Research On The On-Line Detection System Of Shell Defects Of Crystal Oscillator Based On Machine Vision

Machine vision technique is used to machining, packaging, electron and other fields characterized by high speed and high accuracy. In this thesis, the on-line detection system is designed based on machine vision. System relates to optics, mechanics, electronics and image processing. It can detect the defective shell of crystal oscillator with other auxiliary equipments. Thesis mainly aims at research on following aspects:1,An apparatus for shell of crystal oscillator detection is designed. The apparatus include three parts, First, acquisition equipment selection (industry camera, image acquisition card and so on); Second, illumination apparatus is designed; Third, fixation machine is designed.2, Control apparatus is designed. Function of control system includes controlling movement, communicating with Host and send outer...
