The present invention relates to a liquid adhesive applying method and apparatus for applying an active organic light emitting diode to which a liquid adhesive is applied along an edge of an adhesive surface of an active matrix organic light emitting diode (AMOLED) composed of two glasses, More specifically, simply placing a tray filled with an active organic light emitting diode in a loading position, the loading picker sequentially adsorbs and moves the active organic light emitting diode to the adhesive surface edge of the active organic light emitting diode. The present invention relates to a liquid adhesive coating method and an apparatus of an active organic light emitting diode to automatically apply a liquid adhesive and then unload to another tray to cure.

In general, organic light emitting diodes are self-emitting diodes that electrically excite fluorescent organic compounds to emit light.

This is roughly divided into a passive matrix method and an active matrix method according to a method of driving N × M pixels arranged in a matrix form.

The active matrix organic light emitting diode (AMOLED) has less power consumption than the passive matrix method, which is suitable for large area and has a high resolution.

The active organic light emitting diode is divided into a top emission type or a bottom emission type organic light emitting diode and an organic light emitting diode which is simultaneously provided with the top emission type and the bottom emission type according to the emission direction of the light emitted from the organic compound.

A rotator unit 15 is provided to change the direction by holding the side in a vertical state.

In the exemplary embodiment of the present invention, the loading unit 13 includes a tray 12 containing the organic device 1 for driving the cylinder 47, as shown in FIGS. 2 and 4 to minimize the area of the device. Therefore, the loading plate 49 is horizontally loaded on the loading plate 49 rotating about the shaft 48, and then the rod of the cylinder 47 is pushed, and the loading plate 49 rotates 90 ° about the shaft 48. It was configured to maintain the vertical state.

Accordingly, the holding means 14a is driven by 90 ° by driving another cylinder 14b installed in the loading picker 14 while the loading picker 14 moves to hold the organic element 1 contained in the tray 12. Rotating so as to enter directly below the organic element 1 contained in the tray 12, and then slightly adsorbed while rising, exited from the tray 12, the loading picker 14 is returned to the initial position (upper part of the rotator) In the moving process, the holding means 14a was reconfigured to re-drive the cylinder 14b.

However, even if the area of the device is increased by the length of one cross section of the tray 12, the organic element 1 contained in the tray 12 can be transferred to the rotator portion 15 without rotating in the process of moving the loading picker 14. It is to be understood that the tray 12 may be loaded and transported in the loading unit 13 in a horizontal state.

The rotator portion 15 for changing the direction by holding the side surface of the organic device 1 in a vertical state is installed in the mounting plate 16 fixed to the frame 11 and guides as shown in FIGS. 10 and 11.

And a suction block 21 for adsorbing the side surface of the organic device 1 as the vacuum pressure is applied to the vacuum forming hole 21a formed on the side surface, and fixed to one side of the elevating plate 18. It is composed of a motor 23 connected to the suction block base 20 by a shaft 22 to rotate the suction block base 20.

At this time, at least one vacuum forming hole 21a is formed on the side surface (surface on which the organic element is adsorbed) of each adsorption block 21, and the adsorption surface on which the organic element 1 is adsorbed is shown in FIG. As described above, a coating layer 21b of diamond, teflon, perylene, and the like having excellent abrasion resistance is formed.

The rotator portion 15 having the above-described configuration is raised and lowered by the raising and lowering means 24 to the application position 25 and the rotating position 26 or the positioning position, and the raising and lowering means 24. Is fixed to the mounting plate 16, the shaft 27 is fixed to the elevating plate 18, and the vertical movement of the elevating plate 18 to move up and down in accordance with the driving of the drive unit 28 It consists of a guide unit 17 for guiding the.

At this time, the driving unit 28 may be applied to the pneumatic cylinder, etc., the guide portion 17 is fixed to the bottom surface of the guide member 17a and the elevating plate 18 fixed to the four corners of the mounting plate 16 The guide rods (17b) are fitted to the guide member (17a), respectively, but can be applied in various forms is not necessarily limited thereto.

The loading picker 14 has an indentation groove formed in the tray 12 in the process of holding the organic device 1 in the tray 12 and accurately adsorbing the adsorption block 21 of the rotator unit 15. Tolerance of the insertion groove 12a and the adsorption of the loading picker or the adsorption in the adsorption block are generated, so that the organic device 1 is adsorbed to the adsorption block 21 of the rotator unit 15 and then the It is more preferable that the rotator portion 15 further includes a positioning portion 29 for repositioning.

In one embodiment of the present invention, the positioning unit 29 is installed to face both sides of the elevating plate 18, and the pair of positioning blocks simultaneously move toward the organic element 1 adsorbed by the adsorption block 21. 30 and a servomotor 31 for driving the positioning block. The positioning block 30 has a vertical guide surface 30a for determining the position of the organic element 1 in the X-axis direction. And a horizontal guide surface 30b for determining the position in the Y-axis direction.

At this time, if the rod 32 made of a material such as engineering plastic is fixed to the horizontal guide surface 30b, scratches may occur or damage may occur in the process of re-determining the position of the organic device 1. ) Is more preferable since it does not work.

FIG. 8 is a perspective view showing the loading picker and the unloading picker in the present invention, wherein the shafts of the servo motor 31 constituting the positioning unit 29 are arranged at predetermined intervals in the pulleys 44a and 44b. The timing belt 50 is fastened to the pulley and the timing belt 52 is also fastened to the pulley on the opposite side connected to the shaft 51 fixed to the pulley in which the servo motor 31 is not installed. When the positioning blocks 30 are fixed to the respective timing belts 50 and 52, both sides of the rotator portion 15 when the position of the timing belts 50 and 52 are changed according to the drive of the servomotor 31. The pair of positioning blocks 30 located at the same time move inwards or away.

On the other hand, above the rotator portion 15, an X-Y robot provided with a liquid adhesive coating portion 33 on the frame 11, which applies a liquid adhesive to the edge of the organic element 1 located at the coating position 25. Reference numeral 34 denotes movement along the X-Y axis direction.

The liquid adhesive applying unit 33 is an application means 37 for spraying the liquid adhesive to the edge side of the organic device 1, and X for moving the application means 37 to the liquid adhesive application site of the organic device 1 It consists of the Y robot 34.

In this case, a coating nozzle for directly applying a liquid adhesive to the organic device 1 may be used as the coating means 37, but a jetting valve for spraying the liquid adhesive at a distance of about 1-2 mm from the organic device 1 may be used. A jetting valve is more advantageous in terms of productivity.

On the opposite side of the loading section 13, as shown in FIG. 15, the organic device is contained in an empty tray (not shown) by a known unloading picker 40 moving up to the rotator section 15. Since the loading part is configured to be adsorbed by the adsorption block 21 and the liquid adhesive is applied to the edges, the unloading picker 40 is simultaneously adsorbed and contained in the inside of the empty tray of the unloading part.

In the present invention configured as described above, when the rotator portion 15 and the positioning portion 29 are arranged in-line on both sides of the frame 11, the rotator portion 15 and the positioning portion 29 are absorbed by the rotator portion 15 on one side. In the process of applying the liquid adhesive to the edge of the organic device 1 by the liquid adhesive application part 33, the organic device can be loaded or unloaded on the rotator part 15 on the other side, and thus the cycle time of expensive equipment ( cycle-time) can be minimized.

When the rotator portion 15 and the positioning portion 29 are arranged inline on both sides of the frame 11 in this way, the coating means cleaning portion (shown in FIG. 6 between the rotator portions 15) is shown. In addition, the automatic cleaning of the outlet of the application means 37 in a state in which the operation of the device is temporarily stopped according to the set value (for example, one lot) further minimizes the application failure of the liquid adhesive. It is preferable because it can be done.

In one embodiment of the present invention, the coating means cleaning unit 42 is provided with a tank 36 in which the cleaner 35 is contained, and immersed in the cleaner in the tank, and having a detergent accommodating space therein ( A cylinder 38 having a 38a, a piston 39 elastically installed in the receiving space and having a passage 39a for a cleaning agent therein, a cleaner 55 provided at the tip of the piston, The passage 39a of the piston 39 and the balls 41a and 41b which open and close the passage of the cylinder 39 are comprised.

At this time, if a nozzle 46 for injecting air pressure is provided on one side of the cleaning part 42, the cleaning agent remaining in the outlet of the coating means can be quickly removed after cleaning the application means 37 by the cleaning agent. Has an advantage.

In one type of the rotator portion 15 and the positioning portion 29, the coating means cleaning portion 42 may be provided on either side.

The method of automatically applying the liquid adhesive along the side edge of the organic device 1 by using the equipment of the present invention configured as described above will be described in more detail.

FIG. 18 is a flow chart for explaining the application method of the present invention, in which the organic element 1 to be sealed by applying a liquid adhesive to the edge is inserted into the recess 12a of the tray 12 shown in FIG. Inserted in turn and then loading it in the loading position (loading position) of the loading unit 13 (S100).

In an embodiment of the present invention, a tray filled with the organic device 1 in a state where the loading plate 49 on which the tray 12 is placed is kept in a horizontal state as shown in FIG. 4 so as to minimize the size of equipment. (12) is placed on the loading plate 49, and then the cylinder 47 is operated to rotate the loading plate 49 on which the tray is placed in the vertical direction to rotate the organic plate 1 inserted into the tray 12. At this time, the glass cover 3 is directed downward so that the glass cover 3 is adsorbed by the loading picker 14, and the glass substrate 2 adsorbed by the adsorption block 21 has an upper portion. The organic element 1 is fitted to the tray 12 so as to face the same.

As described above, when the start button (not shown) is pressed in a state in which the tray 12 into which the organic device 1 is inserted is placed in the vertical state to the loading unit 13, a plurality of holding means 14a maintain the vertical state. The holding means 14a is held horizontally by the cylinder 14b as shown in FIG. 7A in the process of the known loading picker 14 having the X-Y robot 43 moves to the loading unit 13 by the X-Y robot 43. (S200)

Thereafter, when the loading picker 14 enters the tray 12 side located in the loading unit 13 as shown in FIG. 7B, each holding means 14a is positioned directly below the organic device 1, In this state, while the holding means 14a of the loading picker 14 is connected to the glass cover 3 of the organic element 1 while forming a vacuum pressure (a point where the organic element is located between the recessed grooves) After raising, the loading picker 14 is retracted from the tray 12 as shown in FIG. 7C and the plurality of organic elements 1 are separated from the tray 12 by the plurality of holding means 14a.

After the holding means 14a of the loading picker 14 sucks and extracts the plurality of organic elements 1 from the tray 12 in the above-described operation, the holding means having the organic elements 1 adsorbed as shown in FIG. 7D ( 14a) is reduced to an initial state by the re-drive of the cylinder 14b, so that the organic element 1 adsorbed and suspended by the adsorption means 14a is maintained in a vertical state (S300).

Thereafter, when the loading picker 14 reaches the adsorption block 21 of the rotator section 15 while drawing the locus in the direction of the arrow shown in FIG. 7E by driving the rodless cylinder 53, the loading picker 14 When the rodless cylinder 53 is re-driven, the organic element 1 is lowered to the adsorption position. At this time, the holding means 14a on which the organic element 1 is adsorbed does not interfere with the adsorption block 21 of the rotator unit 15. The organic element 1 does not collide with the adsorption block 21 because it is not positioned.

In this state, when the loading picker 14 moves finely toward the adsorption block 21, when the organic element 1 is connected to the adsorption surface, the vacuum is released from the holding means 14a. The suspended organic device 1 is adsorbed to each of the adsorption blocks 21. At this time, the vacuum forming hole 21a formed in each of the adsorption blocks 21 is subjected to a vacuum pressure, so that the organic device 1 is adsorbed. Adsorbed to block 21. (S400)

After the organic device 1 is adsorbed to the adsorption block 21 in the above-described operation, the loading picker 14 is again plural from the tray 12 located in the loading unit 13 in the same operation as described above. The organic device 1 is held and transferred to the rotator part 15 located on the other side.

At this time, if the glass substrate 2 of the organic element 1 is adsorbed to the adsorption block 21 in a vertical state and the positions thereof are aligned, the position of the organic element 1 does not have to be re-determined. Since the plurality of organic elements 1 contained in the tray 12 are adsorbed and loaded by 14, the position of the organic elements 1 must be re-determined.

That is, as the holding means 14a of the loading picker 14 vacuum suction the plurality of organic elements 1 from the recessed grooves 12a of the tray 12 having a tolerance, and transport them to the adsorption block 21, respectively. Since the position of the organic device 1 is different, it must be re-determined.

Therefore, the adsorption pressure acting as the vacuum forming hole 21a is about 1.5kg / cm 2 so that the position can be moved finely without being separated from the adsorption block 21 when positioning the organic device 1, and then the servomotor 31 Is driven to move the pair of positioning blocks 30 suspended from the timing belts 50 and 52 simultaneously in the direction of the arrow shown in FIG. 13A. As shown in FIG. 13B, the position in the Y-axis direction is rearranged by the vertical guide surface 30a of the positioning block 30.

After the positions in the Y-axis direction of the organic elements 1 adsorbed to the respective adsorption blocks 21 are rearranged by the above operation, the two positions are disposed so that the vertical guide surface 30a is finely spaced from the organic elements 1. After moving the crystal block 30 to both sides, the elevating plate 18 is driven by the elevating and lowering means 24 so that the upper surface of the organic element 1 is connected to the rod 32 fixed to the horizontal guide surface 30b. When slightly raised, the upper surface of the organic element 1 is connected to the rod 32 fixed to the horizontal guide surface 30b, so that positioning in the X-axis direction is completed.

After re-determining the position of the organic device 1 adsorbed on the adsorption block 21 by the movement of the positioning block 30, it maintains the adsorption pressure that was applied to about 1.5kg / cm2 and 5-6kg / cm2. At the same time, since the positioning block 30 is reduced to the initial position, the position of the organic device is not changed in the process of applying the liquid adhesive along the edge of the organic device 1 (S500).

At this time, the uppermost surface of the organic device 1 is in a state where it is placed in the application position 25 as shown in Fig. 14A.

When the position of the organic device 1 is rearranged and the X-Y robot 34 is driven while the top surface is positioned at the application position 25, the application means 37 is moved toward the rotator portion 15. The application means 37 is close to the upper surface of the organic element 1 adsorbed on the adsorption block 21 (applicable nozzle is about 0.2mm, the jetting valve is about 1-2mm), in this state the application means 37 Since the liquid adhesive is applied while moving along the application direction of the organic device 1 adsorbed to the adsorption block 21, the liquid adhesive is applied to the top surface of the organic device 1 (S600).

After the liquid adhesive is applied to the top surface of the organic device 1 in the same manner as described above, the lifting plate 18 is disposed so that the organic device 1 adsorbed on the adsorption block 21 does not interfere with the application means 37. As shown in FIG. 14B, the adsorption block base 20 provided with the adsorption block 21 is rotated by 90 ° as shown in FIG. 14C while descending as shown in FIG. 14B and driven by the motor 23. (S700)

As described above, after any one side of the liquid adhesive is applied in the horizontal direction, the elevating plate 18 is driven to the application position 25 of the organic device 1 by the driving of the elevating and lowering means 24 as shown in FIG. 14D. This raises the, the lifting plate 18 is raised while maintaining the horizontal state by the guide portion (17).

In this case, the position where the elevating plate 18 rises is higher than the application point of the upper surface of the organic element 1.

This is because the application position 25 on which the liquid adhesive is applied is constant, whereas the organic device 1 having a high height and a narrow width is adsorbed to the adsorption block 21 in the initial vertical state.

After one side of the organic element 1 adsorbed on the adsorption block 21 reaches the application position 25 by raising the lifting plate 18, the application means 37 is applied to the organic element (by the same method as described above). The liquid adhesive is applied while moving horizontally along the side of 1). At this time, the driving circuit portion is formed on the glass substrate 2 on one side, so that the liquid adhesive cannot be applied. The liquid adhesive is applied while delaying the movement of the application means 37 so as to flow into the adhesive surface by the capillary phenomenon.

After the liquid adhesive is applied to one side of the organic device 1, the adsorption block 21 is adsorbed to the adsorption block 21 when the adsorption block base 20 is rotated 180 ° by the driving of the rotator unit 15 by the above-described operation. The lifting plate 18 is lowered in the state as shown in FIG. 14C by the lifting and lowering means 24 so that the organic device 1 does not interfere with the application means 37 and the motor 23 is driven. Since the adsorption block base 20 is rotated 180 °, the other side of the organic device 1 positioned on the opposite side is maintained in a horizontal state. (S900)

Then, after the other side of the organic element 1 adsorbed on the adsorption block 21 reaches the application position 25 by raising the lifting plate 18, the application means 37 is applied by the same method described above. The liquid adhesive is applied while moving horizontally along the side of the organic device 1 (S1000).

After the liquid adhesive is applied along the edge of the organic element 1 adsorbed on the adsorption block 21, the liquid adhesive coating part 33 is reduced to the initial position by the X-Y robot 34 and unloaded at the same time. The unloading picker 40 positioned at the portion moves to the upper portion of the rotator portion 15 where the adsorption block 21 is positioned by the X-Y robot 45 to simultaneously apply the organic element 1 coated with the liquid adhesive. Hold and move to draw the same trajectory as the arrow of FIG. 15 to unload into the empty tray located in the unloading part, wherein the holding means 40a of the unloading picker 40 is adsorbed to the adsorption block 21. At the moment of holding the organic element 1, a vacuum pressure is applied to the holding means 40a and the vacuum pressure applied to the adsorption block 21 is released, so that the organic element 1 can be unloaded. (S1100)

As described above, the organic device 1 is adsorbed on the adsorption block 21 to apply a liquid adhesive. After the liquid adhesive is applied, the unloading picker 40 separates the organic device adsorbed on the adsorption block 21. In the transfer process, a coating layer 21b of diamond, teflon, perylene, etc. is formed on the surface of the adsorption block 21 on which the glass substrate 2 of the organic device 1 is adsorbed and has excellent lubricity. At the same time, the adsorption surface of the block 21 is prevented from being worn, and at the same time, particles are prevented from being worn.

If the loading unit 13 and the loading picker 14 and the unloading picker 40 and the unloading unit is composed of only one and the rotator unit 15 and the positioning unit 29 are configured side by side in-line (in-line) While the loading picker 14 loads the organic device 1 from the tray 12 of the loading unit 13 to one of the rotator units 15, the rotator unit located on the other side is coated with a liquid adhesive. When applying an organic device loaded on one rotator part, the unloading picker 40 of the unloading part holds and unloads the organic device already coated with liquid adhesive, thereby maximizing the operation rate of expensive equipment.

On the other hand, the liquid adhesive is sprayed when water droplets are formed due to the vaporization of the liquid adhesive in the ejection hole (not shown) of the application means 37 as the continuous operation of applying the liquid adhesive of the organic device (1) Since it is more preferable to go through a cleaning step for periodically cleaning the application means 37, such cleaning may be performed manually by an operator, but is set in a controller (not shown) to realize the automation of equipment. It is more preferable to periodically perform the operation in a state where the operation of the device is temporarily stopped according to the set value.

This cleaning step is possible by spraying the cleaning agent toward the application means 37 and cleaning the air after the application means 37 reaches the cleaning position while the operation of the equipment is temporarily stopped.

That is, after the application means 37 reaches the upper portion of the cleaner 55 of the cleaning part 42, the cylinder 54 is driven to raise the tank 36, so that the piston 55 fixed with the cleaner 55 is fixed. ) Is lowered while compressing the spring 56, while the passage of the cylinder 38 has the ball 41b closed, so that a certain amount of the cleaner 35 in the accommodation space 38a closes the outlet of the passage 39a. The application means 37 is cleaned because the ball 41a is pushed up and supplied to the cleaner 55.

After cleaning the coating means 37 in the above-described operation, the compressed air is sprayed through the nozzle 46 while the coating means is moved to one side to remove the cleaning agent remaining at the inlet through which the liquid adhesive is discharged. The adhesive can be applied stably along the edge of the organic device (1).

As described above, the loading picker 14 holds the loading picker 14 once from the tray 12 located in the loading section 13 and transfers it to the rotator section 15 to which the liquid adhesive is applied. After the conversion, the application means 37 moves horizontally along the edge of the organic device, and after the operation of applying the liquid adhesive is completed, the unloading picker 40 describes one cycle of unloading into the empty tray of the unloading part. In this case, it is understood that the tray may be repeatedly replaced by repeatedly replacing the tray so that the organic device is positioned in the loading unit or by loading the tray filled with the organic device by a separate automation facility.
