Description

Stripping device

Technical Field

The present invention relates to a peeling apparatus.

Background

In general, a display device includes a display panel and a polarizing film (polarizing plate) attached to one or both surfaces of the display panel by an adhesive.

Such a display device is manufactured by bonding a polarizing film to a display panel, and is inspected after the manufacture. In the process of inspection, when a defect due to misalignment or inflow of foreign matter or the like is detected, the polarizing film is peeled off from the display panel, and thereafter a new polarizing film is reattached to the display panel.

Recently, since the display device becomes large in size and thin in thickness, the rigidity of the display panel becomes weak, and the display panel may be easily broken even by a small external force. Therefore, the polarizing film may be broken during the peeling of the polarizing film, or the display panel may be deformed or broken due to an external force applied to the display panel in order to separate the polarizing film from the display panel.

Fig. 1 is a plan view showing a peeling apparatus according to an embodiment of the present invention, fig. 2 is a side view showing the peeling apparatus according to the first embodiment of the present invention, and a state in which a part of a polarizing film 62 of a display device 60 is peeled from a display panel 61 is illustrated in fig. 1.

Referring to fig. 2, the peeling apparatus 1 according to an embodiment of the present invention includes a first table 11, a second table 12, a peeling roller 20, a plurality of upper supporting rollers 30, and a plurality of lower supporting rollers 40.

A display device 60 having a polarizing film 62 attached to one surface of a display panel 61 is mounted on the first stage 11. A corner portion of the polarizing film 62 may be first separated from the display panel 61 by an operator and then attached to the peeling roller 20 by bonding or the like. If the peeling roller 20 is rotated by means of the control device 50 such as a driving motor, the polarizing film 62 connected to the peeling roller 20 is wound around the peeling roller 20 and peeled from the display panel 61. While the polarizing film 62 is peeled off, the display panel 61 is moved in the direction X perpendicular to the peeling portion P. The display panel 61 from which the polarizing film 62 is removed by the peeling roller 20 is loaded to the second table 12 spaced apart from the first table 11 by a preset interval.

In the first embodiment of the present invention, the peeling roller 20 is disposed on the upper portion of the first table 11, but in other embodiments of the present invention, the peeling roller 20 may be disposed on the lower portion of the first table 11.

In various embodiments of the present invention, the first table 11 and the second table 12 may be configured as air floating tables. Specifically, the first table 11 and the second table 12 may be made of a porous material made of any one of stainless steel (stainless steel), aluminum alloy, brass, hastelloy (hastelloy) alloy, and zirconium, and air may be dispersed from the outside toward the upper portions of the first table 11 and the second table 12. The display panel 61 mounted on the upper portions of the first table 11 and the second table 12 can be floated by the gap of the porous material. The floating display panel 61 can be freely moved (slid) and rotated by a corresponding external force while the polarizing film 62 is peeled. In one example, the floating display panel 61 may be freely moved in the moving direction X while the polarizing film 62 is peeled off.

Since the display panel 61 is floated from the surfaces of the first table 11 and the second table 12, it is possible to prevent scratches or electrification (electric charge) due to direct contact with the surfaces of the first table 11 and the second table 12 when moving in the moving direction X.

The plurality of upper supporting

rollers

31, 32 may include: a first upper support roller 31 disposed adjacent to the first table 11; and a second upper support roller 32 disposed adjacent to the second table 12. The

upper support rollers

31, 32 may be disposed adjacent to the peeling portion P of the polarizing film 62. During the period in which the polarizing film 62 is peeled, the upper supporting

rollers

31, 32 may be rotated in a direction that facilitates movement of the display device 60.

While the polarizing film 62 is peeled off, a tension in the upper direction is applied to the display panel 61 due to the adhesive force between the polarizing film 62 and the display panel 61, and the display panel 61 may float at the peeling portion P. Such tension may cause the display panel 61 to be deformed or damaged. The

upper support rollers

31 and 32 can press the display device 60 to the lower portions of the first table 11 and the second table 12 while the polarizing film 62 is peeled, thereby preventing the display panel 61 from floating. Further, since the

upper support rollers

31 and 32 press and support the display device 60, the polarizing film 62 can be more easily separated from the display panel 61.

More specifically, the first upper supporting roller 31 is disposed adjacent to the peeling section P on the first table 11, and further presses and supports the display device 60 before the polarizing film 62 is peeled. The polarizing film 62 that has just been peeled off is wound around the peeling roller 20 via the outer periphery of the first upper supporting roller 31.

In various embodiments of the present invention, the first upper supporting roller 31 may be disposed between the peeling roller 20 and the second upper supporting roller 32. In such an embodiment, the peeling angle between the polarizing film 62 that has just been peeled and the polarizing film that has not been peeled may be determined according to the relative position of the first upper supporting roller 31 and the peeling roller 20. The peeling roller 20 is configured to be movable forward and backward with respect to the moving direction X of the display panel 61, and can control the peeling angle. In various embodiments of the present invention, the peel angle may vary from 50 to 170 °.

The magnitude of the vertical direction and horizontal direction components of the tension applied to the polarizing film 62 for peeling can be controlled according to the peeling angle. In the present invention, by adaptively controlling the peeling angle according to the area, thickness, adhesive force, and the like of the polarizing film 62, tension having an appropriate magnitude and direction can be applied to the polarizing film 62, and as a result, breakage of the polarizing film 62 during peeling can be prevented. In addition, the present invention can prevent the shape of the display panel 61 from being deformed or the display panel 61 from being damaged due to an excessive vertical tension applied to the display panel 61 by adaptively controlling the peeling angle.

The second upper supporting roller 32 is disposed adjacent to the peeling part P on the second table 12, and further pressurizes and supports the display panel 61 after the polarizing film 62 is peeled. In various embodiments of the present invention, the second upper supporting roller 32 may be configured to be movable in a direction toward the first upper supporting roller 31 and in a direction away from the first upper supporting roller 31. The distance between the first upper supporting roller 31 and the second upper supporting roller 32 may be controlled according to the movement of the second upper supporting roller 32.

In various embodiments of the present invention, the distance D between the centers of the first and second upper supporting

rollers

31 and 32 may be determined according to the diameters of the first and second upper supporting

rollers

31 and 32 and the distance between the first and second upper supporting

rollers

31 and 32 controlled by the movement of the second upper supporting roller 32. Referring to fig. 2, the smaller the distance D between the centers of the first and second upper supporting

rollers

31 and 32, the smaller the area of the display panel 61 floated by the tension may be. However, if the diameter of the upper support roller 30 is reduced in order to reduce the distance D between the centers of the first and second

upper support rollers

31 and 32, the outer circumference of the first upper support roller 31 becomes sharp, so that the polarizing film 62 may be broken. Therefore, the diameter of the upper supporting roller 30 and the distance D between the centers of the upper supporting rollers 30 should be selected appropriately. In various embodiments of the present invention, when the diameters of the first and second upper supporting

rollers

31 and 32 are about 28mm, the distance D between the centers of the first and second upper supporting

rollers

31 and 32 may be set to 28mm or less. Accordingly, the polarizing film 62 can be prevented from being easily broken when peeled off, and the area of the display device 60 floating at the peeling portion P can be minimized.

In various embodiments of the present invention, the peeling apparatus 1 may further include a plurality of lower supporting rollers 40. A plurality of lower support rollers 40 may be disposed in a space that separates the first table 11 from the second table 12. The plurality of lower supporting rollers 41, 42 may include: a first lower support roller 41 disposed below the first upper support roller 31; and a second lower supporting roller 42 disposed below the second upper supporting roller 32. The lower support rollers 41, 42 may be disposed adjacent to the peeling portion P of the polarizing film 62. During the period in which the polarizing film 62 is peeled, the lower supporting rollers 41, 42 may be rotated in a direction that facilitates the movement of the display device 60.

While the polarizing film 62 is peeled off, a tension in the upper direction is applied to the display panel 61 due to the adhesive force between the polarizing film 62 and the display panel 61, and the display panel 61 may float at the peeling portion P. Such floating of the display panel 61 may cause deformation of the display panel, for example, separation between stacked bodies constituting the display panel 61. The lower supporting rollers 41, 42 may support the lower portion of the floated display panel 61 during the polarizing film 62 is peeled off, thereby preventing deformation of the display panel 61 such as separation between stacked bodies of the display panel 61.

The lower support rollers 41 and 42 are disposed to be vertically movable, and configured to be capable of supporting the display panel 61 from below to an extent that the display panel 61 floats. To this end, the lower support rollers 41, 42 may include actuators or springs controlled by the control device. The display device 60 is supported up and down by the

upper support rollers

31, 32 and the lower support rollers 41, 42, thereby preventing the polarizing film 62 from being deformed or damaged during being peeled off and making the polarizing film 62 easy to peel off.

Referring again to fig. 2, in various embodiments of the present invention, the peeling apparatus 1 may further include a plurality of

support rollers

70, 80. The plurality of

support rollers

70, 80 may include: a first support roller 70 disposed on the first table 11; and a second support roller 80 disposed on the second table 12.

The first support roller 70 may include at least one

roller

71, 72, 73. The first support roller 70 supports the display device 60 moving on the first table 11 together with the first upper support roller 31, thereby preventing the display device 60 from being pulled by tension and preventing the display panel 61 from being deformed. In order to apply appropriate pressure to the moving display device 60, the first supporting roller 70 may include a buffer (damper) and a spring, etc. Also, in various embodiments of the present invention, the first supporting roller 70 may be integrally formed with the first upper supporting roller 31 on one body.

The second supporting roller 80 may support the display device 60 moving on the second table 12 together with the second upper supporting roller 32. In various embodiments of the present invention, the second supporting roller 800 may be integrally formed with the second upper supporting roller 32 on one body. In this case, the body may control the movement of the second upper supporting roller 32, and the second supporting roller 80 may be moved together with the second upper supporting roller 32 by the movement of the body.

In various embodiments of the present invention, the peeling apparatus 1 may further include an ultrapure water (or deionized water) injection apparatus. The ultrapure water is configured with a substance for chemically weakening the adhesive force between the polarizing film 62 and the display panel 61, so that the peeling of the polarizing film 62 can be more easily achieved.

The ultrapure water spray device can comprise: the ultrapure water injection section 91 is disposed adjacent to the peeling section P of the polarizing film 62, thereby injecting ultrapure water at a predetermined angle. In the ultrapure water injection section 91, the injection angle and injection pressure of ultrapure water can be controlled. In the first embodiment of the present invention, the ultrapure water injection unit 91 is positioned above the tables 11 and 12, and is configured to inject ultrapure water toward the lower portions of the tables 11 and 12 toward the peeling unit P. However, in another embodiment of the present invention, the ultrapure water injection section 91 may be located at a lower portion of the tables 11 and 12, and may be configured to inject ultrapure water toward an upper portion of the tables 11 and 12 toward the peeling section P.

The sprayed ultrapure water is recovered again in the ultrapure water recovery unit 92 disposed at the point where the ultrapure water is dropped. The ultrapure water recovery section 92 may be constituted by at least one container so as to be able to recover the falling ultrapure water. The ultrapure water recovered in the ultrapure water recovery section 92 may be supplied to the ultrapure water injection section 91 again by flowing into the ultrapure water supply section 93 constituted by a pipe by a water pump or the like.

In various embodiments of the present invention, the peeling apparatus 1 may further include: an air knife 100 is used for drying and removing residual ultrapure water on the surface of the display panel 61 of the polarizing film 62. The air knife 100 may be configured to spray high-pressure air at a predetermined angle through a spray port toward the display panel 61, which is in a wet state due to the ultrapure water, thereby removing the ultrapure water from the display panel 61.

The second embodiment of fig. 3 may further comprise at least one

heater

111, 112 compared to the first embodiment of fig. 2. The

heaters

111, 112 may be provided to heat the adhesive of the polarizing film 62 to weaken the adhesive force, so that the polarizing film 62 is more easily peeled. The

heaters

111, 112 may be configured to heat the first table 11 and/or the main body of the first support roller 70.

The first heater 111 for heating the first stage 11 may be disposed inside or below the first stage 11. The display device 60 loaded on the heated first table 11 is pressed toward the first table 11 by the first support roller 70, so that heat can be quickly obtained from the heated first table 11. The second heater 112 for heating the main body of the first support roller 70 may increase the temperature of the polarizing film 62 by applying radiant heat to the upper surface of the polarizing film 62.

In fig. 3, the

heaters

111 and 112 are shown as being in contact with the outer surfaces of the main bodies of the first table 11 and the first support roller 70, but the technical idea of the present invention is not limited thereto, and the

heaters

111 and 112 may be disposed inside the first table 11 and the second table 12 or disposed outside as separate devices and connected to the first table 11 and the second table 12, respectively.

In the third embodiment of fig. 4, the peeling roller 21 is disposed below the first table 11, compared to the first embodiment of fig. 2. In this embodiment, the display panel 61 is mounted on the first table 11 in a state where the polarizing film 62 is attached to the lower portion thereof.

The polarizing film 62 is peeled off in the same manner as described in the first embodiment of the invention. Specifically, a corner portion of the polarizing film 62 may be preliminarily separated from the display panel 61 by an operator, and then attached to the peeling roller 20 by bonding or the like. If the peeling roller 20 is rotated by means of the control device 50 such as a driving motor, the polarizing film 62 connected to the peeling roller 20 is wound up to the peeling roller 20 and peeled from the display panel 61. While the polarizing film 62 is peeled, the display panel 61 is moved in the direction X perpendicular to the peeling portion P. The display panel 61 from which the polarizing film 62 is removed by the peeling roller 20 is loaded to the second table 12 spaced apart from the first table 11 by a preset interval.

In the third embodiment of the present invention, since the peeling roller 20 is disposed at the lower portion of the first table 11, the operations between the

upper support rollers

31, 32 and the lower support rollers 41, 42 are changed from each other as compared with the first embodiment. For example, the polarizing film 62 is pressed and supported by the first lower support roller 41, and the polarizing film 62 that has just been peeled is wound around the peeling roller 20 via the outer periphery of the first lower support roller 41. The first lower support roller 41 is arranged between the peeling roller 20 and the second lower support roller 42, and the peeling angle may be changed according to the relative position of the first lower support roller 41 and the peeling roller 20.

The second lower supporting roller 42 may support the display panel 61 after the polarizing film 62 is peeled. The second lower support roller 42 is configured to be movable in a direction toward the first lower support roller 41 or in a direction away from the first lower support roller 41, and the distance between the first lower support roller 41 and the second lower support roller 42 can be controlled.

A plurality of lower support rollers 40 may be disposed in a space that separates the first table 11 from the second table 12. The plurality of lower supporting rollers 41, 42 may include: a first lower support roller 41 disposed below the first upper support roller 31; and a second lower supporting roller 42 disposed below the second upper supporting roller 32. The lower support rollers 41, 42 may be disposed adjacent to the peeling portion P of the polarizing film 62. During the period in which the polarizing film 62 is peeled, the lower supporting rollers 41, 42 may be rotated in a direction that facilitates the movement of the display device 60.

While the polarizing film 62 is peeled off, a tension in the lower direction may be applied to the display panel 61 due to an adhesive force between the polarizing film 62 and the display panel 61 to bend the display panel 61 in the lower direction at the peeling portion P. The lower supporting rollers 41, 42 may support the display panel 61 according to the curved shape of the display panel 61 while the polarizing film 62 is peeled off, thereby preventing deformation of the display panel 61 such as separation between stacked bodies of the display panel 61.

In the third embodiment of the present invention, the ultrapure water injection unit 91 is located below the tables 11 and 12, and is further configured to inject ultrapure water toward the peeling unit P and above the tables 11 and 12. The sprayed ultrapure water is recovered again in the ultrapure water recovery unit 92 disposed at the point where the ultrapure water is dropped. The recovered ultrapure water may be flowed into the ultrapure water supply section 93 and supplied again to the ultrapure water injection section 91.

The fourth embodiment of fig. 5 is configured in a manner combining the first embodiment of fig. 2 and the third embodiment of fig. 4. Such an embodiment can be applied to a case where the polarizing films 62 are attached to both sides of the display panel 61.

Referring to fig. 5, the display device 60 having the first polarizing film 62a attached to the upper surface thereof and the second polarizing film 62b attached to the lower surface thereof is mounted on the first table 11. A corner portion of the first polarizing film 62a may be preliminarily separated from the display panel 61 by an operator and then attached to the upper peeling roller 20 provided on the first table 11 by bonding or the like. If the upper peeling roller 20 is rotated by means of the control device 50 such as a driving motor, the first polarizing film 62a connected to the upper peeling roller 20 is wound up to the upper peeling roller 20 and peeled from the display panel 61. While the first polarizing film 62a is peeled, the display panel 61 is moved toward the second table 12a on the right side. The display panel 61 from which the first polarizing film 62a is removed by the upper peeling roller 20 is loaded to the right second table 12a spaced apart from the first table 11 by a preset interval.

While the first polarizing film 62a is peeled, the

upper support rollers

31b and 32b and the lower support rollers 41b and 42b disposed between the first table 11 and the right second table 12a can support the display device 60, thereby preventing deformation and damage. The operations of the

upper support rollers

31a, 32a and the lower support rollers 41a, 42a are the same as those described with reference to fig. 2.

The ultrapure water injection device constituted by the first ultrapure water injection section 91a, the first ultrapure water return section 92a, and the first ultrapure water supply section 93a injects ultrapure water to the peeling section P of the first polarizing film 62a, thereby facilitating peeling. The display panel 61, which is formed in a wet state due to the injection of ultrapure water, may be dried by the air knife 100.

The display panel 61 from which the first polarizing film 62a is removed is loaded on the right second table 12 a. Thereafter, the display panel 61 may be moved onto the first table 11 again, and one corner portion of the second polarizing film 62b is first separated from the display panel 61 and is then attached to the lower peeling roller 21 disposed at the lower portion of the first table 11 by bonding or the like. When the lower peeling roller 21 rotates, the second polarizing film 62b connected to the lower peeling roller 21 is wound around the lower peeling roller 21 and peeled from the display panel 61.

While the second polarizing film 62b is peeled, the display panel 61 is moved toward the left second table 12 b. The display panel 61 from which the second polarizing film 62b is removed by the lower peeling roller 21 is loaded to the left second table 12b spaced apart from the first table 11 by a preset interval.

While the second polarizing film 62b is peeled, the

upper support rollers

31a and 32a and the lower support rollers 41a and 42a disposed between the first table 11 and the left second table 12b can support the display device 60, thereby preventing deformation and damage. The operations of the

upper support rollers

31a, 32a and the lower support rollers 41a, 42a are the same as described with reference to fig. 4.

The ultrapure water injection device constituted by the second ultrapure water injection section 91b, the second ultrapure water return section 92b, and the second ultrapure water supply section 93b injects ultrapure water to the peeling section P of the second polarizing film 62b, thereby facilitating peeling.

In addition, the following is illustrated in fig. 5: first, the first polarizing film 62a attached to the upper surface of the display panel 61 is removed, and then the second polarizing film 62b attached to the lower surface is removed. However, the technical idea of the present invention is not limited thereto, and the second polarizing film 62b may be removed first and then the first polarizing film 62a may be removed according to implementation.

Those having ordinary knowledge in the art to which the present invention pertains will appreciate that the present invention can be embodied in other specific forms within a scope that does not change its technical idea or essential features. The embodiments described above are therefore to be understood as being in all aspects illustrative and not restrictive. The scope of the present invention is defined by the claims, rather than the detailed description given above, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts are to be construed as being included in the scope of the present invention.
