본 발명은 휴대전화기 등 전자제품의 케이스 등으로 사용하는 알루미늄이나 스테인리스강 등의 소재로 된 금속판재의 표면을 다수의 미세한 헤어라인으로 연마가공하기 위하여 연마포가 형성된 연마벨트(4)를 회전롤러(3)에 의하여 원형으로 회전시켜 연마가공하는 헤어라인 연마기에 관한 것이다.The present invention is a rotating roller for rotating the polishing belt (4) formed with a polishing cloth in order to polish the surface of a metal plate made of a material such as aluminum or stainless steel used in a case of an electronic product such as a mobile phone with a plurality of fine hairline It relates to a hairline polishing machine which rotates in a circular shape and grinds by (3).

종래의 기술은 도 6에서와 같이 연마벨트(4)가 양측에 설치된 2개의 회전롤 러(3)만으로 지지되어 연마벨트(4)가 수평방향으로 평행한 원형궤도로 회전되는 구성이므로 연마벨트(4)의 늘어짐을 방지하는 장치가 없어서 연마벨트(4)의 늘어지는 현상에 의하여 가공물(10)의 측단부가 중앙부분보다 많이 연마되어 가공면이 평활하지 못한 단점이 있었다.In the prior art, as shown in FIG. 6, the polishing belt 4 is supported by only two rotary rollers 3 installed on both sides thereof, so that the polishing belt 4 is rotated in a circular orbit parallel to the horizontal direction. There is no device to prevent the sagging of 4) due to the phenomenon of sagging of the polishing belt 4, the side end portion of the workpiece 10 was polished more than the center portion, there was a disadvantage that the processing surface was not smooth.

이를 개선하기 위하여 본 발명에서는 연마벨트(4)를 회전시키는 양측의 회전롤러(3) 이외로 상측에 텐션롤러(11)를 추가로 설치하여 연마벨트(4)가 세모꼴로 회전되도록 구성하고 연마벨트(4)의 세모꼴로 회전되는 회전궤도 내측에서 외측으로 연속적으로 가압할 수 있는 코일스프링(12)을 설치하여 코일스프링(12)의 가압으로 상측에 있는 텐션롤러(11)를 밀어올려 연마벨트(4)의 장력을 팽팽하게 유지시켜 가공물(10)의 표면에 평활한 헤어라인이 가공될 수 있도록 구성한 것이다.In order to improve this, in the present invention, the tension belt 11 is additionally installed in addition to the rotary rollers 3 on both sides for rotating the polishing belt 4, so that the polishing belt 4 is rotated in a triangular shape and the polishing belt is (4) Install the coil spring 12 which can continuously press the inner side of the rotating trajectory rotated in the triangular shape, and push the tension roller 11 on the upper side by the pressure of the coil spring 12 to raise the polishing belt ( The tension of 4) is maintained to be configured so that a smooth hairline can be processed on the surface of the workpiece 10.

일반적으로 “헤어라인”이라 함은 전자제품의 외장으로 사용되는 알루미늄이나 스테인리스강 같은 금속판재의 표면에 무수히 많은 미세한 가는 선을 긋는 작업을 지칭하는 것으로 금속 특유의 광택으로 인한 눈부심을 방지하고, 제품을 만지면 묻는 지문을 방지하며, 제품의 단조로움을 탈피하여 고급스러움을 더 하도록 하는 것이다. In general, "hairline" refers to the work of drawing a myriad of fine thin lines on the surface of a metal plate such as aluminum or stainless steel, which is used as an exterior of an electronic product, to prevent glare caused by the unique gloss of metal. This prevents fingerprints from touching, and adds luxury by removing the monotony of the product.

이러한 헤어라인의 가공은 강철브러쉬나 연마포 등을 이용하여 금속표면에 직선상의 미세한 헤어라인을 성형하게 되는 것으로서, 종래의 기술은 도 5에서와 같이 연마벨트(4)가 2개의 회전롤러(3)에 의하여 수평방향으로 평행한 회전궤도를 이루면서 회전하여 금속판재의 표면에 헤어라인을 가공하는 헤어라안 연마기가 사용되었다.The processing of such hairline is to form a fine hairline in a straight line on the metal surface using a steel brush or abrasive cloth, the conventional technique is that the polishing belt (4) has two rotary rollers (3) as shown in FIG. The hairan grinder is used to rotate a horizontal orbit in parallel to form a hairline on the surface of the metal sheet.

이러한 헤어라인 연마기는 연마프레임(2)의 양 끝에 구동모터로 회전되는 회전롤러(3)를 각각 구성하고, 이 회전롤러(3)사이에 연마포와 같은 연마벨트(4)를 연결하여 이 연마벨트(4)를 회전시켜 가공물(10)에 맞닿도록 하여 헤어라인가공을 하도록 구성하였다.Such a hairline polishing machine constitutes a rotary roller 3 which is rotated by a driving motor at both ends of the polishing frame 2, and connects the polishing belt 4, such as a polishing cloth, between the rotating rollers 3 to make this polishing. The belt 4 was rotated so as to contact the workpiece 10 to perform hairline processing.

그러나 이와 같은 종래의 연마기는 연마벨트(4)의 장력이 점차 느슨해지는 문제로 인하여 수시로 장력을 점검해야 하고,However, such a conventional polishing machine has to check the tension from time to time due to the problem that the tension of the polishing belt 4 is gradually loosened,

장력이 느슨해 지면 연마벨트(4)가 밑으로 늘어져서 결과적으로 가공물(10)의 양쪽 끝단이 많이 연마되므로 표면이 평활한 가공물(10)을 얻을 수가 없어 제품의 품질이 떨어지고 불량이 발생하는 문제가 있었고,When the tension is loosened, the abrasive belt 4 is stretched downward, and as a result, both ends of the workpiece 10 are polished a lot, so that the workpiece 10 having a smooth surface cannot be obtained. ,

연마벨트(4)는 회전롤러(3) 사이에 일정한 장력으로 연결되어 있기 때문에 연마벨트(4)의 교체 등을 위하여 연마벨트(4)를 회전롤러(3)에서 빼내거나 다시 장착하기가 힘들기 때문에 유지 보수에 많은 어려움이 있었다.Since the abrasive belt 4 is connected to the rotary rollers 3 with a constant tension, it is difficult to remove or refit the abrasive belt 4 from the rotary roller 3 to replace the abrasive belt 4 or the like. Because of this, there were many difficulties in maintenance.

또한 회전하는 연마벨트(4)에 가공물(10)이 연마될 때 항상 가공물(10)이 동일한 위치에 위치하여 연마벨트(4)에 의해 연마되기 때문에 연마벨트(4)의 특정 부분만 수명이 짧아지는 문제가 있었다. In addition, when the workpiece 10 is polished to the rotating abrasive belt 4, the workpiece 10 is always located at the same position and is polished by the abrasive belt 4, so that only a specific part of the abrasive belt 4 has a short lifespan. There was a problem losing.

본 발명은 상기의 문제점을 감안하여 개발한 것으로 연마벨트(4)가 항상 팽팽한 장력을 유지하여 가공물(10)의 표면에 헤어라인이 균일하게 연마된 가공물(10)을 생산할 수 있을 뿐만 아니라, The present invention was developed in view of the above problems, the abrasive belt 4 can always produce a workpiece 10, the hairline is uniformly polished on the surface of the workpiece 10 by maintaining a tight tension,

유지 보수에 있어서, 연마벨트(4)를 간단하게 교체하기 위하여 연마벨트(4)의 장력을 간편하게 해제시킬 수 있도록 구성하고,In maintenance, in order to easily replace the polishing belt (4) is configured to easily release the tension of the polishing belt (4),

가공물(10)이 연마되는 위치를 수시로 변경하여 연마벨트(10)가 전체적으로 고르게 닳도록 한 헤어라인 연마기를 제공하는데 그 목적이 있다.It is an object of the present invention to provide a hairline polishing machine in which the position at which the workpiece 10 is polished is changed from time to time so that the polishing belt 10 is uniformly worn out.

이상과 같은 본 발명을 좀 더 자세히 설명하면 다음과 같다.When explaining the present invention in more detail as follows.

도 1 내지 도 4에서와 같이 헤어라인 연마기(1)는 하부에 가공물(10)을 전후로 이송하여 가공물(10)이 연마벨트(4)의 위치에 놓여질 수 있도록 전후이송프레임(6)이 구성되며, 상부에는 가공물(10)에 헤어라인을 가공하는 연마벨트(4)를 지지하여 회전시키는 회전롤러(3)를 지지하는 연마프레임(2)이 구성된다.As shown in FIGS. 1 to 4, the hairline polishing machine 1 is configured to transfer the workpiece 10 to the lower portion back and forth so that the workpiece 10 may be placed at the position of the polishing belt 4. In the upper part, the polishing frame 2 supporting the rotating roller 3 for supporting and rotating the polishing belt 4 for processing the hairline on the workpiece 10 is configured.

전후이송프레임(6)은 상하이송에어실린더(8)에 고정된 이송레일(17)위에서 전후방향으로 슬라이딩 이송되도록 구성되어 있으며 이러한 모든 작동제어는 공지된 컨트롤러 및 각종센서 등에 의하여 작업조건에 따라 다양하게 작동할 수 있는 것으로서,The front and rear transfer frame 6 is configured to slide forward and backward on the transfer rail 17 fixed to the Shanghai Song Air Cylinder 8, and all these operation controls vary according to working conditions by a known controller and various sensors. As it can work,

이러한 작동제어시스템에 의하여 가공물(10)이 고정된 고정대(7)를 연마벨트(4)의 하부로 이송한 후, 상하이송에어실린더(8)에 의하여 고정대(7)에 고정된 가공물(10)을 상하이송시켜 가공물(10)의 표면이 연마벨트(4)에 맞닿게 하여 가공물(10)의 표면에 헤어라인가공이 되도록 한다.The workpiece 10 fixed to the holder 7 by the Shanghai Song Air Cylinder 8 after transferring the holder 7 on which the workpiece 10 is fixed by the operation control system to the lower portion of the polishing belt 4. Shanghai is sent so that the surface of the workpiece 10 abuts the abrasive belt 4 so that the surface of the workpiece 10 is subjected to hairline processing.

연마프레임(2)은 회전롤러(3) 및 텐션롤러(11)에 끼워진 연마벨트(4)가 일정한 장력을 유지한 채 회전하도록 구성되는 것으로,The polishing frame 2 is configured such that the polishing belt 4 fitted to the rotary roller 3 and the tension roller 11 rotates while maintaining a constant tension.

연마프레임(2)의 양 끝단에 각각 회전롤러(3)를 구성하고 연마프레임(2)의 상부에 텐션롤러고정대(16)에 의해 고정된 텐션롤러(11)를 구성한다. 상기 회전롤러(3) 및 텐션롤러(11)에 연마벨트(4)를 끼워 연결하여 구동모터에 의해 회전시킨다.A rotating roller 3 is formed at both ends of the polishing frame 2, and a tension roller 11 fixed by the tension roller fixing rod 16 is formed on the polishing frame 2, respectively. The abrasive belt 4 is connected to the rotary roller 3 and the tension roller 11 to be rotated by a driving motor.

텐션롤러고정대(16)의 하단에 고정된 승강봉(15)이 연마프레임(2)의 상판을 관통하여 코일스프링덮개판(13)에 고정된다. 코일스프링덮개판(13)의 하면과 연마프레임(2)의 하판 사이에는 고탄성의 코일스프링(12)이 구성되며, 연마프레임(2)의 상판과 코일스프링덮개판(13)의 사이에는 에어실린더(14)가 구성된다.The lifting bar 15 fixed to the lower end of the tension roller holder 16 is fixed to the coil spring cover plate 13 through the upper plate of the polishing frame 2. A highly elastic coil spring 12 is formed between the lower surface of the coil spring cover plate 13 and the lower plate of the polishing frame 2, and an air cylinder is provided between the upper plate of the polishing frame 2 and the coil spring cover plate 13. 14 is configured.

상기 에어실린더(14)는 공압을 제거할 경우 에어실린더(14) 내부의 압력이 소실되어 코일스프링(12)이 자유롭게 상측으로 팽창할 수 있다.When the air cylinder 14 is removed from the air pressure, the pressure inside the air cylinder 14 is lost, so that the coil spring 12 can freely expand upward.

코일스프링(12)의 탄성을 받는 코일스프링덮개판(13)에 고정된 승강봉(15)으로 텐션롤러고정대(16)에 고정된 텐션롤러(11)를 상부로 밀어 올리므로 회전롤러(3) 및 텐션롤러(11)에 끼워진 연마벨트(4)는 항상 일정한 장력을 유지하게 된다.As the lifting roller 15 fixed to the coil spring cover plate 13 receiving the elasticity of the coil spring 12 pushes the tension roller 11 fixed to the tension roller holder 16 upwards, thereby rotating the roller 3. And the polishing belt (4) fitted to the tension roller 11 will always maintain a constant tension.

따라서, 구동모터로 회전롤러(3) 또는 텐션롤러(11)를 구동하여 연마벨트(4)를 회전시킨 후, 전후이송프레임(6)의 고정대(7)에 고정된 가공물(10)을 이송하여 가공물(10)의 표면을 연마벨트(4)에 맞닿게 하면 장력이 유지된 연마벨트(4)는 눌리거나 휘지않고 항상 팽팽하게 장력이 유지되므로, 팽팽한 연마벨트(4)의 연마면에 맞닿는 가공물(10)의 표면은 평활한 헤어라인이 연마될 수 있는 것이다.Therefore, the rotary belt 3 or the tension roller 11 is driven by the drive motor to rotate the polishing belt 4, and then the workpiece 10 fixed to the holder 7 of the front and rear transfer frame 6 is transferred. When the surface of the workpiece 10 is brought into contact with the polishing belt 4, the tensioned abrasive belt 4 is always tensioned without being pressed or bent, so that the workpiece is in contact with the polishing surface of the tensioned abrasive belt 4 The surface of (10) is a smooth hairline can be polished.

또한, 도 2 및 도 4에서와 같이 연마벨트(4)를 교체하기 위하여 에어실린더(14)로서 코일스프링덮개판(13)을 눌러주면 코일스프링덮개판(13)이 코일스프 링(12)을 압축하면서 하측으로 이동되고 이에 따라 코일스프링덮개판(13)에 고정된 승강봉(15)에 연결된 텐션롤러고정대(16)가 하측으로 이동되고, 이에 따라 텐션롤러고정대(16)에 연결된 텐션롤러(11)가 하측으로 이동되어 회전롤러(3)와 텐션롤러(11)에 끼워진 연마벨트(4)가 헐거워지게 되므로 연마벨트(4)를 쉽게 교체할 수 있으며,In addition, as shown in FIGS. 2 and 4, when the coil spring cover plate 13 is pressed with the air cylinder 14 to replace the polishing belt 4, the coil spring cover plate 13 is connected to the coil spring 12. The tension roller fixing rod 16 connected to the lifting bar 15 fixed to the coil spring cover plate 13 is moved downward while compressing, and thus the tension roller connected to the tension roller fixing rod 16 is moved. 11) is moved downward so that the abrasive belt (4) fitted to the rotary roller (3) and the tension roller (11) is loose, so that the abrasive belt (4) can be easily replaced,

에어실린더(14)의 공기압력을 해제하면 눌려있던 코일스프링(12)이 복원되면서 스프링의 팽창력이 승강봉(15)을 통하여 텐션롤러(11)를 밀어올리므로 연마벨트(4)에 장력이 발생되어 가공면이 평활한 헤어라인 연마가공을 하게 되는 것이다.When the air pressure of the air cylinder 14 is released, the coil spring 12 that is pressed is restored and the expansion force of the spring pushes the tension roller 11 through the elevating rod 15 so that tension is generated in the polishing belt 4. Therefore, the processing surface is a smooth hairline polishing process.

또한 본 발명은 도 5에서와 같이 이송레일(17)에 의해 전후로 미끄럼 이동되는 전후이송프레임(6)의 상부에 가공물(10)을 고정하는 고정대(7)를 구성하고,In addition, the present invention constitutes a holder (7) for fixing the workpiece 10 on the upper portion of the front and rear transfer frame 6 which is slid back and forth by the transfer rail 17, as shown in FIG.

이송레일(17)의 하부에 상하이송에어실린더(8)와 전후이송프레임(6) 후측에 전후이송에어실린더(9)를 구성한다.The forward and backward transfer air cylinders 9 are formed at the rear of the forward transfer frame 6 and the Shanghai transfer air cylinder 8 at the lower portion of the transfer rail 17.

이러한 본 발명은 가공물(10)을 고정대(7)에 고정하고 상하이송에어실린더(8)를 작동하여 가공물(10)이 연마벨트(4)에 맞닿게 하고, In the present invention, the workpiece 10 is fixed to the holder 7 and the Shanghai Song Air Cylinder 8 is operated to bring the workpiece 10 into contact with the polishing belt 4,

전후이송에어실린더(9)로 고정대(7)가 연마벨트(4)의 폭을 벗어나지 않을 정도로 전후이송프레임(6)의 위치를 다양하게 변화하여 위치시킨다.The position of the front and rear transfer frame 6 is varied by positioning the front and rear transfer air cylinder 9 so that the holder 7 does not deviate from the width of the polishing belt 4.

따라서 가공물(10)이 연마벨트(4)의 다양한 면에 연마 되므로 결과적으로 연마벨트(4)가 고르게 닳아 연마벨트(4)의 수명이 연장된다.Therefore, the workpiece 10 is polished on various surfaces of the abrasive belt 4, and as a result, the abrasive belt 4 is evenly worn and thus the life of the abrasive belt 4 is extended.
