An inkjet printing alignment device

Abstract

This invention belongs to the field of inkjet printing technology, specifically an alignment device for inkjet printing. Addressing the problems of existing clamping mechanisms that directly contact the substrate surface, inevitably obscuring the edge areas of the substrate and lacking targeted temperature control design, the following solution is proposed: A printing table is included, with multiple identical alignment mechanisms on the top for aligning and fixing the inkjet-printed substrate. Each alignment mechanism includes an adsorption fixing component, which includes a groove I located below the printer on the top of the printing table. In this invention, negative pressure is generated by the evenly distributed adsorption holes on the top of the fixing table, achieving unobstructed adsorption and fixing from the bottom surface of the substrate. A flow channel is also created inside the fixing table, where a constant-temperature coolant circulates, controlling the contact temperature between the fixing table and the substrate surface. This ensures stable substrate surface temperature and avoids localized ink bleeding or poor adhesion due to temperature fluctuations.
