Description
본 발명은 평면TV LCD프레임을 프레스 가공함에 있어서, 전 공정을 연속적으로 자동화가공 하도록 한 LCD프레임 가공방법에 관한 것이다.The present invention relates to an LCD frame processing method for continuously processing the entire process in press working a flat panel LCD LCD frame.
산업이 발전함에 따라 공간활용도를 크게 하기 위하여 TV의 화면은 보다 크게 하면서도 TV의 두께는 작게 하는 기술이 개발되어 평면TV인 LCD가 개발되었다.With the development of the industry, in order to increase the space utilization, the TV screen is made larger and the TV thickness is smaller.
상기한 LCD를 완성함에 있어서는 LCD의 화면크기를 결정하고 화면 외각을 보호 하기 위한 외곽프레임을 구성하는 것이 필수적이다.In completing the LCD, it is essential to configure an outer frame to determine the screen size of the LCD and protect the screen exterior.
이와 같은 외곽 프레임은 철판으로 가공하여 구성하는 것이 일반적이나 이때 화면의 크기가 결정되어야 하기 때문에 그 정밀도가 대단히 중요하며 연속적으로 자동화 가공하는 것 또한 중요하기 때문에 가공방법에 따른 금형의 배열과 가공방법공정의 배열이 원가 절감의 원인이 되고 있다.Such an outer frame is usually made of steel sheet, but the precision of the screen is very important because the size of the screen must be determined, and the continuous automatic processing is also important. Arrangement is causing cost reduction.
상기한 LCD의 외곽테를 구성하는 프레임은 철판을 프레스 가공하여 완성하게 되는데 이때 다양한 공정을 완성하는데 따른 금형과 이들 공정에 따른 금형의 배열이 작업의 효율성을 증대시키는 결정적인 원인이 된다.The frame constituting the outer frame of the LCD is completed by pressing a steel plate, and the mold according to the various processes and the arrangement of the molds according to these processes is a decisive factor for increasing the work efficiency.
뿐만 아니라 기본적으로 공급되는 철판에서 얇고 긴 샤시를 보다 효율적으로 블랭킹하여 분할하도록 설계하여 자재의 손실을 최소화하도록 하여 원가를 절감 하도록 하는 것이 중요하다 할 것이다.In addition, it is important to reduce cost by minimizing material loss by designing the thin and long chassis more efficiently by blanking and dividing the basic steel sheet.
또한 지금까지는 프레스 가공을 함에 있어서 필수적으로 사용하였던 가공오일 때문에 가공작업 완료 후 도금이나 도장 등의 후 가공 처리를 위하여 가공오일을 제거하는 탈지공정이 필연적으로 따라야만 하였다. In addition, the degreasing process of removing the processing oil is inevitably followed by the processing oil, which has been essentially used in press working until now, for processing after plating and painting.
본 발명은 상기한 지금까지의 문제점을 해결하고자 평면TV 모니터인 LCD프레임을 제조함에 있어서,The present invention in manufacturing an LCD frame that is a flat-panel TV monitor to solve the above problems so far,

상기한 본 발명은 LCD의 외곽테를 구성하는 프레임을 프레스 가공함에 있어서 다양한 공정을 완성하는데 따른 금형과 이들 공정에 따른 금형의 배열을 자동으로 작업이 가능하도록 하여 작업의 효율성을 증대시킬 뿐만 아니라, 기본적으로 공급되는 철판에서 얇고 긴 샤시를 보다 효율적으로 블랭킹하여 분할하도록 설계하여 자재의 손실을 최소화하도록 하여 원가를 절감하였으며, 지금까지 프레스 가공을 함에 있어서 필수적으로 사용하였던 가공오일을 사용하지않아서 가공작업 완료 후 도금이나 도장 등의 후 가공 처리를 위하여 가공오일을 제거하는 탈지공정을 생략하여 작업능률을 향상시키고 원가를 절감하는 효과는 물론 환경오염의 원인을 줄이는 효과를 기대할 수 있는 신규한 발명이다. The present invention as described above not only increases the efficiency of the work by automatically working with the mold according to the completion of various processes in the press forming the frame constituting the outer frame of the LCD and the mold according to these processes, It is designed to blank and divide thin and long chassis more efficiently from the iron plate that is basically supplied, thereby minimizing material loss, thereby reducing the cost, and processing work without using the processing oil that has been essential to press processing. It is a novel invention that can improve the work efficiency, reduce the cost and reduce the cause of environmental pollution by omitting the degreasing process to remove the processing oil for post-processing such as plating or painting after completion.
실시예;Example;
LCD프레임을 가공함에 있어서,In processing the LCD frame,
제1공정: 소재공급공정First step: material supply process
가공소재인 철판롤을 풀어서 블랭킹가공을 위하여 프레스에 세팅된 블랭킹금형에 가공하고자 하는 철판을 피더로 정확하게 공급한다.The iron plate roll, which is a workpiece, is released and the iron plate to be processed is precisely supplied to the blanking mold set in the press for blanking processing.
제2공정: 블랭킹공정Second Process: Blanking Process
롤 상태로 감겨진 철판이 상기 피딩공정의 피더에 공급되면 공급된 철판을 가공에 필요한 크기로 따내는 것과 동시에 외측으로는 긴 샤시가 형성되고 내측에는 짧은 샤시가 형성되게 필요한 홀을 피어싱하고 엠보싱을 하는 등 편면상의 가공을 완성한다.When the iron plate wound in the roll state is supplied to the feeder of the feeding process, the supplied iron plate is pulled out to a size necessary for processing, and a hole is pierced and embossed to form a long chassis on the outside and a short chassis on the inside. To complete the processing on one side.
제3공정: 분할공정Third Process: Division Process
상기 블랭킹공정에서 평면상의 가공과 동시에 블랭킹 된 소재를 이송로봇이 이송하면 분할금형으로 외측의 긴샤시와 내측의 짧은 샤시를 사용용도에 맞게 4조각으로 분할한다.In the blanking process, when the transfer robot transfers the blanked material at the same time as the processing on the plane, the long chassis on the outside and the short chassis on the inside are divided into four pieces according to the intended use.
제4공정: 사각정렬공정Fourth Step: Square Alignment Process
상기 분할공정에서 분할된 4조각의 소재가 이송로봇에 의하여 이송되면 외측에 성형된 긴 샤시를 외측으로 벌려줌과 동시에 내측성형된 짧은 샤시를 90°돌려서 사각프레임 형상으로 정렬한다.When the four pieces of material divided in the dividing process are transported by the transfer robot, the long chassis formed on the outside is opened to the outside, and the short chassis formed on the inner side is rotated 90 ° to align in a rectangular frame shape.
제5공정: 코킹공정5th process: Caulking process
상기 사각 정렬 공정에서 사각프레임 형상으로 정렬된 소재의 4조각의 소재를 그 상태로 로봇이 이송하면 이들 4조각의 프레임이 단일 체가 되도록 서로 일체로 연결하여 사각프레임을 완성한다.When the robot transfers four pieces of material aligned in the shape of a square frame in the rectangular alignment process, the four pieces of the frame are integrally connected to each other so as to form a single body, thereby completing the square frame.
제6공정: 밴딩공정6th Step: Bending Process
상기 코킹공정에서 단일체로 형성된 사각프레임 형상의 소재의 로봇이 이송하면 외곽의 절곡부를 절곡하여 하나의 틀로 구성한다.In the caulking process, when the robot of the rectangular frame-shaped material formed as a single body is transferred, the outer bent portion is bent to form a frame.
제7공정: 피어싱공정7th step: Piercing process
상기 밴딩공정에서 밴딩된 소재를 로봇이 이송하면, 화면의 크기를 정확하게 일치시키도록하기위하여 평면에 화면 사이즈를 설정하기 위한 기준 홀을 천공한다.When the robot transfers the bending material in the bending process, a reference hole for setting the screen size on a plane is drilled to accurately match the size of the screen.
제8공정: 챔퍼공정Eighth Step: Chamfer Process
상기 피어싱공정에서 피어싱한 소재를 로봇이 이송하면 소재의 표면과 이면에 가공 버가 발생한 것을 제거하여 제품이 깔끔하도록 마무리한다. When the robot transfers the material pierced in the piercing process, the processing burrs are removed from the surface and the rear surface of the material to finish the product neatly.
제9공정: 검사공정Step 9: Inspection Process
