The present invention relates to an apparatus for attaching a polarizing plate, and more particularly, since it can be manufactured in a simple structure without a supply part and a recovery part used in the prior art, it is easy to maintain and reduce the material cost for the adhesive tape. It is possible to drastically reduce various loss occurrences that can be caused in general, and it is not necessary to perform difficult and complicated synchronous control, especially for the supply part and the recovery part. It is about.

Recently, the flat panel display (FPD) has begun to emerge as the electronic display industry is rapidly developing among the semiconductor industry.

A flat panel display (FPD) is an image display device that is thinner and lighter than a cathode ray tube (CRT), which has been mainly used as a display for a TV or a computer monitor, and includes a liquid crystal display (LCD, liquid). crystal displays), plasma display panels (PDPs), organic light emitting diodes (OLEDs), and the like.

One of such flat display (FPD) thin film transistor (TFT-LCD) liquid crystal displays (TFT-LCDs) injects a liquid crystal, which is an intermediate material between a solid and a liquid, between two thin upper and lower glass substrates. It is a device using a kind of optical switch phenomenon that displays the number or the image by generating the contrast by changing the arrangement of the liquid crystal molecules by the electrode voltage difference of the substrate.

Liquid crystal display (LCD) is replacing the existing cathode ray tube (CRT) at a high speed due to the excellent performance of thin, light weight, low power consumption. Therefore, it is widely used in electronic products such as electronic clocks, electronic calculators, TVs, notebook PCs, speed displays and driving systems of automobiles and aircrafts.

Such liquid crystal display (LCD) is largely released as a product through a TFT process, a cell process, and a module process.

The TFT process is very similar to the semiconductor manufacturing process, in which thin film transistors are arranged on a glass substrate by repeating deposition, photolithography, and etching.

The Cell process forms an alignment layer on the TFT bottom plate manufactured by the TFT process and the top plate which is a color filter so that the liquid crystals can be aligned well. The top and bottom plates are formed by corals and seal printing. It is a process of bonding.

The module process attaches a polarizing plate to the completed LCD panel, mounts an integrated circuit (Drive-IC), assembles it with a PCB (Printed Circuit Board), and then back-lights the unit. Point out a series of steps to assemble the tool.

The polarizing plate used in the module process serves to selectively transmit only light that is strongly attached to both sides of the LCD panel and vibrates in a specific direction among the light transmitted through the liquid crystal.

On the other hand, it is difficult to scratch or foreign matter on the surface of the polarizing plate in the process of transferring the polarizing plate to the LCD panel assembly plant. Therefore, after the polarizer is manufactured, a separate protective film is attached to the polarizer. Of course, when the polarizing plate attaching process proceeds substantially, the protective film is peeled off.

Initially, the worker has peeled off the protective film attached to the polarizing plate by manual labor. However, due to the limitations of manual work, the production efficiency is inevitably lowered. In recent years, a polarizing plate is attached to the LCD panel after the protective film is peeled off with a means of peeling the protective film using an adhesive tape. A polarizer attachment device has been proposed to allow a series of processes to proceed.

To this end, a conventional polarizing plate attachment device includes a supply for supplying a new adhesive tape, a contact portion for contact-pressing the adhesive tape to the surface of the protective film so that the adhesive tape can be adhered to the protective film, and used for peeling the protective film. And a recovery section for recovering the exhausted waste adhesive tape. In addition, the supply unit and the recovery unit are provided with driving means for independently driving each of the supply unit and the recovery unit.

Therefore, when the peeling process of the protective film is started, the supply part and the recovery part are respectively driven to rotate, so that a part of the new adhesive tape released from the supply part is used for peeling the protective film toward the outer surface of the contact part, and the adhesiveness of the waste adhesive that has been exhausted is used. The tape is repeatedly carried out for each of the plurality of polarizers in a series of processes recovered in the recovery unit.

By the way, in the conventional polarizing plate attachment apparatus, as described above, the supply portion for supplying the new adhesive tape and the recovery portion for recovering the waste adhesive tape have to be separately provided. This not only makes the device difficult to maintain overall, but also frequently takes a long time to replace the supply part and the recovery part, and causes various losses such as an increase in the loss of material costs for the adhesive tape. There is this.

In addition, in the conventional polarizing plate attachment apparatus, since the rotational speed between the supply and the recovery unit must be precisely synchronously controlled in order for the supply and recovery of the adhesive tape to proceed smoothly, there is a problem of substantially deriving the difficulty of synchronous control. If the synchronous control between the supply unit and the recovery unit is not properly performed, the adhesive tape may be stretched or broken, and this may cause a malfunction of the related sensor.

An object of the present invention, since it can be manufactured in a simple structure without the supply and recovery portion used in the prior art, not only easy maintenance, but also a variety of losses that can be caused overall, such as reducing the material cost for the adhesive tape It is possible to provide a polarizing plate attaching device which can greatly reduce the occurrence of loss, and in particular, since it is not necessary to perform difficult and complicated synchronous control on the supply part and the recover part.

The object is, according to the present invention, a polarizing plate support die for supporting a polarizing plate attached to a protective film (Protecting Film) on one surface; An apparatus body provided at one side of the polarizing plate support die with the polarizing plate interposed therebetween and movable in a plate direction of the polarizing plate support die; And at least one film peeling unit having a roller adhered to the protective film and detachably coupled to the apparatus main body and peeling the protective film from the polarizing plate in association with movement of the apparatus main body.

As shown in these drawings, a polarizing plate attachment apparatus according to an embodiment of the present invention, a polarizing plate support die 10 for supporting a polarizing plate 1 is attached to a protective film (1a, Protecting Film) on one surface, The device body 20 provided in the upper region of the polarizing plate support die 10 with the polarizing plate 1 interposed therebetween and movable in the plate direction of the polarizing plate support die 10, and a roller adhered to the protective film 1a ( It includes a plurality of film peeling unit (30) detachably coupled to the device body 20 having a 32, and peeling off the protective film (1a) from the polarizing plate 1 in conjunction with the movement of the device body (20).

The polarizing plate support die 10 is a portion that supports the polarizing plate 1. That is, when the polarizing plate 1 of the object to be provided is provided in a separate polarizing plate supply unit (not shown), the polarizing plate 1 is placed on the upper surface of the polarizing plate support die 10.

The polarizing plate 1 placed on the upper surface of the polarizing plate supporting die 10 should not be arbitrarily moved during the peeling operation of the protective film 1a. Therefore, at least the polarizing plate 1 needs to be fixed on the upper surface of the polarizing plate support die 10 until the peeling operation of the protective film 1a is performed. Therefore, the polarizing plate support die 10 may be provided with a separate fixing means for fixing the polarizing plate (1).

The fixing means may be implemented in various ways, but in the present embodiment, the polarizing plate 1 is fixed on the upper surface of the polarizing plate support die 10 by the vacuum adsorption method. Therefore, it is preferable that a plurality of vacuum holes (not shown) are formed on the surface of the polarizing plate support die 10 in connection with a vacuum pump (not shown).

The device body 20 is provided in the upper region of the polarizing plate support die 10. One side of the apparatus main body 20 is detachably coupled to a plurality of film peeling unit 30 to be described later in detail. The rear of the device body 20 is further provided with a support frame 22 which is provided in parallel with the polarizing plate support die 10 along the direction of movement of the device body 20.

In addition, an actuator (not shown) for moving the apparatus main body 20 in the plate surface direction of the polarizing plate support die 10 is coupled to the support frame 22. An actuator capable of controlling the position may be applied to a pneumatic, hydraulic, or pneumatic composite cylinder, a motor, and the apparatus main body 20 may be moved back and forth by the operation of the actuator.

That is, as shown in detail in Figure 5, after the plurality of film peeling unit 30 is adhered to the protective film (1a), and lifts the protective film (1a) slightly upward, the device body 20 by the operation of the actuator By retreating), the peeling operation of the protective film 1a can proceed from the polarizing plate 1 fixed to the polarizing plate support die 10.

On the other hand, the device body 20, in addition to the film peeling unit 30, the sensing unit for detecting the peeling unit unit 50, the film support knife 60, the protective film (1a) for driving the film peeling unit (30). (Not shown) and a plurality of grippers 70 and the like for chucking the protective film 1a peeled from the polarizing plate 1 are further provided, which will be described in parallel in the description of the film peeling unit 30. Shall be.

 The film peeling unit 30 is detachably coupled to one side of the front surface of the apparatus body 20. In the present embodiment, the film peeling unit 30 is coupled to the spaced apart from each other at the front of the device body 20 is combined. However, since the scope of the present invention is not limited thereto, the number of the film peeling units 30 may be appropriately adjusted. For example, when the protective film 1a is to be peeled off from the small polarizing plate 1, fewer than four film peeling units 30 may be provided, and the protective film 1a may be removed from the large polarizing plate 1. In the case of peeling off, it will be preferable to provide more than four film peeling units 30.

As shown in FIGS. 2 and 3, the film peeling unit 30 protrudes from the unit body 31 and one surface of the unit body 31 so as to freely support the roller 32. It includes a pair of roller support (33). The roller 32 may be freely rotated at the corresponding position by being coupled by the hinge pin 35 between the pair of roller support portions 33.

The outer surface of the roller 32 is wound with an adhesive tape 32a coated with an adhesive material having a predetermined viscosity such that the roller 32 can be repeatedly used at least several times or tens of times, but at least two times are wound. Of course, in some cases, the adhesive tape 32a may be wound once, but in the case of winding once, the adhesive tape 32a is likely to be easily separated from the roller 32. Therefore, it may be advantageous to wind the adhesive tape 32a at least twice.

Locking and unlocking of the film peeling unit 30 with respect to the apparatus body 20 in the apparatus body 20 and the film peeling unit 30 so that the film peeling unit 30 can be easily detached from the apparatus body 20. Locking means 40 is provided.

The locking means 40 is provided in the apparatus body 20 so as to be movable toward the protrusion part 41 (see FIG. 2) provided in the unit body 31 of the film peeling unit 30 and the protrusion part 41. 41, a locker 42 (see FIG. 3) that is locked and unlocked. In addition, at the rear end of the unit body 31 of the film peeling unit 30, a pair of engaging portions 37 are further formed on the support bar 26 formed in the apparatus main body 20 upwardly.

2 and 3, a pair of engaging portions 37 formed at the rear end of the unit body 31 of the film peeling unit 30 are supported on the support bar 26 formed on the apparatus body 20. The film peeling unit 30 can be easily coupled to the apparatus main body 20 by lowering the rocker 42 formed in the apparatus main body 20 to be locked downward and locked to the protrusion 41 in a state of being caught upward. That is, the film peeling unit 30 can be easily coupled to the apparatus main body 20 only with a simple one-touch operation. Therefore, compared with the related art, the replacement time of the corresponding parts can be significantly reduced, thereby reducing the time loss.

In order for the roller 32 of the film peeling unit 30 to contact the protective film 1a of the polarizing plate 1, the film peeling unit 30 needs to be raised and lowered with respect to the apparatus body 20. To this end, the apparatus body 20 is further provided with a unit driving unit 50 for driving the film peeling unit 30 so that the roller 32 of the film peeling unit 30 approaches and is spaced apart from the protective film 1a. . The unit driving unit 50 is coupled to the film peeling unit 30, the elevating rail unit 51 for elevating and lowering the film peeling unit 30, and the film peeling unit 30 by the elevating rail unit 51 It is provided with a power generating unit (not shown) for generating a driving force to be raised and lowered.

On the other hand, the film peeling unit 30 is lowered by the unit driving unit 50 so that the roller 32 of the film peeling unit 30 contacts the protective film 1a, and then the apparatus main body 20 is retracted by the actuator. While the protective film 1a is peeled off from the polarizing plate 1, a part of the protective film 1a may be folded. This may be noticeable in the area of the protective film 1a which is located between the rollers 32 spaced apart from each other.

As such, when the protective film 1a is partially folded and peeled from the polarizing plate 1, the protective film 1a may not be smoothly peeled off, and the protective film 1a may be folded in the process of being peeled off. This may cause damage to the polarizing plate (1).

Thus, in the polarizing plate attachment device of the present embodiment, the four rollers 32 adhere the protective film 1a, and the protective film 1a is peeled off while the protective film 1a is peeled off by the movement of the apparatus main body 20. A plurality of film support knives 60 are further provided as a means to be flattened without being folded.

The film support knife 60 is coupled to the apparatus main body 20 and moves together when the apparatus main body 20 moves. The film support knife 60 is made of a flat plate-like body, and is coupled to the apparatus main body 20 so as to be able to tilt at an angle with respect to a horizontal plane. Thus, the protective film 1a, which is peeled off in the process of peeling off the protective film 1a from the polarizing plate 1, can be supported by the film supporting knife 60 so that the protective film 1a is not folded and is flattened. It can be peeled off. Here, the film support knife 60 may be freely tilted at the corresponding position, or may be controlled by a separate tilting driver (not shown).

On the other hand, the polarizing plate attachment device of this embodiment is further provided with a detection unit (not shown) for detecting the presence or absence of peeling of the protective film (1a). As the sensing unit, any one of a vacuum sensor and a photo sensor may be employed.

When the vacuum sensor is applied to the sensing unit, when the protective film 1a is peeled off, the polarizing plate 1 may be detached from the polarizing plate support die 10 to detect whether the protective film 1a is peeled off. When the photo sensor is applied as the sensing unit, the contact of the roller 32 to the protective film 1a may be observed to detect whether the protective film 1a is peeled off. Of course, since the scope of the present invention is not limited thereto, the sensor may be replaced by another sensor or a camera in addition to the vacuum sensor and the photo sensor.

As will be described later in detail, in order to prevent the process from proceeding unnecessarily in a state where the peeling of the protective film 1a fails, the polarizing plate attaching apparatus of the present embodiment selectively controls the progress mode for the peeling process of the protective film 1a. A control unit (not shown) is further provided.

The control unit controls the actuator, the unit driving unit 50, and the like so that when the initial peeling process (primary peeling) fails based on the detection result from the sensing part, the controller returns to the initial state and proceeds the peeling process again. do. Of course, if the primary peeling proceeds normally, the control unit continues to proceed with the secondary peeling.

A plurality of grippers 70 coupled to the apparatus main body 20 and chucking the protective film 1a peeled from the polarizing plate 1 are provided on the front surface of the apparatus main body 20. Each of the plurality of grippers 70 is coupled to a gripper support portion 72 protruding from the apparatus body 20. At this time, the gripper 70 has a structure that can be approached and spaced toward the gripper support unit 72 based on a separate control signal. Therefore, as shown in FIG. 4, the gripper 70 is spaced apart from the gripper support part 72. However, when chucking the peeled protective film 1a as shown in FIG. 5, the gripper 70 is gripper support part ( 72) is approached. Since the gripper 70 can be easily applied to a linear motor or a cylinder, a detailed description thereof will be omitted. On the other hand, since the protective film (1a) is not randomly separated from the gripper 70 chucking the protective film (1a) is provided with a plurality of grippers 70, in the present embodiment, a plurality of film peeling unit (30) The gripper 70 is arrange | positioned between them.

Looking at the process of peeling the protective film (1a) from the polarizing plate 1 by the operation of the polarizing plate attachment device having such a configuration as follows.

First, as shown in FIG. 4, the device body 20 moves horizontally toward one end of the protective film 1a together with the film peeling unit 30 by the operation of the actuator. When the film peeling unit 30 is positioned at one end of the protective film 1a, the movement of the apparatus body 20 is stopped, and the film peeling unit 30 is moved in the Z-axis direction by the unit driving unit 50 at this position. Descend. As the film peeling unit 30 descends, the adhesive tape 32a of the roller 32 provided on the film peeling unit 30 contacts the protective film 1a. At this time, the film support knife 60 is also tilted at a predetermined angle in the Z-axis direction at the rear of the roller 32 to be in contact with the protective film 1a. Therefore, the protective film 1a is flat without being folded.

Next, in order to peel off the protective film 1a, the actuator main body 20 retreats at a low speed by again operating the actuator in the above-described reverse direction (see FIG. 5), and by this operation, the protective film 1a is made of the polarizing plate 1 Peel off). At this time, the roller 32 is free to rotate at the position for smooth peeling of the protective film (1a).

In this operation, if the first peeling process is successfully performed on the protective film 1a, the sensing unit provided in the apparatus main body 20 detects whether the first peeling is normally performed. Here, the primary peeling is not a state in which the protective film 1a is completely peeled off from the polarizing plate 1, and as in FIG. 5, it refers to a state in which the protective film 1a is partially peeled from the polarizing plate 1.

If it is detected that the primary peeling is normally performed by the sensing unit, the secondary peeling is continuously performed by the control mode of the controller to completely peel off the protective film 1a from the polarizing plate 1.

However, if it is determined that the primary peeling is not normally performed, for example, even if the roller 32 is not adhered to the protective film 1a, if only the device body 20 retreats, the operation of the apparatus 20 retreats. The operation is stopped and the original state is returned to the first peeling again. Even though the peeling is not normally performed as described above, it is possible to effectively prevent the peeling process from continuing unnecessarily, thereby reducing various loss occurrences such as eliminating unnecessary work time.

As described above, when the first peeling process is successfully performed on the protective film 1a, and it is determined that the first peeling is successful, the gripper 70 disposed between the film peeling units 30 operates 1 Chucking the protective film 1a of which the peeling was completed. At this time, when the chucking of the gripper 70 to the protective film 1a is completed, the film peeling unit 30 is raised to the Z axis by the unit driving unit 50 so that interference does not occur. Thereafter, a secondary peeling process is performed in which the protective film 1a is completely peeled from the polarizing plate 1 by the movement of the apparatus body 20.

On the other hand, if the protective film (1a) peeling process through this process and the adhesive force of the adhesive tape 32a is exhausted, the film peeling unit 30 is easily separated from the apparatus body 20 in a one-touch manner, and replaced with a new one do.

That is, in a state in which a pair of catching portions 37 formed on the rear end of the unit body 31 of the new film peeling unit 30 prepared in advance is caught upwards by the support bar 26 formed on the apparatus body 20. By lowering the rocker 42 formed on the device body 20 to be locked to the protrusion 41, the film peeling unit 30 can be easily coupled to the device body 20 in a one-touch manner.

Therefore, there is an advantage that can significantly reduce the replacement time of the corresponding parts compared to the conventional. Of course, since the adhesive tape 32a wound on the roller 32 of the film peeling unit 30 in this embodiment is used to have a higher viscosity than the conventional adhesive tape 32a substantially compared to the conventional The replacement cycle of) can be much delayed.

As described above, according to the present embodiment, since it is possible to manufacture a simple structure without a supply part and a recovery part used in the prior art, it is easy to maintain and reduce the material cost for the adhesive tape 32a. Various loss occurrences that can be caused can be greatly reduced, and the control can be simplified since there is no need to perform difficult and complicated synchronous control, especially for the supply part and the recovery part.

In the above-described embodiment, although the protrusion is provided on the unit body of the film peeling unit, the rocker is provided on the apparatus body, on the contrary, the protrusion may be provided on the device body and the rocker is provided on the unit body of the film peeling unit.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.

As described above, according to the present invention, since it can be manufactured in a simple structure without the supply portion and the recovery portion used in the prior art, not only the maintenance is easy but also the material cost for the adhesive tape can be reduced. It is possible to drastically reduce various loss occurrences, and the control can be simplified since there is no need to perform difficult and complicated synchronous control, especially for the supply and recovery.
