When the hollow pen body 110 of the vacuum suction pen is connected with a vacuum hose through a pen body tail post 113, the vacuum hose is connected with a vacuum generator, so that vacuum is generated in the air passage of the hollow pen body 110, and further an adsorption port 112 of the adsorption pen head 111 generates suction to adsorb the element; the piezoelectric detection module 120 is the same as the air passage in the hollow pen body 110, the piezoelectric detection module 120 can detect the air pressure in the air passage of the hollow pen body 110, and the feedback module 130 can feed back the air pressure condition in the air passage of the hollow pen body 110 according to the detection result of the piezoelectric detection module 120, so that the operator can perform corresponding processing according to the feedback result. The specific using process is as follows: before the operating personnel used the vacuum suction pen to adsorb the component, earlier detect the atmospheric pressure of hollow pen body 110 through piezoelectricity detection module 120, and whether enough big according to the result that piezoelectricity detection module 120 feedbacks to feedback module 130, when atmospheric pressure was enough big, then open the air flue of vacuum suction pen through vacuum switch 114, adsorb the component through adsorbing mouth 112 on the absorption nib 111, and when atmospheric pressure was not enough, then close the air flue of vacuum suction pen through vacuum switch 114, make the absorption mouth 112 on the absorption nib 111 can't adsorb the component, the function of vacuum suction pen automated inspection atmospheric pressure has been realized, the error that causes has been avoided considering to judge simultaneously, reduce the risk that the component absorption dropped. Wherein, be equipped with the through-hole on the hollow pen body 110, through-hole and air flue intercommunication, vacuum switch 114's one end is passed through the spring setting in the through-hole, and when vacuum switch 114 was pressed, then vacuum switch 114 stopped up the air flue, and when releasing vacuum switch 114, because the effect of spring, vacuum switch 114 was flicked for the air flue is unobstructed.
