Abstract

A method of reconditioning damaged brush shafts is provided to reuse brush shafts to save expenses by repairing bent or worn brush shafts. A method of reconditioning damaged brush shafts includes a first process of inspecting a damaged brush shaft(1) after removing brushes(2) from the shaft, a second process of cutting to make surface smooth after filling indents caused by friction between bearings(21) and the shaft at both ends of the shaft with welding, a third process of making a new key groove and a new tap by cutting the outer surface after filling the damaged key groove and tap by welding, and a fourth process of straightening bent of the shaft by pressing the bent with a jig and a hydraulic press.

본 발명은 세정용 브러쉬샤프트(Brush Shaft)의 재생방법에 관한 것으로서, 이를 보다 구체적으로 설명하자면 장기간 사용으로 인하여 휘거나 마모된 브러쉬 샤프트를 재생하여 재활용이 가능토록 한 것이다. The present invention relates to a method for regenerating a brush shaft for cleaning, and more specifically, to recycle it by regenerating a curved or worn brush shaft due to long-term use.

일반적으로 세정용 브러쉬샤프트는 샤프트(1) 외주로 브러쉬(2)를 마련한 다음 그 양단을 설치베어링(21)에 각각 설치구성시켜 구동장치(22)로 회전작동케 하는 것으로, 통상 FPD(평판 디스플레이 : Flat Panel Display) 제조공정의 다수 공정에 마련되어 구동장치에 의해 회전하면서 그 외주에 구성된 브러쉬(2)로 FPD의 표면을 세정하여 주는 역할을 한다. In general, the brush brush for cleaning is to provide a brush (2) to the outer periphery of the shaft (1), and then install both ends thereof in the mounting bearing 21 to rotate the drive device 22, usually FPD (flat display : Flat Panel Display) It is provided in many processes of manufacturing process and plays a role of cleaning the surface of FPD with brush (2) formed on the outer circumference while rotating by driving device.

따라서, 상기와 같이 사용되는 브러쉬샤프트는 통상 장기간 사용시 상기 샤프트로 일정한 마모나 휨 등의 문제가 발생하게 되는데, Therefore, the brush shaft used as described above usually causes problems such as constant wear and warp of the shaft when used for a long time.

이는 상기 브러쉬샤프트를 구동장치(22)로 장기간 회전사용할 경우 회전에 의한 샤프트(1)의 휨 발생 또는 샤프트(1) 양단 즉, 설치베어링이 결합되는 결합부위(11)와 키홈(12)과 탭(13)이 형성된 부위가 마찰에 의한 마모 및 파손 등의 문제가 발생하게 되는 것이다 This is because when the brush shaft is rotated for a long time as the driving device 22, bending occurs of the shaft 1 due to rotation or both ends of the shaft 1, that is, the coupling part 11, the key groove 12, and the tab to which the installation bearing is coupled. (13) is a site where the wear and breakage caused by friction occurs

이상과 같이 샤프트가 장기간 사용에 의해 훼손될 경우 종래에는 그 대안으로 상기 훼손된 샤프트를 새로이 구입,사용하는 방법밖에 없었다 As described above, when the shaft is damaged by long-term use, there is only a method of newly purchasing and using the damaged shaft as an alternative.

그러므로 샤프트의 구입에 따른 비용적 부담이 매우 컸음은 물론 조금의 훼손에도 샤프트를 전체 교체하여야 하는 문제를 가지고 있었다. Therefore, the cost burden of the purchase of the shaft was very large and there was a problem that the entire shaft should be replaced even with a slight damage.

본 발명은 상기와 같은 종래의 문제점을 일소하기 위하여 발명된 것으로서, 특히 장기간 사용으로 인해 샤프트에 휨이나 마모 및 파손 등의 문제가 발생시, 상기 샤프트를 다수 재생공정을 통해 재사용이 가능케 하여 재구입에 따른 비용적 낭비를 최소화시켜 주도록 하였다 The present invention has been invented to eliminate the conventional problems as described above, especially when problems such as bending, abrasion, and damage occurs in the shaft due to long-term use, it is possible to reuse the shaft through a plurality of regeneration process to repurchase Minimized cost waste

이하 첨부된 도면에 의거 본 발명을 더욱더 상세히 설명하자면 도 1은 브러쉬샤트프의 사용상태를 나타낸 도면으로서, 샤프트 외주로 브러쉬가 설치됨과 동시에 브러쉬 양측단이 각각 설치베어링에 설치되어, 구동장치에 의해 회전구동하게 된다. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a view illustrating a state of use of a brush shaft, and at the same time a brush is installed at the outer periphery of the shaft, and both ends of the brush are respectively installed in an installation bearing. It will rotate.

그리고 도 2는 상기와 같은 작용으로 장기간 사용시 샤프트에 휨,마모 및 파손 등의 문제가 발생하게 되는데, 이를 나타낸 도면이다. In addition, Figure 2 is a problem such as bending, wear and breakage occurs in the shaft during long-term use by the same action as above, it is a view showing this.

따라서, 상기와 같은 브러쉬샤프트를 FPD(평판 디스플레이 : Flat Panel Display) 제조공정에서 FPD의 세정목적으로 장기간 사용 때에, Therefore, when the brush shaft as described above is used for a long time for the purpose of cleaning the FPD in the FPD (Flat Panel Display) manufacturing process,

샤프트(1)로 회전에 의한 휨 현상이나, 샤프트(1) 양단부 즉, 설치베어링이 결합되는 샤프트의 결합부위(11)로 설치베어링(21)과의 장기간 마찰에 의한 마모로 부분 함몰현상, 그리고 샤프트(1)에 형성된 키홈(12)과 탭(13) 부위가 마모 내지는 파손 등이 발생하게 되면, Partial depression due to warpage due to rotation to the shaft 1 or abrasion due to prolonged friction with the mounting bearing 21 at the coupling portion 11 of the shaft 1, that is, the shaft to which the mounting bearing is coupled, and When the key groove 12 and the tab 13 formed on the shaft 1 wear or breakage occurs,

본 발명에서는 상기 훼손된 샤프트(1)를 다수의 재생공정을 통해 재생시키되, In the present invention, the damaged shaft 1 is regenerated through a plurality of regeneration processes,

상기 샤프트(1)를 회수하여 그 외주에 설치된 브러쉬(2)를 제거한 다음 샤프트(1)의 훼손 상태를 점검하는 제 1공정과;A first step of recovering the shaft (1), removing the brush (2) installed on the outer circumference thereof, and then checking the damaged state of the shaft (1);

상기 제 1공정을 통해 샤프트(1)의 휨발생, 마모 및 파손 등의 훼손상태가 확인되면, 먼저 샤프트(1)의 양단부 즉 설치베어링(21)과 결합되는 샤프트의 결합부위(11)에 발생된 마모에 의한 함몰부위를 용접으로 충진시켜 메꾼 다음 그 외주표면을 절삭하여 평탄작업을 실시하는 제 2공정과;When a damaged state such as bending, abrasion, and damage of the shaft 1 is confirmed through the first process, first, the shaft 1 is generated at the coupling portion 11 of the shaft coupled to both ends of the shaft 1, that is, the installation bearing 21. A second step of filling and filling the recessed portion caused by wear by welding and then cutting the outer peripheral surface to perform a flattening operation;

상기 샤프트(1) 양단에 형성된 키홈(12)과 탭(13)에 발생된 마모 내지는 파손부위를 용접으로 충진시켜 완전히 메꾼 다음 그 외주표면을 절삭하여 평탄 작업 후 다시 키홈(12)과 탭(13)을 형성하는 제 3공정과;Abrasion or damage generated in the key grooves 12 and the tabs 13 formed at both ends of the shaft 1 are completely filled by welding, and then completely filled, and then the outer peripheral surface is cut, and the key grooves 12 and the tabs 13 are again flattened. Forming a third process;

상기 샤프트(1)를 통상 유압에 의해 작동하는 유압프레스로 그 수평상태를 확인하면서 휘어진 부위를 유압프레스의 치구로 가압하여 일직선상의 수평이 이루어질 수 있도록 하여 주는 제 4공정을 순차적으로 실시하여 훼손된 샤프트를 다시 재사용가능케 하여 준다. Damaged shaft by sequentially performing a fourth process of pressing the curved part with the jig of the hydraulic press while checking the horizontal state of the shaft 1 by a hydraulic press normally operated by hydraulic pressure. Make it reusable again.

여기서 본 발명에서 제시하는 다수 공정을 필요에 따라 그 순서를 달리할 수도 있고 또 브러쉬샤프트의 장기간 사용으로 인해 발생하는 위 문제점 중, 일부 문제점 발생시 그 문제점을 해결하여 주는 해당 공정만 별도 실시하여 샤프트를 재사용할 수도 있다. Here, a plurality of processes presented in the present invention may be changed in order as necessary, and among the above problems caused by long-term use of the brush shaft, only a corresponding process that solves the problem when some problems occur is performed separately. It can also be reused.

이상과 같이 본 발명은 브러쉬샤프트의 훼손시 샤프트를 재생하여 재활용이 가능케 하여 주므로 종래에 샤프트구입에 따른 비용적 부담을 현저히 절감케 하여 주는 이점을 제공하게 된다 .As described above, the present invention enables regeneration by recycling the shaft when the brush shaft is damaged, thereby providing an advantage of remarkably reducing the cost burden according to the conventional shaft purchase.
