Technical Field

[0001] The present application relates to the technical field of cigarette production, and more specifically, to an online detection device for two-dimensional code printing quality. Background Art

[0002] According to the requirements of the tobacco industry, newly produced cigarette label paper must be printed with the industry's cigarette QR code, and the symbol quality requirements of the cigarette QR code should comply with the provisions of "GB / T33993-2017 Product QR Code".

[0019] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] The present application provides an online detection device for the printing quality of a two-dimensional code, which uses a camera to photograph the two-dimensional code on the trademark paper of a cigarette, and uses a two-dimensional code detector to identify and detect the two-dimensional code after displaying it on a display screen, thereby realizing automatic online detection of the two-dimensional code and greatly improving detection efficiency and production efficiency.

[0024] like Figure 1 and 2As shown, the online detection device for the printing quality of a two-dimensional code provided in the present application includes an in-place sensor, a display screen, a two-dimensional code detector, a bracket fixed on one side of a cigarette production line, and a camera arranged on the bracket.

[0025] The in-place sensor is set above the conveyor belt of the cigarette production line, and the camera is connected to the in-place sensor signal. The camera's shooting range covers the QR code of the cigarette label paper on the conveyor belt. The display screen is connected to the camera signal, and the detection window of the QR code detector faces the display screen.

[0026] Therefore, when the cigarette is transported to the detection area via the conveyor belt, the in-place sensor senses the cigarette's in-place information and then transmits the in-place information to the camera. After the preset time, the cigarette arrives directly below the camera, and the camera takes a picture of the QR code on the label paper of the cigarette, and displays the obtained QR code image on the display screen. Then the detection window of the QR code detector recognizes and detects the QR code, realizing online detection of the QR code.

[0027] Specifically, Figure 1 and 2 As shown, the bracket includes a base 10, a column 20 fixed on the base 10 and a first cantilever 70 fixed on the upper end of the column 20, and a camera 60 is fixed on the free end of the first cantilever 70, with the lens of the camera 60 facing directly downward.

[0028] As an embodiment, the camera 60 is a CCD camera.

[0029] Preferably, the free end of the first cantilever 70 is further provided with a second cantilever 80. The in-position sensor 50 is fixed on the second cantilever 80. Thus, the distance between the in-position sensor 50 and the camera 60 is very close, and the camera 60 can take pictures immediately after the in-position sensor 50 detects the in-position information, thereby improving the accuracy and efficiency of the detection.

[0030] As an embodiment, the position sensor 50 is a fiber optic sensor.

[0031] Preferably, a horizontal support plate 30 is fixed to the middle of the column 20, and the two-dimensional code detector is arranged on the support plate 30, with the detection window of the two-dimensional code detector facing upward.

[0032] On this basis, preferably, the display screen 40 is fixed on the first cantilever 70, with the screen of the display screen 40 facing downward and facing the detection window of the two-dimensional code detector.

[0033] In this preferred embodiment, the distance between the camera 60, the display screen 40 and the QR code detector is very short, which shortens the cable length between them and reduces the probability of signal transmission failure. At the same time, the online detection device has a simple and compact structure, is easy to install on the cigarette production line, and is highly practical.

[0034] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
