Description

System for attaching film to panel

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional film attaching system, and more particularly, to an efficient structure in which a functional film and a panel are supplied from both sides of a film attaching operation line portion, And to a functional film attachment system that can reduce the foot print since the system can be compact and simplified.

Recently, OLED (Organic Light Emitting Diodes) technology is rapidly developing as the electronic display industry is rapidly developing. OLEDs are divided into passive PMOLED and active AMOLED depending on the driving method.

Various functional films such as a polarizer film and an optically clear adhesive film (OCA) are used in the manufacture of such OLEDs.

The polarizing film is attached to the target chain panel to polarize the light, and the optical transparent mounting film plays a role of keeping the screen transparent. After the polarizing film is attached on the panel, the optical transparent mounting film is attached thereon.

On the other hand, in the past, as a technique for attaching a functional film such as a polarizing film or an optical transparent mounting film to a target chain panel, a roll-to-stage method or a drum- Drum to Stage method was common.

In the former roll-to-stage method, a target chain panel is disposed on a set table, and an attach roller is rotated to attach a functional film to a panel. This method is an overhang phenomenon of a film There is a problem that there is a limit in implementation of the degree of attachment due to the error caused by the error.

For reference, in the roll-to-stage type system, the functional film is not properly adsorbed on the stick roller portion, and a sagging phenomenon is likely to occur. As a result, the alignment with the panel is inevitably tripped, This phenomenon is referred to as overhang phenomenon.

On the other hand, the latter drum-to-stage method is a method in which a functional film is adhered to a panel according to a rotation operation of a drum by adsorbing a functional film on the surface of the drum. In the first functional film, There is a problem in that it may cause damage due to contact with the pad and that there is a restriction on various panel size changes due to the limitation of the vacuum area of the drum.

Thus, up to now, the roll-to-stage method and the drum-to-stage method have been mainly used as a method of attaching the functional film to the panel. However, each method has various problems as described above. Method is presented as an alternative, and various companies are currently developing the system.

In this method, a functional film such as a polarizing film is previously adhered to a pressure-sensitive adhesive sheet having a weak viscosity, a functional film is disposed on the panel, and then the pressure-sensitive adhesive sheet is pressed so that the functional film adheres to the panel. After the functional film is attached to the panel, the adhesive sheet is peeled off from the functional film.

On the other hand, in order to attach a functional film to the panel in this manner, that is, to attach a transparent mounting film for optical to a panel to which a polarizing film is attached, there is a demand for a functional film attaching system therefor. That is, a functional film such as a transparent mounting film for optical should be supplied to a film attaching operation line portion to which a functional film is attached, and a panel to which a functional film is attached must also be supplied to the film attaching operation line portion.

In this case, when a functional film and a panel are supplied by simply applying a robot or a carrier, the supply of the functional film and the panel is not efficient, so that the device or system for supplying the functional film and the panel is complicated and difficult to control In addition, considering the fact that the footprint of the system is inevitably large, it is necessary to develop a technique to solve the problem.

The system for attaching the functional film according to the present embodiment is particularly characterized in that the functional film 30 and the panel 10 are provided on both sides of the panel 10 to form a line to which the functional film 30 is attached, The protective film peeling apparatus 200, the functional film cleaning apparatus 600, and the aligning camera apparatus (not shown) on the film attaching operation line unit 300, 400 are disposed.

A film stage 380 for moving the functional film 30 to the functional film attaching apparatus 100 is provided on one side of the film attaching operation line unit 300 and a panel 10 to the functional film adhering apparatus 100 is provided. The functional film 30 and the panel 10 are supplied to the functional film attaching apparatus 100 from both sides of the film attaching operation line portion 300 while being mounted on the film stage 380 and the panel stage 700 respectively. Therefore, the efficiency of supply can be very high, and the simplification of the apparatus can be realized.

In this embodiment, the film stage 380 and the panel stage 700 are each provided in a dual manner, thereby improving the productivity due to a reduction in tact time. However, the film stage 380 and the panel stage 700 may be applied one by one.

The operation of the functional film attaching system of Fig. 2 will be briefly described.

The plurality of functional films 30 to be loaded on the film magazine apparatus 500 are taken out one by one by the interaction of the film magazine apparatus 500 and the film handling robot 310, And is seated on a film stage 380 provided on one side. In this process, the handling robot 310 can check whether the film is fed one by one through the film checker 360. [

The functional film 30 reaches the functional film cleaning apparatus 600 while being moved on the film attaching operation line unit 300 by the action of the film stage 380 and the second protective film 42 ) Is cleaned.

The foreign matter-cleaned functional film 30 reaches the protective film peeling apparatus 200, and the first protective film 41 is peeled off from the protective film peeling apparatus 200. After the functional film 30 reaches the alignment camera apparatus 400, the round edge of the functional film 30 is photographed, and then the functional film 30 is transferred to the functional film attaching apparatus 100, Is adhered to the pressure-sensitive adhesive sheet (110).

On the opposite side of the film magazine apparatus 500, the panel 10 is supplied. After the panel 10 is loaded into the panel loading stage 330, it is turned 180 degrees by the panel turn stage 340. The panel handling robot 320 moves the panel 10 to the panel stage 700 provided on the other side of the film attaching operation line unit 300.

The panel 10 is moved on the film attaching operation line unit 300 by the action of the panel stage 700 and reaches the aligning camera apparatus 400. After the round edge of the panel 10 is photographed, And is moved to the lower portion of the attaching apparatus 100.

Since the functional film 30 is already adhered to the adhesive sheet 110 of the functional film adhering apparatus 100, it is necessary to fix the panel 10 in order to align the relative position of the panel 10 with respect to the functional film 30. [ 10) is advanced. The aligning operation for the panel 10 proceeds while the panel 10 is being moved to the functional film applying apparatus 100.

When the aligning operation is completed, the functional film 30 is attached to the panel 10 through the functional film attaching apparatus 100. [ Thereafter, the second protective film 42 is peeled off by the protective film peeling apparatus 200, and then is taken out of the system through the panel unloading stage 350. The product thus taken out is a product to which the functional film 30 is attached to the panel 10.

Hereinafter, the functional film attaching device 100, the protective film peeling device 200, the functional film cleaning device 600, the alignment camera device 400, the plasma device 800, The panel stage 700 will be described in detail with reference to the drawings.

The film magazine device 500, the film handling robot 310, the film checker 360, the panel loading stage 330, the panel turn stage 340, the panel unloading stage 350, and the other components A detailed description of the configuration of the film stage 380 and the like is omitted, and the description of the operation is replaced with the description of the operation described above.

First, the functional film attaching apparatus 100 is provided on the film attaching operation line unit 300 (see FIG. 2) as shown in FIG. 2 and further shown in FIGS. 3 to 9, And functions to adhere the functional film 30.

The functional film attaching apparatus 100 includes a main body 120 and a functional film 30 attached to the panel 10 using the adhesive sheet 110 (see FIG. 4) And a functional film attaching unit 150 for attaching the functional film.

The attachment device main body 120 forms the external structure of the functional film attachment device 100 according to the present embodiment. In this attaching apparatus main body 120, structures such as the adhesive sheet 110, the sheet mount 130, and the functional film attaching unit 150 are mounted on a position-by-position basis.

The main body driving unit 121 is provided at one side of the main body 120 of the attachment device. The main body driving unit 121 functions to move up and down the main body 120 of the attachment apparatus. Since the attaching apparatus main body 120 is spaced apart from the upper portion of the panel stage 700, the main body driving unit 121 may be provided for adjusting the spacing therebetween.

On the other hand, in the case of this embodiment, the adhesive sheet 110 is used for attaching the functional film 30 to the panel 10. [ In other words, the functional film 30 is attached to the panel 10 using the adhesive sheet 110. Hereinafter, the structure and function of the adhesive sheet 110 will be described first for convenience of explanation.

The adhesive sheet 110 applied to the present embodiment is a medium used for attaching the functional film 30 to the panel 10. That is, in the case of this embodiment, the functional film 30 is first attached to the adhesive sheet 110, as shown in FIGS. 6 to 9, instead of directly adhering the functional film 30 to the panel 10, And the panel 10 are aligned with each other, and then the pressure sensitive adhesive sheet 110 is pressed so that the functional film 30 can be attached to the panel 10.

When the functional film 30 is adhered to the panel 10 via the adhesive sheet 110 as described above, a roll-to-stage method using a conventional set table or a drum- Unlike the Drum to Stage method, it has the advantages of excellent attachment efficiency and quality.

However, when applying the pressure sensitive adhesive sheet 110, when an engineering plastic based pressure sensitive adhesive sheet, an air padding sheet, a porous sheet, or the like is simply applied, ), The lifetime is short, the running cost is high, and the down time is increased due to frequent replacement cycles.

Thus, the present embodiment solves this problem by presenting the following adhesive sheet 110 having an innovative structure. 4 and 5, the adhesive sheet 110 applied to the functional film applying apparatus 100 according to the present embodiment includes an adhesive layer 111, a reinforcing layer 114, and a cushion A layer 112 and an adhesive layer 113. [ The adhesive layer 111, the cushion layer 112, the adhesive layer 113, and the reinforcing layer 114 may be sequentially arranged as shown in FIG.

The adhesive layer 111 is a portion to be adhered to the functional film 30 to be adhered to the panel 10 through an adhesive force based on a van der Waals force.

For reference, van der Waals force refers to the force acting between electrically neutral molecules that do not have a counter-electron. Especially refers to the workforce that works at a relatively long distance. The Van der Waals force is the result of the dispersive forces, and the van der Waals force can explain the force acting between the rare gas atoms, and the factors that form molecular crystals of hydrocarbons such as benzene. The van der Waals force also means an essential force necessary for explaining phenomena such as physical adsorption and the like as well as agglomeration and adhesion of liquid and the present embodiment.

To summarize again, van der Waals force is an extremely weak electrostatic attraction that acts only in close proximity between electrically neutral molecules, and refers to electrical forces acting between covalent molecules.

Particularly, it is possible to perform physical adhesion without the need for extra power through the action of ions. Since the adhesive layer 111 is manufactured based on the van der Waals force, the functional film 30 can be easily adhered, It can be peeled off. That is, since the adhesive layer 111 has a weak viscosity, the adhesive layer 111 can be adhered to the functional film 30, and if the functional film 30 is adhered to the panel 10, The functional film 30 can easily be peeled off, that is, released.

However, if the adhesive layer 111 is applied to the adhesive layer 111 only as a sheet, the desired process may be performed at the initial stage. However, when the adhesive layer 111 is repeatedly used, However, if the adhesive layer 111 is stretched, it will be inevitable that the product corresponding to the high adhesion level becomes unacceptable.

To prevent the occurrence of such a phenomenon, a reinforcing layer 114 is provided on the adhesive sheet 110 applied to the functional film applying apparatus 100 according to the present embodiment. The reinforcing layer 114 is connected to the adhesive layer 111 and serves to reinforce the adhesive layer 111 so that the elongation of the adhesive layer 111 is not increased. In this embodiment, the reinforcing layer 114 is applied as a stainless steel thin plate, and reinforces the adhesive layer 111 while supporting the adhesive layer 111 in a larger area than the adhesive layer 111 as shown in FIG. Since the reinforcing layer 114 is applied as a stainless steel thin plate, it is advantageous to match the elongation.

If the reinforcing layer 114 is further applied and applied as the adhesive sheet 110, the elongation can be reduced to almost zero, and the product can be made to have a high degree of adhesion, and the durability can be improved The lifetime can be prolonged, so that the running cost can be reduced, and the replacement period can be long, so that the down time can be remarkably reduced.

The cushion layer 112 is a layer interposed between the adhesive layer 111 and the adhesive layer 113. The cushion layer 112 serves to provide a buffering force when the functional film 30 is attached to the panel 10. [ Therefore, it is possible to prevent the panel 10 from being damaged while the functional film 30 is attached to the panel 10 while pressing the adhesive sheet 110 with the attaching roller 151, which will be described later.

The adhesive layer 113 serves to bond the cushion layer 112 and the reinforcing layer 114 to each other. Actually, the adhesive layer 111 has a weak viscosity and can adhere well to the cushion layer 112, so that the adhesive layer 113 can be interposed only in the cushion layer 112 and the reinforcing layer 114. [ Of course, if necessary, the adhesive layer 113 may also be provided between the adhesive layer 111 and the cushion layer 112, and such matters are also within the scope of the present invention.

As described above, the adhesive sheet 110 applied to the present embodiment may include an adhesive layer 111, a reinforcing layer 114, a cushion layer 112 disposed therebetween, and an adhesive layer 113, The thickness of the adhesive layer 111 and the thickness of the reinforcing layer 114 may be equal to each other and the thickness of the adhesive layer 111 may be twice or more than the thickness of the reinforcing layer 114. [ For example, if the thickness of the adhesive layer 111 is 300 m, the thickness of the reinforcing layer 114 may be 50 m, and the sum of the thickness of the cushion layer 112 and the thickness of the reinforcing layer 114 may be 50 m . This is because the thick portion is advantageous because the portion where the functional film 30 is substantially adhered is the adhesive layer 111, and the reinforcing layer 114 can be made flexible only when it is thin. However, the scope of the present invention is not limited to these values.

As described above, the adhesive sheet 110 based on the van der Waals force described above is preferably applied to the functional film applying apparatus 100 according to the present embodiment, but this is not necessarily the case. That is, a pressure-sensitive adhesive sheet (not shown) coated with a common conventional adhesive material may be used. Therefore, the scope of the present invention is not limited to these matters.

The first and second sheet clamps 116 and 117 for supporting both ends of the adhesive sheet 110 are attached to both ends of the adhesive sheet 110 so that the adhesive sheet 110 can be mounted at a corresponding position of the attachment apparatus main body 120. [ . The adhesive sheet 110 may be mounted on the sheet receiving portion 130 via the first and second sheet clamps 116 and 117. [

The sheet receiving portion 130 is a structure provided on one side of the attaching device body 120, and is a place where the adhesive sheet 110 is mounted. The first and second sheet clamps 116 and 117 are coupled to both ends of the adhesive sheet 110. The first and second sheet clamps 116 and 117 are mounted on the sheet mount 130, 110 may be installed.

The sheet mounting portion 130 is provided on one side of the attaching device body 120 and includes a first clamp mounting support 131 for supporting the first seat clamp 116 to be mounted thereon, And a second clamp mounting support 132 for supporting the second seat clamp 117 to be mounted thereon.

The functional film attaching apparatus 100 according to the present embodiment is equipped with the functional film attaching section 150 as described above. The functional film attaching portion 150 is provided on the attaching device body 120 so as to be adjacent to the sheet mount portion 130 and is made to adhere to the adhesive sheet 110 with the functional film 30 spread, ) To attach the functional film (30) to the panel (10).

6 to 9, the functional film 30 is attached to the adhesive sheet 110, and then the functional film 30 is attached to the functional film 30 on the basis of the functional film 30. In other words, The functional film 30 can be attached to the panel 10 by pressing the adhesive sheet 110 after aligning the relative positions of the adhesive sheet 10 and the adhesive sheet 110. [ After the functional film 30 is attached to the panel 10, the adhesive sheet 110 is peeled off, i.e., released from the functional film 30. [

The plurality of sheet idler rollers 134 are disposed between the first clamp mounting support 131 and the second clamp mounting support 132 and serve to guide the adhesive sheet 110. In this embodiment, the plurality of sheet idler rollers 134 are rotatably disposed on the side of the first clamp mounting support 131 and the second clamp mounting support 132, respectively, and all of them are used as the non- do.

Although the adhesive sheet 110 is guided by the action of the sheet idler rollers 134, since the adhesive sheet 110 is pressed toward the panel 10 when the functional film 30 is attached, There is a fear that the initial tension of the adhesive sheet 110 is changed. Thus, the seat tension holding portion 140 is provided.

That is, the functional film attaching apparatus 100 is a method of attaching the functional film 30 to the panel 10 using the adhesive sheet 110, so that the adhesive sheet 110 directly fits on the functional film 30, The functional film 30 adhered to the panel 10 may be affected by the degree of stretching or shrinkage of the film 110.

It is necessary to press the functional film 30 on the panel 10 while keeping the tension of the adhesive sheet 110 at a proper level, that is, a level required in the process, in accordance with the stretching amount of the functional film 30, The attachment quality of the film 30 can be improved. To this end, the seat tension holding part 140 is provided.

The sheet tension holding unit 140 is provided on the attachment apparatus main body 120 and serves to maintain the tension of the adhesive sheet 110 when the functional film 30 is attached to the panel 10.

That is, the robot head 240 separates the first protective film 41 from the surface of the panel 10 or the functional film 30 by different six-axis motions of the articulated arm 230, 260). Since the articulated robot 210 has a compact and efficient structure, it is possible to reduce the footprint and control the speed control, the position control, the curved motion control, etc., . Further, it is unnecessary or unnecessary to apply additional additional equipment for secondary peeling or collection of the peeled first protective film 41. For reference, in the case of the present embodiment, the six-axis articulated robot 210 is applied, but if it is more than three axes, it is sufficient.

The adhesive rotating roller 241 for peeling off the film is a roller provided on one side of the robot head 240 and serves to partially peel the first end of the first protective film 41 from the functional film 30 as shown in FIG. . Since the adhesive material is applied to the surface of the adhesive-type rotary roller 241 for peeling off the film, the adhesive-type rotary roller 241 for peeling off the film contacts the end of the first protective film 41, A part of the first protective film 41 may be slightly peeled off and adhered to the adhesive-type rotary roller 241 for peeling off the film as shown in FIG.

The robot head 240 is provided with a film clamp 242 and a clamp actuator 244 for interacting with the sticking rotary roller 241 for peeling off the film.

In this state, The first protective film 41 can be completely peeled off from the functional film 30 by operating the joint robot 210.

The robot head 240 is provided with a first film detection sensor 245 for detecting whether the first protective film 41 is clamped to the film clamp 242. After the first film detection sensor 245 detects that the first protective film 41 is present, the articulated robot 210 is operated as shown in FIG. 17 to completely peel off the first protective film 41 from the functional film 30 . Therefore, even if the first protective film 41 is not clamped between the adhesive rotating roller 241 for peeling off the film and the film clamp 242, it is possible to prevent the operation of the articulated robot 210 from occurring.

In addition to the configurations for peeling and clamping the first protective film 41, the robot head 240 is further provided with a suction unit 246.

The second film detection sensor 263 is provided in the suction and blowing unit 262 and detects whether or not the first protective film 41 from the articulated robot 210 is disposed on the suction and blowing unit 262 . The controller then controls the operation of the film clamp 242 and the adsorption and blowing unit 262 based on the detection signal of the second film detection sensor 263.

When the multi-joint robot 210 inserts the peeled first protective film 41 toward the film storage box 261, the second film detection sensor 263 detects whether or not the first protective film 41 is present And transmits the information to the controller. When the first protective film 41 is present, the first protective film 41 can be adsorbed to the adsorption-purpose blowing unit 262 by the vacuum action of the adsorption-purpose blowing unit 262 by the controller. Then, the articulated robot 210 releases the clamping of the first protective film 41 by the control of the controller and returns to the original position. When the articulated robot 210 is returned to the home position, the first protective film 41 may be collected while being dropped to the bottom of the film storage box 261 by the blowing action of the suction and bleeding unit 262 by the controller .

This is because the second protective film 42 of the functional film 30 adheres to the adhesive sheet 110.

As described above, even if the adhesive sheet 110 is cleanly cleaned, if there is foreign matter on the second protective film 42 of the functional film 30 supplied from the outside, the adhesive sheet 110 is inevitably transferred to the adhesive sheet 110. If the foreign matter adheres to the adhesive sheet 110, the adhesive force of the adhesive sheet 110 is weakened, and the amount of use of the adhesive film for the functional film 30 is reduced. This increases the number of replacement times of the adhesive sheet 110, There is no other way. Therefore, if the foreign matter remaining on the second protective film 42 of the functional film 30 can be removed in advance and the second protective film 42 of the functional film 30 can be cleaned, the adhesive sheet 110 is substantially semi- . To this end, the functional film cleaning apparatus 600 is provided.

The cleaning roller 620 is rotatably provided on the cleaning device body 610 and removes foreign matter remaining on the second protective film 42 of the functional film 30 to perform cleaning.

The cleaning roller 620 has a predetermined cohesive force as a non-motion free rotation type roller. Therefore, when the functional film 30 is moved through the film stage 380, the second protective film 42 of the functional film 30 comes into contact with the cleaning roller 620, so that the foreign matter on the second protective film 42 And may be transferred to the cleaning roller 620.

The transfer roller 630 is a roller that is circumscribed with the cleaning roller 620 and transfers the foreign substance of the cleaning roller 620.

In this embodiment, the transition roller 630 also holds a predetermined adhesion force as the non-motion free rotation type roller. At this time, the adhesion force of the transfer roller 630 is larger than that of the cleaning roller 620, and the size of the transfer roller 630 is larger than that of the cleaning roller 620.

The foreign matter remaining on the second protective film 42 is first transferred to the cleaning roller 620 and then transferred to the secondary transfer roller 630 so that the foreign matter is transferred onto the transfer roller 630 It can remain as it is. Particularly, since the size of the transfer roller 630 is large, many foreign matters can be adsorbed and retained.

The first roller support portion 641 and the second roller support portion 642 are provided on the functional film cleaning device 600 so that the cleaning roller 620 and the transfer roller 630 can be rotated. The first roller support portion 641 is a structure for rotatably supporting the cleaning roller 620 and the second roller support portion 642 is a structure for rotatably supporting the transfer roller 630.

Next, the alignment camera apparatus 400 serves to acquire the alignment image information for the panel 10 and the functional film 30, as shown in FIG. 2 and FIGS. 22 to 25.

As described above, in order to achieve high-precision adhesion performance, it is necessary to acquire the alignment image information for obtaining accurate coordinate values of the panel 10 and the functional film 30, The functional film 30 should be attached. In this case, when a camera for acquiring the alignment image information for the panel 10 and a camera for acquiring the alignment image information for the functional film 30 are separately provided, Which may make it virtually impossible to respond to high-precision products.

Therefore, it is advantageous to apply the alignment camera apparatus 400 to which the single camera 450 is applied as in the present embodiment. Of course, as described later, a plurality of lights 461 and 462 having different light qualities and a single camera 450 are compactly and efficiently applied to the camera device 400 according to the present embodiment, It is possible to cope with high-precision products by acquiring the alignment image information for the film 30.

The alignment camera device 400 capable of providing such an effect has a structure in which a plurality of unit camera modules 420 are coupled to the module frame 410. The unit camera modules 420 are all the same in structure, and each captures an image of the panel 10 and the functional film 30.

The module frame 410 is a structure fixed to one side of the film attaching operation line unit 300 and supports the unit camera modules 420. Since the position of the camera 450 provided in the unit camera module 420 is fixed without being moved after the initial setting of the unit camera modules 420 is performed, the accurate coordinate values of the panel 10 and the functional film 30 .

The unit camera module 420 of one of the plurality of unit camera modules 420 is moved toward or away from the other unit camera module 420 by the module driver 430. The module driving unit 430 may be implemented by a combination of a motor and a ball screw. The pair of unit camera modules 420 are moved toward or away from each other by the module driving unit 430 so that the panel 10 and the functional film 30 can be commonly used.

The unit camera module 420 may include a supporter 440 and a camera 450, a lens 470, a prism 481, and a plurality of lights 461 and 462 mounted on the supporter 440. The structure of all the unit camera modules 420 is the same as described above.

The supporter 440 is a support structure for supporting the camera 450, the lens 470, the prism 481, and the plurality of lights 461, 462 on a position-by-position basis.

The camera 450 plays a role of acquiring the image information for the panel 10 and the functional film 30. As described above, the camera 450 applied to the alignment camera apparatus 400 according to the present embodiment is a single camera. Accordingly, it is advantageous to obtain the alignment image information for obtaining accurate coordinate values of the panel 10 and the functional film 30 by solving the problem of application of the individual camera. An auto focusing mechanism 451 may be mounted on the upper portion of the camera 450.

The lens 470 is a kind of lens barrel provided on one side of the supporter 440 and connected to the camera 450, Aligned image information for the panel 10 and the functional film 30 can be obtained through the lens 470. [

Since the axes of the camera 450 and the lens 470 are different from each other, a prism 481 is provided for correcting the axes. The prism 481 is disposed between the camera 450 and the lens 470 and serves to acquire the alignment image information through the lens 470 disposed in the accumulation manner with respect to the camera 450.

In this embodiment, the first illumination 461 is a coaxial illumination 461 disposed on the prism 481 and disposed coaxially with the lens 470. As this coaxial illumination 461, IR (Infrared Ray) illumination can be applied.

In addition, when the image 450 is captured and acquired by the camera 450, the panel 10 should be irradiated with light. At this time, as described with reference to FIG. 1, the polarizing film 20 is already attached to the panel 10, so that when the general illumination is used, the alignment mark on the panel 10 is not covered by the polarizing film 20. Therefore, at this time, it is necessary to investigate the IR illumination to acquire the alignment marks on the desired panel 10 and utilize the information as the alignment image information. When the first illumination 461 is turned on, the second illumination 462 remains off.

In this embodiment, the second illuminator 462 is a side illuminator 462 coupled to the lower portion of the lens 470 and serving to illuminate the side of the functional film 30 with light. As such side illumination 462, LED (Light Emitting Diode) illumination may be applied.

In addition, in order to capture and acquire the alignment image information for the functional film 30, that is, the transparent mounting film (OCA) for optical use by the action of the camera 450, the optical transparent mounting film (OCA) Since the corners are rounded because they are transparent, a clear edge image is required to obtain the alignment information of this condition. To this end, a side illumination 462 is used. When the second illumination 462 is turned on, the first illumination 461 remains off. An illumination controller 462a is disposed above the side illumination 462. [

Since the different lights such as the coaxial illumination 461 and the side illumination 462 can be seen by a single camera 450 as in the present embodiment, photographing is possible without changing the position of the camera 450. In particular, since the illumination environment can be selectively changed by using different kinds of illumination conditions, optimum position and alignment coordinates can be obtained.
