Description

Functional film attaching system {System for attaching film to panel}

The present invention relates to a functional film attaching system, and more particularly, to a functional film attaching system capable of further improving production capacity.

Recently, as the electronic display industry has rapidly developed among the semiconductor industry, the flat panel display (FPD) has also continued to develop. Flat panel displays include liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting diodes (OLEDs).

Among flat panel displays, OLED is divided into passive type PMOLED and active type AMOLED according to the driving method.

AMOLED is a self-luminous display, which has the advantages of faster response speed, natural color, and less power consumption than conventional displays. In addition, AMOLED can realize the technology of a flexible display when applied to a flexible panel that is thin and easily bent, not a glass panel.

When manufacturing such an OLED, various kinds of functional films, such as functional films such as polarizer films, may be used. The polarizing film is attached to a panel, which is an object, and serves to polarize light.

On the other hand, in the past, as a technique for attaching a functional film such as a polarizing film to a panel as an object, a roll-to-stage method using a set table or a drum-to-drum using a drum Stage) method was common.

The former roll-to-stage method is a method in which a panel as an object is disposed on a set table, and the attachment roller is rotated to attach a functional film to the panel, which is due to overhang of the film. Due to the error caused, there is a problem that there is a limit to the implementation of high adhesion.

For reference, the roll-to-stage method has a high probability that the functional film is not properly adsorbed to the attachment roller part and sagging phenomenon is generated, and this causes the alignment with the panel to be misaligned, leading to error in attachment. Occurs, which is called an overhang phenomenon.

On the other hand, the latter drum-to-stage method is a method in which a functional film is attached to a panel according to the rotational motion of the drum by adsorbing a functional film on the surface of the drum. The pad may cause damage due to contact, and there are other problems in that various panel sizes are changed due to limitations in the vacuum area of the drum.

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 so far, but each method uses an adhesive sheet in that it causes various problems as described above. The method is proposed as an alternative.

In this method, after attaching a functional film such as a polarizing film to a pressure-sensitive adhesive sheet in advance, a functional film is placed on the panel, and then the pressure-sensitive adhesive sheet is pressed to attach the functional film to the panel. After the functional film is attached to the panel, the pressure-sensitive adhesive sheet is peeled off the functional film, and there is a need to develop a functional film attachment system capable of realizing this.

On the other hand, the functional film is a variety of that can be applied to at least one flat panel display selected from LCD (Liquid Crystal Display), PDP (Plasma Display Panel) and OLED (Organic Light Emitting Diodes) in order to transmit and polarize the light in an optimal condition. Kind of optical film (or sheet), such as EMI film, prism film, protective film, diffusion film, reflective film, DBEF, PVA, TAC, OCA (transparent adhesive film for optics), release film, compensation film, reflection It may be a prevention film, a polarizer film, etc., and the panel may include a flat panel display panel selected from LCD (Liquid Crystal Display), PDP (Plasma Display Panel) and OLED (Organic Light Emitting Diodes) panels, and a touch panel. It can be (TSP), Window.

Flexible OLED, which has become a hot topic, attaches various types of functional films, such as polarizing films or OCA (optical transparent adhesive films), between OLED panels and windows. shall.

However, in the conventional functional film attaching system, in order to expand production capacity, a plurality of functional film attaching systems must be installed in parallel, in which case, expensive individual equipment investment and operating personnel are required according to the configuration of the plurality of functional film attaching systems. And, there is a problem that a large area of footprint (Foot Print) is required according to the configuration of a plurality of functional film attachment systems.

For reference, in the present embodiment, the six-axis multi-joint arm 230 is applied, but if it is three or more axes, it can be appropriately modified as necessary.

Meanwhile, the robot peeling head 240 is connected to the distal end of the multi-joint arm 230. The robot peeling head 240, the adhesive rotary roller 241 for film peeling, the roller support body 248, the peeling head body 247, the buffer unit 243, the rolling ball 249 and , A film clamp 242, a clamp actuator 244, and an adsorption unit 246.

The adhesive rolling roller 241 for film peeling is adhered to the surface of the protective film to peel the protective film from at least one of the first panel, the second panel, and the functional film.

The adhesive rotary roller 241 for film peeling is a roller provided on one side of the robot peeling head 240, and serves to peel off a part of the protective film from the panel (or functional film) as shown in FIGS. Since the adhesive material is coated on the surface of the film-releasing adhesive rotary roller 241, the film-adhesive rotary roller 241 contacts the end of the protective film, and when rotated, the protective film as shown in FIGS. 10 to 11 A portion of the film may be peeled off by sticking to the adhesive rotary roller 241 for film peeling while being slightly dried.

The adhesive rotary roller 241 for film peeling includes a rotary roller body 241a and an adhesive coating layer 241b coated on the surface of the rotary roller body 241a. In this embodiment, the adhesive tape is not attached to the adhesive rotary roller, but the adhesive film layer 241b may be provided to remove variation in the thickness and position of the peeling film.

On the other hand, the roller support body 248 rotatably supports the adhesive rotary roller 241 for film peeling. The roller support body 248 is coupled to the peeling head body 247 to be movable relative. With this structure, when the film-type adhesive rotary roller 241 is shaken when contacted with the end of the protective film or excessive force is applied, the force applied to the film-type adhesive rotary roller 241 is buffered while the roller The support body 248 is weak to the peeling head body 247, but can move relative to move upward.

A buffer unit 243 is provided between the roller support body 248 and the peeling head body 247 for buffering the roller support body 248 and the peeling head body 247. The buffer unit 243 provides buffer to a force applied to the adhesive rotary roller 241 for peeling a film to make contact with a constant force. In this embodiment, the buffer unit 243 includes an elastic tension spring 243, one end of which is coupled to the roller support body 248 and the other end of which is coupled to the peeling head body 247, which is usually the thickness of a tremor or a protective film. It can be said that the movement of the adhesive rotary roller 241 for peeling the film due to the deviation is in the order of tens of microns, and there is little change in the force of the elastic tension spring, so it can be said to contact with a constant force.

In more detail, a peeling error may occur when vertical shaking occurs in the multi-joint arm 230 or the like, and the buffer unit 243 cushions the vertical movement by buffering the fine position and pressure changes according to the shaking. The adhesive rolling roller 241 for film peeling is brought into contact with the protective film so as to reduce the peeling error caused by the prior art. In addition, the thickness of the protective film in contact with the adhesive rotary roller 241 for film peeling may be different for each protective film, and even in this case, a peeling error may occur. The buffer unit 243 is a buffer action, so that the peeling error due to the thickness variation or position variation of the protective film is reduced than in the prior art so that the adhesive rotary roller 241 for film peeling contacts the protective film.

And the peeling head body 247 includes a roller lowering limiter stopper portion 247a for limiting the descending of the roller supporting body 248, and one end of the roller lowering limiting stopper portion 243 as described above is a roller supporting body ( 248) and the other end is coupled to the peeling head body 247, whereby the roller lowering stopper portion 243 elastically presses the adhesive rotary roller 241 for film peeling toward the protective film side, but the roller lowering stopper portion The descent is limited to 247a to maintain contact.

In this state, when the adhesive rotary roller 241 for peeling a film contacts the protective film, a force is transmitted to the adhesive rotary roller 241 for peeling a film, and even if excessive force is applied, the roller lowering stopper portion 243 To overcome the elastic force of the roller support body 248 is moved in tens of microns, and then comes into contact with the protective film with a predetermined force,

Meanwhile, a rolling ball 249 is disposed between the roller support body 248 and the peeling head body 247 so that the roller support body 248 becomes rolling friction when the peeling head body 247 is moved relative to the roller support body 248. Accordingly, friction is minimized when the roller supporting body 248 moves relative to the peeling head body 247.

Meanwhile, a film clamp 242 and a clamp actuator 244 are provided in the robot peeling head 240 for interaction with the adhesive rotary roller 241 for peeling a film.

The film clamp 242 is disposed adjacent to the adhesive rotary roller 241 for film peeling in the robot peeling head 240, and serves to clamp the protective film together with the adhesive rotary roller 241 for film peeling.

The film clamp 242 is provided integrally with the film clamp body 242a connected to the clamp actuator 244 and the film clamp body 242a, but the film clamp body 242a is an adhesive rotary roller 241 for peeling a film. It includes a contact clamping portion (242b) for contacting the protective film when approaching) and clamping the protective film together with the adhesive rotary roller (241) for film peeling.

In this embodiment, the contact clamping portion 242b includes a pair of film clamping fingers 242b protruding from the film clamp body toward the adhesive rotary roller 241 for peeling the film, but being spaced apart from each other.

In addition, a curved portion 242c having the same curvature as the outer circumferential curved surface of the adhesive rotary roller 241 for film peeling is formed at an end of the film clamping finger 242b. Therefore, the protective film to be peeled off can be clamped without error between the adhesive rotating roller 241 for peeling the film and the curved portion 242c of the film clamping finger 242b.

The clamp actuator 244 serves to approach or space the film clamp 242 to the adhesive rotary roller 241 for peeling the film. The clamp actuator 244 may be a motor or cylinder structure.

Thus, as shown in FIG. 10 to FIG. 11, after a portion of the protective film is slightly dried and peeled off after being attached to the adhesive rotary roller 241 for peeling the film, the clamp actuator 244 is operated as shown in FIG. 12 to operate the curved portion of the film clamp 242 (242c) is to be pressed against the outer surface of the film-type adhesive rotary roller 241. Then, the partially peeled protective film may be clamped between the curved rotary part 241 for peeling the film and the curved portion 242c of the film clamp 242, and in this state, a multi-joint robotic protective film peeling device as shown in FIG. By operating 200, the protective film can be completely peeled off the panel or functional film.

The robot peeling head 240 is provided with a film detection sensor 245 that detects whether the protective film is clamped to the film clamp 242. After the film detection sensor 245 detects that there is a protective film, the multi-joint robotic protective film peeling device 200 is operated as shown in FIG. 13 to completely peel the protective film from the first panel or the second panel (or functional film). I can do it. Therefore, despite the fact that the protective film is not clamped between the adhesive rotary roller 241 for film peeling and the film clamp 242, it is possible to prevent the occurrence of an error that the multi-joint robotic protective film peeling device 200 operates as shown in FIG. 13. have.

In addition to these components, that is, components for peeling and clamping the protective film, the robot peeling head 240 is further equipped with an adsorption unit 246. The adsorption unit 246 is provided on one side of the robot peeling head 240, and includes a plurality of adsorption pads 246a adsorbing the panel or the functional film by vacuum. The adsorption unit 246 may play a role of adsorbing a panel, a functional film, or other subsidiary materials and moving the position.

On the other hand, the functional film attachment system 10 according to this embodiment further includes an adhesion improving device 300. The adhesion improving device 300 is disposed adjacent to the multi-joint robotic protective film peeling device 200 in FIGS. 1 and 2 along the first panel movement path line 500 and the second panel movement path line 600. , The protective film serves to spray plasma ions toward the peeling surface of the peeled panel.

In other words, the adhesion improving device 300 is disposed on the first panel moving path line 500 and the second panel moving path line 600 in the post-process of the multi-joint robotic protective film peeling device 200, and the protective film Plasma ions are sprayed toward the surface of the peeled panel to improve adhesion to the functional film. Since the plasma ion treatment is performed on the surface to which the functional film is attached, the functional film can be attached better.

In addition, the functional film attachment system 10 according to the present embodiment further includes an alignment camera 400.

Alignment camera 400, as shown in Figures 1 and 2, the first panel and the second panel relative to the functional film alignment (align) or the first panel and the second panel to which the functional film is attached In order to align the relative position of the first panel, the second panel, the functional film and the functional film serves to photograph an alignment image of the attached first panel. In this embodiment, the alignment camera 400 is provided to be fixed in position on the corresponding movement path line.

As shown in detail in FIGS. 14 to 22, the common functional film attachment device 100 is provided on the device body 120 and the device body 120, but the adhesive film 110 is used to attach the functional film to the panel. A functional film attaching part 150 to be attached may be included.

In addition, the common functional film attachment device 100 according to an embodiment of the present invention may further include a sheet mounting unit 130 for mounting the pressure-sensitive adhesive sheet 110 on the device body 120. The first panel slider 191 is provided separately from the device body 120, but may form a place where the functional film is attached to the first panel.

The device body 120 forms the external structure of the common functional film attachment device 100 according to the present embodiment. Structures such as the adhesive sheet 110, the sheet mounting portion 130, and the functional film attaching portion 150 are mounted on the apparatus body 120 by location.

The main body driving unit 121 is provided on one side of the device main body 120. The main body driving unit 121 serves to drive the entire body main body 120 up and down. Since the main body 120 of the device is spaced apart from the top of the panel sliders 191 and 193, the main body driving unit 121 may be provided to control the spacing.

Meanwhile, in the case of the present embodiment, the functional film is not attached to the first panel as it is, but the functional film is attached to the first panel using the adhesive sheet 110. Therefore, prior to the description of the functional film attachment portion 150, the structure and function of the pressure-sensitive adhesive sheet 110 will be described first.

The adhesive sheet 110 applied to this embodiment is a medium used to attach a functional film to the first panel. That is, in the case of this embodiment, rather than attaching the functional film to the first panel as it is, the functional film is first adhered to the adhesive sheet 110 as shown in FIGS. 19 to 22, then the functional film and the first panel are aligned with each other. , By pressing the pressure-sensitive adhesive sheet 110, a functional film can be attached to the first panel.

When a functional film is attached to the first panel via the adhesive sheet 110 as described above, a roll-to-stage method using a conventional set table or a drum-to-stage drum is applied. Unlike the (Drum to Stage) method, it has the advantage of excellent attachment efficiency and quality.

However, when applying the adhesive sheet 110, in the case of simply applying an engineering plastic-based adhesive sheet, an air adsorbing layer (air pocket) sheet, a porous sheet, etc., high elongation due to high elongation ) There is a problem in that it is impossible to cope with the degree of attachment, the life is short, and the down time increases due to a high running cost and frequent replacement cycles.

Thus, this embodiment solves this problem by presenting the adhesive sheet 110 having the following innovative structure. The adhesive sheet 110 applied to the common functional film attaching device 100 according to the present embodiment is disposed between the adhesive layer 111, the reinforcing layer 114, and as shown in FIGS. 17 and 18. A cushion layer 112 and an adhesive layer 113 may be included. 18, the adhesive layer 111, the cushion layer 112, the adhesive layer 113, and the reinforcing layer 114 may be sequentially arranged.

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

For reference, the van der Waals force refers to the force acting between electrically neutral molecules that do not have unpaired electrons. In particular, it refers to a manpower operating at a relatively long distance. The van der Waals force is a result of the dispersing force, and the forces acting between the rare gas atoms and the factors that form molecular crystals of hydrocarbons such as benzene can be explained by the van der Waals force. In addition, the van der Waals force refers to the essential force required to explain the phenomenon of physical adsorption, such as cohesion and adhesion of a liquid, as well as this embodiment.

In summary, the van der Waals force is a very weak electrostatic attraction acting only at very short distances between electrically neutral molecules and collectively refers to the electric forces acting between covalently binding molecules.

Particularly, physical adhesion is possible without additional power through the force of ions. Since the adhesive layer 111 is manufactured based on this van der Waals force, the functional film can be easily adhered and can also be peeled off. have. That is, since a weak viscosity is formed on the adhesive layer 111, it can be adhered to the functional film on the adhesive layer 111, and once the functional film is attached to the panel, the functional film is easily peeled off the adhesive layer 111, that is, detached. Can be.

On the other hand, when applying only the adhesive layer 111 as a sheet in applying the adhesive layer 111, the desired process may be performed well initially, but the adhesive layer 111 may increase due to high adhesion pressure when repeatedly used. However, when the adhesive layer 111 is increased, it is inevitable that a product having a high adhesion degree cannot be supported.

Accordingly, the reinforcing layer 114 is provided on the pressure-sensitive adhesive sheet 110 applied to the common functional film attachment device 100 according to the present embodiment so that this 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 reinforcing layer 114 is applied as a thin stainless steel plate, and is reinforced while supporting the adhesive layer 111 with a larger area than the adhesive layer 111 as shown in FIG. 17. Since the reinforcing layer 114 is applied as a thin stainless steel plate, it is advantageous to match the elongation.

As such, when the reinforcing layer 114 is further applied and applied as the adhesive sheet 110, the elongation can be lowered as close as possible to almost zero, thereby enabling product adhesion with a high degree of adhesion and improving durability. Since it can extend the lifespan, it is possible to not only reduce the running cost, but also the replacement period is long, so that the down time can be significantly 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 cushioning force when a functional film is attached to the panel. Therefore, it is possible to prevent the panel from being damaged while the functional film is attached to the panel while pressing the adhesive sheet 110 with the attachment roller 151 to be described later.

The adhesive layer 113 serves to bond the cushion layer 112 and the reinforcing layer 114. Actually, since the adhesive layer 111 has a weak viscosity and can adhere well to 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 re-applied between the adhesive layer 111 and the cushion layer 112, and it should be said that these matters also fall 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, and a cushion layer 112 and an adhesive layer 113 disposed therebetween, wherein the adhesive layer 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 two or more times greater than the thickness of the reinforcing layer 114. For example, if the thickness of the adhesive layer 111 is 300㎛, the thickness of the reinforcing layer 114 may be 50㎛, the sum of the thickness of the cushion layer 112 and the thickness of the reinforcing layer 114 may be 50㎛. . This is because the portion to which the functional film is substantially adhered is advantageous because the adhesive layer 111 is thick, and the reinforcing layer 114 can be flexible only when it is thin. However, the scope of the present invention is not limited to the numerical values thereof.

As described above, it is preferable to apply the adhesive sheet 110 based on the van der Waals force described above to the common functional film attachment apparatus 100 according to the present embodiment, but this is not necessarily the case. That is, it does not matter even if an adhesive sheet (not shown) coated with a general adhesive material is used. 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 pressure-sensitive adhesive sheet 110 are provided at both ends of the pressure-sensitive adhesive sheet 110 so that the pressure-sensitive adhesive sheet 110 can be mounted at a corresponding position of the device body 120. Combined. In addition, the adhesive sheet 110 may be mounted on the sheet mounting unit 130 through the first and second sheet clamps 116 and 117.

The sheet mounting unit 130 is a configuration provided on one side of the device 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 pressure-sensitive adhesive sheet 110, and the first and second sheet clamps 116 and 117 are attached to the sheet mounting portion 130 in such a manner that the pressure-sensitive adhesive sheet ( 110) may be installed.

The seat mounting unit 130 is provided on one side of the apparatus body 120, and the first clamp mounting support 131 for supporting the first seat clamp 116 is mounted, and the other side of the apparatus body 120 is provided. , A second clamp mounting support 132 for supporting the second seat clamp 117 is mounted.

As described above, the first sheet clamp 116 supporting one end of the adhesive sheet 110 is mounted on the first clamp mounting support 131 and the second sheet clamp 117 supporting the other end of the adhesive sheet 110. The adhesive sheet 110 may be installed in the form of being mounted on the second clamp mounting support 132, the adhesive stretching between the first clamp mounting support 131 and the second clamp mounting support 132. A plurality of seat idle rollers 134 are provided to guide the seat 110.

The plurality of seat 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 this embodiment, the plurality of seat idle rollers 134 are disposed to be rotatable one by one on the side of the first clamp mounting support 131 and the second clamp mounting support 132, all of which are applied as a non-powered free rotating roller. do.

Although the pressure-sensitive adhesive sheet 110 is guided by the action of the sheet idle rollers 134, when the functional film is attached, the pressure-sensitive adhesive sheet 110 is pressed toward the panel. There is a fear that the initial tension may be distorted. Thus, the sheet tension holding unit 140 is provided.

The sheet tension holding unit 140 is provided on at least one of the first clamp mounting support 131 and the second clamp mounting support 132, and serves to maintain the tension of the adhesive sheet 110. In the case of this embodiment, the seat tension holding unit 140 is provided on the side of the first clamp mounting support 131. However, this is only one example. That is, the seat tension holding unit 140 may be provided on the side of the second clamp mounting support 132 or may be provided on both the first clamp mounting support 131 and the second clamp mounting support 132. There will be.

The seat tension holding unit 140 includes a sliding rail 141 coupled to one side of the device body 120 and a rail block 143 engaged with the rail on the sliding rail 141, and the first clamp mounting support ( It may include a support support 142 coupled to 131), and a tension cylinder 144 connected to the support support 142 and operated. Accordingly, since the tension cylinder 144 presses or pulls the support support 142 at a predetermined pressing force, the tension of the initially set value can be maintained as it is.

On the other hand, the common functional film attachment device 100 according to this embodiment is equipped with a functional film attachment portion 150 as described above. The functional film attachment portion 150 is provided on the apparatus body 120 to be adjacent to the sheet mounting portion 130, and after the functional film is adhered to the adhesive sheet 110 in an unfolded state, the adhesive sheet 110 is used. It serves to attach a functional film to the first panel.

In other words, the functional film attachment unit 150 first adheres the functional film to the adhesive sheet 110 as shown in FIGS. 19 to 22, and then aligns the relative position of the first panel with respect to the functional film based on the functional film. Next, by pressing the pressure-sensitive adhesive sheet 110 so that the functional film can be attached to the first panel. After the functional film is attached to the first panel, the pressure-sensitive adhesive sheet 110 is peeled from the functional film, that is, detached.

The functional film attachment part 150 that plays such a role includes an attachment roller 151, a backup roller 152 and a sheet release roller 153 connected to one body by the roller support module 155, and a roller support module ( A module up / down driving unit 160 driving up / down 155 and a module driving unit 170 driving the roller support module 155 may be included.

The attachment roller 151 is such that the functional film adheres to the adhesive layer 111 of the adhesive sheet 110 as shown in FIGS. 19 to 20 or the adhesive sheet 110 so that the functional film is attached to the first panel as shown in FIG. It is a roller that is pressed and moved on the bed.

In other words, the attachment roller 151 is rotated in the reinforcing layer 114 on the adhesive sheet 110 while pressing the adhesive sheet 110 from one side to the other. Accordingly, a process in which the functional film is adhered to the adhesive layer 111 of the adhesive sheet 110 as in FIG. 19 to FIG. 20 may be performed, and a process in which the functional film is attached to the panel as in FIG. 21 in FIG. 21 may be performed.

The backup roller 152 is external to the attachment roller 151 and is a roller that supports rotation of the attachment roller 151. The backup roller 152 may have a larger diameter than the attachment roller 151. Due to the action of the backup roller 152, the attachment roller 151 has an adhesive layer (110) of the adhesive sheet 110 as shown in FIGS. 111) to ensure that the functional film is adhered to or the functional film is attached to the panel as shown in FIGS. 21 to 22, so that the process can proceed well.

The sheet release roller 153 is a roller having a function of allowing the adhesive sheet 110 to be detached from the functional film when the functional film is attached to the panel as shown in FIG. 22. The sheet release roller 153 is disposed under the adhesive sheet 110 at a higher position than the attachment roller 151. Since the sheet release roller 153 is disposed under the adhesive sheet 110 as described above, when the sheet release roller 153 is up, the adhesive sheet 110 may peel off from the functional film, that is, detached.

The attachment roller 151, the backup roller 152 and the seat release roller 153 described above are supported by one body by the roller support module 155. Therefore, when the roller support module 155 is up, the attachment roller 151, the backup roller 152, and the seat release roller 153 may also be up together, and the roller support module 155 may be down ( down), the attachment roller 151, the backup roller 152, and the sheet release roller 153 may also be down together.

The module up / down driving unit 160 is provided on the device body 120 and serves to drive the roller support module 155 up / down. In this embodiment, the module up / down driving unit 160 includes a low friction cylinder 161. In addition, the low friction cylinder 161 is provided with a load cell 162 that senses the pressing force at which the attachment roller 151 is pressed against the adhesive sheet 110. The controller (not shown) can press the pressure sensitive adhesive sheet 110 at a constant pressure by controlling the force of the low friction cylinder 161 by the information of the load cell 162, and thereby the functional film on the pressure sensitive adhesive sheet 110 The adhesive may be allowed to adhere or a functional film may be attached to the first panel.

The module running unit 170 is provided on the device body 120, but is connected to the roller support module 155 and the module up / down driving unit 160, and the roller support module 155, as shown in FIGS. 20 and 22, is a panel slider ( 191, 193).

Accordingly, when the motor 171 is driven and the ball screw 172 is rotated, the roller support module 155, including the module up / down driving unit 160 due to the action of the screw nut 173 moved on the ball screw 172, The whole can be driven reciprocally on the panel sliders 191 and 193. The controller (not shown) controls the operation of the module up / down driving unit 160 and the module driving unit 170 based on process conditions such that the functional film adheres to the adhesive sheet 110 or the functional film adheres to the panel. I can control it.

Hereinafter, the operation of the functional film attachment system 10 according to this embodiment will be described.

The functional film loaded on the film slider 195 is moved in the order of ⑤ and ④ from the loading position of FIG. 2 along the first film movement path line 710, and finally to the common functional film attachment device 100 of ④. Is supplied. At this time, the functional film reaches position ⑤, and an edge is photographed by the alignment camera 400. The captured image information is transmitted to a controller (not shown). Then, after reaching position ④ and being supplied to the common functional film attachment device 100, it is first adhered to the adhesive sheet 110 as shown in FIG.

Let's look at this. That is, when the functional film is loaded on the panel sliders 191 and 193 as shown in FIG. 18, the roller support module 155 is down by the module up / down driving unit 160. Subsequently, as shown in FIG. 21, the functional film is applied to the adhesive layer 111 of the adhesive sheet 110 through the adhesive force based on the van der Waals force by moving the roller support module 155 from one side to the other side by the action of the module running unit 170. Sticks. After the functional film is adhered to the adhesive sheet 110, the roller support module 155 is up by the module up / down driving unit 160.

Thereafter, the protective film adhered to the surface is peeled off by the multi-joint robotic protective film peeling device 200. The functional film with the protective film peeled off waits in a state adhered to the adhesive sheet 110 in the common functional film attachment device 100 of ④.

In this way, the first film is moved in the order of ① to ③ in FIG. 2 in the process of waiting for the protective film to be peeled off and waiting for the functional film to adhere to the adhesive sheet 110. It is supplied to the attachment device 100.

The first panel reaches the position ① and the protective film adhered to the surface is peeled off in the process of FIGS. 10 to 13 by the multi-joint robotic protective film peeling device 200, and reaches the position ② to improve the adhesion After the plasma ion treatment is performed by 300, the position ③ is reached, and an alignment mark is photographed by the alignment camera 400. The captured image information is also transmitted to a controller (not shown).

And it is supplied to the common functional film attachment device 100 of ④. At this time, since the functional film is already adhered to the adhesive sheet 110 of the common functional film attachment device 100, the alignment operation with respect to the first panel to align the relative position of the first panel based on the functional film This progresses. As described above, alignment of the first panel may be performed while the first panel is moved to the common functional film attachment device 100.

When the aligned first panel reaches the attachment position, the roller support module 155 is again down by the module up / down driving unit 160. Subsequently, the roller support module 155 is further down by the module up / down driving unit 160 as shown in FIG. 21 so that the functional film contacts the first panel by the action of the attachment roller 151.

Then, as shown in FIG. 22, the roller support module 155 is moved from the other side to one side by the action of the module driving unit 170, so that the attachment roller 151 is functional to the first panel due to the force pressing the adhesive sheet 110. Allow the film to adhere. After the functional film is attached to the first panel, the roller support module 155 is again up by the module up / down driving unit 160, and the adhesive sheet is released from the functional film due to its action. Thus, the first film attaching operation is completed.

Next, the functional film is moved along the second film movement path line 720 in the loading place and finally supplied to the common functional film attachment device 100 at the position ④.
