에칭장치Etching Equipment

본 발명은 엘리베이터의 케이지와 도어 그리고, 건축물의 장식용등으로 널리 사용되는 스텐레스판이나 동판 등의 금속판(이하, 금속판이라 통칭함)의 표면에 에칭(etching)가공을 하여 금속판의 표면에 아름다운 무늬를 형성할 수 있도록 하는 에칭장치에 관한 것이다.The present invention provides a beautiful pattern on the surface of the metal plate by etching the surface of the metal plate (hereinafter referred to as metal plate) such as stainless steel plate or copper plate which is widely used for decoration of elevator cages and doors and buildings. It relates to an etching apparatus that can be formed.

종래의 에칭방법은 콘크리트로 깊게 구축한 에칭용액탱크의 내측에 에칭용액을 채운뒤에 가공할 금속판을 "+"전극에 걸은 상태에서 에칭용액의 내측에 침지(沈漬)하고, "-"전극도 에칭용액의 내측에 침지시킨 상태에서 전류를 통과시키면 금속판의 표면이 부식되면서 에칭면을 형성하게 된다.In the conventional etching method, the etching solution is filled in the inside of the etching solution tank deeply constructed of concrete, and the metal plate to be processed is immersed inside the etching solution while the metal plate to be processed is hooked on the "+" electrode. When a current is passed while being immersed inside the etching solution, the surface of the metal plate is corroded to form an etching surface.

이와 같은 종래의 에칭방법은, "+"전극에 가공할 금속판을 걸기 위하여 금속판에 구멍을 뚫어야만 했고, 상기와 같이 금속판에 "+"전극에 걸기위한 구멍이 뚫려 있어서 에칭가공이 완료한 뒤에 상기 구멍을 뚫었던 부분을 잘라내야 했다.In the conventional etching method, a hole must be drilled in the metal plate to hang the metal plate to be machined on the "+" electrode, and as described above, the hole for hanging the "+" electrode is drilled in the metal plate. I had to cut out the hole that I drilled.

이하 상기한 바와 같은 본 발명 실시예의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the embodiment of the present invention as described above as follows.

먼저, 금속판(13)에 임의의 문양을 에칭을 하고자 할 결우에는 에칭할 부분을 제외한 나머지 부분에 약품을 도포한다. 이와같이 하면 상기 약품이 도포된 부분에서는 에칭이 발생하지 않고, 약품이 도포되지 않은 부분만 에칭이 되는 것이다. 상기와 같이 한후, 상기 금속판(13)을 에칭용액(12)이 담겨져 있는 에칭용액탱크(2)의 내측바닥면에 눕혀 놓은다. 이때, 상기 +전극봉(5)과 금속판(13)을 전기적으로 연결되게 한다.First, in the case where a desired pattern is to be etched on the metal plate 13, a chemical is applied to the remaining portions except for the portion to be etched. In this way, etching does not occur in the portion where the chemical is applied, and only the portion where the chemical is not applied is etched. After the above, the metal plate 13 is laid on the inner bottom surface of the etching solution tank 2 in which the etching solution 12 is contained. At this time, the + electrode 5 and the metal plate 13 to be electrically connected.

그 뒤, 실린더(11)의 로드(11`)가 돌출되도록 실린더(11)를 작동시키게 되면, 덮개형전극판(8)은 힌지부(9)를 중심으로 회동하면서 에칭용액탱크(2)의 상측에 닫혀 지게 된다.Then, when the cylinder 11 is operated so that the rod 11 ′ of the cylinder 11 protrudes, the lid-shaped electrode plate 8 rotates about the hinge portion 9, so that the etching solution tank 2 is closed. It is closed on the upper side.

이 때, 상기 덮개형전극판(8)의 양측에 외향돌출된 걸림돌기(10)가 에칭용액탱크(2)의 상부양측에 단턱지게 형성된 걸림턱(3)에 걸려서 더 이상 하강하지 않고 정확한 위치에 놓이게 된다.At this time, the locking projections 10 protruding outwardly on both sides of the lid-shaped electrode plate 8 are caught by the locking projections 3 formed on both sides of the upper portion of the etching solution tank 2 so that they are not lowered anymore. Will be placed in.

상기와 같이 덮개형전극판(8)이 에칭용액탱크(2)의 상측에 닫혀지게 되면, 덮개형전극판(8)의 저면에 하향 돌출된 침지전극판(14)이 에칭용액(12)에 침지되게 되면서 침지전극판(14)에 흐르고 있는 -전극과, +전극봉(5)의 +전극이 에칭용액(12)에 의해 통전되게 되어 상기 금속판(13) 중 약품이 묻지 않은 부분만 부식되면서 에칭면을 형성하게 된다.When the lid-type electrode plate 8 is closed on the upper side of the etching solution tank 2 as described above, the immersion electrode plate 14 protruding downward on the bottom surface of the lid-type electrode plate 8 is applied to the etching solution 12. While being immersed, the -electrode flowing in the immersion electrode plate 14 and the + electrode of the + electrode electrode 5 are energized by the etching solution 12, so that only the portion of the metal plate 13 which is not chemically etched is corroded and etched. It will form a face.

상기와 같이 덮개형전극판(8)을 닫음에 따라 전류가 통전되어 에칭가공이 완료된 뒤에는 실린더(11)를 작동시켜 덮개형전극판(8)이 에칭용액탱크(2)의 상측에서 상측으로 힌지식으로 개방되면, 상기에칭용액(12)에 침지되었던 침지전극판(14)이 에칭용액(12)에서 나와 에칭용액탱크(2)의 내측에는 더이상 전류가 흐를수 없게 된다.As the cover electrode plate 8 is closed as described above, after the current is energized and the etching process is completed, the cylinder 11 is operated to cover the cover electrode plate 8 from the upper side of the etching solution tank 2 to the upper side. When open to the knowledge, the immersion electrode plate 14 that has been immersed in the etching solution 12 exits the etching solution 12 and no more current can flow inside the etching solution tank 2.

상기 덮개형전극판(8)의 저면에 설치되어 있는 침지전극판(14)에는 다수의 통공(15)이 형성되어 있고, 상기 침지전극판(14)이 다수개가 일정간격으로 배열설치되어서 덮개형전극판(8)을 상측으로 개방시 침지전극판(14)에 묻어있던 에칭용액(13)이 상기 다수의통공(15)과 인접한 침지전극판(14)사이의 틈새를 통해 하측으로 흘러 내리게 된다.A plurality of through holes 15 are formed in the immersion electrode plate 14 provided on the bottom of the cover electrode plate 8, and the plurality of immersion electrode plates 14 are arranged at regular intervals to cover the cover type. When the electrode plate 8 is opened upward, the etching solution 13 buried in the immersion electrode plate 14 flows downward through a gap between the plurality of through holes 15 and the adjacent immersion electrode plate 14. .

상기와 같이 덮개형전극판(8)이 상측으로 개방된 뒤에는 에칭용액탱크(2)의 바닥면에 눕혀져 있는 금속판(13)을 꺼내어 금속판(13)에 묻어 있는 에칭용액(12)을 세척을 하고, 이렇게 에칭용액(12)을 세척한 금속(13)판의 에칭면에 금박이나 은박, 에폭시 등을 코딩시켜서 장식판재를 제조하게 되는 것이다.After the cover electrode plate 8 is opened as described above, the metal plate 13 lying on the bottom surface of the etching solution tank 2 is taken out, and the etching solution 12 buried in the metal plate 13 is washed. In this way, a gold plate, silver foil, epoxy or the like is coded on the etching surface of the metal 13 plate from which the etching solution 12 is washed, thereby producing a decorative plate material.

그리고, 본 발명의 에칭장치를 사용하지 않을 경우에는 메인전원을 차단시킨 상태에서 덮개형전극판(8)을 닫아두면 에칭용액(12)의 냄새가 작업장으로 새어나가는 것을 방지하고, 이물질이 에칭용앵탱크(2)의 내측으로 들어가는 것을 차단하며, 에칭용액에 사람이 빠질 염려가 없게 되는 등의 효과가 있는 것이다.In the case where the etching apparatus of the present invention is not used, closing the lid-type electrode plate 8 while the main power is cut off prevents the smell of the etching solution 12 from leaking into the work place, and prevents foreign substances from being etched. It blocks the entry into the tank 2, and there is an effect that the etching solution is not likely to fall out.

이상에서 살펴본 바와 같은 본 발명에 따른 에칭장치는, 에칭용액탱크의 내측에 에칭가공할 금속판을 눕혀 놓은 상태에서 에칭가공이 이루어 질수 있도록 되어서, 종래와는 달리 금속판에 구멍을 뚫지 않아도 되므로 불필요한 작업공정을 삭제시키는 효과와, 금속판의 손실이 발생하지 않는 효과와, 소량의 에칭용액으로 에칭가공을 있는 등의 장점을 지니고 있는 것이다.As described above, the etching apparatus according to the present invention can be etched in a state in which a metal plate to be etched is placed inside an etching solution tank, so unlike the conventional art, it is not necessary to drill a hole in the metal plate, thereby unnecessary work process. And the effect of eliminating the loss of the metal plate, the effect of eliminating the loss of the metal plate, and the etching process with a small amount of the etching solution.

상기와 같이 불필요한 작업공정이 삭제되고, 금속판의 손실을 방지하며, 소량의 에칭용액으로 에칭가공을 할 수 있는 등의 장점으로 인하여 제품 생산원가가 대폭절감되는 효과를 지니고 있으며, 인체에 유해한 에칭용액이 담겨져 있는 에칭용액탱크를 덮개형전극판으로서 덮어 둘 수 있슴으로해서 작업자가 에칭용액탱크에 빠지는 등의 안전사고를 완벽하게 예방할 수 있는 효과를 지니고 있는 것이다.This eliminates unnecessary work processes as described above, prevents the loss of metal plates, and enables the etching process with a small amount of etching solution, which greatly reduces the production cost of the product.
