{Cutting Apparatus for Film Sheet}

The present invention relates to a film sheet cutting apparatus. More specifically, the roll film is placed on a cutting stage so that the roll film can be cut, and in this state, the roll film is brought into close contact with the cutting stage so that the roll film can be brought into close contact with the cutting stage. The film transfer module and the roll film do not interfere with each other during the operation of the film transfer module, thereby preventing the roll film from being damaged, reducing the product defect rate, and mounting on the cutting stage The present invention relates to a film sheet cutting apparatus which can be conveniently applied even in the case of cutting a film sheet of various sizes by mounting the contact contact means in such a manner that positional adjustment is possible along the conveying direction of the roll film.

The touch screen panel is an input device that allows a user to input a command by selecting an instruction displayed on a screen of a video display device as a human hand or an object. Recently, terminals and terminals of various communication devices have been reduced in weight and thickness Such a touch screen panel is widely used so that the display area can be broadened.

The touch screen panel is provided on the front side of the image display device and converts a contact position directly touching a human hand or an object into an electrical signal, so that the instruction content selected at the contact position is received as an input signal. Such a touch screen panel can be replaced with a separate input device connected to a video display device such as a keyboard and a mouse.

Such a touch screen panel is formed by stacking a plurality of film sheets formed in a film form. In general, the touch screen panel includes a sensor film provided with a touch input signal, an FPCB substrate And a window disposed on an upper portion of the sensor film and the FPCB substrate are coupled to an upper portion of another display panel in a state of being stacked up and down.

In the sensor film, a sensing pattern is formed so as to recognize a user's touch input signal. In order to secure transparency and visibility of light generated from the display panel, indium tin oxide (ITO) As shown in FIG. Such a sensor film is formed by stacking the upper ITO film and the lower ITO film vertically.

The window is laminated on the sensor film in the form of wrapping the sensor film to protect the sensor film. A transparent adhesive such as OCA (Optically Clear Adhesive) film is inserted between the window and the sensor film.

According to such a structure, in the process of manufacturing a touch screen panel, a lamination process for bonding a plurality of film sheets formed in a thin film form such as an upper ITO film, a lower ITO film, an OCA film, and a window is required. In this case, each of the films is generally manufactured in the form of a roll, and the roll-shaped film is cut into a predetermined length to form a film sheet, and then the lamination process is performed in such a manner that the film sheets are bonded to each other.

Accordingly, in the process of manufacturing a touch screen panel, a film sheet cutting apparatus for cutting a roll-shaped film into a film sheet of a predetermined length is required. The conventional film sheet cutting apparatus according to the related art cuts a roll- There is a problem that the film sheet is damaged in the process of transferring the formed film sheet.

For example, since the roll-shaped film is wound around the rollers for a considerable period of time, when the roll-film is unwound, a restoring force to return to the roll shape is generated. That is, the roll-shaped film is curled in a curved shape in one direction in a state in which the film is unwound. At this time, in the conventional film sheet cutting apparatus according to the related art, it is very difficult to maintain the accuracy of the operation due to the curl deformation of the roll film in cutting and conveying the roll film in which the curl deformation has occurred. Further, if the cutting and conveying process is performed on the roll film in a state where the roll film is curled, the moving parts of the film sheet cutting apparatus interfere with the roll film during the operation to damage the film, And the like.

A separate guide roller 110 may be disposed in front of the cutting stage 200 to guide the feeding path of the roll film RF.

The cutting stage 200 is formed such that a roll film RF unwound from the loading roller 100 is supplied and mounted, and may be formed in various shapes such as a rectangular flat plate shape. A separate contact contact means 500 is mounted on the cutting stage 200 so that the roll film RF can be brought into close contact with the upper surface of the cutting stage 200, which will be described later in detail.

The cutting module 300 is configured to cut the roll film RF seated on the cutting stage 200 by a predetermined length to form the film sheet FS. 1, the cutting module 300 includes a cutting blade 310 for vertically moving up and down the cutting stage 200 to cut the roll film RF and a cutting blade 310 for moving the cutting blade 310 in a vertical direction And a cutting drive unit 320 for driving the substrate.

In this state, the roll film RF is cut by the cutting module 300, And the film sheet FS is transported and transported to the sheet-metal part 600 by the film transport module 400. The film sheet FS is transported to the sheet-

As described in the background art, since the roll film RF is seated on the cutting stage 200 in the curled state, when the external force is not applied as shown in FIGS. 2 and 3, The end portion has an upward curved shape along the transporting direction.

If the roll film RF is maintained in the curled state, the film transfer module 400 may interfere with the roll film RF during the movement of the film transfer module 400, thereby causing damage to the roll film RF. have. Therefore, according to the embodiment of the present invention, the cutting stage 200 is provided with the contact contact means 500 for bringing the roll film RF unwound from the loading roller 100 into close contact with the upper surface of the cutting stage 200 do.

The close contact means 500 is configured to bring the end portion into close contact with the cutting stage 200 along the conveying direction of the roll film RF. That is, since the roll film RF is cut at the cutting module 300 and one end thereof is cut into a free end state as shown in FIG. 2, an external force is not applied, . Therefore, the close contact means 500 is configured to bring the end portion of the roll film RF into close contact with the cutting stage 200.

Such contact contact means 500 can be formed in various ways. For example, it may be configured to include an air pressure nozzle (not shown) disposed at an upper portion of the cutting stage 200 and spraying air pressure to the end portion of the roll film RF though not shown. However, in this case, fine dust may be generated due to pneumatic injection, and the adhesion performance may be weak. Therefore, the contact contact unit 500 according to one embodiment of the present invention includes a vacuum adsorption port 510, 520). ≪ / RTI >

The vacuum adsorption port 510 is configured to be attached to the end of the cutting stage 200 along the conveying direction of the roll film RF to vacuum adsorb the roll film RF toward the cutting stage 200 side, 520 are connected to such a vacuum adsorption port 510 and configured to supply or release vacuum pressure. At this time, as shown in FIG. 3, the vacuum adsorption ports 510 may be mounted on both sides in the width direction of the cutting stage 200, respectively, and a plurality of vacuum adsorption ports 510 may be mounted on both sides.

When the roll film RF is placed on the cutting stage 200, the air pump 520 is operated to vacuum-suck the end portion of the roll film RF through the vacuum adsorption port 510, As shown in Fig. In this state, the roll film RF is not formed in an upward curved shape due to the curled deformation, but is in intimate contact with the cutting stage 200. Therefore, in the operation of the film transport module 400, Interference of the film (RF) does not occur, damage of the roll film (RF) is prevented, and workability is improved.

[

In this state, as shown in Fig. 8, the transport block 410 is moved backward to traverse the roll film RF to the upper surface of the cutting stage 200. 9, the vacuum pressure is released to the vacuum adsorption pad 420 to seat the roll film RF on the cutting stage 200, and the transport block 410 moves upward and forward again. When the roll film RF is thus placed on the cutting stage 200, the end portion of the roll film RF is formed in an upward curved state by a curl deformation as shown by a dotted line in Fig. At this time, a vacuum pressure is applied to the vacuum adsorption port 510 mounted on the cutting stage 200 to bring the end portion of the roll film RF into close contact with the cutting stage 200 side.

Thereafter, as shown in FIG. 4, the cutting module 300 is operated to cut the roll film RF, thereby forming a new film sheet FS. The film sheet FS is continuously cut from the roll film RF through the repeated cyclic operation flow.
