These embodiments are implemented based on the technical solution of the present invention, providing detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0022] Example 1

Figure 1 The printing system is installed on the conveyor belt 1 for product production and includes a variable QR code generation component 2, a first curing component 3, an invisible code generation component 4, and a second curing component 5 arranged sequentially along the travel direction of the conveyor belt 1.

[0024] In this embodiment, the variable QR code generation component 2 is a variable QR code inkjet printer. Specifically, the variable QR code inkjet printer is a UV inkjet printer, model Founder full-sheet inkjet printer, which can be used to print visible QR codes, and its size, resolution, and contrast can be set.

[0025] In this embodiment, the first curing component 3 is a UV curing lamp.

[0026] In this embodiment, the stealth code generation component 4 is a stealth code inkjet printer.

[0027] In this embodiment, the second curing component 5 is an infrared curing lamp.

[0028] Example 2

[0029] This embodiment is basically the same as Embodiment 1, except that the printing system in this embodiment also includes a vision inspection component 6, which is located downstream of the second curing component 5. For details, see [link to documentation]. Figure 2 .

[0030] In this embodiment, the visual inspection component 6 includes a visual camera, a stealth code display light source, a laser emitter, and a laser receiver; the visual camera, stealth code display light source, laser emitter, and laser receiver are positioned above the conveyor belt 1, and the visual camera captures the variable QR code and stealth code generated on the product to determine the generation quality of the variable QR code and stealth code.

[0031] In this embodiment, the invisible code display light source is an infrared light source or an ultraviolet light source.

[0032] Example 3

[0033] This embodiment is basically the same as Embodiment 2, except that the printing system further includes a data recognition component, which is located downstream of the vision inspection component 6. See [link to specific structure] for details. Figure 3 .

[0037] Specific work process:

[0038] 1. Product Positioning: A sensor triggers the printing signal to ensure accurate positioning of the product when it reaches the QR code generation component. The sensor is a photoelectric sensor; when the product passes through the sensor's detection area, it blocks or reflects light, triggering the printing signal.

[0039] 2. Synchronous printing

[0040] First station: A variable QR code inkjet printer prints visible QR codes (on the surface or in a specific area).

[0041] Second station: The invisible code inkjet printer prints invisible codes near the QR code or on the overlay layer (visual interference must be avoided).

[0042] 3. Online testing

[0043] The visual inspection component 6 and the data recognition component scan the QR code and the invisible code respectively to verify readability and association accuracy.

[0044] 4. Data association and import

[0045] The QR code content, invisible code data, and timestamp are bound and then uploaded to the database.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments.
