The present invention relates to a laser device for cutting a polarizing film, and more particularly, a horizontal reflector (M1) and a horizontal reflector (M1) for reflecting a laser beam while moving the laser device for cutting the polarizing film in a longitudinal direction. The laser beam reflected from the laser beam is reflected in the laser head in the same and lateral directions as the horizontal reflector M1, and is composed of a vertical reflector M2 that projects the laser beam onto the polarizing film. The present invention relates to a laser device for cutting a polarizing film.

In general, as much attention has been paid to the increase in size and quality of display devices as a medium for transmitting image information, it is noted that various flat panel display devices have been developed and disseminated in place of CRT (Cathode Ray Tube), which has been used until now. same. One of the flat panel display devices, the liquid crystal display device has developed far beyond the CRT in terms of image quality and color, and has become a main product dominating the world market.

The general manufacturing process of the general TFT-LCD panel (Thin Film Transistor Liquid Crystal Display Panel) constituting the liquid crystal display device as described above is as follows. First, as an overview, one pixel (comprising three subpixels R, G, and B) of a TFT-LCD panel is as fine as about 0.3 mm in width. Of course, the TFT (Thin Film Transistor) that fits in it is smaller. Furthermore, to reach a resolution of 1600 x 1200, the number of pixels is 1.19 million, which requires 3 times (R, G, B), considering each sub-pixel, and requires 576 million TFTs. Therefore, a semiconductor level process is required as a process that requires high precision of the entire process itself.

Meanwhile, the manufacturing process of the TFT-LCD panel as described above is largely divided into a TFT process, a color filter (CF) process, a cell process, and a module process, and has two glasses that have undergone a TFT process and a CF process. One panel is made through a cell process, and a panel processed through a cell process is made through a module process, and a TFT-LCD panel that is actually used for a monitor or a TV is made.

First, the TFT (Thin Film Transistor) process is a process of forming a basic electrode, which makes the electrode of each cell the most basic and essential process. The process sequence includes five steps of gate electrode generation, insulating film and semiconductor film generation, data electrode generation, protective film generation, and pixel electrode generation, but at least one pattern process is required for each step. This pattern process can be called the core of the TFT-LCD panel manufacturing process. Similar pattern processes are required for the CF process as well as the TFT process.

The pattern process as described above is a very precise and complicated process by itself. At least this process is performed several times to make a single TFT-LCD panel. Of course, the same process is not used then, but the schematic process is similar. This pattern process consists of deposition, cleaning, photoresist (PR) coating, exposure, development, etching (PR) process, PR stripping (Strip process), and inspection process. This is necessary.

TFT-LCD, on the other hand, does not emit light on its own like PDP or OLED (organic EL), but controls the brightness of light by controlling the arrangement of liquid crystals in each cell for constant light from the backlight. Since the backlight itself is white light, CF (Color Filter) plays an important role in changing the arrangement of liquid crystals to control the amount of light, but to make R, G, and B to realize color. This CF is located on the top of the TFT-LCD panel and is made through a process separate from the TFT process. The CF process also requires the pattern process described above.

The above-described CF (Color Filter) process requires a BM (Black Matrix) process (deposition, cleaning, PR coating, exposure, development, etching, and peeling pattern process), and pixel-by-pixel process (this pattern process was performed as described above. It is a slightly different process from the process of evaporation and cleaning without the need for the deposition and cleaning process, by applying a color-sensitive photosensitive material to the process of exposure and development) and the ITO process (Indium Tin Oxide: good permeability and conductivity, chemical and thermal stability Excellent transparent electrode material). In addition, some additional processes may be added depending on the type of panel (VA, IPS, TN, etc.).

In addition, the Cell process is a process of combining and cutting two glasses made in the CF process and the TFT process into one, and cleaning the CF and TFT, polyamide printing, rubbing process, spacer scattering, and bonding. (TFT substrate and CF substrate are precisely bonded), cutting (the bonded substrate is cut and separated into respective panels), liquid crystal injection, and final inspection.

The module process of the above-described TFT-LCD panel manufacturing process is a final step for attaching a polarizing film (or a polarizing plate), a PCB, a backlight unit, etc. to a panel made of a cell process as a final process for making a finished product panel. , Polarizer film attachment, TAB attachment, autoclave, PCB attachment, BLU (Back Light Unit) assembly, and inspection.

In the above-described module process, the polarizing film attached to the upper and lower parts of the panel has a function of making the incident light while vibrating in various directions to be light that vibrates only in one direction (that is, polarization). The polarizing film is usually attached to cross 90 degrees. In this case, a protective film for protecting the polarizing film is attached to each of the upper and lower surfaces of the polarizing film. In order to attach the polarizing film to the upper and lower surfaces of the panel, the protective film on the upper and lower surfaces of the polarizing film is first applied. After removal, it should be attached to the top and bottom of the panel.

On the other hand, the polarizing film (Polaroid Film) refers to a film having a property that can pass or block the vertical or horizontal polarization of the incident light, thin film transistor liquid crystal display device (TFT-LCD) such as notebook computers and monitors And optical films used for camera special effects filters and stereoscopic glasses. Although the intensity of light emitted from the backlight of the LCD module is equal in all directions, the polarizing film transmits only the light oscillating in the same direction as the polarization axis, and absorbs or reflects the other light to create polarization in a specific direction. Do it. When the polarization passes the LCD liquid crystal, the brightness of the pixel is changed by electrically adjusting the alignment direction of the liquid crystal for each pixel.

In order to attach the polarizing film to the upper and lower surfaces of the panel, the polarizing film is subjected to a process of cutting the polarizing film into a polarizing plate having a predetermined size so as to correspond to the size of the panel. The mechanical cutter is used to cut the polarizing film to correspond to the size of the panel.

Therefore, in the case of the polarizing film cutting device according to the prior art as described above, since a large amount of dust is generated in the process of cutting the polarizing film through the shooter cutter, a separate treatment process for treating the generated dust is required. do. Since a separate dust treatment process is required as described above, the production cost increases considerably and the yield decreases due to the occurrence of environmental treatment costs.

In addition, in the case of the polarizing film cutting device according to the prior art as described above, if the polarizing film is cut through the shooter cutter, the cutting surface of the polarizing film is not uniform, requiring a polishing process to uniformly polish the cutting surface of the polarizing film. As a result, the additional process causes problems such as an increase in production cost and a decrease in production volume.

In order to solve the problems described above, a cutting device using a laser has been developed and commercialized. Looking at the configuration of the cutting device using a laser, the entire laser housing in the fixed state of the polarizing film is fixed in the longitudinal direction of the polarizing film. Since it is made of a simple cutting structure that is moved in the transverse direction to cut the polarizing film there is a problem that the cutting precision caused by moving the entire laser housing is reduced.

Hereinafter, a laser device for cutting a polarizing film of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a polarizing film (POL) cutting system 100 using a laser to which a laser device for cutting polarizing film 150 according to the present invention is applied will be described. Winding device 110, the polarizing film 10 supplied through the winder device 110 to rotate the plurality of rollers to support the rotatable rotatable continuous to be made through a plurality of rollers The polarizing film transfer which transfers the flattened polarizing film 10 which spreads the flat curled polarizing film 10 to the flat plate shape, and the flattened polarizing film 10 through the dancing roller device 120 to the rear horizontal surface of a transfer line. The device 130, the polarizing film adsorption device 140, the polarizing film adsorption device 140 for fixing the polarizing film 10 transported through the polarizing film transfer device 130 through the vacuum adsorption fixed by vacuum adsorption Polarizing film (10) Laser device 150 for cutting through the projection of the laser to form a polarizing plate 20, the polarizing plate discharge device 160 for discharging the polarizing plate 20 formed in a predetermined size through the laser device 150 on the rear-side horizontal plane And a polarizing plate aligning device 170 configured to stack and arrange the polarizing plates 20 transferred to the rear side on the transfer line through the polarizing plate discharge device 160.

Looking at the transfer process of the polarizing film 10 through the polarizing film cutting system 100 using the laser applied to the present invention configured as described above, first, rotating the polarizing film 10 in the roll state to the winder device 110 When coupled to the polarizing film feeder 130 via the dancing roller device 120 in the coupled state, and then transferred through the drive of the polarizing film feeder 130, the polarization of the roll state coupled to the winder device 110 The film 10 is unrolled while the polarizing film 10 in the curled state is flattened while passing through the dancing roller device 120.

On the other hand, as described above, the polarizing film 10 is flattened through the dancing roller device 120 to a control controller (not shown) that controls the entire cutting system 100 through the polarizing film transfer device 130. After being transferred to the set size and guided to the polarizing film adsorption device 140, the transport of the polarizing film 10 is stopped, and the polarizing film adsorption device 140 vacuums the polarizing film 10 positioned thereon. Fixed by adsorption. That is, while the polarizing film 10 is fixed by the polarizing film adsorption device 140, the transfer of the polarizing film 10 is stopped.

As described above, when the polarizing film 10 is fixed to the upper portion of the polarizing film adsorption device 140 by vacuum adsorption, the laser device 150 is driven to cut the polarizing film 10 to a predetermined size. That is, the laser device 150 cuts the polarizing film 10 to a predetermined size and forms the polarizing plate 20. After forming the polarizing plate 20 by cutting the polarizing film 10, the vacuum adsorption of the polarizing film 10 and the polarizing plate 20 is released and at the same time, air is discharged from the polarizing film adsorption device 140. In order to float the polarizing film 10 and the polarizing plate 20, the polarizing film 10 and the polarizing plate 20 may be smoothly transferred.

Next, as described above, the polarizing film 10 and the polarizing plate 20 are floated by air discharged from the polarizing film adsorption device 140, and the polarizing film transporting device 130 and the polarizing plate are in a floating state. When the discharge device 160 is driven, the polarizing film 20 is discharged by the polarizing plate discharge device 160 and the polarizing film 10 is transferred to the polarizing film adsorption device 140 by the polarizing film transfer device 130. Are transferred. In this case, the polarizing film transporting device 130 and the polarizing plate discharging device 160 for transporting the polarizing film 10 and the polarizing plate 20 are driven at the same speed and are transported in the same direction. Do not cause interference.

As described above, when the polarizing film 10 and the polarizing plate 20 are transferred by the driving of the polarizing film conveying device 130 and the polarizing plate discharging device 160, the polarizing plate 20 is formed by the polarizing plate discharging device 160. The transfer is aligned with the polarizing plate aligning device 170, the polarizing film 10 is transferred by the polarizing film transfer device 130 at the same speed as the polarizing plate 20 is transferred to the polarizing film adsorption device (140). Therefore, the cutting of the polarizing film 10 by the laser device 150 can be seen that the transfer of the polarizing film 10 and the polarizing plate 20 is made at the same time.

Next, in order to cut the polarizing plate 20 of one junk machine, the polarizing film 10 adsorbed and fixed through vacuum in the polarizing film adsorption device 140 of the polarizing film cutting system 100 using the laser described above is used. The laser device 150 of the present invention will be described in detail. Figure 4 is a perspective configuration diagram schematically showing a laser device for cutting a polarizing film according to the invention, Figure 5 is a front configuration diagram schematically showing a laser device for cutting a polarizing film according to the invention, Figure 6 is a polarizing film cutting according to the invention It is a schematic side view of a laser device.

4 to 6, the polarizing film cutting laser device 150 according to the present invention is installed to be movable in the longitudinal direction corresponding to the conveying direction of the polarizing film 10 inside the laser housing 152. The horizontal reflector M1 reflects the oscillated laser beam in the lateral direction of the polarizing film 10, and is installed at a predetermined distance from the horizontal reflector M1 inside the laser housing 152, but is polarized film 10. The vertical reflector M2 and the laser housing 152 which are installed to be movable in the longitudinal direction and the transverse direction of the laser beam to reflect the laser beam reflected from the horizontal reflector M1 through the projection in the vertical direction. It is configured to include a reflector moving means installed in the inside to move the longitudinal reflector (M2) in the longitudinal direction and the vertical reflector (M2) in the longitudinal and transverse directions.

In the configuration of the laser device 150 according to the present invention configured as described above, the horizontal reflector M1 is inside the laser housing 152 to reflect the oscillated laser beam to the vertical reflector M2 in the transverse direction. Installation is fixed. At this time, the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 are installed on the same horizontal line of the reflecting mirror moving means provided in the laser housing 152 and moved in the same way during the longitudinal movement. That is, the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 constituting the laser device 150 according to the present invention are disposed on the same horizontal line of the reflecting mirror moving means in a form of facing each other, so that the horizontal reflecting mirror M1 is separated from the horizontal reflecting mirror M1. The reflected laser beam is reflected downward in the vertical direction through the vertical reflector M2 so that the polarizing film 10 may be cut.

On the other hand, as described above, the horizontal reflector M1 provided on the same horizontal line of the reflector moving means is installed at an inclination angle capable of converting the oscillated laser beam in the horizontal direction of the vertical reflector M2, and the vertical reflector ( M2) is installed at an inclined angle to reflect the laser beam converted and reflected from the horizontal reflecting mirror M1 downward in a vertical direction so that projection can be made to the polarizing film 10. Therefore, as described above, it can be seen that the horizontal reflector M1 and the vertical reflector M2 are positioned on the same horizontal line to reflect the laser beam in the horizontal direction so that the projection can be performed downward in the vertical direction.

In other words, in the configuration of the laser device for cutting a polarizing film 150 according to the present invention, the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 are simultaneously in the longitudinal direction in the longitudinal direction of the polarizing film 10. In order to reflect the laser beam reflected from the horizontal reflector M1 downward through the vertical reflector M2 in a vertical downward direction, so that the projection can be made on the polarizing film 10. It can be seen that the vertical reflector M2 is positioned on the same line in the transverse direction at all times.

In the configuration of the laser device 150 according to the present invention configured as described above, the vertical reflector M2 is installed to be movable in the transverse direction in addition to the configuration installed in the longitudinal direction as described above, the polarizing film Both longitudinal and transverse cuts of (10) are possible. Therefore, the laser device 150 according to the present invention can cut the polarizing film 10 to a desired size. In addition, it is possible to enable both the longitudinal cutting and the transverse cutting of the polarizing film 10 through the vertical reflecting mirror M2 through the reflecting mirror moving means to be described later.

When cutting the polarizing film 10 through the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 having the structure as described above, the horizontal reflecting mirror M1 when cutting in the longitudinal direction, which is the longitudinal direction of the polarizing film 10. ) And the vertical reflecting mirror M2 are simultaneously moved in the front and rear same direction in the longitudinal direction to cut the polarizing film 10 in the longitudinal direction in the longitudinal direction, and in the transverse direction in the horizontal direction of the polarizing film 10. The vertical reflecting mirror M2 is horizontally moved in the direction of the horizontal reflecting mirror M2 positioned on the same horizontal line to cut the polarizing film 10 in the horizontal direction in the horizontal direction. At this time, the horizontal reflector M1 is stopped.

As described above, the polarizing film cutting laser device 150 according to the present invention allows the polarizing film 10 to be cut in the longitudinal direction and the transverse direction so that the polarizing plate 20 can be cut to a desired size. . At this time, the laser beam reflected downward by the vertical reflector M2 is installed under the laser housing 152 and is projected through the laser head 156 positioned on the same vertical line as the vertical reflector M2. .

On the other hand, the laser head 156 that projects the laser beam reflected downward through the vertical reflector M2 as described above to the polarizing film 10 is a vertical reflector M2 when the vertical reflector M2 moves in the lateral direction. The laser beam moved in the same manner as) and reflected vertically downward through the vertical reflecting mirror M2 can be projected onto the polarizing film 10 through the laser head 156 at all times. In this case, as the means for moving the laser head 156 together with the vertical reflector M2, the LM guide (not shown) and the linear motor (not shown) are similar to the reflector moving means for moving the vertical reflector M2. Can be moved through).

As described above, the laser device 150 according to the present invention moves the horizontal beam in the longitudinal direction of the polarizing film 10 while moving the horizontal reflector M1 and the vertical reflector M2 in the same longitudinal direction. While cutting in the longitudinal direction by projecting, while cutting the polarizing film 10 in the horizontal direction by cutting the transverse direction by projecting the laser beam through the horizontal movement of the vertical reflector (M2) to cut the polarizing film 10 to the desired size It is very easy to cut | disconnect to the polarizing plate 20 of this. That is, the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 are moved in the longitudinal direction in the same direction through the reflecting mirror moving means, or the vertical reflecting mirror M2 of the horizontal reflecting mirror M1 located on the same horizontal line. Since the polarizing film 10 is cut in the longitudinal direction (the longitudinal direction) and the transverse direction (the transverse direction) by moving in the direction or the other direction, the polarizing film 10 can be cut to a desired size.

On the other hand, the reflector moving means constituting the laser device 150 according to the present invention is installed on both sides of the laser housing 152 with the same length, LM rail 1 (154a) is installed in the longitudinal direction parallel to the transfer line, Both ends of the LM block 1 (154b) and the LM block 1 (154b), which are movably coupled to the same position on each side of the LM rail 1 (154a), are supported at both ends and installed in the transverse direction. LM rail 2 154c to which M1 is mounted and fixed, LM block 2 154d movably coupled to LM rail 2 154c to support the vertical reflector M2, and inside the laser housing 152. Installed inside the linear motor 1 (154e) and the laser housing 152 to move the LM rail 2 (154c) in the longitudinal direction to the longitudinal movement of the horizontal reflector (M1) and the vertical reflector (M2). Installed to move the LM block 2 (154d) on the LM rail 2 (154c) It made of the configuration of the linear motor 2 (154f) so that the lateral movement of the reflecting mirror (M2) can be made.

The reflector moving means configured as described above has the LM rail 2 154c by the movement of the LM block 1 154b according to the driving of the linear motor 1 154e when the polarizing film 10 is cut in the longitudinal direction in the longitudinal direction. Is moved in the longitudinal direction to move the horizontal reflector M1 and the vertical reflector M2 in the longitudinal direction. At this time, as described above, the horizontal reflector M1 is fixedly installed on one side of the LM rail 2 154c, while the vertical reflector M2 is movable horizontally through the LM block 2 154d on the other side. Since the LM rail 2 (154c) is longitudinally moved, the longitudinal movement of the horizontal reflector M1 and the vertical reflector M2 is performed. Of course, the longitudinal direction of the polarizing film 10 is made while the longitudinal reflection of the horizontal reflector M1 and the vertical reflector M2 is made while the laser beam is being projected.

In addition, the lateral movement of the vertical reflector M2 through the reflector moving means according to the present invention is the LM block 2 (154d) LM block 2 (154d) in accordance with the drive of the motor 2 (154f) in the state that the LM rail 2 (154c) is stopped. The laser beam is projected onto the polarizing film 10 while moving in the horizontal direction along the rail 2 154c so that the cutting in the transverse direction can be performed. At this time, since the LM rail 2 154c is stopped when the polarizing film 10 is cut in the horizontal direction, the horizontal reflector M1 is naturally stopped, and only the vertical reflector M2 is the LM block 2 154d. It is moved to the left and right of the transverse direction in accordance with the transverse direction of the polarizing film 10 is cut in the transverse direction.

As described above, the longitudinal direction of the polarizing film 10 is cut in the longitudinal direction of the LM rail 2 154c by driving the linear motor 1 154e constituting the reflector moving means. By the movement, the horizontal reflecting mirror M1 and the vertical reflecting mirror M2 are simultaneously moved in the same direction on the same horizontal line, and in the horizontal cutting of the polarizing film 10, the horizontal reflecting mirror M1 and the vertical direction on the same horizontal line According to the driving of the linear motor 2 154f of the reflector M2, only the LM block 2 154d in which the vertical reflector M2 is installed is moved, and is polarized by a laser beam projected downward through the vertical reflector M2. The transverse cutting of 10 is made.

The laser device 10 according to the present invention as described above is the longitudinal direction of the mirror reflector (M1) and the vertical reflector (M2) in the fixed state of the laser housing 152 and the polarizing film 10 on the transfer line is fixed The polarizing film 10 may be cut by the lateral movement and the lateral movement of the vertical reflector M2.
