The touch panel is actively applied to all display devices as an input means for inputting predetermined information corresponding to the display by pressing the display displayed on the panel.

In general, the touch panel extracts coordinates of a portion pressed on a touch panel by an electrostatic capacity method, a resistance film method, a surface ultrasonic method, an infrared method, or the like, and inputs information.

Since the touch panel is a method in which a hand or an electronic pen or the like touches the panel to recognize coordinates, panel damage is apt to occur. Therefore, a window for protecting the touch panel is manufactured by attaching it on the touch panel.

Conventionally, a method of using an optical adhesive (OCA tape) or using a UV curable resin is used as a method of attaching the touch panel and the window.

In the case of using the optical adhesive, the entire thickness of the panel increases due to the thickness of the adhesive itself, and there is a problem that the adhesive strength is lowered. Therefore, a UV curing method using UV resin is widely used.

However, in the conventional method of applying UV resin, since the UV resin must be applied to the entire surface of the glass, there is a problem that the cost of UV resin increases and the manufacturing cost increases.

In addition, there is a problem that the UV resin flows down due to the flowability of the coated UV resin when the window and the touch panel cell are bonded or cured after the UV resin is applied, or the uniformity of the UV resin is decreased and the defect rate is increased.

The UV lamp is characterized in that only the UV lamp disposed at the front end in the direction in which the discharge nozzle advances is turned on to carry out the hardening.

Meanwhile, the method of applying UV resin according to the present invention includes a step of discharging a UV dam to an edge region of a window surface, and discharging UV dots into the discharged UV dam.

FIG. 1 is a layout diagram schematically showing a touch panel laminating stage according to a preferred embodiment of the present invention, and FIG. 2 is a flowchart schematically showing a laminating method according to the arrangement of FIG.

1 and 2, a method of attaching a touch panel according to the present invention will be described.

Here, each part of the stage shown in Fig. 1 may be connected via a conveyor belt or conveyed through a conveying robot, or a combination of a conveyor belt and a robot arm may be applied.

First, when the touch panel cell is loaded on the stage, the protective film removing unit 110 removes the protective film from the touch panel cell through the filler.

Here, since the protective film is bonded by low adhesive force as a means for protecting the window surface, the protective film can be removed by applying a force larger than the adhesive force. In addition, the protective film can be removed by manual operation.

Then, the bonding surface area is increased to increase the adhesive force, and plasma processing is performed through the plasma processing part 120 to remove organic substances on the touch panel cell.

The plasma treatment may be performed in an atmosphere of oxygen (O ² ) or nitrogen (N ² ), and the specific conditions may vary according to the specification, and are generally well-known technologies, and thus a detailed description thereof will be omitted.

Then, the plasma-processed touch panel cell is transferred to the first load lock chamber 311 of the chamber part 30. [

The plasma processing unit 120 may further include a rotation unit 130 for rotating the touch panel cell 180 degrees between the plasma processing unit 120 and the first load lock chamber 311.

The touch panel cell is positioned at an upper portion of the touch panel and the upper surface of the touch panel is downward. However, since the touch panel cell initially loaded on the protective film removing unit 110 is loaded with the upper surface of the panel facing upward, And the rotation unit 130 rotates the touch panel cell 180 degrees by using a rotating device or a robot and transfers the rotation to the first load lock chamber 311. [

The first load lock chamber 311 may be formed as small as possible as long as the touch panel cell can be inserted. When the gate of the first load lock chamber is opened and the gate of the touch panel cell is closed, The pressure between atmospheric pressure and several torr can be controlled to act.

On the other hand, when the window is loaded on the stage, if the protective film is attached on the window, the protective film is removed from the window through the filler in the protective film removing unit 210.

Then, the plasma processing is performed through the plasma processing unit 220 to increase the adhesive surface area to increase the adhesive force and to remove organic substances on the window.

After the plasma treatment, it is transferred to the UV resin application device 50 to apply UV resin to the window surface.

Fig. 3 is a system structural view schematically showing a UV resin application apparatus according to a preferred embodiment of the present invention, and Fig. 4 is a sectional view of the stage portion of Fig.

3 and 4, a UV resin coating apparatus 50 according to a preferred embodiment of the present invention includes a stage 510 in which a window is loaded and moved, a first discharging unit 520 discharging a UV dam, A second ejection unit 530 for ejecting UV dots into the UV dam, and a discharge control unit (not shown) for controlling the operations of the first ejection unit and the second ejection unit.

A stage cylinder 540 for vertically moving the stage for moving and transporting the window loaded on the stage, an aligning cylinder 550 for pushing the window for alignment after window loading, A fixing cylinder 560 for pushing and fixing to the substrate chuck, and a robot arm 570 for transporting the window coated with the UV resin.

The stage 510 may be configured as a conveyor belt capable of moving back and forth.

The first discharging unit 520 and the second discharging unit 530 are respectively connected to the X-axis guide portions 521 and 521 for guiding movement in the X-axis direction and the Y- Axis guide portions 522 and 532 for guiding axial movement, and nozzle portions 523 and 533 connected to the Y-axis guide portion and moving in the Y-axis direction.

3, guide means for guiding the X-axis horizontal movement direction of the Y-axis guide portions 522 and 532 are provided between the X-axis guide portions 521 and 531 and the Y-axis guide portions 522 and 532 desirable. As described above, the Y-axis guide portions 522 and 532 horizontally move in the X-axis direction in the same manner as they horizontally move by the driving force of a driving motor (not shown).

Guide means may also be provided between the Y axis guide portions 522 and 532 and the nozzle portions 523 and 533 in the same manner as guide means formed between the X axis guide portions 521 and 531 and the Y axis guide portions 522 and 532.

The guiding means may be modified in various ways as long as it has a structure capable of accurately guiding a linear motion like a linear guide.

Here, the X-axis means movement in the horizontal direction, and the Y-axis means the movement in the vertical direction.

The nozzle unit of the first discharge unit may include a discharge nozzle 523a for discharging the UV resin and four UV lamps 523b arranged in the vertical and horizontal directions of the discharge nozzle, as shown in FIG. 5A.

When the direction of the discharge nozzle is changed, the conventional UV lamp is turned off and the direction in which the discharge nozzle advances The UV lamp located at the front end is turned on, so that the hardening progresses.

Since the UV resin requires high adhesion to the dam, a UV resin for high viscosity can be used, and a UV resin for low viscosity can be used for the dot.

When the window is transported in a state where the UV resin is not cured, it is preferable that the UV resin is flowed to the periphery to affect the uniformity of the UV resin, and therefore it is desirable to reduce the adhesive strength to about 10 to 30% of the total adhesive force after application of the UV resin.

Hereinafter, a UV resin application method according to a preferred embodiment of the present invention will be described.

First, the window is loaded at the first position A of the stage 510, the stage cylinder 540 is elevated, and the aligned cylinder 550 fixes the window.

More specifically, in a state in which the stage cylinder 540 is lowered, the window is positioned on the first position A by the robot d arm, the stage cylinder 540 is moved upward, and the window is loaded in the first position A do. Next, the position of the window is aligned through the aligning cylinder 550, and the fixing cylinder 560 is pushed to fix the window to the substrate chuck 511.

The substrate chuck 511 and the fixed cylinder 560 are moved in conjunction with movement of the conveyor belt of the stage.

The window on the stage 510 then moves to the second position B for UV resin application.

FIG. 5 shows a process of applying UV resin on the window surface, FIG. 5A shows a process of forming a UV dam, FIG. 5B shows a process of forming a UV dot, FIG. 5C shows a process in which a UV resin is applied Respectively.

5, the displacement sensor of the first discharge unit 520 extracts a reference point, aligns the reference point with the reference point, and discharges the UV dam to the window border area while moving according to the control of the discharge control unit.

Here, the discharge nozzle 523a of the first discharging unit linearly moves and discharges the UV resin until it reaches the reference point position along the edge of the window. Here, the UV resin nozzle may be composed of multiple nozzles, and the number of the nozzles may be determined according to the size of the UV dam.

As described above, the UV resin nozzle discharges the UV dam and the UV lamp operates to perform the hardening.

More specifically, as shown in FIG. 5A, the UV curing is performed in accordance with the application of the UV resin in such a manner that only the UV lamp located in the same direction as the UV resin nozzle is turned on and the remaining three UV lamps are turned off.

When the UV dam and the hardening are performed as described above, the first discharging unit 520 returns to the original position, the displacement sensor of the second discharging unit 530 extracts the reference point, aligns with the reference point, UV dots are ejected into the UV dam while moving. The UV dot may be ejected while the ejection nozzles move according to the set interval as shown in FIG. 5B.

6A. In this case, the second ejection unit 530 may include a UV tote, not the UV tote as shown in FIG. 6B, inside the UV dam Respectively.

The multi-nozzles are arranged at regular intervals d. The spacing d is set in consideration of the size of the nozzles and the degree of spreading of the UV resin. When the distance d is excessively large, If the spacing d is too narrow, the neighboring UV dot lines may overlap and the UV resin may be applied non-uniformly, so that the spreading causes the neighboring UV dot lines to be spaced at a fine contact distance .

More specifically, the second discharging unit 530 aligns with the reference point and applies UV resin through the multi-nozzle while moving in one direction, thereby forming a UV dot line inside the UV dam.

The reference point may be a top surface, a bottom surface, a left surface, or a right surface. If the reference point is the top surface, the second discharging unit moves downward to form a vertical UV tote line. The UV dot line of the vertical direction is formed while moving upward.

On the other hand, when the reference point is the left side, the second discharging unit moves to the right side to form the UV dot line, while when the reference point is the right side, the second discharging unit moves to the left side to form the horizontal UV dot line.

7A. In this case, the second discharging unit 530 may be formed by a UV damper that is not a UV tote as shown in FIG. 7C but a UV damper .

Therefore, it is possible to apply the UV resin to the entire UV dam interior and apply the UV resin in a tight and uniform manner, so that the bonding force can be increased.

More specifically, the second discharging unit 530 aligns with the reference line and applies UV resin through the slit nozzle while moving in one direction, thereby forming a UV dot surface inside the UV dam.

Here, the UV dot surface is formed while the reference line is moved to the lower surface of the upper surface, the UV dot surface is formed while moving to the upper surface of the lower surface, the UV dot surface is formed while moving to the right side of the left surface, A UV dot surface can be formed while moving.

In the above embodiment, UV dots, dot lines, and dots are formed inside the UV dam after the UV dam is formed and the UV dams are formed. However, the UV dots may be formed and the UV dots may be formed without tack formation. At this time, since the formation of the UV dam is not necessary, the first discharge unit 520 is removed, but the first discharge unit 520 can be configured to be replaced with the temporary hardening means for hardening the rim on which the UV dot surface is formed .

More specifically, after the second discharge unit 530 is constituted by a slit nozzle and moves leftward or rightward or up and down to form a UV dot surface, the edge portion may be made tapered to complete UV application.

In this case, as shown in FIG. 8, the width of the UV dot surface is an area excluding the edge portion, the UV resin is filled up to the edge portion by the spread formed by the UV dot surface, and the UV resin is flowed to the edge of the edge portion Can be prevented.

Therefore, it is important to determine the width of the UV dot surface, and it is desirable to design the nozzle so that it does not flow to the outside of the frame when the UV dot surface is formed primarily in consideration of the size of the nozzle and the degree of spreading of the UV resin.

When the UV dot ejection is completed, the second ejection unit returns to its original position.

Then, the window on the stage moves to the third position (C).

When the window moves to the third position C, the robot arm 570 disposed at the third position C temporarily grips the window fixed to the substrate chuck, and the glass fixed cylinder 560 The stage cylinder 540 is lowered and the stage is moved backward so that the substrate chuck 511 and the fixed cylinder 560 return to the first position A. [

In this state, a new window is loaded at the first position (A), and the stage cylinder is elevated so that the window gripped by the robot arm is placed on the stage at the third position (C).

Then, the window is moved to the fourth position (D) and transferred to the second load lock chamber.

The UV resin is applied to the newly loaded window by the same process as described above.

When UV resin is applied on the window, it is transferred to the second load lock chamber 312 of the chamber part.

The second load lock chamber 312 may also be formed as small as possible as long as the window can be inserted. When the window is loaded while the gate of the second load lock chamber 312 is opened and the gate is closed, To-torr < / RTI >

When the touch panel cell and the window are transferred to the chamber through the above process, the transfer robot of the transfer chamber opens the gate of the first load lock chamber 312 to take out the touch panel cell and open the gate of the process chamber 330 Loading.

Similarly, the transfer robot of the transfer chamber 330 opens the gate of the second load lock chamber 312 to take out the window and load it into the process chamber 330.

The transfer robot mounted on the transfer chamber 320 may be configured in two stages, and may be configured to include a joint robot to transfer the window and the touch panel cell to the process chamber 330 at the same time.

Here, the pressure of the transfer chamber 320 may be controlled through pumping so as to be in the range of several torr to 10 ^-2 torr, and the pressure of the process chamber 330 in which the adhesion is progressing may be controlled to 10 ^-4 to 10 ^-5 torr < / RTI > range.

As described above, when the pressure in the load lock chamber, the transfer chamber, and the process chamber is set to be decreased stepwise, the time for pumping to maintain the pressure when the gate is opened to be transferred to each chamber can be reduced, .

When the touch panel cell and the window are mounted on the process chamber 330, the touch panel cell and the window are aligned with each other by aligning means, and the touch panel cell and the window are bonded together in a vacuum state.

The process chamber 330 may be configured to be vacuum-bonded as shown in FIG.

The process chamber 330 may include fixing means, aligning means, cementing means, and hardening means.

The fixing unit includes a substrate chuck 331 on which a touch panel cell and a window are mounted at a lower end and to which a window is fixed, and an adhesive pad 332 for fixing the back surface of the touch panel cell such that an upper surface of the touch panel cell faces downward And the like.

The aligning means includes a camera stage 333 for visually confirming an alignment image indicative of an accurate position at which the touch panel cell and the window are to be attached, and a camera stage 333 for fixing both ends of the window loaded on the substrate chuck, And a touch panel aligning part 335 for performing alignment by moving the second substrate chuck in which the touch panel cell is loaded by X, Y, Z, and θ 4 axes, .

The camera stage 333 may further include an illumination unit for brightening the alignment region in order to accurately grasp the alignment image.

Here, the adhesive pad 332 may be made of a synthetic rubber having adhesiveness so as to support the touch panel cell in order to hold the touch panel cell at the upper portion. When the adhesive force is too high, The cell surface may be damaged. If the adhesion force is excessively low, the touch panel cell may be separated and broken before being attached to the window. Therefore, it is desirable that the touch panel cell has adhesiveness within a range that does not exert an excessively large adhesive force while holding the touch panel cell. And preferably has an adhesive force in the range of 400 to 5000 _gf / cm < ² >.

The temporary hardening unit may include a UV lamp 336 disposed under the process chamber and UV-curable the touch panel cell and the window.

10 and 11 schematically illustrate a process of attaching a touch panel cell and a window in a process chamber according to a preferred embodiment of the present invention. And FIG. 11 shows that the window is loaded and aligned and then joined together with the touch panel cell.

10 and 11, when the touch panel cell is loaded on the substrate chuck 331 in the process chamber 330, the position of the touch panel cell loaded with the touch panel alignment portion 335 and the position of the pressure pad 332, So that the touch panel cell is attracted to the adhesive pad 332 (FIG. 10 (b)).

Then, the 1 to 2 mm adhesive chuck is moved upward through the Y axis control of the touch panel aligning part 335, and the aligned image of the touch panel cell is recognized through the camera stage 333 (see FIG. 10 c), Fig. 12)

Then, the touch panel cell is moved upward to prevent interference with the window (Fig. 10 (d)).

Next, when the window is loaded on the substrate chuck 331 (FIG. 11E), the window aligning portion 334 fixes both ends of the window loaded in the first substrate chuck and performs centering and alignment (Fig. 11 (f), Fig. 12)

Then, the touch panel aligning unit 335 moves the touch panel cell located at the upper side downward, and moves the X, Y, Z, and θ axes to align the alignment image of the touch panel cell and the window, (Fig. 11 (g), Fig. 12)

When the alignment is completed as described above, the toughening process is performed to provide the minimum fixing force in a state in which the touch panel cell and the window are coupled as described above (FIG. 11 (h)).

For this, a UV lamp 336 may be provided at the lower end of the process chamber, and the UV lamp may be irradiated while the touch panel cell and the window are laminated so that the touch panel cell and the window can be cemented together with a minimum fixing force .

When the touch panel cell and the window are cured through the provisional curing process as described above, the adhesive pad is moved upward and separated.

Here, the window is fixed to the window aligning part 335, and the window and the touch panel cell are in a state in which adhesive strength is formed by the hardening of the UV lamp, and the adhesive force is set larger than the adhesive force of the adhesive pad, The adhesive pad 332 can be separated from the touch panel cell.

The first load lock chamber and the second load lock chamber may further include alignment means for aligning the position of the window with the touch panel cell.

In this case, the first load lock chamber 311 and the second load lock chamber 312 can align the position of the touch panel cell and the window to the correct position, Batch and process can be eliminated.

In general, the touch panel cells and windows are aligned in the process chamber through the alignment images formed on the substrate chucks of the first and second load lock chambers 311 and 312, in which the touch panel cells and the windows are mounted, Pre-alignment is possible.

More specifically, the touch panel cell and the window are aligned at the correct positions according to the X-axis, Y-axis, Z-coordinate and angle (?) Preset for alignment in the first and second load lock chambers 311 and 312, Setting the precise travel path of the transfer robot of the chamber can load the touch panel cell and window in the correct position in the process chamber 330 to remove the alignment process and means within the process chamber 330 .

When the touch panel cell and the window are bonded together in a vacuum state through the process chamber as described above, they are transferred to the UV hardening unit 410 by the transfer robot of the transfer chamber.

In the UV curing part, the UV lamp is irradiated to completely cure the UV resin, thereby bonding the touch panel cell and the window bonded together in the process chamber to each other.

The UV curing part may be sized in consideration of the length of the stage, the moving speed, and the UV irradiation intensity of the UV lamp.
