Description

센서 마그네트를 부착한 슬립링{Slip ring with sensor magnet}Slip ring with sensor magnet {Slip ring with sensor magnet}

본 발명은 센서용 마그네트를 부착한 슬립링에 관한 것으로, 특히 감시카메라에 장착되는 슬립링의 구조 및 그 제조방법에 관한 것이다.The present invention relates to a slip ring with a magnet for a sensor, and more particularly, to a structure of a slip ring mounted on a surveillance camera and a method of manufacturing the slip ring.

일반적으로 감시카메라 시스템에는 카메라모듈이 구비되며, 카메라모듈은 하우징과 상기 하우징에 장착된 팬 및 틸트(Tilt) 메카니즘(Mechanism)을 포함한다.In general, a surveillance camera system is provided with a camera module, the camera module includes a housing and a pan and tilt mechanism mounted on the housing.

팬 및 틸트 메카니즘은 카메라를 좌우로 움직이는 팬 모터와 카메라를 상하로 움직이는 틸트 모터를 포함한다.The pan and tilt mechanisms include a pan motor that moves the camera left and right and a tilt motor that moves the camera up and down.

팬 모터는 하우징에 대하여 안정하도록 팬 및 틸트 메카니즘에 장착되고, 팬 및 틸트 메카니즘을 위해 내부에 슬립링이 장착되고, 상기 슬립링은 모터 및 카메라에 전기적접속을 제공하면서 작동 중에도 배선의 꼬임이 없도록 하는 기능을 담당하게 된다.The fan motor is mounted on the pan and tilt mechanism to be stable with respect to the housing, and there is a slip ring inside for the pan and tilt mechanism, which provides an electrical connection to the motor and the camera so that the wires are not twisted during operation. Will be in charge of

또한 카메라의 영점조절 및 위치제어를 위해 모터제작자들이나 사용자들은 광학적 엔코더(Encoder)를 이용한 센싱방법을 주로 사용해 오고 있지만, 이 경우 좌표에 대한 오류 등에 의한 품질의 한계가 있으며 가격 또한 비싸다.In addition, motor makers and users have mainly used sensing methods using optical encoders to control the camera's zero point and position, but in this case, there is a limitation of quality due to coordinate error and the price is expensive.

상술한 마그네트를 모터 어셈블리와 결합하는 일반적인 제조방법으로는 부가적인 부품들의 조작 및 제조공정의 추가사항이 발생하게 되며 따라서 센싱기능을 가지는 모터의 제조비용이 증가하게 된다는 문제가 있었다.As a general manufacturing method for combining the above-described magnet with the motor assembly, there are problems in that additional parts are manipulated and additionally manufactured, thereby increasing the manufacturing cost of the motor having the sensing function.

또한 상기 모터의 제조비용이 증가하는 것뿐만 아니라, 마그네트를 모터 어셈블리에 결합시키는 기존방법은 일반적으로 마그네트를 로터 축에 접착제를 통해 접착하거나 로터 축에 있는 마디(knurl)를 누르기 때문에 마그네트가 모터하우징에 계속 유지하기에 비효율적이고, 이에 의해 센싱의 불량을 야기시킨다는 문제가 있었다.In addition to an increase in the manufacturing cost of the motor, the existing method of joining the magnet to the motor assembly generally adheres the magnet to the rotor shaft with an adhesive or presses a knurl on the rotor shaft, so that the magnet has a motor housing. There is a problem that it is inefficient to keep on, thereby causing a poor sensing.

또한 모터의 축이 높은 RPM으로 회전하게 되면 접착본드가 종종 마그네트를 축에 고정시키기에 모자라게 되거나 혹은 모터가 작동할 때 마디(knurl)로부터 떨어져 마그네트는 센서에 플럭스라인(Flux Line)을 재공급할 수 없게 되고 정보수집 등을 할 수 없게 된다는 문제가 있었다.Also, if the motor's shaft rotates at high RPM, the adhesive bonds often fail to secure the magnet to the shaft, or the magnet can feed the flux line back to the sensor away from the knurl when the motor is running. There was a problem that it was impossible to collect information, and so on.

본 발명의 목적은 상술한 바와 같은 문제점을 해결하기 위해 이루어진 것으로서, 감시카메라의 센싱을 위해 슬립링의 내부에 센서용 마그네트를 장착시킨 센서용 마그네트를 부착한 슬립링을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to solve the problems as described above, and to provide a slip ring having a magnet for a sensor equipped with a sensor magnet inside the slip ring for sensing the surveillance camera.

본 발명에 따른 센서용 마그네트를 부착한 슬립링에 의하면, 종래의 감시카메라에 사용되어진 센싱방법인 광학적 엔코더를 이용한 방법은 가격이 비싸며 품질에 한계가 있었고, EMF에 기반을 둔 방법 또한 정확도에서 미흡하여, 종래의 센싱방법과 달리 센서용 마그네트를 슬립링 결합체의 봉축의 홈부에 끼움으로서 모터의 제조비용 및 공정을 줄이고, 모터의 회전에 따른 센싱불량을 막을 수 있다는 효과가 얻어진다.According to the slip ring equipped with a sensor magnet according to the present invention, the method using an optical encoder, which is a sensing method used in a conventional surveillance camera, is expensive and limited in quality, and the EMF-based method also lacks in accuracy.
