Description

자동차 부품제조장치의 워크위치 결정방법How to Determine Work Position of Automobile Parts Manufacturing Equipment

본 발명은 자동차 부품제조장치의 워크위치를 결정하는 방법에 관한 것으로, 특히 워크위치를 결정하는데 있어서 워크의 특정한 형상을 이용하여 보편적으로 이용되는 위치감지센서의 센싱을 재확인함으로써 워크의 위치결정이 정확하게 이루어지도록 된 자동차 부품제조장치의 워크위치 결정방법에 관한 것이다.The present invention relates to a method for determining the work position of an automobile parts manufacturing apparatus, and in particular, in determining the work position, the positioning of the work can be accurately determined by reconfirming the sensing of a universally used position sensor using a specific shape of the work. It relates to a method for determining the work position of the automobile parts manufacturing apparatus to be made.

주지된 바와 같이, 자동차 부품제조장치는 모터의 회전력을 이용하여 워크를 가공하는 장치가 가장 일반적인 바, 이러한 자동차 부품제조장치에 있어서 워크의 정확한 위치결정은 제품의 성능 및 수명에 중요한 요인으로 작용된다.As is well known, an automobile parts manufacturing apparatus is a device that processes the workpiece by using the rotational force of the motor is the most common bar, the precise positioning of the workpiece in such automotive parts manufacturing apparatus is an important factor in the performance and life of the product. .

종래에는 자동차 부품제조장치의 위치를 결정하는 방법으로 위치감지센서를 이용하는 것이 널리 이용되고 있는데, 이를 개략적으로 설명하면, 우선 자동차 부품제조장치에 워크가 얹혀져서 워크구동모터가 회전하면 위치감지센서에서 워크의 정위치를 감지하고, 워크의 정위치가 감지되면 워크회전모터가 정지하여 정위치에 고정되어 가공이 이루어지게 된다.Conventionally, the position sensor is widely used as a method of determining the position of a vehicle parts manufacturing apparatus. To explain this, first, a work is placed on an automobile parts manufacturing apparatus so that the work drive motor rotates, When the exact position of the workpiece is sensed and the correct position of the workpiece is detected, the workpiece rotation motor is stopped and fixed at the fixed position, thereby processing is performed.

그러나, 상기 위치감지센서를 이용하여 워크의 위치를 감지하는 경우, 워크회전모터의 정지시에 슬립 등의 현상이 발생하여 센싱이 부정확하게 이루어지는 경우가 빈번하게 발생되어지는데, 종래에는 이를 방지하는 방안이 마련되지 못하여워크의 위치결정이 제대로 이루어지지 못한 상태에서 가공됨으로써 제품의 성능 및 수명이 감소되는 문제가 발생되었다.However, when the position of the workpiece is sensed by using the position detection sensor, a phenomenon such as slip occurs when the work rotation motor stops, so that the sensing is frequently inaccurate. This problem is caused by a problem that the performance and life of the product is reduced by processing in a state in which the positioning of the workpiece is not properly made.

또한, 상기와 같이 위치결정이 제대로 되지 못한 상태에서 가공이 이루어지면, 가공툴(Tool)의 파손되어 그 수명도 감소되는 문제가 있었다.In addition, when machining is performed in a state in which the positioning is not properly performed as described above, there is a problem that the machining tool (Tool) is broken and its life is also reduced.

이에 본 발명은, 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로, 워크위치를 결정하는데 있어서 워크의 특정한 형상을 이용하여 보편적으로 이용되는 위치감지센서의 센싱을 재확인함으로써 워크의 위치결정이 정확하게 이루어지도록 하는 자동차 부품제조장치의 워크위치 결정방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, and the positioning of the work is made accurately by re-checking the sensing of the universally used position sensor using the specific shape of the work in determining the work position. It is an object of the present invention to provide a method for determining a work position of an automobile parts manufacturing apparatus.

이상 설명한 바와 같이, 본 발명에 의하면, 워크위치를 결정하는데 있어서 워크의 특정한 형상을 이용하여 보편적으로 이용되는 위치감지센서의 센싱을 재확인함으로써 워크의 위치결정이 정확하게 이루어져 위치결정오류에 의한 제품불량발생이 방지되는 효과가 있다.As described above, according to the present invention, in determining the workpiece position, the workpiece position is accurately determined by reconfirming the sensing of a universally used position sensor by using a specific shape of the workpiece. This has the effect of being prevented.

또한, 상기 위치결정오류시에는 가공톨(Tool)에 무리가 발생하여 그 수명이 단축되는 문제가 있었는데, 위치결정이 정확하게 이루어짐으로써 부품제조장치의 제품수명이 연장되는 효과도 기대된다.In addition, when the positioning error occurs, there is a problem that the life of the tool is shortened and the life thereof is shortened. However, since the positioning is performed correctly, the product life of the component manufacturing apparatus is also expected to be extended.
