequentially positioned on the jig after alignment in the X, Y, and θ directions by the position correction means, thereby enabling accurate positioning.

After the diffusion film, the prism film, the prism film, and the diffusion film are stacked, the inspection device (V) reads whether foreign matter is introduced, and if the foreign matter is present, the lamination film is not laminated and the position of the foreign matter is coordinated. Check it and send it to the next process to solve the cause of the defect and reuse it.

On the other hand, if the diffusion film, the prism film, the prism film, the diffusion film is laminated, and the normal product without the inflow of foreign matter by the inspection device (V) to manufacture a finished product by laminating the light-shielding film and then compressed.

As the jig 100 is sequentially moved to the first to fifth film supply apparatuses F1 to F5, five kinds of films are stacked thereon.

The jig 100 in which the five kinds of films are stacked in this manner is mounted on the second short side frame F-31 by the second jig carrying device C2 after reaching the end position of the first long side frame F-31. It is moved and conveyed to the 2nd jig moving apparatus B2 of the opposite side.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.

B: Cleaner device B1, B2: First and second jig moving device
C1, C2: first and second jig carrying device D: carrying means
