Description

Optical film peeling device {OPTICAL FILM PEELING DEVICE}

The present invention relates to an optical film peeling apparatus, and in particular, to an optical film peeling apparatus for removing an optical film such as a polarizing film attached to a flat panel display apparatus such as a liquid crystal display.

Flat Panel Display Devices (FPDs) such as Liquid Crystal Display Devices (LCDs) and Organic Light Emitting Display Devices (OLEDs) have the advantage of being light, thin, and small. It is widely used in electronic information devices and the like by replacing a display device.

In general, a liquid crystal display device is a display device capable of displaying a desired image by individually supplying image signals to pixels arranged in a matrix form and adjusting light transmittances of the pixels. To this end, the liquid crystal display has a structure in which a lower substrate on which thin film transistors are arranged and an upper substrate on which a color filter is formed are bonded to each other with a liquid crystal layer therebetween. In addition, polarizing films are formed on the surfaces of the lower substrate and the upper substrate, respectively, to control blocking or transmission according to the transmission direction.

The polarizing film is manufactured with the protective film attached, and after the protective film is removed through an adsorber and a peeling device, the polarizing film is attached to the front and rear surfaces of the liquid crystal panel, respectively.

In such a liquid crystal display device, when a defect occurs due to misalignment or foreign matter inflow after attachment, the polarizing film is removed from the liquid crystal panel through a peeling process to reduce cost, and then regenerated by replacing and attaching a new film.

1A is a perspective view showing a conventional optical film peeling apparatus, and FIG. 1B is a cross-sectional view showing the peeling apparatus of FIG. 1B.

1A and 1B, a conventional optical film peeling apparatus mounts a liquid crystal panel 10 to which two polarizing films 11 and 15 are attached on an adsorption stage 11, but a polarizing film to be peeled ( 15) face the upper side, connect a part of one corner of the polarizing film 15 to the clamp 21 using a connecting tape 4, and connect the clamp 21 and the corresponding corner Are arranged to correspond.

Thereafter, the clamp 21 is moved in a direction inclined by about 45° from one surface of the polarizing film 15 and pulled from the liquid crystal panel 10 to perform a peeling process.

However, according to the recent trend of slimmer LCD devices, there is an increasing demand for thinning optical films such as polarization and polarizing films (Film Patterned Retarder, FPR) for realizing 3D images. Although two PVA films are provided on the front and back sides, as only one PVA film is provided due to thinning, a phenomenon in which the polarizing film is broken during the peeling process often occurred.

The types in which the polarizing film is broken during the above-described peeling process are summarized as follows.

2 and 3 are diagrams showing a cause of breakage of a polarizing film occurring in a conventional optical film peeling apparatus.

Referring to FIG. 2, as the clamp 21 advances in the horizontal direction as the first fracture type of the polarizing film, the polarizing film 15 is separated from the liquid crystal panel 10. This peeling process is largely dependent on the progression degree. It can be divided into an initial stage (a), a mid-term stage (b), and a final stage (c). Here, in the initial step (a), the moving axis of the clamp 21 and the center of the peeling surface coincide so that the tension acting on the polarizing film 15 is applied evenly in all areas, but in the mid-term step ( b) From then on, the center of the moving shaft and the peeling surface become inconsistent, and the tension is concentrated in one area A1, causing breakage. Even in the final step (c), the tension of the region A2 corresponding to one side of the polarizing film 15 removed is concentrated, so that the risk of fracture continues.

Next, referring to FIG. 3, as the second fracture type of the polarizing film, the polarizing film 15 covers the guide bar 41 guiding the surface thereof in the peeling process, and the liquid crystal panel 10 by the clamp 21 It is separated from the surface of the liquid crystal panel 10 and polarizing film 15, it is advantageous to prevent the rupture phenomenon of the polarizing film 15 only by supplying liquid ultrapure water (DI-Water, W) for lowering the tensile force. Conventionally, the ultrapure water supply operation was performed manually using the dropper 31, but the supply amount is not constant, and fractures frequently occur in the region A3 where the amount of ultrapure water is insufficient on both sides of the substrate 10.

In addition, as the third fracture type of the polarizing film, the clamp 21 performs a peeling process by pulling the polarizing film 15 so as to bend more than 160° relative to the horizontal line. At this time, a guide bar 41 that prevents the liquid crystal panel from being lifted and guides the separated polarizing film 15 is used. As a large frictional force acts between the guide bar 41 and the polarizing film 15, it is broken. There was a problem in which the phenomenon occurred.

The present invention has been conceived to solve the above-described problems, and an object of the present invention is to provide an optical film peeling device that solves the problem of breaking a polarizing film during a polarizing film peeling process of a liquid crystal display device.

In order to achieve the above object, the optical film peeling apparatus according to an embodiment of the present invention proceeds the peeling process by pulling the optical film attached to one side of the substrate starting from one corner, but corresponding to the peeling process progress step. A peeling unit that finely adjusts the direction of the optical film so that the tension is not concentrated, a spray unit that automatically supplies ultrapure water in response to the contact surface, and the angle is adjusted to prevent the tension from being concentrated, and the rotation to reduce friction It consists of a guide unit including a guide bar having a roller.

The optical film peeling apparatus according to the embodiment of the present invention can minimize the phenomenon of the polarization film being broken in the polarizing film peeling process of the liquid crystal display device by improving the structure of components such as a clamp, a spray unit, and a support bar provided. There is an effect.

4A and 4B, the optical film peeling apparatus 100 according to the embodiment of the present invention pulls one edge of the stage 110 on which the substrate 10 is mounted and the polarizing film 15 to prevent peeling. A peeling unit 200 in progress, a spray unit 300 for spraying ultrapure water on the contact surface of the substrate 10 and the polarizing film 15, and a peeling area of the polarizing film 15 are guided. It includes a guide unit (guide uint400).

The stage 110 serves to mount the substrate before and after the peeling process, and transfer the substrate 10 to the inside and outside of the optical film peeling apparatus 100. During the peeling process, the polarizing film 15 is subjected to high tension by the peeling unit 200, and the stage 110 prevents the substrate 10 from being dragged along the polarizing film 15 due to the applied force. The current alignment is stably maintained by contacting and fixing the rear surface of the substrate 10 so that it is possible.

The peeling unit 200 is provided with a clamp 210 at the end, and pulls a portion of the polarizing film 15 corresponding to one edge of the substrate 10 through the clamp 210 to attach the polarizing film 15 to the substrate. (10) It plays the role of removing the image. Here, the clamp 210 pulls the polarizing film 15 through a predetermined connection tape (not shown) attached to the edge of the polarizing film 15, and the clamp 210 moves in one direction to polarize The film 15 is peeled off.

At this time, as shown in Figure 2, the tension applied to the polarizing film 15 during the progress of the peeling process is different, respectively, which is the initial stage, the intermediate stage and the final stage (Fig. 2 (a), (b), The size and location of each (c)) will be different. Correspondingly, the peeling unit 200 changes the traveling direction of the clamp 210 for each step to relieve a portion where a large amount of load is applied, thereby suppressing a phenomenon in which the polarizing film 15 is broken.

Referring again to FIGS. 4A and 4B, the spray unit 300 includes a plurality of injectors 310. This spray unit 300 is disposed adjacent to the contact surface of the substrate 10 and the polarizing film 15, and by applying liquid ultrapure water in the form of fine droplets on the contact surface, the substrate 10 and the polarizing film 15 By lowering the adhesive force of the adhesive interposed in the polarizing film 15 is prevented from breaking.

In particular, a plurality of the injectors 310 are arranged side by side along the contact surface by the support 340, and in the embodiment of the present invention, by controlling the turn-on/off of each injector 310 according to the peeling process, Ultrapure water can be evenly applied to all areas of the contact surface, and at the same time, it is possible to minimize the waste of ultrapure water by preventing application to unnecessary areas.

The guide unit 400 serves to guide the upper portion of the polarizing film 15 on the contact surface by being positioned in the direction of separation on the opposite side of the contact surface between the substrate 10 and the polarizing film 15, that is, the polarizing film 15 as the center. Do it. The guide unit 400 includes a guide bar 410 arranged in parallel with the length of the contact surface of the polarizing film 15 in the term “‡, and when peeling, the polarizing film 15 includes the guide bar 410. It is pulled by the clamp 210 in the direction of about 160° from the bottom surface as the center. Accordingly, the peeling unit and the guide unit 400 are set to have the same speed at which they move in the peeling progress direction.

In particular, the guide unit 400 according to the embodiment of the present invention has a structural feature in that the provided guide bar 410 is connected to the support by a rotation shaft, and the angle thereof is finely adjusted according to the progress of the peeling process. Adjusting the angle of the guide bar 410 serves to lower the force as the tension to a specific area (A1, A2 in FIG. 2) is concentrated during the peeling process. In addition, although not shown, a rotating roller (not shown) is further provided to reduce frictional force generated in a region in which the guide bar 410 and the polarizing film 15 are in contact.

In addition, each unit of the above-described peeling optical film peeling apparatus 100 should further include a separate sensor member to determine the current peeling process progress, and at least one of these sensor members is an optical film peeling apparatus. It is placed on one side of (100) to photograph the current location in real time.

According to this structure, the optical film peeling apparatus 100 according to an embodiment of the present invention adjusts the pulling angle of the peeling unit 200 and the guide angle of the guide bar 400 to provide tension concentrated in a specific area during the peeling process. It is characterized in that it is possible to mitigate the lack of application amount of ultrapure water by the selective automatic spraying function of the spray unit 300, and to minimize the fracture phenomenon of the polarizing film 15 through the frictional force reduction structure of the guide unit 400. have.

At this time, although not shown, a spray unit (not shown) is also disposed to face the contact surface.

Thereafter, the clamp 210 and the guide bar 410 are moved in the same direction to remove the polarizing film 15 from the substrate according to the direction of progress. In the initial step (Fig. 2 (a)), the polarizing film 15 The tension acting on the contact surface of is the same in all areas, but the tension is concentrated to one side of the contact surface after the intermediate stage (Fig. 2(b)) (Fig. 2(b), A1).

As an example, as the tension is concentrated in the area A1, when the bearing rail 230 moves the rotation shaft 220 in the right direction of the traveling direction, that is, in the upper direction when viewed in the drawing, the clamp 210 becomes the rotation shaft 220 ), it proceeds in a direction slightly twisted upwards in the direction of progression. Accordingly, the polarizing film 15a in the previous state is subjected to a peeling process as the polarizing film 15 in a state in which the tension concentration in the area A1 is less.

For this drive, as shown in FIGS. 5B and 5C, the clamp 210 of the peeling unit 200 has first and second clamps 211 for pulling the connecting tape 4 disposed between the spaced spaces. 213). Here, the second clamp 213 moves up and down by the rotation of the lifting member 212 connected to the lower part, and through the lifting movement, the second clamp 213 is in close contact with the first clamp 211 to fix the connection tape 4. The clamp 210 is connected to the rotation shaft 220 through a coupling member 215.

The rotation shaft 220 moves in a horizontal direction perpendicular to the separation progress direction on the bearing rail 230, and according to the movement, the angle of the clamp 210 is finely changed so that the separation progress direction does not change abruptly. These rotation shafts 220 may be provided with two vertically in order to stably maintain the position of the clamp 210.

In addition, the bearing rail 230 is provided in a direction perpendicular to the direction in which the separation proceeds, and a plurality of ball bearings (not shown) are provided at a portion coupled with the rotation shaft 220 to easily move the rotation shaft 220 in the left and right directions. Will be ordered.

A plurality of injectors 310 are fixed in a row on the coupling table 340, and the coupling table 340 is arranged side by side with the guide bar 410. That is, as the substrate 10 and the polarizing film 15 are disposed in a direction parallel to the contact surface, a certain amount of ultrapure water is evenly sprayed onto the contact surface. The ultrapure water used here serves to reduce the tensile force by being supplied to the contact surface in the form of a passive dropper.

These injectors 310 are individually operated according to the control signal, and turn-on and turn-off are repeated according to the progress of the peeling. Specifically, during the peeling process, in the initial stage (Fig. 2 (a)), as the peeled portion is small, only the injectors 310 disposed in the center are turned on, and the injectors 310 disposed on the side are turned on. ) Can be turned off. In addition, in the intermediate stage (Fig. 2 (b)), all the injectors 310 can be turned on, and in the final stage (Fig. 2 (c)), gradually turned off from the side injectors 310. I can.
