The present invention relates to an apparatus for inspecting a flat panel display panel, and more particularly, to a flat panel display panel inspecting apparatus for inspecting the appearance and electrical defects of each unit panel by applying power to a data line and a gate line of the panel. will be.

In general, flat panel displays are the next-generation display devices developed to replace Cathode Ray Tubes (CRTs), which are used in TVs and computer monitors.These include Liquid Crystal Display Device (LCD), Plasma Display Panel (PDP) and EL. (Electro Luminance) is used as a representative.

Meanwhile, in the process of producing the flat panel display panel, the panel is inspected for appearance and electrical defects before assembling the backlight and the driving circuit. The inspection process is performed by applying power to the data line and the gate line provided in each unit panel in the inspection apparatus so that the operator visually inspects whether the panel is defective, and FIG. 4 illustrates an example of a conventional inspection apparatus. It is a perspective view shown.

As shown, the database 200 is mounted on the upper surface of the stage 100 in the horizontal direction, and the gate base 300 is mounted in the vertical direction, and the data needle 211 is provided on the database and the gate base, respectively. A plurality of gate probes 310 including the data probe 210 and the gate needle 311 are mounted.

Accordingly, when the panel is loaded on the work table (not shown) provided behind the stage 100, the work table is advanced to set the panel at the center of the stage. At this time, the data needle 211 and the gate needle 311 are grounded at the contacts of the contact pads provided on the side of the panel, so that power is applied to the data line and the gate line of the panel to perform the inspection.

 However, in the conventional inspection apparatus, since the position of the probe is fixed on the stage, when it is desired to inspect panels of different sizes, it is inconvenient to adjust the position of the probe by installing a separate adapter (not shown) on the base. There was a ham.

That is, by installing and changing the adapter according to the size of the panel, not only waste of manpower and time, but also a positional error occurs during the installation of the adapter and the positioning of the probe, and the accuracy of inspection is deteriorated. There was this.

In addition, when the difference between the maximum size and the minimum size of the panel that can be mounted on the stage is large, two to three adapters must be installed in the panel inspection, which greatly reduces the convenience of work and the accuracy of the inspection. There were many problems.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose of the flat panel display panel inspection apparatus that can be set quickly and accurately by moving the base and the probe according to the size of the panel to be loaded In providing.

One aspect of the present invention for achieving the above object is a stage that is installed in front of the worktable is loaded panel, a first base installed in the horizontal direction on the stage and a plurality of data probes, the stage In the flat display panel inspection apparatus including a second base installed in the vertical direction on the plurality of gate probes are mounted, wherein the first and second bases are installed to be movable in position according to the size of the loaded panel, The data probe and the gate probe may be installed to be movable along the contacts disposed on the panel.

Accordingly, when the panel is loaded, the first and second bases are respectively moved according to their sizes, and then the probes are moved in accordance with the contacts on the panel, thereby quickly and accurately inspecting panels of various sizes.

In moving the probe, an aspect of the present invention is that the first rail member is installed in the horizontal direction of the panel in the first base, the second rail member is installed in the longitudinal direction of the panel in the second base, The data probe and the gate probe are slidably mounted on the first and second rail members.

In moving the first and second bases, an aspect of the present invention is characterized in that the first and second bases are respectively provided on a plurality of LM guides, and the LM guides are disposed at the same inclination angle toward the panel. do.

Aspects of the present invention described above will become more apparent through preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail so that those skilled in the art can easily understand and reproduce the present invention.

1 and 2 are a perspective view and a plan view showing an embodiment of the present invention, Figure 3 is an operating state diagram of FIG. As illustrated, the flat panel display panel inspection apparatus of the present invention includes a work table (not shown) to which the panel P supplied from the outside is loaded, a stage 10 having a rectangular frame shape installed in front of it, and the stage image. The first base 20 is installed in the horizontal direction and the plurality of data probes 21 is mounted, and the second base 30 is installed vertically on the stage and the plurality of gate probes 31 are mounted. It is provided.

In this case, the first and second bases 20 and 30 are installed to be movable in position according to the size of the loaded panel, and the data probe 21 and the gate probe 31 are respectively located along the contacts disposed on the panel. Characterized in that the movement is possible.

Accordingly, when the panel is loaded on the work table, the operator may move and reposition the first and second bases 20 and 30 according to their sizes.

In addition, a typical LCD panel is provided with a data driver IC (not shown) on the horizontal side and a gate driver IC (not shown) on the vertical side. The arrangement of the contacts formed on the driver IC differs depending on the size of the panel. .

However, in the present invention, since the data probe 21 and the gate probe 31 can be moved on the first and second bases 20 and 30, the position adjustment of the first and second bases is completed according to the size of the panel. The data probe and the gate probe may be rearranged according to the position of the contact.

To this end, in the present embodiment, the first rail member 22 is installed in the horizontal direction of the panel on the first base 20, and the second rail member 32 is disposed in the longitudinal direction of the panel in the second base 30. The data probe 21 and the gate probe 31 are slidably mounted on the first and second rail members, respectively.

In addition, the first and second bases 20 and 30 are respectively provided on the plurality of LM guides 23 and 33, and the LM guides are disposed at the same inclination angle toward the panel P. This is to prevent mutual interference and collision in the process of moving the first and second bases toward the panel side when the panel having a small size is loaded.

On the other hand, the first and second base 20, 30 is provided with an operating member (not shown) to automatically transfer in accordance with the direction of movement, and a control unit for controlling the operating member to adjust the transfer amount according to the size of the panel (Not shown), the position of the said 1st, 2nd base can be adjusted more quickly and simply.

The actuating member and the control unit is a technology that can be easily implemented by those skilled in the art. The servo motor is installed on the stage 10 and the ball screws driven by the servo motor are driven by the first and second bases 20 ( 30) or a simple method using a reciprocating cylinder.

As described above, the present invention can be set quickly and accurately by moving the base and the probe according to the size of the panel to be loaded. Unlike the conventional method, the convenience of work and the precision of inspection can be improved, as well as the replacement of the adapter. And it has the effect of minimizing the waste of manpower and time due to the probe alignment.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. . Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
