Description
The present invention relates to a cell mounting apparatus for a liquid crystal display panel inspecting apparatus, and more particularly to a cell mounting apparatus for a liquid crystal display panel inspecting apparatus capable of stably mounting a liquid crystal display panel to be inspected on a work table.
2. Description of the Related Art Generally, an inspection apparatus for a liquid crystal display panel is provided with a probe unit for fixing a display panel to a point where an operator is located so that a liquid crystal display panel (including a liquid crystal display or a flat panel display) And to inspect using an inspection device of a suitable size according to the size of the liquid crystal display panel.
Liquid crystal display panels (TFT-LCD), which is the flagship product of flat panel displays, are rapidly becoming large-sized and high-resolution with the achievement of mass production technology and research and development, Has been developed and replacing existing CRT (cathode ray tube) products, and its proportion in the display industry is gradually increasing.
In recent information society, display has become more important as a visual information delivery medium. Especially, the importance of low power consumption, thinning, light weight, high image quality and portability It is getting higher.
Since liquid crystal display panels are not only capable of satisfying these conditions of a flat panel display but also have a mass production capability, various new products using the same are rapidly being developed, and the proportion of the electronic industry is more than that of semiconductors It is emerging as a next-generation mainstream technology.
Such a liquid crystal display panel is subjected to a lighting test at the final stage of the manufacturing line, which uses a probe unit in a specific inspection facility to perform disconnection inspection and color inspection for each of the data lines and gate lines of the liquid crystal display panel, And so on.
Meanwhile, liquid crystal display panels are currently being offered in various sizes such as 30 inches, 40 inches, 46 inches, 52 inches, and 57 inches. In order to inspect all of these various sizes of liquid crystal display panels, It is already available.
In such a liquid crystal display panel inspecting apparatus, a cell transferred by a carrier is mounted on a work tabel. That is, the cell is transported by the carrier and is stably placed on the work table, so that the cell is inspected for defects or the like.
In addition, the size of the cell is slightly larger than the size of the cell to be stably placed on the work table. Such a cell has a mounting area of a predetermined width so as to be stably placed on the work table.
That is, the cell is manufactured with a size larger than the size of each inch to be manufactured, and the mounting region is formed on the edge of the cell so as to be stably placed on the work table by a predetermined width.
Such a mounting area is formed to be approximately 2 mm or more, and two cell alignments are vertically provided on both sides of the work table.
The cell alignment causes the cell to be in the correct position and adjusts to place the cell in the precise position of the worktable if necessary.
Meanwhile, in recent years, the width of the bezel (frame) for fixing the liquid crystal display panel has been greatly narrowed, and accordingly, the mounting area of the cell has also become very narrow.
As the mounting area of the cell narrows, the moved cells can not be stably mounted on the work table. Accordingly, there is a problem that an additional device for mounting the cells in a more correct position on the work table is required.
In addition, the cells transferred to the carrier have a problem that they are placed on the work table or fall into the work table when the work cell is mounted on the work table.
For example, a 'probe apparatus' is disclosed in
The probe device according to
The following
The liquid crystal panel inspection apparatus according to
However, the liquid crystal display panel inspection apparatus according to the related art can not stably mount the moved cells on the work table as the mounting area of the cell narrows, and accordingly, There is a problem that when the cell is mounted on the work table, the cell is placed in a wrong state on the work table or falls into the work table.
SUMMARY OF THE INVENTION An object of the present invention is to provide a cell mounting apparatus for a liquid crystal display panel inspecting apparatus capable of stably mounting a cell on a work table.
Another object of the present invention is to provide a cell mounting apparatus for a liquid crystal display panel inspecting apparatus capable of satisfactorily mounting a cell having a mounting area of 0.5 to 2 mm, which is very narrow, on a work table.
According to an aspect of the present invention, there is provided a cell mounting apparatus for inspecting a liquid crystal display panel, comprising: a work table installed to mount cells having different sizes; And a cell support installed on both sides of the work table to mount the cell, wherein the cell support includes a step formed so that a part of the mounting region of the cell is stably mounted.
Wherein the cell support comprises a triangular base provided on the work table; A fixed block fixed to the upper surface of the triangular base and having a cylinder at one side thereof; A movable block movably installed along the fixed block by the cylinder; And a horizontal moving block fixed to an upper surface of the moving block and having the stepped portion on which the cell is mounted.
The triangular base is characterized in that one side is higher and the other side is lower.
And the inclined surface is inclined at an angle of 30 to 40 degrees.
Wherein the cell support comprises a cell support which is rotatably disposed by an actuator provided on the work table; A stopper fixed to one upper surface of the work table so as to restrict movement of the cell; And a pusher movably installed on the upper surface of the other side of the work table to adjust the position of the cell.
As described above, according to the cell mounting apparatus of the apparatus for inspecting a liquid crystal display panel according to the present invention, the cell can be more stably mounted by the cell support provided on the work table, In addition, the cell of 1 mm or less can be stably mounted on the cell support, and the cell can be mounted on the work table more easily and stably.
