And at the end of each loading plate is provided with an attachment roller for pressing the polarizing film toward the substrate at the attachment position of the substrate and the polarizing film. That is, since the polarizing film is present on the loading plate rotated at a predetermined angle by the hinge coupling and the loading cylinder, the substrate and the polarizing film is in line contact at the attachment position, and is attached here by the pressure of the attachment roller and the movement of the substrate. This is done.

Hereinafter, only the features of the structure and the operating part according to the modification of the polarizing film supply unit will be described briefly.

First and second polarizing film supply unit is a rotary table (131 ', 161') rotatably installed on the base plate 110; It is disposed vertically in four directions on the rotary tables 131 'and 161' and rotatably installed around the hinges 135 'and 165', and a vacuum suction hole is formed to suck and fix the polarizing film.

According to the modified example of the polarizing film supply unit as described above, the loading plate of the first and second substrate mounting unit and the first and second polarizing film supply unit are located in parallel, the substrate (G) and the polarizing films (F, F) The loading cylinders 134 ', 164' are actuated so that ') is in line contact at the attachment process position. When the loading cylinders 134 ', 164, are operated, the loading plate is rotated about the hinges 135', 165 ', and thus the polarizing film and the substrate mounted on the base plate are inclined at an angle for linear contact. Will be located. Next, the first and second attachment rollers compress the polarizing film toward the substrate, and the substrate mounting unit attaches the polarizing film to the substrate while transferring along the transfer guide rail. In other words, in order to attach the polarizing film to the substrate on one side by applying the present modification, four hinge coupling structures, four loading cylinders, and one attachment roller are required. According to the present modification, the rollers are mounted on each of the loading plates so that only one attachment roller is used, unlike the conventional pressure that the pressure for pressing the polarizing film toward the substrate is not the same. You can get a quality product.

Hereinafter, the operation of the polarizing film attachment device according to a first embodiment of the present invention.

The loading robot 20 proceeds in the transport guide transport direction A to load the substrate G onto the loading plate 122 of the first substrate mounting unit 120. At this time, a vacuum is applied through the vacuum suction hole (H) to adsorb and fix the substrate (G). The rotary table 121 is moved or rotated by the operation of the linear motor 124 and the rotary motor 123 to transfer the substrate G to the first attachment process position.

At the same time, the polarizing film supply unit 30 loads the polarizing film F on the loading plate 132 of the first polarizing film mounting unit 130. Although not shown in the figure, it is preferable to perform adhesive cleaning immediately before loading the polarizing film (F).

The rotary motor 133 transfers the polarizing film F to the first attachment process position while rotating the rotary table 131.

Immediately before the polarizing film F is transferred to the first attachment process position, the protective sheet removing unit 40 removes the protective sheet F1 from the polarizing film F.

Here, the loading plate 132 of the first polarizing film mounting unit 130 maintains the inclined state at a predetermined angle with respect to the first substrate mounting unit 120, so that the rotating motor 133 may rotate the rotating table 131. When rotated by 90 degrees, the substrate G and the polarizing film F are automatically placed at an angle required by the first attaching process.

When the substrate G and the polarizing film F are placed at the first attachment process position, the roller 145 of the first attachment roller unit 140 compresses the polarizing film F, and simultaneously the first substrate. As the mounting unit 120 moves forward in the transport guide rail direction A, the polarizing film F is attached to the substrate G by line contact.

When the first substrate mounting unit 120 reaches a predetermined position, the second substrate mounting unit receives the substrate G having the polarizing film F attached to one side from the first substrate mounting unit 120. .

At this time, in the process of receiving the substrate (G), rather than using a separate moving suction plate, the front surface of the loading plate 152 of the second substrate mounting unit 150 adsorbs and fixes the substrate (G) to fix the substrate (G). Transfer. In such a configuration, it is possible to prevent a malfunction such as dropping the substrate G and to transfer (transfer) the substrate G more stably.

The linear motor 154 and the rotating motor 133 in a state in which a vacuum is applied through the vacuum suction hole H to suck and fix the substrate G to the loading plate 152 of the second substrate mounting unit 150. By rotating or rotating the rotary table 131 by the operation of), the substrate (G) is transferred to the second attachment process position.
