Screen printing apparatus

摘要

A screen printing apparatus includes print executing parts, first and second substrate loading parts and a substrate unloading part, and first and second substrate support tables for supporting a substrate. The first substrate support table moves between a first receiving position where the substrate loaded from the first substrate loading part is received, and a sending position where the substrate is unloaded from the substrate unloading part. The second substrate support table moves between a second receiving position where the substrate loaded from the second substrate loading part is received, and the sending position. The print executing parts are respectively placed at positions on the substrate support tables where printing on the substrate is enabled.

1. A screen printing apparatus comprising:
a print executing part positioned between a substrate loading position which enables loading of a substrate, and a substrate unloading position which enables unloading of a printed substrate, both of which are juxtaposed in a certain direction, the print executing part being configured to perform screen printing on the substrate; a substrate support table receiving a substrate loaded from the substrate loading position, supporting the substrate so that the print executing part enables printing on the substrate, and unloading the printed substrate from the substrate unloading position; and a control unit controlling the substrate support table, the substrate support table including a first substrate support device and a second substrate support device which are respectively movably juxtaposed movably in a Y axis direction which is orthogonal to an X axis direction defined as the certain direction, the first substrate support device and the second substrate support device having a common area in which movable areas of the first and the second substrate support devices partially overlap, the control unit executing one of operational controls including: a first operational control in which the first substrate support device and the second substrate support device receive a substrate from a first substrate loading position and a second substrate loading position which are respectively predetermined as the substrate loading position at positions which are mutually different in the Y axis direction and which are outside of the common area and the first substrate support device and the second substrate support device unload a print-processed substrate from the substrate unloading position positioned within the common area; a second operational control in which the first substrate support device and the second substrate support device receive a substrate from the substrate loading position positioned within the common area and the first substrate support device and the second substrate support device unload a print-processed substrate from a first substrate unloading position and a second substrate unloading position which are respectively predetermined as the substrate unloading position at positions which are mutually different in the Y axis direction and which are outside of the common area; and a third operational control in which the first substrate support device and the second substrate support device receive a substrate from a first substrate loading position and a second substrate loading position which are respectively predetermined as the substrate loading position at positions which are mutually different in the Y axis direction and which are positioned within the common area and the first substrate support device and the second substrate support device unload a print-processed substrate from a first substrate unloading position and a second substrate unloading position which are respectively predetermined as the substrate unloading position at positions which are mutually different in the Y axis direction and which are positioned within the common area, and the print executing part being placed at a position at which the print executing part enables screen printing on the substrate supported by each of the substrate support devices.
