Tag detection device based on CIS (Corporate-Identify-System)

Abstract

The invention relates to the technical field of detection equipment, and provides a tag detection device based on a CIS (Corporate-Identify-System). The tag detection device comprises a main frame, aconveying module, a tag labeling module, a visual recognition module and an electronic control module, wherein the conveying module is used for conveying a tag belt; the tag labeling module is used for marking a tag; the visual recognition module comprises a CIS image sensor; the CIS image sensor is arranged by corresponding to the conveying path of the tag belt and is used for shooting the current corresponding tag, sending the obtained image signal to the electronic control module; and the electronic control module carries out processing analysis on the received image signal, and sending a corresponding action instruction to the tag labeling module according to an analysis result. Through the application of the CIS image sensor, a shooting focal length can be greatly reduced, complex mechanisms including a lens, a fluorescent tube, a cold cathode implementation pipe and the like are omitted, so that the device has the advantages of small volume, light weight and the like, and the tagdetection device is integrally compact, is high in space use ratio and is favorable for the miniaturization development of the tag detection device.

Description

Technical field [0001] The invention relates to the technical field of detection equipment, in particular to a CIS-based label detection device. Background technique [0002] In the process of product circulation and management, the label is usually used as the traceable mark of the product. The content of the label is generally the product's serial number, brand logo, packaging logo, etc., which is reliable and convenient for product management. The label printer continuously prints labels on the paper tape to form a label paper tape. However, in actual production, some labels in the label paper tape printed by the label printer have defects such as offset, incompleteness or illegible writing. If these labels are affixed to the product, the product cannot be traced because the label cannot be identified. Therefore, it is very necessary to screen out defective products before labeling the product. In the prior art, the label detection device uses CCD The camera detects the label...

[0002] In the process of product circulation and management, the label is usually used as the traceable mark of the product. The content of the label is generally the product serial number, brand logo, packaging logo, etc., which is reliable and convenient for product management. Usually, the label printer is used to print all The label printer prints the label continuously on the paper tape to form a label paper tape. However, in actual production, some labels have defects such as offset, incomplete or illegible writing in the label paper tape printed by the label printer. If these labels are affixed to the product, the product cannot be traced because the label cannot be recognized. Therefore, it is very necessary to screen out the defective products on the label before the product is labeled. In the prior art, the label detection device adopts CCD The camera detects the label. Since the focusing distance of the CCD camera is relatively long, the detection device needs to be provided with a sufficient space distance for the CCD camera to focus, which makes the overall volume of the detection device larger, heavier overall, not compact in structure, and low in space utilization. , takes up a lot of space
