Problems solved by technology

[0002] At present, electronic products such as mobile phones and tablet computers are paying more and more attention to appearance, and they all need to have higher flatness and surface finish. Therefore, it is usually necessary to test the flatness and finish of the shell. The existing detection methods are generally The inspectors conduct manual operations and judge the flatness and smoothness of the inspected object with the naked eye. This method is inefficient and inaccurate, and is prone to misjudgment. Common shell inspections are surface oil, scratches, air bubbles or Dust etc.
