Description of the Invention: [Technical Field] The present invention relates to a flat panel display panel test apparatus, and more particularly to a flat panel display panel test apparatus, which can apply power to a data line and a gate pole line of a flat display panel. Detect the appearance and electrical failure of each flat panel display panel. [Prior Art] In general, a flat panel display panel is a next-generation display device for replacing a cathode ray tube (CRT) as an electric or computer monitor. Among them, a liquid crystal display (LCD), a plasma display panel (PDP), and an electroluminescence (EL) display are typical flat display panels. Another aspect: In the production of flat panel displays, the appearance and electrical faults of the flat panel are tested prior to assembly of the backlight and driver circuitry. The inspection/correction test device provides power to the data lines and m-throw lines provided on each of the flat display panels such that the operation s can visually detect the failure of the flat display panel. Figure 4 is a plan view of a conventional flat panel display panel test apparatus. On the upper surface of the red layer (10) as shown by the ® towel, a data base 2'0' is disposed in the horizontal direction and a gate base 3'' is disposed in the vertical direction. A plurality of data probes having a data pin and a plurality of gate probes 31 having a gate pin 311 are disposed on the data base and the closed base 300, respectively. Here, when the flat-panel display panel is loaded on a workbench behind the working layer (not shown in the drawings), the workbench moves forward to place the flat display panel at the center of the working layer 100. At this time, the f-pin 211 and the gate pin are connected to the contact point of the contact pad on the side of the flat panel display panel at position 6 (8) .1258591 to provide power to the data line and gate outline of the flat display panel. Then perform the test. However, according to the conventional flat panel display panel test device, the position of the probe is fixed on the working layer. Therefore, when detecting a size that is not a flat panel, an additional adapter (not shown) is attached to the base to adjust the position of the probe.

Moreover, when the position of the adapter and the fixed probe are set, an error in the position of the probe causes a decrease in the accuracy of the flat panel display H panel. Also, when the maximum size and the small size of the flat display panel that can be fixed on the working layer are large, two or two joints II are required to cover the flat display panel to cover each other. Thus, the convenience of work and the accuracy of detection are significantly reduced. SUMMARY OF THE INVENTION . In view of the above problems, it is a primary object of the present invention to provide a flat display panel measuring device which can quickly and accurately move and fix the pedestal and the probe by borrowing the size of the difficult-to-load plane. Thus, for the above purposes, the flat panel display panel of the present invention is tested: w; includes a working layer, a first pedestal, and a second pedestal. The working layer is also in front of the workbench of the flat panel display panel. The first pedestal is placed along the horizontal side of the 1258591 direction, and the _ turn probe is placed on the biliary. The second base is disposed on the working layer in a vertical direction, and a plurality of side probes are disposed thereon. Wherein, the first and second pedestals can be moved by the size of the flat panel display panel carried by the county' and the dragon probe and the _probe can be moved along the row __, the contact point on the panel. The domain-to-receives the corresponding probe corresponding to the plane of the loading and displays the "size of the board and moves the first and second bases" and moves along the contact points on the flat display panel, and reads and speeds accurately. Various sizes of flat panel. According to the invention 'on the moving probe, the first base includes a first obstructing member' 2 is disposed along the horizontal direction of the flat display panel. The second base includes There is a second trajectory structure which is disposed along the vertical direction of the flat display panel. The lean probe and the brake brim needle are respectively disposed on the first and second obstructing members to slide. On the moving first and second bases, the first and second bases are respectively placed on the plurality of cylindrical shaft guide rods, and the miscellaneous moving rods are arranged at the same inclined angle to the flat display benefit panel. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiment of the present invention is described in detail below. The drawing is a perspective view of a flat display panel according to a preferred embodiment of the present invention and the second _ For the flat panel display panel in Figure 1 1258591 (4) _ The present invention ± implementation of the touch _ shirt panel test device includes -= for the table (face shown in Cai), - rectangular working layer I., - the first base 2 〇 and a taxi The second base 30. Here, the flat display panel provided by the outside is mounted on the work $, and the rectangular working layer (7) is placed in front of the workbench. The first base ^ the flat direction of the female skirt in the guard layer On the 1G, a plurality of needles 21 are disposed thereon. The second base 3G is vertically mounted on the red layer 10, and a plurality of gate probes 31 are disposed thereon. The seat 20 and the second base 30 can be displayed according to the plane of the loading: the reverse size, and the data probe 21 and the brake pin 31 can be smoothly aligned along the __ chicken on the 11 panel. = plate, the root 'minus _ panel _ at the horizontal _ not in the figure Ux and the vertical __ drive - not in the figure), and the formation of Q is not according to the plane display TM contact points The mode will change depending on the size of the panel P. Gossip and 'on the data base 20 and the second base 30 according to the present invention; ^ pin n21 and The pole probe 31 can be in the first size, (4). Therefore, when the enthalpy 20 and the second pedestal 30 are completed according to the point p of the plane _ panel, the poor dynamometer can be rearranged according to the contact erection. The needle 21 and the gate probe 3 are to be touched 1258591. Finally, in this embodiment, a first track member 22 is disposed on the first base 20 along the horizontal direction of the flat display panel P, and a second The track member 32 is then disposed on the second base 3〇 along the vertical direction of the flat display panel P. The data probe 21 and the gate probe 31 are slidably mounted on the first track member 22 and the second track In addition, referring to FIG. 3, the first pedestal 20 and the second pedestal 30 are respectively disposed on the plurality of linear movement guides 23, 33, and the linear movement guides 23 and the phantom plane display state The panels P are arranged at the same oblique angle. In this way, when the small-sized flat display panel P is loaded, and the first base 2〇 and the second base are moved toward the flat display panel P, the first base 2 and the first base can be avoided. The two pedestals 3 〇 interfere or collide with each other. On the other hand, § $ again sets an operating member (not shown) to automatically transfer the first base 2 and the second base 3 () along the moving direction, and the setting controller (not shown) In order to control the transfer distance according to the size of the loaded flat display panel, the speed is recorded and the position of the second base is simply controlled. Here, the operations and the controller as described above can be easily performed by the operations known in the art, and can be caused by the working layer. On the top of the month, the motor will be driven by the servo motor - the ball screw (the fourth (four) asks to the pedestal 20 and the second pedestal 3 〇 to realize the operating member and the controller, or can be reduced The secret (4) simple mechanism to the real Lin dumping and control. A 1258591 size and (four) / invention, due to the ease of work and the accuracy of detection can be improved by the flat panel display panel, the exchange and probe _ way It is caused by the manpower 2 together with the syllabus. The money on the W, because of the indefinite book = this month, the preferred embodiment of (4) exposes the above, but it is not used to limit the price of 1 like the artist. The spirit and scope of the present invention is inconsistent with the scope of the invention. The scope of the application is based on the scope of the patent application attached to the brother-in-law (3).
