Description

안경렌즈 제조용 몰드의 이동거리 셋팅장치{omitted}Moving distance setting device of mold for manufacturing spectacle lens {omitted}

본 발명은 플라스틱 안경렌즈를 제조하기 위하여 두개의 몰드를 렌즈의 중심두께만큼 이격시킨 후 몰드 외측을 테이프로 감아주는 장치에 있어서, 유리몰드의 중앙부위 이격거리를 정확히 셋팅시켜 주므로써 몰드에 의해 제조되는 안경렌즈의 중심두께를 일치시켜 주도록 하는 안경렌즈 제조용 몰드의 이동거리 셋팅 장치에 관한 것이다.In the present invention, in order to manufacture a plastic spectacle lens, the two molds are spaced apart by the center thickness of the lens, and then wound around the outside of the mold with a tape, by setting the distance of the center portion of the glass mold precisely manufactured by the mold It relates to a moving distance setting device of the mold for manufacturing the spectacle lens to match the center thickness of the spectacle lens.

기존의 플라스틱 안경렌즈를 제조하기 위해서는 두개의 유리로 된 몰드를 수지로 된 가스켓에 렌즈의 가장자리 두께(측면 두께)에 맞춰 끼운 후 몰드 사이에 모노머를 주입시키고 모노머가 경화되면 가스켓을 잘라내어 안경렌즈를 제조하고 있다.In order to manufacture a conventional plastic spectacle lens, two glass molds are inserted into a resin gasket in accordance with the edge thickness (side thickness) of the lens, and monomer is injected between the molds. Manufacture.

이보다 개량 된 방법으로는 두개의 몰드를 렌즈의 측면두께에 맞추어 이격시킨 상태에서 몰드의 외측을 테이프로 감아준 후 테이프의 일부를 개방시켜 모노머를 주입하고 다시 테이프를 접착시킴으로써 모노머의 경화 후 테이프를 떼내고 몰드를 분리시켜 안경렌즈를 얻어내도록 하고 있다.An improved method is to wind the tape after curing the monomer by winding the outside of the mold with a tape while the two molds are separated by the side thickness of the lens, and then opening a part of the tape. The mold is removed and the mold is separated to obtain the spectacle lens.

그러나 위와같이 몰드의 외측을 테이프로 감아주는 방법은 몰드가 곡면을 갖게 되어 중앙 부위의 이격거리를 맞추기가 어려우므로 몰드의 측면 이격거리를 알아낸후 이를 몰드의 곡률 반경과 연산시킴으로써 몰드사이의 중심두께를 맞추는 방식을 사용하고 있다.However, as the method of winding the outside of the mold with tape as above, it is difficult to match the separation distance of the center part because the mold has a curved surface. Therefore, after determining the side separation distance of the mold and calculating it with the radius of curvature of the mold, the center thickness between molds I'm using a way to fit.

이같이 렌즈의 측면두께에 따라 렌즈의 중심두께를 맞추게 되는 경우 몰드의 측면이 일정하기 않은 이상 렌즈의 중심두께에 오차가 발생할 수 밖에 없다.As such, when the center thickness of the lens is adjusted according to the side thickness of the lens, an error may occur in the center thickness of the lens unless the side of the mold is constant.

특히 몰드의 측면은 날카롭기 때문에 이를 없애주는 면취과정에서 가공오차가 발생하게 되므로 몰드의 측면이 일정하지 않게 되어 몰드의 측면거리를 이용하여 렌즈의 중심두께를 맞추는 것은 오차가 발생할 수 밖에 없는 것이었다.In particular, since the side of the mold is sharp, processing error occurs in the chamfering process to remove it, so that the side of the mold is not constant, and using the side distance of the mold to adjust the center thickness of the lens was inevitably caused an error.

이같이 플라스틱 제조용 몰드의 이격거리 즉 렌즈의 중심두께를 정확히 맞추어 주지 못하여 오차가 발생하는 이유는 몰드의 중앙부 이격거리를 재지 못하고 몰드의 측면 이격거리를 재기 때문에 발생되는 현상으로, 본 발명은 몰드와 몰드 사이에서 몰드의 중앙부 이격거리를 정확히 재주도록 하므로써 몰드에 의해 제조되는 렌즈의 촛점에서 오차를 줄여 주도록 한 것이다.The reason why the error occurs because the distance of the mold for plastic production, that is, the center thickness of the lens cannot be accurately matched, is caused by measuring the side distance of the mold without measuring the center distance of the mold. By precisely measuring the center separation distance between the molds to reduce the error in the focus of the lens produced by the mold.

이러한 본 발명은 렌즈 제조용 몰드가 상하 이동됨에 있어서, 몰드 사이에 측정 수단을 설치하되 상기 측정수단은 전후방으로 이동되게 하고, 몰드의 중심부에 측정수단을 위치시킨 상태에서 몰드를 이동시켜 최근접 거리를 알아낸 후 몰드를 후퇴시켜 측정수단을 빼내고 다시 몰드를 이동시켜 측정수단에 의해 인식된 최근접 거리로부터 중심두께를 뺀만큼의 거리만큼 몰드를 이동시킴으로써 몰드와 몰드 사이의 중앙부 이격거리 즉 렌즈의 중심두께를 정확히 맞추어 줄 수 있도록 한 것이다.In the present invention, when the mold for manufacturing a lens is moved up and down, the measuring means is installed between the molds, but the measuring means is moved back and forth, and the closest distance by moving the mold in a state in which the measuring means is located in the center of the mold. After retrieving, the mold is retracted to remove the measuring means, and the mold is moved again to move the mold by the distance obtained by subtracting the center thickness from the nearest distance recognized by the measuring means. The thickness is precisely matched.

그리고 도시되지는 않았지만 몰드척(24)(25)의 상하 이동과 측정수단(40)의 전후 이동을 제어하는 한편 측정수단(40)에 의해 측정 된 기준점에서 몰드(2)(3)의 이동거리르 계산하여 정확히 중심두께만큼 이동시키는 콘트롤러가 구비된다.Although not shown, the movement distance of the mold 2 and 3 from the reference point measured by the measuring means 40 is controlled while controlling the vertical movement of the mold chucks 24 and 25 and the forward and backward movement of the measuring means 40. It is equipped with a controller that calculates the le and moves it exactly by the center thickness.

본 발명에서 몰드척(24)(25)은 에어공급부(22)(23)를 통하여 진공을 형성시킴으로써 몰드(2)(2)를 고정시키거나 해제시키게 되고 조작봉(20)(21)은 상,하 이동이 가능한 상태로 결합되어지는 한편 타이밍 벨트(30)(31)의 회전시 몰드(2)(3)를 회전시킬 수 있도록 설치된다.In the present invention, the mold chucks 24 and 25 fix or release the molds 2 and 2 by forming a vacuum through the air supply units 22 and 23, and the operating rods 20 and 21 are opened. While being coupled in a state where downward movement is possible, the mold 2 and 3 may be rotated when the timing belts 30 and 31 are rotated.

이때 타이밍벨트(30)(31)는 하나의 모터(32)동력을 축으로 전달하여 회전되게 설치 구성된다.At this time, the timing belts 30 and 31 are configured to rotate by transmitting power of one motor 32 to the shaft.

본 발명의 측정수단(40)은 구조체(41)의 상하부에 각각 센서(42)(42)를 설치한 것으로, 상기 센서(42)(43)는 몰드(2)(3)와 비접촉 방식으로 몰드(2)(3)를 인식하는 비접촉식을 사용하거나 직접 접촉하여 인식하는 접촉식을 사용할 수 있으나 몰드(2)(3)에 흠집을 내지 않는 비접촉식을 사용하는 것이 좋다.Measuring means 40 of the present invention is that the sensor 42, 42 is provided in the upper and lower portions of the structure 41, respectively, the sensor 42, 43 is a mold in a non-contact manner with the mold (2) (3) (2) It is possible to use a non-contact type to recognize (3) or a contact type to recognize by direct contact, but it is preferable to use a non-contact type that does not scratch the mold (2) (3).

상기 측정수단(40)은 이송봉(44)에 결합되어 이송수단(45)에 의해 전후방으로 이송되어지는 것으로 이송수단(45)은 에어 실린더로 구성함이 적합하며, 상기 이송수단(45)은 고정프레임(10)에 고정되거나 별도의 부착물에 고정시킬 수 있는 것으로, 측정수단(40)이 몰드(2)(3)사이로 이송가능하면 된다.The measuring means 40 is coupled to the conveying rod 44 is conveyed back and forth by the conveying means 45 is suitable that the conveying means 45 is composed of an air cylinder, the conveying means 45 is It can be fixed to the fixed frame 10 or to be attached to a separate attachment, the measuring means 40 need only be able to transfer between the mold (2) (3).

이같이 구성된 본 발명의 작동을 살펴본다.It looks at the operation of the present invention configured as described above.

먼저 에어 공급부(22)(23)를 통하여 진공을 형성시킨 상태에서 몰드척(24)(25)에 몰드(2)(3)를 물려주면 몰드(2)(3)는 진공압에 의하여 몰드척(24)(25)에 물려 있게 된다.First, the molds 2 and 3 are passed to the mold chucks 24 and 25 in a state where a vacuum is formed through the air supply units 22 and 23, and the molds 2 and 3 are molded by the vacuum pressure. (24) (25) will be inherited.

이 상태에서 이송수단(45)을 작동시켜 이송봉(44)의 선단에 고정된 측정수단(40)을 몰드(2)(3)의 중앙부에 위치되도록 이송시킨다.In this state, the conveying means 45 is operated to convey the measuring means 40 fixed to the tip of the conveying rod 44 so as to be located at the center of the mold 2, 3.

그리고 서보모터(13)(14)를 작동시키면 이송스크류(15)(16)가 회전하면서 이송프레임(17)(18)을 중앙쪽으로 이동시켜 몰드(2)(3)사이의 거리가 가까워지도록 하고, 몰드(2)(3) 사이의 거리가 가까워져 측정수단(40)에서 몰드(2)(3)를 인식하는 순간 서보 모터(13)(14)의 구동은 정지하고 그때의 거리를 기준점으로 기억하도록 한다.When the servo motors 13 and 14 are operated, the transfer screws 15 and 16 rotate to move the transfer frames 17 and 18 toward the center so that the distance between the molds 2 and 3 is closer. As soon as the distance between the molds 2 and 3 becomes closer and the measuring means 40 recognizes the molds 2 and 3, the driving of the servo motors 13 and 14 stops and the distance is stored as a reference point. Do it.

이때 측성수단(40)의 센서(42)(43)가 비접촉식이냐 접촉식이냐에 따라 몰드(2)(3)가 측정수단(40)에 비접촉되거나 접촉되게 되며, 바람직하게는 비접촉식으로 감지하는 것이 유리몰드(2)(3)에 흠집을 내지 않아 적합하다.At this time, according to whether the sensors 42 and 43 of the measuring means 40 are non-contact or contact type, the molds 2 and 3 are brought into non-contact or contact with the measuring means 40. Preferably, the non-contact sensing is performed. It is suitable because it does not scratch the glass mold (2) (3).

이같이 몰드(2)(3)의 이동 기준점이 기억되면 서보 모터(13)(14)를 역회전시켜 몰드(2)(3) 사이를 벌려주고, 이송수단(45)을 역구동시켜 측정수단(40)을 몰드(2)(2) 사이에서 빼내준다.When the reference point of movement of the molds 2 and 3 is stored as described above, the servo motors 13 and 14 are rotated in reverse to open the molds 2 and 3, and the transfer means 45 is driven back to measure the measurement means ( 40 is pulled out between the molds (2) (2).

그리고 다시 서보 모터(13)(14)를 구동시켜 몰드(2)(3)사이를 가깝게 해주면 측정 수단(40)에 의해 감지된 기준점까지 몰드(2)(3)를 이동시킨 후 제조될 렌즈의 중심두께에 맞추어 몰드(2)(3)를 이동시키게 된다.Then, when the servo motors 13 and 14 are driven again to bring the molds 2 and 3 closer together, the molds 2 and 3 are moved to the reference point detected by the measuring means 40, and then the The molds 2 and 3 are moved in accordance with the center thickness.

여기서 측정수단(40)에 의해 기준점이 잡힌 곳의 몰드(2)(3) 사이거리를 기준거리로 하면 그 기준거리에서 제조할 렌즈의 중심두께를 뺀 거리만큼 몰드(2)(3)를 이동시키면 렌즈의 중심두께를 맞출수 있다.Here, if the distance between the molds (2) and (3) where the reference point is held by the measuring means (40) is the reference distance, the mold (2) (3) is moved by the distance obtained by subtracting the center thickness of the lens to be manufactured from the reference distance. By doing so, you can adjust the center thickness of the lens.

중심두께는 렌즈마다 미리 결정되어지는 것이므로 기준거리가 확인되면 이동거리 계산이 가능하고, 이동거리가 확인되면 서보 모터(13)(14)를 이용하여 정확히 그 이동거리만큼 몰드(2)(3)를 이동시킬 수 있는 것이다.Since the center thickness is determined for each lens in advance, the movement distance can be calculated when the reference distance is confirmed, and when the movement distance is confirmed, the molds 2 and 3 can be precisely moved by the movement distance using the servo motors 13 and 14. You can move it.

이때 측정수단(40)에 의해 몰드(2)(3)의 중앙부 이격 거리를 측정한 기준값에 의해 몰드(2)(3)를 이동시켜 렌즈의 중심두께를 맞추게 되므로 중심두께의 오차가 거의없는 렌즈의 생산이 가능하게 된다.At this time, since the measuring means 40 moves the molds 2 and 3 according to the reference value of the distance between the centers of the molds 2 and 3 to adjust the center thickness of the lens, the lens has almost no error in the center thickness. Production is possible.

중심두께는 렌즈의 도수에 따라 결정되어 지는 것으로 렌즈 제조시 미리 중심두께 거리를 입력시키면 측정수단(40)에 의해 기준점이 잡힐때의 몰드(2)(3) 사이 거리에서 입력된 중심두께 거리를 빼면 몰드(2)(3)가 기준점에서부터 이동하여야 할 거리가 나오게 되고 서보모터(13)(14)에서 계산 된 거리만큼 몰드(2)(3)를 이동시킴으로써 최종적으로 몰드(2)(2)의 중앙부 이격거리가 렌즈의 중심두께가 되도록 한다.The center thickness is determined according to the frequency of the lens. When the center thickness distance is input in advance in manufacturing the lens, the center thickness distance input from the distance between the molds 2 and 3 when the reference point is taken by the measuring means 40 is determined. Subtract the distance that the mold 2 and 3 should move from the reference point and finally move the mold 2 and 3 by the distance calculated by the servomotors 13 and 14. Make sure that the center separation distance is the center thickness of the lens.

이같이 몰드(2)(3)의 중앙부 이격거리가 렌즈의 중심두께가 되게 몰드(2)(3)를 위치시킨 후에는 몰드(2)(3)의 일측에 테이프(4)를 대주고 모터(32)를 작동시키면 타이밍벨트(30)(31)로 조작봉(20)(21)을 회전시켜 몰드(2)(2)를 회전시킴으로써 몰드(2)(3)주위에 테이프(4)가 붙여지게 된다.After positioning the molds 2 and 3 such that the center distance of the molds 2 and 3 becomes the center thickness of the lens, the tape 4 is applied to one side of the molds 2 and 3 and the motor 32 ), The operation belts 20 and 21 are rotated with the timing belts 30 and 31 to rotate the molds 2 and 2 so that the tape 4 is attached around the molds 2 and 3. do.

몰드(2)(3)에 테이프(4)가 붙여지면 몰드척(24)(25)에서 몰드(2)(3)를 분리시킨 후 몰드(2)(3)사이에 모노머를 주입하는 과정을 거쳐 렌즈를 생산하도록 한다.When the tape 4 is attached to the mold 2, 3, the mold chuck 24, 25 separates the mold 2, 3, and then a monomer is injected between the mold 2, 3. To produce the lens.

그 다음에는 다시 몰드척(24)(25)을 상,하 이동시켜 몰드척(24)(25) 사이 거리를 벌려준 후 처음과 같이 몰드(2)(3)를 몰드척(24)(25)에 장착시킴으로써 연속적으로 렌즈를 제조하게 된다.Then, the mold chucks 24 and 25 are moved up and down again to increase the distance between the mold chucks 24 and 25, and then the molds 2 and 3 are moved to the mold chucks 24 and 25 as in the beginning. ) To manufacture the lens continuously.

본 발명은 렌즈 제조시 몰드 중앙부 이격 거리를 렌즈의 중심두께와 정확히 일치되게 맞추어 주므로써 렌즈의 중심두께 오차를 현저히 줄일 수 있어 균일한 품질의 렌즈를 제작할 수 있는 것이다.According to the present invention, the distance between the center portion of the mold is precisely matched with the center thickness of the lens, thereby significantly reducing the center thickness error of the lens, thereby manufacturing a lens of uniform quality.
