Title:
CURVED SURFACE SCREEN PRINTING DEVICE AND CURVED SURFACE SCREEN PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/162469
Kind Code:
A1
Abstract:
This curved surface screen printing device (1) is provided with a pedestal (2), a screen plate (3), a squeegee (4), and a printing control unit configured so as to perform printing on a base material (G) by having the pedestal (2) rotate about a rotating shaft (24) and having the pedestal (2), the screen plate (3), and the squeegee (4) move in a relative manner with respect to an orthogonal direction of the rotating shaft (24). The printing control unit is provided with a rotational angle control unit (63) configured so as to apply a force for causing the pedestal (2) to rotate to one side of the orthogonal direction that is horizontal to the rotating shaft (24) of the pedestal (2), and a load control unit (64) configured so as to apply a force for causing the pedestal (2) to rotate to the other side of the orthogonal direction that is horizontal to the rotating shaft (24). The rotational angle control unit (63) is provided with a rotational force application mechanism where a backlash is present between intermeshed constituent elements. The load control unit (64) is configured so as to have loaded, about the rotating shaft (24), a moment that is greater than the moment about the rotating shaft (24) that is produced by a printing pressure of the squeegee (4).
