Abstract
An inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. A pair of substrate supporting tables juxtaposed in a specific direction is provided. Screen printing is alternately performed by a single print executing section in a common area which can be shared by the two substrate supporting tables. In doing so, when one substrate supporting table located at a print position among the pair of substrate supporting tables starts exiting the print position, the other substrate supporting table starts entry to the print position.
Claims20
A screen printing machine comprising:
- a pair of substrate supporting tables including one substrate supporting table and a counterpart substrate supporting table, each of the pair of substrate supporting tables being provided for holding a substrate that is a print object, the substrate supporting tables being juxtaposed along a specific direction, the specific direction being horizontally perpendicular to a conveying direction of the substrate;
- a printing executing section that performs a printing process on the substrate held by each of the substrate supporting tables, the printing process being performed at a print position set in a common area being located between the pair of substrate supporting tables with respect to the specific direction along which both of the substrate supporting tables are movable;
- a substrate supporting table driving mechanism configured to individually drive the pair of substrate supporting tables in the specific direction;
- and
- a control unit configured to control the substrate supporting table driving mechanism so that the one substrate supporting table that moves into a printing process enters the print position by moving in a direction approaching the counterpart substrate supporting table along the specific direction during movement of the counterpart substrate supporting table that has completed the printing process at the print position as the counterpart substrate supporting table is exiting the print position by moving in a direction receding along the specific direction,
- wherein
- the control unit controls the substrate supporting table driving mechanism so that the one substrate supporting table completes entry to the print position after the counterpart substrate supporting table completes exiting from the print position, in a way that at least parts of an exit period for the one counterpart substrate supporting table exiting the print position and an entry period for the one substrate supporting table entering the print position overlap each other.
