Work stage system for flat-panel displays and the use of this system, which saves loading and unloading time, thereby increasing the work efficiency of the LCD which the workbench handles per reference time, and increasing productivity. It relates to a flat display working method.

The so-called flat panel display (FPD) refers to a flat panel display as a whole, and is categorized into a cathode ray tube (CRT) display and a liquid crystal display (LCD) to be described later.

The CRT is made of glass and panels joined together in front and rear, and the electron gun is accommodated inside the neck portion of the funnel, which has a high resolution but a heavy weight. Accordingly, as the display industry develops in recent years, the supply and demand of LCDs rather than CRTs are increasing. Hereinafter, for convenience of description, the flat panel display will be described as LCD.

1 is a schematic plan view of a work stage system for a conventional planar display, and FIG. 2 is a side view of FIG. As shown in these figures, a conventional work stage system for a flat panel display has a work table 116 in which the LCD 101 of a work object is largely arranged, and is mounted on the work table 116 and mounted on the work table 116. It includes a working unit 120 for performing a predetermined operation toward the LCD 101 loaded in the). One side of the work table 116 is provided with a robot 117 that moves in one direction to move or unload the LCD 101 to the work table 116.

A plurality of support pins 119 supporting the lower surface of the LCD 101 are provided on the work table 116. When the LCD 101 is moved to the worktable 116 by the robot 117, the support pins 119 stand up to support the lower surface of the LCD 101 as an end thereof, and one direction when the robot 117 is taken out. By rotating the LCD 101 to face the top of the work table (116).

On the upper side of the worktable 116, a pair of columns 118a spaced apart from each other at predetermined intervals is mounted, and a connection portion 118b interconnecting the columns 118a between the pair of columns 118a. Is provided. The working unit 120 is provided in the connecting portion 118b to perform a predetermined operation toward the LCD 101 while moving along the connecting portion 118b by a predetermined electrical signal.

Here, the predetermined operation toward the LCD 101, as will be described later in detail, in addition to the inspection of the short circuit and disconnection of the electrical signal that can be formed in the LCD 101, repairing it, etching, such as repairing, etc. ) Includes all operations, inspections, and repairs performed before the product is released as a good product, which will be described later.

Looking at the operation mechanism for a conventional work stage system for a flat display having such a configuration is as follows.

First, the robot 117 grips one LCD 101 from a cassette (not shown) in which the LCD 101 of the work object is gathered, and then arranges the LCD 101 above the work table 116. When the LCD 101 is disposed above the work table 116 by the robot 117, the respective support pins 119 rotate so that their ends face upward.

When the support pins 119 stand upright, the robot 117 lowers (loads) the held LCD 101 to the ends of the respective support pins 119. Then, it returns to the original position again.

When the LCD 101 is placed at the ends of the standing support pins 119, the support pins 119 rotate in one direction to face the LCD 101 on the work table 116. The position at this time becomes the working position of the LCD 101.

By the way, in such a conventional flat display work stage system, the LCD 101 of the work object is loaded or finished on the work table 116 rather than the actual work time of actually working on the LCD 101. The time taken to unload 101 from worktable 116 is relatively much longer.

Since the time required for loading and unloading the LCD 101 is too long, it is impossible to efficiently perform the operation on the LCD 101, which inevitably lowers work efficiency and significantly reduces productivity. In fact, it is true that the actual amount of work of the LCD 101 which one work table 116 processes per reference time is not so large.

Therefore, if the loading and unloading process of the LCD 101 and the operation for the LCD 101 can be performed in parallel in one work table 116, the work table 116 may be the LCD 101 of the work target. Can save the time taken to load the unloaded LCD 101 from the worktable 116 from the worktable 116, thereby increasing the amount of work of the LCD 101 that the worktable 116 processes per reference time, thereby increasing work efficiency and productivity. This could be greatly improved.

This is because the first and second probe tips 21a and 22a reciprocate only at both end positions of the start position and the end position, so that the control of the lift cylinders 21c and 22c is advantageous compared to the motor control described above.

The operation of the LCD inspection apparatus having such a configuration will be described with reference to the stage system for a flat panel display described above.

First, the robot 17 grasps one LCD 1 from the cassette in which the LCDs 1 of the work object are gathered, and then arranges the upper side corresponding to the first work table 16a . When the LCD 1 is disposed upward by the robot 17 corresponding to the first work bench 16a , the first support pin groups 19a are rotated so that their ends face upward.

When the first support pin groups 19a are standing upright, the robot 17 lowers the held LCD 1 to the ends of the first support pin groups 19a. When the LCD 1 is placed at the ends of the standing first group of support pins 19a, the first group of support pins 19a rotate in one direction to move the LCD 1 to the upper first work position of the work table 16 ( Face to 16a).

When the LCD 1 is placed on the first work bench 16a by the robot 17 and the first support pin groups 19a, the meter reading means 20 which has received the electrical signal by the controller 18 is transferred to the moving means . The predetermined work is performed toward the LCD 1 while being moved to a predetermined position by the.

That is, the four X-axis rail blocks 43 are moved on the first and second X-axis rail portions 42a and 42b in the X-axis direction by the X-axis driving portion 44, and the Y-axis driving portion 54 The four Y-axis rail blocks 53 are moved in the Y-axis direction on the first and second Y-axis rail portions 52a and 52b, respectively.

When the four meter reading means 20 is moved on the plurality of contact pad groups 2a to 2d (see FIG. 6) by the X-axis moving unit 40 and the Y-axis moving unit 50, the Z-axis moving unit ( 60) works. In other words, the movable section 64 moves downward by the Z-axis driving section 66 toward the LCD 1 to be inspected with respect to the binding port 62 .

When it is moved downward to some extent, either one of the first and second probe cards 21 and 22 is lowered by the operation of any one of the first and second probe lifting portions 21b and 22b, and the corresponding probe tip is lowered. Make contact with the contact pad group. When the probe tip is in contact with the contact pad group and detects predetermined information input to the contact pad group, the detected result value is output to the monitor unit 32 to determine whether the LCD 1 to be inspected is good or bad.

On the other hand, as described above, the LCD 1 is placed on the first work bench 16a, and the work is performed by the meter reading means 20, while the robot 17 returns to the original position and returns the new LCD 1 from the cassette. Gripping. And it arrange | positions to the upper side corresponding to the empty 2nd work bench 16b .

When the LCD 1 is disposed upward by the robot 17 corresponding to the second work bench 16b, the second support pin group 19b is rotated at this time, and its end faces upward. When the second support pin groups 19b are standing upright, the robot 17 lowers the held LCD 1 to the ends of the second support pin groups 19b.

When the LCD 1 is placed at the ends of the standing second group of support pins 19b, the second group of support pins 19b rotate in one direction and face the LCD 1 to the top of the second work bench 16b . .

As described above, the time required for loading and unloading the LCD 1 is relatively much longer than the actual working time for the LCD 1 by the meter reading means 20 .

Therefore, in the process of the robot 17 loading the new LCD 1 into the second work bench 16b , the LCD 1 arranged on the first work bench 16a has already finished work by the meter reading means 20. do. As a result, the meter reading means 20 continuously works on the LCD 1 loaded on the second work bench 16b .

On the other hand, the robot 17 moves to the first work bench 16a to take out the LCD 1 on which work is completed on the first work bench 16a . At this time, the first support pin group 19a receiving the signal from the controller 18 stands up again to raise the finished LCD 1 at the first working position 16a. The robot 17 supports the lower end of the LCD 1 injured by the first support pin group 19a and moves it to a separate storage part.

Then, the new LCD 1 is gripped again from the cassette in which the LCDs 1 of the work are gathered, and then loaded onto the first work platform 16a in association with the first support pin groups 19a. Then, during this time, since the meter reading means 20 has completed the work on the LCD 1 loaded on the second work bench 16b , the meter reading means 20 is again controlled by the controller 18 to control the first. The operation of the LCD 1 loaded on the work table 16a is performed.

At the same time, the robot 17 stores the LCD 1 which is completed on the second work bench 16b by the interaction with the second support pin group 19b after being moved to the second work bench 16b. After moving to, the new LCD 1 is loaded again into the second empty work bench 16b .

As described above, according to the third embodiment of the present invention, the loading and unloading process of the loading and unloading of the LCD 1 and the operation of the LCD 1 can be performed in one work table 16. By saving the time, the amount of work of the LCD 1 which processes the work benches 16a and 16b per reference time is increased, which not only increases work efficiency but also significantly improves productivity.

Fourth embodiment

In the fourth embodiment, a description is made without the accompanying drawings. However, since the repair apparatus which has been filed by the present applicant is stolen, those skilled in the art will be able to fully understand and implement the present invention.

For example, if one electrical signal line extending from any one of the contact pad groups 2a to 2d shown in FIG. 6 overlaps with each other and is not parallel to an adjacent signal line (this is referred to as "defect"). The correct image cannot be formed on the LCD. In this case, the defect must be repaired so that the signal lines do not overlap each other by cutting or repairing the overlapping portions between the signal lines. Such equipment is called a repair apparatus.

Therefore, the repair apparatus also has a worktable on which the LCD to be repaired is placed, and a repair apparatus (measurement means) for repairing defects formed on the LCD is mounted on the upper side of the worktable by a separate moving means . . The repair apparatus has a configuration such as a laser scope for repairing while imaging the defect of the LCD mounted on the work table .
