A method of inspecting the direction of fabrication (1 in FIG. 1) is a method of inspecting the bundle spacing between the bundles of very dense objects. (2 in the diagram) is placed on the rubbing cloth (3 in the diagram), and a vibration transmitting object (5 in the diagram) is placed on the diaphragm (9, circle or square shape, etc.) under the rubbing cloth. It includes a vibration transmission device (6 of the Figure) is mounted on, the vibration transmission device includes transmitting a waveform (8 of the representative diagram) made in the wavelength forming device (7 of the Figure), Speakers, solenoid valves, pneumatic cylinders, etc.) includes a device for processing data of amplitude and frequency modulated wavelengths formed in computers and embedded systems, and the diaphragm removes reflected waves through a vibration absorber (9 in the diagram).

현재 LCD TV나 NOTE BOOK, 핸드폰등에 고화질의 디스플레이장치를 사용되어 지고 있으며, 그 디스플레이 장치는 LCD나 OLED 또는 PDP등등으로 구성되어져 있고 현재 LCD는 TV나 NOTE BOOK등등에 사용되어지고 있다. 이러한 LCD의 가공은 BARE GLASS(아무 패턴이 없는 글라스)에 패턴을 입히고 그 글라스에 액정이 고루 분포될 수 있도록 배향홈을 만들어주게 되고 그 후에 TFT와 COLOR FILTER를 합착하여 디스플레이 장치가 만들어지게 된다. 이때 액정이 고루 분포될 수 있도록 배향홈을 만들기 위해서 롤에 러빙포를 감아서 그 롤을 러빙기에 장착하여 러빙롤을 회전시키며 글라스 윗면에 홈을 만들어주게 된다. 이 홈이 액정이 배향되는 홈이며 배향 불량을 발생시킬 수 있는 것이 러빙포의 방향이나 포결 불량 및 결점 등등이며, 러빙포는 러빙포 컷팅과정을 거쳐 권포기로 러빙포를 러빙롤에 감고 러빙포 검사기(포빠짐이나 두께불량을 검출)나 목시검사하여 불량을 제거한 후 러빙기로 투입된다. 이러한 과정에서 러빙포 포결검사는 러빙포 컷팅과정 이전이나 권포과정 이전에 이루어 져야 하며 그래야 포 결의 방향을 맞추어서 컷팅하고 러빙롤에 제대로 장착되어 질 수 있는 것이다. 이러한 과정에서 본 발명은 러빙포의 권포시 포결의 방향을 맞추기 위한 필수적 과정이다.Currently, high-definition display devices are used for LCD TVs, note books, mobile phones, etc., and the display devices are composed of LCD, OLED, PDP, etc., and LCD is currently used for TV, NOTE BOOK, etc. The processing of the LCD forms a pattern on the glass glass (no pattern glass) and makes the alignment grooves so that the liquid crystal is evenly distributed on the glass, and then the display device is made by bonding the TFT and the color filter. At this time, in order to make the alignment groove so that the liquid crystals are evenly distributed, wrap the rubbing cloth on the roll and mount the roll on the rubbing machine to rotate the rubbing roll to make a groove on the upper surface of the glass. The groove is a groove in which the liquid crystal is oriented, and the orientation of the rubbing cloth can be caused by a rubbing cloth, a defect in defect, defects, and the like.The rubbing cloth is subjected to a rubbing cloth cutting process. After inspecting the machine (detecting blemishes or thickness defects) or visual inspection to remove defects, it is fed into the rubbing machine. In this process, the rubbing cloth test should be done before the rubbing cloth cutting process or before the winding process, so that the cutting can be cut in the direction of the catch and properly mounted on the rubbing roll. In this process, the present invention is an essential process for adjusting the direction of trapping during winding of the rubbing cloth.

현재의 러빙포 권포전에 러빙포를 사람이 코인을 사용하여 망치 등을 사용하여 일정한 위치에 진동을 전달한 후 코인의 이동각도를 확인하여 권포 각도와 러빙기의 러빙각도를 수정하는 상황이며, 이는 LCD생산시 여러 불량원인을 데이터화 하여 불량을 줄이는데 필요한 데이터화 및 사전에 공정개선을 통하여 불량을 줄이기 위한 LCD업체의 노력이다. 따라서, 러빙포결의 정확한 데이터 정보화가 필요하게 된 것으로서 본 발명의 검사방법으로 사람이 인위적으로 파장을 만드는 것보다 더욱 정확한 데이터를 취합 분석하며, 일정한 위치에 진동을 전달할 경우 다음 진동시 러빙포를 통해 동전이 받는 힘의 벡터는 동전면에 수직이 아니므로 데이터에 신뢰성을 주지 못하므로 코인의 이동위치에 따라 진동 전달물체를 이송시켜 코인의 수평면에 수직인 진동을 주기위한 방법이며,글라스 양산시 다량의 불량을 사전에 방지하고 이는 러빙포를 러빙롤 권포 전에 발생할 수 있는 불량요인을 제거함을 해결하고자 하는 과제로 삼는다.It is a situation where a person with a rubbing cloth before the current rubbing cloth roll sends a vibration to a certain position using a coin, etc., and then checks the moving angle of the coin to correct the winding angle and the rubbing angle of the rubbing machine. It is the efforts of LCD companies to reduce defects through data processing and advance process improvement necessary for reducing defects by dataizing various defect causes during production. Therefore, accurate data informatization of rubbing trap is required, and the inspection method of the present invention collects and analyzes more accurate data than a person artificially makes a wavelength, and delivers vibration to a certain position through a rubbing cloth at the next vibration. Since the force vector of the coin is not perpendicular to the coin surface, it does not give reliability to the data, so it is a method to transfer the vibration transmission object according to the coin's moving position to give the vibration perpendicular to the coin's horizontal plane. The problem is to prevent the defects in advance and to solve the problem that the rubbing cloth eliminates the defects that may occur before the rubbing roll winding.

포 결의 방향(도 1의 1과 2)을 검사하기 위해서는 러빙포 전체 포 결의 방향을 측정하여야 하는데 이는 포 다발(도 1의 1)이 서로 붙어있고 또한 포 다발에 포함된 포 낱개의 실들도 너무 많아서 포 다발의 방향을 측정하는데 어려움이 따르므로 원형 코인 형태의 물체를 러빙포 위에 올려놓고 진동판에 진폭 및 주파수를 변조할 수 있는 진동형성장치를 통하고 진동형성장치는 진동전달장치를 통해서 진동 전달물체에 진동을 전달하며 물리적 진동은 진동판을 통해 러빙포로 전달하여 러빙포 위에 있는 원형 형태의 코인을 움직이게 함으로서 포 결의 방향을 영상취득장치를 통해 컴퓨터가 계산하거나 영상처리장치를 통해 컴퓨터가 데이터 관리를 할 수 있다. In order to examine the direction of the fabric (1 and 2 of FIG. 1), the direction of the entire rubbing cloth should be measured. This means that the bundles (1 in FIG. 1) are attached to each other and the individual threads included in the bundle are too high. Since it is difficult to measure the direction of the gun bundle, it puts a circular coin-shaped object on the rubbing cloth and the vibration forming device can modulate the amplitude and frequency on the diaphragm, and the vibration forming device transmits the vibration through the vibration transmitting device. Vibration is transmitted to the object, and physical vibration is transmitted to the rubbing cloth through the diaphragm to move the circular coin on the rubbing cloth so that the computer calculates the direction of the capture through the image acquisition device or the computer manages the data through the image processing device. can do.

대략 1mm 간격(도 1의 4)의 포 다발을 사람이 직접 육안으로 검사하기 힘든 상황에서 현재 러빙포를 테이블에 올려놓고 동전 같은 작고 얇은 물체를 러빙포 위에 올리고 테이블에 손이나 도구를 사용하여 충격을 주면 동전이 움직이는 방향으로 포 결이 형성되었다는 것을 확인하여 권포 과정을 진행하게 되는데 이는 러빙포 방향 검사를 진행하는데 일정하지 않은 압력이 전달되는 문제점으로 인해 정확한 방향 데이터를 획득하는데 한계가 따르므로 본 발명을 통하여 정확한 진동을 구현하여 러빙포의 방향검사항목을 데이터 화하여 관리에 들어갈 수 있다.In a situation where it is difficult for a human to visually inspect a bundle of guns having an interval of about 1 mm (4 in FIG. 1), the current rubbing cloth is placed on a table, a small thin object such as a coin is placed on the rubbing cloth, and a hand or a tool is applied to the table. If it is given, it is confirmed that trapping is formed in the direction of coin movement and proceeds the winding process, which has a limitation in acquiring accurate direction data due to the problem of inconsistent pressure transmitted to the rubbing gun direction inspection. Through the invention, it is possible to enter the management by realizing the vibration inspection item of the rubbing cloth by implementing the accurate vibration.
