Automatic replacement of mask by replacement of printed circuit board of screen printer

摘要

The present invention relates to an automatic mask replacement apparatus for replacing a printed circuit board of a screen printer, and is capable of automatically replacing a mask installed in a screen printer with a new mask, thereby avoiding unnecessary time, labor, It is possible to switch to production of printed circuit board quickly, and it is advantageous to increase productivity by improving productivity and shortening working time. Also, By minimizing the change rate of the condition, it is possible to minimize the occurrence of product failure due to the replacement work, minimize the movement distance due to the mask replacement, minimize the time for replacing the mask, It is possible to shorten the time corresponding to the size and to use it universally. The present invention relates to a mask automatic replacement apparatus for replacing a printed circuit board of a screen printer capable of reducing restrictions on the thickness of a printed circuit board due to minimization of a height restriction between a mask and a backup jig through transfer of a backup jig.
