Reference numeral 500 denotes a tray lifting means, which raises the tray 20 so that the liquid crystal panel 10 can be taken out or the empty tray can be taken out from a single tray 20 separated by the tray separating means 200. Or means for descending.

That is, as shown in detail in FIG. 7, the tray lifting means 500 moves up and down along the vertical guide member 510 and the vertical guide member 510 which is pivoted to vertically lift the tray 20. And a lifting member 520 coupled by a ball screw 522, and a motor 530 generating a driving force for rotating the vertical guide member 510.

Here, the shaft of the motor 530 and the shaft of the vertical guide 510 are connected to the belt by pulleys 532 and 512, respectively, to transmit power.

Looking at the operation of the input and take-out device of the liquid crystal panel according to the present invention provided as described above are as follows.

The trays 20 containing the liquid crystal panel 10 one by one are stacked in 24 stages, and the trays 20 are loaded into the upper frame 110 of the feeder 100.

At this time, the transfer table 100 is to be stopped by the brake motor 160, not a separate stopper.

The tray 20 of the 24-stage transfers only the lowest tray 20 to the next process by the tray separation means 200, and raises the remaining tray 20 of the 23 stages.

At this time, the stop action of the tray is made by the stopper 210, the locking member 222, 224 to the jaw portion of the tray 20 in accordance with the action of the cylinder member 232, 234 in the horizontal direction It is in close contact with each other and is lifted by the cylinder members 242 and 244 in the vertical direction.

When the tray 20 of the 23 stages is sensed by the photosensors 260 on both sides, the lower tray 20 is transferred again.

After the tray 20 of the first stage is transferred, the tray of the 23 stage is lowered back to the original position.

This operation is repeated until the 24 trays are used up.

Thereafter, the liquid crystal panel 10 determines the position for positioning the correct process by the positioning means 400.

At this time, the liquid crystal panel 10 is absorbed and raised by the plurality of vacuum pads 342 and 344 mounted at the tip of the Z-axis robot 330.

The liquid crystal panel 10 thus raised is unloaded on the seating plates 402 and 404 of the positioning means 400, and at the same time, the X and Y are positioned by the positioning vacuum pad 346 of the Z-axis robot 330. Direction to determine the exact position of the liquid crystal panel 10.

When the positioning is completed, the liquid crystal panel 10 is again adsorbed by the other vacuum pads 342 and 344 of the Z-axis robot 330, and then is mounted on the fixed pallet 30 to wait for the process.

Thereafter, the liquid crystal panel 10 is moved to the curing machine 600 or the dispenser 700 to perform a corresponding work process.

On the other hand, when the liquid crystal panel 10 is raised from the tray 20 by the robot, the empty tray is lowered toward the lower frame 120 and taken out in the direction opposite to the advancing (input) direction.

When the empty tray 20 thus extracted reaches the tray separating means 200 side, the cylinder members 232 and 234 in the horizontal direction move forward to hold the tray 1 by the locking members 222 and 224. When the empty tray 20 is supplied in this state, the held tray is placed again.

This operation is repeated until the tray of 24 stages is loaded.

As a result, after the empty tray 20 has been loaded with all 24 stages, the empty tray 20 is taken out on the conveyer of the lower frame 120.

The operation process described above relates to a loading process of injecting the liquid crystal panel 10 from the tray 20 into the fixed pallet 30, and recovers the liquid crystal panel 10 of the pallet 30 to the tray 20. The unloading process is the same as the above-described operation.

According to the present invention described above, the liquid crystal display panel put into a predetermined process operation can be automatically not only positioned but also put and taken out, so that the productivity can be further improved.
