Circuit board air-bearing vibrating drilling machine and operating method thereof

Abstract

A circuit board air-bearing shaft vibration drilling machine includes an air-bearing assembly, a floating shaft, and a magnetic induction assembly. The air-bearing assembly has a movable space, a first air bearing, and a second air bearing. The movable space has a first distance in a first direction and a second distance in a second direction. The floating shaft is movably disposed within the movable space and has a first bearing portion and a second bearing portion. The first bearing portion has a bearing width in the first direction, and the second bearing portion has a bearing thickness in the second direction. The bearing width is smaller than the first distance, and the bearing thickness is smaller than the second distance, allowing the floating shaft to float within the movable space via the air bearings. Furthermore, by changing the magnetic poles between the floating shaft and the magnetic induction assembly, the floating shaft can be driven to reciprocate up and down to generate vibration during drilling.
