The present invention relates to a multi-standard panel support device for a work table for an LCD inspection apparatus, and in detail, the size of the work table is varied according to the size of the LCD panel so that LCD panels having different sizes are used using one work table. The present invention relates to a multi-standard panel support device of a work table for an LCD inspection device that enables testability to maximize equipment utilization.

In general, a display panel such as an LCD (Liquid Crystal Display) panel, an organic EL panel, or the like is manufactured through a plurality of manufacturing steps. As the process proceeds, a predetermined lighting state test process for testing the lighting state of the display panel is performed to ensure that only high quality products that maintain a lighting state of a predetermined level or more are always shipped.

An LCD panel test process, which is one of display panels according to the prior art, is as follows.

When the operator feeds the test LCD panel to a supply that is level with respect to the ground, the supply is rotated at an inclined angle with respect to the ground (the angle at which the operator can most accurately see the LCD panel being tested in the test section), and then transported. The unit moves the LCD panel supplied to the supply unit to the test unit. In the test unit, the LCD panel and the test unit are electrically connected to transmit and receive electric signals, and the backlight of the LCD panel is turned on to transmit the light to the outside through the LCD panel. In this process, the operator visually checks the LCD panel and visually checks the overall color of the LCD panel, a defective pixel rate, and the like to determine the defect of the LCD panel.

In addition, after darkening the inside of the chamber in which the camera is mounted, the panel mounted on the upper side of the work table as a camera is inspected by automation.

Hereinafter, the operation of the multi-standard panel support apparatus of the work table for the LCD inspection apparatus according to the present invention will be described in detail with reference to FIGS.

First, when the first driving motor 125 is driven to adjust the first moving base 122 of the first moving base module 120 to the thickness of the LCD panel (not shown), the first ball screw ( 124 is moved vertically to move the first moving base 122 fastened by the first bracket 124-1 up and down. At this time, the first moving base 122 is moved up and down along the first LM guide 121 by the first LM guide 121 connected to the first moving base 122.

At the same time, when the first moving base 122 moves, the second moving base 132 and the third moving base 141 of the second moving base module 130 are also moved by the fix block 144. In this case, the second moving base 132 and the third moving base 141 are moved up and down along the third LM guide 142 by the fix block 144.

In addition, when the second driving motor 135 is driven to adjust the second moving base 132 of the second moving base module 130 to the length of the LCD panel, this causes the second ball screw 134 to be horizontal. The second moving base 132 fastened by the second bracket 134-1 by moving in the direction is moved to the left and right.

That is, when the first moving base 122 is narrowed, the second moving base 132 is also narrowed accordingly, and at this time, the third moving base 141 located on the left side of the second moving base 132 is located on the upper side thereof. The third moving base 141 located on the right side protrudes toward the side of the second moving base 132 located on the lower side thereof and narrows as a whole.

In this state, when the second moving base 132 located on the upper side is moved to the right, and the second moving base 132 located on the lower side is moved to the left, the third moving base 141 located on the left is moved to the right. The third moving base 141 located on the right side is moved to the left side to adjust the size of the work table 100.

Therefore, by adjusting the size of the worktable according to the size of the LCD panel, it is possible to test LCD panels of various standards with one worktable.

According to the multi-standard panel support apparatus of the work table for the LCD inspection apparatus of the present invention configured as described above, the work table is variable in size according to the size of the LCD panel on the base plate using a single work table LCD By allowing the panel to be tested, the LCD panel can be quickly inspected, minimizing the time required to assemble and disassemble the alignment stage.
