Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment for cigarette box sealing equipment, and in particular relates to a cigarette box barcode recognition device based on image recognition. Background Art

[0002] During the production process, cigarette industrial enterprises will produce multiple specifications of products at the same time. Different specifications of cigarette cartons are packaged into boxes by corresponding box sealing machines. In this process, an indispensable auxiliary material is needed - cigarette boxes. However, due to the similar appearance and color of cigarette boxes, there may be a mismatch when adding them manually, that is, adding a cigarette box of Category A specifications to the box sealing machine that produces Category B specifications, resulting in the phenomenon that the specifications of the cigarette cartons and cigarette boxes do not correspond. If such products enter the market, it will have a negative impact on the corporate image and cause certain economic losses.

[0003] To solve this problem, the patent "Cigarette Case Barcode Recognition and Alarm System for Cigarette Enterprise Case Sealing Machine" discloses a method of using a barcode scanner to identify the cigarette case barcode and match it with the set product specification barcode. When the match fails, an alarm is issued and the case sealing machine is shut down to avoid the phenomenon of wrong brand. However, during the production and transportation of cigarette cases, the barcode may be partially unclear, worn, bent or broken. When the scanning position happens to fall on these parts, the barcode may not be recognized. At this time, the system will mistakenly believe that the cigarette case is a wrong brand cigarette case, which will cause unnecessary equipment shutdown. Summary of the invention

[0004] In order to solve the above-mentioned technical problems existing in the prior art, the utility model proposes a cigarette box barcode recognition device based on image recognition. When using image recognition technology to recognize barcodes, it can automatically identify and correct some common errors and interferences, such as barcode tilt, blur, stains, etc., thereby improving the success rate of cigarette box barcode recognition and reducing unnecessary equipment downtime caused by the inability to recognize cigarette box barcodes.

[0005] The technical solution adopted by the utility model is:

[0006] A cigarette box barcode recognition device based on image recognition, characterized in that it includes an industrial computer, a camera, a fill light, a display screen and a sealing machine PLC, the industrial computer is installed in the electric control cabinet of the sealing machine, the first communication port of the industrial computer is connected to the camera, the second communication port of the industrial computer is connected to the display screen, the first trigger output signal interface and the second trigger output signal interface of the industrial computer are respectively connected to the camera and the fill light; the comparison output signal interface of the industrial computer is connected to the stop input signal interface of the sealing machine PLC, and the input signal interface of the industrial computer is connected to the in-place output signal interface of the sealing machine PLC.

[0007] Furthermore, the camera and the fill light are respectively installed at the fixed end of the carton sealing machine.

[0008] Furthermore, the parameters of the camera are F1.4 / 25mm, and the installation position is 100 cm away from the smoke box.

[0009] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0010] Compared with barcode scanners for identifying cigarette box barcodes, the cigarette box barcode recognition system based on image recognition proposed by the utility model can automatically identify and correct some common errors and interferences, such as barcode tilt, blur, stains, etc., thereby improving the success rate of cigarette box barcode recognition. The system has a simple structure, is easy to maintain, and has good adaptability and promotion. BRIEF DESCRIPTION OF THE DRAWINGS
