Description

TFT-LCD Panel align apparatus {TFT-LCD Panel align apparatus}

The present invention relates to a TFT-LCD (Tin Film Transistor-Liquid Crystal Display) panel alignment device, and more particularly, to freeze the TFT-LCD panel without using an alignment mark. The present invention relates to a TF-LC panel alignment device.

TF-LC, an ultra-thin liquid crystal display device, is one of display devices that serve as an interface between electronic devices and humans. These TFT LCDs are not only used for a few centimeters to a few millimeters in thickness but are also widely used because they are lightweight and consume low power. In particular, the recent development of a large TFT-LCD more than 30 inches (Inch) has been expanding the use of the TFT-LCD not only in the PC monitor (Monitor) area but also in the TV area.

On the other hand, TF-LCD has a disadvantage that it is relatively expensive compared to the cathode ray tube which is used as a display device. Therefore, recently, in order to overcome these disadvantages, the entire process of the production and assembly process of TF-LCD has been automated.

However, TFT-LCD has a panel in which liquid crystal is injected between the substrate and the substrate, a printed circuit board (PCB) with various circuit elements for driving the panel, and a panel that illuminates the panel from the rear of the panel. It is very difficult to automate the entire process of the production and assembly process because it is necessary to include a backlight and a top sash that combines the panel and the backlight.

In particular, the panel alignment process of aligning the panel to combine the panel with the backlight is difficult because the alignment mark formed on the panel is often difficult to see. .

Specifically, at least two alignment marks are formed in an edge portion or an edge portion of the conventional panel so as to be used when the panel is aligned. Therefore, the conventional panel alignment apparatus recognizes how far the panel is from the standard position by using the alignment mark, and then completes the alignment of the panel by correcting or correcting it.

Thus, the operator can not only move the panel 80 seated on the panel seat 150 in the front, rear, left and right directions, but also rotates a predetermined angle.

Hereinafter, the operation and effects of the present invention TFC LCD panel alignment device 100 configured as described above will be described in detail.

First, when the TFT-LCD panel 80 is loaded on the pallet mounting table 138 of the first alignment module 140 by the panel loading device 100 (not shown) seated inside the pallet 90, The panel carrier 120 of the first alignment module 140 adsorbs any point of the panel 80 seated on the pallet 90 by a plurality of vacuum pads 126 under the control of the central control module. It will raise about 2mm.

Thereafter, when the panel 80 is completed by about 1 to 2 mm, the panel carrier 120 releases the locking unit 132 by raising the piston rod 133 inserted into the fixing member 137 by a predetermined distance.

Subsequently, when the locking unit 132 is released, the panel carrier 120 moves the panel 80, which is raised by about 1 to 2 mm, in the direction in which the alignment protrusions 95 inside the pallet 90 are formed in the pallet 90. It is pushed by a predetermined size force. At this time, the pallet 90 is already supported by the pallet latching jaw 139 formed on the pallet seating table 138, and a plurality of pallets 90 are arranged in the pallet catching jaw 139 in the interior of the pallet 90. Since the alignment protrusion 95 is provided, the panel 80 in which the panel carrier 120 is raised by about 1 to 2 mm is thus moved in the direction in which the alignment protrusion 95 inside the pallet 90 is formed inside the pallet 90. When pushed into the pallet 90 and the alignment protrusion 95 inside the pallet 90 does not flow, only the panel 80 inside the pallet 90 alignment protrusion 95 inside the pallet 90. It flows in one direction and one side thereof is in close contact with the alignment protrusion (95). In particular, the panel carrier 120 is provided with an elastic spring unit 131 for rotating the panel adsorption portion 122 of the panel carrier 120 at a predetermined angle by a predetermined elastic force. When the panel 80, which is raised by about 2 mm, is pushed in the direction in which the alignment protrusion 95 inside the pallet 990 is formed in the pallet 90, the panel 80 adsorbed to the panel adsorption part 122 has an elastic spring. By the action of the unit 131, one side thereof is in contact with and in close contact with the plurality of alignment protrusions 95 corresponding to the one side thereof. Therefore, the panel 80 seated on the pallet seating table 138 and the pallet 90 has at least one side thereof in contact with the plurality of alignment protrusions 95 provided on the pallet 90 so that the panel 80 is approximately The first primary alignment is to be completed.

Subsequently, when the rough primary alignment is completed, the panel carrier 120 lowers the adsorption raised panel 80 back to the pallet 90 and then rises a predetermined distance upward.

Subsequently, the panel carrier 120 lowers the piston rod 133 by a predetermined distance, thereby inserting the fitting protrusion 134 formed at the end of the panel carrier 120 into the fitting groove 136 of the fixing member 137. 132 is locked again.

Subsequently, when the locking is completed, the panel carrier 120 descends again and is aligned first, and then absorbs the panel 80 seated on the pallet 90 to mount the panel of the second alignment module 190 ( 150). Therefore, the panel 80 is seated on the panel seat 150, the seat transfer unit of the second alignment module 190, the panel seat 150 on which the panel 80 is seated, such as before and after or left and right The panel 80 seated on the panel seat 150 is transferred to the vision aligning unit 180 by flowing a predetermined distance in the direction of.

Then, when the panel 80 is transferred to the vision aligning unit 180, the first camera unit 181 and the second camera unit 186 of the vision aligning unit 180 are transferred to both sides of the panel 80, respectively. By taking a picture of the edge portion of the panel 80, the edge portion 85 of the panel seating table 150 is located exactly at which coordinate point or the panel 80 is exactly seated on the panel seating 150 in the form Will be detected. At this time, when each corner portion 85 of the panel 80 does not fall within the photographing range of the first and second camera units 181 and 186, or when each corner portion 85 of the panel 80 does not coincide with any reference position. In addition, the central control module moves or rotates the panel 80 to a predetermined position by using the seat transfer unit and the rotating unit 177. In this case, the seating unit transfer part and the rotating part 177 move the panel 80 only little by little or rotate it little by little, so that the panel 80 enters into the photographing range of the first and second camera units 181 and 186 or the panel 80. Each corner 85 of) will be matched to any reference position. This is because the panel 80 seated on the panel seat 150 is already approximately aligned in the first alignment module 140. Therefore, the central control module is to accurately detect the position of the panel 80 currently seated on the panel seat 150 to complete the secondary alignment, which is a detailed alignment.

Subsequently, the alignment completed panel 80 is to perform a bonding process with the backlight to be continued to the subsequent process, the seat transfer unit is not shown panel transfer robot (not shown) is seated on the panel seat 150 The panel 80 is transferred to a predetermined predetermined position so as to pick up adsorption (Pick up). At this time, the central control module is already aligned with the panel 80 seated on the panel seat 150, the panel transfer robot of the panel 80 seated on the panel seat 150 from the central control module By receiving the position, the pickup of the exact pickup position of the panel 80 is able to perform the exact combination of the panel 80 and the backlight.

As described above, the TFT-LCD panel aligning apparatus according to the present invention aligns the panel by photographing both edges of the panel by using a vision camera, thereby eliminating the need for the conventional alignment mark. The effect is possible to align.

In addition, the TFT-LCD panel aligning device according to the present invention aligns the panel since the first primary alignment is made by using the alignment protrusion provided on the pallet, and then the second panel is aligned with the vision camera. The time required can be greatly reduced, and the effect can be more accurate alignment.
