Title: 펌프 제어 시스템 및 측정 변수 제어 방법
IPC: G05D16/20
Filed: 1999-03-25
Abstract: 본 발명은 처리 유니트에서 복합 펌프 작동에 적용할 수 있는 제어 시스템에 관한 것이다.  압력과 같은 측정 변수는 마스터 제어기에 의해 검출된다.  상기 마스터 제어기는 신호를 각 펌프의 구동기에 전송하거나, 또는 2개의 펌프 출력을 다른 방식으로 제어한다.  상기 마스터 실린더는 측정 변수에서의 변화에 응답하여 2개의 펌프에 상이한 신호를 동시에 전송한다.  그 결과, 한쪽 펌프에서의 응답 시간이 다른쪽 펌프 보다 빠르게 된다.  따라서, 측정 변수의 양호한 설정값으로부터의 미세한 이탈은 주로 빠르게 응답하도록 설정된 펌프에 의해 처리된다.  측정 변수의 양호한 설정값으로부터의 심각한 이탈을 초래하는 급격한 업셋은 한쪽 펌프를 빨리 응답시키고 그 용량을 급격히 변화시켜 측정 변수를 필요한 설정값으로 복귀시키며, 그 동안 다른쪽 펌프는 이보다 느리게 응답하므로써 항상 양호한 전방 유체 유동비를 유지하여 처리 유니트가 중단되는 것을 방지한다.  신속응답형 펌프의 손실이 검출됨에 따라, 마스터 제어기는 느리게 응답하는 펌프의 응답 시간을 자동으로 상승시키므로써, 그 용량은 측정 변수를 목표 상태로 유지시킬 수 있을 정도록 매우 신속하게 변화될 수 있다.  펌프 상에서 상이한 응답 시간을 사용하게 되므로써, 예를 들어 증기 터빈에 의한 작동시 펌프 상호간의 경쟁이 제거된다.  또한, 이러한 제어 시스템이 구비된 펌프는 처리 유니트의 중단을 유발시킬 수도 있는 양 펌프의 정지 상태를 초래하지 않고서도 대형 처리 업셋에 신속히 응답할 수 있다.

Abstract: PURPOSE: A sensing device of operation of a robot chuck for transporting wafer is provided to monitor the correct state of the motion of the robot chuck, picking up and transporting wafer to prevent the malfunction. CONSTITUTION: A cam block(32) is installed on the moving axis(30). Two rollers(40,42) are mounted on chuck axes(36,38) located on both sides of a T-type sensor dog(34). Two pairs of sensors(44,44',46,46') operate to sense the either side motion of the sensor dog along its moving direction. The robot chuck is attached to the bottom part of the chuck axis. Each end of rollers is connected to a spring(48) so that it can stretch and contract according to the motion of the cam block.
