Description

Functional film attaching system

The present invention relates to a functional film attachment system, and more particularly, foreign matter on the functional film side is transferred to the adhesive sheet by effectively removing the foreign matter on the functional film in advance through a cleaning operation of the functional film. The present invention relates to a functional film attachment system that can effectively prevent the adhesion from being weakened.

Recently, with the rapid development of the electronic display industry, OLED (Organic Light Emitting Diodes) technology is also rapidly developing. OLED is divided into passive PMOLED and active AMOLED depending on the driving method.

In manufacturing such OLEDs, various kinds of functional films such as polarizer films and optically clear adhesive films (OCAs) are used.

The polarizing film is attached to a panel, which is an object, to polarize light, and the optically 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.

In the past, a roll-to-stage method or a drum applied with a set table was applied as a technology for attaching a functional film such as a polarizing film or an optical transparent mounting film to an object panel. Drum to Stage was common.

In the former roll-to-stage method, a panel that is an object is disposed on a set table, and an attach roller is attached to the panel while the attach roller rotates. This method is an overhang phenomenon of the film. Due to the error, there is a problem in that a high degree of attachment is limited.

For reference, in the roll-to-stage method, due to its characteristics, the functional film is not properly adsorbed on the attach roller, and sagging is likely to occur. As a result, alignment with the panel is inevitably misaligned. Is generated, which is called an overhang phenomenon.

In contrast, the latter drum-to-stage method adsorbs a functional film on the surface of the drum and attaches the functional film to the panel according to the rotational motion of the drum. The pad may cause damage due to contact with the pad, and also due to the limitation of the vacuum area of the drum, there are other problems in changing various panel sizes.

As described above, the roll-to-stage method and the drum-to-stage method have been mainstream as a method of attaching a functional film to a panel. However, each method generates a problem as described above. An alternative method is proposed, and many companies are currently developing it.

This method is to pre-adhesive a functional film such as a polarizing film to a pressure-sensitive adhesive sheet having a weak viscosity, then arrange a functional film on a panel, and then press the pressure-sensitive adhesive sheet to attach the functional film to the panel. After the functional film is attached to the panel, the adhesive sheet is peeled off the functional film.

In order to attach the functional film to the panel in such a manner, that is, to attach the optical transparent mounting film to the panel with the polarizing film, a suitable functional film attachment system is required.

On the other hand, the functional film attachment system as described above has a manner in which the functional film is attached to the panel using the pressure of the adhesive sheet after attaching the functional film to the adhesive sheet as described above.

At this time, if the foreign matter is attached to the adhesive sheet that plays a major role, that is, the foreign matter attached to the functional film is transferred to the adhesive sheet and the foreign matter adheres to the adhesive sheet, the adhesive force of the adhesive sheet is bound to fall. The adhesive force is the adhesion force, and the adhesion force is the usage amount of the functional film attachment system by the number of attachment times.

Considering that the foreign material transferred to the adhesive sheet weakens the adhesive force of the adhesive sheet and thus reduces the amount of use of the functional film attaching system, the number of replacement of the adhesive sheet increases, and thus the replacement labor and cost are inevitably considered. There is a need for a functional film cleaning apparatus for preventing foreign substances on the side from being transferred to the adhesive sheet to weaken the adhesive force of the adhesive sheet.

However, in some cases, the functional film 30 without the polarizing film 20 will be described. It may be attached to the panel 10 alone, all of these matters should be within the scope of the present invention.

2 is a block diagram of a functional film attachment system according to an embodiment of the present invention.

The functional film attachment system according to the present embodiment can easily supply the functional film 30 and the panel 10 to the film attachment work line unit 300 through an efficient structure to attach a functional film 30 to a series of controls. 2 may be simpler than before, and the system may be compact and simplified to reduce a foot print, and may be implemented as a system as shown in FIG. 2.

In particular, in the present embodiment, the functional film cleaning apparatus 600 (see FIGS. 18 to 21) is applied as described later in detail, so that foreign matters on the functional film 30 through the cleaning operation of the functional film 30, in particular, By effectively removing the foreign matter on the second protective film 42 in advance, the foreign matter on the side of the functional film 30 is transferred to the adhesive sheet 110 to effectively prevent the adhesive force of the adhesive sheet 110 from being weakened.

This functional film cleaning device 600 may be applied to one configuration of the system as shown in FIG. That is, in the functional film attachment system according to the present embodiment, the functional film 30 and the panel 10 are supplied from both sides, but the film attachment work line part 300 forming a line to which the functional film 30 is attached to the panel 10. And a functional film attaching apparatus 100, a protective film peeling apparatus 200, a functional film cleaning apparatus 600, and an alignment camera apparatus 400 on or around the film attaching work line unit 300. Has a structure that is arranged.

In addition, the functional film attachment system according to the present embodiment includes a film magazine device 500, a film handling robot 310, a film checker 360, a panel loading stage 330, a plasma device 800, and a panel turn stage 340. And the panel unloading stage 350 are mounted for each position.

The film stage 380 on which the functional film 30 is mounted and moved, and the panel stage 700 on which the panel 10 is mounted and moved are provided on the film work line 300.

In the present exemplary embodiment, the film stage 380 and the panel stage 700 are provided in dual, respectively, thereby improving productivity due to a decrease in tact time. However, the film stage 380 and the panel stage 700 may be applied one by one.

Hereinafter, referring to the corresponding drawings for the functional film attaching apparatus 100, the protective film peeling apparatus 200, the functional film cleaning apparatus 600, and the alignment camera apparatus 400 among the detailed components constituting the functional film attaching system. This will be described in detail.

For reference, the remaining components, that is, the film magazine device 500, the plasma device 800, the panel stage 700, the film handling robot 310, the film checker 360, the panel loading stage 330, and the panel turn stage ( Detailed description of the configuration of the 340, the panel unloading stage 350, and the film stage 380 and the like will be omitted, and will be replaced with the description of the operation to be described later.

First, the functional film attaching apparatus 100 is provided on the film attaching work line unit 300 (see FIG. 2), as shown in detail in FIGS. 2 to 9 as well as in FIG. 2, and substantially on the panel 10. It serves to attach the functional film (30).

The functional film attaching device 100 is provided on the attachment device main body 120 and the attachment device main body 120 to attach the functional film 30 to the panel 10 using the adhesive sheet 110 (see FIG. 4). It may include a functional film attachment portion 150 to.

Attachment device body 120 forms an appearance structure of the functional film attachment device 100 according to this embodiment. The attachment device main body 120 includes structures such as the adhesive sheet 110, the sheet mounting unit 130, the functional film attaching unit 150, and the like, by position.

One side of the attachment device main body 120 is provided with a main body driving unit 121. The main body driving unit 121 serves to drive up and down the entire attachment device main body 120. Since the attachment device main body 120 is spaced apart from the upper portion of the panel stage 700, the main body driving unit 121 may be provided to adjust the gap thereof.

In the present embodiment, the adhesive sheet 110 is used to attach 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 description.

The adhesive sheet 110 applied to the present embodiment is a medium used to attach the functional film 30 to the panel 10. That is, in this embodiment, the functional film 30 is not attached to the panel 10 as it is, but the functional film 30 is first adhered to the adhesive sheet 110 as shown in FIGS. 6 to 9, and then the functional film 30 is applied. After aligning the panel 10 with each other, the pressure-sensitive adhesive sheet 110 is pressed to allow the functional film 30 to be attached to the panel 10.

As described above, when the functional film 30 is attached to the panel 10 via the adhesive sheet 110, a roll to stage method or drum applied with a conventional set table may be used. Unlike the drum-to-stage method, it has the advantage of excellent adhesion efficiency and quality.

However, when the adhesive sheet 110 is applied, an engineering plastic-based adhesive sheet, an air pocket sheet, a porous sheet, etc. are simply applied due to high elongation. It is impossible to cope with the attachment degree, short life, high running cost and frequent replacement cycles cause down time.

In this embodiment, this problem is solved by presenting the adhesive sheet 110 having the following innovative structure. As shown in FIGS. 4 and 5, the adhesive sheet 110 applied to the functional film attaching apparatus 100 according to the present embodiment has an adhesive layer 111, a reinforcing layer 114, and a cushion disposed therebetween. The layer 112 and the adhesive layer 113 may be included. As illustrated in FIG. 5, the adhesive layer 111, the cushion layer 112, the adhesive layer 113, and the reinforcement layer 114 may be sequentially arranged.

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

For reference, van der Waals forces refer to forces acting between electrically neutral molecules that do not have quasi electrons. In particular, it refers to a manpower that operates relatively remotely. Van der Waals forces arise as a result of dispersing forces, and the van der Waals forces explain the forces acting between rare gas atoms and the factors in which molecular crystals of hydrocarbons such as benzene are formed. In addition, van der Waals force means the intrinsic force necessary to explain the phenomenon such as physical adsorption, such as agglomeration, adhesion of the liquid and the present embodiment.

In summary, van der Waals forces are extremely weak electrostatic attraction that acts only at very short distances between electrically neutral molecules, collectively referred to as electrical forces acting between covalent molecules.

In particular, physical adhesion is possible without a separate power through the force of the ions, the functional film 30 can be easily adhered because the adhesive layer 111 is manufactured based on such van der Waals forces, May be peeled off. That is, since a weak viscosity is formed in the adhesive layer 111, the adhesive layer 111 may be adhered to the functional film 30. After the functional film 30 is attached to the panel 10, the adhesive layer 111 may be adhered to the adhesive layer 111. The functional film 30 can be easily peeled off, that is, peeled off.

On the other hand, in the application of such an adhesive layer 111, if only the adhesive layer 111 is applied to the sheet can perform the desired process well in the early stage, but the adhesive layer 111 will increase due to high adhesion pressure during repeated use However, when the adhesive layer 111 is increased, it is inevitably impossible to cope with a high degree of adhesion of the product.

Thus, the reinforcing layer 114 is provided on the adhesive sheet 110 applied to the functional film attaching apparatus 100 according to the present embodiment so that such a phenomenon does not occur. The reinforcing layer 114 is connected to the adhesive layer 111 but serves to reinforce the adhesive layer 111 so that the elongation of the adhesive layer 111 is not increased. In this embodiment, the reinforcement layer 114 is applied to a stainless steel thin plate, and reinforces while supporting the adhesive layer 111 with a larger area than the adhesive layer 111 as shown in FIG. 4. Since the reinforcement layer 114 is applied to the stainless steel sheet, it is advantageous to match the elongation.

As such, when the reinforcement layer 114 is further applied to the adhesive sheet 110, the elongation can be lowered as close to zero as possible to a high degree of adhesion, and the durability can be improved. As a result, the service life can be extended, which not only reduces the running cost, but also reduces the down time due to the long replacement cycle.

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 buffer 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 attachment roller 151 which will be described later.

The adhesive layer 113 serves to bond the cushion layer 112 and the reinforcement layer 114. In fact, since the adhesive layer 111 has a weak viscosity and can stick with the cushion layer 112, the adhesive layer 113 only needs to be interposed between the cushion layer 112 and the reinforcing layer 114. Of course, if necessary, the adhesive layer 113 may also be reapplied between the adhesive layer 111 and the cushion layer 112, which should also be included in 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, and a cushion layer 112 and an adhesive layer 113 disposed therebetween. The thickness of the 113 and the cushion layer 112 and the thickness of the reinforcing layer 114 may be the same, and the thickness of the adhesive layer 111 may be greater than twice the thickness of the reinforcing layer 114. For example, when the thickness of the adhesive layer 111 is 300 μm, the thickness of the reinforcement layer 114 may be 50 μm, and the sum of the thickness of the cushion layer 112 and the thickness of the reinforcement layer 114 may be 50 μm. . This is advantageous because it is substantially thick because the portion to which the functional film 30 is adhered is the adhesive layer 111, and the reinforcement layer 114 must be thin to be flexible. However, the scope of the present invention is not limited to the numerical values thereof.

As described above, the adhesive sheet 110 based on the van der Waals force described above is preferably applied to the functional film attaching device 100 according to the present embodiment, but is not necessarily the case. That is, it does not matter even if it uses the adhesive sheet (not shown) to which the general usual adhesive substance was apply | coated. Therefore, the scope of the present invention is not limited to these matters.

Meanwhile, first and second sheet clamps 116 and 117 supporting both ends of the adhesive sheet 110 at both ends of the adhesive sheet 110 so that the adhesive sheet 110 may be mounted at a corresponding position of the attachment device main body 120. Is combined. The adhesive sheet 110 may be mounted on the sheet mounting unit 130 via the first and second sheet clamps 116 and 117.

The sheet mounting unit 130 is provided on one side of the attachment device main body 120 to form a place where the adhesive sheet 110 is mounted. As described above, the first and second sheet clamps 116 and 117 are coupled to both ends of the adhesive sheet 110, and the adhesive sheet (the first and second sheet clamps 116 and 117 are mounted on the sheet mounting unit 130). 110 may be installed.

The seat mounting unit 130 is provided on one side of the attachment device main body 120, and is provided on the first clamp mounting support 131 for supporting the first seat clamp 116 to be mounted, and on the other side of the attachment device main body 120. A second clamp mounting support 132 may be provided to support the second sheet clamp 117 to be mounted thereon.

Functional film attachment device 100 according to this embodiment is equipped with a functional film attachment portion 150 as described above. The functional film attaching part 150 is provided in the attaching device main body 120 adjacent to the sheet mounting part 130, and after the functional film 30 is adhered to the adhesive sheet 110 in an unfolded state, the adhesive sheet 110 is provided. ) To attach the functional film 30 to the panel 10.

In other words, the functional film attaching part 150 first adheres the functional film 30 to the adhesive sheet 110 as shown in FIGS. 6 to 9, and then the panel for the functional film 30 based on the functional film 30. After aligning the relative positions of the 10, the pressure-sensitive adhesive sheet 110 is pressed to allow the functional film 30 to be attached to the panel 10. After the functional film 30 is attached to the panel 10, the adhesive sheet 110 is peeled off, that is, detached from the functional film 30.

The functional film attachment part 150 which plays such a role is the attachment roller 151, the backup roller 152, and the sheet release roller 153 which are connected to one body by the roller support module 155, and the roller support module ( The module may include a module up / down driving unit 160 for up / down driving 155 and a module driving unit 170 for driving the roller support module 155.

The attachment roller 151 may allow the functional film 30 to adhere to the adhesive layer 111 of the adhesive sheet 110 as shown in FIGS. 6 to 7 or the functional film 30 to the panel 10 as illustrated in FIGS. 8 to 9. It is a roller which is pressed and moved on the adhesive sheet 110 so that it may adhere.

In other words, the attachment roller 151 presses the adhesive sheet 110 from one side to the other side while being rotated in the reinforcing layer 114 on the adhesive sheet 110. Therefore, a process of adhering the functional film 30 to the adhesive layer 111 of the adhesive sheet 110 may be performed as shown in FIG. 6 to FIG. 7, and the functional film 30 to the panel 10 as illustrated in FIG. 8. This attaching process can proceed.

The backup roller 152 is a roller that is external to the attachment roller 151 and supports the rotation of the attachment roller 151. The backup roller 152 may have a diameter larger than that of the attachment roller 151. Due to the action of the backup roller 152, the attachment roller 151 is attached to the adhesive layer of the adhesive sheet 110 as shown in FIGS. The functional film 30 is adhered to the 111 or the process of attaching the functional film 30 to the panel 10 as shown in FIGS. 8 to 9 may be well performed.

The sheet release roller 153 is a roller having a function of detaching the adhesive sheet 110 from the functional film 30 when the attachment of the functional film 30 to the panel 10 is completed as shown in FIG. 9. The sheet release roller 153 is disposed below the adhesive sheet 110 at a position higher than the attachment roller 151. Since the sheet release roller 153 is disposed below the adhesive sheet 110, when the sheet release roller 153 is up, the adhesive sheet 110 may be peeled off, that is, separated from the functional film 30. .

The attachment roller 151, the backup roller 152, and the sheet release roller 153 described above are supported by the roller support module 155 as a body. Accordingly, when the roller support module 155 is up, the attachment roller 151, the backup roller 152, and the sheet release roller 153 may also be up together, and the roller support module 155 may be down ( When down, the attachment roller 151, the backup roller 152, and the sheet release roller 153 may also be down together.

The operation of the driving unit 170 may be controlled.

Meanwhile, as described above, in the adhesive sheet 110, a first sheet clamp 116 supporting one end thereof is mounted on the first clamp mounting support 131, and an adhesive sheet 110 supports the other end of the adhesive sheet 110. The second seat clamp 117 may be installed in a form in which the second clamp mounting support 132 is mounted. In this case, a plurality of sheet idle rollers 134 are provided to guide the pressure-sensitive adhesive sheet 110 extending between the first clamp mounting support 131 and the second clamp mounting support 132.

The plurality of sheet idle 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 the present embodiment, the plurality of sheet idle 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 are applied as a non-power free rotating roller. do.

Although the adhesive sheet 110 is guided by the action of the sheet idle rollers 134 as described above, since the adhesive sheet 110 is pressed toward the panel 10 when the functional film 30 is attached, the operation is repeatedly performed. There is a fear that the initial tension of the adhesive sheet 110 is misaligned. Thus, the seat tension holding unit 140 is provided.

That is, since the functional film attaching device 100 attaches the functional film 30 to the panel 10 by using the adhesive sheet 110, the adhesive sheet 110 directly adheres to the functional film 30. Depending on the degree of stretching or shrinkage of the 110 may affect the functional film 30 attached to the panel 10.

Therefore, the functional film 30 must be pressurized to the panel 10 while maintaining the tension of the adhesive sheet 110 in a proper state, that is, at a level required in the process, in accordance with the stretching amount of the functional film 30. The adhesion quality of the film 30 can be improved, and for this purpose, the sheet tension maintaining unit 140 is provided.

The seat tension maintaining unit 140 is provided in the attachment device 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. The seat tension holder 140 may include an interactive head cylinder unit 141 and a tail cylinder unit 143.

The head cylinder unit 141 is connected to one end region of the adhesive sheet 110, that is, the first clamp mounting support 131 of the sheet mounting unit 130, and when the functional film 30 is attached to the panel 10. It works.

The head cylinder unit 141 is provided in the first support connecting portion 141a connected to the first clamp mounting support 131, the attachment device main body 120, and the first support connection portion 141a, and the attachment device main body.

The tail cylinder unit 143 is provided on the second support connecting portion 143a connected to the second clamp mounting support 132, the attachment device main body 120 and the second support connection part 143a, and the attachment device main body. A second sliding guide 143b for slidingly moving the second support connecting portion 143a with respect to 120 and a tail cylinder 143c coupled to the second support connecting portion 143a may be included.

As a result, when attaching the functional film 30 to the panel 10 by using the adhesive sheet 110, as shown in Figs. 8 and 9, the head cylinder unit 141 and the tail cylinder forming the seat tension holding unit 140 By the unit 143 acting, the tension of the adhesive sheet 110 can be maintained at a constant level required in the process. That is, since the head cylinder 141c and the tail cylinder 143c provide a constant pressure, the tension of the initially set value can be maintained as it is, and thus the adhesive sheet 110 is not excessively stretched or shrunk. Thus, since the pressure-sensitive adhesive sheet 110 pressurizes the functional film 30 toward the panel 10, the adhesion quality of the functional film 30 may be improved. In particular, even if the functional film 30 is thin, the adhesion quality can be kept constant.

Next, the protective film peeling apparatus 200, as shown in FIGS. 1 and 2, as shown in FIGS. 10 to 17, the first and second protective films 41 and 42 provided on both surfaces of the functional film 30. ), That is, peels off. In the case of FIGS. 14 to 17 illustrating the operation of the protective film peeling apparatus 200, the peeling of the first protective film 41 from the functional film 30 is illustrated. Even in this case, it can be peeled off. However, in the case of the first protective film 41, the protective film peeling device 200 works under the functional film 30 to peel off (upper left part of FIG. 2) while in the case of the second protective film 42. After the functional film 30 is attached to the panel 10, the protective film peeling apparatus 200 works on the upper part of the functional film 30, and peels off (lower left part of FIG. 2). However, the scope of the present invention is not limited to these matters.

A plurality of protective film peeling apparatus 200 is disposed on one side of the film attachment work line unit 300 as shown in FIG. 2, and the first protective film 41 and the second protective film 42 are sequentially disposed at a corresponding position. Peel off (remove).

The protective film peeling apparatus 200 is a film peeling adhesive rotary roller 241 adhered to the surface of the first protective film 41, for example, to peel the first protective film 41 on the surface of the functional film 30. And a film collecting part 260 disposed adjacent to the articulated robot 210 and collecting the peeled first protective film 41.

The articulated robot 210 is connected to the robot body 220 and the robot body 220 which is supported on the installation surface, and has at least three joint shafts 230 and at the distal end of the articulated arm 230. Connected but includes a robot head 240 is mounted on the adhesive peeling roller 241 for peeling.

In the present embodiment, the six-axis articulated robot 210 is applied. That is, the robot head 240 peels 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, and then the film collecting part ( Discard at 260). When the articulated robot 210 is applied, the compact and efficient structure can be used to reduce the footprint, as well as control the speed, position, and curve movement, thereby remarkably inducing the occurrence of peeling error and film removal. Can be reduced. In addition, the application of a separate additional equipment for the secondary peeling or collection of the peeled first protective film 41 is not necessary or can be simplified to a minimum. For reference, in the case of the present embodiment, the 6-axis articulated robot 210 is applied, but it is sufficient if more than three axes.

The adhesive peeling roller 241 for peeling the film is a roller provided on one side of the robot head 240, and serves to partially peel off the first end of the first protective film 41 from the functional film 30 as shown in FIGS. 14 to 15. Do it. Since the adhesive material is coated on the surface of the adhesive peeling roller 241 for peeling off the film, the adhesive peeling roller 241 for peeling off the film comes in contact with the end of the first protective film 41 and then rotates in FIG. 14. As shown in FIG. 15, a part of the first protective film 41 may be slightly dried and attached to the adhesive rotating roller 241 for peeling off the film.

The robot head 240 is provided with a film clamp 242 and a clamp actuator 244 for interaction with the adhesive peeling roller 241 for peeling the film.

The film clamp 242 is disposed adjacent to the adhesive peeling roller 241 for peeling off the robot head 240, and clamps the first protective film 41 together with the adhesive peeling roller 241 for peeling off the film. It plays a role. At the end of the film clamp 242 is formed a curved portion 243 having the same curvature as the outer circumferential surface of the adhesive peeling roller 241 for peeling film. Accordingly, the first protective film 41 that is peeled off may be clamped without error between the adhesive rotating roller 241 for peeling the film and the curved portion 243 of the film clamp 242.

The clamp actuator 244 serves to drive or close the film clamp 242 to the adhesive rotating roller 241 for peeling the film. The clamp actuator 244 may be a motor or cylinder structure.

Thus, after the portion of the first protective film 41 is slightly dried and attached to the adhesive peeling roller 241 for peeling as shown in FIG. 14 to 15, the clamp actuator 244 is operated as shown in FIG. The curved surface portion 243 of 242 is to be pressed against the outer surface of the adhesive rotating roller 241 for peeling film. Then, the partially peeled first protective film 41 may be clamped between the adhesive rotating roller 241 for peeling the film and the curved portion 243 of the film clamp 242. By operating the articulating robot 210, the first protective film 41 may be completely peeled off from the functional film 30.

The robot head 240 is provided with a first film sensor 245 that detects whether the first protective film 41 is clamped to the film clamp 242. After the first film 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. You can. Therefore, even though the first protective film 41 is not clamped between the adhesive peeling roller 241 for peeling the film and the film clamp 242, an error that the articulated robot 210 is operated may be prevented.

In addition to such configurations, that is, components for peeling and clamping the first protective film 41, the robot head 240 is further equipped with a suction unit 246. The adsorption unit 246 is provided at one side of the robot head 240 and includes a plurality of adsorption pads 247 for adsorbing the panel 10 or the functional film 30 in a vacuum. The adsorption unit 246 may serve to adsorb and move the panel 10, the functional film 30, or other subsidiary materials.

Referring to FIG. 10 again, the film collecting unit 260 may include a film collecting container 261 and a film collecting container 261 in which the first protective film 41 peeled off from the panel 10 or the functional film 30 is collected. Adsorption combined blowing unit 262 provided in the inlet region.

The adsorption combined blowing unit 262 is provided at the inlet region of the film container 261, and absorbs the first protective film 41 collected in the film container 261 under the action of the articulated robot 210. It plays a role of blowing.

On the other hand, the protective film peeling apparatus 200 according to the present embodiment is further equipped with a second film sensor 263 to interact with the controller (not shown). The second film sensor 263 is provided in the adsorption blowing unit 262, and detects whether the first protective film 41 from the articulated robot 210 is disposed in the adsorption double blowing unit 262. It plays a role. The controller controls the operation of the film clamp 242 and the combined suction unit 262 based on the detection signal of the second film detection sensor 263.

Accordingly, when the articulated robot 210 inserts the peeled first protective film 41 toward the film container 261, the second film sensor 263 detects whether the first protective film 41 is present. Send the information to the controller. When the first protective film 41 is present, the first protective film 41 may be adsorbed to the dual adsorbing blowing unit 262 by the vacuum action of the dual adsorbing 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 returns to its original position, the first protective film 41 may be collected while falling back to the bottom of the film container 261 due to the blowing action of the combined suction unit 262 by the controller. .

Next, the functional film cleaning apparatus 600 is provided on one side on the film attachment work line unit 300, as shown in FIGS. 18 to 21 including FIG. 2, and particularly, a protective film of the functional film 30. In addition, the second protective film 42 serves to remove foreign materials remaining on the cleaning surface. This is because the second protective film 42 of the functional film 30 adheres to the adhesive sheet 110.

As described above, no matter how clean the adhesive sheet 110, if there is foreign matter on the second protective film 42 of the functional film 30 supplied from the outside, there is no choice but to transfer to the adhesive sheet 110. As such, when foreign matter adheres to the adhesive sheet 110, the adhesive force of the adhesive sheet 110 is weakened, and thus the amount of attachment work of the functional film 30 is reduced. It must be generated. Therefore, if the foreign material remaining on the second protective film 42 of the functional film 30 can be removed in advance to clean the second protective film 42 of the functional film 30, the adhesive sheet 110 is substantially semi-permanent. Can also be used as To this end, the functional film cleaning device 600 is provided.

The functional film cleaning apparatus 600 includes a cleaning apparatus main body 610, a cleaning roller 620 and a transition roller 630 rotatably provided on the cleaning apparatus main body 610. The functional film cleaning apparatus 600 is shown in FIG. 2, the functional film cleaning apparatus 600 is provided to be fixed to one side on the film attachment work line unit 300. Therefore, the functional film 30 may be seated on the film stage 380 and then cleaned while being moved toward the functional film cleaning device 600 through the film stage 380.

The cleaning apparatus main body 610 forms an external structure of the functional film cleaning apparatus 600. The cleaning roller 620 and the transfer roller 630 and the structures supporting them are mounted on the cleaning apparatus main body 610 by position.

The cleaning roller 620 is rotatably provided in the main body of the cleaning apparatus 610, and serves to remove and clean foreign substances remaining on the second protective film 42 of the functional film 30.

The cleaning roller 620 has a predetermined adhesive force as a non-power free rotating 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 foreign matter on the second protective film 42 may be removed. It may be transferred to the cleaning roller 620.

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

In this embodiment, the transfer roller 630 also has a predetermined adhesive force as a non-power free rotating roller. At this time, the adhesive force of the transfer roller 630 is greater than that of the cleaning roller 620, and the size of the transfer roller 630 is larger than that of the cleaning roller 620.

Therefore, the foreign matter remaining on the second protective film 42 is first transferred to the cleaning roller 620, and then secondly transferred to the transfer roller 630, the foreign matter is transferred to the transfer roller 630. It can remain as it is. In particular, since the size of the transfer roller 630 is large, a large amount of foreign matter can be adsorbed and retained.

The first roller support part 641 and the second roller support part 642 are provided in the functional film cleaning apparatus 600 so that the cleaning roller 620 and the transition roller 630 may be rotated. The first roller support part 641 is a structure for rotatably supporting the cleaning roller 620, and the second roller support part 642 is a structure for rotatably supporting the transition roller 630. At this time, the first and second roller supports 641 and 642 are connected to one body by the connecting frame 650.

The functional film cleaning apparatus 600 further includes a frame up / down driving unit 660. The frame up / down driving unit 660 is provided in the cleaning apparatus main body 610 and the connection frame 650, and serves to drive the connection frame 650 up / down with respect to the cleaning apparatus main body 610. Do it. Since the connecting frame 650 is up / down by the frame up / down driving unit 660, the gap between the cleaning roller 620 and the second protective film 42 may be well aligned in the process.

The frame up / down driving unit 660 includes a cylinder body 671 coupled to the cleaning apparatus body 610, and a cylinder rod 672 connected to the cylinder body 671 and having an end coupled to the connecting frame 650. And a guide 680 provided between the cylinder 670, the cleaning apparatus main body 610, and the connection frame 650 to guide the up / down driving of the connection frame 650.

At this time, the guide 680 is a cleaning device body between the pair of main guide portion 681 and the pair of main guide portion 681 disposed on both sides between the cleaning device body 610 and the connecting frame 650. A plurality of sub guide parts 682 connected to the 610 and the connecting frame 650 may be included. The guide 680 is applied to the main guide part 681 and the sub guide part 682 so that the up / down operation of the connecting frame 650 by the frame up / down driving part 660 is more stably performed. Can be elicited.

Next, the alignment camera apparatus 400 serves to obtain alignment image information about the panel 10 and the functional film 30 as shown in FIGS.

As described above, in order to achieve the performance of the high accuracy of the adhesion degree, it is necessary to obtain the alignment image information for obtaining the accurate coordinate values of the panel 10 and the functional film 30, based on this The functional film 30 should be attached. In this case, if the camera for acquiring the alignment image information for the panel 10 and the camera for acquiring the alignment image information for the functional film 30 are separately provided, the amount of deviation may occur in camera synchronization. This can make it virtually impossible to cope with high-precision products.

Therefore, it is advantageous to apply the alignment camera device 400 to which a single camera 450 is applied as in the present embodiment. Of course, the alignment camera device 400 according to the present embodiment, as described later, applies a single camera 450 and a plurality of illuminations 461 and 462 of different light properties in a compact and efficient manner. By acquiring alignment image information on the film 30, it is possible to cope with a high-precision product.

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

The module frame 410 is a structure fixed to one side on the film attachment work line unit 300, and supports the unit camera modules 420. After the initial setting of the position of the unit camera module 420, since the position of the camera 450 provided in the unit camera module 420 is fixed without moving, accurate coordinate values of the panel 10 and the functional film 30 are fixed. It is advantageous to obtain.

One unit camera module 420 of the plurality of unit camera modules 420 is driven to approach or spaced apart from the other unit camera module 420, which is in charge of the module driver 430. The module driver 430 may be implemented by a combination of a motor and a ball screw. The pair of unit camera modules 420 are driven or approached apart from each other by the module driving unit 430, so that the pair of unit camera modules 420 may be commonly coped with the panel 10 and the functional film 30 having different sizes.

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

The supporter 440 is a support structure that supports the camera 450, the lens 470, the prism 481, and the plurality of lights 461 and 462 for each location.

The camera 450 acquires alignment image information about the panel 10 and the functional film 30. As will be described repeatedly, the camera 450 applied to the alignment camera device 400 according to the present embodiment is a single camera. Therefore, it is advantageous to obtain alignment image information for obtaining accurate coordinate values of the panel 10 and the functional film 30 by solving the problem of application of individual cameras. An auto focusing mechanism 451 may be mounted on an upper portion of the camera 450.

The lens 470 is provided on one side of the supporter 440 and is connected to the camera 450, but is a kind of barrel disposed on an axis different from the camera 450. Aligned image information about the panel 10 and the functional film 30 may be obtained through the lens 470.

Since the axis of the camera 450 and the lens 470 are different, a prism 481 is provided to correct this. The prism 481 is disposed between the camera 450 and the lens 470 and serves to acquire alignment image information through the lens 470 biaxially disposed with respect to the camera 450. This need not be the case, but additional side illuminations 483 may be provided on the sides of the prism 481.

Meanwhile, the plurality of lights 461 and 462 are light sources that emit light toward the panel 10 and the functional film 30 when the camera 450 captures alignment image information about the panel 10 and the functional film 30. . In the present embodiment, the plurality of illuminations 461 and 462 are applied with different properties of the irradiated light.

That is, the plurality of lights 461 and 462 are positioned differently from the first light 461 and the first light 461 irradiated toward the panel 10 when the camera 450 photographs the alignment image information on the panel 10. When the camera 450 captures the alignment image information on the functional film 30, the camera 450 is irradiated toward the functional film 30, but the second illumination 462 having different light properties from the first illumination 461 is provided. It may include.

In the present embodiment, the first illumination 461 is a coaxial illumination 461 disposed on the prism 481 but coaxially disposed with the lens 470. Infrared ray (IR) illumination may be applied as the coaxial illumination 461.

In this regard, when an image of the panel 10 is to be acquired by capturing alignment image information by the action of the camera 450, light should be irradiated to the panel 10. In this case, as described with reference to FIG. 1, since the polarizing film 20 is already attached to the panel 10, when the general lighting is used, the alignment mark on the panel 10 is not hidden by the polarizing film 20. Therefore, in this case, the alignment mark on the desired panel 10 needs to be irradiated with IR illumination to be used as alignment image information. When the first light 461 is turned on, the second light 462 remains off.

In the present embodiment, the second illumination 462 is coupled to the lower portion of the lens 470, and is a side illumination 462 that serves to irradiate light to the side of the functional film 30. As the side lights 462, LED (Light Emitting Diode) lighting may be applied.

In this regard, when the image of the functional film 30, that is, the optical transparent mounting film (OCA), is acquired by capturing the alignment image information by the action of the camera 450, the optical transparent mounting film (OCA) Since the corners are also rounded because they are transparent, a clear edge image is required to obtain aligned image information under such a condition. For this purpose, side lighting 462 is used. When the second light 462 is turned on, the first light 461 remains off. The lighting controller 462a is disposed above the side lighting 462.

As in the present embodiment, since different lights, that is, the coaxial light 461 and the side light 462, can be viewed as a single camera 450, photography can be performed without changing the position of the camera 450. In particular, since the lighting environment can be selectively changed through different kinds of lighting conditions, optimal position and alignment coordinates can be obtained.

Briefly look at the operation of the functional film attachment system of FIG.

The plurality of functional films 30 loaded on the film magazine device 500 are taken out one by one through the interaction of the film magazine device 500 and the film handling robot 310, and then on the film attachment work line unit 300. It is seated on the film stage 380 provided on one side.

In this process, the handling robot 310 may check whether the film is supplied one by one through the film checker 360.

The functional film 30 seated and supported on the film stage 380 is moved to the functional film cleaning device 600 while moving on the film attachment work line unit 300 by the action of the film stage 380, and the functional film cleaning device. At 600, the foreign material on the second protective film 42 (see FIG. 1) is cleaned.

The functional film 30 having the foreign matter on the second protective film 42 cleaned reaches the protective film peeling apparatus 200, and the first protective film 41 is peeled off from the protective film peeling apparatus 200.

Subsequently, after the functional film 30 reaches the alignment camera apparatus 400, alignment image information of the functional film 30 is photographed by the action of the alignment camera apparatus 400 of the functional film 30. . Thereafter, the functional film 30 is moved to the functional film attaching device 100 and adhered to the adhesive sheet 110 on the functional film attaching device 100 to stand by.

On the other hand, in parallel with this operation, the panel 10 is supplied from the opposite side of the film magazine device 500.

After the panel 10 is loaded in the panel loading stage 330, the panel turn stage 340 is turned 180 degrees. The panel handling robot 320 then moves the panel 10 to the panel stage 700 provided on the other side on the film attachment work line unit 300.

After the panel 10 reaches the alignment camera device 400 while moving on the film attachment work line unit 300 by the action of the panel stage 700, the panel 10 is operated by the action of the alignment camera device 400. Aligned image information about is captured. Then, it is moved to the lower portion of the functional film attachment device 100.

At this time, since the functional film 30 is already adhered to the adhesive sheet 110 of the functional film attaching device 100, the functional film 30 is based on the alignment image information of the functional film 30 and the panel 10. The relative position of the panel 10 is aligned based on the reference. Alignment work for the panel 10 proceeds at the panel stage 700 while the panel 10 is moved to the functional film attachment device 100. Therefore, the tact time can be reduced.

When the alignment of the panel 10 with respect to the functional film 30 is completed, the functional film 30 is attached to the panel 10 through the functional film attaching device 100. That is, the functional film 30 is attached to the panel 10 through the above-described action of FIGS. 8 and 9.

Thereafter, the panel 10 having the functional film 30 attached thereto is moved to the protective film peeling apparatus 200 through the panel stage 700 so that the second protective film 42 is peeled off by the protective film peeling apparatus 200. Then, it is taken out of the system through the panel unloading stage 350. The product taken out as described above is a product in which the functional film 30 is attached to the panel 10.
