Multi-view vision inspection system and method for ink-jet printing

Abstract

The invention belongs to the technical field related to ink-jet printing visual inspection, and discloses a multi-view visual inspection system and method for ink-jet printing, and the method mainly comprises the following steps: (1) firstly, detecting and determining the installation angle of a nozzle; then, performing trial printing to detect and determine the volume, speed and angle of flying ink drops; and finally, detecting and determining the deflection angle of the spray orifice array, the position and angle of the substrate and the offset distance of ink dripping points; and (2) carrying out ink-jet printing according to the obtained parameters, and carrying out liquid film detection on the printed substrate by adopting a predefined defect type after the substrate is printed. Various control parameters required by the whole ink-jet printing process can be detected, the defect that only a single module can be detected in an existing ink-jet printing detection method can be effectively overcome, and higher-precision and higher-efficiency detection of the whole ink-jet printing process is achieved.

Description

technical field [0001] The invention belongs to the related technical field of inkjet printing visual detection, and more specifically relates to a multi-eye visual detection system and method for inkjet printing. Background technique [0002] Inkjet printing technology is used in the manufacture of display screens, flexible sensors and other fields. Compared with traditional printing technology, inkjet printing technology is non-contact printing, and the alignment accuracy can reach sub-micron level, so it is a high-efficiency, A low-cost, green-friendly electronic manufacturing technology with the advantages of simple process, high printing resolution, and less material waste. In the process of inkjet printing, due to the small volume of ink droplets and the area of ​​pixel pits, the detection accuracy of the overall visual inspection system is extremely high. Using inkjet printing technology to print on demand, jetting ink droplets to form patterned devices or uniform Th...
