Label printing device and image detecting, positioning and counting method thereof

Abstract

The invention discloses a label printing device and an image detecting, positioning and counting method thereof. The label printing device comprises an unwinding device, a printing device, a camera device, a winding device and a calculation storage medium. The unwinding device is composed of an unwinding mechanism and a guide mechanism, and the unwinding mechanism is used for containing blank label rolls and guiding blank label paper to an inlet of the printing device. And the printing device consists of a label edge detection sensor and a set of printing imaging device and is used for printing an image on the blank printing label. The camera device is composed of a camera assembly and a base, wherein the camera assembly is used for shooting a printed label image and transmitting image data to a computing storage medium. And the winding device is used for collecting and rewinding the printed, photographed and counted labels. The calculation storage medium is composed of a computer and a peripheral device and used for collecting, calculating and storing label images and controlling the printing device.

Description

Technical field [0001] The present invention relates to the field of label printing techniques, and more particularly to a label printer that automatically corrects automatic label image detection and image printing position by machine vision technology. Background technique [0002] Products on the label not only allows the user to have a probably understanding of the product in the look, but also quickly from the label text, good labels can make users deep memory. The label paper is arranged by the rule-arranged pre-cut blank label paper formed on the non-adhesive base paper. There is a gap between the connected blank tags, and the existing label printing device cannot automatically identify the edge of the base paper and the blank label and blank tag. Distance, in printing new labels, manual measurements need to be manually measured and printed multiple times to determine if the position of the label image is correct on the label paper, and the printing label finished product ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a label printing device and its image detection, positioning, and counting methods, so as to solve the problem that the label printing equipment in the prior art cannot automatically identify the edge of the backing paper and the blank label and the blank label. When printing a new label, it is necessary to manually measure and print several times to determine whether the position of the label image on the label paper is correct. The problem of waste, realized intelligent label detection and overprint positioning control, label finished product defect detection and automatic counting of qualified finished products, automatic identification and storage of variable data such as barcode or two-dimensional code on the label
