TECHNICAL FIELD

[0001] The present application relates to the field of label printing technology, in particular to a traceability code visual detection system. BACKGROUND

[0002] In modern society, the traceability code on the commodity can provide the production country, manufacturer, commodity name, production date, price and many other information of the commodity, so it plays an important role in commodity inspection or cash register. The traceability code is a graphical symbol composed of dark bars and light spaces. After purchasing the commodity, the buyer can scan the bar code through the software in the handheld terminal to obtain the relevant information of the commodity.

[0003] In the prior art, during the production and processing process, the traceability code is often sprayed on the packaging paper by a printing device. The traceability code is randomly generated in the control host. The printing device is connected with the data output end of the control host. The traceability code can be correspondingly sprayed on the packaging paper through the printing device. In order to ensure the accuracy of the traceability code, the operator often needs to carry out sampling inspection on the traceability code on the packaging paper by using a handheld detection device. During the sampling inspection, the operator randomly selects the packaging paper and scans the traceability code on the packaging paper by using the handheld detection device to determine whether the traceability code on the packaging paper has defects such as code redundancy, white line defect, black line defect, appearance defect, position deviation defect and data error.

[0036] The following will be described in detail in combination with the accompanying drawings. Figures 1-2 The present application will be further described in detail.

[0037] EMBODIMENT

[0038] The embodiment of the present application discloses a traceability code visual detection system. Referring to Figures 1-2The device mainly comprises a rack 1 fixedly installed at an outlet of a printing device, a horizontal passing platform 2 fixedly installed on the rack 1, and a control panel 3 fixedly installed on the rack 1 and used for inputting a set interval number. A counting module fixedly installed on the rack 1 is in signal connection with a signal output end of the control panel 3, used for detecting the number of color marks on the packaging paper and outputting a detection control signal when the number of color marks reaches the set interval number or an integer multiple of the set interval number. An image detection module fixedly installed on the rack 1 is arranged above the passing platform 2, used for receiving the detection control signal and detecting the printing quality of the traceability code. A display 4 is in signal connection with a signal output end of the image detection module, used for receiving the detection result output by the image detection module and displaying.

[0039] In the actual production process, when the packaging paper is printed by the printing device and has not been cut, the packaging paper continuously, uniformly and sequentially passes through the counting module and the image detection module. The counting module detects the number of color marks on the packaging paper passing below the counting module. When the number of color marks reaches the set interval number or an integer multiple of the set interval number, the image detection module receives the detection control signal, collects the image data of the traceability code on the packaging paper, and compares with the preset printing image of the control host.

[0047] The image collector 6 can collect image data of the traceable code on the wrapping paper, and the image processor can compare the collected image data of the traceable code with preset image data of the control host, thereby comparing the traceable code on the wrapping paper and achieving the technical effect of automatically comparing the traceable code.

[0048] In the embodiment, the data output end of the image processor is data-connected with a memory, which receives and stores the detection result data. Through the memory, the detection result data can be stored, thereby facilitating subsequent operation personnel in tracing the detection result data.

[0049] With reference to Figure 2 , the mounting top plate 7 is fixedly mounted with a light supplementing lamp 8. When the indoor light intensity is low, the light supplementing lamp 8 can be turned on to provide a clear and bright field of view for the image collector 6.

[0050] With reference to Figure 1 , the top of the rack 1 is fixedly mounted with a connecting plate 11, the top of the connecting plate 11 is provided with a positioning groove 12 matched with the mounting top plate 7, and the mounting top plate 7 is fixedly mounted on the connecting plate 11 through bolts. Through the positioning groove 12 on the connecting plate 11, the mounting top plate 7 can be quickly installed by the operation personnel.
