Abstract

흡착기에 부품이 흡착된 유무를 판별하는 부품 흡착 판단방법에 관한 내용이 개시되어 있다. 흡착노즐이 부품을 흡착하기 전에 진공패드에 놓인 상태 및 허공에 놓인 상태의 진공압을 측정한 제1진공압 및 제2진공압을 측정하고, 흡착노즐이 부품을 흡착했을 경우의 참고 제1퍼센트레벨값 및 상기 부품을 흡착하지 않았을 경우의 참고 제2퍼센트 레벨값을 입력하고, 제1진공압과 제2진고압의 차이값에 대한 임의의 참고 제3진공값을 입력하고, 상기 측정된 값과 입력된 값을 이용하여 부품이 흡착노즐에 흡착된 상태를 판단한다. 따라서 헤드, 흡착노즐 및 부품에 따라 변화하는 진공값을 절대값이 아닌 진공패드를 이용하여 측정한 진공합 및 허공 상태에서 측정한 진공압에 대한 상대값을 퍼센트로 계산하기 때문에 절대값이 변해도 부품의 흡착 상대를 신뢰서 있게 반별할 수 있다.Discloses a component adsorption determination method for determining whether or not a component is adsorbed on an adsorption machine. The first vacuum pressure and the second vacuum pressure in which the suction nozzle is placed on the vacuum pad before the component is adsorbed and the vacuum pressure measured in the state of being placed in the air are measured, and when the suction nozzle has adsorbed the component, Level value and a reference second percentage level value when the component is not adsorbed, inputting any reference third vacuum value for the difference between the first vacuum pressure and the second vacuum pressure, And a state in which the component is adsorbed to the adsorption nozzle by using the input value. Therefore, since the relative value of the vacuum value, which varies depending on the head, the suction nozzle and the component, with respect to the vacuum pressure measured in the vacuum pad and the vacuum pressure measured in the vacuum pad instead of the absolute value is calculated as a percentage, The adsorption partner of the adsorbent can be reliably discarded.
