On the other hand, in the manufacture process of flat display board, before assembling backlight and driving circuit, to test to the outward appearance and the electric defective of flat display board.In checkout procedure, detecting device provides electric power to data line and the gate line that is arranged on each flat display board, thereby the workman is the defective of detecting plane displaying board with the naked eye.Fig. 4 shows the planimetric map of conventional planar display board detecting device.
As shown in FIG., on the upper surface of platform 100, along continuous straight runs is equipped with data pedestal 200, and gate pedestal 300 vertically is installed.On data pedestal 200 and gate pedestal 300, be separately installed with a plurality of data detector 210 and a plurality of grid detectors 310 with grid probe 311 with data probe 211.
Like this, when on the worktable (not shown) that flat display board is loaded into platform 100 back, worktable moves forward the middle part with platform 100 that flat display board is packed into.At this moment, data probe 211 and grid probe 311 are connected on the contact point of the contact plate that is arranged on the flat display board side, thereby electric power is provided on the data line of flat display board and the gate line to detect.
Yet according to traditional slab display panel detector, position of detector is fixed on the platform.Therefore, when checking the flat display board of other different size, extra adapter (not shown) must be installed on pedestal regulate position of detector.
In other words, because adapter must be set, and slab display panel detector also must change according to the size of flat display board, so wasted manpower and time.In addition since at mounting adapter and when detector position is set detector position can produce error, therefore, the testing accuracy of flat display board can reduce.
In addition, when between full-size that can be installed in the flat display board on the platform and the minimum dimension very big difference being arranged, two or three adapters must be installed in the testing process of flat display board with mutual superposition.Therefore, the convenience of work and the precision of detection have been reduced significantly.
Summary of the invention
Therefore, based on consideration, make the present invention to above-mentioned and/or other problem.The object of the present invention is to provide a kind of slab display panel detector that can move and place pedestal and detector quickly and accurately according to the size of the flat display board that is loaded.
According to the present invention, above-mentioned and other purpose can realize that it comprises by a kind of like this slab display panel detector: platform, the front of the worktable of its loading flat display board mounted thereto; First pedestal, along continuous straight runs are installed on the platform, on this first pedestal a plurality of data detectors are installed; And second pedestal, vertically be installed on the platform, a plurality of grid detectors are installed on this second pedestal, first and second pedestals are mounted the size that is used for according to the flat display board that is loaded and move, and data detector and grid detector are mounted the contact point that is used for along being arranged on the display board and move.
Like this, move first and second pedestals, and move corresponding detector, can check the flat display board of various sizes rapidly and accurately along the contact point on the flat display board by size according to the flat display board that is loaded.
Aspect mobile detector, according to an aspect of the present invention, first pedestal comprises first rail guide piece, is installed in first pedestal along the horizontal direction of flat display board; Second pedestal comprises second rail guide piece, be installed in second pedestal along the vertical direction of flat display board, and data detector and grid detector is installed in respectively on first and second rail guide pieces to slide.
Aspect mobile first and second pedestals, according to an aspect of the present invention, first and second pedestals are installed in respectively on a plurality of linear motion guide devices, and these linear motion guide devices are arranged as with identical pitch angle towards flat display board.
Description of drawings
By below in conjunction with the description of accompanying drawing to embodiment, objects and advantages of the present invention will become clear and understand easily.Among the figure:
Fig. 1 shows the skeleton view of slab display panel detector according to a preferred embodiment of the invention;
Fig. 2 is the planimetric map of slab display panel detector shown in Figure 1;
View shown in Figure 3 shows the working condition of the slab display panel detector among Fig. 2;
Fig. 4 shows the planimetric map of traditional slab display panel detector.
Embodiment
Following with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 shows the skeleton view of slab display panel detector according to a preferred embodiment of the invention, and Fig. 2 is the planimetric map of slab display panel detector shown in Figure 1.As shown in the figure, slab display panel detector according to this preferred embodiment of the invention comprises a worktable (not shown), and the flat display board P that provides from the outside is provided on it; A square platform 10, it is installed in the front of this worktable; One first pedestal 20, its along continuous straight runs is installed on the platform 10, and a plurality of data detectors 21 are installed on it; And one second pedestal 30, it vertically is installed on the platform, and a plurality of grid detectors 31 are installed on it.
First and second pedestals 20 and 30 can move according to the size of the flat display board P that is loaded, and data detector 21 and grid detector 31 can move along the contact point that is arranged on the flat display board.
Therefore, when being loaded into flat display board on the worktable, the workman moves first and second pedestals 20 and 30 to arrange this first and second pedestal 20 and 30 according to the size of flat display board P.
Usually, LCD panel comprises data driver IC (not shown) that along continuous straight runs is provided with and the gate drivers IC (not shown) that vertically is provided with.The layout of the contact point that forms on driver IC changes with the size of flat display board P.
Yet according to the present invention, data detector 21 and grid detector 31 can move on first and second pedestals 20 and 30.Like this, when finishing the rearranging of first and second pedestals 20 and 30 according to the size of flat display board P, data detector 21 and grid detector 31 can rearrange according to the position of contact point.
