Description

TECHNICAL FIELD [0001] The present invention relates to a dispensing apparatus, a dispensing method using the dispensing apparatus, and a dispensing apparatus including the dispensing apparatus.

TECHNICAL FIELD The present invention relates to a coating apparatus, a coating method using the coating apparatus, and a coating apparatus including the coating apparatus, and more particularly, to a coating apparatus capable of easily applying a bonding agent to a coating surface of a workpiece including a curved surface, A coating method and a coating facility.

In general, as shown in FIG. 1, an organic light emitting diode includes an organic light emitting layer including upper and lower electrodes and an organic material layer on one surface, a transistor (TFT) and the like, and includes a first substrate having a rectangular shape, And is formed of a second substrate S2 covering the first substrate S1. A bonding agent is applied between the upper surface of the first substrate S1 and the lower surface of the second substrate S2 so that the first substrate S1 and the second substrate S2 are bonded to each other.

On the other hand, the organic material layer constituting the organic light emitting diode is very vulnerable to moisture and oxygen, and when moisture and oxygen enter the organic light emitting diode, there arises a problem that the light emitting characteristic and the lifetime are reduced. In addition to the primary coating step of applying the bonding agent along the upper edge of the first substrate S1 and the lower edge of the second substrate S2, the first substrate S1 and the second substrate S2 ) Is further applied to the side surface of the base material to reinforce the bonding.

As described above, the coating equipment for further applying the bonding agent along the side surface of the panel formed of the first substrate S1 and the second substrate S2 that are primarily bonded includes a coating unit having a nozzle for applying a bonding agent, A horizontal conveyance portion for moving the unit along the extending direction of the panel, and a raising and lowering portion for raising and lowering the coating unit. Here, as described above, the panel is a first junction of a rectangular first substrate and a second substrate, and the panel has a rectangular shape. Accordingly, in order to apply the bonding agent to the side surface of the panel using the application unit, the application unit is horizontally arranged in the X-axis and Y-axis directions along the side surface of the panel (the object to be bonded of Korean Patent No. 1,379,353) as disclosed in Korean Patent No. 1,379,353 The bonding agent is discharged while moving in a straight line. Thus, the application unit horizontally or linearly moves in the X-axis and Y-axis directions according to the size of the panel by the horizontal transfer unit from the application start point to the end point.

However, when the shape of the panel, that is, the side of the panel to which the bonding agent is applied is a curved line, a shape including a curved line, or a case including a curved line portion and a straight line portion (see FIG. 2) There is a limit in applying the bonding agent, and a failure occurs depending on the bonding agent application position. That is, the bonding agent is not applied to the application point to be coated, but the bonding agent is applied to the other points, and thus the separation distance to which the bonding agent is applied is uneven. Therefore, after a predetermined time thereafter, the bonding agent is volatilized by the osmotic phenomenon to form an application line, in which the thickness of the application line is uneven. In other words, the thickness or applied amount of the coating line applied along the fed direction of the application surface is not constant. Therefore, a defective product may occur due to defective application of the bonding agent, and moisture and acid may be infiltrated into a region where the amount of the bonding agent is relatively small.

Further, when the side surface of the panel includes a curved line and a straight line, there is a problem that the moving speed and the coating timing of the coating unit can not be appropriately controlled at a portion where the curved line and the straight line meet.

That is, in the present invention, when applying the bonding agent from the starting point of the application of the bonding agent to the end point of the application of the bonding agent on the coated surface of the object P, that is, on the side surface thereof,

Hereinafter, for convenience of explanation, the point where the bonding agent is discharged and applied to the side surface of the object P is referred to as "application point (D) D1 to D9". The spacing distance and the number of the dispensing points D: D1 to D9 may be variously changed depending on the shape or the size of the object P, and may be preset or predetermined dispensing points D: D1 to D9 ), The bonding agent should not be applied to the bonding agent.

Therefore, in the present invention, by controlling the movement of the coating unit 510 by using the coating control unit 530, the bonding agent is easily or accurately applied to the coating surface including the curved portions C2 and C2.

That is, in the object P having a shape as shown in Fig. 10, a plurality of application points D: D1 to D9 are located counterclockwise from the application start point to the application end point. For example, in the object P according to the embodiment, there are nine application points D1 to D9, the application start point is the first application point D1, the application end point is the ninth application point D9, The seven application points disposed between the first application point D1 and the ninth application point D9 are referred to as second to eighth application points D2 to D8 in the counterclockwise direction. The tangents of the first to ninth application points D1 to D9 are called first to ninth tangential lines.

In the above description, for the sake of convenience of explanation, it has been described that there are nine coating points D1 to D9 described above in the material to be treated, but the bonding agent is applied at a number of points.

The coating position value storage unit 531 stores the position values of the plurality of coating points D: D1 to D9. At this time, for example, the coating position (D) (D1 to D9) is determined on the basis of a mark marked on the object P or the center of the object P as a reference position (A) Which depends on the shape of the object P and the distance between the application points D: D1 to D9 to which the bonding agent is to be applied. Each coating point (D: D1 to D9) can be represented by X, Y coordinate values. For example, the coordinates of the reference position _{(A) (PX 0, PY} 0) when referred to, the coordinate values of the reference position _{(A) (PX 0, PY} 0) from X, the first to ninth spaced apart in the Y-direction position of the coating point (D1 ~ D9) is _{(PX 1, PY 1),} (PX 2, PY 2), (PX 3, PY 3), (PX 4, PY 4), (PX 5, PY 5) , (PX ₆ , PY ₆ ), (PX ₇ , PY ₇ ), (PX ₈ , PY ₈ ), and (PX ₉ , PY ₉ ).

When applying the bonding agent, the application data corresponding to the shape of the object P to be coated and the coating position interval among the plurality of kinds of the application data to be applied are selected, Becomes the coating position value of the object P to be processed.

The nozzle position value storage unit 532 stores the application position where the bonding agent is applied, more specifically, the nozzle 513a in which the discharge port of the nozzle 513a from which the bonding agent is discharged faces the application points D: D1 to D9, ) Is stored. That is, a straight line passing through the center of the discharge port of the nozzle 513a is directed to the tangent line of each coating point (D: D1 to D9) and the object P to be processed in the nozzle position value storage unit 532, The position of the nozzle 513a is stored. In other words, a straight line passing through the center of the discharge port is directed to the tangent line of the application point (D) D1 to D9 and the target P to the nozzle position value storage unit 532, To D9 of the nozzle 513a, which is a substantially normal line perpendicular to the tangent line of the nozzle 513a.

Here, each of the first to ninth nozzle position values is a positional value facing the dispensing points D: D1 to D9 while the ejection orifice of the nozzle 513a faces the object P to be processed. That is, each of the first to ninth nozzle position values is a position value that the nozzle 513a is substantially perpendicular to the outer side of the application point D (D1 to D9) and the side in contact with the application point (D: D1 to D9) . That is, the angle formed by the horizontal direction and the vertical direction on the surface f of the nozzle 513a contacting the application point from the outside of the application point D: D1 to D9 is a position value forming a substantially right angle. In other words, the nozzles 513a (513a) and 513b (513a) substantially perpendicular to the first tangent line TL1 and the second tangent line TL2, which are in contact with the application points (D: D1 to D9) outside the application points ).

The substantial right angle is a value obtained by subtracting a predetermined angle from an angle value of 90 degrees, and the angle value of the substantially right angle may be, for example, 89 to 91 degrees. Accordingly, in the present invention, the angle formed by the nozzle 513a with the outer side of each application point D (D1 to D9) and the surface in contact with the application point (D: D1 to D9) . To be more specific, the nozzle 513a and the first tangent line TL1 and the second tangent line TL2 which are in contact with the application points D: D1 to D9 outside the application points D: D1 to D9, respectively, That is, it is set to be 89 [deg.] To 91 [deg.].

That is, the nozzle 513a is substantially perpendicular to each of the first tangent line TL1 and the second tangent line TL2 which are in contact with the application points D: D1 to D9 outside the application points D: D1 to D9, And is a position value of the nozzle 513a which is 89 [deg.] To 91 [deg.].

The plurality of nozzle position values are stored as values satisfying the above-described conditions with respect to any one mark marked on the object P or with the center of the object as a reference position. And, each nozzle position value can be expressed by X, Y, and θ values. For example, when the coordinates of the reference position A are (X ₀ , Y ₀ , θ ₀ ), the coordinates of the reference position (A) are calculated based on the coordinate values (DX ₀ , DY ₀ , Dθ ₀ ) nozzle position value _{(DX 1, DY 1, Dθ} 1), (DX 2, DY 2, Dθ 2), (DX 3, DY 3, Dθ 3), (DX 4, DY 4, Dθ 4), (DX _{5, DY 5, Dθ 5)} , (DX 6, DY 6, Dθ 6), (DX 7, DY 7, Dθ 7), (DX 8, DY 8, Dθ 8), (DX 9, DY 9, Dθ ₉ ). ≪ / RTI >

When the bonding agent is discharged and applied in this state, the bonding agent is accurately applied to the second application point D2.

Hereinafter, the application method at the third application point to the ninth application point (D3 to D9) will be omitted, but the application method at the first and second application points (D1, D2) . Therefore, the first to ninth application points D1 to D9 can be accurately applied.

The curing unit 600 is located in front of the application device 50 by curing the bonding agent applied to the side surface of the article P, that is, the bonding agent. The curing unit 600 includes a first stage unit 100a and a second stage unit 100b which are arranged and arranged by a medium for curing the bonding agent such as a curing unit 610 for radiating ultraviolet rays (UV) And a horizontally moving unit 620 in the X-axis direction. The curing unit transfer unit 620 is installed between a guide member (hereinafter referred to as a curing unit guide member 621) extending in the X axis direction and a curing unit 610 and a curing unit guide member 621 to support the curing unit 610 (Hereinafter referred to as a curing machine moving block 622) that slides along the curing machine guide member 621 in a state of being in a state of being lifted.

The buffer unit 700 is a means for separating and supporting the object P coated with a bonding agent from the stage units 100a and 100b and then waiting for a predetermined time before entering the curing unit 610. [ This buffer unit 700 is provided on the movement path of the first stage unit 100a in the Y axis direction between the application device 50 and the curing device 610 and is moved from the first stage unit 100a A first buffer 710a for supporting the object to be processed and a second stage unit 100b provided on the moving path in the Y axis direction of the second stage unit 100b for supporting the object P from the second stage unit 100b And a second buffer 710b.

Each of the first and second buffers 710a and 710b has a picker capable of holding and fixing the object P and more effectively has a plurality of pickers in the buffers 710a and 710b. For example, each of the first buffer 710a and the second buffer 710b includes first and second pickers. Each of the first and second pickers supports the object P with a vacuum attraction force, and is positioned above the stage units 100a and 100b. The first and second pickers separate the article to be processed from the stage units 100a and 100b through the ascending and descending operations and stand by for a predetermined time and then wait for the predetermined time and again place the article P on the stage units 100a and 100b, .

Hereinafter, the operation and application method of the coating equipment according to the embodiment of the present invention will be described with reference to FIG. 3 to FIG. In the present invention, the first stage unit 100a, the first prealigning unit 200a, the first buffer unit 710a, the second stage unit 100b, the second prealigning unit 200b, The operations of the first stage unit 100a and the first prealigning unit 200a will be described first and the bonding agent is applied to the workpiece P to be processed .

First, the object P is drawn into a coating facility and placed on the first stage unit 100a. Then, the workpiece placed on the first stage unit 100a is primarily aligned by using the first pre-alignment unit 200a. That is, when the object P is placed on the first stage unit 100a, the stage transfer unit 400 moves the first stage unit 100a to the first pre-alignment unit 200a. At this time, the object to be processed is placed in the space partitioned by the arrangement of the pair of the alignment members 210 of the first pre-alignment unit 200a, that is, the inner space of the pair of alignment members 210 (See Fig. 7A). The first stage unit 100a is moved horizontally in at least one of the X axis direction and the Y axis direction by using the stage transfer unit 400 and the stage 110 is rotated using the stage rotation axis 120 The object to be processed P is brought into contact with the inner surface of the uni-line member 210 and the other area of the other object 210 on the inner side of the other aligning member 210 . That is, as shown in FIG. 7B, the second linear portion SL2 of the article P is in contact with the inner surface of the unaligned member 210, and one of the points of the second curved portion C2 When the stage 110 is moved so as to contact the inner surface of the other alignment member 210, the first alignment using the first pre-alignment unit is terminated.

Thereafter, for the secondary alignment, the stage transfer unit 400 positions the first stage unit 100a to the image pickup section 311. Then, At this time, the first stage unit 100a is positioned below the image pickup unit 311, and the image pickup unit 311 picks up the object P placed on the first stage unit 100a from above , And can be displayed on the display unit 313 in real time.

The stage transfer unit 400 moves the first stage unit 100a horizontally along the X axis and the Y axis so that the image of the object P is displayed on the display unit 313, The reference alignment mark M0 of the display portion 313 and the alignment mark MP of the object to be processed are positioned as shown in Fig.

Subsequently, the target-material aligning unit 320 analyzes the image of the object P picked up by the image pickup unit 311, analyzes the shape of the object P, And controls the rotation of the stage rotation axis 120 of the target alignment mark MP so that the target alignment mark MP is aligned with the reference alignment mark M0. That is, the shape of the object to be processed is determined by calculating the outermost points or lines of the image of the picked up object P as (X, Y) coordinate values and analyzing a plurality of (X, Y) And the shape of the object P to be processed is transmitted to the application position value storage unit 531 and the nozzle position value storage unit 532 by the application control unit 530.

The image analyzing unit 312 of the aligning unit 320 analyzes the image of the object P picked up by the image pickup unit 311 and determines the position of the alignment mark MP of the object to be processed . Then, the comparator 323 compares the detected position of the to-be-processed object alignment mark MP with the reference alignment mark M0. The stage alignment unit 324 rotates the stage rotation axis 120 to rotate the stage rotation axis 120 in a direction perpendicular to the surface of the target alignment mark M0, So that the water alignment mark MP coincides with the reference alignment mark M0 as shown in FIG. 8B.

The secondary alignment of the object P is terminated by the imaging unit 310 and the aligned object aligning unit 320 and the stage transfer unit 400 is operated to move the first stage unit 100a And the application transfer unit 520 is operated to move the application unit 510 to the application position.

Next, the application device 50 is operated to sequentially apply the bonding agent to the application surface of the object P, that is, a plurality of application positions on the side surface.

To this end, the application control unit 530 receives the shape data of the object P analyzed by the image analysis unit 312 of the object aligning unit 320. One of the plural kinds of application position value data stored in the application position value storage unit 531 is selected for each shape of the object P to be processed and stored in the nozzle position value storage unit 532 for each shape of the object to be processed And selects one of plural kinds of nozzle position value data.

For example, when the shape of the object P analyzed by the image analyzer 312 is a shape shown in FIG. 10, that is, between the first rectilinear section SL1 and the second rectilinear section SL2 facing each other The first curved portion C1 and the second curved portion C2 may be connected to each other. When analysis of the shape of the object P is completed in the image analysis unit 321, among the plurality of kinds of the coating position value data stored in the coating position value storage unit 531, the above described object P And selects the data of the above-described object P among a plurality of types of nozzle position value data stored in the nozzle position value storage unit 532, and applies the selected data to the actual coating process.

That is, the application control unit 530 controls the position of the nozzle 513a through the selected application position value and the nozzle position value, and applies the bonding agent to each application position. At this time, for example, the bonding agent is applied to the ninth coating point D9 while the first coating point D2 is moved counterclockwise with the coating start point.

That is, first, in order to apply the bonding agent to the first application point D1, the nozzle of the application unit 510 is moved in the X-axis and Y-axis directions so as to be positioned at (DX ₁ , DY ₁ ). The nozzle position control unit 533 controls the application rotation unit 513c of the application unit 510 so that the nozzle position control unit 533 is disposed outside the first application point D ₁ at a substantially right angle with the surface in contact with the application point D1 So that the angle between the nozzle 513a and the reference position becomes D? ₁ . In other words, the tangential line TL of the first application point D1 and the nozzle extension line NL passing through the center of the nozzle 513a toward the target object P form a straight line substantially perpendicular to the tangent line TL That is, the angle formed between the nozzle 513a and the reference position becomes D? ₁ so as to become a substantially normal line.

Accordingly, the discharge port of the nozzle 513a is arranged to face the first application point D1 of the object P, more specifically, the nozzle 513a facing the object P passing through the center of the discharge port Is perpendicular to the tangent line perpendicular to the tangent line of the first application point D1. When the bonding agent is discharged and applied in this state, the bonding agent is accurately applied to the first application point D1.

Subsequently, the bonding agent is applied to the second application point D2. The nozzle position control unit 533 controls the application transfer unit 520 to move the nozzle 513a of the application unit 510 in the X axis direction and the Y axis direction so as to be positioned at DX2 and DY2.

Then, the nozzle position control portion 533 is applied to control the applied rotation unit (513c) of the unit 510, the second application point (D ₂₎ surface and substantially perpendicular to the outside in contact with the second application point (D ₂₎ of the So that the angle formed between the nozzle 513a and the reference position is D? ₂ . The discharge port of the nozzle 513a is arranged so as to face the second application point D ₂ of the object P and more specifically the nozzle 513a passing through the center of the discharge port and facing the article P 513a is perpendicular to the tangent line perpendicular to the tangent line of the second application point D ₂ . When the bonding agent is discharged and applied in this state, the bonding agent is accurately applied to the second application point (D ₂ ).

Hereinafter, the application method at the third application point to the ninth application point (D ₃ to D ₉ ) will be omitted, but the application method at the first and second application points (D ₁ , D ₂ ) The application is carried out in the same manner as in the first to ninth application points D ₁ to D ₉ .

When application of the bonding agent is completed to the first to ninth application points D1 to D9 of the article P to be placed on the first stage unit 100a, the application device 50 is moved to the second stage unit 100b To the position to which the bonding agent is applied.

Meanwhile, the first stage unit 100a is moved in the Y axis direction through the stage transfer unit 400 and positioned below the first buffer 710a. Then, any one of the first and second pickers of the first buffer 710a, for example, the first buffer 710a is lowered to attract and support the object P placed on the first stage unit 100a, For example, 10 minutes. At this time, the first stage unit 100a in which the object P is separated again moves in the direction in which the first pre-alignment unit 200a is located, that is, in the backward direction, and moves the object P A primary alignment (pre-alignment), a secondary alignment, and a bonding agent are performed. Thereafter, the first stage unit 100a supporting the object P to which the bonding agent is applied is transferred again to the first buffer 710a, and the second picker is placed on the first stage unit 100a And adsorbs and supports the object P to stand by for a predetermined time. The first picker is lowered to place the object P waiting on the first picker on the first stage unit 100a and the first stage unit 100a is moved to the position of the curing unit 610, And moves horizontally to pass through the lower side. The first stage unit 100a moves horizontally to be positioned on the moving path of the first stage unit 100a and the second stage unit 100b is moved in the radial direction of the first stage unit 100a as the first stage unit 100a moves below the curing unit 610, The binder is cured by ultraviolet rays.

The object P to which the bonding agent is cured is unloaded from the first stage unit 100a and drawn out to the outside, and the first stage unit 100a moves backward in the direction in which the first buffer 710a is located . Then, the object P supported by the second picker is loaded on the upper portion, and the first stage unit 100a moves again to the lower side of the curing unit 610 to cure the bonding agent.

Then, the first stage unit 100a moves again in the direction in which the first pre-alignment unit 200a is positioned, that is, moves backward, and performs a primary alignment (pre-alignment) , Secondary aligning and bonding agent application process.

The second stage unit 100b moves while alternately or alternating with the first stage unit 100a while applying the bonding agent while moving the first stage unit 100a as described above, ) Is performed. That is, while the bonding agent is applied to the object to be processed placed on the first stage unit 100a, another object P to be processed is placed on the second stage unit 100b, We proceed in person. While the application of the bonding agent to the article P to be placed on the first stage unit 100a is completed and the movement of the first stage unit 100a to the first buffer 710a and the hardening of the bonding agent And the object to be treated is applied on the two stage unit 100b. Then, the curing of the material to be processed (P) seated on the first stage unit 100a is completed again, and the first stage unit 100a and another to-be-processed object P are placed, And moves the second stage unit 100b to the second buffer 710b and hardens the bonding agent while applying the cold aligning or bonding agent.

As described above, in the present invention, by using the application control unit 530, the nozzles 513a are arranged at the application points D: D1 to D9 outside the application points at the application points D: D1 to D9, And the angle of the nozzle 513a is adjusted so that the nozzle 513a is disposed at a substantially right angle. It is easy to apply the bonding agent to each of the plurality of application points D: D1 to D9 on the application surface of the object P including the curved surface and the application agent is applied accurately to the application points D: D1 to D9 can do. Therefore, when the bonding agent is diffused by the osmotic phenomenon after application of the bonding agent, the bonding agents applied to the plurality of application points (D: D1 to D9) are interconnected to form an application line, in which the thickness of the application line is uniform. That is, the bonding agent is applied in a uniform amount along the extending direction of the coated surface. As a result, it is possible to prevent the occurrence of product defects due to nonuniform application of the bonding agent.
