Abstract
Disclosed is a PC board printing machine with cantilever-supported printing head and stencil holders and bi-directionalty movable printing table, and more particularly to a PC board printing machine which includes a cantilever mechanism, a motor dual-rail transmission mechanism, a exchangeable printing head and stencil cleaning lift-up mechanism, a simple stencil frame holder and dual-oil-cylinder stencil lifting mechanism, and an automatically bi-directionally movable printing table mechanism to produce high printing quality.
Claims6
A PC board printing machine with a cantilever-supported printing head holder and stencil holder and a bi-directionally movable printing table, comprising;
- a movable cantilever support mechanism for vertically moving the printing head holder and the printing stencil holder;
- a motor operated dual-rail transmission mechanism fixed to said cantilever mechanism for moving said printing head holder laterally and reciprocatingly;
- an exchangeable printing head and stencil cleaning lift-up mechanism connected to said printing head holder and having printing scrapers adjustable in shape and position to enable printing in different manners;
- a stencil frame holder and dual-oil-cylinder stencil lifting mechanism having two cantilever arms attached to a lower portion of said cantilever support mechanism and said motor operated dual-rail transmission mechanism for adjustably holding a printing stencil between said two cantilever arms;
- and a bi-directionally movable printing table mechanism disposed on a top platform below said printing head holder and said two cantilever arms to support an object to be printed and to move laterally and longitudinally relative to said top platform.
