Embodiment 1

[0075] Such as figure 1 and figure 2 As shown, Embodiment 1 of the present application provides an online defect detection device for a die-cutting machine, including: an acquisition module 1, a sensor module 2, a display module 3, a die-cutting machine 4 and a control processing module 5;

[0076] Wherein, the collection module 1 is arranged at the top of one side of the die-cutting machine 4, and is connected with the control processing module 5 through a cable, and is used to collect the paper image of the printed matter, and transmit the paper image of the printed matter to the Described control processing module 5, described printed matter paper image is collected under the stationary state of printed matter paper;

[0077] The sensor module 2 is arranged at the drawing gauge 6 of the die-cutting machine 4, and communicates with the control processing module 5, and is used to sense whether the printed matter paper passes through, when the printed matter paper passes thr...

Embodiment 2

[0098] Corresponding to the aforementioned embodiment 1 of an online defect detection device for a die-cutting machine, the present application also provides embodiment 2 of an online defect detection method for a die-cutting machine. Such as Figure 4a As shown, the method includes the following steps:

[0099] S101, receiving a trigger signal sent by the sensor module 2, the trigger signal is sent when the sensor module 2 senses that the printed paper passes;

[0100] S102, after delaying according to the preset delay time, send the image acquisition signal to the acquisition module 1, the preset delay time is the time required for the printed paper to move to the preset position after passing the sensor module 2 , and the printed paper is in a static state at the preset position;

[0101] S103, receiving the printed paper image collected by the collection module 1;

[0102] S104, comparing the code type information on the printed matter paper image with the code type inf...

Abstract

The invention provides a die-cutting machine online defect detection device and method.The device comprises an acquisition module, a sensor module, a displayer module, a die-cutting machine and a control processing module, the acquisition module and the sensor module are both installed on the die-cutting machine and both connected with the control processing module, and the displayer module is arranged on the side, away from the sensor module, of the die-cutting machine and connected with the control processing module; the control processing module is connected with the die cutting machine. And the control processing module is used for comparing the printed matter paper image with the standard printed image, judging whether the printed matter paper image has defects such as batch mixing, goods mixing, white paper, turning around or deviation and outputting a defect detection result. The printed matter paper image is shot in the static state of the printed matter paper, and the image-text information, the code information and the image-text position information in the printed matter paper image and the standard printed image are compared, so that the defects of the printed matter paper in the die cutting process can be more comprehensively detected, and the detection efficiency is higher.

Description

technical field [0001] The present application relates to the technical field of printed matter packaging inspection, and in particular to an online defect inspection device and method for a die-cutting machine. Background technique [0002] In the die-cutting process in the field of printed matter packaging, the operator first needs to transport the printed matter to the paper feed port of the corresponding die-cutting machine, and then the die-cutting machine can die-cut the printed matter. However, because a large number of printed materials are usually piled up in the printing factory, even for the same type of printed matter, there will be different production batches, that is, the code information is different, and the operator is prone to make mistakes when conveying the printed matter, causing the die-cutting machine to cut the printed matter If it is bad, it will form defective printed matter, and even flow into the market and cause batch quality accidents. [0003...
