Description

Glass remover for flat panel display {Glass remover}

The present invention relates to a glass removing apparatus for a flat panel display, and more particularly, from a glass removing work line for producing a glass bonding film in which glass is bonded to a film as a glass removing film from which glass is removed, for example, a laminating process or the like. The present invention relates to a glass removing device for a flat panel display which can be easily and efficiently transported without damaging the glass removing film in a post process.

A flat panel display (FPD) is an image display device that is thinner and lighter than a cathode ray tube (CRT), which has previously been mainly used as a display for a TV or a computer monitor.

Planar displays include liquid crystal displays (LCDs), plasma display panels (PDPs), organic light emitting diodes (OLEDs), and the like.

On the other hand, Figures 1a and 1b is an operation diagram for the film removing apparatus of a common glass substrate, respectively.

The film removing apparatus of the glass substrate shown in these figures is a device which removes the protective film which protects the surface of a glass substrate from a glass substrate using the rotating vacuum roll 10. As shown in FIG. At this time, the glass substrate may be a substrate for LCD or PDP.

That is, after the rotary vacuum roll 10 is vacuum-adsorbed to the protective film as shown in Figure 1a, the rotary vacuum roll 10 as shown in Figure 1b is rotated in the direction of the arrow A and the glass substrate proceeds in the direction of the arrow B as shown in the glass substrate The protective film adhered to can be removed.

In this case, since the protective film removed from the glass substrate is not a problem even if damaged, the rotary vacuum roll 10 can be used, and also the protective film can be quickly removed.

However, unlike the LCD or PDP substrates applied to FIGS. 1A and 1B, in the case of the OLED substrate applied to the OLED flexible cell logistics, the film EL is used and the glass is removed. The film must not be damaged when the glass is removed.

However, when the vacuum roll 10 shown in FIGS. 1A and 1B is used to use the film while removing the glass from the OLED substrate, the film from which the glass is removed is removed along the surface of the vacuum roll 10. Since it is bent while exiting, the film may be damaged.

In order to prevent the film from being damaged, a large vacuum roll (not shown) should be used. In this case, a problem occurs that marks remain on the film due to the vacuum hole formed in the vacuum roll.

Therefore, when the film is to be used while removing the glass from the OLED substrate, it is difficult to apply the apparatus of FIGS. 1A and 1B described above.

As an alternative to this, a technique of removing the glass by adsorbing the glass under vacuum, lifting and releasing the edge of the glass, and then lifting and releasing the center may be considered. When applied, it is difficult to apply because static electricity is generated between the glass and the PI layer of the flexible cell, and there is still a possibility of damaging the film. Therefore, a new alternative was required. It is currently under review.

On the other hand, after the glass is separated from the film, the glass should be transported to the glass stack but the film must be transferred to a later process, for example, a laminating process of laminating another kind of film on the upper surface of the glass (glass removing film). .

At this time, if a series of processes for transferring the glass removing film from which glass is removed after the glass is removed to the post process is not performed in-line, the glass removing film may be transferred to the post process at an initial position. The glass removal film should be returned to the in loading unit. That is, the glass removing film should be transferred to the loading unit while being transported backward so that the glass removing film is returned to the loading unit which is the initial position of the process. In this case, the loading unit performs the role of unloading, and the glass removing film may be transferred to a post process, for example, a laminating process after reaching the loading unit performing the unloading role.

However, at the time of loading, the glass is attached to the film, that is, the state of the glass bonding film, so the transfer adsorbs the upper surface of the glass to remove the glass from the loading unit. However, since the upper surface of the glass removing film cannot be adsorbed after the glass is removed, it is difficult to transfer the glass removing film toward the loading unit, so it is difficult to easily transfer the glass removing film to a post process such as a laminating process. .

Similarly, even if a series of processes for transferring the glass removing film from which glass is removed to the post process after removing the glass is in-line, from the glass removing work line to a post process such as a laminating process. In order to easily and efficiently transport the glass removing film without damage, there is a need for a glass removing apparatus having a new unloading unit having an efficient structure.

none

2 and 3, the glass removing apparatus for a flat panel display of the present embodiment includes a glass-bonded film in which glass is bonded to one surface of a film EL used in an OLED manufacturing process. 8 is disposed adjacent to the glass removing operation unit 100 and the glass removing operation unit 100 to form a glass removing operation line, which is a working line made of the glass removing film (see FIG. 10) from which the glass is removed from the glass removing film (see FIG. 10). And an in-line with the glass removing operation unit 100, and includes an unloading unit 170 for unloading the glass removing film in a post-process by holding the glass removing film in a floating state. do.

2 and 3, the glass removing apparatus for a flat panel display of the present embodiment is disposed on the opposite side of the unloading unit 170 with the glass removing operation unit 100 interposed therebetween to glass the glass-bonded film. It includes a loading unit 101 for loading into the removal unit 100.

As described above, the glass removing apparatus for the flat panel display of the present embodiment has a structure having all of the loading unit 101, the glass removing operation unit 100, and the unloading unit 170, as shown in FIGS. 2 and 3. At this time, the loading unit 101, the glass removing operation unit 100, and the unloading unit 170 form an in-line working line. Therefore, when the glass bonding film is loaded into the loading unit 101, the glass bonding film is transferred to the glass removing work unit 100 along the direction of the arrow of FIG. 2 to be produced as a glass removing film, and then continuously transferred to the unloading unit. Via 170 is directed to a post process, such as a laminating process.

As such, when the loading unit 101, the glass removing operation unit 100, and the unloading unit 170 form an in-line working line, in particular, the glass removing film can be easily and efficiently post-processed without damage. Can be transferred to. In addition, the process efficiency can be remarkably improved compared to the prior art, which is difficult to transfer the glass removing film to the post-process as it is difficult to hold the glass removing film as in the prior art can be expected to improve productivity.

First, with reference to the loading unit 101, the loading unit 101 is shown on the left side in Figs. As described above, the loading unit 101 loads the glass bonding film and serves to transfer the glass bonding film to the glass removing operation unit 100.

In the present embodiment, the loading unit 101 is manufactured in substantially the same manner as the unloading unit 170 which will be described later in detail in order to simplify the equipment. Therefore, since the detailed structure of the loading unit 101 can be easily known from the structure of the unloading unit 170, description of the loading unit 101 is omitted.

Next, the glass removing operation unit 100 forms a glass removing operation line, which is a working line for manufacturing a glass bonding film (see FIG. 8) into a glass removing film (see FIG. 10).

The glass removing operation unit 100, as shown in Figure 3 to 10, the glass holding module 105 for holding the glass to be removed from the film with respect to the glass-bonded film, and a predetermined angle of the film with respect to the glass It includes an inclination separation module 130 for inclined transfer.

The glass gripping module 105 grips the glass constituting the upper layer on the work line to which the glass and the film are bonded to each other. The glass gripping module 105 grips the glass by a vacuum suction method. The glass gripping module 105 includes a glass gripping member 110 that absorbs and grips glass, and transfers 121, 122, and 123 that are connected to the glass gripping member 110 and move the glass gripping member 110.

The glass gripping member 110 is capable of gripping the glass by vacuum, as shown in the enlarged view of FIG. 5, the body 111 and a plurality of nozzle brackets 112 connected to the body 111. ) And a plurality of adsorption nozzles 113 respectively coupled to the plurality of nozzle brackets 112 and adsorbing the glass by vacuum pressure.

The plurality of nozzle brackets 112 may be arranged in a plurality at regular intervals below the body portion 111. The plurality of nozzle brackets 112 is a portion supporting the plurality of suction nozzles 113.

The plurality of adsorption nozzles 113 is a portion that substantially adsorbs the glass in a vacuum. Two nozzle brackets 112 may be provided. This is a means to hold the glass more stably, unlike the drawing may be arranged one suction nozzle 113 in one nozzle bracket 112.

On the other hand, when the glass is held in a vacuum by the glass holding member 110, due to the LTPS, EL, thin-film encapsulation forming the OLED may be raised when the edge region of the film moves on the conveyor. In this case, the glass holding member 110 may not hold the glass well. In order to prevent such a phenomenon, a pressing part (not shown) for pressing the front part of the film may be further provided at the front part of the glass gripping module 105. That is, the glass holding module 105 may reduce the adsorption failure by allowing the pressing unit to pressurize the film so that the front portion of the film is well adsorbed on the surface of the inclined separation module 130.

The transfers 121, 122, and 123 serve to move the glass gripping member 110 holding the glass. The transfer (121, 122, 123), the Z-axis transfer 121 and the glass holding member 110 for moving the glass holding member 110 to the Z axis (see Fig. 4) in the vertical direction with respect to the inclined separation module 130. The glass gripping is performed by the X-axis transfer 122 that moves in the X-axis (see FIG. 3), which is the feed direction of the inclination separation module 130, and the Y-axis (see FIG. 3), which is the direction crossing the X-axis transfer 122. And Y-axis transfer 123 to move the member. The transfers 121, 122, and 123 may be implemented as cylinders or linear motors.

The inclination separation module 130 serves to transfer the film to the glass inclined at a predetermined angle. In other words, as shown in FIGS. 8 to 10, the glass holding module 105 adsorbs and moves the glass so that the inclined separation module 130 moves the film in the inclined direction by adsorbing the glass to naturally move the glass from the film. It can be removed and produced into a glass removing film.

However, in this case, if either one of the glass holding module 105 and the inclined separation module 130 is too fast or too late than the other, the removal of the glass is difficult to proceed properly, the glass holding module 105 and the slope Separation module 130 will have to be synchronized with each other by a control unit (not shown). This may be implemented in such a manner that the control unit adjusts the moving speed of the inclination separation module 130 to the transfers 121, 122, and 123, or conversely, adjusts the moving speed of the transfer 121, 122, 123 to the inclination separation module 130.

In this embodiment, but not necessarily, the inclination separation module 130 may be applied to the glass separation inclination conveyor 130. That is, the inclination separation module 130 is applied as a conveyor in which a vacuum is formed. Of course, it is not necessary to limit the scope of the present invention to these matters.

4 and 8 to 10, the glass separation POSOS conveyor 130, the glass holding module 105 is operated to hold the glass, but the straight section portion that the glass and film are moved together in a straight line ( 130 and an inclined section 130b provided to be inclined by a predetermined angle with respect to the straight section 130 and to which the film from which the glass is removed is moved alone.

In this embodiment, the straight section 130 and the inclined section 130b is provided integrally. In other words, when fabricating the glass separating inclined conveyor 130, the inclined section 130b is formed on the rear end side.

As such, the straight section 130 and the inclined section 130b are provided on the glass separating inclined conveyor 130, and the inclined section is formed when the glass is held by the glass gripping module 105 at the straight section 130. On the 130b side, only the film from which the glass has been removed can be transferred. Therefore, the glass can be easily and easily removed from the film even without applying the conventional structures as shown in FIGS. 1A and 1B, and in particular, since the film does not dry after the glass is removed, the film may be damaged. .

However, since the scope of the present invention is not limited thereto, the straight section 130 and the inclined section 130b may have a separate structure. In this case, a hinge structure may be applied between the straight section 130 and the inclined section 130b so that they can be relatively rotated with each other. In particular, when the straight section 130 and the inclined section 130b has a separate structure, the inclination of the inclined section 130b may be adjusted by connecting an actuator to the inclined section 130b.

Since the glass separation inclination conveyor 130 has to transfer the film while adsorbing the film by vacuum, the vacuum structure is applied to the glass separation inclination conveyor 130. This will be described in detail with reference to FIGS. 6 and 7. 6 and 7 show the structure of one unit of the glass inclined conveyor 130 for separating.

Porous inclined conveyor 130 for glass separation has a plurality of vacuum holes 141 is formed on the surface, the porous conveying belt 140 is seated and supported by the vacuum pressure formed in the vacuum hole 141 and transported; The vacuum chamber 150 is formed below the porous transfer belt 140.

While the vacuum chamber 150 is a portion fixed to the lower region of the apparatus, the porous transfer belt 140 serves to transfer the film by being in direct contact with the film. The porous transfer belt 140 may be coupled relative to the vacuum chamber 105 in the upper portion of the vacuum chamber 105 along the transfer direction of the film so as to be relatively movable.

The porous transfer belt 140 may have a closed loop shape like a conventional conveyor belt. As the porous transfer belt 140 is rotated, the pores inclined conveyor 130 for separating the glass may be provided with a motor (not shown) to force the film to be forcibly transferred.

On the upper surface of the vacuum chamber 150 is formed a vacuum slot 152 in communication with a plurality of vacuum holes 141 formed in the porous transfer belt 140. The vacuum slot 152 is formed in the stepped portion 154 stepped downward from the upper surface of the vacuum chamber 150. An air circulation passage 153 is formed on the bottom surface of the vacuum chamber 150 facing the vacuum slot 152.

The air flow space 151 in the vacuum chamber 150 may be divided into a plurality of zones Z1, Z2, Z3, and zones in which vacuums are formed separately from each other, and the vacuum slot 152 may be divided into each zone Z1. It may be provided on the upper surface of the vacuum chamber 150 so as to correspond to each of the, Z2, Z3 ,,,). As such, the air flow space 151 in the vacuum chamber 150 is formed of a plurality of zones Z1, Z2, Z3 in which vacuums are formed separately from each other, and correspond to each zone Z1, Z2, Z3,. When the vacuum slot 152 is formed in a divided manner, even if a leak of vacuum is generated in one of the zones Z1, Z2, Z3, ..., the other zones Z1, Z2, Z3, ... Since the vacuum can be provided, vacuum adsorption between the porous transfer belt 140 and the film is released, thereby preventing the transfer of the film to failure.

However, since the scope of the present invention does not need to be limited thereto, unlike the drawing, the vacuum slot 152 may be continuously formed on the upper surface of the vacuum chamber 150 along the longitudinal direction of the porous transfer belt 140. In addition, the air flow space 151 in the vacuum chamber 150 does not necessarily need to be formed of a plurality of zones Z1, Z2, and Z3 in which vacuum is individually formed.

Thus, when the vacuum pump (not shown) is operated, as shown by the arrow in FIG. 7, the vacuum pump 141 and the vacuum slot 152 in the vacuum chamber 150 are located outside the vacuum hole 141. As the vacuum is formed toward the air flow space 151 and the air circulation passage 153, the film may be adsorbed by the vacuum on the surface of the porous transfer belt 140. In fact, the experiments, even if the length of the film in the width / length of about 1.5 meters (m), the vacuum adsorption force by the porous transfer belt 140 has been confirmed that there is no difficulty in transferring the film at high speed.

Referring to FIG. 5, the flat panel display glass removing device of the present embodiment is provided with an ionizer 160 disposed adjacent to the inclined separation module 130 to inject an antistatic fluid into the glass. The ionizer 160 prevents static electricity from being generated between the glass and the PI layer of the flexible cell by spraying an antistatic fluid toward the film and the glass during the operation of removing the glass from the film. The ionizer 160 may be disposed on both sides of the inclined separation module 130 as shown in FIG. 3 to inject antistatic fluid into both sides of the glass.

Meanwhile, as shown in FIGS. 2, 3, and 11 to 13, the unloading unit 170 forms an in-line with the glass removing operation unit 100, and floats the glass removing film. In this state, the glass removing film is gripped to serve as a post process, for example, a laminating process. As described above, since the loading unit 101 has substantially the same structure as the unloading unit 170, the detailed structure of the loading unit 101 refers to the detailed structure of the unloading unit 170.

As shown in detail in FIGS. 11 to 13, the unloading unit 170 floats the glass removing film transferred along the glass removing operation unit 100 by a predetermined height to prevent deflection of the glass removing film. Adjacent to the floating module 180 and the film floating module 180, the film adsorption for adsorbing one area of the glass removal film that is floated by a predetermined height by the film floating module 180 to transfer to the post-process A transfer module 190.

In this case, a support peak plate 173 may be provided between the glass removing operation unit 100 and the unloading unit 170 to prevent sagging of the glass removing film. The support peak plate 173 of the porous structure prevents the sagging of the glass removing film passing between the glass removing unit 100 and the unloading unit 170 through upward spraying of compressed air.

In this embodiment, the film floating module 180 is applied as a plurality of film floating unit modules 181 spaced apart from each other and arranged side by side. Although three film floating unit modules 181 are shown in the drawings, the scope of the present invention is not limited thereto.

Referring to Figure 17 looks at the film floating unit module 181. The film floating unit module 181 is coupled to the upper body 181a and the upper body 181a, and the upper body 181a is formed with a plurality of air injection holes 181d into which compressed air is injected to one surface facing the glass removing film. A lower body 181b defining an airflow space 181e between the air flow space 181a and a blowing fan 181c disposed in the airflow space 181e to generate compressed air toward the air injection holes 181d. do.

The upper body 181a forms a tubular structure with its lower surface opened. That is, the inside is formed of an almost rectangular parallelepiped shape, with a part of which is open. The air injection holes 181d formed on the upper surface of the upper body 181a may be processed by a punching method, but the upper body 181a may be made of an aero fix material in which the air injection holes 181d are formed. A filter 181f may be provided in the upper body 181a and in the air flow space 181e to filter foreign matter in the compressed air generated by the blowing fan 181c. Any filter such as a hepa filter or a prefilter may be applied to the filter 181f.

The lower body 181b has a shape substantially similar to that of the upper body 181a, but is formed in a somewhat small volume. That is, the lower body 181b may consider the state which turned the upper body 181a upside down substantially. The lower body 181b is combined with the upper body 181a to form an air flow space 181e therein.

The blowing fan 181c is disposed in the air flow space 181e to generate compressed air toward the air injection holes 181d. Since the film floating unit module 181 is formed to have a sufficiently long length, a plurality of blower fans 181c provided in the lower body 181b may be disposed at appropriate intervals. In the drawing, the blower fan 181c is illustrated in the shape of a fan blade to highlight the blower fan 181c. However, the blower fan 181c may have a cross flow fan in addition to the axial fan shown.

The film adsorption transfer module 190 is disposed adjacent to the film floating module 180 and adsorbs a region of the glass removing film floating by a predetermined height by the film floating module 180 to post-process, for example, laminating. It serves to transfer to the process.

As shown in FIG. 12, the film adsorption transport module 190 may be provided in pairs in parallel with the film floating unit modules 181 on both sides of the film floating unit modules 181. Therefore, the glass removing film wound up to a certain height by the film floating unit modules 181 may be transferred to a later process after both sides of the lower end thereof are adsorbed by a pair of film adsorption transfer modules 190.

The film adsorption transfer module 190 includes a porous belt 191 for adsorbing a glass removing film, a driving sprocket 192 and a driven sprocket 193 in which the porous belt 191 is wound in a closed loop shape, and And a feeding motor 194 connected to the driving sprocket 192 side.

Thus, when the feeding motor 194 is driven, the porous sprocket 191 wound around the driving sprocket 192 and the driven sprocket 193 may be moved in one direction, thereby transferring the glass removing film. For reference, the porous belt 191 is a kind of adsorptive pad having a porous hole, and may adsorb the glass removing film when contacted with the glass removing film.
