第一章系统描述

1.2.3

光学系统（

Fiduciallymark

光学对准标记）

Optical system(Fiduciallymark optical

alignment mark)

标记点探测

Fiducial Mark Detection

用一个 CCD 相机通过网板和基板上两个标志点进行识别

Use a CCD camera to detect through the two fiducial marks

on the stencil and base board

调整方式

Alignment Mode

用相机探测到 PCB 和网板位置，通过视觉校正系统软件控制

万向工作台作 X—Y—θ方向修正，实现网板与基板的对准

Use camera to detect the position of PCB and stencil.

Correct the X—Y—θdirection of the worktable through the

visual alignment system software and insure the alignment

of the stencil and base board.
