Digital embroidered cloth printing method capable of realizing intelligent visual guidance

Abstract

The invention discloses a digital embroidered cloth printing method capable of realizing intelligent visual guidance. According to the digital embroidered cloth printing method, embroidered cloth is a cross-stitch. The digital embroidered cloth printing method comprises the following specific steps: (a) regulating the rotating speed of a belt guiding machine to be matched with a printer, and stopping the belt guiding machine after conveying the to-be-printed embroidered cloth to a digital printing region; (b) carrying out image acquisition by utilizing a long-line-array CIS (contact image sensor) camera; (c) after acquiring an image, transmitting data to a PC to carry out image processing; (d) positioning all grid regions to be subjected to pattern printing on a cross-stitch image; (e) controlling an ink-jet printing head to print a correct pattern on an accurate position according to the texture situations of the embroidered cloth positioned by visual guidance; (f) then returning to the step (a). Compared with the prior art, an intelligent visual guidance positioning function of a digital printer is realized by adding the machine vision of the long-line-array CIS camera, so that digital printing facilities cannot be influenced by factors such as the material deformation of a printed object, mechanical motion errors of the facilities and the like any more, thereby realizing accurate pattern printing.

Description

technical field [0001] The invention relates to a spray printing method, in particular to a digital spray printing method for embroidered cloth which can realize intelligent visual guidance. Background technique [0002] Cross-stitch printers are referred to as universal printers for short. They are usually composed of a belt guide machine and a printing module. They can be used in large-format and super-long-format printing tasks. It is a non-contact inkjet printing high-tech digital printing with objects. equipment. The main function of the cross-stitch printer is to print the embroidery pattern on the cross-stitch cloth, so that there is no need to look at the drawings during the embroidery process, and there is no need to draw grids and dot grids. Embroidery greatly shortens the embroidery time and reduces the difficulty of embroidery. [0003] It is necessary to print the pattern on each square grid accurately and without deviation. However, since the cross-stitch cl...

Problems solved by technology

However, since the cross-stitch cloth is a flexible material and has ductility, the texture of the longer and wider cloth (usually about 1.5m in width) will be distorted when it is sent to the printing area through the belt guide machine. The flatness of the cloth cannot be guaranteed during the printing process, and the distance between the printing grid and the adjacent small holes between the grids on the cross-stitch cloth is very narrow, usually about 1mm, and the positioning requirements are very high. It is easy to print on adjacent squares; coupled with the motion error between the tape guide machine and the printer itself, the actual step size of the cloth movement will be inconsistent with the theoretical step size

The above-mentioned factors cannot be solved according to the current technical means, which will eventually lead to the inability to accurately print the positioning printing pattern on the cross-stitch cloth
