Description

WORK TABLE FOR FLAT DISPLAY PANEL TESTER}

The present invention relates to a work table provided in the flat panel display panel inspection apparatus, and more particularly, when fixing the panel of the flat panel display panel to be inspected, there is no need to replace a separate fixing block, etc. The present invention relates to a worktable for a flat panel display panel inspection device which can be smoothly fixed without interference and also prevents interference with peripheral units due to up, down, left, and right movement.

In general, a flat panel display panel is a display device that replaces a conventional cathode ray tube (CRT), a liquid crystal display device (LCD), a plasma display panel (PDP), an organic Organic light emitting diodes (OLEDs) and the like are typically used, and their applications are widely applied to display panels of TVs, computers, monitors, notebooks, and various industrial devices.

The importance of such a flat panel display panel is further emphasized, and in particular, low power consumption, thinness, light weight, high quality, and portability are on the rise.

Meanwhile, in the process of producing the flat panel display panel, an inspection process for inspecting the appearance and electrical defects of the panel is performed before assembling the backlight and the driving circuit, and the inspection process is provided in each unit panel in the inspection apparatus. Each line and gate are inspected for disconnection, color, and visual inspection using a microscope.

Thus, in the process of performing the inspection process, a known inspection apparatus includes a probe unit including a database and a gate base for applying power to a data line and a gate line of a panel, and after setting a panel transferred from a carrier, the probe unit A work table is provided as a fixing means for advancing to the side to fix the panel.

Conventional work table provided in the inspection apparatus as described above, by fixing the supplied panel by a vacuum, it is usually composed of a fixed block that can be vacuum suction on the base plate.

However, in the case of the conventional work table, since the fixed blocks of the work table are standardized, in order to fix panels classified into various types, work tables of various shapes and sizes corresponding to the various types of panels are manufactured. By doing so, there is a big problem in economic losses as a large production cost is required.

In order to solve such a problem, various types of work tables have been proposed and used in the related art. As shown in FIGS. 4A and 4B, the work table 100 is a guide installed up and down on the base plate 110. Each up and down symmetrically on each of the movable blocks 120a, 120b, 120c and 120d, which are conveyed up and down by a conveying screw rotated by respective driving sources, which are upper and lower conveying means on the rail. The left and right fixing blocks 130a, 130b, 130c and 130d are mounted, and the upper, lower, left and right fixing blocks are connected to respective driving sources, a transfer screw and a belt, and left and right transferred. It consists of right conveying means.

In the above, the upper, lower, left, right fixing block is formed with a suction hole that can adsorb the bottom of the panel.

Accordingly, in the case of the work table, the fixed block moves up, down, left, and right in the direction facing each other to the movable block and the left and right transport means, and the fixed block is moved forward, backward, and left on the same center line. By moving it to the right, it was possible to fix panels of various sizes.

However, in the case of such a conventional work table, there was an advantage that can be fixed to all four sides of the panel to be fixed, but the upper and lower fixing blocks of the probe unit provided around the work table in the process of moving correspondingly Due to the problem of collision as in the circular arc according to the height, the distance between the fixed blocks is very limited according to the panel to be fixed on the work table, and thus the panel to be inspected is also very limited. There was this.

Due to the above problems, the work table 100 as shown in FIGS. 5A and 5B is used in the related art, and the upper fixing block 130a and the left and right fixing blocks 130c and 130d except for the lower part are used. The panel is fixed by the left and right fixing blocks 130c and 130d which are transported up and down as well as being transported up and down by the known driving source and the transfer means. This method is also used, but this is not only a problem that can not be used in the case of the panel to be fixed at the bottom of the left and right fixing block together with the upper fixing block in the other unit and the circular arc around the work table in the process of transferring the lower A conflicting problem occurred as follows.

In addition, as described in the Republic of Korea Patent Registration No. 10-0820049 "Inspection stage of the liquid crystal display panel inspection equipment" is registered a structure that can be fixed up, down, left, right regardless of the size of the panel. The first adjusting member for adjusting the work table for fixing the horizontal direction, the second adjusting member for moving in the longitudinal direction, and the vertical side detachable from the first adjusting member and supporting the vertical side of the panel, respectively It includes a fixed bar and the horizontal side fixing bars that are removable from the second control member and supporting the horizontal side of the panel, respectively, according to the size of the panel as described above removable from each of the first and second adjusting member There was a fairly cumbersome and inconvenient problem of having to replace the fixing bars.

In addition, by separately providing the first and second adjustment members, there is a problem inevitably have a more complicated structure.

The present invention has been made to solve the above-mentioned conventional problems, the main object of which does not need to replace a separate fixing block when fixing the panel of the flat panel display to be inspected, as well as the size and orientation The present invention provides a work table for a flat panel display panel inspection device which can be easily fixed without causing interference with peripheral units due to up, down, left, and right transfer.

Another object of the present invention is to fix the small size panel to also be smoothly fixed in the upper or lower and left and right.

Still another object of the present invention is to allow a small panel to be tightly fixed.

Referring to the attached process of the present invention configured as described above with reference to Figures 3a to 3d in more detail as follows.

First, the upper and lower fixed blocks and the left and right fixed blocks are aligned by using the upper and lower power transmission means and the left and right power transmission means before the relatively large panel is supplied for inspection.

Then, when fixing the upper part of the panel according to the size or type or specification of the supplied panel, the upper and lower power source (M1) and the upper, lower, so that the upper end of the panel can be fixed by the upper fixing block 10 as shown in Figure 3a The lower and lower fixed blocks 10 and 10A are lowered by the lower power transmission means 11, transferred to the correct positions for the inspection, and the inspection is performed by a known method.

In addition, when fixing the lower part of the panel, the upper and lower power source M1 and the upper and lower power transmission means 11 so that the lower end of the panel can be fixed by the lower fixing block 10A as shown in Figure 3b. After raising the lower fixed block 10 (10A) and transporting it to the correct position for inspection, the inspection is performed by a known method.

At this time, when fixing the upper or lower portion of the panel, the left and right fixing blocks 20 and 20A are disposed between the upper and lower fixing blocks by respective left and right power sources and left and right power transmission means to suit the size of the panel. Transfer to left and right side to fix both sides of panel.

In addition, the upper and lower fixed blocks 10 and 10A are in parallel positions facing each other, and the left and right fixed blocks 20 and 20A are transported to the left and right between the upper and lower fixed blocks. In other words, as each fixing block is moved up, down, left, and right while maintaining a rectangular shape to fix the panel, other units according to the panel fixing, particularly probe units provided around the work table, are not interfered with. Not only can the transfer be carried out smoothly, but also because of the condition that the fixing work can be done immediately without replacing a separate fixing block in the process of fixing the upper or lower part according to the type or specification of the object to be inspected. In addition to having a condition that can be inspected, other sizes of panels also have a condition that can be inspected immediately.

Thus, in the manner of fixing the top or bottom, as well as the panel of various sizes, it is possible to selectively be fixed, as well as to allow each fixed block to be transported within a certain range, regardless of the size of the panel In addition, the fixing is made regardless of the upper and lower fixing method can be made more quickly and smoothly inspection.

On the other hand, when you want to fix the small panel, when you want to fix the upper or lower as shown in Figure 3c and 3d, as described above, the lower and lower fixing blocks 10, 10A After moving the left and right fixing blocks 20, 20A to suit the size of the panel to be fixed at the same time, the support means 30 provided between the left and right fixing blocks 20, 20A are also transferred and fixed. Support the bottom of the panel to support it.

In other words, when the upper and lower fixed blocks 10 and 10A are transferred upward or downward by the upper and lower power sources and the power transmission means, the support plate serving as the support member by the auxiliary power source and the power transmission means, which is the support means 30, is provided. (34) It may also be transported to the top or bottom so that it can be positioned on the top or bottom of the panel.

Then, when the left and right fixing blocks 20 and 20A are conveyed to fix both sides of the panel, the supporting block 35 provided on the inner side thereof also moves to the inner side so as to face each other with the guide rail R3. The upper and lower fixing blocks and the left and right fixing blocks are supported by the bottom of the panel while being transported from the top.

At this time, at least one adsorption hole is formed on the upper surface of the support block so that a well-known vacuum adsorption can be made, and thus the panel may be tightly and tightly fixed when the panel is fixed.

Accordingly, even when the size of the panel is relatively small, as well as selectively fixing the top or bottom of the support means can be made more stable and easily fixed.

Therefore, the small sized panel also has an excellent condition that can be fixed stably by the support means as well as to selectively fix the top or bottom without replacing a separate fixing block.
