It can be done (S132).

In addition, the control unit 300 determines the state of the sealing line SL detected by the sealing line state detection unit 240 when the resin dispenser 230 discharges the sealing resin R to form the sealing line SL. Accordingly, at least one of the moving speed of the resin dispenser 230 , the discharge amount of the resin dispenser 230 , the discharge pressure of the resin dispenser 230 , and the heating temperature of the sealing resin R may be controlled ( S133 ).

That is, the control unit 300 obtains the shape of the sealing line SL photographed in real time from the sealing line state detection unit 240 which is a vision camera, and then compares the thickness of the sealing line SL with a predetermined reference value and discharges it. After determining the state, the driving of the dispenser driving unit 250 is controlled to control the moving speed of the resin dispenser 230 , or the syringe 231 of the resin dispenser 230 is controlled to control the amount and discharge of the resin (R) for sealing.

Then, the control unit 300 calculates at least one position value spaced apart from the end of the sealing line SL according to the state of the end of the sealing line SL ( S142 ), and then at the end of the sealing line SL and at least A speed value and a delay value between each of one position value may be calculated (S143).

Finally, the controller 300 may sequentially move the resin dispenser 230 along each of the at least one position value using the speed value and the delay value between each of the at least one position value ( S144 ).

12 is a diagram illustrating an example in which a dispensing unit constituting a dispensing apparatus for manufacturing a display panel according to an embodiment of the present invention moves in a second section.

For example, as shown in (a) of FIG. 12 , the control unit 300 in advance from the end P1 of the sealing line SL for the second section II according to the state of the end P1 of the sealing line SL. One position value P2 spaced apart by a set distance may be calculated. In addition, the control unit 300 controls one speed value between the end P1 of the sealing line SL and the first position value P2, and two delay values at the end P1 and the first position value P2 of the sealing line SL, respectively. can be calculated.

The example shown in (a) of FIG. 12 is suitable for a case in which the sealing resin (R) is agglomerated into a relatively small size at the end of the sealing line (SL).

As another example, as shown in (b) of FIG. 12 , the control unit 300 zigzags from the end P1 of the sealing line SL for the second section II according to the state of the end P1 of the sealing line SL. A plurality of position values (in the example of FIG. 12B , three position values P2 , P3 , and P4 ) may be calculated. And, the control unit 300 is a plurality of speed values between each of the end P1 and the plurality of position values P2, P3, P4 of the sealing line (SL) (in the example of Fig. 12 (b), three speed values) And, it is possible to calculate a plurality of delay values (in the example of FIG. 12B , four delay values) at the end P1 and the plurality of position values P2, P3, and P4 of the sealing line SL.

The example shown in (a) of FIG. 12 is suitable for a case in which the sealing resin (R) is aggregated to a relatively large size at the end of the sealing line (SL). That is, when the control unit 300 calculates a plurality of position values arranged in a zigzag form from the end of the sealing line SL, the syringe tip 231a of the syringe 231 moving from the end of the sealing line SL. Since the formed tail of the sealing resin R can be minimized, it is possible to prevent aggregation of the ends of the sealing line SL.

As such, in the dispensing apparatus 1 for manufacturing a display panel according to an embodiment of the present invention, the dispensing unit 200 is moved to a position spaced apart from the end of the sealing line SL in the second section II. By controlling the movement of 200 , it is possible to solve the problem that the sealing line SL is defective due to the aggregation of the ends of the sealing line SL.

First, an EPU-3522HMB product of EPRI was prepared as a sealing resin (R) for forming a sealing line (SL). At this time, the sealing resin (R) has polyurethane (Polyurethane) as a main component, but has a melting point of 110 to 120 ° C, a viscosity of 2500 ± 500 cps at a temperature of 110 ° C, and 40 minutes at a temperature of 40 to 45 ° C. was cured within

And, set the width, thickness and length of the sealing line (SL) to 1.0mm±0.1mm, 0.3mm±0.1mm, and 6.4mm±0.1mm, respectively, through the initial input value of the control unit 300, and syringe 231 After setting the delay value and the moving speed (linear velocity) at the initial position of 0.5 sec and 8.0 mm/sec, respectively, the resin dispenser 230 and the dispenser driving unit 250 are controlled to control the syringe having a slot-shaped outlet cross section. A sealing line SL was formed by applying a sealing resin R while moving 231 (refer to (b) of FIG. 5 ) (first section (I)).

In addition, after the syringe 231 forms the sealing line SL, the resin dispenser 230 and the dispenser driving unit 250 are controlled to control the end P1(X1, Z1) of the sealing line SL = (6.4mm, 0mm) ) from the three position values P2(X2, Z2) = (X1+1.0mm, Z1+1.0mm), P3(X3, Z3) = (X2-1.0mm, Z2+1.0mm), P4 (X4, Z4) = (X3+1.0mm, Z3-8.0mm), and after setting the delay values in P1 to P4 to 1 sec, control the resin dispenser 230 and the dispenser driving unit 250 to inject the syringe ( 231) was moved (Second Section (II)).

[Comparative Example 1]

As in Example 1, EPRI's EPU-3522HMB product was prepared as a sealing resin (R), and the width, thickness and length of the sealing line (SL) through the initial input value of the control unit 300 were respectively 1.0 mm ± 0.1 mm, 0.3 mm ± 0.1 mm and 6.4 mm ± 0.1 mm were set, and the delay value and movement speed (linear velocity) at the initial position of the syringe 231 were set to 0.5 sec and 8.0 mm/sec, respectively.

Then, by controlling the resin dispenser 230 and the dispenser driving unit 250 to move the syringe 231 having a circular discharge port cross-section, a sealing resin (R) was applied to form a sealing line (SL) (first Section (I)).

In addition, after the syringe 231 forms the sealing line SL, the resin dispenser 230 and the dispenser driving unit 250 are controlled to control the end P1(X1, Z1) of the sealing line SL = (6.4mm, 0mm) ) from one position value P2(X2, Z2) = (X1, Z1+6.0mm) that simply moves the syringe 231 in the upward direction, and after setting the delay value at P1 to 0.5 sec, the resin dispenser ( 230) and the dispenser driving unit 250 to move the syringe 231 (second section (II)).

[Experimental example]

The thickness and shape of the sealing line SL for each of the sealing line SL formed according to [Example 1] and the sealing line SL formed according to [Comparative Example 1] are shown in Table 1 and FIG. 13, respectively. did 13(a) shows the shape of the sealing line SL formed according to [Example 1], and FIG. 13(b) shows the shape of the sealing line SL formed according to [Comparative Example 1], there is.

Thickness of sealing line (SL) (mm) Example 1 0.35 mm (0.3 mm + 0.05 mm) Comparative Example 1 0.65 mm (0.3 mm + 0.35 mm)

First, referring to [Table 1], the thickness of the sealing line SL formed in the first section (I) by [Example 1] is the sealing line formed in the first section (I) by [Comparative Example 1] When compared with the thickness of (SL), it can be confirmed that the required value of the preset thickness of 0.3 mm ± 0.1 mm is satisfied.

In addition, referring to FIG. 13 , it can be confirmed that the end of the sealing line SL formed by [Example 1] is in a state almost similar to the thickness of the entire sealing line SL without the sealing resin R being agglomerated, It can be seen that the end of the sealing line SL formed by [Comparative Example 1] is in a state in which the sealing resin R is agglomerated.

In conclusion, when the sealing line SL formed by [Example 1] is compared with the sealing line SL formed by [Comparative Example 1], the sealing line SL formed on the side surface of the display panel 10 is In addition to being able to form a thinner width or thickness, the sealing line SL can be uniformly formed as a whole by minimizing aggregation of the ends of the sealing line SL.
