A plurality of trimmers for setting the vacuum level of the vacuum sensor, a plurality of comparators for comparing the analog output signal of the vacuum sensor and the output signal of the trimmer, and a plurality of lamps respectively connected to the outputs of the comparator and indicating the state of reaching the vacuum level, And the output of the comparator is connected to the main controller through an interface, and sets a plurality of vacuum levels by using a plurality of trimmers in the apparatus, and trims the level signal detected by the vacuum sensor and the set vacuum level. Compare the output signal through a plurality of comparators, and when the output signal of the comparator is logic "high" To the lighting of a plurality of display lamps connected to the output of the comparator in this order to be detected, it characterized in that the type or the state of suction of the part.

상술한 본 발명에 의하면, 부품의 크기, 모양 등을 기준으로 사용자가 복수의 흡착 진공레벨로 부품을 분류한다음, 헤드에 부품을 흡착시, 흡착되어진 부품의 진공상태가 미리 설정된 흡착 진공 레벨에 도달하지 못하는 경우에는 비정상 흡착으로 판단하여 장착시키기 전에 흡착실패를 발생시켜, 기판에서의 장착실패를 감소시킬수 있으므로 부품의 흡착의 실패를 감소하며 공정시간을 단축하고, 부품을 장착하는 제품의 신뢰성을 향상시킬 수 있으며, 흡장착으 실패없이 하나의 칩 마운터를 이용하여 여러가지 종류의 부품을 기판에 실장할 수 있는 효과를 갖는다.According to the present invention described above, the user classifies the parts into a plurality of adsorption vacuum levels based on the size, shape, etc. of the parts, and when the parts are adsorbed on the head, the vacuum state of the adsorbed parts reaches a predetermined adsorption vacuum level. If it fails to do so, adsorption failure may occur before mounting by determining that it is abnormal adsorption, thereby reducing the mounting failure on the board, thus reducing the failure of adsorption of components, shortening the process time, and improving the reliability of the product to which the components are mounted. It is possible to mount various components on a board using a single chip mounter without failing in mounting and mounting.
