Abstract

A vibration apparatus in an automatic pill dispensing machine includes a pill box and a vibration unit connected to the pill box. The vibration unit includes a motor, a vibration member and a first cam. The vibration member is connected to the first cam and the pill box. The motor is powered on to rotate the first cam. The first cam resists against the vibration member. The first cam moves the vibration member and the pill box between a first height and a second height. The vibration member vibrates the pill box to separate pills from each other in the pill box when the first cam moves the pill box between the first height and the second height.
