Printing quality visual detection method

Abstract

The invention discloses a printing quality visual detection method, and the method includes the following content: a label quality detection system which can be installed on a printing machine, a rewinding inspection machine and a slitting machine, a detection data server and a machine table. The label quality detection system detects a label of a to-be-detected product, and defect information of the product location, image and product label is uploaded to the detection data server; the detection data server is responsible for receiving, storing and transmitting the defect information of the product label; the machine table is used for carrying a product with a defective label, and can download the defect information corresponding to the product label from the detection data server; workers can choose the defective label needed to be eliminated on the machine table and eventually complete the label uncovering and labeling processes. The beneficial effects of the printing quality visual detection method are that the whole testing process does not stop, and the overall efficiency is 2-4 times of that of a single point mode.

Description

technical field [0001] The invention relates to the application field of optical detection technology, in particular to a printing quality visual detection method. Background technique [0002] At present, most of the product label testing equipment at home and abroad are used in the single point elimination mode. In the actual application process, the simple label inspection process actually includes: rewinding, observation, judgment, defect discovery, shutdown, rejection, label replacement, etc., such as figure 2 shown. Visual inspection equipment can only improve the precision, accuracy and speed of observation, judgment and defect discovery. The longest time-consuming elimination and supplementary labeling account for about 60%-70% of the entire detection process. In the past, the label inspection system often used a single-point mode, that is, when a defect was detected, the machine would be shut down immediately, and the action of removing the label and replenishing...

AI Technical Summary

Problems solved by technology

In the past, the label inspection system often used a single-point mode, that is, when a defect was detected, it would immediately shut down, and the action of removing and refilling the label would be completed manually

This mode will often shut down to remove the label and refill the label, which greatly wastes the resources of the detection system

It is impossible to save this part of time without the cooperation of other high-precision automation equipment

At the same time, when there are many defects in the printed product, the efficiency of the testing equipment will drop significantly
