Abstract

The invention belongs to the related field of ink-jet printing visual inspection, and discloses a fused ink detection device suitable for large-area substrate printing. The device comprises a substrate conveying module, a camera motion module and a jet printing detection module. The substrate conveying module comprises a substrate bearing device, an X-direction motion mechanism and a position feedback device. The camera motion module comprises a rack, a Y-direction motion mechanism and a Z-direction motion mechanism. The jet printing detection module comprises multiple sets of cameras, lensesand light sources. The cameras move relative to the direction X and the direction Y between substrates for image collection and image splicing. The invention further discloses a corresponding method used for acquiring fused ink images and detecting defects, uniformity and other performance. Meanwhile, a printing effect can be evaluated according to the detection result. By means of the fused ink detection device and method, ink-jet printing and fused ink detection can be achieved on the same device, and high-efficiency and high-accuracy defect and uniformity detection can be carried out on fused ink on the large-area substrates.

Description

technical field [0001] The invention belongs to the related field of inkjet printing visual detection, and more specifically relates to a fusion ink detection device and method suitable for large-area substrate printing. Background technique [0002] Inkjet printing technology is being widely used in the manufacture of display screens, flexible sensors and other fields. Compared with traditional evaporation technology, it has the advantages of simple process, high printing resolution and less material waste. In the process of inkjet printing, the positioning accuracy and the stability of the spraying process will affect the fusion state of the ink on the substrate. For example, in the TFE film packaging process, it is necessary to detect the uniformity of the ink thickness. For defects such as liquid position, ink volume, and scattered spots, the integrated ink detection can directly reflect the printing effect, which is conducive to improving the yield rate of printed produ...
