Abstract
본 고안은 적재된 물체를 작업자의 수동 조작에 의하여 업-다운 할 수 있도록 한 수동 대차에 관한 것으로, 본 고안은 수동대차에 적재된 무거운 중량의 반도체 제품을 전기적인 에너지 없이 원하는 높이 만큼 이격시킬 수 있으며, 반도체 제품을 원하는 높이 만큼 이격시킬 때 필요한 힘을 최소화하여 작업자의 피로도를 크게 경감시킴은 물론 작업자가 무리한 힘으로 반도체 제품을 이송할 때 발생하는 운반 안정성 저하를 방지한다.The present invention relates to a manual bogie that allows a loaded object to be pulled up and down by manual operation by an operator. The present invention can separate a heavy weight semiconductor product loaded on a manual bogie by a desired height without electrical energy. In addition, by minimizing the force required to separate the semiconductor product by the desired height, greatly reduces the fatigue of the operator, and also prevents the deterioration of transport stability that occurs when the operator transfers the semiconductor product with excessive force.
Description
본 고안은 수동대차에 관한 것으로, 특히 적재된 반도체 제품을 작업자의 수동 조작에 의하여 소정 높이 만큼 업-다운 할 수 있도록 한 수동 대차에 관한 것이다.The present invention relates to a manual bogie, and more particularly, to a manual bogie that allows a loaded semiconductor product to be up-down by a predetermined height by a manual operation of an operator.
최근들어 대부분의 산업 발달이 급속하게 진행되고 있는 바, 이와 같은 산업 발달은 방대한 정보를 매우 작은 면적에 저장, 방대한 정보를 단시간내 처리 및 처리된 정보를 디스플레이 하는 중요한 역할을 수행하는 반도체 칩, 액정표시장치(Liquid Crystal Display device)와 같은 반도체 제품의 성능 향상에 의하여 가속되고 있는 실정이다.Recently, most industrial developments are progressing rapidly. Such an industrial development stores semiconductor information in a very small area, processes a large amount of information in a short time, and plays an important role in displaying processed information. This is accelerating due to the improvement in performance of semiconductor products such as liquid crystal display devices.
이와 같이 타 산업에 많은 영향을 미치는 반도체 제품은 매우 정밀한 반도체 공정을 반복적으로 진행한 후 생산되는데 이는 반도체 제품의 이동이 매우 빈번하게 발생됨을 의미한다.As described above, semiconductor products having a large influence on other industries are produced after repeating highly precise semiconductor processes, which means that the movement of semiconductor products occurs very frequently.
이처럼 빈번한 이동이 발생되는 반도체 제품을 신속 정확하게 원하는 목적지로 이송하기 위하여 최근 무인 자동 반송 대차(Auto Gudied Vehicle;AGV)가 보급되고 있다.In order to transfer such a frequently occurring semiconductor product to a desired destination quickly and accurately, an unmanned automatic vehicle transfer (AGV) has recently been popularized.
그러나, 무인 자동 반송 대차가 다운 되거나 설비 이상을 일으켜 고유의 작업을 수행하지 못하거나, 무인 자동 반송 대차의 적용이 어려운 반도체 공정 등에서는 무인 자동 반송 대차를 대신하여 수동 대차(Manual Guided Vehicle)가 사용될 수 밖에 없다.However, in a semiconductor process where the unmanned automatic transfer truck is down or due to a malfunction of the equipment, or a semiconductor process in which the unmanned automatic transfer truck is difficult to apply, a manual guided vehicle is used instead of the unmanned automatic transfer truck. There is no choice but to.

The ability to lift is desperately needed.
본 고안은 이와 같은 요구에 부응한 것으로써, 본 고안의 목적은 중량이 매우 무거운 반도체 제품이 수동대차에 적재된 상태에서 작업자가 반도체 제품을 수동 대차의 상면으로부터 원하는 높이만큼 리프트 시킬 수 있도록 함에 있다.The present invention satisfies this need, and an object of the present invention is to allow a worker to lift a semiconductor product from a top surface of a manual bogie to a desired height in a state where a very heavy semiconductor product is loaded on a manual bogie. .
본 고안의 다른 목적은 반도체 제품을 리프트 시킬 때 작업자가 최소의 힘으로 반도체 제품을 원하는 높이 만큼 리프트 시킬 수 있도록 함에 있다.Another object of the present invention is to allow a worker to lift a semiconductor product to a desired height with minimal force when lifting the semiconductor product.

한편, 크로스 링크(473)의 위쪽 2 개의 단부중 어느 하나는 지지 플레이트(450)의 밑면에 고정된 제 2 힌지 블록(479a)에 다시 힌지 결합되고, 크로스 링크(473)의 위쪽 2 개의 단부중 나머지 단부는 지지 플레이트(450)의 밑면에 고정된 슬라이더(478)에 힌지 결합된다.On the other hand, any one of the two upper ends of the cross link 473 is hinged again to the second hinge block 479a fixed to the underside of the support plate 450, and among the two upper ends of the cross link 473. The other end is hinged to the slider 478 fixed to the bottom of the support plate 450.
슬라이더(478)는 크로스 링크(473)의 아래쪽 2 개의 단부가 리드스크류 장치(465)의 이송 부싱(463)이 움직이면서 단부와 단부의 사이 간격이 좁아짐에 따라 크로스 링크(473)의 위쪽 2 개의 단부와 단부의 사이 간격이 연동되어 좁아질 때, 단부의 변위를 수용할 수 있도록 하기 위함으로 이를 구현하기 위해서는 지지 플레이트(450)의 밑면에 설치되고, 슬라이더(478)의 내부에는 베어링이 장착된 크로스 링크(473)의 단부가 설치되어 지지된다.The slider 478 has two lower ends of the cross link 473 as the feed bushing 463 of the lead screw device 465 moves so that the gap between the ends and the ends narrows between the upper two ends of the cross link 473. When the gap between the end and the end is narrowed, in order to accommodate the displacement of the end in order to implement this, it is installed on the bottom of the support plate 450, the inside of the slider 478 cross bearing mounted An end of the link 473 is provided and supported.
이와 같이 크로스 링크(473)를 설치하더라도 크로스 링크(473)가 무거운 하중을 받을 경우 크로스 링크(473)의 좌우 흔들림이 크게 발생하여 지지되는 반도체 제품의 이송 안전성이 크게 저하된다.Even if the cross link 473 is provided in this way, when the cross link 473 receives a heavy load, the left and right shakes of the cross link 473 are greatly generated, and the transport safety of the semiconductor product supported is greatly reduced.
이를 극복하기 위하여 지지 플레이트(450)의 4 개의 모서리에는 복수개의 관통공(미도시)이 형성되고, 관통공에는 지지 폴(452)이 삽입된 후 지지 폴(452)의 아래쪽 단부는 수동대차 본체(700)의 내측 바닥면에 고정된다. 이로써 크로스 링크(473)의 좌우 흔들림이 대폭 감소될 수 있다.In order to overcome this, a plurality of through holes (not shown) are formed at four corners of the support plate 450, and the support poles 452 are inserted into the through holes, and then the lower end of the support poles 452 is a manual bogie body. It is fixed to the inner bottom surface of 700. This can greatly reduce the left and right shake of the cross link 473.
한편, 수동 대차로 이송할 대부분의 반도체 제품은 비교적 경량이지만, 경우에 따라서 50kg 이상의 중량을 갖는 액정표시패널과 같은 반도체 제품을 수동대차로 이송할 때, 작업자가 리드스크류 장치(465)와 구동장치(460)만으로는 무거운 하중의 반도체 제품을 일정 높이 리프트 시킬 때 많은 힘을 필요로 하는 문제점이 있다.On the other hand, most of the semiconductor products to be transferred to the manual bogie is relatively light weight, but in some cases, when the user transfers a semiconductor product, such as a liquid crystal display panel having a weight of 50kg or more to the manual bogie, the operator is the lead screw device 465 and the driving device 460 alone has a problem that requires a lot of force when lifting a heavy load of a semiconductor product a certain height.
본 고안에서는 이와 같은 문제점을 극복하기 위하여 수동대차 몸체(700)의 내부 바닥에 보조 리프트 유닛(490)이 설치된다.In the present invention, the auxiliary lift unit 490 is installed on the inner bottom of the manual bogie body 700 in order to overcome such a problem.
보조 리프트 유닛(490)은 실린더 몸체(491)와 실린더 로드(492)로 구성된 유체 실린더가 사용된다. 이때, 유체 실린더의 작동 유체로는 다양한 물성을 갖는 유체가 사용될 수 있지만, 본 고안에서는 바람직한 일실시예로 가스를 작동 유체로 사용하기로 한다.The auxiliary lift unit 490 uses a fluid cylinder composed of a cylinder body 491 and a cylinder rod 492. In this case, a fluid having various physical properties may be used as the working fluid of the fluid cylinder, but in the present invention, a gas is used as the working fluid in a preferred embodiment.
이때, 실린더 몸체(491)는 수동대차 몸체(700)의 내부 바닥에 설치되며 바람직하게 크로스 링크(473)의 내부에 설치되도록 한다.At this time, the cylinder body 491 is installed on the inner bottom of the manual bogie body 700 and is preferably installed inside the cross link 473.
실린더 몸체(491)에 설치되어 작동되는 실린더 로드(492)는 지지 플레이트(450)의 단부에 단순 접촉된다. 이때, 실린더 로드(492)의 단부에는 지지 플레이트(450)와 부드러운 접촉을 위하여 러버(rubber)와 같은 완충 물질을 설치하는 것이 바람직하다.The cylinder rod 492 installed and operated in the cylinder body 491 is simply in contact with the end of the support plate 450. In this case, it is preferable to install a cushioning material such as a rubber at the end of the cylinder rod 492 for smooth contact with the support plate 450.
이와 같은 구성을 갖는 보조 리프트 유닛(490)은 지지 플레이트(450)에 무거운 반도체 제품이 로딩된 상태에서 작업자가 크로스 링크(473)를 리프트 시키기 위하여 핸들(486b)을 돌릴때, 크로스 링크(473)의 업-다운을 서포트하여 작업자가 보다 적은 힘으로 지지 플레이트(450)에 안착된 반도체 제품이 리프트 되도록 하는 역할을 한다.The auxiliary lift unit 490 having such a configuration has a cross link 473 when the operator rotates the handle 486b to lift the cross link 473 while a heavy semiconductor product is loaded on the support plate 450. By supporting the up-down of the operator serves to lift the semiconductor product seated on the support plate 450 with less force.
앞서 상세하게 설명한 본 고안에 의하면, 수동대차에 적재된 무거운 중량의 반도체 제품을 전기적인 에너지 없이 원하는 높이 만큼 이격시킬 수 있으며, 반도체 제품을 원하는 높이 만큼 이격시킬 때 필요한 힘을 최소화하여 작업자의 피로도를 크게 경감시킴은 물론 작업자가 무리한 힘으로 반도체 제품을 이송할 때 발생하는 운반 안정성 저하를 방지하는 효과가 있다.According to the present invention described in detail above, it is possible to separate the heavy weight semiconductor products loaded on the manual cart by the desired height without electrical energy, and to minimize the force required to separate the semiconductor products by the desired height to reduce the fatigue of the operator In addition to reducing significantly, there is an effect of preventing a reduction in transport stability that occurs when the operator transfers the semiconductor product with excessive force.
