Accordingly, the present invention relates to a paste coating apparatus and a control method thereof, which enable manufacturing of a large quantity of various kinds of flat panel display devices in a faster time by changing the working direction thereof so that the work proceeds.

As is well known, the liquid crystal display (LCD), which is one of the flat panel display devices, has better visibility than the cathode ray tube (CRT), and the plasma display is small because the average power consumption is smaller than that of the screen size CRT. Along with a plasma display panel (PDP) and a field emission display (FED), it has recently been in the spotlight as a next generation display device such as a monitor or a television of a mobile phone or a computer.

The liquid crystal display (LCD) forms a plurality of pixel patterns on one glass mother substrate, a color filter layer on the other opposite mother substrate, and then bonds the two mother substrates to each other. Between the two mother substrates are produced in such a way that the liquid crystal is injected or dropped by a predetermined method.

In the manufacturing process of the above-described flat panel display device, the paste is applied to the mother substrate according to a predetermined substrate pattern by a paste coating device. As shown in FIG. Corresponds to a large mother substrate having a table 1 on which the mother substrate 3 is mounted only in the long axis direction, and a moving means for mounting a plurality of nozzles and allowing the application head including the nozzles to be applied while moving in the S axis. Two columns 2 for discharging the paste, a plurality of nozzles for discharging the paste to form a paste pattern, and a paste pattern can be formed on the mother substrate by relatively moving the mother substrate and the nozzles while discharging the paste. And a pneumatic discharging device for discharging paste, and a relative movement means between the mother substrate and the nozzle. 1) has a structure in which the mother substrate 3 is carried in only the major axis direction as described above.

Referring to the application process of the conventional paste coating apparatus configured as described above is as follows.

First, a predetermined paste pattern is formed on the mother substrate while the mother substrate 3 and the nozzle move relative to each other.

Then, the mother substrate 3 is transferred onto the table 1 by the transfer device so that the mother substrate 3 in the conveying direction is mounted on the table 1 in the long axis direction, and is variable on the table 1 by adsorption pressure. do.

When the adsorption is completed, the two columns 2 are moved to the respective application positions, and the plurality of nozzles mounted on the respective columns also move to the respective application starting positions along the ball screw or the linear motor 4 along the S axis direction of the column. It is moved by the same moving device.

In addition, the two columns and the plurality of nozzles mounted on each column are determined by the data input of the paste pattern to which each coating start position is to be applied in advance, and also the coating height, the coating speed, the discharge pressure, and the number of patterns. Application conditions such as pattern position data and the like are also prepared in advance and inputted.

After the two columns and the plurality of application heads are moved to the initial application position in accordance with the application conditions as described above, each of the application heads are Z-axis (by the set distance between the mother substrate 3 and the nozzle discharge port of the application head) The table 1 on which the mother substrate 3 is mounted, the plurality of nozzles move, or the column on which the nozzle is mounted moves to the mother substrate. By moving relative to the main surface of 3) to form a paste pattern according to the substrate pattern on the mother substrate.

By the way, in the case where the mother substrate 3 can be mounted on the table 1 only in the long axis direction, the coating operation using the paste coating apparatus according to the large quantity and the various kinds on the large mother substrate is as follows.

That is, as shown in Fig. 2, in the case of the pattern A to obtain four large substrates A and six small substrates B as an example, in the case where the operation is performed in the long axis direction, (1) → (2) → (3) → (4) → (5) → (6) → (7) → (8), on the other hand, when work is performed in the short axis direction in the same A pattern 3, the operation proceeds from (1) to (2) to (3) to (4) to (5).

That is, when comparing the two cases, when forming a paste pattern such as the A pattern, working in the short axis direction can reduce the number of working processes three times than when working in the long axis direction.

However, as described above, in the case of the conventional paste coating apparatus, the mother substrate can be mounted only in the long axis direction, and accordingly, the paste coating process is controlled to be performed. Work process and time-consuming problems arise.

In addition, coating conditions such as coating height, coating speed, discharge pressure, pattern number, pattern position data, and the like are also prepared in advance and inputted to the controller.

Meanwhile, referring to the paste coating control method using the paste coating apparatus for a flat panel display of the present invention configured as described above, as shown in FIG. 8, preparing a mother substrate 3 on which a substrate pattern is formed. (S1); Mounting the mother substrate (3) (S2); Identifying a substrate pattern of the seated mother substrate (3) and measuring a long axis working time and a short axis working time, respectively (S3); Comparing the measured long axis working time with the short working time to determine that a minimum working time is achieved (S4); Changing the position of the mother substrate (3) in a direction in which the minimum working time is made (S5) (S6); In addition, a method of controlling a paste coating apparatus for a flat panel display device, comprising the step S7 of starting a paste coating operation, is provided.

That is, first, a mother substrate 3 having an arbitrary substrate pattern is prepared (S1), and the mother substrate is seated on the stage 50 positioned on the table 40 (S2).

Then, the substrate pattern of the seated mother substrate is identified, and the time taken for the paste application in the major axis direction and the time taken for the paste application in the short axis direction are respectively measured (S3).

Here, the step of identifying the pattern of the seated substrate means to grasp the state, such as the quantity, size, type and arrangement of the plurality of flat panel display substrates to be produced on the mother substrate 3, generally One end of the mother substrate is provided with a barcode indicating the quantity, size, arrangement, etc. of the substrate for a flat panel display device to be manufactured, and consists of a process of identifying the barcode when the mother substrate is brought in.

On the basis of the substrate pattern of the mother substrate 3 thus identified, this time, it is faster to work the mother substrate in either of the long axis direction or the short axis direction. The process of determining whether the coating operation can be carried out by comparing each step (S4).

After doing this, the step S5 and S6 of changing the position of the mother substrate 3 in the working direction in which a faster working time determined during the long axis work and the short axis work occurs.

That is, for example, when the mother substrate 3 is loaded in the long axis direction, working in the long axis direction in the step of comparing the long axis work time and the short axis work time with each other is more time intensive than working in the short axis direction. If it is small, the paste coating operation proceeds as it is, and if the mother substrate 3 is loaded in the short axis direction, the controller of the coating apparatus sends a signal to the motor 70 so that the motor 70 is The table 40 is rotated by ± 90 ° or ± 270 ° so that the paste coating operation is performed in the short axis direction.

After that, the step of starting the paste coating operation is carried out (S7).

In the following, in order to understand and explain the operation of the paste coating operation of the present invention in more detail, the time required for each paste coating operation in the long axis or short axis direction in each pattern taking two patterns, A pattern and B pattern as an example. Compare and compare with.

First, as shown in Fig. 2, in the case where the work is performed in the long axis direction in the A pattern to obtain four large substrates A and six small substrates B, the application procedure is (1) to (2). → (3) → (4) → (5) → (6) → (7) → (8).

On the contrary, as shown in Fig. 3, when the work is performed in the short-axis direction in the A pattern, the work order proceeds from (1) → (2) → (3) → (4) → (5).

Here, forming time of the paste pattern using two heads H1 and H2 assuming that the coating speed is 100 mm / sec, the length of the large substrate A is 3800 mm, and the length of the small substrate B is 1400 mm. When compared and explained, it becomes as follows.

That is, as shown in the figure, when the work order (1) → (2) → (3) → (4) → (5) → (6) → (7) → (8), As a result, since the large substrate A has to work twice and the small substrate B has to go through six times, it takes (38sec * 2 times) + (14sec * 6 times) = 160sec.

In the same way, when the work order (1) → (2) → (3) → (4) → (5), the working time is determined and the large substrate A performs two operations, and the small substrate ( B) has to work three times, so it takes (38sec * 2 times) + (14sec * 3 times) = 118sec.

In other words, when comparing the two operations, the mother substrate is brought into the table in the short axis direction having the work order of (1) → (2) → (3) → (4) → (5) in the long axis direction. This will increase your productivity by 45% or more, compared to working with a mother board.

On the other hand, using two coating heads (H1, H2), assuming that the coating speed is equal to 100mm / sec, a large pattern 2400mm, a small pattern 1200mm, the large shown in Figures 4 and 5 attached Comparing the case of the B pattern for obtaining eight substrates A 'and six small substrates B', the following is as follows.

As shown in FIG. 4, when the operation time taken in the long axis direction is taken, the large substrate A 'needs to be worked four times and the small substrate B' needs to be done three times, thus (24sec * 4 times). ) + (12sec * 3 times) = 132sec, and in the same manner, as shown in FIG. Since the small substrate B 'has to be worked six times, it takes (24sec * 4 times) + (12sec * 6 times) = 168sec.

Therefore, in the case of the B pattern, the case where the mother substrate is carried in the major axis direction can be more than 35% higher than the case where the mother substrate is carried in the minor axis direction.

That is, as described in the above two examples, since the paste pattern forming time varies greatly according to the paste pattern, the table having the mother substrate loaded according to the pattern is rotated according to each situation so that the minimum working time can be achieved. By doing so, it is possible to improve the productivity of tens of percent.
