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

Embodiment 1

[0021] A method for visual inspection of printing quality, the method comprising the following content:

[0022] Label quality inspection system: It can be installed on printing machines, rewinding inspection machines and slitting machines. The label quality inspection system will inspect the product labels that need to be inspected, and upload the product location, image and product label defect information to the inspection data server;

[0023] Detection data server: responsible for receiving, storing and sending defect information of product labels;

[0024] Machine table: It is used to store products with defective labels, and the machine table can download the defect information corresponding to the product label from the inspection data server. Workers can select the defective labels to be removed on the machine table, and complete the final label removal and the labeling process;

[0025] Operation mode: The label quality inspection system detects the labels of the p...

Embodiment 2

[0039] The parameter index in the actual work of the label quality detection system can be set as:

[0040] Width: 200mm

[0041] Light source: symmetrical light source + laser light source

[0042] Rewinding platform: adopt CR9035B rewinding platform

[0043] Camera: PC30-04K80*2 camera

[0044] Detection speed: 50 m / min

[0045] Resolution:

[0046] Horizontal resolution: 0.05mm

[0047] Vertical resolution: 0.05mm

[0048] Detection object: high-end electronic label. Other parts are identical with embodiment 1.

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...
